of the proposed transaction, and the financial condition, results of operations, earnings outlook and prospects of the Company and/or

“could,” “may,” “might,” “possible,” “potential,” “predict,” “seem,”

The forward-looking statements are based on the
current expectations of the management of the Company and HUB, as applicable, and are inherently subject to uncertainties and changes
in circumstances and their potential effects and speak only as of the date of such statement. There can be no assurance that future developments
will be those that have been anticipated. These forward-looking statements involve a number of risks, uncertainties or other assumptions
that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements.
These risks and uncertainties include, but are not limited to, those discussed and identified in public filings made with the SEC by the
Company and HUB and the following:
| · | expectations regarding HUB’s strategies and future financial performance, including its future business
plans or objectives, prospective performance and opportunities and competitors, revenues, products and services, pricing, operating expenses,
market trends, liquidity, cash flows and uses of cash, capital expenditures, and HUB’s ability to invest in growth initiatives and
pursue acquisition opportunities; |
| · | the occurrence of any event, change or other circumstances that could give rise to the termination of
the Business Combination Agreement and any subsequent definitive agreements with respect to the transaction contemplated therein; |
| · | the outcome of any legal proceedings that may be instituted against the Company, HUB, the Surviving Company
or others following announcement of the Business Combination Agreement and the transaction contemplated therein; |

or complete regulatory reviews required to complete the proposed transaction; |
| · | the inability to obtain the financing necessary to consummate the proposed transaction; |
| · | changes to the proposed structure of the proposed transactions that may be required or appropriate as
a result of applicable laws or regulations or as a condition to obtaining regulatory approval of the proposed transaction; |
| · | the ability to meet stock exchange listing standards following the consummation of the proposed transaction; |
| · | the risk that the announcement and consummation of the proposed transaction disrupts HUB’s current
operations and future plans; |
| · | the lack of a third party valuation in determining whether or not to pursue the proposed transaction; |
| · | the ability to recognize the anticipated benefits of the proposed transaction, which may be affected by,
among other things, competition, the ability of HUB to grow and manage growth profitably, maintain relationships with customers and suppliers
and retain its management and key employees; |
| · | costs related to the proposed transaction; |
| · | the amount of any redemptions by existing holders of the Company’s common stock being greater than
expected; |
| · | limited liquidity and trading of the Company’s and HUB’s securities; |
| · | geopolitical risk, including military action and related sanctions, and changes in applicable laws or
regulations; |
| · | the possibility that the Company or HUB may be adversely affected by other economic, business, and/or
competitive factors; |
| · | inaccuracies for any reason in the estimates of expenses and profitability and projected financial information
for HUB; and |

material respects from those expressed or implied in these forward-looking statements.
