(b) Authorization and Power. The Buyer has the requisite power and authority to enter into and perform this Agreement, to subscribe for the New Shares and to purchase the Shares being sold to it hereunder. If Buyer is an entity, the execution, delivery and performance of this Agreement and the consummation by it of the transactions contemplated hereby have been duly authorized by all necessary corporate, limited liability company or partnership action, and no further consent or authorization of the Buyer or its board of directors, stockholders, partners or similar body, as the case may be, is required. This Agreement has been duly authorized, executed and delivered by the Buyer and constitute, or shall constitute when executed and delivered, valid and binding obligations of the Buyer enforceable against the Buyer in accordance with the terms thereof, except as such enforceability may be limited by general principles of equity or applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws relating to, or affecting generally, the enforcement of applicable creditors’ rights and remedies.

(c) No Public Sale or Distribution. The Buyer is acquiring the Shares for its own account and not with a view towards, or for resale in connection with, the public sale or distribution thereof, except pursuant to sales registered or exempted under the Securities Act; provided, however, that by making the representations herein, the Buyer does not agree to hold any of the Shares for any minimum or other specific term and reserves the right to dispose of all or any part of the Shares at any time in accordance with or pursuant to a registration statement or an exemption under the Securities Act and pursuant to the applicable terms of this Agreement. The Buyer is acquiring the Shares hereunder in the ordinary course of its business. The Buyer does not presently have any agreement or understanding, directly or indirectly, with any Person (as defined below) to distribute any of the Shares. As used in this Agreement, “Person” means an individual, a limited liability company, a partnership, a joint venture, a corporation, a trust, an unincorporated organization and a government or any department or agency thereof.

(d) Buyer Status. At the time the Buyer was offered the Shares, it was, and as of the date hereof it is an “accredited investor” as defined in Rule 501 under the Securities Act. The Buyer is not required to be registered as a broker-dealer under Section 15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the Buyer is not a broker-dealer, nor an affiliate of a broker-dealer.

(e) Reliance on Exemptions. The Buyer understands that the Shares are being offered and sold to it in reliance on specific exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and the Buyer’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of the Buyer set forth in this Agreement in order to determine the availability of such exemptions and the eligibility of the Buyer to acquire the Shares. The Buyer understands that the Shares therefore cannot be resold unless they are registered under the Securities Act or disposed of pursuant to a valid exemption from the registration requirements of the Securities Act. In this connection, the Buyer represents that it is familiar with Rule 144 or Rule 144A promulgated under the Securities Act (or a successor rule thereto) (collectively, “Rule 144”), and understands the resale limitations imposed thereby and by the Securities Act.

(f) Purchase Entirely for Own Account. This Agreement is made with the Buyer in reliance upon the Buyer’s representation to the Company, which by the Buyer’s execution of this Agreement the Buyer hereby confirms, that the Shares to be received by the Buyer will be acquired in the ordinary course of its business and for investment for the Buyer’s own account, not as a nominee or agent, and not with a view to the distribution of any part thereof, and that the Buyer has no present intention of selling, granting any participation in, or otherwise distributing the same. By executing this Agreement, the Buyer further represents that the Buyer does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participations to such person or to any third person, with respect to any of the Shares. By executing this Agreement, the Buyer further represents that the Buyer will not, directly or indirectly, offer, sell, pledge, transfer or otherwise dispose of (or solicit any offers to buy, purchase or otherwise acquire or take a pledge of) any of the Shares except in compliance with the Securities Act and applicable state securities laws and the respective rules and regulations promulgated thereunder.

(g) Information. The Buyer acknowledges that it and its advisors, if any, had adequate time to review the information and disclosures publicly available or made available to the Buyer prior to making its decision to purchase the Shares. The Buyer further acknowledges that any such information consisting of financial estimates, projected financial information and other forward-looking information provided by the Company or its affiliates or representatives is based on a number of assumptions and estimates that are inherently subject to significant business, economic and competitive risks, uncertainties and contingencies which are beyond the control of the Company, and that it is understood that such projections, as to future events, are not to be viewed as facts, that actual results during the period or periods covered by any such projections may differ significantly from the projected results and that such difference may be material and that such projections are not a guarantee of financial performance. The Buyer has sufficient knowledge and experience in investing in companies similar to the Company so as to be able to evaluate the risks and merits of its investment in the Company. The Buyer and its advisors, if any, have been afforded a full opportunity to ask questions of and receive answers from the Company or any person or persons acting on behalf of the Company regarding the terms and conditions

of the offering of the Shares and the merits and risks of investing in the Shares. Neither such inquiries nor any other due diligence investigations conducted by the Buyer or its advisors, if any, or its representatives shall modify, amend or affect the Buyer’s right to rely on the Company’s representations and warranties contained herein and the truth, accuracy, and completeness thereof. The Buyer understands that its investment in the Shares involves a high degree of risk and warrants that it is able to bear the economic risk and complete loss of such investment. The Buyer acknowledges that there may be certain consequences under U.S. federal, state and local income tax laws, foreign tax laws and other tax laws resulting from an investment in the Shares and has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Shares. If other than an individual, the Buyer also represents it has not been organized for the purpose of acquiring the Shares.

(h) No Governmental Review.

(i) Transfer or Resale. The Buyer understands that: (i) the Shares have not been and are not being registered under the Securities Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (A) subsequently registered thereunder, (B) the Buyer shall have delivered to the Company an opinion of counsel, in a form reasonably acceptable to the Company, to the effect that such Shares to be sold, assigned or transferred may be sold, assigned or transferred pursuant to an exemption from such registration, or (C) the Buyer provides the Company with reasonable assurance that such Shares can be sold, assigned or transferred pursuant to Rule 144, (ii) any sale of the Shares made in reliance on Rule 144 may be made only in accordance with the terms of Rule 144 and further, if Rule 144 is not applicable, any resale of the Shares under circumstances in which the seller (or the Person through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the Securities Act) may require compliance with some other exemption under the Securities Act or the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) thereunder, and (iii) neither the Company nor any other Person is under any obligation to register the Shares under the Securities Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder.

(j) Legends. The Buyer understands that the book-entry notation with the Transfer Agent or other instruments representing the Shares, if any, except as set forth below, shall bear any legend as required by the applicable “blue sky” Shares laws, rules and regulations of any state and a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of such share certificates):

The Company acknowledges and agrees that the Buyer may from time to time pledge pursuant to a bona fide margin agreement with a registered broker-dealer or grant a security interest in some or all of the Shares to a financial institution that is an “accredited investor” as defined in Rule 501(a) under the Securities

Act and, if required under the terms of such arrangement, the Buyer may transfer pledged or secured Shares to the pledgees or secured parties, subject to such transferee’s acknowledgement that the Shares are unregistered and subject to the transfer restrictions set forth therein and herein. Such a pledge or transfer would not be subject to approval of the Company and no legal opinion of legal counsel of the pledgee, secured party or pledgor shall be required in connection therewith. Further, no notice shall be required of such pledge.

(k) Legend Removal. The legend set forth above shall be removed and the Company shall deliver or cause to be delivered Shares to such holder by electronic delivery at the applicable balance account at The Depository Trust Company (“DTC”) or Computershare Trust Company, N.A., the current transfer agent of the Company and any successor transfer agent of the Company (the “Transfer Agent”), as applicable, and at the Buyer’s election so long as the Buyer is not an affiliate of the Company, if, unless otherwise required by state securities laws, (i) such Shares are registered for resale under the Securities Act, (ii) in connection with a sale, assignment or other transfer, such holder provides the Company with an opinion of a law firm reasonably acceptable to the Company, in a form reasonably acceptable to the Company, to the effect that such sale, assignment or transfer of the Shares may be made without registration under the applicable requirements of the Securities Act, or (iii) such holder provides the Company with reasonable assurance that the Shares can be sold, assigned or transferred pursuant to Rule 144. The Company shall cause its counsel to issue a legal opinion to the Transfer Agent promptly after the date on which the legend is to be removed pursuant to this Section 2(k) if required by the Transfer Agent or requested by the Buyer to effect the removal of the legend hereunder pursuant to the immediately preceding sentence.

(n) No General Solicitation and Advertising. The Buyer represents and acknowledges that it has not been solicited to offer to purchase or to purchase any Shares by means of any advertisement, article, notice or other communication regarding the Shares published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or any other general solicitation or advertising.

(q) Financial Advisors. In connection with the issue and purchase of the Shares, SVB Securities LLC, ▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. and LifeSci Capital LLC (each an “Advisor” and, collectively, the “Advisors”) have not acted as the Buyer’s financial advisor or fiduciary. The Buyer acknowledges that the Advisors assume no responsibility for independent verification of, or the accuracy or completeness of, the information supplied by the Company to the Buyer. The Buyer hereby further acknowledges and agrees that (i) each of the Advisors is acting solely as advisor to the Company in connection with the transactions contemplated hereby and is not acting as an underwriter, initial purchaser, dealer or in any other such capacity for the Buyer, the Company or any other person or entity in connection with the transactions contemplated hereby, (ii) the Advisors have not made and will not make any representation or warranty, whether express or implied, of any kind or character and have not provided any advice or recommendation in connection with the transactions contemplated hereby, and (iii) the Advisors will have no responsibility with respect to (A) any representations, warranties or agreements made by any person or entity under or in connection with the transactions contemplated hereby or any of the documents furnished pursuant thereto or in connection therewith, or the execution, legality, validity or enforceability (with respect to any person) of any thereof, or (B) the financial condition, business, or any other matter concerning the Company or the transactions contemplated hereby. To the extent permitted by applicable law, the Buyer agrees that it shall not seek redress from the Advisors or any of their or their respective affiliates’ control persons, officers, directors or employees for all or part of any loss or losses the Buyer may suffer in respect of this Agreement or its investment, and neither the Advisors nor any of their or their respective affiliates’ control persons, officers, directors or employees shall have any liability to Buyer for, anything which any of them may do or refrain from doing in connection with this Agreement.

Notwithstanding the foregoing, if the Buyer is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of the Buyer’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of the Buyer’s assets, the representation set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Shares covered by this Agreement.

As of their respective filing dates, the SEC Documents complied in all material respects with the requirements of the Exchange Act applicable to the SEC Documents, and none of the SEC Documents, at the time they were filed with the SEC and as of the date hereof, contained or contain any untrue statement of a material fact or omitted or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. As of their respective filing dates, the financial statements of the Company included in the SEC Documents complied as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto as in effect as of the time of filing. Such financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (the “IASB”) applied on a consistent basis throughout the periods covered thereby (except (i) as may be otherwise indicated in such financial statements or the notes thereto or (ii) in the case of unaudited interim statements, to the extent they may exclude footnotes or may be condensed or summary statements) and fairly present in all material respects the consolidated financial position of the Company as of the dates thereof and the results of its operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal year-end audit adjustments). No other information provided by or on behalf of the Company to the Buyer which is not included in the SEC Documents contains any untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstance under which they are or were made not misleading. The Company has never been an issuer subject to Rule 144(i) under the Securities Act.

(oo) Absence of Certain Changes. Since the date of the Company’s last filing with the SEC pursuant to the reporting requirements of the Exchange Act, except as described on Schedule 3(oo), there has not been:

(i) any change in the consolidated assets, liabilities, financial condition or operating results of the Company or its Subsidiaries from that reflected in the financial statements included in the Company’s Annual Report on Form 20-F, filed on April 7, 2022, except for changes in the ordinary course of business which have not had and could not reasonably be expected to have a Material Adverse Effect, individually or in the aggregate;

(ii) any declaration or payment of any dividend, or any authorization or payment of any distribution, on any of the shares of the Company, or any redemption or repurchase of any Shares of the Company;

(iii) any material damage, destruction or loss, whether or not covered by insurance to any assets or properties of the Company or its Subsidiaries;

(v) any satisfaction or discharge of any lien, claim or encumbrance or payment of any obligation by the Company or a Subsidiary, except in the ordinary course of business and which is not material to the assets, properties, financial condition, operating results or business of the Company and its Subsidiaries taken as a whole (as such business is presently conducted and as it is proposed to be conducted);

(vi) any change or amendment to the Company’s articles of association or organizational regulations, or material change to, or waiver of any material right under, any Material Contract (as defined below) or arrangement by which the Company or any Subsidiary is bound or to which any of their respective assets or properties is subject;

(vii) any material labor difficulties or labor union organizing activities with respect to employees of the Company or any Subsidiary;

(viii) any material transaction entered into by the Company or a Subsidiary other than in the ordinary course of business;

(ix) the loss of the services of any key employee, or material change in the composition or duties of the senior management of the Company or any Subsidiary; or

(x) any other event or condition of any character that has had or could reasonably be expected to have a Material Adverse Effect.

“Material Contract” means any contract, instrument or other agreement to which the Company or any Subsidiary is a party or by which it is bound which is material to the business of the Company and its Subsidiaries, taken as a whole, including those that have been filed or were required to have been filed as an exhibit to the SEC Filings pursuant to Item 601(b)(4) or Item 601(b)(10) of Regulation S-K.

(pp) No Undisclosed Events, Liabilities, Developments or Circumstances. No event, liability, development or circumstance has occurred or exists, or is contemplated to occur, with respect to the Company or its Subsidiaries or their respective business, properties, prospects, operations or financial condition, that would be required to be disclosed by the Company under applicable Shares laws in its reports under Section 13(a) or 15(d) of the Exchange Act and which has not been publicly announced.

(qq) Acknowledgement Regarding Buyer’s Trading Activity. Anything in this Agreement or elsewhere herein to the contrary notwithstanding, but subject to compliance by the Buyer with applicable law, it is understood and acknowledged by the Company (i) that the Buyer has not been asked by the Company or its Subsidiaries to agree, nor has the Buyer agreed with the Company or its Subsidiaries, to desist from purchasing or selling, long and/or short, Shares of the Company, or “derivative” Shares based on Shares issued by the Company or to hold the Shares for any specified term, (ii) that past or future open market or other transactions by the Buyer, including, without limitation, short sales or “derivative” transactions, before or after the closing of this or future private placement transactions, may negatively impact the market price of the Company’s publicly-traded ordinary shares, (iii) that the Buyer, and counter parties in “derivative” transactions to which any the Buyer is a party, directly or indirectly, presently may have a “short” position in the Ordinary Shares, and (iv) that the Buyer shall not be deemed to have any affiliation with or control over any arm’s length counter-party in any “derivative” transaction. The Company further understands and acknowledges that, subject to compliance by the Buyer with applicable law, (A) one or more Buyers may engage in hedging and/or trading activities at various times during the period that the Shares are outstanding and (B) such hedging and/or trading activities (if any) could reduce the value of the existing shareholders’ equity interests in the Company at and after the time that the hedging and/or trading activities are being conducted. The Company acknowledges that such aforementioned hedging activities do not constitute a breach of this Agreement.

(rr) No Overindebtedness. Neither the Company nor its Swiss subsidiaries are overindebted, or suffering from capital loss within the meaning of article 725 of the Swiss Code of Obligations.

4. COVENANTS

(a) Blue Sky. The Company, on or before the Closing Date, shall take such action as the Company shall reasonably determine is necessary, if any, in order to obtain an exemption for or to qualify the Shares for sale to the Buyer at the Closing pursuant to this Agreement under applicable securities or “blue sky” laws of the states of the United States (or to obtain an exemption from such qualification), and shall provide evidence of any such action so taken to the Buyer on or prior to the Closing Date. The Company shall make all filings and reports relating to the offer and sale of the Shares required under applicable securities or “blue sky” laws of the states of the United States following the Closing Date.

(b) Reporting Status; Public Information. Until the Buyer no longer owns any Shares, the Company shall timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed with the SEC pursuant to the Exchange Act, and the Company shall use commercially reasonable efforts not to terminate its status as an issuer required to file reports under the Exchange Act even if the Exchange Act would otherwise permit such termination.

(c) Use of Proceeds. The Company will use the net proceeds from the issuance and sale of the Shares for general corporate purposes, including the development of its clinical and pre-clinical candidates and preparation for the commercialization of its lead clinical candidate, and not for (i) the repayment of any outstanding Indebtedness of the Company or any of its Subsidiaries or (ii) redemption or repurchase of any of its or its Subsidiaries’ equity securities. The Buyer acknowledges that the Company has agreed under a letter agreement with the Advisors to pay these financial advisors certain fees in respect of the issuance and sale of the Shares to the Buyer.

(d) Listing.

(e) Fees. Each party hereto shall bear its own expenses in connection with the sale of the Shares to the Buyer.

(f) Disclosure of Transactions and Other Material Information. The Company may, at its discretion, issue a press release on or after the date of this Agreement. By 5:30 p.m., New York City time, on the Closing Date, the Company shall make commercially reasonable efforts to file a Report of Foreign Private Issuer on Form 6-K describing the terms of the transactions contemplated by this Agreement in the form required by the Exchange Act (the “Filing”). From and after the filing of the Filing with the SEC, the Buyer shall not be in possession of any material, nonpublic information received from the Company, any of its Subsidiaries or any of their respective officers, directors, employees or agents, that is not disclosed in the Filing, unless prior thereto the Buyer has consented to the receipt of such information and agreed with the Company to keep such information confidential. In addition, effective upon the issuance of the Filing, the Company acknowledges and agrees that any and all confidentiality or similar obligations under any agreement, whether written or oral, between the Company, any of its Subsidiaries or any of their respective officers, directors or employees, on the one hand, and the Buyer, on the other hand, shall terminate. The Company shall not, and shall cause each of its Subsidiaries and its and each of their respective officers, directors, employees and agents, not to, provide the Buyer with any material, nonpublic information regarding the Company or any of its Subsidiaries from and after the filing of the Filing with the SEC without the express written consent of the Buyer. If the Buyer has, or believes it has, received any such material, nonpublic information regarding the Company or any of its Subsidiaries to which it has not consented to in writing, it shall provide the Company with written notice thereof. Neither the Company, its Subsidiaries nor the Buyer shall issue any press releases or any other public statements with respect to the transactions contemplated hereby, other than a subsequent Report of Foreign Private Issuer on Form 6-K filed on the date of this Agreement that includes this Agreement as an exhibit to such Filing with the SEC; provided, however, that the Company shall be entitled, without the prior approval of the Buyer, to make any press release or other public disclosure with respect to such transactions (i) in substantial conformity with the Filing and contemporaneously therewith and (ii) as is required by applicable law and regulations. Without the prior written consent of the Buyer, neither the Company nor any of its Subsidiaries or affiliates shall disclose the name of the Buyer in any filing, announcement, release or otherwise, unless such disclosure is required by law, regulation or the Principal Market. To the extent that the Company delivers any material, non-public information regarding the Company to the Buyer (i) without the Buyer’s consent, absent an agreement as to confidentiality with respect to such information, or (ii) directly or indirectly, to the Buyer in relation to its Board Designee and Board Observer (each as defined below) rights, the Company hereby covenants and agrees that the Buyer shall not have any duty of confidentiality to Company, any of its Subsidiaries, or any of their respective officers, directors, agents or employees, or a duty to the Company, and of its Subsidiaries or any of their respective officers, directors, agents or employees not to trade on the basis of, such material, non-public information, provided that the Buyer shall remain subject to applicable law. The Company understands and confirms that the Buyer shall be relying on the foregoing covenant in effecting transactions in Shares of the Company.

(g) Conduct of Business. The business of the Company and its Subsidiaries shall not be conducted in violation of any law, ordinance or regulation of any governmental entity, except where such violations would not result, either individually or in the aggregate, in a Material Adverse Effect.

(h) Board Appointment.

(i) As of the Closing Date, the Buyer shall have the right (but not the obligation) to nominate one (1) person (the “Board Designee”) to the board of directors of the Company (the “Board”), to be proposed by the Board for election at a shareholders’ meeting of the Company to be held prior to the end of 2022.

(ii) As of the Closing Date, for the interim period between the Closing Date and the potential election of the proposed Board Designee by the shareholders’ meeting of the Company and in case the shareholders’ meeting of the Company does not vote in favor of electing the Board Designee, the Buyer shall have the right (but not the obligation) to designate one (1) individual as a Board observer (the “Board Observer”). The Board Observer shall have the same rights as a Board member except for the Board voting rights and committee roles. Subject to executing a customary confidentiality agreement as reasonably required by the Company, the Board Observer shall be allowed to attend all Board meetings as an equal insider, including the executive session, and will be reimbursed for costs

related to hotels, flights etc., subject to typical carveouts required to protect the Company’s attorney-client privilege and other fiduciary obligations.

5. REGISTER; TRANSFER AGENT INSTRUCTIONS

(a) Transfer Agent Instructions. The Company represents and warrants that no instruction, other than stop transfer instructions to give effect to Section 2(i) hereof, will be given by the Company to the Transfer Agent with respect to the Shares, and that the Shares shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Agreement and the Company’s articles of association and under applicable law. If the Buyer effects a sale, assignment or transfer of the Shares in accordance with Section 2(i), the Company shall permit the transfer and shall promptly instruct its Transfer Agent to credit shares to the applicable balance accounts of such Transfer Agent in such name and in such denominations as specified by the Buyer to effect such sale, transfer or assignment.

(b) Breach. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Buyer. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this Section 5 will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 5, that the Buyer shall be entitled, in addition to all other available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required.

Neither the Company nor the Buyer shall assign this Agreement or any rights or obligations hereunder without the prior written consent of the other party, provided that the Buyer may assign some or all of its rights hereunder without the consent of the Company to one of its affiliates, in which event such affiliate shall be deemed to be the Buyer hereunder with respect to such assigned rights; further provided that such affiliate agrees in writing to be bound, with respect to the transferred Shares, by the provisions of this Agreement that apply to the “Buyer.”

(h) No Third Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except that (1) each Indemnitee shall have the right to enforce the obligations of the Company with respect to Section 9(k) below and (2) the Advisors are entitled to rely on, and shall be third party beneficiaries of, the representations and warranties of the Buyer contained in Section 2 of this Agreement and the representations and warranties of the Company as if such representations and warranties were made directly to the Advisors.

(i) Survival. Unless this Agreement is terminated under Section 8, the representations and warranties of the Company and the Buyer contained in Sections 2 and 3, and the agreements and covenants set forth in Sections 4, 8 and 9 shall survive the Closing. The Buyer shall be responsible only for its own representations, warranties, agreements and covenants hereunder.

(j) Further Assurances.

(k) Indemnification. In consideration of the Buyer’s execution and delivery of this Agreement and acquiring the Shares thereunder and in addition to all of the Company’s other obligations under this Agreement, the Company shall defend, protect, indemnify and hold harmless the Buyer and all of its stockholders, partners, members, officers, directors, employees and direct or indirect investors (collectively, the “Indemnitees”) from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and

including reasonable attorneys’ fees and disbursements (the “Indemnified Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or relating to (a) any material misrepresentation or breach of any representation or warranty made by the Company in this Agreement or any certificate delivered by the Company hereunder, (b) any breach of any covenant, agreement or obligation of the Company contained in this Agreement or any certificate delivered by the Company hereunder or (c) any cause of action, suit or claim brought or made against such Indemnitee by a third party (including for these purposes a derivative action brought on behalf of the Company) and arising out of or resulting from the execution, delivery, performance or enforcement of this Agreement or any certificate delivered by the Company hereunder, except, in each case, with respect to any Indemnified Liabilities that resulted from any Indemnitee’s gross negligence, willful misconduct or fraud or to the extent that a loss, claim, damage or liability is attributable to any Buyer’s breach of any of the representations, warranties, covenants or agreements made by the Buyer in this Agreement and provided, that the Indemnified Liability shall in any event not exceed in the aggregate amount of distributable reserves of the Company within the meaning of article 675 of the Swiss Code of Obligations.

(l) No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

(m) Remedies. The Buyer shall have all rights and remedies set forth in this Agreement. Any Person having any rights under any provision of this Agreement shall be entitled to enforce such rights specifically (without posting a bond or other security), to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in this Agreement and hereby agree to waive and not to assert in any action for specific performance of any such obligation the defense that a remedy at law would be adequate. Each party hereto agrees that it shall not have a remedy of punitive or consequential damages against the other and hereby waives any right or claim to punitive or consequential damages it may now have or may arise in the future.

(n) Payment Set Aside. To the extent that the Company makes a payment or payments to the Buyer hereunder or the Buyer enforces or exercises its rights hereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person under any law (including, without limitation, any bankruptcy law, foreign, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.
