Agreement made as of August 1, 2008 between UBS GLOBAL ASSET MANAGEMENT (AMERICAS) INC. (UBS Global Americas), a Delaware corporation, and XXXXXXX XXXXX ASSET MANAGEMENT, L.P. (Sub-Adviser), a Delaware Limited Partnership (the Agreement).

RECITALS

(1) UBS Global Americas has entered into a Management Agreement dated as of August 1, 2008, with UBS PACE Select Advisors Trust (Trust), an open-end management investment company registered under the Investment Company Act of 1940, as amended (1940 Act), and made applicable to UBS PACE Global Real Estate Securities Investments (Portfolio) via an Investment Management and Administration Fee Agreement dated as of November 30, 2006 (collectively, the Management Agreement); and

(2) UBS Global Americas is authorized to retain one or more sub-advisers to furnish certain investment advisory services to UBS Global Americas and the Portfolio; and

(3) UBS Global Americas desires to retain the Sub-Adviser to furnish certain investment advisory services to UBS Global Americas and the Portfolio or a designated portion of the assets (Segment) of the Portfolio; and

(4) The Sub-Adviser is willing to furnish such services;

NOW, THEREFORE, in consideration of the premises and mutual covenants herein contained, UBS Global Americas and the Sub-Adviser agree as follows:

1.Appointment.  UBS Global Americas hereby appoints the Sub-Adviser as an investment sub-adviser with respect to the Portfolio or Segment for the period and on the terms set forth in this Agreement. UBS Global Americas authorizes the Sub-Adviser to open accounts and execute documents (with standard indemnities) and representation letters in the name of, binding against and on behalf of the Segment for all reasonable and customary purposes necessary or desirable in the Sub-Advisers view to effectuate the Sub-Advisers activities under the Agreement.  The Sub-Adviser accepts that appointment and agrees to render the services herein set forth, for the compensation herein provided.

2. Duties as Sub-Adviser.

(a) Subject to the supervision and direction of the Trusts Board of Trustees (the Board) and review by UBS Global Americas, and any written guidelines adopted by the Board or UBS Global Americas provided in writing (receipt of which has been acknowledged by Sub-Adviser), the Sub-Adviser will provide a continuous investment program for the Portfolio or Segment, including investment research and discretionary management with respect to all securities and investments and cash equivalents in the Portfolio or Segment. The Sub-Adviser will determine from time to time what investments will be purchased, retained or sold by the Portfolio or Segment.  The Sub-Adviser will be responsible for placing purchase and sell orders for investments and for other related transactions for the Portfolio or Segment.  The Sub- Adviser understands that the Portfolios assets need to be managed so as to permit the Portfolio to qualify or to continue to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended (Code).  The Sub-Adviser will provide services under this Agreement in accordance with the Portfolios investment objective, policies and restrictions as stated in the Trusts currently effective registration statement under the 1940 Act, and any amendments or supplements thereto (Registration Statement).

(b) The Sub-Adviser agrees that it will not consult with any other sub-adviser (Other Sub-Adviser) for the Trust or Portfolio concerning any transaction by the Portfolio or Segment in securities or

other assets, including (i) the purchase by the Portfolio or Segment of a security issued by the Other Sub-Adviser, or an affiliate of the Other Sub-Adviser, to the Trust or Portfolio except as permitted by the 1940 Act or (ii) transactions by the Portfolio or Segment in any security for which the Other Sub-Adviser, or its affiliate, is the principal underwriter.  Sub-Adviser may communicate with other Sub-

Advisers under limited circumstances at the specific request of UBS Global Americas for compliance and other risk-management purposes to the extent allowed by law.

(c) The Sub-Adviser agrees that it will be responsible for voting proxies of issuers of securities held by the Portfolio or Segment.  The Sub-Adviser further agrees that it will adopt written proxy voting procedures that shall comply with the requirements of the 1940 Act and the Investment Advisers Act of 1940, as amended (Advisers Act), and that shall be acceptable to the Board.  The Sub-Adviser further agrees that it will provide the Board on or before August 1st of each year, or more frequently as the Board may reasonably request, with a written report of the proxies voted during the most recent 12-month period ending June 30, or such other period as the Board may designate, in a format that shall comply with the 1940 Act and that shall be acceptable to the Board.

Notwithstanding the above, UBS Global Americas or another service provider for the Trust, and not the Sub-Adviser, shall make any and all filings in connection with any securities litigation or class action lawsuits involving securities held or that were held in the Segment; provided, however, that GSAM is responsible for promptly forwarding to UBS Global Americas documents it receives regarding such matters that are specific to the Portfolio and providing reasonable assistance, if necessary, in making such claims Except as may be provided by applicable law or as otherwise provided herein, the Sub-Advisor shall not incur any liability to UBS Global Americas by reason of any exercise of, or failure to exercise, any such proxy voting discretion and shall not incur any liability for any failure arising from an act or omission of a person other than the Sub-Adviser or its agents.  UBS Global Americas understands that the Sub-Adviser establishes from time to time guidelines for the voting of proxies and may employ the services of a proxy voting service to exercise proxies in accordance with the Sub-Advisers guidelines

(d) The Sub-Adviser agrees that it will place orders with brokers in accordance with best execution policies, taking into account best price as an important factor in this decision, provided that, on behalf of the Portfolio or Segment, the Sub-Adviser may, in its discretion, use brokers that provide the Sub-Adviser with research, analysis, advice and similar services to execute portfolio transactions on behalf of the Portfolio or Segment, and the Sub-Adviser may pay to those brokers in return for brokerage and research services a higher commission than may be charged by other brokers, subject to the Sub-Advisers determination in good faith that such commission is reasonable in terms either of the particular transaction or of the overall responsibility of the Sub-Adviser to the Portfolio or Segment and its other clients and that the total commissions paid by the Portfolio or Segment will be reasonable in relation to the benefits to the Portfolio or Segment over the long term.  In no instance will portfolio securities be purchased from or sold to UBS Global Americas or the Sub-Adviser, or any affiliated person thereof, except in accordance with the federal securities laws and the rules and regulations thereunder.  The Sub-Adviser may aggregate sales and purchase orders with respect to the assets of the Portfolio or Segment with similar orders being made simultaneously for other accounts advised by the Sub-Adviser or its affiliates.  Whenever the Sub-Adviser simultaneously places orders to purchase or sell the same security on behalf of the Portfolio or Segment and one or more other accounts advised by the Sub-Adviser, the orders will be allocated as to price and amount among all such accounts in a manner believed to be equitable over time to each account.

UBS Global Americas recognizes that in some cases this procedure may adversely affect the results obtained for the Portfolio or Segment. Subject to the Sub-Advisers obligations to seek best execution, UBS Global Americas agrees that the Sub-Adviser, in its sole discretion, may place transactions on behalf of the Portfolio or Segment and the Trust with any broker-dealer deemed to be an affiliate of the Sub-Adviser (the Affiliated Broker-Dealers) so long as such transactions

are effected in conformity with the requirements (including any applicable exemptions and administrative interpretations set forth in Part II of the Sub-Advisers Form ADV Registration Statement on file with the Securities and Exchange Commission (Form ADV)) of Section 11(a)(1)(H) of the Securities Exchange Act of 1934.  In all such dealings, the Affiliated Broker-Dealers shall be authorized and entitled to retain any commissions, remuneration or profits which may be made in such transactions and shall not be liable to account for the same to UBS Global Americas, the Portfolio or the Trust.  UBS Global Americas further authorizes the Sub-Adviser and its Affiliated Broker-Dealers to execute agency cross transactions (the Cross Transactions) on behalf of the Portfolio and the Trust.  Cross Transactions are transactions which may be effected by the Affiliated Broker-Dealers acting for both the Portfolio or the Trust and the counterparty to the transaction.  Cross Transactions enable the Sub-Adviser to purchase or sell a block of securities for the Portfolio or the Trust at a set price and possibly avoid an unfavorable price movement that may be created through entrance into the market with such purchase or sale order.  As such, the Sub-Adviser believes that Cross Transactions can provide meaningful benefits for the Portfolio and the Trust and its clients generally.  UBS Global Americas, the Portfolio and the Trust should be aware, however, that in a Cross Transaction an Affiliated Broker-Dealer will be receiving commissions from both sides of the trade and, therefore, there is a potentially conflicting division of loyalties and responsibilities.  UBS Global Americas understands that its authority to the Sub-Adviser to execute agency Cross Transactions for the Portfolio is terminable at will without penalty, effective upon receipt by the Sub-Adviser of written notice from UBS Global Americas, and that the failure to terminate such authorization will result in its continuation.

(e) The Sub-Adviser will maintain all books and records required to be maintained, to the extent applicable, pursuant to Rule 31a-1(b)(2)(ii), (3), (5), (6), (7), (9) and (10) under the 1940 Act and the rules and regulations promulgated thereunder with respect to transactions by the Sub-Adviser on behalf of the Portfolio or Segment, and will furnish the Board and UBS Global Americas with such periodic and special reports as the Board or UBS Global Americas reasonably may request.  In compliance with the requirements of Rule 31a-3 under the 1940 Act, the Sub-Adviser hereby agrees that all records which it maintains for the Portfolio or Segment are the property of the Trust, agrees to preserve for the periods prescribed by Rule 31a-2 under the 1940 Act any records that it maintains for the Portfolio or Segment and that are required to be maintained by Rule 31a-1 under the 1940 Act, and further agrees to surrender promptly to the Trust any records which it maintains for the Portfolio or Segment upon request by the Trust.

(f) At such times as shall be reasonably requested by the Board or UBS Global Americas, the Sub-Adviser will provide the Board and UBS Global Americas with economic and investment analyses and reports as well as quarterly reports setting forth the performance of the Portfolio or Segment and make available to the Board and UBS Global Americas any economic, statistical and investment services that the Sub-Adviser normally makes available to its institutional or other customers.

(g) In accordance with procedures adopted by the Board, as amended from time to time, the Sub-Adviser is responsible for assisting the Board and UBS Global Americas in the fair valuation of all portfolio securities in the Portfolio or Segment and will use its reasonable efforts to arrange for the provision of a price or prices from one or more parties independent of the Sub-Adviser for each portfolio security for which the custodian does not obtain prices in the ordinary course of business from an automated pricing service.

3. Further Duties.  In all matters relating to the performance of this Agreement, the Sub-Adviser will seek to act in conformity with the Trusts Trust Instrument, By-Laws and Registration Statement and with the written instructions and written directions of the Board and UBS Global Americas, each as provided to and whose receipt is acknowledged by the Sub-Adviser, and will comply with the requirements of the 1940 Act, and the Advisers Act, and the rules under each, the Code, and all other federal and state laws and regulations applicable to the Trust and the

Portfolio. UBS Global Americas agrees to provide to the Sub-Adviser copies of the Trusts Trust Instrument, By-Laws, Registration Statement, written instructions and directions of the Board and UBS Global Americas, and any amendments or supplements to any of these materials as soon as practicable after such materials become available; and further agrees to identify to the Sub-Adviser in writing any broker-dealers that are affiliated with UBS Global Americas (other than UBS Financial Services Inc.).

4. Expenses.  During the term of this Agreement, the Sub-Adviser will bear all expenses incurred by it in connection with its services under this Agreement. The Sub-Adviser shall not be responsible for any expenses incurred by the Trust, the Portfolio or UBS Global Americas.

5. Compensation.

(a) For the services provided and the expenses assumed by the Sub-Adviser pursuant to this Agreement, UBS Global Americas, not the Portfolio, will pay to the Sub-Adviser a fee, computed daily and payable monthly, at an annual rate of 0.42% up to $50 million and 0.40% on assets in excess of $50 million of the average daily net assets of the Portfolio or Segment allocated to its management (computed in the manner specified in the Management Agreement), and will provide the Sub-Adviser with a schedule showing the manner in which the fee was computed.  If the Sub-Adviser is managing a Segment, its fees will be based on the value of the assets of the Portfolio within the Sub-Advisers Segment.

(b) The fee shall be accrued daily and payable monthly to the Sub-Adviser on or before the last business day of the next succeeding calendar month.

(c) If this Agreement becomes effective or terminates before the end of any month, the fee for the period from the effective date to the end of the month or from the beginning of such month to the date of termination, as the case may be, shall be pro-rated according to the proportion which such period bears to the full month in that such effectiveness or termination occurs.

6. Limitation of Liability.

(a) The Sub-Adviser shall not be liable for any error of judgment or mistake of law or for any loss suffered by the Portfolio, the Trust or its shareholders or by UBS Global Americas in connection with the matters to which this Agreement relates, except a loss resulting from willful misfeasance, bad faith or gross negligence on its part in the performance of its duties or from reckless disregard by it of its obligations and duties under this Agreement.

(b) In no event will the Sub-Adviser have any responsibility for any other portfolio of the Trust, for any portion of the Portfolio not managed by the Sub-Adviser or for the acts or omissions of any Other Sub-Adviser to the Trust or Portfolio.  In particular, in the event the Sub-Adviser shall manage only a Segment of the Portfolio, the Sub-Adviser shall have no responsibility for the Portfolios being in violation of any applicable law or regulation or investment policy or restriction applicable to the Portfolio as a whole or for the Portfolios failing to qualify as a regulated investment company under the Code, if the securities and other holdings of the Segment of the Portfolio managed by the Sub-Adviser are such that such Segment would not be in such violation or fail to so qualify if such Segment were deemed a separate series of the Trust or a separate regulated investment company under the Code.  The Sub-Adviser shall have no responsibility to monitor compliance with respect to other portions of the Portfolio that are not under the Sub-Advisers management, and the Sub-Adviser shall have no responsibility to monitor compliance with limitations and restrictions specifically applicable to the Portfolio or Segment unless such limitations or restrictions are provided to and whose receipt is acknowledged by the Sub-Adviser in writing or which generally apply to an advisor to a registered investment company or a registered investment company under applicable law.  Nothing in this section shall be deemed a limitation or waiver of any obligation or duty that may not by law be limited or waived.
