March 22, 1994, as follows:

     1.  The last paragraph on page 1 of each Service Agreement, as most
recently amended by the Addendums to Service Agreement dated March 22, 1994, is
deleted in its entirety and the following is substituted therefor:

     This Service Agreement shall remain in full force and effect for the period
     beginning on the date of this Addendum and ending December 31, 2007.
     Thereafter the Agreement shall automatically renew for consecutive ten (10)
     year periods, unless terminated by written notice by either party to the
     other not less than sixty (60) days prior to the termination of the
     original term hereof of any extension hereof.

     2.   Paragraph 2 of each Addendum to Service Agreement dated March 22,
1994 is hereby amended by adding the following thereto:

     If NGIC terminates this Agreement, or if upon expiration of the then
     current term NGIC does not elect or agree to renew the Agreement on the
     terms of the Agreement then in effect, the payments contemplated herein
     shall continue to be paid by NGIC to AGI for a period of five (5) years
     following termination (the "Run-Off Period"), and calculated as provided in
     the Agreement except that for each year during the Run-Off period the Base
     Fee percent and Bonus Fee percent to be used in determining the Base Fee
     and the Bonus Fee for each year shall be the Scheduled Percentage (as
     hereinafter defined) times a fraction, the numerator of which is the
     Aggregate Premium (as hereinafter defined) for such year and the
     denominator of which is the Aggregate Premium for the year immediately
     preceding such year.  If AGI terminates the Agreement for reason other than
     failure by NGIC to make the payments contemplated herein, payments to AGI
     shall cease


                                      66

     upon termination.  For purposes of this paragraph, the following terms
     shall have the following meanings:

     (a)   The "Scheduled Percentage" means the Base Fee percent and the Bonus
     Fee percent as set forth on the Fee Schedule attached to the March 22, 1994
     Addendum to Service Agreement.

ADDENDUM TO SERVICE AGREEMENTS


     (b)   The "Aggregate Premium" for any year means the aggregate direct
     written premium, less return premium, written under the Good Sam, Good Sam
     Referral, Coast to Coast, Rider, and Golf Card Insurance program agreements
     for such year.

     3.  During the Run-Off period, as long as AGI is continuing to receive the
payment described in paragraph 2 of this Addendum, AGI and its affiliates listed
above (but expressly excluding Camping World, Inc. and its subsidiaries) (the
"Program Affiliates") will not use, or sponsor, endorse or recommend, telephone
solicitation or direct mail solicitation that is (a) directed at Insured Members
(as hereinafter defined) and (b) intended for the purpose of soliciting such
Insured Members to cancel, terminate, or allow to lapse insurance policies
acquired pursuant to the Service Agreement and to replace such policies with new
policies offered by an insurance company other than NGIC or its affiliates
through a program sponsored by AGI or the Program Affiliates.  In making or
participating in any such solicitation that is prohibited by the first sentence
in this paragraph 3, or assisting any third party in making any such
solicitation that is prohibited by the first sentence of this paragraph 3, AGI
shall delete from the membership list(s) of it and the Program Affiliates the
names of all Insured Members prior to any such solicitation.  For the purpose of
this paragraph, "Insured Members" means members of a club or affinity group
operated by AGI who are insured pursuant to the Service Agreement.  A member
shall continue to be an Insured member as long as such member continues to pay
premiums that are included in the Aggregate Premium.  A member shall cease being
an Insured Member upon failure to pay when due any premium for an insurance
policy obtained pursuant to the Service Agreement.  NGIC acknowledges that AGI
and the Program Affiliates regularly solicit programs and products to members of
the clubs, affinity groups operated by AGI and to other customers of AGI and the
Program Affiliates and subscribers and recipients of AGI publications, and
except as expressly set forth in this paragraph 3, such marketing, sponsorship
or solicitation shall not constitute a breach in this paragraph 3, provided
that, in addition to making the above membership list deletions, AGI and the
Program Affiliates shall delete any such advertising of property-casualty
insurance products from publications addressed to Insured Members.  If AGI does
not make such deletions from its solicitation and publication mailing lists the
provisions of paragraph 2 above shall be void.

     4.  Except as amended by this Addendum, all provisions of the Service
Agreements shall remain in full force and effect.
