Other than with its Affiliates, Purchaser is not a member of a “group” (as such term is used in Section 13(d) of the Exchange Act) of Persons with respect to any securities of the Company (it being understood that in no event will the Viking Purchaser or any of its Affiliates be deemed to be Affiliates of Purchaser for purposes of this Section 4.6).

(a) Investor Status; Sophisticated Purchaser. Purchaser is an “accredited investor” within the meaning of Regulation D of the Securities Act and is able to bear the risk of its investment in the Purchased Shares. Purchaser has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of the purchase of the Purchased Shares.

(b) Information. Purchaser and its Representatives have been furnished with (i) materials relating to the business, finances and operations of the Company, (ii) materials relating to the offer and sale of the Purchased Shares and (iii) materials relating to the Casdin Transaction, in each case, that have been requested by Purchaser. Purchaser and its Representatives have been afforded the opportunity to ask questions of the Company. Neither such inquiries nor any other due diligence investigations conducted at any time by Purchaser and its Representatives shall modify, amend or affect Purchaser’s right (i) to rely on the Company’s representations and warranties contained in Article III above or (ii) to indemnification or any other remedy based on, or with respect to the accuracy or inaccuracy of, or compliance with, the representations, warranties, covenants and agreements in this Agreement.

Purchaser 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 Purchased Shares.

46

(c) Legends. Purchaser understands that any certificate or book-entry position evidencing Acquired Shares will bear the restrictive legend set forth in the Certificate of Designations.

(d) Purchase Representations. Purchaser is purchasing the Purchased Shares for its own account, the account of its Affiliates, or the accounts of clients for whom Purchaser exercises discretionary investment authority (all of whom Purchaser hereby represents and warrants are “accredited investors” within the meaning of Regulation D of the Securities Act), not as a nominee or agent, and not with a view to distribution in violation of any securities Laws. Purchaser has been advised and understands that the Purchased Shares have not been registered under the Securities Act or under the “blue sky” laws of any jurisdiction and may be resold only if registered pursuant to the requirements of the Securities Act (or if eligible, pursuant to Rule 144 promulgated under the Securities Act or pursuant to another available exemption from the registration requirements of the Securities Act). Purchaser has been advised and understands that the Company, in issuing the Purchased Shares, is relying upon, among other things, the representations and warranties of Purchaser contained in this Section 4.9 in concluding that such issuance is a “private offering” and is exempt from the registration provisions of the Securities Act.

(e) Rule 144. Purchaser understands that there is no public trading market for the Purchased Shares, that none is expected to develop and that the Purchased Shares shall be held indefinitely unless and until the Purchased Shares are registered under the Securities Act or an exemption from registration is available. Purchaser has been advised of and is knowledgeable with respect to the provisions of Rule 144 promulgated under the Securities Act.

(f) Reliance by the Company. Purchaser understands that the Purchased Shares are being offered and sold in reliance on a transactional exemption from the registration requirements of federal and state securities Laws and that the Company is relying on the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings of Purchaser set forth herein in order to determine the applicability of such exemptions and the suitability of Purchaser to acquire the Purchased Shares.

4.10 Stockholder and Management Arrangements. Except for the Transaction Documents or as previously disclosed to the Company in writing, neither Purchaser nor any of its Affiliates is a party to any Contract, or has authorized, made or entered into, or committed or agreed to enter into, any formal or informal arrangements or other understandings (whether or not binding) with any stockholder, director, officer, employee or other Affiliate of the Company or any of its Subsidiaries: (a) relating to this Agreement, the Casdin Transaction or the Viking Transaction, (b) pursuant to which any holder of Company Common Stock has agreed to approve this Agreement or (c) pursuant to which any Person has agreed to provide, directly or indirectly, an equity investment to the Purchaser or the Company to finance any portion of the Transaction.

51

(c) Company Board Recommendation Change. Notwithstanding anything to the contrary set forth in this Agreement, at any time prior to obtaining the Requisite Stockholder Approval, the Company Board (or a committee thereof) may effect a Company Board Recommendation Change in response to an Intervening Event if the Company Board (or a committee thereof) determines in good faith (after consultation with its financial advisor and outside legal counsel) that the failure to do so would be inconsistent with its fiduciary duties pursuant to applicable Law; provided, that, the Company Board (or a committee thereof) shall not effect such a Company Board Recommendation Change unless:

(i) the Company has provided prior written notice to Purchaser and the Viking Purchaser at least five Business Days in advance to the effect that the Company Board (or a committee thereof) has (A) made such determination; and (B) resolved to effect a Company Board Recommendation Change pursuant to this Section 5.3(c), which notice shall specify the basis for such Company Board Recommendation Change, including a reasonably detailed description of the facts and circumstances relating to such Intervening Event and copies of all relevant documents relating thereto;

(ii) prior to effecting such Company Board Recommendation Change, the Company and its Representatives, during such five Business Day period, shall have negotiated with Purchaser, the Viking Purchaser and their respective Representatives in good faith (to the extent that Purchaser or the Viking Purchaser desires to so negotiate) to make such adjustments to the terms and conditions of this Agreement so that the Company Board (or a committee thereof) would no longer determine that the failure to make a Company Board Recommendation Change in response to such Intervening Event would be inconsistent with its fiduciary duties pursuant to applicable Law; and

(iii) at the end of such five Business Day period and taking into account any adjustments to the terms and conditions of this Agreement and the Viking Purchase Agreement, the Company Board (or a committee thereof) has determined in good faith (after consultation with its financial advisor and outside legal counsel) that the failure to make a Company Board Recommendation Change in response to such Intervening Event would continue to be inconsistent with its fiduciary duties pursuant to applicable Law.

For the avoidance of doubt, the determination by the Company Board (or a committee thereof) that an Intervening Event has occurred or the delivery by the Company of a notice contemplated by this Section 5.3(c) shall not constitute a Company Board Recommendation Change if otherwise in compliance with this Section 5.3.

52

(d) Notice. From the date hereof until the earlier to occur of the termination of this Agreement pursuant to Article VIII and the Closing, the Company shall promptly (and, in any event, within 24 hours) notify Purchaser if any offers or proposals that constitute an Acquisition Proposal are received by, any non-public information is requested from, or any discussions or negotiations are sought to be initiated or continued with, the Company or any of its Representatives. Such notice shall include a summary of the material terms and conditions of such offer, proposal, request, inquiry, discussions or negotiations, including the identity of the Person making any such offer, proposal, request or inquiry or seeking to engage in such discussions or negotiations, and a copy of any written documents in connection therewith (including any updates or amendments thereto).

(e) Certain Disclosures. Nothing in this Agreement shall prohibit the Company or the Company Board (or a committee thereof) from (i) taking and disclosing to the Company Stockholders a “stop, look and listen” communication by the Company Board (or a committee thereof) to the Company Stockholders pursuant to Rule 14d-9(f) promulgated under the Exchange Act (or any substantially similar communication); (ii) informing any Person of the existence of the provisions contained in this Section 5.3; or (iii) complying with the Company’s disclosure obligations under U.S. federal or state Law with regard to an Acquisition Proposal, it being understood that any such statement or disclosure made by the Company Board (or a committee thereof) shall be subject to the terms and conditions of this Agreement and nothing in this Section 5.3(e) shall permit the Company to make a Company Board Recommendation Change.

5.4 No Control of the Other Party’s Business. The Parties acknowledge and agree that the restrictions set forth in this Agreement are not intended to give Purchaser, on the one hand, or the Company, on the other hand, directly or indirectly, the right to control or direct the business or operations of the other at any time prior to the Closing. Prior to the Closing Date, Purchaser and the Company shall exercise, consistent with the terms, conditions and restrictions of this Agreement, complete control and supervision over their own business and operations.

In furtherance and not in limitation of the foregoing, the Company and Purchaser shall (and shall cause their respective controlling Persons, controlled Affiliates and Subsidiaries, respectively, to), subject to any restrictions under applicable Laws: (i) promptly notify the other Party of, and, if in writing, furnish the other with copies of (or, in the case of oral communications, advise the others of the contents of) any material communication received by such Person from a Governmental Authority in connection with the Casdin Transaction and the Series B-1 Conversion and permit the other Party to review and discuss in advance (and to consider in good faith any comments made by the other Party in relation to) any proposed draft notifications, formal notifications, filing, submission or other written communication (and any analyses, memoranda, white papers, presentations, correspondence or other documents submitted therewith) made in connection with the Casdin Transaction and the Series B-1 Conversion (as applicable) to a Governmental Authority; (ii) keep the other Party informed with respect to the status of any such submissions and filings to any Governmental Authority in connection with the Casdin Transaction and the Series B-1 Conversion (as applicable) and any developments, meetings or discussions with any Governmental Authority in respect thereof, including with respect to (A) the receipt of any non-action, action, clearance, consent, approval or waiver, (B) the expiration of any waiting period, (C) the commencement or proposed or threatened commencement of any investigation, litigation or administrative or judicial action or proceeding under applicable Laws, including any proceeding initiated by a private party and (D) the nature and status of any objections raised or proposed or threatened to be raised by any Governmental Authority with respect to the Casdin Transaction and the Series B-1 Conversion (as applicable); and (iii) not independently participate in any meeting, hearing, proceeding or discussions (whether in person, by telephone or otherwise) with or before any Governmental Authority in respect of the Casdin Transaction or the Series B-1 Conversion without giving the other party reasonable prior notice of such meeting or discussions and, unless prohibited by such Governmental Authority, the opportunity to attend or participate. Subject to restrictions under applicable Law, Purchaser shall not, without the prior written consent of the Company, extend or offer or agree to extend any waiting period under the HSR Act or any other Antitrust Law, or enter into any agreement with any Governmental Authority related to this Agreement, the transactions contemplated by this Agreement or the Series B-1 Conversion. However, the Company and Purchaser may each designate any non-public information provided to any Governmental Authority as restricted to “outside counsel” only and any such information shall not be shared with employees, officers or directors or their equivalents of the other Party without approval of the Party providing the non-public information; provided, that each of the Company and Purchaser may redact any valuation and related information before sharing any information provided to any Governmental Authority with the other Party on an “outside counsel” only basis, and that the Company and Purchaser shall not in any event be required to share information that benefits from legal privilege with the other Party, even on an “outside counsel” only basis, where this would cause such information to cease to benefit from legal privilege.

(c) Other Action. Purchaser shall not, directly or indirectly (whether by merger, consolidation or otherwise), acquire (or agree to acquire) any business, corporation partnership, association or other business organization or division or part thereof, or any securities or collection of assets, if doing so would reasonably be expected to prevent or materially delay the consummation of the Casdin Transaction.

55

(d) Limitations on Action. Notwithstanding anything to the contrary in this Agreement, nothing in this Agreement, including this Section 6.2, shall require or obligate Purchaser or any of its Affiliates to agree, propose, commit to, or effect, or otherwise be required, by consent decree, hold separate, or otherwise, any sale, divestiture, hold separate, or any other action otherwise limiting the freedom of action in any respect with respect to any businesses, products, rights, services, licenses, assets, or interest therein, of Purchaser or any Affiliate.

6.3 Proxy Statement.

(a) Proxy Statement. As promptly as practical following the date of this Agreement, the Company (with the assistance and cooperation of Purchaser as reasonably requested by the Company) shall prepare and file with the SEC a preliminary proxy statement (as amended or supplemented, the “Proxy Statement”) relating to the Company Stockholder Meeting, and the Company shall use its reasonable best efforts to make such filing within 15 days of the date of this Agreement. Subject to Section 5.3(c), the Company shall include the Company Board Recommendation in the Proxy Statement. Prior to the filing of the Proxy Statement (or any amendment or supplement thereto), or any dissemination thereof to the Company Stockholders, or responding to any comments from the SEC with respect thereto, the Company shall provide Purchaser and its counsel with a reasonable opportunity to review and to comment on such document or response, which comments the Company shall consider in good faith. None of the information supplied or to be supplied by or on behalf of the Company or Purchaser for inclusion or incorporation by reference in the Proxy Statement, as of the date it or any amendment or supplement is mailed to the Company Stockholders and at the time of the Company Stockholder Meeting, shall contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances in which they are made, not misleading.

(b) Furnishing Information. The Company, on the one hand, and Purchaser, on the other hand, shall furnish all information concerning it and its Affiliates, if applicable, as the other Party may reasonably request in connection with the preparation and filing with the SEC of the Proxy Statement. If at any time prior to the Company Stockholder Meeting any information relating to the Company, Purchaser or any of their respective Affiliates should be discovered by the Company, on the one hand, or Purchaser, on the other hand, that should be set forth in an amendment or supplement to the Proxy Statement so that such filing would not include any misstatement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, then the Party that discovers such information shall promptly notify the other, and an appropriate amendment or supplement to such filing describing such information shall be promptly prepared and filed with the SEC by the appropriate Party and, to the extent required by applicable law or the SEC or its staff, disseminated to the Company Stockholders.

56

(c) Consultation Prior to Certain Communications. The Company and its Affiliates, on the one hand, and Purchaser and its Affiliates, on the other hand, shall not communicate in writing with the SEC or its staff with respect to the Proxy Statement without first providing the other Party a reasonable opportunity to review and comment on such written communication, and each Party shall give due consideration to all reasonable additions, deletions or changes suggested thereto by the other Parties or their respective counsel.

(d) Notices. The Company, on the one hand, and Purchaser, on the other hand, shall advise the other, promptly after it receives notice thereof, of (i) any receipt of a request by the SEC or its staff for any amendment or revisions to the Proxy Statement, (ii) any receipt of comments from the SEC or its staff on the Proxy Statement; or (iii) any receipt of a request by the SEC or its staff for additional information in connection therewith.

(e) Dissemination of Proxy Statement. Subject to applicable Law, the Company shall use its reasonable best efforts to cause the definitive Proxy Statement to be disseminated to the Company Stockholders as promptly as reasonably practicable following the filing thereof with the SEC and confirmation from the SEC that it will not review, or that it has completed its review of, the Proxy Statement.

6.4 Company Stockholder Meeting.

(a) Call of Company Stockholder Meeting. Within 10 calendar days after the date of this Agreement (and thereafter as reasonably determined by the Company in consultation with Purchaser), the Company shall conduct a “broker search” in accordance with Rule 14a-13 of the Exchange Act for a record date for the Company Stockholder Meeting that is 20 Business Days after the date of such “broker search.” Following the clearance of the Proxy Statement by the SEC, the Company shall duly call and hold a meeting of its stockholders (the “Company Stockholder Meeting”) as promptly as reasonably practicable (taking into account the time necessary to solicit proxies for the approval of the Transactions and the Certificate of Amendment) following the mailing of the Proxy Statement to the Company Stockholders, which mailing shall be initiated in accordance with Section 6.3(e). Unless there has been a Company Board Recommendation Change in accordance with Section 5.3(c), the Company shall use its reasonable best efforts to solicit proxies to obtain the Requisite Stockholder Approval.

(b) Adjournment of Company Stockholder Meeting. Notwithstanding anything to the contrary in this Agreement, nothing shall prevent the Company from postponing or adjourning the Company Stockholder Meeting: (i) to allow additional solicitation of votes in order to obtain the Requisite Stockholder Approval; (ii) if there are holders of an insufficient number of shares of Company Common Stock present or represented by proxy at the Company Stockholder Meeting to constitute a quorum at the Company Stockholder Meeting; (iii) if the Company is required to postpone or adjourn the Company Stockholder Meeting by applicable Law or receives a request from the SEC or its staff to do so; or (iv) if the Company Board (or a committee thereof) has determined in good faith (after consultation with outside legal counsel) that it is required under applicable Law to postpone or adjourn the Company Stockholder Meeting in order to give the Company Stockholders sufficient time to evaluate any information or disclosure that the Company has sent to the Company Stockholders or otherwise made available to the Company Stockholders. Notwithstanding the foregoing, (A) the Company shall not, without the prior written consent of Purchaser, postpone the Company Stockholder Meeting for more than 20 Business Days in the aggregate and (B) the Company shall, at the request of Purchaser, to the extent permitted by applicable Law, adjourn the Company Stockholder Meeting to a date specified jointly by Purchaser

57

and the Company (acting in good faith and taking into account the time necessary to solicit proxies) if a quorum is absent at the Company Stockholder Meeting or if the Company has not received proxies representing a sufficient number of shares of Company Common Stock to obtain the Requisite Stockholder Approval (it being understood that Purchaser shall not be able to cause the Company to adjourn the Company Stockholders Meeting to a date that is less than 10 Business Days before the Termination Date).

(c) Meeting Obligation. For the avoidance of doubt, the Company’s obligations pursuant to this Section 6.4 shall not be affected by (i) the commencement, public proposal, public disclosure or communication to the Company of an Acquisition Proposal or (ii) any Company Board Recommendation Change.

6.5 Anti-Takeover Laws. The Company and Purchaser shall (a) take all actions within their power to ensure that no “control share acquisition,” “fair price,” “moratorium,” “business combination” or other state anti-takeover Law (including Section 203 of the DGCL), statute or similar statute or regulation is or becomes applicable to the Transactions or any other transactions contemplated by this Agreement or the other Transaction Documents and (b) if any “control share acquisition,” “fair price,” “moratorium,” “business combination” or other state anti-takeover Law (including Section 203 of the DGCL), statute or similar statute or regulation becomes applicable to the Transactions or any other transactions contemplated by this Agreement or the other Transaction Documents, take all actions within their power to ensure that the Transactions may be consummated as promptly as reasonably practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation on the Transactions.

6.6 Use of Proceeds. The Company shall use the proceeds of the PGEF II Purchase Price and the PMF Purchase Price paid by Purchaser, together with the proceeds of the purchase price paid by the Viking Purchaser pursuant to the Viking Purchase Agreement to pay the Company’s expenses related to the Casdin Transaction, the Viking Transaction, for working capital, for mergers and acquisitions and for general corporate purposes.

6.7 Access. At all times during the period commencing with the execution and delivery of this Agreement and continuing until the earlier to occur of the termination of this Agreement pursuant to Article VIII and the Closing, the Company shall afford Purchaser reasonable access, consistent with applicable Law, during normal business hours, on reasonable advance notice provided in writing to the General Counsel of the Company, or another Person designated in writing by the Company, to the properties, books and records and personnel of the Company, except that the Company may restrict or otherwise prohibit access to any documents or information to the extent that (a) any applicable Law or Contract requires the Company to restrict or otherwise prohibit access to such documents or information (in which case, the Company shall use reasonable best efforts to provide such access as can be provided (or otherwise convey such information regarding the applicable matter as can be conveyed) in compliance with such applicable Law or Contract), (b) access to such documents or information would give rise to a material risk of waiving any attorney-client privilege, work product doctrine or other privilege applicable to such documents or information (in which case, the Company shall use reasonable best efforts to provide such access as can be provided (or otherwise convey such information regarding the applicable matter as can be conveyed) without jeopardizing such privilege), (c) such disclosure relates to interactions with other prospective buyers or transaction partners of the Company or the

58

negotiation of this Agreement and the transactions contemplated hereby, or information relating to the analysis, valuation or consideration of the Transactions or the other transactions contemplated hereby, in each case, subject to Section 5.3, which shall not be limited by this Section 6.7 or (d) access would result in the disclosure of any trade secrets of third Persons. Nothing in this Section 6.7 shall be construed to require the Company, any of its Subsidiaries or any of their respective Representatives to prepare any reports, analyses, appraisals or opinions. Any investigation conducted pursuant to the access contemplated by this Section 6.7 shall be conducted in a manner that is consistent with all applicable COVID-19 Measures and (i) that does not unreasonably interfere with the conduct of the business of the Company and its Subsidiaries or otherwise result in any significant interference with the prompt and timely discharge by officers, employees and other authorized Representatives of the Company or any of its Subsidiaries of their normal duties or (ii) create a risk of damage or destruction to any property or assets of the Company or its Subsidiaries. Any access to the properties of the Company and its Subsidiaries shall be subject to the Company’s reasonable security measures and insurance requirements and will not include the right to perform invasive or subsurface testing or any sampling, monitoring or analysis of soil, groundwater, building materials, indoor air, or other environmental media of the sort generally referred to as a “Phase II” environmental investigation. The terms and conditions of the Confidentiality Agreement shall apply to any information obtained by Purchaser or any of its Representatives in connection with any investigation conducted pursuant to the access contemplated by this Section 6.7. Notwithstanding anything to the contrary in this Agreement, each Party may satisfy its obligations set forth in this Section 6.7 by electronic means if physical access would not be permitted under applicable COVID-19 Measures.

6.15 Transfer Restrictions.

Thereafter, Purchaser shall not Transfer any shares of Series B-1 Preferred Stock held by Purchaser, including any Underlying Shares issued or issuable upon conversion of such shares of Series B-1 Preferred Stock, to an Activist Investor, to a Competitor or to any Person that would beneficially own, after giving effect to such Transfer, five percent or more of the outstanding Company Common Stock (measured on as-converted basis), in each case, to the extent that the identity of the transaction counterparty can be reasonably ascertained and such Person meets the applicable definition thereof to Purchaser’s knowledge after reasonable inquiry; provided, that the provisions of the foregoing clause shall not apply to (A) any block trade in which a broker-dealer will attempt to sell the shares to a third-party as agent or other similar transactions with a financial intermediary, (B) any Transfer into the public market pursuant to a bona fide, broadly distributed underwritten public offering or (C) any Transfers through a bona fide sale to the public that is not directed at a particular transferee, without registration effectuated pursuant to Rule 144 under the Securities Act.

(i) Transfers to any Affiliate of Purchaser, including an affiliated investment fund, co-investment vehicle or aggregator vehicle (or equivalent) that is controlled, managed or advised by Purchaser or an Affiliate of Purchaser;

6.16 Pre-Emptive Rights.

(a) Following the Closing Date, so long as Purchaser Parties, collectively, continue to beneficially own at least 25% of the Acquired Shares (including Underlying Shares issued on conversion of such Acquired Shares), calculated on an as-converted basis, if the Company proposes to issue or sell any Equity Securities (other than any Excluded Securities) (“New Securities”) to any Person or Persons (the “Offeree”), the Company shall first offer to sell to each Purchaser Party a portion of such New Securities equal to the (i) the number of shares of Company Common Stock beneficially owned by such Purchaser Party divided by (ii) the total number of shares of Company Common Stock issued and outstanding, in each case as of immediately prior to such issuance and determined on an as-converted basis (the “Preemptive Percentage”). The Purchaser Parties shall be entitled to purchase such New Securities at the same price, on the same terms and subject to the same conditions as are to be offered to the Offeree. The Purchaser Parties electing to purchase their Preemptive Percentage of the New Securities proposed to be issued or sold to the Offeree (“Participating Parties”) shall take all necessary actions in connection with the consummation of the purchase transactions contemplated by this Section 6.16 as requested by the Company Board, including the execution of all agreements, documents and instruments in connection therewith in the form presented by the Company, so long as such agreements, documents and instruments are on customary forms for such a transaction and do not require such Participating Parties to make or agree to any representation, warranty, covenant or indemnity that is more burdensome than that required of the Offeree in the agreements, documents or instruments in connection with such transaction. If any Purchaser Party or any Viking Party elects not to purchase all of the New Securities that it is entitled to purchase pursuant to the first sentence of this Section 6.16 or the first sentence of Section 6.16 of the Viking Purchase Agreement, as applicable, each Participating Party that has elected to purchase its Preemptive Percentage of the New Securities proposed to be issued or sold to the Offeree (together with any Viking Party that has elected to purchase its Preemptive Percentage of such New Securities, the “Fully Participating Parties”) shall be entitled to purchase an additional number of New Securities equal to the aggregate number of New Securities that the Purchaser Parties and/or Viking Parties elected not to purchase; provided, that if there is an oversubscription in respect of such remaining New Securities due to more than one Fully Participating Party requesting additional New Securities, the oversubscribed amount shall be fully allocated among the Fully Participating Parties pro rata based on such Fully Participating Parties’ relative Preemptive Percentages.

63

(b) In order to exercise its purchase rights hereunder, a Purchaser Party shall, within 15 days after receipt of written notice (an “Offer Notice”) from the Company describing the New Securities being offered, the purchase price thereof, the payment terms and such Purchaser Party’s percentage allotment, deliver a written notice to the Company describing its election hereunder (which election shall be absolute and unconditional other than being conditioned upon the consummation of the issuance or sale to the Offeree). If the Company receives no such notice from the Purchaser within 15 days after the Offer Notice is given, the Company shall be deemed to have notified the Company that it does not elect to participate.

(c) In connection with any exercise by Purchaser of its rights to purchase New Securities pursuant to this Agreement, the Company will cooperate with the Purchaser as reasonably requested by the Purchaser to complete any such purchase, including, to the extent requested by the Purchaser, entering into “blocker” arrangements with respect to derivative securities and effecting any required filings or notices required by any governmental agency at the Purchaser’s sole cost and expense. Purchaser shall take all such actions as may be reasonably necessary to complete any such purchase, including, without limitation, providing such information to the Company as requested in order to determine the Purchaser’s Preemptive Percentage and entering into such additional agreements as may be necessary and appropriate.

(d) During the 90 days following the expiration of the 15-day offering period described in Section 6.16(b), the Company shall be entitled to sell any New Securities that the Purchaser Parties have not elected to purchase to the Offeree at a price no less than the purchase price, and on other terms and subject to other conditions no more favorable than those, stated in the notice provided under Section 6.16(b) (in addition to the New Securities that the Company is not required to offer to the Purchaser Parties pursuant to the first sentence of Section 6.16(a)). Any New Securities proposed to be issued or sold by the Company to the Offeree after such 90-day period, or at a price or on terms or subject to conditions not complying with the preceding sentence, shall be reoffered to the Purchaser Parties pursuant to the terms of this Section 6.16 prior to any issuance or sale to the Offeree.

(e) For purposes of determining the Purchaser’s beneficial ownership of Company Common Stock, the Company shall be permitted to rely on any information provided to the Company by Purchaser and any public disclosures made by Purchaser.

(f) In the case of a proposed issuance or sale of New Securities for consideration in whole or in part other than cash, including securities acquired in exchange therefor, for purposes of this Section 6.16 the consideration other than cash shall be deemed to be cash in an amount equal to the fair value of such consideration as reasonably determined by the Company Board; provided, that such fair value as determined by the Company Board shall not exceed the aggregate market price of the securities being offered as of the date the Company Board authorizes the offering of such securities.

(g) Notwithstanding anything in this Agreement to the contrary, a Purchaser Party may designate any of its Permitted Transferees to purchase all or part of the New Securities offered to such Purchaser Party pursuant to Section 6.16(a); provided, that such Purchaser Party shall remain obligated to consummate the purchase if such designee fails to do so.

64

(iii) form, join or in any way participate in a “group” (as defined in Section 13(d)(3) of the Exchange Act) in connection with any Voting Stock of the Company or its Subsidiaries, including with the Viking Purchaser; provided, that taking any action contemplated by this Agreement shall not constitute a violation of this Section 6.17(a)(iii); or

(iv) take any action that would reasonably be expected to require the Company to make a public announcement regarding any actions prohibited by this Section 6.17(a);

provided, that nothing contained in this Section 6.17(a) shall limit, restrict or prohibit (x) any confidential, non-public discussions with or communications or proposals to management or the Company Board by Purchaser or its Affiliates or Representatives related to any of the foregoing, (y) any Purchaser Party’s ability to vote, Transfer, convert, exercise its rights under Section 6.16 or otherwise exercise rights with respect to its Series B-1 Preferred Stock or Company Common Stock in accordance with the terms and conditions of this Agreement and the Certificate of Designations or (z) the ability of the Series B-1 Preferred Director to vote or otherwise exercise his or her duties or otherwise act in his or her capacity as a member of the Company Board.

8.2 Manner and Notice of Termination; Effect of Termination.

The Party terminating this Agreement pursuant to Section 8.1 (other than pursuant to Section 8.1(a)) shall deliver prompt written notice thereof to the other Party specifying the provision of Section 8.1 pursuant to which this Agreement is being terminated and setting forth in reasonable detail the facts and circumstances forming the basis for such termination pursuant to such provision.

(b) Effect of Termination. Any proper and valid termination of this Agreement pursuant to Section 8.1 shall be effective immediately on the delivery of written notice by the terminating Party to the other Party. In the event of the termination of this Agreement pursuant to Section 8.1, this Agreement shall be of no further force or effect without liability of either Party (or any partner, member, stockholder, director, officer, employee, Affiliate or Representative of such Party) to the other Party, as applicable, except that this Section 8.2, Section 8.3 and Article IX shall each survive the termination of this Agreement. Notwithstanding the foregoing, nothing in this Agreement or the termination hereof shall relieve either Party from any liability for intentional fraud in respect of the statements made in this Agreement or any Willful Breach prior to its termination. The rights and obligations under the Confidentiality Agreement shall survive in accordance with the terms of the Confidentiality Agreement.

8.3 Fees and Expenses.

(a) General. Except as set forth in this Section 8.3 and in Section 9.2(b), all fees and expenses incurred in connection with this Agreement and the Casdin Transaction will be paid by the Party incurring such fees and expenses whether or not the Casdin Transaction is consummated.

(b) Company Payments.

(i) The Company shall, at or prior to the earlier to occur of (A) the date that is three Business Days following the termination of this Agreement pursuant to Section 8.1 (other than any termination pursuant to Section 8.1(g)) and (B) the Closing, reimburse Purchaser (or cause Purchaser to be reimbursed) for an amount not to exceed $1,250,000 in cash, by wire transfer of immediately available funds, for Purchaser’s documented expenses incurred in connection with this Agreement and the transactions contemplated hereby (collectively, the “Expense Reimbursement”).

(ii) If this Agreement is terminated by Purchaser or the Company pursuant to Section 8.1(d), then the Company shall promptly (and in any event within two Business Days) after such termination pay, or cause to be paid, to Purchaser an amount equal to $1,250,000 in cash, less any amount previously paid to Purchaser pursuant to Section 8.3(b)(i) (the “Company Termination Fee”), by wire transfer of immediately available funds (and, following such payment, no additional amounts shall be payable under Section 8.3(b)(i)).

(iii) If this Agreement is terminated by Purchaser pursuant to Section 8.1(f), then the Company shall promptly (and in any event within three Business Days) after such termination pay, or cause to be paid, to Purchaser an amount equal to $5,000,000 in cash (the “Change of Recommendation Termination Fee”), by wire transfer of immediately available funds.

71

(iv) If, within 12 months following termination of this Agreement by Purchaser or the Company pursuant to Section 8.1(d) or by Purchaser pursuant to Section 8.1(e), either (A) an Acquisition Transaction is consummated (other than in connection with the conversion of the Company’s Convertible Notes) or (B) the Company enters into a definitive agreement providing for an Acquisition Transaction, then the Company shall promptly (and in any event within three Business Days) after the earlier to occur of the events described in clauses (A) and (B), pay, or cause to be paid, to Purchaser an amount equal to $2,500,000 in cash (the “Acquisition Termination Fee”), by wire transfer of immediately available funds. For purposes of this Section 8.3(b)(ii), all references to “10%” in the definition of “Acquisition Transaction” shall be deemed to be references to “20%.”

(c) Payments; Default. The Parties acknowledge that the agreements contained in this Section 8.3 are an integral part of the Casdin Transaction, and that the damages resulting from the termination of this Agreement under circumstances where the Company Termination Fee, Change of Recommendation Termination Fee, Acquisition Termination Fee or Expense Reimbursement is payable are uncertain and incapable of accurate calculation and that, without these agreements, the Parties would not enter into this Agreement, and, therefore, the Company Termination Fee, Change of Recommendation Termination Fee, Acquisition Termination Fee or Expense Reimbursement, if, as and when required to be paid pursuant to this Section 8.3, shall not constitute a penalty, but rather liquidated damages, and in a reasonable amount that will compensate the Party receiving such amount in the circumstances in which it is payable for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Casdin Transaction. Accordingly, if the Company fails to timely pay any amount due pursuant to Section 8.3(b) and, in order to obtain such payment, Purchaser commences a Legal Proceeding that results in a judgment against the Company for the amount set forth in Section 8.3(b) or any portion thereof, the Company shall pay to Purchaser its costs and expenses (including reasonable attorneys’ fees) in connection with such Legal Proceeding, together with interest on such amount or portion thereof at the annual rate of 5% plus the prime rate as published in The Wall Street Journal in effect on the date that such payment or portion thereof was required to be made through the date that such payment or portion thereof was actually received, or a lesser rate that is the maximum permitted by applicable Law.

(d) Exclusivity of Remedies.

(i) Notwithstanding anything in this Agreement to the contrary, but subject to the last sentence of Section 8.3(c) and to this Section 8.3(d), in the event of any valid termination of this Agreement pursuant to Section 8.1 where the Company Termination Fee, the Change of Recommendation Termination Fee or the Acquisition Termination Fee is payable pursuant to Section 8.3(b) and such fee is actually paid to Purchaser or its designee, such fee (together with any Expense Reimbursement previously paid to Purchaser and any other fee that may be payable pursuant to Section 8.3(b)) shall constitute the sole and exclusive remedy of Purchaser against the Company Related Parties

72

for any loss suffered as a result of the failure of the transactions contemplated by this Agreement and the Transaction Documents to be consummated, and on payment of the Company Termination Fee, the Change of Recommendation Termination Fee or Acquisition Termination Fee, as applicable (together with any Expense Reimbursement payable hereunder and any other fee that may be payable pursuant to Section 8.3(b)), none of the Company Related Parties shall have any further liability or obligation relating to or arising out of this Agreement and the Transaction Documents (except that Purchaser may be entitled to remedies with respect to the Confidentiality Agreement, Section 8.3(a) and the last sentence of Section 8.3(c), as applicable); provided, that this Section 8.3(d)(i) shall not apply in the case of intentional fraud in respect of the statements made in this Agreement or any Willful Breach prior to its termination. The Parties acknowledge and agree that, subject to the last sentence of Section 8.3(c), in no event shall the Company be required to pay the Expense Reimbursement on more than one occasion, the Company Termination Fee on more than one occasion, the Change of Recommendation Termination Fee on more than one occasion or the Acquisition Termination Fee on more than one occasion.

(ii) Subject to Section 8.1 and Section 8.3(d)(iii), if Purchaser breaches this Agreement, the Company’s right to (A) seek an injunction, specific performance or other equitable relief in accordance with the terms and limitations of Section 9.8(b) or (B) terminate this Agreement and seek money damages from Purchaser in the event of intentional fraud in respect of the statements made in this Agreement or Willful Breach by Purchaser prior to termination shall be the sole and exclusive remedies (whether such remedies are sought in equity or at law, in contract, in tort or otherwise) of any of the Company Related Parties against any of the Purchaser Related Parties for any losses, damages, costs, expenses, obligations or liabilities arising out of or related to this Agreement (or any breach of any representation, warranty, covenant, agreement or obligation contained herein), the transactions contemplated by this Agreement (or any failure of such transactions to be consummated) or in respect of any oral representations made or alleged to be made in connection with this Agreement, the transactions contemplated herein or therein or otherwise (except that the Parties (or their Affiliates) shall remain obligated with respect to, and the Company and its Subsidiaries may be entitled to remedies with respect to, the Confidentiality Agreement and Section 8.3(a)).

(iii) While each of the Company and Purchaser may pursue a grant of specific performance in accordance with Section 9.8(b), under no circumstances shall the Company or Purchaser be permitted or entitled to receive both (A) a grant of specific performance that results in the Closing occurring and (B) any money damages (including the Company Termination Fee, the Change of Recommendation Termination Fee and the Acquisition Termination Fee but, for the avoidance of doubt, excluding the Expense Reimbursement).

8.4 Amendment. Subject to applicable Law and subject to the other provisions of this Agreement, this Agreement may be amended by the Parties at any time by execution of an instrument in writing signed on behalf of Purchaser and the Company (pursuant to authorized action by the Company Board (or a committee thereof)); provided, that in the event that the Company has received the Requisite Stockholder Approval, no amendment may be made to this

73

Agreement that requires the approval of the Company Stockholders pursuant to the NASDAQ rules without such approval. Notwithstanding the foregoing, (a) no Transaction Document shall be amended or waived in any manner that would impair, impede or materially delay the consummation of the Viking Transaction (or terminated (other than a termination (excluding a termination due to mutual agreement) in accordance with its terms)) without the prior written consent of the Viking Purchaser and (b) any amendment or waiver that expands the rights or limits the obligations or liabilities of Purchaser hereunder shall, at the Viking Purchaser’s option, be deemed to be made with respect to the Viking Purchase Agreement and apply to the Viking Purchaser. In furtherance of the preceding sentence, the Company shall provide prompt written notice to the Viking Purchaser of any amendment or waiver of this Agreement. The Viking Purchaser is an express third-party beneficiary of the prior two sentences of this Section 8.4.

8.5 Extension; Waiver. At any time and from time to time prior to the Closing, either Party may, to the extent legally allowed and except as otherwise set forth herein (a) extend the time for the performance of any of the obligations or other acts of the other Party, as applicable, (b) waive any inaccuracies in the representations and warranties made to such Party contained herein or in any document delivered pursuant hereto and (c) subject to the requirements of applicable Law, waive compliance with any of the agreements or conditions for the benefit of such Party contained herein. Any agreement on the part of either Party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed by such Party. Any delay in exercising any right pursuant to this Agreement shall not constitute a waiver of such right.

9.2 Tax Matters.

(a) Withholding. The Company and its paying agent shall be entitled to deduct or withhold on all applicable payments made to Purchaser whether in the form of cash or otherwise such Tax amounts as the Company reasonably determines are required to be deducted or withheld therefrom under any provision of applicable Law (and, to the extent such amounts are paid to the relevant taxing authority in accordance with applicable Law, such amounts will be treated for all

75

purposes of this Agreement as having been paid to the Person in respect of which such withholding was made); provided, for the avoidance of doubt, that if the Company determines that an amount is required to be deducted or withheld on any payment with respect to Purchaser, the Company shall provide reasonable prior notice to Purchaser in writing of its intent to deduct or withhold Taxes on such payment and shall reasonably cooperate with Purchaser in obtaining any available exemption or reduction of such withholding.

(b) Transfer Taxes. The Company shall pay any and all Transfer Taxes due on (i) the issue of the Acquired Shares and (ii) the issue of shares of Company Common Stock on conversion of the Acquired Shares. However, the Company shall not be required to pay any Transfer Tax that may be payable in respect of the issue or delivery (or any transfer involved in the issue or delivery) of Acquired Shares or shares of Company Common Stock issued on conversion of the Acquired Shares to a beneficial owner other than the initial beneficial owner of the Acquired Shares, and no such issue or delivery shall be made unless and until the person requesting such issue or delivery has paid to the Company the amount of any such Transfer Tax or has established to the reasonable satisfaction of the Company that such Transfer Tax has been paid or is not payable.

(c) Intended Tax Treatment. Purchaser and the Company agree not to treat the Series B-1 Preferred Stock (based on the terms set forth in the Certificate of Designations) as “preferred stock” for purposes of Section 305 of the Code and the Treasury Regulations promulgated thereunder, and, as a consequence, no difference between the purchase price paid for the Series B-1 Preferred Stock and the Liquidation Preference (as defined in the Certificate of Designations) thereof shall, by reason of Section 305(b)(4) of the Code or Treasury Regulations Section 1.305-5, be treated as a distribution of property until paid in cash. The Company and Purchaser (and their respective Affiliates) shall file all Tax Returns in a manner consistent with the foregoing intended Tax treatment and shall not take any Tax position that is inconsistent with such intended Tax treatment except in connection with, or as required by, any of the following: (i) a change in relevant Law or official guidance from a taxing authority occurring after the Closing Date, (ii) after the Closing Date, the promulgation of relevant final U.S. Treasury Regulations addressing instruments similar to the Series B-1 Preferred Stock (from and after the effective date of such regulations), (iii) an amendment to the terms of the Certificate of Designations or (iv) a “determination” within the meaning of section 1313(a) of the Code.

9.3 Assignment. No Party may assign either this Agreement or any of its rights, interests, or obligations hereunder, by operation of Law or otherwise, without the prior written approval of the other Party; provided, that Purchaser or any Purchaser Party may assign its rights, interests and obligations under this Agreement, in whole or in part, to one or more Permitted Transferees that agree in writing to be bound by the provisions of this Agreement, including the rights, interests and obligations so assigned, so long as such assignment does not impede or delay the consummation of the Closing; provided, further, that no such assignment will relieve any Purchaser Party of its obligations hereunder prior to the Closing.

9.4 Entire Agreement. This Agreement and the documents and instruments and other agreements between the Parties as contemplated by or referred to herein, including the Confidentiality Agreement and the Company Disclosure Letter, constitute the entire agreement between the Parties with respect to the subject matter hereof and supersede all prior agreements

76

and understandings, both written and oral, between the Parties with respect to the subject matter hereof. Notwithstanding anything to the contrary in this Agreement, the Confidentiality Agreement shall: (a) not be superseded; (b) survive any termination of this Agreement in accordance with its terms; and (c) continue in full force and effect until the earlier to occur of the Closing and the date on which the Confidentiality Agreement expires in accordance with its terms or is validly terminated by the parties thereto. Purchaser and its Representatives shall hold and treat all documents and information concerning the Company and its Subsidiaries furnished or made available to Purchaser or its Representatives pursuant to Section 6.7 in accordance with the Confidentiality Agreement.

9.5 Survival. All of the covenants or other agreements of the Parties contained in this Agreement shall survive until fully performed or fulfilled, unless and to the extent that non-compliance with such covenants or agreements is waived in writing by the party entitled to such performance. Except for the Company Fundamental Representations and the Purchaser Fundamental Representations, which shall survive until the sixth anniversary of the Closing Date, the representations and warranties made herein shall survive for 12 months following the Closing Date and shall then expire; provided, that nothing herein shall relieve any party of liability for any inaccuracy or breach of such representation or warranty to the extent that any good faith allegation of such inaccuracy or breach is made in writing prior to such expiration by a Person entitled to make such claim pursuant to the terms and conditions of this Agreement.

9.6 Third Party Beneficiaries. Unless expressly set forth herein, this Agreement is not intended to and shall not confer any rights or remedies on any person other than the Parties, their respective successors and permitted assigns.

9.7 Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement will continue in full force and effect and the application of such provision to other Persons or circumstances will be interpreted so as reasonably to effect the intent of the Parties. On such a determination, the Parties agree to negotiate in good faith to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision. If any provision of this Agreement is so broad as to be unenforceable, such provision will be interpreted to be only so broad as it is enforceable.

9.8 Remedies.

(a) Remedies Cumulative. Except as otherwise provided herein, any and all remedies herein expressly conferred on a Party will be deemed cumulative with and not exclusive of any other remedy conferred hereby or by Law or equity on such Party, and the exercise by a Party of any one remedy will not preclude the exercise of any other remedy. Except as set forth in Section 8.3(d)(iii), the Parties agree that (i) by seeking the remedies provided for in this

77

Section 9.8, a Party shall not in any respect waive its right to seek any other form of relief that may be available to a Party under this Agreement and (ii) nothing set forth in this Section 9.8 shall require any Party to institute any Legal Proceeding for (or limit any Party’s right to institute any Legal Proceeding for) injunctive relief or specific performance under this Section 9.8 prior or as a condition to exercising any termination right under Article VIII (and pursuing damages after such termination), nor shall the commencement of any Legal Proceeding pursuant to this Section 9.8 or anything set forth in this Section 9.8 restrict or limit any Party’s right to terminate this Agreement in accordance with the terms of Article VIII or pursue any other remedies under this Agreement or applicable Law that may be available then or thereafter.

(b) Specific Performance.

(i) The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy would occur in the event that the Parties do not perform the provisions of this Agreement (including any Party failing to take such actions as are required of it hereunder in order to consummate this Agreement) in accordance with its specified terms or otherwise breach such provisions. The Parties acknowledge and agree that: (A) the Parties shall be entitled, in addition to any other remedy to which they are entitled at Law or in equity, to an injunction, specific performance and other equitable relief to prevent breaches (or threatened breaches) of this Agreement in accordance with its specified terms and to enforce specifically the terms and provisions hereof; (B) the provisions of Section 8.3 are not intended to and do not adequately compensate the Company, on the one hand, or Purchaser, on the other hand, for the harm that would result from a breach of this Agreement, and will not be construed to diminish or otherwise impair in any respect any Party’s right to an injunction, specific performance and other equitable relief; and (C) the right of specific enforcement (including specific performance of the Parties’ obligations to effect the Closing) is an integral part of the Casdin Transaction and without that right, neither the Company nor Purchaser would have entered into this Agreement.

(ii) The Parties agree not to raise any objections based on the adequacy of legal remedies or the enforceability of this Section 9.8 to: (A) the granting of an injunction, specific performance or other equitable relief to prevent or restrain breaches or threatened breaches of this Agreement by the Company, on the one hand, or Purchaser, on the other hand; and (B) the specific performance of the terms and provisions of this Agreement to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants, obligations and agreements of Purchaser pursuant to this Agreement. Any Party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement will not be required to provide any bond or other security in connection with such injunction or enforcement, and each Party irrevocably waives any right that it may have to require the obtaining, furnishing or posting of any such bond or other security. Each Party agrees that it shall use reasonable best efforts to cooperate with the other Party in seeking and agreeing to an expedited schedule in any litigation seeking an injunction or order of specific performance to attempt to fully resolve any dispute between the Parties prior to the Termination Date.

9.9 Governing Law. This Agreement and all actions, proceedings or counterclaims (whether based on contract, tort or otherwise) arising out of or relating to this Agreement, any transaction contemplated hereby or the actions of Purchaser or the Company in the negotiation, administration, performance and enforcement thereof, shall be governed by, and construed in accordance with the Laws of the State of Delaware, including its statute of limitations, without giving effect to any choice or conflict of Laws provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware.

9.10 Consent to Jurisdiction. Each of the Parties: (a) irrevocably consents to the service of the summons and complaint and any other process (whether inside or outside the territorial jurisdiction of the Chosen Courts) in any Legal Proceeding relating to the Casdin Transaction, for and on behalf of itself or any of its properties or assets, in accordance with Section 9.1 or in such other manner as may be permitted by applicable Law, and nothing in this Section 9.10 shall affect the right of any Party to serve legal process in any other manner permitted by applicable Law; (b) irrevocably and unconditionally consents and submits itself and its properties and assets in any Legal Proceeding to the exclusive general jurisdiction of the Court of Chancery of the State of Delaware and any state appellate court therefrom within the State of Delaware (or, solely if the Court of Chancery of the State of Delaware declines to accept jurisdiction over a particular matter, any other state or federal court within the State of Delaware) (the “Chosen Courts”) in the event of any dispute or controversy relating to or arising out of this Agreement or the transactions contemplated hereby or thereby; (c) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court; (d) agrees that any Legal Proceeding relating to or arising out of this Agreement or the transactions contemplated hereby or thereby will be brought, tried and determined only in the Chosen Courts; (e) waives any objection that it may now or hereafter have to the venue of any such Legal Proceeding in the Chosen Courts or that such Legal Proceeding was brought in an inconvenient court and agrees not to plead or claim the same; and (f) agrees that it will not bring any Legal Proceeding relating to or arising out of this Agreement or the transactions contemplated hereby or thereby in any court other than the Chosen Courts unless the Chosen Courts issue a final judgment determining that such court lacks jurisdiction. Purchaser and the Company agree that a final judgment and any interim relief (whether equitable or otherwise) in any Legal Proceeding in the Chosen Courts will be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Law.

9.11 WAIVER OF JURY TRIAL. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE PURSUANT TO THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT THAT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LEGAL PROCEEDING (WHETHER FOR BREACH OF CONTRACT, TORTIOUS CONDUCT OR OTHERWISE) DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTION. EACH PARTY ACKNOWLEDGES AND AGREES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER; (ii) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER; (iii) IT MAKES THIS WAIVER VOLUNTARILY; AND (iv) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.11.

9.12 No Recourse. All claims, obligations, liabilities, or causes of action (whether in contract or in tort, in law or in equity, or granted by statute) that may be based on, in respect of, arise under, out or by reason of, be connected with, or relate in any manner to this Agreement, or the negotiation, execution, or performance of this Agreement (including any representation or warranty made in, in connection with, or as an inducement to, this Agreement), may be made only against (and such representations and warranties are those solely of) the Persons that are expressly identified as parties in the preamble to this Agreement (the “Contracting Parties”).

Without limiting the foregoing, to the maximum extent permitted by applicable Law: (a) each Contracting Party hereby waives and releases any and all rights, claims, demands, or causes of action that may otherwise be available at law or in equity, or granted by statute, to avoid or disregard the entity form of a Contracting Party or otherwise impose liability of a Contracting Party on any Nonparty Affiliate, whether granted by statute or based on theories of equity, agency, control, instrumentality, alter ego, domination, sham, single business enterprise, piercing the veil, unfairness, undercapitalization, or otherwise; and (b) each Contracting Party disclaims any reliance on any Nonparty Affiliates with respect to the performance of this Agreement or any representation or warranty made in, in connection with, or as an inducement to this Agreement. Notwithstanding anything to the contrary in this Section 9.12, nothing in this Section 9.12 shall be deemed to limit any liabilities or obligations of, or claims against, (x) any party to any other Transaction Document or serve as a waiver of any right on the part of any party to such other Transaction Document to initiate any Legal Proceedings permitted by, pursuant to, and in accordance with the specific terms of such other Transaction Document or (y) any Person in respect of intentional fraud in respect of the statements made in this Agreement.
