Re:      Meadowbrook Insurance Group, Inc. ("Borrower") Revolving Credit
         Agreement dated August 3, 1999, as amended (the "Loan Agreement") among
         Comerica Bank and Bank One (the "Lenders"), Comerica Bank, as agent
         (the "Agent") and the Borrower

Dear Mr. Costello:

         Borrower has requested a permanent reduction in the Revolving Credit
Aggregate Commitment from Forty Eight Million Dollars ($48,000,000) to Forty
Seven Million Five Hundred Thousand Dollars ($47,500,000) (the "Reduced
Amount"). Notwithstanding that Section 2.8 of the Loan Agreement requires that
each partial reduction of the Revolving Credit Aggregate Commitment be in an
aggregate amount equal to at least Two Million Dollars ($2,000,000) or a larger
multiple of One Million Dollars ($1,000,000), this letter shall constitute the
Lenders' and Agent's consent to the Reduced Amount; provided, however, (i) Agent
receives executed counterpart signature pages to this letter agreement from the
Lenders and Borrower within five (5) days of the date of this letter agreement,
(ii) Borrower prepays in accordance with the terms of the Loan Agreement, the
amount, if any, by which the sum of the aggregate unpaid principal amount of the
Revolving Credit Advances, plus the Letter of Credit Obligations, exceeds the
Reduced Amount, together with accrued but unpaid interest on the principal
amount of such prepaid Advances to the date of prepayment.

         Capitalized terms not defined to the contrary herein have the meanings
given them in the Loan Agreement.

                                      COMERICA BANK, Agent

         representatives, openly and without limit, the status of any efforts

both, would constitute a default or Event of Default under the Notes or the
Credit Agreement, has occurred and is continuing as of the date hereof.

5.       MISCELLANEOUS

agree that:

                  (a) each of their respective obligations and agreements under
the Loan Documents remain in full force and effect;

         5.3 Agent and Banks expressly reserve the right, at any time subsequent
to the date hereof, to exercise any or all rights and remedies provided under
the Loan Documents, except as modified herein, and to pursue all available
remedies upon the occurrence of an Event of Default. Agent's and Banks' failure
to immediately exercise such rights and remedies shall not be construed as a
waiver or modification of those rights or an offer of forbearance.

         5.4 Future administration of the Liabilities and the financing
arrangements among Agent, Banks, Company and Guarantors shall continue to be
governed by the covenants, terms and conditions of the Loan Documents, which are
incorporated by this reference.

         5.5 Guarantors hereby ratify and affirm that the Guaranty dated as of
August 3, 1999 executed and delivered in connection with the Credit Agreement
remains in full force and effect with respect to the Liabilities and/or any
indebtedness and obligations now or hereafter outstanding or incurred by Company
in connection with this Amendment, the Credit Agreement, the Notes and/or any
other Loan Document.

         5.6 Company, Crest and Meadowbrook, Inc. hereby ratify and affirm that
the Pledge Agreements to which they are party remain in full force and effect
with respect to the Liabilities and/or any indebtedness and obligations now or
hereafter outstanding or incurred by Company in connection with this Amendment,
the Credit Agreement, the Notes and/or any other Loan Document.

         5.7 Company and Guarantors acknowledge and agree the Loan Documents
presently provide for, and they shall reimburse for, any and all costs and
expenses of Agent, including, but not limited to, all inside and outside counsel
fees of Bank whether in relation to drafting, negotiating or enforcement or
defense of the Loan Documents or this Amendment, including any preference or
disgorgement actions and all of Agent's audit fees, incurred by Agent in
connection with Company's liabilities, Agent's administration of Company's
liabilities, any efforts of Bank to collect or satisfy all or any part of
Company's liabilities, and/or all lien searches and financing statement filings.
Company and Guarantors shall immediately reimburse Agent for all of Agent's
costs and expenses upon Agent's incurrence thereof.

         5.8 Company and Agent acknowledge and agree that except as specifically
amended hereby, all of the terms and conditions of the Credit Agreement, the
Notes and the Loan Documents related thereto remain in full force and effect in
accordance with their original terms.

         5.9 Except as specifically waived hereby, nothing set forth in this
Amendment shall constitute, or be interpreted or construed to constitute, a
waiver of any right or remedy of Agent, or of any default or Event of Default
whether now existing or hereafter arising and whether now known or hereafter
discovered by or disclosed to Agent.

         5.10 Agent expressly reserves the right to exercise any or all rights
and remedies provided under the Loan Documents and applicable law except as
modified herein. Agent's failure to immediately exercise such rights and
remedies shall not be construed as a waiver or modification of those rights or
an offer of forbearance.

         5.11 Agent anticipates that discussions addressing the Liabilities may
take place in the future. During the course of such discussions, Agent, Banks,
Company and Guarantors, may

                                     - 8 -

<PAGE>

touch upon and possibly reach a preliminary understanding on one or more
issues prior to concluding negotiations. Notwithstanding this fact and absent an
express written waiver by Agent, Agent and Banks will not be bound by an
agreement on any individual issues unless and until an agreement is reached on
all issues and such agreement is reduced to writing and signed by Company,
Guarantors, Agent and Banks.

         5.12 Company and Guarantors agree to execute any and all additional or
supplemental documentation, and provide such further assistance and assurances
as Agent may require, in Agent's sole and absolute discretion, to give full
effect of the terms, conditions and intentions of this Amendment.

         5.13 Company, in every capacity, including, but not limited to, as
shareholders, partners, officers, directors, investors and/or creditors of
Company, or any one or more of them, hereby waives, discharges and forever
releases Agent and the Banks, Agent's and Banks' respective employees, officers,
directors, attorneys, stockholders and successors and assigns, from and of any
and all claims, causes of action, defenses, counterclaims or offsets Company may
have or may have made which (in any case) could be based on facts or
circumstances known to Company as of the date of this Amendment, against any or
all of Agent and Banks, Agent's and Banks' employees, officers, directors,
attorneys, stockholders and successors and assigns.

         5.14 BORROWER, GUARANTORS AND BANK ACKNOWLEDGE AND AGREE THAT THE RIGHT
TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED. EACH PARTY,
AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF
THEIR CHOICE, KNOWINGLY AND VOLUNTARILY, AND FOR THEIR MUTUAL BENEFIT WAIVES ANY
RIGHT TO TRIAL BY JURY IN THE EVENT OF LITIGATION REGARDING THE PERFORMANCE OR
ENFORCEMENT OF, OR IN ANY WAY RELATED TO, THIS AMENDMENT OR THE LIABILITIES.

         5.15 Agent and Banks reserve the right to terminate its waiver of the
Specified Defaults at any time (I) in the event of any new defaults under the
Loan Documents, (II) in the event of any defaults under this Amendment, (III) in
the event of further deterioration in the financial condition of Borrower or
Guarantor or further deterioration in Bank's collateral position, and/or (IV) in
the event Agent, for any reason, believes that the prospect of payment or
performance is impaired.

         5.16 This Amendment shall be governed and controlled in all respects by
the laws of the State of Michigan, including interpretation, enforceability,
validity and construction.
