each “an IP Action”.

16.2 XDx Action

XDx shall have the right, but not the obligation, to take action in the prosecution, defence, prevention, or termination of any IP Action. Should XDx elect to commence or defend legal proceedings in respect of the IP Action and Diaxonhit is joined as party in any such proceedings, Diaxonhit shall have the right to approve the counsel selected by XDx to represent the parties, such approval not to be unreasonably withheld. The expenses of such legal proceedings, including any reasonable expenses of Diaxonhit incurred in conjunction with such legal proceedings or the settlement thereof, shall be paid for entirely by XDx and XDx shall hold Diaxonhit free, clear and harmless from and against any and all costs of such litigation, including reasonable attorney’s fees (but excluding any independent attorney fees incurred by Diaxonhit in addition to the approved attorney fees). XDx shall not compromise or settle such litigation in a matter that would admit fault on behalf of Diaxonhit or adversely affect Diaxonhit’s rights without the prior written consent of Diaxonhit, which consent shall not be unreasonably withheld or delayed. In the event XDx exercises its right to conduct legal proceedings pursuant to this clause 16.2, it shall first reimburse itself out of any sums recovered in such suit or in settlement thereof for all out of pocket costs and expenses of

22

every kind and character, including without limitation attorney’s fees and the costs of Diaxonhit payable pursuant to this clause 16.2, incurred in the conduct of any such legal proceedings.

16.3 Diaxonhit Action

If XDx does not take action in the prosecution, defence, prevention, or termination of any IP Action pursuant to clause 16.2 above, and has not commenced negotiations with the other party for the discontinuance of said IP Action, within ninety (90) days after receipt of notice to XDx by Diaxonhit of the existence of an IP Action, Diaxonhit may elect to do so. Should Diaxonhit elect to commence or defend legal proceedings in respect of the IP Action and XDx is joined as party in any such legal proceedings, XDx shall have the right to approve the counsel selected by Diaxonhit to represent the Parties, such approval not to be unreasonably withheld or delayed. The expenses of such suit or suits that Diaxonhit elects to bring, including any expenses of XDx incurred in conjunction with the prosecution of such suits or the settlement thereof, shall be paid for entirely by Diaxonhit, as the case may be, and Diaxonhit shall hold XDx free, clear and harmless from and against any and all costs of such litigation, including reasonable attorney’s fees (but excluding any independent attorney fees incurred by XDx in addition to the approved attorney fees). Diaxonhit shall not compromise or settle such litigation without the prior written consent of XDx, which consent shall not be unreasonably withheld or delayed. In the event Diaxonhit exercises its right to pursue legal proceedings pursuant to this clause 16.3, Diaxonhit shall first reimburse themselves out of any sums recovered in such suit or in settlement thereof for all out of pocket costs and expenses of every kind and character, including without limitation attorney’s fees and the costs of XDx payable pursuant to this clause 16.3, incurred in the prosecution of any such suit. If, after such reimbursement, any funds shall remain from said recovery, then XDx shall be entitled to receive 25% of such funds and the remaining 75% of such funds shall be retained by Diaxonhit.

16.4 Each Party shall always have the right to be represented by counsel of its own selection and at its own expense in any legal proceedings conducted under this clause 16 by the other party in respect of an IP Action.

16.5 Each party agrees to cooperate fully in any action under this clause 16 which is controlled by the other party, provided that the controlling party reimburses the cooperating party promptly for any costs and expenses incurred by the cooperating party in connection with providing such assistance.

16.6 If a party lacks standing and the other party has standing to bring any such suit, action or proceeding, then such other party shall do so at the request of and at the expense of the requesting party. If either party determines that it is necessary or desirable for another party to join any such suit, action or proceeding, the other party shall execute all papers and perform such other acts as may be reasonably required in the circumstances.

17. REPRESENTATIONS AND WARRANTIES

20. INDEMNITY ACTIONS

20.1 An Indemnified Party shall promptly and without delay give the Indemnifying Party prompt written notice of any Loss or discovery of fact upon which such Indemnified Party intends to base a request for indemnification under this Agreement (an “Indemnification Claim Notice”). In no event shall the Indemnifying Party be liable for any Loss that results from any delay in providing the Indemnification Claim Notice. Each Indemnification Claim Notice shall contain a description of the claim and the nature and amount of the Loss claimed (to the extent that the nature and amount of such Loss is known at such time). The Indemnified Party shall furnish promptly to the Indemnifying Party copies of all papers and official documents received in respect of any such Loss. For the avoidance of doubt, all indemnification claims in respect of a Party, its Affiliates or their respective directors, officers, employees and agents (each, an “Indemnitee”) shall be made solely by such Party to this Agreement.

20.2 The obligations of an Indemnifying Party under this Agreement with respect to a Third Party Claim shall be governed by and be contingent upon the following:

(A) Assumption of Defence

At its option, the Indemnifying Party may assume the defence of any Third Party Claim by giving written notice to the Indemnified Party within fourteen (14) days after the Indemnifying Party’s receipt of an Indemnification Claim Notice. The assumption of the defence of a Third Party Claim by the Indemnifying Party shall not be construed as an acknowledgement that the Indemnifying Party is liable to indemnify any Indemnitee in respect of the Third Party Claim, nor shall it constitute a waiver by the Indemnifying Party of any defences it may assert against any Indemnified Party’s claim for indemnification.

(B) Control of the Defence

Upon the assumption of the defence of a Third Party Claim by the Indemnifying Party:

(1) the Indemnifying Party may appoint as lead counsel in the defence of the Third Party Claim any legal counsel selected by the Indemnifying Party which shall be reasonably acceptable to the Indemnified Party; and

25

(2) the Indemnifying Party shall not be liable to the Indemnified Party for any legal expenses subsequently incurred by such Indemnified Party in connection with the analysis, defence or settlement of the Third Party Claim. In the event that it is ultimately determined that the Indemnifying Party is not obligated to indemnify, defend or hold harmless an Indemnitee from and against the Third Party Claim, the Indemnified Party shall reimburse the Indemnifying Party for any and all costs and expenses (including lawyers’ fees and costs of suit and a solicitor client basis) incurred by the Indemnifying Party in its defence of the Third Party Claim with respect to such Indemnified Party or Indemnitee.

(C) Right to Participate in the Defence

Without limiting clauses 20.2(A) and 20.2(B) any Indemnitee shall be entitled to participate in, but not control, the defence of a Third Party Claim and to retain counsel of its choice for such purpose; provided, however, that such retention shall be at the Indemnitee’s own expense unless the Indemnifying Party has failed to assume the defence and retain counsel in accordance with clause 20.2(A) (in which case the Indemnified Party shall control the defence).

(D) Settlement

With respect to all Losses in connection with Third Party Claims, where the Indemnifying Party has assumed the defence of a Third Party Claim in accordance with clause 20.2(A), (i) the Indemnifying Party shall have authority to consent to the entry of any judgement, enter into any settlement or otherwise dispose of such Loss, provided that it obtains the prior written consent of the Indemnified Party which consent shall not be unreasonably withheld or delayed and (ii) no Indemnified Party or Indemnitee shall admit any liability with respect to, or settle, compromise or discharge, any such Third Party Claim without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld.

(E) Cooperation

If the Indemnifying Party chooses to defend or prosecute any Third Party Claim, at the Indemnifying Party’s request, the Indemnified Party shall, and shall cause each other Indemnitee to, reasonably cooperate in the defence or prosecution thereof and shall furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such cooperation shall include access during normal business hours by the Indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim, and making the Indemnified Party and its employees and agents available on a mutually convenient basis to provide additional information and explanation of any records or information provided, and the Indemnifying Party shall reimburse the Indemnified Party for all its related reasonable out-of-pocket expenses.

(B) for any loss that consists of loss of goodwill, reputation business, revenue, profit, saving or use of money (in each case whether direct or indirect); or

Any amendment or modification of this Agreement must be in writing and signed by authorised representatives of all Parties.

27.2 Entire Agreement

This Agreement and any documents or ancillary agreements, including the Test Service Agreement to be entered in to with the Dausset Lab referred to in it constitute the entire agreement between the Parties with respect to its subject matter. This Agreement supersedes all prior arrangements, undertakings, understandings or agreements, whether written or oral, with respect to its subject matter. Each Party confirms that in entering into this Agreement it is not relying on any statements, representations, warranties or covenants of any person (whether a Party or not) except as specifically set out in this Agreement including any such statements, representations, warranties or covenants made by a Party or its representatives prior to entering into this Agreement. Each Party waives all rights and remedies which, but for this clause, might otherwise be available to it in respect of any such representation, warranty, collateral contract or other assurance. All Schedules and Exhibits referred to in this

31

Agreement are intended to be and are hereby specifically incorporated into and made a part of this Agreement. This clause 27.2 shall not exclude or limit liability for fraud or fraudulent misrepresentation.

27.3 Audit Rights

XDx shall have the right, at its own expense, to access the books and records of Diaxonhit, its Affiliates and Sales Agents, as may be reasonably necessary to verify the accuracy of the gross and Net Sales in Sections 13.2 and 13.3. Such access shall be conducted no sooner than 15 Working Days’ prior written notice to and during ordinary business hours, will be conducted in a manner that is not disruptive to Diaxonhit’s operations, and shall not be more frequent than once per Sales Year. As it relates to the calculation of sales, if such independent certified public accountant’s report shows any underpayment by Diaxonhit, Diaxonhit shall remit to XDx within thirty (30) days after Diaxonhit’s receipt of such report, (a) the amount of such underpayment, and (b) if such underpayment exceeds five percent (5%) of the total amount owed for the period then being audited, the reasonable fees and expenses of any independent accountant performing the audit on behalf of XDx. Any audit or inspection conducted under this Agreement by XDx or its agents or contractors will be subject to the confidentiality provisions of this Agreement, and XDx will be responsible for compliance with such confidentiality provisions by such agents or contractors.

If any dispute arises under this Section 27.3 between the Parties relating to underpayments and the Parties cannot resolve such dispute within thirty (30) days of a written request by either Party to the other Party, the Parties shall hold a meeting, attended by the Chief Executive Officer or President of each party (or their respective designees), to attempt in good faith to negotiate a resolution of the dispute. If, within sixty (60) days after such meeting request, the Parties have not succeeded in negotiating a resolution of the dispute, either Party may pursue any other available remedy, including, upon prior written notice to the other Party, instituting legal action.

27.4 Expenses

Except as otherwise expressly provided in this Agreement, each Party shall pay the fees and expenses of its respective lawyers and other experts and all other expenses and costs incurred by such Party incidental to the negotiation, preparation, execution and delivery of this Agreement.

27.5 Force Majeure

No liability shall result from delay in performance or non-performance, in whole or in part, by either of the Parties to the extent that such delay or non-performance is caused by an event of Force Majeure. “Force Majeure” means an event that is beyond a non-performing Party’s reasonable control, including acts of God, strikes, lock-outs or other industrial/labour disputes, war, riot, civil commotion, terrorist act, malicious damage, epidemics, quarantines, fire, flood, storm or natural disaster. The Force Majeure Party shall, within five (5) days of the occurrence of the Force Majeure event, give written notice to the other Party stating the nature of the Force Majeure event, its anticipated duration and any action being taken to avoid or minimize its effect. Any suspension of performance shall be of no greater scope and of no longer duration than is reasonably required and the Force Majeure Party shall use best endeavours without being obligated to incur any material expenditure to remedy its inability to perform; provided, however, if the suspension of performance continues for sixty (60) days after the date of the occurrence and such failure to perform would constitute a material breach of this Agreement in the absence of such event of Force Majeure, the Parties shall meet and discuss in good faith any amendments to this Agreement to permit the other Party to exercise its rights under this Agreement. If the Parties are not able to agree on such amendments within thirty (30) days and if suspension of performance continues, such other Party may

32

The proceedings, including any outcome, shall be confidential.

(B) The Parties shall endeavour to resolve any Dispute by escalation to their management provided that this shall not prevent a Party taking any action under this clause 27.7.

(D) A breach by either Party of clause 18 or 23 will cause irreparable damage and the non-breaching Party will not be adequately compensated by monetary damages.

Schedule 6

Governance of Collaboration Committee

PURSUANT TO CLAUSE 6.5

1. Within 30 days from the Effective Date, the Parties will establish a Governance of Collaboration Committee (“the Collaboration Committee”) comprising two (2) voting representatives of each Party. Each Party may at any time appoint different representatives by prior written notice to the other Party. Additional representatives of a Party may attend meetings in a non-voting capacity. Each Party will designate one of its representatives as a co-chair of the Committee.

2. The Collaboration Committee will determine the commercialization strategy, monitor and manage the activities conducted pursuant to this Distribution and Licensing Agreement, and establish priorities and responsibilities regarding the key elements of the promotional, marketing and sales activities.

3. The Collaboration Committee will hold meetings at least once every quarter by teleconference or in person at such times and places as the co-chairs may determine, provided that they will meet in person at least once per year, alternating between the head offices of each Party. All other meetings need not be in person and may be by teleconference or other method. Each Party will bear its own costs associated with attending meetings.

4. Decisions of the Collaboration Committee will require unanimous consent to be binding. A voting representative of one Party may assign to a voting representative of the same Party the ability to give consent by proxy. If the Collaboration Committee is unable to reach unanimous consent on an issue, it will submit the issue to the Chief Executive Officer of each Party, who will confer; should these persons fail to agree, the Collaboration Committee will defer to the decision of a mediator or an independent expert, as appropriate to the nature of the dispute. Cost of the expertise will be shared equally between the Parties.

5. The Collaboration Committee will keep accurate minutes of its deliberations and will fmalize them for release to the Parties within ten (10) days of each meeting.

6. Each Party will promptly disclose to the other Party and to the Collaboration Committee in reasonable details all information that is necessary or reasonably useful for the other Party to perform its obligations under the Agreement. The Parties will provide the Collaboration Committee with reasonable access to records of the Parties, relating to the performance of the Agreement that the Collaboration Committee may reasonably require, except where such access is inconsistent with a Party’s duty of confidentiality to a third party.

7. Each Party will timely report to the other Party or to the Collaboration Committee significant events or information concerning the performance of this Agreement, including the Testing Services Agreement, Agents and Sub-Distributors.
