                   SUPPLEMENTAL EXECUTIVE RETIREMENT AGREEMENT

         THIS AGREEMENT is made as of the 1st day of February, 1998, by and
between AMERICAN GENERAL CORPORATION, a Texas corporation (the "Company"), and
Robert M. Delvin (the "Executive").

         WHEREAS, the Executive has been employed by the Company in valuable
executive service to the Company; and

         WHEREAS, the Company desires to reward such past service and to
encourage and reward the continued employment of Executive with the Company
until his retirement and to promote his devotion to his duties on behalf of the
Company without uncertainty or concern as to his retirement income security or
that of his spouse;

         NOW, THEREFORE, the Company and the Executive hereby enter into this
Supplemental Executive Retirement Agreement as hereinafter provided:

                                   ARTICLE I.
                                     GENERAL

         Effective Date. This Agreement shall be effective as of February 1,
1998 (the "Effective Date").

         Defined Terms. The definitions of capitalized terms used in this
Agreement (if not provided where a capitalized term initially appears) are
provided in the last Article hereof.

                                   ARTICLE II.
                               RETIREMENT BENEFITS

         Normal Retirement Benefit. If the Executive retires on or after his
Normal Retirement Date, the Retirement Benefit shall be an annual retirement
benefit payable to the Executive for his lifetime, with a ten-year term certain
(the "Normal Retirement Benefit"), in an annual amount equal to (X) minus (Y),
calculated as follows:

         (A) The amount of (X) equals (a) multiplied by (b):



<PAGE>   2

                  (a)    sixty-seven-and-2/10ths percent (67.2%)
                         of such Executive's Final Average Compensation;

                  (b)    the fraction equal to his Years of Service (not in
                         excess of twenty-eight (28) years) divided by
                         twenty-eight (28); and

                  (B) The amount of (Y) equals (e) plus (f) plus (g):

                  (e)    the Social Security Benefit;

                  (f)    the Qualified Plan Benefit; and

                  (g)    the Restoration Plan Benefit.

         Early Retirement Benefit. If the Executive retires on or after his
Early Retirement Date (but before his Normal Retirement Date), the Retirement
Benefit shall be the annual Retirement Benefit computed under Section 2.1,
reduced as follows:

         (A)      If payment of the Retirement Benefit commences
                  after the Executive has attained age sixty
                  (60), the Retirement Benefit shall be reduced
                  by two-and-one-half percent (2.5%) per year for
                  each complete year between such commencement
                  and the Executive's Normal Retirement Date; the
                  reduction per year shall be pro-rated for in
                  complete years;

         (B)      If payment of the Retirement Benefit commences
                  before the Executive attains age sixty (60),
                  the Retirement Benefit shall be further reduced
                  (beyond the reduction imposed by Section 2.2(A)
                  hereof) by five percent (5%) per year for each
                  complete year between such commencement and the
                  Executive's attaining age sixty (60); the reduction 
                  per year shall be pro-rated for incomplete years.

         Termination of Employment Prior to Early Retirement Date and Normal
Retirement Date. If the Executive incurs a termination of employment with the
Company after satisfying the vesting requirement under Section 2.7, but before
attaining either an Early Retirement Date or a Normal Retirement Date, he shall
receive a Retirement Benefit determined under Section 2.1, but, unless such



                                       2
<PAGE>   3

termination is described in Section 2.6 hereof, such benefit shall be calculated
by using his actual Years of Service (including all periods credited as Years of
Service pursuant to this Agreement) and actual compensation at the time of his
termination and the actual Social Security Benefit that he is entitled to
receive at his Normal Retirement Date. Unless such termination is described in
Section 2.6 hereof, payment of such benefit shall commence after, but not more
than sixty (60) days after, his Normal Retirement Date.

         Disability. If the Executive is receiving either short-term or
long-term disability benefits under any Company plan, then, during the period
of payment of such disability benefits, the Executive shall be treated as
employed for all purposes of the Agreement, including, without limitation,
attainment of the age, service and vesting requirements under the Agreement. The
parties hereto agree that such disability benefits will cease and the Executive
will no longer be considered employed by the Company on the date on which the
Executive attains his Normal Retirement Age. Payment of the Executive's
Retirement Benefit shall commence after, but not more than sixty (60) days
after, his Normal Retirement Date.

         Termination by Reason of Death. If the Executive dies (i) while in the
employment of the Company, (ii) after the attainment of age fifty-five (55),
(iii) having been credited with ten (10) Years of Service, and (iv) prior to
the commencement of the payment of the Retirement Benefit hereunder, the
Executive's surviving spouse, if any, shall receive for her lifetime an annual
benefit equal to the two-thirds (2/3) survivor annuity she would have received
had the Executive retired on the day before his death, deeming the Executive,
for purposes of this Section 2.5 only, to have elected a joint and survivor
annuity payable immediately at a reduced amount with a two-thirds (2/3) survivor
annuity. The payment of spouse's benefit shall commence not later than sixty
(60) days after the Executive's death.

         Termination on or after Change in Control; Certain Other Terminations.
Notwithstanding any other provision of this Agreement, upon any termination of
the Executive's employment, whether or not a Change in Control (as defined in
the Executive's employment agreement with the Company dated as of February 1,
1998, 




                                       3
<PAGE>   4
 as it may be amended from time to time (the "Employment Agreement")) has
occurred, which termination is (i) by the Company without Cause, (ii) by the
Executive with Good Reason, or (iii) by the Executive in a Special Termination
(as such terms are defined in the Employment Agreement), the Company shall pay
the Executive within the five (5) business days immediately following such
termination a lump sum amount, in cash, equal to the actuarial equivalent of the
Normal Retirement Benefit which the Executive would have accrued, if the
Executive had accumulated (after his termination of employment) thirty-six (36)
additional months of service and age credit (but in no event shall the Executive
be deemed to have accumulated additional service and age credit after the
Executive's sixty-fifth birthday). For purposes of this Section 2.6, an
"actuarial equivalent" shall be determined using the same assumptions utilized
under the American General Retirement Plan (or any successor plan thereto)
immediately prior to the Executive's termination of employment, or, if more
favorable to the Executive, immediately prior to the Change in Control. The
Retirement Benefit so calculated shall be based on a projected Social Security
Benefit that is determined under the provisions of the Social Security Act as in
effect on the date of such Change in Control, using the estimated "primary
insurance amount" the Executive would be entitled to under such Act at his
Normal Retirement Date, assuming (i) the amount of income he is receiving on the
date such Change in Control becomes effective which would be treated as wages
for purposes of such Act would remain constant through his Normal Retirement
Date, and (ii) an annual cost-of-living adjustment equal to four percent (4%).

         Vesting of Retirement Benefit. The Executive shall have a vested right
to his Retirement Benefit upon the occurrence of any of the following while the
Executive is employed by the Company:

                         (i)               his completion of ten (10) Years
                                           of Service;

                         (ii)              the attainment of his Normal
                                           Retirement Age;

                         (iii)             the termination of the Executive's
                                           employment pursuant to Section 8(c)
                                           of the Employment Agreement; or



                                       4
<PAGE>   5

                         (iv)              the occurrence of a Change in Control
                                           at any time.

         Time and Form of Payment.

                  (A) Time of Payment. Except where specifically otherwise
provided herein, the payment of any Retirement Benefit to which the Executive
has become entitled shall commence after, but no more than sixty (60) days
after, the Executive's date of retirement. The Executive shall give the Company
reasonable advance notice in writing of his intention to retire (which shall be
given at least one month before his intended retirement date).

                  (B) Normal Form of Payment. A life annuity with a ten-year
term certain is the normal form of payment of the Retirement Benefit for the
Executive and any actuarial equivalents to be calculated pursuant to this
Agreement will be based on the normal form of payment. If the Executive dies
after payment of the Retirement Benefit in the normal form has commenced,
payments shall continue for the remainder of the ten-year term certain to the
beneficiary or beneficiaries designated by the Executive by written instruction
delivered to the Administrator during the Executive's lifetime. The Executive
may designate one or more primary and contingent beneficiaries to receive the
remaining payments of the Retirement Benefit, and may designate the proportions
in which such beneficiaries are to receive such payments. The Executive may
change such designations from time to time, and the last written designation
filed with the Administrator prior to the Executive's death shall control. If
the Executive fails to specifically designate a beneficiary, or if no
designated beneficiary survives the Executive, payment shall be made by the
Administrator in the following order of priority:

                         (i)         to the Executive's surviving spouse,
                                     or, if none,

                         (ii)        to the Executive's children, or, if
                                     none,


                                       5
<PAGE>   6

                         (iii)       to the Executive's estate.

                  (C) Election of Alternative Forms of Payment. Subject to
Section 2.6 hereof, the Executive can elect that his Retirement Benefit be paid
in any of the following forms by an irrevocable election in writing which is
delivered to the Company within sixty (60) days after the Effective Date, or,
with the permission of the Committee, by an irrevocable election in writing
which is delivered to the Company at any time before his retirement becomes
effective:

                         (i)         a joint and survivor annuity payable
                                     at a reduced amount for the life of
                                     the Executive with a survivor annuity 
                                     for the life of the Executive's
                                     surviving spouse which shall be one
                                     hundred percent (100%) of the annuity 
                                     payable during the joint lives
                                     of the Executive and the surviving
                                     spouse;

                         (ii)        a joint and survivor annuity payable
                                     at a reduced amount for the life of
                                     the Executive with a survivor annuity 
                                     for the life of the Executive's
                                     surviving spouse which shall be
                                     seventy-five percent (75%) of the
                                     annuity payable during the joint
                                     lives of the Executive and the 
                                     surviving spouse;

                         (iii)       a joint and survivor annuity payable
                                     at a reduced amount for the life of
                                     the Executive with a survivor annuity 
                                     for the life of the Executive's
                                     surviving spouse which shall be
                                     fifty percent (50%) of the annuity
                                     payable during the joint lives of
                                     the Executive and the surviving
                                     spouse; or

                         (iv)        a lump-sum payment of the actuarial present
                                     value of the normal form of payment of the
                                     Retirement Benefit.

<PAGE>   7

In calculating an alternative form of payment for the Retirement Benefit, the
Administrator shall use the same assumptions utilized under the American General
Retirement Plan (or any successor plan thereto) immediately prior to the
Executive's termination of employment, or, if a Change in Control shall have
occurred prior to the Executive's termination of employment, the assumptions so
utilized immediately prior to the Change in Control, if more favorable to the
Executive.

                                  ARTICLE III.
                                 ADMINISTRATION

         General. Except as otherwise specifically provided in the Agreement,
the Administrator shall be responsible for administration of the Agreement.

                  interpret and construe the provisions of the Agreement, to
                  determine eligibility for a Retirement Benefit and the
                  appropriate amount of any Retirement Benefit, to decide any
                  question which may arise regarding the rights of the Executive
                  hereunder and to exercise such powers as the Administrator
                  may deem necessary for the administration of the Agreement.

         (C)      The Administrator shall maintain full and complete records of
                  its decisions. Its records shall contain all relevant data

<PAGE>   9

                  (iv)   an explanation of the claims review procedure
                         under the Agreement.

         Appeals Procedure. In order that a claimant may appeal a denial of a
claim, the claimant or the claimant's duly authorized representative may:

                  (i)    request a review by written application to the
                         Committee, no later than sixty (60) days after receipt
                         by the claimant of written notification of denial of a
                         claim;

                  (ii)   review pertinent documents; and

                  (iii)  submit issues and comments in writing.

         Review. A decision on review of a denied claim shall be made by the
Committee not later than sixty (60) days after receipt of a request for review,
unless special circumstances require an extension of time for processing, in
which case a decision shall be rendered within a reasonable period of time, but
not later than one-hundred-and-twenty (120) days after receipt of a request for
a review. The decision on review shall be in writing and shall include the
specific reason(s) for the decision and the specific reference(s) to the
pertinent provisions of the Agreement on which the decision is based.

         Section 4.6 Arbitration. Any further dispute or controversy arising
under or in connection with this Agreement which is not resolved by agreement
pursuant to Sections 4.1 through 4.5 hereof shall be resolved by binding
arbitration pursuant to the Federal Arbitration Act in accordance with the
Employment Dispute Resolution Rules then in effect with the American Arbitration
Association. The arbitration proceeding shall be conducted in Houston, Texas.
This agreement to arbitrate shall be enforceable in either federal or state
court.

         The enforcement of this agreement to arbitrate and all procedural
aspects of this agreement to arbitrate, including but not limited to, the
construction and interpretation of this agreement to arbitrate, the issues
subject to arbitration (i.e., arbitrability), the scope of the arbitrable
issues, allegations of waiver, delay or 




                                       9
<PAGE>   10

defenses to arbitrability, and the rules governing the conduct of the
arbitration, shall be governed by and construed pursuant to the Federal
Arbitration Act and shall be decided by the arbitrators. In deciding the
substance of any such claims, the arbitrators shall apply the substantive laws
of the State of Texas (excluding Texas choice-of-law principles that might call
for the application of some other state's law); provided, however, it is
expressly agreed that the arbitrators shall have no authority to award treble,
exemplary, or punitive damages under any circumstances regardless of whether
such damages may be available under Texas law, the parties hereby waiving their
right, if any, to recover treble, exemplary, or punitive damages in connection
with any such claims.

         The arbitration may be initiated by any party by providing to the other
parties a written notice of arbitration specifying the claims. Within thirty
(30) days of the notice of initiation of the arbitration procedure, (1) the
Executive shall denominate one arbitrator and (2) the Company shall denominate
one arbitrator. The two arbitrators shall select a third arbitrator failing
agreement on which within sixty (60) days of the original notice, either the
Executive or the Company shall apply to the Senior Active United States District
Judge for the Southern District of Texas, who shall appoint a third arbitrator.
While the third arbitrator shall be neutral, the two party-appointed arbitrators
are not required to be neutral and it shall not be grounds for removal of either
of the two party-appointed arbitrators or for vacating the arbitrators' award
that either of such arbitrators has past or present minimal relationships with
the party that appointed such arbitrator. Evident partiality on the part of an
arbitrator exists only where the circumstances are such that a reasonable person
would have to conclude there in fact existed actual bias and a mere appearance
or impression of bias will not constitute evident partiality or otherwise
disqualify an arbitrator.

         The three arbitrators shall by majority vote resolve all disputes
between the parties. There shall be no transcript of the hearing before the
arbitrators. The arbitrators' decision shall be in writing, but shall be as
brief as possible. The arbitrators shall not assign the reasons for their
decision. The arbitrators shall 



                                       10

         Severability. If any provision of the Agreement shall be held illegal
or invalid for any reason, such illegality or invalidity shall not affect the

enforced as if such illegal or invalid provision had never been included herein.

         Notification of Addresses. The Executive and each beneficiary shall
file with the Administrator, from time to time, in writing, the post office
address of the Executive, the post office address of each beneficiary, and each
change of post office address. Any communication, statement or notice addressed

or any other right, title or interest of any kind in or to any property of the
Company. The Agreement shall constitute merely the unsecured promise of the
Company to make the benefit payments provided for herein. Notwithstanding the
foregoing provisions of this Section 5.10, the Company, in its discretion, may




                                       12

hereunder which are not paid in accordance with the provisions hereof by such
trust.
