The Offer is being made pursuant to an Agreement and Plan of Merger, dated as of February 21, 2025 (as it may be amended, supplemented or otherwise modified from time to time, the “Merger Agreement”), by and among the Company, Parent and Merger Sub, pursuant to which, as soon as practicable following the date and

time of the irrevocable acceptance for payment (the “Acceptance Time”) by Merger Sub of Shares validly tendered and not validly withdrawn pursuant to and subject to the conditions set forth in Section 15 – “Conditions to the Offer” (collectively, the “Offer Conditions”), subject to the satisfaction or, if permitted by applicable law, waiver of certain conditions, and in any event no later than one business day thereafter, Merger Sub will merge with and into the Company (such merger, the “Merger”), and the Company will survive the Merger as an indirect wholly owned subsidiary of Parent (the “Surviving Corporation”), on the terms and subject to the conditions set forth in the Merger Agreement.

The Merger will be governed by Section 251(h) of the Delaware General Corporation Law (the “DGCL”) and will be effected by Merger Sub and the Company without a stockholder vote pursuant to the DGCL as soon as practicable following the Acceptance Time, subject to the satisfaction or, if permitted by applicable law, waiver of certain conditions, and in any event no later than one business day thereafter.

As a result of the Merger, the Company will cease to be a publicly traded company and will become an indirect wholly owned subsidiary of Parent.

Pursuant to the terms of the Merger Agreement, each restricted stock unit with respect to Shares that is, at the time of determination, subject to vesting or forfeiture conditions and that is not a Company PSU (as defined below) (but including, for clarity, any Company PSU that is subject solely to service-based vesting conditions as of the Effective Time) (each, a “Company RSU”) that is outstanding as of immediately prior to the Effective Time, will accelerate and become fully vested effective immediately prior to, and contingent upon the occurrence of, the Effective Time. Effective as of immediately prior to the Effective Time, each Company RSU that is outstanding immediately prior thereto shall, by virtue of the Merger, automatically and (except as otherwise provided in the Merger Agreement) without any action on the part of the Company, Parent or the holder thereof, be canceled and terminated and converted into the right to receive from the Surviving Corporation, subject to the terms of the Merger Agreement, (A) an amount in cash (without interest) equal to the product obtained by multiplying (1) the aggregate number of Shares underlying such Company RSU immediately prior to the Effective Time, by (2) the Closing Amount; plus (B) one CVR with respect to each Share subject to such Company RSU immediately prior to the Effective Time (in each case, as adjusted to reflect any increases to the Offer Price).

terminated and converted into the right to receive from the Surviving Corporation, subject to the terms of the

Merger Agreement, (A) an amount in cash (without interest) equal to the product obtained by multiplying (1) the aggregate number of Shares underlying such Company PSU immediately prior to the Effective Time (assuming that the applicable performance goals have been deemed to be achieved at the greater of target and actual level of performance as determined by the compensation committee of the board of directors of the Company (the “Company Board”) in its discretion), by (2) the Closing Amount; plus (B) one CVR with respect to each such Share subject to such Company PSU immediately prior to the Effective Time (in each case, as adjusted to reflect any increases to the Offer Price). Other than the Company PSUs addressed by the preceding sentence, each other Company PSU that is outstanding immediately prior to the Effective Time shall by virtue of the Merger automatically and (except as otherwise provided in the Merger Agreement) without any action on the part of the Company, Parent or the holder thereof, be canceled and terminated without any consideration payable therefor.

Pursuant to the terms of the Merger Agreement, effective as of immediately prior to the Effective Time, each stock option to purchase Shares (each, a “Company Option”) that is outstanding and unexercised immediately prior thereto shall by virtue of the Merger automatically and (except as otherwise provided in the Merger Agreement) without any action on the part of the Company, Parent or the holder thereof, be canceled and terminated without any consideration payable therefor.

Pursuant to the terms of the Merger Agreement, at the Effective Time, each outstanding warrant to purchase or otherwise acquire Shares that is outstanding and unexercised as of immediately prior to the Effective Time shall be canceled and extinguished for no consideration pursuant to the terms thereof.

Under no circumstances will interest be paid on the purchase price for the Shares, including by reason of any extension of the Offer or any delay in making payment for the Shares.

The Offer is subject to the Offer Conditions, including, but not limited to, (i) there having been validly tendered and not validly withdrawn in accordance with the terms of the Offer, and “received” by the “depository” for the Offer (as such terms are defined in Section 251(h) of the DGCL), a number of Shares that, together with the other Shares then owned by Parent, Merger Sub and any of their direct or indirect wholly owned subsidiaries, represents at least one more Share than 50% of the total number of outstanding Shares at the Expiration Time (defined as one minute after 11:59 p.m., New York City time, on April 4, 2025, unless the Offer is extended or earlier terminated pursuant to and in accordance with the Merger Agreement, in which case the term “Expiration Time” means such subsequent time) (the “Minimum Condition”), (ii) the required regulatory approvals applicable to the Transactions contemplated by the Merger Agreement under any foreign antitrust law of certain specified jurisdictions shall have been obtained and (iii) no governmental authority of competent and applicable jurisdiction shall have (A) enacted, issued or promulgated any law that is in effect as of immediately prior to the Expiration Time and has the effect of making the Offer, the acquisition of Shares by Parent or Merger Sub, or the Merger illegal or which has the effect of prohibiting or otherwise preventing the consummation of the Offer, the acquisition of Shares by Parent or Merger Sub, or the Merger, or (ii) issued or granted any order that is in effect as of immediately prior to the Expiration Time and has the effect of making the Offer, the acquisition of Shares by Parent or Merger Sub, or the Merger illegal or which has the effect of prohibiting or otherwise preventing the consummation of the Offer, the acquisition of Shares by Parent or Merger Sub, or the Merger. The Offer is not subject to any financing condition.

Tendering stockholders who are record owners of their Shares and who tender directly to Equiniti Trust Company, LLC (the “Depositary”) will not be obligated to pay brokerage fees or commissions or, except as otherwise provided in Instruction 6 of the Letter of Transmittal, stock transfer taxes with respect to the purchase of Shares by Merger Sub pursuant to the Offer. Stockholders who hold their Shares through a broker, banker or other nominee should consult such institution as to whether it charges any service fees or commissions.

The Company Board has unanimously (i) determined that the Merger Agreement and the transactions contemplated thereby, including the Offer and the Merger (the “Transactions”), are advisable, fair to and in the best interests of the Company and its stockholders, and declared it advisable for the Company to enter into the Merger Agreement and consummate the Transactions contemplated therein, (ii) approved and declared advisable the execution and delivery by the Company of the Merger Agreement, the performance by the Company of its covenants and agreements contained therein and the consummation of the Transactions contemplated by the Merger Agreement upon the terms and subject to the conditions contained therein, (iii) resolved that the Merger Agreement and the Merger be governed by Section 251(h) of the DGCL and that the Merger be effected as soon as practicable following the Acceptance Time without a vote of the Company stockholders, and (iv) resolved, subject to the terms and conditions set forth in the Merger Agreement, to recommend that the holders of the Shares accept the Offer and tender their Shares to Merger Sub pursuant to the Offer, which resolutions, except to the extent expressly permitted by the Merger Agreement, have not been rescinded, modified or withdrawn in any way.

17

More complete descriptions of the Company Board’s reasons for authorizing and approving the Merger Agreement and the consummation of the Transactions contemplated by the Merger Agreement, including the Offer and the Merger, are set forth in the Company’s Solicitation/Recommendation Statement on Schedule 14D-9 (as it may be amended, supplemented or otherwise modified from time to time, the “Schedule 14D-9”) that is being mailed to you together with this Offer to Purchase. Stockholders should carefully read the information set forth in the Schedule 14D-9, including the information set forth in Item 4 thereof under the sub-headings “Background of the Offer and the Merger” and “Reasons for Recommendation.”

The Company Board has received the opinion of Leerink Partners LLC (“Leerink”), dated the date of the Merger Agreement, to the effect that, as of such date and based upon and subject to the qualifications, limitations, assumptions and other matters set forth therein, the Closing Amount to be paid to the Company stockholders (other than holders of Canceled Shares and Dissenting Shares) pursuant to the Merger Agreement was fair, from a financial point of view, to such holders. It was agreed and understood that such opinion is for the benefit of the Company Board and may not be relied upon by Parent or Merger Sub. The full text of the written opinion of Leerink, dated February 21, 2025, sets forth the assumptions made, procedures followed, matters considered and qualifications and limitations on the review undertaken by Leerink in connection with its opinion and is attached as Annex I to the Schedule 14D-9.

Unless the context indicates otherwise, in this Offer to Purchase, we use the terms “us,” “we” and “our” to refer to Merger Sub and, where appropriate, Parent. We use the term “Merger Sub” to refer to Beacon Merger Sub, Inc. alone, the term “Parent” to refer to Beacon Parent Holdings, L.P. alone and the phrase “the Company” to refer to bluebird bio, Inc. alone.

This Offer to Purchase and the related Letter of Transmittal contain important information that should be read carefully in its entirety before any decision is made with respect to the Offer.

THE TENDER OFFER

1. Terms of the Offer

Merger Sub is offering to purchase all of the outstanding Shares of the Company at the Offer Price, in cash, subject to applicable withholding taxes and without interest thereon. On the terms and subject to the conditions to the Offer (including, if the Offer is extended or amended, the terms and conditions of such extension or amendment), Merger Sub shall (and Parent shall cause Merger Sub to), at or as promptly as practicable following the Expiration Time (as it may be extended in accordance with the Merger Agreement), but in any event within one business day thereof, irrevocably accept for payment, and, at or as promptly as practicable following the Acceptance Time, but in any event within one business day thereof, pay for, all Shares that are validly tendered and not validly withdrawn (as described in Section 4 – “Withdrawal Rights”) pursuant to the Offer.

The Offer is subject to the Offer Conditions, including, but not limited to, the Minimum Condition, the Regulatory Approvals Condition and the No Injunction Condition.

Parent and Merger Sub expressly reserve the right, at any time and from time to time, to waive, in whole or in part, any of the Offer Conditions, to make any change in the terms of or conditions to the Offer in a manner consistent with the terms of the Merger Agreement or to increase the Offer Price; provided, however, that notwithstanding the foregoing or anything to the contrary set forth therein, without the prior written consent of the Company, Parent and Merger Sub may not (and Parent shall not permit Merger Sub to) (i) waive or modify specified Offer Conditions, including the Minimum Condition or the No Injunction Condition; or (ii) make any change in the terms of or conditions to the Offer that: (A) changes the form of consideration to be paid in the Offer; (B) decreases the Offer Price or the number of Shares sought in the Offer; (C) extends the Offer or the Expiration Time, except as permitted or required by the Merger Agreement; (D) imposes conditions or requirements on the Offer other than the Offer Conditions, as described in Section 15 – “Conditions to the Offer”; (E) amends or modifies any term or condition of the Offer in any manner that is (or would reasonably be expected to be) material and adverse to the Company stockholders; or (F) would, individually or in the aggregate, reasonably be expected to prevent or materially delay the consummation of the Offer or prevent, materially delay or materially impair the ability of Parent or Merger Sub to consummate the Offer, the Merger or the other Transactions contemplated by the Merger Agreement.

The Merger Agreement contains provisions that govern the circumstances under which Merger Sub is required to extend the Offer. Specifically, the Merger Agreement provides that:

19

Notwithstanding the foregoing, the Merger Agreement further provides that Parent and Merger Sub may not extend the Offer beyond the Termination Date without the prior written consent of the Company in its sole and absolute discretion. The “Initial Termination Date” means April 25, 2025 and as such date may be extended pursuant to the Merger Agreement or by the mutual written consent of the parties thereto, the “Termination Date”. See Section 1 – “Terms of the Offer” and Section 11 – “The Merger Agreement; Other Agreements.”

If we extend the Offer, are delayed in our acceptance for payment of or payment for the Shares or are unable to accept Shares for payment pursuant to the Offer for any reason, then, without prejudice to our rights under the Offer and the Merger Agreement, the Depositary may retain tendered Shares on our behalf, and such Shares may not be withdrawn except to the extent that tendering stockholders are entitled to withdrawal rights as described in Section 4 – “Withdrawal Rights.” However, our ability to delay the payment for the Shares that we have accepted for payment is limited by Rule 14e-1(c) under the Exchange Act, which requires us to pay the consideration offered or return the securities deposited by or on behalf of stockholders promptly after the termination or withdrawal of the Offer.

Any extension, delay, termination or amendment of the Offer will be followed as promptly as practicable by a public announcement thereof, and such announcement in the case of an extension will be made no later than 9:00 a.m., New York City time, on the business day after the previously scheduled Expiration Time. Without limiting the manner in which we may choose to make any public announcement, we intend to make announcements regarding the Offer by issuing a press release and making any appropriate filing with the SEC.

If we make a material change in the terms of the Offer or the information concerning the Offer or if we waive a material condition of the Offer, we will disseminate additional tender offer materials and extend the Offer, in each case, if and to the extent required by Rules 14d-4(d)(1), 14d-6(c) and 14e-1 under the Exchange Act. The minimum period during which the Offer must remain open following material changes in the terms of the Offer or information concerning the Offer, other than a change in price or a change in percentage of securities sought, will depend upon the facts and circumstances, including the relative materiality of the terms or information changes. We understand that in the SEC’s view an offer should remain open for a minimum of five business days from the date the material change is first published, sent or given to holders of Shares, and with respect to a change in price or a change in the percentage of securities sought, a minimum ten business day period generally is required to allow for adequate dissemination to holders of the Shares and investor response.

If, on or before the Expiration Time, we increase the consideration being paid for the Shares accepted for payment in the Offer, such increased consideration will be paid to all holders whose Shares are purchased in the Offer, whether or not such Shares were tendered before the announcement of the increase in consideration.

The obligation of Merger Sub to accept for payment and pay for Shares validly tendered and not validly withdrawn pursuant to the Offer is subject to the satisfaction of the Offer Conditions. Notwithstanding any other term of the Offer or the Merger Agreement, Merger Sub will not be required to, and Parent will not be required to cause Merger Sub to, accept for payment or, subject to any applicable rules and regulations of the SEC, including Rule 14e-1(c) under the Exchange Act, pay for any tendered Shares if any of the Offer Conditions has not been satisfied at the scheduled Expiration Time.

Under certain circumstances described in the Merger Agreement, Parent or the Company may terminate the Merger Agreement and Parent and Merger Sub may terminate the Offer. The Offer may not be terminated prior

20

to the Expiration Time unless the Merger Agreement is validly terminated in accordance with the terms of the Merger Agreement. If Parent and Merger Sub terminate the Offer, the Depositary will promptly return, in accordance with applicable law, all Shares that have been tendered in the Offer to the registered holders of such Shares.

The Company has provided us with its stockholder list and security position listings for the purpose of disseminating the Offer to holders of the Shares. This Offer to Purchase and the related Letter of Transmittal, as well as the Schedule 14D-9, will be mailed to record holders of the Shares whose names appear on the stockholder list and will be furnished for subsequent transmittal to beneficial owners of the Shares to brokers, dealers, commercial banks, trust companies and similar persons whose names, or the names of whose nominees, appear on the stockholder list or, if applicable, who are listed as participants in a clearing agency’s security position listing.

2. Acceptance for Payment and Payment for the Shares

Subject to the terms of the Offer and the Merger Agreement, including the satisfaction or, to the extent waivable by Parent or Merger Sub, waiver of each of the Offer Conditions, Merger Sub shall (and Parent shall cause Merger Sub to), at or as promptly as practicable following the Expiration Time (as it may be extended in accordance with the Merger Agreement), but in any event within one business day thereof, irrevocably accept for payment, and, at or as promptly as practicable following the Acceptance Time, but in any event within one business day thereof, pay for, all Shares that are validly tendered and not validly withdrawn (as described in Section 4 – “Withdrawal Rights”) pursuant to the Offer. Subject to compliance with Rule 14e-1(c) under the Exchange Act, as applicable, and with the Merger Agreement, we expressly reserve the right to delay payment for the Shares in order to comply in whole or in part with any applicable law or regulation. See Section 16 – “Certain Legal Matters; Regulatory Approvals.”

In all cases, we will pay for Shares validly tendered and not validly withdrawn and accepted for payment pursuant to the Offer only after timely receipt by the Depositary of (i) the certificates evidencing such Shares (the “Share Certificates”), (ii) confirmation of a book-entry transfer of such Shares into the Depositary’s account at The Depository Trust Company (“DTC”) (such a confirmation, a “Book-Entry Confirmation”) pursuant to the procedures set forth in Section 3 – “Procedures for Accepting the Offer and Tendering Shares,” with respect to Shares held in “street” name, (iii) in the case of Share Certificates, the Letter of Transmittal, properly completed and duly executed, with any required signature guarantees and (iv) any other documents required by the Letter of Transmittal or, in the case of a book-entry transfer of Shares held in “street” name, an Agent’s Message (as defined below) in lieu of the Letter of Transmittal and such other documents.

The term “Agent’s Message” means a message transmitted through electronic means by DTC in accordance with the normal procedures of DTC to, and received by, the Depositary and forming part of a Book-Entry Confirmation, that states that DTC has received an express acknowledgment from the participant in DTC tendering the Shares that are the subject of such Book-Entry Confirmation that such participant has received and agrees to be bound by the terms of, the Letter of Transmittal, and that Merger Sub may enforce such agreement against such participant. The term “Agent’s Message” also includes any hard copy printout evidencing such message generated by a computer terminal maintained at the Depositary’s office.

For purposes of the Offer, we will be deemed to have accepted for payment, and thereby purchased, Shares validly tendered and not validly withdrawn to Merger Sub as, if and when we give oral or written notice to the Depositary of our acceptance for payment of such Shares pursuant to the Offer. On the terms and subject to the Offer Conditions, payment for the Shares accepted for payment pursuant to the Offer will be made by deposit of the Offer Price for such Shares with the Depositary, which will act as agent for tendering stockholders for the purpose of receiving payments from us and transmitting such payments to tendering stockholders whose Shares have been accepted for payment. If we extend the Offer, are delayed in our acceptance for payment of or payment for the Shares or are unable to accept the Shares for payment pursuant to the Offer for any reason, then,

21

without prejudice to our rights under the Offer and the Merger Agreement, the Depositary may retain tendered Shares on our behalf, and such Shares may not be withdrawn except to the extent that tendering stockholders are entitled to withdrawal rights as described in Section 4 – “Withdrawal Rights.” However, our ability to delay the payment for the Shares that we have accepted for payment is limited by Rule 14e-1(c) under the Exchange Act, which requires us to pay the consideration offered or return the securities deposited by or on behalf of stockholders promptly after the termination or withdrawal of the Offer. Under no circumstances will we pay interest on the Offer Price for Shares, including by reason of any extension of the Offer or any delay in making such payment.

At or prior to the Effective Time, Parent will execute the CVR Agreement governing the terms of the CVRs with the Rights Agent. Parent will be not required to deposit any funds related to any CVR with the Rights Agent unless and until such deposit is required pursuant to the terms of the CVR Agreement. For more information on the CVRs, see Section 11 – “The Merger Agreement; Other Agreements.”

If any tendered Shares are not accepted for payment pursuant to the terms and conditions to the Offer for any reason, or if Share Certificates are submitted evidencing more Shares than are tendered, Share Certificates representing unpurchased Shares will be returned, without expense to the tendering stockholder (or, in the case of Shares tendered by book-entry transfer into the Depositary’s account at DTC pursuant to the procedure set forth in Section 3 – “Procedures for Accepting the Offer and Tendering Shares,” such Shares will be credited to an account maintained at DTC), as promptly as practicable following the expiration or termination of the Offer.

3. Procedures for Accepting the Offer and Tendering Shares

Valid Tenders. In order for a stockholder to validly tender Shares pursuant to the Offer, you must follow these instructions:

Book-Entry Transfer. The Depositary will establish an account with respect to the Shares at DTC for purposes of the Offer within two business days after the date of this Offer to Purchase. Any financial institution that is a participant in the system of DTC may make a book-entry delivery of the Shares by causing DTC to transfer such Shares into the Depositary’s account at DTC in accordance with DTC’s procedures for such transfer. However, although delivery of the Shares may be effected through book-entry transfer at DTC, either the Letter of Transmittal, properly completed and duly executed, together with any required signature guarantees and any other required documents, or an Agent’s Message in lieu of the Letter of Transmittal and such other documents, must, in any case, be received by the Depositary at one of its addresses set forth on the back cover of this Offer to Purchase prior to the Expiration Time. Delivery of documents to DTC does not constitute delivery to the Depositary.

22

No Guaranteed Delivery. We are not providing for guaranteed delivery procedures. Therefore, Company stockholders must allow sufficient time for the necessary tender procedures to be completed prior to the Expiration Time. In addition, for Company stockholders who are registered holders, the Letter of Transmittal, properly completed and duly executed, together with any required signature guarantees and any other documents required by the Letter of Transmittal (or, in the case of a book-entry transfer, an Agent’s Message in lieu of the Letter of Transmittal and such other documents) must be received by the Depositary prior to the Expiration Time. Company stockholders must tender their Shares in accordance with the procedures set forth in this Offer to Purchase and the Letter of Transmittal. Tenders received by the Depositary after the Expiration Time will be disregarded and of no effect.

Signature Guarantees for Shares. No signature guarantee is required on the Letter of Transmittal (i) if the Letter of Transmittal is signed by the registered holder(s) (which term, for purposes of this Section 3, includes any participant in DTC’s systems whose name appears on a security position listing as the owner of the Shares) of the Shares tendered therewith, unless such holder or holders have completed either the box entitled “Special Delivery Instructions” or the box entitled “Special Payment Instructions” on the Letter of Transmittal or (ii) if the Shares are tendered for the account of a financial institution (including most commercial banks, savings and loan associations and brokerage houses) that is a member in good standing of the Security Transfer Agents Medallion Program or any other “eligible guarantor institution,” as such term is defined in Rule 17Ad-15 of the Exchange Act (each an “Eligible Institution”). In all other cases, all signatures on a Letter of Transmittal must be guaranteed by an Eligible Institution. See Instruction 1 of the Letter of Transmittal. If a Share Certificate is registered in the name of a person or persons other than the signers of the Letter of Transmittal, or if payment is to be made or delivered to, or a Share Certificate not accepted for payment or not tendered is to be issued in, the name(s) of a person or persons other than the registered holder(s), then the Share Certificate must be endorsed or accompanied by appropriate duly executed stock powers, in either case signed exactly as the name(s) of the registered holder(s) appear on the Share Certificate, with the signature(s) on such Share Certificate or stock powers guaranteed by an Eligible Institution as provided in the Letter of Transmittal. See Instructions 1 and 5 of the Letter of Transmittal.

Notwithstanding any other provision of this Offer, payment for the Shares accepted for payment pursuant to the Offer will in all cases only be made after timely receipt by the Depositary of (i) Share Certificates or a Book-Entry Confirmation of a book-entry transfer of such Shares into the Depositary’s account at DTC pursuant to the procedures set forth in this Section 3, (ii) in the case of Share Certificates, the Letter of Transmittal, properly completed and duly executed, with any required signature guarantees, and any other documents required by the Letter of Transmittal, or (iii) in the case of a book-entry transfer, an Agent’s Message in lieu of the Letter of Transmittal and such other documents.

The method of delivery of the Shares (or Share Certificates), the Letter of Transmittal and all other required documents, including delivery through DTC, is at the election and risk of the tendering stockholder. Delivery of the Shares (or Share Certificates), the Letter of Transmittal and all other required documents will be deemed made, and risk of loss thereof shall pass, only when they are actually received by the Depositary (including, in the case of a book-entry transfer of Shares, by Book-Entry Confirmation with respect to such Shares). If such delivery is by mail, it is recommended that the Shares (or Share Certificates), the Letter of Transmittal and all other required documents be sent by properly insured registered mail with return receipt requested. In all cases, sufficient time should be allowed to ensure timely delivery.

Tender Constitutes Binding Agreement. The tender of Shares pursuant to any one of the procedures described above will constitute the tendering stockholder’s acceptance of the Offer, as well as the tendering stockholder’s representation and warranty that such stockholder has the full power and authority to tender and assign the Shares tendered, as specified in the Letter of Transmittal. Our acceptance for payment of Shares tendered pursuant to the Offer will constitute a binding agreement between the tendering stockholder and us on the terms and subject to the conditions to the Offer.

23

Determination of Validity. All questions as to the validity, form, eligibility (including time of receipt) and acceptance for payment of any tender of Shares will be determined by us, in our sole discretion, which determination will be final and binding on all parties, subject to any judgment of any court of competent jurisdiction. We reserve the absolute right to reject any and all tenders determined by us not to be in proper form or the acceptance for payment of which may, in our opinion, be unlawful. We also reserve the absolute right to waive any defect or irregularity in the tender of any Shares of any particular stockholder, whether or not similar defects or irregularities are waived in the case of other stockholders. No tender of Shares will be deemed to have been validly made until all defects and irregularities have been cured or waived to our satisfaction. None of Merger Sub, Parent or any of their respective affiliates or assigns, the Depositary, Innisfree M&A Incorporated, the information agent for the Offer (the “Information Agent”) or any other person will be under any duty to give notification of any defects or irregularities in tenders or incur any liability for failure to give any such notification. Subject to applicable law as applied by a court of competent jurisdiction and the terms of the Merger Agreement, our interpretation of the terms and conditions to the Offer (including the Letter of Transmittal and the instructions thereto) will be final and binding.

Appointment as Proxy. By executing the Letter of Transmittal as set forth above, the tendering stockholder will irrevocably appoint designees of Merger Sub as such stockholder’s attorneys-in-fact and proxies in the manner set forth in the Letter of Transmittal, each with full power of substitution, to the full extent of such stockholder’s rights with respect to the Shares tendered by such stockholder and accepted for payment by Merger Sub and with respect to any and all other Shares or other securities or rights issued or issuable in respect of such Shares. All such powers of attorney and proxies will be considered irrevocable and coupled with an interest in the tendered Shares. Such appointment will be effective when, and only to the extent that, we accept payment for the Shares tendered by such stockholder as provided herein. Upon such appointment, all prior powers of attorney, proxies and consents given by such stockholder with respect to such Shares or other securities or rights will, without further action, be revoked and no subsequent powers of attorney, proxies, consents or revocations may be given by such stockholder (and, if given, will not be deemed effective). The designees of Merger Sub will thereby be empowered to exercise all voting and other rights with respect to such Shares and other securities or rights, including, without limitation, in respect of any annual, special or adjourned meeting of Company stockholders, actions by written consent in lieu of any such meeting or otherwise, as they in their sole discretion deem proper. We reserve the right to require that, in order for Shares to be deemed validly tendered, immediately upon our acceptance for payment of such Shares, Merger Sub must be able to exercise full voting, consent and other rights with respect to such Shares and other related securities or rights, including voting at any meeting of Company stockholders.

Stock Options, Other Equity Awards and Warrants. Pursuant to the terms of the Merger Agreement, effective as of immediately prior to the Effective Time, (i) each Company Option that is outstanding and unexercised immediately prior thereto will by virtue of the Merger automatically be canceled and terminated without any consideration payable therefor, (ii) each Company RSU that is outstanding as of immediately prior to the Effective Time (including, for clarity, any Company PSUs that are subject solely to service-vesting conditions as of the Effective Time) (a) will accelerate and become fully vested, and (b) will automatically be canceled and converted into the right to receive the RSU Consideration, and (iii) each Company PSU that is outstanding and vested as of immediately prior to the Effective Time (or that will become vested as required under the terms of the applicable Company stock plan and/or governing award or other agreements currently in place as of the date of the Merger Agreement), will automatically be canceled and converted into the right to receive the PSU Consideration and each other Company PSU that is outstanding immediately prior to the Effective Time will be canceled and terminated without any consideration payable therefor. Pursuant to the terms of the Merger Agreement, at the Effective Time, each Company Warrant that is outstanding and unexercised as of immediately prior to the Effective Time shall be canceled and extinguished for no consideration pursuant to the terms thereof.

24

Information Reporting and Backup Withholding. Payments made to stockholders of the Company in the Offer or the Merger may be subject to information reporting and may be subject to backup withholding (currently at a rate of 24%) or other withholding of U.S. federal income tax on payments for Shares made in the Offer or the Merger. In addition, payments with respect to a CVR may be subject to information reporting and backup withholding. To avoid backup withholding, a U.S. Holder (as defined in Section 5 – “Material U.S. Federal Income Tax Consequences”) that does not otherwise establish an exemption from U.S. federal backup withholding must complete and return the Internal Revenue Service (“IRS”) Form W-9 included in the Letter of Transmittal. A non-U.S. Holder (as defined in Section 5 – “Material U.S. Federal Income Tax Consequences”) should submit an IRS Form W-8BEN or IRS Form W-8BEN-E (or other applicable IRS Form W-8) attesting to such non-U.S. Holder’s exempt foreign status in order to qualify for an exemption from information reporting and backup withholding (although other withholding of U.S. federal income tax may still apply). Non-U.S. Holders should consult their own tax advisors to determine which IRS Form W-8 is appropriate. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund from the IRS or a credit against a stockholder’s U.S. federal income tax liability, if any; provided the required information is timely furnished to the IRS.

4. Withdrawal Rights

Except as otherwise provided in this Section 4, or as provided by applicable law, tenders of Shares made pursuant to the Offer are irrevocable.

Shares tendered pursuant to the Offer may be withdrawn at any time prior to the Expiration Time. Thereafter, tenders are irrevocable, except that if we have not accepted your Shares for payment within 60 days after commencement of the Offer, you may withdraw them at any time after May 6, 2025, the 60th day after commencement of the Offer, until Merger Sub accepts your Shares for payment.

For a withdrawal of Shares to be effective, the Depositary must timely receive a written or facsimile transmission notice of withdrawal at one of its addresses set forth on the back cover of this Offer to Purchase. Any notice of withdrawal must specify the name of the person who tendered the Shares to be withdrawn, the number of Shares to be withdrawn and the names in which the Share Certificates are registered, if different from that of the person who tendered such Shares. The signature(s) on the notice of withdrawal must be guaranteed by an Eligible Institution unless such Shares have been tendered for the account of an Eligible Institution. If the Shares have been tendered pursuant to the procedures for book-entry transfer as set forth in Section 3 – “Procedures for Accepting the Offer and Tendering Shares,” any notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn Shares. If Share Certificates representing the Shares to be withdrawn have been delivered or otherwise identified to the Depositary, then, prior to the physical release of such Share Certificates, the name of the registered owners and the serial numbers shown on such Share Certificates must also be furnished to the Depositary.

Withdrawals of tenders of Shares may not be rescinded and any Shares validly withdrawn will be deemed not validly tendered for purposes of the Offer. Withdrawn Shares may, however, be re-tendered by following one of the procedures for tendering Shares described in Section 3 – “Procedures for Accepting the Offer and Tendering Shares” at any time prior to the Expiration Time.

We will determine, in our sole discretion, all questions as to the form and validity (including time of receipt) of any notice of withdrawal, and such determination will be final and binding, subject to any judgment of any court of competent jurisdiction. No withdrawal of Shares will be deemed to have been properly made until all defects and irregularities have been cured or waived. None of Parent, Merger Sub or any of their respective affiliates or assigns, the Depositary, the Information Agent or any other person will be under any duty to give notification of any defects or irregularities in any notice of withdrawal or incur any liability for failure to give such notification.

5. Material U.S. Federal Income Tax Consequences

The following is a discussion of the material U.S. federal income tax consequences of the Offer and the Merger to (i) U.S. Holders and Non-U.S. Holders (each as defined below) that tender their Shares, and whose tender of such Shares is accepted, in exchange for the Offer Price pursuant to the Offer and (ii) U.S. Holders and Non-U.S. Holders (each as defined below) whose Shares are converted into the right to receive the Merger Consideration pursuant to the Merger. This discussion is based on the Internal Revenue Code of 1986, as amended (the “Code”), U.S. Treasury Regulations promulgated thereunder, judicial interpretations thereof, and administrative rulings and published positions of the IRS, each in effect as of the date of this Offer to Purchase, and all of which are subject to change or differing interpretations, possibly with retroactive effect, and any such change or interpretation could affect the accuracy of the statements and conclusions set forth herein. We have not sought, and do not intend to seek, any ruling from the IRS or any opinion of counsel with respect to the statements made or the conclusions reached in the following summary. This discussion is not binding on the IRS or the courts, and no assurance can be given that the conclusions reached in this discussion will not be challenged by the IRS or that such challenge will not be sustained by a court.

This discussion applies to a holder of Shares only if the holder holds its Shares as a “capital asset” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion is for general information purposes only, does not constitute tax advice and does not address all aspects of U.S. federal income taxation that may be relevant to a holder of Shares in light of its particular circumstances, or that may apply to a holder subject to special rules under the U.S. federal income tax laws, including, but not limited to:

26

In addition, this discussion does not address the corporate or individual alternative minimum tax, the net investment income tax, any considerations with respect to any withholding required pursuant to the Foreign Account Tax Compliance Act of 2010 (including the Treasury Regulations promulgated thereunder and intergovernmental agreements entered in connection therewith and any laws, regulations or practices adopted in connection with any such agreement), any reporting requirements except to the extent expressly discussed below, or any tax considerations under state, local or non-U.S. laws or U.S. federal non-income tax laws (e.g., estate and gift tax).

If a partnership, or other entity or arrangement treated as a partnership for U.S. federal income tax purposes, or other pass-through entity for such purposes holds Shares, the tax treatment of its partners or members and such partnership or other pass-through entity generally will depend on the status of the partner or member and the activities of the partnership or other pass-through entity. Accordingly, partnerships and other pass-through entities for U.S. federal income tax purposes that hold Shares, and partners or members in those entities or arrangements, are urged to consult their own tax advisors regarding the specific U.S. federal income tax consequences to them of the Offer and the Merger.

This discussion of the material U.S. federal income tax consequences of the Offer and the Merger to holders of Shares is for general information only and is not, is not intended to be, and may not be construed as, legal or tax advice to holders of Shares. Because individual circumstances may differ, each holder of Shares is urged to consult his, her or its own tax advisors as to the applicability and effect of the rules discussed below and the particular tax consequences of the Offer and the Merger, including the applicability and effect of the corporate or individual alternative minimum tax and any U.S. federal, state, local and non-U.S. tax laws.

Tax Consequences to U.S. Holders

For purposes of this discussion, a “U.S. Holder” is any beneficial owner of Shares that, for U.S. federal income tax purposes, is (i) an individual who is a citizen or resident of the United States; (ii) a corporation (or any other entity or arrangement taxable as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia; (iii) an estate the income of which is subject to U.S. federal income tax regardless of its source; or (iv) a trust, if (A) a U.S. court is able to exercise primary supervision over the trust’s administration and one or more U.S. persons have authority to control all of the trust’s substantial decisions or (B) the trust has validly elected to be treated as a U.S. person for U.S. federal income tax purposes.

The exchange of Shares for the Offer Price pursuant to the Offer and the exchange of Shares for the Merger Consideration pursuant to the Merger will be a taxable transaction for U.S. federal income tax purposes.

The amount of gain or loss a U.S. Holder recognizes, and the timing and potential character of a portion of such gain or loss, depends on the U.S. federal income tax treatment of the CVRs, with respect to which there is a significant amount of uncertainty. The receipt of the CVRs pursuant to the Offer or the Merger might be treated as either a “closed transaction” or as an “open transaction” for U.S. federal income tax purposes, each as discussed in more detail below. The installment method of reporting any gain attributable to the receipt of or payments on the CVRs will not be available because the Shares are traded on an established securities market.

There is no legal authority expressly addressing whether the receipt of contingent payment rights with characteristics similar to the rights under the CVRs should be treated as an “open transaction” or a “closed transaction” for U.S. federal income tax purposes, and such determination is inherently factual in nature. Under

27

U.S. Treasury Regulations applicable to contingent payment obligations analogous to the CVRs, if the fair market value of the CVRs is “reasonably ascertainable,” the receipt of the Offer Price pursuant to the Offer and the receipt of the Merger Consideration pursuant to the Merger would be treated as a “closed transaction,” and a U.S. Holder would include the fair market value of the CVR as additional consideration received in the Offer or the Merger for purposes of determining gain or loss. On the other hand, if the fair market value of the CVRs cannot be reasonably ascertained, the transaction would be treated as an “open transaction.” These Treasury Regulations state that the value of contingent payment obligations will not be reasonably ascertainable only in “rare and extraordinary” cases. U.S. Holders are urged to consult their own tax advisors regarding the proper method of tax accounting with respect to the CVR and how to accurately report their income under the closed transaction method or open transaction method, as applicable in their respective case.

It is also possible that the CVRs may be treated as debt instruments for U.S. federal income tax purposes. However, as such treatment is unlikely, this discussion does not address the tax consequences of such a characterization and assumes that the CVRs are not treated as debt instruments for U.S. federal income tax purposes. We urge you to consult your tax advisor with respect to the proper characterization of a CVR and the receipt thereof.

Treatment as Closed Transaction. As noted above, if the value of the CVR is “reasonably ascertainable,” the transaction generally will be treated as a “closed transaction” for U.S. federal income tax purposes. If the receipt of a CVR is part of a closed transaction for U.S. federal income tax purposes, a U.S. Holder who sells or exchanges Shares pursuant to the Offer or the Merger generally will recognize capital gain or loss for U.S. federal income tax purposes in an amount equal to the difference, if any, between (i) the amount of cash received plus the fair market value (determined as of the closing of the Offer or the Effective Time, as the case may be) of the CVRs received and (ii) the U.S. Holder’s adjusted tax basis in the Shares sold or exchanged. No express guidance under current U.S. federal income tax law is available regarding the proper method for determining the fair market value of the CVRs. It is possible that the trading price of the Shares would be considered along with other factors. Any capital gain or loss recognized will be long-term capital gain or loss if the U.S. Holder’s holding period for such Shares exceeds one year. The deductibility of capital losses is subject to limitations. Gain or loss generally will be determined separately for each block of Shares (that is, Shares acquired at the same cost in a single transaction) exchanged pursuant to the Offer or the Merger.

If the transaction is treated as a “closed transaction” for U.S. federal income tax purposes, a U.S. holder’s initial tax basis in the CVR will equal the fair market value of the CVR on the date of the consummation of the Offer or the Merger, as applicable, and the holding period of the CVR will begin on the day following such date. There is no authority directly addressing the U.S. federal income tax treatment of receiving payments on the CVRs, and therefore, the character of any gain, income or loss recognized with respect to a payment on a CVR is uncertain. Such payments may be treated as payments with respect to a sale or exchange of a capital asset or as giving rise to ordinary income, including in part as imputed interest, as described more fully below. In addition, it is uncertain how a U.S. Holder of the CVRs would recover its adjusted tax basis in a CVR. Due to the legal and factual uncertainty regarding the valuation and tax treatment of the CVR, you are urged to consult your tax advisors concerning the recognition of gain, income or loss, if any, resulting from the receipt of the CVR and any payments with respect thereto.

Treatment as Open Transaction. As noted above, the exchange of Shares for the Offer Price pursuant to the Offer and the exchange of shares for the Merger Consideration pursuant to the Merger, as applicable, would generally be treated as an “open transaction” if the value of a CVR cannot be “reasonably ascertained.” Under U.S. Treasury Regulations relating to computation of gain or loss, the value of contingent payment rights is considered not to be reasonably ascertainable and, therefore, subject to the open transaction method, only in “rare and extraordinary” cases. If the receipt of a CVR pursuant to the Offer or the Merger is treated as an “open transaction” for U.S. federal income tax purposes, the fair market value of the CVR would not be treated as additional consideration for the Shares at the time the CVR is received, and the U.S. Holder will not have any tax basis in the CVR. Instead, the U.S. Holder will take payments under a CVR into account when made or deemed

28

made in accordance with the U.S. Holder’s regular method of accounting for U.S. federal income tax purposes. Generally, a portion of such payments will be treated as imputed interest, as described in more detail below, and the balance as additional consideration received in exchange for the Shares. Payments of cash pursuant to the Offer or the Merger, as applicable, and the portion of any payment on a CVR that is not treated as imputed interest will generally be applied first against a U.S. Holder’s adjusted tax basis in the Share with respect to which the CVR was received and any excess thereafter treated as capital gain. A U.S. Holder will recognize capital loss with respect to a Share to the extent that the holder’s adjusted tax basis in such Share exceeds the payments of cash pursuant to the Offer or the Merger, as applicable, plus the payment (other than imputed interest), if any, in respect of the CVR, and a U.S. Holder may not be able to recognize such loss until the resolution of all contingencies under the CVR. Any such capital gain or loss will be long-term capital gain or loss if the U.S. Holders’ holding period in the Share exceeds one year. The deductibility of capital losses is subject to limitations. Gain or loss generally will be determined separately for each block of Shares (that is, Shares acquired at the same cost in a single transaction) exchanged pursuant to the Offer or the Merger.

Imputed Interest. If any payment with respect to a CVR is made more than six months after the closing of the Offer or the Effective Time (as applicable), a portion of the payment may be treated as imputed interest that is ordinary income to a U.S. Holder under Section 483 of the Code. The portion of any payment made with respect to a CVR treated as imputed interest will be determined at the time such payment is made and generally should equal the excess of (i) the amount of the payment in respect of the CVR over (ii) the present value of such amount as of the closing of the Offer or the Effective Time, as the case may be, calculated using the applicable federal rate as the discount rate. A U.S. Holder must include the imputed interest in its taxable income using such stockholder’s regular method of accounting for U.S. federal income tax purposes.

Tax Consequences to Non-U.S. Holders

For purposes of this discussion, a “Non-U.S. Holder” is any beneficial owner of Shares that is not a partnership (or other entity or arrangement treated as a partnership) for U.S. federal income tax purposes and that is not a U.S. Holder.

Any gain realized by a Non-U.S. Holder upon the exchange of Shares pursuant to the Offer or the Merger, as the case may be, generally will not be subject to U.S. federal income or withholding tax unless (i) the gain is effectively connected with a U.S. trade or business of such Non-U.S. Holder (and, if an applicable treaty so provides, is also attributable to a permanent establishment maintained by such Non-U.S. Holder in the United States), in which case the Non-U.S. Holder generally will be taxed in the same manner as a U.S. Holder (as described above under “Tax Consequences to U.S. Holders”), except that if the Non-U.S. Holder is a foreign corporation, an additional branch profits tax may apply at a rate of 30% (or a lower applicable treaty rate), (ii) the Non-U.S. Holder is a nonresident alien individual who is present in the United States for 183 days or more in the taxable year of the closing of the Offer or the Effective Time, as the case may be, and certain other conditions are met, in which case the Non-U.S. Holder may be subject to a 30% U.S. federal income tax (or a tax at a reduced rate under an applicable income tax treaty) on such gain (net of certain U.S. source losses), or (iii) the Company is or has been a United States real property holding corporation within the meaning of the Section 897(c)(2) of the Code for U.S. federal income tax purposes and such Non-U.S. Holder owned, directly or indirectly, at any time during the five-year period ending on the date of the distribution, more than 5% of the Shares and such Non-U.S. Holder is not eligible for any treaty exemption, in which case the Non-U.S. Holder generally will be subject to U.S. federal income tax on the disposition of Shares in the same manner as a U.S. Holder.

Generally, if payments are made to a Non-U.S. Holder with respect to a CVR, such Non-U.S. Holder may be subject to withholding at a rate of 30% (or a lower applicable treaty rate) of the portion of any such payments treated as imputed interest (as discussed above under “Tax Consequences to U.S. Holders – Imputed Interest”), or possibly the entire CVR payment depending on the U.S. federal income tax treatment thereof, unless such Non-U.S. Holder establishes its entitlement to exemption from or a reduced rate of withholding under an applicable tax treaty by providing the appropriate documentation (generally, IRS Form W-8BEN or W-8BEN-E or other applicable IRS Form W-8) to the applicable withholding agents.

29

Information Reporting and Backup Withholding

Information reporting generally will apply to payments to a stockholder pursuant to the Offer or the Merger, unless such stockholder is an entity that is exempt from information reporting and, when required, properly demonstrates its eligibility for exemption. In addition, payments with respect to the CVRs may be subject to information reporting and backup withholding. Tax information provided to a U.S. Holder and the IRS on IRS Form 1099-B for the year of the Offer or the Merger, as applicable, may reflect only the payments of cash made pursuant to the Offer or the Merger, as applicable, and not the fair market value of the CVRs. Accordingly, a U.S. Holder that treats the Offer or the Merger as a “closed transaction” for U.S. federal income tax purposes may receive an IRS Form 1099-B reporting an amount that is less than the amount such U.S. Holder will realize in the year of the Offer or the Merger, as applicable. In addition, any IRS Form 1099-B that a U.S. Holder receives with respect to payments on the CVRs may reflect the entire amount of the CVR payments made to the U.S. Holder (other than imputed interest) and therefore may not take into account the fact that the U.S. Holder already included the value of such payments in such U.S. Holder’s amount realized in the year of the Offer or the Merger, as applicable. As a result, U.S. Holders reporting under the “closed transaction” method should not necessarily rely on the amounts reported to them on IRS Forms 1099-B with respect to the Offer or the Merger, as applicable. U.S. Holders are urged to consult their tax advisors regarding how to accurately report their income under the “closed transaction” method. On the other hand, tax information provided to a U.S. Holder and the IRS on IRS Form 1099-B for the year of the Offer or the Merger, as applicable, may reflect both the payments of cash made pursuant to the Offer or the Merger, as applicable, and the fair market value of the CVRs. U.S. Holders that treat the Offer or the Merger, as applicable, as an “open transaction” for U.S. federal income tax purposes are urged to consult their own tax advisors regarding how to accurately report their income under this method.

Any payment to a U.S. Holder that is subject to information reporting generally will also be subject to backup withholding, unless such U.S. Holder provides the appropriate documentation (generally, an IRS Form W-9) to the applicable withholding agent certifying that, among other things, its taxpayer identification number is correct, or otherwise establishes an exemption.

The backup withholding rules that apply to payments to a stockholder pursuant to the Offer and Merger generally will not apply to payments to a Non-U.S. Holder if such Non-U.S. Holder certifies under penalties of perjury that it is not a U.S. person (generally by providing an IRS Form W-8BEN or W-8BEN-E or other applicable IRS Form W-8) or otherwise establishes an exemption. Non-U.S. Holders should consult their own tax advisors to determine which IRS Form W-8 is appropriate. However, as noted above, payments to Non-U.S. Holders may be subject to U.S. federal income tax withholding other than backup withholding.

Backup withholding is not an additional tax and the amount of any backup withholding will be generally allowed as a credit against a U.S. Holder’s U.S. federal income tax liability and may entitle such holder to a refund, provided that the required information is properly and timely furnished by such U.S. Holder to the IRS.

U.S. Holders should consult their own tax advisors to determine their qualification for exemption from backup withholding and the procedure for obtaining such exemption.

9. Source and Amount of Funds

We estimate that we will need approximately $29.9 million to purchase all of the Shares pursuant to the Offer or the Merger and to make payments in respect of outstanding Company RSUs, Company PSUs and other payments referred to in the Merger Agreement required to be made in connection with the consummation of the Merger (the “Closing”) pursuant to the Merger Agreement. Parent expects to fund the cash requirements for the Transactions through committed equity financing (the “Financing”) necessary to satisfy all of Merger Sub’s payment obligations under the Merger Agreement and resulting from the Offer.

As of the date of the Merger Agreement, Parent has received the Equity Commitment Letters from the Guarantors, pursuant to which the Guarantors have collectively committed, subject to the terms of the Equity Commitment Letters and in accordance with the Merger Agreement, to provide an aggregate equity financing up to the lesser of (i) $31.0 million or (ii) an amount solely for the purpose of funding, and to the extent necessary to fund, (a) the payment of the aggregate Offer Price and the aggregate Merger Consideration in accordance with the Merger Agreement and (b) the payment of all related fees and expenses required to be paid by Parent or Merger Sub at or in connection with the Acceptance Time or the Closing pursuant to and in accordance with the Merger Agreement to Parent for the purpose of enabling Parent to fund amounts required to be paid pursuant to the Merger Agreement, subject to the satisfaction of certain customary conditions set forth in the Equity Commitment Letters (collectively, the “Equity Commitment Amount”).

The conditions to the Guarantors’ obligation to fund the Equity Commitment Amount under the respective Equity Commitment Letters include: (a) with respect to the Offer Price, (i) the valid execution and delivery of the Merger Agreement by the Company, (ii) the satisfaction in full or valid waiver, in accordance with the Merger Agreement, of all of the Offer Conditions, (iii) the contemporaneous occurrence of the Acceptance Time, and (iv) the earlier or substantially concurrent receipt by Parent of the Carlyle Guarantors’ commitment (in the case of the SK Capital Equity Commitment Letter) or the SK Capital Guarantors’ commitment (in the case of the Carlyle Equity Commitment Letter) in respect thereof pursuant to the respective Equity Commitment Letters, and (b) with respect to the Merger Consideration, (i) the valid execution and delivery of the Merger Agreement by the Company, (ii) the satisfaction in full or valid waiver on or before the Closing, in accordance with the Merger Agreement, of all of the conditions to the Merger set forth in Article VIII of the Merger Agreement, (iii) the substantially contemporaneous consummation of the Closing, and (iv) the earlier or substantially concurrent receipt by Parent of the Carlyle Guarantors’ commitment (in the case of the SK Capital Equity Commitment Letter) or the SK Capital Guarantors’ commitment (in the case of the Carlyle Equity Commitment Letter) in respect thereof pursuant to the respective Equity Commitment Letters.

Upon termination of the Equity Commitment Letters, the Guarantors have no further obligations with respect thereto. All obligations of the Guarantors under the Equity Commitment Letters shall expire automatically and immediately upon the earliest to occur of (a) the valid termination of the Merger Agreement pursuant to Article IX of the Merger Agreement, (b) the date that (x) the Company, (y) any controlled affiliate of the Company or any of their respective managers, directors or officers, or (z) any other member of the Company Group (as defined in the Equity Commitment Letters) acting at the direction or at the request of any of the foregoing, asserts in any litigation or other proceeding (A) that one or more of the provisions of the Equity Commitment Letters are illegal, invalid or unenforceable in whole or in part, or that the Guarantors have any liability under the Equity Commitment Letters other than to fund to Parent equity contributions with respect to the Equity Commitment Amount in an aggregate amount not to exceed their respective Commitment Cap (as defined in the respective Equity Commitment Letters), in accordance with the terms and subject to the conditions hereof, solely to the extent an order of specific performance is granted to the Company pursuant to the Merger Agreement or (B) any other claim or theory of liability against the Guarantors or the Non-Recourse Parties (as defined in the Equity Commitment Letters) relating to the Equity Commitment Letters, the Merger Agreement, the Limited Guarantees (as defined herein), the Confidentiality Agreement (as defined herein) or any of the transactions contemplated thereby (including in respect of any oral representations made or alleged to be made in connection herewith or therewith), other than a Retained Claim (as defined in the Limited Guarantees), or any

34

Retained Claim other than in the courts described in the definition thereof, (c) the Guarantors and any assignees of the Guarantors, collectively, contributing to Parent cash in an aggregate amount equal to or exceeding their respective Commitment Cap, (d) the payment of the Payment Obligations (as defined in the Limited Guarantees) when required to be paid pursuant to the Limited Guarantees or pursuant to the Merger Agreement, (e) the occurrence of the Closing, (f) the occurrence of any event that, by the terms of the Limited Guarantees, is an event that terminates or gives right to terminate the Guarantors’ obligations or liabilities under the Limited Guarantees, (g) in the case of the Carlyle Equity Commitment Letter, the occurrence of any event, other than as set forth in the SK Capital Equity Commitment Letter, that, by the terms of the SK Capital Equity Commitment Letter, is an event that terminates or gives right to terminate the SK Capital Guarantors’ obligations or liabilities under the SK Capital Equity Commitment Letter, or in the case of the SK Capital Equity Commitment Letter, the occurrence of any event, other than as set forth in the Carlyle Equity Commitment Letter, that, by the terms of the Carlyle Equity Commitment Letter, is an event that terminates or gives right to terminate the Carlyle Guarantors’ obligations or liabilities under the Carlyle Equity Commitment Letter, (h) if a court of competent jurisdiction has declined in a final, non-appealable decision, judgment or order to specifically enforce the obligations of Parent and/or Merger Sub to consummate the Offer and/or the Merger pursuant to a claim for specific performance brought against Parent and/or Merger Sub pursuant to the Merger Agreement or the obligations of the Guarantors to fund the commitment under the Equity Commitment Letters and (i) any proceeding being instituted by or against the Company (and in the case of a proceeding initiated against the Company, which has not been dismissed within 30 days), seeking to adjudicate it as bankrupt or insolvent, or seeking receivership, interim receivership, liquidation, winding up, reorganization, arrangement, adjustment, protection, relief, or composition of it or its debts under any debtor relief law. Upon termination of the Equity Commitment Letters, the obligations and liabilities of the Guarantors and their assignees shall become null and void ab initio and of no further force and effect.

This summary does not purport to be complete and is qualified in its entirety by reference to the full text of the Carlyle Equity Commitment Letter and the SK Capital Equity Commitment Letter, copies of which have been filed as Exhibit (d)(5) and Exhibit (d)(7), respectively to the Schedule TO and which is incorporated herein by reference.

Parent expects, based upon the Financing, to have sufficient cash on hand at the Expiration Time to advance or otherwise contribute funds to Merger Sub to allow it to consummate the Merger (including payments for, Company RSUs, Company PSUs and other payments referred to in the Merger Agreement) pursuant to the Merger Agreement and to purchase all of the Shares pursuant to the Offer and the Merger Agreement. The Offer is not conditioned upon Parent’s or Merger Sub’s ability to finance the purchase of the Shares pursuant to the Offer.

10. Background of the Offer; Past Contacts or Negotiations with the Company

Background of the Offer and the Merger

The following chronology summarizes the key meetings and events between representatives of Parent, Merger Sub, Carlyle, SK Capital and PJ Carlin & Co. LLC (“PJC”), on one hand, and representatives of the Company and Hercules, on the other hand, that led to the signing of the Merger Agreement. The following chronology does not purport to catalogue every conversation among representatives of Parent, Merger Sub and the Company. For a review of the Company’s additional key activities that led to the signing of the Merger Agreement, please refer to the section entitled “Item 4. The Solicitation or Recommendation—Background and Reasons for the Company Board’s Recommendation—Background of the Offer and the Merger” in the Schedule 14D-9.

On November 13, 2024, representatives of Company management met with David Meek of PJC. Mr. Meek recommended that the Company enter into a confidentiality agreement with PJC to evaluate a potential take-private investment opportunity. On November 14, 2024, the Company executed a confidentiality agreement with PJC, which did not contain a standstill provision.

35

Following discussions with the Company, on November 24, 2024, PJC delivered an initial term sheet (“Proposal 1”) to the Company, offering to acquire the Company at a price of $100 million in upfront cash, plus a $60 million CVR payable if the Company’s current commercial product portfolio achieved a milestone of $600 million in net sales in one calendar year, so long as it occurred no later than four years from the closing date. Proposal 1 also included certain conditions to closing relating to the effectiveness of employment agreements and non-competition agreements for key employees, and receipt of certain third party consents deemed necessary by PJC, and approval by the Company’s third-party lenders. Proposal 1 also included an exclusivity provision through December 31, 2024 and a provision requiring the stockholders of the Company to indemnify PJC, its directors and officers, stockholders, lenders, affiliates and other representatives in certain circumstances. At the close of market on November 25, 2024, the next trading day thereafter, the Company’s stock price was $7.23 (adjusted to give effect to the Company’s subsequent 1-for-20 reverse stock split), down over 75% from the beginning of 2024.

On November 25, 2024, representatives of Leerink Partners LLC (“Leerink Partners”) spoke with representatives of PJC to clarify certain elements of Proposal 1, including the terms of the upfront and contingent consideration, how PJC intended to treat the Company’s outstanding debt and the source of capital to fund the proposed transaction. Representatives of PJC confirmed the terms of the proposed upfront and contingent consideration, that the treatment of the Company’s outstanding debt remained under consideration and that PJC was engaged in discussions with potential sources of capital (including various financial sponsors) but had not yet secured committed financing.

Between December 2 and December 19, 2024, Company management and representatives of PJC conducted business-level diligence meetings related to the Company’s operations and commercial matters, including PJC receiving management presentations from Company management from December 3 to December 5, 2024. Following meetings with Company management, PJC engaged in further discussions with the Company regarding a potential acquisition of the Company.

On December 4, 2024, Leerink Partners reached out to PJC requesting PJC resubmit their proposal with revised terms to reflect the consideration on a per share basis, clarify the proposed treatment of the Company’s outstanding debt, identify PJC’s source of financing, limit conditions to closing and remove the Company indemnity. Later that day, PJC indicated that they would consider revising their proposal in light of the Company’s requests.

On December 10, 2024, a member of the Company Board discussed with PJC its intention to submit a revised proposal, which would specify the consideration on a per-share basis and include details about its financing source. PJC also indicated that an affiliate of Carlyle could provide the committed financing for PJC’s proposal.

On December 14, 2024, PJC delivered a revised term sheet (“Proposal 2”) to the Company, offering to acquire the Company at a price of $10.00 per share in upfront cash, plus a $6.00 per share CVR payable if the Company’s then current commercial product portfolio achieved a milestone of $700 million in net sales in one calendar year prior to December 31, 2029. Proposal 2 retained certain conditions to closing, including with respect to the effectiveness of employment agreements and non-competition agreements for certain employees. Proposal 2 omitted closing conditions for receipt of any third party consents deemed necessary by PJC as well as approval by the Company’s third-party lenders and did not include the Company indemnification provision from Proposal 1. Proposal 2 included an exclusivity provision applicable to the Company and stockholders in the Company through January 17, 2025.

On December 15, 2024, representatives of Leerink Partners engaged in discussions with representatives from PJC to clarify certain elements of PJC’s revised proposal, particularly regarding closing conditions and covenants. Later that week, on December 17, 2024, representatives from PJC, Carlyle and Hercules Capital, Inc., the Company’s secured lender (“Hercules”), met to discuss a range of alternatives for the treatment of the Company’s loan and security agreement, as amended (the “LSA”), with Hercules.

On December 18, 2024, representatives of Leerink Partners reached out to PJC to request the removal of certain closing conditions and covenants from Proposal 2.

That weekend, PJC sent a revised term sheet (“Proposal 3”) to the Company, offering substantially the same terms as Proposal 2 except for a revised exclusivity provision through January 17, 2025 that was applicable only to the Company.

On December 24, 2024, representatives of the Company sent a revised version of Proposal 3 to PJC, including revisions (A) removing certain closing conditions with respect to employee matters and (B) granting exclusivity through January 10, 2025, with an express carveout to exclusivity for (1) sales of securities for fundraising purposes and (2) sales of assets or businesses in connection with a bankruptcy process. Along with the revised version of Proposal 3, representatives of the Company also provided to PJC an initial draft Merger Agreement which provided for, among other things, PJC to acquire the Company via a tender offer, PJC’s obligation to do everything necessary to obtain antitrust clearances and a customary “fiduciary out” enabling the Company Board to entertain and accept potential alternative, unsolicited offers following entry into the Merger Agreement, subject to the Company’s payment of a market standard termination fee in connection therewith.

On December 27, 2024, representatives of PJC called representatives of Leerink Partners to inform them that, following further due diligence of financial statements and projections for fiscal year 2024 provided by the Company to PJC, which included an update on the Company’s current and projected deferred accounts payable, PJC intended to submit a revised proposal reflecting a reduced valuation. On December 30, 2024, PJC delivered a revised proposal (“Proposal 4”), offering to acquire the Company at a reduced price of $3.00 per share in upfront cash, plus a $6.00 per share CVR payable if the Company’s current commercial product portfolio achieved a milestone of $600 million in net sales in one calendar year, so long as it occurred no later than December 31, 2027. In Proposal 4, PJC also accepted the Company’s proposed deletion of the employee-related closing conditions and provided for exclusivity applicable to the Company through January 10, 2025 with an extension to January 31, 2025 upon the delivery by PJC of a financial commitment letter from PJC’s financial sponsor on or prior to January 10, 2025. Throughout this exclusivity period, the Company would also be permitted to engage with third parties in connection with (A) sales of securities for fundraising purposes and (B) sales of assets or businesses in connection with a bankruptcy process, provided that the Company was restricted from signing an agreement in connection therewith through the agreed to termination date, as may be extended pursuant to the terms of the agreement. At the close of market on December 30, 2024, the Company’s stock price was $7.86, down approximately 75% from the start of 2024.

On December 31, 2024, representatives of Leerink Partners initiated discussions with PJC regarding the justifications for the reduced price, which such discussions occurred over the following days. On January 3, 2025, representatives from Leerink Partners responded to PJC regarding PJC’s revised proposal, proposing $6.00 per share in upfront cash, plus an $8.00 per share CVR payable upon the achievement of $500 million in net sales in any trailing twelve month period prior to December 31, 2028, and exclusivity applicable to the Company through January 17, 2025.

On January 4, 2025, representatives from PJC contacted Leerink Partners to convey that they did not intend to modify their proposal, except for changing the measurement period for the CVR payment from a calendar year to a trailing twelve months.

On January 5, 2025, a member of the Company Board communicated to PJC the position that PJC’s offer should be revised to increase the consideration payable to Company stockholders and that without increased consideration, the Company was hesitant to proceed with exclusive negotiations.

On January 6, 2025, a representative of PJC contacted a member of the Company Board and indicated that PJC would improve upon its Proposal 4 by increasing the CVR payment from $6.00 per share to $7.00 per share and would add a $9.00 CVR payable in the event the Company received a certain priority review voucher

37

(“PRV”) from the U.S. Food and Drug Administration (the “FDA”) within 90 days of the closing of the proposed acquisition. PJC noted this proposal was its “best and final” offer. Later that day, PJC delivered a revised term sheet (“Proposal 5”) to Company management, offering to acquire the Company at a price of $3.00 per share in upfront cash, with two CVRs payable: (A) $7.00 per share if the Company’s current commercial product portfolio achieved a milestone of $600 million in net sales in one calendar year prior to December 31, 2027 and (B) $9.00 per share in the event the Company received the PRV within 90 days of the closing of the proposed transaction. In Proposal 5, PJC also proposed exclusivity applicable to the Company through January 27, 2025.

On January 7, 2025, a representative of Leerink Partners, on behalf of the Company, delivered an executed term sheet to PJC which provided that the Company would enter into a period of exclusive negotiations with PJC on the following conditions: (A) the CVR measurement period would be calculated based on a trailing twelve month period rather than a calendar year; and (B) exclusivity would terminate on January 17, 2025, provided that if on such date, the Company and PJC were negotiating in good faith to complete the transaction, exclusivity would be automatically extended through January 24, 2025. Throughout the exclusivity period, the Company would also be permitted to engage with third parties in connection with (i) sales of securities for fundraising purposes and (ii) sales of assets or businesses in connection with a bankruptcy process, provided that the Company was restricted from signing an agreement in connection therewith through the agreed to termination date, as may be extended pursuant to the terms of the agreement. The revised term sheet was countersigned by PJC later that day.

On January 8, 2025, representatives of Latham & Watkins LLP (“Latham”) and representatives of Orrick, Herrington & Sutcliffe LLP (“Orrick”), outside counsel to PJC and its equity investors, met and discussed the terms of the transaction and process to reach alignment on a definitive agreement by January 17, 2025, and on January 9, 2025, the Company granted access to its data room to Orrick.

On January 10, 2025, representatives from PJC delivered a commitment letter from Carlyle to Company management which outlined the terms and conditions under which Carlyle would provide the necessary funding for the proposed transaction contemplated by the executed term sheet. That same day, representatives from Latham shared the initial draft of the CVR Agreement with Orrick.

On January 13, 2025, Hercules sent the initial draft of the consent and fifth amendment to the LSA (the “Fifth LSA Amendment”) to the Company. Among other things, the proposed Fifth LSA Amendment set forth new levels for the minimum cash covenant from the existing LSA, depending on the Company’s ability to transfer an existing letter of credit in connection with one of its leases, and included a consent to such transfer. The draft also required the Company to deliver a rolling 13 week cash flow forecast to Hercules each week and added a new event of default, which would be triggered if (i) the Company failed to enter into a merger agreement with a third party, in form and in substance acceptable to Hercules, by a date certain (an “Acceptable Merger Agreement”), (ii) if, after entry into an Acceptable Merger Agreement, such agreement was either terminated or amended in a manner unacceptable to Hercules or (iii) the transactions contemplated by the Acceptable Merger Agreement were not consummated on or prior to a date certain. That same day, the Company was notified by the FDA that its application in connection with a priority review voucher for the Company’s product LYFGENIA was denied.

On January 14, 2025, representatives of Orrick connected Latham with representatives of Wachtell, Lipton, Rosen & Katz (“WLRK”), outside counsel to Carlyle, and on the following day, representatives of Latham shared an initial draft of the Company Disclosure Letter with representatives of Orrick and WLRK. On January 17, 2025, representatives of Orrick sent to Latham supplemental diligence requests based on their initial diligence and from the middle of January through February 20, 2025, the Company held numerous calls with PJC, Carlyle and their respective advisors regarding various customary legal diligence topics, including regulatory matters, employment, tax, litigation, operations and intellectual property.

On January 18, 2025, Orrick sent revised drafts of the Merger Agreement and CVR Agreement to Latham. The revised draft Merger Agreement, among other things, included a closing condition regarding the minimum

38

amounts of cash and maximum amounts of indebtedness and accounts payable to be held by the Company at Closing, included an uncapped expense reimbursement by the Company to PJC in the event the Merger Agreement was terminated in certain instances, proposed a termination fee payable by the Company in certain instances of $4 million and included an outside date of six months after the signing of the Merger Agreement, and the revised draft CVR Agreement, among other things, reflected removal of the milestone related to achievement of the PRV. That same day, the initial draft of the conformed LSA (the “Post-Closing LSA”), reflecting the anticipated terms to go into effect at the closing of the merger transaction, was sent from DLA Piper LLP (“DLA”), counsel to Hercules, to Latham and Orrick.

On January 21, 2025, DLA shared the initial draft of the proposed sixth amendment to the LSA (the “Sixth LSA Amendment” and, together with the Fifth LSA Amendment and the Post-Closing LSA, the “Debt Documents”) with representatives of Latham, WLRK, and Orrick. Pursuant to the proposed terms of the Sixth LSA Amendment, Hercules would, among other things: (A) consent to the Company’s entry into the Merger Agreement and the consummation of the Merger and (B) agree to, upon satisfaction of certain conditions therein (including the consummation of the merger), amend certain terms of the existing LSA (as amended by the Fifth LSA Amendment), as set forth therein. In addition, Hercules would acknowledge that the warrants previously issued to Hercules in connection with the existing LSA would be cancelled and extinguished for no consideration at the effective time of the Merger in accordance with the terms of such warrants.

On January 22, 2025, representatives of Latham sent revised drafts of the Merger Agreement and CVR Agreement to Orrick, which drafts included revisions, with respect to the Merger Agreement, removing the closing conditions relating to the Company’s accounts payable, indebtedness and cash on hand, each at closing, and reducing the proposed expense reimbursement to $300,000 and Company termination fee to $1.5 million, as well as certain other revisions throughout the representations, warranties and covenants and, in the CVR Agreement, allowing stockholders to audit and dispute the net sales calculations and to include the indirect sale of the Company’s products by PJC in the net sales metrics. That same day, Hercules sent revisions to the proposed Fifth LSA Amendment to the Company, which, among other things, (A) provided for a 24-hour grace period from any breaches of the minimum cash covenant while Hercules and the Company use good faith efforts to discuss the Company’s return to compliance, (B) proposed increases for certain of the levels set forth in the minimum cash covenant, and (C) proposed that the Company and its successors indemnify Hercules for all tax liabilities or losses suffered by Hercules as a result of the merger transactions.

From January 22, 2025 through February 20, 2025, representatives of Latham, Orrick and WLRK negotiated the Company Disclosure Letter and CVR Agreement and representatives of Orrick, WLRK, Latham and DLA negotiated the terms of the Debt Documents.

On January 24, 2025, PJC shared a draft exclusivity extension letter with the Company, proposing to extend exclusivity through February 7, 2025 and, if the Company and PJC continued to negotiate in good faith, exclusivity would automatically be extended for successive one-week periods until either party chose to terminate exclusivity.

On January 25, 2025, the initial exclusivity term in the executed letter of intent terminated and was not extended by the parties.

On January 26, 2025, representatives of Orrick shared a revised Merger Agreement draft, which, among other things, reinserted certain conditions to closing the transaction, including with respect to the Company’s accounts payable, indebtedness and cash on hand, each at closing, added representations and warranties of the Company relating to the Hercules loan agreement amendments, increased the amounts contemplated to be paid by the Company to PJC in connection with the proposed expense reimbursement and termination fees to $4 million each, capped the Company’s right to seek monetary damages at $10 million, and proposed an outside date of May 30, 2025.

Among other things, the draft made certain revisions to the representations and warranties of the Company related to the Debt Documents, removed the closing conditions related to minimum cash and maximum indebtedness and accounts payable, revised the proposed outside date to April 4, 2025, reduced the termination fee payable by the Company to PJC in certain instances to $1.5 million, reduced the expense reimbursement payable by the Company to PJC in certain instances to $300,000, and increased the cap in monetary damages the Company could seek to $30 million.

On January 31, 2025, representatives of Latham and Orrick met to discuss the transaction and representatives of Orrick noted that they had no substantive updates on timing for the signing of the transaction. That same day, representatives of WLRK shared initial drafts of the Carlyle Equity Commitment Letter and the Carlyle Limited Guarantee with representatives of Latham. From January 31, 2025 through February 20, 2025, representatives of Latham and representatives of WLRK negotiated the Carlyle Equity Commitment Letter and Carlyle Limited Guarantee.

On February 1, 2025, representatives of Orrick shared a revised draft of the Merger Agreement with Latham. Among other things, the draft contemplated an amendment to the Company’s factoring agreement as a condition to signing the Merger Agreement, noted the termination fee and expense reimbursement payable by the Company as open points, reverted the cap in monetary damages payable to the Company to $10 million and proposed an outside date for the transaction of 75 days from signing of the Merger Agreement. That same day, representatives of DLA shared a revised draft of the Fifth LSA Amendment, which, among other things, gave Hercules the right to verify any accounts which the Company designated as excluded from the requirement to obtain a control agreement in favor of Hercules and made certain revisions to the minimum cash covenant levels and the triggers for an event of default relating to the consummation of the Merger Agreement.

On February 2, 2025, representatives of Latham shared a revised draft of the Merger Agreement with Orrick and WLRK, contemplating removal of the proposed amendment to the Company’s factoring agreement, a termination fee payable by the Company to PJC of $1.5 million, an expense reimbursement amount payable by the Company to PJC of $300,000, a proposed outside date of April 11, 2025 and acceptance of PJC’s cap for monetary damages of $10 million, provided that PJC accepted the Company’s other revisions. The Company also discussed these open points with PJC and indicated that this was the Company’s proposed package to resolve the open business terms.

On February 4, 2025, representatives of Orrick, Latham and WLRK met to discuss the open issues in the Merger Agreement draft, and the following day, representatives of the Company discussed the transaction with each of PJC and Carlyle. During these conversations, representatives of Carlyle notified the Company that it would need until sometime the following week to obtain the internal approvals required to finance the transaction.

On February 7, 2025, representatives of Orrick shared a revised draft of the Merger Agreement with Latham, which revised draft included an outside date of 65 days after signing, buyer-favorable changes to certain representations and warranties of the Company related to the Debt Documents and an indemnity payable by the Company to Parent in certain circumstances.

Representatives of Latham met with representatives of Orrick and WLRK on February 9, 2025, to discuss the key open issues in the Merger Agreement and on February 10, 2025, representatives of Latham shared a revised draft of the Merger Agreement with Orrick and WLRK, contemplating an outside date of April 11, 2025 and rejecting the indemnity proposal.

On February 13, 2025, representatives of Carlyle informed a representative of Leerink Partners that Carlyle needed several more days to secure the funds required to finance the transaction. The Company noted that same day that it was unwilling to continue expending resources on pursuing a transaction unless it could be signed

40

expediently. Also on February 13, 2025, Carlyle began engaging with SK Capital regarding SK Capital’s potential participation as an additional financing partner to Carlyle.

On February 17, 2025, PJC reached out to the Company with a letter from Carlyle and SK Capital, reaffirming PJC’s interest in the transaction, indicating that SK Capital would be participating as an additional financing partner to Carlyle, and noting that with the inclusion of SK Capital, PJC was ready to proceed to a signing as soon as the parties agreed to terms for the transaction agreements. That evening, representatives of Latham, Orrick, WLRK and Kirkland & Ellis LLP (“K&E”), outside counsel to SK Capital, met and discussed updates to the transaction structure, including that certain regulatory filings would now be required to be obtained in non-US jurisdictions prior to the closing of the transaction.

Over the course of the next three days, the parties turned revised drafts of the Merger Agreement and the related ancillary documents. On February 18, 2025, representatives of WLRK shared a revised draft of the Merger Agreement with Latham, which revised draft included certain edits to reflect the additional involvement of SK Capital, a requirement to obtain specified foreign regulatory filings and revisions to certain representations and warranties of the Company related to the Debt Documents, and noted that the outside date remained subject to further discussion. In addition, revised drafts of the Carlyle Equity Commitment Letter and Carlyle Limited Guarantee were shared along with a draft of the SK Capital Equity Commitment Letter and a draft of the SK Capital Limited Guarantee from SK Capital.

On February 19, 2025, Leerink Partners communicated to PJC that the Company would not accept an outside date beyond April 18, 2025. In response, PJC proposed that the outside date for the transaction would be set at April 30, 2025 and would automatically extend for four weeks on up to 3 occasions if regulatory approvals were not obtained by the outside date, including as extended, with a reverse termination fee of $1 million payable if the transaction was terminated after the first outside date extension, a reverse termination fee of $2 million payable if the transaction was terminated after the second outside date extension and a reverse termination fee of $3 million payable if the transaction was terminated after the final outside date extension. PJC proposed that such reverse termination fee would reduce dollar for dollar the minimum cash thresholds in the Fifth LSA Amendment during the interim period and could be increased by Parent in its sole discretion.

On February 20, 2025, there were multiple all hands calls with representatives of Company management, Latham, Leerink Partners, PJC, Orrick, Carlyle, WLRK, SK Capital, K&E, Hercules and DLA to discuss and align on the remaining open points in the transaction documentation, including: the proposed outside date; the amount and triggers for the reverse termination fee payable by Parent to the Company; and the minimum cash condition levels, related triggers and the requirements for what triggers an event of default relating to the Merger Agreement in the Fifth LSA Amendment and Sixth LSA Amendment. Upon completion of the final all hands call, the parties agreed upon an outside date of April 25, 2025, a reverse termination fee concept by which the outside date for the transaction would automatically extend in certain instances for four-weeks on two occasions, with a reverse termination fee of $1 million payable if the transaction was terminated after the first outside date extension and a reverse termination fee of $2 million payable if the transaction was terminated after the second outside date extension, with such termination fees payable directly to Hercules and to reduce dollar for dollar the minimum cash thresholds in the Fifth LSA Amendment during the interim period and subject to increase by Parent in its sole discretion, and aligned on the appropriate minimum cash conditions and termination triggers in the Fifth LSA Amendment and Sixth LSA Amendment.

That same night and into early the next morning on February 21, 2025, the parties finalized the execution versions of the transaction documents, and the Company, PJC, Merger Sub, Parent, Carlyle, SK Capital and Hercules, as applicable, executed and delivered the Merger Agreement (which included as an exhibit the form of the CVR Agreement and the Company Disclosure Letter as annexes or schedules thereto), the Carlyle Equity Commitment Letter, the Carlyle Limited Guarantee, the SK Capital Equity Commitment Letter, the SK Capital Limited Guarantee and the Debt Documents. Later that morning, before the opening of the markets in the United States, the Company, Carlyle and SK Capital issued a joint press release announcing the execution and delivery of the Merger Agreement and the other transaction documents.

11. The Merger Agreement; Other Agreements

The following are summaries of the material terms of the Merger Agreement, the CVR Agreement, the Confidentiality Agreement and the Limited Guarantees. They have been included to provide investors and stockholders with information regarding the terms of such agreements. The following descriptions are summaries and are qualified by reference to the definitive agreements themselves, which have been filed as exhibits to the Schedule TO. Company stockholders and other interested parties should read the Merger Agreement, the CVR Agreement, the Confidentiality Agreement and the Limited Guarantees in their entirety for more complete descriptions of the terms summarized below. The Merger Agreement may be examined and copies may be obtained at the places and in the manner set forth in Section 8 – “Certain Information Concerning Parent and Merger Sub.”

The Merger Agreement and the summary included below are not intended to provide any factual information about the Company, its stockholders or executives, Parent or Merger Sub, their respective businesses, or the actual conduct of their respective businesses during the period prior to the consummation of the Merger. The representations, warranties and covenants contained in the Merger Agreement were made only as of specified dates for the purposes of such agreement, were solely for the benefit of the parties to the agreement and may be subject to qualifications and limitations agreed upon by the parties. In particular, in reviewing the representations, warranties and covenants contained in the Merger Agreement and described in the following summary, it is important to bear in mind that such representations, warranties and covenants were negotiated with the principal purpose of allocating risk between the parties, rather than establishing matters as facts. Such representations, warranties and covenants may also be subject to a contractual standard of materiality different from those generally applicable to stockholders and to reports and documents filed with the SEC, and in some cases were qualified by disclosures set forth in a confidential disclosure letter that was provided by the Company to Parent and Merger Sub but is not filed with the SEC as part of the Merger Agreement. Accordingly, investors and stockholders should not rely on such representations, warranties and covenants as characterizations of the actual state of facts or circumstances described therein without consideration of the entirety of the factual disclosures about the Company, Parent and Merger Sub made in this Offer to Purchase, the Schedule 14D-9 or reports filed with the SEC. Information concerning the subject matter of such representations, warranties and covenants, which do not purport to be accurate as of the date of this Offer to Purchase, may have changed since the date of the Merger Agreement, which subsequent information may or may not be fully reflected in this Offer to Purchase or the parties’ public disclosures.

The Merger Agreement

The Offer. The Merger Agreement provides that, subject to the terms set forth therein, Merger Sub will (and Parent will cause Merger Sub to) commence the Offer to purchase any and all of the outstanding Shares (other than any Shares owned by Parent, Merger Sub or the Company, or by any direct or indirect wholly owned subsidiary of Parent, Merger Sub or the Company, in each case as of the commencement of the Offer) at a price per Share, subject to the terms of the Offer and the Merger Agreement, equal to the Offer Price as promptly as practicable (but in no event more than ten business days) after the date of the Merger Agreement and that, on the terms and subject to the conditions set forth in the Merger Agreement and the Offer, including the satisfaction of all Offer Conditions, Merger Sub will (and Parent will cause Merger Sub to), at or as promptly as practicable following the Expiration Time (as it may be extended in accordance with the Merger Agreement but in any event within one business day thereof), irrevocably accept for payment, and, at or as promptly as practicable following the Acceptance Time, but in any event within one business day thereof, pay for, all Shares that are validly tendered and not validly withdrawn pursuant to the Offer. Unless the Offer is extended pursuant to and in accordance with the Merger Agreement, the Offer will expire one minute after 11:59 p.m., New York City time, on April 4, 2025, which is the 20th business day following (and including the day of) the commencement of the Offer. In the event that the Offer is extended pursuant to and in accordance with the Merger Agreement, then the Offer will expire on the date and at the time to which the Offer has been so extended.

42

The obligation of Merger Sub to, and of Parent to cause Merger Sub to, irrevocably accept for payment and pay for Shares validly tendered and not validly withdrawn pursuant to the Offer are subject only to the satisfaction of the Offer Conditions. Parent and Merger Sub expressly reserve the right, at any time and from time to time, to waive, in whole or in part, any of the Offer Conditions and to make any change in the terms of or conditions to the Offer in a manner consistent with the terms of the Merger Agreement or to increase the Offer Price; provided, however, that notwithstanding the foregoing or anything to the contrary set forth therein, without the prior written consent of the Company, Parent and Merger Sub may not (and Parent shall not permit Merger Sub to): (i) waive or modify the Minimum Condition, the No Injunction Condition (as defined herein) or the No Termination Condition (as defined herein); or (ii) make any change in the terms of or conditions to the Offer that: (A) changes the form of consideration to be paid in the Offer; (B) decreases the Offer Price or the number of Shares sought in the Offer; (C) extends the Offer or the Expiration Time, except as permitted or required by the Merger Agreement; (D) imposes conditions or requirements on the Offer other than the Offer Conditions; (E) amends or modifies any term or condition of the Offer in any manner that is (or would reasonably be expected to be) material and adverse to the Company stockholders; or (F) would, individually or in the aggregate, reasonably be expected to prevent or materially delay the consummation of the Offer or prevent, materially delay or materially impair the ability of Parent or Merger Sub to consummate the Offer, the Merger or the other Transactions contemplated by the Merger Agreement.

Notwithstanding the foregoing, the Merger Agreement further provides that Parent and Merger Sub may not extend the Offer beyond the Termination Date without the prior written consent of the Company in its sole and absolute discretion.

The Merger. The Merger Agreement provides that, on the terms and subject to the conditions set forth in the Merger Agreement and in accordance with the DGCL, at the Effective Time, Merger Sub will merge with and into the Company. As a result of the Merger, the separate corporate existence of Merger Sub will cease, and the Company will continue as the Surviving Corporation and as an indirect wholly owned subsidiary of Parent. The Merger will be governed by and effected pursuant to Section 251(h) of the DGCL. The consummation of the Merger (the “Closing”) will take place as soon as practicable following the Acceptance Time without a vote of the Company stockholders pursuant to the DGCL (and in any event no later than one business day thereafter) subject to the satisfaction or, if permitted by applicable law, waiver of the conditions to the Merger described in the subsection “- Conditions to the Merger.” On the date upon which the Closing occurs (the “Closing Date”), the parties will file the Certificate of Merger, with respect to the Merger, with the Secretary of State of the State

43

of Delaware in accordance with the DGCL and shall take such further actions as may be required to make the Merger effective on such date. The Merger will become effective at the Effective Time. At the Effective Time all of the property, rights, privileges, immunities, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation, and all of the debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation, in each case, except as provided by the DGCL.

Certificate of Incorporation and Bylaws. At the Effective Time, (a) by virtue of the Merger and without necessity of further action by the Company or any other person, the certificate of incorporation of the Company will be amended and restated in its entirety to read as set forth on Annex B to the Merger Agreement and (b) without necessity of further action by the Company or any other person, the bylaws of the Company shall be amended and restated in their entirety to read in their entirety as set forth on Annex C to the Merger Agreement.

Directors and Officers. At the Effective Time, the Company and the Surviving Corporation will take all necessary action such that (a) the directors of Merger Sub immediately prior to the Effective Time, or such other individuals designated by Parent as of the Effective Time, will become the directors of the Surviving Corporation and (b) the officers of the Company immediately prior to the Effective Time, or such other individuals designated by Parent as of the Effective Time, will become the officers of the Surviving Corporation.

Effect on Capital Stock. On the terms and subject to the conditions set forth in the Merger Agreement, at the Effective Time: each Share that is issued and outstanding immediately prior to the Effective Time (excluding (a) Canceled Shares, (b) any Accepted Shares and (c) any Dissenting Shares) will be canceled and extinguished and automatically converted into the right to receive the Merger Consideration, without interest thereon and subject to any applicable withholding tax pursuant to the Merger Agreement and the CVR Agreement; provided that, at the election of Parent, any Shares owned by any direct or indirect subsidiary of the Company that are not Accepted Shares will instead receive shares of the Surviving Corporation of equivalent value; each Canceled Share or Accepted Share will, in each case, be canceled and extinguished, without any conversion thereof or consideration paid therefor, at the Effective Time by virtue of the Merger; and each share of common stock, par value $0.01 per share, of Merger Sub that is issued and outstanding immediately prior to the Effective Time will be converted into and become one validly issued, fully paid and nonassessable share of common stock, par value $0.01 per share of the Surviving Corporation, and, from and after the Effective Time, will constitute the only outstanding shares of capital stock of the Surviving Corporation.

Dissenting Shares will not be converted into, or represent the right to receive, the Merger Consideration pursuant to the Merger Agreement, but instead the holder of such Dissenting Shares will be entitled to receive such consideration as may be determined to be due to such person in respect of such Dissenting Shares pursuant to Section 262 of the DGCL. However, all Dissenting Shares that are held by Company stockholders (or beneficially owned by a beneficial owner that made an appraisal demand with respect thereto) who shall have failed to perfect or who shall have effectively withdrawn or otherwise lost or forfeited their rights to appraisal of these Dissenting Shares under Section 262 of the DGCL will no longer be considered to be Dissenting Shares and will be deemed to have been converted into, and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration, without interest and subject to any applicable withholding tax, on the terms and conditions set forth in the Merger Agreement.

Treatment of Stock Options, Other Equity Awards and Warrants. Pursuant to the terms of the Merger Agreement, effective as of immediately prior to the Effective Time, (i) each Company Option that is outstanding and unexercised immediately prior thereto will by virtue of the Merger automatically be canceled and terminated without any consideration payable therefor, (ii) each Company RSU that is outstanding as of immediately prior to the Effective Time (including, for clarity, any Company PSUs that are subject solely to service-vesting conditions as of the Effective Time) (a) will accelerate and become fully vested, and (b) will automatically be canceled and converted into the right to receive the RSU Consideration, and (iii) each Company PSU that is outstanding and vested as of immediately prior to the Effective Time (or that will become vested as required

44

under the terms of the applicable Company stock plan and/or governing award or other agreements in place as of the date of the Merger Agreement), will automatically be canceled and converted into the right to receive the PSU Consideration, and each other Company PSU that is outstanding immediately prior to the Effective Time shall be canceled and terminated without any consideration payable therefor. Pursuant to the terms of the Merger Agreement, at the Effective Time, each Company Warrant that is outstanding and unexercised as of immediately prior to the Effective Time shall be canceled and extinguished for no consideration pursuant to the terms thereof.

Treatment of Employee Stock Purchase Plan. Prior to the Effective Time, and subject to the prior review and reasonable approval of Parent (which may not be unreasonably withheld, conditioned or delayed), the Company Board (or, if appropriate, the committee administering the Company’s 2013 Employee Stock Purchase Plan (as amended, the “Company ESPP”)) will pass such resolutions and take all actions reasonably necessary with respect to the Company ESPP to provide that (i) except for the offering periods under the Company ESPP in effect on the date of the Merger Agreement (the “Final Offering Periods”), no new offering period will commence, and no existing offering period will be extended, following the date of the Merger Agreement unless and until the Merger Agreement is terminated; (ii) from and after the date of the Merger Agreement, no new participants will be permitted to participate in the Company ESPP and participants will not be permitted to increase their payroll deductions (or make separate non-payroll contributions) or purchase elections from those in effect on the date of the Merger Agreement; and (iii) subject to the consummation of the Merger, the Company ESPP will terminate as of the Effective Time. If the Effective Time occurs: (A) during one or more of the Final Offering Periods, (x) the final exercise date(s) under the Company ESPP will be such date as the Company determines in its sole discretion (provided that such date will be no later than the date that is five days prior to the Effective Time (the “Final Exercise Date”)), and (y) each Company ESPP participant’s accumulated contributions under the Company ESPP will be used to purchase whole Shares in accordance with the terms of the Company ESPP as of the Final Exercise Date, which Shares, to the extent outstanding immediately prior to the Effective Time, will be canceled at the Effective Time in exchange for the right to receive the Merger Consideration in accordance with the Merger Agreement; or (B) after the end of the Final Offering Periods, all amounts allocated to each participant’s account under the Company ESPP at the end of each of the Final Offering Periods will thereupon be used to purchase whole Shares under the terms of the Company ESPP for such offering periods, which Shares, to the extent outstanding immediately prior to the Effective Time, will be canceled at the Effective Time in exchange for the right to receive the Merger Consideration in accordance with the Merger Agreement. As promptly as practicable following the purchase of the Shares in accordance with the foregoing clauses (A) or (B), the Company will return to each participant the funds, if any, that remain in such participant’s account after such purchase. The Company will provide, subject to the prior review and reasonable approval of Parent (which may not be unreasonably withheld, conditioned or delayed), all required notices of the foregoing to the participants in accordance with the Company ESPP.

Representations and Warranties. In the Merger Agreement, the Company has made customary representations and warranties to Parent and Merger Sub, which are qualified by information set forth in (i) a confidential disclosure letter of the Company to Parent and Merger Sub in connection with the execution of the Merger Agreement and subject to the Merger Agreement (the “Company Disclosure Letter”) and (ii) certain disclosures in the Company’s SEC filings since January 1, 2023 and publicly available at least two business days prior to the date of the Merger Agreement, including representations and warranties relating to: organization and qualification; subsidiaries; capitalization (including capitalization of the Company’s subsidiaries); corporate power and authority; the enforceability of the Merger Agreement; Company Board approval; the vote of Company stockholders required to approve the Merger if Section 251(h) of the DGCL was not in effect; required governmental consents and approvals; non-contravention of applicable law and orders and the organizational documents and contracts; SEC filings, financial statements, internal controls, disclosure controls and procedures, Nasdaq listing requirements and audit compliance; the absence of undisclosed liabilities; the absence of a Company Material Adverse Effect (as defined below) since December 31, 2023; the absence of certain changes to the business of the Company since September 30, 2024; information provided or included in the Schedule TO and other documents relating to the Offer; fees and expenses of the Company Financial Advisor (as defined in the Merger Agreement); employee benefit plans and employees; litigation; taxes; compliance with laws and

Each of Parent and Merger Sub has made customary representations and warranties to the Company with respect to, among other matters: organization and qualification; partnership or corporate power and authority; the enforceability of the Merger Agreement; information provided or included in the Schedule TO and other documents relating to the Offer; required governmental consents and approvals; non-contravention of applicable law and orders and their organizational documents and contracts; litigation; that each of Parent and Merger Sub is not an “interested stockholder” within the meaning of Section 203 of the DGCL; availability of sufficient funds from the Equity Commitment Letters; the operations of each of Parent and Merger Sub; brokers’ fees; and the absence of certain arrangements as set forth in the Merger Agreement.

Pursuant to the Merger Agreement, the Company has represented that the Company Board, at a meeting duly called and held at which all of the directors of the Company were present, duly and unanimously (i) determined that the Merger Agreement and the Transactions contemplated thereby, including the Offer and the Merger, are advisable, fair to and in the best interests of the Company and its stockholders, and declared it advisable for the Company to enter into the Merger Agreement and consummate the Transactions contemplated therein, (ii) approved and declared advisable the execution and delivery by the Company of the Merger Agreement, the performance by the Company of its covenants and agreements contained therein and the consummation of the Transactions contemplated by the Merger Agreement upon the terms and subject to the conditions contained therein, (iii) resolved that the Merger Agreement and the Merger be governed by Section 251(h) of the DGCL and that the Merger be effected as soon as practicable following the Acceptance Time without a vote of the Company stockholders, and (iv) resolved, subject to the terms and conditions set forth in the Merger Agreement, to recommend that the holders of the Shares accept the Offer and tender their Shares to Merger Sub pursuant to the Offer, which resolutions, except to the extent expressly permitted by the Merger Agreement, have not been rescinded, modified or withdrawn in any way.

Some of the representations and warranties in the Merger Agreement are qualified by materiality qualifications or a “Company Material Adverse Effect” clause. For purposes of the Merger Agreement, “Company Material Adverse Effect” means any change, occurrence, effect, event, circumstance or development (each an “Effect” and, collectively, “Effects”) that has had, or would reasonably be expected to have, a material adverse effect on the business, assets, liabilities, condition (financial or otherwise) or results of operations of the Company and its subsidiaries, taken as a whole. However, no Effect directly or indirectly resulting from, attributable to or arising out of any of the following will (either alone or in combination) be deemed to be or constitute a “Company Material Adverse Effect,” and no Effect directly or indirectly resulting from, attributable to or arising out of any of the following will (either alone or in combination) be taken into account when determining whether a “Company Material Adverse Effect” has occurred, in each case, to the extent such Effects do not disproportionately and adversely affect the Company and its subsidiaries relative to other similarly situated companies operating in any industry or industries in which the Company or its subsidiaries operate in the events of clauses (a) through (f) below (in which case, only the incremental disproportionate Effect or Effects may be deemed to be or constitute, or be taken into account in determining whether there has occurred, a “Company Material Adverse Effect”):

(a) general economic conditions (or changes in such conditions) in the United States or any other country or region in the world, or conditions in the global economy generally;

(b) conditions (or changes in such conditions) in the securities markets, capital markets, credit markets, currency markets or other financial markets in the United States or any other country or region in the world, including (i) changes in interest rates in the United States or any other country or region in the world and changes in exchange rates for the currencies of any countries and (ii) any suspension of trading in securities (whether equity, debt, derivative or hybrid securities) generally on any securities exchange or over-the-counter market operating in the United States or any other country or region in the world;

46

(c) general conditions (or changes in such conditions) in the industries in which the Company and its subsidiaries operate;

(d) political conditions (or changes in such conditions) in the United States or any other country or region in the world, or acts of war, sabotage or terrorism (including any escalation or general worsening of any such acts of war, sabotage or terrorism) in the United States or any other country or region in the world (including any acts of war or sanctions imposed in connection with the current disputes involving (i) the Russian Federation and Ukraine or (ii) Israel, Hamas, Lebanon, Syria, Iran and any other state or non-state actors involved);

(e) earthquakes, hurricanes, tsunamis, tornadoes, floods, epidemics, pandemics, mudslides, wildfires or other natural disasters, weather conditions and other force majeure events in the United States or any other country or region in the world;

(f) actual changes after the date of the Merger Agreement in law (or the interpretation thereof) or changes in GAAP or other accounting standards (or the interpretation thereof);

(g) the announcement of the Merger Agreement, or the pendency or consummation of the Transactions contemplated thereby, including the identity of Parent, Merger Sub or their affiliates (except that this clause will not apply with respect to any representation or warranty whose purposes is to address the consequences of the announcement of the Merger Agreement, or the pendency or consummation of the Transactions contemplated thereby);

(h) any actions to which Parent has expressly consented in writing, or which Parent has expressly requested in writing; provided, that this clause will not apply to any action taken or omitted to be taken pursuant to the interim operating covenants set forth in the Merger Agreement described in the “- Conduct of the Business Pending the Merger” subsection;

(i) changes in the Company’s stock price or the trading volume of the Company’s stock, in and of itself, or any failure by the Company to meet any estimates or expectations of the Company’s revenue, earnings or other financial performance or results of operations for any period, in and of itself, or any failure by the Company to meet any internal budgets, plans or forecasts of its revenues, earnings or other financial performance or results of operations, in and of itself (but not, in each case, the underlying cause of such changes or failures, unless such changes or failures would otherwise be excepted from this definition of a Company Material Adverse Effect); or

(j) any legal proceedings alleging breach of fiduciary duties made or brought by any of the current or former Company stockholders (directly on their own behalf or derivatively in the right of or otherwise on behalf of the Company) against the Company arising out of the Merger or in connection with any other Transactions contemplated by the Merger Agreement.

Conduct of Business Pending the Merger. The Merger Agreement provides that except (a) as described in Section 6.1 of the Company Disclosure Letter, (b) as required by applicable law, (c) as consented to in writing by Parent (which consent shall not be unreasonably withheld, conditioned or delayed, provided, that, Parent may, in its sole discretion, withhold its consent with respect to Sections 6.1(y)(i), (ii), (iii), (iv), (xxiii)(A) or (xxv) of the Merger Agreement, or the Company’s payment of any bonuses to any of its employees, officers, directors or consultants in accordance with Section 6.1(y)(xiii)(C) of the Merger Agreement (or subsection (xxx) to the extent related to the foregoing clauses)) or (d) as required or expressly provided for by the Merger Agreement, during the period from the date of the Merger Agreement and continuing until the earlier of the termination of the Merger Agreement or the Effective Time (the “Pre-Closing Period”), (x) the Company will and will cause each of its subsidiaries to conduct its operations in all material respects according to its ordinary course of business, consistent with past practice, and the Company will and will cause each of its subsidiaries to use its reasonable

47

best efforts to preserve intact in all material respects its material assets, properties, contracts, licenses and business organization and to preserve the present relationships with those persons having material business relationships with the Company or any of its subsidiaries; and (y) without limiting the generality of the foregoing, the Company will not, and will not permit any of its subsidiaries to:

48

49

50

Notwithstanding the foregoing, nothing in the Merger Agreement is intended to give Parent or Merger Sub, directly or indirectly, the right to control or direct the business or operations of the Company or any of its subsidiaries at any time prior to the Acceptance Time. Prior to the Acceptance Time, the Company and its subsidiaries shall exercise, consistent with the terms and conditions of the Merger Agreement, complete control and supervision over its business and operations.

No Solicitation. Except as otherwise described below, the Company has agreed that, during the Pre-Closing Period, it will not, it will cause its subsidiaries, directors and officers and the directors and officers of each of its subsidiaries not to, and it will use reasonable best efforts to cause its other representatives not to, directly or indirectly: (i) solicit, initiate, knowingly encourage or knowingly facilitate any Acquisition Proposal (as defined below); (ii) furnish to any person (other than Parent, Merger Sub or any designees or representatives of Parent or Merger Sub) any non-public information relating to the Company or any of its subsidiaries, or afford to any person (other than Parent, Merger Sub or any designees or representatives of Parent or Merger Sub) access to the business, properties, assets, books, records or other non-public information, or to any personnel, of the Company or any of its subsidiaries, in any such case in connection with any Acquisition Proposal; (iii) participate or engage in any discussions or negotiations with any person with respect to any Acquisition Proposal (except to notify any person of the Company’s no-solicitation obligations); (iv) enter into any merger agreement, purchase agreement, letter of intent or similar agreement with respect to an Acquisition Transaction (as defined below) (except for an Acceptable Confidentiality Agreement (as defined in the Merger Agreement)); (v) approve any transaction under, or any third party becoming an “interested stockholder” under, Section 203 of the DGCL; or (vi) approve, authorize, agree or publicly announce any intention to do any of the foregoing.

“Acquisition Proposal” means any inquiry, request for information, offer or proposal (other than an inquiry, request for information, offer or proposal by Parent or Merger Sub) to engage in an Acquisition Transaction or that would reasonably be expected to lead to an inquiry, request for information, offer or proposal for an Acquisition Transaction.

“Acquisition Transaction” means any transaction or series of related transactions (other than the Transactions contemplated by the Merger Agreement) resulting in: (a) any acquisition by any person or “group” (as defined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) of more than 20% of the outstanding voting securities of the Company or any tender offer or exchange offer that if consummated would result in any person or “group” (as defined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) beneficially owning more than 20% of the outstanding voting securities of the Company; (b) any share issuance, merger, consolidation, business combination, recapitalization, reorganization or other similar transaction involving the Company or its subsidiaries (i) pursuant to which any person or “group” (as defined in or under Section 13(d) of the Exchange Act) would hold more than 20% of the voting power of the Company, the surviving entity or the resulting direct or indirect parent of the Company or such surviving entity or (ii) as a result of which the Company stockholders (as a group) immediately prior to the consummation of such transaction would hold securities representing less than 80% of the voting power of the Company, the surviving entity or the resulting direct or indirect parent of the Company or such surviving entity after giving effect to the consummation of such transaction; (c) any sale, lease, exclusive license or other disposition (whether through any merger, reorganization, consolidation, tender offer, self-tender, exchange offer, stock acquisition, asset acquisition, binding share exchange, business combination, recapitalization, liquidation, dissolution, joint venture, licensing or similar transaction) of any Company Product or assets representing more than 20% of the assets of the Company and its subsidiaries on a consolidated basis based on the fair market value thereof or to which 20% or more of the Company’s aggregate revenues or earnings are attributable; or (d) any liquidation or dissolution of the Company; provided, however, the Merger and the Transactions contemplated by the Merger Agreement shall not be deemed an Acquisition Transaction in any case.

Except as otherwise described below, the Company has also agreed that, during the Pre-Closing Period, it will, it will cause its subsidiaries, directors and officers and the directors and officers of its subsidiaries to, and it will use reasonable best efforts to cause its other representatives to immediately cease all existing discussions or

51

negotiations with any person (other than Parent, Merger Sub and their representatives) with respect to an Acquisition Proposal. Further, the Company has also agreed to promptly (and in any event within 24 hours) after the date of the Merger Agreement terminate access by any person (other than Parent, Merger Sub and their representatives) to any physical or electronic data room relating to a potential Acquisition Proposal (or prior discussions in respect of a potential Acquisition Proposal) and request that each third party that has executed a confidentiality agreement (other than the Confidentiality Agreement) relating to a potential Acquisition Proposal promptly return to the Company or destroy all non-public documents and materials containing non-public information of the Company that has been furnished by the Company or any of its representatives to such persons pursuant to the terms of such confidentiality agreement.

Further, during the Pre-Closing Period, promptly, and in any event within one business day following receipt of an Acquisition Proposal, the Company will (i) provide Parent with written notice of such Acquisition Proposal, (ii) communicate to Parent the material terms and conditions of such Acquisition Proposal and the identity of the person making such Acquisition Proposal and (iii) provide Parent with copies of any documents provided to the Company or any of its representatives evidencing or delivered in connection with such Acquisition Proposal (and if such communication was made orally, a reasonably detailed written summary of such communication). The Company has agreed to keep Parent reasonably informed on a reasonably prompt basis (and in any event within one business day) of any material developments or negotiations with respect to any such Acquisition Proposal (including the status of or any material changes to the terms and conditions of an Acquisition Proposal submitted to the Company, including by providing copies of any revised or new documents delivered to the Company or any of its representatives evidencing or delivered in connection with such Acquisition Proposal). For the avoidance of doubt, all information provided to Parent pursuant to this subsection “- No Solicitation” will be subject to the terms of the Confidentiality Agreement. The Company will not enter into any agreement with any person that prohibits the Company from providing the information to Parent required under this subsection “- No Solicitation.”

Notwithstanding the restrictions described above, if at any time prior to the Acceptance Time, the Company or any of its representatives has received a bona fide written Acquisition Proposal from any third party that did not result from a non-de minimis breach of the no-solicitation provisions of the Merger Agreement which are described in this subsection “- No Solicitation” or of the Company Board Recommendation (as defined below) provisions which are described in the “- Company Board Recommendation; Termination for a Superior Proposal; Matching Rights” subsection, then if the Company Board (or a duly authorized committee thereof) determines in good faith, after consultation with its financial advisor(s) and outside legal counsel, that such Acquisition Proposal constitutes or is reasonably likely to lead to a Superior Proposal and that the failure to take such action described in clause (a), (b) or (c) below would be inconsistent with its fiduciary duties under applicable law, then the Company and any of its representatives may (a) enter into an Acceptable Confidentiality Agreement with such person or group of persons in accordance with the terms of the Merger Agreement, (b) furnish information with respect to the Company and its subsidiaries to such person or group of persons making the Acquisition Proposal (provided that (i) the Company will substantially concurrently provide or make available to Parent any non-public information concerning the Company that is provided to such person or group of persons and which was not previously provided or made available to Parent and (ii) the Company shall have entered into an Acceptable Confidentiality Agreement with such person or group of persons in accordance with the terms of the Merger Agreement) and (c) participate and engage in discussions or negotiations with the person or group of persons making such Acquisition Proposal regarding the Acquisition Proposal. Prior to or substantially concurrently with the Company first taking any of the actions described in clauses (a), (b) or (c) of the immediately preceding sentence, the Company will provide written notice to Parent of the determination of the Company Board (or a duly authorized committee thereof) made pursuant to the immediately preceding sentence with respect to an Acquisition Proposal. Notwithstanding anything to the contrary set forth in this subsection “- No Solicitation” or in the Company Board Recommendation provisions which are described in the “- Company Board Recommendation; Termination for a Superior Proposal; Matching Rights” subsection, the Company shall be permitted to terminate or waive any “standstill” provision of any such confidentiality or similar agreement to the extent such standstill provisions would prohibit a person from making an Acquisition Proposal privately to the Company Board if the Company Board (or a committee thereof) determines in

52

good faith, after consultation with its outside legal counsel, that failure to take such action would be inconsistent with the directors’ fiduciary duties under applicable law.

The Company has also agreed that any breach of the no-solicitation provisions of the Merger Agreement by any of its representatives will be deemed a breach of the applicable section of the Merger Agreement by the Company.

“Superior Proposal” means a bona fide written Acquisition Proposal that did not result from a non-de minimis breach of the no-solicitation or the Company Board Recommendation provisions of the Merger Agreement as described in this subsection “- No Solicitation” and “- Company Board Recommendation; Termination for a Superior Proposal; Matching Rights,” respectively, for an Acquisition Transaction on terms that the Company Board (or a duly authorized committee thereof) determines in good faith, after consultation with outside legal counsel and its financial advisor(s), taking into account all legal, financial, regulatory and other aspects of the proposal, is reasonably likely to be consummated in accordance with its terms and is more favorable to the Company stockholders, from a financial point of view, than the terms of the Offer and Merger (including any adjustment to the terms and conditions proposed by Parent in response to such proposal); provided, however, that for purposes of the reference to an “Acquisition Proposal” or an “Acquisition Transaction” in this definition of a “Superior Proposal,” all references to “20%” and “80%” will each be deemed to be references to “50%.”

Company Board Recommendation; Termination for a Superior Proposal; Matching Rights. Subject to the provisions described below, the Company Board (or a duly authorized committee thereof) will recommend that the Company stockholders accept the Offer and tender their Shares to Merger Sub pursuant to the Offer (the “Company Board Recommendation”). The Company has agreed, subject to the following paragraph, that neither the Company Board nor any committee thereof will (i) withdraw, amend, modify or qualify in a manner adverse to Parent or Merger Sub, or publicly propose to withhold, withdraw, amend, modify or qualify in a manner adverse to Parent or Merger Sub, the Company Board Recommendation; (ii) publicly approve, adopt, declare advisable or recommend an Acquisition Proposal or approve, adopt, recommend or declare advisable or enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other similar agreement (except for an Acceptable Confidentiality Agreement relating to an Acquisition Proposal), (iii) fail to include the Company Board Recommendation in the Schedule 14D-9 when disseminated to the Company stockholders or fail to publicly reaffirm the Company Board Recommendation upon written request of Parent within the earlier of three business days prior to the then-scheduled Expiration Time or five business days after Parent requests in writing such reaffirmation with respect to such Acquisition Proposal, or (iv) (A) if any Acquisition Proposal has been publicly disclosed, fail to publicly recommend against such Acquisition Proposal within ten business days after a request from Parent to do so, or (B) if any tender offer or exchange offer for the outstanding Shares is commenced pursuant to Rule 14d-2 under the Exchange Act (other than by Parent or an affiliate of Parent), fail to recommend, within ten business days after such commencement, against acceptance of such tender offer or exchange offer by the Company stockholders (each of clauses (i), (ii), (iii) and (iv), a “Company Board Recommendation Change”); provided, however, that, notwithstanding anything herein to the contrary, a “stop, look and listen” communication by the Company Board or any committee thereof to the Company stockholders pursuant to Rule 14d-9(f) of the Exchange Act shall not be deemed in and of itself to be a Company Board Recommendation Change, provided that in such disclosure, the Company shall state that the Company Board Recommendation continues to be in effect unless, prior to the time of such public disclosure, a Company Board Recommendation Change has been made in compliance with the Merger Agreement.

Notwithstanding the foregoing or anything to the contrary set forth in the Merger Agreement, at any time prior to the Acceptance Time, the Company Board (or a duly authorized committee thereof) may (i) in response to (A) the receipt of an Acquisition Proposal received after the date of the Merger Agreement that did not result from a non-de minimis breach of the “- No Solicitation” and “- Company Board Recommendation; Termination for a Superior Proposal; Matching Rights” subsections, or (B) the occurrence of an Intervening Event (as defined

53

below), effect a Company Board Recommendation Change, or (ii) in response to an Acquisition Proposal received after the date of the Merger Agreement that did not result from a non-de minimis breach of the “- No Solicitation” and “- Company Board Recommendation; Termination for a Superior Proposal; Matching Rights” subsections, terminate the Merger Agreement pursuant to the terms of the Merger Agreement to concurrently enter into a definitive agreement with respect to such applicable Acquisition Proposal, provided that (1) the Company Board (or a duly authorized committee thereof) must determine in good faith (after consultation with its outside legal counsel) that the failure to take such action would be inconsistent with its fiduciary duties under applicable law, (2) in the case of receipt of an Acquisition Proposal, the Company Board (or a duly authorized committee thereof) must determine in good faith (after consultation with its financial advisor(s) and outside legal counsel) that such Acquisition Proposal constitutes a Superior Proposal, or, in the case of an Intervening Event, that an Intervening Event has occurred; (3) the Company must provide written notice to Parent at least five business days prior to effecting a Company Board Recommendation Change or, solely in the case of a Superior Proposal, terminating the Merger Agreement pursuant to the terms of the Merger Agreement to concurrently enter into a definitive agreement with respect to a Superior Proposal of its intent to take such action, specifying the reasons therefor (a “Change of Recommendation Notice”); (4) prior to effecting such Company Board Recommendation Change or terminating the Merger Agreement to concurrently enter into a definitive agreement with respect to a Superior Proposal, the Company must, and must cause its representatives to, be reasonably available to negotiate with Parent in good faith (to the extent Parent desires to negotiate) during such five business day period to make such adjustments to the terms and conditions of the Merger Agreement as would obviate the basis for a Company Board Recommendation Change or, solely in the case of a Superior Proposal, the termination of the Merger Agreement with respect to a Superior Proposal; and (5) no earlier than the end of such five business day period, the Company Board (or a duly authorized committee thereof) must determine in good faith (after consultation with its financial advisor(s) and outside legal counsel), after considering any amendments to the terms and conditions of the Merger Agreement proposed by Parent in a binding written offer during the five business day period, that the failure to take such action would be inconsistent with its fiduciary duties under applicable law (and, in the case of receipt of such Acquisition Proposal, that such Acquisition Proposal continues to constitute a Superior Proposal).

Following delivery of a Change of Recommendation Notice: (x) in the case of a Superior Proposal, in the event of any change to the financial terms (including any change to the amount or form of consideration payable) or other material revision to the terms or conditions of such Acquisition Proposal, the Company must provide a new Change of Recommendation Notice to Parent, and any Company Board Recommendation Change or termination of the Merger Agreement to enter into a definitive agreement with respect to a Superior Proposal following delivery of such new Change of Recommendation Notice will again be subject to the procedures described in clauses (3) through (5) above (but the five business day period shall instead be two business days) and (y) in the case of an Intervening Event, in the event of any material change to such Intervening Event, the Company shall provide a new Change of Recommendation Notice to Parent, and any Company Board Recommendation Change following delivery of such new Change of Recommendation Notice shall again be subject to clauses (3) through (5) of the immediately preceding sentence (but the five business day period shall instead be two business days).

“Intervening Event” means a material Effect that occurs or arises after the date of the Merger Agreement that (a) was not known to, nor reasonably foreseeable by, the Company Board as of the date of the Merger Agreement or, if known, the material consequences of which were not reasonably foreseeable to the Company Board as of the date of the Merger Agreement and (b) does not relate to (i) an Acquisition Proposal, (ii) any change, in and of itself, in the market price or trading volume of the Shares, (iii) any change in conditions generally (including any regulatory changes) affecting the industries or sectors in which the Company, Parent or any of their respective subsidiaries operates, (iv) clearance of the Merger under the antitrust laws or any matters relating thereto or arising therefrom or (v) the fact that the Company or any of its subsidiaries exceeds any internal or published industry analyst projections or forecasts or estimates of revenue, earnings or other financial or operating metrics for any period; provided, however, that the underlying cause of any Effect in the preceding

54

clauses (ii) or (v) may constitute or be taken into account in determining whether there has been an Intervening Event (unless otherwise excluded under another clause of this definition).

Best Efforts. (a) Upon the terms and subject to the conditions set forth in the Merger Agreement, subject to Section 7.2 set forth therein, each of Parent, Merger Sub and the Company has agreed to use its best efforts to take, or cause to be taken, all actions that are necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Offer, the Merger and each of the other transactions contemplated by the Merger Agreement, including using best efforts to (i) cause (A) each of the Offer Conditions described in Section 15 “- Conditions to the Offer” to be satisfied and (B) each of the conditions to the Merger described in the subsection “- Conditions to the Merger” to be satisfied as promptly as practicable after the date of the Merger Agreement; (ii) obtain, as promptly as practicable after the date of the Merger Agreement, and maintain all necessary actions or non-actions and consents from governmental authorities and make all necessary registrations, declarations and filings with governmental authorities, that are necessary to consummate the Offer and the Merger; (iii) resist, contest, appeal and remove any legal proceeding and have vacated, lifted, reversed or overturned any order, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents, restricts or restrains the consummation of the Transactions contemplated by the Merger Agreement, (including any legal proceeding or order in connection with the matters contemplated by the provisions described in the subsection “- Antitrust Obligations”), (iv) upon the reasonable written request of Parent or Merger Sub, obtain all necessary or appropriate consents under any material contracts to which the Company or any of its subsidiaries is a party in connection with the Merger Agreement and the consummation of the Transactions contemplated thereby; and (v) reasonably cooperate with the other party or parties with respect to any of the foregoing. Notwithstanding anything to the contrary in the Merger Agreement, the Company will not be required prior to the Effective Time to pay any consent or other similar fee, “profit-sharing” or other similar payment or other consideration (including increased rent or other similar payments or agree to enter into any amendments, supplements or other modifications to (or waivers of) the existing terms of any contract), or provide additional security (including a guaranty) or otherwise assume or incur or agree to assume or incur any non-de minimis liability that is not conditioned upon the Closing, to obtain any consent of any person (including any governmental authority) under any contract.

(b) Parent has agreed, on behalf of itself and its controlled affiliates, that, between the date of the Merger Agreement and the Effective Time, Parent shall not, and shall cause its controlled affiliates not to, directly or indirectly, acquire, purchase, lease or license (or agree to acquire, purchase, lease or license), by merging with or into or consolidating with, or by purchasing a substantial portion of the assets of or equity in, or by any other manner, any business or any corporation, partnership, association or other business organization or division thereof, or any securities or collection of assets, if doing so would or would reasonably be expected to prevent, prohibit, materially impede or materially delay the satisfaction of the Regulatory Approvals Condition or the No Injunction Condition as set forth in Merger Agreement.

Antitrust Obligations. Each of Parent and the Company have agreed to file any submission required pursuant to any foreign antitrust law of certain jurisdictions set forth in the Company Disclosure Letter as soon as practicable after the date of the Merger Agreement (unless a later date is mutually agreed between the parties). Each of Parent and the Company shall (i) cooperate and coordinate with the other in the identification and making of such filings, (ii) promptly use their best efforts to supply the other with any information and documentary material that may be required in order to make such filings, (iii) promptly use their best efforts to supply any information that reasonably may be required or requested by any governmental authority responsible for the enforcement of any antitrust law and (iv) promptly use their best efforts to cause the expiration or termination of any applicable waiting periods under any foreign antitrust laws as soon as practicable, and to avoid any impediment to the consummation of the Offer or the Merger under any antitrust law, including cooperating with each other and using their respective best efforts to contest and resist any legal proceeding, including by defending through litigation (including through appeal) and seek to have vacated, lifted, reversed or overturned any order that may result from such legal proceedings, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents or restricts consummation of the Transactions contemplated by the

55

Merger Agreement, provided that, notwithstanding anything in the Merger Agreement to the contrary, Parent and Merger Sub and their respective affiliates shall not be obligated to, and the Company shall not without the prior written consent of Parent, take any action involving (A) proposing, negotiating, committing to and effecting, by consent decree, hold separate order or otherwise, conduct of business restrictions, a sale or disposition of assets or businesses or a license or grant of commercialization rights to businesses, product lines, fields of use, divisions, business arrangements, contracts, assets or interests therein of Parent or its affiliates (including, after the Closing, the Surviving Corporation and its affiliates), (B) amending any venture or other arrangement of Parent or its affiliates (including the Surviving Corporation and its affiliates), or (C) otherwise taking or committing to take actions with respect to any of the businesses, product lines, fields of use, or assets of Parent and its affiliates (including the Surviving Corporation and its affiliates), including any obligation to provide prior notification to governmental authorities for transactions that would not otherwise be required under any antitrust laws or to seek approvals from governmental authorities for future transactions, provided further that, at Parent’s express written request, the Company shall and shall cause its affiliates to take the foregoing actions so long as they are conditioned on the occurrence of the Acceptance Time. Neither party will agree to enter into any agreement with the United States Federal Trade Commission or any successor thereto (the “FTC”), the Antitrust Division of the United States Department of Justice or any successor thereto (the “DOJ”) or any other governmental authority not to consummate the Transactions contemplated by the Merger Agreement without the written consent of the other party.

Each of Parent and Merger Sub, on the one hand, and the Company, on the other hand, has agreed to promptly inform outside counsel for the other of any communication from any governmental authority regarding any of the Transactions contemplated by the Merger Agreement in connection with any filings or investigations with, by or before any governmental authority relating to the Merger Agreement or the Transactions contemplated by it, including any proceedings initiated by a private party. In connection with and without limiting the foregoing, to the extent reasonably practicable and unless prohibited by applicable law or by the applicable governmental authority, the parties have also agreed to (i) give outside counsel for the other party reasonable advance notice of all meetings and conference calls with any governmental authority relating to the Offer or the Merger, (ii) give outside counsel for each other an opportunity to participate in each of such meetings and conference calls, (iii) keep outside counsel for the other party reasonably apprised of any oral communications with any governmental authority in respect of the Offer or the Merger, (iv) cooperate in the filing of any analyses, presentations, memoranda, briefs, arguments, opinions or other written communications explaining or defending the Offer and the Merger, articulating any regulatory or competitive argument and/or responding to requests or objections made by any governmental authority, (v) provide outside counsel for each other with a reasonable advance opportunity to review and comment upon, and consider in good faith the views of the other with respect to, all written communications (including any analyses, presentations, memoranda, briefs, arguments and opinions) with a governmental authority relating to the Offer and the Merger, (vi) provide outside counsel for each other with copies of all written communications to or from any governmental authority relating to the Offer or the Merger, and (vii) cooperate and provide outside counsel for each other with a reasonable opportunity to participate in, and consider in good faith the views of the other with respect to, all material deliberations with respect to all efforts to satisfy the Regulatory Approvals Condition and the No Injunction Condition.

Notwithstanding anything in the Merger Agreement to the contrary, Parent shall after good faith consultation with the Company and after considering in good faith the Company’s views and comments, develop, direct and control the (i) strategy for obtaining all necessary actions or nonactions, waivers, consents, clearances, approvals and expirations or terminations of waiting periods so as to enable the Closing to occur as promptly as reasonably practicable, (ii) response to any request from, inquiry by or investigation by (including the timing, nature and substance of all such responses) any governmental authority with respect to the Offer, the Merger and the other transactions contemplated by the Merger Agreement, and (iii) strategy for the defense and settlement of any proceeding brought by or before any governmental authority that has authority to enforce any applicable foreign antitrust or competition laws.

56

Merger. Following the Acceptance Time, each of Parent, Merger Sub and the Company have agreed to take all necessary and appropriate actions to cause the Merger to become effective as soon as practicable after the Acceptance Time, without a meeting of the Company stockholders, in accordance with Section 251(h) of the DGCL and upon the terms and subject to the conditions of the Merger Agreement. The parties shall not, and each shall not permit and shall cause their respective representatives not to, take any action that could render Section 251(h) of the DGCL inapplicable to the Merger.

Public Statements and Disclosure. So long as the Merger Agreement is in effect, Parent and Merger Sub, on the one hand, and the Company, on the other hand, shall not, and shall cause their respective controlled affiliates not to, issue any press release or make any public statement with respect to the Merger, the Offer or the Merger Agreement without the prior written consent of the other party (which consent shall not be unreasonably withheld, conditioned or delayed), except (a) as may be required by applicable law or the rules or regulations of any applicable U.S. securities exchange or regulatory or governmental body to which the relevant party is subject, in which case, to the extent permitted by applicable law and practicable under the circumstances, the party proposing to issue such press release or make such public announcement shall consult in good faith with the other party before making any such public announcement, (b) with respect to any press release, filing, disclosure or other public statement by the Company expressly permitted by the Company Board Recommendation provisions which are described in the “- Company Board Recommendation; Termination for a Superior Proposal; Matching Rights” subsection (including to announce a Company Board Recommendation Change in accordance with such provisions) but subject to compliance in all respects with such provisions, (c) statements consistent with any release, filing disclosure or other public statements previously made in accordance with the Merger Agreement or (d) public statements regarding the Transactions contemplated by the Merger Agreement in response to questions from the press, analysts, investors or those attending industry conferences, in each case, to the extent that such statements are not inconsistent in form and substance with previous press releases, public disclosures or public statements made jointly by the parties or approved by the parties, and otherwise in compliance with the Merger Agreement, and provided that such public statements do not reveal material nonpublic information regarding the Merger Agreement or the Transactions contemplated thereby. Prior to making any written (or prepared broad-based) communications to the officers or employees of the Company or any of its subsidiaries pertaining to compensation or benefit matters that are affected by the Transactions contemplated by the Merger Agreement or compensation or benefits that are payable or to be provided following the Effective Time, the Company shall provide Parent with a copy of the intended communication (or written summary of any prepared broad-based oral communication) and the Company shall provide Parent a reasonable period of time to review and comment on the communication, and the Company shall consider any timely comments in good faith.

Anti-Takeover Laws. If any state takeover law or state law that purports to limit or restrict business combinations or the ability to acquire or vote the Shares (including any “control share acquisition,” “fair price,” “moratorium,” “business combination” or other similar takeover law) becomes or is deemed applicable to the Merger Agreement, the Merger, the Offer or any other Transactions contemplated by the Merger Agreement, then Parent, Merger Sub and the Company will cooperate and take all action reasonably available to render such law inapplicable to the foregoing. Neither Parent, Merger Sub nor the Company will take any action that would cause the Merger Agreement, the Merger, the Offer or the other transactions contemplated by the Merger Agreement to be subject to the requirements imposed by any such takeover or similar laws.

Access. During the period commencing on the date of the Merger Agreement and continuing until the earlier to occur of the termination of the Merger Agreement pursuant to Article IX thereof and the Acceptance Time, the Company has agreed to afford Parent and its representatives reasonable access during normal business hours, upon reasonable advance written notice, to the properties, books, records and personnel of the Company and its subsidiaries, in each case, for the purposes of transition and integration planning during such period (and not for the purpose of any actual or potential adverse action or dispute between the parties or their affiliates) and promptly provide Parent and its representatives with all reasonably requested information regarding the Company and its subsidiaries as Parent may reasonably request; provided, however, that the Company may

57

restrict or otherwise prohibit access to any documents or information to the extent that (a) any applicable law requires the Company or any of its subsidiaries to restrict or otherwise prohibit access to such documents or information, (b) granting such access would violate any obligations of the Company or any of its subsidiaries with respect to confidentiality to any third party existing as of the date of the Merger Agreement, (c) access to such documents or information would reasonably be expected to result in a waiver of any attorney-client privilege, work product doctrine or other applicable privilege applicable to such documents or information or (d) such documents or information related to the valuation of the Company in connection with the Merger Agreement. In the event that the Company does not provide access or information in reliance on clauses (a), (b) or (c) of the preceding sentence, it shall use its reasonable best efforts to communicate the applicable information to Parent in a way that would not violate any applicable law, contract or obligation or waive such a privilege. Any investigation conducted pursuant to the access contemplated by the provisions described in this paragraph shall be conducted in a manner that does not unreasonably interfere with the conduct of the business of the Company or any of its subsidiaries or create a risk of damage or destruction to any property or assets of the Company or any of its subsidiaries, shall be subject to the Company’s reasonable security measures, and shall not include the right to perform invasive testing without the Company’s prior written consent. The terms and conditions of the Confidentiality Agreement shall apply to any information obtained by Parent or any of its representatives in connection with any investigation conducted pursuant to the access contemplated by the provisions described in this paragraph. Nothing in the provisions described in this paragraph will be construed to require the Company or any representatives of any of the foregoing to prepare any new appraisals or opinions.

The Company shall notify Parent (x) substantially concurrently when it notifies the agent under the Existing LSA, of the occurrence of any Default or Event of Default (each as defined in the Existing LSA) under the Existing LSA and (y) within one business day of the receipt of any notice from the agent or any lender under the Existing LSA of the occurrence of a Default or Event of Default (each as defined in the Existing LSA) under the Existing LSA. The Company shall deliver to Parent copies of any financial reports, financial information, compliance certificates or similar information delivered pursuant to Sections 7.1(a) through (d) or Section 7.1(1) of the Existing LSA substantially concurrently with delivery thereof to the agent under the Existing LSA (it being agreed among the parties that any extensions granted by the agent thereunder shall automatically apply to any delivery requirement under the provisions described in this paragraph).

Section 16(b) Exemption. The Company shall take all actions reasonably necessary to cause the dispositions of equity securities of the Company (including “derivative securities” (as defined in Rule 16a-1(c) under the Exchange Act)) in connection with the Transactions contemplated by the Merger Agreement by any director or executive officer of the Company who is a covered person of the Company for purposes of Section 16 of the Exchange Act and the rules and regulations thereunder to be exempt under Rule 16b-3 promulgated under the Exchange Act.

Directors’ and Officers’ Indemnification and Insurance. From and for a period of six years following the Effective Time, the Surviving Corporation and the Surviving Corporation’s subsidiaries shall honor and fulfill in all respects the obligations of the Company and its subsidiaries under (i) the indemnification agreements that have been made available to Parent prior to the date of the Merger Agreement between (A) the Company and its subsidiaries and any of their current or former directors and officers and any person who becomes a director or officer of the Company or any of its subsidiaries and (B) the Company or any corporation, partnership, joint venture, trust, pension or other employee benefit plan or enterprise and any person serving or who served as a director, officer, member, manager, partner, trustee or other fiduciary of any of the foregoing at the request of the Company or any of its subsidiaries, in each case, prior to the Effective Time (the “Indemnified Persons”), and (ii) indemnification, expense advancement and exculpation provisions in the certificate of incorporation or bylaws of the Company and in the certificate of incorporation or bylaws (or equivalent governing documents) of any subsidiary of the Company, in each case as in effect on the date of the Merger Agreement. In addition, during the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, the Surviving Corporation and its subsidiaries shall cause the certificates of incorporation and bylaws of the Surviving Corporation and its subsidiaries to contain provisions with respect to elimination of liability of

58

directors, indemnification, exculpation and the advancement of expenses that are no less favorable to the Indemnified Persons than the indemnification, exculpation and advancement of expenses provisions contained in the certificates of incorporation and bylaws of the Company and its subsidiaries as of the date of the Merger Agreement and during such six year period, such provisions shall not be repealed, amended or otherwise modified (whether by merger, consolidation, division, conversion, domestication, transfer, continuance, share exchange, operation of law or otherwise) in any manner that is material and adverse to the Indemnified Persons except as required by applicable law or as provided below.

Without limiting the generality of the provisions described in the previous paragraph, during the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, to the fullest extent permitted by applicable law, the Surviving Corporation and its subsidiaries shall indemnify and hold harmless each Indemnified Person from and against any costs, fees and expenses (including reasonable attorneys’ fees and investigation expenses), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement of or in connection with any threatened or actual action, suit, claim, proceeding, investigation, arbitration or inquiry, whether civil, criminal, administrative or investigative (each an “Indemnified Proceeding”), to the extent such Indemnified Proceeding arises directly or indirectly out of or pertains or relates directly or indirectly to (i) any action or omission or alleged action or omission in such Indemnified Person’s capacity as (or the fact that such Indemnified Person is or was) a director or officer of the Company or other controlled affiliates (including as a fiduciary with respect to any employment benefit plan) or by reason of the fact that such Indemnified Person is or was serving as a director or officer of the Company or its controlled affiliates or at the request of the Company and its subsidiaries as such (including as a fiduciary with respect to any employee benefit plan) of another person (regardless, in each case, of whether such action or omission, or alleged action or omission, occurred prior to or at the Effective Time), (ii) any of the Transactions contemplated by the Merger Agreement or (iii) the enforcement of any of the rights of such Indemnified Person (or his or her heirs or legal representatives) under the provisions which are described in this “- Directors’ and Officers’ Indemnification and Insurance” subsection, provided that if, at any time prior to the sixth anniversary of the Effective Time, any Indemnified Person delivers to the Surviving Corporation or any of its subsidiaries a written notice of any prospective, threatened or actual Indemnified Proceeding for which indemnification or advancement may be sought under the provisions described in this “- Directors’ and Officers’ Indemnification and Insurance” subsection, then the obligations of the Surviving Corporation and its subsidiaries under the provisions described in this “- Directors’ and Officers’ Indemnification and Insurance” subsection shall survive the sixth anniversary of the Effective Time until such time as such claim is fully and finally resolved. In addition, during the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, to the fullest extent permitted by applicable law, the Surviving Corporation and its subsidiaries shall advance, prior to the final disposition of any Indemnified Proceeding for which indemnification may be sought under the Merger Agreement, promptly following a request by an Indemnified Person therefor, all costs, fees and expenses (including reasonable attorneys’ fees and investigation expenses) incurred by such Indemnified Person in connection with any such Indemnified Proceeding upon receipt of an undertaking by such Indemnified Person, to the extent required by law, to repay such advances if it is ultimately decided in a final, non-appealable judgment by a court of competent jurisdiction that such Indemnified Person is not entitled to indemnification therefor hereunder.

The Merger Agreement also provides that, during the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, Parent shall cause the Surviving Corporation to maintain in effect for the benefit of the directors and officers of the Company, as of the date of the Merger Agreement and as of the Effective Time, an insurance and indemnification policy that provides coverage for events occurring prior to the Effective Time (the “D&O Insurance”) that is substantially equivalent to and in any event providing coverage, terms, conditions, retentions, limits of liability, deductibles and amounts not less favorable to the insured persons than the policies of the Company in effect as of the date of the Merger Agreement; provided that the Surviving Corporation will not be required to pay total premium for the D&O Insurance for such six year term in excess of 300% of the last annual premium paid prior to the date of the Merger Agreement (the “Maximum Amount”), but in such case shall purchase coverage as favorable to the insured persons as is available for such amount as long as such substitution does not result in gaps or lapses of coverage with respect to matters occurring at or prior

59

to the Effective Time. The provisions of the immediately preceding sentence shall be deemed to have been satisfied if prepaid D&O Insurance “tail” policies have been obtained by the Company prior to the Effective Time, provided that in no case shall the total premium for such policies exceed the Maximum Amount. The Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) maintain the D&O Insurance “tail” policy in full force and effect and continue to honor their respective obligations thereunder, during the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time.

If any Indemnified Person notifies the Surviving Corporation on or prior to the sixth anniversary of the Effective Time that a claim, action, suit, proceeding or investigation (whether arising before, at or after the Effective Time) has been made, brought or threatened against such Indemnified Person, the provisions described in this “- Directors’ and Officers’ Indemnification and Insurance” subsection shall continue in effect with respect to such claim, action, suit, proceeding or investigation until the final, non-appealable disposition of such claim, action, suit, proceeding or investigation.

In the event that the Surviving Corporation (or any of its successors or assigns) (i) consolidates with or merges into any other person and is not the continuing or surviving corporation or entity of such consolidation or merger or engages in any division transaction, or (ii) transfers, conveys or otherwise disposes of all or substantially all of its properties and assets to any person or effects any division transaction, then, in each such case, the Surviving Corporation will make proper provision so that the successors and assigns of the Surviving Corporation, as the case may be, will assume all of the obligations thereof set forth in the provisions described in this “- Directors’ and Officers’ Indemnification and Insurance” subsection, unless such assumption occurs by operation of law.

The provisions described in this “- Directors’ and Officers’ Indemnification and Insurance” subsection will survive the consummation of the Merger and is intended to benefit, and from and after the Effective Time will be enforceable by, each of the Indemnified Persons and their respective successors, assigns, heirs and legal representatives, and will not be amended, terminated, altered, repealed or modified from and after the Effective Time in such a manner as to materially and adversely affect any Indemnified Person without the written consent of such affected Indemnified Person. The rights provided under the provisions described in this “- Directors’ and Officers’ Indemnification and Insurance” subsection will not be deemed to be exclusive of any other rights to which any Indemnified Person is entitled, whether pursuant to law, contract or otherwise, and are in addition to, and not in substitution for, any such other rights.

Employee Matters.

Pursuant to the Merger Agreement, for a period of six months following the Effective Time, the Surviving Corporation will (and Parent will cause the Surviving Corporation to) provide to each employee of the Company or any of its subsidiaries who, as of the Closing, continues their employment with Parent, the Company or any subsidiaries or affiliates thereof (each, a “Continuing Employee”) (i) a base salary or wage rate, as applicable, that is not less than the base salary or wage rate (as applicable) provided to such Continuing Employee immediately prior to the Effective Time, (ii) an annual target cash bonus opportunity that is not less than the annual target cash bonus opportunity provided to such Continuing Employee immediately prior to the Effective Time, and (iii) retirement, medical, dental and vision benefits (other than defined benefit pension benefits or retiree welfare benefits) that are, taken as a whole, no less favorable in the aggregate to such retirement, medical, dental and vision benefits provided to such Continuing Employee immediately prior to the Effective Time.

To the extent a Company employee benefit plan or any other employee benefit plan (excluding equity, equity-based or severance benefits) of Parent, the Surviving Corporation or any of their respective subsidiaries (together, the “New Plans”) is made available to any Continuing Employee on or following the Effective Time, Parent will cause to be granted to such Continuing Employee credit for all service with the Company, its affiliates or their respective predecessors prior to the Effective Time for all purposes (including for eligibility to participate, vesting and entitlement to (or level of) benefits where length of service is relevant); provided, however, that such service

60

need not be credited (i) for purposes of any defined benefit plan, (ii) to the extent that it would result in duplication of coverage or benefits, or (iii) to the extent such service was not credited under the applicable comparable Company employee benefit plan prior to the Effective Time. Parent shall (or shall cause the Surviving Corporation to), to the extent permitted by applicable law, use commercially reasonable efforts to provide that (x) each Continuing Employee will be immediately eligible to participate, without any waiting time, in any and all New Plans to the extent coverage under any such New Plan replaces coverage under a comparable Company employee benefit plan in which such Continuing Employee participates immediately before the Effective Time (such plans, collectively, the “Old Plans”), (y) for purposes of each New Plan providing medical, dental, pharmaceutical, vision and/or disability benefits to any Continuing Employee, all waiting periods, pre-existing condition exclusions, evidence of insurability requirements and actively-at-work or similar requirements of such New Plan will be waived for such Continuing Employee and his or her covered dependents to the extent they did not apply to the Continuing Employee under the corresponding Old Plan and any eligible expenses incurred by such Continuing Employee and his or her covered dependents during any unfinished portion of the plan year of the Old Plan ending on the date such employee’s participation in the corresponding New Plan begins will be given full credit under such New Plan for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such Continuing Employee and his or her covered dependents for the applicable plan year as if such amounts had been paid in accordance with such New Plan, and (z) the accounts of such Continuing Employees under any New Plan that is a flexible spending plan are credited with any unused balance in the account of such Continuing Employee under the applicable Old Plan.

Notwithstanding anything to the contrary set forth in the Merger Agreement, no provision of the Merger Agreement shall be deemed to (i) guarantee employment for any period of time for, or preclude the ability of Parent, the Company, the Surviving Corporation or their respective Subsidiaries to terminate, any Continuing Employee for any reason, or (ii) require Parent, the Company, the Surviving Corporation or their respective Subsidiaries to continue any employee benefit plan or prevent the amendment, modification or termination thereof after the Effective Time. The provisions described in this “- Employee Matters” subsection are solely for the benefit of the parties to the Merger Agreement, and no Continuing Employee (including any beneficiary or dependent thereof) shall be regarded for any purpose as a third party beneficiary of the Merger Agreement, and no provision described in this “- Employee Matters” subsection shall create such rights in any such persons.

Obligations of Merger Sub. Parent shall take all actions necessary to cause Merger Sub and the Surviving Corporation to perform, satisfy and discharge on a timely basis their respective covenants, obligations and liabilities under the Merger Agreement before and after the Effective Time, as applicable (including, with respect to Merger Sub, to consummate the Transactions contemplated by the Merger Agreement upon the terms and subject to the conditions set forth therein).

Certain Litigation. The Company shall promptly (and in any event within two business days) advise Parent of any legal proceeding commenced after the date of the Merger Agreement against the Company and/or any of its directors or officers (in their capacity as such) by any Company stockholders (on their own behalf or on behalf of the Company) relating to the Merger Agreement or the Transactions contemplated thereby, and shall keep Parent reasonably informed regarding any such legal proceeding, including as to the proposed strategy and other significant decisions with respect to such legal proceeding. The Company has agreed to give Parent the right to review and comment on all material filings or responses to be made by the Company in connection with such legal proceedings and the opportunity to consult with the Company (and the Company shall consider in good faith any recommendation made by Parent), regarding, and participate in, but not control, the defense or settlement of any such legal proceeding. The Company shall not agree to any such compromise or settlement, or file any supplemental disclosure to moot or otherwise address the claims in any legal proceeding, without Parent’s prior written consent.

Delisting. Each of the parties has agreed to reasonably cooperate with the other parties in taking, or causing to be taken, all actions necessary to delist the Shares from Nasdaq and terminate its registration under the Exchange Act, provided that such delisting and termination will not be effective until after the Effective Time. If

61

the Surviving Corporation is reasonably likely to be required to file any reports in accordance with the Exchange Act prior to the first business day that is at least ten days after the Closing Date, the Company will deliver to Parent at least five business days prior to the Closing a substantially final draft of any such reports, which shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statement made therein, in the light of the circumstances under which they were made, not misleading and shall comply in all material respects with the provisions of applicable laws.

14d-10 Matters. The Company has agreed that, prior to the Acceptance Time, the compensation committee of the Company Board will have taken all steps as may be necessary to (a) approve as an “employment compensation, severance or other employee benefit arrangement” within the meaning of Rule 14d-10(d)(1) under the Exchange Act, any agreement, plan, program, arrangement or understanding entered into or established by the Company or its subsidiaries with or on behalf of its officers, directors or employees, in each case, at or prior to the Expiration Time, including any amendment or modification thereto, and (b) satisfy the requirements of the non-exclusive safe harbor under Rule 14d-10(d) under the Exchange Act with respect to such agreement, plan, program, arrangement or understanding.

Tax Cooperation. Prior to the Closing Date, the parties and their agents and affiliates shall cooperate in good faith with each other regarding the tax treatment of and reporting with respect to the CVR Agreement and payments in the form of or with respect to any CVR.

FIRPTA. At or prior to Closing, the Company shall deliver to Parent a certificate issued by the Company conforming to the requirements of U.S. Treasury Regulations Section 1.1445-2(c)(3), together with an executed form of notice to the Internal Revenue Service in accordance with the provisions of U.S. Treasury Regulations Section 1.897-2(h)(2), in each case in form and substance reasonably satisfactory to Parent; provided, notwithstanding anything to the contrary in the Merger Agreement¸ that if the Company fails to deliver such a certificate, Parent’s sole and exclusive remedy is to deduct and withhold from any amounts payable pursuant to the Merger Agreement and the CVR Agreement as required by tax laws pursuant to the applicable terms of the Merger Agreement.

Notifications. The Company shall deliver prompt notice to Parent of (i) the occurrence or non-occurrence of any event the occurrence or non-occurrence of which would cause any of the Offer Conditions or the conditions to the Merger to not be satisfied (or not be capable of being satisfied as of the Expiration Time (with respect to the Offer Conditions) or as of the Effective Time (with respect to the conditions to the Merger)), and (ii) any written communication from any person alleging that the consent of such person is or may be required in connection with the Offer or the Merger.

Resignations. The Company shall use its reasonable best efforts to obtain and provide to Parent, on or prior to the Closing Date, to the extent requested in writing by Parent at least ten business days prior to the Closing Date, resignation letters, effective as of and contingent upon the Effective Time, from each of the directors and officers of the Company as requested by Parent, resigning from such position as a director or officer of the Company.

Pursuant to the Merger Agreement, the respective obligations of the Company, Parent and Merger Sub to effect the Merger are subject to the satisfaction of the following conditions at or prior to the Effective Time, any and all of which may be waived in whole or in part by mutual consent of Parent, Merger Sub and the Company, as the case may be, to the extent permitted by applicable law:

64

Effect of Termination. If the Merger Agreement is properly and validly terminated, the Merger Agreement will be of no further force or effect (other than the confidentiality provision and certain other specified provisions therein) and, subject to the payment of the Company Termination Fee, if applicable, there will be no liability of any party or parties to the Merger Agreement or the respective directors, officers, employees, affiliates, agents or other representatives of such party or parties, or the Parent Related Parties or the Company, any affiliates thereof, any direct or indirect stockholder, partner, manager or other equity or security holder of the Company or any affiliate thereof or any representative of any of the foregoing (the “Company Related Parties”) to the other party or parties to the Merger Agreement, except in the case of certain exceptions set forth in the Merger Agreement; provided that, subject to certain exceptions set forth in the Merger Agreement, no party will be relieved from any liability or damage resulting from any actual and intentional fraud or Willful Breach (as defined below) of the Merger Agreement that occurs prior to such termination (which liability or damages the parties agree will not be limited to reimbursement of out of pocket fees, costs or expenses incurred in connection with the Transactions contemplated by the Merger Agreement, and such party will have the right to seek damages based on loss of the economic benefit of the Transactions contemplated by the Merger Agreement to the Company and the Company stockholders). The parties further agreed, subject to and without limiting certain specified provisions in the Merger Agreement, to the extent Parent or Merger Sub is required to pay damages in connection with the termination of the Merger Agreement that exceeds the Company’s expenses or out-of-pocket costs incurred in connection with the Merger Agreement and the Transactions contemplated thereby, including any disputes related thereto, such excess represents an amount of damages payable in respect of losses suffered by the Company stockholders as of the date on which the Merger Agreement is terminated in respect of the Shares.

“Willful Breach” means a material breach of the Merger Agreement that is the consequence of an act or omission by the breaching party with the actual knowledge that the taking of such act or failure to take such action would cause or constitute a material breach of the Merger Agreement.

Company Termination Fee. The Company shall pay to Parent $1,500,000 (the “Company Termination Fee”), by wire transfer of immediately available funds to an account or accounts designated in writing by Parent, in the event that:

(i) (A) the Merger Agreement is terminated by Parent or the Company pursuant to a Termination Date Termination or an Expired Offer Termination or by Parent pursuant to a Company Breach Termination; (B) following the execution and delivery of the Merger Agreement and prior to such termination, (x) an Acquisition Proposal (whether or not conditional and whether or not withdrawn) shall have been publicly announced or shall have become publicly disclosed and, in either case, shall not have been publicly withdrawn or otherwise publicly abandoned without qualification at least three business days prior to the Expiration Time or (y) an Acquisition Proposal (whether or not conditional and whether or not withdrawn) shall have been made to the Company Board or senior management of the Company and, in either case, shall not have been withdrawn or otherwise abandoned without qualification at least three business days prior to the Expiration Time; and (C) within 12 months following such termination of the Merger Agreement, the Company enters into a definitive agreement with any third party with respect to an Acquisition Proposal or consummates an Acquisition Proposal, in which case the Company Termination Fee shall be payable substantially concurrently with the consummation of the Acquisition Transaction, provided that any amount previously paid to Parent pursuant to the expense

65

reimbursement provision of the Merger Agreement shall be credited towards the payment of the Company Termination Fee. For purposes of this paragraph, all references to “20%” and “80%” in the definition of “Acquisition Proposal” or “Acquisition Transaction” described above under “- No Solicitation” will each be deemed to be references to “50%”;

(ii) the Merger Agreement is terminated by the Company pursuant to a Superior Offer Termination, in which case the Company Termination Fee shall be payable concurrently with or prior to (and in any event as a condition of) such termination; or

(iii) the Merger Agreement is terminated by Parent pursuant to a Change in Recommendation Termination, in which case the Company Termination Fee shall be payable within two business days after such termination.

Parent Termination Fee. Subject to the provisions described in the “- Termination Fee as Exclusive Remedy” subsection, Parent shall pay the Parent Termination Fee owing to the Company, by wire transfer of immediately available funds (which the Company has directed Parent to pay on the Company’s behalf in full and final satisfaction thereof, and which Parent has agreed to pay at the Company’s direction and on its behalf, to the Hercules Capital, Inc., a Maryland corporation (“Hercules”), account set forth in the applicable section of the Company Disclosure Letter) in the event that the Merger Agreement is terminated by the Company or Parent after the First Extended Termination Date pursuant to a Termination Date Termination and at the time of such termination all of the Offer Conditions shall have been satisfied or waived (other than (i) those conditions that by their terms are to be satisfied at the Expiration Time, but subject to such conditions being able to be satisfied if the Expiration Time were to occur at such time, and (ii) the Regulatory Approvals Condition and the No Injunction Condition (only to the extent the applicable law or order relates to an antitrust law)). Hercules is intended to be a third-party beneficiary of the provision described in this paragraph, subject to the terms and conditions of the Merger Agreement.

“Parent Termination Fee” means with respect to the fee payable pursuant to the provisions described in the immediately preceding paragraph with respect to a termination of the Merger Agreement pursuant to a Termination Date Termination that occurs (i) after the First Extended Termination Date but prior to or on the Second Extended Termination Date, (a) $1.0 million plus (b) the Parent Termination Fee Increase Amount (if any), or (ii) after the Second Extended Termination Date, (a) $2.0 million plus (b) the Parent Termination Fee Increase Amount (if any).

“Parent Termination Fee Increase Amount” means any amount elected by Parent, in its sole discretion, in a written notice delivered by Parent to the Company (with copy to Hercules) at any time, or from time to time. Any such notice will specify the aggregate Parent Termination Fee Increase Amount as in effect immediately prior to and upon such election. For the avoidance of doubt, subsequent notices may increase but not decrease such amount. As of the date of the Merger Agreement, the Parent Termination Fee Increase Amount was $0.

Single Payment Only. In no event shall the Company be required to pay the Company Termination Fee on more than one occasion, whether or not the Company Termination Fee may be payable under more than one provision of the Merger Agreement at the same or at different times and the occurrence of different events. In no event will Parent be required to pay the Parent Termination Fee on more than one occasion, whether or not the Parent Termination Fee may be payable under more than one provision of the Merger Agreement at the same or at different times and the occurrence of different events.

Expense Reimbursement. If the Merger Agreement is terminated by (i) Parent pursuant to a Company Breach Termination or (y) either Parent or the Company pursuant to a Termination Date Termination or an Expired Offer Termination, provided that at the time of the Company’s termination pursuant to a Termination Date Termination or an Expired Offer Termination, the Merger Agreement is terminable by Parent pursuant to a

66

Termination Date Termination or an Expired Offer Termination, and, in the case of clause (y), both the Regulatory Approvals Condition and the No Injunction Condition were satisfied (other than those conditions that by their terms are to be satisfied at the Expiration Time, but subject to such conditions being able to be satisfied if the Expiration Time were to occur at such time) or validly waived at the Expiration Time, the Company shall pay to Parent by wire transfer of immediately available funds to an account or accounts designated in writing by Parent, an amount equal to Parent and Merger Sub’s costs and expenses (including attorneys’ fees and expenses) actually incurred by Parent or Merger Sub on or prior to the termination of the Merger Agreement (the “Expense Reimbursement Amount”), up to an amount not to exceed $300,000 in the aggregate.

Termination Fee as Exclusive Remedy. Subject to the terms of the Merger Agreement, in the event the Merger Agreement is terminated under the circumstances in which the Company Termination Fee is payable pursuant to the terms of the Merger Agreement and is accepted by Parent: the payment by the Company of the Company Termination Fee (including, in each case, any additional amount payable pursuant to the provision described in this paragraph) and the amount payable pursuant to the provision described in the “- Expense Reimbursement” subsection (including, in each case, any additional amount payable pursuant to the provision described in this paragraph), if applicable, will be the sole and exclusive remedy of Parent, Merger Sub and the Guarantors, each of their respective affiliates, each of the direct and indirect stockholders, partners, managers or other equity or security holders of Parent, Merger Sub, the Guarantors or any of their respective affiliates, and any representative of any of the foregoing (each, a “Parent Related Party”) arising out of the Merger Agreement or any of the Transactions contemplated thereby, and any loss suffered as a result of the failure of the Offer, the Merger or any other transactions contemplated by the Merger Agreement to be consummated. If the Company fails to timely pay any amount due pursuant to the fees and expenses provisions of the Merger Agreement, and, in order to obtain the payment, Parent commences a legal proceeding which results in a judgment against the Company for the payment set forth in the fees and expenses provisions of the Merger Agreement, the Company shall pay Parent its reasonable and documented costs and expenses (including reasonable and documented attorneys’ fees) incurred in prosecuting such legal proceeding, together with interest on such amount at the prime rate as published in The Wall Street Journal in effect on the date such payment was required to be made through the date such payment was actually received. Notwithstanding the foregoing, payment of the Company Termination Fee or the Expense Reimbursement Amount will not relieve the Company from liability for any actual and intentional fraud or Willful Breach.

Subject to the terms of the Merger Agreement, in the event the Merger Agreement is terminated under the circumstances in which the Parent Termination Fee is payable pursuant to the terms thereof and is accepted by the Company, the payment by Parent of the Parent Termination Fee pursuant to the provisions described in the “- Parent Termination Fee” subsection (including, in each case, any additional amount payable pursuant to the provision described in the immediately preceding paragraph), if applicable, shall be the sole and exclusive remedy of the Company and each other Company Related Party arising out of the Merger Agreement or any of the Transactions contemplated thereby, and any loss suffered as a result of the failure of the Offer, the Merger or any other Transactions contemplated thereby to be consummated. In the event the Merger Agreement is terminated under the circumstances in which the Parent Termination Fee would otherwise be payable pursuant to the terms thereof, the Company shall have the right, subject to Hercules’ consent, to elect to pursue a claim for monetary damages in connection with Parent’s or Merger Sub’s actual and intentional fraud or Willful Breach of any of Parent’s or Merger Sub’s representations, warranties, covenants or other agreements set forth in the Merger Agreement rather than accept payment of the Parent Termination Fee. If Parent fails to timely pay any amount due pursuant to the fees and expenses provision of the Merger Agreement, and, in order to obtain the payment, the Company commences a legal proceeding which results in a judgment against Parent for the payment set forth in the fees and expenses provision of the Merger Agreement, Parent shall pay to the Company its reasonable and documented costs and expenses (including reasonable and documented attorneys’ fees) incurred in prosecuting such legal proceeding, together with interest on such amount at the prime rate as published in The Wall Street Journal in effect on the date such payment was required to be made through the date such payment was actually received, up to an amount not to exceed $300,000 in the aggregate.

67

The sole and exclusive remedy, whether at law, in equity, in contract, in tort or otherwise, of the Company, the Company Related Parties and any other person against Parent, Merger Sub or any Parent Related Party for any breach (whether willful (including a Willful Breach), intentional, unintentional or otherwise), loss, liability or damage in connection with, relating to or arising out of (A) the Merger Agreement, the Limited Guarantees, the Equity Commitment Letters and any certificates, instruments or other documents delivered pursuant to such agreements (collectively, the “Transaction Documents”) or any of the other agreements, instruments, and documents contemplated by the Merger Agreement or the Transaction Documents or executed in connection with the Merger Agreement or the Transaction Documents and the transactions contemplated by the Merger Agreement or the Transaction Documents, (B) the Transactions contemplated by the Merger Agreement or any other Transaction Document, including the Offer, the Merger and the Financing, (C) the negotiation, execution or performance or non-performance of any of the foregoing, (D) the failure of the consummation of the Offer, the Merger or any of the other transactions contemplated by the Merger Agreement or the other Transaction Documents to occur (including the funding of the Financing and, in any case, whether willfully, intentionally, unintentionally or otherwise), or the termination of the Merger Agreement or any other Transaction Document or any matter forming the basis for such termination, (E) any breach (or threatened or alleged breach) of, or failure (or threatened or alleged failure) to perform under, the Merger Agreement, the Transaction Documents or any certificate or other document executed or delivered in connection herewith or therewith or (F) any oral or written representation made or alleged to have been made in connection with any of the foregoing (collectively, the “Transaction Claims”), shall be the Company’s right (i) to specific performance if and to the extent expressly permitted by Section 10.8 of the Merger Agreement, (ii) to terminate the Merger Agreement pursuant to a Termination Date Termination, subject to the terms of the provisions described in the “- Parent Termination Fee” subsection, and receive payment of the Parent Termination Fee, if applicable, plus any amount due under the provision described in the second paragraph of the “- Termination Fee as Exclusive Remedy” subsection, if applicable, or (iii) subject to the provision described in the second paragraph of the “- Termination Fee as Exclusive Remedy” subsection and the last sentence of this paragraph, to seek recovery of damages incurred or suffered as a result of Parent’s or Merger Sub’s actual and intentional fraud or Willful Breach of any of Parent’s or Merger Sub’s representations, warranties, covenants or other agreements set forth in the Merger Agreement, and, in each case, Parent and Merger Sub will not (nor will any other Parent Related Party) have any other liability or obligation to the Company or any other Company Related Party in connection with, relating to or arising out of any of the Transaction Claims. For the avoidance of doubt, in the event that the Parent Termination Fee is paid to and accepted by the Company in accordance with the provisions described in the “- Parent Termination Fee” subsection, then the only other remedies, whether at law, in equity, in contract, in tort or otherwise, of the Company and the Company Related Parties against Parent or the Parent Related Parties for any breach (whether willful (including a Willful Breach), intentional, unintentional or otherwise), loss, liability or damage in connection with, relating to or arising out of any of the Transaction Claims will be to receive the amounts contemplated by the provision described in the second paragraph of the “- Termination Fee as Exclusive Remedy” subsection, if any, subject to the terms thereof. The maximum aggregate liability, whether at law, in equity, in contract, in tort or otherwise and with respect to any other payment in connection with any Transaction Document or otherwise, of the Parent Related Parties collectively (including with respect to the Parent Termination Fee, monetary damages for fraud or breach, whether willful (including Willful Breach), intentional, unintentional or otherwise) relating to or arising out of any of the Transaction Claims, will not exceed (i) in the event the Parent Termination Fee is payable, the sum of the Parent Termination Fee plus any additional amount, if any, due under the provision described in the second paragraph of the “- Termination Fee as Exclusive Remedy” subsection, and (ii) under any other circumstances, an amount equal to $10,000,000 (ten million dollars); provided that the foregoing limitation shall not relieve PJ Carlin & Co., LLC (“PJ Carlin”) from any liability for any breaches of the Confidentiality Agreement.

Remedies. Except as otherwise provided in the Merger Agreement and subject to the terms and conditions set forth therein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred by the Merger Agreement, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. Parent, Merger Sub and the Company have agreed that irreparable damage would occur in the event that any provision of the

68

Merger Agreement was not performed in accordance with its specific terms or were otherwise breached, and that money damages or other legal remedies would not be an adequate remedy for any such damages. Accordingly, the parties have acknowledged and agreed, subject to the terms of the Merger Agreement, that in the event of any breach or threatened breach by the Company, on the one hand, or Parent and/or Merger Sub, on the other hand, of any of their respective covenants or obligations set forth in the Merger Agreement, the Company, on the one hand, and Parent and Merger Sub, on the other hand, shall be entitled (without proof of actual damages or otherwise or posting or securing any bond or other security), in addition to any other remedy to which they are entitled to under law or equity, to an injunction or injunctions to prevent or restrain breaches or threatened breaches of the Merger Agreement, by the other party (as applicable), and to specifically enforce the terms and provisions of the Merger Agreement to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of the other under the Merger Agreement. The Company, on the one hand, and Parent and Merger Sub, on the other hand, have agreed not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches or threatened breaches of the Merger Agreement by such party (or parties), and to specifically enforce the terms and provisions of the Merger Agreement to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of such party (or parties) under the Merger Agreement. Any party’s pursuit of any injunction or specific performance at any time will not be deemed an election of remedies or waiver of the right to pursue any other right or remedy to which such party may be entitled, including the right to pursue remedies for liabilities or damages incurred or suffered by a party in the case of a breach of the Merger Agreement involving Willful Breach or fraud; provided, however, that in no event shall Parent or Merger Sub be entitled to both the payment of the Company Termination Fee or the Expense Reimbursement Amount, on the one hand, and specific performance requiring the consummation of the Offer and/or the Merger, on the other hand.

Although the Company may pursue both a grant of specific performance to the extent permitted by the Merger Agreement and the Parent Termination Fee and/or monetary damages pursuant to and in accordance with the Merger Agreement, under no circumstances will the Company, directly or indirectly, be permitted or entitled to receive (x) both (i) a grant of specific performance to cause the Financing to be funded (whether under the Merger Agreement or the Equity Commitment Letters) or other equitable relief, on the one hand, and (ii) payment of any monetary damages or the Parent Termination Fee, on the other hand; or (y) both (i) payment of any monetary damages, on the one hand, and (ii) payment of the Parent Termination Fee, on the other hand.

In no event will the Company or any Company Related Party be entitled to enforce or seek to enforce specifically Parent’s or Merger Sub’s obligation to cause all or any portion of the Financing to be funded (whether under the Merger Agreement or the Equity Commitment Letters) or cause Parent or Merger Sub to consummate the Offer and/or the Merger (including to pay all or any portion of the Offer Price and/or the Merger Consideration) unless and only if: (i) (A) with respect to the Offer and payment of the Offer Price and the Financing related thereto, all Offer Conditions were satisfied (other than those conditions that by their terms are to be satisfied at the Expiration Time, but subject to such conditions being able to be satisfied if the Expiration Time were to occur at such time) or validly waived at the Expiration Time or (B) with respect to the Merger, the payment of the Merger Consideration and the Financing related thereto, the conditions to the Merger were satisfied or validly waived at the Closing (other than those conditions that by their terms are to be satisfied at the Effective Time, but subject to such conditions being able to be satisfied if the Effective Time were to occur at such time), (ii) Parent and Merger Sub failed to (A) consummate the Offer by the date they are required to do so pursuant to the Merger Agreement or (B) consummate the Merger by the date they are required to do so pursuant to the Merger Agreement, (iii) the Company irrevocably confirmed in writing to Parent that if specific performance is granted and the Financing is funded, then the Acceptance Time and the Closing will occur substantially simultaneously with the drawdown of the Financing (and the Company has not withdrawn, modified or conditioned such confirmation) and the Company is prepared, willing and able to effect the Closing and the other transactions contemplated thereunder, and (iv) Parent and Merger Sub fail to complete the Closing within three business days after delivery of such irrevocable written confirmation. Notwithstanding anything in the Merger Agreement to the contrary, the Company may only enforce the obligations of (w) the SK Capital Guarantors under the SK Capital Limited Guarantee (as defined herein) if it concurrently enforces the obligations of the Carlyle Guarantor pursuant to the Carlyle Limited

69

Guarantee to the extent that the Carlyle Guarantor has not performed its obligations under the Carlyle Limited Guarantee, (x) the Carlyle Guarantor under the Carlyle Limited Guarantee if it concurrently enforces the obligations of the SK Capital Guarantors pursuant to the SK Capital Limited Guarantee to the extent that the SK Capital Guarantors have not performed their obligations under the SK Capital Limited Guarantee, (y) the SK Capital Guarantors under the SK Capital Equity Commitment Letter if it concurrently enforces the obligations of the Carlyle Guarantor pursuant to the Carlyle Equity Commitment Letter to the extent that the Carlyle Guarantor has not performed its obligations under the Carlyle Limited Guarantee, and (z) the Carlyle Guarantor under the Carlyle Equity Commitment Letter if it concurrently enforces the obligations of the SK Capital Guarantors pursuant to the SK Capital Equity Commitment Letter to the extent the SK Capital Guarantors have not performed their obligations under the SK Capital Limited Guarantee.

Fees and Expenses. Except in limited circumstances expressly specified in the Merger Agreement, all fees and expenses incurred in connection with the Merger Agreement and the Transactions contemplated thereby shall be paid by the party or parties, as applicable, incurring such expenses whether or not the Offer and the Merger are consummated.

Governing Law. The Merger Agreement is governed by and will be construed and enforced in accordance with the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof.

The foregoing description of the Merger Agreement is a summary and is qualified by reference to the full text of the form of the Merger Agreement, which is filed as Exhibit (d)(1) of the Schedule TO and is incorporated herein by reference.

Other Agreements

CVR Agreement

Pursuant to the CVR Agreement to be entered into between Parent, the Rights Agent and, solely for certain purposes, the Surviving Corporation, each CVR will represent a contractual contingent value right that entitles the holder thereof the right to receive the Milestone Payment, subject to any applicable withholding taxes and without interest, payable upon the achievement of $600 million in Net Sales of the Existing Products in any consecutive twelve calendar month period (provided that such consecutive twelve calendar month period may begin and end in separate years) ending on or prior to December 31, 2027 (the “Milestone Outside Date”).

Parent shall use Commercially Reasonable Efforts (as defined below) to achieve the Milestone prior to the Milestone Outside Date. The use of Commercially Reasonable Efforts allows Parent to take into account a variety of factors when determining the efforts it is obligated to devote to achieving the Milestone. Because the Commercially Reasonable Efforts obligation in the CVR Agreement is not to an absolute obligation to achieve the Milestone, actions or omissions by Parent that may be permitted under the Commercially Reasonable Efforts standard may have an adverse effect on the likelihood that the Milestone will be achieved and consequently on the value, if any, of the CVRs. Use of Commercially Reasonable Efforts does not guarantee that Parent will achieve the Milestone by a specific date or at all.

“Commercially Reasonable Efforts” is defined as a level of efforts that is consistent with the level of efforts, including expenditure of resources, that a bio-pharmaceutical company of comparable size and resources to Parent and its controlled affiliates would typically devote to marketing and selling a product of similar commercial value, actual or anticipated profitability and market potential and at a similar stage of product lifecycle, taking into account all relevant factors, which may include the existence of other third party competitive products in the market place or under development, safety and efficacy, tolerability, product profile, risk profile, manufacturing and supply chain, anticipated or actual market conditions and market position, probability of success, actual or likely pricing and reimbursement rates, cost of goods and other costs (excluding

70

any payments under the CVR Agreement), labeling, pricing reimbursement, the likelihood of obtaining regulatory approval and pricing or reimbursement approval, the benefit of continuing development relative to the benefit of other products being developed by Parent, alternative products in the market and under development, the patent coverage, expiration, term extension and other proprietary position of the product, the applicable regulatory environment, and other factors, including technical, commercial, legal, regulatory, marketing, scientific, medical and/or return-on-investment factors, based on conditions then prevailing. It is understood that product potential may change from time to time based upon changing technical, commercial, legal, regulatory, marketing, scientific, medical and/or return-on-investment considerations.

If the Milestone is achieved on or prior to the Milestone Outside Date, then as promptly as reasonably practicable (and in any event no later than 60 days) after the last day of the calendar month in which the Milestone is achieved (a “Milestone Payment Date”), Parent shall deliver to the Rights Agent (i) written notice (a “Milestone Achievement Notice”) indicating that the Milestone has been achieved, which Milestone Achievement Notice shall be accompanied by an officer’s certificate certifying that the Milestone was achieved prior to the Milestone Outside Date, (ii) any letter of instruction reasonably required by the Rights Agent and (iii) cash, by wire transfer of immediately available funds to an account specified by the Rights Agent, in an amount equal to the aggregate amount necessary to pay the Milestone Payment to all holders pursuant to the terms of the CVR Agreement other than holders of CVRs granted with respect to Company RSUs and Company PSUs (collectively, “Equity Award Holders”) (with respect to which any such amounts payable shall be retained by Parent for payment pursuant to the CVR Agreement).

In the event that Parent delivers a Milestone Achievement Notice, with respect to any Milestone Payment that is payable to Equity Award Holders, Parent shall, as soon as reasonably practicable following the Milestone Payment Date (but in any event no later than the next regularly scheduled payroll date that is at least five business days following the date of the delivery of the Milestone Achievement Notice, and in all events no later than the date that is 30 days following the date of the delivery of the Milestone Achievement Notice or, if earlier, to the extent required to be exempt from Section 409A of the Code, the last date within the applicable “short-term deferral” period as set forth in Treasury Regulation Section 1.409A-1(b)(4)), pay, or shall cause the Surviving Corporation or an Affiliate thereof to pay through Parent’s, the Company’s or such Affiliate’s payroll system or accounts payable systems, as applicable (and subject to any applicable withholding Taxes pursuant to the Merger Agreement), the Milestone Payment Amount (defined as, for a given holder of CVRs, the product of (a) the Milestone Payment and (b) the number of CVRs held by such holder as reflected on the CVR Register as of the close of business on the date of the Milestone Achievement Notice relating to achievement of the Milestone) to each such Equity Award Holder in accordance with the Merger Agreement. Notwithstanding anything in the CVR Agreement to the contrary, it is the intent of the parties that the Milestone be deemed to constitute a substantial risk of forfeiture within the meaning of Section 409A of the Code and that the Milestone Payment Amount to each such Equity Award Holder be exempt from Section 409A of the Code; provided, however, to the extent necessary to comply with Section 409A of the Code, such Milestone Payment Amount will be paid in compliance with Treasury Regulation Section 1.409A-3(i)(5)(iv)(A).

Within 60 days following the end of each calendar year that begins after the date of the CVR Agreement and prior to the Milestone Outside Date in which the Milestone has not been achieved, Parent will deliver to the Rights Agent a certificate (each certificate delivered following the end of a calendar year that ends prior to the Milestone Outside Date, a “Reporting Certificate,” the certificate delivered following the end of the calendar year ending on the Milestone Outside Date, a “Milestone Non-Achievement Notice”) certifying that the holders of the CVRs are not entitled to receive the Milestone Payment (i) in the case of a Reporting Certificate, with respect to such calendar year or (ii) in the case of the Milestone Non-Achievement Notice, at any time, and, in each case in the event a Reporting Certificate or Milestone Non-Achievement Notice is delivered, setting forth in reasonable detail, Parent’s calculation of the Net Sales as of the end of such calendar year and a breakdown of Net Sales in each month for each of the Existing Products in such calendar year, together with reasonable supporting documentation for such calculations. In the event a Milestone Non-Achievement Notice is delivered, such notice shall be accompanied by an officer’s certificate certifying that the Milestone was not achieved prior

71

to the Milestone Outside Date, and, accordingly, no Milestone Payment Amount shall be payable to the holders of the CVRs.

In the event a Milestone Non-Achievement Notice has been delivered by Parent to the Rights Agent indicating that the Milestone has not been achieved prior to the Milestone Outside Date, the holders of at least 30% of the outstanding CVRs (the “Acting Holders”) may object to any determination or calculation set forth in any Reporting Certificate and/or the Milestone Non-Achievement Notice by delivery of a written notice thereof to Parent setting forth in reasonable detail such objection, together with reasonable supporting documentation (an “Objection Notice”), within 60 days following the Rights Agent’s receipt of the Milestone Non-Achievement Notice from Parent (such 60-day period, the “Objection Period”). If the Acting Holders do not submit an Objection Notice during the Objection Period, Parent’s determination that the Milestone was not achieved prior to the Milestone Outside Date, as reflected in the applicable Reporting Certificates and/or the Milestone Non-Achievement Notice, shall be final and binding on all parties. Any determination, calculation or other item set forth in a Reporting Certificate or Milestone Non-Achievement Notice that is not disputed in an Objection Notice shall be final and binding on all parties. If the Acting Holders timely deliver to Parent an Objection Notice, Parent and the Acting Holders shall attempt in good faith to resolve such matters within 30 days after receipt of such Objection Notice by Parent, and if unable to do so, Parent and the Acting Holders (on behalf of the holders of the CVRs) shall jointly engage the financial expert appointed pursuant to the CVR Agreement (the “Financial Expert”) and each of Parent and the holders of the CVRs shall deposit into escrow 50% of the Financial Expert’s estimated engagement fees and expenses. In connection with any Objection Notice, Parent shall provide the Financial Expert with reasonable access during normal business hours and upon reasonable advance written request to the books and records of the Selling Entities (as defined in the CVR Agreement) to the extent necessary to verify (i) whether the Milestone has been achieved or (ii) Parent’s calculation of the Milestone Payment Amount. Further, subject to not less than five business days advance written notice from the Acting Holders, Parent shall permit the Financial Expert to have reasonable access during normal business hours to the books and records of the Selling Entities as may be reasonably necessary to verify the calculation of the Milestone Payment Amount or the calculation of the amount of Net Sales in connection therewith. The Financial Expert will, under the terms of its engagement, be appointed to serve as an expert and not an arbitrator, and be required to render its written decision with respect to such disputed items and amounts within 30 business days from the date of such appointment. The Financial Expert shall deliver to the parties a written report setting forth its adjustments, if any, to the amount of Net Sales and Milestone Payment Amount based on the Financial Expert’s determination, solely with respect to the disputed items and amounts in accordance with the CVR Agreement, and such report shall include the calculations supporting such adjustments; provided, that for each item set forth in the Objection Notice, the Financial Expert shall assign a value for each such item no greater than the higher amount, and no less than the lower amount, calculated or set forth in any applicable Reporting Certificate, the Milestone Non-Achievement Notice or the Objection Notice with respect to such item, as the case may be. The Financial Expert shall have no power to amend or supplement the terms of the CVR Agreement or the Merger Agreement or act as arbitrator. The Financial Expert’s report shall be final, conclusive, and binding on the parties and the holders of the CVRs, shall not be subject to further review by any court, and no party or holder of the CVRs nor any of their respective affiliates or representatives may seek recourse to any courts, other tribunals or otherwise, other than to enforce the determination of the Financial Expert. If the Financial Expert determines that the Milestone Payment Amount is not owed to the holders of the CVRs, the Acting Holders shall be responsible for all fees and expenses of the Financial Expert and all amounts deposited into escrow by Parent with respect thereto shall be promptly returned to Parent. If the Financial Expert determines that the Milestone Payment Amount is owed to the holders of the CVRs, Parent shall be responsible for all fees and expenses of the Financial Expert and amounts deposited into escrow by the holders of the CVRs with respect thereto shall be promptly returned to the holders of the CVRs. The aforementioned rights may not be exercised on more than one occasion in the aggregate by the holders of the CVRs.

The CVRs will not be transferable except (i) upon death of a holder of a CVR by will or intestacy; (ii) by instrument to an inter vivos or testamentary trust in which the CVRs are passed to beneficiaries of the holder of a CVR upon the death of such holder; (iii) pursuant to a court order (including in connection with a bankruptcy or

72

liquidation); (iv) by operation of law (including by consolidation or merger) or without consideration in connection with the dissolution, liquidation or termination of any corporation, limited liability company, partnership or other entity; (v) in the case of CVRs held in book-entry or other similar nominee form, from a nominee to a beneficial owner and, if applicable, through an intermediary, to the extent allowable by DTC. In addition, CVRs may be abandoned by the holder by transfer to Parent without consideration therefor. Parent or any of its affiliates may offer to acquire or acquire any CVRs for consideration from any holder of a CVR, in private transactions or otherwise, in its sole discretion. Any CVRs acquired by Parent or any of its affiliates will be automatically deemed extinguished and no longer outstanding.

The rights to payment described above are solely contractual rights governed by the terms and conditions of the CVR Agreement. The CVRs will not be evidenced by a certificate or other instrument, will not have any voting or dividend rights and will not represent any equity or ownership interest in Parent, Merger Sub or the Company and will not be owed any fiduciary or similar duties by Parent, its affiliates or any of their respective directors or officers. The CVRs will not be registered or listed for trading. No interest will accrue or be payable in respect of any of the amounts that may become payable on the CVRs. There can be no assurance that the Milestone will be achieved or that the Milestone Payment will be made.

All funds received by the Rights Agent under the CVR Agreement that are to be distributed or applied by the Rights Agent in the performance of its services thereunder (the “Funds”) shall be held by the Rights Agent as agent for Parent and deposited in one or more segregated bank accounts to be maintained by the Rights Agent in its name as agent for Parent. The Funds shall not be used for any purpose other than to pay the Milestone Payment under the CVR Agreement. The Funds shall be invested by the Rights Agent as directed by Parent, subject to certain requirements set forth in the CVR Agreement. To the extent that there are losses with respect to such investments, or the Funds diminish for other reasons below the level required to make prompt payment of the Milestone Payment due under the CVR Agreement, Parent shall promptly replace or restore the portion of the Funds lost through investments or other events so as to ensure that the Funds are maintained at a level sufficient to make such payment. Any interest and other income resulting from such investment (if any) in excess of the amounts payable pursuant to the CVR Agreement shall be for the benefit of Parent and promptly returned to Parent.

The Rights Agent will keep a register for the purpose of (i) identifying the holders of CVRs and (ii) registering CVRs and permitted transfers thereof. The register will initially show one position for Cede & Co. representing all the Shares held by DTC on behalf of the street holders of the Shares as of immediately prior to the Effective Time. The Rights Agent will have no responsibility whatsoever directly to the street name holders with respect to transfers of CVRs unless and until such CVRs are transferred into the name of such street name holders in accordance with the terms of the CVR Agreement. With respect to any payments to be made under the CVR Agreement, the Rights Agent will accomplish the payment to any former street name holders of the Shares by sending one lump payment to DTC. The Rights Agent will have no responsibilities whatsoever with regard to the distribution of payments by DTC to such street name holders. Upon request of any holder of CVRs and at its sole cost, the Rights Agent will make available to such holder a list of the other holders of CVRs, the number of CVRs held by such holder and the contact information maintained by the Rights Agent with respect to each holder of the CVRs. Parent will furnish or cause to be furnished to the Rights Agent (a) the names and addresses of the holders of the CVRs within 30 business days after the Effective Time, in such form as Parent receives from the Company’s transfer agent and (b) in the case of Equity Award Holders, the name and address of such holders as set forth in the books and records of the Company at the Effective Time and in accordance with the terms of the Merger Agreement.

Parent may not, without the consent of the Acting Holders, amend the terms of the CVR Agreement other than (i) to provide for a successor to Parent, (ii) to cure any ambiguities, correct or supplement any provisions of the CVR Agreement that may be defective or inconsistent or make any other provisions with respect to matters or questions arising under the CVR Agreement (if such provisions do not adversely affect the interests of the holders of the CVRs), (iii) amendments as may be necessary or appropriate to ensure that the CVRs are not

73

subject to registration under the Securities Act or the Exchange Act or any applicable state securities or “blue sky” laws, (iv) as may be necessary to comply with or be exempt from the requirements of Section 409A of the Code; (v) to provide for a successor rights agent, (vi) to evidence the assignment of the CVR Agreement by Parent as provided in the CVR Agreement; and/or (vii) any other amendments for the purpose of adding, eliminating or changing any provisions of the CVR Agreement, unless such addition, elimination or change is adverse to the interests of the holders of the CVRs.

The Rights Agent may in its discretion or upon the written request of the Acting Holders proceed to and shall be entitled and empowered to protect and enforce the rights of the holders of the CVRs under the CVR Agreement by such appropriate judicial proceedings as the Rights Agent shall deem most effectual to protect and enforce any such rights. Except for the rights of the Rights Agent set forth in the CVR Agreement, the Acting Holders will have the sole right, on behalf of all holders of the CVRs, by virtue of or under any provision of the CVR Agreement, to institute any action or proceeding with respect to the CVR Agreement, and no individual holder of a CVR or other group of holders of the CVRs will be entitled to exercise such rights.

The foregoing description of the CVR Agreement is a summary and is qualified by reference to the full text of the form of the CVR Agreement, which is filed as Exhibit (d)(2) of the Schedule TO and is incorporated herein by reference.

12. Purpose of the Offer; Plans for the Company

Purpose of the Offer

The purpose of the Offer is for Parent, through Merger Sub, to acquire control of, and the entire equity interest in, the Company. The Offer, as the first step in the acquisition of the Company, is intended to facilitate the acquisition of all outstanding Shares. The purpose of the Merger is to acquire all outstanding Shares not tendered and purchased pursuant to the Offer. If the Offer is consummated, Merger Sub intends to complete the Merger as soon as practicable thereafter.

The Company Board has unanimously (i) determined that the Merger Agreement and the Transactions contemplated thereby, including the Offer and the Merger, are advisable, fair to and in the best interests of the Company and its stockholders, and declared it advisable for the Company to enter into the Merger Agreement and consummate the Transactions contemplated therein, (ii) approved and declared advisable the execution and delivery by the Company of the Merger Agreement, the performance by the Company of its covenants and agreements contained therein and the consummation of the Transactions contemplated by the Merger Agreement upon the terms and subject to the conditions contained therein, (iii) resolved that the Merger Agreement and the Merger be governed by Section 251(h) of the DGCL and that the Merger be effected as soon as practicable following the Acceptance Time without a vote of the Company stockholders, and (iv) resolved, subject to the terms and conditions set forth in the Merger Agreement, to recommend that the holders of the Shares accept the Offer and tender their Shares to Merger Sub pursuant to the Offer, which resolutions, except to the extent expressly permitted by the Merger Agreement, have not been rescinded, modified or withdrawn in any way.

If the Offer is consummated, we are not required to and will not seek the approval of the Company’s remaining stockholders before effecting the Merger. Section 251(h) of the DGCL provides that following the consummation of a successful tender offer for a public corporation, and subject to certain statutory provisions, if the acquirer holds at least the amount of shares of each class of stock of such corporation that would otherwise be required to approve a merger for such corporation, and the other stockholders receive the same consideration for their stock in the merger as was payable in the tender offer, the acquirer can effect a merger without a vote of the other stockholders of such corporation. Accordingly, if we consummate the Offer, we are required pursuant to the Merger Agreement to complete the Merger without a vote of the Company stockholders in accordance with Section 251(h) of the DGCL.

Plans for the Company

At the Effective Time, (a) by virtue of the Merger and without necessity of further action by the Company or any other person, the certificate of incorporation of the Company will be amended and restated in its entirety to read as set forth on Annex B to the Merger Agreement and (b) without necessity of further action by the Company or any other person, the bylaws of the Company will be amended and restated in their entirety as set forth on Annex C to the Merger Agreement.

At the Effective Time, the Company and the Surviving Corporation will take all necessary action such that (a) the directors of Merger Sub immediately prior to the Effective Time, or such other individuals designated by Parent as of the Effective Time, will become the directors of the Surviving Corporation and (b) the officers of the Company immediately prior to the Effective Time, or such other individuals designated by Parent as of the Effective Time, will become the officers of the Surviving Corporation. David Meek is expected to become the Chief Executive Officer of the Company upon the Closing.

75

From and for a period of six years following the Effective Time, the Surviving Corporation and its subsidiaries will honor and fulfill in all respects the obligations of the Company and its subsidiaries under (i) the indemnification agreements that have been made available to Parent prior to the date of the Merger Agreement between (A) the Company and its subsidiaries and any of their current or former directors and officers and any person who becomes a director or officer of the Company or any of its subsidiaries and (B) the Company or any corporation, partnership, joint venture, trust, pension or other employee benefit plan or enterprise and the Indemnified Persons, and (ii) indemnification, expense advancement and exculpation provisions in the certificate of incorporation or bylaws of the Company and in the certificate of incorporation or bylaws (or equivalent governing documents) of any subsidiary of the Company, in each case as in effect on the date of the Merger Agreement. In addition, during the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, the Surviving Corporation and its subsidiaries shall cause the certificates of incorporation and bylaws of the Surviving Corporation and its subsidiaries to contain provisions with respect to elimination of liability of directors, indemnification, exculpation and the advancement of expenses that are no less favorable to the Indemnified Persons than the indemnification, exculpation and advancement of expenses provisions contained in the certificates of incorporation and bylaws of the Company and its subsidiaries as of the date of the Merger Agreement, and during such six year period, such provisions shall not be repealed, amended or otherwise modified (whether by merger, consolidation, division, conversion, domestication, transfer, continuance, share exchange, operation of law or otherwise) in any manner that is material and adverse to the Indemnified Persons except as required by applicable law or as provided for in the Merger Agreement.

Following the Merger, we intend to cause the Shares to be delisted from Nasdaq and deregistered under the Exchange Act.

Parent and Merger Sub are conducting a detailed review of the Company and its assets, corporate structure, capitalization, indebtedness, operations, properties, policies, management and personnel, and will consider which changes would be desirable in light of the circumstances that exist upon completion of the Offer and the Merger. Parent and Merger Sub will continue to evaluate the business and operations of the Company during the pendency of the Offer and after the consummation of the Offer and the Merger and will take such actions as they deem appropriate under the circumstances then existing. Thereafter, Parent intends to review such information as part of a comprehensive review of the Company’s business, operations, capitalization, indebtedness and management. Possible changes could include changes in the Company’s business, corporate structure, certificate of incorporation, bylaws, capitalization and management and/or changes to the Company Board. Plans may change based on further analysis and Parent, Merger Sub and, after completion of the Offer and the Merger, the new Surviving Corporation board of directors, reserve the right to change their plans and intentions at any time, as deemed appropriate.

Except as disclosed in this Offer to Purchase, Parent and Merger Sub do not have any present plan or proposal that would result in the acquisition by any person of additional securities of the Company, the disposition of securities of the Company, an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Company or the purchase, sale or transfer of a material amount of assets of the Company.

To the best knowledge of Parent and Merger Sub, except for certain pre-existing agreements described in the Schedule 14D-9, no material employment, equity contribution, or other agreement, arrangement or understanding between any executive officer or director of the Company, on the one hand, and Parent, Merger Sub or the Company, on the other hand, existed as of the date of the Merger Agreement, and neither the Offer nor the Merger is conditioned upon any executive officer or director of the Company entering into any such agreement, arrangement or understanding.

76

13. Certain Effects of the Offer

Because the Merger will be governed by Section 251(h) of the DGCL, no stockholder vote will be required to consummate the Merger. Promptly after the consummation of the Offer, and subject to the satisfaction of the remaining conditions set forth in the Merger Agreement, we and the Company will consummate the Merger as soon as practicable following the Acceptance Time pursuant to Section 251(h) of the DGCL. Immediately following the Merger, all of the outstanding Shares of the Company’s common stock will be held by Beacon Midco, Inc., a wholly owned subsidiary of Parent.

Margin Regulations. The Shares are currently “margin securities” under the Regulations of the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”), which has the effect, among other things, of allowing brokers to extend credit based on the use of Shares as collateral. Depending upon factors similar to those described above regarding the market for the Shares and stock quotations, it is possible that, following the Offer, the Shares would no longer constitute “margin securities” for the purposes of the margin regulations of the Federal Reserve Board and, therefore, could no longer be used as collateral for loans made by brokers.

Market for the Shares. If the Offer is successful, there will be no market for the Shares because Merger Sub intends to consummate the Merger as soon as practicable and subject to the satisfaction or waiver of certain conditions set forth in the Merger Agreement.

Nasdaq Listing. If the Offer is consummated, Merger Sub will complete the Merger on the day following the Acceptance Time, subject to the satisfaction or waiver of certain conditions set forth in the Merger Agreement. As a result, the Shares will no longer meet the requirements for continued listing on Nasdaq because there will only be a single holder of the Shares, which will be Parent. We intend to cause the delisting of the Shares from Nasdaq as soon after completion of the Merger as the requirements for such delisting are satisfied.

Exchange Act Registration. The Shares are currently registered under the Exchange Act. Such registration may be terminated upon application of the Company to the SEC if the Shares are neither listed on a national securities exchange nor held by 300 or more holders of record. Termination of registration of the Shares under the Exchange Act would substantially reduce the information required to be furnished by the Company to its stockholders and to the SEC and would make certain provisions of the Exchange Act no longer applicable to the Company, such as the short-swing profit recovery provisions of Section 16(b) of the Exchange Act, the requirement of furnishing a proxy statement pursuant to Section 14(a) of the Exchange Act in connection with stockholders’ meetings and the related requirement of furnishing an annual report to stockholders and the requirements of Rule 13e-3 under the Exchange Act with respect to “going private” transactions. Furthermore, the ability of “affiliates” of the Company and persons holding “restricted securities” of the Company to dispose of such securities pursuant to Rule 144 under the Securities Act of 1933, as amended, may be impaired or eliminated. If registration of the Shares under the Exchange Act were terminated, the Shares would no longer be “margin securities” or be eligible for listing on Nasdaq. We intend to cause the delisting of the Shares from Nasdaq and the termination of the registration of the Shares under the Exchange Act as soon after completion of the Merger as the requirements for such delisting and termination of registration are satisfied.

14. Dividends and Distributions

The Merger Agreement provides that from the date of the Merger Agreement to the Effective Time, the Company will not, and will not permit any of its subsidiaries to, split, combine, subdivide or reclassify any Company securities or authorize, declare, set aside, establish a record date for, make or pay any dividend or distribution (whether in cash, stock or property) on any Company securities (other than dividends paid to the Company or one of its wholly owned subsidiaries by a wholly owned subsidiary of the Company with regards to its capital stock or other equity interests).

77

15. Conditions to the Offer

For purposes of this Section 15, capitalized terms used in this Section 15 and defined in the Merger Agreement have the meanings set forth in the Merger Agreement, a copy of which is filed as Exhibit (d)(1) of the Schedule TO and is incorporated herein by reference. The obligation of Merger Sub to accept for payment and pay for Shares validly tendered and not validly withdrawn pursuant to the Offer is subject to the satisfaction (or waiver by Parent or Merger Sub as described below) of the conditions below as of immediately prior to the Expiration Time.

Notwithstanding any other provision of the Offer, but subject to compliance with the terms and conditions of the Merger Agreement, and in addition to (and not in limitation of) the obligations of Merger Sub to extend the Offer pursuant to the terms and conditions of the Merger Agreement, Merger Sub shall not be required to accept for payment or, subject to any applicable rules and regulations of the SEC (including Rule 14e-1(c) promulgated under the Exchange Act (relating to the obligation of Merger Sub to pay for or return tendered Shares promptly after termination or withdrawal of the Offer)), pay for any Shares that are validly tendered pursuant to the Offer and not validly withdrawn prior to the Expiration Time, and may extend, terminate or amend the Offer, in each case, only to the extent provided by the Merger Agreement, in the event that, as of the Expiration Time: (A) the Minimum Condition shall not have been satisfied; (B) any of the required regulatory approvals applicable to the Transactions contemplated by the Merger Agreement under any foreign antitrust law of certain specified jurisdictions (the “Regulatory Approvals Condition”) shall not have been obtained; or (C) any of the following conditions to the Offer shall not have been satisfied or waived by Parent or Merger Sub (to the extent such waiver is permitted by applicable law):

1. no governmental authority of competent and applicable jurisdiction shall have (i) enacted, issued or promulgated any law that is in effect as of immediately prior to the Expiration Time and has the effect of making the Offer, the acquisition of Shares by Parent or Merger Sub, or the Merger illegal or which has the effect of prohibiting or otherwise preventing the consummation of the Offer, the acquisition of Shares by Parent or Merger Sub, or the Merger, or (ii) issued or granted any order that is in effect as of immediately prior to the Expiration Time and has the effect of making the Offer, the acquisition of Shares by Parent or Merger Sub, or the Merger illegal or which has the effect of prohibiting or otherwise preventing the consummation of the Offer, the acquisition of Shares by Parent or Merger Sub, or the Merger (the “No Injunction Condition”);

2. (i) the representations and warranties of the Company contained in Section 4.9(a), Section 4.28(c) and Section 4.28(d) of the Merger Agreement shall be true and correct in all respects both as of the date of the Merger Agreement and as of the Expiration Time as though made as of such time; (ii) the representations and warranties of the Company contained in the first three sentences of Section 4.2(a), the first sentence of Section 4.2(b), Section 4.2(c)(i) and Section 4.2(c)(ii) and Section 4.11 of the Merger Agreement (in each case, without giving effect to any qualification as to “materiality” or Company Material Adverse Effect qualifiers set forth therein), shall be true and correct in all respects (except for any inaccuracies that individually or in the aggregate are de minimis) both as of the date of the Merger Agreement and as of the Expiration Time as though made as of such time (except to the extent expressly made as of an earlier date, in which case, as of such earlier date); (iii) the representations and warranties of the Company contained in Section 4.1, Section 4.2 (other than the first three sentences of Section 4.2(a)), the first sentence of Section 4.2(b), Section 4.2(c)(i) and Section 4.2(c)(ii)), Section 4.3, Section 4.4, Section 4.5, Section 4.6(a) (solely as to the Company), Section 4.26 and Section 4.28 (other than Section 4.28(c) and Section 4.28(d)) of the Merger Agreement (in each case, without giving effect to any qualification as to “materiality” or Company Material Adverse Effect qualifiers set forth therein), shall be true and correct in all material respects both as of the date of the Merger Agreement and as of the Expiration Time as though made as of such time (except to the extent expressly made as of an earlier date, in which case as of such earlier date); and (iv) any other representation and warranty of the Company contained in Article IV of the Merger Agreement (in each case, without giving effect to any qualification as to “materiality” or Company Material Adverse Effect qualifiers set forth therein) shall be true and correct in all respects both as of the date of the Merger Agreement and as of the Expiration Time as though made as of such time (except to the extent expressly made as of an earlier date, in which case, as of such earlier date), except, solely in the case of this clause (iv), where the failure to be so true

78

and correct has not had and would not have, individually or in the aggregate, a Company Material Adverse Effect (the “Accuracy of Representations and Warranties Condition”);

3. the Company shall have complied with and performed in all material respects all agreements and covenants to be complied with, or performed, by the Company under the Merger Agreement at or prior to the Expiration Time (the “Compliance with Covenants Condition”);

4. since the date of the Merger Agreement, there shall not have occurred and be continuing any Company Material Adverse Effect;

5. the Company shall have delivered to Parent a certificate, signed on behalf of the Company by its chief executive officer or chief financial officer, certifying that the conditions set forth in clauses (C)(2), (C)(3) and (C)(4) have been satisfied as of the Expiration Time; and

6. the Merger Agreement shall have not been terminated in accordance with its terms (the “No Termination Condition”).

The foregoing conditions constitute all of the conditions which must have been satisfied or waived (to the extent such waiver is permitted by applicable law and the terms of the Merger Agreement) as of the Expiration Time in accordance with the Merger Agreement; provided that such conditions do not limit the rights and obligations of Parent or Merger Sub to extend, terminate, amend and/or modify the Offer in accordance with the terms and conditions of the Merger Agreement and the applicable rules and regulations of the SEC. The foregoing conditions are for the sole benefit of Parent and Merger Sub and (except for the conditions set forth in clauses (A) and (C)(6) above) may be asserted by Parent or Merger Sub and may be waived by Parent or Merger Sub in whole or in part at any time and from time to time prior to the Acceptance Time in the sole discretion of Parent or Merger Sub, subject in each case to the terms of the Merger Agreement and the applicable rules and regulations of the SEC. The failure by Parent, Merger Sub or any other affiliate of Parent at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right, the waiver of any such right with respect to particular facts and circumstances shall not be deemed a waiver with respect to any other facts and circumstances and each such right shall be deemed an ongoing right that may be asserted at any time and from time to time.

16. Certain Legal Matters; Regulatory Approvals

General. Except as described in this Section 16, based on our examination of publicly available information filed by the Company with the SEC, other publicly available information concerning the Company and certain confidential information provided to us by the Company in connection with the negotiations for the Transactions contemplated by the Merger Agreement, we are not aware of any governmental license or regulatory permit (except as may be required under any applicable foreign antitrust or competition laws prohibiting, restricting or regulating foreign investments or foreign subsidies) that appears to be material to the Company’s business that would be adversely affected by our acquisition of Shares pursuant to the Offer or, except as set forth below in this Section 16, of any approval or other action by any government or governmental administrative or regulatory authority or agency, domestic or foreign, that would be required for our purchase of Shares pursuant to the Offer. Should any such approval or other action be required or desirable, we currently contemplate that, except for takeover laws in jurisdictions other than Delaware as described below under “State Takeover Laws,” such approval or other action will be sought. However, we do not anticipate delaying the purchase of Shares tendered pursuant to the Offer pending the outcome of any such matter. There can be no assurance that any such approval or action, if needed, will be obtained or, if obtained, that it will be obtained without substantial conditions; and there can be no assurance that, in the event that such approvals were not obtained or such other actions were not taken, adverse consequences might not result to the Company’s business or that certain parts of the Company’s business might not have to be disposed of or held separate, any of which may give us the right to terminate the Offer at any Expiration Time without accepting for payment any Shares validly tendered (and not properly withdrawn) pursuant to the Offer. Our obligation under the Offer to accept for payment and pay for Shares is subject to the Offer Conditions. See Section 15 – “Conditions to the Offer.”

79

Antitrust Compliance

Under the laws of certain jurisdictions, certain transactions resulting in “joint control,” including Merger Sub’s purchase of Shares pursuant to the Offer, may not be consummated until certain information and documentary material has been furnished to the applicable antitrust enforcers in those jurisdictions and either the applicable waiting period has expired or the enforcers have approved the transaction. Parent and its corporate owners have submitted or will submit initial drafts of their “joint control” filings in these jurisdictions. Although Merger Sub’s purchase of the Shares pursuant to the Offer is not subject in the United States to the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the rules and regulations promulgated thereunder, or any successor statute, rules and regulations thereto (the “HSR Act”), or any prenotification filing requirement and initial waiting period, antitrust enforcers in the United States may use their investigative powers to request information about the transaction.

The FTC and the Antitrust Division at times scrutinize the legality under the U.S. antitrust laws of transactions not subject to the HSR Act, like the Offer and the Merger. At any time, the FTC or the Antitrust Division could take any action under the antitrust laws that it considers necessary or desirable in the public interest, including by going to court to seek an order (i) to enjoin the purchase of Shares pursuant to the Offer, (ii) to enjoin the Merger, (iii) to require Merger Sub (or, after completion of the Merger, Parent) to divest the Shares, or (iv) to require us or the Company to divest businesses or assets or seek other relief. Private parties, as well as state attorneys general, also may bring legal actions under the antitrust laws under certain circumstances. At any time before or after the consummation of the Merger, notwithstanding the lack of a required filing or waiting period under the HSR Act, any state or private party could seek to enjoin the consummation of the Merger or seek other structural or relief or damages.

Based upon an examination of publicly available information and other information relating to the businesses in which the Company is engaged, Parent does not believe that either the purchase of Shares by Merger Sub pursuant to the Offer or the consummation of the Merger should violate applicable antitrust laws. Nevertheless, Parent cannot be certain that a challenge to the Offer or the Merger on antitrust grounds will not be made, or, if such challenge is made, what the result will be. See Section 15 – “Conditions to the Offer.”

State Takeover Laws

The Company is incorporated under the laws of the State of Delaware. In general, Section 203 of the DGCL prevents a Delaware corporation from engaging in a “business combination” (defined to include mergers and certain other actions) with an “interested stockholder” (including a person who owns or has the right to acquire 15% or more of a corporation’s outstanding voting stock) for a period of three years following the date such person became an “interested stockholder” unless, among other things, the “business combination” is approved by the board of directors of such corporation before such person became an “interested stockholder.” The Company Board approved the Merger Agreement and the Transactions contemplated therein, and the restrictions on “business combinations” described in Section 203 of the DGCL are inapplicable to the Merger Agreement and the Transactions contemplated by the Merger Agreement.

The Company has represented to us in the Merger Agreement that, assuming that the representations of Parent and Merger Sub set forth in the Merger Agreement are true, accurate and complete, the Company Board (or a duly authorized committee thereof) has taken all necessary actions so that the restrictions on business combinations set forth in Section 203 of the DGCL are not applicable to the Merger Agreement, the CVR Agreement and the transactions contemplated thereby, and to the knowledge of the Company, no other state takeover statute or similar statute or regulation applies to or purports to apply to the Offer or the Merger or the other transactions contemplated by the Merger Agreement. Merger Sub reserves the right to challenge the validity or applicability of any state law allegedly applicable to the Offer, the Merger, the Merger Agreement or the Transactions contemplated thereby, and nothing in this Offer to Purchase or any action taken in connection herewith is intended as a waiver of that right.

The Company conducts business in a number of states throughout the United States, some of which have enacted takeover laws. Other than Section 203 of the DGCL (as to which, as described above, the Company has

80

taken necessary action to render the restrictions on business combinations contained therein inapplicable to the Offer and the Merger), we do not know whether any of these laws will, by their terms, apply to the Offer or the Merger and have not attempted to comply with any such laws. Should any person seek to apply any state takeover law, we will take such action as then appears desirable, which may include challenging the validity or applicability of any such statute in appropriate court proceedings. In the event that it is asserted that the takeover laws of any state are applicable to the Offer or the Merger, and an appropriate court does not determine that such laws are inapplicable or invalid as applied to the Offer or the Merger, we may be required to file certain documents or information with, or receive approvals from, the relevant state authorities. In addition, if enjoined, we may be unable to accept for payment any Shares tendered pursuant to the Offer, or be delayed in continuing or consummating the Offer and the Merger. In such case, we may not be obligated to accept for payment or pay for any Shares tendered in the Offer. See Section 15 – “Conditions to the Offer.”

Going Private Transactions

The SEC has adopted Rule 13e-3 under the Exchange Act, which is applicable to certain “going private” transactions and which may under certain circumstances be applicable to the Merger or another business combination following the purchase of Shares pursuant to the Offer in which we seek to acquire the remaining Shares not then held by us. We believe that Rule 13e-3 under the Exchange Act will not be applicable to the Merger because: (i) we were not, at the time the Merger Agreement was executed, and are not, an affiliate of the Company for purposes of the Exchange Act; (ii) we anticipate that the Merger will be effected as soon as practicable after the consummation of the Offer (and in any event within one year following the consummation of the Offer); and (iii) in the Merger, stockholders will receive the same price per Share as the Offer Price.

Stockholder Approval Not Required

Section 251(h) of the DGCL generally provides that stockholder approval of a merger is not required if certain requirements are met, including that (i) the acquiring company consummates a tender offer for any and all of the outstanding common stock of the company to be acquired that, absent Section 251(h) of the DGCL, would be entitled to vote on the adoption of the merger agreement and (ii) following the consummation of such tender offer, the acquiring company owns at least such percentage of the stock of the company to be acquired that, absent Section 251(h) of the DGCL, would be required to adopt the merger. If the Minimum Condition is satisfied and we accept Shares for payment pursuant to the Offer, we will hold a sufficient number of Shares to consummate the Merger under Section 251(h) of the DGCL without submitting the adoption of the Merger Agreement to a vote of the Company stockholders. Following the consummation of the Offer and subject to the satisfaction of the remaining conditions set forth in the Merger Agreement, Parent, Merger Sub and the Company will take all necessary action to cause the Merger to become effective as soon as practicable after the Acceptance Time without a vote of the Company stockholders, as provided in Section 251(h) of the DGCL.

17. Appraisal Rights

No appraisal rights are available to the holders of Shares who tender such Shares in connection with the Offer. If the Offer and the Merger are consummated pursuant to Section 251(h) of the DGCL as contemplated by the Merger Agreement, the holders of Shares who: (i) did not tender their Shares pursuant to the Offer, (ii) follow the procedures set forth in Section 262 of the DGCL and (iii) do not thereafter lose their appraisal rights (by withdrawal, failure to perfect or otherwise), in each case in accordance with the DGCL, will be entitled to have their Shares appraised by the Delaware Court of Chancery and receive payment of the “fair value” of such Shares in accordance with Section 262, together with interest thereon, if any, as determined by such court. Unless the Delaware Court of Chancery in its discretion determines otherwise for good cause shown, interest from the effective date of the Merger through the date of payment of the judgment will be compounded quarterly and will accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the Merger and the date of payment of the judgment.

81

In determining the “fair value” of any Shares, the Court of Chancery will take into account all relevant factors. Holders of Shares should recognize that “fair value” so determined could be higher or lower than, or the same as, the Offer Price or the consideration payable in the Merger (which is equivalent in amount to the Offer Price) and that an investment banking opinion as to the fairness, from a financial point of view, of the consideration payable in a sale transaction, such as the Offer and the Merger, is not an opinion as to, and does not otherwise address, “fair value” under Section 262. Moreover, we may argue in an appraisal proceeding that, for purposes of such proceeding, the fair value of such Shares is less than the Offer Price.

Section 262 of the DGCL provides that, if a merger was approved pursuant to Section 251(h) of the DGCL, either a constituent corporation before the effective date of the merger or the surviving corporation within ten days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of Section 262 of the DGCL or information directing the holders to a publicly available electronic resource at which Section 262 of the DGCL may be accessed without subscription or cost. The Schedule 14D-9 constitutes the formal notice by the Company to its stockholders of appraisal rights in connection with the Merger under Section 262 of the DGCL.

As described more fully in the Schedule 14D-9, if a stockholder wishes to elect to exercise appraisal rights under Section 262 of the DGCL in connection with the Merger, such stockholder must do all of the following: prior to the later of the consummation of the Offer (that is, the Acceptance Time) and 20 days after the date of mailing of the Schedule 14D-9, deliver to the Company a written demand for appraisal of Shares held, which demand must reasonably inform the Company of the identity of the stockholder and that the stockholder is demanding appraisal; not tender such stockholder’s Shares in the Offer; and continuously hold of record the Shares from the date on which the written demand for appraisal is made through the Effective Time.

The foregoing summary of the appraisal rights of stockholders under the DGCL does not purport to be a complete statement of the procedures to be followed by any stockholders desiring to exercise any appraisal rights available thereunder and is qualified in its entirety by reference to Section 262 of the DGCL. The proper exercise of appraisal rights requires strict and timely adherence to the applicable provisions of the DGCL. A copy of Section 262 of the DGCL will be included as Annex II to the Schedule 14D-9.

The information provided above is for informational purposes only with respect to your alternatives if the Merger is consummated. If you tender your Shares into the Offer, you will not be entitled to exercise appraisal rights with respect to your Shares, but, instead, on the terms and subject to the conditions to the Offer, you will receive the Offer Price for your Shares.

Ladies and Gentlemen:

The undersigned hereby tenders to Beacon Merger Sub, Inc.

The Offer expires at the Expiration Time. “Expiration Time” means one minute after 11:59 p.m., New York City time, on April 4, 2025, unless the Offer is extended pursuant to and in accordance with the Agreement and Plan of Merger, dated as of February 21, 2025, by and among Parent, Merger Sub and the Company (as it may be amended, supplemented or otherwise modified from time to time, the “Merger Agreement”). In the event that the Offer is extended pursuant to and in accordance with the Merger Agreement, then the term “Expiration Time” means such subsequent time.

The undersigned hereby acknowledges that Merger Sub reserves the right to assign, in its sole discretion, in whole or in part, to any affiliate of Parent, without the consent of the Company, the right to purchase the Shares tendered herewith.

On the terms and subject to the conditions of the Offer (including, if the Offer is extended or amended, the terms and conditions of such extension or amendment), subject to, and effective upon, acceptance for payment of the Shares validly tendered herewith and not validly withdrawn prior to the Expiration Time in accordance with the terms of the Offer, the undersigned hereby sells, assigns and transfers to, or upon the order of, Merger Sub, all right, title and interest in and to all of the Shares being tendered hereby and any and all dividends, distributions, rights, other Shares or other securities issued or issuable in respect of such Shares on or after the date hereof (collectively, “Distributions”). In addition, the undersigned hereby irrevocably appoints Merger Sub as the true and lawful agent and attorney-in-fact and proxy of the undersigned with respect to such Shares and any and all Distributions with full power of substitution (such proxies and power of attorney being deemed to be an irrevocable power coupled with an interest in the tendered Shares and any Distributions) to the full extent of such stockholder’s rights with respect to such Shares and any Distributions (a) to deliver certificates representing such Shares (the “Share Certificates”) and any and all Distributions, or transfer of ownership of such Shares and any and all Distributions on the account books maintained by The Depository Trust Company (“DTC”), together, in either such case, with all accompanying evidence of transfer and authenticity, to or upon the order of Merger Sub, (b) to present such Shares and any and all Distributions for transfer on the books of the Company and (c) to receive all benefits and otherwise exercise all rights of beneficial ownership of such Shares and any and all Distributions, all upon the terms and subject to the conditions of the Offer.

By executing this Letter of Transmittal (or taking action resulting in the delivery of an Agent’s Message (as defined in Instruction 2 below)), the undersigned hereby irrevocably appoints each of the designees of Merger

Sub the attorneys-in-fact and proxies of the undersigned, each with full power of substitution, to the full extent of such stockholder’s rights with respect to the Shares tendered hereby and not properly withdrawn which have been accepted for payment and with respect to any and all Distributions. The designees of Merger Sub will, with respect to such Shares and Distributions, be empowered to exercise all voting and any other rights of such stockholder, as they, in their sole discretion, may deem proper at any annual, special, adjourned or postponed meeting of the Company stockholders, by written consent in lieu of any such meeting or otherwise as such designee, in its, his or her sole discretion, deems proper with respect to all Shares and any and all Distributions. This proxy and power of attorney will be irrevocable and coupled with an interest in the tendered Shares and any and all Distributions. Such appointment is effective when, and only to the extent that, Merger Sub accepts the Shares tendered with this Letter of Transmittal for payment pursuant to the Offer. Upon the effectiveness of such appointment, without further action, all prior powers of attorney, proxies and consents given by the undersigned with respect to such Shares and any and all associated Distributions (other than prior powers of attorney, proxies or consent given by the undersigned to Merger Sub or the Company) will be revoked, and no subsequent powers of attorney, proxies, consents or revocations (other than powers of attorney, proxies, consents or revocations given to Merger Sub or the Company) may be given (and, if given, will not be deemed effective).

Merger Sub reserves the right to require that, in order for Shares to be deemed validly tendered, immediately upon Merger Sub’s acceptance for payment of such Shares, Merger Sub must be able to exercise full voting, consent and other rights, to the extent permitted under applicable law, with respect to such Shares and any and all Distributions, including voting at any meeting of stockholders or executing a written consent concerning any matter.

The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, sell, assign and transfer any and all of the Shares tendered hereby and any and all Distributions and, when the same are accepted for payment by Merger Sub, Merger Sub will acquire good, marketable and unencumbered title thereto, free and clear of all liens, restrictions, charges and encumbrances, and that the same will not be subject to any adverse claim. The undersigned hereby represents and warrants that the undersigned is the registered owner of the Shares, or the Share Certificate(s) have been endorsed to the undersigned in blank, or the undersigned is a participant in DTC whose name appears on a security position listing as the owner of the Shares. The undersigned will, upon request, execute and deliver any additional documents deemed by the Depositary or Merger Sub to be necessary or desirable to complete the sale, assignment and transfer of any and all of the Shares tendered hereby and any and all Distributions. In addition, the undersigned will promptly remit and transfer to the Depositary for the account of Merger Sub any and all Distributions in respect of any and all of the Shares tendered hereby, accompanied by appropriate documentation of transfer and, pending such remittance and transfer or appropriate assurance thereof, Merger Sub will be entitled to all rights and privileges as owner of any such Distributions and may withhold the entire Offer Price or deduct from such Offer Price the amount or value thereof, as determined by Merger Sub in its sole discretion.

It is understood that the undersigned will not receive payment for the Shares unless and until the Shares are accepted for payment and until the Share Certificate(s) owned by the undersigned are received by the Depositary at the address set forth above, together with such additional documents as the Depositary may require, or, in the case of Shares held in book-entry form, ownership of Shares is validly transferred on the account books maintained by DTC, and until the same are processed for payment by the Depositary.

It is understood that the method of delivery of the Shares, the Share Certificate(s) and all other required documents (including delivery through DTC) is at the election and risk of the undersigned and that the risk of loss of such Shares, Share Certificate(s) and other documents will pass only when they are actually received by the Depositary (including, in the case of a book-entry transfer of Shares, by Book-Entry Confirmation with respect to such Shares). If such delivery is by mail, it is recommended that the Shares (or Share Certificates), the Letter of Transmittal and all other required documents be sent by properly insured registered mail with return receipt requested. In all cases, sufficient time should be allowed to ensure timely delivery.

All authority conferred or agreed to be conferred pursuant to this Letter of Transmittal will not be affected by, and will survive, the death or incapacity of the undersigned and any obligation of the undersigned hereunder will be binding upon the heirs, executors, administrators, trustees in bankruptcy, personal representatives, successors and assigns of the undersigned. Except upon the terms and subject to the conditions of the Offer, this tender is irrevocable.

The undersigned understands that the acceptance for payment by Merger Sub of Shares tendered pursuant to one of the procedures described in Section 3 of the Offer to Purchase and in the instructions hereto will constitute a binding agreement between the undersigned and Merger Sub upon the terms and subject to the conditions of the Offer. The undersigned recognizes that under certain circumstances, upon the terms and subject to the conditions of the Offer, Merger Sub may not be required to accept for payment any of the Shares tendered hereby.

Unless otherwise indicated herein under “Special Payment Instructions,” please issue the check for the Offer Price in the name(s) of, and/or return any Share Certificates representing Shares not validly tendered or accepted for payment to, the registered owner(s) appearing under “Description of Shares Tendered.” Similarly, unless otherwise indicated under “Special Delivery Instructions,” please mail the check for the Offer Price and/or return any Share Certificates representing Shares not validly tendered or accepted for payment (and accompanying documents, as appropriate) to the address(es) of the registered owner(s) appearing under “Description of Shares Tendered.”

In the event that both the Special Delivery Instructions and the Special Payment Instructions are completed, please issue the check for the Offer Price and/or issue any Share Certificates representing Shares not validly tendered or accepted for payment (and any accompanying documents, as appropriate) in the name of, and deliver such check and/or return such Share Certificates (and any accompanying documents, as appropriate) to, the person or persons so indicated. Unless otherwise indicated herein in the box titled “Special Payment Instructions,” please credit any Shares validly tendered hereby or by an Agent’s Message and delivered by book-entry transfer, but which are not purchased, by crediting the account at DTC designated above. The undersigned recognizes that Merger Sub has no obligation pursuant to the Special Payment Instructions to transfer any Shares from the name of the registered owner thereof if Merger Sub does not accept for payment any of the Shares so validly tendered.

INSTRUCTIONS

Forming Part of the Terms and Conditions of the Offer

1. Guarantee of Signatures for Shares. No signature guarantee is required on this Letter of Transmittal (a) if this Letter of Transmittal is signed by the registered holder(s) (which term, for purposes of this Section 1, includes any participant in DTC’s systems whose name appears on a security position listing as the owner of the Shares) of the Shares tendered therewith, unless such holder or holders have completed either the box entitled “Special Delivery Instructions” or the box entitled “Special Payment Instructions” within this Letter of Transmittal or (b) if the Shares are tendered for the account of a financial institution (including most commercial banks, savings and loan associations and brokerage houses) that is a member in good standing of the Security Transfer Agents Medallion Program or any other “eligible guarantor institution,” as such term is defined in Rule 17Ad-15 of the Exchange Act (each an “Eligible Institution” and collectively “Eligible Institutions”) (for example, the Security Transfer Agents Medallion Program, the New York Stock Exchange Medallion Signature Program and the Stock Exchanges Medallion Program). In all other cases, all signatures on this Letter of Transmittal must be guaranteed by an Eligible Institution. See Instruction 5.

2. Requirements of Tender. In order for Shares to be validly tendered pursuant to the Offer, one of the following procedures must be followed:

For Shares held as physical certificates, the Share Certificates representing tendered Shares, a properly completed and duly executed Letter of Transmittal together with any required signature guarantees and any other documents required by this Letter of Transmittal, must be received by the Depositary at one of its addresses set forth on the front page of this Letter of Transmittal before the Offer expires.

For Shares held in book-entry form on the books of the Company, a properly completed and duly executed Letter of Transmittal, together with any required signature guarantees, and any other required documents, must be received by the Depositary at the appropriate address set forth on the front page of this Letter of Transmittal, and such Shares must be delivered according to the book-entry transfer procedure (as set forth in Section 3 of the Offer to Purchase), before the Offer expires.

For Shares held in “street” name in book-entry form, an Agent’s Message in lieu of this Letter of Transmittal and a timely confirmation of a book-entry transfer of Shares into the Depositary’s account at DTC (a “Book-Entry Confirmation”) must be received by the Depositary before the Offer expires. Stockholders holding Shares in “street” name in book-entry form need not complete a Letter of Transmittal.

The term “Agent’s Message” means a message transmitted through electronic means by DTC in accordance with the normal procedures of DTC to, and received by, the Depositary and forming part of a Book-Entry Confirmation, that states that DTC has received an express acknowledgment from the participant in DTC tendering the Shares that are the subject of such Book-Entry Confirmation that such participant has received and agrees to be bound by the terms of, this Letter of Transmittal, and that Merger Sub may enforce such agreement against such participant. The term “Agent’s Message” also includes any hard copy printout evidencing such message generated by a computer terminal maintained at the Depositary’s office.

The method of delivery of the Shares (or Share Certificates), this Letter of Transmittal and all other required documents, including delivery through DTC, is at the election and risk of the tendering stockholder. Delivery of the Shares (or Share Certificates), this Letter of Transmittal and all other required documents will be deemed made, and risk of loss thereof will pass, only when they are actually received by the Depositary (including, in the case of a book-entry transfer of Shares, by Book-Entry Confirmation with respect to such Shares). If such delivery is by mail, it is recommended that the Shares (or Share Certificates), this Letter of Transmittal and all other required documents be sent by properly insured registered mail with return receipt requested. In all cases, sufficient time should be allowed to ensure timely delivery.

No Guaranteed Delivery. We are not providing for guaranteed delivery procedures. Therefore, Company stockholders must allow sufficient time for the necessary tender procedures to be completed prior to the Expiration Time. In addition, for Company stockholders who are registered holders, the Letter of Transmittal, properly completed and duly executed, together with any required signature guarantees and any other documents required by the Letter of Transmittal (or, in the case of a book-entry transfer, an Agent’s Message in lieu of the Letter of Transmittal and such other documents) must be received by the Depositary prior to the Expiration Time.

No alternative, conditional or contingent tenders will be accepted and no fractional Shares will be purchased. All tendering stockholders, by execution of this Letter of Transmittal, waive any right to receive any notice of the acceptance of their Shares for payment.

All questions as to validity, form and eligibility (including time of receipt) of the surrender of any Share Certificate hereunder, including questions as to the proper completion or execution of any Letter of Transmittal or other required documents and as to the proper form for transfer of any certificate of Shares, will be determined by Merger Sub in its sole and absolute discretion (which may be delegated in whole or in part to the Depositary), which determination will be final and binding, subject to any judgment of any court of competent jurisdiction. Merger Sub reserves the absolute right to reject any and all tenders determined by it not to be in proper form or the acceptance for payment of or payment for which may be unlawful. Merger Sub also reserves the absolute right to waive any defect or irregularity in the surrender of any Shares or Share Certificate(s) whether or not similar defects or irregularities are waived in the case of any other stockholder. A surrender will not be deemed to have been validly made until all defects and irregularities have been cured or waived.

3. Inadequate Space. If the space provided on the cover page to this Letter of Transmittal is inadequate, the certificate numbers and/or the number of Shares should be listed on a separate schedule attached hereto and separately signed on each page thereof in the same manner as this Letter of Transmittal is signed.

4. Partial Tenders. Unless otherwise indicated, it will be considered that all Shares represented by a certificate(s) delivered with the Letter of Transmittal or held in the account in book-entry form are to be tendered.

5. Signatures on Letter of Transmittal; Stock Powers and Endorsements. If this Letter of Transmittal is signed by the registered owner(s) of the Shares tendered hereby, the signature(s) must correspond with the name(s) as written on the face of the Share Certificate(s) without alteration or any other change whatsoever.

If any Shares tendered hereby are owned of record by two or more joint owners, all such owners must sign this Letter of Transmittal.

If any tendered Shares are registered in the names of different holder(s), it will be necessary to complete, sign and submit as many separate Letters of Transmittal as there are different registrations of such Shares.

If this Letter of Transmittal or any certificates or stock powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, and proper evidence satisfactory to Merger Sub of their authority so to act must be submitted.

If this Letter of Transmittal is signed by the registered owner(s) of the Shares listed and transmitted hereby, no endorsements of Share Certificates or separate stock powers are required unless payment is to be made to, or Share Certificates representing Shares not tendered or accepted for payment are to be issued in the name of, a person other than the registered owner(s), in which case the Share Certificates representing the Shares tendered by this Letter of Transmittal must be endorsed or accompanied by appropriate stock powers, in either case, signed exactly as the name(s) of the registered owner(s) or holder(s) appear(s) on the Share Certificates. Signatures on such Share Certificates or stock powers must be guaranteed by an Eligible Institution.

If this Letter of Transmittal is signed by a person other than the registered owner(s) of the Share(s) listed, the Share Certificate(s) must be endorsed or accompanied by the appropriate stock powers, in either case, signed exactly as the name or names of the registered owner(s) or holder(s) appear(s) on the Share Certificate(s). Signatures on such Share Certificates or stock powers must be guaranteed by an Eligible Institution.

6. Transfer Taxes. Except as otherwise provided in this Instruction 6, all transfer taxes with respect to the transfer and sale of Shares contemplated hereby will be paid or caused to be paid by Merger Sub. If payment of the Offer Price is to be made to, or (in the circumstances permitted hereby) if Share Certificates not validly tendered or accepted for payment are to be registered in the name of, any person other than the registered owner(s), or if tendered Share Certificates are registered in the name of any person other than the person signing this Letter of Transmittal, the amount of any transfer taxes whether imposed on the registered owner(s) or such person payable on account of the transfer to such person will be deducted from the Offer Price unless satisfactory evidence of the payment of such taxes, or exemption therefrom, is submitted.

7. Special Payment and Delivery Instructions. If a check for the Offer Price is to be issued, and/or Share Certificates representing Shares not validly tendered or accepted for payment are to be issued or returned to, a person other than the signer(s) of this Letter of Transmittal or to an address other than that shown in the box titled “Description of Shares Tendered” above, the appropriate boxes on this Letter of Transmittal should be completed. Stockholders delivering Shares tendered hereby or by Agent’s Message by book-entry transfer may request that Shares not purchased be credited to an account maintained at DTC as such stockholder may designate in the box titled “Special Payment Instructions” herein. If no such instructions are given, all such Shares not purchased will be returned by crediting the same account at DTC as the account from which such Shares were delivered.

8. Requests for Assistance or Additional Copies. Questions or requests for assistance may be directed to Innisfree M&A Incorporated (the “Information Agent”) at its address and telephone number set forth below or to your broker, dealer, commercial bank or trust company. Additional copies of the Offer to Purchase, this Letter of Transmittal and other tender offer materials may be obtained from the Information Agent as set forth below, and will be furnished at Merger Sub’s expense.

9. U.S. Federal Backup Withholding. Under U.S. federal income tax laws, the Depositary will be required to withhold a portion of the amount of any payments made to certain stockholders (or other payees) pursuant to the Offer (including the value of the CVR as determined for U.S. federal income tax purposes). To avoid backup withholding, each tendering stockholder (or other payee) that is or is treated as a United States person (for U.S. federal income tax purposes) and that does not otherwise establish an exemption from U.S. federal backup withholding must complete and return the attached Internal Revenue Service (“IRS”) Form W-9, certifying that such stockholder (or other payee) is a United States person, that the taxpayer identification number (“TIN”) provided is correct, and that such stockholder (or other payee) is not subject to backup withholding. If such stockholder (or other payee) is a U.S. individual, the TIN is such stockholder’s (or other payee’s) social security number.

Certain stockholders and other payees (including, among others, corporations, non-resident foreign individuals and certain foreign entities) are not subject to these backup withholding and reporting requirements. To avoid backup withholding, exempt U.S. persons should furnish their TIN and indicate their exempt status on IRS Form W-9 and sign, date and return the IRS Form W-9 to the Depositary. A tendering stockholder (or other payee) that is a foreign individual or a foreign entity should complete, sign, and submit to the Depositary IRS Form W-8BEN or IRS Form W-8BEN-E (or other applicable IRS Form W-8) attesting to such stockholder’s (or payee’s) foreign status or should otherwise establish an exemption. Special rules apply for foreign entities or arrangements treated as partnerships for U.S. federal income tax purposes. The appropriate IRS Form W-8 may be downloaded from the Internal Revenue Service’s website at the following address: http://www.irs.gov. Failure to complete the IRS Form W-9 or the appropriate IRS Form W-8 will not, by itself, cause Shares to be deemed invalidly tendered, but may require the Depositary to withhold a portion of the amount of any payments made of the Offer Price pursuant to the Offer. Tendering stockholders (or other payees) should consult their own tax advisors as to any qualification for exemption from backup withholding, and the procedure for obtaining the exemption.

If backup withholding of U.S. federal income tax on payments for Shares made in the Offer or under the Merger Agreement applies, the Depositary is required to withhold (currently at a rate of 24%) form any payments of the Offer Price made to the stockholder (or other payee). Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be refunded or credited against a stockholder’s U.S. federal income tax liability, if any, if the stockholder timely furnishes the required information to the IRS.

Note: Failure to complete and return the IRS Form W-9 (or appropriate IRS Form W-8, as applicable) may result in backup withholding of a portion of any payments made to you pursuant to the Offer.

10. Lost, Destroyed, Mutilated or Stolen Share Certificates. If any Share Certificate has been lost, destroyed, mutilated or stolen, the stockholder should promptly notify the Transfer Agent, at (877) 248-6417 (toll free in the United States). The stockholder will then be instructed as to the steps that must be taken in order to replace the Share Certificate. This Letter of Transmittal and related documents cannot be processed until the procedures for replacing lost, mutilated, destroyed or stolen Share Certificates have been followed.

11. Waiver of Conditions. Parent and Merger Sub expressly reserve the right, at any time and from time to time, to waive, in whole or in part, any of the Offer Conditions (as defined in the Offer to Purchase) and to make any change in the terms of or conditions to the Offer in a manner consistent with the terms of the Merger Agreement or to increase the Offer Price. However, without the prior written consent of the Company, Parent and Merger Sub may not (and Parent may not permit Merger Sub to): (i) waive or modify the Minimum Condition (as defined in the Offer to Purchase), the No Injunction Condition (as defined in the Offer to Purchase) or the No Termination Condition (as defined in the Offer to Purchase); or (ii) make any change in the terms of or conditions to the Offer that: (A) changes the form of consideration to be paid in the Offer; (B) decreases the Offer Price or the number of Shares sought in the Offer; (C) extends the Offer or the Expiration Time, except as permitted or required by the Merger Agreement; (D) imposes conditions or requirements on the Offer other than the Offer Conditions, as described in Section 15 of the Offer to Purchase; (E) amends or modifies any term or condition of the Offer in any manner that is (or would reasonably be expected to be) material and adverse to the Company stockholders; or (F) would, individually or in the aggregate, reasonably be expected to prevent or materially delay the consummation of the Offer or prevent, materially delay or materially impair the ability of Parent or Merger Sub to consummate the Offer, the Merger or the other transactions contemplated by the Merger Agreement.

Important: This Letter of Transmittal or an Agent’s Message, together with Share Certificate(s) or Book-Entry Confirmation and all other required documents, must be received by the Depositary prior to the Expiration Time.

To Brokers, Dealers, Commercial Banks, Trust Companies and Other Nominees:

We have been engaged by Beacon Merger Sub, Inc. (“Merger Sub”), a Delaware corporation and an indirect wholly owned subsidiary of Beacon Parent Holdings, L.P. (“Parent”), a Delaware limited partnership, to act as information agent (the “Information Agent”) in connection with Merger Sub’s offer to purchase all of the outstanding shares of common stock, par value $0.01 per share (the “Shares”), of bluebird bio, Inc., a Delaware corporation (the “Company”), in exchange for (i) $3.00 in cash per Share on the terms and subject to the conditions set forth in the Offer to Purchase (as it may be amended, supplemented or otherwise modified from time to time, the “Offer to Purchase”) and in the related Letter of Transmittal (as it may be amended, supplemented or otherwise modified from time to time, the “Letter of Transmittal,” which, together with the Offer to Purchase, as they may be amended, supplemented or otherwise modified from time to time, collectively constitute the “Offer”), subject to any applicable withholding taxes and without interest thereon (the “Closing Amount”), plus (ii) one contingent value right (each, a “CVR”) per Share, subject to and in accordance with the terms and conditions set forth in the Contingent Value Rights Agreement that will be entered into by and among Parent, a rights agent mutually agreeable to Parent and the Company, and, solely for certain purposes, the Surviving Corporation (as defined herein) (the “CVR Agreement”), representing the right to receive one contingent payment of $6.84 in cash, subject to any applicable withholding taxes and without interest thereon, payable upon the achievement of the milestone set forth in, and subject to the terms and conditions of the CVR Agreement, the Offer to Purchase and the related Letter of Transmittal (the Closing Amount plus one CVR, collectively, or any greater amount per Share that may be paid pursuant to the Offer, the “Offer Price”).

The conditions to the Offer are described in Section 15 of the Offer to Purchase.

For your information and for forwarding to your clients for whom you hold Shares registered in your name or in the name of your nominee, we are enclosing the following documents:

We urge you to contact your clients as promptly as possible. Please note that the Offer and withdrawal rights will expire one minute after 11:59 p.m., New York City time, on April 4, 2025, unless the Offer is extended or earlier terminated. We are not providing for guaranteed delivery procedures.

The Offer is being made pursuant to an Agreement and Plan of Merger, dated as of February 21, 2025 (as it may be amended, supplemented or otherwise modified from time to time, the “Merger Agreement”), by and among the Company, Parent and Merger Sub, pursuant to which, as soon as practicable following the date and time of the irrevocable acceptance for payment (the “Acceptance Time”) by Merger Sub of Shares validly tendered and not validly withdrawn pursuant to and subject to the conditions set forth in Section 15 of the Offer to Purchase, subject to the satisfaction of or, if permitted by applicable law, waiver of certain conditions, and in any event no later than one business day thereafter, Merger Sub will merge with and into the Company (such merger, the “Merger”), and the Company will survive the Merger as an indirect wholly owned subsidiary of Parent (the “Surviving Corporation”), on the terms and subject to the conditions set forth in the Merger Agreement. The Merger will be governed by Section 251(h) of the Delaware General Corporation Law (the “DGCL”) and will be effected by Merger Sub and the Company without a stockholder vote pursuant to the DGCL as soon as practicable following the Acceptance Time, subject to the satisfaction or, if permitted by applicable law, waiver of certain conditions, and in any event no later than one business day thereafter.

At the effective time of the Merger (being the time and day of the filing of the certificate of merger in accordance with the DGCL (the “Certificate of Merger”) with the Secretary of State of the State of Delaware or at such later time and day as may be agreed in writing by Parent and the Company and specified in the Certificate of Merger in accordance with the DGCL, the “Effective Time”), each Share issued and outstanding at the commencement of the Offer and immediately prior to the Effective Time (excluding Shares owned by Parent, Merger Sub or the Company, or by any direct or indirect wholly owned subsidiary of Parent or Merger Sub, in each case, at the commencement of the Offer and immediately prior to the Effective Time, any Shares irrevocably accepted for purchase pursuant to the Offer (“Accepted Shares”), and any Shares held by stockholders who are entitled to demand, and who shall have properly and validly demanded their statutory rights of appraisal in respect of such Shares in compliance with Section 262 of the DGCL), shall be canceled and extinguished and automatically converted into the right to receive the Offer Price upon compliance with the procedures set forth in the Merger Agreement, without interest thereon and subject to any applicable withholding tax pursuant to the Merger Agreement and the CVR Agreement; provided that, at the election of Parent, any Shares owned by any direct or indirect subsidiary of the Company that are not Accepted Shares will instead receive shares of the Surviving Corporation of equivalent value. As a result of the Merger, the Company will cease to be a publicly traded company and will become an indirect wholly owned subsidiary of Parent.

The board of directors of the Company has unanimously (i) determined that the Merger Agreement and the transactions contemplated thereby, including the Offer and the Merger (the “Transactions”), are advisable, fair to and in the best interests of the Company and its stockholders, and declared it advisable for

the Company to enter into the Merger Agreement and consummate the Transactions contemplated therein, (ii) approved and declared advisable the execution and delivery by the Company of the Merger Agreement, the performance by the Company of its covenants and agreements contained therein and the consummation of the Transactions contemplated by the Merger Agreement upon the terms and subject to the conditions contained therein, (iii) resolved that the Merger Agreement and the Merger be governed by Section 251(h) of the DGCL and that the Merger be effected as soon as practicable following the Acceptance Time without a vote of the Company stockholders, and (iv) resolved, subject to the terms and conditions set forth in the Merger Agreement, to recommend that the holders of the Shares accept the Offer and tender their Shares to Merger Sub pursuant to the Offer, which resolutions, except to the extent expressly permitted by the Merger Agreement, have not been rescinded, modified or withdrawn in any way.

For Shares to be validly tendered to Merger Sub and accepted for payment pursuant to the Offer, (i) the certificates evidencing such Shares (the “Share Certificates”), (ii) confirmation of a book-entry transfer of such Shares into the Depositary’s account at The Depository Trust Company pursuant to the procedures set forth in Section 3 of the Offer to Purchase, with respect to Shares held in “street” name, (iii) in the case of Share Certificates, the Letter of Transmittal, properly completed and duly executed, with any required signature guarantees and (iv) any other documents required by the Letter of Transmittal or, in the case of a book-entry transfer of Shares held in “street” name, an “agent’s message” in lieu of the Letter of Transmittal and such other documents, must be timely received by the Depositary.

Neither Parent nor Merger Sub will pay any fees or commissions to any broker or dealer or to any other person (other than to the Depositary and the Information Agent as described in Section 18 of the Offer to Purchase) in connection with the solicitation of tenders of Shares pursuant to the Offer. Brokers, dealers, commercial banks and trust companies will, upon request, be reimbursed by Merger Sub for customary mailing and handling expenses incurred by them in forwarding offering materials to their customers. Merger Sub will pay all stock transfer taxes applicable to its purchase of Shares pursuant to the Offer, subject to Instruction 6 of the Letter of Transmittal.
