VI. DIVESTITURE TRUSTEE [34] If the Respondents have not fully complied with the obligation to Divest the Rolapitant Product Assets, as required by this Agreement, the Commissioner may appoint a Divestiture Trustee to Divest the Rolapitant Product Assets. The Divestiture Trustee will be a Person with experience and expertise in acquisitions and Divestitures. The selection of the Divestiture Trustee by the Commissioner shall be subject to the consent of Respondent Merck, which consent shall not be unreasonably withheld.

The Divestiture Trustee’s opinion of what constitutes favourable terms and conditions is subject to the Commissioner’s approval only.

(i) The Divestiture Trustee shall have the sole authority to determine, and the Respondents shall provide, all reasonable and ordinary commercial covenants, representations, warranties and indemnities for the purpose of completing the Divestiture of the Rolapitant Product Assets.

(j) The Divestiture Trustee shall serve, without bond or other security, at the cost and expense of the Respondents, and on such reasonable and customary terms and conditions as the Commissioner may set.

36

PUBLIC VERSION (k) The Respondents shall pay all reasonable invoices submitted by the Divestiture Trustee on a monthly basis. Any outstanding monies owed to the Divestiture Trustee by the Respondents shall be paid out of the proceeds of the Divestiture of the Rolapitant Product Assets.

(l) The Divestiture Trustee shall have the authority to employ, at the expense of the Respondents, such consultants, accountants, attorneys, investment bankers, business brokers, appraisers, and other representatives and assistants as are necessary to carry out the Divestiture Trustee’s duties and responsibilities.

(n) If the Divestiture Trustee ceases to act or fails to act diligently or otherwise in accordance with this Agreement or any agreement between the Commissioner and the Divestiture Trustee, the Commissioner may appoint a substitute Divestiture Trustee in the same manner as provided in this part VI for the initial Divestiture Trustee.

(o) The Divestiture Trustee shall have no obligation or authority to operate or maintain the Rolapitant Product Assets.

(p) The Divestiture Trustee shall report in writing to the Commissioner and the Respondents every sixty (60) days, and upon the Commissioner’s request within three (3) days, concerning the Divestiture Trustee’s efforts to complete the Divestiture of the Rolapitant Product Assets.

(s) If the Commissioner notifies the Divestiture Trustee that she has approved a proposed Divestiture of the Rolapitant Product Assets, the Divestiture Trustee shall forthwith notify the Respondents, in writing, of such proposed Divestiture of the Rolapitant Product Assets. Such notice shall include the identity of the Proposed Acquirer and the details of the proposed Divestiture of the Rolapitant Product Assets. Notwithstanding the foregoing, if the Divestiture Trustee receives bona fide offers from more than one Proposed Acquirer, and if the Commissioner determines to approve more than one such Proposed Acquirer, the Divestiture Trustee shall Divest the Rolapitant Product Assets to the Proposed Acquirer selected by the Respondents from among those approved by the Commissioner; provided further, however, that the Respondents shall select such Proposed Acquirer within five (5) days after receiving notification of the Commissioner’s approval.

(t) The Respondents may not object to or challenge the performance of the Divestiture Trustee’s duties under this Agreement or Divestiture of the Rolapitant Product Assets by the Divestiture Trustee on any grounds other than the Divestiture Trustee’s malfeasance, gross negligence or bad faith in executing its obligations hereunder. If the Respondents object to the terms and conditions of a Divestiture of the Rolapitant Product Assets that has been proposed by the Divestiture Trustee on the grounds of malfeasance, gross negligence or bad faith by the Divestiture Trustee, the Respondents or the Commissioner may apply to the Tribunal for directions, but in no event shall any such dispute serve to suspend the Divestiture Trustee Sale Period.

VII. FAILURE OF DIVESTITURE TRUSTEE SALE [36] If the Divestiture Trustee has not effected the Divestiture of the Rolapitant Product Assets at the end of the Divestiture Trustee Sale Period (including any extensions), or if the Commissioner is of the opinion that the Divestiture of the Rolapitant Product Assets will not likely be completed prior to the end of the Divestiture Trustee Sale Period, the Commissioner may apply to the Tribunal for such order as is necessary to effect the Divestiture of the Rolapitant Product Assets.

[37] The Respondents agree that the Tribunal has jurisdiction to grant such relief as is required to give effect to this Agreement and complete the Divestiture of the Rolapitant Product Assets.

VIII. CONFIDENTIAL BUSINESS INFORMATION [38] In addition to any other requirements and prohibitions relating to Confidential Business Information in this Agreement, the Respondents shall ensure that the Respondents’

38

PUBLIC VERSION counsel (including in-house counsel under appropriate confidentiality arrangements) shall not retain unredacted copies of documents or other materials provided to an Acquirer or access original documents provided to an Acquirer, except under circumstances where copies of documents are insufficient or otherwise unavailable, and for the following purposes:

[41] Respondents shall not modify or amend any of the terms of any Remedial Agreement without the prior approval of the Commissioner.

X. COMPLIANCE [42] Within five (5) days of the Acquisition, the Respondents shall submit to the Commissioner a letter certifying the date on which the Acquisition occurred.

[45] The Respondents shall notify the Commissioner at least thirty (30) days prior to: (a) any proposed dissolution of a Respondent; (b) any proposed acquisition, merger or consolidation of a Respondent; or (c) any other change in a Respondent including, but not limited to, assignment and the creation or dissolution of subsidiaries, if such dissolution, acquisition, merger, consolidation, or change might affect compliance obligations arising out of this Agreement.

[46] For purposes of determining or securing compliance with this Agreement, and subject to any legally recognized privilege, and upon written request and upon five (5) days notice to any Respondent, such Respondent shall, without restraint or interference, permit any duly authorized representative of the Commissioner:

(b) in respect of the obligations set forth hereunder relating to the Rolapitant Products and the Rolapitant Product Assets (specifically excluding the obligation set out in section 3(l)), until the Divestiture of the Rolapitant Product Assets is effected in accordance with this Agreement or further order of the Tribunal, and the related Product Manufacturing Technology has been fully transferred and delivered, or caused to be transferred and delivered, to the applicable Acquirer(s).

XIII. GENERAL [49] The Respondents agree to the immediate registration of this Agreement with the Tribunal.

[50] Nothing in this Agreement (including the recitals hereto) precludes Merck, Schering-Plough, or the Merged Entity from bringing a future application under section 106 of the Act (or a successor or equivalent provision under the Act) to vary or rescind this Agreement on the grounds that the circumstances that led to the making of this Agreement have changed and the other requirements of section 106(1) of the Act are satisfied. The Respondents agree that they shall not, in any such application, contest the Commissioner’s present conclusions that: (i) the Acquisition is likely to prevent or lessen competition substantially for the supply of NK-1 Receptor Antagonists for the prevention and treatment of CINV and PONV in humans, and that the divestiture of the Rolapitant Product Assets is necessary to ensure that such substantial lessening or prevention of competition will not result from the completion of the Acquisition; (ii) the Acquisition is likely to result in a substantial lessening or prevention of competition in certain animal health markets; and (iii) the exercise of the call right set out in the Call Option Agreement is likely to result in a substantial lessening or prevention of competition in certain animal health markets in Canada.

[51] This Agreement constitutes the entire agreement between the Commissioner and the Respondents and supersedes all prior agreements with respect to the subject matter hereof.

[52] This Agreement shall be governed by and interpreted in accordance with the laws of Ontario and the laws of Canada applicable therein.

42

PUBLIC VERSION [53] Computation of time periods contemplated by this Agreement shall be in accordance with the Interpretation Act, R.S.C. 1985, c. I-21. For the purpose of this Agreement, the definition of “holiday” in the Interpretation Act shall be deemed to include Saturday.

[54] Nothing in this Agreement abrogates the notification obligations set out in Part IX of the Act.

[55] In the event of a dispute regarding the interpretation or application of this Agreement, any of the Commissioner, Merck, Schering-Plough, or the Merged Entity may apply to the Tribunal for an order interpreting any of the provisions of this Agreement. In the event of any conflict or inconsistency between the English language version of this Agreement and the French language version of this Agreement, such conflict or inconsistency shall be resolved in favour of the English language version of this Agreement.
