                               W I T N E S S E T H

     WHEREAS, the Adviser serves as investment manager to PIONEER CULLEN [] (the
"Fund"), pursuant to a Management Agreement between the Fund and the Adviser
dated [] (the "Management Agreement");

     WHEREAS, pursuant to authority granted to the Adviser by the Board of
Trustees of the Fund (the "Board") and pursuant to the provisions of the
Management Agreement, the Adviser has selected the Sub-Adviser to act as
investment sub-adviser of the Fund and to provide certain other services, as
more fully set forth below, and to perform such services under the terms and
conditions hereinafter set forth;

     NOW, THEREFORE, in consideration of the mutual covenants and benefits set
forth herein, the Adviser and the Sub-Adviser do hereby agree as follows:

     1. The Sub-Adviser's Services.

          (a) Investment Services. The Sub-Adviser shall act as investment
     sub-adviser with respect to the Fund. In such capacity, the Sub-Adviser
     shall, subject to the supervision of the Adviser and the Board, regularly
     provide the Fund with investment research, advice and supervision and shall
     furnish continuously an investment program for the Fund, consistent with
     the investment objectives and policies of the Fund. The Sub-Adviser shall
     determine, from time to time, what securities shall be purchased for the
     Fund, what securities shall be held or sold by the Fund and what portion of
     the Fund's assets shall be held uninvested in cash, subject always to the
     provisions of the Fund's Certificate of Trust, Agreement and Declaration of
     Trust, By-Laws and its registration statement on Form N-1A (the
     "Registration Statement") under the Investment Company Act of 1940, as
     amended (the "1940 Act"), and under the Securities Act of 1933, as amended
     (the "1933 Act"), covering the Fund's shares, as filed with the U.S.
     Securities and Exchange Commission (the "Commission"), and to the
     investment objectives, policies and restrictions of the Fund, as each of
     the same shall be from time to time in effect. To carry out such
     obligations, the Sub-Adviser shall exercise full discretion and act for the
     Fund in the same manner and with the same force and effect as the Fund
     itself might or could do with respect to purchases, sales or other
     transactions, as well as with respect to all other such things necessary or
     incidental to the furtherance or conduct of such purchases, sales or other
     transactions. Notwithstanding the foregoing, the Sub-Adviser shall, upon
     written instructions from the Adviser, effect such portfolio transactions
     for the Fund as the Adviser may from time to time direct. The Sub-Adviser




     shall have no responsibility hereunder or otherwise with respect to
     any such transaction other than to effect such transaction in accordance
     with the Adviser's instructions, including without limiting the foregoing,
     any responsibility under sub-paragraph (b) of this Paragraph 1. No
     reference in this Agreement to the Sub-Adviser having full discretionary
     authority over the Fund's investments shall in any way limit the right of
     the Adviser, in its sole discretion, to establish or revise policies in
     connection with the management of the Fund's assets or, subject to the
     foregoing, to otherwise exercise its right to control the overall
     management of the Fund's assets.

          (b) Compliance. The Sub-Adviser agrees to comply with the requirements
     of the 1940 Act, the Investment Advisers Act of 1940 (the "Advisers Act"),
     the 1933 Act, the Securities Exchange Act of 1934, as amended (the "1934
     Act"), the Commodity Exchange Act and the respective rules and regulations
     thereunder, as applicable, as well as with all other applicable federal and
     state laws, rules, regulations and case law that relate to the services and
     relationships described hereunder and to the conduct of its business as a
     registered investment adviser. The Sub-Adviser also agrees to comply with
     the objectives, policies and restrictions set forth in the Registration
     Statement, as amended or supplemented, of the Fund, and with any policies,
     guidelines, instructions and procedures approved by the Board or the
     Adviser and provided to the Sub-Adviser. In selecting portfolio securities
     for the Fund and performing the Sub-Adviser's obligations hereunder, the
     Sub-Adviser shall conduct its activities in such a manner as to cause the
     Fund to comply with the requirements of Subchapter M of the Internal
     Revenue Code of 1986, as amended (the "Code"), as applicable, for
     qualification as a regulated investment company, subject to subparagraph
     (a) of this Section 1. The Sub-Adviser shall maintain compliance procedures
     that it reasonably believes are adequate to ensure its compliance with the
     foregoing. The Sub-Adviser shall also maintain compliance procedures that
     it reasonably believes are adequate to ensure its compliance with the
     Advisers Act. No supervisory activity undertaken by the Adviser shall limit
     the Sub-Adviser's full responsibility for any of the foregoing.

          (c) Proxy Voting. The Board has the authority to determine how proxies
     with respect to securities that are held by the Fund shall be voted, and
     the Board has initially determined to delegate the authority and
     responsibility to vote proxies for the Fund securities to the Adviser. So
     long as proxy voting authority for the Fund has been delegated to the
     Adviser, the Sub-Adviser shall provide such assistance to the Adviser with
     respect to the voting of proxies for the Fund as the Adviser may from time
     to time reasonably request, and the Sub-Adviser shall promptly forward to
     the Adviser any information or documents upon receipt necessary for the
     Adviser to exercise its proxy voting responsibilities. The Sub-Adviser
     shall not vote proxies with respect to the securities held by the Fund
     unless and until the Board or the Adviser delegates such authority and
     responsibility to the Sub-Adviser or otherwise instructs the Sub-Adviser to
     do so in writing, whereupon the Sub-Adviser shall carry out such
     responsibility in accordance with any instructions that the Board or the
     Adviser shall provide from time to time and shall provide such reports and
     keep such records relating to proxy voting as the Board or the Adviser may
     reasonably request or as may be necessary for the Fund to comply with the
     1940 Act and other applicable law. Any such delegation of proxy voting

                                       2



     responsibility to the Sub-Adviser may be revoked or modified by the
     Board or the Adviser at any time.

          (d) Recordkeeping. The Sub-Adviser shall not be responsible for the
     provision of administrative, bookkeeping or accounting services to the
     Fund, except as otherwise provided herein or as may be reasonably necessary
     for the Sub-Adviser to supply to the Adviser, the Fund or the Board the
     information required to be supplied under this Agreement.

          The Sub-Adviser shall maintain separate books and detailed records of
     all matters pertaining to the Fund's assets advised by the Sub-Adviser
     required by sub-paragraphs (b)(5), (6), (7), (9), (10) and (11) and
     paragraph (f) of Rule 31a-1 under the 1940 Act (other than those records
     being maintained by the Adviser, custodian or transfer agent appointed by
     the Fund) relating to Fund transactions hereunder, and shall preserve such
     records for the periods and in a manner prescribed therefore by Rule 31a-2
     under the 1940 Act (the "Fund's Books and Records"). The Fund's Books and
     Records shall be available to the Adviser and the Board at any time upon
     request with reasonable notice, copies of which shall be delivered to the
     Fund upon the termination of this Agreement pursuant to Paragraph 11 of
     this Agreement and shall be available for telecopying without delay during
     any day the Fund is open for business.

          (e) Holdings Information and Pricing. The Sub-Adviser shall keep the
     Fund and the Adviser informed of developments materially affecting the
     Fund's holdings, and shall, on its own initiative, furnish the Fund and the
     Adviser from time to time with whatever information the Sub-Adviser
     believes is appropriate for this purpose and is readily available to the
     Sub-Adviser. The Sub-Adviser agrees to immediately notify the Adviser if
     the Sub-Adviser believes that the market quotations are not readily
     available for any security held by the Fund or if the market price does not
     reflect the security's fair value. In such instances, the Sub-Adviser shall
     provide assistance to the Adviser and/or the Fund's pricing agent in making
     determinations of the fair value of such portfolio securities in accordance
     with the Fund's written valuation procedures..

          (f) Cooperation with Agents of the Adviser and the Fund. The
     Sub-Adviser agrees to cooperate with and provide reasonable assistance to
     the Adviser, the Fund, the Fund's custodian and foreign sub-custodians, the
     Fund's pricing agents and all other agents and representatives of the Fund
     and the Adviser, provide them with such information with respect to
     securities held by the Fund as they may reasonably request from time to
     time in the performance of their obligations, provide prompt responses to
     reasonable requests made by such persons and establish appropriate
     interfaces with each so as to promote the efficient exchange of information
     and compliance with applicable laws and regulations.

     2. Code of Ethics. The Sub-Adviser has adopted a written code of ethics
that it reasonably believes complies with the requirements of Rule 17j-1 under
the 1940 Act, which it will provide to the Adviser and the Fund. The Sub-Adviser
shall comply and shall require its employees to comply in all respects with the
Sub-Adviser's Code of Ethics, as in effect from time to time. Upon request, the
Sub-Adviser shall provide the Fund with a (i) a copy of the Sub-

                                       3



Adviser's current Code of Ethics, as in effect from time to time, and (ii)
certification that it has adopted procedures reasonably designed to prevent
Access Persons from engaging in any conduct prohibited by the Sub-Adviser's Code
of Ethics. Annually, the Sub-Adviser shall furnish a written report, which
complies with the requirements of Rule 17j-1, concerning the Sub-Adviser's Code
of Ethics to the Funds and the Adviser. The Sub-Adviser shall respond to
requests for information from the Adviser as to violations of the Code and any
sanctions imposed by the Sub-Adviser in connection with such violations. The
Sub-Adviser shall immediately notify the Adviser of any material violation of
the Code, whether or not such violation relates to any security held by the
Fund.

     3. Information and Reporting. The Sub-Adviser shall promptly report to the
Adviser any material developments regarding portfolio securities of the Fund
that may of which the Sub-Adviser has knowledge, that materially affect the
Fund. In this regard, the Sub-Adviser shall provide the Fund, the Adviser, and
their respective officers with such periodic reports concerning the obligations
the Sub-Adviser has assumed under this Agreement as the Fund and the Adviser may
from time to time reasonably request. The Sub-Adviser shall promptly notify the
Adviser of any financial condition that is likely to impair the Sub-Adviser's
ability to perform its obligations under this Agreement.

          (a) Notification of Breach / Compliance Reports. The Sub-Adviser shall
     notify the Adviser immediately upon its detection of (i) any failure on its
     part to manage the Fund in accordance with this Agreement; or (ii) any
     breach by the Sub-Adviser of any of the policies, guidelines or procedures
     of the Fund or the Adviser as provided in writing to the Sub-Adviser or of
     the Sub-Adviser insofar as they relate or reasonably would affect the
     performance of the Sub-Adviser's responsibilities hereunder. In addition,
     the Sub-Adviser shall provide a quarterly certification that is the
     Sub-Adviser has managed the Fund in accordance with the provisions of this
     Agreement in the form provided by the Adviser from time to time. The
     Sub-Adviser acknowledges and agrees that the Adviser may, in its
     discretion, provide such quarterly compliance certifications to the Board.
     The Sub-Adviser agrees to correct any such failure on its part promptly and
     to take any action that the Adviser may reasonably request in connection
     with any such breach. The Sub-Adviser shall also provide the officers of
     the Fund with supporting certifications in connection with such
     certifications of the Fund's financial statements and disclosure controls
     pursuant to the Sarbanes-Oxley Act. The Sub-Adviser, to the extent
     permissible, will promptly notify the Adviser if (i) the Sub-Adviser is
     served or otherwise receives notice of any action, suit, proceeding,
     inquiry or investigation, at law or in equity, before or by any court,
     public board, or body, involving the affairs of the Fund (excluding class
     action suits in which the Fund is a member of the plaintiff class by reason
     of the Fund's ownership of shares in the defendant) or the compliance by
     the Sub-Adviser with federal or state securities laws or (ii) the
     controlling stockholder changes or there otherwise is an actual change in
     control (whether through sale of all or substantially all the assets of the
     Sub-Adviser or a material change in management of the Sub-Adviser) or an
     "assignment" (as defined in the 1940 Act) has or is proposed to occur.

          (b) Inspection. Upon request, with at least 24 hours advance notice,
     the Sub-Adviser subject to privacy and other laws agrees to make its
     records and premises (including the availability of the Sub-Adviser's
     employees for interviews) to the extent

                                       4



     that they relate to the conduct of services provided by the Sub-Adviser to
     the Fund or the Sub-Adviser's conduct of its business as an investment
     adviser available for compliance audits by the Adviser or the Fund's
     employees, accountants or counsel; in this regard, the Fund and the Adviser
     acknowledge that the Sub-Adviser shall have no obligations to make
     available proprietary information unrelated to the services provided to the
     Fund or any information related to other clients of the Sub-Adviser, except
     to the extent necessary for the Adviser to confirm the absence of any
     conflict of interest and compliance with any laws, rules or regulations in
     the management of the Fund.

          (c) Board and Filings Information. The Sub-Adviser will provide the
     Adviser with any information reasonably requested regarding its management
     of the Fund required for any meeting of the Board, or for any shareholder
     report, amended registration statement, proxy statement, or prospectus
     supplement to be filed by the Fund with the Commission. The Sub-Adviser
     will make its officers and employees available to meet with the Board from
     time to time on reasonable notice to review the investments of the Fund in
     light of current and prospective economic and market conditions and shall
     furnish to the Board such information as may reasonably be necessary in
     order for the Board to evaluate this Agreement or any proposed amendments
     thereto.

          (d) Transaction Information. The Sub-Adviser shall furnish to the
     Adviser such information concerning portfolio transactions as may be
     necessary to enable the Adviser to perform such compliance testing on the
     Fund and the Sub-Adviser's services as the Adviser may, in its sole
     discretion, determine to be appropriate. The provision of such information
     by the Sub-Adviser in no way relieves the Sub-Adviser of its own compliance
     responsibilities for the Fund hereunder, as and to the extent herein
     provided.

     4. Brokerage.

          (a) Principal and Agency Transactions. In connection with purchases or
     sales of securities for the account of the Fund, neither the Sub-Adviser
     nor any of its directors, officers, employees or affiliated persons will
     act as a principal or agent or receive any commission except as permitted
     by the 1940 Act.

          (b) Placement of Orders. Except as set forth in sub-paragraph (e) of
     this Section 4 the Sub-Adviser shall arrange for the placing of all orders
     for the purchase and sale of securities for the Fund's account with brokers
     or dealers selected by the Sub-Adviser. In its selection of such brokers or
     dealers and the placing of such orders, the Sub-Adviser is directed at all
     times to seek for the Fund the most favorable execution and net price
     available under the circumstances except as described herein. It is also
     understood that it is desirable for the Fund that the Sub-Adviser have
     access to supplemental investment and market research and security and
     economic analyses provided by brokers who may execute brokerage
     transactions at a higher cost to the Fund than may result when allocating
     brokerage to other brokers, as consistent with Section 28(e) of the 1934
     Act and any Commission staff interpretations thereof. Therefore, the
     Sub-Adviser is authorized to place orders for the purchase and sale of
     securities for the Fund with such brokers, subject to guidelines
     established by the Adviser and provided in writing to the Sub-Adviser by
     the Adviser or the Board from time to time with respect to

                                       5



     the extent and continuation of this practice. It is understood that the
     services provided by such brokers may be useful to the Sub-Adviser in
     connection with its or its affiliates' services to other clients. In
     addition, subject to the Sub-Adviser's obligation to seek the most
     favorable execution and net price available under the circumstances, the
     Sub-Adviser to the extent legally permissible, may consider the sale of the
     Fund's shares in selecting brokers and dealers. The Sub-Adviser and not the
     Fund or the Adviser shall be liable for any losses or costs resulting from
     the Sub-Adviser's errors in placing trades on behalf of the Fund.

          (c) Aggregated Transactions. On occasions when the Sub-Adviser deems
     the purchase or sale of a security to be in the best interest of the Fund
     as well as other clients of the Sub-Adviser, the Sub-Adviser may, to the
     extent permitted by applicable law and regulations, aggregate the order for
     securities to be sold or purchased in order to obtain the most favorable
     execution and lower brokerage commissions, if any. In such event,
     allocation of the securities or futures contracts so purchased or sold, as
     well as the expenses incurred in the transaction, will be made by the
     Sub-Adviser in the manner the Sub-Adviser considers to be the most
     equitable and consistent with its fiduciary obligations to the Fund and to
     such other clients.

          (d) Affiliated Brokers. The Sub-Adviser or any of its affiliates may
     act as broker in connection with the purchase or sale of securities or
     other investments for the Fund, subject to: (a) the requirement that the
     Sub-Adviser seek to obtain most favorable execution and most favorable net
     price available under the circumstances within the policy guidelines
     determined by the Board and set forth in the Fund's current prospectus and
     SAI; (b) the provisions of the Investment Company Act, the Advisers Act and
     the rules of the Commission under such Acts; (c) the provisions of the 1934
     Act; and (d) other provisions of applicable law. These brokerage services
     are not within the scope of the duties of the Sub-Adviser under this
     Agreement. Subject to the requirements of applicable law and any procedures
     adopted by the Board, the Sub-Adviser or its affiliates may receive
     brokerage commissions, fees or other remuneration from the Fund for these
     services in addition to the Sub-Adviser's fees for services under this
     Agreement.

          (e) Alternative Trading Arrangements. From time to time the
     Sub-Adviser and the Adviser may agree that the Sub-Advisor will place some
     or all of the trades for the Fund through the Adviser's trading desk. In
     such event, the Adviser shall have complete authority to determine the
     brokers or dealers through which any trade by the Fund is placed through
     the Advisers trading desk and as to the timing and manner of the execution
     of any such trade, although the Sub-Adviser may give guidance. In such
     event, the Adviser shall be responsible for obtaining most favorable
     execution and best net price available under the circumstances for the Fund
     on trades placed by the Adviser and the Sub-Adviser shall remain
     responsible only for the accurate placement of orders on behalf of the Fund
     into the Adviser's trading system and confirming the appropriate settlement
     of such transactions in accordance with the orders placed.

     5. Custody. Nothing in this Agreement shall permit the Sub-Adviser to take
or receive physical possession of cash, securities or other investments of the
Fund.

                                       6



     6. Allocation of Charges and Expenses. The Sub-Adviser will bear its own
costs of providing its services hereunder. Other than as herein specifically
indicated, the Sub-Adviser shall not be responsible for the Fund's or the
Adviser's expenses, including brokerage and other expenses incurred in placing
orders for the purchase and sale of securities and other investment instruments.
Specifically, the Sub-Adviser will not be responsible for expenses of the Fund
or the Adviser, as the case may be, including, but not limited to, the
following: (i) charges and expenses for accounting, pricing and appraisal
services and related overhead, including, to the extent such services are
performed by personnel of the Sub-Adviser or its affiliates, office space and
facilities, and personnel compensation, training and benefits; (ii) the charges
and expenses of auditors; (iii) the charges and expenses of any custodian,
transfer agent, plan agent, dividend disbursing agent and registrar appointed by
the Fund; (iv) underwriting commissions and issue and transfer taxes chargeable
to the Fund in connection with securities transactions to which the Fund is a
party; (v) insurance premiums, interest charges, dues and fees for membership in
trade associations and all taxes and corporate fees payable by the Fund to
federal, state or other governmental agencies; (vi) fees and expenses involved
in registering and maintaining registrations of the Fund's shares with federal
regulatory agencies, state or blue sky securities agencies and foreign
jurisdictions, including the preparation of prospectuses and statements of
additional information for filing with such regulatory authorities; (vii) all
expenses of shareholders' and Board meetings and of preparing, printing and
distributing prospectuses, notices, proxy statements and all reports to
shareholders and to governmental agencies; (viii) charges and expenses of legal
counsel to the Fund and the Board; (ix) any distribution fees paid by the Fund
in accordance with Rule 12b-1 promulgated by the Commission pursuant to the 1940
Act; (x) compensation and expenses of the Board; (xi) the cost of preparing and
printing share certificates; (xii) interest on borrowed money, if any; and
(xiii) any other expense that the Fund, the Adviser or any other agent of the
Fund may incur (A) as a result of a change in the law or regulations, (B) as a
result of a mandate from the Board with associated costs of a character
generally assumed by similarly structured investment companies or (C) that is
similar to the expenses listed above, and that is approved by the Board
(including a majority of the Independent Trustees) as being an appropriate
expense of the Fund. The Fund or the Adviser, as the case may be, shall
reimburse the Sub-Adviser for any such expenses or other expenses of the Fund or
the Adviser, as may be reasonably incurred by such Sub-Adviser on behalf of the
Fund or the Adviser. The Sub-Adviser shall keep and supply to the Fund and the
Adviser adequate records of all such expenses.

     in the best interests of the Funds including requiring any of its personnel
     with knowledge of the

                                       8



     Fund's activities to place the interest of the Fund first, ahead of their
     own interests, in all personal trading scenarios that may involve a
     conflict of interest with the Fund.

          (i) Representations. The representations and warranties in this
     Section 7 shall be deemed to be made on the date this Agreement is executed
     and at the time of delivery of the monthly compliance report required by
     Section 3(a), whether or not specifically referenced in such certificate.

          (j) Use Of The Name "Cullen". Subject to any notice provided to the
     Adviser pursuant to Section 15, the Sub-Adviser represents and warrants
     that is has the right to use the name "Cullen" in connection with its
     services to the Fund and that there are no threatened or existing actions,
     claims, litigation or proceedings that would adversely affect or prejudice
     the rights of the Sub-Adviser, Adviser or Fund to use the name "Cullen,"
     subject to the provisions of Section 15 below.

     8. Sub-Adviser's Compensation. The Adviser shall pay to the Sub-Adviser, as
compensation for the Sub-Adviser's services hereunder, a fee, determined as
described in Schedule A that is attached hereto and made a part hereof. Such fee
shall be computed daily and paid monthly in arrears by the Adviser. The Fund
shall have no responsibility for any fee payable to the Sub-Adviser. In the
event that the fee paid to the Adviser for managing the Fund is reduced by
regulatory authorities or the Board for any reason whatsoever, the fee hereunder
shall be subject to the same percentage reduction.

     The method for determining net assets of the Fund for purposes hereof shall
be the same as the method for determining net assets for purposes of
establishing the offering and redemption prices of Fund shares as described in
the Fund's prospectus. In the event of termination of this Agreement, the fee
provided in this Section shall be computed on the basis of the period ending on
the last business day on which this Agreement is in effect subject to a pro rata
adjustment based on the number of days elapsed in the current month as a
percentage of the total number of days in such month.

     9. Independent Contractor. In the performance of its duties hereunder, the
Sub-Adviser is and shall be an independent contractor and, unless otherwise
expressly provided herein or otherwise authorized in writing, shall have no
authority to act for or represent the Fund or the Adviser in any way or
otherwise be deemed to be an agent of the Fund or the Adviser. If any occasion
should arise in which the Sub-Adviser gives any advice to its clients concerning
the shares of the Fund, the Sub-Adviser will act solely as investment counsel
for such clients and not in any way on behalf of the Fund.

     10. Assignment and Amendments. This Agreement shall automatically
terminate, without the payment of any penalty, in the event of (i) its
assignment, including any change in control, as defined in the 1940 Act, of the
Adviser or the Sub-Adviser, or (ii) in the event of the termination of the
Management Agreement; provided that such termination shall not relieve the
Adviser or the Sub-Adviser of any liability incurred hereunder.

                                       9



     This Agreement may not be added to or changed orally and may not be
modified or rescinded except by a writing signed by the parties hereto and in
accordance with the 1940 Act, when applicable.

     11. Duration and Termination.

     (a) This Agreement shall become effective as of the date executed and shall
remain in full force and effect continually thereafter, subject to renewal and
unless terminated automatically as set forth in Section 12 hereof or until
terminated as follows:

          (i) The Adviser may at any time terminate this Agreement as to the
     Fund by not more than sixty (60) days' nor less than thirty (30) days'
     written notice delivered or mailed by registered mail, postage prepaid, to
     the Sub-Adviser. In addition, the Fund may cause this Agreement to
     terminate with respect to the Fund either (i) by vote of the Board or (ii)
     upon the affirmative vote of a majority of the outstanding voting
     securities of the Fund; or

          (ii) The Sub-Adviser may at any time terminate this Agreement by not
     more than sixty (60) days' nor less than thirty (30) days' written notice
     delivered or mailed by registered mail, postage prepaid, to the Adviser; or

          (iii) This Agreement shall automatically terminate on December 31st of
     any year, beginning on December 31, 2006, in which its terms and renewal
     shall not have been approved by (A) (i) a majority vote of the Board or
     (ii) the affirmative vote of a majority of the outstanding voting
     securities of the Fund; provided, however, that if the continuance of this
     Agreement is submitted to the shareholders of the Fund for their approval
     and such shareholders fail to approve such continuance of this Agreement as
     provided herein, the Sub-Adviser may continue to serve hereunder as to the
     Fund in a manner consistent with the 1940 Act and the rules and regulations
     thereunder; and (B) a majority vote of the Trustees who are not "interested
     persons" (as set forth in the 1940 Act, subject, however, to such
     exemptions as may be granted by the Commission under the 1940 Act or any
     interpretations of the staff of the Commission) of the Fund, the Adviser or
     the Sub-Adviser, at a meeting called for the purpose of voting on such
     approval.

     (b) For the purposes of this Agreement, "Affirmative vote of a majority of
the outstanding voting securities of the Fund" shall have the meaning set forth
in the 1940 Act, subject, however, to such interpretations of the staff of the
Commission.

     Termination of this Agreement pursuant to this Section shall be without
payment of any penalty.

     In the event of termination of this Agreement for any reason, the
Sub-Adviser shall, immediately upon notice of termination or on such later date
as may be specified in such notice, cease all activity on behalf of the Fund and
with respect to any of its assets. In addition, the Sub-Adviser shall deliver
the Fund's Books and Records to the Adviser (it being agreed that the
Sub-Adviser may keep copies of the Fund's Books and Records) by such means and
in accordance

                                       10



with such schedule as the Adviser shall reasonably direct and shall otherwise
reasonably cooperate in the transition of portfolio asset management to any
successor of the Sub-Adviser, including the Adviser, for a period up to
thirty-days (30) from such termination.

     12. Liability of the Sub-Adviser. The Sub-Adviser shall not be liable to
the Advisor or Adviser Indemnitees (as defined below) for any losses, claims,
damages, liabilities or litigation (including legal and other expenses) incurred
or suffered by an Adviser Indemnitee as a result of any error of judgment or
mistake of law by the Sub-Adviser with respect to the Fund, except that nothing
in this Agreement shall operate or purport to operate in any way to exculpate,
waive or limit the liability of the Sub-Adviser for, and the Sub-Adviser shall
indemnify and hold harmless the Adviser, the Fund and all affiliated persons
thereof (within the meaning of Section 2(a)(3) of the 1940 Act) and all
controlling persons (as described in Section 15 of the 1933 Act) (collectively,
the "Adviser Indemnitees") against any and all losses, claims, damages,
liabilities or litigation (including reasonable legal and other expenses) by
reason of or arising out of: (a) the Sub-Adviser being in violation of any
applicable federal or state law, rule or regulation or any investment policy or
restriction set forth in the Fund's Registration Statement or any written
guidelines or instruction provided in writing by the Board or the Adviser unless
acting at the direction of the Adviser or the Board, (b) the Fund's failure to
satisfy the diversification or source of income requirements of Subchapter M of
the Code by reason of any action or omission of the Sub-Adviser, unless acting
at the direction of the Adviser or the Board, (c) the Sub-Adviser's willful
misfeasance, bad faith or gross negligence generally in the performance of its
duties hereunder or its reckless disregard of its obligations and duties under
this Agreement provided that the Sub-Adviser's obligation in this regard shall
be reduced to the extent it is caused by or is otherwise directly related to the
Fund's or the Adviser's own willful misfeasance, bad faith or gross negligence
or to the reckless disregard of its duties under the Agreement or (d) the Fund
being in violation of any applicable federal or state law, rule or regulation or
any investment policy or restriction set forth in the Fund's Registration
Statement or any written guidelines or instruction provided in writing by the
Board or the Adviser, by reason of any action or omission of the Sub-Adviser
unless acting at the direction of the Board or the Adviser.

     13. Limitation of Liability. The parties to this Agreement acknowledge and
agree that no Trustee, officer or holder of shares of beneficial interests of
the Fund shall be liable for any litigation arising hereunder, whether direct or
indirect. The Fund's Certificate of Trust, as amended from time to time, is on
file in the Office of the Secretary of State of the State of Delaware. Such
Certificate of Trust and the Fund's Agreement and Declaration of Trust describe
in detail the respective responsibilities and limitations on liability of the
Trustees, officers, and holders of shares of beneficial interest.

     14. Non-Exclusivity. The services provided by the Sub-Adviser are not to be
deemed exclusive except as otherwise mutually agreed upon in writing, from time
to time by the parties hereto, and the Sub-Adviser shall be free to render
similar services to others so long as such services do not impair the services
rendered to the Adviser or the Fund.

     15. Name of the Fund. The parties agree that the Fund may use the name
"Cullen" and any logos or service marks that the Sub-Adviser may furnish to the
Fund (collectively, the

                                       11



"Identifying Marks") only so long as (i) this Agreement remains in effect and
(ii) the Sub-Adviser has the right to use such Identifying Marks. Any use of the
Identifying Marks pursuant to this Section 9 shall be royalty free. Upon
termination of this Agreement, the Fund promptly shall discontinue the use of
the Identifying Marks. Upon notification from the Sub-Adviser to the Fund that
the Sub-Adviser ceases to have the right to use an Identifying Mark, the Fund
promptly shall discontinue the use of such Identifying Mark. The Fund
acknowledges that (i) it has no proprietary or exclusive rights in the
Identifying marks and (ii) the Sub-Adviser reserves to itself the right to grant
the nonexclusive right to use any Identifying Marks to other persons (including
other investment companies), subject to the Sub-Adviser's right with respect to
such Identifying Marks.

     16. Jurisdiction. This Agreement shall be governed by and construed in
accordance with the substantive laws of The Commonwealth of Massachusetts and
the Sub-Adviser consents to the jurisdiction of courts, both state or federal,
in Boston, Massachusetts, with respect to any dispute under this Agreement.

     17. Paragraph Headings. The headings of paragraphs contained in this
Agreement are provided for convenience only. They form no part of this Agreement
and shall not affect its construction.

     18. Counterparts. This Agreement may be executed simultaneously in two or
more counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

     19. Severability. If any provision of this Agreement is held invalid or
unenforceable for any reason, such provision will be fully severable, and this
Agreement will be enforced and construed as if such provision had never
comprised a part of this Agreement. To the extent required, any provision of
this Agreement may be modified by a court of competent jurisdiction to preserve
its validity
