Mr. Terry Van Gilder
President and Chief Executive Officer
Reliance Insurance Company
Three Parkway
Philadelphia, PA  19102

Dear Mr. Van Gilder:

The Pennsylvania Insurance Department ("Department") received information that
the rating agency, A.M. Best Co., recently downgraded its rating of the
insurance subsidiaries of Reliance Group Holdings, Inc. from A+ to B++ and then
more recently to B. Reliance Insurance Company and its insurance subsidiaries
(Reliance Insurance Company and its insurance subsidiaries now or hereafter
domiciled in the Commonwealth of Pennsylvania being herein referred to as
"Reliance") are subject to these downgraded ratings. The A.M. Best Co. has
stated that it based the rating downgrades on the first quarter financial report
of Reliance and noted worse-than-expected first quarter underwriting results,
unfavorable operating trends and the termination of the offer from Leucadia
National Corporation. The Department is concerned about the potential impact of
these downgrades and any further ratings' downgrades on Reliance's operating
performance.

The Department has expressed the desire to receive further information
concerning the financial condition of Reliance and Reliance is willing to
cooperate with the Department in such endeavor. Accordingly, the Department and
Reliance Insurance Company hereby enter into this Agreement to set forth a
schedule of reports and other transactions for the Department's review, comment,
and/or approval.

Reliance and the Department agree, so long as this Agreement is in effect, as
follows:

        1.  Reliance shall make the following reports:

           a. Reliance shall file a summary statutory financial information
report covering the consolidated results of operations and financial position of
Reliance Insurance company for each month, no later than the last day of the
month following the month being reported upon, commencing with reports covering
the month of July, 2000.

Each report shall be substantially in the agreed upon form of the report
previously delivered to the Department.

           b. Reliance shall submit by August 31, 2000, a detailed business
plan, setting forth projected sales and other dispositions of subsidiaries and
material businesses or lines of business, and projections of future business
operations. Reliance shall provide updates of material changes in the plan
within three (3) business days after such material changes have been adopted by
Reliance.

           c. Reliance shall file reports, for prior review and comment by the
Department, of all proposed material transactions, as defined in Chapter 27 in
Title 31 of the Pennsylvania Code, with its affiliates and with non-affiliates.

        2. Reliance shall not make any payments to or engage in any transactions
or enter into any agreements directly or indirectly with its parent companies or
any sister company of Reliance Insurance Company, without prior review by the
Department, except payments and transactions under agreements existing on the
date hereof (including existing tax allocation, pooling, management, service and
expense allocation agreements and including other agreements described in
footnote 5 to Reliance Insurance Company's Annual Statement to the Department
for the year ended December 31, 1999) but any amendment or modification of any
existing agreement shall be subject to such prior review if the effect of such
modification or amendment would be to increase payments to Reliance's parent
companies or such sister companies under such agreement by more than 5% of the
annual payments thereunder.

        3. Reliance shall not make any withdrawals of monies from its bank
accounts, disbursements or payments outside the ordinary course of business in
amounts exceeding 5% of its then aggregate cash and investments without prior
review by the Department unless pursuant to existing contracts or pursuant to a
transaction submitted for and after review or approval by the Department.

        4. Reliance shall not make any dividend payments or other distributions
to its shareholders without prior approval by the Department which approval
shall not be unreasonably withheld. Reliance has advised the Department that
Reliance is submitting a notice to the Department for its approval hereunder for
the payment of a non-extraordinary dividend in August, 2000 and currently
intends to submit a notice for payment of a non-extraordinary dividend in
November, 2000.

        5. Reliance shall not incur any debt, obligation or liability for
borrowed money not related directly to the ordinary course of business without
prior review by the Department.

        6. Reliance shall not make any new investment of its funds without prior
approval of the Department unless such investment is (a) in connection with any
existing real estate development project, or (b) in accordance with Reliance's
existing investment guidelines (except for new real estate investment assets or
securities with a National Association of Insurance Commissioners Securities
Valuation designation of 3 through 6), or (c) a fixed income security and has a
National Association of Insurance Commissioners Securities Valuation Office
designation of 1 or 2 or an investment grade rating of a nationally recognized
statistical rating agency relied upon by the National Association of Insurance
Commissioners or (d) an equity security included in the S&P 500 Index or the
Russell 2000 Index if, after giving effect to such investment, the aggregate
value of all equity security investments then owned by Reliance does not exceed
5% of the aggregate value of all investments then owned by Reliance.

        7. Reliance shall not, without prior review by the Department,
reallocate personnel or personnel expenses with its parent or any of its
affiliates if in any 12 consecutive-month period commencing July 1, 2000 the
number of employees reallocated to Reliance shall exceed 50 or the aggregate
amount of personnel expenses reallocated to Reliance shall exceed 12% of total
annual personnel expenses of Reliance as at June 30, 2000.

        8. Reliance shall not dispose of any fixed assets (plant, property or

Department.

        9. Reliance shall not enter into new material reinsurance agreements or
amend in any material respect existing material reinsurance agreements without
prior review by the Department (it being understood that renewals of existing
reinsurance agreements, if the terms remain unchanged in all material respects,
will not constitute entering into new reinsurance agreements), except that
Reliance may amend existing reinsurance contracts the recoverables under which,
in the aggregate, do not exceed 9% of the reinsurance recoverables reported in
the statutory accounts of Reliance as at June 30, 2000. For purposes of this
section 9, a "material reinsurance agreement" shall mean a reinsurance agreement
in respect of which total subject ceded premiums exceeds or is expected to
exceed $50,000,000.

        10. Reliance shall not change or amend Reliance's bylaws without prior
review by the Department.

        11. Reliance shall not merge or consolidate with or be acquired by an
entity or person without prior approval by the Department.

        12. Reliance shall give prior notice to the Department of any
transaction that would alter the corporate ownership structure of Reliance
Insurance Company and its insurance subsidiaries domiciled in the Commonwealth
of Pennsylvania as shown on Schedule Y to Reliance's most recent report to the
Department, other than with respect to a transaction otherwise reviewed or
approved by the Department.

        13. Reliance shall not add any individual who is not currently a senior
officer of Reliance or one of its affiliates to the board of directors of
Reliance without prior review by the Department. Reliance shall not appoint any
individual who is not currently a senior officer of Reliance or one of its
affiliates as a chief executive officer, chief operating officer, chief
underwriting officer, chief financial officer, chief actuarial officer, general
counsel or chief claims office ("Key Officer") of Reliance without prior review
by the Department (it being understood that Reliance may appoint acting Key
Officers pending appointment of individuals as Key Officers on a permanent basis
without such prior review and Reliance will notify the Department of any such
appointment within 5 business days following such an appointment).

        14. Reliance shall advise the Department of the terms of any written
group remuneration, consulting, deferred compensation or bonus plans for
directors, officers and employees of Reliance, and of remuneration, consulting,
deferred compensation and bonus plans for all directors for Key Officers.

        15. Reliance shall not enter into any new agreements or revise existing
agreements for any form of current or future remuneration or other compensation,
including severance agreements, (other than severance agreements documenting
terminations under existing plans, policies and agreements), for services
rendered to Reliance by employees of Reliance, without prior approval of the
Department, except for additional compensation payable by Reliance to its
employees (a) in the six-month period ending December 31, 2000 which in the
aggregate does not exceed 9% of the annual aggregate compensation payable by
Reliance as at July 1, 2000 and (b) thereafter in any calendar year which in the

indebtedness for borrowed money without prior review by the Department.

        17. Reliance shall not accept non-cash capital contributions from
Reliance Group Holdings, Inc. without prior review by the Department.

        18. Reliance agrees that, if the Department engages any outside
independent consultants to assist the Department in its analyses of Reliance's
condition, the consultants' fee shall be paid by Reliance. The Department will
not enter into such fee arrangements without reasonable prior notice to and
review by Reliance.

        19. All information, documents and copies thereof obtained by or
disclosed to the Department pursuant to this agreement will be kept strictly
confidential by the Department and not disclosed to any third party except for
information which is generally available to the public. In the event that the
Department is required to disclose any of such information, the Department will
give Reliance prompt written notice of such request.

        20. Reliance shall provide to the Department any additional reports that
the Department reasonably determines are necessary to ascertain the financial
condition of Reliance.

        21. In case any provision of this Agreement requires that the Department
has the right of prior review or comment prior to a transaction or the taking of
action, Reliance shall give written notice of an information with respect to
such transaction or action at least six (6) business days prior to the
consummation of such transaction or the taking of such action. In case any
provision of this Agreement requires that the Department has the right to
approve a transaction or action, Reliance shall give written notice of and
information with respect to such transaction or action at least ten (10)
business days prior to the consummation of such transaction or the taking of
such action and if the Department shall not have disapproved such transaction or
action prior to the end of such 10 business day period, the transaction or
action shall be deemed approved by the Department. In any event, Reliance may

        22. Reliance shall obtain a resolution of the Board of Directors
authorizing Terry Van Gilder, President and Chief Executive Officer of Reliance
Insurance Company, to execute this Agreement for Reliance. A copy of the
resolution is attached as Exhibit A.

        23. The Department and Reliance will, promptly following the end of each
calendar quarter, review the appropriateness of the continuation of this
agreement in light of the financial condition and prospects of Reliance,
including but not limited to its surplus and risk based capital positions and
its performance under its business plan.

              If at the end of any calendar quarter during the term of this
agreement, commencing with the quarter ended September 30, 2002, the ratio
representing Reliance's net losses unpaid (i.e., the sum of net losses and loss
adjustment expenses) as a percentage of Reliance's combined surplus as regards
policyholders, as shown on the quarterly or annual financial statements filed
with the Department (and supported by a statement of actuarial opinion of an
independent qualified actuary relating to loss and loss adjustment expense
reserves reflected therein), is 200% or less, then the provisions and terms of
this agreement requiring prior review, comment or approval by the Department
shall be suspended until such time as such ratio, as shown on a subsequent
quarterly or annual financial statement filed with the Department, shall be more
than 200% provided that during the period of any such suspension Reliance will
not make any dividend payments or other distributions to its shareholders if,
after giving effect thereto and as a result thereof, such ratio would be more
than 200%.

        24. This Agreement shall remain in full force and effect until

            a. Reliance and the Department shall mutually agree to dissolve this
Agreement; or

            b. the Department commences any proceedings or makes any order under
Article V of the Insurance Department Act of May 17, 1921 or Article XIV of the
Insurance company Law of May 17, 1921; or

            c. declaration by the Department of the dissolution of this
Agreement if (i) Reliance shall have breached this Agreement in any material
respect, (ii) the Department shall have given written notice to Reliance of such
breach and (iii) Reliance shall not have cured such breach within 10 business
days of receipt of such notice. Upon such dissolution, the Department may take
action authorized by law, and Reliance hereby agrees that the Department shall
be entitled to issue a cease and desist order or secure injunctive or other
equitable relief with respect to such material breach as the interests of
Reliance 's policyholders, creditors, shareholders or the public may require and
that Reliance will not oppose the issuance of such cease and desist order or the
granting of such relief for any such material breach, without prejudice to
Reliance to seek relief as appropriate before the Pennsylvania Commonwealth
Court.
