The application shall be submitted to Maxygen at least five days before filing for Maxygen's review and comment. The ProFound Securityholders shall not submit the application without Maxygen's prior consent, which shall not be unreasonably withheld. The ProFound Shareholders, on their behalf and on behalf of the ProFound Securityholders, acknowledge and agree that they, and not ProFound, Maxygen or Holdings, shall be responsible for the accuracy of the contents of the application. (b) If: (i) all the conditions set forth in Section 9 except the -- condition set forth in Section 9.12 are satisfied, (ii) all the conditions set forth in Section 10 except the condition set forth in Section 10.7 are satisfied or are waived by ProFound or the Securityholder Representative, (iii) the Danish tax authorities deny the application referenced in Section 7.3(a) by means of a final, non-appealable written action which explains that a reason (but not necessarily the only reason) the application was denied was the Holdings Exchange, (iv) this Agreement is terminated after that denial by ProFound under Section 11.2 or Section 11.4 and (v) ProFound elects to require that Maxygen --- extend a loan to ProFound by giving Maxygen a written notice to that effect within 20 days after that termination of this Agreement, then Maxygen, in lieu ---- of purchasing the ProFound Securities, will loan US$10 million to ProFound on the terms and conditions set forth in the balance of this Section 7.3 and on other reasonable and customary terms and conditions as the parties agree. The closing and funding of that loan will occur within 20 days after ProFound gives the notice specified in clause (v) above. (c) The loan, if made, will have these principal features: The funds loaned and all repayments will be made in, and all calculations will be based upon, U.S. dollars. The loan will be secured by a first lien on all of ProFound's tangible and intangible assets, it being understood that ProFound will pay all costs (including any and all fees and Taxes) associated with putting the lien in place and it being further understood that Maxygen's lien will be junior to the lien currently held by Vaekstfonden on certain of ProFound's assets. The loan will bear interest at one-year LIBOR plus 100 basis points, with one-year LIBOR to be set for each calendar quarter or portion of each calendar quarter during which any portion of the loan is outstanding on the first Business Day of that calendar quarter based on the quotation for that day published in The Wall Street Journal. The interest rate will increase to one- --- ---- ------ ------- year LIBOR plus 600 basis points if and for so long as the loan is in default. Interest will be payable quarterly. All principal will be payable on the fifth anniversary after the loan is extended. Seventy-five percent of the loan (i.e., - - US$7.5 million of the original principal plus all accrued and unpaid interest on that principal) will be prepayable in whole or in part at the option of ProFound without penalty or premium. Any prepayments will be applied first to accrued and unpaid interest, and then to principal. In order to preserve Maxygen's conversion right set forth in Section 7.3(d), the balance of the loan (i.e., - - US$2.5 million of the original principal plus all accrued and unpaid interest on that principal) will not be prepayable, even with --- 43 penalty or premium, unless Maxygen so consents, which it shall be entitled not to do in its sole discretion. During the duration of the loan, Maxygen shall be a beneficiary of all affirmative and negative covenants that run to the benefit of any other Person or Persons that then have outstanding loans to ProFound. (d) At any time during the duration of the loan (including after its maturity date if any portion of the loan is then in default), Maxygen, at Maxygen's option exercisable by written notice to ProFound, may convert up to US$2.5 million of the principal of the loan, plus all accrued and unpaid interest on that principal, into shares of Class B ProFound Common Stock or other equity securities of ProFound having the same rights, preferences and privileges as shares of Class B ProFound Common Stock. The price per share of the securities purchased on conversion will be the lower of (i) US$68 and (ii) 70 percent of the per security price at which ProFound securities are purchased in ProFound's next round of equity financing (adjusted, if and as appropriate in the case of clause (i) and clause (ii), to reflect stock splits, stock dividends and similar events). The entitlements that accompany the securities purchased by Maxygen shall include all related contractual arrangements (such as representations, warranties, indemnities and tag-along rights) and legal opinions received by any other Person or Persons that purchased any shares of Class B ProFound Common Stock. (e) During the duration of the loan (including after its maturity date if any portion of the loan is then default), unless and until Maxygen has exercised its conversion right in full, ProFound shall give Maxygen at least ten Business Days' prior written notice of the record date for any dividend, distribution, exchange or other event or development respecting any class or series of ProFound securities. The purpose of this requirement is to inform Maxygen of entitlements that may be associated with any class or series of ProFound securities into which Maxygen might convert a portion of its loan so that Maxygen may better determine whether to exercise its conversion right. An example is a record date for an acquisition of ProFound in which ProFound securityholders would receive cash or securities of another entity for their ProFound securities. (f) If the events set forth in clauses (i) through (iv) of Section -- 7.3(b) occur but ProFound does not timely require that Maxygen loan funds to ProFound, then, if Maxygen so elects, it may purchase up to the Danish kroner ---- equivalent of US$2.5 million of ProFound securities at the next closing of an issuance of equity securities by ProFound, excluding issuances to employees under warrants, in which (unless Maxygen waives this requirement) at least the Danish kroner equivalent of another US$2.5 million of such equity securities are ------- sold to one or more Persons who are not presently ProFound Securityholders or affiliates of present ProFound Securityholders. The price per security, the class and series of such securities, and the entitlements that accompany those securities including all related contractual arrangements (such as representations, warranties, indemnities and tag-along rights) and legal opinions of which Maxygen is a 44 beneficiary shall be the same as those received by such other "independent" investors. The "Danish kroner equivalent" for purposes of this Section 7.3(f) shall be based upon the "buy" exchange rate (U.S. dollars for Danish kroner) published in The Wall Street Journal for the last Business Day before the day --- ---- ------ ------- that the securities purchase closes.

(b) Notwithstanding the foregoing, no aspect of Section 12.3(a) shall apply to any Losses or Environmental, Health, and Safety Liabilities based upon, arising out of or otherwise in respect of any fraudulent breach of any representation or warranty of ProFound or any ProFound Securityholder set forth in this Agreement or any of the agreements delivered under Section 9.9. Moreover, except as explained in the next sentence, the indemnification obligations of the ProFound Shareholders shall be joint and several whether or not Section 12.3(a) applies and whether or not, in the case of breaches of representation and warranties, those representation and warranties are set forth in Section 4 or 5, or any of the agreements delivered under Section 9.9. Notwithstanding the foregoing, the indemnification obligations of Novo Nordisk A/S shall extend beyond the Escrow Fund governed by the Escrow Agreement only to the extent of any Losses resulting from, imposed upon, or incurred or suffered by a Maxygen Indemnitee by virtue of a breach of any of Novo Nordisk A/S's representations and warranties set forth in Section 5.2 of this Agreement or any fraudulent breach of any other representation or warranty by Novo Nordisk A/S. 59 12.4 INDEMNIFICATION PROCEDURES -------------------------- (a) Notice. Whenever any third Person claim shall arise for which ------ indemnification may be sought hereunder (a "Claim"), the party entitled to indemnification (the "Maxygen Indemnitee") shall promptly give notice to the Securityholder Representative, with respect to the Claim after the receipt by the Maxygen Indemnitee of reliable information as to the facts constituting the basis for the Claim; but the failure to timely give such notice shall not relieve the Indemnitor from any obligation under this Agreement, except to the extent, if any, that the Indemnitor is materially prejudiced thereby. (b) Defense. After delivery of notice from the Maxygen Indemnitee of a ------- Claim, the Maxygen Indemnitee may elect to assume the defense of the Claim. If the Maxygen Indemnitee notifies the Securityholder Representative that the Maxygen Indemnitee is not assuming the defense of the Claim, the Securityholder Representative shall defend the Claim. Irrespective of whether the Maxygen Indemnitee or the Securityholder Representative defends the Claim, the cost and the expense of that defense shall be paid from the escrow fund established under the Escrow Agreement until that fund is exhausted. If the Maxygen Indemnitee elects to assume the defense of the Claim, the Securityholder Representative shall cooperate in all reasonable respects, at the Securityholder Representative's sole cost, risk and expense, with the Maxygen Indemnitee and its counsel in the investigation, trial, defense and any appeal arising from the matter from which the Claim arose. If the Securityholder Representative defends the Claim, the Maxygen Indemnitee shall cooperate in all reasonable respects with the Securityholder Representative and its counsel in the investigation, trial, defense and any appeal arising from the matter from which the Claim arose and shall deliver to the Securityholder Representative or its counsel copies of all pleadings and other information within the Maxygen Indemnitee's knowledge or possession reasonably requested by the Securityholder Representative or its counsel that are relevant to the defense of the subject of any such Claim. If the Securityholder Representative defends the Claims, the Securityholder Representative shall have the right to elect to settle any claim for monetary damages without the Maxygen Indemnitee's consent only if the settlement includes a complete release of the Maxygen Indemnitee. Any other settlement will be subject to the consent of the Maxygen Indemnitee. The Securityholder Representative may not admit any liability of the Maxygen Indemnitee or waive any of the Maxygen Indemnitee's rights without the Maxygen Indemnitee's prior consent. The Securityholder Representative shall not be liable for any settlement effected without its prior consent, such consent not to be unreasonably withheld. If any Claim results in a judgment or settlement consistent with the terms of this Section 12.4(b), then, subject to the rules set forth in this Section 12 that could result in indemnification "beyond" the amounts held in the Escrow Fund (see Sections 12.1(b) and 12.3(b)), such judgment or settlement shall be paid out of any remaining amounts in the Escrow Fund. 60 13. GENERAL PROVISIONS ------------------ 13.1 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 (prior to, at or after the Closing) for the purpose of carrying out or evidencing any of the transactions contemplated by this Agreement. 13.2 CONFIDENTIALITY --------------- The parties acknowledge that Maxygen and ProFound have entered into the Confidentiality Agreement, and that such agreement will survive the termination of this Agreement or the consummation of the Exchanges. Without limiting the generality of anything contained in Section 13.6 (Public Announcements), on and at all times after the Closing Date, each ProFound Shareholder shall keep confidential, and shall not use or disclose to any other Person, any non-public document or other non-public information in such ProFound Shareholders' possession that relates to the business of Maxygen, Holdings or ProFound. 13.3 SEVERABILITY ------------ In the event that any provision of this Agreement, or the application of any such provision to any Person or set of circumstances, shall be determined to be invalid, unlawful, void or unenforceable to any extent, the remainder of this Agreement, and the application of such provision to Persons or circumstances other than those as to which it is determined to be invalid, unlawful, void or unenforceable, shall not be impaired or otherwise affected and shall continue to be valid and enforceable to the fullest extent permitted by law. 13.4 EXPENSES -------- Maxygen and ProFound will bear their respective fees, costs and expenses incurred in connection with the preparation, execution, delivery and performance of this Agreement, including all fees, costs and expenses of agents, representatives, counsel and accountants. Notwithstanding the foregoing and in addition to all other remedies available at law or equity, if the Agreement is terminated pursuant to Section 11.2 or 11.4, then Maxygen and Holdings (if Maxygen's or Holdings' breach gave rise to that termination) or ProFound and the ProFound Shareholders (if ProFound's or a ProFound Securityholder's breach gave rise to that termination) shall pay the other party or parties by cashier's check or wire transfer within 10 Business Days after submission of invoices in reasonable detail all of the non-breaching party's or parties' out-of-pocket expenses incurred in connection with the transactions contemplated by this Agreement. 61 13.5 CONVEYANCE DOCUMENTS AND TAXES ------------------------------ The parties shall cooperate in the preparation, execution and filing of all returns, questionnaires, applications, or other documents regarding any real or personal property transfer or any gains, sales, use, transfer, value added, stock transfer and stamp Taxes, any transfer, recording, registration and other fees, and any similar Taxes which become payable in connection with the transactions contemplated hereby that are required or permitted to be filed, whether before, on or after the Closing, and the ProFound Securityholders shall be responsible for the payment of all such Taxes and fees. 13.6 PUBLIC ANNOUNCEMENTS -------------------- Unless required by Law, any public announcement or similar publicity with respect to this Agreement, the Closing, the Exchanges or the other transactions contemplated hereby will be issued, if at all, at such time and in such manner as Maxygen determines with the concurrence of ProFound, which concurrence shall not be unreasonably withheld or delayed by ProFound. Unless disclosure is consented to by Maxygen in advance or required by Law or disclosure has otherwise already been made, ProFound shall keep this Agreement and the transactions contemplated hereby strictly confidential and may not make any disclosure of this Agreement or such transactions to any Person other than its Representatives or employees who need to know such information to enable ProFound and the ProFound Shareholders to comply with this Agreement, provided that each such Representative or employee shall agree, for the benefit of Maxygen, to maintain the confidentiality of such information as provided in this Section 13.6. ProFound and Maxygen will consult with each other concerning the means by which ProFound's employees, customers and suppliers and other Persons having dealings with ProFound will be informed of this Agreement, the Closing, the Exchange and the other transactions contemplated hereby, and representatives of Maxygen may at its option be present for any such communication. 13.7 NOTICES ------- All notices, consents, waivers, and other communications under this Agreement must be in writing and will be deemed to have been duly given when (a) delivered by hand (with written confirmation of receipt), (b) sent by fax (with written confirmation of receipt), provided that a copy is mailed by registered mail, return receipt requested, or (c) when delivered to the address, if sent by an internationally recognized overnight delivery service (receipt requested), in each case to the appropriate addresses or fax numbers set forth below (or to such other address, Person's attention or fax number as a party may designate by notice to the other parties given in accordance with this Section 13.7): 62 (a) If to Maxygen or Holdings: ------------------------- Maxygen, Inc. 515 Galveston Drive Redwood City, California 94068 U.S.A.

Seidenwurm 13.8 ARBITRATION ----------- (a) Any dispute, controversy or claim arising out of this Agreement, the Escrow Agreement or any other Transaction Document, including the termination of any of those agreements or any alleged breach of any of those agreements, shall be finally settled by binding arbitration as set forth in this Section 13.8. Arbitration of any dispute, controversy or claim shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association by three independent, neutral arbitrators appointed in accordance with those rules. The arbitration shall be held in San Francisco, California, U.S.A. The arbitrators shall determine what discovery shall be permitted, consistent with the goal of limiting the cost and time which the parties must expend for discovery, provided that the arbitrators shall permit such discovery as they deem necessary or useful to permit an equitable and informed resolution of the dispute. Any written evidence originally in a language other than English shall be submitted in English translation accompanied by the original or a true copy thereof. (b) The decision or award rendered by the arbitrator shall be written (specifically stating the arbitrator's findings of facts, as well as the reasons upon which the arbitrator's decision is based), final and nonappealable (except for an alleged act of corruption or fraud on the part of the arbitrator) and may be entered in any court of competent jurisdiction for a judicial recognition of the decision and an order of enforcement. The parties agree that, any provision of applicable law notwithstanding, they will not request, and the arbitrator shall have no authority to award, punitive or exemplary damages against any party. Except as otherwise expressly provided in this Agreement, the costs of the arbitration, including administrative and arbitrator's fees, shall be borne 50 percent by Maxygen and Holdings (jointly and severally) and: (i) if this Agreement is terminated, 50 percent by ProFound and the ProFound Shareholders (jointly and severally) and (ii) if the Closing occurs, by the ProFound Shareholders (jointly and severally). Each party shall bear its own costs and attorneys' and witness' fees incurred in connection with the arbitration. 64 (c) A disputed performance or suspended performance pending the resolution of the arbitration must be completed within a reasonable time following the final decision of the arbitrators. The arbitrators shall be directed that any arbitration subject to this Section 13.8 shall be completed within one year from the filing of notice of a request for such arbitration. The arbitration proceedings and the decision shall not be made public without the joint consent of the parties. Each party shall maintain the confidentiality of such proceedings and decision, unless otherwise permitted by Maxygen and the Securityholder Representative. However, if advised by counsel that disclosure is necessary or appropriate under applicable law, Maxygen shall be entitled to disclose the proceedings and decision without the consent of any other party after giving notice to the Securityholder Representative. Likewise, if advised by counsel that disclosure is necessary or appropriate under applicable law, the Securityholder Representative shall be entitled to disclose the proceedings and decision without the consent of any other party after giving notice to Maxygen. (d) Except as provided in the Escrow Agreement, any decision that requires a monetary payment shall require such payment to be made in United States dollars, free of any Tax or other deduction. The parties agree that the decision shall be the sole, exclusive and binding remedy between and among them regarding any and all disputes, controversies, claims and counterclaims presented to the arbitrators. The interpretation and enforcement of this Section 13.8 shall be governed by the U.S. Federal Arbitration Act. Pending the establishment of the arbitral tribunal or pending the arbitral tribunal's determination of the merits of the controversy, either party may seek from a court of competent jurisdiction any interim or provisional relief that may be necessary to protect the rights or property of that party. 13.9 FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE; SPECIFIC --------------------------------------------------------------- PERFORMANCE ----------- No failure or delay on the part of any party hereto in the exercise of any right hereunder shall impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty, covenant or agreement herein, nor shall any single or partial exercise of any such right preclude other or further exercise thereof or of any other right. All rights and remedies existing under this Agreement are cumulative to, and not exclusive of, any rights or remedies otherwise available. The parties to this Agreement agree that, in the event of any breach or threatened breach by any party to this Agreement of any covenant, obligation or other provision set forth in this Agreement for the benefit of any other party to this Agreement, subject to Section 13.8, such other party shall be entitled (in addition to any other remedy that may be available to it) to (a) a decree or order of specific performance or mandamus to enforce the observance and performance of such covenant, obligation or other provision, and (b) an injunction restraining such breach or threatened breach. 65 13.10 ASSIGNMENTS, SUCCESSORS, AND NO THIRD-PARTY RIGHTS -------------------------------------------------- No party may assign any of its rights under this Agreement without the prior written consent of the other parties except that Maxygen may assign any of its rights, but not its obligations, under this Agreement to any direct wholly- owned Subsidiary of Maxygen. Subject to the preceding sentence, this Agreement will apply to, be binding in all respects upon, and inure to the benefit of the successors and permitted assigns of the parties and their respective heirs and personal representatives. Nothing expressed or referred to in this Agreement will be construed to give any Person other than the parties to this Agreement and the Maxygen Indemnitees any legal or equitable right, remedy or claim under or with respect to this Agreement or any provision of this Agreement. 13.11 SECTION HEADINGS, CONSTRUCTION ------------------------------ The headings of Sections in this Agreement are provided for convenience only and will not affect its construction or interpretation. In this Agreement (i) words denoting the singular include the plural and vice versa, (ii) "it" or "its" or words denoting any gender include all genders, (iii) the word "including" shall mean "including without limitation," whether or not expressed, (iv) any reference to a statute shall mean the statute and any regulations thereunder in force as of the date of this Agreement or the Closing, as applicable, unless otherwise expressly provided, (v) any reference herein to a Section, Schedule or Exhibit refers to a Section of or a Schedule or Exhibit to this Agreement, unless otherwise stated, and (vi) when calculating the period of time within or following which any act is to be done or steps taken, the date which is the reference day in calculating such period shall be excluded and if the last day of such period is not a Business Day, then the period shall end on the next day that is a Business Day. Each party acknowledges that he, she or it has been advised and represented by counsel in the negotiation, execution and delivery of this Agreement and accordingly agrees that if an ambiguity exists with respect to any provision of this Agreement, such provision shall not be construed against any party because such party or its representatives drafted such provision. 13.12 GOVERNING LAW ------------- Except as provided in Section 13.8 and except in the case of those corporate law matters which necessarily are governed by Danish law due to the fact that ProFound is incorporated and doing business in Denmark, this Agreement will be governed by the internal laws of the State of California and without regard to principles of conflict of laws. 66 13.13 COUNTERPARTS ------------ This Agreement may be executed in one or more counterparts, each of which will be deemed to be an original copy of this Agreement and all of which, when taken together, will be deemed to constitute one and the same agreement. 13.14 ENTIRE AGREEMENT AND MODIFICATION --------------------------------- This Agreement supersedes all prior agreements (other than the Confidentiality Agreement), whether written or oral, between or among the parties with respect to its subject matter and constitutes (along with the documents referred to in this Agreement) the entire agreement among the parties with respect to its subject matter. This Agreement may not be amended except by a written agreement executed by Maxygen, Holdings, ProFound and either (i) ProFound Shareholders holding a majority 67 of the shares of ProFound Common Stock just before the Closing or (ii) the Securityholder Representative. IN WITNESS WHEREOF, the parties have executed and delivered this Agreement as of the date first written above. MAXYGEN, INC. By: /s/ Russell J. Howard --------------------- Name: Russell J.
