FORM OF PLACEMENT AGENCY AGREEMENT WITH BLACKROCK INVESTMENTS INC

AGREEMENT made as of the 1^st day of October 2008, between QUANTITATIVE MASTER SERIES LLC, a Delaware limited liability company (the “Company”), on behalf of its series listed on Appendix A attached hereto, as such Appendix may be amended from time to time, (the “Series”), and BLACKROCK INVESTMENTS, INC., a Delaware corporation (the “Placement Agent”). The obligations of each Series hereunder shall be limited to the assets of that Series, shall be separate from the obligations of each other Series, and no Series shall be liable for the obligations of any other Series.

WHEREAS, the Company has filed a registration statement (the “Registration Statement”) pursuant to Section 8(b) of the Investment Company Act of 1940, as amended (the “Investment Company Act”); and

WHEREAS, the Directors of the Company (the “Directors”) are authorized to establish separate series relating to separate portfolios of securities, each of which may offer interests in the Series (“Interests”); and

WHEREAS, the Directors have established and designated the Series as series of the Company; and

WHEREAS, the Company and the Placement Agent wish to enter into an agreement with each other with respect to the distribution of Interests in the Series.

(a) The Company hereby appoints the Placement Agent as placement agent in connection with the distribution of the Interests.

(b) The Placement Agent understands that: (i) The Interests are not being registered under the Securities Act of 1933, as amended (the “Securities Act”); (ii) Such Interests are to be issued solely in private placement transactions that do not involve any “public offering” within the meaning of Section 4(2) of the Securities Act; (iii) Investments in the Series may be made only by a limited number of institutional investors, including investment companies, common or commingled trust funds, group trusts and certain other “accredited investors” within the meaning of Regulation D under the Securities Act; and (iv) The Registration Statement is not intended to constitute an offer to sell, or the solicitation of an offer to buy, any beneficial interests in the Series.

(c) In carrying out its duties hereunder, the Placement Agent agrees that it will act in a manner consistent with the foregoing and, unless otherwise instructed by the Company in writing, will not take any actions which would cause the Company to make a “public offering” within the meaning of Section 4(2) of the Securities Act.

Section 2. Exclusive Nature of Duties. The Placement Agent shall be the exclusive representative of the Series to act as placement agent in respect of the distribution of the Interests, except that:

(a) The Company may, with respect to any Series, upon written notice to the Placement Agent, from time to time designate other placement agents with respect to areas other than the United States as to which the Placement Agent may have expressly waived in writing its right to act as such. If such designation is deemed exclusive, the right of the Placement Agent under this Agreement in respect of such areas so designated shall terminate, but this Agreement shall remain otherwise in full force and effect until terminated in accordance with the other provisions hereof.

(b) The exclusive right granted to the Placement Agent hereunder shall not apply to Interests issued in connection with the merger or consolidation of any other investment company or personal holding company with a Series or the acquisition by purchase or otherwise of all (or substantially all) the assets or the outstanding shares of any such company by a Series.

(c) Such exclusive right also shall not apply to Interests issued by a Series pursuant to reinvestment of dividends or capital gains distributions.

(d) Such exclusive right also shall not apply to Interests issued by a Series pursuant to any conversion, exchange or reinstatement privilege afforded redeeming shareholders or to any other Interests as shall be agreed between the Company and the Placement Agent from time to time.

(a) The Company shall furnish to the Placement Agent copies of all information, financial statements and other papers which the Placement Agent may reasonably request for use in connection with its duties hereunder, and this shall include, upon request by the Placement Agent, one certified copy of all financial statements prepared for the Company by independent public accountants.

(b) Consistent with Section 1 hereof, the Company shall use its best efforts to qualify and maintain the qualification of the Interests for sale under the securities laws of such jurisdictions as the Placement Agent and the Company may approve. Any such qualification may be withheld, terminated or withdrawn by the Company at any time in its discretion. The expense of qualification and maintenance of qualification shall be borne by the Company. The Placement Agent shall furnish such information and other material relating to its affairs and activities as may be required by the Company in connection with such qualification.

(c) The Company will furnish to the Placement Agent, in reasonable quantities upon request by the Placement Agent, copies of annual and interim reports of each Series.

(a) The Placement Agent shall devote reasonable time and effort to its duties hereunder. The services of the Placement Agent to the Company hereunder are not to be deemed exclusive and nothing herein contained shall prevent the Placement Agent from entering into like arrangements with other investment companies so long as the performance of its obligations hereunder is not impaired thereby.

(b) In performing its duties hereunder, the Placement Agent shall use its best efforts in all respects to duly conform with the requirements of all applicable laws relating to the sale of securities. Neither the Placement Agent nor any other person is authorized by the Company to give any information or to make any representations, other than those contained in the Company’s registration statement or any supplemental literature specifically approved by the Company.

(a) The Company shall bear all costs and expenses of the Series, including fees and disbursements of its counsel and auditors, in connection with the preparation and filing of any required registration statements under the Investment Company Act, and all amendments and supplements thereto, and preparing and mailing annual and interim reports and proxy materials to shareholders (including but not limited to the expense of setting in type any such registration statements, or interim reports or proxy materials).

(b) The Company shall bear any cost and expenses of qualification of the Interests for sale pursuant to this Agreement and, if necessary or advisable in connection therewith, of qualifying the Company as a broker or dealer in such states of the United States or other jurisdictions as shall be selected by the Company and the Placement Agent pursuant to Section 3 hereof and the cost and expenses payable to each such state for continuing qualification therein until the Company decides to discontinue such qualification pursuant to Section 3 hereof.

(a) The Company shall indemnify and hold harmless the Placement Agent and each person, if any, who controls the Placement Agent against any loss, liability, claim, damage or expense (including the reasonable cost of investigating or defending any alleged loss, liability, claim, damage or expense and reasonable counsel fees incurred in connection therewith), as incurred, arising by reason of any person acquiring any Interests, which may be based upon the Securities Act, or on any other statute or at common law, on the ground that any registration statement or other offering materials, as from time to time amended and supplemented, or an annual or interim report to interestholders of the Series, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading, unless such statement or omission was made in

reliance upon, and in conformity with, information furnished to the Company in connection therewith by or on behalf of the Placement Agent; provided, however, that in no case (i) is the indemnity of the Company in favor of the Placement Agent and any such controlling persons to be deemed to protect such Placement Agent or any such controlling persons thereof against any liability to the Company (or any Series) or its interestholders to which the Placement Agent or any such controlling persons would otherwise be subject by reason of willful misfeasance, bad faith or gross negligence in the performance of their duties or by reason of the reckless disregard of their obligations and duties under this Agreement; or (ii) is the Company (or any Series) to be liable under its indemnity agreement contained in this paragraph with respect to any claim made against the Placement Agent or any such controlling persons, unless the Placement Agent or such controlling persons, as the case may be, shall have notified the Company in writing within a reasonable time after the summons or other first legal process giving information of the nature of the claim shall have been served upon the Placement Agent or such controlling persons (or after the Placement Agent or such controlling persons shall have received notice of such service on any designated agent), but failure to notify the Company of any such claim shall not relieve it from any liability which it may have to the person against whom such action is brought otherwise than on account of its indemnity agreement contained in this paragraph. The Company will be entitled to participate at its own expense in the defense or, if it so elects, to assume the defense of any suit brought to enforce any such liability, but if the Company elects to assume the defense, such defense shall be conducted by counsel chosen by it and satisfactory to the Placement Agent or such controlling person or persons, defendant or defendants in the suit. In the event the Company elects to assume the defense of any such suit and retain such counsel, the Placement Agent or such controlling person or persons, defendant or defendants in the suit shall bear the fees and expenses, as incurred, of any additional counsel retained by them, but in case the Company does not elect to assume the defense of any such suit, it will reimburse the Placement Agent or such controlling person or persons, defendant or defendants in the suit, for the reasonable fees and expenses, as incurred, of any counsel retained by them. The Company shall promptly notify the Placement Agent of the commencement of any litigation or proceedings against it or any of its officers or Directors in connection with the issuance or sale of any of the Interests.

(b) The Placement Agent shall indemnify and hold harmless the Company and each of its Directors and officers and each person, if any, who controls the Company against any loss, liability, claim, damage or expense, as incurred, described in the foregoing indemnity contained in subsection (a) of this Section, but only with respect to statements or omissions made in reliance upon, and in conformity with, information furnished to the Company in writing by or on behalf of the Placement Agent for use in connection with the registration statement or other offering materials, as from time to time amended, or the annual or interim reports to shareholders. In case any action shall be brought against the Company or any person so indemnified, in respect of which indemnity may be sought against the Placement Agent, the Placement Agent shall have the rights and duties given to the Company, and the Company and each person so indemnified shall have the rights and duties given to the Placement Agent by the provisions of subsection (a) of this Section 6.

Section 7. Duration and Termination of this Agreement. This Agreement shall become effective as of the date first above written and shall remain in force for two years

thereafter and thereafter continue from year to year, but only so long as such continuance is specifically approved at least annually (i) with respect to one or more of the Series, by the Directors or with respect to a Series, by the vote of a majority of the outstanding voting securities of such Series and (ii) by the vote of a majority of those Directors who are not parties to this Agreement or interested persons of any such party cast in person (if such an in person meeting is required by applicable law) at a meeting called for the purpose of voting on such approval.

This Agreement may be terminated at any time, without the payment of any penalty with respect to one or more of the Series, by the Directors or with respect to a Series, by vote of a majority of the outstanding voting securities of such Series, or by the Placement Agent, on sixty days’ written notice to the other party. This Agreement shall automatically terminate in the event of its assignment.

The terms “vote of a majority of the outstanding voting securities”, “assignment”, “affiliated person” and “interested person”, when used in this Agreement, shall have the respective meanings specified in the Investment Company Act.

This Agreement may be amended by the parties only if such amendment is specifically approved (i) (a) with respect to all Series, by the Directors or by the vote of a majority of outstanding voting securities of each Series, or (b) with respect to any one Series, by the Directors or the vote of a majority of outstanding voting securities of such Series, and (ii) by the vote of a majority of those Directors who are not parties to this Agreement or interested persons of any such party cast in person (if such an in person meeting is required by applicable law) at a meeting called for the purpose of voting on such approval.

Section 9. Governing Law.
