G. Concurrently with the execution and delivery of this Agreement and as a condition and inducement to the Company’s willingness to enter into this Agreement, (a) the officers, directors and stockholders of Parent listed in Section A-1 of the Parent Disclosure Schedule (solely in their capacity as stockholders of Parent), which represent at least twenty-five percent (25%) of the voting securities of Parent, are executing support agreements in favor of the Company in substantially the form attached hereto as Exhibit B-2 (the “Parent Stockholder Support Agreement”) and (b) the officers, directors and stockholders of Parent listed in Section A-2 of the Parent Disclosure Schedule (solely in their capacity as stockholders of Parent) are executing lock-up agreements in substantially the form attached hereto as Exhibit C-2 (the “Parent Lock-Up Agreement”).

AGREEMENT

The Parties, intending to be legally bound, agree as follows:

Section 1. DESCRIPTION OF TRANSACTION

1.1 The Merger. Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time, Merger Sub shall be merged with and into the Company, and the separate existence of Merger Sub shall cease. The Company will continue as the surviving corporation in the Merger (the “Surviving Corporation”).

1.2 Effects of the Merger. The Merger shall have the effects set forth in this Agreement, the Certificate of Merger and in the applicable provisions of the DGCL. As a result of the Merger, the Company will become a wholly owned subsidiary of Parent.

1.3 Closing; Effective Time. Unless this Agreement is earlier terminated pursuant to the provisions of Section 9.1, and subject to the satisfaction or waiver of the conditions set forth in Sections 6, 7 and 8, the consummation of the Merger (the “Closing”) shall take place remotely as promptly as practicable (but in no event later than the second (2nd) Business Day following the satisfaction or waiver of the last to be satisfied or waived of the conditions set forth in Sections 6, 7 and 8, other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of each of such conditions), or at such other time, date and place as Parent and the Company may mutually agree in writing. The date on which the Closing actually takes place is referred to as the “Closing Date.” At the Closing, the Parties shall cause the Merger to be consummated by executing and filing with the Secretary of State of the State of Delaware a certificate of merger with respect to the Merger, satisfying the applicable requirements of the DGCL and in a form reasonably acceptable to Parent and the Company (the “Certificate of Merger”). The Merger shall become effective at the time of the filing of such Certificate of Merger with the Secretary of State of the State of Delaware or at such later time as may be specified in such Certificate of Merger with the consent of Parent and the Company (the time as of which the Merger becomes effective being referred to as the “Effective Time”).

1.4 Certificate of Incorporation and Bylaws; Directors and Officers. At the Effective Time:

(a) the certificate of incorporation of the Surviving Corporation shall be amended and restated in its entirety to read identically to the certificate of incorporation of Merger Sub as in effect immediately prior to the Effective Time, until thereafter amended as provided by the DGCL and such certificate of incorporation; provided, however, that at or immediately prior to the Effective Time, the Surviving Corporation shall file an amendment to its certificate of incorporation to change the name of the Surviving Corporation to ARS Subsidiary, Inc. or such other name as shall be mutually agreed upon by Parent and the Company prior to filing such amendment;

(b) the certificate of incorporation of Parent shall be identical to the certificate of incorporation of Parent immediately prior to the Effective Time, until thereafter amended as provided by the DGCL and such certificate of incorporation; provided, however, that at or immediately prior to the Effective Time, Parent shall file an amendment to its certificate of incorporation to (i) change the name of Parent to ARS Pharmaceuticals, Inc. and (ii) make such other changes as shall be mutually agreed upon by Parent and the Company prior to filing such amendment;

(c) the bylaws of the Surviving Corporation shall be amended and restated in their entirety to read identically to the bylaws of Merger Sub as in effect immediately prior to the Effective Time (except that the name of the Surviving Corporation in such bylaws shall reflect the name identified in Section 1.4(a)), until thereafter amended as provided by the DGCL and such bylaws;

(d) the directors and officers of Parent, each to hold office in accordance with the certificate of incorporation and bylaws of Parent, shall be as set forth in Section 5.13 after giving effect to the provisions of Section 5.13, or such other persons as shall be mutually agreed upon by Parent and the Company; and

(e) the directors and officers of the Surviving Corporation, each to hold office in accordance with the certificate of incorporation and bylaws of the Surviving Corporation, shall be determined prior to Closing by the Company.

1.5 Conversion of Shares.

(a) At the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Merger Sub, the Company or any stockholder of the Company or Parent:

(i) any shares of Company Capital Stock held as treasury stock by the Company or held or owned by Parent, Merger Sub or any Subsidiary of Parent or the Company immediately prior to the Effective Time shall be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor; and

(ii) subject to Section 1.5(c), each share of Company Capital Stock outstanding immediately prior to the Effective Time (excluding shares to be canceled pursuant to Section 1.5(a)(i) and excluding Dissenting Shares), after giving effect to the Preferred Stock Conversion, shall be automatically converted solely into the right to receive a number of shares of Parent Common Stock equal to the Exchange Ratio (the “Merger Consideration”).

(b) If any shares of Company Capital Stock outstanding immediately prior to the Effective Time are unvested or are subject to a repurchase option or a risk of forfeiture under any applicable restricted stock purchase agreement or other similar agreement with the Company, then the shares of Parent Common Stock issued in exchange for such shares of Company Capital Stock at the Effective Time will to the same extent be unvested and subject to the same repurchase option or risk of forfeiture, and such shares of Parent Common Stock shall accordingly be marked with appropriate legends. The Company shall use commercially reasonable efforts to take all actions that may be reasonably necessary to ensure that, from and after the Effective Time, Parent is entitled to exercise any such repurchase option or other right set forth in any such restricted stock purchase agreement or other agreement in accordance with its terms.

(c) No fractional shares of Parent Common Stock shall be issued in connection with the Merger, no certificates or scrip for any such fractional shares shall be issued and no cash shall be paid for any such fractional shares. Any fractional shares of Parent Common Stock that a holder of Company Capital Stock would otherwise be entitled to receive shall be aggregated with all fractional shares of Parent Common Stock issuable to such holder and any remaining fractional shares shall be rounded up to the nearest whole share.

(d) All Company Options outstanding immediately prior to the Effective Time under the Company Plan shall be treated in accordance with Section 5.5(a).

(e) All Company Warrants outstanding immediately prior to the Effective Time shall be treated in accordance with Section 5.5(c).

(f) Each share of common stock, $0.001 par value per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and exchanged for one validly issued, fully paid and nonassessable share of common stock, $0.001 par value per share, of the Surviving Corporation. Each stock certificate of Merger Sub evidencing ownership of any such shares shall, as of the Effective Time, evidence ownership of such shares of common stock of the Surviving Corporation.

(g) If, between the time of calculating the Exchange Ratio and the Effective Time, the outstanding shares of Company Capital Stock or Parent Common Stock shall have been changed into, or exchanged for, a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares or other like change, the Exchange Ratio shall, to the extent necessary, be equitably adjusted to reflect such change to the extent necessary to provide the holders of Company Capital Stock, Parent Common Stock, Company Options and Company Warrants with the same economic effect as contemplated by this Agreement prior to such stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares or other like change; provided, however, that nothing herein will be construed to permit the Company or Parent to take any action with respect to Company Capital Stock or Parent Common Stock, respectively, that is prohibited or not expressly permitted by the terms of this Agreement.

1.6 Calculation of Parent Net Cash.

(a) For the purposes of this Agreement, the “Anticipated Closing Date” shall be the date, as agreed upon by Parent and the Company at least ten (10) calendar days prior to the Parent Stockholders’ Meeting, to be the anticipated date for Closing. At least five (5) calendar days prior to the Anticipated Closing Date, Parent shall deliver to the Company a schedule (the “Net Cash Schedule”) setting forth, in reasonable detail, Parent’s good faith, estimated calculation of Parent Net Cash (the “Net Cash Calculation”) as of the Anticipated Closing Date, prepared and certified by an executive officer of Parent. Parent shall make available to the Company the work papers and back-up materials used or useful in preparing the Net Cash Schedule, as reasonably requested by the Company.

(b) Within three (3) calendar days after delivery of the Net Cash Schedule (the “Response Date”), the Company will have the right to dispute any part of the Net Cash Schedule by delivering a written notice to that effect to Parent (a “Dispute Notice”). Any Dispute Notice shall identify in reasonable detail the nature of any proposed revisions to the Net Cash Calculation.

(c) If on or prior to the Response Date, the Company (i) notifies Parent in writing that it has no objections to the Net Cash Calculation or (ii) fails to deliver a Dispute Notice as provided in Section 1.6(b) then the Net Cash Calculation as set forth in the Net Cash Schedule shall be deemed to have been finally determined for purposes of this Agreement and to represent Parent Net Cash at the Anticipated Closing Date for purposes of this Agreement.

(d) If the Company delivers a Dispute Notice on or prior to the Response Date, then Representatives of both Parties shall promptly meet and attempt in good faith to resolve the disputed item(s) and negotiate an agreed-upon determination of Parent Net Cash, which agreed upon Parent Net Cash amount shall be deemed to have been finally determined for purposes of this Agreement and to represent Parent Net Cash at the Anticipated Closing Date for purposes of this Agreement.

(e) If Parent and the Company are unable to negotiate an agreed-upon determination of Parent Net Cash at the Anticipated Closing Date pursuant to Section 1.6(d) within three (3) calendar days after delivery of the Dispute Notice (or such other period as Parent and the Company may mutually agree upon), then Parent and the Company shall jointly select an independent auditor of recognized national standing (the “Accounting Firm”) to resolve any remaining disagreements as to the Net Cash Calculation. Parent shall promptly deliver to the Accounting Firm the work papers and back-up materials used in preparing the Net Cash Schedule, and Parent and the Company shall use commercially reasonable efforts to cause the Accounting Firm to make its determination within ten (10) calendar days of accepting its selection. The Company and Parent shall be afforded the opportunity to present to the Accounting Firm any material related to the unresolved disputes and to discuss the issues with the Accounting Firm; provided, however, that no such presentation or discussion shall occur without the presence of a Representative of each of the Company and Parent. The determination of the Accounting Firm shall be limited to the disagreements submitted to the Accounting Firm. The determination of the amount of Parent Net Cash made by the Accounting Firm shall be deemed to have been finally determined for purposes of this Agreement and to represent Parent Net Cash at the Anticipated Closing Date for purposes of this Agreement, and the Parties shall delay the Closing until the resolution of the matters described in this Section 1.6(e). The fees and expenses of the Accounting Firm shall be allocated between Parent and the Company in the same proportion that the disputed amount of Parent Net Cash that was unsuccessfully disputed by such Party (as finally determined by the Accounting Firm) bears to the total disputed amount of Parent Net Cash (and for the avoidance of doubt, such fees and expenses of the Accounting Firm allocated to Parent shall reduce Parent Net Cash). If this Section 1.6(e) applies as to the determination of Parent Net Cash at the Anticipated Closing Date described in Section 1.6(a), upon resolution of the matter in accordance with this Section 1.6(e), the Parties shall not be required to determine Parent Net Cash again even though the Closing Date may occur later than the Anticipated Closing Date, except that either Party may request a re-determination of Parent Net Cash if the Closing Date is more than five (5) Business Days after the Anticipated Closing Date.

1.7 Closing of the Company’s Transfer Books. At the Effective Time: (a) all shares of Company Capital Stock outstanding immediately prior to the Effective Time shall be treated in accordance with Section 1.5(a), and all holders of certificates or book-entry shares representing shares

of Company Capital Stock that were outstanding immediately prior to the Effective Time shall cease to have any rights as stockholders of the Company; and (b) the stock transfer books of the Company shall be closed with respect to all shares of Company Capital Stock outstanding immediately prior to the Effective Time. No further transfer of any such shares of Company Capital Stock shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, a valid certificate previously representing any shares of Company Capital Stock outstanding immediately prior to the Effective Time (a “Company Stock Certificate”) is presented to the Exchange Agent or to the Surviving Corporation, such Company Stock Certificate shall be canceled and shall be exchanged as provided in Sections 1.5 and 1.8.

1.8 Surrender of Certificates.

(a) On or prior to the Closing Date, Parent and the Company shall agree upon and select a reputable bank, transfer agent or trust company to act as exchange agent in the Merger (the “Exchange Agent”). At the Effective Time, Parent shall deposit with the Exchange Agent evidence of book-entry shares representing the Parent Common Stock issuable pursuant to Section 1.5(a). The Parent Common Stock so deposited with the Exchange Agent, together with any dividends or distributions received by the Exchange Agent with respect to such shares, are referred to collectively as the “Exchange Fund.”

(b) Promptly after the Effective Time, the Parties shall cause the Exchange Agent to mail to the Persons who were record holders of shares of Company Capital Stock that were converted into the right to receive the Merger Consideration: (i) a letter of transmittal in customary form and containing such provisions as Parent may reasonably specify (including a provision confirming that delivery of Company Stock Certificates shall be effected, and risk of loss and title to Company Stock Certificates shall pass, only upon proper delivery of such Company Stock Certificates to the Exchange Agent); and (ii) instructions for effecting the surrender of Company Stock Certificates in exchange for shares of Parent Common Stock. Holders of Company Preferred Stock shall surrender Company Stock Certificates representing the shares of Company Preferred Stock that were converted in connection with the Preferred Stock Conversion. Upon surrender of a Company Stock Certificate to the Exchange Agent for exchange, together with a duly executed letter of transmittal and such other documents as may be reasonably required by the Exchange Agent or Parent (including a properly completed IRS Form W-9 or the appropriate version of IRS Form W-8, as applicable): (A) the holder of such Company Stock Certificate shall be entitled to receive in exchange therefor book-entry shares representing the Merger Consideration (in a number of whole shares of Parent Common Stock) that such holder has the right to receive pursuant to the provisions of Section 1.5(a); and (B) the Company Stock Certificate so surrendered shall be canceled. Until surrendered as contemplated by this Section 1.8(b), each Company Stock Certificate shall be deemed, from and after the Effective Time, to represent only the right to receive book-entry shares of Parent Common Stock representing the Merger Consideration. If any Company Stock Certificate shall have been lost, stolen or destroyed, Parent may, in its reasonable discretion and as a condition precedent to the delivery of any shares of Parent Common Stock, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an applicable affidavit with respect to such Company Stock Certificate that includes an obligation of such owner to indemnify Parent against any claim suffered by Parent related to the lost, stolen or destroyed Company Stock Certificate as Parent may reasonably request. In the event of a transfer of ownership of a Company Stock Certificate that is not registered in the transfer records of the Company, payment of the Merger Consideration may be made to a Person other than the Person in whose name such Company Stock Certificate so surrendered is registered if such Company Stock Certificate shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment shall pay any transfer or other Taxes required by reason of the transfer or establish to the reasonable satisfaction of Parent that such Taxes have been paid

or are not applicable. The Merger Consideration and any dividends or other distributions as are payable pursuant to Section 1.8(c) shall be deemed to have been in full satisfaction of all rights pertaining to Company Capital Stock formerly represented by such Company Stock Certificates.

(c) No dividends or other distributions declared or made with respect to Parent Common Stock with a record date on or after the Effective Time shall be paid to the holder of any unsurrendered Company Stock Certificate with respect to the shares of Parent Common Stock that such holder has the right to receive in the Merger until such holder surrenders such Company Stock Certificate or provides an affidavit of loss, theft or destruction in lieu thereof in accordance with this Section 1.8 together with a duly executed letter of transmittal and such other documents as may be reasonably required by the Exchange Agent or Parent (at which time (or, if later, on the applicable payment date) such holder shall be entitled, subject to the effect of applicable abandoned property, escheat or similar Laws, to receive all such dividends and distributions, without interest).

(d) Any portion of the Exchange Fund that remains undistributed to holders of Company Stock Certificates as of the date that is one (1) year after the Closing Date shall be delivered to Parent upon demand, and any holders of Company Stock Certificates who have not theretofore surrendered their Company Stock Certificates in accordance with this Section 1.8 shall thereafter look only to Parent for satisfaction of their claims for Parent Common Stock and any dividends or distributions with respect to shares of Parent Common Stock.

(e) No Party to this Agreement shall be liable to any holder of any Company Stock Certificate or to any other Person with respect to any shares of Parent Common Stock (or dividends or distributions with respect thereto) or for any cash amounts delivered to any public official pursuant to any applicable abandoned property Law, escheat Law or similar Law.

(f) All shares of Parent Common Stock issued pursuant to this Agreement shall bear a legend (and Parent will make a notation on its transfer books to such effect) prominently stamped or printed thereon or the substance of which will otherwise be reflected on the books and records of the transfer agent for Parent Common Stock with respect to book-entry shares, in each case reading substantially as follows:

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT PURPOSES AND NOT WITH A VIEW TO RESALE IN CONNECTION WITH A DISTRIBUTION AND MAY NOT BE SOLD OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT FOR SUCH SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND APPLICABLE STATE SECURITIES LAWS, OR AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT.”

1.9 Appraisal Rights.

(a) Notwithstanding any provision of this Agreement to the contrary, shares of Company Capital Stock that are outstanding immediately prior to the Effective Time and which are held by stockholders who have exercised and perfected appraisal rights for such shares of Company Capital Stock in accordance with the DGCL or California Law, as applicable (collectively, the “Dissenting Shares”) shall not be converted into or represent the right to receive the Merger Consideration described in Section 1.5 attributable to such Dissenting Shares. Such stockholders shall be entitled to receive payment of the appraised value of such shares of Company Capital Stock held by them in accordance with the DGCL or California Law, as applicable, unless and until such stockholders fail to perfect or effectively withdraw or otherwise lose their appraisal rights under the DGCL or California Law, as

applicable. All Dissenting Shares held by stockholders who shall have failed to perfect or shall have effectively withdrawn or lost their right to appraisal of such shares of Company Capital Stock under the DGCL or California Law, as applicable (whether occurring before, at or after the Effective Time) shall thereupon be deemed to be converted into and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration, without interest, attributable to such Dissenting Shares upon their surrender in the manner provided in Sections 1.5 and 1.8.

(b) The Company shall give Parent prompt written notice of any demands by dissenting stockholders received by the Company, withdrawals of such demands and any other instruments served on the Company and any material correspondence received by the Company in connection with such demands, and the Company shall have the right to direct all negotiations and proceedings with respect to such demands; provided that Parent shall have the right to participate in such negotiations and proceedings. The Company shall not, except with Parent’s prior written consent, not to be unreasonably withheld, delayed or conditioned, make any payment with respect to, or settle or offer to settle, any such demands, or approve any withdrawal of any such demands or agree to do any of the foregoing.

1.10 Further Action. If, at any time after the Effective Time, any further action is determined by the Surviving Corporation to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession of and to all rights and property of the Company, then the officers and directors of the Surviving Corporation shall be fully authorized, and shall use their and its commercially reasonable efforts (in the name of the Company, in the name of Merger Sub, in the name of the Surviving Corporation and otherwise) to take such action.

1.11 Withholding.

The Company is not under any obligation, nor is it bound by any Contract pursuant to which it may become obligated, to repurchase, redeem or otherwise acquire any outstanding shares of Company Capital Stock or other securities. Section 2.6(b) of the Company Disclosure Schedule accurately and completely lists all repurchase rights held by the Company with respect to shares of Company Capital Stock (including shares issued pursuant to the exercise of stock options) and specifies which of those repurchase rights are currently exercisable and whether the holder of such shares of Company Capital Stock timely filed an election with the relevant Governmental Bodies under Section 83(b) of the Code with respect to such shares. Each share of Company Preferred Stock is convertible into one share of Company Common Stock.

(c) Except for the Company Plan, the Company does not have any stock option plan or any other plan, program, agreement or arrangement providing for any equity-based compensation for any Person. As of the date of this Agreement, the Company has reserved 5,613,278 shares of Company Common Stock for issuance under the Company Plan, of which 596,763 shares have been issued and are currently outstanding, 4,767,667 shares have been reserved for issuance upon exercise of Company Options previously granted and currently outstanding under the Company Plan, and 248,848 shares of Company Common Stock remain available for future issuance of awards pursuant to the Company Plan.

All stock option agreements evidencing outstanding Company Options are consistent with the Company’s standard form of stock option agreements. No vesting of Company Options will accelerate in connection with the closing of the Contemplated Transactions.

(d) Except for Company Warrants and the Company Options set forth in Section 2.6(c) of the Company Disclosure Schedule, there is no: (i) outstanding subscription, option, call, warrant or right (whether or not currently exercisable) to acquire any shares of the capital stock or other securities of the Company or any of its Subsidiaries; (ii) outstanding security, instrument or obligation that is or may become convertible into or exchangeable for any shares of the capital stock or other securities of the Company or any of its Subsidiaries; or (iii) condition or circumstance that could be reasonably likely to give rise to or provide a basis for the assertion of a claim by any Person to the effect that such Person is entitled to acquire or receive any shares of capital stock or other securities of the Company or any of its Subsidiaries.

The Company’s use and operation of each such leased property conforms to all applicable Laws in all material respects, and the Company has exclusive possession of each such leased property and has not granted any occupancy rights to tenants or licensees with respect to such leased property. In addition, each such leased property is free and clear of all Encumbrances other than Permitted Encumbrances.

2.13 Intellectual Property.

(a) Section 2.13(a) of the Company Disclosure Schedule identifies (i) the name of the applicant/registrant, (ii) the jurisdiction of application/registration, (iii) the application or registration number and (iv) any other co-owners, for each item of Registered IP owned in whole or in part by the Company or its Subsidiaries (the “Company Owned Registered IP”). Each of the patents and patent applications included in the Company Owned Registered IP properly identifies by name each and every inventor of the inventions claimed therein as determined in accordance with applicable Laws of the United States. Except as set forth in Section 2.13(a) of the Company Disclosure Schedule: (A) The Company Owned Registered IP is valid, enforceable and subsisting, (B) none of the Company Owned Registered IP has been misused, withdrawn, cancelled or abandoned, and (C) all application, registration, issuance, renewal and maintenance fees due for the Company Owned Registered IP having a due date on or before the date hereof have been paid in full and are current. To the Company’s Knowledge, with respect to each item of Company Owned Registered IP and each patent application from which such Company Owned Registered IP claims priority, all statements made and information presented to the applicable patent office by or on behalf of the Company or its Subsidiaries or any inventor thereof, or their respective patent counsel, during the prosecution thereof are accurate and complete and comply with 37 CFR 1.56. As of the date of this Agreement, except as set forth in Section 2.13(a) of the Company Disclosure Schedule, no interference, opposition, reissue, reexamination or other proceeding of any nature (other than initial examination proceedings) is pending or, to the Company’s Knowledge, threatened in writing, in which the scope, validity, enforceability or ownership of any Company Owned Registered IP is being or has been contested or challenged.

(b) To the Company’s Knowledge, Section 2.13(b) of the Company Disclosure Schedule identifies all Encumbrances of Company IP. Except as set forth in Section 2.13(a) of the Company Disclosure Schedule, the Company or its applicable Subsidiary solely owns all right, title and interest in and to all material Company IP, free and clear of all Encumbrances other than Permitted Encumbrances and, to the Company’s Knowledge, has the right, pursuant to a Company In-bound License to use all other material Intellectual Property Rights used by the Company or its Subsidiaries in their respective businesses as currently conducted. The Company IP and the Intellectual Property Rights licensed to the Company or

its Subsidiaries pursuant to a Company In-bound License (the “Company In-Licensed IP”) are all the Intellectual Property Rights necessary to operate the business of the Company and its Subsidiaries as currently conducted and as proposed to be conducted as of the date hereof. No Company Associate owns or has any claim, right (whether or not currently exercisable) or interest to or in any Company IP, and each Company Associate involved in the creation or development of any material Company IP, pursuant to such Company Associate’s activities on behalf of the Company or its Subsidiaries, has signed a valid, enforceable written agreement containing a present assignment of all of such Company Associate’s rights in such Company IP to the Company or its Subsidiaries (without further payment being owed to any such Company Associate and without any restrictions or obligations on the Company’s or its Subsidiaries’ ownership or use thereof) and confidentiality provisions protecting the Company IP, which, to the Company’s Knowledge, has not been breached by such Company Associate. Without limiting the foregoing, the Company and its Subsidiaries have taken commercially reasonable steps to protect, maintain and enforce all Company IP and Company In-Licensed IP, including the secrecy, confidentiality and value of trade secrets and other confidential information therein, and to the Company’s Knowledge there have been no authorized disclosures of any Company IP or Company In-Licensed IP. Neither the execution and delivery of this Agreement nor the consummation of the transactions contemplated hereby will conflict with, alter or impair any of the Company’s or its Subsidiaries’ rights in or to any Company IP or Company In-Licensed IP or cause any payments of any kind to be due or payable to any Person.

(c) To the Company’s Knowledge, no funding, facilities or personnel of any Governmental Body or any university, college, research institute or other educational or academic institution has been used, in whole or in part, to create any Company IP or any Company In-Licensed IP, except for any such funding or use of facilities or personnel that does not result in such Governmental Body or institution obtaining ownership or other rights (including any “march in” rights or a right to direct the location of manufacturing of products) to such Company IP or the right to receive royalties or other consideration for the practice of such Company IP.

(d) Section 2.13(d) of the Company Disclosure Schedule sets forth each license agreement pursuant to which the Company or any of its Subsidiaries (i) is granted a license under any material Intellectual Property Right owned by any third party that is used by the Company or any of its Subsidiaries in its business as currently conducted (each a “Company In-bound License”) or (ii) grants to any third party a license, option, covenant not to sue or other right under any material Company IP or any material Company In-Licensed IP (each a “Company Out-bound License”) (provided, that, Company In-bound Licenses shall not include material transfer agreements, clinical trial agreements, services agreements, non-disclosure agreements, commercially available Software-as-a-Service offerings, off-the-shelf software licenses or generally available patent license agreements, in each case entered into in the Ordinary Course of Business on a non-exclusive basis and that do not grant any commercial rights to any products or services of the Company or its Subsidiaries; and Company Out-bound Licenses shall not include material transfer agreements, clinical trial agreements, services agreements, non-disclosure agreements, or non-exclusive outbound licenses, in each case entered into in the Ordinary Course of Business on a non-exclusive basis and that do not grant any commercial rights to any products or services of the Company or its Subsidiaries). Neither the Company nor its Subsidiaries nor, to the Company’s Knowledge, any other party to any Company In-bound License or Company Out-bound License has breached or is in breach of any of its obligations under any Company In-bound License or Company Out-bound License.

(e) To the Company’s Knowledge: (i) the operation of the businesses of the Company and its Subsidiaries as currently conducted or as proposed to be conducted as of the date hereof does not infringe or misappropriate or otherwise violate any valid and enforceable Intellectual Property Right owned by any other Person; and (ii) no other Person is infringing,

misappropriating or otherwise violating any Company IP or any Company In-Licensed IP. As of the date of this Agreement, no Legal Proceeding is pending (or, to the Company’s Knowledge, is threatened in writing) (A) against the Company or its Subsidiaries alleging that the operation of the businesses of the Company or its Subsidiaries infringes or constitutes the misappropriation or other violation of any Intellectual Property Rights of another Person or (B) by the Company or its Subsidiaries alleging that another Person has infringed, misappropriated or otherwise violated any of the Company IP or any Company In-Licensed IP. Since January 1, 2019, neither the Company nor any of its Subsidiaries has received any written notice or other written communication alleging that the operation of the business of the Company or its Subsidiaries infringes or constitutes the misappropriation or other violation of any Intellectual Property Right of another Person.

(f) None of the Company IP or, to the Company’s Knowledge, any Company In-Licensed IP is subject to any pending or outstanding injunction, directive, order, decree, settlement, judgment or other disposition of dispute that adversely and materially restricts the use, transfer, registration or licensing by the Company or its Subsidiaries of any such Company IP or Company In-Licensed IP or otherwise would reasonably be expected to adversely affect the validity, scope, use, registrability, or enforceability of any Company IP or Company In-Licensed IP.

(g) To the Company’s Knowledge, the Company, its Subsidiaries and the operation of the Company’s and its Subsidiaries’ business are in substantial compliance with all applicable Laws pertaining to data privacy and data security of any personally identifiable information and sensitive business information (collectively, “Sensitive Data”) except to the extent that such noncompliance has not and would not reasonably be expected to have a Company Material Adverse Effect. To the Company’s Knowledge, since January 1, 2019, there have been (i) no material losses or thefts of data or security breaches relating to Sensitive Data used in the business of the Company or its Subsidiaries, (ii) no violations of any security policy of the Company or its Subsidiaries regarding any such Sensitive Data, (iii) no unauthorized access or unauthorized use of any Sensitive Data used in the business of the Company or its Subsidiaries and (iv) no unintended or improper disclosure of any personally identifiable information in the possession, custody or control of the Company or its Subsidiaries, or a contractor or agent acting on behalf of the Company or its Subsidiaries, in each case of (i) through (iv), except as would not reasonably be expected to, individually or in the aggregate, have a Company Material Adverse Effect.

(h) None of the Company or its Subsidiaries is now nor has ever been a member or promoter of, or a contributor to, any industry standards body or any similar organization that would reasonably be expected to require or obligate any of the Company or its Subsidiaries to grant or offer to any other Person any license or right to any Company IP or Company In-Licensed IP.

(c) To Parent’s Knowledge, no funding, facilities or personnel of any Governmental Body or any university, college, research institute or other educational or academic institution has been used, in whole or in part, to create any Parent IP, except for any such funding or use of facilities or personnel that does not result in such Governmental Body or institution obtaining ownership or other rights (including any “march in” rights or a right to direct the location of manufacturing of products) to such Parent IP or the right to receive royalties or other consideration for the practice of such Parent IP, except as would not be reasonably expected to have, individually or in the aggregate, a material and adverse effect on Parent.

(f) None of the Parent IP or, to Parent’s Knowledge, any Parent In-Licensed IP is subject to any pending or outstanding injunction, directive, order, judgment or other disposition of dispute that adversely and materially restricts the use, transfer, registration or licensing by Parent of any such Parent IP or Parent In-Licensed IP, or otherwise would reasonably be expected to adversely affect the validity, scope, use, registrability, or enforceability of any Parent IP or Parent In-Licensed IP.

(g) To Parent’s Knowledge, Parent and the operation of Parent’s business are in substantial compliance with all applicable Laws pertaining to data privacy and data security of Sensitive Data, except to the extent that such noncompliance has not and would not reasonably be expected to have a Parent Material Adverse Effect.

4.3 Access and Investigation. Subject to the terms of the Confidentiality Agreement, which the Parties agree will continue in full force following the date of this Agreement, during the Pre-Closing Period, upon reasonable notice, Parent, on the one hand, and the Company, on the other hand, shall and shall use commercially reasonable efforts to cause such Party’s Representatives to: (a) provide the other Party and such other Party’s Representatives with reasonable access during normal business hours to such Party’s Representatives, personnel, property and assets and to all existing books, records, Tax Returns, work papers and other documents and information relating to such Party and its Subsidiaries; (b) provide the other Party and such other Party’s Representatives with such copies of the existing books, records, Tax Returns, work papers, product data, and other documents and information relating to such Party and its Subsidiaries, and with such additional financial, operating and other data and information regarding such Party and its Subsidiaries as the other Party may reasonably request; (c) permit the other Party’s officers and other employees to meet, upon reasonable notice and during normal business hours, with the chief financial officer and other officers and managers of such Party responsible for such Party’s financial statements and the internal controls of such Party to discuss such matters as the other Party may deem necessary or appropriate and; (d) make available to the other Party copies of unaudited financial statements, material operating and financial reports prepared for senior management or the board of directors of such Party, and any material notice, report or other document filed with or sent to or received from any Governmental Body in connection with the Contemplated Transactions; provided, that the Notification and Report Form and documentary attachments thereto made under the HSR Act need not be provided to the other Party; provided, further, that if a Governmental Body commences an investigation of the Contemplated Transactions under the HSR Act, any submission by a Party to such Governmental Body to respond to any requests by such Governmental Body for information or documents will be shared with the other Party, but may be restricted to the other Party’s outside counsel. Any investigation conducted by either Parent or the Company pursuant to this Section 4.3 shall be conducted in such manner as not to interfere unreasonably with the conduct of the business of the other Party.

4.4 Parent Non-Solicitation.

(a) Parent agrees that, during the Pre-Closing Period, it shall not, and shall not authorize any of its Representatives to, directly or indirectly, other than relating to communicating, discussing, negotiating or consummating the Asset Dispositions: (i) solicit, initiate or knowingly encourage, induce or facilitate the communication, making, submission or announcement of any Acquisition Proposal or Acquisition Inquiry or take any action that could reasonably be expected to lead to an Acquisition Proposal or Acquisition Inquiry; (ii) furnish any non-public information regarding Parent to any Person in connection with or in response to an Acquisition Proposal or Acquisition Inquiry; (iii) engage in discussions (other than to inform any Person of the existence of the provisions in this Section 4.4) or negotiations with any Person with respect to any Acquisition Proposal or Acquisition Inquiry; (iv) approve, endorse or recommend any Acquisition Proposal (subject to Section 5.3); (v) execute or enter into any letter of intent or any Contract contemplating or otherwise relating to any Acquisition Transaction (other than a confidentiality agreement permitted under this Section 4.4(a)); or (vi) publicly propose to do any of the foregoing; provided, however, that, notwithstanding anything contained in this Section 4.4 and subject to compliance with this Section 4.4, prior to obtaining the Required Parent Stockholder Vote, Parent may furnish non-public information regarding Parent to, and enter into discussions or negotiations with, any Person in response to an unsolicited bona fide Acquisition Proposal by such Person, which the Parent Board determines in good faith, after consultation with Parent’s outside financial advisors and outside legal counsel, constitutes, or could be reasonably likely to result in, a Superior Offer (and is not withdrawn) if: (A) neither Parent nor any of its Representatives shall have breached this Section 4.4 in any material respect, (B) the Parent Board concludes in good faith based on the advice of outside legal counsel, that the failure to take such action could be reasonably likely to be inconsistent with the fiduciary duties of the Parent Board under applicable Law; (C) Parent receives from such Person an executed confidentiality agreement containing provisions, in the aggregate, at least as favorable to Parent as those contained in the Confidentiality Agreement; and (D) substantially contemporaneously with furnishing any such non-public information to such Person, Parent furnishes such non-public information to the Company (to the extent such information has not been previously furnished by Parent to the Company). Without limiting the generality of the foregoing, Parent acknowledges and agrees that, in the event any Representative of Parent (whether or not such Representative is purporting to act on behalf of Parent) takes any action that, if taken by Parent, would constitute a breach of this Section 4.4, the taking of such action by such Representative shall be deemed to constitute a breach of this Section 4.4 by Parent for purposes of this Agreement.

(b) If Parent or any Representative of Parent receives an Acquisition Proposal or Acquisition Inquiry at any time during the Pre-Closing Period, then Parent shall promptly (and in no event later than one (1) Business Day after Parent becomes aware of such Acquisition Proposal or Acquisition Inquiry) advise the Company orally and in writing of such Acquisition Proposal or Acquisition Inquiry (including the identity of the Person making or submitting such Acquisition Proposal or Acquisition Inquiry, and the material terms thereof) and provide to the Company a copy of any written Acquisition Proposal or Acquisition Inquiry. Parent shall keep the Company reasonably informed with respect to the status and material terms of any such Acquisition Proposal or Acquisition Inquiry and any material modification or proposed material modification thereto.

(c) Parent shall immediately cease and cause to be terminated any existing discussions, negotiations and communications with any Person that relate to any Acquisition Proposal or Acquisition Inquiry (other than any Asset Disposition) that has not already been terminated as of the date of this Agreement and request the destruction or return of any non-public information of Parent provided to such Person as soon as practicable after the date of this Agreement.

4.5 Company Non-Solicitation.

(a) The Company agrees that, during the Pre-Closing Period, neither it nor any of its Subsidiaries shall, nor shall it or any of its Subsidiaries authorize any of their respective Representatives to, directly or indirectly: (i) solicit, initiate or knowingly encourage, induce or facilitate the communication, making, submission or announcement of any Acquisition Proposal or Acquisition Inquiry or take any action that could reasonably be expected to lead to an Acquisition Proposal or Acquisition Inquiry; (ii) furnish any non-public information regarding the Company or any of its Subsidiaries to any Person in connection with or in response to an Acquisition Proposal or Acquisition Inquiry; (iii) engage in discussions (other than to inform any Person of the existence of the provisions in this Section 4.5) or negotiations with any Person with respect to any Acquisition Proposal or Acquisition Inquiry; (iv) approve, endorse or recommend any Acquisition Proposal; (v) execute or enter into any letter of intent or any Contract contemplating or otherwise relating to any Acquisition Transaction; or (vi) publicly propose to do any of the foregoing. Without limiting the generality of the foregoing, the Company acknowledges and agrees that, in the event any Representative of the Company or any of its Subsidiaries (whether or not such Representative is purporting to act on behalf of the Company or any of its Subsidiaries) takes any action that, if taken by the Company, would constitute a breach of this Section 4.5, the taking of such action by such Representative shall be deemed to constitute a breach of this Section 4.5 by the Company for purposes of this Agreement.

(b) If the Company, any of its Subsidiaries or any of their respective Representatives receives an Acquisition Proposal or Acquisition Inquiry at any time during the Pre-Closing Period, then the Company shall promptly (and in no event later than one (1) Business Day after the Company becomes aware of such Acquisition Proposal or Acquisition Inquiry) advise Parent orally and in writing of such Acquisition Proposal or Acquisition Inquiry (including the identity of the Person making or submitting such Acquisition Proposal or Acquisition Inquiry, and the material terms thereof). The Company shall keep Parent reasonably informed with respect to the status and material terms of any such Acquisition Proposal or Acquisition Inquiry and any material modification or proposed material modification thereto.

(c) The Company shall immediately cease and cause to be terminated any existing discussions, negotiations and communications with any Person that relate to any Acquisition Proposal or Acquisition Inquiry that has not already been terminated as of the date of this Agreement and request the destruction or return of any non-public information of the Company or any of its Subsidiaries provided to such Person as soon as practicable after the date of this Agreement.

4.6 Notification of Certain Matters.

(a) During the Pre-Closing Period the Company shall promptly (and in no event later than one (1) Business Day after the Company becomes aware of same) notify Parent (and, if in writing, furnish copies of any relevant documents) if any of the following occurs: (i) any notice or other communication is received from any Person alleging that the Consent of such Person is or may be required in connection with any of the Contemplated Transactions; (ii) any Legal Proceeding against or involving or otherwise affecting the Company or its Subsidiaries is commenced, or, to the Company’s Knowledge, threatened against the Company or its Subsidiaries or, to the Company’s Knowledge, any director or officer of the Company or its Subsidiaries; (iii) the Company becomes aware of any inaccuracy in any representation or warranty made by it in this Agreement; (iv) any communication is received from the FDA or comparable Government Body concerning the Company business; or (v) the failure of the Company to comply with any covenant or obligation of the Company; in the case of (iii) and (v) that could reasonably be expected to make the timely satisfaction of any of the conditions set forth in Sections 6 or 7, as applicable, impossible or materially less likely. No notification given to Parent pursuant to this Section 4.6(a) shall change, limit or otherwise affect any of the representations, warranties, covenants or obligations of the Company or any of its Subsidiaries contained in this Agreement or the Company Disclosure Schedule for purposes of Sections 6 and 7, as applicable.

(b) During the Pre-Closing Period Parent shall promptly (and in no event later than one (1) Business Day after the Parent becomes aware of same) notify the Company (and, if in writing, furnish copies of any relevant documents) if any of the following occurs: (i) any notice or other communication is received from any Person alleging that the Consent of such Person is or may be required in connection with any of the Contemplated Transactions; (ii) any Legal Proceeding against or involving or otherwise affecting Parent is commenced, or, to Parent’s Knowledge, threatened against Parent or, to Parent’s Knowledge, any director or officer of Parent; (iii) Parent becomes aware of any inaccuracy in any representation or warranty made by it in this Agreement; or (iv) the failure of Parent to comply with any covenant or obligation of Parent or Merger Sub; in the case of (iii) and (iv) that could reasonably be expected to make the timely satisfaction of any of the conditions set forth in Sections 6 or 8, as applicable, impossible or materially less likely. No notification given to the Company pursuant to this Section 4.6(b) shall change, limit or otherwise affect any of the representations, warranties, covenants or obligations of Parent contained in this Agreement or the Parent Disclosure Schedule for purposes of Sections 6 and 8, as applicable.

4.7 Potentially Transferable Assets. Parent shall be entitled, but under no obligation, to separate into a new company or sell, transfer, assign or otherwise divest the Potentially Transferable Assets to a third party in one or a series of transactions prior to, concurrently with, or immediately following the Closing (each an “Asset Disposition” and collectively, the “Asset Dispositions”); provided, however, that Parent shall notify the Company at least five (5) Business Days prior to entering into any agreement with respect to any Asset Disposition and provide copies of all written agreements or documents with respect to such sale and provide the Company with an opportunity to provide comments to such documents, provided, however, that the inclusion or exclusion of such Company comments will be at the sole discretion of Parent after having considered such comments in good faith and engaging in good faith discussions with the Company regarding the same; and provided further, however, that any such Asset Disposition that would create any material post-disposition Liabilities for Parent following the Closing shall require, to the extent consistent with applicable Laws, the written consent of the Company, not to be unreasonably withheld, delayed or conditioned. Each Party acknowledges that Parent may not be successful in completing, or may determine not to proceed, with any Asset Dispositions. For clarity, if the Asset Dispositions are not completed prior to, concurrently with, or immediately following the Closing, the Potentially Transferable Assets shall be retained by Parent and the value of such Potentially Transferable Assets shall have no impact on the calculation of the Exchange Ratio.

4.8 Termination of Employees of Parent. Effective as of the Effective Time, Parent and Merger Sub shall terminate all of their respective employees other than those who will continue as employees of Parent or the Surviving Corporation following the Closing (the “Retained Employees”). At least ten (10) Business Days prior to the Closing, the Company shall deliver a list to Parent setting forth the names of any such Retained Employees.

Section 5. ADDITIONAL AGREEMENTS OF THE PARTIES

5.1 Proxy Statement.

(a) As promptly as practicable after the date of this Agreement, the Parties shall prepare, and Parent shall cause to be filed with the SEC, the Proxy Statement. Parent covenants and agrees that the Proxy Statement will not, at the time the Proxy Statement or any amendment or supplement thereto is filed with the SEC or is first mailed to Parent’s stockholders, 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 made therein, in light of the circumstances under which they were made, not misleading. The Company covenants and agrees that the information provided by or on behalf of the Company to Parent for inclusion in the Proxy Statement (including the Company Audited Financial Statements or the Company Interim Financial Statements, as the case may be) will 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 such information not misleading. Notwithstanding the foregoing, Parent makes no covenant, representation or warranty with respect to statements made in the Proxy Statement (and the letter to stockholders, notice of meeting and form of proxy included therewith), if any, based on information provided by or on behalf of the Company or any of its Representatives for inclusion therein, and the Company makes no covenant, representation or warranty with respect to statements made in the Proxy Statement (and the letter to stockholders, notice of meeting and form of proxy included therewith), if any, other than with respect to the information provided by or on behalf of the Company or any of its Representatives for inclusion therein. The Company and its legal counsel shall be given reasonable opportunity to review and comment on the Proxy Statement, including all amendments and supplements thereto, prior to the filing thereof with the SEC, and on the response to any comments of the SEC on the Proxy Statement, prior to the filing or submission thereof with or to the SEC. Parent shall use commercially reasonable efforts to cause the Proxy Statement to comply with the applicable rules and regulations promulgated by the SEC and to respond promptly to any comments of the SEC or its staff. Parent shall use commercially reasonable efforts to cause the Proxy Statement to be mailed to Parent’s stockholders as promptly as practicable after the resolution of SEC staff comments and the filing of the Definitive Proxy Statement. Each Party shall promptly furnish to the other Party all information concerning such Party and such Party’s Affiliates and such Party’s stockholders that may be required or reasonably requested in connection with any action contemplated by this Section 5.1. If Parent, Merger Sub or the Company become aware of any event or information that, pursuant to the Exchange Act, should be disclosed in an amendment or supplement to the Proxy Statement, then such Party, as the case may be, shall promptly inform the other Parties thereof and shall cooperate with such other Parties in filing such amendment or supplement with the SEC and, if appropriate, in mailing such amendment or supplement to Parent’s stockholders. No filing of, or amendment or supplement to, the Proxy Statement will be made by Parent, in each case, without the prior written consent of the Company, which shall not be unreasonably withheld, conditioned or delayed. The Company and Parent shall each use commercially reasonable efforts to cause the Proxy Statement to comply with applicable federal and state securities laws requirements.

(b) The Parties shall reasonably cooperate with each other and provide, and require their respective Representatives to provide, the other Party and its Representatives, with all true, correct and complete information regarding such Party or its Subsidiaries that is required by Law to be included in the Proxy Statement or reasonably requested by the other Party to be included in the Proxy Statement.

(c) Following the final determination of Parent Net Cash at the Anticipated Closing Date in accordance with Section 1.6 (either as a result of the mutual agreement of the parties or the determination of the Accounting Firm), Parent and the Company shall mutually agree on the form and substance of a press release setting forth the anticipated Exchange Ratio as of the Anticipated Closing Date, which the Parties shall cause to be publicly disclosed (and which Parent shall file on Form 8-K with the SEC) as early as practicable prior to the Parent Stockholders’ Meeting (and in no event shall this delay or cause the postponement of such meeting under any applicable Law).

All materials (including any amendments thereto) submitted to the stockholders of the Company in accordance with this Section 5.2(b) shall be subject to Parent’s advance review and reasonable approval.

(c) The Company covenants and agrees that the Information Statement, including any pro forma financial statements included therein (and the letter to stockholders and form of Company Stockholder Written Consent included therewith), will not, at the time that the Information Statement or any amendment or supplement thereto is first mailed, distributed or otherwise made available to its stockholders that did not execute the written consent approving the Company Stockholder Matters in accordance Section 5.2(a), at the time of receipt of the Required Company Stockholder Vote and at the Effective Time, 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 made therein, in light of the circumstances under which they were made, not misleading. Notwithstanding the foregoing, the Company makes no covenant, representation or warranty with respect to statements

made in the Information Statement (and the letter to the stockholders and form of Company Stockholder Written Consent included therewith), if any, based on information furnished in writing by Parent specifically for inclusion therein. Each of the Parties shall use commercially reasonable efforts to cause the Information Statement to comply with the applicable rules and regulations promulgated by the SEC and applicable federal and state securities laws requirements in all material respects.

(d) The Company agrees that: (i) the Company Board shall recommend that the Company’s stockholders vote to approve the Company Stockholder Matters and shall use reasonable best efforts to solicit such approval from each of the Company Signatories within the time set forth in Section 5.2(a) (the recommendation of the Company Board that the Company’s stockholders vote to adopt and approve the Company Stockholder Matters being referred to as the “Company Board Recommendation”); and (ii) the Company Board Recommendation shall not be withdrawn or modified (and the Company Board shall not publicly propose to withdraw or modify the Company Board Recommendation) in a manner adverse to Parent, and no resolution by the Company Board or any committee thereof to withdraw or modify the Company Board Recommendation in a manner adverse to Parent or to adopt, approve or recommend (or publicly propose to adopt, approve or recommend) any Acquisition Proposal shall be adopted or proposed (the actions set forth in the foregoing clause (ii), collectively, a “Company Board Adverse Recommendation Change”).

(e) The Company’s obligation to solicit the consent of its stockholders to sign the Company Stockholder Written Consent in accordance with Section 5.2(a) and Section 5.2(d) shall not be limited or otherwise affected by the commencement, disclosure, announcement or submission of any Superior Offer or other Acquisition Proposal.

5.3 Parent Stockholders’ Meeting.

(a) Promptly as reasonably practicable after the resolution of SEC staff comments and the filing of the Definitive Proxy Statement, Parent shall take all action necessary under applicable Law to call, give notice of and hold a meeting of the holders of Parent Common Stock for the purpose of seeking approval of (i) the issuance of Parent Common Stock or other securities of Parent that represent (or are convertible into) more than twenty percent (20%) of the shares of Parent Common Stock outstanding immediately prior to the Merger to the holders of Company Capital Stock, Company Options and Company Warrants in connection with the Contemplated Transactions and the change of control of Parent resulting from the Contemplated Transactions, in each case pursuant to the Nasdaq rules; (ii) in accordance with Section 14A of the Exchange Act and the applicable SEC rules issued thereunder, seeking advisory approval of a proposal to Parent’s stockholders for a non-binding, advisory vote to approve certain compensation that may become payable to Parent’s named executive officers in connection with the completion of the Merger, if applicable; and (iii) any other proposals the Parties deem necessary or desirable to consummate the Contemplated Transactions (the matters contemplated by this Section 5.3(a)(i) are collectively referred to as the “Parent Stockholder Matters,” and the matters contemplated by this Section 5.3(a)(ii) and (iii) are collectively referred to herein as, the “Other Parent Stockholder Matters,” and such meeting, the “Parent Stockholders’ Meeting”).

(b) The Parent Stockholders’ Meeting shall be held as promptly as practicable after the filing of the Definitive Proxy Statement with the SEC. Parent shall take reasonable measures to ensure that all proxies solicited in connection with the Parent Stockholders’ Meeting are solicited in compliance with all applicable Laws. Notwithstanding anything to the contrary contained herein, if on the date of the Parent Stockholders’ Meeting, or a date preceding the date on which the Parent Stockholders’ Meeting is scheduled, Parent reasonably believes that (i) it will not receive proxies sufficient to obtain the Required Parent Stockholder Vote, whether or not a quorum would be present, or (ii) it will not have sufficient shares of Parent Common Stock represented (whether in person or by proxy) to constitute a quorum necessary to conduct the business of the Parent Stockholders’ Meeting, Parent may make one or more successive postponements or adjournments of the Parent Stockholders’ Meeting as long as the date of the Parent Stockholders’ Meeting is not postponed or adjourned more than an aggregate of sixty (60) calendar days in connection with any postponements or adjournments.

(c) Parent agrees that, subject to Section 5.3(d): (i) the Parent Board shall recommend that the holders of Parent Common Stock vote to approve the Parent Stockholder Matters and the Other Parent Stockholder Matters, (ii) the Proxy Statement shall include a statement to the effect that the Parent Board recommends that Parent’s stockholders vote to approve the Parent Stockholder Matters and the Other Parent Stockholder Matters (the recommendation of the Parent Board with respect to the Parent Stockholder Matters being referred to as the “Parent Board Recommendation”); and (iii) the Parent Board Recommendation shall not be withheld, amended, withdrawn or modified (and the Parent Board shall not publicly propose to withhold, amend, withdraw or modify the Parent Board Recommendation) in a manner adverse to the Company (the actions set forth in the foregoing clause (iii), collectively, a “Parent Board Adverse Recommendation Change”).

(d) Notwithstanding anything to the contrary contained in this Agreement, if at any time prior to the approval of the Parent Stockholder Matters at the Parent Stockholders’ Meeting by the Required Parent Stockholder Vote:

(i) if Parent has received a written Acquisition Proposal (which Acquisition Proposal did not arise out of a material breach of Section 4.4) from any Person that has not been withdrawn and after consultation with outside legal counsel, the Parent Board shall have determined, in good faith, that such Acquisition Proposal is a Superior Offer, (x) the Parent Board may make a Parent Board Adverse Recommendation Change or (y) Parent may terminate this Agreement pursuant to Section 9.1(j) to enter into a Permitted Alternative Agreement with respect to such Superior Offer, if and only if all of the following apply: (A) the Parent Board determines in good faith, after consultation with Parent’s outside legal counsel, that the failure to do so would be reasonably likely to be inconsistent with the fiduciary duties of the Parent Board to Parent’s stockholders under applicable Law; (B) Parent shall have given the Company prior written notice of its intention to consider making a Parent Board Adverse Recommendation Change or terminate this Agreement pursuant to Section 9.1(j) at least three (3) Business Days prior to making any such Parent Board Adverse Recommendation Change or termination (a “Determination Notice”) (which notice shall not constitute a Parent Board Adverse Recommendation Change); and (C) (1) Parent shall have provided to the Company a summary of the material terms and conditions of the Acquisition Proposal in accordance with Section 4.4(b), (2) Parent shall have given the Company the three (3) Business Days after the Determination Notice to propose revisions to the terms of this Agreement or make another proposal and shall have made its Representatives reasonably available to negotiate in good faith with the Company (to the extent the Company desires to negotiate) with respect to such proposed revisions or other proposal, if any, and (3) after considering the results of any such negotiations and giving effect to the proposals made by the Company, if any, after consultation with outside legal counsel, the Parent Board shall have determined, in good faith, that such Acquisition Proposal is a Superior Offer and that the failure to make the Parent Board Adverse Recommendation Change or terminate this Agreement pursuant to Section 9.1(j) would be reasonably likely to be inconsistent with the fiduciary duties of the Parent Board to Parent’s stockholders under applicable Law. For the avoidance of doubt, the provisions of this Section 5.3(d)(i) shall also apply to any material change to the facts and circumstances relating to such Acquisition Proposal and require a new Determination Notice, except that the references to three (3) Business Days shall be deemed to be two (2) Business Days.

(ii) other than in connection with an Acquisition Proposal, the Parent Board may make a Parent Board Adverse Recommendation Change in response to a Parent Change in Circumstance, if and only if: (A) the Parent Board determines in good faith, after consultation with Parent’s outside legal counsel, that the failure to do so would be reasonably likely to be inconsistent with the fiduciary duties of the Parent Board to Parent’s stockholders under applicable Law; (B) Parent shall have given the Company a Determination Notice at least three (3) Business Days prior to making any such Parent Board Adverse Recommendation Change; and (C) (1) Parent shall have specified the Parent Change in Circumstance in reasonable detail, (2) Parent shall have given the Company the three (3) Business Days after the Determination Notice to propose revisions to the terms of this Agreement or make another proposal, and shall have made its Representatives reasonably available to negotiate in good faith with the Company (to the extent the Company desires to do so) with respect to such proposed revisions or other proposal, if any, and (3) after considering the results of any such negotiations and giving effect to the proposals made by the Company, if any, after consultation with outside legal counsel, the Parent Board shall have determined, in good faith, that the failure to make the Parent Board Adverse Recommendation Change in response to such Parent Change in Circumstance would be reasonably likely to be inconsistent with the fiduciary duties of the Parent Board to Parent’s stockholders under applicable Law. For the avoidance of doubt, the provisions of this Section 5.3(d)(ii) shall also apply to any material change to the facts and circumstances relating to such Parent Change in Circumstance and require a new Determination Notice, except that the references to three (3) Business Days shall be deemed to be two (2) Business Days.

(e) Nothing contained in this Agreement shall prohibit Parent or the Parent Board from (i) complying with Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act, (ii) issuing a “stop, look and listen” communication or similar communication of the type contemplated by Section 14d-9(f) under the Exchange Act or (iii) otherwise making any disclosure to Parent’s stockholders; provided however, that in the case of the foregoing clause (iii) the Parent Board determines in good faith, after consultation with its outside legal counsel, that failure to make such disclosure could be reasonably likely to be inconsistent with applicable Law, including its fiduciary duties under applicable Law.

5.4 Regulatory Approvals.

(a) Each Party shall, and shall cause its ultimate parent entity (as such term is defined in the HSR Act) to, use reasonable best efforts to file or otherwise submit, as soon as practicable after the date of this Agreement, all applications, notices, reports, filings and other documents reasonably required to be filed by such Party or its ultimate parent entity with or otherwise submitted by such Party or its ultimate parent entity to any Governmental Body with respect to the Contemplated Transactions, and shall file no later than ten (10) Business Days thereafter the Notification and Report Forms required by the HSR Act. Each Party shall (i) promptly supply the other with any information which may be required in order to effectuate such filings, (ii) submit promptly any additional information which may be reasonably requested by any such Governmental Body, and (iii) coordinate with the other Party in making any such filings or information submissions pursuant to and in connection with the foregoing that may be necessary, proper, or advisable in order to consummate and make effective the Contemplated Transactions.

(b) Without limiting the generality of anything contained in this Section 5.4, in connection with its efforts to obtain all requisite approvals and authorizations, and the expiration or termination of all applicable waiting periods for the Contemplated Transactions under any Antitrust Law, each Party hereto shall use its reasonable best efforts to (i) cooperate with the other with respect to any investigation or other inquiry; (ii) promptly provide to the other a copy of all communications received by such Party from, or given by such Party

to, any Governmental Body, in each case regarding the Contemplated Transactions; and (iii) to the extent not prohibited under applicable Antitrust Law, permit the other to review in advance any communication given by it to any Governmental Body concerning the Contemplated Transactions, consider in good faith the views of the other in connection with any proposed written communications by such Party to any Governmental Body concerning the Contemplated Transactions, and consult with each other in advance of any meeting or telephone or video conference with, any Governmental Body, and give the other or its outside counsel the opportunity to attend and participate in such meetings and conferences unless prohibited by the applicable Governmental Body; provided, that materials required to be provided pursuant to this Section 5.4(b) may be restricted to outside counsel and redacted to (A) remove references concerning the valuation of either Party, (B) comply with contractual arrangements, and (C) preserve attorney-client privilege. Neither Party shall commit to or agree with any Governmental Body to stay, toll or extend any applicable waiting period under applicable Antitrust Law, or pull and refile under the HSR Act, without the prior written consent of the other. Parent and the Company shall each pay one-half of the filing fee under the HSR Act relating to the HSR filing required for the Merger; provided, however, that each Party shall bear its own legal fees.

(c) Except as required by this Agreement, prior to Closing, neither the Company nor Parent shall, and shall cause its Affiliates not to, acquire or agree to acquire by merging or consolidating with, or by purchasing a substantial portion of the assets of or equity in, or by any other manner, any Person or portion thereof, or otherwise acquire or agree to acquire any assets, if the entering into of an agreement relating to or the consummation of such acquisition, merger or consolidation would reasonably be expected to (i) impose any delay in the obtaining of, or significantly increase the risk of not obtaining, any authorizations, consents, orders, declarations or approvals of any Governmental Body necessary to consummate the Contemplated Transactions or the expiration or termination of any applicable waiting period, or (ii) increase the risk of any Governmental Body entering an order prohibiting the consummation of the Contemplated Transactions.

5.5 Company Options and Company Warrants.

(a) At the Effective Time, each Company Option that is outstanding and unexercised immediately prior to the Effective Time under the Company Plan, whether or not vested, shall be converted into and become an option to purchase Parent Common Stock, and Parent shall assume the Company Plan and each such Company Option in accordance with the terms (as in effect as of the date of this Agreement) of the Company Plan and the terms of the stock option agreement by which such Company Option is evidenced (but with changes to such documents as Parent and the Company mutually agree are appropriate to reflect the substitution of the Company Options by Parent to purchase shares of Parent Common Stock). All rights with respect to Company Common Stock under Company Options assumed by Parent shall thereupon be converted into rights with respect to Parent Common Stock. Accordingly, from and after the Effective Time: (i) each Company Option assumed by Parent may be exercised solely for shares of Parent Common Stock; (ii) the number of shares of Parent Common Stock subject to each Company Option assumed by Parent shall be determined by multiplying (A) the number of shares of Company Common Stock that were subject to such Company Option, as in effect immediately prior to the Effective Time, by (B) the Exchange Ratio, and rounding the resulting number down to the nearest whole number of shares of Parent Common Stock; (iii) the per share exercise price for the Parent Common Stock issuable upon exercise of each Company Option assumed by Parent shall be determined by dividing (A) the per share exercise price of Company Common Stock subject to such Company Option, as in effect immediately prior to the Effective Time, by (B) the Exchange Ratio, and rounding the resulting exercise price up to the nearest whole cent; and (iv) any restriction on the exercise of any Company Option assumed by Parent shall continue

in full force and effect and the term, exercisability, vesting schedule and other provisions of such Company Option shall otherwise remain unchanged; provided, however, that: (A) Parent may amend the terms of the Company Options and the Company Plan to reflect Parent’s substitution of the Company Options with options to purchase Parent Common Stock (such as by making any change in control or similar definition relate to Parent and having any provision that provides for the adjustment of Company Options upon the occurrence of certain corporate events relate to corporate events that relate to Parent and/or Parent Common Stock); and (B) the Parent Board or a committee thereof shall succeed to the authority and responsibility of the Company Board or any committee thereof with respect to each Company Option assumed by Parent. Each Company Option so assumed by Parent is intended to qualify following the Effective Time as an incentive stock option as defined in Section 422 of the Code to the extent permitted under Section 422 of the Code and to the extent such Company Option qualified as an incentive stock option prior to the Effective Time, and, further, the assumption of such Company Option pursuant to this Section 5.5(a) shall be effected in a manner that satisfies the requirements of Sections 409A and 424(a) of the Code and the Treasury Regulations promulgated thereunder, and this Section 5.5(a) will be construed consistent with this intent.

(b) Parent shall file with the SEC, promptly, but no later than thirty (30) calendar days after the Effective Time, a registration statement on Form S-8 (or any successor form), if available for use by Parent, relating to the shares of Parent Common Stock that are either (i) issuable with respect to Company Options assumed by Parent in accordance with Section 5.5(a) or (ii) reserved for future grants under the Company Plan.

(c) At the Effective Time, each Company Warrant that is outstanding and unexercised as of immediately prior to the Effective Time, if any, and after giving effect to the Preferred Stock Conversion, shall be converted into and become a warrant to purchase Parent Common Stock and Parent shall assume each such Company Warrant in accordance with its terms. All rights with respect to Company Capital Stock under Company Warrants assumed by Parent shall thereupon be converted into rights with respect to Parent Common Stock. Accordingly, from and after the Effective Time: (i) each Company Warrant assumed by Parent may be exercised solely for shares of Parent Common Stock; (ii) the number of shares of Parent Common Stock subject to each Company Warrant assumed by Parent shall be determined by multiplying (A) the number of shares of Company Common Stock, or the number of shares of Company Preferred Stock issuable upon exercise of the Company Warrant, as applicable, that were subject to such Company Warrant immediately prior to the Effective Time by (B) the Exchange Ratio and rounding the resulting number up to the nearest whole number of shares of Parent Common Stock; (iii) the per share exercise price for the Parent Common Stock issuable upon exercise of each Company Warrant assumed by Parent shall be determined by dividing the per share exercise price of Company Capital Stock subject to such Company Warrant, as in effect immediately prior to the Effective Time, by the Exchange Ratio and rounding the resulting exercise price up to the nearest whole cent; and (iv) any restriction on any Company Warrant assumed by Parent shall continue in full force and effect and the term and other provisions of such Company Warrant shall otherwise remain unchanged.

(d) Prior to the Effective Time, the Company shall take all actions that may be necessary (under the Company Plan, the Company Warrants and otherwise) to effectuate the provisions of this Section 5.5 and to ensure that, from and after the Effective Time, holders of Company Options and Company Warrants have no rights with respect thereto other than those specifically provided in this Section 5.5.

5.6 Employee Benefits.

(a) For purposes of vesting, eligibility to participate, and level of benefits under the benefit plans, programs, contracts or arrangements of Parent or any of its Subsidiaries (including, following the Effective Time, the Surviving Corporation) providing benefits to any Continuing Employee after the Closing (the “Post-Closing Plans”), each employee who continues to be employed by Parent, the Surviving Corporation or any of their respective Subsidiaries immediately following the Closing (“Continuing Employees”) shall be credited with his or her years of service with Parent, the Company or any of their respective Subsidiaries, as applicable, and their respective predecessors; provided, however, that the foregoing shall not apply to the extent that its application would result in a duplication of benefits. In addition, and without limiting the generality of the foregoing, for purposes of each Post-Closing Plan providing medical, dental, pharmaceutical and/or vision benefits to a Continuing Employee, the Surviving Corporation shall cause all pre-existing condition exclusions and actively-at-work requirements of such Post-Closing Plan to be waived for such Continuing Employee and his or her covered dependents to the extent such conditions would have been waived or satisfied under the employee benefit plan whose coverage is being replaced under the Post-Closing Plan, and the Surviving Corporation shall use commercially reasonable efforts to cause any eligible expenses incurred by a Continuing Employee and his or her covered dependents during the portion of such plan year in which coverage is replaced with coverage under a Post-Closing Plan to be taken into account under such Post-Closing Plan with respect to the plan year in which participation in such Post-Closing Plan begins 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 such plan year as if such amounts had been paid in accordance with such Post-Closing Plan.

(b) Parent shall provide, or shall cause the Surviving Corporation or any of their respective Subsidiaries to provide, severance payments and benefits to each Continuing Employee who was an employee of Parent or any of its Subsidiaries prior to the Closing that are no less favorable than the severance payments and benefits listed on Section 5.6(b) of the Parent Disclosure Schedule.

(c) The provisions of this Section 5.6 are for the sole benefit of Parent and the Company and no provision of this Agreement shall (i) create any third-party beneficiary or other rights in any Person, including rights in respect of any benefits that may be provided, directly or indirectly, under any Company Benefit Plan, Parent Benefit Plan or Post-Closing Plan or rights to continued employment or service with the Company or Parent (or any Subsidiary thereof), (ii) be construed as an amendment, waiver or creation of or limitation on the ability to terminate any Company Benefit Plan, Parent Benefit Plan or Post-Closing Plan, or (iii) limit the ability of Parent to terminate the employment of any Continuing Employee.

(d) During the Pre-Closing Period, Parent shall use commercially reasonable efforts to make the Parent Associates set forth on Section 5.6(d) of the Parent Disclosure Schedule available to the Company at the Company’s reasonable request, for purposes of informational interviews and discussions regarding their employment following the Closing.

5.7 Indemnification of Officers and Directors.

(a) From the Effective Time through the sixth (6th) anniversary of the date on which the Effective Time occurs, each of Parent and the Surviving Corporation, jointly and severally, shall indemnify and hold harmless each person who is now, or has been at any time prior to the date hereof, or who becomes prior to the Effective Time, a director, officer, fiduciary or agent of Parent or the Company and their respective Subsidiaries, respectively (the “D&O Indemnified Parties”), against all claims, losses, liabilities, damages, judgments, fines and reasonable fees, costs and expenses, including attorneys’ fees and disbursements, incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to the fact that the D&O

Indemnified Party is or was a director, officer, fiduciary or agent of Parent or of the Company, whether asserted or claimed prior to, at or after the Effective Time, in each case, to the fullest extent permitted under applicable Law. Each D&O Indemnified Party will be entitled to advancement of expenses incurred in the defense of any such claim, action, suit, proceeding or investigation from each of Parent and the Surviving Corporation, jointly and severally, upon receipt by Parent or the Surviving Corporation from the D&O Indemnified Party of a request therefor; provided that any such person to whom expenses are advanced provides an undertaking to Parent, to the extent then required by the DGCL, to repay such advances if it is ultimately determined that such person is not entitled to indemnification.

(b) The provisions of the Organizational Documents of Parent with respect to indemnification, advancement of expenses and exculpation of present and former directors and officers of Parent that are set forth in the Organizational Documents of Parent as of the date of this Agreement shall not be amended, modified or repealed for a period of six (6) years from the Effective Time in a manner that would adversely affect the rights thereunder of individuals who, at or prior to the Effective Time, were officers or directors of Parent. The Organizational Documents of the Surviving Corporation shall contain, and Parent shall cause the Organizational Documents of the Surviving Corporation to so contain, provisions no less favorable with respect to indemnification, advancement of expenses and exculpation of present and former directors and officers as those set forth in the Organizational Documents of Parent as of the date of this Agreement.

(c) From and after the Effective Time, (i) the Surviving Corporation shall fulfill and honor in all respects the obligations of the Company to its D&O Indemnified Parties as of immediately prior to the Closing pursuant to any indemnification provisions under the Company’s Organizational Documents and pursuant to any indemnification agreements between the Company and such D&O Indemnified Parties, with respect to claims arising out of matters occurring at or prior to the Effective Time and (ii) Parent shall fulfill and honor in all respects the obligations of Parent to its D&O Indemnified Parties as of immediately prior to the Closing pursuant to any indemnification provisions under Parent’s Organizational Documents and pursuant to any indemnification agreements between Parent and such D&O Indemnified Parties, with respect to claims arising out of matters occurring at or prior to the Effective Time.

(d) From and after the Effective Time, Parent shall maintain directors’ and officers’ liability insurance policies, with an effective date as of the Closing Date, on commercially available terms and conditions and with coverage limits customary for U.S. public companies similarly situated to Parent. In addition, Parent shall purchase, prior to the Effective Time, a six (6)-year prepaid “tail policy” (the “D&O Tail Policy”) for the non-cancellable extension of the directors’ and officers’ liability coverage of Parent’s existing directors’ and officers’ insurance policies for a claims reporting or discovery period of at least six (6) years from and after the Effective Time with respect to any claim related to any period of time at or prior to the Effective Time. During the term of the D&O Tail Policy, Parent shall not take any action following the Effective Time to cause the D&O Tail Policy to be cancelled or any provision therein to be amended or waived in any manner that would adversely affect in any material respect the rights of their former and current officers and directors.

(e) From and after the Effective Time, Parent shall pay all expenses, including reasonable attorneys’ fees, that are incurred by the persons referred to in this Section 5.7 in connection with their successful enforcement of the rights provided to such persons in this Section 5.7.

(f) All rights to exculpation, indemnification and advancement of expenses for acts or omissions occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Closing, now existing in favor of the current or former directors, officers or employees, as the case may be, of Parent or the Company as provided in their respective

Organizational Documents or in any agreement shall survive the Merger and shall continue in full force and effect. The provisions of this Section 5.7 are intended to be in addition to the rights otherwise available to the current and former officers and directors of Parent and the Company by Law, charter, statute, bylaw or agreement, and shall operate for the benefit of, and shall be enforceable by, each of the D&O Indemnified Parties, their heirs and their representatives.

(g) From and after the Effective Time, in the event Parent or the Surviving Corporation 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 all or substantially all 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 Parent or the Surviving Corporation, as the case may be, shall succeed to the obligations set forth in this Section 5.7. Parent shall cause the Surviving Corporation to perform all of the obligations of the Surviving Corporation under this Section 5.7. The obligations set forth in this Section 5.7 shall not be terminated, amended or otherwise modified in any manner that adversely affects any D&O Indemnified Party, or any person who is a beneficiary under the policies referred to in this Section 5.7 and their heirs and representatives, without the prior written consent of such affected D&O Indemnified Party or other person

5.8 Additional Agreements. The Parties shall (a) use commercially reasonable efforts to cause to be taken all actions necessary to consummate the Contemplated Transactions and (b) reasonably cooperate with the other Parties and provide the other Parties with such assistance as may be reasonably requested for the purpose of facilitating the performance by each Party of its respective obligations under this Agreement and to enable the Surviving Corporation to continue to meet its obligations under this Agreement following the Closing. Without limiting the generality of the foregoing, each Party to this Agreement: (i) shall make all filings and other submissions (if any) and give all notices (if any) required to be made and given by such Party in connection with the Contemplated Transactions; (ii) shall use reasonable best efforts to obtain each Consent (if any) reasonably required to be obtained (pursuant to any applicable Law or Contract, or otherwise) by such Party in connection with the Contemplated Transactions or for such Contract (with respect to Contracts set forth in Section 5.8 of the Company Disclosure Schedule or Section 5.8 of the Parent Disclosure Schedule, as applicable) to remain in full force and effect; (iii) shall use commercially reasonable efforts to lift any injunction prohibiting, or any other legal bar to, the Contemplated Transactions; and (iv) shall use commercially reasonable efforts to satisfy the conditions precedent to the consummation of this Agreement.

5.9 Public Announcement. The initial press release relating to this Agreement shall be a joint press release issued by the Company and Parent and thereafter Parent and the Company shall consult with each other before issuing any further press release(s) or otherwise making any public statement or making any announcement to Parent Associates or Company Associates (to the extent not previously issued or made in accordance with this Agreement) with respect to the Contemplated Transactions and shall not issue any such press release, public statement or announcement to Parent Associates or Company Associates without the other Party’s written consent (which shall not be unreasonably withheld, conditioned or delayed). Notwithstanding the foregoing: (a) each Party may, without such consultation or consent, make any public statement in response to questions from the press, analysts, investors or those attending industry conferences, make internal announcements to employees and make disclosures in Parent SEC Documents, so long as such statements are consistent with public disclosures or public statements made jointly by the Parties (or individually, if approved by the other Party); (b) a Party may, without the prior consent of the other Party hereto but subject to giving advance notice to the other Party, issue any such press release or make any such public announcement or statement as may be required by any applicable Law; and (c) Parent need not consult with the Company in connection with such portion of any press release, public statement or filing to be issued or made pursuant to Section 5.3(e) or with respect to any Acquisition Proposal or Parent Board Adverse Recommendation Change.

5.10 Listing. Parent shall use its commercially reasonable efforts, (a) to maintain its existing listing on Nasdaq until the Effective Time and to obtain approval of the listing of the combined corporation on Nasdaq; (b) to the extent required by the rules and regulations of Nasdaq, to prepare and submit to Nasdaq a notification form for the listing of the shares of Parent Common Stock to be issued in connection with the Contemplated Transactions, and to cause such shares to be approved for listing (subject to official notice of issuance); and (c) to the extent required by Nasdaq Marketplace Rule 5110, to file an initial listing application for the Parent Common Stock on Nasdaq (the “Nasdaq Listing Application”) and to cause such Nasdaq Listing Application to be conditionally approved prior to the Effective Time. Each Party will reasonably promptly inform the other Party of all verbal or written communications between Nasdaq and such Party or its representatives. The Parties will use commercially reasonable efforts to coordinate with respect to compliance with Nasdaq rules and regulations. The Company agrees to pay all Nasdaq fees associated with the Nasdaq Listing Application. The Company will cooperate with Parent as reasonably requested by Parent with respect to the Nasdaq Listing Application and promptly furnish to Parent all information concerning the Company and its stockholders that may be required or reasonably requested in connection with any action contemplated by this Section 5.10.

5.11 Tax Matters.

(a) For United States federal income Tax purposes, (i) the Parties intend that the Merger qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and (ii) this Agreement is intended to be, and is hereby adopted as, a “plan of reorganization” for purposes of Sections 354 and 361 of the Code and Treasury Regulations Sections 1.368-2(g) and 1.368-3(a), to which Parent, Merger Sub and the Company are parties under Section 368(b) of the Code.

(b) The Parties shall use their respective reasonable best efforts to cause the Merger to qualify, and will not knowingly take any action (or knowingly fail to take any action) or knowingly cause any action to be taken (or omission to occur) which action (or omission) would reasonably be expected to prevent the Merger from qualifying, for the Intended Tax Treatment. Neither Party shall take any Tax reporting position inconsistent with the Intended Tax Treatment for United States federal income Tax purposes unless otherwise required by a change in applicable Law after the date of this Agreement or a “determination” within the meaning of Section 1313(a) of the Code. Notwithstanding the foregoing, none of Parent, Merger Sub, or the Company makes any representations or warranties to any securityholder of Parent or the Company regarding the Tax treatment of the Merger, or any of the Tax consequences to any securityholder of Parent or the Company of this Agreement, the Merger or any of the Contemplated Transactions.

5.12 Legends. Parent shall be entitled to place appropriate legends on the book entries and/or certificates evidencing any shares of Parent Common Stock to be received in the Merger by the equity holders of the Company who may be considered “affiliates” of Parent for purposes of Rules 144 and 145 promulgated under the Securities Act reflecting the restrictions set forth in Rules 144 and 145 and to issue appropriate stop transfer instructions to the transfer agent for Parent Common Stock.

5.13 Directors and Officers. The Parties shall use reasonable best efforts and take all necessary action so that immediately after the Effective Time, (a) the Parent Board is comprised of ten (10) members, with three (3) such members designated by Parent and seven (7) such members designated by the Company, (b) the Persons listed in Exhibit E under the heading “Officers” are elected or appointed, as applicable, to the positions of officers of Parent, as set forth therein, to serve in such positions effective as of the Effective Time until successors are duly appointed and qualified in accordance with applicable Law. If any Person listed in Exhibit E is unable or unwilling to serve as an officer of Parent, as set forth therein, as of the Effective Time, the Parties shall mutually agree upon a successor. The Persons listed in Exhibit E under the heading “Board Designees – Parent” shall be Parent’s designees pursuant to clause (a) of this Section 5.13 (which list may be changed by Parent at any time prior to the Closing by written notice to the Company to include different board designees who

are reasonably acceptable to the Company) (the “Parent Designees”). The Persons listed in Exhibit E under the heading “Board Designees – Company” shall be the Company’s designees pursuant to clause (a) of this Section 5.13 (which list may be changed by the Company at any time prior to the Closing by written notice to Parent to include different board designees who are reasonably acceptable to Parent).
