AGREEMENT:

NOW, THEREFORE, in consideration of the foregoing and the representations, warranties and covenants herein contained, and for other good and valuable consideration, the receipt, adequacy and sufficiency of which are hereby acknowledged, the Parties, intending to be legally bound, hereby agree as follows:

ARTICLE 1

THE ACQUISITION

1.1The Acquisition. Upon the terms and subject to the conditions of this Agreement, at the Closing, Sellers shall (on a several and not joint basis) sell, transfer and convey to Company, and Company shall purchase from Sellers, all of the F-Star Shares free from all Encumbrances. The F-Star Shares shall be sold with all rights attaching to them at Closing or subsequently, including the rights to receive all dividends and other distributions declared, made or paid on F-Star Shares after Closing. Company shall not be obliged to complete the purchase and sale of the F-Star Shares unless the purchase and sale of all the F-Star Shares is completed simultaneously. Each Seller hereby waives any rights of preemption or other restrictions on transfer in respect of the F-Star Shares, whether conferred by the Articles of Association, the Shareholders’ Agreement or otherwise, in respect of the transfers of the F-Star Shares

contemplated by this Agreement and approves such transfer for the purposes of the Shareholders’ Agreement, Articles of Association or otherwise. The purchase and sale of the F-Star Shares pursuant to this Agreement is referred to herein as the “Acquisition.”

1.2Closing. Unless this Agreement has been terminated and the Contemplated Transactions have been abandoned pursuant to Section 8.1, and subject to the satisfaction or waiver of the conditions set forth in Article 7, the consummation of the Acquisition (the “Closing”) will take place at the offices of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., ▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇▇▇, as soon as possible (but in any event no later than two (2) Business Days) after satisfaction or waiver of the conditions set forth in Article 7 (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of each such condition), or at such other time, date and place as F-Star and Company may mutually agree in writing. The date on which the Closing actually takes place is referred to as the “Closing Date.”

1.3Company Name Change. Unless otherwise determined by F-Star, Company and F-Star will take any and all action necessary to change Company’s name to “F-Star Therapeutics, Inc.” effective immediately following the Closing.

1.4F-Star Securities.

(a)F-Star Shares. Each F-Star Share in issue immediately prior to the Closing will be sold to Company by the Seller that owns such F-Star Share in consideration for such number of duly authorized, validly issued, fully paid and non-assessable shares of Company Common Stock as is equal to the Exchange Ratio, rounded to the nearest whole share of Company Common Stock (after aggregating all fractional shares of Company Common Stock issuable to such Seller) (the “Acquisition Consideration”).

(b)F-Star Options and F-Star RSUs. Each F-Star Option that is outstanding and unexercised immediately prior to the Closing and each F-Star RSU will be treated in accordance with Section 6.15.

(c)Adjustments to Exchange Ratio. The Exchange Ratio will be calculated in the manner described in the definition of “Exchange Ratio” on Exhibit A hereto and will be appropriately adjusted to reflect fully the effect of any stock split, reverse split (including the Company Reverse Stock Split to the extent such split has not previously been taken into account in calculating the Exchange Ratio), stock dividend (including any dividend or distribution of securities convertible into shares in the F-Star Share Capital or Company Common Stock), reorganization, recapitalization or other like change with respect to shares in the F-Star Share Capital or Company Common Stock occurring after the date hereof and prior to the Closing.

(d)No Fractional Shares. No fractional shares of Company Common Stock will be issued in connection with the Acquisition, and no certificates or scrip for any such fractional shares of Company Common Stock will be issued. Sellers will not be entitled to any voting rights, rights to receive any dividends or distributions or other rights as a stockholder of Company with respect to any such fractional shares of Company Common Stock that would have otherwise been issued to such Seller.

(e)Share Conversion. Conditional upon the Company Stockholder Approval, each Seller hereby irrevocably agrees to the Share Conversion upon the terms described herein, which shall be deemed to occur immediately prior to the Closing.

1.5Calculation of Net Cash.

(a)Not less than five (5) calendar days prior to the anticipated date for Closing (the “Anticipated Closing Date”), Company will deliver to F-Star a schedule (the “Net Cash Schedule”) setting forth, in reasonable detail, Company’s good faith, estimated calculation of Net Cash (the “Net Cash Calculation” and the date of delivery of such schedule, the “Delivery Date”) as of the close of business on the last Business Day prior to the Anticipated Closing Date (the “Cash Determination Time”) prepared and certified by Company’s Chief Financial Officer (or if there is no Chief Financial Officer, Company’s principal accounting officer). Company shall make available to F-Star, as requested by F-Star, the work papers and back-up materials used in or reasonably relevant to the preparation of the Net Cash Schedule and, if reasonably requested by F-Star, Company’s accountants and counsel at reasonable times and upon reasonable advance notice.

(b)Within three (3) calendar days after the Delivery Date (the last day of such period, the “Response Date”), F-Star shall have the right to dispute any part of the Net Cash Calculation by delivering a written notice to that effect to Company (a “Dispute Notice”). Any Dispute Notice shall identify in reasonable detail and to the extent known the nature and amounts of any proposed revisions to the Net Cash Calculation F-Star reasonably believes to be necessary and appropriate.

(c)If, on or prior to the Response Date, F-Star notifies Company in writing that it has no objections to the Net Cash Calculation or, if F-Star fails to deliver a Dispute Notice as provided in Section 1.5(b) by 11:59 p.m. Eastern Time on the Response Date, 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 the Net Cash at the Cash Determination Time for all purposes under this Agreement.

(d)If F-Star timely delivers a Dispute Notice to Company, then Representatives of Company and F-Star shall promptly meet and attempt in good faith to resolve any disputes between them regarding the Net Cash Calculation and negotiate an agreed-upon determination of Net Cash, which agreed upon Net Cash amount shall be deemed to have been finally determined for purposes of this Agreement and to represent the Net Cash at the Cash Determination Time for all purposes under this Agreement.

(e)If Representatives of Company and F-Star are unable to negotiate an agreed-upon determination of Net Cash as of the Cash Determination Time pursuant to Section 1.5(d) within three (3) calendar days after delivery of the Dispute Notice (or such other period as Company and F-Star may mutually agree upon), then any remaining matters in dispute regarding the calculation of Net Cash shall be referred to ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP (the “Accounting Firm”). At the Accounting Firm’s request, (i) Company shall promptly make available or deliver to the Accounting Firm such work papers and back-up materials used by Company in preparing the Net Cash Schedule as the Accounting Firm reasonably requests, and (ii) F-Star

shall promptly make available or deliver to the Accounting Firm such work papers and back-up materials used by F‑Star in disputing Company’s Net Cash Calculation as the Accounting Firm reasonably requests, and Company and F-Star shall use commercially reasonable efforts to cause the Accounting Firm to resolve all remaining matters in dispute within five (5) Business Days of accepting its selection. Company and F-Star shall be afforded the opportunity to present to the Accounting Firm any material related to all matters in dispute and to discuss the basis for such dispute with the Accounting Firm; provided, however, that no such presentation or discussion shall occur without the presence of a Representative of each of Company and F-Star. The determination of the Accounting Firm shall be limited to the matters in dispute submitted to the Accounting Firm for final determination. The Accounting Firm shall act as an expert and not as an arbitrator and shall be instructed to resolve only such matters relating to the calculation of Net Cash as are then in dispute. The resolution of the matters in dispute made by the Accounting Firm and the resulting calculation of the amount of Net Cash giving effect to such resolution shall be made in writing and delivered to each of Company and F-Star, shall be final and binding on Company and F-Star and shall be deemed to have been finally determined for purposes of this Agreement and to represent the Net Cash at the Cash Determination Time for all purposes under this Agreement. The Parties shall delay the Closing until the resolution of the matters described in this Section 1.5(e). The fees and expenses of the Accounting Firm shall be allocated between Company and F-Star in the same proportion that the amount of the matters in dispute that were unsuccessfully disputed by such Party (as finally determined by the Accounting Firm) bears to the total amount of all disputed matters resolved by the Accounting Firm. If this Section 1.5(e) applies as to the determination of the Net Cash at the Cash Determination Time described in Section 1.5(a), upon resolution of the matters in dispute in accordance with this Section 1.5(e), the Parties shall not be required to determine Net Cash again even though the Closing Date may occur later than the Anticipated Closing Date, except that either Company or F-Star may request a redetermination of Net Cash (using the principles established by the Accounting Firm in resolving the matters in dispute pursuant to this Section 1.5(e)) if the Closing Date is more than seven (7) calendar days after the Anticipated Closing Date.

(f)In the event that Net Cash, as finally determined pursuant to this Section 1.5, exceeds the Net Cash Limit, Company shall declare and pay the Permitted Dividend to holders of Company Common Stock of record as of immediately prior to the Closing.

1.6F-Star Loan Notes. Capitalized terms used in this Section 1.6 and not otherwise defined have the respective meanings ascribed in the 2019 Loan Note Instrument.

(a)F-Star and each of the 2019 Loan Note Holders (representing a Noteholder Majority) by their execution and delivery of this Agreement hereby irrevocably agree and acknowledge that this Agreement constitutes notice in writing that the F-Star Pre-Closing Financing will constitute a Relevant Fundraising for the purposes of the 2019 Loan Note Instrument notwithstanding that the aggregate proceeds of the F-Star Pre Closing Financing together with the nominal value of the 2019 Loan Notes which are converting are less than $50,000,000 in the aggregate.

(b)On the Closing Date immediately subsequent to the Share Conversion and simultaneously with the issuance of the F-Star Ordinary Shares in the F-Star Pre-Closing Financing, the 2019 Loan Notes shall automatically convert into fully paid F-Star Ordinary

Shares (being, the class of Senior Shares as such term is defined in the 2019 Loan Note Instrument) in accordance with the terms of Part 2 of Schedule 2 to the 2019 Loan Note Instrument and the terms described below (the “2019 Loan Note Conversion”). The 2019 Loan Note Holders, each by their execution and delivery of this Agreement as a Seller, hereby irrevocably agree and acknowledge as follows with respect to the 2019 Loan Note Conversion:

(i)the applicable Conversion Price (as such term is used in Part 2 of Schedule 2 to the 2019 Loan Note Instrument) shall be an amount equal to eighty percent (80%) of the price paid per F-Star Ordinary Share by participants in the F-Star Pre‑Closing Financing and neither such price nor the number or nominal value of the F-Star Ordinary Shares issued pursuant to the 2019 Loan Note Conversion shall be subject to any adjustment under clause 2.6 of Part 2 of Schedule 2 to the 2019 Loan Note Instrument;

(ii)this Agreement shall constitute due prior written notice by F-Star of a Conversion Event (as such term is used in Part 2 of the Schedule 2 to the 2019 Loan Instrument) in accordance with the terms of paragraph 1.3, of Part 2 of Schedule 2 to the 2019 Loan Note Instrument;

(iii)each 2019 Loan Note Holder undertakes to F-Star that it will, prior to the 2019 Loan Note Conversion, deliver to F-Star its original certificate in respect of the 2019 Loan Notes it holds (or an indemnity in a form acceptable to F-Star and Company in respect thereof);

(iv)that effective upon the 2019 Loan Note Conversion, neither F-Star nor Company shall have any further obligations to such 2019 Loan Note Holder (other than the issuance by F-Star of F-Star Ordinary Shares on the terms contemplated herein); and

(v)for the purposes of the 2019 Loan Note Instrument, each 2019 Loan Note Holder (representing, for such purposes, a Noteholder Majority) hereby approves the form and adoption by F-Star of the Closing Articles of Association.

(c)Each 2019 Loan Note Holder hereby irrevocably (i) undertakes, subject to Section 6.11(b), to not transfer any of the 2019 Loan Notes in advance of the 2019 Loan Note Conversion and (ii) consents to the 2019 Loan Note Conversion upon the terms stated herein; and (iii) hereby agrees that with effect from closing of the 2019 Loan Note Conversion, each 2019 Loan Note shall have been duly satisfied and as a result, the terms of the 2019 Loan Note Instrument as applicable to the 2019 Loan Notes constituted thereby, shall be terminated and of no further force or effect as between F-Star and the 2019 Loan Note Holders.

1.7Contingent Value Rights.

(a)Each holder of Company Common Stock of record as of immediately prior to the Closing shall be entitled to (i) one (1) contractual contingent value right (a “STING Agonist CVR”) issued by Company, subject to and in accordance with the terms and conditions of the CVR Agreement in the form of Exhibit E-1 attached hereto (the “STING Agonist CVR Agreement”), and (ii) one (1) contractual contingent value right (a “STING Antagonist CVR”

and, together with the STING Agonist CVR, the “CVRs” and individually a “CVR”) issued by Company, subject to and in accordance with the terms and conditions of the CVR Agreement in the form of Exhibit E-2 attached hereto (the “STING Antagonist CVR Agreement” and, together with the STING Agonist CVR Agreement, the “CVR Agreements”) for each share of Company Common Stock held by such holder.

(b)At or prior to the Closing, Company and F-Star each shall authorize and duly adopt, execute and deliver, and Company will ensure that the Exchange Agent (in its capacity as Rights Agent (as defined in the CVR Agreements)) executes and delivers, the CVR Agreements, subject to any reasonable revisions to the CVR Agreements that are requested by the Exchange Agent (provided that such revisions are not, individually or in the aggregate, detrimental or adverse, taken as a whole, to any holder of a CVR). Company and F-Star shall cooperate, including by making changes to the forms of CVR Agreements, as necessary to ensure that the CVRs are not subject to registration under the Securities Act, the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or any applicable state securities or “blue sky” laws.

1.8Preliminary Consents and Associated Acknowledgments of Sellers.

(a)Sellers (including, for the avoidance of doubt, any Person who becomes a Seller by execution of a Joinder Agreement after the date hereof) hereby, on a several and not joint basis:

(i)consent and agree for the purpose of each applicable provision of the Shareholders’ Agreement, the Articles of Association and otherwise, to the adoption by F-Star of the Closing Articles of Association and to F-Star entering into this Agreement and taking all such actions as may be required for the purpose of effecting the Contemplated Transactions; and

(ii)acknowledge and agree that, for the purpose of the Articles of Association, the Conversion Ratio (as defined in the Articles of Association and as it applies to any share of any class in the capital of F-Star) that is to be applied in connection with the Share Conversion and the Acquisition shall not be subject to any adjustment in accordance with Article 9.7 of the Articles of Association.

(b)Such of the Sellers who are holders of F-Star Series A Preference Shares and F-Star Seed Preference Shares, on a several and not joint basis, hereby consent and agree to the conversion of all of their F-Star Series A Preference Shares and F-Star Seed Preference Shares into F-Star Ordinary Shares in accordance with the terms of this Agreement and such agreement shall hereby be deemed to constitute;

(c)F-Star and Sellers (including, for the avoidance of doubt, any Person who becomes a Seller by execution of a Joinder Agreement after the date hereof), on a several and not joint basis, hereby agree that:

(i)Articles 5 and 6 of the Articles of Association will not apply for the purpose of the Acquisition, with the allocation and distribution of the Proceeds of Sale (as defined in the Articles of Association) as among Sellers to be governed by the terms of this Agreement; and

(ii)subject to and with effect from Closing, the Shareholders’ Agreement will terminate, and each party to the Shareholders’ Agreement shall, prior to the Closing, deliver to the Company a deed of termination to the Shareholders’ Agreement substantially in such form attached as Exhibit F (the “Deed of Termination-Shareholders’ Agreement”) subject to and with effect from Closing, releasing and discharging each other party thereto from all claims or demands under or in connection with the Shareholders’ Agreement.

(d)Each Seller (including, for the avoidance of doubt, any Person who becomes a Seller by execution of a Joinder Agreement after the date hereof) undertakes to F-Star that such Seller will, prior to the Share Conversion, deliver to F-Star for cancellation all original certificates (or an indemnity in a form acceptable to F-Star in respect thereof) for all F-Star Seed Preference Shares and F-Star Series A Preference Shares held by such Seller that are to be converted into F-Star Ordinary Shares pursuant to the Share Conversion.

1.9Delivery of Acquisition Consideration.

(a)Exchange Agent. On or prior to the Closing Date, Company will select Computershare Trust Company N.A. or another reputable bank or trust company reasonably acceptable to F-Star to act as exchange agent in connection with the Acquisition and the other Contemplated Transactions (the “Exchange Agent”). At or prior to the Closing, Company will issue and cause to be deposited with the Exchange Agent, for the benefit of Sellers, for exchange in accordance with this Article 1, through the Exchange Agent, uncertificated book-entries representing such aggregate number of shares of Company Common Stock to be issued pursuant to Section 1.4, and, after the Closing, the Exchange Agent shall be authorized to issue the shares of Company Common Stock in accordance with this Agreement.

(b)Exchange Procedures. On or prior to the Closing, each Seller, as a condition to receiving the applicable Acquisition Consideration, will deliver to the Exchange Agent (i) a duly executed stock transfer form in favor of Company in customary form approved by Company in respect of the F-Star Shares held by such Seller, and (ii) in respect of all F-Star Shares held by such Seller, certificate(s) evidencing title to such shares or an indemnity for any lost certificates made in favor of F-Star and Company in a form reasonably acceptable to Company. As promptly as practicable after receipt by the Exchange Agent from a Seller of the aforementioned stock transfer form and F-Star share certificate(s), together with such other customary documents as may reasonably be required by the Exchange Agent or Company, such Seller shall receive, from the Exchange Agent, in exchange therefor, a number of whole shares of Company Common Stock represented, at such Seller’s election, by book entry or certificated

The F-Star IP Rights that are owned by an F-Star Company and listed in Part 2.7(a)(i) of the F-Star Disclosure Schedule or co-owned by an F-Star Company and listed in Part 2.7(a)(ii) of the F-Star Disclosure Schedule (collectively, “F-Star Registered IP Rights”) are valid and subsisting and have not been found to be invalid or unenforceable by any Governmental Body. No third party is overtly challenging the right, title or interest of an F-Star Company in, to or under the F-Star Registered IP Rights, or the validity, enforceability or claim construction of any F-Star Registered IP Rights, and there is no opposition, cancellation, proceeding, objection or claim pending with regard to any F-Star Registered IP Rights. The F-Star Registered IP Rights are not subject to any outstanding order, judgment, decree or agreement affecting the F-Star Companies’ use thereof or their rights thereto. To the knowledge of F-Star, no valid basis exists for any of the foregoing challenges or claims. To the knowledge of F-Star, all necessary registration, maintenance and renewal fees in respect of the F-Star Registered IP Rights have been paid and all necessary documents and certificates have been filed with the relevant Governmental Body for the purpose of maintaining such F-Star Registered IP Rights.

(e)Each F-Star Company has taken reasonable measures to protect and maintain the confidentiality of the Trade Secrets included in the F-Star Owned IP Rights. The F-Star Companies have not divulged, furnished to or made accessible any of their Trade Secrets to any Person except (x) pursuant to an enforceable written agreement to maintain the confidentiality of such Trade Secrets, (y) to the United States Patent and Trademark Office (or any of its foreign equivalents) or (z) in connection with the filing of an application to obtain patent protection for the embodiment of such Trade Secret, and the F-Star Companies otherwise take and have taken reasonable measures to maintain the confidentiality of their Trade Secrets. All current and former officers and employees of, and consultants and independent contractors, each F-Star Company who has contributed to the creation or development of any material F-Star Owned IP Rights (i) have assigned all of their respective ownership rights in such IP Rights to such F-Star Company pursuant to written agreements that have executed and delivered to such F-Star Company (containing no exceptions or exclusions from the scope of the coverage contained in such F-Star Company’s applicable form agreement) regarding the assignment to such F-Star Company (“IP Assignment Agreements”) and (ii) do not have any claim, right (whether or not currently exercisable) or interest to or in any F-Star Owned IP Rights. To the knowledge of F-Star, no current or former director, officer or employee of, or consultant or independent

contractor to, any F-Star Company has breached any material term of any IP Assignment Agreements. All IP Assignment Agreements have been made available to Company.

(f)To the knowledge of F-Star and except for any statutory exception to infringement, no current activity of any F-Star Company violates or infringes (directly, contributorily, by inducement, or otherwise), misappropriates or violates any IP Rights of any third party or makes unlawful use of any IP Right of any other Person. No infringement, misappropriation, or similar claim is pending or, to the knowledge of F-Star, threatened against any F-Star Company or against any other Person who is or may be entitled to be indemnified, defended, held harmless, or reimbursed by any F-Star Company with respect to such claim. Since January 1, 2015, no F-Star Company has received any written notice nor are any of them subject to any actual or, to the knowledge of F-Star, threatened proceedings, claiming or alleging any of the foregoing.

(g)To the knowledge of F-Star, no F-Star Owned IP Rights are being infringed, misappropriated or unlawfully used by any Person nor has any Person previously infringed, misappropriated or unlawfully used any such F-Star Owned IP Rights.

(h)Neither the execution, delivery or performance of this Agreement by F-Star nor the consummation by Sellers of the Contemplated Transactions will contravene, conflict with or result in the imposition of any additional limitation on the F-Star Companies’ right, title or interest in or to any material F-Star Owned IP Rights.

(i)No funding, facilities, or personnel of any Governmental Body or any public or private university, college or other educational or research institution were used by any F-Star Company to develop or create, in whole or in part, any F-Star Owned IP Rights that would grant any mandatory or compulsory ownership rights. No F-Star Company is now nor has any F-Star Company ever been a member or promoter of, or a contributor to, any industry standards body or similar organization that could require or obligate the F-Star Company to grant or offer to any other Person any license or right to any F-Star Owned IP Rights.

(j)To the knowledge of F-Star, no breach or violation of any electronic or other database containing (in whole or in part) Sensitive F-Star Company Data or any security policy of F-Star has occurred or is threatened, and there has been no unauthorized or illegal use of or access to information systems and/or the Sensitive F-Star Company Data. No Person (including any Governmental Body) has asserted a claim, or otherwise threatened in writing to commence any action, against any F-Star Company alleging a violation of any privacy policy of the F-Star Companies or the applicable Legal Requirements pertaining to privacy and data protection. No F-Star Company has received any written inquiry or complaint from any Governmental Body regarding the collection, use, retention, storage, security, transfer, disposal, disclosure or other processing of Sensitive F-Star Company Data by or for the F-Star Companies.

2.8Compliance with Legal Requirements.

Company is a party or by which an F-Star Company or any of its properties is bound or affected, except for conflicts, defaults or violations which would not, individually or in the aggregate, have an F-Star Material Adverse Effect.

(b)Except as would not, individually or in the aggregate, have an F-Star Material Adverse Effect, the F-Star Companies hold all permits, licenses, authorizations, variances, exemptions, orders and approvals from applicable Governmental Bodies which are necessary to the operation of the business of the F-Star Companies taken as a whole (collectively, the “F-Star Permits”). The F-Star Companies are in compliance in all material respects with the terms of the F-Star Permits. No action, proceeding, revocation proceeding, amendment procedure, writ, injunction or claim is pending or, to the knowledge of F-Star, threatened, which seeks to revoke or limit any F-Star Permit.

Reg. 46191 (September 10, 1991) or for any other Governmental Body to invoke any similar policy.

(e)None of the F-Star Companies and, to the knowledge of F-Star, no Representative of any F-Star Company or Person acting in concert with or on behalf of the F-Star Companies, or any officers, employees or Representatives of the same with respect to any matter relating to any of the F-Star Companies, has: (i) used any funds for unlawful contributions, gifts, entertainment or other unlawful expenses relating to political activity; (ii) made any unlawful payment to foreign or domestic government officials or employees or to foreign or domestic

(f)At no time since January 1, 2018 has any of the F-Star Companies received written notice that any Governmental Body or institutional review board has commenced, or threatened to initiate, any proceeding seeking the suspension or termination of preclinical or clinical research with respect to any product candidate being researched or developed by or on behalf of any of the F-Star Companies, including any action regarding any investigator participating in any such clinical research. F-Star has, prior to the execution of this Agreement, provided or made available to Company all information about material adverse drug experiences since January 1, 2018 obtained or otherwise received by any of the F-Star Companies from any source, in the United States or outside the United States, related to its respective current products or product candidates, including information derived from clinical investigations prior to any market authorization approvals, commercial marketing experience, postmarketing clinical investigations, postmarketing epidemiological/surveillance studies or registries, reports in the scientific literature, and unpublished scientific papers relating to any product or product candidate manufactured, tested, distributed, held or marketed by any of the F-Star Companies or any of their licensees in the possession of any of the F-Star Companies (or to which any of them has access).

Parts 50, 54, 56, 58, and 312, as amended from time to time, and all applicable similar requirements in other jurisdictions, including all requirements relating to protection of human subjects participating in any such clinical studies; provided, however, that the foregoing representation and warranty is made (i) only to F-Star’s knowledge with respect to clinical and preclinical studies conducted by any third party on behalf of the F-Star Companies and (ii) specifically excludes preclinical studies that were not designed to be conducted in accordance with Good Laboratory Practice.

2.9Legal Proceedings; Orders.

(a)Except as set forth in Part 2.9(a) of the F-Star Disclosure Schedule, during the three (3)-year period prior to the date hereof there has not been, and there is no pending, or threatened in writing, Legal Proceeding and, to the knowledge of F-Star, no Person has threatened to commence any Legal Proceeding: (i) that involves any of the F-Star Companies, any business of any of the F-Star Companies or any of the assets owned, leased or used by any of the F-Star Companies; or (ii) that challenges, or that may have the effect of preventing, delaying, making illegal or otherwise interfering with, any of the Contemplated Transactions, in each case as a claimant, defendant or in any other capacity. None of the Legal Proceedings identified in Part 2.9(a) of the F-Star Disclosure Schedule has had or, if adversely determined, would have or result in, either individually or in the aggregate, an F-Star Material Adverse Effect. To the knowledge of F-Star, no event has occurred, and no claim, dispute or other condition or circumstance exists, that would reasonably be expected to give rise to or serve as a basis for the commencement of any Legal Proceeding of the type described in clause (i) or clause (ii) of the first sentence of this Section 2.9(a).

(b)There is no Order to which any of the F-Star Companies, or any of the assets owned or used by any of the F-Star Companies, is subject. To the knowledge of F-Star, no officer or other key employee of any of the F-Star Companies is subject to any Order that

prohibits such officer or other employee from engaging in or continuing any conduct, activity or practice relating to the business of any of the F-Star Companies.

(c)No F-Star Company is unable to pay its debts, within the meaning of section 123 IA 1986 (without any requirement to prove any matter referred to in that section to the satisfaction of the court) or any other legislation analogous to IA 1986 that is applicable to an F-Star Company in its jurisdiction of incorporation, and no F-Star Company has stopped or suspended payment of its debts as they fall due.

Except as set forth on Part 2.10 of the F-Star Disclosure Schedule, no broker, finder or investment banker is entitled to any brokerage, finder’s or other fee or commission in connection with the Contemplated Transactions based upon arrangements made by or on behalf of any of the F-Star Companies. F-Star has furnished to Company accurate and complete copies of all agreements under which any such fees, commissions or other amounts have been paid or may become payable and all indemnification and other agreements related to the engagement of any Persons listed on Part 2.10 of the F-Star Disclosure Schedule.

2.11Employee Benefit Plans.

(a)Part 2.11(a) of the F-Star Disclosure Schedule sets forth, as of the date hereof, a complete and accurate list of each material plan, program, policy, Contract or other arrangement providing for employment, compensation, retirement, pension, deferred compensation, severance, separation, relocation, termination pay, performance awards, bonus, incentive compensation, stock option, stock purchase, stock bonus, phantom stock, stock appreciation right, other equity-based award, supplemental retirement, profit sharing, material fringe benefits, cafeteria benefits, medical benefits, life insurance, disability benefits, accident benefits, salary continuation, accrued leave, vacation, or other material employee benefits, whether written or unwritten, and each other “employee benefit plan” within the meaning of Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), in each case, for current, retired or former employees, directors or consultants of any F-Star Company, which is sponsored, maintained, contributed to, or required to be contributed to by any F-Star Company or with respect to which an F-Star Company has any material Liability (collectively, the “F-Star Employee Plans”).

(b)F-Star has made available to Company true and complete copies of each F-Star Employee Plan and all material related plan documents, including trust documents, plan amendments, Insurance Policies or contracts, summary plan descriptions, and compliance and nondiscrimination tests (including 401(k) and 401(m) tests) for the last three plan years. With respect to each F-Star Employee Plan that is subject to ERISA reporting requirements, F-Star has made available to Company copies of the Form 5500 reports filed by or on behalf of an F-Star Company with respect to any F-Star Employee Plan for the most recent plan year. Each F-Star Employee Plan that is intended to be qualified under Section 401(a) of the Code has received a favorable determination letter from the Internal Revenue Service that remains effective or is entitled to rely on a favorable opinion letter from the Internal Revenue Service on the form of such F-Star Employee Plan, and to F-Star’s knowledge, nothing has occurred since the issuance of each such letter that would reasonably be expected to cause the loss of the tax-qualified status

of any F-Star Employee Plan subject to Section 401(a) of the Code. F-Star has made available to Company the most recent Internal Revenue Service determination or opinion letter issued with respect to each such F-Star Employee Plan, as applicable.

(c)Each F-Star Employee Plan has been maintained and administered in all material respects in accordance with its terms and in material compliance with the requirements prescribed by applicable Legal Requirements (including, where applicable, ERISA and the Code). No F-Star Employee Plan promises or provides retiree medical or other retiree welfare benefits to any person, except to the extent required by Section 4980B of the Code or any similar state or non-U.S. Legal Requirement. With respect to each F-Star Employee Plan, no “reportable event” within the meaning of Section 4043 of ERISA (excluding any such event for which the thirty (30) day notice requirement has been waived under the regulations to Section 4043 of ERISA) has occurred, nor has any event described in Section 4062, 4063 or 4041 or ERISA occurred, in each case, that could reasonably result in material Liability to an F-Star Company. No suit or material administrative proceeding or action is pending, or to the knowledge of F-Star is threatened, against or with respect to any F-Star Employee Plan, including any audit by the Internal Revenue Service or the United States Department of Labor (other than routine claims for benefits arising under such plans).

(d)Neither F-Star nor any ERISA Affiliate of F-Star has ever maintained, established, sponsored, participated in or contributed to, or is or has been obligated to contribute to, or otherwise incurred any Liability under, any “multiemployer plan” (as defined in Section 3(37) of ERISA) or any “pension plan” (as defined in Section 3(2) of ERISA) subject to Title IV of ERISA or Section 412 of the Code.

(e)Other than as specifically contemplated by this Agreement or as set forth in Part 2.11(e) of the F-Star Disclosure Schedule, the consummation of the Acquisition will not, either alone or in combination with another event, (i) entitle any current or former employee or other service provider of any F-Star Company to severance benefits or any other payment (including golden parachute or bonus payments); (ii) accelerate the time of payment or vesting of any such payments or benefits or increase the amount of compensation or benefits due any such employee or service provider; (iii) result in the forgiveness of any indebtedness; or (iv) result in any obligation to fund future benefits under any F-Star Employee Plan. No benefit payable or that may become payable by F-Star in connection with the Contemplated Transactions or as a result of or arising under this Agreement (either alone or in combination with another event) is reasonably likely to constitute an “excess parachute payment” (as defined in Section 280G(b)(1) of the Code) subject to the imposition of an excise Tax under Section 4999 of the Code or the deduction for which would be disallowed by reason of Section 280G of the Code.

(f)On or prior to the date hereof, the F-Star Companies have taken all actions necessary or advisable to assure that upon the consummation of the transactions contemplated by Section 6.15, the Company shall acquire, or F-Star shall have the right to acquire on the Company’s behalf, all F-Star Ordinary Shares issuable upon the exercise of the F-Star Options or issuable upon the vesting of the F-Star RSUs that are not exchanged for Replacement EIP Options or Replacement EIP RSUs, as applicable, in each case free and clear of any Encumbrance.

2.12Title to Assets; Real Property. Except as set forth on Part 2.12 of the F-Star Disclosure Schedule, the F-Star Companies own, and have good, valid and marketable title to, all material tangible assets purported to be owned by them, including all material tangible assets reflected in the books and records of the F-Star Companies as being owned by the F-Star Companies. All of said assets are owned by the F-Star Companies free and clear of any Encumbrances, except for (i) any lien for current Taxes not yet due and payable or for Taxes that are being contested in good faith and for which adequate reserves have been made on the F-Star Financials, (ii) liens that have arisen in the ordinary course of business and that do not (individually or in the aggregate) materially detract from the value of the assets subject thereto or materially impair the operations of any F-Star Company, and (iii) Encumbrances described in Part 2.12 of the F-Star Disclosure Schedule. The F-Star Companies are the lessees of, and hold valid leasehold interests in, all assets purported to have been leased by them, including all assets reflected in the books and records of the F-Star Companies as being leased to the F-Star Companies, and the F-Star Companies enjoy undisturbed possession of such leased assets. The F-Star Companies do not own and have never owned any real property or any interest in real property, except for the leaseholds created under the real property leases identified in Part 2.12 of the F-Star Disclosure Schedule. Part 2.12 of the F-Star Disclosure Schedule sets forth a complete and accurate list of all real property leases to which any F-Star Company is a party, which are each in full force and effect, and with no existing material default thereunder.

2.13Environmental Matters. Each F-Star Company is in compliance with all applicable Environmental Laws, which compliance includes the possession by F-Star of all permits and other authorizations required under applicable Environmental Laws and compliance with the terms and conditions thereof, except where the failure to be in compliance would not, individually or in the aggregate, have an F-Star Material Adverse Effect. Since January 1, 2017, no F-Star Company has received any written notice or other communication (in writing or otherwise), whether from a Governmental Body, citizens group, employee or otherwise, that alleges that any F-Star Company is not in material compliance with any Environmental Law, and, to the knowledge of F-Star, there are no circumstances existing as of the date hereof that would prevent or interfere with any F-Star Company’s material compliance with any Environmental Law in the future. To the knowledge of F-Star: (i) no current or prior owner of any property leased or controlled by any F-Star Company has received any written notice or other communication relating to property owned or leased at any time by any F-Star Company, whether from a Governmental Body, citizens group, employee or otherwise, that alleges that such current or prior owner or any F-Star Company is not in compliance with or has violated any Environmental Law relating to such property and (ii) no F-Star Company has any material liability under any Environmental Law.

2.14Labor Matters.

(a)The document in the Part 2.14(a) Folder in the F-Star Data Room sets forth a true, complete and correct list showing anonymized, non-identifiable details of all employees of the F-Star Companies, including whether classified as exempt or non-exempt for wage and hour purposes, business location, and 2019 actual compensation.

(b)There are no agreements or other arrangements between the F-Star Companies and any trade union or other body representing employees and no notices have been served under the Information and Consultation of Employee Regulations 2004.

(b)F-Star has made available to Company an accurate and complete copy of each Contract listed or required to be listed in Part 2.15 of the F-Star Disclosure Schedule (any such Contract, an “F-Star Contract”). There are no F-Star Contracts that are not in written form. No F-Star Company and, to F-Star’s knowledge, no other party to an F-Star Contract has breached or violated in any material respect or materially defaulted under, or received notice that it has breached, violated or defaulted under, any of the terms or conditions of any of the F-Star Contracts. To the knowledge of F-Star, no event has occurred, and no circumstance or condition exists, that (with or without notice or lapse of time or both) would reasonably be expected to: (i) result in a violation or breach in any material respect of any of the provisions of any F-Star Contract; (ii) give any Person the right to declare a default in any material respect under any F-Star Contract; (iii) give any Person the right to receive or require a rebate, chargeback, penalty or change in delivery schedule under any F-Star Contract; (iv) give any Person the right to accelerate the maturity or performance of any F-Star Contract; or (v) give any Person the right to cancel, terminate or modify any F-Star Contract. The consummation of the Acquisition will not (either alone or upon the occurrence of additional acts or events) result in any material payment or payments becoming due from any F-Star Company to any Person under any F-Star Contract or give any Person the right to terminate or alter the provisions of any F-Star Contract. No Person is renegotiating any material amount paid or payable to any F-Star Company under any

F-Star Contract or any other material term or provision of any F-Star Contract. Each F-Star Contract is valid, binding, enforceable and in full force and effect, and will continue to be valid, binding, enforceable and in full force and effect following the Closing and the consummation of the Acquisition, except as enforceability may be limited by bankruptcy and other similar laws and general principles of equity.

2.16Books and Records. The minute books of the F-Star Companies have been made available to Company and contain accurate summaries, in all material respects, of all meetings of directors (or committees thereof) and shareholders or actions by written consent since January 1, 2018. Each of the share certificate books, registers of shareholders and other corporate registers of the F-Star Companies comply in all material respects with the provisions of all applicable Legal Requirements and are complete and accurate in all material respects.

All premiums due and payable under such Insurance Policies have been paid on a timely basis and each F-Star Company is in compliance in all material respects with all other terms thereof. True, complete and correct copies of such Insurance Policies have been made available to Company.

fringe benefits, cafeteria benefits, medical benefits, life insurance, disability benefits, accident benefits, salary continuation, accrued leave, vacation, or other material employee benefits, whether written or unwritten, and each other “employee benefit plan” within the meaning of Section 3(3) of ERISA, in each case, for current, retired or former employees, directors or consultants of Company or its Subsidiaries, which is sponsored, maintained, contributed to, or required to be contributed to by Company or its Subsidiaries or with respect to which the Company or its Subsidiaries has any material Liability (collectively, the “Company Employee Plans”).

(b)Company has made available to F-Star true and complete copies of each Company Employee Plan and all material related plan documents, including trust documents, plan amendments, Insurance Policies or contracts, summary plan descriptions, and compliance and nondiscrimination tests (including 401(k) and 401(m) tests) for the last three plan years. With respect to each Company Employee Plan that is subject to ERISA reporting requirements, Company has made available to F-Star copies of the Form 5500 reports filed by or on behalf of an Acquiring Company with respect to any Company Employee Plan for the most recent plan year. Each Company Employee Plan that is intended to be qualified under Section 401(a) of the Code has received a favorable determination letter from the Internal Revenue Service that remains effective or is entitled to rely on a favorable opinion letter from the Internal Revenue Services on the form of such Company Employee Plan, and to Company’s knowledge, nothing has occurred since the issuance of each such letter that would reasonably be expected to cause the loss of the tax-qualified status of any Company Employee Plan subject to Section 401(a) of the Code. Company has made available to F-Star the most recent Internal Revenue Service determination or opinion letter issued with respect to each such Company Employee Plan, as applicable.

(c)Each Company Employee Plan has been maintained and administered in all material respects in accordance with its terms and in material compliance with the requirements prescribed by applicable Legal Requirements (including ERISA and the Code).

With respect to each Company Employee Plan, no “reportable event” within the meaning of Section 4043 of ERISA (excluding any such event for which the thirty (30) day notice requirement has been waived under the regulations to Section 4043 of ERISA) has occurred, nor has any event described in Section 4062, 4063 or 4041 or ERISA occurred, in each case, that could reasonably result in material Liability to Company or its Subsidiaries. No suit or material administrative proceeding or action is pending, or to the knowledge of Company, is threatened, against or with respect to any Company Employee Plan, including any audit by the Internal Revenue Service or the United States Department of Labor (other than routine claims for benefits arising under such plans).

(d)Neither Company nor any ERISA Affiliate of Company has ever maintained, established, sponsored, participated in or contributed to, or is or has been obligated to contribute to, or otherwise incurred any Liability under, any “multiemployer plan” (as defined in Section 3(37) of ERISA) or any “pension plan” (as defined in Section 3(2) of ERISA) subject to Title IV of ERISA or Section 412 of the Code.

(e)Other than as specifically contemplated by this Agreement or as set forth on Part 3.12(e) of the Company Disclosure Schedule, the consummation of the Acquisition will not, either alone or in combination with another event, (i) entitle any current or former employee or other service provider of any Acquiring Company to severance benefits or any other payment (including golden parachute or bonus payments); (ii) accelerate the time of payment or vesting of any such payments or benefits or increase the amount of compensation or benefits due any such employee or service provider; (iii) result in the forgiveness of any indebtedness; or (iv) result in any obligation to fund future benefits under any Company Employee Plan. No benefit payable or that may become payable by Company in connection with the Contemplated Transactions or as a result of or arising under this Agreement (either alone or in combination with another event) is reasonably likely to constitute an “excess parachute payment” (as defined in Section 280G(b)(1) of the Code) subject to the imposition of an excise Tax under Section 4999 of the Code or the deduction for which would be disallowed by reason of Section 280G of the Code.

The Acquiring Companies do not own and have never owned any real property, and do not currently hold any interest in real property, except for the leaseholds created under the real property leases identified in Part 3.13 of the Company Disclosure Schedule. The Acquiring Companies are the lessees of, and hold valid leasehold interests in, all assets purported to have been leased by them, including all assets reflected in the books and records of the Acquiring Companies as being leased to the Acquiring Companies, and the Acquiring Companies enjoy undisturbed possession of such leased assets. Part 3.13 of the Company Disclosure Schedule sets forth a complete and accurate list of all real property leases to which any Acquiring Company is a party, which are each in full force and effect, and with no existing material default thereunder.

3.14Environmental Matters. Each Acquiring Company is in compliance with all applicable Environmental Laws, which compliance includes the possession by Company of all permits and other authorizations required under applicable Environmental Laws and compliance with the terms and conditions thereof, except where the failure to be in compliance would not, individually or in the aggregate, have a Company Material Adverse Effect.

(c)Notwithstanding anything to the contrary contained in Section 6.2(b), at any time prior to the Company Stockholder Approval, the Company Board Recommendation may be withdrawn or modified (a “Company Change in Recommendation”) if the board of directors of Company concludes in good faith, after consultation with Company’s outside legal counsel and financial advisors, that as a result of Company’s receipt of an Acquisition Proposal that was not the result of a breach of Section 6.10(a)(i) and that the board of directors of Company has determined in good faith, after consultation with Company’s outside legal and financial advisors, constitutes a Superior Offer, a failure to make a Company Change in Recommendation is reasonably likely to constitute a breach of the fiduciary duties of the board of directors of Company to the Company Stockholders under applicable Legal Requirements; provided, however, that prior to Company taking any action permitted under this Section 6.2(c), Company shall provide F-Star and Sellers with four (4) Business Days’ prior written notice (the “Notice Period”) advising F-Star and Sellers that it intends to effect such withdrawal or modification to the Company Board Recommendation and specifying, in reasonable detail, the reasons therefor (including the information required by Section 6.10(a)(ii)), and during such Notice Period, (i) Company shall negotiate, and cause its Representatives to negotiate, with F-Star in good faith (to the extent F-Star wishes to negotiate) to enable F-Star to determine whether to propose revisions to the terms of this Agreement such that it would obviate the need for Company’s board of directors to effect such withdrawal or modification, and (ii) Company shall consider in good faith any proposal by F-Star or Sellers to amend the terms and conditions of this Agreement in a manner that would make F-Star’s or Sellers’ modified proposal at least as favorable to Company and its stockholders as the Superior Offer. If the board of directors of Company determines that, in accordance with clause (ii) of the immediately preceding sentence, F-Star’s or Sellers’ modified proposal is at least as favorable to Company and the Company Stockholders as the Superior Offer (after taking account any amendment or modification to the terms of such Superior Offer) then the board of directors of Company shall recommend such modified proposal to the Company Stockholders; provided, however, that in the event of any amendment or modification to the terms of such Superior Offer makes it more favorable than the latest modified proposal by F-Star or Sellers, the notification provisions above shall again apply, except that the Notice Period shall be three (3) Business Days rather than four (4) Business Days. It is expressly understood and agreed by all Parties that a “stop, look and listen” or similar communication by the board of directors of Company, or a committee thereof, to the Company’s Stockholders pursuant to Rule 14d-9(f) of the Exchange Act shall not be deemed a Company Change in Recommendation.

(d)Company’s obligation to call, give notice of and hold the Company Stockholders’ Meeting will not be limited or otherwise affected by any Company Change in Recommendation.

(e)Nothing contained in this Agreement will prohibit Company or its board of directors from making any disclosure or statement pursuant to Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act; provided, however, that no Company Change in Recommendation shall be made except in accordance with the terms of this Agreement.

6.3Access to Information; Confidentiality. During the Pre-Closing Period, and upon reasonable notice and subject to restrictions contained in confidentiality agreements to which such Party is subject, Company and F-Star each shall, and shall use commercially reasonable efforts to cause such Party’s Representatives to, afford to the Representatives of the other, reasonable access, during the Pre-Closing Period, to all its properties, books, contracts, commitments and records (including Tax records) and, during such period, Company and F-Star each will furnish promptly to the other all information concerning its business, properties and personnel as such other Party may reasonably request, and each will make available to the other the appropriate individuals (including attorneys, accountants and other professionals) for discussion of the other’s business, properties and personnel as either Party may reasonably request; provided, that, in each case, such access may be subject to such reasonable restrictions as Company or F-Star, as applicable, reasonably determines, in light of the coronavirus (COVID-19) pandemic (taking into account any “shelter-in-place” or similar order issued by a Governmental Body). Any investigation conducted by Company or F-Star pursuant to this Section 6.3 shall be conducted in such a manner as not to interfere unreasonably with the conduct of the business of the other Party. Each Party will keep such information confidential in accordance with the terms of the currently effective confidentiality agreement (the “Confidentiality Agreement”) between F-Star and Company, which agreements the parties agree will continue in full force following the date of this Agreement. Notwithstanding anything herein to the contrary in this Section 6.3, no access or examination contemplated by this Section 6.3 shall be permitted to the extent that it would require any Party or its Subsidiaries to waive the attorney-client privilege or attorney work product privilege, or violate any applicable Legal Requirement; provided, that such Party or its Subsidiary: (i) shall be entitled to withhold only such information that may not be provided without causing such violation or waiver; (ii) shall provide to the other Party all related information that may be provided without causing such violation or waiver (including, to the extent permitted, redacted versions of any such information); and (iii) shall enter into such effective and appropriate joint-defense agreements or other protective arrangements as may be reasonably requested by the other Party in order that all such information may be provided to the other Party without causing such violation or waiver.

6.4Regulatory Approvals and Related Matters.

(a)Each Party will promptly file all notices, reports and other documents required to be filed by such Party with any Governmental Body with respect to the Contemplated Transactions, and submit promptly any additional information requested by any such Governmental Body. Each of F-Star and Company will notify the other promptly upon the receipt of (and, if in writing, share a copy of) any communication received by such Party from, or given by such Party to, any Governmental Bodies and of any material communication

received or given in connection with any proceeding by a private party, in each case in connection with the Contemplated Transactions. Without limiting the generality of the foregoing, the Parties shall, promptly after the date of this Agreement, prepare and file any notification or other document required to be filed in connection with the Acquisition under any applicable foreign Legal Requirement relating to antitrust or competition matters. Company and F-Star shall respond as promptly as is practicable to respond in compliance with: (i) any inquiries or requests received from the Federal Trade Commission or the Department of Justice for information or documentation; and (ii) any inquiries or requests received from any state attorney general, foreign antitrust or competition authority or other Governmental Body in connection with antitrust or competition matters. Each of F-Star and Company will give the other prompt notice of the commencement or known threat of commencement of any Legal Proceeding by or before any Governmental Body with respect to any of the Contemplated Transactions, will keep the other reasonably informed as to the status of any such Legal Proceeding or threat, and, in connection with any such Legal Proceeding, will permit authorized representatives of the other to be present at each meeting or conference relating to any such Legal Proceeding and to have access to and be consulted in connection with any document, opinion or proposal made or submitted to any Governmental Body in connection with any such Legal Proceeding.

(b)Upon the terms and subject to the conditions set forth in this Agreement and subject to this Section 6.4(b), each of the Parties agrees to use its commercially reasonable efforts to take, or cause to be taken, all actions necessary or advisable to satisfy each of the conditions set forth in Article 7, consummate the Acquisition and make effective the other Contemplated Transactions (provided that no Party will be required to waive any of the conditions set forth in Article 7, as applicable, as part of its obligations to consummate the Contemplated Transactions). Without limiting the generality of the foregoing, but subject to this Section 6.4(b), each Party agrees to use its commercially reasonable efforts to: (i) as promptly as practicable, prepare and file all filings (if any) and give all notices (if any) required to be made and given by such Party in connection with the Contemplated Transactions; (ii) obtain each Consent (if any) required to be obtained (pursuant to any applicable Legal Requirement or Contract, or otherwise) by such Party in connection with the Contemplated Transactions; and (iii) lift any restraint, injunction or other legal bar to the Contemplated Transactions.

6.5Director Indemnification and Insurance.

(a)From the Closing through the sixth (6^th) anniversary of the Closing Date, Company 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 Closing, a director or officer of any F-Star Company or Acquiring Company (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 or officer of an F-Star Company or Acquiring Company, whether asserted or claimed prior to, at or after the Closing, to the fullest extent permitted under applicable Legal Requirement, and such F-Star Company’s or Acquiring Company’s Organizational Documents, as applicable. Each D&O Indemnified Party will, to the fullest extent permitted under applicable Legal Requirements and

the F-Star Company’s or Acquiring Company’s Organizational Documents, as applicable, be entitled to advancement of expenses incurred in the defense of any such claim, action, suit, proceeding or investigation from each of the applicable Acquiring Company and the applicable F-Star Company, jointly and severally, upon receipt by Company or F-Star from the D&O Indemnified Party of a request therefor; provided that any person to whom expenses are advanced provides an undertaking, to the extent then required by applicable Legal Requirement, to repay such advances if it is ultimately determined that such person is not entitled to indemnification.

(b)From and after the Closing, Company shall maintain directors’ and officers’ liability insurance policies (at F-Star’s expense) for Company and its Subsidiaries, including F-Star and its Subsidiaries, 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 Company. In addition, prior to the Closing, Company shall purchase and fully pre-pay (at Company’s expense) a “tail” endorsement for the Company’s existing directors’ and officers’ insurance policies and Company’s existing fiduciary liability insurance policies, in each case, that provides a six-year extended reporting period from and after the Closing for claims first made against an individual insured for any alleged or actual wrongful act(s) that occurred prior to the Closing (including in connection with this Agreement or the Contemplated Transactions) (the “D&O Tail”). In the event the D&O Tail is not available to be purchased from the Company’s existing directors’ and officers’ and/or fiduciary liability insurer(s) then the Company shall obtain and fully pre-pay (at Company’s expense) the premium for directors’ and officers’ and fiduciary liability insurance policies which would be the equivalent of the D&O Tail with coverage that is substantially equivalent to and in any event not less favorable than the Company’s current existing directors’ and officers’ and fiduciary liability insurance and which cannot be cancelled for any reason. Additionally, F-Star will obtain run-off “tail” endorsements to its current directors’ and officers’ insurance policies (or runoff or “tail” policies of at least the same coverage containing terms and conditions no less advantageous to the current and all former directors and officers of F-Star) with respect to acts or failures to act prior to the Closing. Company shall (at F-Star’s expense) maintain products liability and human clinical trial liability insurance policies for Company and its Subsidiaries 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 Company, and providing coverage for bodily injury or property damage caused by Company’s or its Subsidiaries’ products, including bodily injury or property damage occurring in connection with human clinical trials, anywhere in the world. In addition, prior to the Closing, Company shall purchase and fully pre-pay (at F-Star’s expense) a “tail” endorsement to Company’s existing global products liability and human clinical trial liability insurance policy that provides a six-year extended reporting period from and after the Closing for claims for alleged bodily injury or property damage that occurred prior to the Closing in connection with any of the Acquiring Companies’ products, including any alleged bodily injury or property damage occurring in connection with human clinical trials (the “Clinical Trial Tail”). In the event the Clinical Trial Tail is not available to be purchased from the Company’s existing global products liability and human clinical trial liability insurer, then Company shall obtain and fully pre-pay (at F-Star’s expense) the premium for products liability and human clinical trial liability insurance which would be the equivalent of the Clinical Trial Tail with coverage that is substantially equivalent to and in any event not less favorable than Company’s current existing products liability and human clinical trial liability insurance and

which cannot be cancelled for any reason. Company shall pay all reasonable expenses, including reasonable attorneys’ fees, that may be incurred by the Persons referred to in this Section 6.5 in connection with their enforcement of their rights provided in this Section 6.5 but only if and to the extent that such Persons are successful on the merits of such enforcement action.

(c)The provisions of this Section 6.5 are intended to be in addition to the rights otherwise available to the current and former officers and directors of F-Star and 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.

(d)This Section 6.5 is intended to be (i) for the benefit of, and shall be enforceable by, the D&O Indemnified Parties, their heirs and personal representatives and shall be binding on F-Star, Company and their respective successors and assigns, (ii) in addition to, and not in substitution for, any other rights to indemnification or contribution that any D&O Indemnified Party may have by contract or otherwise, including indemnification agreements that Company or F-Star have entered into with any of their respective directors or officers, and (iii) may not be amended, altered or repealed after the Closing without the prior written consent of the affected D&O Indemnified Party (provided that, for the avoidance of doubt, such amendment, alteration or repeal prior to the Closing shall be governed by Section 9.2).

(e)In the event Company or F-Star 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 Company or F-Star, as the case may be, shall succeed to the obligations set forth in this Section 6.5.

6.6Notification of Certain Matters.

(a)Company will give prompt notice to F-Star and each Seller, F-Star will give prompt notice to Company and each Seller will give prompt notice to F-Star and Company, of (i) the occurrence, or non-occurrence, of any event the occurrence, or non-occurrence, of which would be likely to cause any representation or warranty contained in this Agreement to be untrue or inaccurate in a manner that causes the condition set forth in Section 7.2(b) or Section 7.3(b), as applicable, not to be satisfied, and (ii) any failure of Company, F-Star or such Seller, as the case may be, materially to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder.

(b)Company, F-Star and each Seller will give prompt notice to the other of: (i) any notice or other communication from any Person alleging that the consent of such Person is or may be required in connection with the Contemplated Transactions; (ii) any notice or other communication from any Governmental Body in connection with the Contemplated Transactions; (iii) any litigation relating to or involving or otherwise affecting Company, F-Star or such Seller that relates to the Contemplated Transactions; (iv) the occurrence of a default or event that, with notice or lapse of time or both, will become a default under a Company Contract or an F-Star Contract, as applicable; and (v) any change that would be considered reasonably

likely to result in a Company Material Adverse Effect or an F-Star Material Adverse Effect, as applicable.

(c)No notification given to a Party pursuant to this Section 6.6 shall change, limit or otherwise affect any of the representations, warranties, covenants or obligations of the Party providing such notification or any of such Party’s Subsidiaries contained in this Agreement or the Company Disclosure Schedule or the F-Star Disclosure Schedule, as appropriate, for purposes of Section 7.2 or Section 7.3, as appropriate. The failure by a Party to give a notification required under this Section 6.6 or any delay in providing such a required notification shall not be treated as a breach of covenant for the purposes of Section 7.2(a) or Section 7.3(a), as applicable, unless such failure or delay results in material prejudice to another Party.

6.7Public Announcements. The initial press release relating to this Agreement shall be a joint press release, and thereafter F-Star and Company will consult with each other before issuing any press release or otherwise making any public statements (including disclosure under the Securities Act or Exchange Act) with respect to the Acquisition or this Agreement. No Party shall, and no Party shall permit any of its Subsidiaries or Representatives to, issue any press release or make any such public statement (to any customers or employees of such Party, to the public or otherwise) relating to the Acquisition without the prior consent of, in the case of (i) Company, F-Star, (ii) F-Star, Company or (iii) a Seller, F-Star and Company, which will not be unreasonably withheld, conditioned or delayed; provided, however, that (A) on the advice of outside legal counsel, Company may issue a press release or public statement without the consent of F-Star if Company, with the advice of outside legal counsel, reasonably determines is required by Legal Requirements or otherwise made in connection with a Company Change in Recommendation or the termination of this Agreement and (B) other than a press release announcing a Company Change in Recommendation or the termination of this Agreement or a subsequent press release relating to such Company Change in Recommendation or termination, any press release or public statement relating to the Acquisition to be issued without the consent of F-Star pursuant to clause (A) shall be subject to reasonable prior notice to and review of F-Star and Company shall consider any and all reasonable comments of F-Star thereon in good faith. Notwithstanding the foregoing, each of Company and F-Star may make public statements in response to specific questions by the press, analysts, investors or those attending industry conferences or financial analyst conference calls, so long as any such statements are consistent with previous press releases, public disclosures or public statements made by Company or F-Star in compliance with this Section 6.7 and such statements do not result in the requirement to amend or supplement the Registration Statement or the Proxy Statement and are not deemed to be a “free-writing prospectus” as such term is defined under the Securities Act. Further, Company may make issue one or more press releases or make public statements relating to the Approved Development Transaction or any Permitted Disposition.

6.8Conveyance Taxes. Each Party will cooperate in the preparation, execution and filing of all returns, questionnaires, applications or other documents regarding any real property transfer or gains, sales, use, transfer, value added, stock transfer and stamp Taxes, any transfer, recording, registration and other fees, and any similar Taxes which become payable in connection with the Contemplated Transactions that are required or permitted to be filed on or before the Closing or in relation to stamp Taxes in respect of the transfers of (or agreement to transfer) the F-Star Shares after the Closing. Without limiting the generality of the forgoing,

Company shall not have any Liability for any Tax incurred by F-Star or any Seller in connection with the Contemplated Transactions.

6.9Board of Directors and Officers. Until successors are duly elected or appointed and qualified in accordance with applicable Legal Requirements, the Parties shall use reasonable best efforts and take all necessary action so that the Persons listed in Schedule 6.9 are elected or appointed, as applicable, to the positions of officers and directors of Company, as set forth therein, to serve in such positions effective as of the Closing. If any Person listed in Schedule 6.9 is unable or unwilling to serve as officer or director of Company, as set forth therein, the Party appointing such Person (as set forth on Schedule 6.9) shall designate a successor.

6.10Non-Solicitation by Company and F-Star.

(a)Non-Solicitation by Company.

(i)Prior to the receipt of Company Stockholder Approval, Company will not and will not authorize or permit any of its Subsidiaries or authorize any Representative of any Acquiring Company, directly or indirectly, to (i) solicit or initiate, or knowingly encourage, induce or facilitate the making, submission or announcement of any Acquisition Proposal or take any action that would reasonably be expected to lead to an Acquisition Proposal, (ii) furnish any nonpublic information regarding any Acquiring Company to any Person in connection with or in response to an Acquisition Proposal or an inquiry or indication of interest that would reasonably be expected to lead to an Acquisition Proposal, (iii) engage in discussions or negotiations with any Person with respect to any Acquisition Proposal, (iv) approve, endorse or recommend any Acquisition Proposal or (v) enter into any letter of intent or similar document or any agreement providing for or otherwise relating to any Acquisition Transaction (other than an Acceptable Company Confidentiality Agreement); provided, however, that prior to obtaining the Company Stockholder Approval, Company may furnish nonpublic information regarding the Acquiring Companies to, and enter into discussions with, any Person in response to an Acquisition Proposal that, after consultation with its outside legal and financial advisors, Company’s board of directors determines in good faith is, or is reasonably expected to result in, a Superior Offer (and is not withdrawn) if (1) such Acquisition Proposal was not the result of a breach of this Section 6.10(a)(i), (2) the board of directors of Company concludes in good faith, after consultation with its outside legal counsel, that a failure to take such action is reasonably likely to constitute a breach of the fiduciary duties of the board of directors of Company to the Company Stockholders under applicable Legal Requirements, (3) prior to furnishing any such information to, or entering into discussions with, such Person, Company gives F-Star written notice of the identity of such Person and of Company’s intention to furnish information to, or enter into discussions with, such Person, and Company receives from such Person an executed confidentiality agreement on terms no more favorable to Company than the confidentiality agreement between F-Star and Company and containing customary limitations on the use and disclosure of all nonpublic written and oral information furnished to such Person by or on behalf of Company (an “Acceptable Company Confidentiality Agreement”), and (4) prior to or simultaneously with

furnishing any such information to such Person, Company furnishes or makes available such nonpublic information to F-Star (to the extent such nonpublic information has not been previously furnished or made available by Company to F-Star). Company shall, and shall cause its Subsidiaries and instruct its and their respective Representatives to, promptly upon the execution of this Agreement cause to be terminated any solicitation, encouragement, discussion or negotiation with or involving any Person (other than F-Star, Sellers and their respective Affiliates) conducted heretofore by Company or any Subsidiary thereof or any of its or their respective Representatives, with respect to an Acquisition Proposal or which could reasonably be expected to lead to an Acquisition Proposal, and, in connection therewith, Company will immediately discontinue access by any Person (other than F-Star, Sellers and their respective Affiliates) to any data room (virtual or otherwise) established by Company or its Representatives for such purpose. Without limiting the generality of the foregoing, Company acknowledges and agrees that in the event any Representative of Company (or its Subsidiaries) takes any action that, if taken by Company (or its Subsidiaries), would constitute a breach of this Section 6.10(a)(i), the taking of such action by such Representative will be deemed to constitute a breach of this Section 6.10(a)(i) by Company for purposes of this Agreement.

(ii)Prior to the receipt of Company Stockholder Approval, Company will promptly (and in no event later than forty-eight (48) hours after receipt of any Acquisition Proposal or any inquiry or indication of interest that Company reasonably expects to lead to an Acquisition Proposal) advise F-Star orally and in writing of any Acquisition Proposal or inquiry or indication of interest that Company reasonably expects to lead to an Acquisition Proposal (including the identity of the Person making or submitting such Acquisition Proposal, inquiry or indication of interest, and the material terms thereof) that is made or submitted by any Person during the Pre-Closing Period. Company will keep F-Star informed, on a prompt basis, in all material respects with respect to the status of any such Acquisition Proposal, inquiry or indication of interest and any modification or proposed modification thereto.

(b)Non-Solicitation by F-Star.

(i)Prior to the receipt of Company Stockholder Approval, F-Star will not and will not authorize or permit any of its Subsidiaries or authorize any Representative of any F-Star Company, directly or indirectly, to (v) solicit or initiate, or knowingly encourage, induce or facilitate the making, submission or announcement of any F-Star Acquisition Proposal or take any action that would reasonably be expected to lead to an F-Star Acquisition Proposal, (w) furnish any nonpublic information regarding any F-Star Company to any Person in connection with or in response to an F-Star Acquisition Proposal or an inquiry or indication of interest that would reasonably be expected to lead to an F-Star Acquisition Proposal, (x) engage in discussions or negotiations with any Person with respect to any F-Star Acquisition Proposal, (y) approve, endorse or recommend any F-Star Acquisition Proposal or (z) enter into any letter of intent or similar document or any agreement providing for or otherwise relating to any transaction described in the definition of “F-Star Acquisition Proposal”, taking into account the proviso in such definition. F-Star shall, and shall cause its Subsidiaries and instruct its and their respective Representatives to, promptly upon the execution of

this Agreement cause to be terminated any solicitation, encouragement, discussion or negotiation with or involving any Person (other than Company and its respective Affiliates) conducted heretofore by F-Star or any Subsidiary thereof or any of its or their respective Representatives, with respect to an F-Star Acquisition Proposal or which could reasonably be expected to lead to an F-Star Acquisition Proposal, and, in connection therewith, F-Star will immediately discontinue access by any Person (other than Company and its respective Affiliates) to any data room (virtual or otherwise) established by F-Star or its Representatives for such purpose. Without limiting the generality of the foregoing, F-Star acknowledges and agrees that in the event any Representative of F-Star (or its Subsidiaries), takes any action that, if taken by F-Star (or its Subsidiaries) would constitute a breach of this Section 6.10(b)(i), the taking of such action by such Representative will be deemed to constitute a breach of this Section 6.10(b)(i) by F-Star for purposes of this Agreement.

(ii)Prior to the receipt of Company Stockholder Approval, F-Star will promptly (and in no event later than forty-eight (48) hours after receipt of any F-Star Acquisition Proposal or any inquiry or indication of interest that F-Star reasonably expects to lead to an F-Star Acquisition Proposal) advise Company orally and in writing of any F-Star Acquisition Proposal or inquiry or indication of interest that F-Star reasonably expects to lead to an F-Star Acquisition Proposal (including the identity of the Person making or submitting such F-Star Acquisition Proposal, inquiry or indication of interest, and the material terms thereof) that is made or submitted by any Person during the Pre-Closing Period. F-Star will keep Company informed, on a prompt basis, in all material respects with respect to the status of any such F-Star Acquisition Proposal, inquiry or indication of interest and any modification or proposed modification thereto.

6.11Restrictions on Transfer.

(a)Each Seller covenants and agrees for the benefit of Company that during the Pre-Closing Period, such Seller will not, directly or indirectly:

(i)offer, sell, transfer (whether by merger, operation of law or otherwise), pledge, hypothecate, encumber, assign, tender or otherwise dispose of, or enter into any contract, option or other arrangement or understanding, directly or indirectly, with respect to the sale, transfer, pledge, hypothecation, encumbrance, assignment, tender or other disposition of any shares in the F-Star Share Capital, any security convertible into or exercisable or exchangeable for, or that represents the right to receive, shares in the F-Star Share Capital (including any 2019 Loan Note), or any interest in any of the foregoing; or

(ii)take any other action with respect to shares in the F-Star Share Capital, any security convertible into or exercisable or exchangeable for, or that represents the right to receive, shares in the F-Star Share Capital, or any interest in any of the foregoing, that would in any way restrict, limit, or interfere with the performance of such Seller’s obligations hereunder or the Contemplated Transactions.

(b)Notwithstanding the foregoing, any Seller may assign or transfer shares of F-Star Share Capital or the 2019 Loan Notes or any other security convertible into or exercisable or exchangeable for, or that represents the right to receive, shares in the F-Star Share Capital, or any interest in any of the foregoing, to any Permitted Transferee, provided, however, that (i) such assignment or transfer is made in accordance with applicable Legal Requirements and in compliance with any contractual restriction upon the assignment or transfer of such shares, securities or interests, including, where applicable, restrictions contained in the Articles of Association, the Shareholders’ Agreement or the 2019 Loan Note Instrument, (ii) such Permitted Transferee has first executed a Joinder Agreement substantially in the form attached hereto as Exhibit G (“Joinder Agreement”), and (iii) if the Seller effecting the assignment or transfer is subject to a Seller Lock-Up Agreement, such Permitted Transferee has executed and delivered to Company a Seller Lock-Up Agreement with respect to the shares, securities or interests assigned or transferred to it. “Permitted Transferee” shall have the meaning ascribed to it in the Articles of Association.

6.12Joinder Agreements; Seller Lock-Up Agreements. F-Star shall cause each Person who is not already a Party and who acquires shares in the F-Star Share Capital or 2019 Loan Notes from F-Star subsequent to the date hereof to become a Party by executing a Joinder Agreement. F‑Star shall use commercially reasonable efforts to cause the Sellers listed on Schedule III-B to execute and deliver Seller Lock-up Agreements.

Subject to the following sentence, prior to the Closing, Company will take all such steps as may be required (to the extent permitted under applicable Legal Requirements and no-action letters issued by the SEC) to cause any acquisition of Company Common Stock (including derivative securities with respect to Company Common Stock) pursuant to this Agreement by each individual who is or will be subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to Company, to be exempt under Rule 16b-3 under the Exchange Act. At least thirty (30) days prior to the Closing Date, F-Star will furnish the following information to Company for each individual who, immediately after the Closing, is reasonably expected to become subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to Company: (a) the number of F-Star Ordinary Shares expected to be held by such individual immediately following the Share Conversion and exchanged for shares of Company Common Stock pursuant to the Acquisition; (b) the number of other derivative securities (if any) with respect to F-Star Shares held by such individual and expected to be converted into shares of Company Common Stock or derivative securities with respect to Company Common Stock in connection with the Acquisition; and (c) CCC and CIK codes for purposes of submitting SEC Section 16 filings.

6.15F-Star Share Incentives. Prior to the Closing, the board of directors of F-Star (and, in the case of the matters described in Sections 6.15(a)(i) to (xi) below, the board of directors of Company) shall have adopted appropriate resolutions (in the case of resolutions to be

adopted by the board of directors of Company, such resolutions to be provided by F-Star) and taken all other actions necessary and appropriate (in the case of the board of directors of Company, only to the extent specifically directed by F-Star) to provide for the following matters and actions described in this Section 6.15.

(a)by mutual written consent of Company and F-Star duly authorized by each of their respective boards of directors;

(b)by either F-Star or Company, after the End Date, if the Acquisition has not been consummated (provided that the right to terminate this Agreement under this Section 8.1(b) will not be available to any Party whose failure to fulfill any obligation under this Agreement has been the cause of or resulted in the failure of the Acquisition to occur on or before such date; provided, further, that the End Date shall be subject to extension to the extent required to permit compliance with the provisions of Section 1.5, including the final determination of Net Cash thereunder; and provided, further, that, in the event that the SEC has not declared effective under the Securities Act the Registration Statement by the date which is sixty (60) days prior to the End Date, each of Company and F-Star shall be entitled to extend the period for termination of this Agreement pursuant to this Section 8.1(b) for an additional sixty (60) days);

(c)by either F-Star or Company if a Governmental Body has issued a non-appealable final order, decree or ruling or taken any other action, in each case having the effect of permanently restraining, enjoining or otherwise prohibiting the Acquisition;

(e)by F-Star upon breach of any of the representations, warranties, covenants or agreements on the part of Company set forth in this Agreement, or if any representation or warranty of Company will have become inaccurate, in either case such that the conditions set forth in Section 7.2(a) or Section 7.2(b) would not be satisfied as of the time of such breach or as of the time such representation or warranty will have become inaccurate; provided if such breach or inaccuracy is curable by Company, then this Agreement will not terminate pursuant to this Section 8.1(e) as a result of such particular breach or inaccuracy unless the breach or inaccuracy remains uncured as of the thirtieth (30^th) day following the date of written notice given by F-Star to Company of such breach or inaccuracy and its intention to terminate this Agreement pursuant to this Section 8.1(e); provided further that no termination may be made pursuant to this Section 8.1(e) solely as a result of the failure of Company to obtain the Company Stockholder Approval (in which case such termination must be made pursuant to Section 8.1(d));

(f)by Company upon breach of any of the representations, warranties, covenants or agreements on the part of F-Star or Sellers set forth in this Agreement, or if any representation or warranty of F-Star or Sellers will have become inaccurate, in either case such that the conditions set forth in Section 7.3(a) or Section 7.3(b) would not be satisfied as of the time of such breach or as of the time such representation or warranty will have become inaccurate; provided if such breach or inaccuracy is curable by F-Star or Sellers, then this Agreement will not terminate pursuant to this Section 8.1(f) as a result of such particular breach or inaccuracy unless the breach or inaccuracy remains uncured as of the thirtieth (30th) day following the date of written notice given by Company to F-Star of such breach or inaccuracy and its intention to terminate this Agreement pursuant to this Section 8.1(f);

(g)by Company, if there will have occurred any F-Star Material Adverse Effect since the date hereof; provided, however, such termination shall only be effective if such F-Star Material Adverse Effect, if curable, is not cured within thirty (30) days following the date of written notice given by Company to F-Star of such F-Star Material Adverse Effect and its intention to terminate this Agreement pursuant to this Section 8.1(g);

(h)by F-Star, if there will have occurred any Company Material Adverse Effect since the date hereof; provided, however, such termination shall only be effective if such Company Material Adverse Effect, if curable, is not cured within thirty (30) days following the date of written notice given by F-Star to Company of the occurrence of such Company Material Adverse Effect and its intention to terminate this Agreement pursuant to this Section 8.1(h);

respect to, a tender or exchange offer related to any Acquisition Proposal in any position taken pursuant to Rules 14d-9 and 14e-2 under the Exchange Act;

(j)by Company, prior to obtaining the Company Stockholder Approval, if (i) Company has received a Superior Offer, (ii) Company has complied in all material respects with its obligations under Section 6.2(c) in order to accept such Superior Offer, (iii) Company concurrently terminates this Agreement and enters into a definitive agreement with respect to such Superior Offer and (iv) Company pays to F-Star the Company Termination Fee in accordance with Section 8.3(b) no later than two (2) Business Days following such termination; or

(k)by Company, if the F-Star Pre-Closing Financing is terminated or does not occur prior to the End Date; provided, however, that the right to terminate this Agreement under this Section 8.1(k) shall not be available to Company where the failure to obtain the F-Star Pre-Closing Financing shall have been caused by the action or failure to act of Company and such action or failure to act constitutes a material breach by Company of this Agreement.

8.2Effect of Termination. In the event of the termination of this Agreement pursuant to Section 8.1, this Agreement will forthwith become void and there will be no Liability on the part of any Party or any of its Affiliates, directors, officers or stockholders except (i) as set forth in Sections 8.2 and 8.3 and (ii) for any Liability for any knowing breach of any representation, warranty, covenant or obligation contained in this Agreement (for purposes of this Section 8.2 and Section 8.3(e), a “knowing breach” is an act or omission with the actual knowledge that such act or omission represents, or would cause, a breach of this Agreement). No termination of this Agreement will affect the obligations of the Parties contained in the Confidentiality Agreement, all of which obligations will, in addition to this Article 8 and in addition to Article 9, survive termination of this Agreement in accordance with its terms.

8.3Expenses; Termination Fees.

(a)Except as set forth in this Section 8.3, all fees and expenses incurred in connection with this Agreement and the Contemplated Transactions will be paid by the Party incurring such expenses, whether or not the Acquisition is consummated. Notwithstanding the foregoing, (A) Company and F-Star shall share equally all fees and expenses, other than attorneys’ and accountants’ fees and expenses, incurred (i) in relation to the filings by the Parties under any filing requirement under any foreign antitrust Legal Requirement applicable to this Agreement and the Contemplated Transactions, (ii) by engagement of a proxy soliciting firm in connection with obtaining approval of the Company Stockholder Approval Matters, (iii) by engagement of the Exchange Agent and (iv) in relation to the printing (e.g., paid to a financial printer) and filing with the SEC of the Registration Statement (including any financial statements and exhibits) and any amendments or supplements thereto; provided, however, that in no event shall F-Star be obligated to bear any such costs and expenses in excess of $50,000, and (B) F-Star shall be solely responsible for all listing fees payable to Nasdaq in connection with the listing of the shares of Company Common Stock to be issued in connection with the Acquisition and reasonable out-of-pocket expenses of Company incurred in connection therewith. Each of the Parties acknowledges that the agreements contained in this Section 8.3 are an integral part of the Contemplated Transactions, without which, the Parties would not enter into this Agreement.

It is understood and agreed that all fees and expenses incurred or to be incurred by Company in connection with the Contemplated Transactions and preparing, negotiating and entering into this Agreement and the performance of its obligations under this Agreement shall be paid by Company in cash at or prior to the Closing.

(b)Company will pay to F-Star a termination fee (the “Company Termination Fee”) in an amount in cash equal to $2,000,000, less any amounts previously paid pursuant to Section 8.3(c), in the event that this Agreement is terminated pursuant to (i) Section 8.1(b), (ii) Section 8.1(d), (iii) Section 8.1(e), (iv) Section 8.1(i) or (v) Section 8.1(j); provided that, in the case of each of clauses (i), (ii) and (iii), an Acquisition Proposal has been publicly announced, disclosed or otherwise communicated to Company’s board of directors after the date hereof and prior to such termination and, within nine (9) months after the date of such termination, Company entered into a definitive agreement with respect to, or consummates, an Acquisition Transaction, such fee to be paid not later than two (2) Business Days after such entry into a definitive agreement or such Acquisition Transaction is consummated; provided that for purposes of this Section 8.3(b) all references in the definition of Acquisition Transaction to 20% shall instead refer to 50%. If this Agreement is terminated by F-Star pursuant to Section 8.1(i), then Company shall pay the Company Termination Fee to F-Star within two (2) Business Days following such termination.

(c)Company shall no later than two (2) Business Days after receipt of reasonable supporting documentation evidencing such fees and expenses reimburse F-Star and Sellers for all fees and expenses (up to $750,000) incurred by F-Star and Sellers in connection with the authorization, preparation, negotiation, execution and performance of this Agreement and the Contemplated Transactions if this Agreement is terminated by either party pursuant to Section 8.1(d).

(d)F-Star will pay to Company a termination fee (the “F-Star Termination Fee”) in an amount in cash equal to $2,000,000 in the event that this Agreement is terminated by Company pursuant to Section 8.1(k).

(e)In the event that F-Star shall be entitled to receive the Company Termination Fee or Company shall be entitled to receive the F-Star Termination Fee, such fee is not a penalty but shall be liquidated damages in a reasonable amount for any and all losses or damages suffered or incurred by F-Star and Sellers, on the one hand, Company, on the other hand, or in connection with the matter forming the basis for such termination. Notwithstanding any other provision of this Agreement to the contrary, other than as provided in this Section 8.3(e), the Parties agree that the payments contemplated by this Section 8.3 represent the sole and exclusive remedies of F-Star and Sellers, on the one hand, and Company, on the other hand, in respect of a termination pursuant to Section 8.1 under circumstances requiring the payment of the Company Termination Fee or the F-Star Termination Fee, as applicable; provided, that this Section 8.3(e) shall not apply where F-Star’s right to terminate this Agreement pursuant to Section 8.1(d), 8.1(e) or 8.1(i) results from, or Company terminates this Agreement pursuant to Section 8.1(j) following, a knowing breach by Company of this Agreement.

(f)If Company or F-Star, as applicable, fails to pay when due any amount payable by Company or F-Star, as applicable, under this Section 8.3, then (i) Company or F-Star

will, as applicable, reimburse F-Star and Sellers, on the one hand, and Company, on the other hand, for all costs and expenses (including fees and disbursements of counsel) incurred in connection with the collection of such overdue amount and the enforcement by the Parties of their rights under this Section 8.3, and (ii) Company or F-Star, as applicable, will pay to F-Star and Sellers, on the one hand, or Company, on the other hand, interest on such overdue amount (for the period commencing as of the date such overdue amount was originally required to be paid and ending on the date such overdue amount is actually paid to the Parties entitled thereto in full) at a rate per annum equal to the “prime rate” (as announced by Bank of America or any successor thereto) in effect on the date such overdue amount was originally required to be paid.

9.2Amendment. This Agreement may be amended by action taken in writing by or on behalf of the respective boards of directors of Company and F-Star; provided that no representation, warranty or covenant in this Agreement with respect to a Seller may be amended in a manner adverse to a Seller unless such amendment applies to all Sellers in the same fashion and the Parties obtain the prior written approval of such amendment from the Seller Majority; provided further that any amendment or waiver of the provisions of Section 6.5 after the Closing which adversely affects the D&O Indemnified Parties must be approved in writing by the D&O Indemnified Parties; and provided further that, after approval of the Acquisition by the Company Stockholder Approval no amendment may be made which by Legal Requirements requires further approval by such stockholders without such further approval.

9.3Headings. The headings contained in this Agreement are for reference purposes only and will not affect in any way the meaning or interpretation of this Agreement.

9.4Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law, or public policy, all other conditions and provisions of this Agreement will nevertheless remain in full force and effect so long as the economic or legal substance of the Contemplated Transactions is not affected in any manner adverse to any Party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties will negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the Contemplated Transactions are fulfilled to the extent possible.

9.5Entire Agreement. This Agreement and the CVR Agreements constitute the entire agreement and supersede all prior agreements and undertakings (other than the Confidentiality Agreement), both written and oral, among the Parties, or any of them, with respect to the subject matter hereof.

9.6Successors and Assigns. This Agreement will be binding upon: (a) Company and its successors and assigns (if any); (b) F-Star and its successors and assigns (if any); and (c) Sellers and their respective heirs, successors and assigns (if any). This Agreement will inure to

the benefit of: (i) Company; (ii) F-Star; (iii) Sellers; and (iv) the respective heirs, successors and assigns (if any) of the foregoing. Neither Company nor F-Star may assign this Agreement or any of its rights, interests or obligations hereunder without the prior written approval of both the other and a Seller Majority, and no Seller may assign this Agreement or any of its rights, interests or obligations hereunder without the prior written approval of Company, F-Star and a Seller Majority (calculated by disregarding the shares in the F-Star Share Capital held by the assigning Seller). Any purported assignment in violation of this Section 9.6 shall be null and void ab initio.

9.7Parties in Interest. This Agreement will be binding upon and inure solely to the benefit of each Party, and nothing in this Agreement, expressed or implied, is intended to or will confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement, other than Section 6.5 (which is intended to be for the benefit of D&O Indemnified Parties and may be enforced by D&O Indemnified Parties). Notwithstanding the foregoing, for the avoidance of doubt, Company shall have the right to enforce this Agreement directly against any Seller in the event of a breach by such Seller of this Agreement.

9.8Waiver. No failure or delay on the part of any Party in the exercise of any right hereunder will impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor will any single or partial exercise of any such right preclude other or further exercise thereof or of any other right. At any time prior to the Closing, any Party may, with respect to any other Party, (a) extend the time for the performance of any of the obligations or other acts, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto and (c) waive compliance with any of the agreements or conditions contained herein. Any such extension or waiver will be valid if set forth in an instrument in writing signed by the Party or Parties to be bound.

9.9Remedies Cumulative; Specific Performance. Except for the matters described in Section 8.3(e) as exclusive remedies, all rights and remedies existing under this Agreement are cumulative to, and not exclusive of, any rights or remedies otherwise available. Each Party agrees that, in the event of any breach or threatened breach by another Party of any covenant, obligation or other provision set forth in this Agreement: (a) such first Party will be entitled, without any proof of actual damages (and in addition to any other remedy that may be available to it) to: (i) a decree or order of specific performance or mandamus to enforce the observance and performance of such covenant, obligation or other provision; and (ii) an injunction restraining such breach or threatened breach; and (b) such first Party will not be required to provide any bond or other security in connection with any such decree, order or injunction or in connection with any related action or Legal Proceeding.

9.10Governing Law; Venue; Waiver of Jury Trial.

(a)This Agreement will be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof.

(b)The Parties hereto agree that any Legal Proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the Contemplated Transactions shall be brought in the Chancery Court of the State of Delaware located in Wilmington, Delaware and any state appellate court therefrom located in Wilmington, Delaware, or, if no such state court has proper jurisdiction, the Federal District Court for the District of Delaware located in Wilmington, Delaware, and any appellate court therefrom. Each Party hereto hereby irrevocably submits to the exclusive jurisdiction of such court in respect of any legal or equitable Legal Proceeding arising out of or relating to this Agreement or the Contemplated Transactions, or relating to enforcement of any of the terms of this Agreement, and hereby waives, and agrees not to assert, as a defense in any such Legal Proceeding, any claim that it is not subject personally to the jurisdiction of such court, that the Legal Proceeding is brought in an inconvenient forum, that the venue of the Legal Proceeding is improper or that this Agreement or the Contemplated Transactions may not be enforced in or by such courts. Each Party hereto agrees that notice or the service of process in any Legal Proceeding arising out of or relating to this Agreement or the Contemplated Transactions shall be properly served or delivered if delivered in the manner contemplated by Section 9.1 or in any other manner permitted by applicable Legal Requirement.

(c)EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE LEGAL REQUIREMENTS, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, SUIT OR OTHER LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE CONTEMPLATED TRANSACTIONS.

9.11Counterparts and Exchanges by Electronic Transmission or Facsimile. This Agreement may be executed in one or more counterparts, and by the different parties hereto in separate counterparts and by facsimile or electronic (i.e., PDF) transmission, each of which when executed will be deemed to be an original but all of which taken together will constitute one and the same agreement.

9.12Attorney Fees. In any action at law or suit in equity to enforce this Agreement or the rights of any of the Parties hereunder, the prevailing party in such action or suit will be entitled to receive a reasonable sum for its attorneys’ fees and all other reasonable costs and expenses incurred in such action or suit upon the judgment in such action or suit becoming final and nonappealable.

9.13Cooperation. Each Party agrees to cooperate fully with the other Parties hereto and to execute and deliver such further documents, certificates, agreements and instruments and to take such other actions as may be reasonably requested by the other Parties hereto to evidence or reflect the Contemplated Transactions and to carry out the intent and purposes of this Agreement and the Contemplated Transactions.

9.15Construction.

(b)The Parties agree that any rule of construction to the effect that ambiguities are to be resolved against the drafting party will not be applied in the construction or interpretation of this Agreement.

(c)As used in this Agreement, the words “include” and “including,” and variations thereof, will not be deemed to be terms of limitation, but rather will be deemed to be followed by the words “without limitation.”
