                         BACK OFFICE SERVICES AGREEMENT

                  Back Office Services Agreement ("Agreement") made and entered
into effective as of the 1st day of November, 1996, by and between Managed Asset
Service Corp., a Delaware corporation (the "Servicer"), and Heinold Asset
Management, Inc., a Delaware Corporation (the "General Partner") on its own
behalf and on behalf of each futures fund listed in Schedule 1 for which the
General Partner acts as general partner (each a "Fund").

                              W I T N E S S E T H:

                  WHEREAS, the Fund's business and purpose is to invest in,
reinvest in, hold and trade commodities and commodity futures, forward and
option contracts, as well as any other items which are presently, or may
hereafter become, the subject of futures, forward or option contract trading by
retaining commodity trading advisors (hereinafter collectively referred to as
"Futures Interests") and other investments; and

                  WHEREAS, the Fund, through the General Partner and pursuant to
the Limited Partnership Agreement of the Fund, is authorized to appoint agents
to provide various administrative services to the Fund subject to the oversight
of the General Partner; and

                  WHEREAS, the Fund has heretofore offered limited partnership
interests ("Units") for sale to investors by means of an offering memorandum
including all exhibits thereto, as the same may be amended or supplemented from
time to time (the "Prospectus"); and

                  WHEREAS, the Servicer's present business includes providing
back office administrative services to futures funds and monitoring the
operations and activities of companies engaged in the trading of Futures
Interests; and

                  WHEREAS, the Fund and the Servicer wish to enter into this
Agreement in order to set forth the terms and conditions upon which the Servicer
will provide certain back office administrative services for the Fund in
connection with the conduct by the Fund of its Futures Interest trading
activities during the term of this Agreement.

                  NOW, THEREFORE, in consideration of the mutual premises and
agreements set forth herein, the parties hereto do hereby agree as follows:

         1.       DUTIES OF THE SERVICER.

                  The General Partner and the Fund hereby appoint the Servicer,
and the Servicer hereby accepts appointment, as the provider of back office
administrative services to the Fund. For the period and on the terms and
conditions set forth in this Agreement, the Servicer will perform on behalf of
the Fund, the services set forth on Appendix A subject to the oversight of the
General Partner.

                  The Fund acknowledges that the Servicer's responsibilities
hereunder depend in large measure upon the Servicer receiving accurate
information with respect to the Fund on a timely basis from the General Partner
and/or the Fund's clearing broker at the instruction of the General Partner. The
Fund agrees that the Servicer shall have no liability for its failure to perform
services contemplated hereunder if it is rendered unable to do so because of the
failure of the General Partner and/or the Fund's clearing broker at the
instruction of the General Partner to provide necessary information on the Fund
on a timely basis. The General Partner and the Partnership further acknowledge
and agree that the Servicer will not independently verify the adequacy or
accuracy of the information provided to the Servicer by the General Partner
and/or third parties and that the Servicer shall have no liability for the
adequacy or accuracy of the Services to the extent that the information provided
by the General Partner and/or third parties is the basis for such Services.

         2.       COMPENSATION.

                  In consideration of and as compensation for its services under
this Agreement, the Fund and/or the General Partner will pay the Servicer a
monthly administrative fee as set forth in Appendix B. The Servicer will submit
an invoice to each Fund and/or the General Partner within ten business days
after month-end and each Fund and/or General Partner shall remit payment to the
Servicer by the following month-end.

         3.       TERM AND TERMINATION.

                  This Agreement shall commence on the date hereof and shall
continue in effect until terminated by either party by 30 days' written notice
to the other.

                  In the event of the termination of this Agreement pursuant to
this Paragraph 3, the rights of the Servicer to receive fees earned through the
date of expiration or termination shall survive this Agreement until satisfied.

                  The termination of this Agreement pursuant to this Paragraph 3
with respect to any Fund shall have no effect on any other Fund.

         4.       STANDARD OF INDEMNITY AND LIABILITY.

                  (a) The Servicer agrees to indemnify and hold harmless each of
the Fund and the General Partner from and against any loss, claim, damage,
liability, cost and expense (including, without limitation, attorneys' and
accountants' fees and disbursements), judgments and amounts paid in settlement
(collectively, "Loss") to which the Fund or the General Partner may become
subject, insofar as any such Loss arises out of, relates to, or is based upon
any claim asserted or enforced against the Fund and/or the General Partner to
the extent that such claim is based upon gross negligence or misconduct on the
part of the Servicer, or any violations by the Servicer of any of its
representations, warranties, covenants or agreements contained in this
Agreement.

<PAGE>   3

                  (b) The Servicer agrees to reimburse the Fund for any legal or
other expenses reasonably incurred by it in investigating or defending or
preparing to defend against any such Loss described in subparagraph 4(a), above.

                  (c) The Fund agrees to indemnify and hold harmless the
Servicer from and against any Loss to which the Servicer may become subject,
insofar as such Loss arises out of, relates to, or is based upon any claim
asserted or enforced against the Servicer with respect to this Agreement or the
activities contemplated hereunder to the extent that such claim is not based
upon gross negligence or misconduct on the part of the Servicer or any
violations by the Fund of any of its representations, warranties, covenants or
agreements contained in this Agreement.

                  (d) The Fund agrees to reimburse the Servicer for any legal or
other expenses reasonably incurred by it in connection with investigating or
defending or preparing to defend against any Loss described in subparagraph
4(c), above.

                  (e) Promptly after receipt by a party to be indemnified under
subparagraph 4(a) or 4(c), above, of any notice of the commencement of any
action or proceeding, such indemnified party shall, if a claim in respect
thereof is to be made against the indemnifying party under such subparagraphs,
notify the indemnifying party in writing of the commencement thereof, but the
omission so to notify the indemnifying party shall not relieve it from any
liability which it may have to any indemnified party otherwise than under such
subparagraphs. The requirement that an indemnifying party be given written
notice of the commencement of any action shall be deemed to be satisfied if such
indemnifying party shall have actual knowledge thereof or shall have been given
written notice of the commencement of any action or proceeding within a
reasonable time after the commencement thereof. If any such action shall be
brought against any indemnified party and the indemnified party notifies the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it wishes, to assume the
defense thereof with counsel satisfactory to such indemnified party, and shall
have the right to negotiate and consent to a settlement thereof, provided that
the indemnified party shall have consented to the settlement. After notice from
the indemnifying party to such indemnified party of its election so to assume
the defense thereof, the indemnifying party shall not be liable to such
indemnified party under such subparagraphs for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that
the indemnified party shall have the right to employ counsel to represent it,
if, in the indemnified party's reasonable judgment, it is advisable for such
party to be represented by separate counsel, in which event the fees and
expenses of such separate counsel shall be borne by the indemnified party. No
indemnifying party shall be liable for any settlement of any such action
effected without its consent, but if any such action or proceeding is settled
with the consent of any indemnifying party or if there be a final judgment for
the plaintiff in any such action or proceeding (of which an indemnifying party
shall have been notified), such indemnifying party shall indemnify and hold
harmless each indemnified party from and against any Loss incurred or suffered
by reason of such settlement or judgment.

<PAGE>   4

                  Any indemnification under subparagraphs (a) or (c), above,
unless ordered by a court, shall be made by the indemnifying party only as
authorized in the specific case and only upon a determination by independent
legal counsel in a written opinion that indemnification of the indemnified party
is proper in the circumstances because it has met the applicable standard of
conduct set forth in subparagraphs (a) or (c) above, as the case may be.

                  (f) As used in these subparagraphs (c) and (d), above, the
term "Servicer" shall include the Servicer and as used in these subparagraphs
(a) and (b), above, the term "Fund" shall include the Fund.

                  (g) The provisions of this Paragraph 4 shall survive the
termination or other expiration of this Agreement.

         5.       REPRESENTATIONS AND WARRANTIES.

         the terms of any indenture, mortgage, deed of trust, loan agreement or

         the Fund is bound or to which any of the property or assets of the Fund
         is subject, nor will any such action or performance result in a
         violation of the provisions of the LPA or any statute or any order,

         qualification and in which the failure to be so qualified would

         and authority under its Certificate of Incorporation and By-Laws to
         conduct its business and to perform its obligations under this
         Agreement.

         to the terms of any indenture, mortgage, deed of trust, loan agreement

         which the Servicer is bound or to which any of the property or assets
         of the Servicer is subject, nor will any such action or performance
         result in a violation of the provisions of the By-Laws or the
         Certificate of Incorporation of the Servicer or any statute or any
         order, rule or regulation of any court or governmental authority or
         body having jurisdiction over the Servicer.

                  (c) All representations, warranties and covenants contained in
this Agreement shall be continuing during the term of this Agreement and shall
survive the termination or expiration of this Agreement with respect to any
matter arising while such Agreement was in effect. Each party hereby agrees that
as of the date of this Agreement it is, and during its term shall be, in
