On or prior to the last day of the Review Period, the Holder Representative may object to the Closing Statement by delivering to Biota a written statement setting forth the Holder Representative’s objections in reasonable detail, indicating each disputed item or amount and the basis for the Holder Representative disagreement therewith (the “Statement of Objections”). If the Holder Representative fails to deliver the Statement of Objections before the expiration of the Review Period, the Closing Statement and the Post-Closing Adjustment, as the case may be, reflected in the Closing Statement shall be deemed to have been accepted by the Holder Representative. If the Holder Representative delivers the Statement of Objections before the expiration of the Review Period, Biota and the Holder 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 Statement with such changes as may have been agreed in writing by Biota and the Holder Representative, shall be final and binding.

(e) The Holder Representative shall pay (which payment shall be from the Holder Representative’s Fund if there is one) a portion of the fees and expenses of the Independent Accountants equal to 100% multiplied by a fraction, the numerator of which is the amount of Disputed Amounts submitted to the Independent Accountants that are resolved in favor of Biota (that being the difference between the Independent Accountants’ determination and the Holder Representative’s determination) and the denominator of which is the total amount of Disputed Amounts submitted to the Independent Accountants (that being the sum total by which Biota’s determination and the Holder Representative’s determination differ from the determination of the Independent Accountants).

The Independent Accountants shall make a determination as soon as practicable within thirty (30) days (or such other time as the Parties shall agree in writing) after their engagement, and their resolution of the Disputed Amounts and their adjustments to the Closing Statement and/or the Post-Closing Adjustment shall be conclusive and binding upon the Parties.

(f) The post-closing adjustment to the Closing Date Cash Consideration shall be an amount equal to the Estimated Closing Date Cash Consideration as set forth in the Estimated Closing Statement minus the Closing Date Cash Consideration as set forth on the Closing Statement as finally determined under subsection (c) or (d) above (the “Post-Closing Adjustment”). If the Post-Closing Adjustment is a negative number, Biota shall pay to the Paying Agent (i) the Holdback and (ii) an amount in cash equal to the absolute value of the Post-Closing Adjustment (and the Paying Agent shall pay such amounts to the Sellers based upon their Pro Rata Share). If the Post-Closing Adjustment is a positive number, Biota shall retain that portion of the Holdback equal to the absolute value of the Post-Closing Adjustment, and, in the event the Post-Closing Adjustment due by the Sellers to Biota exceeds the Holdback, such amount by which the Post-Closing Adjustment due by the Sellers to Biota exceeds the Holdback shall be paid in cash by the Sellers (based upon their Pro Rata Share) to Biota; provided, that Biota shall have the right to set-off any such amount due by the Sellers to Biota in excess of the Holdback from any Contingent Payment or Royalty that may become due by Biota under this Agreement and reduce the amount of any such Contingent Payment or Royalty due to the Sellers accordingly. If the Post-Closing Adjustment is a positive number that is less than the Holdback, Biota shall pay to the Paying Agent an amount in cash equal to the difference between the Holdback and the Post-Closing Adjustment (and the Paying Agent shall pay such amounts to the Sellers based upon their Pro Rata Share). Any payments made pursuant to this Section 2.4 shall be treated as an adjustment to the Closing Date Cash Consideration by the Parties for Tax purposes, unless otherwise required by Applicable Law.

Section 2.5. Payment of Closing Date Indebtedness and Transaction Expenses. On the Closing Date, upon the terms and conditions of this Agreement, Biota shall pay, in cash by wire transfer of immediately available funds, the Estimated Closing Date Indebtedness and the Estimated Transaction Expenses, in each case in the amount and to the extent set forth in the Estimated Closing Statement delivered hereunder, and pursuant to the wiring instructions provided by the Holder Representative at least one (1) Business Day prior to the Closing; provided, that Biota shall have no obligation to pay on the Closing Date any amount in respect of repayable advances under the OSEO Agreements.

Section 2.6. Treatment of Warrants. Each Warrant that is not exercised and is outstanding immediately prior to the Closing shall be cancelled at and as of the Closing, and the Warrant Holder that owns such Warrant shall receive no distributions or payments in respect of such Warrant or the cancellation thereof pursuant to this Agreement. Prior to the Closing, the Sellers shall cause Anaconda to obtain a written waiver from each Warrant Holder who does not wish to exercise its Warrants prior to the Closing and whose Warrants do not automatically become null and void if not exercised upon the Closing, in substantially the form of Exhibit E (each a “Warrant Waiver”), to be effective on the Closing Date.

Section 2.7. Withholding Tax. Subject to prior consultation with the Holder Representative, Biota shall be entitled to deduct and withhold, and to cause the Escrow Agent to deduct and withhold, from any amounts payable in respect of the Shares, such amount, if any, as Biota or the Escrow Agent may be required to deduct and withhold with respect to the making of such payment under domestic or foreign Tax Law, and shall pay over (or cause to be paid over) such amounts to the proper Taxing Authority. To the extent that amounts are so deducted and withheld in accordance with the preceding sentence and paid to the proper Taxing Authority, such amounts shall be treated for all purposes of this Agreement as having been paid to, or for the benefit of, the former holder of the Shares in respect of which such deduction or withholding was made.

Section 2.8. Contingent Payments; Royalties.

(a) Contingent Payments. As additional consideration for the Shares, but subject to the set-off rights of Biota pursuant to Section 2.9(b), Biota shall make the following payments to the Paying Agent for distribution to the Sellers (each, a “Contingent Payment”):

(i) upon the achievement of the First Milestone, a one-time payment of ** (the “First Milestone Payment”), payable, at Biota’s election at the time the First Milestone Payment is due, subject to Section 2.8(c), either in cash, in shares of Biota Common Stock or in any combination of cash and shares of Biota Common Stock, within thirty (30) days of the achievement of the First Milestone; plus

(ii) upon the achievement of the Second Milestone, a one-time payment of ** (the “Second Milestone Payment”) payable in cash within thirty (30) days of the achievement of the Second Milestone.

For the avoidance of doubt, each of the foregoing First Milestone Payment and Second Milestone Payment shall be payable only once and shall be due irrespective of whether AP611074 or any rights related thereto have been licensed or assigned by Biota to any Person.

(b) Valuation of First Milestone Shares. If the First Milestone Payment becomes due and Biota elects to make any portion of the First Milestone Payment by issuing shares of Biota Common Stock, each First Milestone Share issued by Biota will be deemed to have a value equal to the Reference Market Value with respect to the date on which the First Milestone is achieved.

(c) Issuance Limitation. Notwithstanding anything in this Agreement to the contrary, the total number of shares of Biota Common Stock that may be issued to Sellers under this Agreement shall be limited to an amount equal to 19.99% of the number of outstanding shares of Biota Common Stock as of the date hereof (the “Share Cap”), unless the approval of Biota’s stockholders is obtained to issue a number of shares in excess of the Share Cap (“Stockholder Approval”). The Share Cap shall be appropriately adjusted for any stock dividend, stock split, reverse stock split or similar transaction. For the avoidance of doubt and without prejudice to Section 2.8(d), Biota shall not be required or permitted to issue any shares of Biota Common Stock under this Agreement if such issuance would breach Biota’s obligations under the rules or regulations of The NASDAQ Stock Market.

(d) Required Combination. In the event the First Milestone Payment becomes due and Biota elects to make the First Milestone Payment by issuing shares of Biota Common Stock up to the Share Cap, then Biota undertakes pay to the Paying Agent in addition to the First Milestone Shares an amount in cash equal to the difference between the amount of the First Milestone Payment and the Reference Market Value for the First Milestone Shares being issued.

(e) Royalties.

(i) As additional consideration for the Shares, the Sellers shall be entitled to receive ** (the “Royalty Rate”) of the Net Sales of AP611074 (“Royalties”), on a country-by-country basis, until the latest to occur of (i) the expiration of the last Valid Claim covering the composition of matter, method of use, or formulation of AP611074 in such country, (ii) expiration of marketing exclusivity (such as, e.g., under 42 U.S.C. §262(k)(7)((A) of the U.S. Federal Food, Drug, and Cosmetic Act or Art. 10(1) of EU Directive 2001/83/EC) for AP611074 in such country; and (iii) ten (10) years from the date of the First Commercial Sale of AP611074 in such country; provided, that upon expiration of the last Valid Claim covering the composition of matter, method of use, or formulation of AP611074 in a country, the Royalty Rate for any future Royalties owed by Biota with respect to Net Sales of AP611074 in such country shall be reduced to **; provided, further, that if one (1) generic version of AP611074 is sold in a country, the Royalty Rate for any future Royalties owed by Biota with respect to Net Sales of AP611074 in such country shall be reduced to ** and if two (2) or more generic versions of AP611074 are sold in a country, the Royalty Rate for any future Royalties owed by Biota with respect to Net Sales of AP611074 in such country shall be reduced to **; and provided, further, that if Biota or any of its Affiliates or any Selling Person enters into an agreement with an unaffiliated third party to obtain a license under a Patent or other Intellectual Property rights that is determined by its patent counsel to be reasonably required to avoid the infringement of such third party Patent or Intellectual Property rights in order to manufacture, use or sell AP611074, or shall be subject to a final court or other binding order or ruling or settlement agreement requiring any payments, including the payment of a royalty to an unaffiliated third party Patent holder in respect of manufacture, use or sale of AP611074, then the Royalty Rate for any future Royalties owed by Biota with respect to Net Sales of AP611074 in any country where such an agreement or final court or other binding order or ruling or settlement agreement governs shall be reduced to **.

(ii) Notwithstanding the foregoing, in no event shall any reduction in Royalties as provided in Section 2.8(e)(i) reduce the Royalty Rate to less than **.

(iii) Biota shall pay any Royalties that may be owed pursuant to Section 2.8(e)(i) by delivering the amount of Royalties owed for each calendar year in cash to the Paying Agent for distribution to the Sellers within sixty (60) days following the end of such calendar year.

(f) Contingent Payments and Royalties Not Certain. Each of Biota, Anaconda and each of the Sellers hereby acknowledges that the achievement of the First Milestone and the Second Milestone, as well as the generation of Royalties, is uncertain, and it is therefore not assured that Biota’s obligation to pay any Contingent Payments or Royalties will ever arise, despite Biota’s use of the efforts required pursuant to Section 2.8(g).

(g) Efforts. **.

(h) Nontransferability of Rights to Contingent Payments and Royalties. The right of the Sellers to receive the Contingent Payments and the Royalties pursuant to this Section 2.8 may not be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part, other than through a Permitted Transfer. For the avoidance of doubt, if Biota elects to make any portion of the First Milestone Payment by issuing First Milestone Shares, such First Milestone Shares will not be subject to the restriction provided in the previous sentence, but will be subject to any applicable restrictions on transfer provided in any applicable securities Laws.

(i) Contingent Payments and Royalties an Integral Part of Consideration. The parties acknowledge that the right of the Sellers to receive the Contingent Payments and the Royalties represents an integral part of the consideration the Sellers are receiving in exchange for their Shares and is a significant factor in the willingness of the Sellers to enter into this Agreement.

(j) Tax Treatment. The Parties shall treat the purchase of the Shares as a contingent payment sale for U.S. federal (and state and local, as applicable) income tax purposes. Biota shall determine the portion (if any) of the amounts paid pursuant to this Agreement that will be treated as interest as required under the Code and the Treasury Regulations promulgated thereunder. No Party to this Agreement shall (nor shall any of its respective Affiliates or direct or indirect owners) take any position inconsistent with the determination of Biota described in the preceding sentence on any Tax Return, in connection with any proceeding related to a Tax Return or otherwise, except as may be required pursuant to a “determination” within the meaning of Section 1313(a) of the Code.

Section 2.9. Review Rights; Set-Off.

(a) Review Rights.

(i) From the date of the first sale of AP611074 until the date on which Biota no longer owes Royalties pursuant to Section 2.8(e), Biota shall provide the Holder Representative, within sixty (60) days following the end of each calendar quarter, with written reports of Net Sales which shall include (I) Net Sales, on a country-by-country basis, during such period, (II) gross sales, on a country-by-country basis, during such period, and (III) the units of AP611074 shipped, on a country-by-country basis, during such period.

(ii) Upon the written request of the Holder Representative (which request may not be made more than once in any calendar year), Biota shall, and shall cause its Subsidiaries to, permit an independent public accounting firm of nationally recognized standing (other than any firm that is the financial auditor of or providing consulting services to any Seller that was entitled to receive more than 10% of the Closing Date Cash Consideration; provided, that the foregoing limitation will not apply to Deloitte, PricewaterhouseCoopers, Ernst & Young and KPMG) designated by the Holder Representative and to be engaged by the Holder Representative and Biota pursuant to an engagement letter reasonably acceptable to the Holder Representative and Biota (a “Reviewing Accountant”) to have reasonable access to the books and records of Biota and its Subsidiaries (during regular business hours, upon reasonable advance notice, under reasonable circumstances, subject to restrictions under applicable Law, without undue disruption to the normal business activities of Biota and its Subsidiaries, and subject to the execution of, and compliance with, a confidentiality agreement mutually reasonably acceptable to Biota and such Reviewing Accountant) for the purpose of reviewing the calculations described in the reports referred to in Section 2.9(a)(i) (including the line-items to show the applicable “gross to net” adjustments). For the avoidance of doubt, such Reviewing Accountant shall be permitted only to confirm to the Holder Representative the amount of Net Sales for the periods in question, or report to the Holder Representative and Biota an alternative calculation of Net Sales. No Reviewing Accountant shall be permitted to review any Net Sales for any calendar year which have previously been reviewed by a Reviewing Accountant pursuant to this Section 2.9(a). In the event that the Reviewing Accountant makes a determination that the Net Sales reported by Biota for any calendar year under review are less than 90% of the Net Sales as finally determined by the Reviewing Accountant, then Biota shall pay all expenses of the Reviewing Accountant. In all other circumstances, all expenses of the Reviewing Accountant shall be paid (or reimbursed) by the Holder Representative or as a set-off from Royalties pursuant to Section 2.9(b).

(iii) The Holder Representative agrees that any information delivered to it under this Section 2.9(a) shall be treated as confidential and may be “material non-public information” of Biota for purposes of all securities Laws, and the Holder Representative shall not buy or sell any Biota Common Stock based upon any such information in violation of any securities Laws until such time as such information is disclosed to the public and shall not disclose such information in violation of any securities Laws to any party (except to the Holder Representative’s advisors, employees, counsel, accountants and representatives on a confidential basis, and to the Sellers) until such time as such information is publicly released by Biota.

(b) Right of Set-Off. Notwithstanding anything to the contrary in this Agreement (but subject to the time limitations in Section 9.1, as applicable), the obligation of Biota to make any Contingent Payment or pay any Royalty shall be qualified in its entirety by the right of Biota to reduce the amount of such Contingent Payment or Royalty, provided that a Biota Indemnified Party has given a Claim Notice in accordance with the provisions of Section 9.3, by the amount of any Damages reasonably determined by Biota in good faith to have been incurred or suffered and subject to indemnification pursuant to Section 9.2(a) or Section 9.2(b), or that could reasonably be expected to be incurred or suffered, by any Biota Indemnified Party and subject to indemnification pursuant to Section 9.2(a) or Section 9.2(b), subject to the express limitations on indemnification set forth in ARTICLE IX; provided, that, in the event that Biota exercises its right of set-off pursuant to this Section 2.9(b) with respect to any portion of Damages which have not been finally determined (which term, for purposes of this Section 2.9(b), shall mean a final, non-appealable judgment of a court of competent jurisdiction, a settlement to which the Holder Representative has consented or the written mutual agreement between Biota and the Holder Representative), Biota shall place an amount equal to Biota’s good faith estimate of such Damages into a separate escrow account with the Escrow Agent, or another escrow agent, until the final amount of such Damages is finally determined, at which time an amount equal to the finally determined amount of such Damages in such escrow account shall be released to Biota and the remainder of the funds in such escrow account shall be released to the Paying Agent for distribution to the Sellers. Biota shall provide the Holder Representative prompt written notice of any Damages incurred by Biota for which Biota intends to exercise its right of set-off pursuant to this Section 2.9(b) (including all updates reasonably requested by the Holder Representative as to the status of the underlying claim). To the extent that any amounts of any Contingent Payment or Royalty are set-off in accordance with this Section 2.9(b), such amounts shall be treated for all purposes of this Agreement as having been paid to the Sellers. For the avoidance of doubt, once actually paid to the Sellers, the Contingent Payments and Royalties shall not be recoverable by Biota pursuant to the set-off rights contained in this Section 2.9(b).

Section 2.10. Form of Consideration Payable by Biota.

(a) Biota Common Stock. Subject to the provisions of Section 2.10(c) and Section 2.10(d), the number of Closing Shares which shall be issuable to each of the Sellers at the Closing shall be as set forth on the Closing Date Allocation Schedule.

(b) Biota Common Stock Issued as First Milestone Payment. Subject to the provisions of Section 2.8 and Section 2.10(c), upon its election, Biota may satisfy its obligation to make any portion of the First Milestone Payment by the issuance to each Seller of such Seller’s Pro Rata Share of the First Milestone Shares being issued by Biota, with any fraction of a share of Biota Common Stock being treated as provided in Section 2.10(d) below.

(c) Covenants. Prior to the issuance of any shares of Biota Common Stock pursuant to this Agreement, Biota shall cause the following to occur:

(ii) any and all shares of Biota Common Stock issued pursuant to this Agreement shall be listed on each securities exchange on which similar securities, including as to class and series, issued by Biota are then listed and, if not so listed, such shares shall be listed on The NASDAQ Stock Market, subject only to notice of issuance;

(iii) any and all such shares of Biota Common Stock issued pursuant to this Agreement shall be duly authorized and reserved for issuance, and upon issuance thereof in accordance with this Agreement, be validly issued, fully paid and nonassessable; and

(iv) any and all First Milestone Shares shall be subject to the right contained in Section 7.4 to have Biota register such First Milestone Shares for resale.

(d) No Fractional Shares. Notwithstanding anything to the contrary herein, no certificates or scrip representing fractional shares of Biota Common Stock shall be issued pursuant to this Agreement, but an amount in cash equal to the aggregate Closing Shares Price or Reference Market Value, as applicable, of all such fractional shares shall instead be deposited with the Holder Representative by Biota and shall be an addition to the Holder Representative’s Fund if there is one.

(e) Legend. Any certificate issued to any Seller representing shares of Biota Common Stock that have not been registered under the Securities Act shall be imprinted with the following legend (or the substantial equivalent thereof):

“THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE SOLD OR OTHERWISE DISPOSED OF, IN WHOLE OR IN PART, OTHER THAN PURSUANT TO REGISTRATION UNDER THE SECURITIES ACT, IN ACCORDANCE WITH THE PROVISIONS OF REGULATION S, OR IN CONFORMITY WITH THE LIMITATIONS OF RULE 144 OR OTHER EXEMPTION AS THEN IN EFFECT, WITHOUT FIRST OBTAINING IF REASONABLY REQUIRED BY BIOTA, (I) A WRITTEN OPINION OF COUNSEL SATISFACTORY TO BIOTA, WHICH MAY BE COUNSEL TO BIOTA, TO THE EFFECT THAT THE CONTEMPLATED SALE OR OTHER DISPOSITION WILL NOT BE IN VIOLATION OF THE SECURITIES ACT, OR (II) A ‘NO-ACTION’ OR INTERPRETIVE LETTER FROM THE STAFF OF THE SECURITIES AND EXCHANGE COMMISSION TO THE EFFECT THAT SUCH STAFF WILL TAKE NO ACTION IN RESPECT OF THE CONTEMPLATED SALE OR OTHER DISPOSITION.

HEDGING TRANSACTIONS INVOLVING THESE SECURITIES MAY NOT BE CONDUCTED UNLESS SUCH HEDGING TRANSACTIONS ARE CONDUCTED IN COMPLIANCE WITH THE SECURITIES ACT.”

In the event that any certificate issued to any Seller representing shares of Biota Common Stock is imprinted with the foregoing legend (or a similar legend), Biota shall cause such legends to be removed in connection with any resale of such shares of Biota Common Stock that is made in compliance with, or pursuant to a valid exemption from, the registration provisions of the Securities Act.

(f) Status of Seller. In no event shall Biota issue either Closing Shares or First Milestone Shares to any Seller who is a U.S. Person unless such Seller is (i) an “accredited investor” as defined in Regulation D promulgated under the Securities Act or (ii) a “qualified institutional buyer” as defined in Rule 144A promulgated under the Securities Act ((i) and (ii), an “Accredited Investor”).

(g) Lock-Up Letter. At or prior to Closing, each Seller shall execute a lock-up letter in favor of Biota in the form of Exhibit G hereto (the “Lock-Up Letter”).

At the Closing, Biota shall deposit the Escrowed Shares into an escrow account (the “Escrow Account”) to be held by the Escrow Agent pursuant to the terms of the Escrow Agreement. The Escrowed Shares shall serve as security for the indemnity obligations under Sections 9.2(a) and (b).

(b) Release of Escrow. The Escrow Agreement shall provide that on the date that is eighteen (18) months after the Closing Date (the “Escrow Release Date”), the Escrow Agent shall release the entire Escrowed Shares then remaining in the Escrow Account in accordance with the Closing Date Allocation Schedule, provided, that if prior to the Escrow Release Date, a Biota Indemnified Party has delivered a Claim Notice pertaining to a matter described in Sections 9.2(a) or (b) and such Claim Notice remains unresolved as of the Escrow Release Date, then Biota shall be entitled to instruct the Escrow Agent to retain such portion of the remaining Escrowed Shares as, in Biota’s reasonable judgment, may be necessary to satisfy any unresolved or unsatisfied claims for indemnifiable Damages specified in such Claim Notice.

(c) Escrow Agent Fees and Expenses. Any fees and expenses of the Escrow Agent shall be paid one half by Biota and one half by the Holder Representative (such payment to be made from the Holder Representative’s Fund if there is one). The Sellers shall be entitled to receive, upon the release of the Escrowed Shares, any and all dividends paid by Biota on shares of Biota Common Stock during the period in which the Escrowed Shares are retained in the Escrow Account.

INDEMNIFICATION

Section 9.1. Survival. All covenants and agreements contained in this Agreement that by their nature are required to be performed by the Sellers by or prior to Closing shall expire and will no longer be required to be performed as of the Closing Date; provided, that Biota may make a claim with respect to such covenants for a period of eighteen (18) months following the Closing Date. All covenants contained in this Agreement that by their nature are required to be performed after Closing by any Party hereto shall survive according to their respective terms. The representations and warranties contained in this Agreement (other than the Fundamental Representations and the Specified Representations) shall survive the Closing and continue in full force and effect for the eighteen (18) month period immediately following the Closing Date. The Fundamental Representations shall survive the Closing and continue in full force and effect indefinitely. The Specified Representations shall survive the Closing and continue in full force and effect until sixty (60) days following the expiration of the applicable statute of limitations. Any claim based on fraud or intentional misrepresentation shall survive the Closing and continue in full force and effect indefinitely. Immediately following the last day of each such survival period (the “Survival End Date”), such representations and warranties shall expire automatically. If written notice of a claim has been given in accordance with Section 9.3 prior to the expiration of the applicable representations, warranties, covenants or agreements, then the applicable representations, warranties, covenants or agreements shall survive as to such claim, until such claim has been finally resolved. Following the expiration of a representation, warranty, covenant or agreement, no claim, action, suit or Proceeding may be initiated by any Biota Indemnified Party or Seller Indemnified Party with respect thereto, regardless of any statute of limitations period that would otherwise apply. For the avoidance of doubt, if the Closing does not occur as a result of any condition precedent not being satisfied or waived, none of the Sellers or Biota shall have any Liability whatsoever, including for breach of covenant or otherwise, except with respect to its breach of the obligations surviving termination of this Agreement as set forth in Section 10.3 or for its fraud or willful breach of this Agreement.

Section 9.2. Indemnification.

(a) Following and subject to the occurrence of the Closing, subject to the limitations described in Section 9.1 and Section 9.5, each Seller shall, severally but not jointly, indemnify, defend, and hold harmless each of Biota, its Affiliates, their respective directors, officers and employees, and their respective heirs, successors and assigns (each, a “Biota Indemnified Party” and, collectively, the “Biota Indemnified Parties”), subject to the provisions of this ARTICLE IX, from and against any and all losses, costs, reasonable expenses, claims, damages, actions, suits, proceedings, hearings, investigations, charges, complaints, demands, injunctions, judgments, orders, decrees, rulings, directions, fines, deficiencies, amounts paid in settlement, Liabilities, Taxes, liens, and fees and court costs, including interest, penalties, and reasonable attorneys’, consultants’ and other professional fees and disbursements and reasonable expenses of investigation and enforcement of rights under this Agreement (collectively, “Damages”) incurred by such Biota Indemnified Party that arise out of or result from (i) any breach of any representation or warranty contained in ARTICLE IV of this Agreement, the Deed of Adherence, the Warrant Waivers, and the certificate to be delivered at Closing pursuant to Section 2.12(a)(ix); (ii) any breach of any covenant or obligation in this Agreement that the Sellers are to cause Anaconda to perform at or prior to the Closing; (iii) any breach of any covenant or obligation in this Agreement to be performed by the Holder Representative; (iv) the dispute between Anaconda and Unither regarding an unpaid invoice of €45,488 dated October 20, 2010; (v) any inaccuracies in the Closing Date Allocation Schedule; (vi) any claim from any of the Employees with respect to the termination of their employment agreements pursuant to Section 8.2(k) or any claim for social charges and other similar Taxes from Governmental Authorities related to said terminations; and (vii) the ongoing URSSAF audit of Anaconda. With respect to Damages referred to in Section 9.2(a), each Seller shall only be liable for the portion of such Damages corresponding to its Pro Rata Share.

(b) Following and subject to the occurrence of the Closing, subject to the limitations described in Section 9.1 and Section 9.5, each Seller, severally and not jointly, shall indemnify, defend, and hold harmless the Biota Indemnified Parties from and against any and all Damages incurred by such Biota Indemnified Party that arise out of or relate to (i) any breach of any representation or warranty of such Seller contained in ARTICLE III of this Agreement, the Deed of Adherence, the Warrant Waivers, and the certificate to be delivered at Closing pursuant to Section 2.12(a)(ix); (ii) any Transfer Taxes due by such Seller pursuant to this Agreement; or (iii) any breach of any covenant or obligation in this Agreement to be performed by such Seller.

(c) Following and subject to the occurrence of the Closing, subject to the limitations described in Section 9.1 and Section 9.5, Biota shall indemnify, defend, and hold harmless the Sellers and each of their respective heirs and Affiliates (each, an “Seller Indemnified Party” and, collectively, the “Seller Indemnified Parties,” and, collectively with the Biota Indemnified Parties, the “Covered Parties,” and each, a “Covered Party”) from and against any and all Damages incurred by such Seller Indemnified Party that arise out of or relate to (i) any breach of any representation or warranty made by Biota in ARTICLE V of this Agreement or in any other Transaction Agreement; or (ii) any breach of any covenant or obligation in this Agreement to be performed by Biota.

(d) For the avoidance of doubt, neither Party shall be liable under this Agreement and any Transaction Agreement in respect of any loss of profit, loss of revenue, loss of contract, loss of goodwill, loss of claim, indirect Damages, punitive Damages or consequential Damages, except to the extent such Damages are payable to a Third Party.

Section 9.3. Notice of Claims.

(a) Any Covered Party seeking indemnification hereunder shall, promptly upon becoming aware of a potential claim for indemnification and in all cases prior to the relevant Survival End Date, give to Biota, in the case of a Seller Indemnified Party, or to the Holder Representative, in the case of a Biota Indemnified Party, (the “Indemnifying Party”) a notice (a “Claim Notice”) describing in reasonable detail the facts giving rise to any claims for indemnification hereunder; provided, that failure to give such notice shall not affect such Covered Party’s right to indemnification hereunder except to the extent the Indemnifying Party shall have been materially prejudiced by such failure.

(b) Each Indemnifying Party to whom a Claim Notice is given shall respond to any Covered Party that has given a Claim Notice (a “Claim Response“) within thirty (30) days (the “Response Period“) after the date that the Claim Notice is given. Any Claim Response must either (i) agree to the amount or method of determination set forth in the Claim Notice and to pay such amount to (or on behalf of) such Covered Party by wire transfer of immediately available funds (or release of Escrowed Shares to a Biota Indemnified Party) or (ii) to provide such Covered Party with notice that they disagree with the amount or method of determination set forth in the Claim Notice. If any Indemnifying Party fails to give a Claim Response within the Response Period, such Indemnifying Party shall be deemed not to dispute the claim described in the related Claims Notice. If any Indemnifying Party elects not to dispute a claim described in a Claims Notice, whether by failing to give a timely Claim Response or otherwise, then the amount of such claim shall be conclusively deemed to be an obligation of such Indemnifying Party.

(c) If an Indemnifying Party delivers a Claim Response disputing the claim of indemnification, the Covered Party that has given the Claim Notice and the Indemnifying Party shall attempt in good faith for a period of thirty (30) days after receipt of the Claim Response to resolve such objection. If the Indemnifying Party and the Covered Party shall so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties, and shall be binding and conclusive upon the Indemnifying Party and the Covered Party. If no such agreement can be reached during the 30-day period for good faith negotiation, then upon the expiration of such 30-day period, either the Indemnifying Party or the Covered Party may bring suit in accordance with Section 11.10.

(d) Subject to the terms of the Escrow Agreement, if, pursuant to the procedures described in this Section 9.3, an Indemnifying Party is determined to be obligated to indemnify a Covered Party hereunder, the Indemnifying Party shall pay (or cause to be paid) to such Covered Party the amount to which such Covered Party shall be entitled within thirty (30) days after such amount has been finally determined in accordance with this Section 9.3. Subject to the provisions of this ARTICLE IX, the Biota Indemnified Parties shall be entitled to recover the amount of any Damages from the Escrow Account, in which case Biota and the Holder Representative shall jointly instruct the Escrow Agent to distribute from the Escrow Account a number of Escrowed Shares equal to the amount of any such Damages divided by the Reference Market Value of the Escrowed Shares as of the date when the payment to the Biota Indemnified Parties is due; provided, that if the number of Escrowed Shares to be distributed is not a round number, then such number shall be rounded to the higher round number if the first decimal is equal or superior to five and to the lower round number if such decimal is inferior to five.

Section 9.4. Third Party Claims.

(a) If a Covered Party receives written notice of a claim from a Third Party that such Covered Party believes may result in a claim for indemnification under this ARTICLE IX (a “Third Party Claim”), such Covered Party shall deliver a Claim Notice to the Indemnifying Party in accordance with the provisions of Section 9.3.

(b) So long as the Litigation Conditions are satisfied, the Indemnifying Party shall have the right to assume and control the defense of the Third Party Claim, at its own expense with counsel selected by it and reasonably acceptable to the Covered Party, by delivering written notice of its assumption of such defense to the Covered Party within fifteen (15) Business Days of its receipt of a Claim Notice of such Third Party Claim; provided, however, that the Covered Party shall have the right to retain its own counsel and assume and control the defense of such Third Party Claim, with the reasonable fees and expenses to be paid by the Indemnifying Party, if (i) the Covered Party receives advice from outside counsel that (A) representation of the Covered Party by the counsel retained by the Indemnifying Party would be inappropriate due to actual or reasonably anticipated potential conflicts of interests between such Covered Party and the Indemnifying Party or (B) there may be legal defenses or counterclaims available to the Covered Party that are inconsistent with, different from or in addition to those available to the Indemnifying Party, or (ii) at any time the Litigation Conditions are not satisfied with respect to such Third Party Claim. If the Indemnifying Party assumes and controls the defense of such Third Party Claim, the Indemnifying Party shall keep the Covered Party reasonably apprised of the status of the Third Party Claim (including by providing copies of all pleadings, notices and communications with respect to the Third Party Claim to the extent that receipt of such documents does not affect attorney-client privilege) and the Covered Party shall be entitled to participate in, but not determine or conduct, the defense of, and/or any settlement negotiations with respect to, such Third Party Claim at its sole cost and expense.

(c) If the Litigation Conditions are not satisfied, or if the Indemnifying Party does not assume the defense of the Third Party Claim as described in Section 9.4(b), the Covered Party shall assume and control the defense of such Third Party Claim at the expense of the Indemnifying Party and shall not settle or compromise the Third Party Claim without the prior written consent of the Indemnifying Party, such consent not to be unreasonably withheld, conditioned or delayed. If the Covered Party assumes and controls the defense of such Third Party Claim, the Covered Party shall keep the Indemnifying Party reasonably apprised of the status of the Third Party Claim (including by providing copies of all pleadings, notices and communications with respect to the Third Party Claim to the extent that receipt of such documents does not affect attorney-client privilege) and the Indemnifying Party shall be entitled to participate in, but not determine or conduct, the defense of, and/or any settlement negotiations with respect to, such Third Party Claim at its sole cost and expense.

(d) If the Indemnifying Party has assumed and controls the defense of the Third Party Claim in accordance with Section 9.4(b), then (i) the Covered Party shall not settle or compromise the Third Party Claim without the prior written consent of the Indemnifying Party, such consent not to be unreasonably withheld, conditioned or delayed and (ii) the Indemnifying Party shall not (A) settle or compromise the Third Party Claim or consent to the entry of any judgment which does not include an unconditional written release by the claimant or plaintiff of the Covered Party from all Liability in respect of such Third Party Claim, or (B) settle or compromise the Third Party Claim if the settlement imposes equitable remedies or material obligations on the Covered Party other than financial obligations for which such Covered Party will be indemnified hereunder, in each case, without the prior written consent of the Covered Party. In each case, the party that is not controlling the defense of the Third Party Claim shall reasonably cooperate with the party that is controlling the defense of such Third Party Claim, at the non-controlling party’s expense, and shall make available to the controlling party all pertinent information under the control of the non-controlling party.

Section 9.5. Limitation on Indemnity. Notwithstanding anything to the contrary contained in this Agreement:

(a) No amount payable by either Biota or the Sellers pursuant to Section 9.2(a)(i), Section 9.2(b)(i) or Section 9.2(c)(i) shall become due until and unless the Damages in respect of any individual claim or series of related claims exceeds $10,000 (the “De Minimis Amount”); provided, however, that any series of related claims shall be considered as one single claim for the purposes of the De Minimis Amount; and provided, further, that the De Minimis Amount shall not apply to breaches of Fundamental Representations or with respect to fraud or intentional misrepresentation.

(b) No amount payable by either Biota or the Sellers pursuant to Section 9.2(a)(i), Section 9.2(b)(i) or Section 9.2(c)(i) shall become due until and unless the aggregate amount of all Damages shall exceed $160,000 (the “Threshold”), whereupon Biota or the Sellers, as applicable, shall be liable for the relevant Damages from the first dollar; provided, however, that the Threshold shall not apply to breaches of Fundamental Representations or with respect to fraud or intentional misrepresentation. In calculating whether the Threshold has been exceeded, only individual claims or series of related claims in excess of the De Minimis Amount shall be considered.

(c) The maximum aggregate amount of Damages for which indemnity may be recovered by the Biota Indemnified Parties from the Sellers pursuant to Section 9.2(a)(i) and Section 9.2(b)(i) shall be an amount equal to $3,200,000 (the “Cap”). The Cap shall not apply to any claim by any Biota Indemnified Party against the Sellers pursuant to Section 9.2(a)(ii) through (vii) or Section 9.2(b)(ii) or (iii), for breaches of Fundamental Representations, or with respect to fraud or intentional misrepresentation. Notwithstanding the foregoing, no Seller shall be liable for Damages pursuant to Section 9.2(a)(ii) through (vii) or Section 9.2(b)(ii) or (iii) or for breaches of Fundamental Representations in an amount in excess of the Total Consideration which such Seller has actually received hereunder (subject to the right of Biota under Section 2.9(b) to set-off from any future Contingent Payments or Royalties due to such Seller any Damages that a Biota Indemnified Party would be entitled to from such Seller but for this limitation).

(d) The maximum aggregate amount of Damages for which indemnity may be recovered by the Seller Indemnified Parties from Biota pursuant to Section 9.2(c)(i) shall be $3,200,000; provided, however, that this Section 9.5(d) shall not limit in any way Biota’s obligation to pay the Sellers the Closing Date Consideration, the Contingent Payments or the Royalties. Biota shall not be liable for Damages pursuant to Section 9.2(c)(ii) in an amount in excess of the Total Consideration Biota has actually paid hereunder.

(e) The right to indemnification or other remedy based on the representations, warranties, covenants, obligations and agreements herein will not be affected or deemed waived by reason of any investigation or audit made by or on behalf of any party (including by any of its Representatives) or by reason of the fact that such party or any of its Representatives knew or should have known that any such representation or warranty is, was or might be inaccurate.

(f) To the extent permitted by Applicable Law, any payment made by an Indemnifying Party to a Covered Party pursuant to this ARTICLE IX shall be treated on the Parties’ Tax Returns and otherwise as an adjustment to the Total Consideration for all Tax purposes.

(g) For purposes of calculating the amount of Damages incurred out of or relating to any breach of a representation or warranty contained in ARTICLE III, ARTICLE IV or any Transaction Agreement delivered by any Seller or the Holder Representative, the references to “Material Adverse Effect,” “material,” “in all material respects” or other materiality qualifications (or correlative terms), including as expressed in accounting concepts, shall be disregarded.

(h) No Seller shall have, exercise or assert (or attempt to exercise or assert), any right of contribution, right of indemnity or other right or remedy against Biota or Anaconda, or any of their respective directors, officers, employees, Affiliates, agents, attorneys, Representatives, assigns or successors, for any indemnification claims asserted by any Biota Indemnified Parties in connection with any indemnification obligation or any other Liability to which such Seller may become subject under or in connection with this Agreement, it being acknowledged that the representations, warranties, covenants and agreements of the Sellers are solely for the benefit of the Biota Indemnified Parties.

Section 9.6. Order of Recovery. Subject to Section 9.5, if the Sellers shall be obligated to indemnify the Biota Indemnified Parties with respect to a claim for Damages pursuant to Section 9.2(a)(i), recovery and payment therefore shall be made first from the Escrowed Shares and then, to the extent that the Reference Market Value of the then-remaining Escrowed Shares is insufficient to fully indemnify the Biota Indemnified Parties for such Damages, the Biota Indemnified Parties shall have the right to (a) seek recovery and payment of such Damages directly against each Seller for an amount not to exceed such Seller’s Pro Rata Share of $1,200,000 and/or (b) set-off such Damages from any future Contingent Payments or Royalties pursuant to Section 2.9(b).

Section 9.7. Treatment of Insurance. With respect to each claim for indemnification, any Damages that may be recovered by the Covered Party with respect to such claim shall be net of any insurance proceeds actually received with respect thereto (net of the out-of-pocket costs reasonably incurred in pursuing or obtaining such insurance proceeds, deductibles and any increased premium amounts directly attributable to such claim). To the extent that insurance proceeds are actually collected after an indemnification claim has been settled, the Covered Party shall restore the Indemnifying Party to the same economic position as would have existed had such insurance proceeds been collected prior to the settlement of such indemnification claim (net of the out-of-pocket costs reasonably incurred in pursuing or obtaining such insurance proceeds, deductibles and any increased premium amounts directly attributable to such claim).

Section 9.8. Tax Benefit. To the extent a Damage gives rise to a Tax benefit or saving in the form of an actual and effective reduction in the corporate tax paid by Anaconda or Biota with respect to the tax year during which such Damage is recorded in the accounts of Anaconda (including, without limitation, a Tax reduction or loss, basis adjustment and/or shifting income, deductions, gains, loss and/or credits but to the exclusion of any increase in the amount of available tax losses carried forward or carried back), the amount of the Damage shall be reduced by the amount of such actual and effective reduction. In determining the amount of such Tax benefit or saving during the fiscal year in which the Loss is recorded in the accounts of Anaconda, the impact of any allowance or cancellation of reserves by Anaconda shall be neutralized.

Section 9.9. Reserves. The amount of the indemnification/price reduction obligation of the Sellers with respect to any Damage shall be reduced by the amount of the reserves included in the Financial Statements to the extent such reserves are directly and specifically related to such Damage.

Section 9.10. Changes in Laws. The Sellers shall not be held liable for Damages directly and exclusively arising (i) from changes in Laws applicable to the operations of Anaconda not in force on or prior to the Closing Date, (ii) post-Closing reorganizations, or (iii) changes in accounting policies or procedures of Anaconda, Biota or its Affiliates applied after the Closing Date.

Section 9.11. Duty to Mitigate. Each Covered Party shall be responsible for taking or causing to be taken all commercially reasonable steps to mitigate its Damages upon and after becoming aware of any event or condition that could reasonably be expected to give rise to any Damages that are indemnifiable under this ARTICLE IX.

Section 9.12. Remedies. The remedies in this ARTICLE IX shall be the sole and exclusive remedies of the Parties with respect to any breach of the respective representations, warranties, covenants, obligations and agreements pursuant to this Agreement or otherwise arising out of this Agreement, regardless of the theory or cause of action pled, except for the remedies of specific performance, injunction and other equitable relief; provided, however, that no party shall be deemed to have waived any rights, claims, causes of action or remedies, and the limitations set forth in Section 9.5 shall not limit any recovery related thereto, if and to the extent fraud or intentional misrepresentation is proven on the part of a party by another party or such rights, claims, causes of action or remedies may not be waived under Applicable Law; provided, further, that in the event fraud or intentional misrepresentation is proven, each Seller shall be liable for Damages under Section 9.2(b) in excess of the Cap only to the extent such Damages arise out of such fraud or intentional misrepresentation committed by such Seller.

Section 9.13. Duplication. Any liability for indemnification hereunder shall be calculated without duplication by reason of the same set of facts giving rise to such liability constituting a breach of more than one representation, warranty, covenant, obligation or agreement.

ARTICLE X.

Section 11.3. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK, IRRESPECTIVE OF THE CHOICE OF LAWS PRINCIPLES OF THE STATE OF NEW YORK, AS TO ALL OTHER MATTERS, INCLUDING MATTERS OF VALIDITY, CONSTRUCTION, ENFORCEABILITY, PERFORMANCE AND REMEDIES.

Section 11.4. Entire Agreement; Amendments and Waivers. This Agreement, the Confidentiality Agreement and the other documents and instruments referred to herein and all exhibits and schedules hereto, constitutes the entire agreement among the Parties pertaining to the subject matter hereof and supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written, of the Parties. Any provision of this Agreement may be amended or waived if, but only if such amendment or waiver is in writing and is signed by Biota and the Holder Representative (it being acknowledged and agreed that the Holder Representative may amend this Agreement and waive matters on behalf of the Sellers, all as contemplated by Section 11.5 hereof). No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provision hereof (whether or not similar), nor shall such waiver constitute a continuing waiver unless otherwise expressly provided. No failure on the part of any party to exercise, and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of such right, power or remedy by such party preclude any other or further exercise thereof or the exercise of any other right, power or remedy.

Section 11.5. Appointment of the Holder Representative.

(a) Appointment. As used in this Agreement, the term “Holder Representative” shall mean that Person designated by the Sellers who were entitled to receive a majority of the Closing Date Cash Consideration (a “Majority of Sellers”), who shall initially be Xx. Xxxxx Xxxxxxxxxx, or any Person appointed as a successor Holder Representative pursuant to Section 11.5(b). By execution hereof, the Holder Representative hereby accepts its appointment as the initial Holder Representative. Effective upon the execution of this Agreement, without any further action by any other Person, the Holder Representative shall be appointed and constituted in respect of each Seller, as his, her or its agent, to act in his, her or its name, place and stead, as such Seller’s attorney-in-fact, as more fully set forth in Section 11.5(c).

(b) Election and Replacement. From and after the execution of this Agreement until the date when all obligations under this Agreement have been discharged (including all indemnification obligations under ARTICLE IX), a Majority of Sellers may, from time to time upon written notice to the Holder Representative and Biota, (i) remove any Holder Representative (including any Holder Representative appointed by Biota as provided below) or (ii) appoint a new Holder Representative to fill any vacancy created by the death, incapacitation, resignation or removal of any Holder Representative. If a Majority of Sellers is required to but has not appointed a successor Holder Representative to fill any vacancy within thirty (30) days after Biota has sent a written notice to a Majority of Sellers requesting that they appoint a successor Holder Representative, Biota shall have the right to appoint a Holder Representative to fill any such vacancy; provided, however, that a Majority of Sellers shall thereafter retain the right to remove the Holder Representative or appoint a new Holder Representative pursuant to this Section 11.5(b). A copy of any appointment by a Majority of Sellers of any successor Holder Representative shall be provided to Biota promptly after it shall have been effected. Each successor Holder Representative shall have all of the power, authority, rights and privileges conferred by this Agreement upon the original Holder Representative, and the term “Holder Representative” as used herein shall be deemed to include any successor Holder Representative.

(c) Authority. The Holder Representative shall be authorized, on behalf of each and every Seller, (i) to execute, as Holder Representative, this Agreement and any agreement or instrument entered into or delivered in connection with the transactions contemplated hereby (including, for the avoidance of doubt, the Disclosure Letter for and on behalf of the Sellers); (ii) to discuss, negotiate, agree to, enter into, consent to, resolve and fully and finally settle on behalf of the Sellers any claims for indemnification by any Biota Indemnified Party under ARTICLE IX hereof, including the authorization to comply with Court Orders with respect to any such claim for indemnification and the delivery to Biota of cash from the Escrow Account in satisfaction of claims asserted by Biota pursuant to ARTICLE IX hereof; (iii) to object to such claims pursuant to Section 9.3; (iv) to take any action, including litigating, prosecuting, defending or enforcing any actions or demanding arbitration, and to make, deliver and sign any certificate, notice, consent or instrument required or permitted to be made or delivered under this Agreement or under the documents referred to in this Agreement (an “Instrument”) which the Holder Representative determines in its discretion to be necessary, appropriate or desirable (provided, that if any individual Seller is named in such litigation, such Seller shall have the right to tender defense); (v) to hire or retain, at the sole expense of the Sellers, such counsel, investment bankers, accountants, representatives and other professional advisors as it determines in its sole and absolute discretion to be necessary, advisable or appropriate; (vi) to act as, or retain a, paying agent for the Closing Date Cash Consideration and any post-closing distribution of the Escrowed Shares, the Contingent Payments or Royalties; (vii) to consent or agree to any amendment to this Agreement or to waive any terms and conditions of this Agreement providing rights or benefits to the Sellers in accordance with the terms hereof and in the manner provided herein; (viii) to receive all documents, certificates and notices and make all determinations on behalf of the Sellers required under this Agreement; and (ix) to take all other actions to be taken by or on behalf of any Seller in connection herewith, and to do each and every act and exercise any and all rights which a Seller is, or the Sellers collectively are, permitted or required to do or exercise under this Agreement in each case without having to seek or obtain the consent of any Person under any circumstance. A decision, act, consent or instruction of the Holder Representative shall constitute a decision of the Sellers and shall be final, binding and conclusive upon the Sellers. Biota shall have the right to rely in good faith upon an Instrument received from Holder Representative and to act in accordance with the Instrument without independent investigation. Any notice or communication given or received by, and any decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of, the Holder Representative that is within the scope of the Holder Representative’s authority under Section 11.5 shall constitute a notice or communication to or by, or a decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of all the Sellers and shall be final, binding and conclusive upon each such Seller.

(d) No Liability of Holder Representative or Biota. Neither the Holder Representative, nor any of the directors, officers, agents or employees of the Holder Representative, if applicable, shall be liable to any Seller or any other Person for any error of judgment, or any action taken, suffered or omitted to be taken, under this Agreement, except in the case of the Holder Representative’s fraud, gross negligence or willful misconduct. The Holder Representative may consult with legal counsel, independent public accountants and other experts selected by the Holder Representative and shall not be liable to any Seller for any action taken or omitted to be taken in good faith in accordance with the advice of such counsel, accountants or experts. As to any matters not expressly provided for in this Agreement, the Holder Representative shall not be required to exercise any discretion or take any action. Neither Biota, nor Anaconda nor any of their Affiliates shall have any Liability to any of the Sellers or otherwise arising out of the acts or omissions of the Holder Representative or any disputes among the Sellers or between the Sellers and the Holder Representative. Biota may rely entirely on its dealings with, and notices to and from, the Holder Representative to satisfy any obligations it may have under this Agreement or otherwise to the Sellers.

(e) Indemnity; Costs and Expenses. Each Seller shall, severally and not jointly, in proportion to the portion of the Closing Date Cash Consideration then previously received by such Sellers (or if no portion of the Closing Date Cash Consideration has been paid, in proportion to the portion of the Closing Date Cash Consideration to which such Seller is entitled), indemnify, hold harmless and defend the Holder Representative (and its directors, officers, employees, shareholders, agent and representatives) against any Damages incurred without fraud, gross negligence or willful misconduct by the Holder Representative and arising out of or in connection with the acceptance, performance or administration of the Holder Representative’s duties under this Agreement. Any Damages (including costs of defending claims prior to the final adjudication or settlement of such claims) incurred by the Holder Representative in connection with the acceptance, performance and administration of its duties as the Holder Representative pursuant to this Agreement (including the hiring of legal counsel, accountants or auditors and other advisors pursuant to the terms of this Agreement, but excluding any of the foregoing arising out of the Holder Representative’s fraud, gross negligence or willful misconduct) and all fees payable hereunder to the Holder Representative by the Sellers (“Holder Representative’s Costs”) shall be paid as follows: (i) first by recourse to the Holder Representative’s Fund, if any; and (ii) if such amounts are insufficient to pay such Holder Representative’s Costs, then by recourse directly to the Sellers (in proportion to the portion of the Closing Date Cash Consideration then previously received by each such Seller (or if no portion of the Closing Date Cash Consideration has been paid, in proportion to the portion of the Closing Date Cash Consideration to which such Seller is entitled).

(f) Holder Representative’s Fund. At the Closing, the Paying Agent may deposit with the Holder Representative an amount to be determined in the reasonable discretion of the Holder Representative, which shall be held by the Holder Representative in trust solely for the purpose of paying the expenses, if any, incurred by the Holder Representative in connection with the transactions contemplated by this Agreement (such fund created by the provision of such amount, the “Holder Representative’s Fund”). As soon as reasonably determined by the Holder Representative that the Holder Representative’s Fund is no longer required to be withheld, the Holder Representative shall distribute the remaining Holder Representative’s Fund (if any) to the Sellers, in accordance with the Closing Date Allocation Schedule. Biota shall have no obligation whatsoever with respect to the Holder Representative’s Fund, if any, and Biota shall not have Liability for the manner in which the Holder Representative administers the Holder Representative’s Fund, or for causing or ensuring that all or any portion of the Holder Representative’s Fund is ultimately paid or distributed to the Sellers.

Section 11.6. Counterparts; Electronic Delivery of Signatures. This Agreement may be executed (including by facsimile or by email of a .pdf attachment) in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument, it being understood that all Parties need not sign the same counterpart. In the event that any signature is delivered by facsimile or by email of a .pdf attachment, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or .pdf signature page were an original thereof.

Section 11.7. Severability. If any term or other provision of this Agreement is deemed or held to be invalid, illegal, or unenforceable in any respect, all other terms or provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the Agreement is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal, or unenforceable in any respect, the parties hereto shall 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. If it is ever held that any restriction hereunder is too broad to permit enforcement of such restriction to its fullest extent, each party agrees that a court of competent jurisdiction may enforce such restriction to the maximum extent permitted by Law, and each party hereby consents and agrees that such scope may be judicially modified accordingly in any proceeding brought to enforce such restriction.

Section 11.8. Third Party Beneficiaries. Other than as provided in Section 7.6 and ARTICLE IX, nothing expressed or referred to in this Agreement will be construed to give any Person other than the Parties to this Agreement (and their successors and permitted assigns) any legal or equitable right, remedy, or claim under or with respect to this Agreement or any provision of this Agreement.

Section 11.9. No Strict Construction. The Parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any of the provisions of this Agreement.

Section 11.10. Jurisdiction; Venue; Service of Process. Except as otherwise provided in Section 11.12, and except with disputes related to any dispute related to the Sellers’ obligation to indemnify Biota for Transaction Expenses and Closing Date Indebtedness pursuant to Section 9.2(a) (which such disputes shall be settled by an accountant appointed by Biota and the Holder Representative), the sole jurisdiction, venue and dispute resolution procedure for all disputes, controversies or claims (whether in contract, tort or otherwise) arising out of, relating to or otherwise by virtue of this Agreement, breach of this Agreement or the transactions contemplated by this Agreement shall be the United States District Court for the Southern District of New York, and the parties to this Agreement hereby consent to the jurisdiction of such court and waive any objection to the venue of such Proceeding. Process may be served upon each party in the manner specified in Section 11.2 and each party irrevocably waives and covenants not to assert or plead any objection which it might otherwise have to such jurisdiction, or to such manner of service of process.

Section 11.11. WAIVER OF JURY TRIAL. EACH PARTY HERETO ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES AND, THEREFORE, EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY HERETO CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE OF ANY OTHER PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF SUCH PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER, (B) EACH SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) EACH SUCH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (D) EACH SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 11.11.

Section 11.12. Injunctive Relief; Specific Performance. The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement, including the restrictive covenants contained in Section 7.6, were not performed in accordance with their specific terms or were otherwise breached, and that money damages or legal remedies would not be an adequate remedy for any such damages. Therefore, it is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent or restrain any breach or threatened breach of this Agreement, including Section 7.6, by any other Party and to enforce specifically the terms and provisions of this Agreement, including Section 7.6, to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of any other Party in any court of competent jurisdiction, in addition to any and all other rights and remedies at law or in equity. Each of the Parties hereto hereby waives (i) the defense that monetary damages would be an adequate remedy in any action for specific performance or any other form of equitable relief and (ii) any requirement under any Law to post a bond or any other security as a prerequisite to obtaining equitable relief.

Section 11.13. Headings. The descriptive headings used in this Agreement have been inserted for convenience of reference only, and are not intended to describe, interpret, define or limit the scope, extent or intent of this Agreement or any provision hereof.
