      time to time, except to the extent failure to do so could not reasonably
      be expected to have an Adverse Effect;

            (b) subject to its fiduciary obligations to the Funds, use its best
      efforts, which are commercially reasonable in relation to the consequences

      change is permitted by the terms thereof) in the amount of computation of

      not be taken, it shall, prior to taking any action inconsistent with the
      actions described in clauses (a) and (b) above, or failing to take any
      action it could otherwise take, or to any termination referred to in
      clause (b) above: (i) notify the Purchaser and the Program Administrator
      in writing of the nature of such failure or inability or termination and

      such failure or inability is required in order to comply with such
      fiduciary obligations;

            (c) provide prompt written notice to the Purchaser and the Program
      Administrator of any action by its board of directors, the board of

      modification which affects the amount of the Asset Based Sales Charge or

      affects the amount of its Asset Based Sales Charge or Contingent Deferred
      Sales Charge whether or not such modification is permitted by the terms
      thereof), amendment or supplement to, or any waiver of any provisions of,
      or any termination, of any Distribution Plan, any Distributor's Contract
      any Advisory Agreement, any Conversion Feature, any Redemption Feature,

      Investment Objectives and Policies of any Company in respect of any Fund,
      or any modification, amendment, supplement or waiver in the amounts
      payable or actually being paid thereunder, each as in effect on the date

      supplement or waiver could reasonably be expected to give rise to an
      Adverse Effect;

            (e) not use any trade names or assumed names other than Pioneer
      Funds Distributor, Inc., unless and until it has notified the Program
      Administrator and the Purchaser has amended all filings made under the UCC

      contemplated hereby to reflect such change and has taken such other action
      as the Program Administrator may reasonably request in connection
      therewith to avoid any Adverse Effect;

            (g) not move its chief executive office or the place where it keeps
      its records concerning the Purchased Portfolio Assets from the offices
      specified in Section 4.03(k), unless (a) it shall have given to the
      Program Administrator not less than twenty (20) days prior written notice
      of its intention to do so, clearly describing the new location and (b) it
      shall have taken such action as is reasonably requested by the Program
      Administrator and the Purchaser to maintain the title or ownership of the

      efforts, which are commercially reasonable in relation to the consequence
      to the Purchaser if they are not successful, to maintain the Fundamental

      Objectives and Policies notify the Purchaser and the Program Administrator
      in writing of the nature of such change;

            (c) use its best efforts to cause each Company to comply with all
      Applicable Law, except for such noncompliance as could not reasonably be
      expected to give rise to an Adverse Effect;

      a Fund to take the actions described in clauses (a) and (b) above, or in
      the event that despite its efforts such action will not be taken, it

Administrator may proceed to exercise any right or remedy which it might have
pursuant to this Article VII or Applicable Law without regard to any actions or

Servicer Agent), or any other Sponsor Entity is entitled under the Program
Documents. The obligations of the Parent under this Article VII shall not be
subject to any defense, counterclaim or offset which the Parent, the Advisor,
the Distributor (as Distributor Program Servicer Agent), or any other Person has
or may have against the Purchaser, the Program Administrator, any Indemnified
Party or any other Person, except such defense, counterclaim or offset which is
expressly allowed under this Agreement and the other Program Documents to such
Party and shall not have been previously adjudicated in any prior action against
such Party, but nothing herein shall limit the right of the Parent to pursue any
claim in a separate action.

                                MISCELLANEOUS

delay on the part of the Program Administrator or any Purchaser or any
Indemnified Party exercising any right, power or remedy hereunder or under any
other Program Document shall operate as a waiver thereof, nor shall any single

further exercise thereof or the exercise of any other right, power or remedy.
The remedies provided for herein are cumulative and are not exclusive of any
remedies that may be available to the Program Administrator and the Purchaser,
at law or in equity. No amendment, modification, supplement, termination or

specific instance and for the specific purpose for which given. No notice to or
demand on any party to this Agreement or any other Program Document in any case
shall entitle a Sponsor Entity to any other or further notice or demand in
similar or other circumstances.

Exchange Commission. Asterisks denote such omissions.

periodic auditing expenses in connection with the transactions contemplated by
this Agreement and the other Program Documents, and (iv) all reasonable fees and
disbursements of counsel in connection with the foregoing; PROVIDED, HOWEVER, if
the fees and expenses of counsel for the Purchaser and the Program Administrator
described in clause (i) above relating to services rendered on or prior to the
Purchase Date exceed $[  **  ] the Parent will only be responsible for fifty
percent (50%) of such excess.

            (b) INDEMNIFICATION. The Parent agrees to indemnify and hold
harmless the Purchaser (and, without duplication, its respective Investors),
each Placement Trust (and, without duplication, its respective Investors), the
Program Administrator, the Collection Agent, the Placement Agent, and each of
their respective Affiliates and the respective officers, directors, employees,
trustees, agents and advisors of, and any Person controlling, any of the
foregoing (each, an "INDEMNIFIED PARTY") from and against any and all damages,
losses, liabilities, expenses, obligations, penalties, actions, suits, judgments
and disbursements of any kind or nature whatsoever (including the reasonable
fees and disbursements of counsel) (collectively the "LIABILITIES") that are
incurred by or asserted or awarded against any Indemnified Party, in each case
arising out of or in connection with (and regardless of whether or not any such
transactions are consummated) any of the transactions contemplated by this
Agreement, the Purchase Agreement, the Program Servicer Agent Agreement, and the
Program Collection Agency Agreement, including without limitation, any one or
more of following:

                 (i)   any failure or alleged (by Persons other than an
            Indemnified Party) failure by any Sponsor Entity to perform any of
            its obligations, covenants, or agreements contained in any Program
            Document to which it is a party promptly and fully;

                 (ii)  any representation or warranty made or deemed made by any
            Sponsor Entity contained in any Program Document or in any
            certificate, written statement or report delivered by or on behalf
            of any such Person in connection herewith or therewith is, or is
            alleged (by Persons other than an Indemnified Party) to have been
            false or misleading in any respect when made;

                 (iii) any proceeding by or against any Sponsor Entity seeking
            to adjudicate such Person bankrupt or insolvent, or seeking
            liquidation, winding up, administration, reorganization,
            arrangement, adjustment, protection, relief, or composition of such
            Person or the debts of such Person under any law relating to
            bankruptcy, insolvency, liquidation, administrative, reorganization
            or relief of debtors, or seeking the entry of an order for relief or
            the appointment of a receiver, trustee, custodian, administrator,
            liquidator, or other similar official for such Person or for a
            substantial part of such Person's property, or the adoption by any
            Fund of a Liquidation Plan;

                 (iv)  any change in Control of the Parent, the Distributor or
            the Advisor which does not meet the requirements set forth in
            Section 5.02(h)(1) or (2); and



                                       32


<PAGE>   37

                  (v)  preparation for a defense of, any investigation,
            litigation or proceeding arising out of any of the transactions,
            events or circumstances described above;

            PROVIDED, HOWEVER, that the Parent shall not be required to
indemnify any Indemnified Party in respect of any Liability to the extent such
Liability (A) results directly and primarily from such Indemnified Party's gross
negligence, willful misconduct or violation of Applicable Law, in each case
except to the extent that the same is attributable to, or would not have
occurred but for, one or more of the events or circumstances described in
clauses (i) through (iv) above, or (B) arises out of the Purchased Portfolio
Assets proving to be uncollectible in whole or in part or declining in value
(including such as is attributable to the effect of market forces on the Net
Asset Value of the Funds), except to the extent that such uncollectibility or
decline in value is attributable to, or would not have occurred but for, one or
more of the events or circumstances described in clauses (i) through (iv) above,
or (C) arises out of a subsequent sale or assignment of the Purchased Portfolio
Assets by the Purchaser except to the extent that the same is attributable to,
or would not have accrued but for, one or more of the events or circumstances
described in clauses (i) through (iv) above, or (D) arises from a failure to
comply with Fundamental Investment Objectives of such Fund to the extent that
the Advisor shall have made restitution to the Fund promptly after such failure
in such amount, if any, which has been approved by the board of trustees of such
Fund or (E) constitutes Consequential Damages.

            (c) Unless the Parent shall have assumed responsibility for
contesting a Liability as provided in the next sentence, the Indemnified Party
may, but shall have no obligation to, contest, settle or compromise such
Liability. The Parent may pursue, at its sole cost and expense, such lawful
rights as are available at law to contest any Liability asserted against any
Indemnified Party provided: (i) the Parent has assumed responsibility for such
contest and conceded in writing its responsibility to indemnify the Indemnified
Party, in accordance with this Section, for the full amount of such Liability;
(ii) such contest is conducted in a manner which does not result in a Lien on
the Portfolio Assets unless the Parent shall have indemnified the Indemnified
Parties in respect thereof to their reasonable satisfaction and, if the manner
of contest does not defer the obligation to pay the Liability, the Parent shall
pay such Liability when due, subject to the right to recover such Liability if
the contest is successful, (iii) the Parent shall have provided to the
Indemnified Party such undertakings as the Indemnified Party shall reasonably
request, in form and substance satisfactory to the Indemnified Party, whereby
the Parent agrees to hold the Indemnified Party harmless from any and all
liabilities, costs and expenses which may arise as a consequence of such contest
except due to such Indemnified Party's own gross negligence or willful
misconduct; (iv) there is a meritorious basis for such contest; (v) the contest
of such Liability may be conducted in a manner which does not affect the
liability of the Indemnified Party for any liability not indemnified by the
Parent; (vi) the contest of such Liability can be separated from any contest of
any other liability in respect of which the Parent has not indemnified the
Indemnified Party without prejudicing the Indemnified Party's ability to deal
with or otherwise contest such other liability; PROVIDED THAT in the event the
contest of such Liability cannot be so separated, the Indemnified Party shall
not, without the prior written consent of the Parent, which consent shall not be
unreasonably withheld or delayed, effect any settlement of such Liability,
unless the Indemnified Party has waived in writing its right to be indemnified
for such Liability by the Parent; and (vii) the Indemnified 



                                       33


<PAGE>   38

Party has not waived its right to indemnification by the Parent in respect of
such Liability. The Parent shall keep the Indemnified Party fully advised on a
current basis concerning any such contest. Without limiting the foregoing, if
such contest involves or could involve a claim or counterclaim for relief by
either party other than for money damages: (A) the Parent shall give the
Indemnified Party reasonable notice of and a reasonable opportunity to be
present in person or by counsel at any proceeding in connection therewith; (B)
the Parent shall give the Indemnified Party notice of any proposed filings or
papers to be served or filed by the Parent in connection with any such
proceedings and a reasonable opportunity to comment upon them; and (C) the
Parent shall promptly supply the Indemnified Party with copies of any filings or
papers served upon the Parent in connection with such proceedings; it being
understood that the Indemnified Party shall bear its own costs incurred in
connection with any participation by the Indemnified Party or its counsel in the
contest as contemplated by this sentence.

            (d) Without prejudice to the survival of any other agreement of the
Parent, hereunder, the agreements and obligations of the Parent contained in
this Section 8.04 and of the Parent in Article VII shall survive the termination
of this Agreement.

            Section 8.05. TAXES. (a) Any and all payments by any Sponsor Entity,
any Transfer Agent, any Company or any Fund under this Agreement, any
Irrevocable Payment Instrument or any other Program Document shall be made free
and clear of and without deduction for any and all present or future taxes,
levies, imposts, deductions, charges or withholdings, and all liabilities with
respect thereto, EXCLUDING, taxes imposed on the recipient's income, and
franchise taxes imposed on the recipient, by (i) the United States federal
government, (ii) the jurisdiction under the laws of which the recipient is
organized or any political subdivision thereof, (iii) the jurisdiction in which
is located the principal executive office of the recipient or any political
subdivision thereof or (iv) any other jurisdiction which asserts the authority
to impose such tax on the basis of contacts the recipient maintains with such
jurisdiction other than the contacts arising out of the transactions
contemplated hereby (all such non-excluded taxes, levies, imposts, deductions,
charges, withholdings and liabilities being hereinafter referred to as "TAXES").
If any Sponsor Entity, any Transfer Agent, any Company or any Fund shall be
required by Applicable Law to deduct any Taxes from or in respect of any sum
payable hereunder or under any other Program Document, (i) the sum payable
hereunder or thereunder shall be increased as may be necessary so that after
making all required deductions (including deductions applicable to additional
sums payable under this Section 8.05) the recipient receives an amount equal to
the sum it would have received had no such deductions been made, (ii) such
Sponsor Entity, Transfer Agent, Company or Fund shall make such deductions and
(iii) such Sponsor Entity, Transfer Agent, Company or Fund shall pay the full
amount deducted to the relevant taxation authority or other authority in
accordance with Applicable Law.

            (b) In addition, the Parent agrees to pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies which arise from any transfer of Portfolio Assets from the
Distributor to the Purchaser in connection herewith or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement or any
other Program Document (hereinafter referred to as "OTHER TAXES").

<PAGE>   39

            (c) The Parent will indemnify the Program Administrator and the
Purchaser for the full amount of Taxes or Other Taxes (including any Taxes or
Other Taxes imposed by any jurisdiction on amounts payable under this Section
8.05) and any liability (including penalties, interest and expenses) arising
therefrom or with respect thereto, whether or not such Taxes or Other Taxes were
correctly or legally asserted, so long as there is a reasonable basis for the
assertion of such Taxes or Other Taxes. This indemnification shall be made
within 30 days from the date the Program Administrator or the Purchaser makes
written demand therefor to the Parent; provided that the Parent shall not be
required to indemnify for Taxes or other Taxes the imposition of which the
Program Administrator or the Purchaser shall have had Actual Knowledge and for
which the Program Administrator or the Purchaser shall have not given notice
within 90 days after having obtained such Actual Knowledge. The Purchaser and
the Program Administrator shall endeavor to avoid or reduce any Taxes or Other
Taxes subject to the foregoing indemnity; PROVIDED that they shall not be
required to take any action which, in their sole judgment, may subject them to
any adverse effect.

            (d) Within thirty (30) days after the date of any payment of Taxes,
the Parent will furnish to the Purchaser and the Program Administrator the
original or a certified copy of a receipt evidencing payment thereof.

            (e) In the event the Parent shall pay a Tax or Other Tax pursuant to
this Section 8.05 and all or a portion of such Tax or Other Tax previously paid
by the Parent is later refunded by the applicable taxing Authority, the
recipient of such refund shall pay to the Parent the portion of such refund
which relates to the amount previously paid by the Parent.

            (f) Unless the Parent shall have assumed responsibility for
contesting a Tax or Other Tax described in paragraph (c) of this Section 8.05 as
provided in the next sentence, the Program Administrator and the Purchaser may,
but shall have no obligation to, contest, settle or compromise such Tax or Other
Tax. The Parent may pursue, at its sole cost and expense, such lawful rights as
are available at law to contest any Tax or Other Tax asserted against the
Purchaser or the Program Administrator provided: (i) the Parent has assumed
responsibility for such contest and conceded in writing its responsibility to
indemnify the Purchaser or the Program Administrator, as the case may be, in
accordance with this Section, for the full amount of such Tax or Other Tax; (ii)
such contest is conducted in a manner which does not result in a Lien on the
Portfolio Assets unless the Parent shall have indemnified the Purchaser with
respect thereof in a manner reasonably satisfactory to the Purchaser and, if the
manner of contest does not defer the obligation to pay the Tax or Other Tax, the
Parent shall pay such Tax or Other Tax when due, subject to the right to recover
such Tax or Other Tax if the contest is successful, (iii) to the extent not
covered by Section 8.04(b), the Parent shall have provided to the Purchaser or
the Program Administrator, as the case may be, such undertakings as the
Purchaser or the Program Administrator, as the case may be, shall reasonably
request, in form and substance satisfactory to the Purchaser or the Program
Administrator, as the case may be, whereby the Parent agrees to hold the
Purchaser or the Program Administrator, as the case may be, harmless from any
and all liabilities, costs and expenses which may arise as a consequence of such
contest except due to the Program Administrator's or the Purchaser's own gross
negligence or willful misconduct; (iv) there is a meritorious basis for such
contest; (v) the contest of such Tax or Other Tax may be conducted in a manner
which does not affect the liability of the Purchaser or the Program
Administrator, as the case may be, for any tax not indemnified by the Parent;
(vi) the contest of 




                                       35

<PAGE>   40

such Tax or Other Tax can be separated from any contest of any other tax in
respect of which the Parent has not indemnified the Purchaser or the Program
Administrator, as the case may be, without prejudicing the Purchaser's or the
Program Administrator's, as the case may be, ability to deal with or otherwise
contest such other liability; PROVIDED, THAT if the contest of such Tax or Other
Tax can not be so separated, neither the Purchaser nor the Program
Administrator, as the case may be, shall, without the prior written consent of
the Parent, which consent shall not be unreasonably withheld or delayed, effect
any settlement of such Tax or Other Tax, unless the Purchaser or the Program
Administrator, as the case may be, has waived in writing its right to be
indemnified for such Tax or Other Tax by the Parent; and (vii) such Purchaser or
the Program Administrator, as the case may be, has not waived its right to
indemnification by the Parent in respect of such Tax or Other Tax. The Parent
shall keep the Purchaser or the Program Administrator, as the case may be, fully
advised on a current basis concerning any such contest. Without limiting the
foregoing, if such contest involves or could involve a claim or counterclaim for
relief by either party other than for money damages: (A) the Parent shall give
the Purchaser or the Program Administrator, as the case may be, reasonable
notice of and a reasonable opportunity to be present in person or by counsel at
any proceeding in connection therewith; (B) the Parent shall give the Purchaser
or the Program Administrator, as the case may be, notice of any proposed filings
or papers to be served or filed by the Parent in connection with any such
proceedings and a reasonable opportunity to comment upon them; and (C) the
Parent shall promptly supply the Purchaser or the Program Administrator, as the
case may be, with copies of any filings or papers served upon the Parent in
connection with such proceedings; it being understood that the Purchaser or the
Program Administrator, as the case may be, shall bear its own costs incurred in
connection with any participation by the Purchaser or the Program Administrator,
as the case may be, or its counsel in the contest as contemplated by this
sentence.

            (g) Without prejudice to the survival of any other agreement of the
Parent, hereunder, the agreements and obligations of the Parent contained in
this Section 8.05 shall survive the termination of this Agreement.

            Section 8.06. EXECUTION IN COUNTERPARTS. This Agreement and each
other Program Document may be executed in any number of counterparts and by
different parties hereto on separate counterparts, each of which counterparts,
when so executed and delivered, shall be deemed to be an original and all of
which counterparts, taken together, shall constitute but one and the same
agreement.

            Section 8.07. BINDING EFFECT; ASSIGNMENT. This Agreement and the
various representation and covenants set forth herein shall be binding upon the
parties hereto and their respective successors and assigns, and inure to the
benefit of the parties hereto and their respective Investors, successors and
assigns. No Sponsor Entity shall assign its rights or obligations hereunder or
under any other Program Document or in connection herewith or therewith or any
interest herein or therein (voluntarily, or by operation of law or otherwise)
without the Program Administrator's and the Purchaser's prior written consent,
except as otherwise expressly permitted hereunder and thereunder. This Agreement
and the Program Administrator's and the Purchaser's rights herein, and in the
Purchased Portfolio Assets, the Program Collections and the Ancillary Rights
with respect thereto shall be assignable, in whole or in part, by the Purchaser
and the Program Administrator and their respective successors and 




                                       36




<PAGE>   41

assigns; provided, that no delegation of the Purchaser's or the Program
Administrator's obligations hereunder shall be permitted without prior written
notice to the Sponsor Entities.

            Section 8.08. GOVERNING LAW; SUBMISSION TO JURISDICTION. (A) THIS
AGREEMENT SHALL BE DEEMED TO BE A CONTRACT MADE UNDER THE LAWS OF THE STATE OF
NEW YORK AND FOR ALL PURPOSES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF SAID STATE WITHOUT REGARD TO ITS CONFLICTS OF LAWS PROVISIONS.

            (b) Each of the Advisor, the Parent and the Distributor hereby
irrevocably submits itself to the non-exclusive jurisdiction of the courts of
the State of New York and to the non-exclusive jurisdiction of any Federal Court
of the United States located in the Southern District of New York, for the
purposes of any suit, action or other proceeding arising out of this Agreement,
the Purchase Agreement, the Program Servicer Agent Agreement, or the Program
Collection Agency Agreement or any of the transactions contemplated hereby or
thereby.

            Section 8.09. SEVERABILITY OF PROVISIONS. Any provision of this
Agreement which is prohibited or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof or
affecting the validity or enforceability of such provision in any other
jurisdiction.

            Section 8.10. CONFIDENTIALITY. Unless otherwise required by
Applicable Law, the parties hereto agree to maintain the confidentiality of this
Agreement, the Purchase Agreement, the Program Servicer Agent Agreement, or the
Program Collection Agency Agreement (and all drafts hereof and thereof) other
than the Distributor's Contracts, the Distribution Plans and the Prospectuses
and the transactions contemplated thereby, and all information disclosed to such
party by another party and identified by such party as non-public information
pursuant to or in connection with this Agreement, the Purchase Agreement, the
Program Servicer Agent Agreement, or the Program Collection Agency Agreement
which has not become public other than as a result of a breach of this
undertaking (all of the foregoing, the "CONFIDENTIAL INFORMATION"), in
communications with third parties and otherwise; PROVIDED, that Confidential
Information may be disclosed (i) to assignees, participants and potential
assignees and participants of the Purchaser and the Program Administrator
provided that confidentiality arrangements with such third parties are put in
place by the Purchaser or the Program Administrator, (ii) to third parties to
the extent such disclosure is consented to in writing by all parties to this
Agreement, in the case of this Agreement, the Purchase Agreement, the Program
Servicer Agent Agreement, or the Program Collection Agency Agreement, or the
party to which the Confidential Information relates, in the case of other
Confidential Information (which consent shall not be unreasonably withheld) and
such disclosure is made pursuant to a written confidentiality agreement in form
and substance substantially identical to this Section 8.10, (iii) the officers,
partners, directors and employees, legal counsel and internal and external
auditors of the parties hereto, (iv) as the Program Administrator or the
Purchaser may deem necessary or appropriate in connection with any Placement or
its warehouse financing arrangements, provided, that prior to disclosing such
Confidential Information (other than the performance of the Portfolio Assets)
concerning any Sponsor Entity in any offering memorandum in connection with any
Placement, the Program Administrator will give the Sponsor Entity a reasonable
opportunity to comment on such proposed disclosure and will 


                                       37


<PAGE>   42

discuss in good faith any reasonable comments of the Sponsor Entity and use
reasonable efforts, consistent with its marketing and business objectives and
Applicable Law, to address such comments in a mutually satisfactory manner, (v)
in connection with any litigation or the protection or enforcement of a party's
rights and remedies under or relating to this Agreement, the Purchase Agreement,
the Program Servicer Agent Agreement, or the Program Collection Agency Agreement
and (vi) in response to a lawful requirement of any Authority exercising
supervisory jurisdiction over the disclosing Party or its Affiliates.

            Section 8.11. INTENT OF AGREEMENT. It is the intention of this
Agreement and the Purchase Agreement that the purchase of Purchased Portfolio
Assets under the Purchase Agreement shall convey to the Purchaser an undivided
100% ownership interest in such Purchased Portfolio Assets on the Purchase Date
therefor and that such transaction shall constitute a True Sale and not a
secured loan. If, notwithstanding such intention, any conveyance of Purchased
Portfolio Assets from the Distributor to the Purchaser shall ever be
recharacterized as a secured loan and not a sale, it is the intention of this
Agreement and the Purchase Agreement that such agreements shall constitute
collectively a security agreement under Applicable Law, and that the Distributor
shall be deemed to have granted to the Purchaser, and hereby does so grant, a
duly perfected first priority security interest in all of the Distributor's
right, title and interest in, to and under such Purchased Portfolio Assets free
and clear of any Adverse Claim.

            Section 8.12. CONTINUING OBLIGATIONS. Notwithstanding any other
provision of this Agreement or the other Program Documents, to the extent that
any obligation of the Sponsor Entities under the Program Documents, pursuant to
and in connection with the Purchased Portfolio Assets remains unperformed or
executory, the Sponsor Entities shall be obligated to perform such obligation to
the same extent as if the purchase and sale contemplated hereby had not taken
place, and the Purchaser and the Program Administrator shall not be required or
obligated in any manner to perform or fulfill any of the obligations of the
Sponsor Entities under, pursuant to or in connection with any Purchased
Portfolio Assets.

            Section 8.13. MERGER. This Agreement, the Purchase Agreement, the
Program Servicer Agent Agreement and the Program Collection Agency Agreement
taken as a whole incorporate the entire agreement between the parties thereto
concerning the subject matter thereof. This Agreement, the Purchase Agreement,
the Program Servicer Agent Agreement and the Program Collection Agency Agreement
supersede any prior agreements among the parties relating to the subject matter
thereof.

            Section 8.14. FURTHER ACTS. Each party agrees that at any time, and
from time to time, it will do all such things and execute and deliver all such
instruments, assignments, other documents and assurances, as such other party or
its counsel reasonably deems necessary or desirable in order to carry out the
express intent, purpose and conditions of this Agreement, the Purchase
Agreement, the Program Servicer Agent Agreement and the Program Collection
Agency Agreement and the transactions contemplated hereby and thereby, and
without limiting the generality of the foregoing, to the extent permitted by
Applicable Law, upon the Program Administrator's written request from time to
time, the Parent, the Distributor (as Distributor and as Program Servicer Agent)
and the Advisor shall make, execute, acknowledge and deliver and file and record
in the proper filing and recording places all such instruments, and take all
such 



                                       38




<PAGE>   43

actions, as the Program Administrator may reasonably deem necessary or advisable
for assuring or confirming to the Purchaser its rights and interest in and to,
and remedies in respect of, the Purchased Portfolio Assets. In addition, the
Advisor, the Distributor (as Distributor and as Program Servicer Agent) and the
Parent, agree to do all things and execute and deliver all instruments,
assignments, other documents and assurances, as the Program Administrator or its
counsel reasonably deems necessary to permit the Purchaser to convey any portion
of its right, title and interest in the Purchased Portfolio Assets and the
Program Documents in connection with any assignment by such Purchaser permitted
by this Agreement, the Purchase Agreement, the Program Servicer Agent Agreement
and the Program Collection Agency Agreement.

            Section 8.15. SPECIFIC PERFORMANCE; OTHER RIGHTS AND REMEDIES. The
parties hereto recognize that certain of their rights under this Agreement and
the other Program Documents are unique and, accordingly, the parties hereto
shall, in addition to such other remedies as may be available to any of them at
law or in equity or under this Agreement and the other Program Documents, have
the right to enforce their rights hereunder and thereunder by actions for
injunctive permitted relief and specific performance to the extent permitted by
Applicable Law. The rights and remedies of the Program Administrator and the
Purchaser under this Agreement and the other Program Documents are cumulative
and are not in lieu of, but are in addition to, any other rights and remedies
which the Program Administrator and the Purchaser may have under or by virtue of
any Applicable Law, or in equity, or any other agreement or obligations to which
the Program Administrator and the Purchaser are parties. The rights and remedies
of the Program Administrator and the Purchaser under this Agreement and the
other Program Documents may be exercised from time to time and as often as such
exercise is deemed expedient. Without limiting the generality of the foregoing,
the Distributor acknowledges and agrees that it will be impossible to measure in
money the damage to the Program Administrator or the Purchaser in the event of a
breach of any of the terms and provisions of this Agreement or any other Program
Document, and that, in the event of any such breach, the Program Administrator
and the Purchaser may not have an adequate remedy at law, although the foregoing
shall not constitute a waiver of any of the Program Administrator's or the
Purchaser's rights, powers, privileges and remedies against or in respect of a
breaching party, any collateral or any other Person or thing under this
Agreement, any other Program Document or Applicable Law. It is therefore agreed
that each of the Program Administrator and the Purchaser, in addition to all
other such rights, powers, privileges and remedies that it may have, shall be
entitled to injunctive relief, specific performance or such other equitable
relief as it may request to exercise or otherwise enforce any of the terms of
those provisions and to enjoin or otherwise restrain any act prohibited thereby,
and the Distributor shall not argue and hereby waives any defense that there is
an adequate remedy available at law.

            Section 8.16. NO PROCEEDINGS. Each Party agrees that it will not
institute against the Purchaser, or join any other Person in instituting against
the Purchaser, any insolvency proceeding (including any proceeding of the type
described in clause (e) of the definition of Event of Termination). The
foregoing shall not limit the right of any Party to file any claim in or
otherwise take any action in any insolvency proceeding that was instituted
against the Purchaser by any other Person.

            Section 8.17. ADDITIONAL COMPANIES AND FUNDS. Unless an Event of
Termination (or an event which, with the passage of time or notice, or both,
would constitute an Event of 


                                       39




<PAGE>   44

Termination) shall have occurred and be continuing, the Distributor may request
that an additional Eligible Fund become a "Fund" (and in connection therewith
any investment company, which is registered with the SEC under the Investment
Company Act, of which such Eligible Fund is a series, to become a Company) under
this Agreement on the Addition Effective Date in respect of such additional
Eligible Fund. On and as of such Addition Effective Date in respect of any
additional Eligible Fund, (i) such additional Eligible Fund shall become a Fund
hereunder and any investment company, which is registered with the SEC under the
Investment Company Act, of which such Fund is a series, shall become a Company
hereunder, (ii) this Agreement and the Purchase Agreement (including Schedule I
to the Master Agreement and Schedule I to the Purchase Agreement) shall be
deemed to be supplemented to reflect such addition, and (iii) any reference in
this Agreement to any change or modification since the date of this Agreement or
the Closing Date to the distributor's contract, distribution plan, advisory
agreement, prospectus or contingent deferred sales charge arrangement in respect
of such additional Eligible Fund shall be deemed to refer to any change or
modification thereof since such Addition Effective Date.

            The term "ADDITION EFFECTIVE DATE" shall mean with respect to any
additional Eligible Fund, the first date on which all of the following
conditions shall have been satisfied:

            (i)   the Program Administrator shall have received a fully executed
      Additional Eligible Fund Addendum, together with such signed opinions of
      counsel to the applicable Company, the Distributor, the Advisor, and the
      Parent, each dated a date reasonably near the Addition Effective Date, as
      the Program Administrator shall have reasonably requested, all in form,
      scope and substance satisfactory to the Program Administrator;

            (ii)  the Program Administrator shall have received such
      instruments, certificates and documents regarding the addition of such
      additional Eligible Fund from the Distributor, the Advisor, the Parent,
      and the applicable Company as the Program Administrator shall reasonably
      request; and

            (iii) the Program Administrator shall have received evidence
      satisfactory to it that (a) the conditions in respect of such additional
      Eligible Fund set forth in Section 3.02 immediately after the Addition
      Effective Date shall be satisfied, and (b) that on such Addition Effective
      Date the Portfolio Assets relating to such additional Eligible Fund shall
      constitute Eligible Portfolio Assets.

                        PROGRAM ALLOCATION PROCEDURES

            Program Collections in respect of Portfolio Assets which constitute
Contingent Deferred Sales Charges, and Asset Based Sales Charges related to
Shares of each Fund shall be allocated by the Program Administrator among the
Purchaser and the Distributor in accordance with this Schedule II.

            Defined terms used in this Schedule II and not otherwise defined
herein shall have the meaning assigned to them in Schedule X to the Master
Agreement. As used herein the following terms shall have the meanings indicated:

            "COMMISSION SHARE" means in respect of any Fund, each Share of such
Fund, which is issued under circumstances which would normally give rise to an
obligation of the holder of such Share to pay a Contingent Deferred Sales Charge
upon redemption of such Share (including, without limitation, any Share of such
Fund issued in connection with a Permitted Free Exchange) and any such Share
shall continue to be a Commission Share of such Fund prior to the redemption
(including a redemption in connection with a Permitted Free Exchange) or
conversion of such Share, even though the obligation to pay the Contingent
Deferred Sales Charge may have expired or conditions for waivers thereof may
exist.

            "DATE OF ORIGINAL ISSUANCE" means in respect of any Commission
Share, the date with reference to which the amount of the Contingent Deferred
Sales Charge payable on redemption thereof, if any, is computed.

            "FREE SHARE" means, in respect of any Fund, each Share of such Fund,
other than a Commission Share or Omnibus Share (including, without limitation,
any Share issued in connection with the reinvestment of dividends or capital
gains).

            "INCEPTION DATE" means in respect of any Fund, the first date on
which such Fund issued Shares.

            "NET ASSET VALUE" means, (i) with respect to any Fund, as of the
date any determination thereof is made, the net asset value of such Fund
computed in the manner such value is required to be computed by such Fund in its
reports to its shareholders, and (ii) with respect to any Share of such Fund as
of any date, the quotient obtained by dividing: (A) the net asset value of such
Fund (as computed in accordance with clause (i) above) allocated to Shares of
such Fund (in accordance with the constituent documents for such Fund) as of
such date, by (B) the number of Shares of such Fund outstanding on such date.

            "OMNIBUS SHARE" means, in respect of any Fund, a commission share
sold by one of the Selling Agents listed on Exhibit A or related free share
issued in connection with the reinvestment of 




                                      II-1


<PAGE>   50

dividends or capital gains for such share. If, subsequent to closing of the
Program, the Program Administrator reasonably determines that the Program
Servicer Agent is able provide information to track all commission shares sold
by any of the Selling Agents listed on Exhibit A (and related free shares in the
same manner as Commission Shares and Free Shares are currently tracked in
respect of Selling Agents not listed on Exhibit A, then Exhibit A shall be
amended to delete such Selling Agent from Exhibit A so that commission shares
sold by such Selling Agent (and related free shares) will thereafter be treated
as Commission Shares and Free Shares.

PART I: ATTRIBUTION OF SHARES

            Shares of each Fund, which are outstanding from time to time, shall
be attributed to the Purchaser and the Distributor in accordance with the
following rules;

            (1) COMMISSION SHARES:

            (a) Commission Shares attributed to the Purchaser shall be
Commission Shares the Date of Original Issuance of which occurred on or after
the Inception Date of such Fund and on or prior to the last Purchase Cut-Off
Date occurring prior to the date of such determination.

            (b) Commission Shares attributable to the Distributor shall be
Commission Shares, the Date of Original Issuance of which occurs after the last
Purchase Cut-Off Date occurring prior to the date of such determination.

            (c) A Commission Share of a particular Fund (the "ISSUING Fund")
issued in consideration of the investment of proceeds of the redemption of a
Commission Share of another Fund (the "REDEEMING FUND") in connection with a
Permitted Free Exchange, is deemed to have a Date of Original Issuance identical
to the Date of Original Issuance of the Commission Share of the Redeeming Fund
and any such Commission Share will be attributed to the Purchaser or the
Distributor based upon such Date of Original Issuance in accordance with rules
(a) and (b) above.

            (d) A Commission Share redeemed (other than in connection with a
Permitted Free Exchange) or converted to a Class A share is attributable to the
Purchaser or Distributor based upon the Date of Original Issuance in accordance
with rule (a), (b) and (c) above.

            (2) FREE SHARES:

            Free Shares of a Fund outstanding on any date shall be attributed to
the Purchaser or Distributor, as the case may be, in the same proportion that
the Commission Shares of such Fund outstanding on such date are attributed to it
on such date; PROVIDED that if the Program Administrator reasonably determines
that the Transfer Agent is able to produce monthly reports which track the Date
of Original Issuance for the Free Shares, then the Free Shares shall be
allocated pursuant to clause 1(a), (b) and (c) above.



                                      II-2



<PAGE>   51

            (3) OMNIBUS SHARES:

            Omnibus Shares of a Fund outstanding on any date shall be attributed
to the Purchaser or Distributor, as the case may be, in the same proportion that
the Commission Shares of such Fund outstanding on such date are attributed to it
on such date; PROVIDED that if the Program Administrator reasonably determines
that the Transfer Agent is able to produce monthly reports which track the Date
of Original Issuance for the Omnibus Shares, then the Omnibus Shares shall be
allocated pursuant to clause 1(a), (b) and (c) above.

PART II: ALLOCATION OF CONTINGENT DEFERRED SALES CHARGES ("CDSCS")

            (1) CDSCS RELATED TO THE REDEMPTION OF COMMISSION SHARES:

            CDSCs in respect of the redemption of Commission Shares shall be
allocated to the Purchaser or Distributor depending upon whether the related
redeemed Commission Share is attributable to the Purchaser or Distributor, as
the case may be, in accordance with Part I above.

            CDSCs in respect of the redemption of Omnibus Shares shall be
allocated to the Purchaser or Distributor shall be attributed to the Purchaser
or Distributor, as the case may be, in the same proportion that the CDSCs
Related to the Redemption of Commission Shares are attributed to it on such
date; PROVIDED that if the Program Administrator reasonably determines that the
Transfer Agent is able to produce monthly reports which track the Date of
Original Issuance for the redeemed Omnibus Shares, then the CDSCs Related to the
Redemption of Omnibus Shares shall be allocated pursuant to clause 1 above.

PART III: ALLOCATION OF ASSET BASED SALES CHARGES

            Assuming that the Asset Based Sales Charge remains constant over
time and among Funds so that Part VI hereof does not become operative:

            (1) The portion of the aggregate Asset Based Sales Charges accrued
in respect of all Shares of all Funds during any calendar month allocable to the
Purchaser or Distributor is determined by multiplying the total of such Asset
Based Sales Charges by the following fraction:

                                (A + C)/2
                                ---------
                                (B + D)/2

where:



                                      II-3


<PAGE>   52

A =         The aggregate Net Asset Value of all Shares of all Funds
            attributed to the Purchaser or the Distributor, as the case may be,
            and outstanding at the beginning of such calendar month

B =         The aggregate Net Asset Value of all Shares of all Funds at the
            beginning of such calendar month

C =         The aggregate Net Asset Value of all Shares of all Funds
            attributed to the Purchaser or the Distributor, as the case may be,
            and outstanding at the end of such calendar month

D =         The aggregate Net Asset Value of all Shares of all Funds at the
            end of such calendar month

            (2) If the Program Administrator reasonably determines that the
Transfer Agent is able to produce automated monthly reports which allocate the
average Net Asset Value of the Commission Shares (or all Shares if available) of
all Funds among the Purchaser and Distributor in a manner consistent with the
methodology detailed in Part I and Part III(1) above, the portion of the Asset
Based Sales Charges accrued in respect of all such Shares of all Funds during a
particular calendar month will be allocated to the Purchaser or the Distributor
by multiplying the total of such Asset Based Sales Charges by the following
fraction:

                                    (A)/(B)

where:

A =         Average Net Asset Value of all such Shares of all Funds for such
            calendar month attributed to the Purchaser or the Distributor, as
            the case may be

B =         Total average Net Asset Value of all such Shares of all Funds for
            such calendar month

PART IV: ALLOCATION OF OTHER AMOUNTS (IF ANY)

            The allocation of amounts such as expense and indemnity payments
shall be accomplished in the following manner:

            1. The Program Administrator will determine whether any such amounts
are intended to (i) be distributed in a manner similar to Program Collections
("RECEIVABLE REIMBURSEMENT PAYMENT"), or (ii) reimburse a particular Person for
specific losses, cost, damages or other expenses other than losses for which a
Receivable Reimbursement Payment is being made ("EXPENSE PAYMENTS").

            2. Receivable Reimbursement Payments shall be allocated as nearly as
possible in the same manner as the Collections in respect of the Shares to which
they related would be allocated as provided in Parts I through III of this
Schedule II; PROVIDED, THAT, if any such payment by a particular payor is not
sufficient to replace the full amount required to be replaced by such payment,
such payment shall be allocated to each person to which the amount replaced
would have been allocated as nearly as practicable in the proportion that the
full amount of indemnification required to be made to such indemnitee from such
payor bears to the total amount of indemnification required to be made to all
such indemnitees from such payor.

PART V: ADJUSTMENT OF THE PURCHASER'S PORTION AND THE DISTRIBUTOR'S PORTION

            The Parties to the Program Documents recognize that, if the terms of
any Distributor's Contract, any Distribution Plan, any Prospectus, the Conduct
Rules or any other Applicable Law change, which change disproportionately
reduces, in a manner inconsistent with the intent of the Program Documents, the
amount of the Purchaser's Portion or the Distributor's Portion that would have
been payable on any Monthly Settlement Date had no such change occurred, the
definitions of the Purchaser's Portion and/or the Distributor's Portion in
respect of the Shares relating to such Fund shall be adjusted by agreement among
the Purchaser, the Distributor, the Program Administrator and the Funding and
Collection Agent; PROVIDED, HOWEVER, if the Purchaser, the Distributor, the
Program Administrator and the Funding and Collection Agent cannot agree within
thirty (30) days after the date of any such change in Applicable Laws or in any
Distributor's Contract, Distribution Plan, Prospectus or the Conduct Rules, the
Parties shall submit the question to arbitration in accordance with the
commercial arbitration rules of the American Arbitration Association and the
decision reached by the arbitrator shall be final and binding on the Parties
hereto. The Funding and Collection Agent shall be notified promptly in writing
by the Program Administrator of any adjustment in the Purchaser's Portion or the
Distributor's Portion or of any arbitration award pursuant to this Part V.

1998 (this "AGREEMENT"), between PIONEER FUNDS DISTRIBUTOR, INC. (the
"DISTRIBUTOR") and PLT FINANCE, L.P. (the "PURCHASER").

                             W I T N E S S E T H:

            WHEREAS, the Distributor and the Purchaser are parties to that
certain Pioneer Program Master Agreement dated as of the date hereof with the
"Parent," "Advisor," "Collection Agent" and "Program Administrator," each as
defined therein (the "MASTER AGREEMENT"); and

            WHEREAS, the Distributor desires to sell to the Purchaser, and the
Purchaser desires to purchase from the Distributor, from time to time, on the
terms and subject to the conditions specified in this Agreement and the Master
Agreement, the Purchased Portfolio Assets (defined as hereinafter provided);

            NOW, THEREFORE, in consideration of the foregoing premises, and the
mutual covenants and agreements herein contained, and for other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties hereto agree as follows:

                                    ARTICLE I

                       RULES OF CONSTRUCTION; DEFINITIONS

            Section 1.01. RULES OF CONSTRUCTION. The rules of construction set
forth in Schedule X to the Master Agreement shall be applied to this Agreement.

            Section 1.02. DEFINITIONS. Capitalized terms not expressly defined
herein, which are defined in Schedule X to the Master Agreement, shall have the
same meanings herein as in said Schedule.

                                   ARTICLE II

            Section 2.01 PURCHASE. On the Initial Purchase Date, the Distributor

<PAGE>   84

$62,330,000 subject to adjustments (which may be positive or negative) to be
determined prior to the Initial Purchase Funding Date by the Purchaser in
accordance with the next sentence (such adjusted amount, the "INITIAL PURCHASE
Price"). Adjustments to the $62,330,000 figure will be calculated using the same
methodology used to arrive at the $62,330,000 figure taking into account the
additional information required to be submitted pursuant to Section 5.01(v) of
the Master Agreement in order to reflect, on an individual Fund basis, Share
aging, cost basis and Net Asset Value of the Purchased Portfolio Assets as of
the close of business on September 30, 1998. On each Purchase Date (other than
the initial Purchase Date) until the Purchase Termination Date, the Distributor
hereby agrees to sell, transfer, convey and assign to the Purchaser, and the
Purchaser hereby agrees to purchase from the Distributor, in each case on the
terms and subject to the conditions set forth in this Agreement and in the
Master Agreement, all of the Distributor's right, title and interest in, to and
under all Purchased Portfolio Assets specified in the related Purchase Notice in
accordance with Section 2.02, such purchases to occur on Purchase Dates
established pursuant to Sections 2.02 and 2.03.

            Section 2.02. PURCHASE NOTICES. Subject to the satisfaction or
waiver by the Parent of Section 3.03(k) of the Master Agreement, monthly after
the date hereof and prior to the Purchase Termination Date, the Distributor
shall transmit or shall cause to be transmitted to the Program Administrator and
the Purchaser (with a copy to the Funding and Collection Agent), no later than
10:00 a.m. (New York City time) three Business Days prior to such proposed
Purchase Date, by facsimile transmission, a Purchase Notice establishing a
Purchase Date. The Distributor represents and warrants that the information set
forth in each Purchase Notice is true and correct.

            Section 2.03. TRANSFERS AND PAYMENTS. Subject to the terms and
conditions set forth herein and in the Master Agreement, the Distributor shall
convey to the Purchaser on each Purchase Date, and the Purchaser shall deposit
in the Purchaser's Funding Account funds sufficient to enable the Funding and
Collection Agent to pay to the Distributor the Purchase Price for, all Purchased
Portfolio Assets arising directly or indirectly out of Commission Shares of each
Fund the Date of Original Issuance of which occurs on or prior to the Purchase
Cut-Off Date specified in the Purchase Notice for the Purchase Date in question
and after (i) the Inception Date for such Fund, in the case of the initial
Purchase Date following such Inception Date or (ii) the immediately preceding
Purchase Cut-Off Date for all other Purchase Dates; PROVIDED, however, that in
the case of the Purchase on the Initial Purchase Date, the amount of the cash
deposit and payment required shall be due, not on the Initial Purchase Date, but
rather on the Initial Purchase Funding Date and shall be the excess of (a) the
Initial Purchase Price minus (b) One Hundred Thousand Dollars ($100,000), and
the Purchaser shall deliver to the Distributor on the Initial Purchase Funding
Date an unsecured promissory note dated the Initial Purchase Date in the
principal amount of One Hundred Thousand Dollars ($100,000) payable on January
2, 1999 with simple interest at the rate of 7% per annum from and excluding the
date of the Initial Purchase through and including January 2, 1999, and the
Distributor hereby agrees to accept such cash payment and promissory note in
full payment of the Initial Purchase Price. Each Purchase Cut-Off Date shall be
the last Business Day of a calendar month.

            Section 2.04. SALES AND PURCHASES. (a) The parties to this Agreement
intend that the transaction contemplated by Section 2.01 shall be, and shall be
treated as, a purchase by the Purchaser and a sale by the Distributor of the
Purchased Portfolio Assets relating thereto, constituting a True Sale, and shall
not be treated as a lending transaction. The sale of Purchased 



                                       2



<PAGE>   85

Portfolio Assets by the Distributor hereunder shall be without recourse to the
Distributor, hereunder; it being understood that the Purchaser in making each
Purchase is relying on the representations, warranties and covenants of the
Distributor and other Sponsor Entities contained in the Master Agreement.

            (b) The parties agree, to the fullest extent they may lawfully do
so, that the Purchase Price for the purchase and sale of the Purchased Portfolio
Assets relating thereto pursuant to this Agreement represents reasonably
equivalent value for the transfer of the same by the Distributor to the
Purchaser pursuant to this Agreement.

            Section 2.05. RECORDING OF SALES AND TRANSFERS. In connection with
the sale and conveyance of Purchased Portfolio Assets pursuant to this
Agreement, the Distributor shall indicate on its books and records that all such
Purchased Portfolio Assets have been sold or conveyed to the Purchaser. In
addition, the Distributor shall not carry as its assets any Purchased Portfolio
Assets sold to the Purchaser on its accounting records, and the Distributor
agrees that all such Purchased Portfolio Assets have been and will be, as
contemplated by the terms of this Agreement, transferred and sold to the
Purchaser and carried on the Purchaser's accounting records.

            Section 2.06. PURCHASER'S COLLECTION RIGHTS. The Purchaser has
appointed the Program Servicer Agent to, on the Purchaser's behalf, and pursuant
to the Program Servicer Agent Agreement, the Program Servicer Agent has agreed
to, take all actions it considers reasonable and in accordance with the Program
Servicer Agent Agreement to collect from the respective Companies and Funds all
payments in respect of the Purchased Portfolio Assets as and when the same shall
become due. The Distributor hereby irrevocably authorizes and empowers the
Purchaser and the Program Servicer Agent, on behalf of the Purchaser, to demand,
sue for, collect and receive payment of any funds due with respect to the
Purchased Portfolio Assets in the name of the Distributor, if required in the
good faith judgment of the Purchaser or the Program Servicer Agent; PROVIDED,
HOWEVER that so long no Event of Termination shall have occurred and be
continuing, the Purchaser and the Program Servicer Agent shall provide the
Distributor with at least ten (10) Business Days' prior notice before commencing
any such action.

            Section 2.07. CONTINUING OBLIGATIONS. Notwithstanding any other
provision of this Agreement, to the extent that any obligation of the
Distributor under, pursuant to and in connection with the Purchased Portfolio
Assets remains unperformed or executory, the Distributor hereby appoints the
Program Servicer Agent, on its behalf but for the benefit of the Purchaser, to
perform such obligation to the same extent as if the purchase and sale
contemplated hereby had not taken place, and the Purchaser shall not be required
or obligated in any manner to perform or fulfill any of the obligations of
Distributor under, pursuant to or in connection with any Purchased Portfolio
Assets.

            Section 2.08. FURTHER ASSURANCES. The Distributor agrees to do such
further acts and things, and to execute and deliver to the Purchaser such
additional assignments, agreements, powers and instruments, as are reasonably
required by the Purchaser to carry into effect the purposes of this Agreement or
to better assure and confirm unto the Purchaser its rights, power and remedies
hereunder.

            For valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, and to induce the Purchaser to purchase the Purchased
Portfolio Assets hereunder, the Distributor hereby grants to the Purchaser, in
order to secure the Purchaser's rights under this Agreement in the event the
purchase of any Purchased Portfolio Assets by the Purchaser is recharacterized
as a loan from the Purchaser to the Distributor, a security interest in any
right, title and interest in and to such Purchased Portfolio Assets, whether now
owned or hereafter acquired, that remain property of the Distributor's estate
notwithstanding this Agreement.

Agreement.

and interest in, to and under this Agreement, including all of the Purchaser's
right, title and interest in and to Purchased Portfolio Assets may be assigned
as contemplated by the Master Agreement without the consent of the Distributor.

            Section 4.04. GOVERNING LAW. THIS AGREEMENT SHALL BE DEEMED TO BE A
CONTRACT MADE UNDER THE LAWS OF THE STATE OF NEW YORK AND FOR ALL PURPOSES SHALL
BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF SAID STATE, WITHOUT

            Section 4.05. SEVERABILITY OF PROVISIONS. Any provisions of this
Agreement which are prohibited or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the

servicer agent hereunder, the "PROGRAM SERVICER AGENT").

                             W I T N E S S E T H:

            WHEREAS, the Distributor, the Purchaser and the Program
Administrator are parties to that certain Pioneer Program Master Agreement dated
as of the date hereof with the "Parent," "Advisor" and "Collection Agent" as
defined therein (the "MASTER AGREEMENT") pursuant to which the Purchaser shall
purchase the Purchased Portfolio Assets (defined as hereinafter provided) upon
the terms and subject to the conditions described therein; and

            WHEREAS, it is a condition precedent in the Master Agreement that
the parties hereto enter into this Agreement;

            NOW, THEREFORE, in consideration of the premises, the mutual
covenants and agreements herein contained, and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:

                                    ARTICLE I

                       RULES OF CONSTRUCTION; DEFINITIONS

            Section 1.01.  RULES OF CONSTRUCTION.  The rules of construction
set forth in Schedule X to the Master Agreement shall be applied to this
Agreement.

            Section 1.02.  DEFINITIONS.  Capitalized terms not expressly
defined herein which are defined in Schedule X to the Master Agreement, shall
have the same meanings herein as in said Schedule.

                                   ARTICLE II

               ADMINISTRATION AND SERVICING OF PORTFOLIO ASSETS

            Section 2.01. DUTIES OF THE PROGRAM SERVICER AGENT. The Program
Servicer Agent's duties shall be: (i) to exercise all of the Distributor's and
the Purchaser's rights (including, to the extent acquired by the Purchaser, all
of the Distributor's rights) under the Distributor's Contracts, the Distribution
Plans, the Prospectuses, each Irrevocable Payment 






<PAGE>   97

Instruction and at law or equity to cause each Fund (or in respect of any Fund
which constitutes a portfolio, to cause the related Company in respect of such
Fund) to pay to the Program Collection Account when due all amounts due from
such Fund or its shareholders in respect of outstanding shares of the Fund which
relate to Purchased Portfolio Assets relating to each Fund; (ii) the recording
of all Portfolio Assets due under or in connection with each Fund; (iii)
investigating delinquencies; (iv) responding to inquiries of the Purchaser and
the Program Administrator; (v) enforcing the Purchaser's rights with respect to
the Purchased Portfolio Assets relating to each Fund; (vi) accounting for
Program Collections in respect of the Purchased Portfolio Assets relating to

and authority, acting alone, to do any and all things in connection with such
management, servicing, administration, performance and collection which it deems
necessary or appropriate but in no case shall the Program Servicer Agent take
any action under this Section 2.01 inconsistent with the provisions of the
Master Agreement, the Program Collection Agency Agreement or which gives rise to
the reasonable possibility of an Adverse Effect. The Program Servicer Agent has
no right to receive payments on account of Purchased Portfolio Assets for its
own account. The Program Servicer Agent is required to take such actions as may
be necessary or advisable to collect Purchased Portfolio Assets, but is not
authorized to extend, modify or amend any Purchased Portfolio Assets without the
prior consent of the Program Administrator and the Purchaser.

            Section 2.02. APPOINTMENT OF THE PROGRAM SERVICER AGENT AS AGENT FOR
THE PURCHASER. The Purchaser hereby appoints Pioneer Funds Distributor, Inc. as

Program Servicer Agent, upon the Program Servicer Agent's written request, with
such powers of attorney and other documents reasonably necessary to enable the
Program Servicer Agent to carry out its servicing and administrative duties
hereunder.

            Section 2.03. CONTINUING COVENANTS OF THE PROGRAM SERVICER Agent.
The Program Servicer Agent hereby covenants and agrees that it shall at all
times:

            (a) punctually perform and observe all of its obligations and
agreements contained herein;

            (b) carry out its obligations hereunder in accordance with all
Applicable Laws (except where the failure to comply with Applicable Laws could
not reasonably be expected to give rise to an Adverse Effect) and with due care,
using at least the degree of skill, care and attention followed by responsible
institutions servicing comparable mutual fund distribution plans and
distribution agreements and in accordance with the terms of this Agreement and
the Program Servicing Procedures in effect from time to time and with
instructions received from the Purchaser;


                                       2


<PAGE>   98

            (c) do nothing (in its capacity as Program Servicer Agent) which
could reasonably be expected to (i) impair or otherwise adversely affect the
rights of the Purchaser in any Purchased Portfolio Assets or under any Program
Document or the collectibility of the Purchased Portfolio Assets relating to any
Fund, or (ii) otherwise give rise to an Adverse Effect;

            (d) provide such information to the Program Administrator as it may
reasonably request from time to time with respect to the Portfolio Assets or
which is otherwise reasonably necessary, in the reasonable judgment of the
Program Administrator, to make any determination in connection with any consent,
waiver or other action which may be given or taken under or in connection with
this Agreement or the other Program Documents; and

            (e) keep in full force and effect its existence and good standing
under the laws of the jurisdiction of its incorporation and obtain and preserve
its qualification to do business as a foreign corporation in each jurisdiction
in which the nature of its business or the performance of its obligations under
this Agreement requires such qualification, except to the extent that the
failure to so qualify could not reasonably be expected to have an Adverse
Effect.

            Section 2.04. NO OFFSET. The obligations of the Program Servicer
Agent under this Agreement shall not be subject to any defense, counterclaim or
right of offset which the Distributor (as Program Servicer Agent or otherwise)
has or may have against the Purchaser, the Program Administrator or any other
Person, whether in respect of this Agreement, any other Program Document, the
Portfolio Assets relating to any Fund or otherwise.

                                   ARTICLE III

                        INVESTOR REPORTS; RECORDKEEPING;
                                  COMPENSATION

            Section 3.01. INVESTOR REPORTS. Monthly on or prior to the 10th day
of each calendar month, the Program Servicer Agent shall provide the Program

electronic files related to each Investor Report will be transmitted to the
Program Administrator on or prior to the 5th Business Day of each calendar month
in accordance with the Program Servicing Procedures.

            Section 3.02. RECORDKEEPING. The Program Servicer Agent shall
maintain accurate records with respect to the Portfolio Assets relating to each
Fund and shall retain all information relating directly to, or maintained in
connection with, the servicing of such Portfolio Assets, at the offices of the
Program Servicer Agent, and shall give the Purchaser, the Program Administrator,
any Permitted Designees or any of their agents or representatives access to all
such information at all reasonable times, on reasonable notice during business
hours. The Program Servicer Agent shall, at the reasonable request of the
Purchaser or the Program Administrator, deliver to them all such information
which is reasonably necessary for evaluating the servicing of the Portfolio

            Section 3.03. SERVICING EXPENSES AND COMPENSATION. The Program

performance of its duties hereunder and will not be entitled to reimbursement
for any such expenses or any compensation for its services hereunder.

                           THE PROGRAM SERVICER AGENT

            Section 4.01. PROGRAM SERVICER AGENT NOT TO RESIGN. The Program
Servicer Agent shall not resign from the duties and obligations hereby imposed
upon it except upon a determination that by reason of a change in Applicable Law
(i) the continued performance by the Program Servicer Agent of its duties
hereunder would cause it to be in violation of such Applicable Law, and (ii)
there is no reasonable action which the Program Servicer Agent could take to
comply with Applicable Law. Such a determination to that effect shall be
evidenced by a certificate of an executive officer of the Program Servicer Agent
accompanied by an opinion of outside counsel to the Program Servicer Agent
reasonably satisfactory to the Purchaser and the Program Administrator with
respect to the matters described in clause (i) of the preceding sentence.

            Section 4.02. NO ASSIGNMENT. The Program Servicer Agent may not
assign this Agreement or any of its rights, powers, duties or obligations
hereunder.

            Section 4.03. DELEGATION OF DUTIES. The Program Servicer Agent may
execute any of its duties under this Agreement by or through an agent with the
prior written consent of the Program Administrator, which consent shall not be
unreasonably withheld or delayed; PROVIDED, HOWEVER, that the Program Servicer
Agent's exercise of any such duties through any such agent shall not in any way
affect or limit its liabilities under this Agreement.

                                    ARTICLE V

             REMOVAL FOR CAUSE; SUCCESSOR PROGRAM SERVICER AGENT

            Section 5.01. REMOVAL FOR CAUSE. The Purchaser or the Program
Administrator for Cause may remove Pioneer Funds Distributor, Inc. as Program
Servicer Agent under this Agreement and all of the rights and powers of the
Program Servicer Agent hereunder shall terminate on five (5) Business Days'
prior written notice to the Program Servicer Agent, it being understood that
such removal and termination shall not operate to terminate any of the Program
Servicer Agent's obligations under this Agreement other than its obligation to
perform the duties set forth in Articles II and III hereof after the date of
such termination. Upon such termination of the Program Servicer Agent's rights
and powers, all rights and powers of the Program Servicer Agent hereunder with
respect to the Portfolio Assets relating to each Fund will immediately vest in
the Program Administrator or such other Permitted Entity (as defined in Section
5.02) as the Program Administrator shall designate, and the Program
Administrator or such Permitted Entity 


                                       4

shall be authorized and empowered to execute and deliver, on behalf of the
Program Servicer Agent, as attorney-in-fact or otherwise, all documents and
other instruments and to do all other things which the Purchaser or the Program
Administrator believes to be necessary or appropriate to effect such vesting,
subject, however, to the provisions of applicable law. The term "CAUSE" as used
herein shall mean: (i) the failure, in any material respect, of the Program
Servicer Agent to perform obligations under this Agreement, fully and in a
timely manner after being notified of such failure by the Program Administrator;
or (ii) the occurrence of an event of the type specified in clauses (e), (f),
(h), (i) or (k) of the definition of Event of Termination with respect to the
Program Servicer Agent.

            Section 5.02. APPOINTMENT OF SUCCESSOR PROGRAM SERVICER AGENT. (a)
Within thirty (30) days after the time the Program Servicer Agent delivers a
notice of resignation pursuant to Section 4.01 or is removed pursuant to Section
5.01, the Program Administrator shall appoint a successor servicer (the
"SUCCESSOR"), which may be the Program Administrator, any Affiliate of the
Purchaser or the Program Administrator or such other Person reasonably
satisfactory to the Program Administrator (each a "PERMITTED ENTITY").

            (b) Any such Successor shall have the following additional rights:
(i) to have its agents, employees and representatives enter upon the premises of
the Program Servicer Agent and the other Sponsor Entities during normal business
hours upon reasonable notice, and (ii) to perform at such premises all of the
functions necessary to be performed in accordance with the terms hereof for
fulfillment of its obligations hereunder including, but not limited to,
performance of all necessary accounting functions, bookkeeping functions,
notification and reporting functions and to deal in all other respects with the
Portfolio Assets relating to each Fund to the extent required to be performed by
the Program Servicer Agent hereunder. The Purchaser and the Program
Administrator (or their respective designees) shall be authorized and empowered
through their respective officers, directors, agents and employees to execute on
behalf of the Program Servicer Agent all checks, bills, drafts, deposits and
other bank documents or other instruments as may be necessary or appropriate to
effect the foregoing.

            Section 5.03. NO EFFECT ON OTHER PARTIES. Upon any termination of
the rights and powers of the Program Servicer Agent pursuant to Section 4.01 or
Section 5.01 hereof, or upon any appointment of a Successor, all the rights and
powers of the Purchaser and the Program Administrator hereunder will remain
unaffected by the termination or appointment and will remain in full force and
effect.

            Section 5.04. RIGHTS CUMULATIVE. The rights and remedies conferred
upon or reserved to the Purchaser and the Program Administrator in this
Agreement, the Master Agreement, and the other Program Documents are cumulative,
and none is intended to be exclusive of another. No delay or omission in
insisting upon the strict observance or performance of any provision hereof or
of the Master Agreement, or any other Program Document, or in exercising any
right or remedy hereunder or thereunder, will be construed as a waiver or
relinquishment of that provision or will impair such right or remedy. Every
right and remedy may be exercised from time to time and as often as deemed
expedient.

                  Portion, PLUS, the Purchaser's CDSC Portion, PLUS the
                  Purchaser's Investment Earnings, LESS

                  determined in accordance with Section 4.03(b), shall be
                  transferred to the Purchaser's Remittance Account; and

                  (iv)  an amount equal to the result of:

                        (A) the sum of the Distributor's Asset Based Sales
                  Charge Portion, PLUS, the Distributor's CDSC Portion, plus the

                  distributed pursuant to clauses (i) and (ii) above, as

        shall be transferred to the Distributor's Remittance Account.

            (b) (i) The amount of funds applied by the Collection Agent in
accordance with Section 4.03(a)(i) on any Monthly Settlement Date shall be
allocated among the Purchaser and the Distributor in the proportion that Program
Collections and Related Collections deposited in the Program Collection Account
since the immediately preceding Monthly Settlement Date are allocated among each
thereof on the Monthly Settlement Date in question; and

                  (ii) The amount of funds applied by the Collection Agent in
accordance with Section 4.03(a) (ii) on any Monthly Settlement Date shall be
allocated among the Purchaser and the Distributor in the proportion that Program
Collections and Related Collections deposited in the Program Collection Account
since the immediately preceding Monthly Settlement Date are allocated to each on
the Monthly Settlement Date in question; PROVIDED, HOWEVER, that special





                                       5




<PAGE>   113

allocations of Program Costs will be made by the Program Administrator if such
costs are related solely to Portfolio Assets owned by the Purchaser or the
Distributor.

            (c) (i) As used in this Agreement the term "PURCHASER'S INVESTMENT
EARNINGS" shall mean on any Monthly Settlement Date, an amount equal to the
product of (A) the result of (x) the Investment Earnings, if any, minus (y) the
Investment Losses, if any, and (B) a fraction, expressed as a percentage, the
numerator of which is the Purchaser's Portion (determined without regard to
clause (iii) of the definition thereof) of the Program Collections and Related
Collections which were deposited in the Program Collection Account since the
immediately preceding Monthly Settlement Date and the denominator of which is
the total amount of Program Collections and Related Collections which were
deposited in the Program Collection Account since the immediately preceding
Monthly Settlement Date.

            (ii) As used in this Agreement the term "DISTRIBUTOR'S INVESTMENT
EARNINGS" shall mean on any Monthly Settlement Date, an amount equal to the
product of (a) the result of (x) the Investment Earnings, if any, minus (y) the
Investment Losses, if any, and (b) a fraction, expressed as a percentage, the
numerator of which is the Distributor's Portion (determined without regard to
clause (iii) of the definition thereof) of Program Collections and Related
Collections which were deposited in the Program Collection Account since the
immediately preceding Monthly Settlement Date and the denominator of which is
the total amount of Program Collections and Related Collections which were
deposited in the Program Collection Account since the immediately preceding
Monthly Settlement Date.

            (d) For purposes of determining the amounts to be distributed
pursuant to Section 4.03(a), the Purchaser hereby authorizes the Collection
Agent to conclusively rely upon the written statements of the Authorized
Representative of the Program Administrator setting forth the calculations of
such amounts, and the Distributor hereby consents thereto (which notice or
statements shall set forth in reasonable detail the computation of such
amounts). Unless such written statement is received by the Collection Agent on
or prior to 12:00 noon (New York City time) on the Business Day funds are to be
distributed under Section 4.03(a), the Collection Agent shall use its reasonable
efforts to, but shall not be obligated to, distribute such amounts on such day;
PROVIDED, HOWEVER, that if such certificate or statement is received by the
Collection Agent after 12:00 noon (New York City time) on any day on or after
the date that such funds were to be distributed under Section 4.03(a), it shall
in any event distribute such funds not later than the next succeeding Business
Day after receipt of such certificate or statement; and PROVIDED, FURTHER, that
if such certificate or statement is received by the Collection Agent prior to
the close of business (New York City time) on the day prior to the day on which
funds were to be distributed under Section 4.03(a) (each such day on which funds
are to be distributed, the "DISTRIBUTION DATE"), it shall in any event
distribute such funds not later than 12:00 noon (New York City time) on the
Distribution Date.

            Notwithstanding the foregoing, if an Authorized Representative of
the Distributor or the Purchaser shall have certified in writing that the
computation of any amount in respect of the Distributor's Portion or the
Purchaser's Portion under Section 4.03(a) is not in conformity with the
mechanics for calculating any such amount set forth in this Agreement or any
other Program Document (which certification shall set forth in reasonable detail
the Distributor's or the 




                                       6




<PAGE>   114

Purchaser's, as the case may be, calculation of such amount, the nature of the
alleged error made and the amount of such discrepancy), the Collection Agent
shall not distribute the amount of the discrepancy stipulated in such
certificate until the Distributor and the Purchaser shall have agreed upon how
such amount should be properly distributed or a court shall have made a
determination concerning the amounts properly distributable in respect thereto.

            Each of the Distributor and the Purchaser agrees that it shall not
send the certificate specified in the immediately preceding sentence unless it
reasonably believes that the computation of the Distributor's Portion or the
Purchaser's Portion, as the case may be, was not in conformity with the
provisions of this Agreement and the Master Agreement. The Collection Agent
shall not be liable for any application of the moneys and other cash proceeds
pursuant to Section 4.03(a) made in accordance with any certificate or written
direction delivered pursuant to this Section 4.03(d) or otherwise made in
accordance with the second preceding sentence; PROVIDED, HOWEVER, that no
application of the moneys and other cash proceeds by the Collection Agent in
accordance with any certificate or other written direction delivered or made
pursuant to this Section 4.03(d) shall be deemed to restrict or limit the right
of any party to contest with the purported obligee the amount set forth in such
certificate or other written direction. In no event shall the Collection Agent
be obligated to make any application or distribution of funds in the Program
Collection Account in the absence of such certificate or written direction. For
purposes of this Agreement, the term "AUTHORIZED REPRESENTATIVE" shall mean any
individual at the time designated to act on behalf of the Distributor, the
Purchaser or the Program Administrator, as the case may be, such designation to
be evidenced by a written certificate (an "AUTHORIZED REPRESENTATIVE
CERTIFICATE") (i) furnished on the date hereof and from time to time hereafter
by the Distributor, the Purchaser or the Program Administrator, as the case may
be, to the Collection Agent containing the name, title and specimen signature of
each such individual, and (ii) executed on behalf of the Distributor, the
Purchaser or the Program Administrator, as the case may be, by the President,

Collection Agent has received a subsequent Authorized Representative
Certificate, the Collection Agent shall be entitled to rely conclusively on the
last such Authorized Representative Certificate delivered to it hereunder for
the purpose of determining the Authorized Representatives of the Distributor,
the Purchaser or the Program Administrator, as the case may be.

            (e) The Collection Agent shall (subject to Section 4.03(d)) upon its
receipt of an Allocation Notice (with a copy to the other parties hereto) remit

having maturities which shall not extend beyond the next following Monthly
Settlement Date (each such investment, a "CASH EQUIVALENT") and which
constitute:

             (i) marketable direct obligations issued or unconditionally and
      fully guaranteed by the United States of America or issued by any agency
      thereof;

      States of America or any political subdivision of any such state or any
      public instrumentality thereof and having as at any date of determination
      the highest rating obtainable from Standard & Poor's;

           (iii) commercial paper issued by any corporation (other than an
      Affiliate of the Seller) organized and existing under the United States of
      America and having as at any date of determination the highest rating
      obtainable from Standard & Poor's;

            (iv) certificates of deposit issued by commercial banking
      institutions that are members of the Federal Reserve System, each having
      as at any date of determination combined capital and surplus of not less
      than $500,000,000, and the commercial paper of other short-term unsecured
      debt obligations of which, as at any date of determination, have the
      highest rating obtainable from Standard & Poor's ("PERMITTED BANKS"); and

             (v) investments in money market funds having a rating of "AAAm" or

      the Collection Agent or any of their respective Affiliates is investment
      manager or advisor).

In the absence of specific written instructions by an Authorized Representative
of the Program Administrator, the Collection Agent shall, in accordance with
this Section 4.04, invest the Deposited Collection Funds in such Cash
Equivalents described in clause (v) above. All such Cash Equivalents and the
interest and income received thereon and the net proceeds realized on the sale
or redemption thereof shall be deemed to be to the credit of the Program
Collection Account.

            (b) The Collection Agent may, without requirement of instructions
from the Program Administrator, take such actions as are reasonably necessary to
realize the proceeds of any such Cash Equivalent that are held to the stated
maturity thereof. The Collection Agent may, at the written direction of the
Program Administrator, liquidate Cash Equivalents from time to time to the
extent necessary to make payments pursuant to Section 4.03 hereof. None of the
Collection Agent, the Purchaser, the Distributor or the Program Administrator
shall have recourse to any other party hereto for any loss resulting from the
investment performance of any investment or reinvestment of moneys made in
accordance with the provisions of this Section or from the sale or liquidation
of such Cash Equivalents.

the Purchaser, and the Distributor a separate account as a sub-account of the
Program Collection Account referred to as: (i) the "PURCHASER CDSC SUB-ACCOUNT,"
in the case of the Purchaser; and (ii) the "DISTRIBUTOR CDSC SUB-ACCOUNT," in

a portion of such deposit in the CDSC Sub-account for each of the Purchaser and
the Distributor equal to a percentage of the total amount of such deposit equal
to the Purchaser's CDSC Portion or Distributor's CDSC Portion, as the case may
be, for the Monthly Settlement Date immediately preceding such deposit, all in
accordance with the written direction of an Authorized Representative of the
Program Administrator.

            (c) If as of any Monthly Settlement Date the Program Administrator
determines that the amount on deposit in any CDSC Sub-account includes a portion
of the CDSC Portion for such Monthly Settlement Date of a party other than the
party for whom such CDSC Sub-account was established, the Collection Agent
shall, at the written direction of the Program Administrator, transfer such
amount to the proper CDSC Sub-account.

            (d) On each Monthly Settlement Date, the amounts on deposit in the
CDSC Sub-accounts which are required to be distributed to the Purchaser or the
Distributor shall be paid to such party directly from the CDSC Sub-account
established for such party in accordance with the provisions of Section 4.03.

Master Collection Agent (the "COLLATERAL AGENT"), certain Secured Parties
parties thereto and the Placement Trust parties thereto (the "PURCHASER

Agent as the Collateral Agent's agent for purposes of perfecting the Collateral

perfecting the indenture trustee's security interest created by the relevant
indenture in the interest of the Purchaser in the Program Collection Account and
in the Deposited Funds deposited therein. The Collection Agent accepts such

Agreement.

            Section 5.03. DELEGATION OF DUTIES. Subject to Article VI hereof,

Agreement. The Collection Agent may, however, execute any of its duties under
this Agreement by or through its officers, directors, employees, attorneys,
custodians, nominees or agents; PROVIDED, HOWEVER, that no such delegation of
duties shall limit or otherwise affect the liability of the Collection Agent for

matters pertaining to its duties under this Agreement.

            Section 5.04. RELIANCE BY COLLECTION AGENT. The Collection Agent and
its officers, directors, employees, attorneys, nominees and agents shall be
entitled to conclusively rely and shall be fully protected in relying on any
writing, resolution, notice, consent, certificate, affidavit, letter, cablegram,

reasonably believed by it or them to be genuine and correct and to have been
signed or made by the proper Person and, with respect to legal matters, upon
opinions of counsel selected by the Collection Agent.

            Section 5.05. COLLECTION AGENT IN ITS INDIVIDUAL CAPACITY. The
Collection Agent may accept deposits from, act as trustee under indentures of,
and generally engage in any kind of business with, the Purchaser, the Program
Administrator, the Distributor, any other party to any Program Document, any of
their respective Affiliates and any other Person who may do business with or own
securities of any of the foregoing, all as if the Collection Agent were not the
Collection Agent hereunder and without any duty to account therefor to the
Purchaser, the Program Administrator or the Distributor.

            Section 5.06. LIMITATION ON LIABILITY, ETC. Neither the Collection
Agent, nor any of its directors, officers, employees, custodians, nominees or
agents, shall be liable for any action taken or omitted to be taken by it or
them hereunder or in connection herewith, except for its or their gross
negligence or willful misconduct; nor shall the Collection Agent be responsible
for 



                                       10


<PAGE>   118

the validity, effectiveness, value, sufficiency or enforceability against the
Purchaser, the Program Administrator or the Distributor of this Agreement or any
other Program Document furnished pursuant hereto or in connection herewith.
Without limiting the generality of the foregoing, the Collection Agent: (i)
except as expressly provided in this Agreement or any other Program Document,
makes no warranty or representation, and shall not be responsible to the
Purchaser, the Program Administrator or the Distributor for any statements,
warranties or representations made in or in connection with this Agreement or
any such Program Document by any such Person; and (ii) shall not have any duty
to ascertain or to inquire as to the performance or observance of any of the
terms, covenants or conditions of this Agreement or any other Program Document
on the part of the Purchaser, the Program Administrator or the Distributor. No
implied covenant or obligation shall be read into this Agreement against the
Collection Agent. The Collection Agent shall not be compelled to do any act not
expressly set forth in this Agreement or to take any action towards the
enforcement of the powers hereby created or to prosecute or defend any suit in
respect hereof unless indemnified to its reasonable satisfaction against loss,
cost, liability and expense. The Collection Agent shall not have or be deemed to
have any trust relationship with the Purchaser, the Program Administrator or the

                           SUCCESSOR COLLECTION AGENT;
                       QUALIFICATIONS OF COLLECTION AGENT

            Section 6.01. SUCCESSOR COLLECTION AGENT. The Collection Agent
acting hereunder may resign at any time upon thirty (30) days prior written
notice to the Purchaser, the Program Administrator and the Distributor, and may
be removed at any time with or without cause by an instrument in writing duly
executed by the Purchaser and the Program Administrator. Subject to the
provisions of Section 6.02, the Program Administrator shall have the right to
appoint a successor to the Collection Agent which shall be such other bank or
financial institution selected by the Program Administrator and reasonably
satisfactory to the Purchaser and the Distributor upon any such resignation or
removal, by an instrument of substitution complying with the requirements of
Applicable Law, or, in the absence of any such requirements, without other
formality than appointment and designation in writing. Upon the making and
acceptance of such appointment, the execution and delivery by such successor
Collection Agent of a ratifying instrument pursuant to which such successor
Collection Agent agrees to assume the duties and obligations imposed on the
Collection Agent by the terms of this Agreement, and the delivery to such
successor Collection Agent of the Deposited Collection Funds and documents and
instruments then held by the retiring Collection Agent, such successor
Collection Agent shall thereupon succeed to and become vested with all the
estate, rights, powers, remedies, privileges, immunities, indemnities, duties
and obligations hereby granted to or conferred or imposed upon the Collection
Agent named herein, and one such appointment and designation shall not exhaust
the right to appoint and designate further successor Collection Agents
hereunder. No Collection Agent shall be discharged from its duties or
obligations hereunder the Collection Deposited Funds and documents and
instruments then held by such Collection Agent shall have been transferred or
delivered to the successor Collection Agent for 



                                       11


<PAGE>   119

deposit in the new Program Collection Account, as applicable, and until such
retiring Collection Agent shall have executed and delivered to the successor
Collection Agent appropriate instruments substituting such successor Collection
Agent as attorney-in-fact of the Purchaser, the Program Administrator and the
Distributor for purposes of this Agreement as contemplated by Section 2.02. If
no successor Collection Agent shall be appointed, as aforesaid, or, if
appointed, shall not have accepted its appointment, within thirty (30) days
after resignation or removal of the retiring Collection Agent then, subject to
the provisions of this Section 6.01, the Collection Agent may appoint a
successor Collection Agent reasonably satisfactory to the Purchaser, the Program
Administrator and the Distributor. Each such successor Collection Agent shall
provide the Purchaser, the Program Administrator and the Distributor with its
address, telephone and facsimile numbers, to be used for purposes of Section
8.02 hereof, in a notice complying with the terms of said Section.
Notwithstanding the resignation or removal of any Collection Agent hereunder,
the provisions of this Agreement shall continue to inure to the benefit of such
Collection Agent in respect of any action taken or omitted to be taken by such
Collection Agent in its capacity as such while it was Collection Agent under
this Agreement. No Collection Agent shall be liable by reason of any act or
omission of any successor Collection Agent.

            Section 6.02. QUALIFICATIONS OF COLLECTION AGENT. Any Collection
Agent at any time acting hereunder must at all times be an "Eligible
Institution," as hereinafter defined. For purposes of this Section 6.02, the
term "Eligible Institution" shall mean any branch of a depository institution or
trust company organized under the laws of the United States, any state thereof
or the District of Columbia (or any branch of a foreign bank), which (i) has
either (A) a long-term unsecured debt rating of "AA" (or the equivalent) or
better by Standard & Poor's or (B) a certificate of deposit rating of "A-1" by
Standard & Poor's, or is otherwise acceptable to Standard & Poor's and (ii) has
total capital and surplus of at least $100,000,000.

            Section 7.01. PAYMENT OF EXPENSES AND TAXES. The Distributor shall
(a) to the extent not otherwise paid pursuant to this Agreement or the Master
Agreement, pay or reimburse the Collection Agent for (i) all the reasonable
out-of-pocket costs and expenses (including the fees and disbursements of
counsel) incurred by the Collection Agent in connection with the preparation and
execution of this Agreement; (ii) all reasonable out-of-pocket costs and
expenses (other than fees and disbursements of counsel) incurred by the
Collection Agent in connection with any amendment, supplement or modification to
this Agreement and any other documents prepared in connection herewith or
therewith, and the consummation of the transactions contemplated hereby and
thereby; and (iii) the reasonable fees and disbursements of counsel to the
Collection Agent in connection with clause (ii); (b) to the extent not otherwise
paid pursuant to this Agreement or the Master Agreement, pay or reimburse the

connection with the enforcement or preservation of any rights under this
Agreement, and any such other documents, including, without limitation,
reasonable fees and disbursements of counsel to the Collection Agent, (c) to the

the Collection Agent, and its respective directors, officers, employees,
custodians, nominees, agents and representatives, harmless from, any and all
recording and filing fees and any and all liabilities with respect to, or
resulting from any delay in paying, stamp and other taxes, if any, which may be
payable or determined to be payable by the Collection Agent in connection with
the execution and delivery of, or consummation of any of the transactions
contemplated by, or any amendment, supplement or modification of, or any waiver
or consent under or in respect of, this Agreement, and any such other documents,
and (d) pay, indemnify, and hold the Collection Agent, and its directors,
officers, employees, custodians, nominees, agents and representatives, harmless
from and against any and all other liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursement of any
kind or nature whatsoever with respect to the enforcement, performance and
administration of this Agreement, the other Program Documents and any such other
documents contemplated hereby or thereby (all the foregoing, collectively, the
"INDEMNIFIED LIABILITIES"); PROVIDED, HOWEVER, that neither the Distributor, the
Purchaser or the Program Administrator shall have any obligation hereunder with
respect to the Collection Agent's ordinary administrative costs, or any
Indemnified Liabilities arising from (i) the breach by the Collection Agent of
any representation, warranty or covenant expressly set forth in this Agreement
or (ii) the gross negligence or willful misconduct of the Collection Agent.

            Section 7.02. FEES. The Collection Agent shall be paid a fee at the
rate of $6,000 per annum payable in equal installments in arrears monthly on
each Monthly Settlement Date during the term of this Agreement from Deposited
Collection Funds in the Program Collection Account in accordance with Section
4.03; PROVIDED, that if there are insufficient funds in the Program Collection
Account to satisfy the amounts payable on any Monthly Settlement Date, the
Distributor shall pay the Collection Agent any shortfall on such Monthly
Settlement Date.

                                  ARTICLE VIII

supplement, termination or waiver of this Agreement shall be effective unless
the same shall be in writing and signed by the Purchaser, the Program
Administrator, the Collection Agent and the Distributor. Any waiver of any
provision of this Agreement, and any consent to any departure by any party to
this Agreement from the terms of any provision of this Agreement, shall be
effective only in the specific instance and for the specific purpose for which
given. No notice to or demand on any party to this Agreement in any case shall
entitle such party to any other or further notice or demand in similar or other
circumstances.

            Section 8.02. NOTICES. All notices, demands, instructions and other
communications required or permitted to be given to or made upon any party
hereto shall be given or made in accordance with Section 8.03 of the Master
Agreement.

            Section 8.03. SEVERABILITY. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of 


                                       13


<PAGE>   121

such prohibition or unenforceability without invalidating the remaining
provisions hereof or affecting the validity or enforceability of such provision
in any other jurisdiction.

            Section 8.04. NO WAIVER; CUMULATIVE REMEDIES. No failure or delay on
the part of any party to this Agreement in exercising any right, power or
privilege hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any right, power or privilege hereunder preclude any other
or future exercise thereof or the exercise of any other right, power or
privilege. The remedies provided for herein are cumulative and are not exclusive
of any remedies that may be available to the Purchaser or the Program
Administrator at law or in equity.

            Section 8.05. TERMINATION. This Agreement shall terminate upon the
date that the Collection Agent receives written notification from the Program
Administrator that the Unamortized Gross Purchase Amount in respect of the
Purchased Portfolio Assets of each Fund has been reduced to zero; PROVIDED that

Agent receives written notification from the Program Administrator that all

Distributor may assign its rights to a portion of the amounts actually
distributable to the Distributor pursuant to Section 4.03 (the "ASSIGNED
PORTION") to an assignee unrelated to the Distributor in accordance with the
Master Agreement, and in the event that the Distributor shall secure a
commitment from an assignee to purchase such Assigned Portion, the parties
hereto agree to negotiate in good faith with a view to: (A) amending this
Agreement to: (1) permit such assignee to become a party to this Agreement; (2)
remove such Assigned Portion from the amounts distributable to the Distributor
pursuant to Section 4.03 and providing for such assignee to be entitled to
distributions pursuant to Section 4.03 in respect of the Assigned Portion, and
(B) executing and delivering a mutually satisfactory agreement among the Program
Administrator, the Purchaser, the Collection Agent and such assignee, specifying
their respective rights with respect to the Portfolio Assets.

Collection Agent, the Program Administrator, the Purchaser hereby acknowledge
that: (a) the Purchaser has assigned and will assign all of its rights under

____________ business trust (the "Trust")

                                   WITNESSETH

         WHEREAS, the Trust is engaged in business as an open-end, diversified,
management investment company and is registered under the Investment Company Act
of 1940, as amended (collectively with the rules and regulations promulgated
thereunder, the "1940 Act");

         WHEREAS, the Trust intends to distribute shares of beneficial interest
(the "Class B Shares") of the Trust in accordance with Rule 12b-1 promulgated by
the Securities and Exchange Commission under the 1940 Act ("Rule 12b-1"), and
desires to adopt this Class B Shares distribution plan (the "Class B Plan") as a
plan of distribution pursuant to such Rule;

         WHEREAS, the Trust desires that Pioneer Funds Distributor, Inc., a
Massachusetts corporation ("PFD") or such other persons as may be appointed
principal underwriter from time to time, provide certain distribution services
for the Trust's Class B Shares in connection with the Class B Plan (PFD and any
successor principal underwriter of the Trust's shares being referred to as an
"Underwriter");

         WHEREAS, the Trust has entered into an underwriting agreement (in a
form approved by the Trust's Board of Trustees in a manner specified in Rule
12b-1) with the Underwriter, whereby the Underwriter provides facilities and
personnel and renders services to the Trust in connection with the offering and
distribution of Class B Shares (the "Underwriting Agreement");

         WHEREAS, the Trust also recognizes and agrees that (a) the Underwriter
may retain the services of firms or individuals to act as dealers or wholesalers
(collectively, the "Dealers") of the Class B Shares in connection with the
offering of Class B Shares, (b) the Underwriter may compensate any Dealer that
sells Class B Shares in the manner and at the rate or rates to be set forth in
an agreement between the Underwriter and such Dealer and (c) the Underwriter may
make such payments to the Dealers for distribution services out of the fee paid
to the Underwriter hereunder, any deferred sales charges imposed by the
Underwriter in connection with the repurchase of Class B Shares, its profits or
any other source available to it;

         WHEREAS, the Trust recognizes and agrees that the Underwriter may
impose certain deferred sales charges in connection with the repurchase of Class
B Shares by the Trust, and the Underwriter may retain (or receive from the
Trust, as the case may be) all such deferred sales charges; and

         WHEREAS, the Board of Trustees of the Trust, in considering whether the
Trust should adopt and implement this Class B Plan, has evaluated such
information as it deemed necessary to an informed determination whether this
Class B Plan should be adopted and implemented and has considered such pertinent
factors as it deemed necessary to form the basis for a decision to use assets of
the Trust for such purposes, and has determined that there is a reasonable
likelihood that the adoption and implementation of this Class B Plan will
benefit the Trust and its Class B shareholders;

         NOW, THEREFORE, the Board of Trustees of the Trust hereby adopts this
Class B Plan for the Trust as a plan of distribution of Class B Shares in
accordance with Rule 12b-1, on the following terms and conditions:

         1.                (a) The Trust is authorized to compensate the
                  Underwriter for (1) distribution services and (2) personal and
                  account maintenance services performed and expenses incurred
                  by the Underwriter in connection with the Trust's Class B
                  Shares. Such compensation shall be calculated and accrued
                  daily and paid monthly or at such other intervals as the Board
                  of Trustees may determine.

                           (b) The amount of compensation payable to the
                  Underwriter during any one year for distribution services with
                  respect to Class B Shares shall be its Allocable Portion (as
                  defined in Section 14 below) of .75% of the Trust's average
                  daily net assets attributable to Class B Shares for such year
                  (the "Distribution Fee"). Notwithstanding anything to the
                  contrary set forth in this Distribution Plan or any
                  Underwriting Agreement, the Distribution Fee shall not be
                  terminated or modified (including a modification by change in
                  the rules relating to the conversion of Class B Shares into
                  Class A Shares of the Trust) with respect to Class B Shares
                  (or the assets of the Trust attributable to such Class B
                  Shares) either (x) issued prior to the date of any termination
                  or modification or (y) attributable to Class B Shares issued
                  through one or a series of exchanges of shares of another
                  investment company for which the Underwriter acts as principal
                  underwriter which were initially issued prior to the date of
                  such termination or modification or (z) issued as a dividend
                  or distribution upon Class B Shares initially issued or
                  attributable to Class B Shares issued prior to the date of any
                  such termination or modification (the "Pre-Amendment Class B
                  Shares") except:

                           Investment Company 1940 Act, the rules or regulations
                           under the Act, the Conduct Rules of the National
                           Association of Securities Dealers, Inc. (the "NASD"),
                           or an order of any court or governmental agency, in
                           each case enacted, issued or promulgated after
                           September 30, 1998,

                           (ii) in connection with a "Complete Termination" of
                           this Plan. For purposes of this Plan, a "Complete
                           Termination" shall have occurred if: (x) this Plan
                           and the distribution plan for Class B Shares of any
                           successor trust or fund or any trust or fund
                           acquiring substantially all of the assets of the
                           Trust (collectively, the "Affected Funds") is
                           terminated with respect to all Class B Shares of the
                           Trust and each Affected Fund then outstanding or
                           subsequently issued, (y) the payment by the Trust of
                           Distribution Fees with respect to all Class B Shares
                           of the Trust and each Affected Fund is terminated and
                           (z) neither the Trust nor any Affected Fund
                           establishes concurrently with or subsequent to such
                           termination of this Plan another class of shares
                           which has substantially similar characteristics to
                           the current Class B Shares of the Trust, including
                           the manner of payment and amount of contingent
                           deferred sales charge paid directly or indirectly by
                           the holders of such shares (all of such classes of
                           shares "Class B Shares"), or

                           (iii) on a basis, determined by the Board of
                           Trustees, including a majority of the Qualified
                           Trustees (as hereinafter defined), acting in good
                           faith, so long as from and after the effective date
                           of such modification or termination: (x) neither (1)
                           the Trust, (2) any Affected Fund nor (3) the
                           investment advisor or any other sponsor entity (or
                           their affiliates) of the Trust or any Affected Fund
                           pay, directly or indirectly, a fee, a trailer fee, or
                           expense reimbursement to any person for the provision
                           of personal and account maintenance services (as such
                           terms is used in the Conduct Rules of the NASD) to
                           the holder of Class B Shares of the Trust or any
                           Affected Fund (but the forgoing shall not prevent
                           payments for transfer agency or subaccounting
                           services), and (y) the termination or modification of

                           Class B Shares (as defined in Section 7) outstanding
                           from time to time of the Trust and all Affected
                           Funds.

                           (c) Distribution services and expenses for which an
                  Underwriter may be compensated pursuant to this Plan include,
                  without limitation: compensation to and expenses (including
                  allocable overhead, travel and telephone expenses) of (i)
                  Dealers, brokers and other dealers who are members of the NASD
                  or their officers, sales representatives and employees, (ii)
                  the Underwriter and any of its affiliates and any of their
                  respective officers, sales representatives and employees,
                  (iii) banks and their officers, sales representatives and
                  employees, who engage in or support distribution of the
                  Trust's Class B Shares; printing of reports and prospectuses
                  for other than existing shareholders; and preparation,
                  printing and distribution of sales literature and advertising
                  materials.

                           (d) The Underwriter shall be deemed to have performed
                  all services required to be performed in order to be entitled
                  to receive its Allocable Portion of the Distribution Fee, if
                  any, payable with respect to Class B Shares sold through such
                  Underwriter upon the settlement date of the sale of such Class
                  B Shares or in the case of Class B Shares issued through one
                  or a series of exchanges of shares of another investment
                  company for which the Underwriter acts as principal
                  underwriter or issued as a dividend or distribution upon Class
                  B Shares, on the settlement date of the first sale on a
                  commission basis of a Class B Share from which such Class B
                  share was derived. The Trust's obligation to pay an
                  Underwriter its Allocable Portion of the Distribution Fees
                  payable in respect of the Class B Shares shall be absolute and
                  unconditional and shall not be subject to dispute, offset,
                  counterclaim or any defense whatsoever, at law or equity,
                  including, without limitation, any of the foregoing based on
                  the insolvency or bankruptcy of such Underwriter. The
                  foregoing provisions of this Section 1(d) shall not limit the
                  rights of the Trust to modify or terminate payments under this
                  Class B Plan as provided in Section 1(b) with respect to
                  Pre-Amendment Class B Shares or Section 7 with respect to
                  Post-Amendment Class B Shares.

                           (e) The amount of compensation paid during any one
                  year for personal and account maintenance services and
                  expenses (the "Service Fee") shall be .25% of the Trust's
                  average daily net assets attributable to Class B Shares for
                  such year. As partial consideration for personal services
                  and/or account maintenance services provided by the
                  Underwriter to the Class B Shares, the Underwriter shall be
                  entitled to be paid any fees payable under this clause (e)
                  with respect to Class B Shares for which no dealer of record
                  exists, where less than all consideration has been paid to a
                  dealer of record or where qualification standards have not
                  been met.

                           (f) Personal and account maintenance services for
                  which the Underwriter or any of its affiliates, banks or
                  Dealers may be compensated pursuant to this Plan include,
                  without limitation: payments made to or on account of the
                  Underwriter or any of its affiliates, banks, other brokers and
                  dealers who are members of the NASD, or their officers, sales
                  representatives and employees, who respond to inquiries of,
                  and furnish assistance to, shareholders regarding their
                  ownership of Class B Shares or their accounts or who provide
                  similar services not otherwise provided by or on behalf of the
                  Trust.

                           (g) The Underwriter may impose certain deferred sales
                  charges in connection with the repurchase of Class B Shares by
                  the Trust and the Underwriter may retain (or receive from the
                  Trust as the case may be) all such deferred sales charges.

                           (h) The Trust has agreed in the Underwriting
                  Agreement to certain restrictions on the Trust's ability to
                  modify or waive certain terms of the Trust's Class B Shares or
                  the contingent deferred sales charge with respect to
                  Pre-Amendment Class B Shares.

                           (i) Appropriate adjustments to payments made pursuant
                  to clauses (b) and (d) of this paragraph 1 shall be made
                  whenever necessary to ensure that no payment is made by the
                  Trust in excess of the applicable maximum cap imposed on asset
                  based, front-end and deferred sales charges by Section 2830(d)
                  the Conduct Rules of the NASD.

         2.       The Trust understands that agreements between the Underwriter
and Dealers may provide for payment of fees to Dealers in connection with the
sale of Class B Shares and the provision of services to shareholders of the
Trust. Nothing in this Class B Plan shall be construed as requiring the Trust to
make any payment to any Dealer or to have any obligations to any Dealer in
connection with services as a dealer of the Class B Shares. The Underwriter
shall agree and undertake that any agreement entered into between the
Underwriter and any Dealer shall provide that such Dealer shall look solely to
the Underwriter for compensation for its services thereunder and that in no
event shall such Dealer seek any payment from the Trust.

         3.       Notwithstanding anything to the contrary in this Distribution
Plan or any Underwriting Agreement, the Underwriter may assign, sell or pledge
(collectively, "Transfer") its rights to its Allocable Portion of any
Distribution Fees under this Plan. Upon receipt of notice of such Transfer, the
Trust shall pay to the assignee, purchaser or pledgee (collectively with their
subsequent transferees, "Transferees"), as third-party beneficiaries, such
portion of the Distribution Fees


                                       -5-

payable to the Underwriter as provided in written instructions (the "Allocation
Instructions") from the Underwriter and said Transferee to the Trust. In the
absence of Allocation Instructions, the Trust shall have no obligations to a
Transferee.

         4.       Nothing herein contained shall be deemed to require the Trust
to take any action contrary to its Agreement and Declaration of Trust, as it may
be amended or restated from time to time, or By-Laws or any applicable statutory
or regulatory requirement to which it is subject or by which it is bound, or to
relieve or deprive the Trust's Board of Trustees of the responsibility for and
control of the conduct of the affairs of the Trust; it being understood that
actions taken pursuant to Section 1(b) shall not be considered such an action
described above.

         5.       This Class B Plan shall become effective upon approval by (i)
a "majority of the outstanding voting securities" of Class B of the Trust, (ii)
a vote of the Board of Trustees, and (iii) a vote of a majority of the Trustees
who are not "interested persons" of the Trust and who have no direct or indirect
financial interest in the operation of the Class B Plan or in any agreements
related to the Class B Plan (the "Qualified Trustees"), such votes with respect
to (ii) and (iii) above to be cast in person at a meeting called for the purpose
of voting on this Class B Plan.

         6.       All of the terms of this Distribution Plan, as amended and
restated as of September 30, 1998, are intended to apply in respect of all
Pre-Amendment Class B Shares and to the Distribution Fees payable in respect of
any thereof. This Class B Plan will remain in effect indefinitely, provided that
such continuance is "specifically approved at least annually" by a vote of both
a majority of the Trustees of the Trust and a majority of the Qualified
Trustees. If such annual approval is not obtained, this Class B Plan shall
expire on the annual anniversary of the adoption of this Plan following the last
such approval.

         7.       Subject to the limitation set forth in Section 1(b) with
respect to Pre-Amendment Class B shares, this Class B Plan may be amended at any
time by the Board of Trustees with respect to Class B Shares (and the assets
attributable to such Class B Shares) which are not Pre-Amendment Class B Shares
("Post-Amendment Class B Shares"); provided that this Class B Plan may not be
amended to increase materially the limitations on the annual percentage of
average net assets which may be expended hereunder without the approval of
holders of a "majority of the outstanding voting securities" of Class B of the
Trust and may not be materially amended in any case without a vote of a majority
of both the Trustees and the Qualified Trustees. This Class B Plan may be
terminated at any time, subject to Section 1(b), by a vote of a majority of the
Qualified Trustees or by a vote of the holders of a "majority of the outstanding
voting securities" of Class B of the Trust.

         8.       The Trust and the Underwriter shall provide to the Trust's
Board of Trustees, and the Board of Trustees shall review, at least quarterly, a
written report of


                                       -6-


<PAGE>   130


the amounts expended under this Class B Plan and the purposes for which such
expenditures were made.

         9.       While this Class B Plan is in effect, the selection and
nomination of Qualified Trustees shall be committed to the discretion of the
Trustees who are not "interested persons" of the Trust.

         10.      For the purposes of this Class B Plan, the terms "interested
persons," "majority of the outstanding voting securities" and "specifically
approved at least annually" are used as defined in the 1940 Act.

         11.      The Trust shall preserve copies of this Class B Plan, and each
agreement related hereto and each report referred to in Paragraph 7 hereof
(collectively, the "Records"), for a period of not less than six (6) years from
the end of the fiscal year in which such Records were made and, for a period of
two (2) years, each of such Records shall be kept in an easily accessible place.

         12.      This Class B Plan shall be construed in accordance with the
laws of The Commonwealth of Massachusetts and the applicable provisions of the
1940 Act.

         13.      If any provision of this Class B Plan shall be held or made 
invalid by a court decision, statute, rule or otherwise, the remainder of the
Class B Plan shall not be affected thereby.

         14.      Payments under this Class B Plan shall be allocated between
PFD and any successor Underwriter or co-Underwriter (each an Underwriter's
"Allocable Portion) as provided in the Allocation Procedures appended hereto.

                                                                Master Agreement

               FORM OF AMENDED AND RESTATED UNDERWRITING AGREEMENT

         THIS UNDERWRITING AGREEMENT, dated this 31st day of October, 1997 and
amended and restated as of the 30th day of September 1998, by and between
Pioneer Fund, a Delaware business trust ("Trust"), and Pioneer Funds
Distributor, Inc., a Massachusetts corporation (the "Underwriter")

                                   WITNESSETH

         WHEREAS, the Trust is registered as an open-end, diversified,
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"), and has filed a registration statement (the
"Registration Statement") with the Securities and Exchange Commission (the
"Commission") for the purpose of registering shares of beneficial interest for
public offering under the Securities Act of 1933, as amended;

         WHEREAS, the Underwriter engages in the purchase and sale of securities
both as a broker and a dealer and is registered as a broker-dealer with the
Commission and is a member in good standing of the National Association of
Securities Dealers, Inc. (the "NASD");

         WHEREAS, the parties hereto deem it mutually advantageous that the
Underwriter should act as Principal Underwriter, as defined in the 1940 Act, for
the sale to the public of the shares of beneficial interest of the securities
portfolio of each series of the Trust which the Trustees may establish from time
to time (individually, a "Portfolio" and collectively, the "Portfolios"); and

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

         1.       The Trust hereby grants to the Underwriter the right and
option to purchase shares of beneficial interest of each class of each Portfolio
of the Trust(the "Shares") for sale to investors either directly or indirectly
through other broker-dealers. The Underwriter is not required to purchase any
specified number of Shares, but will purchase from the Trust only a sufficient
number of Shares as may be necessary to fill unconditional orders received from
time to time by the Underwriter from investors and dealers.

         2.       The Underwriter shall offer Shares to the public at an
offering price based upon the net asset value of the Shares, to be calculated
for each class of shares as described in the Registration Statement, including
the Prospectus, filed with the Commission and in effect at the time of the
offering, plus sales charges as approved




<PAGE>   132



by the Underwriter and the Trustees of the Trust and as further outlined in
Pioneer's Prospectus. The offering price shall be subject to any provisions set
forth in the Prospectus from time to time with respect thereto, including,
without limitation, rights of accumulation, letters of intent, exchangeability
of shares, reinstatement privileges, net asset value purchases by certain
persons and reinvestments of dividends and capital gain distributions.

         3.       In the case of all Shares sold to investors through other
broker-dealers, a portion of applicable sales charges will be reallowed to such
broker-dealers who are members of the NASD or, in the case of certain sales by
banks or certain sales to foreign nationals, to brokers or dealers exempt from
registration with the Commission. The concession reallowed to broker-dealers
shall be set forth in a written sales agreement and shall be generally the same
for broker-dealers providing comparable levels of sales and service.

         4.       This Agreement shall terminate on any anniversary hereof if
its terms and renewal have not been approved by a majority vote of the Trustees
of the Trust voting in person, including a majority of its Trustees who are not
"interested persons" of the Trust and who have no direct or indirect financial
interest in the operation of the Underwriting Agreement (the "Qualified
Trustees"), at a meeting of Trustees called for the purpose of voting on such
approval. This Agreement may also be terminated at any time, without payment of
any penalty, by the Trust or 60 days' written notice to the Underwriter, or by
the Underwriter upon similar notice to Pioneer. This Agreement may also be
terminated by a party upon five (5) days' written notice to the other party in
the event that the Commission has issued an order or obtained an injunction or
other court order suspending effectiveness of the Registration Statement
covering the Shares of Pioneer. Finally, this Agreement may also be terminated
by the Trust upon five (5) days' written notice to the Underwriter provided
either of the following events has occurred: (i) the NASD has expelled the
Underwriter or suspended its membership in that organization; or (ii) the
qualification, registration, license or right of the Underwriter to sell Shares
in a particular state has been suspended or cancelled in a state in which sales
of the Shares during the most recent 12-month period exceeded 10% of all Shares
held by the Underwriter during such period.

         5.       The compensation for the services of the Underwriter as a
principal underwriter under this Agreement shall be:

         With respect to Class A Shares (i) that part of the sales charge which
         is retained by the Underwriter after allowance of discounts to dealers
         as set forth, if required, in the Registration Statement, including the
         Prospectus, filed with the Commission and in effect at the time of the
         offering, as amended, and (ii) those amounts payable to the Underwriter
         as reimbursement of expenses pursuant to any distribution plan which
         may be in effect.

                                       -2-


<PAGE>   133



         With respect to Class B Shares (i) the Underwriter's Allocable Portion
         (as defined in Section 9) of the Distribution Fee, if any, payable from
         time to time to the Underwriter under the Pioneer's Class B
         Distribution Plan and (ii) the contingent deferred sales charge payable
         with respect to Class B Shares sold through the Underwriter as set
         forth in the Registration Statement, including the Prospectus, filed
         with the Commission and in effect at the time of the sale of such Class
         B Shares.

         With respect to Class C Shares (i) the Distribution Fee, if any,
         payable from time to time to the Underwriter under the Pioneer's Class
         C Distribution Plan and (ii) the contingent deferred sales charge
         payable with respect to Class C Shares sold through the Underwriter as
         set forth in the Registration Statement, including the Prospectus,
         filed with the Commission and in effect at the time of the sale of such
         Class C Shares.

         With respect to Class Y Shares, the Underwriter shall not be entitled
         to any compensation.

         With respect to any future class of shares, the Underwriter shall be
         entitled to such consideration as the Trust and the Underwriter shall
         agree at the time such class of Shares is established.

Notwithstanding anything to the contrary herein, subsequent to the issuance of a
Class B Share the Trust agrees not take any action to waive or change any
contingent deferred sales charge (including, without limitation, by change in
the rules applicable to conversion of Class B Shares into another class) in
respect of such Class B Shares, except (i) as provided in the Trust's Prospectus
or Statement of Additional Information in effect on September 30, 1998, or (ii)
as required by a change in the 1940 Act and the rules and regulations
thereunder, the Conduct Rules of the NASD or any order of any court or
governmental agency enacted, issued or promulgated after September 30, 1998.
Neither the termination of the Underwriter's role as principal underwriter of
the Class B Shares nor the termination of this Agreement nor the termination or
modification of the Class B Distribution Plan shall terminate the Underwriter's
right to the contingent deferred sales charge with respect to Class B Shares
sold through said Underwriter or Class B Shares issued through one or a series
of exchanges of shares of another investment company for which the Underwriter
acts as principal underwriter, in each case with respect to Class B Shares or
their predecessors initially issued prior to such termination or modification
("Pre-Amendment Class B Shares"). Except as provided in the preceding sentences
and notwithstanding any other provisions of the Agreement or the Class B
Distribution Plan, the Underwriter is entitled to its Allocable Portion of the
contingent deferred sales charges payable in respect of the Pre-Amendment Class
B Shares shall be absolute and unconditional and shall not be subject to
dispute, offset, counterclaim or


                                       -3-


<PAGE>   134



any defense whatsoever, at law or equity, including, without limitation, any of
the foregoing based on the insolvency or bankruptcy of such Underwriter.

         6.       Notwithstanding anything to the contrary set forth in the
Distribution Plan or this Agreement, the Trust agrees to comply with respect to
Pre-Amendment Shares with the provision of Sections 1(b), (d), (g) and (h) and
Section 4 and Section 6 of the Trust's Amended and Restated Class B Distribution
Plan as thought such provision were set forth in this Agreement.

         7.       Nothing contained herein shall relieve the Trust of any
obligation under its management contract or any other contract with any
affiliate of the Underwriter.

         8.       Notwithstanding anything to the contrary set forth in the
Class B Distribution Plan or this Agreement the Trust acknowledges that the
Underwriter may assign, sell or pledge (collectively, "Transfer") its rights to
Distribution Fees and contingent deferred sales charges with respect to Class B
Shares. Upon receipt of notice of such Transfer, the Trust shall pay to the
assignee, purchaser or pledgee (collectively with their subsequent transferees,
"Transferees"), as third party beneficiaries, such portion of the Distribution
Fees and contingent deferred sales charges payable to the Underwriter as
provided in written instructions (the "Allocation Instructions") from the
Underwriter to the Trust and shall pay the balance, if any, to the Underwriter.
In the absence of Allocation Instructions, the Trust shall have no obligations
to a Transferee.

         9.       Payments of the Distribution Fee and contingent deferred sales
charges with respect to Class B shares shall be allocated between the
Underwriter (or its Transferee) and such co- or successor principal underwriter
(each an "Allocable Portion"), as provided in the Allocation Procedures attached
hereto.

         10.      The parties to this Agreement acknowledge and agree that all
liabilities arising hereunder, whether direct or indirect, of any nature
whatsoever, including without limitation, liabilities arising in connection with
any agreement of the Trustor its Trustees as set forth herein to indemnify any
party to this Agreement or any other person, if any, shall be satisfied out of
the assets of the Trust and that no Trustee, officer or holder of shares shall
be personally liable for any of the foregoing liabilities. The Trust's Agreement
and Declaration of Trust describes in detail the respective responsibilities and
limitations on liability of the Trustees, officers, and holders of Shares.

         11.      This Agreement shall automatically terminate in the event of
its assignment (as that term is defined in the 1940 Act).

         12.      In the event of any dispute between the parties, this
Agreement shall be construed according to the laws of The Commonwealth of
Massachusetts.
