(e) If the Stockholders Representative does not properly deliver a Dispute Notice to the Surviving Company prior to the expiration of the Review Period, Parent's calculation of Closing Liabilities and Debt, Closing Net Working Capital Amount and Unpaid Company Transaction Expenses set forth in the Closing Date Schedule shall be deemed final and binding on Parent, the Surviving Company, the Stockholders Representative and the stockholders of the Company immediately prior to the Effective Time for all purposes of this Agreement.

(f) If the Stockholders Representative delivers a Dispute Notice to Parent prior to the expiration of the Review Period, then the Stockholders Representative and Parent shall negotiate in good faith to reach agreement on Closing Liabilities and Debt, Closing Net Working Capital Amount and Unpaid Company Transaction Expenses.

The fees and expenses of the Accounting Firm shall be borne by Parent and the Stockholders Representative (on behalf of the stockholders of the Company immediately prior to the Effective Time) in proportion to how close each party's position was to the Determination of the Accounting Firm.

In addition, Parent shall deposit, or cause to be deposited, with the Exchange Agent, as necessary from time to time after the Effective Time cash in lieu of any fractional shares payable pursuant to Section 2.6(k). All shares of Parent Common Stock and cash deposited with the Exchange Agent pursuant to this Section 2.6(a) shall hereinafter be referred to as the "Exchange Fund." The Exchange Fund shall not be used for any purpose other than to fund the aggregate Merger Consideration payable pursuant to Section 2.1(a). Parent or the Surviving Company shall pay all charges and expenses, including those of the Exchange Agent, incurred by it in connection with the exchange of Shares for the Merger Consideration.

8

(b) Promptly after the Effective Time and in any event not later than the fifth (5th) Business Day following the Effective Time, the Surviving Company shall cause the Exchange Agent (i) in the case of each holder of record as of the Effective Time of a certificate ("Certificates") that immediately prior to the Effective Time represented outstanding Shares that were converted into the right to receive the Merger Consideration, to mail (A) a form of letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates held by such Person shall pass, only upon proper delivery of the Certificates to the Exchange Agent) in customary form and (B) instructions for use in effecting the surrender of such Certificates in exchange for the Merger Consideration and (ii) in the case of each holder of uncertificated Shares represented by book entry ("Book-Entry Shares"), to mail customary provisions regarding delivery of an "agent's message" with respect to such Book-Entry Shares. Upon surrender of a Certificate or Book-Entry Shares to the Exchange Agent, together with, in the case of certificated Shares, such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as the Exchange Agent may reasonably require, the holder of such Certificate or Book-Entry Shares shall be entitled to receive in exchange for the Shares formerly represented by such Certificate or Book-Entry Shares (other than Excluded Shares and Dissenting Shares) the Merger Consideration for each such Share and any cash in lieu of fractional shares pursuant to Section 2.6(k), and the Certificate and Book-Entry Shares so surrendered shall forthwith be cancelled. No interest will be paid or accrued for the benefit of holders of Certificates or Book-Entry Shares on the Merger Consideration.

(c) If payment of the Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate is registered, it shall be a condition of payment that such Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and shall be properly transferred, and that the Person requesting such payment shall have paid any transfer and other Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of such Certificate or shall have established to the satisfaction of Parent that such Tax either has been paid or is not applicable.

(d) Until surrendered as contemplated by this Section 2.6, each Certificate or Book-Entry Share shall be deemed after the Effective Time to represent only the right to receive the Merger Consideration payable in respect thereof, pursuant to this Article II, without any interest thereon.

(e) All Merger Consideration paid upon the surrender for exchange of Certificates or Book-Entry Shares in accordance with the terms of this Article II shall be deemed to have been paid in full satisfaction of all rights pertaining to the Shares formerly represented by such Certificates or Book-Entry Shares. At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers of the Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Company or the Exchange Agent for transfer or transfer is sought for Book-Entry Shares, such Certificates or Book-Entry Shares shall be cancelled and exchanged as provided in this Article II, subject to applicable Law in the case of Dissenting Shares.

9

(f) The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Parent, on a daily basis. If for any reason (including investment losses) the cash in the Exchange Fund is insufficient to fully satisfy all of the payment obligations to be made in cash by the Exchange Agent hereunder (but subject to Section 2.7), Parent shall promptly deposit cash into the Exchange Fund in an amount which is equal to the deficiency in the amount of cash required to fully satisfy such cash payment obligations. Any interest and other income resulting from such investments shall be the property of, and shall be payable to, Parent.

(g) At any time following the date that is twelve (12) months after the Effective Time, Parent shall be entitled to require the Exchange Agent to deliver to it or its designee any funds (including any interest received with respect thereto) which have been made available to the Exchange Agent and which have not been disbursed to holders of Certificates, and thereafter such holders shall be entitled to look to Parent and the Surviving Company (subject to abandoned property, escheat or other similar laws) only as general creditors thereof with respect to the Merger Consideration payable upon due surrender of their Certificate. Parent shall, or shall cause the Surviving Company to, pay all charges and expenses, including those of the Exchange Agent, in connection with the exchange of Shares for the Merger Consideration. None of Parent, the Surviving Company, the Exchange Agent or any other Person shall be liable to any Person in respect of any portion of the Exchange Fund properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. Any amounts remaining unclaimed by the Company's stockholders at such date as is immediately prior to the time at which such amounts would otherwise escheat to or become property of any Governmental Entity shall, to the extent permitted by applicable Laws, become the property of the Surviving Company, free and clear of any claims or interests of any such stockholders or their successors, assigns or personal representatives previously entitled thereto.

(h) If any Certificate shall have been lost, stolen or destroyed, upon the holder's compliance with the replacement requirements established by the Exchange Agent, including, if reasonably required by the Surviving Company, the posting by such Person of a bond in customary amount as indemnity against any claim that may be made against it or the Surviving Company with respect to such Certificate, the Exchange Agent will deliver in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable in respect thereof pursuant to this Agreement.

(i) Notwithstanding anything to the contrary in this Agreement, no holder of uncertificated Shares held through the Depository Trust Company will be required to provide a Certificate or an executed letter of transmittal to the Exchange Agent in order to receive the payment that such holder is entitled to receive pursuant to Section 2.1(a).

(j) The stock transfer books of the Company shall be closed immediately upon the Effective Time, and there shall be no further registration of transfers of Shares thereafter on the records of the Company. At or after the Effective Time, the Certificates or Book-Entry Shares shall, subject to compliance with the provisions of this Article II by the holder thereof and subject to Section 2.7, represent only the right to receive the Merger Consideration with respect to the Shares formerly represented thereby.

10

(k) Notwithstanding any other provision of this Agreement, no fractional shares of Parent Common Stock will be issued and any holder of Shares entitled to receive a fractional share of Parent Common Stock but for this Section 2.6(k) shall be entitled to receive a cash payment in lieu thereof, which payment shall be calculated by the Exchange Agent and shall represent such holder's proportionate interest in a share of Parent Common Stock based on the Parent Share Value.

Section 2.7 Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, to the extent required by the DGCL, any Shares issued and outstanding immediately prior to the Effective Time and that are held by any holder who is entitled to demand and properly demands appraisal of such Shares pursuant to, and who complies in all respects with, Section 262 of the DGCL ("Dissenting Shares") shall not be converted into the right to receive the Merger Consideration, but instead, at the Effective Time, such Dissenting Shares shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and such holder shall cease to have any rights with respect thereto, except the right to receive the fair value of such Dissenting Shares in accordance with the provisions of Section 262 of the DGCL, unless and until such holder shall have failed to perfect, or shall have effectively withdrawn or lost, such holder's right to appraisal under Section 262 of the DGCL. If any such holder fails to perfect or withdraws or loses any such right to appraisal, each such Share of such holder shall thereupon be converted into and become exchangeable only for the right to receive, as of the later of the Effective Time and the time that such right to appraisal has been irrevocably lost, withdrawn or expired, the Merger Consideration in accordance with Section 2.1(a). The Company shall serve prompt notice to Parent of any demands received by the Company for appraisal of any Shares, and, prior to the Effective Time, Parent shall have the right to participate in any negotiations and proceedings with respect to any such demands and, for the avoidance of doubt, control the negotiations and proceedings after the Effective Time. The Company shall not, without the prior consent of Parent (which consent shall not be unreasonably withheld, conditioned or delayed), make any payment with respect to, or settle, any such demands.

Section 2.8 Withholding. Each of the Exchange Agent, the Surviving Company, the Merger Subs and Parent shall be entitled to deduct and withhold, or cause to be deducted and withheld, from any portion of the consideration otherwise payable pursuant to this Agreement to any holder of Shares, or other payment otherwise payable pursuant to this Agreement, such amounts as the Exchange Agent, the Surviving Company, the Merger Subs or Parent, as the case may be, is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of any other Tax Law, and the amounts so withheld and paid over to the appropriate taxing authority by the Exchange Agent, the Surviving Company, the Merger Subs or Parent, as the case may be, shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made by the Exchange Agent, the Surviving Company, the Merger Subs or Parent, as the case may be.

Nothing contained in this Agreement shall give Parent, directly or indirectly, the right to control or direct the Company's or its Subsidiaries' operations prior to the Effective Time, and nothing contained in this Agreement shall give the Company, directly or indirectly, the right to control or direct Parent's or its Subsidiaries' operations prior to the Effective Time. Prior to the Effective Time, each of the Company and Parent, as applicable, shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its and its Subsidiaries' respective operations.

Section 5.4 Solicitation of Transactions; Recommendation.

(a) Except as expressly permitted by this Section 5.4, the Company agrees that neither it nor any of its Subsidiaries shall, and that it shall cause its and their respective officers, directors, employees, agents and representatives, including any investment banker, attorney or accountant retained by the Company or any of its Subsidiaries (collectively, "Representatives") not to, directly or indirectly, (i) initiate, solicit or encourage (including by providing information, provided, that any communication undertaken by the Company in the ordinary course of business and not related, directly or indirectly, to an Acquisition Proposal, the Mergers or any other similar transaction shall not, in and of itself, be deemed an action by the Company to encourage) any proposals or offers with respect to, or the making or completion of, an Acquisition Proposal, (ii) engage or participate in any negotiations or discussions (other than to state that they are not permitted to have discussions) concerning, or provide or cause to be provided any non-public information or data relating to the Company or any of its Subsidiaries in connection with, an Acquisition Proposal, (iii) waive or provide any consent under any "standstill" or similar restrictions contained in any confidentiality or other agreements to which the Company or any Subsidiary of the Company is a party that restricts the making of an Acquisition Proposal, unless the Company Board concludes in good faith (after consultation with outside legal counsel) that failing to so waive or provide consent would be inconsistent with the Company Board's exercise of its fiduciary duties to the Company's stockholders under applicable Laws, and any waiver or consent so granted shall not be deemed to be the encouragement, initiation or solicitation of an Acquisition Proposal, (iv) approve, endorse or recommend any Acquisition Proposal or (v) approve, endorse or recommend, or execute or enter

44

into any letter of intent, agreement in principle, merger agreement, acquisition agreement or other similar agreement relating to an Acquisition Proposal (other than a confidentiality agreement referred to in Section 5.4(b)(iii)(B)) (each, a "Company Acquisition Agreement"); provided, however, it is understood and agreed that any determination or action by the Company Board permitted under Section 5.4(b) or Section 5.4(c) or Section 7.1(d)(ii) shall not be deemed to be a breach of this Section 5.4(a) and any action, agreement, negotiation, discussion, communication, or transactions primarily contemplating disposing of or otherwise in connection with a Permitted Asset Disposition shall not constitute an Acquisition Proposal and shall not be deemed to be a breach of this Section 5.4(a). The Company agrees that it, its Subsidiaries and its Representatives will immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Persons conducted heretofore with respect to any Acquisition Proposal. Without limiting this Section 5.4, it is agreed that any violation of the restrictions set forth in this Section 5.4 by any Representative acting for, on behalf or at the direction of the Company, or any Subsidiary of the Company shall constitute a breach of this Section 5.4 by the Company.

(b) Notwithstanding anything to the contrary in Section 5.4(a), at any time prior to, but not after, the Company Stockholder Approval is obtained, the Company and its Subsidiaries and Representatives may participate in discussions or negotiations with, or furnish or disclose non-public information with respect to the Company and its Subsidiaries to, any Person in response to an unsolicited, bona fide written Acquisition Proposal that is submitted to the Company by such Person after the date of this Agreement and prior to obtaining the Company Stockholder Approval if, and only if, (i) the Company Board (or a duly authorized committee thereof) determines in good faith, after consultation with outside legal counsel, based on the information then available, that such Acquisition Proposal constitutes or would be reasonably expected to lead to a Superior Proposal (provided, however, that the actions of the Company Board solely in making such determination and such determination in and of itself shall not constitute an Adverse Recommendation Change, a violation of this Section 5.4 or termination of this Agreement), (ii) the Company Board (or duly authorized committee thereof) concludes in good faith (after consultation with outside legal counsel) that the failure to do so would be inconsistent with its fiduciary duties under applicable Laws (provided, however, that the actions of the Company Board solely in making such determination and such determination in and of itself shall not constitute an Adverse Recommendation Change, a violation of this Section 5.4 or termination of this Agreement), (iii) prior to participating in discussions or negotiations with, or furnishing or disclosing any non-public information to, such Person, the Company (A) notifies Parent of its receipt of such Acquisition Proposal and its intent to take such action and (B) receives from such Person an executed confidentiality agreement that is on terms not less restrictive to such Person than the provisions of the Non-Disclosure Agreement are to Parent, and (iv) as promptly as practicable after furnishing or discussing any non-public information to such Person making such Acquisition Proposal or its Representatives, the Company makes available to Parent any such non-public information concerning the Company or any of its Subsidiaries that is provided to the Person making such Acquisition Proposal or its Representatives to the extent such information was not previously provided or made available to Parent.

45

(c) Subject to the permitted actions contemplated by Section 7.1(d)(ii), neither the Company Board nor any committee thereof shall (i) withhold, withdraw, modify or qualify, or propose publicly to withhold, withdraw, modify or qualify, the Recommendation, in each case, in a manner adverse to Parent, Merger Sub I or Merger Sub II, (ii) except as permitted by this Section 5.4, fail to include the Recommendation in the Proxy Statement/Prospectus, (iii) if a tender or exchange offer for shares of capital stock of the Company that constitutes an Acquisition Proposal is commenced, fail to recommend against acceptance of such tender or exchange offer by the stockholders of the Company (including by taking no position with respect to the acceptance of such tender or exchange offer by the stockholders of the Company) within five (5) Business Days after commencement thereof pursuant to Rule 14d-2 under the Exchange Act or (iv) approve, authorize or recommend or otherwise declare advisable, or propose publicly to approve, authorize or recommend or otherwise publicly declare advisable, any Acquisition Proposal or Company Acquisition Agreement (any of such actions, an "Adverse Recommendation Change"). Notwithstanding anything to the contrary in this Section 5.4, at any time prior to, but not after obtaining the Company Stockholder Approval, the Company Board may effect an Adverse Recommendation Change with respect to an Acquisition Proposal if, and only if, (A) such Acquisition Proposal was not solicited by the Company or caused by the Company to have been solicited, in each case, following the date of this Agreement in violation of Section 5.4, (B) the Company provides Parent with a written notice indicating that the Company, acting in good faith, believes that such Acquisition Proposal constitutes a Superior Proposal and, therefore, plans to conduct a meeting of the Company Board for the purpose of considering whether such Acquisition Proposal constitutes a Superior Proposal, which notice shall be delivered to Parent at least five (5) Business Days prior to the date of such meeting of the Company Board and shall also include a copy of such Acquisition Proposal (or, if made orally, a reasonable description of the material terms of such Acquisition Proposal) and the other information required by Section 5.4(d), (C) during such five (5) Business Day period the Company shall, and shall cause its Representatives to, negotiate with Parent in good faith (to the extent Parent desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that such Acquisition Proposal shall cease to constitute a Superior Proposal, (D) the Company Board makes the determination that such Acquisition Proposal (after taking into account any adjustment to the terms and conditions of this Agreement proposed by Parent in response to such proposal) constitutes a Superior Proposal and (E) the Company Board concludes in good faith, after consultation with outside legal counsel, based on the information then available that failing to make an Adverse Recommendation Change would violate its fiduciary duties to the Company's stockholders under applicable Laws. Upon any amendment to the financial terms or any other material amendment of an Acquisition Proposal, the Company shall promptly (and in any event within twenty-four (24) hours) provide a new notice to Parent describing such amendment and the obligations set forth in clauses (C) and (D) of this Section 5.4(c) shall continue for at least two (2) Business Days after delivery to Parent of such notice (and, if necessary, the Company Board meeting shall be postponed to accommodate such additional negotiation period).

(d) The Company promptly (and in any event within twenty-four (24) hours) shall advise Parent orally and in writing of (i) any written Acquisition Proposal, (ii) any written request for non-public information relating to the Company or its Subsidiaries, other than requests for information not reasonably expected to be related to an Acquisition Proposal and (iii) any written inquiry or request for discussion or negotiation regarding an Acquisition Proposal, including, in each case, the identity of the Person making any such Acquisition Proposal, inquiry or request and a copy of any such Acquisition Proposal, inquiry or request (or, if made orally, a reasonable description of the material terms of any such Acquisition Proposal, inquiry or request).

46

(e) Nothing set forth in this Agreement shall prevent the Company or the Company Board from (i) taking and disclosing to its stockholders a position contemplated by Rule 14e-2(a) and Rule 14d-9 promulgated under the Exchange Act (or any similar communication to shareholders in connection with the making or amendment of a tender offer or exchange offer) or from (ii) making any disclosure to the Company's stockholders if, in the good faith judgment of the Company Board, after consultation with outside legal counsel and based on the information then available, failure to disclose such information would violate its obligations under applicable Law; provided, that any disclosure permitted under this Section 5.4(e) shall be deemed, subject to the last sentence of this Section 5.4(e), an Adverse Recommendation Change unless it includes either an express rejection of the Acquisition Proposal or an express reaffirmation of the Recommendation. A "stop, look and listen" or similar public communication contemplated by Rule 14d-9(f) shall not be deemed to be an Adverse Recommendation Change for purposes of this Agreement.

(f) As used in this Agreement:

(i) "Acquisition Proposal" means any inquiry, proposal or offer from any Person or group of Persons other than Parent or one of its Subsidiaries for (A) a merger, reorganization, consolidation, tender offer, exchange offer, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving an acquisition of the Company or any Subsidiary or Subsidiaries of the Company whose business constitutes 20% or more of the net revenues, net income or assets of the Company and its Subsidiaries, taken as a whole (for the twelve (12)-month period ending on the last day of the Company's most recently completed fiscal quarter) or (B) the acquisition in any manner, directly or indirectly, of over 20% of the equity securities or consolidated total assets of the Company and its Subsidiaries, in each case other than the Mergers and the other transactions contemplated by this Agreement, other than any inquiry, proposal or offer relating to a Permitted Asset Disposition.

(ii) "Superior Proposal" means any bona fide, written Acquisition Proposal that the Company did not solicit or cause to be solicited following the date of this Agreement in violation of this Section 5.4 (A) on terms which the Company Board determines in good faith, after consultation with the Company's outside legal counsel and financial advisors, to be more favorable from a financial point of view to the holders of Shares than the Mergers and the other transactions contemplated by this Agreement (including any adjustment to the terms and conditions proposed by Parent in response to such proposal), taking into account all the terms and conditions of the Acquisition Proposal and all legal, financial, regulatory and other aspects of the Acquisition Proposal and the Person making the proposal and (B) that the Company Board believes is reasonably likely to be completed in accordance with its terms, taking into account all financial, regulatory, legal and other aspects of such proposal; provided, that for purposes of the definition of "Superior Proposal," the references to "20%" in the definition of Acquisition Proposal shall be deemed to be references to "50%."

47

Section 5.5 Access to Information; Confidentiality.

(a) From the date hereof to the Effective Time or the earlier termination of this Agreement, upon reasonable prior written notice, the Company shall, and shall use its reasonable best efforts to cause its Subsidiaries, officers, directors and Representatives to, afford to Parent and its Representatives reasonable access during normal business hours and upon reasonable advance notice, consistent with applicable Law, to its officers, employees, properties, offices, other facilities and books and records, and shall furnish Parent and its Representatives with all existing financial, operating and other data and information as Parent shall reasonably request in writing in order to consummate the Mergers; provided, that, Parent and its Representatives shall conduct any such activities in such a manner as to not interfere unreasonably with the business or operations of the Company. All requests for such information pursuant to this Section 5.5 shall be made through the Chief Financial Officer of the Company or such Person as he shall delegate. Notwithstanding the foregoing, any such investigation or consultation shall be conducted in such a manner as not to interfere unreasonably with the business or operations of the Company or its Subsidiaries or otherwise result in any significant interference with the prompt and timely discharge by the employees of the Company or its Subsidiaries of their normal duties. Neither the Company nor any of its Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would (i) breach any agreement with any third-party, (ii) constitute a waiver of or jeopardize the attorney-client or other legal privilege held by the Company or (iii) otherwise would reasonably be expected to violate any applicable Law; provided, however, that the Company shall provide notice to Parent of the fact that it is withholding access to information pursuant to clause (i), (ii) or (iii) of this Section 5.5(a) and use commercially reasonable efforts to cause such information to be made available in a manner that would not reasonably be expected to cause such breach, waiver or violation.

(b) Each of Parent, Merger Sub I and Merger Sub II will hold and treat and will cause its Representatives to hold and treat in confidence all documents and information concerning the Company and its Subsidiaries furnished to Parent, Merger Sub I or Merger Sub II in connection with the transactions contemplated by this Agreement in accordance with the Mutual Non-Disclosure Agreement, dated March 8, 2024, by and between Parent and the Company (the "Non-Disclosure Agreement"), which the parties agree will remain in full force and effect until the earlier of the Effective Time or the termination of this Agreement in accordance with its terms.

48

Section 5.6 Further Action; Efforts. The parties shall use reasonable best efforts to promptly take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties hereto in doing, all things necessary, proper or advisable to consummate the transactions contemplated by this Agreement. Without limiting the generality of the foregoing, each party: (i) shall make all necessary filings, registrations, declaration and other submissions (if any) and give all notices (if any) required to be made and given by such party in connection with the transactions contemplated by this Agreement, (ii) shall use reasonable best efforts to obtain all necessary and advisable actions or non-actions, waivers and consents, (if any) (pursuant to any applicable Law or Contract, or otherwise) by such party in connection with the transactions contemplated by this Agreement or for such Contract to remain in full force and effect, (iii) shall use reasonable best efforts to lift any injunction prohibiting, or any other legal bar to, the transactions contemplated by this Agreement and (iv) shall use reasonable best efforts to satisfy the conditions precedent to the consummation of the transactions contemplated by this Agreement.

Section 5.7 Registration Statement; Proxy Statement.

(a) As promptly as reasonably practicable after the date of this Agreement, (i) Parent and the Company shall prepare and file with the SEC a joint proxy statement to be sent to the holders of Shares relating to the Company Stockholders Meeting and the holders of shares of Parent Common Stock relating to the Parent Stockholders Meeting (as amended or supplemented from time to time, the "Proxy Statement/Prospectus"), and Parent shall prepare and file with the SEC a Registration Statement on Form S-4 (as amended or supplemented from time to time, the "Registration Statement") with the Proxy Statement/Prospectus constituting a part thereof, in connection with the issuance of shares of Parent Common Stock constituting the Company Initial Share Consideration and the Company Delayed Share Consideration (the "Parent Share Issuance"). Parent and the Company each shall use its reasonable best efforts to (i) have the Registration Statement declared effective under the Securities Act as promptly as reasonably practicable after such filing, (ii) clear the preliminary Proxy Statement/Prospectus with the SEC as promptly as reasonably practicable after the filing thereof, (iii) mail the definitive Proxy Statement/Prospectus to the holders of Shares and shares of Parent Common Stock as promptly as reasonably practicable after the Registration Statement has been declared effective under the Securities Act and (iv) maintain the effectiveness of the Registration Statement for as long as necessary to consummate the transactions contemplated by this Agreement.

(b) The Company and Parent each agrees, as to itself and its Subsidiaries, that none of the information supplied or to be supplied by it or its Subsidiaries for inclusion or incorporation by reference in (i) the Registration Statement will, at the time the Registration Statement becomes effective under the Securities Act, 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 statements therein not misleading and (ii) the Proxy Statement/Prospectus and any amendment or supplement thereto will, at the date of mailing to holders of Shares and shares of Parent Common Stock and at the time of each of the Company Stockholders Meeting and the Parent Stockholders Meeting, or any adjournment or postponement thereof, 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 statements therein, in light of the circumstances under which they were made, not misleading. Notwithstanding the foregoing, (A) the Company assumes no

49

responsibility with respect to information supplied in writing by or on behalf of Parent, Merger Sub I or Merger Sub II for inclusion or incorporation by reference in the Registration Statement or the Proxy Statement/Prospectus and (B) Parent assumes no responsibility with respect to information supplied in writing by or on behalf of the Company for inclusion or incorporation by reference in the Registration Statement or the Proxy Statement/Prospectus. The Company and Parent each agrees that all documents that each is responsible for filing with the SEC in connection with the Mergers or the other transactions contemplated by this Agreement will comply as to form in all material respects with the applicable provisions of the Securities Act and the Exchange Act, and the rules and regulations thereunder.

(c) The Company, Parent and the Merger Subs shall cooperate with each other in the preparation of the Registration Statement and the Proxy Statement/Prospectus. Each of Parent, Merger Sub I, Merger Sub II and the Company and their respective counsels shall (i) be given a reasonable opportunity to review and comment upon the Proxy Statement/Prospectus, the Registration Statement, and any other documents related to the Company Stockholders Meeting, the Parent Stockholders Meeting or the Parent Share Issuance, prior to mailing or the filing thereof with the SEC, as applicable, (ii) provide any comments thereon as promptly as reasonably practicable and (iii) consider such comments in good faith in connection with any such document. Parent shall promptly notify the Company and its counsel of the time when the Registration Statement has become effective and of the issuance of any stop order or suspension of the qualification of the shares of Parent Common Stock issuable in the Mergers for offering or sale in any jurisdiction. Further, each party shall promptly notify the other parties and their counsel of the receipt of any written comments or other material communications such party or its counsel receives from time to time from the SEC or its staff with respect to the Registration Statement or the Proxy Statement/Prospectus and shall provide the other party with copies of any written responses to and telephonic notification of any material oral responses received from the SEC or its staff by such party or its counsel with respect to the Registration Statement or the Proxy Statement/Prospectus. If, at any time prior to the time the Company Stockholder Approval or the Parent Stockholder Approval is obtained, any party shall become aware of the occurrence of any event or other circumstance that requires an amendment or supplement to the Registration Statement or the Proxy Statement/Prospectus so that the Registration Statement or the Proxy Statement/Prospectus, as applicable, does 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 statements therein, in light of the circumstances under which they were made, not misleading, then such party shall notify the other party as promptly as reasonably practicable thereafter, and Parent and the Company each shall use its reasonable best efforts to, as promptly as reasonably practicable thereafter, (A) prepare and file with the SEC such amendment or supplement and (B) mail such amendment or supplement to the holders of Shares and shares of Parent Common Stock, in each case, to the extent legally required.

(d) As promptly as reasonably practicable after the SEC advises that it has no further comments to the Proxy Statement/Prospectus and the Registration Statement is declared effective, the Company shall duly call, give notice of, convene and hold a special meeting of the holders of Shares (the "Company Stockholders Meeting") to consider and vote upon the adoption of this Agreement, including the Mergers. Subject to Section 5.4, the Company Board shall include the Recommendation in the Proxy Statement/Prospectus and, unless there has been an Adverse Change Recommendation permitted by and in accordance with Section 5.4, shall use

50

reasonable best efforts to solicit adoption of this Agreement by the holders of Shares and take all other actions necessary or advisable to secure the vote or consent of the holders of Shares required by applicable Law to obtain such approval. The Company shall keep Parent updated with respect to proxy solicitation results as reasonably requested by Parent. Once the Company Stockholders Meeting has been called and noticed, the Company shall not postpone or adjourn the Company Stockholders Meeting without the prior written consent of Parent, other than: (i) if as of the time for which the Company Stockholders Meeting is originally scheduled (as set forth in the Proxy Statement/Prospectus), the Company believes in good faith that there are insufficient Shares represented (either in person or by proxy) and voting to obtain the Company Stockholder Approval or to constitute a quorum necessary to conduct the business of the Company Stockholders Meeting, (ii) to ensure that any required supplement or amendment to the Proxy Statement/Prospectus is provided to holders of Shares within a reasonable amount of time in advance of the Company Stockholders Meeting or (iii) as reasonably determined by the Company to comply with applicable Law. The Company shall use its reasonable best efforts to cooperate with Parent to hold the Company Stockholders Meeting on the same day and at the same time as the Parent Stockholders Meeting as soon as reasonably practicable after the date of this Agreement and to set the same record date for each such meeting. If the Company Board makes an Adverse Change Recommendation, it will not alter the obligation of the Company to submit this Agreement to the holders of Shares at the Company Stockholders Meeting to consider and vote upon the adoption of this Agreement, unless this Agreement shall have been terminated in accordance with its terms prior to the Company Stockholders Meeting.

(e) As promptly as reasonably practicable after the SEC advises that it has no further comments to the Proxy Statement/Prospectus and the Registration Statement is declared effective, Parent shall duly call, give notice of, convene and hold a special meeting of holders of shares of Parent Common Stock (the "Parent Stockholders Meeting") to consider and vote upon (A) an increase in the number of authorized shares of Parent Common Stock to 200 million shares of Parent Common Stock (the "Authorized Share Increase") and (B) if required by applicable Law, the Parent Share Issuance. Parent shall use its reasonable best efforts to solicit approval of the Authorized Share Increase and, if necessary to comply with applicable Law, the Parent Share Issuance by the holders of shares of Parent Common Stock and take all other actions necessary or advisable to secure the vote or consent of the holders of shares of Parent Common Stock required by applicable Law to obtain such approval. Parent shall keep the Company updated with respect to proxy solicitation results as reasonably requested by the Company. Once the Parent Stockholders Meeting has been called and noticed, Parent shall not postpone or adjourn the Parent Stockholders Meeting without the prior written consent of the Company, other than: (i) if as of the time for which the Parent Stockholders Meeting is originally scheduled (as set forth in the Proxy Statement/Prospectus), Parent believes in good faith that there are insufficient shares of Parent Common Stock represented (either in person or by proxy) and voting to approve the Authorized Share Increase and, if necessary to comply with applicable Law, the Parent Share Issuance or to constitute a quorum necessary to conduct the business of the Parent Stockholders Meeting, (ii) to ensure that any required supplement or amendment to the Proxy Statement/Prospectus is provided to holders of shares of Parent Common Stock within a reasonable amount of time in advance of the Parent Stockholders Meeting or (iii) as reasonably determined by Parent to comply with applicable Law. Parent shall use its reasonable best efforts to cooperate with the Company to hold the Parent Stockholders Meeting on the same day and at the same time as the Company Stockholders Meeting and to set the same record date for each such meeting.

51

Section 5.8 Takeover Laws. If any Takeover Law is or becomes applicable to this Agreement, the Mergers or any of the other transactions contemplated hereby, each of the Company and Parent and their respective board of directors shall use their respective reasonable best efforts to ensure that the Mergers and the other transactions contemplated hereby may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to eliminate or minimize the effect of such Takeover Law with respect to this Agreement, the Mergers and the other transactions contemplated hereby.

Section 5.9 Notification of Certain Matters. The Company and Parent shall promptly notify each other of (a)(i) any notice or other communication received by a party to this Agreement from any Governmental Entity in connection with the Mergers or the other transactions contemplated hereby or (ii) any notice or other communication received by a party to this Agreement from any Person alleging that the consent of such Person is or may be required in connection with the Mergers or the other transactions contemplated hereby if, in the case of this clause (ii), the subject matter or result of such communication would reasonably be expected to be material to the Company or the Mergers or the other transactions contemplated hereby, (b) any Action commenced or, to such party's knowledge, threatened against, relating to or involving or otherwise affecting such party or any of its Subsidiaries which relate to the Mergers or the other transactions contemplated hereby or (c) the discovery of any fact or circumstance that, or the occurrence or non-occurrence of any event the occurrence or non-occurrence of which, would cause or result in any of the conditions to the Mergers set forth in Article VI not being satisfied or satisfaction of those conditions being materially delayed in violation of any provision of this Agreement; provided, however, that the delivery of any notice pursuant to this Section 5.9 shall not (i) cure any breach of, or non-compliance with, any other provision of this Agreement or (ii) limit the remedies available to the party receiving such notice; provided, further, that failure to give prompt notice pursuant to clause (c) shall not constitute a failure of a condition to the Mergers set forth in Article VI except to the extent that the underlying fact or circumstance not so notified would standing alone constitute such a failure.

Section 5.10 Indemnification, Exculpation and Insurance.

(a) Without limiting any additional rights that any employee may have under any agreement or Company Plan, from the Effective Time through the sixth (6^th) anniversary of the date on which the Effective Time occurs, Parent shall, or shall cause the Surviving Company to, indemnify and hold harmless each present (as of the Effective Time) and former officer, director or employee of the Company and its Subsidiaries (the "Indemnified Parties"), against all claims, losses, liabilities, damages, judgments, inquiries, fines and reasonable fees, costs and expenses, including reasonable attorneys' fees and disbursements (collectively, "Costs"), incurred in connection with any Action, whether civil, criminal, administrative or investigative, arising out of or pertaining to (i) the fact that the Indemnified Party is or was an officer, director or employee of the Company or any of its Subsidiaries or (ii) matters existing or occurring at or prior to the Effective Time (including this Agreement and the transactions and actions contemplated hereby), whether asserted or claimed prior to, at or after the Effective Time, in each case, to the fullest extent and in the manner permitted by the DGCL and the Company

52

Charter and Company Bylaws as at the date hereof. In the event of any such Action, (A) each Indemnified Party shall be entitled to advancement of expenses incurred in the defense of any Action from Parent or the Surviving Company to the fullest extent and in the manner permitted by the DGCL and the Company Charter and Company Bylaws as at the date hereof; provided, that any Person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Person is not entitled to indemnification, (B) neither Parent nor the Surviving Company shall settle, compromise or consent to the entry of any judgment in any proceeding or threatened action, suit, proceeding, investigation or claim (and in which indemnification could be sought by such Indemnified Party hereunder), unless such settlement, compromise or consent includes an unconditional release of such Indemnified Party from all liability arising out of such action, suit, proceeding, investigation or claim or such Indemnified Party otherwise consents, and (C) the Surviving Company shall cooperate in the defense of any such matter.

(b) Except as may be required by applicable Law, Parent and the Company agree that all rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time and rights to advancement of expenses relating thereto now existing in favor of any Indemnified Party as provided in the certificate of incorporation or bylaws (or comparable organizational documents) of the Company and its Subsidiaries or in any indemnification agreement between such Indemnified Party and the Company or any of its Subsidiaries shall survive the Mergers and continue in full force and effect until the expiration of the applicable statute of limitations with respect to any claims against such directors or officers arising out of such acts or omissions, except as otherwise required by applicable Law, and shall not be amended, repealed or otherwise modified in any manner that would adversely affect any right thereunder of any such Indemnified Party.

(c) For a period of six (6) years from the Effective Time, Parent shall either cause to be maintained in effect the current policies of directors' and officers' liability insurance and fiduciary liability insurance maintained by the Company and its Subsidiaries or cause to be provided substitute policies or purchase or cause the Surviving Company to purchase, a "tail policy," in either case of at least the same coverage and amounts containing terms and conditions that are not less advantageous in the aggregate than such policy with respect to matters arising on or before the Effective Time; provided, however, that after the Effective Time, Parent shall not be required to pay with respect to such insurance policies in respect of any one policy year annual premiums in excess of 300% of the last annual premium paid by the Company prior to the date hereof in respect of the coverage required to be obtained pursuant hereto, but in such case shall purchase as much coverage as reasonably practicable for such amount; provided further, that if the Surviving Company purchases a "tail policy" and the coverage thereunder costs more than 300% (per coverage year) of such last annual premium, the Surviving Company shall purchase the maximum amount of coverage that can be obtained for 300% (per coverage year) of such last annual premium. At the Company's option, the Company may purchase, prior to the Effective Time, a six (6)-year prepaid "tail policy" on terms and conditions (in both amount and scope) providing substantially equivalent benefits as the current policies of directors' and officers' liability insurance and fiduciary liability insurance maintained by the Company and its Subsidiaries with respect to matters arising on or before the Effective Time, covering without limitation the transactions contemplated hereby. If such tail prepaid policy has been obtained by the Company prior to the Effective Time, then (i) Parent shall not be required to purchase or cause to be purchased any substitute policy or "tail policy," and (b) Parent shall cause such policy to be paid and maintained in full force and effect, for its full term, and cause all obligations thereunder to be honored by the Surviving Company and any successor thereof.

53

(d) Notwithstanding anything herein to the contrary, if any Action (whether arising before, at or after the Effective Time) is instituted against any Indemnified Party on or prior to the sixth (6^th) anniversary of the Effective Time, the provisions of this Section 5.10 shall continue in effect until the final disposition of such Action.

(e) The indemnification provided for herein shall not be deemed exclusive of any other rights to which an Indemnified Party is entitled, whether pursuant to Law, Contract or otherwise. The provisions of this Section 5.10 shall survive the consummation of the Mergers and, notwithstanding any other provision of this Agreement that may be to the contrary, expressly are intended to benefit, and shall be enforceable by, each of the Indemnified Parties and their respective heirs and legal representatives.

(f) In the event that the Surviving Company, Parent, or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or a majority of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Surviving Company or Parent, as the case may be, shall succeed to the obligations set forth in this Section 5.10.

Section 5.11 Public Announcements. Each of Parent, Merger Sub I and Merger Sub II, on the one hand, and the Company, on the other hand, shall, to the extent reasonably practicable, consult with each other before issuing, and give each other a reasonable opportunity to review and comment upon and consider in good faith all reasonable additions, deletions or chances suggested by the other party, any press release or other public statements with respect to this Agreement, the Mergers and the other transactions contemplated hereby and shall not issue any such press release or make any public announcement prior to such consultation and review, except as may be required by applicable Law, court process or by obligations pursuant to any listing agreement with any national securities exchange or national securities quotation system; provided, however, that the restrictions set forth in this Section 5.11 shall not apply to any release or announcement made or proposed to be made (i) following a determination by the Company Board that an Acquisition Proposal constitutes a Superior Proposal or (ii) following an Adverse Recommendation Change. Parent and the Company agree that the press release announcing the execution and delivery of this Agreement shall be a joint release of Parent and the Company.

Section 5.12 Section 16 Matters.

CREDIT FACILITIES

Each Existing Advance and each other advance hereunder from time to time (each an "Advance" and, collectively, the "Advances") shall be evidenced by a single promissory note substantially in the form of Exhibit B attached hereto (the "Note"). Subject to the satisfaction of the conditions precedent set forth herein, the disbursement of each Advance hereunder on and after the Effective Date shall be made upon written notice received by Lender not later than three (3) Business Days prior to the requested Advance Date specifying the Advance Date, the amount of such Advance, the third-party provider to whom such Advance will be disbursed on behalf of Borrower, and the account of such third-party provider to which such Advance is to be disbursed, together with such supporting documentation as Lender may reasonably request. Amounts borrowed hereunder and repaid or prepaid may not be reborrowed. Notwithstanding the foregoing, the Funding Cap may be increased by the mutual written consent of Borrower and Lender.

Section 2.2 Records.

Lender shall maintain in Lender's records an account or accounts evidencing the indebtedness of Borrower hereunder, including the amounts of principal and interest payable and paid to Lender from time to time hereunder. The entries made in such account or accounts shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of Lender to maintain such account or accounts or any error therein shall not in any manner affect the obligation of Borrower to repay all outstanding principal, accrued and unpaid interest, and other amounts payable hereunder in accordance with the terms of this Agreement. In the event of any conflict between such account or accounts maintained by Lender with those maintained by Borrower pursuant to the immediately following paragraph, such account or accounts of Lender shall prevail in the absence of manifest error.

Borrower shall maintain in Borrower's records an account or accounts evidencing the indebtedness of Borrower hereunder, including the amounts of principal and interest payable and paid to Lender from time to time hereunder. The entries made in such account or accounts shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of Borrower to maintain such account or accounts or any error therein shall not in any manner affect the obligation of Borrower to repay all outstanding principal, accrued and unpaid interest, and other amounts payable hereunder in accordance with the terms of this Agreement.

Section 2.3 Interest.

The outstanding principal amount of all Advances (except for the Existing Advances) under this Agreement shall accrue interest at a rate equal to five percent (5.0%) simple interest per annum from the corresponding Advance Date, which accrued interest shall be due and payable in arrears on the Maturity Date. Interest shall be calculated on the basis of a 360-day year and charged for the actual number of days elapsed to, but excluding, the Maturity Date (or such

other date on which all principal and accrued and unpaid interest hereunder is paid in full and this Agreement, and all commitments to make Advances hereunder, is terminated). Notwithstanding the foregoing, upon the occurrence, and during the continuation, of an Event of Default, interest shall accrue on all amounts outstanding hereunder at a rate equal to the otherwise applicable interest rate at such time plus an additional one percent (1.0%) simple interest per annum.

Section 2.4 Principal Payments.

Borrower agrees to duly and punctually pay all outstanding principal and accrued and unpaid interest hereunder on the Maturity Date. Borrower may voluntarily prepay the principal outstanding under this Agreement in whole or in part at any time, without premium or penalty, together with the accrued and unpaid interest on such prepaid principal. Lender shall apply payments and prepayments under this Agreement first to accrued and unpaid interest on the principal repaid or prepaid, then to outstanding principal and thereafter to any other amounts payable under this Agreement or any other Funding Documents.

Section 2.5 Payment Mechanics.

Borrower shall make each payment hereunder to Lender in immediately available funds on or prior to the day when due, in lawful money of the United States of America, at the location of Lender specified in Section 9.3 below, or at such other place or places as Lender may designate from time to time by written notice to Borrower. If any date upon which payment is due hereunder is not a Business Day, then the payment to be made on such date shall instead be due on the next Business Day.

ARTICLE 3

SECURITY INTEREST AND COLLATERAL MATTERS

Section 3.1 Grant of Security Interest.

As collateral security for the full, prompt, complete, and final payment and performance when due (whether at stated maturity, by acceleration, or otherwise) of all of the Secured Obligations and in order to induce Lender to enter into the Funding Documents and make the Advances, Borrower hereby collaterally assigns, conveys, mortgages, pledges, and hypothecates to Lender, and hereby grants to Lender, a security interest and Lien in and on all of Borrower's right, title, and interest in, to, and under the following, whether now owned or hereafter acquired, to the extent that they consist of Program Assets (collectively, the "Collateral"):

(a) all Accounts;

(b) all Equipment, Goods, Inventory, and Fixtures;

(c) all Documents, Instruments, and Chattel Paper;

(d) all Letters of Credit and Letter-of-Credit Rights;

(e) all Investment Property;

(f) all contracts, intellectual property, and other General Intangibles, including all copyrights, trademarks, service marks, trade names, and patents;

(g) all money and all deposit accounts;

(h) all books and records relating to the Collateral; and

(i) to the extent not covered by clauses (a) through (h) of this sentence, all other assets, personal property, and rights of Borrower, whether tangible or intangible, all Proceeds and products of each of the foregoing, and all accessions to, substitutions and replacements for, and rents, profits, and products of, each of the foregoing, and any and all Proceeds of any insurance, indemnity, warranty, or guaranty payable to Borrower from time to time with respect to any of the foregoing.

Notwithstanding the foregoing, the security interest and Lien shall not extend to, and the term "Collateral" shall not include, any of the following (collectively, "Excluded Property"): (i) any permit or license or any contractual obligation entered into by Borrower, in each case permitted to be outstanding under the Merger Agreement, (A) that prohibits or requires the consent of any Person other than Borrower or an Affiliate thereof which has not been obtained as a condition to the creation by Borrower of a Lien on any right, title, or interest in such permit, license, contractual obligation, or other asset or (B) to the extent that any applicable state or federal law prohibits the creation of a Lien thereon, but only, with respect to the prohibition in (A) and (B), to the extent, and for as long as, such prohibition is not terminated or rendered unenforceable or otherwise deemed ineffective by the UCC or any other applicable law; (ii) any "intent to use" trademark applications for which a statement of use has not been filed (but only until such statement is filed) to the extent that the grant of a security interest therein would impair the validity or enforceability of such intent-to-use trademark application or the resulting trademark registration under applicable United States federal law; (iii) assets to the extent a security interest in such assets would result in material adverse tax consequences as reasonably determined by Borrower and Lender; and (iv) any Non-VISTA Assets; provided, however, "Excluded Property" shall not include any proceeds, products, substitutions, or replacements of Excluded Property (unless such proceeds, products, substitutions, or replacements would otherwise themselves constitute Excluded Property).

Section 3.2 Financing Statements.

Borrower hereby irrevocably authorizes Lender at any time and from time to time to file in any relevant jurisdiction any financing statements (including fixture filings) and amendments thereto that contain the information required by Article 9 of the UCC of each applicable jurisdiction for the filing of any financing statement or amendment relating to the Collateral, including (i) whether Borrower is an organization, the type of organization, and any organizational identification number issued to Borrower, and (ii) any financing or continuation statements or other documents for the purpose of perfecting, confirming, continuing, enforcing, or protecting the security interest granted by Borrower hereunder, without the signature of Borrower where permitted by law, including the filing of a financing statement describing the Collateral as "all assets now owned or hereafter acquired by Borrower or in which Borrower otherwise has

rights, and all proceeds of the foregoing." Borrower agrees to provide all information described in the immediately preceding sentence to Lender promptly upon request by Lender. Lender may, with prior written notice to Borrower, also file with the United States Patent and Trademark Office and the United States Copyright Office (and any successor office and any similar office in any United States state or other country) this Agreement, an intellectual property security agreement, or other documents for the purpose of perfecting, confirming, continuing, enforcing, or protecting the security interest granted by Borrower hereunder, without the signature of Borrower where permitted by law, and naming Borrower as debtor and Lender as secured party.

Section 3.3 Further Assurances as to Security Matters.

Borrower shall take such further actions, and execute and/or deliver to Lender such additional financing statements, amendments, assignments, agreements, supplements, powers, and instruments, as may be deemed necessary or appropriate in order to perfect, preserve, and protect the security interest in the Collateral as provided herein and the rights and interests granted to Lender hereunder, and enable Lender to exercise and enforce its rights, powers, and remedies hereunder with respect to any Collateral, including the filing of any financing statements, continuation statements, and other documents under the UCC (or other similar laws) in effect in any jurisdiction with respect to the security interest created hereby, and the filing of intellectual property security agreements with the United States Patent and Trademark Office and the United States Copyright Office, all in form reasonably satisfactory to Lender in such offices wherever required by law to perfect, continue, and maintain a valid, enforceable, first-priority security interest in the Collateral as provided herein and to preserve the other rights and interests granted to Lender hereunder, as against third parties, with respect to the Collateral. Without limiting the generality of the foregoing, but subject to applicable law, Borrower shall make, execute, endorse, acknowledge, file, or refile and/or deliver to Lender from time to time upon reasonable request by Lender such lists, schedules, descriptions, and designations of the Collateral, statements, copies of warehouse receipts, bills of lading, documents of title, vouchers, invoices, schedules, confirmatory assignments, supplements, additional security agreements, conveyances, financing statements, transfer endorsements, powers of attorney, certificates, reports, and other assurances or instruments as Lender may reasonably request. If an Event of Default has occurred and is continuing, Lender may institute and maintain, in its own name or in the name of Borrower, such suits and proceedings as Lender may deem necessary or expedient to prevent any impairment of the security interest in, or the perfection thereof, in the Collateral. Each of Borrower and Lender shall be responsible for their own costs and expenses associated with the foregoing.

Borrower hereby represents and warrants to Lender on the date hereof and on each Advance Date as follows:

conducted, and (iii) is duly qualified or licensed to do business and is in good standing (with respect to jurisdictions that recognize such concept) in each jurisdiction in which the nature of its business or the ownership, leasing, or operation of its properties makes such qualification or licensing necessary, except for any such failures to be so organized, existing, and in good standing, to have such power and authority, or to be so qualified or licensed or in good standing as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

Section 4.2 Power and Authority; Enforceability; Consents; No Conflict.

Borrower has all necessary corporate power and authority to execute, deliver, and perform its obligations under this Agreement and the other Funding Documents to which it is a party, and has taken all necessary entity action to authorize the execution, delivery, and performance of the Funding Documents to which it is a party. The execution, delivery, and performance of this Agreement and the other Funding Documents by Borrower and the consummation by Borrower of the transactions contemplated hereby and thereby have been duly authorized by all necessary corporate action on the part of Borrower and no other corporate proceedings on the part of Borrower are necessary to approve this Agreement or the other Funding Documents or to consummate the transactions contemplated hereby and thereby. This Agreement and the other Funding Documents to be executed and delivered by Borrower on the date hereof have been duly executed and delivered by Borrower and, assuming the due authorization, execution, and delivery by the other parties thereto, constitute valid and binding obligations of Borrower, enforceable against Borrower in accordance with their terms (except to the extent that enforceability may be limited by applicable bankruptcy, insolvency, moratorium, reorganization, or similar Laws affecting the enforcement of creditors' rights generally or by general principles of equity). No consent or authorization of, filing with, notice to, or other act by or in respect of any Governmental Entity or any other Person is required to be made or obtained in connection with the execution, delivery, performance, validity, or enforceability of this Agreement or any other Funding Document by or against Borrower, other than (i) registrations, consents, approvals, notices, or other actions that have been obtained and that are still in full force and effect, (ii) filings and recordings with respect to the Collateral to be made or otherwise delivered to Lender for filing or recordation from time to time as contemplated by the terms of the Funding Documents, and (iii) such consents, authorizations, filings, notices, or other acts of any Governmental Entity or any other Person the failure of which to make or obtain would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. This Agreement and the other Funding Documents do not violate the terms of or otherwise conflict with (a) the Merger Agreement or (b) except as would not reasonably be expected to result in a Material Adverse Effect, any other Contract binding on Borrower or any Collateral.

Section 4.3 Actions, Suits, Etc.

Except as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, there is no action, suit, investigation, or proceeding pending or, to the knowledge of Borrower, threatened, against or affecting Borrower or any of its assets.

Section 4.4 Information.

No information or report furnished by Borrower to Lender in connection with the negotiation of this Agreement or the other Funding Documents contained any material misstatement of fact or omitted to state a material fact or any fact necessary to make the statements contained therein, in light of the circumstances under which they were made, not misleading.

Exhibit 99.1

TuHURA Biosciences, Inc. Enters into Definitive Merger Agreement to Acquire

Kineta, Inc.

Opportunistic acquisition adds Phase 2 novel checkpoint inhibitor

(KVA12123) to TuHURA's late stage pipeline

Targeting Phase 2a/b trial with KVA12123 in mutated NPM1 AML in 2025

Cross product and technology synergies build on TuHURA's therapeutic focus

on overcoming primary and acquired resistance to cancer immunotherapy

Proposed Transaction expected to close in Q1 2025

TAMPA, FL and SEATTLE, WA, December 12, 2024 - TuHURA Biosciences, Inc. (Nasdaq: HURA) ("TuHURA"), a Phase 3 registration-stage immune-oncology company developing novel technologies to overcome resistance to cancer immunotherapy, and Kineta, Inc. (OTC Pink: KANT) ("Kineta"), a clinical-stage biotechnology company focused on the development of novel immunotherapies in oncology that address cancer immune resistance, today announced that they have entered into a definitive merger agreement in which TuHURA would acquire Kineta, including the rights to Kineta's novel KVA12123 antibody, for a combination of cash and shares of TuHURA common stock via a merger transaction (the "Proposed Transaction").

"We are pleased to have entered into this definitive agreement with Kineta, which represents the culmination of the Exclusivity and Right of First Offer Agreement that TuHURA and Kineta entered into in July 2024. Our strategy of providing Kineta this past summer with a $5 million exclusivity fee to restart and finish their Phase 1 monotherapy and combination with pembrolizumab trial demonstrated our view that the PK/PD profile would position KVA12123 as a potential best-in-class V-domain Ig suppressor of T-cell activation (VISTA)-inhibiting antibody. We believe the real potential for this class of checkpoint inhibitors resides in the treatment of blood related cancers. The data presented at the December 2024 ASH meeting indicates a strong correlation between NPM1 mutations (mNPM1) and elevated VISTA expression, particularly in the context of acute myeloid leukemia (AML), where high VISTA levels on leukemia cells, associated with mNPM1, can potentially contribute to immune evasion and disease progression impacting their treatment response. Given mNPM1 drives leukemogenesis through menin, and the introduction of menin inhibitors improving treatment responses in mNPM1-associated AML, a combination with a VISTA-inhibiting antibody could be the next step in improving response rates in AML," commented James Bianco, M.D., President and Chief Executive Officer of TuHURA.

KVA12123 is a VISTA-blocking immunotherapy in development as a monoclonal antibody infusion drug dosed every two-week cycles. It is completing two clinical trials both as a monotherapy and in combination with Merck's anti-PD1 therapy, KEYTRUDA^® (pembrolizumab), in patients with advanced treatment-refractory solid tumors. Competitive therapies targeting VISTA have demonstrated either poor monotherapy anti-tumor activity in preclinical models or induction of cytokine release syndrome (CRS) in human clinical trials. Through the combination of unique epitope binding and an optimized IgG1 Fc region, KVA12123 demonstrates strong monotherapy tumor growth inhibition in preclinical models without evidence of CRS in clinical trial participants. KVA12123 has been shown to de-risk the VISTA target and provides a novel approach to address immune suppression in the tumor microenvironment (TME) with a mechanism of action that is differentiated and complementary with T cell focused therapies. KVA12123 may be an effective immunotherapy for many types of cancer and represents the introduction of a new class of checkpoint inhibitors.

VISTA is a negative immune checkpoint that suppresses T cell function in a variety of solid tumors. High VISTA expression in tumor correlates with poor survival in cancer patients and has been associated with a lack of response to other immune checkpoint inhibitors. Blocking VISTA induces an efficient polyfunctional immune response to address immunosuppression and drives anti-tumor responses.

KVA12123 has completed enrollment in its monotherapy arm, demonstrating safety at its highest dose level (1000mg). Kineta anticipates completion of enrollment in the combination therapy arm where KVA12123 is administered with Merck's anti-PD1 therapy, KEYTRUDA^® (pembrolizumab). Initial results were reported earlier this year at the American Association of Cancer Research (AACR) Annual Meeting 2024 and at the Society for Immunotherapy of Cancer (SITC) meeting, supporting best-in-class profile.

"Following a thorough review of exploring strategic alternatives for Kineta and the discussions held with TuHURA over the course of the past several months, we believe this acquisition by TuHURA maximizes shareholder value and provides an exciting development path forward for KVA12123. We believe KVA12123 has multiple synergies with both of TuHURA's IFx and Delta receptor antibody-drug conjugate (ADC) and peptide drug conjugate (PDC) technologies and that a TuHURA acquisition will provide the necessary resources to advance KVA12123 through its clinical development, maximizing value for Kineta's shareholders," said Craig W. Philips, President of Kineta. "In addition to the TuHURA transaction, Kineta is continuing to pursue partnership opportunities for some of its other non-KVA12123-related products and technologies prior to the close of the TuHURA transaction."

About the Proposed Transaction

Under the terms of the merger agreement, upon the completion of the Proposed Transaction, Kineta stockholders will receive their pro rata share (based on the number of Kineta fully diluted shares held by them) of aggregate merger consideration consisting of a combination of cash and shares of TuHURA common stock. The cash component of the aggregate merger consideration will be a base cash amount of $9,005,000 (consisting of a value of $15,000,000 minus the $5,995,000 advanced to Kineta under the Exclusivity and Right of First Offer Agreement) less the sum of Kineta's working capital deficit at the closing of the Proposed Transaction and any working

capital loans made by TuHURA to Kineta between the signing of the merger agreement and closing of the Proposed Transaction. The share component of the aggregate merger consideration will consist of an aggregate of up to approximately 3,476,568 shares of TuHURA common stock, subject to a six-month holdback of approximately 869,142 of such shares to satisfy certain additional liabilities of the closing date that may be identified after the closing. As additional merger consideration, Kineta stockholders will be entitled to receive their pro rata share of certain payments that Kineta may receive after the closing from the potential pre-closing sale by Kineta of certain non-KVA12123 products and technologies.

In connection with the merger agreement, TuHURA and Kineta entered into a Clinical Trial Funding Agreement under which TuHURA agreed to continue to fund clinical trial expenses for KVA12123 in an amount of up to $900,000, which may be increased upon mutual agreement. The merger agreement also provides that Kineta may request the extension of up to $2,000,000 in working capital loans from TuHURA, $1,750,000 of which will be contingent on the completion of a financing transaction by TuHURA.

The merger agreement has been unanimously approved by the boards of directors of both companies and is subject to Kineta stockholder approval. The completion of the Proposed Transaction is also subject to the satisfaction or waiver of certain other conditions, such as the approval by TuHURA's stockholders of an increase in the number of authorized shares of TuHURA common stock, Kineta's working capital deficit not exceeding $12,000,000 at the time of closing, the effectiveness of a registration statement on Form S-4 registering the shares of TuHURA common stock issuable to the Kineta stockholders in the Proposed Transaction, and other customary closing conditions. The Proposed Transaction is currently expected to close in the first quarter of 2025.

About TuHURA Biosciences, Inc.

TuHURA Biosciences, Inc. (Nasdaq: HURA) is a Phase 3 registration-stage immuno-oncology company developing novel technologies to overcome primary and acquired resistance to cancer immunotherapy, two of the most common reasons cancer immunotherapies fail to work or stop working in the majority of patients with cancer.

TuHURA's lead innate immune agonist candidate, IFx-2.0, is designed to overcome primary resistance to checkpoint inhibitors. TuHURA is preparing to initiate a single randomized placebo-controlled Phase 3 registration trial of IFx-2.0 administered as an adjunctive therapy to Keytruda^® (pembrolizumab) in first line treatment for advanced or metastatic Merkel Cell Carcinoma.

In addition to its innate immune agonist candidates, TuHURA is leveraging its Delta receptor technology to develop first-in-class bi-specific ADCs and PDCs targeting Myeloid Derived Suppressor Cells to inhibit their immune-suppressing effects on the TME to prevent T cell exhaustion and acquired resistance to checkpoint inhibitors and cellular therapies.
