AGREEMENT AND PLAN OF MERGER

This AGREEMENT AND PLAN OF MERGER, made and entered into as of May 17, 2014 (as amended, supplemented or otherwise modified from time to time, this “Agreement”), is by and among CareDx, Inc., a Delaware corporation (“Parent”), Monitor Acquisition Corporation, a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”), ImmuMetrix, Inc., a Delaware corporation (“Company”), and Xxxxxxx Xxxxxxx as the Holders’ Agent, for the purposes of Article VII only. Certain capitalized terms used herein have the meanings assigned to in Annex A.

RECITALS

A. The Boards of Directors of Parent, Merger Sub and Company believe it is in the best interests of their respective corporations and the stockholders of their respective corporations that Company be acquired by Parent through the statutory merger of the Merger Sub with and into the Company (the “Merger”) and, in furtherance thereof, have approved this Agreement, and, as part of the same overall transaction, pursuant to the Second Step Merger (as defined below) the surviving entity of the Merger would merge with and into a limited liability company wholly owned by Parent.

B. In connection with the Merger, (i) the outstanding shares of the Company’s capital stock held by Persons that are “accredited investors” (“Accredited Investors”), within the meaning of Regulation D, Rule 501(a), promulgated by the Securities and Exchange Commission under the Securities Act of 1933 (the “Securities Act”), shall be converted into the right to receive cash and Parent Shares, and (ii) the outstanding shares of Company’s capital stock held by Persons that are Unaccredited Investors shall be converted into the right to receive cash.

C. A portion of the Merger Consideration will be placed in escrow by Parent, as partial security for the indemnification obligations of the Indemnifying Securityholders.

D. In order to induce Parent to enter into this Agreement, certain Designated Consultants are executing and delivering consulting agreements (the “Consulting Agreement”) and certain Continuing Employees are executing and delivering employment offer letters (the “Offer Letters”), in each case, effective at and subject to the occurrence of the Closing.

NOW, THEREFORE, in consideration of the representations, warranties and agreements set forth herein, the parties hereto hereby agree as follows:

ARTICLE I

THE MERGER

1.1 The Merger. Upon the terms and subject to the conditions in this Agreement, and in accordance with the Delaware General Corporation Law (the “DGCL”), Merger Sub will be merged with and into the Company (the “Merger”), pursuant to the certificate of merger, substantially in the form of Exhibit A (the “Certificate of Merger”), to be filed with the Secretary of State of Delaware concurrently with or as soon as practicable following the Closing. The Merger will become effective at the time of the filing of such Certificate of Merger with the Delaware Secretary of State (the “Effective Time”). The Company will be the surviving corporation (sometimes referred to as the “Surviving Corporation”) in the Merger and will succeed to and assume all the rights and obligations of Merger Sub in accordance with the DGCL.

1.2 Closing. The closing of the Merger (the “Closing”) will take place as soon as practicable (and in any event within three (3) Business Days) after the satisfaction or waiver of each of the conditions set forth in Article VI, (except for such conditions that by their nature will be satisfied at Closing) or at such other time as the parties agree in writing. The Closing will take place at the offices of Xxxxxx Xxxxxxx Xxxxxxxx & Xxxxxx, P.C., 000 Xxxx Xxxx Xxxx, Xxxx Xxxx, Xxxxxxxxxx 00000 or at such other location as the parties agree. The date on which the Closing actually occurs is herein referred to as the “Closing Date.”

1.3 Cash Payments. Upon execution of this Agreement and delivery by the Company of the Company Requisite Stockholder Approvals, Parent shall make a non-refundable payment to the Company in the amount of Four Hundred Thousand Dollars ($400,000) (the “Initial Cash Payment”) by check or wire transfer. An additional Two Hundred Thousand Dollars ($200,000) (the “Cash Payment Amount”) shall be payable by Parent subject to and in accordance with Section 1.7(e).

1.4 Newco Spin-off. Prior to the Closing, the Company shall (i) form a wholly-owned subsidiary (“Newco”), (ii) enter into an agreement with Newco, in the form attached hereto as Exhibit B (the “Asset Transfer Agreement”), which includes an agreement of Newco to be bound by Section 1.7(e) of this Agreement and transfers to Newco certain Intellectual Property, records and other assets (both tangible and intangible) of the Company as set forth in more detail in the Asset Transfer Agreement, (iii) subject to Parent’s review and acceptance of the Estimated Closing Date Balance Statement, contribute to Newco cash up to the amount of the Company Surplus Cash, and (iv) distribute all shares of Newco by dividend to the Company stockholders (collectively, the “Newco Spin-off”). The fair market value of Newco and the related consequences to the Company and the Company Stockholders will be determined based on a report obtained by the Company from Teknos Associates in connection with the Newco Spinoff. Following the Newco Spin-off, and prior to the Closing, Newco and Company will enter into that certain Sublicense Agreement attached hereto as Exhibit C, in consideration of certain undertakings by Newco therein, and the Non-competition and Non-solicitation Agreement attached hereto as Exhibit E.

1.5 Effects of the Merger.

(a) General. At the Effective Time, the effect of the Merger will be as provided in this Agreement, the Certificate of Merger and the applicable provisions of the DGCL.

(b) Certificate of Incorporation. At the Effective Time, the Company’s Certificate of Incorporation will be amended such that the certificate of incorporation of Merger Sub, as in effect immediately prior to the Effective Time, will be the certificate of incorporation of the Surviving Corporation; provided, however, that at the Effective Time, Article I of the certificate of incorporation of the Surviving Corporation shall be amended and restated in its entirety to read as follows: “The name of the corporation is ImmuMetrix, Inc.”

(c) Bylaws. At the Effective Time, the bylaws of Merger Sub, as in effect immediately prior to the Effective will be the bylaws of the Surviving Corporation.

(d) Directors and Officers of Surviving Corporation. At the Effective Time, the directors and officers of Merger Sub, as constituted immediately prior to the Effective Time, will be the directors and officers of the Surviving Corporation.

1.6 Effect on Company Capital Stock and Options.

(a) Company Preferred Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of Company Capital Stock, each share of Company

-2-

Preferred Stock issued and outstanding prior to the Effective Time (other than Dissenting Shares and shares owned by Unaccredited Investors that receive cash in lieu of Parent Shares) shall be automatically converted into the right to receive, subject to and in accordance with Section 1.10:

(i) the Preferred Stock Closing Stock Amount Per Share;

(ii) upon release from the Escrow pursuant to Section 7.5 and subject to the terms and conditions set forth in this Agreement, the Preferred Stock Escrow Amount Per Share (subject to reduction for payment of Indemnifiable Losses pursuant to Article VII); and

(iii) the Preferred Stock Earnout Amount Per Share associated with any Earnout Consideration payable pursuant to Section 1.9 (subject to set-off for payment of Indemnifiable Losses pursuant to Article VII).

(b) Common Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of Company Capital Stock, each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than Dissenting Shares and shares owned by Unaccredited Investors that receive cash in lieu of Parent Shares) shall be automatically converted into the right to receive, subject to and in accordance with Section 1.9:

(i) the Common Stock Closing Stock Amount Per Share;

(ii) upon release from the Escrow pursuant to Section 7.5, the Common Stock Escrow Amount Per Share (subject to reduction for payment of Indemnifiable Losses pursuant to Article VII); and

(iii) the Common Stock Earnout Amount Per Share payable pursuant to Section 1.9 (subject to set-off for payment of Indemnifiable Losses pursuant to Article VII).

(c) Shares held by Unaccredited Investors. As a condition to receipt of Parent Shares pursuant to Section 1.6(a) or Section 1.6(b), Company Stockholders shall be required to comply with the requirements of Section 1.10, including but not limited to the delivery to Parent of an Accredited Investor questionnaire to be provided by Parent. For any Company Stockholders who are not Accredited Investors, Parent shall have the right, but not the obligation, to substitute cash for all Parent Shares to which all such Company Stockholders would otherwise be entitled under this Agreement, based on the fair value per share of the Parent Shares on the Closing Date, but Parent shall not be entitled to substitute cash for less than all Parent Shares to which all such Company Stockholders would otherwise be entitled. Such fair value shall be $2.55 per Parent Share, as determined by Financial Strategies Consulting Group, an independent valuation approved by the Company and Parent (the “Valuation Firm”). All Parent Shares converted to cash pursuant to this Section 1.6(c) shall be treated as cancelled and treated as authorized and unissued Parent Shares.

(d) Company Options. At the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Merger Sub or the Company, each option to purchase shares of the Company’s Common Stock outstanding immediately prior to the Effective Time (the “Company Options”) shall be treated as follows:

(i) each Company Option will be assumed by Parent (an “Assumed Option”). Each Assumed Option will continue to have, and be subject to, the same terms and conditions of such option immediately prior to the Effective Time, including the vesting conditions, except that (1) each Assumed Option will be exercisable for that number of Parent Shares equal to the number of shares of Company

-3-

Common Stock subject to the Assumed Option immediately prior to the Effective Time multiplied by the Company Option Exchange Rate, with the resulting share amounts rounded down to the nearest whole number of shares, (2) the per share exercise price for the Parent Shares issuable upon exercise of the Assumed Option shall be equal to the quotient obtained by dividing (x) the exercise price per share of Company Common Stock at which such Assumed Option was exercisable immediately prior to the Effective Time by (y) the Company Option Exchange Rate, rounded up to the nearest whole cent, and (3) all references to the “Company” in the Stock Plan and the stock option agreements will be references to Parent. The “Company Option Exchange Rate” shall mean (x) the fair value of all consideration (including the estimated Escrow Shares and the Earnout Amount) payable under this Agreement per share of Company Common Stock outstanding immediately prior to the Effective Time, as determined by the Valuation Firm prior to closing, assuming exercise of all Company Options and other rights to acquire Company Common Stock immediately prior to the Effective Time, which is expected to be approximately $0.4749 per share, divided by (y) $2.55, the fair value of a single Parent Share as of the Effective Date. It is the intention of the parties that each Company Option so assumed shall be assumed and converted in a manner that satisfies the requirements of Treasury Regulation § 1.409A-1(b)(5)(v)(D) so as not to be treated as the grant of a new stock right or change in the form of payment for purposes of Treasury Regulations §§ 1.409A-1 through 1.409A-6. In the case of any Company Option to which Section 421 of the Code applies as of the Effective Time by reason of its qualification under Section 422 of the Code, the exercise price, the number of shares subject to such option and the terms and conditions of exercise of such option shall be determined in a manner consistent with the requirements of Section 424(a) of the Code.

(ii) Prior to the Effective Time, the Company shall provide notice (in a form reasonably satisfactory to Parent) to each holder of a Company Option describing the treatment of such options in accordance with this Section 1.6(d) and shall obtain a signed written consent to such treatment from each holder of a Company Option, in a form reasonably acceptable to Parent (the “Company Optionholder Consent”).

(e) Merger Sub Capital Stock. At the Effective Time, each share of Common Stock, par value $0.001 per share, of Merger Sub (“Merger Sub Common Stock”) issued and outstanding immediately prior to the Effective Time shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into one share of common stock, par value $0.001 per share, of the Surviving Corporation (the “Surviving Corporation Common Stock”).

(f) Fractional Shares. No fraction of a Parent Share will be issued in the Merger. After aggregating all fractional Parent Shares to be received by any Person all remaining fractional Parent Shares that would have been issued in the Merger shall be rounded down to the nearest whole share thereof and such Person shall be entitled to receive in lieu of such fractional share an amount of cash (rounded down to the nearest whole cent) equal to the product of (i) such fraction, multiplied by (ii) the fair market value of one Parent Share on the Closing Date.

(g) Dissenting Shares.

(i) Notwithstanding anything in this Agreement to the contrary and unless otherwise provided by applicable law, shares of Company Capital Stock that are issued and outstanding immediately prior to the Effective Time and that are owned by stockholders who have properly perfected their appraisal rights in accordance with applicable law (“Dissenting Shares”) will not be converted into the right to receive Merger Consideration, unless and until such stockholders will have failed to perfect or will have effectively withdrawn or lost their right of payment under applicable law. Such stockholders, who have so perfected their appraisal rights, will instead be entitled to payment of the fair value of such Dissenting Shares in accordance with applicable law. If any such stockholder will have failed to perfect or will have effectively

-4-

withdrawn or lost such appraisal rights, each share of Company Capital Stock held by such stockholder will thereupon be deemed to have been converted into the right to receive and become exchangeable for, at the Effective Time, the Merger Consideration specified and allocated in Section 1.6(a), (b) or (c), as applicable and subject to the terms thereof.

(ii) The Company will give Parent prompt notice of any demands for appraisal received by the Company, withdrawals of such demands and any other instruments served in connection with such demands and received by the Company or its representatives, and the opportunity to direct all negotiations and proceedings with respect to such demands consistent with the Company’s obligations thereunder. The Company will not, except with the prior written consent of Parent, voluntarily make any payment, admission or statement against interest with respect to any such objection, offer to settle or settle any such objection or waive any failure by a former Company stockholder to timely deliver a written objection or to perform any other act perfecting appraisal rights in accordance with applicable law.

(h) Parent Financing Agreements. As a condition to the issuance of Parent Shares to Company stockholders pursuant to this Agreement, Company stockholders receiving Parent Shares or rights to Parent Shares shall execute the Joinder to become party to the Parent Sixth Amended and Restated Investors’ Rights Agreement dated July 1, 2009, as amended, the Parent Fourth Amended & Restated Right of First Refusal and Co-Sale Agreement dated July 1, 2009, as amended, and the Parent Third Amended and Restated Voting Agreement dated July 1, 2009, as amended, in the forms provided by Parent to the Company (the “Parent Financing Agreements”). The Parent Investors Rights Agreement shall be amended to provide all holders of Company Common Stock who receive Parent Shares pursuant to this Agreement with the preemptive rights or rights of first refusal set forth in Section 3 of the Investors Rights Agreement whether they meet the definition of Major Investor set forth therein or not. Subsequent to the Effective Time, the Holders’ Agent shall be permitted to appoint a board observer to Parent’s board of directors on behalf the Indemnifying Securityholders, which board observer will have customary board observer rights from and after the Effective Time until such time as Parent closes a firm commitment underwritten public offering in which Parent has raised at least thirty million dollars ($30,000,000), subject to the board observer entering into the observer rights letter in the form attached hereto as Exhibit F. The individual selected by the Holders’ Agent to serve as the board observer shall be reasonably acceptable to Parent, and shall initially be Xxxxxxx Xxxxx. If the observer is not already party to a confidentiality agreement with the Company, the observer shall execute a confidentiality agreement on terms and conditions consistent with the Mutual Confidentiality Agreement.

(i) Taking of Necessary Further Actions. Each of Parent, the Company and the Holder’s Agent will take all such reasonable and lawful action as may be necessary or appropriate in order to effectuate the Merger in accordance with this Agreement as promptly as possible. If, at any time after the Effective Time, any such further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of the Company, the officers and directors of the Company immediately prior to the Effective Time are and will remain fully authorized in the name of the Company or otherwise to take, and will take, upon request by Parent, all such lawful and necessary action.

1.7 Closing Date Balance; Calculation and Payment of Per Share Cash Amounts.

(a) At least two (2) Business Days prior to the Closing Date, the Company shall prepare and deliver to Parent and the Holders’ Agent a statement of the estimated Closing Date Balance (“Estimated Closing Date Balance Statement”) showing the Company’s estimate of current assets, including Company cash and cash equivalents and Company Liabilities as of the Effective Time. The Company shall provide Parent and its accounting and financial staff, auditors and advisors reasonable access to the books and records

-5-

of the Company and its accounting and financial staff in connection with Parent’s review thereof. The Company will review any comments on the Estimated Closing Date Balance Statement made by Parent and will consider, in good faith, any appropriate changes. The Company will calculate the Company Surplus Cash distributed under Section 1.4 to ensure that the Estimated Closing Date Balance, after giving effect to the distribution of the Company Surplus Cash, is equal to or greater than zero.

(b) Following the Closing Date, Parent shall prepare and deliver to the Holders’ Agent, as soon as reasonably practicable but in no event later than one hundred twenty (120) days following the Closing Date, a “Closing Date Balance Statement” detailing the current assets, including Company cash and cash equivalents, and Company Liabilities as of the Effective Time.

(c) The Holders’ Agent shall have thirty (30) days from its receipt of the Closing Date Balance Statement (the “Objection Period”) to review the Closing Date Balance Statement. Parent shall grant the Holders’ Agent access at reasonable times and places and upon reasonable advance notice to all books, records and employees of the Surviving Corporation as reasonably requested by the Holders’ Agent in connection with its review of the Closing Date Balance Statement and shall reasonably answer inquiries from the Holders’ Agent related thereto. Upon the expiration of the Objection Period, the Holders’ Agent, on behalf of all Company Stockholders, shall be deemed to have accepted, and shall be bound by, the Closing Date Balance Statement, unless the Holders’ Agent shall have informed Parent in writing of its disagreement with the Closing Date Balance Statement prior to the expiration of the Objection Period (the “Objection”), specifying each disputed item and setting forth in reasonable detail the basis for each such dispute (each, a “Disputed Item”). Parent shall have fifteen (15) days from the date on which it receives the Objection (the date on which such fifteen (15) day period ends, the “Response Date”) to review and respond to such Objection. If Parent and the Holders’ Agent are able to negotiate a mutually agreeable resolution of each Disputed Item, and each signs a certificate to that effect, the Closing Date Balance Statement, as adjusted to reflect such resolution, shall be deemed final, non-appealable and binding for purposes of this Agreement. If any Disputed Items have not been resolved by the Response Date, either Parent or the Holders’ Agent may refer such Disputed Items to an independent, mutually agreeable, public accounting firm (the “Accounting Referee”) to make a final, non-appealable and binding determination as to such remaining Disputed Items pursuant to the terms hereof. The Accounting Referee shall be directed to make a determination in accordance with Section 1.7(d) of the Disputed Items promptly, but no later than thirty (30) days, after acceptance of its appointment. Parent and the Holders’ Agent agree to use their commercially reasonable efforts to effect the selection and appointment of the Accounting Referee pursuant to this Section 1.7(c), including executing an engagement agreement with the Accounting Referee providing for reasonable and customary compensation and other terms of such engagement. Parent and the Holders’ Agent shall make readily available to the Accounting Referee all relevant books, records and employees of the Company and the Surviving Corporation that are reasonably requested by the Accounting Referee in connection with the Accounting Referee’s review of any Disputed Items.

(d) If Disputed Items are referred to the Accounting Referee for resolution, the Accounting Referee shall determine only with respect to the Disputed Items submitted whether and to what extent, if any, each Disputed Item the Closing Date Balance Statement is to be adjusted and each such adjustment shall be no greater than the higher amount calculated by Parent or the Holders’ Agent, as the case may be, and no lower than the lower amount calculated by Parent or the Holders’ Agent, as the case may be. Any finding by the Accounting Referee shall be a reasoned award stating in reasonable detail the findings of fact on which it is based, shall be final, non-appealable and binding upon the parties hereto and shall be the sole and exclusive remedy between the parties hereto regarding the Disputed Items so presented. The fees and expenses of the Accounting Referee shall be borne by Parent and the Company Stockholders in the same proportion that the dollar amount of Disputed Items which are not resolved in favor of Parent or the Company Stockholders, as applicable, bears to the total dollar amount of Disputed Items resolved by the Accounting

-6-

Referee. Each of Parent, the Holders’ Agent and the Company Stockholders shall bear the fees, costs and expenses of its own accountants and all of its other expenses incurred in connection with matters contemplated by this Section 1.7.

(e) Payments.

(i) Payment of the adjustments as contemplated by this Section 1.7(e) shall be made (A) if no Objection is made by the Holders’ Agent during the Objection Period, within fifteen (15) Business Days following the expiration of the Objection Period or (B) if the Holders’ Agent submits an Objection within the Objection Period, within fifteen (15) Business Days following final resolution of all Disputed Items by either Parent and the Holders’ Agent or the Accounting Referee.

(ii) If, upon the final determination, the Closing Date Balance Statement shows a positive Closing Date Balance, such amount shall be added to the Cash Payment Amount. If the Closing Date Balance Statement shows a negative Closing Date Balance, such amount shall be subtracted from the Cash Payment Amount. If the Closing Date Balance is still negative after applying the Cash Payment Amount, the Excess Closing Date Balance Shortfall shall be paid to Parent by Newco in cash and if Newco does not make such payment within thirty (30) days of written notice to Newco, then such Excess Closing Date Balance Shortfall shall be satisfied from the Escrow Amount.

(iii) Within ten (10) days following determination of the Cash Payment Amount in accordance with this Section 1.7(e), Parent shall pay Newco the Cash Payment Amount, if any, pursuant to the Asset Transfer Agreement.

1.8 Escrow. At Closing, 520,253 Parent Shares (the “Escrow Shares”) shall be available to Parent as security for the indemnification claims of the Parent Indemnified Parties and shall be released in accordance with Section 7.5(c).

1.9 Earnout Consideration.

(a) Earnout Amount. The Earnout Amount is 1,560,760 Parent Shares (the “Earnout Amount”). The Earnout Amount shall be earned when Parent or its Affiliates or a Licensee, acquirer or other transferee of Parent (collectively “Milestone Obligors”) complete an aggregate of two thousand five hundred (2,500) Commercial Tests in the United States no later than six (6) years after the Closing Date (“Earnout Milestone”). Subject to the preceding sentence, Parent shall pay the Earnout Amount by issuing such shares and then distributing such shares in accordance with Sections 1.6 and 1.10. Parent shall cause such distribution to occur within thirty (30) days of the date the Earnout Amount is earned (the “Earnout Amount Payment Date”). The Earnout Amount will be subject to set-off or reduction for payment of Losses determined to be owed to the Parent Indemnified Parties that are otherwise payable pursuant to Section 7.3(b)(y)(ii) (and the limitations set forth therein) prior to the Earnout Amount Payment Date.

(b) Information. Commencing upon the Closing and until the Earnout Amount Payment Date, Parent shall provide, on a quarterly basis, a written report to the Holders’ Agent, signed by an officer of Parent, in reasonable detail regarding the status of efforts to achieve the Earnout Milestone (each such report, an “Update Report”). If after delivery of an Update Report, the Holders’ Agent requests in writing a meeting with representatives of Parent to discuss such report, Parent shall make available in person or by phone for such a meeting appropriate representative(s) involved (including employees of Parent or its Affiliates who are responsible for managing the research, development and commercialization activities with respect to Commercial Tests) in the applicable activities set forth in the Update Report; provided, however, that, for the avoidance of doubt, at any such meeting, other representatives (including counsel and advisors) of

Until the Escrow Expiration Date, no delay on the part of a Company Indemnified Party in delivering a Notice of Claim with respect to claims under Section 7.2(b) for breach of Company representations and warranties that are not Fundamental Company Representations shall relieve any Indemnifying Securityholder (each an “Indemnifying Party”) from any of its respective obligations under this Article VII unless (and then only to the extent that) the Indemnifying Party is prejudiced thereby.

(b) Objections to Claims. Within thirty (30) days after receipt of a Notice of Claim, the Holders’ Agent may object in a written statement signed by an officer of the Holders’ Agent to any Claim made in the Notice of Claim. Upon reasonable notice, the Parent shall, and shall cause the Surviving Corporation to, afford the Holders’ Agent and its accountants, counsel and other representatives, reasonable access during normal business hours during the period from the receipt of a Notice of Claim until the final resolution of the matters set forth therein, provided, in each case, that such access does not cause material disruption to the day-to-day operation of the Surviving Corporation or Parent, as the case may be, to all information relating to the matters set forth in such Notice of Claim as may be reasonably requested.

7.7 Resolution of Conflicts; Arbitration.

(a) Resolution of Conflicts. The Holders’ Agent and a representative of the Parent Indemnified Party shall attempt in good faith for thirty (30) days to agree upon the rights of the respective parties with respect to the Claim. If the Holders’ Agent and such Parent Indemnified Party should so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties and such Claim shall be deemed to be resolved.

-47-

(b) Arbitration. If no such agreement can be reached after good faith negotiation, either Parent or the Holders’ Agent, as applicable, may, by written notice to the other, demand arbitration of the matter unless the amount of the damage or loss is at issue in pending litigation with a third party, in which event arbitration shall not be commenced until such amount is ascertained or both parties agree to arbitration; and in either such event the matter shall be settled by arbitration conducted by one (1) independent arbitrator as mutually agreed upon by Parent and the Holders’ Agent, as applicable. In the event that within ten (10) days after submission of any dispute to arbitration, Parent and the Holders’ Agent cannot mutually agree on one (1) arbitrator, Parent and the Holders’ Agent shall each select one (1) arbitrator, and the two (2) arbitrators so selected shall select a third (3rd) arbitrator no later than fifteen (15) days after submission of any dispute to arbitration. The arbitration shall be administered by and in accordance with the then-existing Rules of Practice and Procedure of JAMS/Endispute. Notwithstanding anything to the contrary contained herein, the arbitrator (or arbitrators) shall apply and follow all applicable legal requirements in making his or her decision. The decision of the arbitrator (or arbitrators) as to the validity and amount of the disputed Claim shall be binding and conclusive upon the parties to this Agreement (and not subject to appeal), Parent shall be entitled to act in accordance with such decision and make, withhold or distribute payments out of the Escrow in accordance therewith.

(c) Judgment upon any award rendered by the arbitrators may be entered in any court having jurisdiction. For purposes of this Section 7.7(c), in any arbitration hereunder in which the amount thereof stated in the Notice of Claim is at issue, the Indemnified Party shall be deemed to be the non-prevailing party, unless the arbitrators award such Parent Indemnified Party more than one-half (1/2) of the amount in dispute; in which case, the Indemnifying Parties shall be deemed to be the non-prevailing party. The non-prevailing party to an arbitration proceeding shall pay its own expenses, the fees of each arbitrator, the administrative fee of JAMS/Endispute and the reasonable expenses, including without limitation, reasonable attorneys’ fees and costs, reasonably incurred by the other party to the arbitration. If the applicable Indemnifying Parties are deemed to be the non-prevailing party, such expenses and fees shall be paid first, from the Escrow Shares held in the Escrow (to the extent that such Escrow Shares are not otherwise required to satisfy any Company Losses), and second, by the Indemnifying Party.

7.8 Holders’ Agent.

(a) Effective as of the Effective Time, Xxxxxxx Xxxxxxx (the “Holders’ Agent”), is hereby appointed, authorized and empowered by Company to act as the agent of, and attorney-in-fact for, and on behalf of the Indemnifying Securityholders in connection with, and to facilitate the consummation of the transactions contemplated by, this Agreement, and in connection with the activities to be performed on behalf of the Indemnifying Securityholders collectively, and each of them individually, under this Agreement, for the purposes and with the powers and authority hereinafter set forth in this Section 7.8, which shall include the full power and authority:

-49-

The Holders’ Agent has only the duties expressly stated in this Agreement, and shall have no other duty, express or implied. The Holders’ Agent is not, nor shall the Holders’ Agent be deemed, a fiduciary of the Indemnifying Securityholders in any capacity or for any purpose.

(b) By virtue of their approval of the Merger and this Agreement, each of the Indemnifying Securityholders shall be deemed to have appointed Xxxxxxx Xxxxxxx, as the Holders’ Agent for all purposes set forth in this Section 7.8.

(c) The Holders’ Agent shall have no responsibility or liability for any representation, warranty or covenant of Company, the Indemnifying Securityholders, or the Merger Sub. The Holders’ Agent shall not be liable for any act done or omitted to be done as Holders’ Agent while acting in good faith and in the exercise of reasonable judgment. The Holders’ Agent shall, in no case or event, be liable to any Indemnifying Securityholder for any punitive, incidental or consequential damages. Without limiting the generality of the foregoing, the Holders’ Agent shall not be liable for forgeries or false impersonations by any other person. The Indemnifying Securityholders shall severally indemnify the Holders’ Agent and hold it harmless against any loss, liability or expense incurred without gross negligence or bad faith on the part of such Holders’ Agent and arising out of or in connection with the acceptance or administration of its duties hereunder, including expenses of any legal counsel retained by the Holders’ Agent (“Agent Losses”). The Holders’ Agent shall have the right to recover any Agent Losses from the Agent Fund (as defined below) as such expenses arise and, to the extent that the Agent Fund has been depleted, if then available after satisfaction of all claims of Parent Indemnified Parties, the Holders’ Agent shall have the right to recover Agent Losses from the Escrow prior to the final distribution to the Indemnifying Securityholders, and prior to any such distribution, the Holders’ Agent shall deliver to Parent a certificate setting forth the Agent Losses actually incurred. In the event that the Agent Fund is exhausted and the Escrow is unavailable, the Indemnifying Securityholders shall be jointly and severally responsible for (i) the payment of all fees and expenses reasonably incurred by the Holders’ Agent in performing its duties under this Agreement, and (ii) any Agent Losses (together, (i) and (ii) above are “Excess Fees and Losses”); and each Indemnifying Securityholder shall promptly deliver to the Holders’ Agent full payment of his, her or its pro rata portion of such Excess Fees and Losses. This Section 7.8(c) shall survive the termination of this Agreement.

(d) Immediately prior to the Effective Time, Company shall deposit into an account designated by the Holders’ Agent an amount equal to one hundred and fifty thousand dollars ($150,000) (the “Agent Fund”). Any out-of-pocket costs and expenses reasonably incurred by the Holders’ Agent in connection with actions taken by the Holders’ Agent pursuant to the terms of this Section 7.9 (including the hiring of legal counsel and the incurring of reasonable legal fees and costs) and any Holders’ Agent Losses will be paid to the Holders’ Agent from the Agent Fund, and the Holders’ Agent may use the Agent Fund only to pay such costs and expenses reasonably incurred and to satisfy any Holders’ Agent Losses. The Holders’ Agent shall keep the Agent Fund segregated from all other funds, and shall not comingle in any way the Agent Fund with any other funds. Promptly after the Holders’ Agent determines, in its sole discretion, that additional costs and expenses reasonably incurred by the Holders’ Agent are not reasonably foreseeable, the Holders’ Agent shall deliver any and all amounts remaining in the Agent Fund to Newco.

(e) Parent shall provide the Holders’ Agent with reasonable access to information about Parent and Company and the reasonable assistance of the Surviving Corporation’s, and Parent’s officers, directors and employees for purposes of performing its duties and exercising its rights hereunder, provided that, any information received by the Holders’ Agent in performing his or her duties and exercising rights hereunder shall constitute confidential “Information” pursuant to the Mutual Confidentiality Agreement and the Holders’ Agent hereby agrees to be bound to such Mutual Confidentiality Agreement as if it were a party thereto with respect to any such information; provided, that, notwithstanding the foregoing, the Holders’ Agent may disclose such information to individuals and experts engaged pursuant to Section 7.8(g) below who agree to treat such information confidentially, and Indemnifying Securityholders that have signed a substantially similar confidentiality agreement in favor of Parent.

-50-

(f) Xxxxxxx Xxxxxxx hereby agrees to act as the Holders’ Agent pursuant to the terms of this Agreement and a Representation Agreement entered into on or before the Effective Time by and among Company, the Holders’ Agent and certain Indemnifying Securityholders.

(g) The Holders’ Agent may engage attorneys, accountants and other professionals and experts. The Holders’ Agent may in good faith rely conclusively on information, reports, statements, opinions, including financial statements, about Company, the Surviving Corporation, or another person, that were prepared or presented by (i) one or more officers or employees of Company, or the Surviving Corporation, or (ii) legal counsel, public accountants, investment bankers or other persons as to matters the Holders’ Agent believes in good faith are within the person’s knowledge, professional or expert competence. Any action taken by Holders’ Agent based on such reliance shall be deemed conclusively to have been taken in good faith and in full satisfaction of such Holders’ Agent’s duties under this Agreement.

(h) The Holders’ Agent may resign or such agency may be changed by the Indemnifying Securityholders from time to time upon not less than ten (10) days prior written notice to Parent, and the Surviving Corporation; provided, however, that the Holders’ Agent may not be removed unless holders entitled to at least 66-2/3% of the Parent Shares issued at any given time pursuant to Section 1.6 agree to such removal and to the identity of the substituted agent (voting on the basis of the number of Parent Shares to which such holders are entitled and not on a holder-by-holder basis). Notwithstanding the foregoing, a vacancy in the position of the Holders’ Agent may be filled by the holders of a majority of the Company capital stock outstanding immediately prior to the Effective Time.

7.9 Actions of Holders’ Agent. A decision, act, consent or instruction of the Holders’ Agent shall constitute a decision of all Indemnifying Securityholders and shall be final, binding and conclusive upon each such Indemnifying Securityholder, and any Parent Indemnified Party may rely upon any decision, act, consent or instruction of the Holders’ Agent as being the decision, act, consent or instruction of each and every such Indemnifying Securityholders. To the extent that a Parent Indemnified Party acts in accordance with a decision, act, consent or instruction of the Holders’ Agent, such Parent Indemnified Party is hereby relieved from any liability with respect to such act, to any Person, including the Indemnifying Securityholders.

7.10 Third Party Claims.

(a) In the event that a Parent Indemnified Party becomes aware of a third party claim (a “Third Party Claim”) that Parent Indemnified Party reasonably believes may result in a Claim against an Escrow, such Parent Indemnified Party shall promptly notify the Holders’ Agent of such Third Party Claim. If a Third Party Claim does not seek any equitable relief or relief other than the payment of money damages in an amount not in excess of the amount of the applicable Escrow as to which no Unresolved Claims are pending, and if Holders’ Agent acknowledges in writing the Parent Indemnified Party’s right to reimbursement and indemnification hereunder out of the Escrow for Company Losses with respect to such Third Party Claim if the underlying allegations are determined to be true, then the Holders’ Agent may, at its election, undertake and conduct the defense of such Third Party Claim at its sole cost and expense. Parent shall be entitled, at its sole cost and expense, to participate in, but not to determine or conduct, the defense of such Third Party Claim, and the Holders’ Agent shall consult with Parent regarding the strategy for defense of such claim.

-51-

(b) If Holders’ Agent does not so elect to undertake and conduct the defense of such Third Party Claim, Parent shall undertake the defense of and use reasonable efforts to defend such Third Party Claim and shall consult with the Holders’ Agent regarding the strategy for defense thereof.

(c) In the event that the Holders’ Agent shall exercise its right to undertake any such defense against any such Third Party Claim, Parent shall cooperate with the Holders’ Agent in such defense and make available to the Holders’ Agent all witnesses, pertinent records, materials and information in Parent’s possession or under Parent’s control relating thereto as is reasonably requested by the Holders’ Agent. Similarly, in the event Parent is, directly or indirectly, controlling or participating in the defense against any such Third Party Claim, the Holders’ Agent shall cooperate with Parent in such defense and make available to Parent, all such witnesses, records, materials and information in the Holders’ Agent’s possession or under its control relating thereto as is reasonably requested by such Parent Indemnified Party.

(d) In the event that Parent has undertaken the defense of a Third Party Claim, Parent will have the right in its sole discretion to settle such Third Party Claim; provided, however, that, without the consent of the Holders’ Agent, any such settlement by Parent of a Third Party Claim will not be determinative as to any liability hereunder or the amount of Company Indemnifiable Losses relating to such matter. If Holders’ Agent does consent to any such settlement, the Holders’ Agent will not have any power or authority to object to the amount or validity of any claim by or on behalf of any Parent Indemnified Party for indemnity with respect to such settlement. No Third Party Claim may be settled by the Holders’ Agent without the prior written consent of Parent, or the applicable Parent Indemnified Party, as the case may be, unless the settlement provides solely for the payment of money, the Indemnifying Securityholders make such payment (subject to the applicable limitations contained in this Agreement) and Parent, or the applicable Parent Indemnified Party, as the case may be, receives an unconditional release.

7.11 Voting Rights and Cash Distributions With Respect to Escrow Shares.

(a) The Escrow Shares shall be issued at Closing to the Escrow Agent and held by Escrow Agent as nominee for the Indemnifying Securityholders in accordance with an escrow agreement in form mutually agreed by Parent and the Company (the “Escrow Agreement”), and the Indemnifying Securityholders shall have all voting rights in and rights to all dividends in respect of the Escrow Shares other than with respect to Escrow Shares forfeited to Parent in accordance with this Article VII.

(b) Any shares of Parent capital stock received pursuant to a stock split made in respect of any securities in the Escrow shall be added to the respective Escrow and become a part thereof. The provisions of Article VII shall be adjusted to appropriately reflect any stock split or reverse stock split.

(iv) within two (2) Business Days from the time of the execution and delivery of this Agreement by all of the parties hereto, stockholders of the non-terminating party (Parent or Company, as the case may be) have not duly adopted and approved this Agreement and the Merger in accordance with the DGCL and the Certificate of Incorporation of the non-terminating party.

The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

9.3 Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties, it being understood that all parties need not sign the same counterpart.

9.4 Schedules and Exhibits. All references to Schedules and Exhibits herein, unless otherwise stated, mean the schedules and exhibits attached to this Agreement.

9.5 Entire Agreement; Nonassignability; Parties in Interest. This Agreement and the documents and instruments and other agreements specifically referred to herein or delivered pursuant hereto, including the Exhibits, Schedules and Parent Disclosure Document and Company Disclosure Document: (a) constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof, except the Mutual Confidentiality Agreement, which shall continue in full force and effect, and shall survive any termination of this Agreement or the Closing, in accordance with its terms; (b) shall not be assigned by operation of law or otherwise without the prior written consent of the other parties; and (c) are not intended to create any third party beneficiaries, except as expressly provided in Article VII and Section 4.9.

-55-

9.7 Specific Performance. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity.

9.8 Governing Law. This Agreement shall be governed by and construed and enforced in accordance with the laws of the State of Delaware, without regard to its principles of conflicts of law.

9.9 Rules of Construction. The parties hereto agree that they have been represented by counsel during the negotiation, preparation and execution of this Agreement and, therefore, waive the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.

9.10 Ownership of Attorney-Client Privilege. The Indemnifying Securityholders, the Company and the Holders’ Agent (collectively, the “Company Parties”) have received representation from counsel (“Counsel”) in connection with this Agreement and the transactions contemplated hereby and thereby (the “Acquisition Engagement”). To the extent that communications between a Company Party, on the one hand, and Counsel, on the other hand, relate to the Acquisition Engagement, such communication shall be deemed to be attorney-client confidences that belong solely to the Holders’ Agent, for and on behalf of the Indemnifying Securityholders, and not the Company or Surviving Corporation. Neither Parent nor any of its Affiliates, including the Surviving Corporation, shall have access to (and Parent hereby waives, on behalf of each, any right of access it may otherwise have with respect to) any such communications or the files or work product of Counsel, to the extent that they relate to the Acquisition Engagement, whether or not the Closing occurs. Without limiting the generality of the foregoing, Parent acknowledges and agrees, for itself and on behalf of its Affiliates, including the Surviving Corporation, upon and after the Closing: (i) the Holders’ Agent, for and on behalf of the Indemnifying Securityholders, and Counsel shall be the sole holders of the attorney-client privilege with respect to the Acquisition Engagement, and neither Parent nor any of its Affiliates, including the Surviving Corporation, shall be a holder thereof; (ii) to the extent that files or work product of Counsel in respect of the Acquisition Engagement constitute property of the client, only the Holders’ Agent, for and on behalf of the Indemnifying Securityholders, shall hold such property rights and have the right to waive or modify such property rights; and (iii) Counsel shall have no duty whatsoever to reveal or disclose any such attorney-client communications, files or work product to Parent or any of its Affiliates, including the Surviving Corporation, by reason of any attorney-client relationship between Counsel and the Company or otherwise; provided that, to the extent any communication is both related and unrelated to the Acquisition Engagement, Counsel shall provide (and the Holders’ Agent, for and on behalf of the Indemnifying Parties, shall instruct Counsel to provide) appropriately redacted versions of such communications, files or work product to Parent or its Affiliates, including the Surviving Corporation. Notwithstanding and without limiting the foregoing, in the event that a dispute arises between any of Parent or the Surviving Corporation or their Affiliates, on one hand, and any of the Indemnifying Securityholders or Holders’ Agent (on behalf of the Indemnifying Securityholders), on the other hand, concerning the matters contemplated in this Agreement, Parent, for itself and on behalf of its Affiliates and the Surviving Corporation and its Affiliates, agrees that Parent, the Surviving Corporation and their Affiliates shall not offer into evidence or otherwise attempt to use or assert the foregoing attorney-client communications, files or work product against the Holders’ Agent or the Indemnifying Securityholders.

9.11 Waiver of Jury Trial. EACH OF PARENT, MERGER SUB AND COMPANY HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF

In the case of all other Taxes, the Taxes shall be apportioned between Newco and Company based on an interim closing of the books at the end of the Closing Date, except that exemptions, allowances, or deductions that are calculated on an annual basis, other than with respect to property placed into service after the ATA Closing, shall be allocated on a per diem basis. The Party required by Applicable Law to file such a tax return (the “Paying Party”) shall file the Tax Return related to such Straddle Period Tax within the time period prescribed by Applicable Law and shall timely pay such Straddle Period Tax.

ARTICLE VI

INDEMNIFICATION

6.1 Indemnification by the Company. The Company shall indemnify and hold harmless Newco and its Affiliates, officers, directors, employees, agents, successors and assigns (each, a “Newco Indemnified Party”) from and against any and all liabilities, losses, damages, costs and expenses, interest, awards, judgments and penalties (including, without limitation, reasonable attorneys’ fees and expenses) (collectively, “Losses”) suffered or incurred by them arising out of or resulting from the following:

(a) the breach of any covenant or agreement by the Company contained in this Agreement solely to the extent that such Losses are incurred as a result of Third Party Claims made against a Newco Indemnified Party; or

(b) the Retained Liabilities solely to the extent that such Losses are (A) incurred as a result of Third Party Claims made against a Newco Indemnified Party with respect to such Retained Liability or (B) directly incurred by Newco as a result of Newco’s fulfillment of the Company’s obligations under any Retained Liability in the event that such fulfillment is reasonably required for Newco to maintain or exercise the rights granted to it under this Agreement.

6.2 Indemnification by Newco. Newco shall indemnify and hold harmless the Company and its Affiliates, officers, directors, employees, agents, successors and assigns (each a “Company Indemnified Party”) from and against any and all Losses suffered or incurred by them arising out of or resulting from the following:

(a) the breach of any covenant or agreement by Newco contained in this Agreement solely to the extent that such Losses are incurred as a result of Third Party Claims made against a Company Indemnified Party; or

(b) the Assumed Liabilities solely to the extent that such Losses are incurred as a result of Third Party Claims made against a Company Indemnified Party with respect to such Assumed Liability.

6.3 Indemnification Procedure.

(a) Whenever any Loss is asserted against or incurred by a Newco Indemnified Party or Company Indemnified Party (the “Indemnified Party”) which the Indemnified Party has determined has given or could give rise to a right of indemnification under this Agreement, the Indemnified Party will give written notice thereof (a “Claim”) to the other Party (the “Indemnifying Party”). The Indemnified Party will furnish to the Indemnifying Party in reasonable detail such

-22-

information as the Indemnified Party may have with respect to the Claim. The failure to give such notice will not relieve the Indemnifying Party of its indemnification obligations under this Agreement, unless the failure to give such notice is materially prejudicial to an Indemnifying Party’s ability to defend an action by a Third Party giving rise to such Claim (a “Third Party Claim”).

(b) In the case of a Third Party Claim, within thirty (30) days after delivery of such notice, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, and at its expense, undertake the defense of such Third Party Claim with attorneys of its own choosing. In the event that the Indemnifying Party does not assume control of such defense, the Indemnified Party may undertake the defense of such Third Party Claim.

(c) The Party not controlling such defense may participate therein at its own expense, provided that if the Indemnifying Party assumes control of such defense and the Indemnified Party reasonably concludes, based on advice from counsel, that the Indemnifying Party and the Indemnified Party have conflicting interests with respect to such action, suit, proceeding or claim, the Indemnifying Party will be responsible for the reasonable fees and expenses of counsel to the Indemnified Party solely in connection therewith, provided further, however, that in no event will the Indemnifying Party be responsible for the fees and expenses of more than one counsel in any one jurisdiction for all Indemnified Parties.

(d) The Party controlling such defense will keep the other Party advised of the status of such action, suit, proceeding or claim and the defense thereof and will consider recommendations made by the other Party with respect thereto. As reasonably requested by, and at the expense of, the Party controlling such defense, the other Party will cooperate in such defense and make available to the Party controlling such defense all witnesses, pertinent records, materials and information in such other Party’s possession or under such other Party’s control relating thereto.

(e) The Indemnified Party will not agree to any settlement of such action, suit, proceeding or claim without the prior written consent of the Indemnifying Party, which will not be unreasonably withheld or delayed. The Indemnifying Party will not consent to entry of any judgment or enter into any settlement that admits fault on the part of the Indemnified Party, except with the prior written consent of the Indemnified Party, which consent will not be unreasonably withheld or delayed. In the event that the Indemnified Party refuses to consent to the entry of a judgment or a settlement for which the Indemnifying Party is solely and entirely responsible and has indicated its sole and entire responsibility in writing to the Indemnified Party, following such refusal, the liability of the Indemnifying Party to the Indemnified Party will be fixed at the amount of any money damages provided in the proposed judgment or settlement.

6.4 Limitations on Indemnification.

(a) UNDER NO CIRCUMSTANCES WILL A PARTY BE LIABLE TO THE OTHER PARTY FOR LOST PROFITS, LOST OPPORTUNITIES, OR ANY OTHER PUNITIVE, SPECIAL, OR CONSEQUENTIAL DAMAGES IRRESPECTIVE OF THE THEORY UNDER WHICH SUCH ACTION IS BROUGHT, WHETHER IT WAS CAUSED OR ALLEGEDLY CAUSED BY THE NEGLIGENCE OF SUCH PARTY OR WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

-23-

(b) Notwithstanding anything to the contrary in this Agreement, the Merger Agreements or the Transaction Documents, the indemnification rights set forth in this ARTICLE VI shall be the sole and exclusive remedy of the Indemnified Parties from and after the ATA Closing for any claims arising under or related to this Agreement, including any claims relating to the Transferred Assets, Assumed Liabilities and Retained Liabilities.

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, and the application of such provision to other persons or circumstances other than those as to which it is determined to be illegal, void or unenforceable, will not be impaired or otherwise affected and will continue in full force and effect and be enforceable to the fullest extent permitted by Applicable Law.

7.5 Remedies Cumulative. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with, and not exclusive of, any other remedy conferred hereby, or by Applicable Law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy.

7.6 Governing Law. This Agreement shall be governed by and construed in accordance with the internal Applicable Laws of the State of Delaware applicable to parties residing in the State of Delaware, without regard to applicable principles of conflicts of law. Each of the parties irrevocably consents to the exclusive jurisdiction and venue of any Delaware State court, or Federal court of the United States of America, sitting in Delaware, and any appellate court from any thereof, in connection with any matter based upon or arising out of this Agreement or the transactions contemplated hereby and agrees that process may be served upon it in any manner authorized by the Applicable Laws of the State of Delaware for such persons and waives and covenants not to assert or plead any objection which it might otherwise have to such jurisdiction and such process. Each of the parties irrevocably waives the right to trial by jury in connection with any matter based upon or arising out of this Agreement or the transactions contemplated hereby.

7.7 Rules of Construction.

(a) The parties hereto agree that they have been represented by counsel during the negotiation, preparation and execution of this Agreement and, therefore, waive the application of any Applicable Law, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.

-25-

(b) For purposes of this Agreement, whenever the context requires: the singular number shall include the plural, and vice versa; the masculine gender shall include the feminine and neuter genders; the feminine gender shall include the masculine and neuter genders; and the neuter gender shall include the masculine and feminine genders.

(c) As used in this Agreement, (i) the words “include” and “including,” and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words “without limitation” and (ii) the words “hereby,” “herein,” “hereunder” and “hereto” shall be deemed to refer to this Agreement in its entirety and not to any specific section of this Agreement.

(d) Except as otherwise indicated, all references in this Agreement to “Sections” and “Exhibits” are intended to refer to Sections of this Agreement and Exhibits to this Agreement.

(e) The headings and subheadings used in this Agreement are for convenience of reference only and shall have no force or effect whatsoever in interpreting any of the provisions of this Agreement.

7.8 Time is of the Essence; Enforcement. Time is of the essence of this Agreement. Each of the parties hereto agrees that irreparable damage would occur and that the parties would not have any adequate remedy at Applicable Law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, this being in addition to any other remedy to which they are entitled at Applicable Law or in equity.

7.9 Amendment; Waiver. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto. Any waiver of any of the terms or conditions of this Agreement must be in writing and must be duly executed by or on behalf of the party to be charged with such waiver. Except as expressly set forth in this Agreement, the failure of a party to exercise any of its rights hereunder or to insist upon strict adherence to any term or condition hereof on any one occasion shall not be construed as a waiver or deprive that party of the right thereafter to insist upon strict adherence to the terms and conditions of this Agreement at a later date. Further, no waiver of any of the terms and conditions of this Agreement shall be deemed to or shall constitute a waiver of any other term of condition hereof (whether or not similar).

7.10 Expenses. All costs and expenses, including, without limitation, fees and disbursements of counsel, financial advisors and accountants, incurred in connection with this Agreement shall be paid by the Party incurring such costs and expenses, whether or not the ATA Closing shall have occurred.

7.11 Entire Agreement. This Agreement, along with the other Transaction Documents and instruments delivered in connection herewith and to the extent referenced herein, the Merger Agreement, constitutes the entire agreement of the Parties with respect to the subject matter hereof and supersedes all prior agreements, representations, undertakings and understandings, both written and oral, between the Company and Newco with respect to the subject matter hereof.

-26-

7.12 Assignment. Subject to this Section 7.12, this Agreement shall not be assignable by either Party to any Third Party without the prior written consent of the other Party (which consent shall not be withheld unreasonably). Notwithstanding the foregoing, either Party may assign this Agreement, without the written consent of the other Party, (a) to an Affiliate, provided that the assigning Party guarantees the performance of this Agreement by such Affiliate, or (b) to a successor to some or all of such assigning Party’s assets relating to this Agreement (whether by asset purchase, merger or otherwise), provided that any such assignee agrees in writing to be bound by the terms of this Agreement. Any assignment of this Agreement in contravention of this Section 7.12 shall be null and void. Nothing herein shall be deemed to prevent Newco from assigning or transferring to one or more Third Parties any of the Transferred Assets subject to the terms and conditions of this Agreement, including Section 2.3.

7.13 Ownership of Attorney-Client Privilege. To the extent that communications, prior to the closing of the Merger (the “Merger Closing”), between Company and its representatives, on the one hand, and its counsel (“Counsel”), on the other hand, relate to the Transferred Assets, Transferred Liabilities or this Agreement, such communication shall be deemed to be attorney-client confidences that belong solely to Newco, and not the Company. Neither Company nor any of its Affiliates shall have access to (and Company hereby waives any right of access it may otherwise have with respect to) any such communications, or the files or work product of Counsel generated prior to the Merger Closing, to the extent that they relate to the Transferred Assets, Transferred Liabilities or this Agreement. Without limiting the generality of the foregoing, Company acknowledges and agrees, upon and after the Merger Closing: (i) Newco and Counsel shall be the sole holders of the attorney-client privilege with respect to the above-described communications and work product, and neither Company nor any of its Affiliates shall be a holder thereof; (ii) to the extent that files or work product of Counsel, prepared prior to the Merger Closing in respect of a Transferred Asset, Transferred Liability or this Agreement constitute property of the client, only Newco shall hold such property rights and have the right to waive or modify such property rights; and (iii) Counsel shall have no duty whatsoever to reveal or disclose any such attorney-client communications, files or work product (collectively, the “Privileged Items”) to Company or any of its Affiliates by reason of any attorney-client relationship between Counsel and the Company or otherwise; provided that, to the extent any Privileged Item is both related to a Privileged Item and other items owned by the Company, Counsel and Newco shall provide appropriately redacted versions of such communications, files or work product to the Company or its Affiliates. Notwithstanding and without limiting the foregoing, in the event that a dispute arises between or among any of Newco, Company or their Affiliates concerning the matters contemplated in this Agreement, Company, for itself and on behalf of its Affiliates, agrees that Company and its Affiliates shall not offer into evidence or otherwise attempt to use or assert the foregoing attorney-client communications, files or work product against Newco or its Affiliates.

7.14 Delays or Omissions. Except as expressly provided herein, no delay or omission to exercise any right, power or remedy accruing to any Party to this Agreement upon any breach or

-27-

default of the other Party under this Agreement shall impair any such right, power or remedy of such non-defaulting Party, nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring, nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any Party of any breach or default under this Agreement, or any waiver on the part of any Party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement or by law or otherwise afforded to any Party to this Agreement, shall be cumulative and not alternative.

7.15 No Third Party Beneficiaries. This Agreement shall be binding upon and inure solely to the benefit of the Parties and their permitted successors and assigns, and nothing herein, express or implied, is intended to or shall confer upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

LICENSE AGREEMENT

THIS LICENSE AGREEMENT (the “Agreement”), is made as of May     , 2014 (the “Effective Date”), by and between ImmuMetrix, Inc., a Delaware corporation (“Company”) having its principal offices at 0000 Xxxxxx Xxxxx, Xxxx Xxxx, XX 00000, and [NEWCO], a corporation organized under the laws of Delaware (“Newco”) having its principal offices at                     .

BACKGROUND

WHEREAS, Company has rights to certain Stanford Patents (as defined below).

WHEREAS, Newco desires to obtain a license under the Stanford Patents in the Territory in the Newco Field (as defined below), and Company desires to grant such license, all on the terms and conditions herein.

NOW, THEREFORE, Company and Newco agree as follows:

AGREEMENT

ARTICLE 1

DEFINITIONS

1.1 “Affiliates” means, with respect to any person, another person that, directly or indirectly, through one or more intermediaries, Controls, is Controlled by, or is under common Control with such person. “Control” means, as to any Person, beneficial ownership, direct or indirect, of at least fifty percent (50%) of the equity securities of the subject entity entitled to vote in the election of directors (or, in the case of an entity that is not a corporation, for the election of the corresponding managing authority), and the terms “Controlled by”, “under common Control with” and “Controlling” shall have correlative meanings.

1.2 “Defined Organ Transplant Field” means the use of cell-free DNA detection or immune repertoire profiling to diagnose and clinically manage solid organ and bone marrow human transplant recipients, excluding the detection, diagnosis or clinical management of cancer, or conditions that are a precursor to cancer. In all cases, the measurement of the level, cell-free DNA size distribution, or other test parameters to assess cell-free DNA and immune repertoire profiling shall be applied uniquely to transplant recipients or pre-transplant patients who are on a designated transplant waiting list, and shall include, but not be limited to, surveillance for acute rejection, chronic rejection, allograft vasculopathy, immunosuppression optimization, organ toxicity, overall immune status in relation to infectious disease signature and organ damage due to infection.

1.3 “HHMI” means the Xxxxxx Xxxxxx Medical Institute, and any successors-in-interest.

1.4 “Licensed Product” means a product or part of a product, the making, using, importing or selling of which, absent this license, infringes, induces infringement, or contributes to infringement of a Valid Claim of a Stanford Patent. For clarity, discovery or development of a product using Stanford Patents or technology or rights licensed hereunder does not cause such product to be a Licensed Product.

1.5 “Net Sales” means all gross revenue derived through Newco or sublicensees from sales of Licensed Product. Net Sales excludes the following items (but only as they pertain to the making, using, importing or selling of Licensed Products, are included in gross revenue, and are separately billed):

1.5.1 import, export, excise and sales taxes, and custom duties;

1.5.2 costs of insurance, packing, and transportation from the place of manufacture to the customer’s premises or point of installation;

1.5.3 costs of installation at the place of use; and credit for returns, allowances, or trades.

1.6 “Newco Field” means (i) the detection, diagnosis or clinical management of cancer, or conditions that are a precursor to cancer and all other applications and purposes outside the Defined Organ Transplant Field and (ii) products that are used outside the Defined Organ Transplant Field but also have utility within the Defined Organ Transplant Field (such as a diagnostic for infectious disease intended for a broader patient population but which is useful also for transplant recipients). For avoidance of doubt, the Newco Field does not include products for assessing whether a solid organ transplant or bone marrow transplant is or will be rejected.

1.7 “Stanford” means the Board of Trustees of the Xxxxxx Xxxxxxxx Junior University, and any successors-in-interest.

1.8 “Stanford License” means the Amended and Restated Exclusive Agreement between Company and Stanford relating to the Stanford Patents, dated as of January 27^th, 2014, a copy of which is attached hereto as Exhibit 1.

1.9 “Stanford Patent(s)” means any domestic or foreign patent application or patent that claims priority to, or common priority with, any application listed in Appendix C of the Stanford License. Any claim of an unexpired Stanford Patent is presumed to be valid unless it has been held to be invalid by a final judgment of a court of competent jurisdiction from which no appeal can be or is taken. “Stanford Patent” excludes any continuation-in-part (CIP) patent application or patent.

1.10 “Stanford Technology” means the information or materials listed in Appendix D of the Stanford License, that has been or will be provided by Stanford to Company. Technology may or may not be confidential in nature.

1.11 “Territory” means the entire world.

1.12 “Valid Claim” means a claim contained in an issued and unexpired patent or a pending patent application which has not been held unenforceable or invalid by a decision of a court or other governmental agency of competent jurisdiction, unappealable or unappealed within the time allowed for appeal, and which has not been admitted to be invalid or unenforceable through

-2-

abandonment, reissue, disclaimer or otherwise. Notwithstanding the foregoing, if a claim of a pending patent application within the Stanford Patents has not issued as a claim of an issued patent within the Stanford Patents, within five (5) years after the filing date from which such claim takes priority, such pending claim shall not be a Valid Claim for purposes of this Agreement.

ARTICLE 2

LICENSE

2.1 License. Subject to the terms and conditions set forth in this Agreement, Company hereby grants to Newco: (a) a sublicense under the Stanford Patents in the Newco Field to make, have made, use, import, offer to sell and sell Licensed Products in the Territory and (b) a sublicense under Company’s nonexclusive interest in the Stanford Technology in the Newco Field to research, develop, make, have made, use, import, offer to sell and sell Licensed Product and otherwise exploit Stanford Technology in the Territory. The sublicenses granted here are exclusive for (i) the detection, diagnosis or clinical management of cancer, or conditions that are a precursor to cancer, and (ii) all applications and purposes outside the Defined Organ Transplant Field, and are non-exclusive as to clause (ii) of the Newco Field. For clarity, Newco acknowledges that Company’s license to the Stanford Technology is non-exclusive and that accordingly, that (A) the exclusivity granted to Newco under subsection (b) above is limited to the non-exclusive interest in the Technology conveyed to Company under the Stanford License, and (B) that Stanford retained the right to grant additional licenses under the Stanford Technology to third parties. The non-exclusive rights retained by Company with respect to applications and purposes covered under clause (ii) of the Newco Field shall be subject to the limitations set in Section 2.3(b) of the Asset Transfer Agreement between the parties entered into together with this Agreement, except that “Licensed Product” shall mean as defined in this Agreement.

2.2 Sublicenses. Newco shall have the right to grant and authorize further sublicenses under Stanford Patents and Stanford Technology, subject to its compliance with its obligations to Stanford set forth in Exhibit 2, subsection (b).

2.3 Certain Additional Terms for the Benefit of Stanford. Newco agrees to be bound for the benefit of Stanford and HHMI (as applicable) by the provisions set forth in Exhibit 2. It is acknowledged and agreed that the provisions set forth in Exhibit 2 are for the exclusive benefit of Stanford and, as applicable, HHMI. It is further agreed that Stanford and HHMI as the sole intended beneficiaries of such provisions, shall have the sole and exclusive right to enforce such provisions.

2.4 No Implied Licenses. Nothing herein shall be construed as granting Newco, by implication, estoppel or otherwise, any license or other right to any intellectual property of Company other than the Stanford Patents or to grant to Newco any right or license other than those expressly granted herein.

-3-

2.5 Maintenance of the Stanford License. Company shall comply with all of its obligations under the Stanford License and will not terminate the Stanford License or amend the Stanford License in any manner which diminishes the rights of Newco or increases any obligations of Newco with respect to the Licensed Rights (“Detriment”) without the consent of Newco. In the event that Company amends the Stanford License to obtain more favorable terms from Stanford (e.g., negotiates a lower royalty rate or a higher third party royalty offset) Company will extend such benefits to Newco and this Agreement shall be amended to reflect such more favorable terms. In addition, Company will notify Newco promptly, if Company and/or any of its Affiliates receives notice, whether or not there is a cure period, from Stanford that Company and/or any of its Affiliates is in material breach of the Stanford License, and/or notice from Stanford which purports to terminate the Stanford License or modify the Stanford License in a manner that would cause a Detriment. Company will and will cause its Affiliates to take prompt and commercially reasonable steps to cure any such breach. Company acknowledges that any breach of the Stanford License by Company and/or its Affiliates may result in irreparable damage to Newco and will entitle Newco to seek, in addition to any other right or remedy it may be entitled to, specific performance or other equitable remedies without the posting of any bond or other security.

2.6 Immune Repertoire Rights. The Parties acknowledge that, prior to the Effective Date, Newco has engaged in discussions with Stanford regarding:

(a) a license to certain immune repertoire patents formerly subject to that certain option agreement entered into by Company and Stanford, effective December 15, 2010 and now lapsed (the “Additional IR Patents,” and “Option Agreement,” respectively); and

(b) a license to newly filed patent application filed with respect to the inventions disclosed in Stanford invention disclosure S09-367B (the “Stanford Patent Application”).

In the event Newco is successful in obtaining a license to the Additional IR Patents and/or the Stanford Patent Application, Newco shall, to the extent the field of use of such license includes the Defined Organ Transplant Field, grant to Company a sublicense under such patents for purposes of developing, manufacturing and commercializing Licensed Products in the Defined Organ Transplant Field. Such sublicense would be exclusive subject to Newco’s limited rights in the Defined Organ Transplant Field under clause (ii) of the Newco Field, as to which the sublicence would be non-exclusive. All other terms of such sublicense shall be substantially identical to the terms of this Agreement, which shall apply reciprocally, mutatis mutandis. In the event Newco does not obtain such a license within 7.5 months, Company may seek a direct license to such patent rights from Stanford for the Defined Organ Transplant Field, and agrees not to seek such a license prior to such time. Company covenants that in the event that it exercises its right to seek a direct license to such patent rights from Stanford as permitted under this Section 2.6, unless otherwise agreed by Newco in writing, Company (i) will limit the field of its license from Stanford to the Defined Organ Transplant Field, (ii) will limit its license to the matters covered under clause (ii) of the Newco Field a non-exclusive license or co-exclusive with Newco.

ARTICLE 3

PAYMENTS

3.1 Milestones: To the extent Newco’s exercise of the sublicenses granted to it under Section 2.1 above triggers a payment obligation under Section 7.3 (Milestone Payments) of the Stanford Agreement, Newco agrees to pay such milestone payment to Stanford.

3.2 Royalties. Newco will pay to Company earned royalties (Y%) on Net Sales as follows (which amount is intended to be limited to a pass-through of the royalty obligations owing to Stanford):

3.2.1 Newco or its sublicensee will pay Company a 3% royalty on Net Sales of each Licensed Product sold.

3.2.2 Earned royalties paid to third parties will offset earned royalties payable to Company under Section 3.2.1 above at a rate 0.25% for each 1% that Newco pays to third parties provided that the third party technology for which Newco pays earned royalties is reasonably useful and the earned royalty rate Newco pays them is commercially reasonable for the type of technology and such license is reasonably useful to make, use and sell the Licensed Product, licensed hereunder. In no event shall the royalty payable to Company under Section 3.2.1 above be reduced by more than 50%.

3.2.3 In the event that a Licensed Product is sold in combination with one or more other products or components for which no royalty would be due hereunder if sold separately (“Other Product(s)”), Net Sales from such sales shall be calculated by multiplying the net selling price of the combination product by the fraction A/(A + B), where A is the average gross selling price during the applicable calendar quarter of the Licensed Product sold separately and B is the average gross selling price during the applicable calendar quarter of the Other Product(s). In the event that separate sales of the Licensed Product and/or of the Other Product(s) were not made during the applicable calendar quarter, then the Net Sales on the combination product shall be as reasonably as mutually agreed upon by Company and Newco in good faith, between such Licensed Product and such Other Product(s), based upon their relative importance and proprietary protection. In the event that Company (or Stanford) reasonably believes that the average gross selling price during the applicable calendar quarter of the Licensed Product sold separately and the Other Product(s) sold separately do not accurately reflect the relative importance and proprietary protection of the Licensed Product and such Other Product(s) for the purposes of determining Net Sales of a combination product, Company may provide Newco notice thereof and the parties thereafter shall reasonably discuss and agree in good faith upon an alternative allocation with respect thereto.

3.2.4 For clarity, Newco’s right to offset earned royalties for third party technology as set forth above shall not apply with respect to third party technology reasonably useful to make, use and sell a Licensed Product that is a combination product for which Net Sales is calculated as set forth in the preceding paragraph to the extent such third party technology is only useful for the making, using or selling the Other Product(s) in such combination product separately

3.3 Obligation to Pay Royalties. A royalty is due Company under this Agreement for any activity conducted under the licenses granted. For convenience’s sake, the amount of that royalty is calculated using Net Sales. Nonetheless, if certain Licensed Products are made, used, imported, or offered for sale before the date this Agreement terminates, and those Licensed Products are sold after the termination date, Newco will pay Company an earned royalty for its exercise of rights based on the Net Sales of those Licensed Products.

-5-

3.4 Currency Conversion. Newco will calculate the royalty on sales in currencies other than U.S. Dollars using the appropriate foreign exchange rate for the currency quoted by the Wall Street Journal on the close of business on the last banking day of each calendar quarter. Newco will make royalty payments to Company in U.S. Dollars.

3.5 Non-U. S. Taxes. Newco will pay all non-U.S. taxes related to royalty payments. These payments are not deductible from any payments due to Company.

3.6 Interest. Any payments not made when due will bear interest at the lower of (a) the Prime Rate published in the Wall Street Journal plus 200 basis points or (b) the maximum rate permitted by law.

ARTICLE 4

ROYALTY REPORTS; PAYMENTS; ACCOUNTING

4.1 Royalty Payment and Report. Beginning with the first sale of a Licensed Product by Newco or a sublicensee, Newco will submit to Company a written report (even if there are no sales) and an earned royalty payment within 30 days after the end of each calendar quarter. This report will be in the form of Appendix B of the Stanford License and will state the number, description, and aggregate Net Sales of Licensed Product during the completed calendar quarter. The report will include an overview of the process and documents relied upon to permit Company to understand how the earned royalties are calculated. With each report Newco will include any earned royalty payment due Company for the completed calendar quarter (as calculated under Section 3.2).

4.2 Termination Report. Newco will pay to Company all applicable royalties and submit to Company a written report within 90 days after the license terminates. Newco will continue to submit earned royalty payments and reports to Company after the license terminates, until all Licensed Products made or imported under the license have been sold.

4.3 Accounting. Newco agrees to keep and maintain records for a period of three (3) years showing the manufacture; sale, use, and other disposition of products or processes sold or otherwise disposed of under the license herein granted. Such records will include general ledger records showing cash receipts and expenses, and records which include production records, customers, serial numbers and related information in sufficient detail to enable the royalties payable hereunder by Newco to be determined. Newco further agrees to permit its books and records to be examined by Company and/or its designee from time to time to the extent necessary to verify reports provided for in Section 4.1. Such examination is to be made by Company or its designees, at the expense of Company, except in the event that the results of the audit reveal an underreporting of royalties due Company of five percent (5%) or more in any calendar year, then the audit costs shall be paid by Newco.

4.4 Progress Report. Upon the request of Company, on or before August 1 of each year, Newco shall make a written annual report to Company covering the preceding year ending June 30, regarding the activities of Newco in commercializing the Stanford Patents.

ARTICLE 5

PAYENT PROSECUTION AND ENFORCEMENT

5.1 Patent Prosecution and Maintenance. Stanford will be responsible for preparing, filing, and prosecuting broad patent claims (including any interference or reexamination actions) for Stanford’s benefit in the Territory and for maintaining all Stanford Patents. Company shall: (a) keep Newco reasonably informed with respect to Stanford’s prosecution and maintenance of all Stanford Patents with relevance to the Newco Field, and shall at a minimum provide Newco with semi-annual written reports with respect to the same; (b) furnish to Newco copies of all communications received from Stanford and Stanford’s patent counsel with respect to the preparation, filing and prosecution of patent applications with claims relevant to the Newco Field including copies of all material documents filed with or received from any patent office after the Effective Date relating to the same that are provided to Company by Stanford or Stanford’s patent counsel; (c) allow Newco a reasonable opportunity to comment on substantive actions being considered by Stanford and/or Company in connection with prosecuting claims of Stanford Patents with relevance to the Newco Field and (d) reasonably considering and relaying to Stanford any comments provided by Newco with respect to the actions described in (c) above.

5.2 Patent Enforcement.

5.2.1 If either party, directly or through an Affiliate or sublicensee (or in the case of Company, through Stanford), learns of any actual or possible, direct or indirect, infringement of the Stanford Patents by another person or entity by the manufacture, sale, import, use or other exploitation of a product or service in the Newco Field (a “Competing Product Infringement”), it shall promptly provide written notice to the other party of such Competing Product Infringement and shall promptly supply such other party with all evidence it possesses pertaining to such Competing Product Infringement.

5.2.2 As between Newco and Company, Newco (directly or through its designee) shall have the sole right, but not the obligation, to seek to xxxxx any Competing Product Infringement or to file suit against an infringing person or entity with respect to such Competing Product Infringement (each, an “Competing Product Infringement Action”). In the event Newco exercises it right to initiate a Competing Product Infringement Action, it will so notify Company and Company will in turn notify Stanford in writing of its appointment of Newco (or Newco’s specified designee) as Company’s designee in connection with such action. Newco shall keep Company reasonably informed of the progress of any such Competing Product Infringement Action. Company shall cooperate fully with Newco, including, either as required by law or at the request of Newco, by joining as a nominal party, cooperating with Stanford to enable Newco (and its designee(s)) to exercise such rights) and executing such documents as may reasonably be required for such Competing Product Infringement Action, all at the expense of Newco. In the event that Newco desires or is required to join Stanford as a party in a Competing Product Infringement Action, such joinder will be in accordance with the terms and conditions described in Section 14.4 of the Stanford License.

-7-

5.2.3 If Newco does not initiate a Competing Product Infringement Action within 120 days of a request by Stanford to do so (which request may be made directly to Newco or relayed through Company), it is understood that Stanford may institute and prosecute a Competing Product Infringement Action so long as it conforms with the requirements of Section 14.6 of the Stanford License.

5.2.4 Any recovery (whether by settlement or otherwise) obtained as a result of a Competing Product Infringement Action shall be shared as follows:

(a) Company, if joined or cooperating in such action, shall first be entitled to recover its out-of-pocket costs and expenses (including reasonable attorneys’ fees) incurred in connection with such action; and

(b) any remainder of recovery shall be retained by the Newco.

5.2.5 The non-controlling party shall, at the reasonable request and expense of the party controlling any enforcement or declaratory action under this Section 5.2, fully cooperate with the controlling party, including making available relevant records, papers, information, samples, specimens, and the like. The party controlling the enforcement shall keep the non-controlling party reasonably informed of the progress of such action, and the non-controlling party shall have the right to participate in such enforcement or declaratory action with counsel of its own choice at its own expense.

5.3 Subordination to Stanford License. The obligations of Company and the rights of Newco under Sections 5.2 and 5.3 shall be subject to and limited by terms of Article 14 of the Stanford License. To the extent Company has the right to do so under the terms of Article 14 of the Stanford License, Company shall cooperate with Newco to prosecute and enforce such Stanford Patents in the same manner as set forth in Sections 5.2 and 5.3 above. Withouth limiting the foregoing, Company agrees to take such steps as are reasonably requested by Newco to extend to Newco the rights and benefits provided to Company under Article 14 of the Stanford License, including by taking reasonable measures to ensure that Stanford will diligently pursue any action initiated by Stanford and keeping Newco reasonably apprised of all developments in the suit, seeking Newco’s input and approval on any substantive submissions or positions taken in the litigation regarding the scope, validity and enforceability of a Stanford Patent, ensuring that Stanford does not prosecute, settle or otherwise compromise any such suit in a manner that adversely affects Newco’s interests without Newco’s prior written consent, and otherwise enabling Newco to exercise Company’s rights under Article of the Stanford License for the benefit of Newco hereunder.

AMENDED AND RESTATED EXCLUSIVE AGREEMENT

This Amended and Restated Agreement (“Restated Agreement”) between THE BOARD OF TRUSTEES OF THE XXXXXX XXXXXXXX JUNIOR UNIVERSITY (“Stanford”), an institution of higher education having powers under the laws of the State of California, and ImmuMetrix, Inc. (“ImmuMetrix”), a corporation having a principal place of business at 0000 Xxxxxx Xxxxx, Xxxx Xxxx, XX, is effective on the 27^th day of January, 2014, (“Restatement Effective Date”).

1 BACKGROUND

Stanford has an assignment of an invention for a rapid, inexpensive, non-invasive method to monitor organ transplant recipients for life-threatening graft rejection. It is entitled “Non-invasive diagnosis of graft rejection in organ transplant patients,” was invented in the laboratory of Dr. Xxxxxxx Xxxxx, a Xxxxxx Xxxxxx Medical Institute (“HHMI”) investigator at Stanford, and is described in Stanford Docket S09-367. The invention was made in the course of research supported by the National Institutes of Health and HHMI. Stanford wants to have the invention perfected and marketed as soon as possible so that resulting products may be available for public use and benefit.

Effective as of August 19, 2011 (“Original Sequencing Effective Date”), Stanford and ImmuMetrix, LLC entered into the Exclusive License Agreement (“Sequencing Agreement”) pursuant to which ImmuMetrix, LLC obtained from Stanford a world-wide exclusive license under the Licensed Patents for use in research and diagnostic fields using sequencing, as more completely set forth in the Sequencing Agreement. Additionally, effective as of February 10, 2012 (“Original PCR Effective Date”), Stanford and ImmuMetrix, LLC entered into the Exclusive License Agreement (“PCR Agreement”) pursuant to which ImmuMetrix, LLC obtained from Stanford a world-wide exclusive license under the Licensed Patents for use in research and diagnostic fields using PCR assays, as more completely set forth in the PCR Agreement.

As described, and consented to by Stanford, in that certain letter from ImmuMetrix, LLC to Stanford dated March 26, 2013, ImmuMetrix, LLC assigned to ImmuMetrix, Inc. all rights and obligations under the Sequencing Agreement and the PCR Agreement.

Now, the parties desire to amend the terms of the Sequencing Agreement and the PCR Agreement and restate the Sequencing Agreement and PCR Agreement in their entirety on the terms and conditions as set forth in this Restated Agreement.

2 DEFINITIONS

2.1 “Agreement” means collectively, (i) the Sequencing Agreement as in effect from the Original Sequencing Agreement Effective Date until the Restatement Effective Date, (ii) the PCR Agreement as in effect from the Original PCR Effective Date until the Restatement Effective Date and (iii) this Restated Agreement, which pursuant to Section 20.6 below, replaces the Sequencing Agreement and the PCR Agreement in their entirety as of the Restatement Effective Date.

S09-367 : GWK

under the Licensed Patents in the Licensed Field of Use such as up front fees, annual fees, and milestone fees, without limitation, but excluding any consideration for an earned royalty that is calculated based on sales of Licensed Product, investments in ImmuMetrix stock or debt, payment or reimbursement of R&D expenses calculated on a fully burdened basis, supply of Licensed Products or other products or materials to such sublicensee, reimbursement for patent prosecution costs and patent maintenance expenses, licensing of patents or other intellectual property other than Licensed Patents, and the sale of all or substantially all of the business or assets of ImmuMetrix (or its assignee) whether by merger, sale of stock or assets or otherwise.

2.10 “Stanford Indemnitees” means Stanford and Stanford Hospitals and Clinics, and their respective trustees, officers, employees, students, and agents.

2.11 “Sublicense” means any agreement between ImmuMetrix and a third party that contains a grant to Stanford’s Licensed Patents regardless of the name given to the agreement by the parties; however, an agreement to make, have made, use or sell Licensed Products on behalf of ImmuMetrix is not considered a Sublicense.

2.12 “Technology” means the Licensed Patents and that additional information or materials listed in Appendix D that will be provided by Stanford to ImmuMetrix. Technology may or may not be confidential in nature.

2.13 “Valid Claim” means a claim contained in an issued and unexpired patent or a pending patent application which has not been held unenforceable or invalid by a decision of a court or other governmental agency of competent jurisdiction, unappealable or unappealed within the time allowed for appeal, and which has not been admitted to be invalid or unenforceable through abandonment, reissue, disclaimer or otherwise. Notwithstanding the foregoing, if a claim of a pending patent application within the Licensed Patents has not issued as a claim of an issued patent within the Licensed Patents, within five (5) years after the filing date from which such claim takes priority, such pending claim shall not be a Valid Claim for purposes of this Agreement.

3 GRANT

3.1 Grant. Subject to the terms and conditions of this Agreement, Stanford grants ImmuMetrix (a) an exclusive license under the Licensed Patent in the Licensed Field of Use to make, have made, use, import, offer to sell and sell Licensed Product in the Licensed Territory and (b) a non-exclusive license under the Technology in the Licensed Field of Use to research, develop, make, have made, use, import, offer to sell and sell Licensed Product and otherwise exploit Technology in the Licensed Territory.

Page 3 of 32

S09-367 : GWK

3.3 Retained Rights. Stanford retains the right, on behalf of itself and all other non-profit academic research institutions, to practice the Licensed Patent and use Technology for any non-profit purpose, including sponsored research and collaborations. ImmuMetrix agrees that, notwithstanding any other provision of this Agreement, it has no right to enforce the Licensed Patent against any such institution. Stanford and any such other institution have the right to publish any information included in the Technology or a Licensed Patent. ImmuMetrix acknowledges that HHMI has retained an irrevocable, perpetual, worldwide, royalty-free, nonexclusive, nontransferable license to the Licensed Patents and Technology.

3.4 Specific Exclusion. Stanford does not:

(A) grant to ImmuMetrix any other licenses, implied or otherwise, to any patents or other rights of Stanford other than those rights granted under Licensed Patent, regardless of whether the patents or other rights are dominant or subordinate to any Licensed Patent, or are required to exploit any Licensed Patent or Technology;

(B) commit to ImmuMetrix to bring suit against third parties for infringement, except as described in Article 14; and

(C) agree to furnish to ImmuMetrix any technology or technological information other than the Technology or to provide ImmuMetrix with any assistance.

4 SUBLICENSING

4.1 Permitted Sublicensing. ImmuMetrix may grant and authorize sublicenses in the Licensed Field of Use only if at the time of such grant ImmuMetrix or its sublicensee is developing or selling Licensed Products. Sublicenses with any exclusivity must include diligence requirements commensurate with the diligence requirements of Appendix X. Xxxxxxxx agrees that ImmuMetrix may apportion a commercially reasonable percentage of sublicensing payments made to Stanford pursuant to Section 4.6, provided however that ImmuMetrix provides Stanford with the proposed apportionment and justification prior ImmuMetrix’s payment pursuant to Section 8.1. Stanford and ImmuMetrix agree to meet to discuss such proposed apportionment if in Stanford’s opinion the apportionment does not reasonably reflect the value of the Licensed Patents.

4.2 Required Sublicensing. If ImmuMetrix is unable or unwilling to serve or develop a potential market or market territory for which there is a company willing to be a sublicensee, ImmuMetrix will, at Stanford’s request, negotiate in good faith a Sublicense with any such sublicensee. Stanford would like licensees to address unmet needs, such as those of neglected patient populations or geographic areas, giving particular attention to improved therapeutics, diagnostics and agricultural technologies for the developing world.

4.3 Sublicense Requirements. Any Sublicense granted under this Agreement:

(A) is subject to this Agreement;

(B) will prohibit sublicensee from paying royalties to an escrow or other similar account;

Page 4 of 32

S09-367 : GWK

(C) will expressly include the provisions of Articles 8, 9, 10, 12, and Section 19.4 for the benefit of Stanford and/or HHMI, as the case may be; and

(D) will require the transfer of all the sublicensee’s applicable obligations to ImmuMetrix with respect to the sublicense, including the payment of royalties specified in the Sublicense (up to the earned royalty rates set forth in Article 7)), to Stanford or its designee, if this Agreement is terminated. If the sublicensee is a spin-out from ImmuMetrix, ImmuMetrix must guarantee the sublicensee’s performance with respect to the payment of Stanford’s share of Sublicense royalties.

4.4 Copy of Sublicenses and Sublicensee Royalty Reports. ImmuMetrix will submit to Stanford a copy of each Sublicense, any subsequent amendments and all copies of sublicensees’ royalty reports. Beginning with the first Sublicense, the Chief Financial Officer or equivalent will certify annually regarding the name and number of sublicensees.

4.5 Litigation by Sublicensee. Any Sublicense must include the following clauses:

(A) In the event sublicensee brings an action seeking to invalidate any Licensed Patent:

(1) sublicensee will double the payment paid to the ImmuMetrix during the pendency of such action. Moreover, should the outcome of such action determine that any claim of a patent challenged by the sublicensee is both valid and infringed by a Licensed Product, sublicensee will pay triple times the payment paid under the original Sublicense;

(2) sublicensee will have no right to recoup any royalties paid before or during the period challenge;

(3) any dispute regarding the validity of any Licensed Patent shall be litigated in the courts located in Santa Xxxxx County, and the parties agree not to challenge personal jurisdiction in that forum;

(4) sublicensee shall not pay royalties into any escrow or other similar account.

(B) Sublicensee will provide written notice to Stanford at least three months prior to bringing an action seeking to invalidate a Licensed Patent. Sublicensee will include with such written notice an identification of all prior art it believes invalidates any claim of the Licensed Patent.

Notwithstanding the foregoing, in the event a sublicensee files a counterclaim asserting invalidity of one or more Licensed Patents in response to an actual suit by Stanford, such sublicensee shall not be deemed to have brought an action to invalidate a Licensed Patent and this Section 4.5 shall not apply.

S09-367 : GWK

4.6 Sharing of Sublicensing Income. ImmuMetrix will pay Stanford the following percent of all Nonroyalty Sublicensing Consideration, excluding earned royalties (ImmuMetrix shall guarantee earned royalties for sales by sublicensees as if the sales were made by ImmuMetrix):

(A) [***]% of Nonroyalty Sublicensing Consideration before and [***]% of Nonroyalty Consideration after demonstration, that cell free DNA of a transplanted organ, other than a human heart, may be detected in the blood or other bodily fluids or tissues of the host, and that the cell free DNA concentration increases during a transplant rejection event as identified by other established clinical means, but before occurrence of an event listed in clause (B) below;

(B) [***]% of Nonroyalty Sublicensing Consideration after the earlier of (i) commercial launch as indicated by a first sale or (ii) expenditure after the Restatement Effective date of $[***] for the research, development, regulatory approval and/or commercialization, in either case of a Licensed Product by ImmuMetrix directly or through its Affiliates, sublicensees and/or other contractors, but before occurrence of the event listed in clause (C) below; or

(C) [***]% of Nonroyalty Sublicensing Consideration after annual sales of Licensed Product by ImmuMetrix, its Affiliates and/or its sublicensees reach $[***].

4.7 Royalty-Free Sublicenses. If ImmuMetrix pays all royalties due Stanford from a sublicensee’s Net Sales, ImmuMetrix may grant that sublicensee a royalty-free or non-cash:

(A) Sublicense or

(B) cross-license.

5 GOVERNMENT RIGHTS

This Agreement is subject to Title 35 Sections 200-204 of the United States Code. Among other things, these provisions provide the United States Government with nonexclusive rights in the Licensed Patent. They also impose the obligation that Licensed Product sold or produced in the United States be “manufactured substantially in the United States.” ImmuMetrix will ensure all obligations of these provisions are met.

6 DILIGENCE

6.1 Milestones. Because the invention is not yet commercially viable as of the Original Sequencing Effective Date, ImmuMetrix, directly or through its Affiliates, sublicensees and/or other contractors, will diligently develop, manufacture, and sell and/or otherwise commercialize Licensed Product and will diligently develop markets for Licensed Product. In addition, ImmuMetrix, directly or through its Affiliates, sublicensees and/or other contractors, will meet the milestones shown in Appendix A, and notify Stanford in writing as each milestone is met. Notwithstanding the foregoing and 15.2(A)(3), Stanford shall not unreasonably withhold its consent to any revision of the milestones described in Appendix A when requested in writing by ImmuMetrix to the extent such request is supported by evidence of technical difficulties or delays, including in clinical studies or regulatory

Page 6 of 32

***Confidential material redacted and filed separately with the Securities and Exchange Commission.

S09-367 : GWK

processes, outside of ImmuMetrix’s reasonable control. Additionally, ImmuMetrix shall be entitled to extend the due date of any one and any subsequent milestones described on Appendix A by [***] year upon payment to Stanford of [***] Dollars ($[***]) (a “[***]-Year Extension”), but only once for each milestone. ImmuMetrix shall have the right to extend such due dates from time to time for additional [***]-Year Extensions in accordance with the foregoing, but only after discussion and agreement by Stanford, such agreement not to be unreasonably withheld. Any such extension of a milestone due date shall also extend the due date for all subsequent related milestones by [***] year.

6.2 Progress Report. By March 1 of each year, ImmuMetrix will submit a written annual report to Stanford covering the preceding calendar year. The report will include information sufficient to enable Stanford to satisfy reporting requirements of the U.S. Government and for Stanford to ascertain progress by ImmuMetrix toward meeting this Agreement’s diligence requirements. Each report will describe, where relevant: ImmuMetrix’s progress toward commercialization of Licensed Product, including work completed, key scientific discoveries, summary of work-in-progress, current schedule of anticipated events or milestones, market plans for introduction of Licensed Product, and significant corporate transactions involving Licensed Product.

6.3 Clinical Trial Notice. ImmuMetrix will notify Stanford prior to commencing any clinical trials at Stanford.

6.4 Completed Milestones. Stanford acknowledges and agrees that ImmuMetrix has met the milestones numbered 1 through 6 set forth in Appendix A.

7 ROYALTIES

7.1 Issue Royalty. Stanford and ImmuMetrix acknowledge and agree that in consideration of the grant of the license hereunder, ImmuMetrix has paid to Stanford a noncreditable, nonrefundable license issue royalty of $20,000 upon signing the PCR Agreement and a noncreditable, nonrefundable license issue royalty of $20,000 upon signing the Sequencing Agreement and no addition issue royalty, except as set forth in Section 7.16 hereof, shall be due upon the signing of this Restated Agreement.

7.2 License Maintenance Fee. ImmuMetrix will pay Stanford a yearly license maintenance fee as follows:

(A) $[***] upon the first anniversary of the Restated Agreement;

(B) $[***] upon the second anniversary of the Restated Agreement; and

(C) $[***] upon the third and each subsequent anniversary of the Restated Agreement during the term of this Restated Agreement.

Yearly maintenance payments are nonrefundable, but they are creditable each year as described in Section 7.6.

Page 7 of 32

***Confidential material redacted and filed separately with the Securities and Exchange Commission.

S09-367 : GWK

7.3 Milestone Payments. ImmuMetrix will pay Stanford the following milestone payments with respects of the first Licensed Product:

(a)		Initiation of any clinical trial			$[***]
(b)		First commercial sale			$[***]
(c)		FDA or ex-US equiv. approval			$[***]
(d)		Sales > $[***]			$[***]
(e)		Patent Issuance			$[***]
(f)		Net Sales of Licensed Product exceeds $[***]			$[***]

7.4 Earned Royalty. ImmuMetrix will pay Stanford earned royalties (Y%) on Net Sales as follows:

ImmuMetrix or its sublicensee will pay Stanford a [***]% royalty on Net Sales of each Licensed Product sold.

Earned royalties paid to third parties will offset Stanford earned royalties at a rate [***]% for each [***]% that ImmuMetrix pays to third parties provided that the third party technology for which ImmuMetrix pays earned royalties is reasonably useful and the earned royalty rate ImmuMetrix pays them is commercially reasonable for the type of technology and such license is reasonably useful to make, use and sell the Licensed Product, licensed hereunder. In no event shall the royalty be reduced by more than [***]%.

In the event that a Licensed Product is sold in combination with one or more other products or components for which no royalty would be due hereunder if sold separately (“Other Product(s)”), Net Sales from such sales shall be calculated by multiplying the net selling price of the combination product by the fraction A/(A + B), where A is the average gross selling price during the applicable calendar quarter of the Licensed Product sold separately and B is the average gross selling price during the applicable calendar quarter of the Other Product(s). In the event that separate sales of the Licensed Product and/or of the Other Product(s) were not made during the applicable calendar quarter, then the Net Sales on the combination product shall be as reasonably as mutually agreed upon by Stanford and ImmuMetrix in good faith, between such Licensed Product and such Other Product(s), based upon their relative importance and proprietary protection. In the event that Stanford reasonably believes that the average gross selling price during the applicable calendar quarter of the Licensed Product sold separately and the Other Product(s) sold separately do not accurately reflect the relative importance and proprietary protection of the Licensed Product and such Other Product(s) for the purposes of determining Net Sales of a combination product, Stanford may provide ImmuMetrix notice thereof and the parties thereafter shall reasonably discuss and agree in good faith upon an alternative allocation with respect thereto. If the parties cannot so agree, the matter will be resolved by arbitration in accordance with Article 17.

Page 8 of 32

***Confidential material redacted and filed separately with the Securities and Exchange Commission.

S09-367 : GWK

For clarity, ImmuMetrix’s right to offset earned royalties for third party technology as set forth above shall not apply with respect to third party technology reasonably useful to make, use and sell a Licensed Product that is a combination product for which Net Sales is calculated as set forth in the preceding paragraph to the extent such third party technology is only useful for the making, using or selling the Other Product(s) in such combination product separately.

7.5 Earned Royalty if ImmuMetrix or Sublicensee Challenges the Patent. Notwithstanding the above, should ImmuMetrix bring an action seeking to invalidate any Licensed Patent, ImmuMetrix will pay royalties to Stanford at the rate of [***] x Y percent ([***] xY%) of the Net Sales of all Licensed Products sold during the pendency of such action. Moreover, should the outcome of such action determine that any claim of a patent challenged by ImmuMetrix is both valid and infringed by a Licensed Product, ImmuMetrix will pay royalties at the rate of [***] x Y percent ([***] xY%) of the Net Sales of all Licensed Products sold. Notwithstanding the foregoing, in the event ImmuMetrix files a counterclaim asserting invalidity of one or more Licensed Patents in response to an actual suit by Stanford, ImmuMetrix shall not be deemed to have brought an action to invalidate a Licensed Patent and this Section 7.5 shall not apply.

7.6 Creditable Payments. The license maintenance fee for a year may be offset against earned royalty payments due on Net Sales occurring in that year.

For example:

(A) if ImmuMetrix pays Stanford a $[***] maintenance payment for year Y, and according to Section 7.4 $[***] in earned royalties are due Stanford for Net Sales in year Y, ImmuMetrix will only need to pay Stanford an additional $[***] for that year’s earned royalties.

(B) if ImmuMetrix pays Stanford a $[***] maintenance payment for year Y, and according to Section 7.4 $[***] in earned royalties are due Stanford for Net Sales in year Y, ImmuMetrix will not need to pay Stanford any earned royalty payment for that year. ImmuMetrix will not be able to offset the remaining $[***] against a future year’s earned royalties.

7.7 Obligation to Pay Royalties. A royalty is due Stanford under this Agreement for any activity conducted under the licenses granted. For convenience’s sake, the amount of that royalty is calculated using Net Sales. Nonetheless, if certain Licensed Products are made, used, imported, or offered for sale before the date this Agreement terminates, and those Licensed Products are sold after the termination date, ImmuMetrix will pay Stanford an earned royalty for its exercise of rights based on the Net Sales of those Licensed Products.

7.8 No Escrow. ImmuMetrix shall not pay royalties into any escrow or other similar account.

7.9 Currency. ImmuMetrix will calculate the royalty on sales in currencies other than U.S. Dollars using the appropriate foreign exchange rate for the currency quoted by the Wall Street Journal on the close of business on the last banking day of each calendar quarter. ImmuMetrix will make royalty payments to Stanford in U.S. Dollars.

Page 9 of 32

***Confidential material redacted and filed separately with the Securities and Exchange Commission.

S09-367 : GWK

7.10 Non-U. S. Taxes. ImmuMetrix will pay all non-U.S. taxes related to royalty payments. These payments are not deductible from any payments due to Stanford.

7.11 Interest. Any payments not made when due will bear interest at the lower of (a) the Prime Rate published in the Wall Street Journal plus 200 basis points or (b) the maximum rate permitted by law.

7.12 [***]% Purchase Right. In any private offering of ImmuMetrix’s equity securities for cash (or in satisfaction of debt issued for cash), Stanford may purchase for cash up to [***]% of the securities issued in such offering. This right will expire following the first round of bona fide equity investment in ImmuMetrix from a single or group of investors which includes at least one venture capital, professional angel, corporate or other similar institutional investor and which either (i) is at least $[***] in size or (ii) involves the sale to outside investors of at least [***]% of the shares outstanding after such round on a Fully-Diluted Basis, but will apply to all shares to be issued in such round.

7.13 Future Offerings. In any private offering of ImmuMetrix’s equity securities in exchange for cash (or in satisfaction of debt issued for cash), Stanford may purchase for cash that number of the securities issued in such offering as is necessary for Stanford to maintain its pro rata ownership interest in ImmuMetrix on a Fully-Diluted Basis. This right is in addition to Stanford’s rights under Section 7.12. If both Section 7.12 and this Section 7.13 apply to an offering, the provision granting Stanford the greater purchase rights will govern.

7.14 Purchase Terms and Procedure, Exceptions; Public Offering. In any offering subject to Section 7.12 or 7.13, (i) Stanford’s purchase right shall be on the same terms as the other investors in the financing in question, except that Stanford shall not have any board representation or board meeting attendance rights, (ii) ImmuMetrix will give Stanford notice of the terms of the offering, including the names of the investors and the amounts to be invested by each, and Stanford may elect to exercise its right of purchase, in whole or in part, by notice given to ImmuMetrix within 20 days after receipt of ImmuMetrix’s notice and (iii) if Stanford elects not to purchase, or fails to give an election notice within such period, Stanford’s purchase right will not apply to the offering if (and only if and to the extent) it is consummated within 90 days on the same or less favorable (to the investor) terms as stated in ImmuMetrix’s notice to Stanford. Stanford’s rights under Sections 7.12 and 7.13 will not apply to the issuance of stock: (i) to employees and other service providers pursuant to a plan approved by ImmuMetrix’s Board of Directors; (ii) as additional consideration in lending or leasing transactions, or (iii) to any person or entity pursuant to an arrangement that the ImmuMetrix’s Board of Directors determines in good faith is a strategic partnership, licensing transaction or other arrangement which is not primarily for the purpose of raising capital. In the event of the closing of a firm commitment underwritten public offering, the rights granted in Sections 7.12 and 7.13 will terminate (in addition to any earlier termination pursuant to their terms) immediately before such closing. The rights granted in Section 7.13 will also terminate upon a bona-fide acquisition of ImmuMetrix by a third party if the

Page 10 of 32

S09-367 : GWK

acquisition is deemed by ImmuMetrix’s Board of Directors to be in the best interest of its stockholders and the acquisition results in the termination of all such similar rights held by its stockholders in connection with the acquisition.

7.15 Repurchase Obligation. If Stanford is to conduct any clinical trial on behalf of ImmuMetrix or any agent of ImmuMetrix, ImmuMetrix will repurchase all Stanford’s equity interest in ImmuMetrix prior to beginning such trial, if requested by Stanford. The repurchase price for any such equity interest will be the fair market value for that equity at the time ImmuMetrix and Stanford enter into a definitive agreement under which any such clinical research will be performed. Fair market value of publicly traded equity instruments will be determined by taking the average of the closing price for such equity over the five days preceding such date. Fair market value of non-public equity instruments will be at least as high as the greater of:

(A) the last value placed on any such equity in ImmuMetrix through an arms-length transaction regarding the issuance or sale of any equity in ImmuMetrix; or

(B) the last value placed on any such equity by ImmuMetrix’s Board of Directors in connection with any transaction other than this repurchase of shares from Stanford.

7.16 Equity Interest. As further consideration for the license granted hereunder and the restatement of the Sequencing Agreement and the PCR Agreement into this Restated Agreement, ImmuMetrix shall, subject to the approval of ImmuMetrix’s Board of Directors and Stanford’s execution and delivery to ImmuMetrix of ImmuMetrix’s standard form of stock purchase agreement attached hereto as Appendix E, grant to Stanford 700,000 shares of common stock in ImmuMetrix. When issued, those shares will represent 1.451% of the common stock in ImmuMetrix on a Fully Diluted Basis. ImmuMetrix agrees to provide Stanford with a capitalization table upon which the above calculation is made. ImmuMetrix will, subject to each inventor’s execution and delivery to ImmuMetrix of ImmuMetrix’s standard form of stock purchase agreement attached hereto as Appendix E, issue 28.34% of all shares granted to Stanford pursuant to this Section 7.16 directly to and in the name of the inventors listed allocated as stated below:

A) Xxxxxxx Xxxxx — 66,127 shares

B) Xxxxxx Xxxxxx — 66,127 shares

C) Xxxxxx Xxxxxxxxx- 66,127 shares

8 ROYALTY REPORTS, PAYMENTS, AND ACCOUNTING

8.1 Quarterly Earned Royalty Payment and Report. Beginning with the first sale of a Licensed Product by ImmuMetrix or a sublicensee, ImmuMetrix will submit to Stanford a written report (even if there are no sales) and an earned royalty payment within 30 days after the end of each calendar quarter. This report will be in the form of Appendix B and will state the number, description, and aggregate Net Sales of Licensed Product during the completed calendar quarter. The report will include an overview of the process and documents relied

Page 11 of 32

S09-367 : GWK

upon to permit Stanford to understand how the earned royalties are calculated. With each report ImmuMetrix will include any earned royalty payment due Stanford for the completed calendar quarter (as calculated under Section 7.4).

8.2 No Refund. In the event that a validity or non-infringement challenge of a Licensed Patent brought by ImmuMetrix is successful, ImmuMetrix will have no right to recoup any royalties paid before or during the period challenge.

8.3 Termination Report. ImmuMetrix will pay to Stanford all applicable royalties and submit to Stanford a written report within 90 days after the license terminates.

8.4 Accounting. ImmuMetrix will maintain records showing manufacture, importation, sale, and use of a Licensed Product for 7 years from the date of sale of that Licensed Product. Records will include general-ledger records showing cash receipts and expenses, and records that include: production records, customers, invoices, serial numbers, and related information in sufficient detail to enable Stanford to determine the royalties payable under this Agreement.

8.5 Audit by Stanford. ImmuMetrix will allow Stanford or its designee to examine ImmuMetrix’s records to verify payments made by ImmuMetrix under this Agreement.

8.6 Paying for Audit. Stanford will pay for any audit done under Section 8.5. But if the audit reveals an underreporting of earned royalties due Stanford of 5% or more for the period being audited, ImmuMetrix will pay the audit costs.

8.7 Self-audit. ImmuMetrix will conduct an independent audit of sales and royalties at least every 2 years if annual sales of Licensed Product are over $5,000,000. The audit will address, at a minimum, the amount of gross sales by or on behalf of ImmuMetrix during the audit period, the amount of funds owed to Stanford under this Agreement, and whether the amount owed has been paid to Stanford and is reflected in the records of ImmuMetrix. ImmuMetrix will submit the auditor’s report promptly to Stanford upon completion. ImmuMetrix will pay for the entire cost of the audit.

14 PROSECUTION AND PROTECTION OF PATENTS

14.1 Patent Prosecution. Following the Original Sequencing Effective Date, Stanford will be responsible for preparing, filing, and prosecuting broad patent claims (including any interference or reexamination actions) for Stanford’s benefit in the Licensed Territory and for maintaining all Licensed Patents. Stanford will notify ImmuMetrix before taking any substantive actions in prosecuting the claims, and Stanford will have final approval on how to proceed with any such actions.

14.2 Patent Costs. Within 30 days after receiving a statement from Stanford, ImmuMetrix will reimburse Stanford for all Licensed Patent’s patenting expenses, including any interference or reexamination matters, (“Patent Costs”) incurred by Stanford after the Restatement Effective Date.

14.4 ImmuMetrix Suit. ImmuMetrix, itself or through a designee, has the first right to institute suit, or defend any action for declaratory judgment, relating to the Licensed Patents and may name Stanford, subject to the requirements of this Section 14.4, as a party for standing purposes. If ImmuMetrix decides to institute suit, it will notify Stanford in writing. ImmuMetrix will bear the entire cost of the litigation. Stanford may be named as a party in a suit initiated by ImmuMetrix (other than in accordance with Section 14.5) only if:

(A) ImmuMetrix’s and Stanford’s counsel recommend that such action is necessary in their reasonably opinion to achieve standing or a court has required or will require such joinder to pursue the action.

(B) Stanford is not the first name party in the action; and

(A) prosecute the suit in both their names;

(B) bear the out-of-pocket costs equally;

(D) agree how they will exercise control over the action.

Page 15 of 32

S09-367 : GWK

14.6 Stanford Suit. If ImmuMetrix does not initiate an enforcement action within 120 days of a request by Stanford to do so or ImmuMetrix does not elect to control a declaratory judgment action within 90 days of receiving notice that such action has been filed, Stanford may institute and prosecute a suit so long as it conforms with the requirements of this Section. Stanford will diligently pursue the suit and will bear the entire cost of the litigation, including expenses and counsel fees incurred by ImmuMetrix. Stanford will keep ImmuMetrix reasonably apprised of all developments in the suit, and will seek ImmuMetrix’s input and approval on any substantive submissions or positions taken in the litigation regarding the scope, validity and enforceability of the Licensed Patent. Stanford will not prosecute, settle or otherwise compromise any such suit in a manner that adversely affects ImmuMetrix’s interests without ImmuMetrix’s prior written consent.

14.7 Recovery. If ImmuMetrix sues under Section 14.4, then any recovery in excess of any unrecovered litigation costs and fees will be shared with Stanford as follows:

(A) any payment for past sales will be deemed Net Sales, and ImmuMetrix will pay Stanford royalties at the rates specified in Section 7.4;

(B) any payment for future sales will be deemed a payment under a Sublicense, and royalties will be shared as specified in Article 4.

(C) ImmuMetrix and Stanford will negotiate in good faith appropriate compensation to Stanford for any non-cash settlement or non-cash cross-license.

14.8 Abandonment of Suit. If either Stanford or ImmuMetrix commences a suit and then wants to abandon the suit, it will give timely notice to the other party. The other party may continue prosecution of the suit after Stanford and ImmuMetrix agree on the sharing of expenses and any recovery in the suit.

14.9 Cooperation. The non-controlling party shall, at the reasonable request and expense of the party controlling any enforcement or declaratory action under this Article 14, fully cooperate with the controlling party, including making available relevant records, papers, information, samples, specimens, and the like. The party controlling the enforcement or declaratory action shall keep the non-controlling party reasonably informed of the progress of such action, and the non-controlling party shall have the right to participate in such enforcement or declaratory action with counsel of its own choice at its own expense.

This Common Stock Purchase Agreement (the “Agreement”) is entered into by and between ImmuMetrix, Inc. (the “Company”) and                     (the “Purchaser”) as of             , 2013 (the “Effective Date”).

1 Sale of Shares. The Company will issue and sell to the Purchaser             shares of the Company’s fully paid and nonassessable Common Stock (the “Shares”) pursuant to Section 7.16 of that certain Amended and Restated Exclusive Agreement dated                     by and between the Purchase and the Company (the “License Agreement”).

2 Closing; Delivery.

2.1 Closing. The closing of the purchase and sale of the Shares to the Purchaser hereunder shall be held at the offices of Xxxxxx Xxxxxxx Xxxxxxxx and Xxxxxx, 000 Xxxx Xxxx Xxxx, Xxxx Xxxx, Xxxxxxxxxx 00000-0000 on the Effective Date (the “Closing”). The Closing shall be contingent upon the Purchaser executing and delivering the License. Within a reasonable time after the Closing, the Company will issue a stock certificate, registered in the name of the Purchaser, reflecting the Shares.

2.2 Delivery. At the Closing, the Company will deliver to the Purchaser a certificate representing the Shares against the execution and delivery to the company of the License Agreement by Purchaser. If the Purchaser is not in attendance at the Closing, such delivery shall be via U.S. mail to the address shown under the Purchaser’s name on the signature page to this Agreement.

3 Company Representations. The Company hereby represents and warrants to the Purchaser as of the date hereof as follows:

3.1 Organization and Standing. The Company is a corporation duly organized, validly existing, and in good standing under the laws of the State of Delaware. The Company has all requisite corporate power and authority to own and operate its properties and assets and to carry on its business as presently conducted.

3.2 Corporate Power. The Company has all requisite legal and corporate power to execute and deliver this Agreement, to sell and issue the Shares hereunder, and to carry out and perform its obligations under the terms of this Agreement.

3.3 Authorization. All corporate action on the part of the Company, its officers, directors and stockholders necessary for the authorization, execution, delivery and performance by the Company of this Agreement, the authorization, issuance, sale and delivery of the Shares, and the performance of the Company’s obligations hereunder has been taken or will be taken prior to the Closing. This Agreement, when executed and delivered by the Company, shall constitute a valid and legally binding obligation of the Company enforceable in accordance with its respective terms, subject to laws of general application relating to bankruptcy, insolvency and the relief of debtors and rules of law governing specific performance, injunctive relief or other equitable remedies. The Shares, when issued in compliance with the provisions of

Page 26 of 32

S09-367 : GWK

this Agreement, will be validly issued, fully paid and nonassessable, and the Shares will be free of any liens or encumbrances created by the Company; provided, however, that the Shares may be subject to restrictions on transfer under applicable securities laws as set forth herein.

4 Purchaser Representations, Warranties and Covenants. In connection with the purchase of the Shares, the Purchaser represents and warrants to the Company as follows:

4.1 The Purchaser is aware of the Company’s business affairs and financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the securities. The Purchaser is purchasing these securities for investment for the Purchaser’s own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933 (the “Securities Act”). The Purchaser is an “accredited investor” within the meaning of SEC Rule 501 of Regulation D, as presently in effect.

4.2 The Purchaser understands that the securities have not been registered under the Securities Act by reason of a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of the Purchaser’s investment intent as expressed herein. In this regard, the Purchaser understands that, in view of the Securities and Exchange Commission (“Commission”), the statutory basis for such exemption may not be present if the Purchaser’s representations meant that the Purchaser’s present intention was to hold these securities for a minimum capital gains period under the tax statutes, for a deferred sale, for a market rise, for a sale if the market does not rise, or for a year or any other fixed period in the future.

4.3 The Purchaser further acknowledges and understands that the securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. The Purchaser further acknowledges and understands that the Company is under no obligation to register the securities. The Purchaser understands that the certificate evidencing the securities will be imprinted with a legend which prohibits the transfer of the securities unless they are registered or such registration is not required in the opinion of counsel for the Company.

4.4 The Purchaser is aware of the adoption of Rule 144 by the Commission, promulgated under the Securities Act, which permits limited public resale of securities acquired in a non-public offering subject to the satisfaction of certain conditions.

4.5 The Purchaser further acknowledges that in the event all of the requirements of Rule 144 are not met, compliance with Regulation A or some other registration exemption will be required; and that although Rule 144 is not exclusive, the staff of the Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and other than pursuant to Rule 144 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales and that such persons and the brokers who participate in the transactions do so at their own risk.

4.6 The Purchaser understands that the share certificate evidencing the Shares issued hereunder shall be endorsed with the following legends:

(A) THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE

Page 27 of 32

S09-367 : GWK

SALEOR DISTRIBUTION THEREOF. THES ECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION OTHERWISE COMPLIES WITH THE ACT.

(B) THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER, A RIGHT OF FIRST REFUSAL AND A LOCK-UP PERIOD IN THE EVENT OF A PUBLIC OFFERING HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE STOCK PURCHASE AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS, RIGHT OF FIRST REFUSAL AND LOCK-UP PERIOD ARE BINDING ON TRANSFEREES OF THESE SHARES.

(C) Any legend required to be placed thereon by applicable federal state securities laws, or the terms of this Agreement.

0 Xxxxxx Xxxxxxxx Xxxxxxxx. Purchaser shall not sell or otherwise transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, of any Common Stock (or other securities) of the Company held by Purchaser (other than those included in the registration) during the period from the filing of the registration statement for the Company’s Initial Public Offering filed under the Securities Act that includes securities to be sold on behalf of the Company to the public in an underwritten public offering under the Securities Act through the end of the one hundred and eighty (180) day period following the effective date of the registration statement (or such other period as may be requested by the Company or an underwriter to accommodate regulatory restrictions on (i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(0(4) or NYSE Rule 472(0(4), or any successor provisions or amendments thereto), provided that all officers and directors of the Company are bound by and have entered into similar agreements and the Company uses all reasonable efforts to have all holders of at least one percent (1%) of the Company’s voting securities be bound by and enter into similar agreements.

6 Company’s Right of First Refusal. Before any Shares acquired by the Purchaser pursuant to this Agreement (or any beneficial interest in such Shares) may be sold, gifted, transferred, encumbered or otherwise disposed of in any way (whether by operation of law or otherwise) by the Purchaser or any subsequent transferee (each a “Holder”), such Holder must first offer such Shares or beneficial interest to the Company and/or its assignee(s) as follows:

6.1 Notice of Proposed Transfer. The Holder shall deliver to the Company a written notice stating: (a) the Holder’s bona fide intention to sell or otherwise transfer the Shares; (b) the name of each proposed transferee; (c) the number of Shares to be transferred to each proposed transferee; (d) the bona fide cash price or other consideration for which the Holder proposes to transfer the Shares; and (e) that by delivering the notice, the Holder offers all such Shares to the Company and/or its assignee(s) pursuant to this Section and on the same terms described in the notice.

6.2 Exercise of Right of First Refusal. At any time within 30 days after receipt of the Holder’s notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the proposed transferees, at the purchase price determined in accordance with Section 6.3.

6.3 Purchase Price. The purchase price for the Shares purchased by the Company and/or its assignee(s) under this Section shall be the price listed in the Holder’s notice. If the price listed in the Holder’s notice includes consideration other than cash, the cash equivalent value of the non-cash consideration shall be determined by the Board of Directors of the Company in its sole discretion.

6.4 Payment. Payment of the purchase price shall be made, at the option of the Company and/or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company and/or its assignee(s), or by any combination thereof within 30 days after receipt by the Company of the Holder’s notice (or at such later date as is called for by such notice).

6.5 Holder’s Right to Transfer. If all of the Shares proposed in the notice to be transferred to a given proposed transferee are not purchased by the Company and/or its assignee(s) as provided in this Section, then the Holder may sell or otherwise transfer such Shares to that proposed transferee, provided that: (a) the transfer is made only on the terms provided for in the notice, with the exception of the purchase price, which may be either the price listed in the notice or any higher price; (b) such transfer is consummated within 60 days after the date the notice is delivered to the Company; (c) the transfer is effected in accordance with any applicable securities laws, and if requested by the Company, the Holder shall have delivered an opinion of counsel acceptable to the Company to that effect; and (d) the proposed transferee agrees in writing that the provisions of this Section shall continue to apply to the transferred Shares in the hands of such proposed transferee. If any Shares described in a notice are not transferred to the proposed transferee within the period provided above, then before any such Shares may be transferred, a new notice shall be given to the Company, and the Company and/or its assignees shall again be offered the right of first refusal described in this Section.

6.6 Exception for Certain Transfers. Notwithstanding anything to the contrary contained elsewhere in this Section, the transfer of any or all of the Shares by the Purchaser to his spouse, ex-spouse, domestic partner, lineal descendant or antecedent, brother or sister, the adopted child or adopted grandchild, or the spouse or domestic partner of any child, adopted child, grandchild or adopted grandchild of the Purchaser, or to one or more trusts, retirement accounts, or other estate planning vehicles for the exclusive benefit of Purchaser or those members of Purchaser’s family specified in this Section, shall be exempt from the provisions of this Section; provided that, in each such case, the transferee(s) shall agree in writing to receive and hold the Shares so transferred subject to all of the provisions of this Agreement, including but not limited to this Section, and there shall be no further transfer of such Shares except in accordance with the terms of this Section.

I understand, acknowledge and agree that completion and delivery of this Letter of Transmittal constitutes assent to the terms of the transactions contemplated by the Merger Agreement. I have reviewed and understand the escrow and indemnification provisions of Article VII of the Merger Agreement, and my signature to this Letter of Transmittal and tender of my ImmuMetrix Certificates constitute my agreement to be bound by Article VII of the Merger Agreement as an Indemnifying Securityholder (as defined in the Merger Agreement). I understand that, pursuant to the Merger Agreement, of the aggregate Merger Consideration (i) an aggregate amount of [5,722,788] shares of CareDx Series G Preferred Stock will be payable to the stockholders of ImmuMetrix upon closing of the Merger, (ii) an aggregate amount of [1,560,760] shares of CareDx Series G Preferred Stock will be payable to the stockholders of ImmuMetrix upon satisfaction of certain conditions, and (ii) an aggregate amount of [520,253] shares of CareDx Series G Preferred Stock will be withheld from the stockholders of ImmuMetrix to secure in part the indemnification obligations of the stockholders of ImmuMetrix to CareDx pursuant to Article VII of the Merger Agreement.

The Merger Agreement contemplates that after the effective time of the Merger (the “Effective Time”), CareDx will make the necessary payments of the Merger Consideration upon the surrender by stockholder of ImmuMetrix (an “ImmuMetrix Stockholder”) of each of such holder’s ImmuMetrix Certificates. I acknowledge that, until surrendered, (i) each outstanding ImmuMetrix Certificate that formerly represented shares of ImmuMetrix capital stock will be deemed from and after the Effective Time, for all corporate purposes to evidence only the right to receive the Merger Consideration.

I also understand and acknowledge that all questions as to the validity, form and eligibility of any shares of ImmuMetrix capital stock surrendered hereby shall be determined by CareDx in its reasonable discretion. I further acknowledge and agree that the Merger Consideration issued in exchange for shares of ImmuMetrix capital stock shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of ImmuMetrix capital stock.

By completion and delivery of this Letter of Transmittal, I hereby expressly represent and warrant to CareDx as follows:

(i) I am the registered holder of the shares of ImmuMetrix capital stock represented by any ImmuMetrix Certificate listed above in Box A, with good title to, and full power and authority to sell, assign and transfer, such shares, free and clear of all liens, claims and encumbrances, and not subject to any adverse claims.

I hereby acknowledge that I have carefully read this Letter of Transmittal and further acknowledge that I have had the opportunity to consult with an attorney and financial and/or tax advisor of my own choosing regarding the information contained herein and the transactions contemplated hereby.

Re: CareDx, Inc. – Lock-Up Agreement (the “Agreement”)

Dear Sirs:

As an inducement to the underwriters (the “Underwriters”) to execute an Underwriting agreement (the “Underwriting Agreement”) providing for a public offering (the “Offering”) of common stock (the “Common Stock”), of CareDx, Inc., a Delaware corporation, and any successor (by merger, change of name or otherwise) thereto (the “Company”), the undersigned hereby agrees that without, in each case, the prior written consent of Xxxxx Xxxxxxx & Co. and Leerink Partners LLC (the “Representatives”) during the period specified in the second succeeding paragraph (the “Lock-Up Period”), the undersigned will not: (1) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, make any short sale or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into, exercisable or exchangeable for or that represent the right to receive Common Stock (including without limitation, Common Stock which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission, securities which may be held as a custodian and securities which may be issued upon exercise of a stock option or warrant) whether now owned or hereafter acquired (the “Undersigned’s Securities”); (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Undersigned’s Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise; (3) make any demand for or exercise any right with respect to, the registration of any Common Stock or any security convertible into or exercisable or exchangeable for Common Stock; or (4) publicly disclose the intention to do any of the foregoing.

The undersigned agrees that the foregoing restrictions preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be

expected to lead to or result in a sale or disposition of the Undersigned’s Securities even if such Securities would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned’s Securities or with respect to any security that includes, relates to, or derives any significant part of its value from the Undersigned’s Securities.

The Lock-Up Period will commence on the date of this Agreement and continue and include the date 180 days after the date of the final prospectus used to sell Common Stock in the Offering pursuant to the Underwriting Agreement.

If the undersigned is an officer or director of the Company, (i) the Representatives agree that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of shares of Common Stock, the Representatives will notify the Company of the impending release or waiver, and (ii) the Company has agreed in the Underwriting Agreement to announce the impending release or waiver by issuing a press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by the Representatives hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if both (a) the release or waiver is effected solely to permit a transfer not for consideration, and (b) the transferee has agreed in writing to be bound by the same terms described in this letter that are applicable to the transferor, to the extent and for the duration that such terms remain in effect at the time of the transfer. The undersigned further agrees that the foregoing provisions shall be equally applicable to any issuer-directed Common Stock that the undersigned may purchase in the offering.

Notwithstanding the foregoing, the undersigned may transfer the Undersigned’s Securities (i) as a bona fide gift or gifts, (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, (iii) if the undersigned is a corporation, partnership, limited liability company, trust or other business entity (1) transfers to another corporation, partnership, limited liability company, investment fund, trust or other business entity that is a direct or indirect affiliate (as defined in Rule 405 promulgated under the Securities Act of 1933, as amended) of the undersigned or (2) distributions of shares of Common Stock or any security convertible into or exercisable for Common Stock to limited partners, limited liability company members or stockholders of the undersigned, (iv) if the undersigned is a trust, transfers to the beneficiary of such trust, (v) transfers by testate succession or intestate succession or (vi) pursuant to the Underwriting Agreement; provided, in the case of clauses (i)-(v), that (x) such transfer shall not involve a disposition for value, (y) the transferee agrees in writing with the Underwriters to be bound by the terms of this Lock-Up Agreement, and (z) no filing by any party under Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), shall be required or shall be made voluntarily in connection with such transfer. For purposes of this Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.

In addition, the foregoing restrictions shall not apply to (i) the exercise (including by means of a cashless exercise) of stock options granted pursuant to the Company’s equity incentive plans; provided that it shall apply to any of the Undersigned’s Securities issued upon such exercise, (ii) the establishment of any contract, instruction or plan (a “Plan”) that satisfies all of the requirements of

Rule 10b5-1(c)(1)(i)(B) under the Exchange Act; provided that no sales of the Undersigned’s Securities shall be made pursuant to such a Plan prior to the expiration of the Lock-Up Period, and such a Plan may only be established if no public announcement of the establishment or existence thereof and no filing with the Securities and Exchange Commission or other regulatory authority in respect thereof or transactions thereunder or contemplated thereby, by the undersigned, the Company or any other person, shall be required, and no such announcement or filing is made voluntarily, by the undersigned, the Company or any other person, prior to the expiration of the Lock-Up Period, or (iii) transactions related to shares of Common Stock or other securities acquired in open market transactions after the completion of the Offering; provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made during the Lock-Up Period in connection with subsequent sales of Common Stock or other securities acquired in such open market transactions.

In furtherance of the foregoing, the Company and its transfer agent and registrar are hereby authorized to decline to make any transfer of shares of Common Stock if such transfer would constitute a violation or breach of this Agreement.

Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Agreement and that upon request, the undersigned will execute and additional documents necessary to ensure the validity or enforcement of this Agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

The undersigned understands that the undersigned shall be released from all obligations under this Agreement if (i) the Company notifies the Underwriters that it does not intend to proceed with the Offering, (ii) the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Stock to be sold thereunder, or (iii) the Offering is not completed by December 31, 2014.

The undersigned understands that the Underwriters are entering into the Underwriting Agreement and proceeding with the Offering in reliance upon this Agreement.

This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

Very truly yours,

NONCOMPETITION AND NONSOLICITATION AGREEMENT

THIS NONCOMPETITION AND NONSOLICITATION AGREEMENT (this “Agreement”) is made and entered into as of May [    ], 2014 by and between CareDx, Inc., a Delaware corporation (“Purchaser”), and [Newco, Inc.], a Delaware corporation (“Newco”). Capitalized terms used in this Agreement but not otherwise defined herein have the meanings assigned to them in the Merger Agreement (as defined below).

RECITALS

A. Concurrently with the execution of this Agreement, Purchaser, Monitor Acquisition Corporation, a Delaware corporation and wholly-owned subsidiary of Purchaser (“Merger Sub”), ImmuMetrix, Inc. (the “Company”) and Xxxxxxx Xxxxxxx as the Holders’ Agent, have entered into an Agreement and Plan of Merger, dated as of May 17, 2014 (the “Merger Agreement”), pursuant to which Merger Sub shall merge with and into the Company (the “Merger”).

B. In connection with the Merger and prior to the closing of the Merger, Newco and Company will enter into an Asset Transfer Agreement, dated as of May     , 2014 (the “ATA”), pursuant to which the Company will transfer certain Transferred Assets of the Company (described in the ATA).

C. It is a condition to the Parties’ (as defined in the Merger Agreement) obligations to the Merger Agreement that Newco enter into this Agreement.

NOW, THEREFORE, in consideration of the premises, the mutual promises hereinafter set forth, and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties hereto agree as follows:

AGREEMENT

1. Effectiveness. This Agreement shall be effective as of the Closing (as defined in the Merger Agreement). To the extent the Merger Agreement is terminated for any reason prior to the Closing, this Agreement shall immediately upon termination of the Merger Agreement terminate in its entirety without ever having become effective and it shall be null and void in all respects.

2. Definitions. For purposes of this Agreement:

(a) “Closing Date” means the date on which the Closing occurs.

(b) “Restricted Business” means the development, commercialization, licensing, marketing or sale of products or services that utilize either cell-free DNA detection or immune repertoire profiling (“cfDNA/IR Products”) specifically for the diagnosis and clinical management of solid organ and bone marrow transplant recipients or pre-transplant patients who are on a designated transplant waiting list (“Transplant Patients”), but excluding the detection, diagnosis or clinical management of cancer, or conditions that are a precursor to cancer.

(c) Restricted Business does not include the development, commercialization, licensing or sale of cfDNA/IR Products for the non-transplant patient population that also have utility for transplant patients (such as a diagnostic for infectious disease intended for a non-transplant patient population but which is useful also for transplant recipients) and are sold to or used by

Transplant Patients, provided that such products are not marketed specifically for use by transplant or pre-transplant patients. For avoidance of doubt, Restricted Business does include (i) development, commercialization, licensing or sale of products used for assessing whether a solid organ transplant or bone marrow transplant is or will be rejected, (ii) developing products targeted specifically at transplant recipients.

(d) “Restricted Employee” mean the current and future employees of Purchaser and Company.

(e) “Restricted Territory” means each and every country, province, state, city, or other political subdivision of the world in which the Company or any of its subsidiaries or affiliates is currently engaged, or currently plans to engage in a Restricted Business.

(f) “Restriction Period” means (i) with respect to the obligations in Section 3(a), the period from the Closing Date until three (3) years after the Closing Date, and (ii) with respect to the obligations in Section 3(b), the period from the Closing Date until one (1) year after the Closing Date.

3. Noncompetition; Nonsolicitation.

(a) During the Restriction Period, Newco shall not in any manner within the Restricted Territory, directly or indirectly through its officers, employees, agents and representatives, engage in the Restricted Business. Newco shall further refrain from, including through persons or entities that Newco directly or indirectly controls, intentionally enabling or assisting third parties (other than Purchaser or the Company) to engage in the Restricted Business. Notwithstanding anything to the contrary in this Section 3(a) or elsewhere in this Agreement, in the event of a Change in Control (as defined below), the restrictions set forth in this Section 3(a) with respect to engaging in the Restricted Business shall apply only to Newco or members of the Newco Company Group and shall not apply to the rest of the entity acquiring Newco (the “Acquiror”) or any member of the Acquiring Company Group, so long as the Acquiror or member of the Acquiring Company Group does not make material use of the of the Transferred Intellectual Property (as defined in the ATA) and proprietary know-how of Newco (“Segregated Technology”) in developing or commercializing cfDNA/IR Products. Notwithstanding the foregoing, if rights to Segregated Technology were granted to the Acquiror in compliance with this Section 3(a) prior to and independently of Acquiror’s acquisition of Newco, then the use of such Segregated Technology in accordance with such grant shall not be deemed use of Segregated Technology for purposes of this Section 3(a).

(b) During the Restriction Period, Newco shall not, directly or indirectly (including without limitation through any affiliate of Newco or any other person) solicit, attempt to solicit or encourage any Restricted Employee to leave his or her employment, consulting or independent contractor relationship with the Company or the Purchaser or any other of Purchaser’s affiliates.

(c) As used in this section, “Acquiring Company Group” means all affiliates of the Acquiror immediately prior to Acquiror’s acquisition of Newco; “Newco Company Group” means Newco, together with any entity that was its affiliate immediately prior to the acquisition of Newco by the Acquiror, and “Change in Control” means the consummation of a merger or consolidation of Newco with any other corporation or entity, other than a merger or consolidation which would result in the voting securities of Newco outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) more than fifty percent (50%) of the total voting power represented by the voting securities of Newco or such surviving entity outstanding immediately after such merger or consolidation, or the consummation of the sale or disposition by Newco of all or substantially all of Newco’s assets.

(d) Newco will not hinder the Purchaser’s efforts to obtain access to the Quake/Valentine tissue samples and other transplant tissue samples held by Stanford and used in the Company’s research activities.

2

4. Understanding of Covenants.

(a) Newco acknowledges and agrees that Newco (i) is familiar with and has carefully considered the covenants set forth above in this Agreement, (ii) is fully aware of Newco’s obligations hereunder, (iii) is in possession of the Confidential Information, and pursuant to the ATA following the Closing Date will continue to have access to Confidential Information, (iv) understands that one of the material inducements for Purchaser to enter into the Merger Agreement and performance of its obligations thereunder, including making a cash contribution to Newco, (v) Newco agrees that the restrictions set forth herein are reasonable in consideration of the benefits Newco will receive pursuant to the Merger Agreement and the ATA, (vi) agrees that Company currently conducts, or is planning to conduct, business throughout the United States and worldwide, and (vii) that such covenants are separately bargained-for consideration and are material inducements to Purchaser to enter into the Merger Agreement.

(b) Newco agrees that the covenants set forth above in this Agreement do not confer a benefit upon Company disproportionate to the detriment of Newco. Newco represents that the execution of this Agreement, and the performance of Newco’s obligations under this Agreement, do not and will not conflict with, or result in a violation or breach of, any other agreement to which Newco is a party or any judgment, order or decree to which Newco is subject. Newco represents that Newco has all necessary authority to execute this Agreement.

5. Injunctive Relief. Each Party agrees that any breach by the other of this Agreement would cause immediate and irreparable harm to the non-breaching Party, that such harm would be difficult or impossible to measure, and that damages for the non-breaching Party would therefore be an inadequate remedy for any such breach. Therefore, each Party agrees that in the event of a breach or threatened breach of this Agreement, Purchaser or Newco (whichever is seeking to enforce this Agreement) shall be entitled to seek an injunction restraining the Party in breach (or threatened to be in breach, as the case may be) from the conduct which would constitute a breach of this Agreement, specific performance and/or other appropriate relief in order to enforce and prevent any violations of this Agreement.

6. Non-Exclusive. The rights and remedies of Purchaser hereunder are not exclusive of or limited by any other rights or remedies that Purchaser may have, whether at law, in equity, by contract or otherwise. Without limiting the generality of the foregoing, the rights and remedies of Purchaser hereunder, and the obligations and liabilities of Newco hereunder, are in addition to their respective rights, remedies, obligations and liabilities under the law of unfair competition, misappropriation of trade secrets and the like. This Agreement does not limit Newco’s obligations or Purchaser’s rights (or any present or future affiliate of Purchaser) under the terms of any other agreement between Newco and Purchaser or Company.

7. Notices. All notices, requests, demands, claims, consents and other communications that are required or otherwise delivered hereunder shall be in writing and shall be deemed to have been duly given if (a) personally delivered; (b) sent by nationally recognized overnight courier; (c) mailed by registered or certified mail with postage prepaid, return receipt requested; or (d) transmitted by facsimile or telecopy (with a copy of such transmission

8. Governing Law; Disputes; Consent to Jurisdiction.

(a) Governing Law. This Agreement shall be governed by and construed in accordance with the domestic Laws of the State of California without giving effect to any choice of law or conflict of law provision or rule (whether of the State of California or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of California.

(b) Consent to Jurisdiction. Each of the Parties hereto hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of any California state court, or, if no such state court has proper jurisdiction, the Federal court of the United States of America, sitting in Santa Xxxxx County, California, and any appellate court from any thereof, in any Legal Proceeding arising out of or relating to this Agreement or for recognition or enforcement of any judgment relating thereto.

9. Amendments, Modifications and Waivers. No amendment, modification or waiver of any provision of this Agreement shall be valid unless the same shall be in writing and signed by authorized officer of Purchaser and Newco. No waiver by Purchaser of any default, misrepresentation or breach hereunder by Newco, whether intentional or not, shall be deemed to extend to any prior or subsequent default, misrepresentation or breach hereunder by Newco.

10. Independent Counsel. Each Party acknowledges that it has been represented by independent counsel of its choice, or has had the opportunity to be represented by independent counsel of its choice, and that to the extent, if any, that it desired, has availed itself of this right and opportunity throughout all negotiations that have preceded the execution of this Agreement, and that it has executed the same with the consent and upon the advice of such independent counsel. Accordingly, any rule of law or any legal decision that would require interpretation of any claimed ambiguities in this Agreement against the drafting Party has no application and is expressly waived.

4

11. Integration. This Agreement is based on the premises and mutual promises contained herein and also upon the ATA and Merger Agreement. This Agreement, and the ATA and Merger Agreement upon which this Agreement is based, are the entire agreement of the parties pertaining to the subject matter of this Agreement, and all prior or contemporaneous negotiations, agreements, understandings, or representations, whether written or oral, that pertain to the subject matter of this Agreement, are expressly superseded hereby and are of no further force and effect. Each of the parties acknowledges that it has not relied on any promise, representation or warranty, expressed or implied, not contained in this Agreement, the ATA or the Merger Agreement. Newco understands and agrees that he has had an opportunity to seek his own counsel in his review of this Agreement.

12. Assignment. This Agreement shall inure to the benefit of and be binding upon the Parties and their respective successors, assigns, heirs and/or personal representatives, provided that neither this Agreement nor any interest herein shall be assigned or otherwise transferred, by operation of law or otherwise, by either Party without the prior written consent of the other Party (which consent shall not be withheld unreasonably). Notwithstanding the foregoing, either Party may assign this Agreement, without the written consent of the other Party, (a) to an Affiliate to whom the ATA is assigned, provided that the assigning Party guarantees the performance of this Agreement by such Affiliate, or (b) to a successor to all or substantially all of such assigning Party’s assets (whether by asset purchase, merger or otherwise), provided that any such assignee agrees in writing to be bound by the terms of this Agreement. Any assignment of this Agreement in contravention of this Section 12 shall be null and void. Nothing in this Agreement shall confer, whether expressly or by implication, any rights or remedies under or by reason of this Agreement on any person or entity other than the Parties, affiliates of Purchaser and the respective permitted successors and assigns of any of the foregoing.

13. 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 hereto. Upon such determination that any such provision is illegal, void or unenforceable, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner to the fullest extent permitted by applicable law.

14. Counterparts; Signatures. The Parties may execute this Agreement in counterparts, each of which shall be deemed to be an original instrument, but both of which together shall constitute but one agreement. The delivery of a signature to this Agreement by facsimile or electronic mail shall be sufficient for all purposes between the Parties.

For purposes of this letter, a “Closed Session” shall mean that part of any meeting or teleconference of the Board of Directors where a majority of the Board of Directors determines in good faith that (i) the exclusion of observers is necessary to preserve the attorney-client privilege, (ii) to protect trade secrets or (iii) access to such information or attendance at such meeting would result in a conflict of interest between Observer and the Company.

2. The rights set forth in this letter shall terminate upon (i) Liquidation Event (as defined in the Company’s Amended and Restated Certificate of Incorporation); (ii) upon the closing of a firm commitment underwritten public offering pursuant to an effective registration statement on Form S-1 or any successor form under the Securities Act of 1933, as amended, covering the offer and sale of the common stock of the Company for the account of the Company to the public with gross proceeds to the Company in excess of $30,000,000, or (iii) removal and replacement of Observer by the Holders’ Agent, in which case the new observer shall be entitled to all the rights set forth herein as if such new observer were the original Observer party hereto.

3. The Observer acknowledges that the information received by Observer pursuant to this letter agreement shall be treated as confidential information of the Company under the terms of the Consulting Agreement between the Company and the Observer.

IN WITNESS WHEREOF, the parties hereto have executed this Letter as of the date first written above.
