Milestone #4	[***]	$[***]
Milestone #5	[***]	$[***]
Milestone #6	[***]	$[***]
Milestone #7	[***]	$[***]
Milestone #8	[***]	$[***]
Milestone #9	[***]	$[***]

(ii) Diligence. Purchaser shall use Commercially Reasonable Efforts to select the Product Candidate to be developed as the Other Product not later than twelve (12) months after the Closing and notify the Representative in writing of such selection including the identity of the selected candidate. Following the Closing, until the expiration of the sixth (6th) anniversary thereof, Purchaser shall itself and/or with or through its Affiliates or licensees, as applicable, use Commercially Reasonable Efforts to achieve the Milestone Events in respect of both the HBV Products and Other Products.

(iii) Termination and Substitution of Products. If Purchaser ceases to develop the HBV Product or the initial Other Product (or both), Purchaser will promptly notify Representative, and thereafter Purchaser will, one time for the HBV Product (with twoback-up products) and one time for the Other Product (with oneback-up product), use Commercially Reasonable Efforts to select substitute(s) for such discontinued product(s) from the Product Candidates. If Purchaser ceases all development of any and all HBV Products and abandons HBV as a target for any future Product

Candidates prior to the time that all of Milestones #1 through #5 have been achieved (each such unachieved Milestone, a “Transferred Milestone”) and if Purchaser achieves thereafter the same Milestone Event as the Transferred Milestone (e.g., Regulatory Approval in the US) with respect to another Product Candidate directed against a target which is neither HBV nor the target against which the Other Product is directed (the first such Product Candidate directed to such other target being referred to as “Backup Product A”) then Purchaser shall pay to the Securityholders an amount for achievement of such Transferred Milestone equal to fifty percent (50%) of the amount set forth in the table in Section 1.3(a)(i) above. In addition, if Purchaser achieves thereafter the same Milestone Event as such Transferred Milestone (e.g., Regulatory Approval in the US) with respect to yet another Product Candidate directed against a target which is neither HBV nor the target against which the Other Product or Backup Product A is directed (such other Product Candidate referred to as “Backup Product B”). Purchaser shall pay to the Securityholders the remaining fifty percent (50%) of the amount set forth in the table in Section 1.3(a)(i) for achievement of such Transferred Milestone.

(iv) Nothing herein shall constitute a guarantee by Purchaser of the achievement of any or all of the Milestone Events (including Transferred Milestones). Purchaser’s maximum aggregate liability for any and all breaches by Purchaser of its obligations under this Section 1.3(a) shall be limited to the unpaid portion(s), if any, of the Milestone Payment(s) that Purchaser would have become obligated to pay if Purchaser had exercised the requisite Commercially Reasonable Efforts.

(b) Reporting; Recordkeeping, Audits.

(i) Reporting. Until such time as all Milestone Payments have been paid by Purchaser pursuant to this Section 1.3 (or such earlier time as Purchaser’s diligence obligations shall have terminated in accordance with the provisions of Section 1.3(a)(ii)), Purchaser shall provide the Representative, within thirty (30) calendar days following the end of each calendar year, with a written report summarizing the efforts of Purchaser and its Affiliates to achieve the Milestone Events, progress with respect thereto and the then-current plans for progressing toward the achievement thereof.

(ii) Recordkeeping. Until such time as all Milestone Payments with respect to Milestone #4, Milestone #5, Milestone #8 and Milestone #9 have been paid by Purchaser pursuant to Section 1.3(a)(i) (or such earlier time as Purchaser’s diligence obligations shall have terminated in accordance with the provisions of Section 1.3(a)(ii)) (the “Audit Period”), and thereafter as needed for any audit requested during the Audit Period with respect to such Milestone Events, Purchaser shall, and shall cause each of its Affiliates or licensees to, keep complete and accurate books and records of Net Sales to the extent necessary to ascertain properly and to verify the payments owed hereunder.

(iii) Audits. Upon the written request of the Representative, Purchaser shall, and shall cause its Affiliates to, and shall use diligent efforts to cause any licensee to, permit an internationally recognized independent accounting firm selected by the Representative and reasonably satisfactory to Purchaser (or its licensee, as the case may be), at the Securityholder’s expense (and subject to entry into a customary confidentiality agreement), to have access upon reasonable prior notice and during normal business hours, but no more than once (1) time during any calendar year, to inspect the books and records specified in Section 1.3(b)(ii) for the three (3) preceding years and only if in response to a request made during the Audit Period for the purpose of determining the accuracy of calculations of Net Sales.

(c) Payments.

(i) Purchaser shall pay, less amounts that qualify under subsection (iv) of the definition ofPre-Closing Taxes, or cause to be paid, each Milestone Payment, subject to the

provisions of Section 1.3(c)(ii), in cash to each Securityholder (or, in respect of Optionholders and other Securityholders receiving compensatory payments under applicable Tax Legal Requirements, to the Company for further distribution to the Optionholders or other Securityholders via the Company’s payroll) in accordance with each such Securityholder’s Pro Rata Amount, within the following time periods: (i) for Milestone #1, Milestone #2, Milestone #3, Milestone #6, and Milestone #7, within thirty (30) calendar days after the date of first achievement of such Milestone Event, and (ii) for Milestone #4, Milestone #5, Milestone #8 and Milestone #9, within sixty (60) calendar days after the end of the calendar year in which such Milestone Event is first achieved.

(ii) For the avoidance of doubt, (x) no Milestone Payment may become payable more than one time and (y) Purchaser’s obligation to make each Milestone Payments shall continue indefinitely until either (A) the Milestone Event corresponding to each such Milestone Payment occurs and the payment is made in accordance with this Agreement; or (B) the date of termination of the development and commercialization of the HBV Product or the Other Product to which such Milestone Event relates, whichever occurs first (such period, the “Earnout Period”). Such obligation, however, shall not in any way be construed as extending the period during which Purchaser is obligated to use Commercially Reasonable Efforts pursuant to Section 1.3(a)(ii).

(d) Subsequent Transfers. Until the end of the Earnout Period, Purchaser shall not, directly or through one or more intermediaries (i.e., whether through one or more assignments, one or more levels of licenses and/or sublicenses, any combination thereof or otherwise), license, sublicense, assign or transfer any material Company IP Rights covering an HBV Product or Other Product (other than licensing or sublicensing to third party contractors and service providers such as contract research organizations or contract manufacturing organizations who are not granted the right to sell or market such HBV Product or Other Product), or otherwise transfer or convey the right to market or sell any HBV Product or Other Product, to any Person other than Purchaser or Purchaser’s Affiliates or their direct or indirect subsidiaries, unless:

(i) Either (i) Purchaser elects in writing nonetheless to remain ultimately responsible for the payment of all applicable Milestone Payments, if and as they become due and owing with respect to such HBV Product or Other Product, it being understood that any such third party transferee of the rights to sell or market HBV Product or Other Product must be bound to develop and commercialize such products with diligence obligations substantially equivalent to (and no less onerous than) those set forth in Section 1.3(a)(ii) and Purchaser shall use its commercially reasonable efforts to enforce such obligations; or (ii) such licensee, sublicensee, assignee or transferee agrees in writing to be bound to the applicable provisions of this Section 1.3 (and related definitions and other terms of this Agreement) with respect to the HBV Product or Other Product, as applicable, including the diligence obligations in Section 1.3(a)(ii), and to provide timely information to and to cooperate with Purchaser to allow Purchaser to meet its information reporting obligations pursuant to this Section 1.3; and

(ii) Purchaser provides the Representative written notice of such license, sublicense, assignment, or transfer.

Purchaser will administer the Special Agreements

during the term of each such agreement. Purchaser acknowledges and agrees that if Purchaser’s agreement to a consent, waiver, amendment or other modification of or under any of the Special Agreements is either requested by a party to such Special Agreement or required under the terms of such Special Agreement and such consent, waiver, amendment or other modification will or would reasonably be expected to materially reduce the amount or materially affect the timing of any Pass-Through Payment, then Purchaser shall consult with and obtain the written consent of the Representative to such consent, waiver, amendment or other modification, which consent shall not be unreasonably withheld, conditioned or delayed. Notwithstanding the foregoing, (i) the Representative’s consent shall not be required if such consent, waiver, modification or amendment is necessary to comply with any Legal Requirement; and (ii) if the Representative is unable to fulfill its responsibilities as agent of the Securityholders and a replacement Representative has not been appointed in accordance with Section 8.1(e), then Purchaser shall not be required to obtain the written consent of the Representative for any such consent, waiver, amendment or other modification. For clarity, the Representative’s consent shall not be required for any consent, waiver, amendment or other modification to any Special Agreement except as set forth above.

All such payment will be payable on a quarterly basis after such amounts are received by the Company, in accordance with each Securityholder’s Pro Rata Amount, directly to the Securityholders, except for payments to Securityholders that under applicable Tax Legal Requirements are compensatory, in which case to the Company for further distribution to such Securityholders via the Company’s payroll.

(c) Subsequent Transfer.Nothing in this Section 1.4 shall be construed as in any way limiting Purchaser’s right to sell, assign or otherwise transfer or convey the Special Agreements and any related obligations hereunder provided that the assignee or transferee agrees in writing to be bound to the applicable provisions of this Section 1.4 (and related definitions and other terms of this Agreement) with respect to the Special Agreements.

Each Securityholder shall, on or prior to the Closing, provide Purchaser and the Paying Agent with a properly completed IRS FormW-9 orW-8BEN (or other applicable IRSW-8 Form), and any other forms reasonably requested by Purchaser or the Paying Agent to comply with applicable Tax Legal Requirements (the “Residency Status Forms”). Purchaser and the Paying Agent shall be entitled to deduct and withhold from any amount payable or otherwise deliverable to any Person pursuant to this Agreement such amounts as Purchaser or the Paying Agent may be required to deduct or withhold therefrom under any Legal Requirement. To the extent such amounts are so deducted or withheld and paid over to the proper Governmental Body, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid. Purchaser and the Paying Agent shall use commercially reasonable efforts to timely pay over such amounts to the proper Governmental Body. If a payment is payable (in whole or in part) in consideration other than cash and if the cash portion of any such payment is insufficient to satisfy all required Tax withholding obligations, Purchaser shall retain an amount of thenon-cash consideration otherwise payable equal in value to the amount required to satisfy any applicable withholding taxes (as reasonably determined by Purchaser in reasonable consultation with the applicable payee).

1.8

Post-Closing Working Capital Adjustment.

(a) Within ninety (90) days after the Closing, Purchaser shall prepare and deliver to Representative a statement setting forth its calculation of Closing Working Capital (the “Closing Working Capital Statement”). After receipt of the Closing Working Capital Statement, Representative shall have thirty (30) days (the “Review Period”) to review the Closing Working Capital Statement. During the Review Period, Representative and its accountants shall have full access to the books and records of the Company, the personnel of and work papers prepared by Purchaser and/or its accountants to the extent that they relate to the Closing Working Capital Statement; provided, that such access shall be in a manner that does not interfere with the normal business operations of Purchaser and the Company.

(b) On or prior to the last day of the Review Period, Representative may object to the Closing Working Capital Statement by delivering to Purchaser a written statement setting forth its objections in reasonable detail, indicating each disputed item or amount and the basis for its disagreement therewith (the “Statement of Objections”). If Representative fails to deliver the Statement of Objections before the expiration of the Review Period, the Closing Working Capital Statement and the Post-Closing Adjustment (as defined below) reflected in the Closing Working Capital Statement shall be deemed to have been accepted by Representative. If Representative delivers the Statement of Objections before the

expiration of the Review Period, Purchaser and Representative shall negotiate in good faith to resolve such objections within thirty (30) days after the delivery of the Statement of Objections (the “Resolution Period”) and, if the same are so resolved within the Resolution Period, the Post-Closing Adjustment and the Closing Working Capital Statement with such changes as may have been previously agreed in writing by Purchaser and Representative shall be final and binding. “Post-Closing Adjustment” means the amount equal to the Closing Working Capital minus the Estimated Working Capital.

(c) If Representative and Purchaser fail to reach an agreement with respect to all of the matters set forth in the Statement of Objections before expiration of the Resolution Period, then any amounts remaining in dispute (the “Disputed Amounts” and any amounts not disputed “theUndisputed Amounts”), shall be submitted for resolution to the office of an impartial nationally recognized firm of independent certified public accountants mutually agreed upon by the Representative and Purchaser (the “Independent Accountant”) who, acting as experts and not as arbitrators, shall resolve the Disputed Amounts only and make any adjustments to the Post-Closing Adjustment, as the case may be, and the Closing Working Capital Statement. The parties hereto agree that all adjustments shall be made without regard to materiality. The Independent Accountant shall only decide the specific item under dispute by the parties.

(d) The fees and expenses of the Independent Accountant shall be paid by Representative (on behalf of the Securityholders) and the Purchaser, based upon the percentage of the Disputed Amount that is ultimately determined to be owed to the other party (for example, if 85% of the Disputed Amount is ultimately allocated to the Securityholders, the Purchaser shall pay 85% of the Independent Accountant fees and expenses). Any such fees and expenses payable by the Representative shall be paid from the Representative’s Expense Fund to the extent available, and if not available from Securityholder’s portion of any Post-Closing Adjustment to the extent available.

(e) (i) If the Post-Closing Adjustment is a negative number, Representative and Purchaser shall, within five (5) Business Days after the final determination of the Post-Closing Adjustment, jointly instruct the Escrow Agent to disburse from the Escrow Amount by wire transfer of immediately available funds to Purchaser, the Post-Closing Adjustment amount. (ii) If the Post-Closing Adjustment is a positive number Purchaser shall, within five (5) Business Days after the final determination of the Post-Closing Adjustment, pay such Post-Closing Adjustment amount to the Securityholders based on their Pro Rata Amount, with such payments to be made through the Paying Agent or, in respect of Optionholders and other Securityholders receiving compensatory payments under applicable Tax Legal Requirements, to the Company for further distribution to the Optionholders or other Securityholders via the Company’s payroll.

(f) The amount of any Post-Closing Adjustment shall not bear any interest. Any payments made pursuant to this Section 1.8, shall be treated as an adjustment to the Purchase Price by the parties for Tax purposes, unless otherwise required by Legal Requirement.

1.9

Old Reserves Adjustment.

(a) Promptly following the Closing, the Company, at the cost of the Representative, shall use commercially reasonably efforts to submit requests (one for each of the following subpart (i) and (ii)) for written ruling from the Swiss Federal Tax Administration establishing the following: (i) the amount of the old reserves (“Altreserven” / “vieilles reserves”) within the meaning of the practice of the Swiss Federal Tax Administration as of the Closing (the “Final Old Reserves Amount”), if any, and the applicable final withholding tax rate on distributions of such old reserves (the “Final Withholding Tax Rate”) and (ii) whether current and future losses arising after January 1, 2017 are deductible from the Final Old Reserves Amount, if any.

(b) If (i) the Company receives a tax ruling issued by the Swiss Federal Tax Administration establishing the Final Old Reserves Amount and the Final Withholding Tax Rate, and (ii) the Old Reserves Retainer exceeds the Final Old Reserves Withholding Amount, Purchaser and the Representative shall, within thirty (30) Business Days following receipt of such tax ruling, jointly instruct the Escrow Agent to disburse from the Old Reserves Escrow Amount by wire transfer of immediately available funds to the Securityholders based on their Pro Rata Amount (with such payments to be made through the Paying Agent or, in respect of Optionholders and other Securityholders receiving compensatory payments under applicable Tax Legal Requirements, to the Company for further distribution to the Optionholders or other Securityholders via the Company’s payroll), the Post-Closing Old Reserves Withholding Adjustment Amount less the costs incurred for the ruling application pursuant to Section 1.9(a) above. The “Final Old Reserves Withholding Amount” means the product of the Final Old Reserves Amount and the Final Withholding Tax Rate, and the “Post-Closing Old Reserves Withholding Adjustment Amount” means the amount equal to the Old Reserves Retainer minus the Final Old Reserves Withholding Amount.

(c) If the Company receives a tax ruling issued by the Swiss Federal Tax Administration establishing that current and future losses are deductible from the Final Old Reserves Amount, if any, then within thirty (30) Business Days from the respective approval by the general meeting of the shareholders of the Company of the financial statements for the calendar years 2017 and 2018, the Company and the Representative shall jointly instruct the Escrow Agent to disburse from the Old Reserves Escrow Amount by wire transfer of immediately available funds to the Securityholders based on their Pro Rata Amount (with such payments to be made through the Paying Agent or, in respect of Optionholders and other Securityholders receiving compensatory payments under applicable Tax Legal Requirements, to the Company for further distribution to the Optionholders or other Securityholders via the Company’s payroll), the Post-Closing Old Reserves Loss Benefit applicable to the calendar year covered by such financial statements. “Post-Closing Old Reserves Loss Benefit” means the amount of the losses recognized in the financial statements for the respective calendar year multiplied by the lower of the Final Withholding Tax Rate (if already established according to Section 1.9 (b) above) or thirty-five percent (35%).

(d) Following approval by the general meeting of the shareholders of the Company of the financial statements for the calendar year 2018 and any distribution required pursuant to Section 1.9(c) above, if any, the Company and the Representative shall jointly instruct the Escrow Agent to disburse by wire transfer of immediately available funds to the Purchaser any amount remaining into the Old Reserves Escrow Amount.

If the total amount of such Damages exceeds the Threshold, then the Indemnitees shall be entitled to be indemnified against and compensated and reimbursed for the full amount of all Damages (and not merely the portion of such Damages exceeding the Threshold).

(b) Subject to Section 7.3(c), recourse by the Indemnitees to the portion of the Escrow Fund and the Recoverable Milestone Payments shall be the Indemnitees’ sole and exclusive remedy for monetary Damages resulting from the matters referred to in Section 7.2(a)(i).

Purchaser shall be entitled to recover directly from any Securityholder with a respect to a claim under Section 7.2(a)(i) only to the extent that there are no remaining funds in the Escrow Fund that are not subject to a pending claim. In the event the Indemnitees is recovering directly from any Securityholder, such Securityholder shall be entitled to pay such recovery in any allocation of cash or shares of Purchaser Common Stock such Securityholder desires.

If a Response Notice is not sent to the Indemnitee by the expiration of the Dispute Period, then the Representative shall be conclusively and irrevocably deemed to have agreed that the full Claimed Amount is owed to the Indemnitee. If there is a Contested Amount, the Representative and the Indemnitee shall attempt in good faith to resolve the dispute related to the Contested Amount. If the Indemnitee and the Representative resolve such dispute in writing, then their resolution of such dispute shall be binding on the Securityholders, Purchaser and the other Indemnitees and a settlement agreement stipulating the amount owed to the Indemnitee shall be signed by the Indemnitee and the Representative.

(c) If the Representative and the Indemnitee are unable to resolve the dispute relating to any Contested Amount during the thirty (30) day period commencing upon the delivery of the Response Notice, then either the Indemnitee or the Representative may submit the contested portion of the indemnification claim to the courts located in New York County, New York in accordance with Section 8.8.

7.6 No Double Recovery. No Indemnitee is entitled to recover under any Claim more than once in respect of the same Damages.

7.7 Escrow Fund. At the Closing, and without any act of any Securityholder, Purchaser shall deposit the Escrow Amount with the Escrow Agent.

In all questions arising under this Agreement or the transactions contemplated hereby, the Representative may rely on the advice of counsel, accountants or other skilled persons, and the Representative will not be liable to any Securityholder or any other Person for anything done, omitted or suffered in good faith by the Representative based on such advice of counsel, accountants or other skilled persons, as the case may be. No provision of this Agreement or any

of the transactions contemplated hereby shall require the Representative to expend or risk its own funds or otherwise incur any financial liability in the exercise or performance of any of its powers, rights, duties or privileges under this Agreement, the Escrow Agreement or any of the transactions contemplated hereby and thereby. Furthermore, the Representative shall not be required to take any action unless the Representative has been provided with funds, security or indemnities which, in its determination, are sufficient to protect the Representative against the costs, expenses and liabilities which may be incurred by the Representative in performing such actions.

(g) The Representative Group shall be indemnified, defended and held harmless by the Securityholders from and against any and all losses, claims, damages, liabilities, fees, costs, expenses (including reasonable legal fees and disbursements and costs and including costs incurred in connection with seeking recovery from insurers), judgments, fines or amounts paid in settlement (“Representative Expense”) arising from, based upon or with respect the Representative’s execution and performance of this Agreement, the Escrow Agreement, the Representative Engagement Agreement or any of the Transactions, or otherwise in connection with acting as the Representative, in each case as such Representative Expense is incurred. To the extent any Representative Expenses are not paid or reimbursed from the Representative’s Expense Fund, upon any payment to the Securityholders of the Escrow Amount, the Representative shall have the right to recover the Representative Expenses from such amount before any distribution to the Securityholders, or in the event there are insufficient funds, directly from the Securityholders, severally and not jointly, on a pro rata basis based on their respective Pro Rata Amount. All of the immunities and powers granted to the Representative under this Agreement shall survive the resignation or removal of the Representative or any member of the Advisory Group and the Closing and/or any termination of this Agreement. The powers, immunities and rights to indemnification granted to the Representative Group in this Agreement: (i) are coupled with an interest and shall be irrevocable and survive the death, incompetence, bankruptcy or liquidation of the respective Securityholder and shall be binding on any successor thereto and (ii) shall survive the delivery of an assignment by any Securityholder of the whole or any fraction of his, her or its interest in the Escrow Amount.

(h) To the extent the Representative receives documents, spreadsheets or other forms of information from any party and the Representative is required to deliver any such document, spreadsheet or other form of information to another party, the Representative is not responsible for the content of such materials, nor is the Representative responsible for confirming the accuracy of any information contained in such materials or reconciling the content of any such materials with any other documents, spreadsheets or other information. The Representative shall not be liable to any Securityholder for any apportionment or distribution of payments authorized by it in good faith, and if any such apportionment or distribution is subsequently determined to have been made in error, the sole recourse of any Securityholder to whom payment was due, but not made, shall be to recover from other Securityholders any payment in excess of the amount to which they are determined to have been entitled pursuant to this Agreement; provided, however, that the foregoing recourse limitation shall not apply in any case where such error was due to fraud or willful misconduct by the Representative. The Representative shall be entitled to rely upon the Pro Rata Amount in the Spreadsheet when setting forth any apportionment or distribution of payments required to be made pursuant to this Agreement.

(i) At the Closing, and without any act of any Securityholder, Purchaser shall deposit the Representative’s Expense Fund Amount with the Representative, to be held by the Representative and released on the instructions of the Representative for the payment of Representative Expenses incurred by the Representative in performing its duties pursuant to this Agreement, the Escrow Agreement or the Representative Engagement Agreement. Purchaser will be deemed to have contributed on behalf of each Securityholder, his, her or its Pro Rata Amount of the Representative’s Expense Fund Amount for retention by the Representative. The Representative is not providing any investment

supervision, recommendations or advice and shall have no responsibility or liability for any loss of principal of the Representative’s Expense Fund other than as a result of its gross negligence or willful misconduct. The Securityholders will not receive any interest on the Representative’s Expense Fund and assign to the Representative any such interest. Subject to Advisory Group approval, the Representative may contribute funds to the Representative’s Expense Fund from any consideration otherwise distributable to the Securityholders. As soon as reasonably determined by the Representative that the Representative’s Expense Fund is no longer required to be withheld, any of the Representative’s Expense Fund Amount originally deposited with the Representative at the Closing that has not been used by the Representative pursuant to the terms of this Agreement shall be released by the Representative for distribution by the Paying Agent to the Securityholders, in each case in proportion to their respective Pro Rata Amount of such remaining funds, if any. For the avoidance of doubt, the Representative’s Expense Fund Amount shall not be deemed part of the Escrow Fund and shall not be available to satisfy any indemnification or other obligations to Purchaser hereunder. None of Purchaser or any of its Affiliates shall have any liability or obligation with respect to the use of the Representative’s Expense Fund Amount by the Representative.

8.2 Further Assurances. Each party hereto shall execute and cause to be delivered to each other party hereto such instruments and other documents, and shall take such other actions, as such other party may reasonably request after the Closing for the purpose of carrying out or evidencing any of the Transactions.

8.3 Fees and Expenses. All costs and expenses incurred in connection with this Agreement and the Transactions (including Transaction Expenses) shall be paid by the party incurring such expense.
