Purchaser, and Purchaser shall purchase from the Seller, all of the Purchased Assets (other than those Purchased Assets that are contributed
by the Seller to the Company pursuant to the Contribution Agreement entered into between the Seller and the Company as of immediately
prior to the Closing as described therein), in each case, free and clear of all Liens other than Permitted Liens, provided, however,
that, no later than ten Business Days prior to the Closing, Purchaser may provide to the Seller the Alternate Transferee List, and the
Seller shall then assign, transfer and convey any of the Purchased Assets described in the Alternate Transferee List to the Alternate

of the Purchaser set forth in Section 2.2 and Purchaser shall be responsible for the payment of any incremental Transfer

in lieu of being transferred to the Purchaser or to the Company pursuant to the Contribution Agreement. All Excluded Assets shall be

2.2 Purchase
Price. The aggregate purchase price for all of the Purchased Assets (the “ Purchase Price ”) shall be an amount
in cash equal to $170,000,000 (One Hundred Seventy Million Dollars), payable to the Seller in accordance with the terms of this Agreement
and provided that the Purchase Price shall further be increased or decreased pursuant to Section 2.3(b)(i) of this
Agreement and the terms set forth in the Purchase Price Adjustments Schedule.

2.3 Closing
of the Transactions.

(a) The
Closing. The closing of the transactions contemplated by this Agreement (the “ Closing ”) shall take place at the
offices of CareDx, Inc. 8000 Marina Blvd, Brisbane, CA 94005, U.S.A., commencing at 10:00 a.m. local time on the tenth Business
Day following the satisfaction or waiver of all conditions of the Parties to consummate the transactions contemplated by this Agreement
(other than the conditions with respect to actions the respective Parties will take at the Closing itself), or at such other time and
place or on such other date as is mutually agreed by Purchaser and the Seller. The date of the Closing is referred to in this Agreement
as the “ Closing Date.” The effective time of the Closing for Tax, operational and all other matters shall be deemed
to be 12:01 a.m., local time, in each jurisdiction in which the Quark Business is conducted, on the Closing Date.

(b) Closing
Deliveries. Subject to the satisfaction of the conditions set forth in Article 3 of this Agreement, at or prior to the Closing:

(i) Purchaser
shall deliver to the Seller the Estimated Closing Date Payment calculated as set forth in the Purchase Price Adjustments Schedule,
by means of a wire transfer of immediately available funds to the accounts specified by the Seller and all other items required to be
delivered by Purchaser at Closing to the Seller in accordance with the terms of this Agreement.

20

(ii) the
Seller shall cause Purchaser to be listed as the owner of the Shares in the duly updated share register of the Company and deliver to
Purchaser the updated share register in original form together with any share certificate(s) in original form duly endorsed to
Purchaser, and deliver all items required to be delivered by the Seller to Purchaser at Closing as specified in Section 3.2.

(iii) At
the Closing, the Seller shall deliver to Purchaser such bills of sale, assignments, endorsements, transfer documents, assumption agreements,
and other instruments of transfer and conveyance (including, as applicable, a Bill of Sale) as are necessary to transfer to Purchaser
good and valid title to the Purchased Assets other than the Shares, free and clear of all Liens other than Permitted Liens, and to effect
the assumption by Purchaser of the Assumed Liabilities, in each case in form and substance reasonably satisfactory to Purchaser and the
Seller. The Parties shall execute and deliver such other Transaction Documents as may be necessary or appropriate to effect the transactions
contemplated by this Agreement.

(iv) At
the Closing, each of the Seller and Purchaser, and their respective Affiliates, as applicable, shall execute and deliver the Transition
Services Agreement, the Distribution Agreement, the Data Rights Agreement and the Trademark License, each in substantially the form attached
as an exhibit hereto (subject to any modifications, additions and other changes to the schedules, exhibits or annexes to the Transition
Services Agreement as may be agreed between the Seller and Purchaser during the Pre-Closing Period), and Seller shall execute and deliver
the Non-Transferred Employee Commitment Letter in substantially the form attached as an exhibit hereto.

(v) Immediately
following the Closing, Purchaser shall cause a shareholders’ meeting of the Company to be held at which Purchaser shall appoint
new directors of the Company with immediate effect, and Purchaser shall prepare the minutes of the said meeting as well as any other
ancillary documentation related thereto and shall promptly submit and file the relevant changes with respect to the directors of the
Company with the Swedish Companies Registration Office.

2.4 Assumed
Liabilities; Retention by Seller of Excluded Liabilities.

(a) Upon
the terms and subject to the conditions set forth in this Contribution Agreement, effective as of immediately prior to the Closing, the
Company (but not the Purchaser) shall enter into the Contribution Agreement with the Seller pursuant to which the Company shall agree
to accept, assume, pay, perform, fulfill and discharge when due the Assumed Liabilities, provided, however, that, with
respect solely to any Assigned Contract assigned to the Purchaser (and not to the Company), the Purchaser shall agree to accept, assume,
pay, perform, fulfill and discharge when due the Assumed Liabilities to the extent they are contractual liabilities arising out of any
such Assigned Contract (the “ Purchaser Assumed Contractual Liabilities ”).

21

(b) The
Parties agree that, except for the Assumed Liabilities, the Company shall not (and the Purchaser shall not) assume, pay, perform or discharge
or otherwise have any obligation or liability for, any Liabilities of the Seller or of any Non-Transferred Affiliate (whether now existing
or hereafter arising), and the Seller and its Non-Transferred Affiliates shall retain, and shall be solely responsible and liable for
paying, performing and discharging when due, all such Liabilities of the Seller or such Non-Transferred Affiliates (collectively, the
“ Excluded Liabilities ”). Any and all incentives, bonuses, retention payments, or other compensation due or promised
to Quark Employees or any other Person by the Seller or by any of the Quark Companies prior to the Closing as a result of or in connection
with the negotiation, execution, Closing, completion or performance of this Agreement or the Transactions and that is not otherwise included
in the calculation of the Net Cash/Net Working Capital set forth in the Purchase Price Adjustments Schedule, shall constitute
an Excluded Liability. The Non-Transferred Employee Commitment shall constitute an Excluded Liability.

2.5 Third
Party Consents.

(a) Notwithstanding
anything in this Agreement to the contrary, this Agreement shall not constitute an agreement to sell, convey, transfer, assign or deliver
to Purchaser any Purchased Asset, or any claim, right or benefit arising under or resulting from such Purchased Asset, if and for so
long as such transfer or attempted transfer to Purchaser thereof, without the Consent of a third party, under applicable Law or the express
terms of the applicable Assigned Contract, would constitute a breach or other contravention of the rights of such third party, would
be ineffective with respect to any party to an agreement concerning such Purchased Asset, or would in any material way adversely affect
the rights of the Seller or its Affiliates or, upon such transfer, of Purchaser or its Affiliates (including the Quark Companies) with
respect to such Purchased Asset (such assets being collectively referred to herein as “ Restricted Assets ”). Notwithstanding
anything in this Agreement to the contrary, unless and until any such Consent with respect to any Restricted Asset or Restricted Split
Interest (as defined in Section 2.5(c) below), as appropriate, is obtained or the applicable restriction or impediment
on the sale, assignment and transfer thereof ceases to exist (such occurrence, the “ Consent Receipt ”), neither such
Restricted Asset nor such Restricted Split Interest shall constitute a Purchased Asset; provided that at no time on or after the
Closing shall any Restricted Assets or Restricted Split Interest for which the Consent Receipt has not occurred constitute Excluded Assets
nor shall any Liability arising out of, or related to, such Restricted Assets or Restricted Split Interest constitute an Excluded Liability
solely by virtue of being a Restricted Asset or Restricted Split Interest, in each case, for purposes of the Seller’s indemnification
obligations under Section 9.1(a)(i)(6). Upon the Consent Receipt, the Seller shall sell, assign, and transfer the relevant
Purchased Asset to which such Consent Receipt relates to Purchaser for no additional consideration.

22

(b) From
the Agreement Date until the earlier of (x) the date this Agreement is terminated in accordance with its terms and (y) 12
months following the Closing, each of the Seller and Purchaser shall use, and shall cause their respective controlled Affiliates to use,
commercially reasonable efforts, and shall reasonably cooperate with each other, to obtain or to cause to be obtained any requisite Consent,
substitution, replacement agreement or amendment required to assign, transfer and novate to Purchaser all rights and obligations of the
Seller and its Subsidiaries with respect to the Purchased Assets and the Assumed Liabilities such that, in any case, Purchaser or a designated
Affiliate of Purchaser will have the benefit of such rights and shall be solely responsible for such Assumed Liabilities from and after
the Closing Date. Nothing in this Section 2.5 shall require Purchaser, the Seller or any of their Affiliates to pay any
amount, grant any rights, grant any guarantee or provide any other consideration to any third party or incur additional costs or expenses
in order to obtain any such Consent, except to the extent the other Party consents to make any such payments, or provide such grants
or consideration. In the event that the Seller determines to seek an assignment or novation with respect to any Assigned Contract, Purchaser
shall cooperate with, and shall cause its Affiliates to cooperate with, the Seller and its Affiliates (including, where necessary, entering
into appropriate instruments of assumption) to cause such assignment or novation to be obtained and to have the Seller and its Affiliates
(other than the Quark Companies) released from all liability to third parties with respect to such Assigned Contract to the extent consistent
with the terms of this Agreement. With respect to any Assumed Liabilities for which the Seller, or any Non-Transferred Affiliate, has
any secondary liability to third parties, Purchaser shall provide the Seller with reasonable access and information in order for the
Seller to ascertain continuing compliance by Purchaser and its Affiliates with all material contract terms and conditions applicable
thereto. This Section 2.5(b) does not relate to Shared Contracts which are addressed in Section 2.5(c).

(c) The
Seller shall use commercially reasonable efforts to separate the rights and obligations under each Shared Contract to the extent related
to the Quark Business and assign and transfer to Purchaser any transferable interest in each such Shared Contract to the extent related
to the Quark Business (a “ Split Interest ”). If an attempted assignment and transfer of a Split Interest to Purchaser,
without obtaining the Consent of the relevant counterparty to such Shared Contract (the “ Relevant Vendor ”), would
constitute a breach or other contravention of the terms of the applicable Shared Contract, or would in any material way adversely affect
the rights of the Seller or its Affiliates with respect to such Shared Contract or, upon transfer, of Purchaser or its Affiliates (including
the Quark Companies) with respect to such Split Interest, as applicable (each, a “ Restricted Split Interest ”), then
the Seller and Purchaser shall reasonably co-operate with each other and shall each use commercially reasonable efforts to either obtain
the requisite Consent from the Relevant Vendor for the assignment and transfer to Purchaser of such Restricted Split Interest prior to
the Closing, or to negotiate and enter into a new agreement with the Relevant Vendor or a replacement vendor or supplier reasonably acceptable
to Purchaser, as mutually agreed by the Seller and Purchaser, for the provision by such vendor of the same or materially similar products,
services or rights to Purchaser or its designated Affiliate following the Closing as are provided to the relevant Quark Company under
such Shared Contract as of the Agreement Date upon terms and conditions to be agreed (or otherwise upon the standard terms and conditions
offered by the relevant vendor or supplier) (a “ Replacement Contract ”). To the extent such Consent or Replacement
Contract is not obtained prior to the Closing, each of the Seller and Purchaser shall continue to reasonably cooperate with each other
and use commercially reasonable efforts to obtain such Consent or such Replacement Contract, as applicable, until the earlier of (i) the
expiration of 12 months following the Closing Date to obtain such Consents or Replacement Contract, and (ii) the termination, expiration,
lapse or non-renewal of such or expiration of such Shared Contract in accordance with its terms; provided that nothing herein shall require
the Seller or any of its Affiliates to pay any amount, grant any rights, litigate, grant any guarantee, incur any Liability or provide
any other consideration to any relevant vendor or supplier or any other party or incur out-of-pocket costs or expenses in order to obtain
any such Consent or Replacement Contract. Once Consent is obtained for the Transfer of a Restricted Split Interest, such Restricted Split
Interest shall be Transferred to Purchaser (but not before), and such Restricted Split Interest shall be deemed to be a Purchased Asset
for purposes of this Agreement.

23

(d) If
any required Consent to assign and transfer a Restricted Asset or a Restricted Split Interest is not obtained on or prior to the Closing
Date (or in the case of a Shared Contract, a Replacement Contract is not in place in lieu of the assignment and transfer of the relevant
Restricted Split Interest), each of the Seller and Purchaser hereby agree to use commercially reasonable efforts to implement such arrangements
(including subleasing, sublicensing or subcontracting) with respect to the underlying rights and obligations related thereto, to the
extent practicable and/or permitted by applicable Law, for Purchaser or one of its Affiliates to perform and discharge (and Purchaser
hereby agrees to perform and discharge) the obligations of the Seller or any applicable Subsidiary of the Seller after the Closing Date
thereunder (to the extent such obligations would otherwise constitute Assumed Liabilities), in exchange for all corresponding rights,
benefits and payments thereunder arising or made after the Closing Date being made available to Purchaser or such Affiliate, and for
Purchaser or one of its Affiliates to assume and timely discharge the obligations of the Seller and its Affiliates with respect thereto
(the “ Restricted Asset Obligations ”), until the earlier of (i) such time as such Consent to Transfer the applicable
Restricted Asset shall have been obtained (or, in the case of a Restricted Split Interest, a Replacement Contract has been put in place,
as applicable), and (ii) in the case of a Restricted Asset that is a Contract or a Restricted Split Interest, such time as such
Contract or Restricted Split Interest shall have lapsed, terminated, expired or not have been renewed in accordance with its terms. Purchaser
agrees to timely perform and fully discharge, or cause its Subsidiaries to timely perform and fully discharge, the Restricted Asset Obligations,
directly or indirectly, as applicable, and shall indemnify, defend and hold harmless the Seller and its Affiliates for any Losses resulting
from the failure of Purchaser and its Affiliates to perform and discharge such Restricted Asset Obligations; provided, however,
that in relation to a Restricted Split Interest, Purchaser shall be responsible for the Restricted Asset Obligations related to the Restricted
Split Interest only and not the remaining portion of the relevant Shared Contract. Upon Consent Receipt with respect to a particular
Restricted Asset or Restricted Split Interest after the Closing Date, the Parties agree that the obligations related to such Restricted
Asset or Restricted Split Interest will no longer be considered to be Restricted Asset Obligations at such time but will instead be deemed
to be Assumed Liabilities for all purposes of this Agreement.

(e) Notwithstanding
anything herein to the contrary, the provisions of this Section 2.5 shall not apply to any Consent required from any Governmental
Entity with respect to the consummation of the transactions contemplated hereunder, which Consents shall be governed solely by Section 4.5.

24

(f) Notwithstanding
anything in this Agreement to the contrary, the failure to obtain any Consent (other than any required Consent of a Governmental Entity)
for the sale, assignment and transfer of any Purchased Asset to Purchaser or its designated Affiliates, or the failure to transfer any
Restricted Split Interest, or the termination (or receipt of notice of termination thereunder) of any Contract that was intended to be
an Assigned Contract or any Shared Contract, or any facts, circumstances, effects or consequences resulting from any of the foregoing,
shall not, individually or in the aggregate, give rise to any liability whatsoever of the Seller or its Affiliates arising out of or
relating to such failure, or constitute a Material Adverse Effect, or a breach by the Seller of any representation, warranty or covenant
under this Agreement or any of the other Transaction Documents, or a failure of the satisfaction of any condition under this Agreement
or any of the Transaction Documents, including those in Section 3.2 and, subject to the satisfaction or waiver of the conditions
contained in Article 3, the Closing shall occur notwithstanding the foregoing without any adjustment to the Purchase Price
on account thereof.

(g) In
the event that there are any Contracts for the purchase of products or services from or by the Seller or any of its Affiliates that are
exclusively related to the Quark Business which were not included in the Purchased Assets or the Assumed Liabilities and which were not
specifically excluded from the transfers under this Agreement, but which would have been transferred to Purchaser as part of this Agreement
but for the fact that such Contract was not identified, discovered or located until after the Closing or inadvertently was not assigned
(each, a “ Later Discovered Contract ”), to the extent permitted under the terms and conditions of such Later Discovered
Contract and under applicable Laws, Purchaser and the Seller agree to cooperate and take such actions as may be necessary to cause such
Later Discovered Contract, or the applicable rights or obligations under such Later Discovered Contract, to be assigned to Purchaser
for no additional consideration and, upon such assignment, such Later Discovered Contract, or the applicable rights or obligations under
such Later Discovered Contract, shall be deemed to be an Assigned Contract hereunder. To the extent that a Later Discovered Contract
constitutes a Restricted Asset, it shall be treated in accordance with the foregoing provisions of this Section 2.5.

withheld, conditioned or delayed) to the extent that such settlement or compromise could reasonably be expected to increase the liability
for Seller for Taxes under this Agreement or decrease the Tax attributes of Seller or any of its Affiliates.

7.3 Straddle
Period. To the extent necessary to determine the allocation of Taxes in respect of a Straddle Period, Taxes of the members of the
Company Group based on or measured by income, gross or net sales, payroll, payments or receipts shall be allocated between the Pre-Closing
Tax Period and the Post-Closing Tax Period based on an interim closing of the books as of the close of business on the Closing Date and
any other Taxes shall be allocated between the Pre-Closing Tax Period and the Post-Closing Tax Period on a per diem basis. With respect
to the preparation of any income Tax Return for any Pre-Closing Tax Period or Straddle Period, the parties agree that any items of income,
gain, loss and deduction attributable to transactions undertaken by or at the direction of Purchaser or its Affiliates (including the
members of the Company Group following the Closing) outside the ordinary course of business on the Closing Date and after the time of
the Closing will not be taken into account in the Pre-Closing Tax Period.

7.4 Post-Closing
Actions. Without the prior written consent of the Seller (not to be unreasonably withheld, conditioned or delayed), Purchaser shall
not, and shall cause its Affiliates not to (i) make any Tax election with respect to any member of the Company Group for any Pre-Closing
Tax Period, (ii) take any action on the Closing Date after the Closing that is outside the Ordinary Course of Business with respect
to the member of the Company Group, (iii) amend any Tax Return of a member of the Company Group for any Pre-Closing Tax Period,
or (iv) cause a member of the Company Group to initiate or enter into any voluntary disclosure or similar program or agreement
for any Pre-Closing Tax Period. Purchaser (a) shall not make an election under sections 338 or section 336 with respect to any
of the transactions contemplated by this Agreement without the express written consent of the Seller, and (b) if requested by the
Seller, will make an election under Section 338(g) of the Code with respect to its purchase of CareDx Pty Ltd.

7.5 Cooperation
on Tax Matters. Purchaser and the Seller agree to furnish or cause to be furnished to each other, upon request, as promptly as practicable,
such information (including access to books and records) and assistance relating to Tax periods or portions of Tax periods of any member
of the Company Group ending on or before the Closing Date as is reasonably necessary for the filing of any Tax Return, for the preparation
of any audit and for the prosecution or defense of any claim, suit or proceeding relating to any proposed adjustment. Notwithstanding
anything to the contrary set forth in this Agreement, Purchaser and the Seller agree to retain or cause to be retained all books and
records relating to Tax matters for Tax periods or portions of Tax periods of any member of the Company Group ending on or before the
Closing Date until thirty (30) days after the applicable period for assessment under applicable Law (giving effect to any and all extensions
or waivers) has expired, and to abide by or cause the abidance with all record retention agreements entered into with any taxing authority.
Purchaser and the Seller shall cooperate with each other in the conduct of any audit or proceeding involving any member of the Company
Group for any Tax purposes and each shall execute and deliver such powers of attorney and other documents as are necessary to carry out
the intent of this subsection.

7.6 Transfer
Taxes. The Seller shall be responsible for the timely payment of all Transfer Taxes, if any, arising out of or in connection with
the transfers contemplated by this Agreement, other than in connection with any incremental Transfer Taxes arising out of or in connection
with the transfers contemplated by the Alternate Transferee List, for which Purchaser shall be responsible. Purchaser shall, or shall
cause the Company to, at the expense of the Seller, prepare and file all necessary documentation and Tax Returns with respect to such
Transfer Taxes. Seller shall timely reimburse Purchaser or, as applicable, the Company, for payments due under this Section 7.6 within ten (10) business days after Purchaser or, as applicable, the Company, submits written documentation establishing that it
made a payment of any such Transfer Taxes. Each of the Parties to this Agreement shall cooperate with Purchaser or the Seller, as the
case may be, and take any action reasonably requested which does not cause them to incur any unreasonable cost or inconvenience in order
to minimize such Transfer Taxes.

7.7 Withholdings.
Notwithstanding anything to the contrary contained in this Agreement, Purchaser shall have the right to withhold any portion of the Purchase
Price or of any other payment due to the Seller pursuant to this Agreement as may be required under the applicable Law, including without
limitation any Tax law, of any country, state or locality and shall timely pay over to the appropriate Governmental Entity any amounts
required to be deducted or withheld pursuant to this Agreement. Purchaser will use commercially reasonable efforts to notify Seller prior
to deducting or withholding any amounts from Seller pursuant to this agreement, and shall cooperate with the Seller in good faith to
minimize any deduction or withholding under this Agreement.

7.8 Tax
Refunds. Tax refunds that are received by Purchaser or any member of the Company Group after the Closing Date that relate to a Pre-Closing
Tax Period (including any refund to any Quark Company of any tariffs or customs duties with respect to Quark Products or Quark Software
sold during the Pre-Closing Tax Period, and any refund attributable to the overpayment of estimated U.S. state income or franchise taxes
paid by CareDx Lab Solutions, Inc.) and Taxes paid by the Seller or any member of the Company Group prior to the Closing shall
be for the account of the Seller, and Purchaser shall pay over to the Seller any such refund, less any Taxes imposed on the collection
of such Tax refund and any reasonable out-of-pocket costs incurred solely for the purpose of obtaining such refund, within 15 calendar
days after receipt thereof.

53

7.9 Purchase
Price Allocation. The Purchase Price shall be allocated among the assets of the Company (including the shares of the Company’s
Subsidiaries) and the Purchased Assets conveyed by the Seller hereunder as agreed by the Parties and in a manner consistent with Section 1060
of the Code (and any similar provision of state, local, or non-U.S. Law, as appropriate). Within 120 days following the Closing, Seller
shall prepare such an allocation in such a manner and provide such allocation to Purchaser, and such allocation shall be subject to the
review and comment of Purchaser. Seller shall consider, reasonably and in good faith, all comments of Purchaser provided within 60 days
of receipt of Seller’s allocation and the parties shall work together, reasonably and in good faith, to resolve any differences
and agree on a final allocation; provided that if no such agreement can be reached with respect to the allocation, such matter shall
be submitted by the parties to a mutually acceptable nationally recognized accounting firm, whose determination shall be limited to choosing
either the allocation proposed by Purchaser or the allocation proposed by Seller, which determination shall be final and binding on each
of Purchaser and Seller. Any fees or expenses of such accounting firm shall be borne by the Party that does not prevail. The parties
shall timely file a Form 8594 with the Internal Revenue Service in connection with such final allocation and shall otherwise report
the transactions contemplated by this Agreement in a manner consistent with such allocation.

ARTICLE 9
ADDITIONAL AGREEMENTS

9.1 Indemnification.

(a) Seller’s
Indemnification Obligation.

(i) Subject
to the other limitations in this Article 9, from and after the Closing, the Seller agrees to indemnify Purchaser and any
Affiliate of Purchaser and their respective officers, directors, members, employees, agents and representatives (collectively, the “ Purchaser
Indemnitees ”) and hold each Purchaser Indemnitee harmless from and against any Losses which any Purchaser Indemnitee actually
pays, incurs or suffers to the extent arising or resulting from:

(1) Any
Fraud on the part of the Seller;

(2) any
representation or warranty made by the Seller in or pursuant to Section 5.3 of this Agreement being untrue or incorrect
in any material respect (A) as of the Agreement Date or (B) as of the Closing Date as though such representation, warranty,
or certification were made as of the Closing Date;

(3) (x) the
Natera Litigation and (y) any material claims made by Natera after the Closing against the Purchaser or any of the Quark
Companies based on the same facts as those that are a subject matter in the Natera Litigation solely to the extent related to the conduct
of the Quark Business by the Quark Companies during the period prior to the Closing;

(4) any
Tax matter described in Schedule 9.1(a)(i)(4) of the Disclosure Schedules;

(5) any
Excluded Liability.

(ii) The
Seller will not be liable under this Section 9.1(a) unless a written Claim Notice is given by or on behalf of the
claiming Purchaser Indemnitee to the Seller on or before the relevant Seller Survival Date, it being understood that so long as such
Claim Notice is provided on or prior to the relevant Seller Survival Date, such Purchaser Indemnitee’s right to be indemnified
with respect to the matters covered in such Claim Notice shall continue and survive with respect to such matter and the provisions that
are the subject of such notice until such matters are resolved. For purposes of this Agreement, the term “ Seller Survival Date ”
shall mean (A) with respect to any claim for any Loss indemnifiable pursuant to Section 9.1(a)(i)(3), the date that

56

(iii) The
indemnification provided for in this Section 9.1(a) above is subject to each of the following further limitations:

(1) Except
with respect to liability of the Seller for Fraud committed by the Seller or the indemnification obligation of the Seller relating to
Excluded Liabilities, the Seller shall not be liable to indemnify Purchaser Indemnitees pursuant to Section 9.1(a) until
the Purchaser Indemnitees have collectively suffered aggregate Losses exceeding $250,000 (such amount of Losses, the “ Seller
Indemnification Threshold ”), at which point the Seller then shall, subject to the other limitations set forth in this Article 9,
be liable under this Section 9.1(a) for all Losses in excess of the Seller Indemnification Threshold. The Seller Indemnification
Threshold shall not apply with respect to attorney’s fees and litigation costs incurred in connection with the matters indemnifiable
pursuant to Section 9.1(a)(i)(3).

(2) The
Seller shall be liable for and shall be bound by the terms of Section 9.1(a) for an aggregate amount of indemnifiable
Losses of up to, but not more than, the amount of the Purchase Price actually received by the Seller hereunder, except that with respect
to Losses indemnifiable by the Seller pursuant to Section 9.1(a)(i)(1) or Section 9.1(a)(i)(4), the liability
of the Seller for such claims shall be uncapped.

(3) Any
Loss shall be indemnifiable pursuant to Section 9.1(a) only to the extent (i) that it is not included as a liability
in the Final Net Cash/Net Working Capital Statement or, if it is included as a liability in the Final Net Cash/Net Working Capital Statement
and to the extent it exceeds such liability, then to the extent of such Loss minus the amount of such liability reflected in the Final
Net Cash/Net Working Capital Statement, or (ii) that such Loss is not covered by or not recoverable under the RW Insurance.

Seller and their respective officers, directors, shareholders, employees, agents and representatives (each, a “ Seller Indemnitee ”)
and hold the Seller Indemnitees harmless from and against any Loss which any such Seller Indemnitee actually pays, incurs or suffers
to the extent arising or resulting from:

57

(1) any
Fraud of Purchaser;

(2) any
representations or warranties made by Purchaser in this Agreement or certificate delivered pursuant to this Agreement being untrue or
incorrect (A) as of the Agreement Date (except to the extent that such representations, warranties, and certifications speak as
of an earlier date, in which case as of such earlier date) or (B) as of the Closing Date as though such representation, warranty,
or certification were made as of the Closing Date (except to the extent that such representations, warranties, and certifications speak
as of an earlier date, in which case as of such earlier date);

Purchaser Assumed Contractual Liabilities, or

(4) the
Assumed Liabilities.

(ii) Purchaser,
or, with respect to Section 9.1(b)(i)(4), the Company, will not be liable to indemnify the Seller Indemnitees under Section 9.1(b) unless
a Claim Notice is given by or on behalf of the claiming Seller Indemnitee to Purchaser on or before the relevant Purchaser Survival Date,
it being understood that so long as such Claim Notice is provided on or prior to the relevant Purchaser Survival Date, such Seller Indemnitee’s
right to be indemnified with respect to the matters covered in such Claim Notice shall continue to survive until such matters are resolved.
For purposes of this Agreement, the term “ Purchaser Survival Date ” shall mean (A) the date that is twenty-four
(24) months after the Closing Date in the case of any claim for indemnification pursuant to Section 9.1(b)(i)(2), and (B) the
date that is thirty days following the expiration of the applicable statute of limitations for the subject matter of any claim for claims
made pursuant to Section 9.1(b)(i)(1), Section 9.1(b)(i)(3) and Section 9.1(b)(i)(4).

(iii) Except
with respect to indemnification by the Purchaser for any Fraud committed by the Purchaser or the indemnification obligation of the Company
pursuant to Section 9.1(b)(i)(3) and Section 9.1(b)(i)(4), which indemnification obligations shall not
be limited, Purchaser shall be liable to indemnify Seller Indemnitees pursuant to Section 9.1(b) for and shall be
bound by the terms of Section 9.1(b) for an aggregate amount of indemnifiable Losses of up to, but not more than,
the amount of the Purchase Price actually paid by the Purchaser hereunder.

(c) Indemnification
Procedures.

(i) Notice
of Claim. Any indemnified party making a claim for indemnification pursuant to Sections 9.1(a) or (b) (a
“ Claim ”) must give the Seller or Purchaser, as the case may be, written notice (a “ Claim Notice ”)
of any matter which such indemnified party has determined has given rise to, or could reasonably be expected to give rise to, a right
of indemnification under this Article 9, within sixty (60) days of such determination (and in any event promptly after the
indemnified party receives any written notice of any Proceeding or other claim against or involving the indemnified party by a third
party), stating the amount of the Loss, if known, and method of computation thereof, and containing a reference to the provisions of
this Agreement in respect of which such right of indemnification is claimed or arises; provided, however, that the failure
to provide such notice shall only release the applicable indemnifying party from any of its obligations under this Article 9 to the extent (if any) such indemnifying party is actually materially prejudiced by such failure.

58

(ii) Proceedings.
In the event of a Proceeding, the indemnified party shall keep the indemnifying party reasonably informed with respect to such ongoing
Proceeding, and the indemnifying party may provide the indemnified party with guidance and advice with respect to the Proceeding, which
the indemnified party shall reasonably consider to the extent such guidance and advice are reasonable and in the common interests of
the indemnified party and the indemnifying party.

(iii) Net
Recovery. The amount of any Loss for which indemnification is provided under this Section 9.1 shall be net of the amount
of such Loss (if any) actually recovered by the indemnitee under insurance policies (including, in the case of the Purchaser Indemnitees,
the RW Insurance), net of costs of collection and reasonably estimated costs of premium increases, if any, attributable to insurance
claims with respect to such Loss, and for the avoidance of doubt the indemnitee shall not be obligated to pursue litigation or take other
material steps against the relevant insurance company if the insurance company denies or limits coverage after receiving notice of a
claim (except in the case of the RW Insurance where Purchaser agrees to use reasonable best efforts and to take all actions necessary
to obtain coverage from the insurance company and enforce its rights under the RW Insurance with respect to any such Loss to the extent
such Loss is covered under the RW Insurance).

(iv) Natera
Settlement. Notwithstanding the foregoing, with respect to the Natera Litigation, the Seller shall not enter into any settlement
that imposes any payment obligation, restriction or license requirement on the Quark Business, the Quark Products or the Quark Software,
or Purchaser or its Affiliates, without Purchaser’s prior written consent (collectively, the “ Natera Litigation Matters ”).

(v) RW
Insurance. Notwithstanding anything to the contrary herein, in the event of any Losses incurred by Purchaser that are indemnifiable
by the Seller pursuant to Section 9.1(a)(i)(1) through Section 9.1(a)(i)(3), Purchaser shall first seek
recourse and obtain recourse for any such Losses to the maximum extent of the available coverage therefor under the RW Insurance before
seeking indemnification with respect thereto against the Seller. Purchaser acknowledges and agrees that other than respect to the indemnifiable
matters described in Section 9.1(a)(i)(1) through Section 9.1(a)(i)(3), recourse by the Purchaser to
the RW Insurance constitutes Purchaser’s sole and exclusive remedy for any and all Losses arising out of, resulting from, related
to or in connection with any breach by the Seller of any of its representations and warranties set forth in the Agreement.

59

(d) Claims;
Payments. The indemnifying party shall inform the party seeking indemnification not later than ten (10) days after its
receipt of a Claim Notice whether it objects to such Claims and stating in writing its grounds of objection. All indemnification payments
shall be made promptly in accordance with the Claim Notice unless the indemnifying party shall have objected to such Claim. All indemnification
payments made under this Agreement shall be treated for Tax purposes only as an adjustment to the Purchase Price.

(e) No
Knowledge Effect. Except as expressly provided in this Agreement, the right to indemnification, reimbursement or other remedy pursuant
to or based on this Section 9.1 shall not be affected by any Knowledge existing, acquired or capable of being acquired at
any time, whether before or after the execution and delivery of this Agreement or the Closing Date.

(f) Following
the Closing, with the exception of remedies based on Fraud by any Party or breach by any Party of any covenants or agreements of such
Party under this Agreement, the indemnification rights set forth in this Section 9.1 shall constitute the sole and exclusive
remedy of a Party for money damages hereunder and shall be in lieu of any other remedies for money damages that may be available to the
indemnified Persons hereunder under any other agreement or pursuant to any statutory or common law with respect to any Losses, Liabilities,
Proceedings, settlements, judgments, awards, penalties, fines, costs or expenses of any kind or nature incurred directly or indirectly
resulting from or arising out of, under or with respect to any of this Agreement, the Quark Business, the Purchased Assets, the Excluded
Assets, the Assumed Liabilities or the Excluded Liabilities (it being understood that nothing in this Section 9.1(f) or
elsewhere in this Agreement shall affect the rights of any Party to specific performance or other similar non-monetary equitable remedies
with respect to the covenants referred to in this Agreement to be performed after the Closing). Each of the Parties hereby waive any
provision of any applicable Law to the extent that it would limit or restrict the agreement contained in this Section 9.1(f).

(g) Purchaser
and the Seller agree to treat (and cause their respective Affiliates to treat) any payment received by Seller Indemnitees or the Purchaser
Indemnitees, as applicable, pursuant to this Section 9.1 as adjustments to the Purchase Price for all Tax purposes to the
maximum extent permitted by Applicable Law.

60

9.2 Minimum
Employees.

(a) Purchaser
shall, or shall cause its Affiliates, to hire and employ the Minimum Quark Employees by providing, no less than 15 days prior to the
Closing Date or any prior date required by applicable Law, an offer of employment to such Quark Employees to become effective on the
Closing Date providing for (i) annual salary or wages in amounts substantially equivalent to the annual salary or wages, as applicable,
paid to such employees by the Seller or any of its Affiliates as of immediately prior to the Closing Date, (ii) cash incentive
compensation opportunities or sales commission arrangements (but excluding any transaction-related incentives, bonus or retention payments,
including without limitation any such payments related to work performed or contributions in connection with the signing, closing or
performance of this Agreement) in amounts substantially equivalent to the cash incentive compensation opportunities or sales commission
arrangements provided to such employees by the Seller or any of its Affiliates as of immediately prior to the Closing Date, (iii) employee
benefits (including retirement benefits, health, vision and dental insurance, life and AD&D insurance, disability insurance, vacation
PTO, sick, holiday, maternity, paternity and other leave) substantially equivalent, in the aggregate, to those provided through the Seller’s
or any of its Affiliates’ employee benefits plans at the time of this Agreement, and (iv) the Post-Closing Severance Benefits,
it being understood that, with respect to the Minimum Quark Employees who are employees of a Quark Company as of immediately prior to
the Closing, such offer may be limited to terms required to be offered to such Minimum Quark Employee as a result of their employer ceasing
to be the Seller or a Non-Transferred Affiliate of the Seller.

(b) Purchaser
agrees to maintain each Minimum Quark Employee’s employment terms as contemplated above during the 12-month period following the
Closing Date or such longer period as required by any applicable local Laws (the “ Continuation Period ”), provided
however that Purchaser may terminate any benefits offered to any Minimum Quark Employees during the Continuation Period so long as Purchaser
replaces such terminated benefits with a comparable benefit.

(c) Purchaser
will reasonably consult with and provide the Seller with a reasonable opportunity to review the proposed terms and conditions of the
offers of employment to be made to the Minimum Quark Employees in advance.

(d) To
the extent that a Minimum Quark Employee is inactive as of the Closing Date due to short-term or long-term disability, workers’
compensation leave, or military leave, the offer of employment referred to in subparagraph (a) above will become effective when
such leave ends and the employee returns to work.

(e) Purchaser
or any of its Affiliates will credit each Minimum Quark Employee that remains employed with a Quark Company upon the Closing, or that
accepts an offer of employment from Purchaser or an Affiliate of Purchaser, as applicable (each a “ Continuing Employee ”)
with, and honor and pay for, the amount of accrued and unpaid hours of vacation (to the extent permitted by Law), personal hours or days
earned, sick leave and any other leave required to be credited by Law (together, the “ Transferred Leave ”) applicable
to such Continuing Employee for the period up to the Closing. The Seller will provide to Purchaser as of the Closing Date a schedule
indicating the type and number of days of Transferred Leave for each Continuing Employee. Purchaser will ensure that such Transferred
Leave is not subject to forfeiture to the same extent not subject to forfeiture under the policies of the Seller and its Affiliates governing
such Transferred Leave prior to the Closing.

61

(f) Any
employee that is a Minimum Quark Employee who is not offered continued employment with Purchaser or any of its Affiliates effective upon
the Closing, or who is terminated without cause upon the Closing or at any time during the 12 months following the Closing, shall be
entitled to severance and termination benefits (the “ Post-Closing Severance Benefits ”) having an aggregate value equal
to the higher of (i) the aggregate value of the severance and benefits described in Schedule 9.2(f) of the Disclosure
Schedule and (ii) the aggregate value of severance or additional termination payments, payments in lieu of notice or other benefits
as may be required by applicable Law, with Purchaser being solely responsible for discharging all costs and obligations related to the
Post-Closing Severance Benefits that become payable to any such Minimum Quark Employee.

(g) To
the extent permitted or required by applicable Law, Purchaser will cause each employee benefit plan of Purchaser and its Affiliates in
which any Continuing Employee participates that is a health or welfare benefit plan (collectively, “ Purchaser Benefit Plans ”)
to, if and only if and to the extent that the Purchaser employee benefit plans allows for it without amending the terms thereof, (i) waive
all limitations as to preexisting conditions, exclusions and service conditions or waiting periods or evidence of insurability requirements
with respect to participation and coverage requirements applicable to Continuing Employees, (ii) honor any payments, charges and
expenses of such Continuing Employees (and their eligible dependents) that were applied toward the deductible and out-of-pocket maximums
under the corresponding Seller benefit plan in satisfying any applicable deductibles, out-of-pocket maximums or co-payments under a corresponding
Purchaser Benefit Plan during the same plan year in which such payments, charges and expenses were made, and (iii) with respect
to any medical plan, waive any waiting period limitation or evidence of insurability requirement that would otherwise be applicable to
a Continuing Employee following the Closing Date.

(h) Purchaser
and its Affiliates will provide credit for each Continuing Employee’s length of service with Seller and its Affiliates for purposes
of eligibility, participation, vesting and benefit accrual under each plan, program, policy or arrangement of Purchaser and its Affiliates
(including severance plans and policies), except that such prior service credit will not be required to the extent that it results in
a duplication of benefits. Seller will provide to Purchaser as of the Closing Date a schedule indicating the length of service of each
Continuing Employee with Seller and its Affiliates through the Closing Date.

(i) Purchaser
shall have no obligation pursuant to this Section 9.2 with respect to Quark Employees who have been offered employment by
Purchaser or its Affiliates in accordance with the terms of this Section 9.2 but who have not accepted such offer before
the end of the day on the Closing Date.

(j) Seller
shall be solely responsible for, all restructuring, severance and termination costs (including reasonable attorneys’ fees, payroll
taxes and social security contributions owed by the employer) payable in connection with the termination of any employees or consultants
of the Quark Business not included in the Minimum Quark Employees list who are not hired or retained by the Seller or any of its Non-Transferred
Affiliates, or who are terminated by the Seller, upon the Closing (the “ Non-Transferred Employee Commitment ”).

62

(k) To
the extent that the Company will not hold sufficient Cash in the full amount of the Estimated Employees Severance Budget as of the Closing
Date, the Seller shall, on or prior to the Closing Date, make a cash payment to the Company in an amount sufficient to ensure that the
Company will hold an amount of Cash equal to the Estimated Employees Severance Budget (as defined in the Purchase Price Adjustments Schedule)
as of the Closing Date. The Seller shall cause the Company to retain such Employees Severance Cash in its operating accounts as of the
Closing. Notwithstanding Section 2.4, the Employees Severance Cash shall not be treated as an Excluded Asset.

9.3 Post-Closing

access during normal business hours, to the other Party’s employees (without unreasonable disruption of employment) and to any
material books, records, documents, files and correspondence in the possession or under the control of the other Party that the requesting
Party reasonably needs (i) to comply with reporting, disclosure, filing or other requirements imposed on the requesting Party (including

other similar privilege, and each Party may redact information regarding itself or its Subsidiaries or otherwise not relating to the
Quark Business, and, in the event such provision of information could reasonably be expected to violate any Law or agreement or waive
any attorney client or other similar privilege, the Parties shall take all reasonable measures to permit the compliance with such obligations
in a manner that avoids any such harm or consequence.

(b) Ownership
of Information. Any information owned by a Party that is provided to a requesting Party pursuant to this Section 9.3 shall be deemed to remain the property of the providing Party. Unless specifically set forth herein, nothing contained in this Agreement

set forth in this Agreement.

(e) Confidential

regarding the confidentiality of confidential and proprietary information; provided, however, that in the event that either
Party is required under this Section 9.3 to disclose any such information, such Party shall use commercially reasonable
efforts to seek to obtain such third party’s consent to the disclosure of such information and implement requisite procedures to

or its Affiliates’ insurance policies or by any of Seller’s self-insured programs, and Seller and its Affiliates may, to
be effective at the Closing, amend any insurance policies in the manner Seller deems appropriate to give effect to this Section 9.4.
From and after the Closing, Purchaser shall be responsible for securing all insurance it considers appropriate for its operation of the
Quark Business.

9.5 Privileges.
The Parties agree that their respective rights and obligations to maintain, preserve, assert, or waive any attorney-client and work product
privileges belonging to either Party with respect to the Quark Business and the other businesses of Seller (collectively, “ Privileges ”),
shall be governed by the provisions of this Section 9.5. With respect to matters relating to Seller’s businesses,
the Excluded Assets or the Excluded Liabilities, in each case regardless of whether such matters also relate to the Quark Business, the
Purchased Assets, or the Assumed Liabilities, and with respect to all Business Records, documents, communications, or other information
(collectively, “ Information ”) of Seller or any Affiliate prepared in connection with this Agreement or the other Transaction
Documents or the transactions contemplated hereby and thereby, Seller shall have sole authority to determine whether to assert or waive
any Privileges, including the right to assert any Privilege against Purchaser and its Affiliates. Purchaser and its Affiliates (including,
as of the Closing Date, the Quark Companies) shall take no action without the prior written consent of Seller that would reasonably be
expected to result in any waiver of any such Privileges of Seller in respect of the Information. After the Closing, Purchaser shall have
sole authority to determine whether to assert or waive any Privileges with respect to matters relating to the Purchased Assets, the Quark
Companies and the Assumed Liabilities (but not including the Excluded Assets, Excluded Liabilities, Information prepared in connection
with this Agreement, the other Transaction Documents or the transactions contemplated hereby and thereby or any other potential transaction
relating to the Quark Business or related sale process, or matters that relate to the businesses of Seller (other than the Quark Business)).
However, Purchaser may not assert any such Privileges of Purchaser related to pre-Closing advice or communications relating to the Quark
Business against Seller and its Affiliates; provided, however, that, to the extent any waiver (or failure to assert such Privilege) would
reasonably be expected to result in such Privilege being waived in connection with any claim by a third party in connection with the
Purchased Assets, the Company Group or the Assumed Liabilities, Seller shall, and shall cause its Subsidiaries to, use reasonable best
efforts to enter into such reasonable arrangements designed to ensure that such Privilege is not otherwise waived with respect to such
third party, including customary joint defense agreements or similar arrangements. Seller and its Affiliates shall take no action after
the Closing without the prior written consent of Purchaser that would reasonably be expected to result in any waiver of any such Privileges
of Purchaser or its Affiliates. The rights and obligations created by this Section 9.5 shall apply to all Information as
to which Seller or its Affiliates or any of the Quark Companies would be entitled to assert or has asserted a Privilege without regard
to the effect, if any, of the transactions contemplated hereby or by the other Transaction Documents (the “ Privileged Information ”).
Upon receipt by Seller or its Affiliates, or Purchaser and its Affiliates (including, as of the Closing Date, the Company Group), as
the case may be, of any subpoena, discovery or other request from any third party that actually or arguably calls for the production
or disclosure of Privileged Information of the other or if Seller or its Affiliates or Purchaser or its Affiliates (including, as of
the Closing Date, the Company Group), as the case may be, obtains knowledge that any current or former employee of Seller, its Affiliates
or the Company Group or Purchaser or its Affiliates (including, as of the Closing Date, the Company Group), has received any subpoena,
discovery or other request from any third party that actually or arguably calls for the production or disclosure of Privileged Information
of the other Party, such Party shall promptly notify the other of the existence of the request and shall provide the other a reasonable
opportunity to review the Information and to assert any rights it may have under this Section 9.5 or otherwise to prevent
the production or disclosure of Privileged Information. Seller’s transfer of any Information to Purchaser in accordance with this
Agreement and Seller’s agreement to permit Purchaser to obtain Information existing prior to the Closing are made in reliance on
the Parties’ respective agreements, as set forth in this Section 9.5, to maintain the confidentiality of such Information
and to take the steps provided herein for the preservation of all Privileges that may belong to or be asserted by Seller or Purchaser,
as the case may be. The access to other Information being granted pursuant to Section 9.4, Section 9.12, Section 9.13 and Section 10.11, and the disclosure to Purchaser and Seller of Privileged Information relating to the Quark Business or
the other businesses of Seller pursuant to this Agreement in connection with the transactions contemplated hereby or any other Transaction
Document shall not be asserted by Seller or Purchaser to constitute, or otherwise be deemed, a waiver of any Privilege that has been
or may be asserted under this Section 9.5 or otherwise.

65

9.6 Indemnification
of Directors and Officers.

(a) If
the Closing occurs, Purchaser shall and shall cause the Quark Companies to take any necessary actions to provide that all rights to indemnification
and all limitations on liability relating to the Quark Companies existing in favor of the Business Indemnitees as provided in the D&O
Indemnity Arrangements shall survive the consummation of the transactions contemplated hereby and continue in full force and effect and
shall be honored by the Quark Companies after the Closing. As used herein, (x) the “ Business Indemnitees ” means

Companies (or the predecessors of the Quark Companies) relating to service in such capacities prior to the Closing and (y) the
“ D&O Indemnity Arrangements ” means (i) the organizational or charter documents of each of the Quark Companies

(b) In
the event that the any Quark Company or Purchaser or any of their respective successors or assigns (i) consolidates with or merges
into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers
or conveys all or a majority of its properties and assets to any Person, then, and in each such case, proper provision shall be made
so that the successors and assigns of such Quark Company or Purchaser, as the case may be, shall succeed to the obligations set forth
in this Section 9.6.

(c) Purchaser
shall procure that, at the next annual general meeting of the Company following the Closing, the directors and managing directors of
the Company resigning from such positions in connection with the Closing, to the extent legally permissible, shall be granted discharge
from any Liability to the Company with respect to their service as members of the board of directors or as managing directors of the
Company; provided, however, that no such discharge shall be granted if it is contrary to the recommendation of the auditor
of the Company.

(d) The
obligations of Purchaser and the Quark Companies under this Section 9.6 shall not be terminated or modified in such a manner
as to adversely affect any indemnitee to whom this Section 9.6 applies without the express written consent of such affected
indemnitee (it being expressly agreed that the Business Indemnitees to whom this Section 9.6 applies shall be third party
beneficiaries of and entitled to directly enforce the provisions of this Section 9.6).

9.7 Further
Assurances.

(a) In
addition to the actions specifically provided for elsewhere in this Agreement, each of the Parties will cooperate with each other and
use its commercially reasonable efforts, prior to, at and after the Closing Date, to take, or cause to be taken, all actions, and to
do, or cause to be done, all things reasonably necessary or appropriate on its part to consummate and make effective, in the most expeditious
manner practicable, the Transactions, including the execution and delivery of such other instruments, certificates, agreements and other
documents and the performance of such other actions as may be necessary or reasonably desirable to consummate and implement expeditiously
the Transactions; provided that all such actions are in accordance with applicable Law. Notwithstanding the foregoing, from time
to time, whether at or after the Closing, Seller and its Affiliates (as appropriate) will execute and deliver such further instruments,
certificates, agreements and other documents and perform such other actions, at Purchaser’s sole expense and subject to Section 2.5,
as Purchaser may reasonably require to more effectively Transfer to Purchaser any of the Purchased Assets and Purchaser will execute
and deliver such instruments, certificates, agreements and other documents and perform such other actions, at Seller’s sole expense,
as Seller or its Affiliates may reasonably require to more effectively transfer the Assumed Liabilities to Purchaser.

(b) Delivery
of Business Records and Data Migration. The Parties shall develop and implement a plan for the migration and transfer of the Business
Records held by Seller and its Affiliates (other than the Company Group) as of the Closing to Purchaser or the Company Group in connection
with the Closing. Notwithstanding anything herein to the contrary, it is understood and agreed that Seller shall only be obligated to
use reasonable efforts to locate and deliver the Business Records to the Company Group by the Closing and shall, following the Closing,
deliver any such Business Records to the Company Group that, within one year after the Closing, are identified by either the Seller or
Purchaser as still being in the Seller’s possession following the Closing (with such identification to have sufficient specificity
as to location of the relevant item so as to enable the Seller to readily find, obtain and transfer same). Except as expressly provided
in this paragraph, the Seller shall have no liability whatsoever under this Agreement or otherwise for any failure to transfer or deliver
the Business Records to Purchaser or the Company Group either at or following the Closing.

9.8 Shared
Services. Except as expressly provided for in the Transition
Services Agreement, Purchaser acknowledges and agrees that, effective as of the Closing Date, (a) all Shared Services provided

of the Quark Business or the Company Group under such Intercompany Agreements, will be terminated, discharged, cancelled or extinguished

any provision thereof that purports to survive termination) shall be of any further force or effect after the Closing.

(b) The
provisions of Section 9.9(a) shall not apply to this Agreement, the other Transaction Documents and each other agreement,
arrangement, commitment or understanding expressly contemplated by this Agreement or any other Transaction Document to be entered into
or continued after the Closing (including Transaction Documents to be effective upon the Closing).

to conduct, direct, control and be responsible for the defense, settlement and/or other resolution of such Natera Litigation Matter following
the Closing, and in such regard, shall have the right to control and direct in Seller’s sole discretion any and all investigation,
preparation, response, defense, resolution, remediation and any other action or non-action in connection therewith. Purchaser shall reasonably
co-operate with, and provide any assistance reasonably requested by, Seller and its Affiliates, including access to personnel and facilities
and access to and copies of documentation, records and information (including for purposes of deposition and trial testimony and preparation),

of Purchaser. Purchaser shall not, and shall cause its Affiliates not to, (a) take any action that would adversely affect, interfere
with or limit the ability of Seller to defend or resolve a Natera Litigation Matter in any respect, and (b) file any papers, or

of Continuing Employees. For a period of 24 months following the Closing Date, the Seller shall not, and shall cause its Affiliates
not to, directly or indirectly, solicit for employment, or engagement as an independent contractor, any Continuing Employee; provided,

Affiliates from soliciting or hiring any Continuing Employee who independently contacts the Seller or any of its Affiliates without any

rights hereunder, to seek recourse against the Seller hereunder for any matter.

with applicable Law or the rules and regulations of any national securities exchange, (b) the Parties may issue any press
release or make a public announcement (including to analysts or investors) to the extent that such release or announcement only contains
information previously publicly disclosed in accordance with this Section 9.14 or is otherwise consistent in all material

9.16 Disputes;
Arbitration Procedure.

(a) Each
of the Parties to this Agreement agrees that it will attempt to settle any dispute, claim or controversy arising out of this Agreement
through good faith negotiations.

(b) Any
dispute, claim or controversy that cannot be resolved by the Parties through good faith negotiations within thirty (30) Business Days
of the notification to the other Party of the commencement of the dispute resolution procedures of this Section 9.16 will
then, upon the written request of any Party to this Agreement, be resolved by binding arbitration conducted in English in Manhattan,
New York, NY, United States of America, in accordance with the then effective Rules of Arbitration of the International Chamber
of Commerce by a panel of three arbitrators. Such arbitrators shall be mutually agreeable to the Parties. If the Parties cannot mutually
agree upon the selection of the arbitrators, the arbitrators shall be selected in accordance with the then effective Rules of Arbitration
of the International Chamber of Commerce. Notwithstanding the foregoing, if the aggregate amount in dispute (inclusive of claims, counterclaims
and set-off defenses) does not exceed $5,000,000, the dispute shall be heard by a sole arbitrator selected in accordance with the then
effective Rules of Arbitration of the International Chamber of Commerce, unless the parties agree otherwise in writing. All arbitrators
shall be fluent in English and experienced in the negotiation and interpretation of complex cross-border share purchase agreements governed
by New York law. To the extent not governed by such rules, such arbitrators shall be directed by the Parties to set a schedule for determination
of such dispute, claim or controversy that is reasonable under the circumstances. Such arbitrators shall be directed by the Parties to
determine the dispute in accordance with this Agreement. The International Chamber of Commerce Expedited Procedure Provisions shall not
apply. The International Chamber of Commerce Emergency Arbitrator Provisions shall apply. The arbitration tribunal shall have the power
to grant any interim, conservatory or emergency measures it deems appropriate, including injunctive relief and orders for the preservation
of evidence or assets. Application to any court for such measures shall not be deemed incompatible with or a waiver of these arbitration
provisions. The Parties, their Representatives and the tribunal shall maintain the confidentiality of the arbitration proceedings, all
materials submitted or exchanged in connection with the arbitration, and any award, except to the extent disclosure is required by applicable
Law or for the purposes of enforcement of an award. The award of the tribunal shall be final and binding on the parties. Judgment upon
the award may be entered by any court of competent jurisdiction. The parties waive, to the fullest extent permitted by Applicable Law,
any right to appeal or to seek review of the award by any court or tribunal.

69

(c) Nothing
contained in this Section 9.16 shall prevent any Party to this Agreement from resorting to judicial process if injunctive
or other equitable relief from a court is necessary to prevent injury to such Party or its Affiliates and if such Party demonstrates
that the International Chamber of Commerce Emergency Arbitrator Provisions are unfit to prevent such injury. The use of arbitration procedures
will not be construed under the doctrine of laches, waiver or estoppel to affect adversely the rights of any Party to this Agreement
to assert any claim or defense other than as expressly set forth in this Agreement; the prevailing Party in the final, non-appealable
determination of any dispute, claim or controversy brought in arbitration, court or other judicial process in accordance with this Agreement
shall be reimbursed fully and promptly by the non-prevailing Party for attorneys fees and costs, arbitration fees, court costs and other
reasonable costs and expenses incurred by such prevailing Party in connection with the resolution of such dispute, claim or controversy.

rights set forth in the Distribution Agreement shall not be deemed restricted in any respect by the Non-Compete, (b) Seller’s
and its Affiliates’ development, production, marketing, sale, provision or other commercialization of any products or services
that are not a HLA Kit or PTS Kit, including without limitation all laboratory testing services, shall not be restricted in any respect
by the Non-Compete; (c) the Non-Compete shall not apply to any products or services of any entity or business acquired by Seller
or any of its Affiliates on or after the Closing Date, provided that if Seller acquires an entity or business that is commercializing
a HLA Kit or PTS Kit, then promptly following the consummation of such acquisition Seller and Purchaser shall negotiate in good faith
and enter into an exclusive distribution agreement where the Purchaser or its Affiliate shall be appointed as the exclusive distributor
of such acquired HLA Kit and/or PTS Kit in all countries and territories outside of Canada, U.S. and Mexico, and (d) the Non-Compete
shall not apply to any entity or person that acquires Seller or any of Seller’s Affiliates or to any Affiliates of such acquiring
person (other than Seller and Seller’s controlled Affiliates upon consummation of such acquisition).  As used herein, “ HLA
Kit ” means an in vitro diagnostic or RUO kit or kit-associated software consisting of a pre-packaged set of reagents
or code to allow a user to conduct genotyping using DNA, RNA or other genomic data for purposes of typing of Human Leukocyte Antigens,
and for clarity the kit may be NGS Amplicon based, Hybrid capture based, whole genome cfDNA sequencing based, SNP based and Long read

is unenforceable, invalid, contrary to Law or inequitable for any reason, nor to assert that any remedy of monetary damages would provide
an adequate remedy. Each of the parties hereto acknowledges and agrees that the right of specific enforcement is an integral part of
the Transactions and without such right, none of the parties hereto would have entered into this Agreement. If, prior to the Drop Dead
Date, any party hereto brings any Proceeding, in each case, in accordance with this Agreement, to enforce specifically the performance
of the terms and provisions hereof by any other party hereto, the Drop Dead Date shall automatically be extended by (i) the amount
of time during which such Proceeding is pending plus 10 Business Days, or (ii) such time period established by the court presiding
over such Proceeding, as the case may be.

the starting date. Unless indicated otherwise, all mathematical calculations contemplated by this Agreement shall be rounded to the tenth
decimal place, except in respect of payments, which shall be rounded down to the nearest whole United States cent. All references to

which are not otherwise defined in this Agreement have the meanings given to them under GAAP; provided, that to the extent that the definition
of an accounting term defined in this Agreement is inconsistent with the meaning of such term under GAAP, the definition set forth in

modifications or supplements hereto. Each of the representations and warranties shall have independent significance. If any Party has
breached any representation, warranty, covenant or agreement contained in this Agreement in any respect, the fact that there exists another
representation, warranty, covenant or agreement relating to the same subject matter (regardless of the relative levels of specificity)
which such Party has not breached shall not detract from or mitigate the fact that such Party is in breach of the first representation,
warranty, covenant or agreement. The principles of interpretation set forth in this Section 10.12 shall apply equally to
all Transaction Documents, unless a Transaction Document provides otherwise by its terms.

74

Performance. The parties hereto acknowledge and agree that irreparable damage would occur in the event that any of the provisions

Eurobio hereby appoints CareDx as its perpetual, exclusive distributor of the products described in Exhibit A (the “ Products ”)
in the United States (and its territories and possessions), Canada and Mexico (collectively, the “ Territory ”). CareDx
hereby accepts such appointment. In addition, Eurobio hereby grants to CareDx an exclusive, perpetual license to sell, offer for sale
and import the Products in the Territory. In the case Eurobio sells, transfers or assigns its rights in and to any of the Products (including
in the case of an acquisition of Eurobio as a company), the foregoing appointment and license grant shall run with the Products and Eurobio
shall ensure that the acquirer agrees to honor this appointment and license grant; provided, that, in the event of any sale, transfer
or assignment, the scope of the licenses and distribution rights under this Agreement shall be limited to those Products of Eurobio and
its Affiliates that are existing immediately prior to the consummation of such sale, transfer or assignment and shall not extend to the
other products and services of the acquiring entity.

1.2 Exclusivity.
For the purposes of Section 1.1 above, the term “ exclusive ” means that (a) Eurobio undertakes to not,
directly or indirectly, grant, or consent to grant, any rights to make, use, sell, offer for sale or import the Products in the Territory,
(b) Eurobio will not market, promote, sell or offer for sale the Product to any third party within the Territory, or located outside

particular, Eurobio will neither solicit nor have solicited customers for the Products in the Territory, conduct marketing activity in
the Territory for the Products nor allow any third party to do so. As used herein “ Affiliates ” means, with respect
to an entity, any other entity that directly or indirectly controls, is controlled by, or is under common control with, such entity;
where an entity shall be regarded as in control of another entity if it owns, or directly or indirectly controls, at least fifty percent

of the management and policies of the other entity by any means whatsoever.

1.3 Limited
Exceptions to Exclusivity.

(a) Notwithstanding
the exclusivity under Section 1.1 above, Eurobio or any of its Affiliates may continue to sell to Eurobio Existing Customers (as
defined below) Products that Eurobio had previously sold to such Eurobio Existing Customers prior to the Effective Date; provided that
for the avoidance of doubt, Eurobio and its Affiliates shall not have the right to sell the CareDx AlloSeq HCT or AlloSeq cfDNA products
to any customer located in the Territory other than to the CareDx Existing Customers as provided for in Section 1.3(b) below.

(b) Eurobio
or any of its Affiliates will have the exclusive right, in the Territory, to sell the CareDx AlloSeq HCT chimerism and AlloSeq cfDNA

to those academic and research institutions listed on Exhibit D (the “ Research Institutions ”) for the conduct
of research programs. Some of the Research Institutions are located outside of the Territory. Notwithstanding the foregoing in Sections 1.1
- 1.3, CareDx shall have the right to continue to provide the Legacy Products to the Research Institutions to continue to conduct such
research programs, and the pricing for such Legacy Products shall be Eurobio’s fully burdened cost to manufacture the Products,
with no mark up (i.e. the ‘at cost’ pricing). CareDx shall only sell to the Research Institutions for purposes of conduct
such research programs, and shall contractually prohibit use by Research Institutions for other purposes, but CareDx shall not be liable
if the Research Institutions use the Products outside of such research programs. CareDx will provide Eurobio with access to all data
and research results related to all Legacy Products, to the extent the Research Institutions have provided such data and research to
CareDx.

anti-corruption, ethics and compliance. To the extent that they may be applicable, CareDx agrees to comply with, and to cause its representatives
to comply with, all applicable terms and conditions of the Illumina Agreement as if CareDx were a direct party thereto, to the extent
applicable to CareDx’s performance hereunder. In the event of any conflict, inconsistency or gap between the terms of this Agreement
and the Illumina Agreement, the terms that are more protective of the rights or interests of Illumina shall govern and control with respect
to the applicable subject matter.

| | 2. | COVENANTS AND WARRANTIES. |

2.1 Registrations.
In the case any governmental registrations, licenses, permits or approvals (collectively, “ Registrations ”) are required
for the sale of the Products in the Territory, then Eurobio shall reasonably cooperate with CareDx in connection with obtaining the Registrations
and vice versa. At the request of Eurobio, CareDx shall register the Products or any component of any Product in the Territory in the
name of Eurobio. To the extent of any such request, if CareDx is prohibited by applicable law from registering Products in the name of
Eurobio and is required to identify itself to regulatory agencies as a distributor of Products, it may do so, identifying Product registered,
but it may not identify itself as the sponsor or manufacturer of the Product. Costs of registration shall be borne by CareDx, which shall
include registration renewal, and any other associated costs. In the event applicable law requires that Product registration be in the
name of CareDx, CareDx hereby agrees to transfer the Product Registration to any other person or company named by Eurobio or, cancel
the Product Registration when the transfer is not allowed by law, as may be requested by Eurobio at any time in its sole discretion.
CareDx shall maintain all appropriate administrative licenses and approvals to conduct its distribution activity in each country of the
Territory.

2.2 Compliance
with Laws. Each party shall comply with all governmental laws, regulations, and orders that may be applicable to its conduct under

2.3 Product
Recalls. CareDx shall immediately inform Eurobio in writing in the event of any customer complaints with respect to the Products.
With respect to those Products that CareDx has sold to a customer, CareDx shall promptly implement any product recall issued by Eurobio,
at Eurobio’s expense. CareDx shall maintain an accurate and up-to date product and customer database which shall be sufficient
to enable CareDx, if Eurobio so instructs, promptly to recall all units of any specific lot number of any Products.

Returns. CareDx shall ensure that, while the Product is in CareDx possession, storage and transport conditions comply with requirements
provided by Eurobio. If a Product fails to conform to the Product Warranty, CareDx may return such nonconforming Product to Eurobio,

be at no additional cost to CareDx if CareDx had previously paid Eurobio for the returned Product. The foregoing is the exclusive remedy

its supply of Products until the delay in payments is cured in fully by CareDx.

4.3 Taxes.
With respect to those Products that CareDx will be selling to its customers, CareDx shall pay all sales, use and transfer taxes and other

| | a. | License for ALLOSEQ. Subject
to the terms and conditions contained in this Agreement, LICENSOR hereby grants to
LICENSEE during the Term a, sublicenseable through multiple tiers (including, without limitation,
manufacturing and distribution) without Licensor consent (subject to Section 13 below),
non-assignable and non-transferable (except as set forth Section 14), fully paid-up,
royalty-free, license to use the Trademarks other than the CAREDX Mark in connection
with the import, export, manufacture, distribution, marketing, and sale of Licensed
Product within the Territory. All other rights in and to the Trademark are
explicitly reserved and retained by LICENSOR. LICENSEE shall not have the right to sublicense
any of the rights granted to it under this Agreement, except to Approved
Sublicensees in accordance with Section 13 below.  Notwithstanding
any other provision of this Agreement, during the Term, the LICENSOR shall not appoint
other licensees to use the Trademarks (other than CAREDX Mark) for the marketing and
sale of Licensed Products in the Territory. Except incidental to LICENSOR’s distribution
of products pursuant to the Transaction Documents, LICENSOR has agreed to cease use of the
ALLOSEQ trademark in Class 44 in connection with the Purchase Agreement transactions
and will in good faith cease such use of such trademark within a reasonable time following
execution of this Agreement not to exceed six (6) months. |

| | b. | License for CAREDX. |

| | i. | License. Subject to the terms and
conditions contained in this Agreement, beginning on the Effective Date and, for purposes
of corporate names, solely during the period set forth in Section 2(b)(v), and
for all other purposes permitted hereunder, solely during the period set forth in Section 2(b)(iii),
LICENSOR hereby grants to LICENSEE a non-exclusive, non-transferable, non-sublicensable,
fully paid-up, royalty-free, limited right and license to use the CAREDX trade name and trademark
“collectively, CAREDX Mark ” on Product Packaging and as the CAREDX Mark
may exist in any application, product registrations, product certifications relating to the
Quark Products or otherwise relating to the Quark Business, in each case with a Governmental
Entity as of the Closing, subject to the terms of this Agreement and solely in Territory,
in each case in a manner consistent with the operation of the Quark Business for the six
(6) month period immediately prior to the Effective Date or as otherwise approved in
writing by LICENSOR (the “ CAREDX License ”). |

| | ii. | Re-branding.  The CAREDX
License is granted solely for transitional purposes, and Licensee shall use commercially
reasonable efforts to cease its use of the CAREDX Mark as quickly as practicable after the
Effective Date, including by seeking labeling approval from any relevant Governmental Entity
to change the Product Packaging so that such Product Packaging no longer displays any CAREDX
Mark, by completing the transfer of the regulatory approvals and replacing the CAREDX Mark
with Licensee’s name or house mark, and by affecting corporate name change in accordance
with Section 2(b)(v). |

| | iii. | Term.  Unless terminated
earlier under Section 12 (Term and Termination), the CAREDX License will
terminate, on a Quark Product-by-Quark Product and (to the extent applicable) country-by-country
basis, after the receipt by Licensee of labeling approval from the relevant Governmental
Entity for any such Quark Product to change the Product Packaging so that such Product Packaging
no longer displays any CAREDX Mark, consistent with the timelines specified in regulations
or guidance from such Governmental Entity on implementation of labeling changes. Notwithstanding
the foregoing, the CAREDX License shall expire one (1) year after the Effective Date; provided,
however, that upon the Parties’ mutual agreement, the term of the CAREDX License can
be extended for one (1) additional year (beyond the one (1) year period immediately
following the Effective Date), not to be unreasonably disapproved by LICENSOR if LICENSEE
has expeditiously made all necessary filings and requests and taken all necessary actions
necessary actions to allow for the discontinuation of the CAREDX Mark and the continued use
by LICENSEE thereof is nevertheless necessary for the continuation of the Quark Business,
as conducted in a manner consistent with the operation of the Quark Business for the six
(6) month period immediately prior to the Effective Date, due to delays outside of
the control of LICENSEE, any Affiliate, sublicensee and Manufacturer, solely for uses affected
by such delay; and further provided that any such extension shall not apply to uses
of the CAREDX Mark in connection with packaging or associated product inserts and materials
unless required by applicable Law. |

2

| | iv. | Notice Obligations of Licensee. 
Licensee shall provide written notice to Licensor promptly upon Licensee’s receipt
of any labeling approval from the relevant Governmental Entity with respect to any Product
to change the Product Packaging so that such Product Packaging no longer displays any CAREDX
Mark. |

| | v. | Corporate Name Change. Within ten (10) Business Days
following the Closing and in accordance with applicable Law, Licensee shall file to cause
the corporate names of each of the Quark Companies to be changed to names that do not include

thereafter: (i) conduct advertising of Licensed Products targeted to any market outside of the Territory; (ii) seek orders

Trademark that are false, misleading, deceptive, or unsubstantiated; (iv) violate any laws, codes, or industry standards on advertising
and promotion, including without limitation, with respect to any comparative, off-label, or DTC communications; (v) registration
or use any marks, domains, or social handles that are confusingly similar to the Trademark; (vi) advertise, market, or promote
the Licensed Products in a way that reduces or diminishes the reputation, image, and prestige of the Trademark or of products sold under
or by reference to the Trademark; (vii) use the Trademark in any manner or take any action that could lead to dilution, confusion,
tarnishment, or third-party disputes, or could bring into disrepute the reputation of or goodwill associated with the Trademark, or which
will invalidate or jeopardize any registration of the Trademark; (viii) sell, market, distribute, or permit any third party to
sell, market or distribute, any Licensed Products that are damaged or defective; (ix) do any action or thing which shall in any
way impair LICENSOR's rights in and to the Trademark; (x) use the Trademark (or any mark confusingly similar thereto), individually
or in combination, as part of a corporate or trade name, in combination with any other trademark, word, symbol, letter or design, or
in connection with any product other than the Licensed Products; (xi) adopt, or file any application or obtain registration
of any trademark, trade dress, trade name, design, logo, symbol or any domain name containing the Trademark (or any mark confusingly

a permitted sublicensee in accordance with the terms of this Agreement.

3

5. Quality.

(a) Specifications,
Standards and Laws. LICENSEE acknowledges and is familiar with the high standards, quality, style, and image of LICENSOR, and LICENSEE
at all times shall conduct its business and use the Trademark and sell, distribute, market and exploit Licensed Products only in a manner
consistent with these standards, quality, style, and image. LICENSEE shall comply, in all material respects, with the specifications
and standards for the Licensed Products contained in the Specifications; provided that upon LICENSEE’s written notice to LICENSOR
that it wishes to modify or update the Licensed Products, the parties shall collaborate in good faith to update the applicable Specification
to reflect such changes in accordance with applicable laws and any other term of this Agreement, provided that any updated Licensed Products
shall be at least functionally equivalent to the prior version for LICENSEE’S intended use. In exercising its rights and performance
of its obligations under this Agreement, LICENSEE shall comply, and ensure that Manufacturers and sublicensees will comply, with all
applicable laws, regulations and ordinances, and industry standards, including S/H/E, and shall not act, ensure that Manufacturers and
sublicensees shall not act, in a manner that would reflect adversely upon the good name and reputation of LICENSOR or any of its programs,
products, properties or the Trademark. “ Safety, Health, Environment (S/H/E) ” means industry standards and other
standards promulgated or regulated by the US Occupational Safety and Health Administration, the US Environmental Protection Agency, state
or local agencies and, if applicable, other federal, state or local agencies charged with protecting safety, health, and environment,
and foreign equivalents, which in each case relate to employee safety, employee health and the natural or human environment.

(b) Quality
Standards. LICENSEE acknowledges that the quality of Licensed Products must be the highest in order to preserve
and maintain LICENSOR's reputation and the goodwill inherent in the Trademark, and agrees that failure to adhere to LICENSOR's
quality standards as set forth on Exhibit C hereto (“ Standards ”) will impair the value and
goodwill associated with the Trademark. LICENSEE therefore agrees that prior to the first sale of any Licensed Product bearing
any new or modified Trademarks, or manufactured using any process or facility other than those used immediately prior to the Closing,
and thereafter from time to time following LICENSOR’s reasonable written request, but in no event, without good reason, in excess
of once every twelve (12) months, it shall, at its expense, submit three (3) representative production samples of the Licensed
Product, in accordance with Specifications, all documentation describing use and application of such Licensed Product, to LICENSOR for
written approval. LICENSOR shall provide written approval or disapproval of any Licensed Products within five (5) business
days after receipt thereof, with such approval not to be unreasonably withheld. LICENSOR’s failure to approve or disapprove within
such period shall be deemed approval. LICENSOR shall have the right, in its reasonable discretion, to approve or disapprove any Licensed Products. Once
LICENSOR's final review and approval have been obtained, LICENSEE agrees that it shall not deviate from the approved samples, Standards
and Specifications without LICENSOR’s written approval. If LICENSOR determines that the Licensed Product does
not conform to the approved samples, Standards and Specifications, LICENSEE shall immediately stop the manufacture, distribution
and sale of the nonconforming Licensed Product and conform Licensed Products per LICENSOR’s reasonable request.

(c) Manufacturing
and Right to Inspect.

(i) LICENSEE
shall ensure that the production and/or manufacture of Licensed Products and/or Advertising Materials, whether by LICENSEE,
sublicensee or by third party manufacturers or suppliers selected by LICENSEE with LICENSOR’s approval (individually, a “ Manufacturer ”
and collectively, the “ Manufacturers ”), complies with the requirements of this Agreement, including those that are
set forth in this Section. LICENSEE shall ensure such compliance by Manufacturers before they contribute to production of Licensed
Products and at all times during such production. LICENSEE shall supply LICENSOR with the addresses of its manufacturing
facilities for the Licensed Products, as well as those of its sublicensees, if any, before any such facilities contribute to production
of Licensed Products. If LICENSEE becomes aware that any Manufacturer or sublicensee has used or is using Trademark for
any unauthorized purpose or in violation of this Agreement, LICENSEE shall immediately notify LICENSOR and, if so instructed by LICENSOR,
shall cause such Manufacturer or sublicensee, as applicable, to cease such use immediately.

(d) Product
Safety.

(i)          Each
party shall promptly notify the other when and if either has reason to believe that any Licensed Product poses or may pose
a health or safety risk, or does not or may not comply with any laws or regulations. In addition, LICENSEE shall promptly notify LICENSOR
of any claims, lawsuits, reports or allegations related to the Licensed Products which could give rise to a reporting obligation
under federal and/or state laws. LICENSEE shall also give LICENSOR prompt notice of all product liability claims involving any Licensed
Product. LICENSEE (A) shall promptly provide LICENSOR with details of the events that gave or are giving rise to the consideration
of a possible recall, (B) shall keep LICENSOR promptly advised of decisions concerning the recall, and (C) shall show LICENSOR
any draft announcements concerning the affected Licensed Product before making such announcement, and give LICENSOR the opportunity
to collaborate with LICENSEE on them. LICENSEE shall reimburse LICENSOR for its costs for any recall.

4

6. Advertising
Materials.

(a) Approval
of Advertising Materials. LICENSEE shall not use any Advertising Materials for which LICENSOR has not approved the Trademark
Format. Advertising Material currently marked with any Trademarks, as used immediately prior to the Closing, are hereby deemed approved
by LICENSOR. With respect to new Advertising Materials from and after the Closing, LICENSEE shall electronically submit one (1) draft
copy or otherwise send three (3) draft copies of any new Trademark Format for any such Advertising Materials to LICENSOR
for its review and written approval before printing, producing or using such Advertising Materials. For clarity, the advertising
copy for Advertising Materials of LICENSEE shall not be subject to review and approval of LICENSOR hereunder, only usage of Trademarks
in connection therewith, and only to the extent that such usage is new (e.g., differs from the Trademark Format).

(b) Time
for Approval. LICENSOR shall use reasonable efforts to provide written approval or disapproval of any Advertising Materials within
five (5) business days after receipt thereof. LICENSOR’s failure to approve or disapprove within such period shall be deemed
disapproval, unless LICENSOR subsequently notifies LICENSEE of its written approval. LICENSOR shall not unreasonably withhold approval
of any Advertising Materials.

(c) Celebrity
Endorsement. LICENSEE shall not use a personality or celebrity to endorse or promote any Licensed Products or any product or service
that bears or makes any use of or reference to the Trademark, or to use Advertising Materials, without LICENSOR’s prior written
approval.

7. Protection
of the Trademark.

(a) Registrations. Upon
LICENSEE’S request, and at LICENSEE’S expense, LICENSOR will register the Trademark in additional jurisdictions during the
Term. LICENSOR shall have the right, in its sole discretion, to file trademark, trade dress, copyright, logos, graphical designs, or
other applications in the Territory or elsewhere, relating to the use or proposed use by LICENSEE of the Trademark and
to record this Agreement. Such filings shall be made in the name of LICENSOR or in the name of any third party selected by LICENSOR.
LICENSEE shall assist LICENSOR at LICENSOR’s expense, to the extent necessary in LICENSOR’s opinion, in procuring, protecting
and defending any of LICENSOR’s rights in the Trademark, in the filing and prosecution of any trademark application, copyright
application or other applications for the Trademark, the recording or canceling of this Agreement, and the publication of
any notices or the doing of any other act or acts with respect to the Trademark, including the prevention of the use thereof by
an unauthorized person, firm or corporation, that in the judgment of LICENSOR may be necessary or desirable. For these purposes, LICENSEE
shall supply LICENSOR, free of cost to LICENSOR, such samples, containers, labels and similar materials as may reasonably be required
in connection with any such actions. LICENSOR shall, at LICENSEE’s expense, maintain all registrations set forth on Exhibit A
during the Term.

(b) Assignment
by LICENSEE. LICENSEE acknowledges that (a) LICENSOR is the owner of the Licensed Mark throughout the world and all goodwill
related thereto, and (b) all use of the Trademark by LICENSEE or sublicensees under this Agreement and any goodwill accruing from
such use will inure solely to LICENSOR’s benefit. To the extent LICENSEE acquires any rights to any of the Trademark, LICENSEE
hereby assigns and transfers to LICENSOR all such rights, together with the goodwill of the business in connection therewith, and agrees
to execute any documentation relating to such assignment. LICENSEE hereby further assigns and transfers to LICENSOR its entire worldwide
right, title, and interest in and to all trademarks created using all or any portion of the Trademark or that are confusingly
similar to the Trademark; except to the extent of any co-branding, in which case LICENSEE shall retain ownership of its proprietary marks
included in such co-branding.

(c) Trademark
Notice. LICENSEE shall affix or cause its authorized manufacturing sources to affix to the packaging for the Licensed
Products and Advertising Materials the following notice (and such other notices as may be reasonably requested from
time to time by LICENSOR), as applicable; (i) “[Trademark®] is a registered trademark of CareDx, Inc. used under
license”; or (ii) “[Trademark] is a trademark of CareDx, Inc. used under license.”

5

(d)            Notwithstanding
anything to the contrary herein, promptly after Closing, LICENSOR and LICENSEE shall establish standard approved formats for the Trademarks
(e.g., logo design), and Licensee may use the Trademarks in such approved formats, which, by default, shall be their current formats
as of Closing (each a (“ Trademark Format ”) without the need for further approval from LICENSOR.

8. Enforcement. If
LICENSEE learns that a third party may be infringing the Trademark, LICENSEE shall promptly provide LICENSOR with written
notice providing any details it knows about the use. LICENSEE shall not take any action without LICENSOR’s written consent. LICENSOR
shall decide what, if any, action to take, but shall have no obligation to take any action. LICENSEE shall, at LICENSOR’S
expense, cooperate with LICENSOR in any action it takes to stop infringement of Trademark. LICENSOR may settle any dispute relating to
the use of the Trademark without notice or compensation to LICENSEE; provided that any such settlement shall not impair the
rights of LICENSEE hereunder without LICENSEE consent, not to be unreasonably withheld, and LICENSOR shall retain the proceeds of any
settlement or proceeding.

9. Indemnification.

(a) Indemnification
by LICENSEE. LICENSEE agrees to indemnify, defend and hold LICENSOR and its Affiliates and the officers, directors, shareholders,
employees and agents of any of the foregoing harmless against any liability, losses, damages, penalties, claims, actions, suits, judgments
or settlements of any nature or kind (including reasonable costs of investigation, reasonable attorneys’, accountants’ and
expert witnesses’ fees, and reasonable costs and expenses), incurred by any such person by reason of LICENSEE’s use of the
Trademarks.

(b) Claims
Procedures. With respect to the foregoing indemnification obligations: (i) LICENSEE agrees promptly to notify and keep
LICENSOR fully advised with respect to any Claims; (ii) LICENSOR shall have the right to assume, at its sole expense, the defense
of a claim or suit made or filed against the LICENSEE; (iii)  LICENSOR may participate in the defense of such Indemnified Claim,
with counsel of its own choosing and at its own cost and expense; and, (iv) LICENSEE shall not compromise or settle any Claim without
LICENSOR’s prior written consent.

10. Intentionally
omitted.

11. Term
and Termination.

(a) Term.
This Agreement will commence as of the Effective Date and shall continue for five (5) years thereafter, unless terminated earlier
in accordance with the terms of this Agreement, or by mutual written agreement of the Parties hereto (the “ Term ”).
Notwithstanding the foregoing, if LICENSEE desires to extend the term for additional renewal periods of two (2) years, then LICENSEE
shall provide written notice to LICENSOR prior to expiration of the Term, and the parties shall discuss in good faith such extension.
Unless LICENSOR has a good faith and reasonable reason or justification for not approving such extension, the Term shall be extended
by such two (2) year periods.

cure the breach within thirty (30) days after LICENSEE receiving written notice thereof, this Agreement shall terminate at
the end of the thirty (30) day period; provided, however, that this Agreement shall not be terminated if, during such period, the LICENSEE
is diligently and in good faith taking reasonable steps to cure such breach.

of Termination. Upon expiration or termination of this Agreement, LICENSEE and all sublicensees shall immediately
discontinue manufacturing, selling, advertising, distributing, and using the products or services bearing or making a reference
to Trademark and any and all Advertising Materials, and terminate all agreements with manufacturers, distributors,
and others which relate to the manufacture, sale, distribution, and use of the foregoing. The provisions of Sections 3, 5(d), 9, 10, 11(e), 12, 13(e) and 14 herein shall survive any termination
or expiration of this Agreement. Notwithstanding the foregoing, absent a termination for material breach, LICENSEE shall have the
right to market and sell all remaining inventory branded in accordance with the terms and conditions hereof for a period not to exceed
twelve (12) months after expiration.

business operations and strategies, goods and services, customers, pricing, marketing, and other sensitive and proprietary information
(“ Confidential Information ”). The Receiving Party shall: (i) protect and safeguard the confidentiality of the
Disclosing Party’s Confidential Information with at least the same degree of care as the Receiving Party would protect its own

notifies LICENSOR of the identity and address of such sublicensee, and (ii) such sublicensee agrees in writing to be bound by,
and comply with, the terms and conditions no less protective of LICENSOR than this Agreement, with said sublicense terminating (a) if

parties hereto have entered into that certain Purchase Agreement, dated as of April 15, 2026 (the “ Purchase Agreement ”),
whereby Provider has agreed to sell to [Eurobio Scientific S.A./Recipient] certain assets of Provider related to the Quark Business and

B.            In
connection with the Purchase Agreement, Provider wishes to provide certain Transition Services (as defined below) to Recipient and Recipient
wishes to receive such Transition Services pursuant to the terms and conditions set forth in this Agreement.

NOW, THEREFORE, in consideration
of the foregoing and the mutual covenants, conditions and provisions contained herein and in the Purchase Agreement, and for other good
and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1.            TRANSITION
SERVICES.

(a) Scope
of Services. Subject to the terms and conditions of this Agreement, Provider will use reasonable best efforts to provide, or cause
its Affiliates to use reasonable best efforts consistent with good industry practice and with at least the same level of quality, timeliness
and care as provided to the Quark Business during the twelve (12) month period prior to the Effective Date to provide, to Recipient the
transition services described in Exhibit A (each, a “ Transition Service ” and collectively, the
“ Transition Services ”) during the applicable service period set forth on Exhibit A (each, a “ Transition
Period ”), in accordance with and subject to any applicable limitations or conditions set forth on Exhibit A.
The parties hereto acknowledge the transitional nature of the Transition Services and Recipient agrees to use reasonable best efforts
to transition, as promptly as practicable following the Closing, each Transition Service to its own internal organization or to obtain
services from alternative third-party sources in lieu of the Transition Services provided by Provider. This Agreement imposes no obligation
on Provider to perform any services other than the Transition Services expressly described in this Agreement or in Exhibit A attached hereto, as it may be amended or supplemented as mutually agreed by the parties hereto from time to time in accordance with terms
of this Agreement. Provider will use reasonable best efforts to perform the Transition Services in a manner generally consistent with,
and with the same standard of care, in all material respects and without degradation in service levels, as such services were provided
to the Quark Business during the twelve (12) month period prior to the Effective Date, subject to Recipient fulfilling its obligations
under this Agreement and providing sufficient information, resources, and access as reasonably necessary for Provider to satisfy its
obligations under this Agreement. Under no circumstances will Provider be expected to modify its existing systems or processes, vendor
arrangements or business terms and conditions from those in existence prior to the Effective Date except to the extent reasonably necessary
to facilitate the transition and separation of the Quark Business as contemplated by this Agreement. Notwithstanding anything in this
Agreement to the contrary, Provider will have no obligation to perform any custom development work or implement any new product or service
features or functionalities in connection with the provision of the Transition Services other than reasonable configuration, data extraction,
migration assistance and knowledge transfer necessary to the transition and separation of the Quark Business as contemplated by this
Agreement.

(b) Restricted
Contract Assets; Shared Contracts.

(i) In
the event that Provider is unable to assign to Recipient (or its affiliate, as applicable) a supply or vendor agreement that is exclusively
related to the Quark Business as contemplated pursuant to Section 2.5 of the Purchase Agreement, then for a period of up to twenty-four
(24) months after the Closing Date (a “ Quark Supply Agreement ”), Provider and Recipient shall work together
in good faith and use best efforts to ensure that Recipient continues to receive the products or services supplied under such Quark Supply
Agreement by implementing one or more of the following arrangements: (a) Provider shall assist Recipient in obtaining its own replacement
supply agreement with the applicable supplier or vendor on commercially reasonable terms, or, to the extent deemed necessary by Recipient,
an alternative supplier or vendor that can provide substitute products or services for those provided under the Quark Supply Agreement,
as agreed by the parties acting reasonably and in good faith (which assistance from Provider shall include providing the introduction
to the relevant supplier or vendor and using commercially reasonable efforts to facilitate the consummation of the replacement supply
agreement between Recipient and such supplier or vendor), (b) to the extent Provider is not restricted under the applicable Quark
Supply Agreement, Provider shall continue to order and purchase the products under the Quark Supply Agreement, at Recipient’s direction,
and Provider shall resell such products to Recipient, provided that Recipient shall reimburse Provider only for its acquisition costs
therefor with no mark-up, or (c) in the case neither of the approaches set forth in (a) or (b) are feasible, then Provider
will continue to order and purchase products under such Quark Supply Agreement, at Recipient’s direction, and Provider shall enter
into a manufacturing agreement with Recipient (or one of its Affiliates) in the form attached hereto as Exhibit B, and a
distribution agreement with Recipient (or one of its Affiliates) in the form attached hereto as Exhibit C, providing for
the supply of the products purchased by Provider under the Quark Supply Agreement to the Recipient (or one of its Affiliates), at the
cost paid by Provider for such products without markup, in order for Recipient or such Affiliate to manufacture the products of the Quark
Companies with such supplied products in the same manner as such products are manufactured by the Quark Companies on the Effective Date
and to appoint Recipient (or one of its Affiliates) as Provider’s exclusive distributor for such finished products, with Recipient
(or such Affiliate) being entitled to keep all proceeds from the sale of any such finished products under the Distribution Agreement
without payment of any royalties or other amounts to Provider.

(ii) In
the case of any Shared Contract under which any rights or benefits are relied upon by the Quark Companies or are required for the conduct
of the Quark Business, as determined by Recipient in its discretion, the Parties will cooperate with each other in good faith and use
commercially reasonable efforts to facilitate the negotiation and entry by Recipient (or one of Quark Companies) into a new agreement
with the same counterparty on equivalent economic and other terms with the same or a reasonably acceptable replacement vendor (as mutually
considered by Provider and Recipient, and determined by Recipient in its reasonable discretion) for the provision by such vendor of the
same or materially similar products or services to Recipient or the applicable Quark Company following the Closing as are provided to
such Quark Company as of the Effective Date and otherwise upon the applicable vendor’s standard terms and conditions (or such other
terms and conditions as may be negotiated by Recipient with such vendor with the reasonable co-operation and assistance of Provider)
(each such new Contract, a “ Replacement Contract ”), with such Replacement Contract to become effective as soon
as practicable following the Closing. Pending the entry by the Recipient or the applicable Quark Company into such Replacement Contract,
subject to the terms and conditions of this Agreement, Provider will use commercially reasonable efforts to make available the assets,
products or services under the applicable Shared Contract to Recipient to the same extent as such assets, products or services were provided
to the relevant Quark Company prior to the Closing, as a Transition Service hereunder and the parties hereto will update Exhibit A
to include such Transition Service, unless the parties mutually agree on an alternative arrangement that would give Recipient the benefit
of the same or a substantially similar service. In the case of a Shared Contract under which the relevant Quark Company is required to
pay for such assets, products or services directly to the applicable vendor, whether pursuant to the terms of such Shared Contract, or
any insertion order, statement of work, order form or similar document entered into by such Quark Company under such Shared Contract
(each, a “ Recipient SOW ”), Recipient hereby agrees to timely discharge such payments to the relevant vendor
in full in accordance with the terms of such Shared Contract. In the case of any Shared Contract under which Provider pays the relevant
vendor for the assets, products or services under such Shared Contract that are used or relied on by any Quark Company, Recipient will
pay the Fees as set forth in Exhibit A of this Agreement for such Transition Service. The Transition Period for the Transition
Services hereunder provided in connection with Shared Contracts will not extend beyond the earlier of (A) such time as the Replacement
Contract has been obtained or (C) the date that is twenty-four (24) months following the Closing Date, unless otherwise agreed
by Provider, such agreement not to be unreasonably withheld, conditioned or delayed.

2

(iii) Provider
will not be required to renew or replace any Shared Contract (in its entirety or with respect to the portion of the assets, products
or services provided thereunder that are used by the Quark Companies) for which Transition Services are provided hereunder that expires
or is due for renewal during the term of this Agreement; provided that Provider shall use commercially reasonable efforts to support
Recipient in obtaining replacement arrangements and shall not allow any Shared Contract to terminate due to Provider’s breach or
voluntary action. During the Transition Period, Provider will not materially modify the pricing or other material terms of, or terminate
(other than as set forth in the preceding sentence), any portion of a Shared Contract, or any Recipient SOW, that relate to assets, products
or services provided to Recipient hereunder as a Transition Service without Recipient’s prior written approval (such approval not
to be unreasonably withheld, delayed or conditioned) except for any such modification that applies in the same manner to Provider’s
use of such assets, products or services in its other businesses

(iv) Recipient
will not renew any Recipient SOW or enter into any new Recipient SOW during the Transition Period applicable to the relevant Shared Contract
without Provider’s prior written approval.

(c) Subcontractors;
Personnel.

(i) Provider
may satisfy its obligation to provide the Transition Services hereunder by (A) causing one or more of its Affiliates to provide
such Transition Services or (B) at reasonable expense, subcontracting any of the Transition Services or any portion thereof to,
or procuring any of the Transition Services or portion thereof from, any other Person; provided that, in each case of clauses
(A) and (B), Provider remains liable for the performance of such subcontractors and their compliance with the terms of this Agreement;
and, provided, that, any such subcontractors are approved by Recipient as having appropriate skill, experience and training consistent
with past practice.

(ii) Provider
will have the right, in its discretion, to (A) designate which personnel it will assign to perform each Transition Service; provided,
that, Provider shall assign personnel with appropriate skill, experience and training consistent with past practice, and (B) remove
and replace such personnel at any time. In performing their respective duties hereunder, all such employees, contractors and other representatives
of Provider and its Affiliates (excluding, for the avoidance of doubt, the Quark Companies and their personnel) will be under the direction,
control and supervision of Provider and its Affiliates (excluding the Quark Companies and their personnel), and Provider and such Affiliates
will have the sole right to exercise all authority with respect to the employment (including termination of employment), engagement,
assignment and compensation of such employees, contractors and representatives. Provider shall use commercially reasonable efforts to
provide reasonable prior notice of any material changes to key personnel involved in the provision of Transition Services.

3

(d) Interpretation.
Recipient acknowledges that Provider is not in the business of providing services like the Transition Services on a commercial arm’s-length
basis to independent third parties, and that this Agreement is only required for specific circumstances related to the consummation of
the Transactions on a transitional basis only. The provisions of this Agreement will be interpreted in that context.

2.            COOPERATION.

(a) Cooperation.
The parties hereto will use reasonable best efforts to cooperate with each other in all matters relating to the provision and receipt
of the Transition Services. Subject to the terms and conditions of this Agreement, and subject to Recipient’s compliance with Provider’s
information security, access, nondisclosure and confidentiality and other reasonable policies and requirements, such cooperation will
include exchanging information, providing necessary access to people, equipment and systems, and cooperating with respect to obtaining
and providing all consents, licenses, sublicenses, approvals, and/or rights reasonably necessary to permit each party to perform its
obligations hereunder.

(b) Administration.
Each of the parties hereto will appoint a representative to serve as the main point of contact for such party for the purposes of this
Agreement for each individual Transition Service as set forth on Exhibit A (such person, the “ Transition Representative ”).
At its discretion, each party hereto may replace or appoint a successor Transition Representative with written notice to the other party.
The relevant Transition Representatives for the Transition Services hereunder will meet to discuss the performance of the Transition
Services on weekly basis within the first ninety (90) days if the Closing and then on a monthly basis to ensure the orderly provision
of the Transition Services, and in any event at least monthly, and will have the authority to address and remedy problems related to
the provision of the Transition Services to the extent consistent with this Agreement.

(c) Disputes.
The parties hereto will work together in good faith to resolve all disputes under this Agreement. Disputes will be first escalated to
the managers of each party with the most direct responsibility for the dispute and the Transition Representative. Any disputes unresolved
after 10 business days will then be escalated to the respective managers’ next level of management. If such second level of managers
cannot resolve the dispute within the next 10 business days thereafter, then the dispute will be escalated to (i) the chief executive
officer, chief financial officer or chief operational officer of Recipient and (ii) a senior-level executive of Provider. If such
persons cannot resolve the dispute within the next 10 business days, then any party may pursue any available legal remedy and resolution
of such dispute pursuant to Section 9(l).

(d) Access
and Confidentiality. While accessing any data processing or communications services or facilities of the other party, each party
will, and will cause its Representatives and subcontractors to, comply in all material respects with the other party’s corporate
information and physical security policies (including policies with respect to protection of proprietary information and other policies
regarding the use of computing resources) as in effect and notified to such party from time to time. Recipient will not attempt to gain
access to or use any information or systems of Provider and its Affiliates except as expressly authorized by Provider. The parties hereto
acknowledge that use and disclosure of each party’s confidential information will be governed by the terms of the Purchase Agreement
and the Mutual Non-Disclosure Agreement dated effective as of November 20, 2024 between Provider and Eurobio Scientific SA/Recipient
(the “ Confidentiality Agreement ”).

4

(e) Identification
of Dependencies. Within two (2) weeks after the execution of the Purchase Agreement, Provider shall deliver to Recipient a
first draft of a dependency map that lists out all known interdependencies relating to the Transition Services. During the period following
delivery of such draft dependency map and continuing through the Closing, Provider and Recipient shall use reasonable best efforts to
update such dependency map, including adding additional detail as needed.

(f) Cybersecurity
and Data Protection. Following execution of the Purchase Agreement and continuing through the term of this Agreement, Provider shall
use reasonable best efforts to maintain its data security and cyber security systems and processes with at least the same level of quality,
timeliness and care as Provider maintained during the twelve (12) month period prior to the Effective Date.

3.            FEES
AND PAYMENT.

(a) Fees.
As consideration for providing the Transition Services, Recipient will pay, and Buyer will cause Recipient to pay, to Provider the amount
set forth on Exhibit A for each Transition Service (“ Fees ”) in accordance with the invoicing procedures
set out in Section 3(d). The parties hereto acknowledge and agree that the Fees for Transition Services that pertain to
Transition Services performed by personnel of Provider will be calculated and charged on the basis of Provider’s Fully Burdened
Cost for the relevant Provider personnel (as determined in a manner consistent with the historical methods of Provider’s allocation
of costs to the Quark Business), in accordance with the invoicing procedures set out in Section 3(c). “ Fully Burdened
Cost ” means the fully-burdened costs of the personnel of Provider (or any of its Affiliates) providing Transition Services
hereunder which, in the case of contractors, shall mean the direct compensation paid to contractors and, in the case of employees, shall
mean the Employee Costs, which, in each case, (i) are paid or payable to such personnel solely in respect of their provision of
the Transition Services and (ii) will be charged at Provider’s actual cost, provided, that, such costs shall be consistent
with Provider’s historical allocation methodologies and shall not include any duplicative overhead or costs not reasonably attributable
to the provision of the Transition Services), plus an overhead charge in an amount to be agreed as set forth in Exhibit A (such
overhead charge, the “ Markup ”). “ Employee Costs ” shall mean, with respect to any
employee of Provider (or any of its Affiliates) providing Transition Services hereunder, the sum of (i) his or her salary, wages
(including wages in respect of paid vacation or paid time off), bonuses, cash incentive compensation, commissions and equity incentive
compensation, (ii) Provider’s (or its Affiliate’s) share of the premiums (or equivalents) for workers compensation,
unemployment, fringe and welfare benefits under Provider’s (or its Affiliate’s) employee benefit plans (for clarity, reduced
by the contributions for coverage paid by the applicable employee), (iii) Provider’s (or its Affiliate’s) employer
non-elective and matching contributions to Provider’s tax-qualified defined contribution retirement plan, and (iv) Provider’s
(or its Affiliate’s) share of payroll and other employment taxes. Based on projected scope and lengths outlined on Exhibit A, the
aggregate Fees will be capped at USD $1 million dollars (the “ Cap ”), provided that if, at any time, it becomes
reasonably apparent that the aggregate Fees will surpass the Cap, then the parties will, at the election of either one of them, negotiate
in good faith an alternate Cap, provided, however, that the Fees as determined above shall continue to accrue until such alternate Cap
is agreed to.

(b) Upon
Recipient’s request, Recipient and Provider will collaborate together in good faith to establish budgeting and cost forecasting
procedures to avoid cost overages or otherwise to facilitate delivery of the Transition Services.

5

(c) Out
of Pocket Costs. In addition, Recipient will further reimburse to Provider any additional, incremental or increased fees, and direct
or indirect costs or expenses, incurred by Provider in connection with providing a Transition Service, including license fees or other
payments to third-party vendors and service providers, costs and expenses of maintaining redundant instances, paying additional or higher
pricing or rates under new or replacement Contracts for the Quark Business or with respect to Restricted Split Interests, purchasing
additional data storage or incurring technical standup costs and other costs to facilitate the separation of the Recipient and the Business
from the other businesses of Provider and its Affiliates, in each case, to the extent reasonably necessary and actually incurred in connection
with the provision of the Transition Services and supported by reasonable documentation (collectively, “ Out-of-Pocket Costs ”),
which Out-of-Pocket Costs will be reimbursed by Recipient in accordance with the invoicing procedures in Section 3(d). The
parties will coordinate to generally to ensure that expenses under this Agreement are in line with historical expenses and Provider will
notify Recipient in advance of any exceptional expenses that may be incurred to enable Recipient to approve any such expenses in advance.
Upon Recipient’s request, Recipient and Provider will collaborate together in good faith to establish spending thresholds for Out
of Pocket expenses above which prior approval is required.

(d) Transition
Service Adjustment. If an adjustment in the time or work performed as part of the Transition Services is required after Provider
commences the Transition Services, the applicable scope of work, time and compensation will be agreed in writing by Provider and Recipient
prior to the commencement of additional work or any extension of the Transition Period, as applicable.

(e) Payment.
All Fees and Out-of-Pocket Costs will be payable to Provider on a monthly basis within 30 days following Recipient’s receipt of
Provider’s monthly invoice for Fees and Out-of-Pocket Costs incurred during the applicable calendar month. All payments hereunder
will be paid in U.S. Dollars and made by wire transfer of immediately available funds to a bank account specified by Provider in writing.
All Fees and Out-of-Pocket Costs owed under this Agreement and not paid when due will accrue late charges at the rate of 1.5% per month,
or the highest rate permitted by applicable Law, whichever is lower. If Recipient discovers an error or omission in any invoice, Recipient
will provide prompt written notice to Provider and Provider’s Transition Representative of such error or omission for resolution
in accordance with Section 2(c). Recipient shall have the right, upon reasonable prior notice, to audit Provider’s
records relating to Fees and Out-of-Pocket Costs no more than once annually.

(f) Extension
Fee. Provider will have no obligation to provide any Transition Service after expiration of the applicable Transition Period for
such Transition Services.

(g) Taxes.
Except as otherwise noted on the relevant invoice, the Fees do not include any Taxes. Recipient will be responsible for and pay any and
all federal, state or local sales, use, value-added, goods and services and similar Taxes, duties, charges or levies (and any related
interest and penalties) imposed on, or in connection with the provision of the Transition Services hereunder, but excluding any Taxes
measured by or imposed on the Provider’s net income. All payments made by or on behalf of Recipient under this Agreement will be
made without deduction or withholding for any Taxes, unless Recipient is required to deduct or withhold such Taxes under applicable Law.
If Recipient is required by any applicable Law or regulation to withhold any amount for Taxes from any payment due to Provider under
this Agreement, then Recipient will (i) make such withholdings as are required by applicable Law, (ii) timely pay the full
amount deducted or withheld to the appropriate Governmental Authority and (iii) pay such additional amounts to the Provider as
may be necessary so that the net amount received by Provider after such withholding will not be less than the amount Provider would have
received if such deductions or withholding had not been made. At Provider’s request, Recipient will provide Provider with reasonably
satisfactory documentation evidencing the payment to the appropriate Governmental Authority of any amounts so withheld or deducted.

(h) No
Set-Off. Each party hereto hereby acknowledges and agrees that it has no right under this Agreement to set off, discount or otherwise
reduce or refuse to pay any amounts owed to the other party under this Agreement against any other amount owed to it by the other party,
whether under this Agreement, the Purchase Agreement, other Transaction Documents or otherwise; provided that Recipient may set off amounts
finally determined to be owed by Provider pursuant to this Agreement.

4.            TERM
AND TERMINATION; SUSPENSION.

(a) Term.
Unless earlier terminated, this Agreement is effective beginning on the Effective Date and will remain in effect until termination or
expiration of the last to expire Transition Period.

(b) Termination
for Convenience. Recipient will use commercially reasonable efforts to transition the Quark Companies and their Affiliates from reliance
upon, and terminate, the Transition Services that Recipient is receiving hereunder as soon as reasonably practicable following the Effective
Date. Unless otherwise set forth on Exhibit A, Recipient may terminate any or all Transition Service(s), or any portion
thereof, upon 30 days’ written notice to Provider, without further liability or cost to Recipient; provided that, notwithstanding
the foregoing, Recipient will remain liable for non-cancellable costs that were incurred in good faith, are documented, and were not
reasonably avoidable following such notice incurred or committed to be incurred by Provider in respect of any such Transition Services
for the then current Transition Period; provided that in the event of early termination, any fixed or monthly fees agreed for Transition
Services shall be prorated to correspond to the actual Transition Period. Notwithstanding anything in the foregoing to the contrary,
Recipient acknowledges that certain Transition Services are dependent upon the provision of other Transition Services and the termination
of one Transition Service (in whole or in part) may not be possible without the termination or reduction of a number of other Transition
Services (in whole or in part) and, that in the event any such a termination or reduction, Provider will notify Recipient thereof in
advance in writing, permitting Recipient a reasonable period and in any event not less than ten (10) Business Days, to adjust its
approach continue Transition Services otherwise planned for termination. In the event Recipient has been so notified and continues in
its plan for termination of the related Transition Service, Provider may, upon written notice to Recipient, terminate or reduce any other
Transition Service that it has notified Recipient is dependent upon the Transition Service that has been terminated by Recipient.

(c) Termination
for Cause. Either Provider or Recipient may terminate this Agreement in the event that the other party materially breaches this Agreement
and such material breach remains uncured for 30 days following receipt of written notice of such breach by the non-breaching party. Provider
may further terminate a Transition Service hereunder with notice to Recipient in the event that Provider receives notice from a counterparty
to any Shared Contract in connection with which such Transition Service is provided that the provision of Transition Services under such
Contract by Provider constitutes a breach of such Shared Contract or if any actions or omissions of Recipient in connection with such
Transition Service have caused or are reasonably expected to cause a breach of such Shared Contract; provided, that, Provider shall provide
prompt written notice of any such counterparty notice and shall take commercially reasonable steps to mitigate any impact of such termination
as contemplated through alternative supply arrangement or otherwise in Section 1(b) above.

(d) Partial
Termination. In the event of any termination or expiration with respect to one or more of the Transition Services, but not all of
the Transition Services, this Agreement will continue in full force and effect with respect to any Transition Service(s) not terminated
or expired in accordance with this Agreement. Upon termination of this Agreement, or upon the termination or expiration of all of the
Transition Services in accordance with this Section 4, Provider will cease to perform the Transition Services, and Recipient
will pay to Provider all sums due to Provider pursuant to this Agreement for the Transition Services performed through the effective
date of termination, if any. Termination of this Agreement or termination or expiration of any Transition Service in accordance with
this Section 4 will not relieve any party from its obligations or liabilities arising hereunder prior to the date of such
termination or expiration, nor will it affect the rights of any party with respect to any claims or damages it may have suffered as a
result of any breach of this Agreement by the other party.

7

(e) Effect
of Termination. Sections 3, 4(d), 4(e), 6(a), 7, 8 and 9 will survive any expiration
or termination of this Agreement.

5.            COMPLIANCE.

(a) Restrictions
on Services. Each party hereto will comply in all material respects with all applicable Laws that govern the conduct of its own business
operations with respect to the performance of its obligations under this Agreement and receipt and use of Transition Services, as applicable.
Notwithstanding anything in this Agreement to the contrary, Provider will not be obligated to provide a Transition Service that, in Provider’s
reasonable discretion, (i) would be unlawful for Provider to provide under any applicable Law or (ii) would breach the terms
of any existing agreement between Provider and any third party or that would otherwise require the consent or similar approval of a third
party; provided that Provider shall use commercially reasonable efforts to mitigate or overcome such limitation and minimize disruption
to Recipient. If Provider is unable to provide a Transition Service due to the limitations described in this Section 5(a),
the parties will work together and use commercially reasonable efforts to arrange a substitute means of obtaining such service or obtaining
replacement or substitute agreements that would permit Provider to provide each such Transition Service, in each case at Recipient’s
sole cost and expense. In the event, and during the period, that Provider or its Affiliates is wholly or partially prevented from, or
delayed in, providing one or more of the Transition Services by applicable Law or by order of a Governmental Authority (a “ Legal
Prohibition ”), or because providing such services would breach the terms of any existing agreement between Provider and
any third party or would otherwise require the consent or similar approval of a third party (“ Contractual Restriction ”),
(A) neither Provider nor its Affiliates will be obligated to deliver the affected Transition Services during such period, (B) Provider
will promptly provide Recipient with notice of any Transition Services that will be suspended pursuant to clause (A), stating the
date and extent of such suspension and the cause thereof and (C) the parties hereto will use their commercially reasonable efforts
to resolve the Legal Prohibition or Contractual Restriction. The parties hereto will cooperate and use commercially reasonable efforts
to minimize the impact of any Legal Prohibition or Contractual Restriction on the provision of Transition Services hereunder; provided that such efforts need not include expenditure of funds, the payment of consideration or the grant of rights or other accommodations
to third parties. Provider shall promptly notify Recipient in writing of any anticipated interruption and shall cooperate in implementing
reasonable alternative arrangements.

(b) Contractual
Obligations. Recipient will comply with and perform all terms and conditions of the Quark Supply Contracts and the Shared Contracts
as they relate to Recipient’s receipt and use of Transition Services, including, without limitation, complying with the terms and
conditions of such Contract and discharging or reimbursing Provider for all payment obligations set forth in any such Contract, or any
statement of work, order form or similar document thereunder, as they relate to the receipt by Recipient or its Affiliates of the benefits
of such Transition Services under such Contracts, as may be further described in Exhibit A.

(c) No
Regulatory Advice. Notwithstanding anything in this Agreement to the contrary or the accompanying exhibits and schedules, Provider
is not responsible for ensuring Recipient’s regulatory and legal compliance under applicable Law and the parties hereto agree that
the Transition Services are not a substitute for Recipient’s performance of any such compliance obligation or the engagement of
appropriate advisors to assist with any such compliance obligation. All regulatory and legal compliance matters relating to Recipient’s
use of the Transition Services will be exclusively the responsibility of Recipient. All liability and third party claims arising from
regulatory and legal compliance matters relating to the business of Recipient will be exclusively the liability of Recipient.

8

6.            INTELLECTUAL
PROPERTY.

(a) No
Transfer. Subject to Section 6(b), this Agreement and the performance of the Transition Services hereunder will not
affect, or result in the transfer of, any rights in or to or the ownership of any Intellectual Property or other rights of either party.
No party hereto will gain any rights of ownership of any Intellectual Property or other property owned by any other party by virtue of
this Agreement or the provision of the Transition Services hereunder, by implication, estoppel or otherwise.

(b) License.
Recipient, on behalf of itself and its Affiliates, hereby grants to Provider (and solely for Provider to provide the Transition Services,
to Provider’s subcontractors) a non-exclusive, worldwide, non-transferable, fully paid-up, royalty-free license, under all Intellectual
Property owned or controlled by Recipient or any of its Affiliates, solely for the purpose of providing the Transition Services.

7.            LIABILITY.

(a) Disclaimer.
EXCEPT THAT PROVIDER REPRESENTS THAT IT SHALL PERFORM THE TRANSITION SERVICES IN ACCORDANCE WITH SECTION 1(a), THE TRANSITION
SERVICES ARE PROVIDED BY PROVIDER “AS IS” AND PROVIDER MAKES NO EXPRESS OR IMPLIED WARRANTIES OR GUARANTEES WITH RESPECT
TO THE TRANSITION SERVICES. NO STATUTORY WARRANTY OF MERCHANTABILITY, QUALITY, FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT OR OTHERWISE
WILL APPLY TO THE TRANSITION SERVICES.

(b) Limitation
of Liability. IN NO EVENT WILL PROVIDER BE LIABLE TO RECIPIENT WITH RESPECT TO THE PERFORMANCE OF ANY TRANSITION SERVICES UNDER THIS
AGREEMENT WHETHER UNDER ANY CONTRACT, NEGLIGENCE, STRICT LIABILITY OR OTHER LEGAL OR EQUITABLE THEORY, FOR ANY, SPECIAL, PUNITIVE, EXEMPLARY, INCIDENTAL
OR CONSEQUENTIAL DAMAGES, LOST PROFITS OR COST OF PROCUREMENT OF SUBSTITUTE PERSONNEL, TECHNOLOGY OR SERVICES, IN EACH CASE, WHETHER
OR NOT PROVIDER HAS BEEN ADVISED OF OR WAS AWARE OF THE POSSIBILITY OF SUCH DAMAGES, UNLESS CAUSED BY THE FRAUD OF PROVIDER, P ROVIDED
THAT NOTHING IN THIS SECTION SHALL LIMIT PROVIDER’S LIABILITY FOR (i) FRAUD, OR (ii) GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT.

(c) Basis
of Bargain. THE FOREGOING LIMITATIONS WILL APPLY NOTWITHSTANDING ANY FAILURE OF ESSENTIAL PURPOSE OF ANY LIMITED REMEDY PROVIDED
HEREIN. RECIPIENT RECOGNIZES AND AGREES THAT THE WARRANTY DISCLAIMERS AND LIABILITY AND REMEDY LIMITATIONS IN THIS AGREEMENT ARE MATERIAL
BARGAINED FOR BASES OF THIS AGREEMENT AND THAT THEY HAVE BEEN TAKEN INTO ACCOUNT AND REFLECTED IN THE DECISION BY EACH PARTY TO ENTER
INTO THIS AGREEMENT.

8.            INDEMNITY.
Recipient will indemnify and hold harmless Provider for all Losses arising out of resulting from, and will defend, at its expense, any
claim brought against Provider by a third party to the extent that such claim is based upon: (a) any breach by Recipient of Section 5(a) or Section 5(b), (b) any Taxes, including any interest and penalties, that are the responsibility of Recipient under Section 3(f), (c) any negligence or misconduct of Recipient in connection with its use of the Transition Services,
(d) claims that Recipient’s use of the Transition Services infringes or violates any statutory, contractual or common law
right of any third party or (e) any personal injury caused by Recipient in connection with the Transition Services, to the extent
not resulting from the gross negligence or willful misconduct of Provider; and Recipient will pay, and Buyer will cause Recipient to
pay, any costs, damages, attorneys’ fees or other Losses of the parties hereto attributable to such claim. Provider shall indemnify
and hold harmless Recipient from and against Losses arising from Provider’s gross negligence, willful misconduct or fraud in connection
with the performance of the Transition Services.

9.            GENERAL.

(a) Assignment.
Neither this Agreement nor any of the rights, interests or obligations hereunder will be assigned, in whole or in part, by operation
of law or otherwise, by any party without the prior written consent of the other party. Notwithstanding the foregoing, Recipient may
assign this Agreement to an Affiliate, and either Provider or Recipient may assign or transfer this Agreement to a third-party that succeeds
to all or substantially all of such party’s business and assets relating to the subject matter of this Agreement, whether by sale,
merger, operation of law or otherwise. Subject to the foregoing, this Agreement will be binding upon, inure to the benefit of, and be
enforceable by, the parties hereto and their successors and permitted assigns. Any purported assignment not permitted under this Section 9(a) will
be null and void.

(b) Excusable
Non-performance. The obligations of Provider to provide Transition Services will be suspended to the extent that Provider is prevented
from providing such Transition Services by any cause beyond the reasonable control of Provider, including acts of God, civil disturbances,
acts of war or conditions arising out of or attributable to war (whether declared or undeclared), terrorism, rebellion, insurrection,
riot, invasion, pandemics, fire, storm, flood, earthquake, denial of service and other malicious attacks, power outages, strikes, lockouts
or other labor or industrial disputes. In the event of any such suspension, Provider will give notice of such suspension to Recipient
as soon as reasonably practicable, stating the date and extent of such suspension and the cause thereof and will use commercially reasonable
efforts to overcome such cause and resume the provision of such Transition Services after the cessation of such cause if the Transition
Period for such Transition Services has not expired. If Provider is excused from providing any Transition Service in accordance with
the terms of this paragraph, Recipient’s sole and exclusive remedy will be to acquire such services from any substitute source,
at Recipient’s sole expense.

(c) No
Third-Party Beneficiaries. Unless otherwise expressly provided, no provisions of this Agreement are intended or will be construed
to confer upon or give to any other person or entity, other than the parties hereto and their Affiliates, successors and permitted assigns,
any rights, remedies or other benefits under or by reason of this Agreement.

(d) Non-Exclusive
Remedies. Except as expressly set forth in this Agreement, the exercise by any party hereto of any remedy under this Agreement will

by law, given the fundamental intentions of the parties hereto and the remaining provisions of this Agreement will remain in full force
and effect.

(f) Waiver.
A party’s failure to enforce any provision of this Agreement will not constitute a waiver of future enforcement of that or any
other provision. No waiver of any provision of this Agreement will be effective unless it is in writing and signed by the party granting
the waiver.

(g) Notice.

(h) Purchase
Agreement. Neither the making nor the acceptance of this Agreement will enlarge, restrict or otherwise modify the terms of the Purchase
Agreement or any other Transaction Document entered into by any of the parties, or constitute a waiver or release by Recipient or Provider
of any liabilities, obligations, covenants or commitments imposed upon either party by the terms of the Purchase Agreement or such other
Transaction Documents. In the event of any conflict between the provisions of this Agreement (including the exhibits hereto) and the
provisions of the Purchase Agreement, on the other hand, the Purchase Agreement will control except that in the case of any conflict

making specific reference to this Agreement signed by each of the Provider and Recipient.

it being understood and agreed that all parties hereto need not sign the same counterpart. The delivery by facsimile or by electronic
delivery in PDF format of this Agreement with all executed signature pages (in counterparts or otherwise) will be sufficient to
bind the parties hereto to the terms and conditions set forth herein. All of the counterparts will together constitute one and the same
instrument and each counterpart will constitute an original of this Agreement.

(l) Governing
Law; Dispute Resolution. This Agreement will be governed by, and construed in accordance with, the laws of the State of New York
without reference to such state’s principles of conflicts of law that would refer a matter to a different jurisdiction. Any legal
action or proceeding arising out of or relating to this Agreement, the transactions contemplated hereby or thereby, or the actions of
the parties hereto in the negotiation, administration, performance and enforcement hereof and thereof, will be resolved in accordance
with Section 9.16 of the Purchase Agreement.
