                                BY AND BETWEEN

                   OPPENHEIMERFUNDS, INC. (THE "AGREEMENT")

     1.   The Agreement may be cancelled by any party upon ten days of written
notice: (1) if the participation agreement for American General Products between
OFI, American General and OVAF is terminated; (2) if neither American General
nor any underwriter under its control actively promotes American General
Products with OVAF as underlying options to new investors; (3) if either party
is subject to a change of control; or (4) if it is not permissible to continue
this Agreement under laws, rules or regulations applicable to OVAF, OFI or
American General.  Either party may also cancel this Agreement upon six months
written notice.

     2.   Payment will be made to American General quarterly during the term
this Agreement is in effect, no later than thirty days after the end of the
quarter starting with the quarter ending December 31, 1999.  Payments shall be
separately computed on the average net assets of OVAF held by American General
Products variable account during the prior quarter, subject to a limit of one-
third of the average management fee paid by that OVAF series to OFI during the
prior quarter, subject to a limit of one-third of the average management fee
paid by that series to OFI during the prior quarter, at the annual rate of:
0.20% of the first $100 million of average net assets, plus 0.25% of average net
assets held by American General Products variable account(s) in excess of $100
million during that prior quarter.  For purposes of determining whether the
breakpoint described in the preceding sentence has been achieved, the net asset
value of OVAF shares held by separate accounts of American General Life
Insurance Company will be aggregated with shares held by American General.

     3.   Except to the extent that American General's, OFI's or OVAF's counsel
may deem it necessary or advisable to disclose in their respective prospectuses
or elsewhere, the terms of this Agreement will be held confidential by each
party.  The party making such disclosure shall provide advance written
notification, including particulars, to the other party that it is making such
disclosure.

     4.   No other fees or expenses will be required of OFI or OVAF for the
sponsorship within American General product line, except as mutually agreed to
by the parties.

     5.   On advance written notice, OFI or a subsidiary may pay all or a
portion of the fees provided for in this Agreement under any service fee or Rule
12b-1 plan hereafter adopted by OVAF, which shall satisfy that portion of OFI's
payment obligation hereunder.

     6.   OFI will be responsible for calculating the fees payable hereunder.

     7.   Each party shall provide each other party or its designated agent
reasonable access


to its records to permit it to audit or review the accuracy of the charges
submitted for payment under this Agreement.

     8.   This Agreement does not modify or replace the November 23, 1998
Agreement by and between American General Annuity Insurance Company and OFI (the
"1998 Agreement"), or any other agreement with American General Life Insurance
Company pertaining to any Oppenheimer fund other than OVAF.  The parties hereto
agree that OVAF assets that qualify for payment under the 1998 Agreement shall
not qualify for payment under this Agreement.
