         increase or reduction of capital or any certificate issued in
         connection with any reorganization), option or rights, whether in
         addition to, in substitution of, as a conversion of, or in exchange for
         any shares of the Pledged Stock or other Collateral, or otherwise in
         respect thereof, the Pledgor shall accept the same as the agent of the
         Administrative Agent, hold the same in trust for the Administrative
         Agent and deliver the same forthwith to the Administrative Agent in the
         exact form received, duly indorsed by the Pledgor to the Administrative
         Agent, if required, together with an undated stock power covering such

                           (d)      Except as expressly permitted by the Credit
         Agreement, without the prior written consent of the Administrative
         Agent, the Pledgor will not (i) vote to enable, or take any other
         action to permit, any Issuer to issue any stock or other equity

         such further instruments and documents and take such further actions as
         the Administrative Agent may reasonably request for the purposes of
         obtaining or preserving the full benefits of this Pledge Agreement and
         of the rights and powers herein granted. If any amount payable under or
         in connection with any of the Collateral shall be or become evidenced
         by any promissory note, other instrument or chattel paper, such note,
         instrument or chattel paper shall be immediately delivered to the
         Administrative Agent, duly endorsed in a manner satisfactory to the

         Agreement.

                           (f)      The Pledgor agrees to pay, and to save the
         Administrative Agent and the Lenders harmless from, any and all
         liabilities with respect to, or resulting from any delay in paying, any
         and all stamp, excise, sales or other similar taxes which may be
         payable or determined to be payable with respect to any of the
         Collateral or in connection with any of the transactions contemplated
         by this Pledge Agreement.

                           (g)      On or prior to the formation or acquisition
         of any Subsidiary of the Pledgor that is or is expected to be a
         Significant Subsidiary, other than MEEMIC and its Subsidiaries, the
         Pledgor agrees at the request of the Administrative Agent, to execute
         such amendments and supplements to this Pledge Agreement, including
         without limitation the Pledge Agreement Supplement attached hereto, and
         such other documents and instruments and to take any and all actions,
         all as shall be necessary, in the reasonable judgment of the
         Administrative Agent, to pledge the Pledgor's interest therein to the
         Administrative Agent for the ratable benefit of itself and the Lenders.

                  7.       CASH DIVIDENDS AND DISTRIBUTIONS; VOTING RIGHTS.

shareholder, partnership and membership distributions paid in accordance with
the terms of the Credit

                                       4
<PAGE>   5

Agreement in respect of the Collateral and to exercise all voting and corporate,
partnership or membership rights, as applicable, with respect to the Collateral;
provided, that no vote shall be cast or corporate, partnership or membership
right exercised or other action taken which, in the Administrative Agent's
reasonable judgment, would impair the Collateral or which would result in any
violation of any provision of the Credit Agreement, the Notes, any other Loan
Documents or this Pledge Agreement.

continuing and the Administrative Agent shall give notice of its intent to
exercise such rights to the Pledgor, and subject to the receipt of any
applicable approvals from Insurance Regulators, and compliance by Administrative
Agent and Lenders with any applicable filing or other requirements of the
applicable Insurance Regulators, (i) the Administrative Agent shall have the
right to receive any and all cash dividends paid in respect of the Pledged Stock
and partnership and membership distributions in respect of the Partnership
Interests and make application thereof to the Obligation in the order set forth
in SECTION 11.8 of the Credit Agreement and (ii) all shares of the Pledged Stock
shall be registered in the name of the Administrative Agent or its nominee, and
the Administrative Agent or its nominee may thereafter exercise (A) all voting,
corporate and other rights pertaining to such shares of the Pledged Stock at any
meeting of shareholders of the applicable Issuer or otherwise and (B) any and
all rights of conversion, exchange, subscription, and any other rights,
privileges or options pertaining to such shares of the Pledged Stock as if it
were the absolute owner thereof (including, without limitation, the right to
exchange at its discretion any and all of the Pledged Stock upon the merger,
consolidation, reorganization, recapitalization or other fundamental change in
the corporate structure of the applicable Issuer, or upon the exercise by the
Pledgor or the Administrative Agent of any right, privilege or option pertaining
to such shares of the Pledged Stock, and in connection therewith, the right to
deposit and deliver any and all of the Pledged Stock with any committee,
depositary, transfer agent, registrar or other designated agency upon such terms
and conditions as it may determine), all without liability except to account for
property actually received by it, but the Administrative Agent shall have no
duty to the Pledgor to exercise any such right, privilege or option and shall
not be responsible for any failure to do so or delay in so doing.

                           (b)      The rights of the Administrative Agent and
the Lenders hereunder shall not be conditioned or contingent upon the pursuit by
the Administrative Agent or any Lender of any right or remedy against the
Pledgor or against any other Person which may be or become liable in respect of
all or any part of the Obligation or against any collateral security therefor,
guarantee therefor or right of offset with respect thereto. Neither the
Administrative Agent nor any Lender shall be liable for any failure to demand,
collect or realize upon all or any part of the Collateral or for any delay in
doing so, nor shall the Administrative Agent be under any obligation to sell or
otherwise dispose of any Collateral upon the request of the Pledgor or any other
Person or to take any other action whatsoever with regard to the Collateral or
any part thereof.

                           (c)      Pledgor agrees to cooperate with and assist
Administrative Agent and Lenders in connection with any filings to be with, or
approvals required from, any Insurance Regulators or other Governmental
Authorities.

                  9.       REMEDIES. If an Event of Default shall occur and be
continuing, with the consent of the Required Lenders, and subject to the receipt
of any applicable approvals from Insurance Regulators, and compliance by
Administrative Agent and Lenders with any applicable filing or other
requirements of the applicable Insurance Regulators, the Administrative Agent
may, and upon the request of the Required Lenders, the Administrative Agent
shall, exercise on behalf of itself and the Lenders, all rights and remedies
granted in this Pledge Agreement and in any other instrument or agreement
securing, evidencing or relating to the Obligation, and in addition thereto, all
rights and remedies of a secured party under the Code. Without limiting the

                                       5
<PAGE>   6

generality of the foregoing with regard to the scope of the Administrative
Agent's remedies, the Administrative Agent, without demand of performance or
other demand, presentment, protest, advertisement or notice of any kind (except
any notice required by law referred to below) to or upon the Pledgor, any
Issuer, any Partnership or any other Person (all and each of which demands,
defenses, advertisements and notices are hereby waived), may in such
circumstances forthwith collect, receive, appropriate and realize upon the
Collateral, or any part thereof, and/or may forthwith sell, assign, give option
or options to purchase or otherwise dispose of and deliver the Collateral or any
part thereof (or contract to do any of the foregoing), in one or more parcels at
public or private sale or sales, in the over-the-counter market, at any
exchange, broker's board or office of the Administrative Agent or any Lender or
elsewhere upon such terms and conditions as it may deem advisable and at such
prices as it may deem best, for cash or on credit or for future delivery without
assumption of any credit risk. The Administrative Agent or any Lender shall have
the right upon any such public sale or sales, and, to the extent permitted by
law, upon any such private sale or sales, to purchase the whole or any part of
the Collateral so sold, free of any right or equity of redemption in the
Pledgor, which right or equity is hereby waived or released. The Administrative
Agent shall apply any Proceeds from time to time held by it and the net proceeds
of any such collection, recovery, receipt, appropriation, realization or sale,
after deducting all reasonable costs and expenses of every kind incurred in
respect thereof or incidental to the care or safekeeping of any of the
Collateral or in any way relating to the Collateral or the rights of the
Administrative Agent and the Lenders hereunder, including, without limitation,
reasonable attorneys' fees and disbursements of counsel thereto, to the payment
in whole or in part of the Obligation, in the order set forth in SECTION 11.8 of
the Credit Agreement, and only after such application and after the payment by
the Administrative Agent of any other amount required by any provision of law,
including, without limitation, Section 9-504(1)(c) of the Code (or any
successor provision), need the Administrative Agent account for the surplus, if
any, to the Pledgor. To the extent permitted by applicable law, the Pledgor
waives all claims, damages and demands it may acquire against the Administrative
Agent or any Lender arising out of the exercise by them of any rights hereunder.
If any notice of a proposed sale or other disposition of Collateral shall be
required by law, such notice shall be deemed reasonable and proper if given at
least 10 days before such sale or other disposition.

                  10.      REGISTRATION RIGHTS; PRIVATE SALES.

                           (a)      If the Administrative Agent shall determine
to exercise its right to sell any or all of the Collateral pursuant to PARAGRAPH
9 hereof, and if in the opinion of the Administrative Agent it is necessary or
advisable to have such Collateral, or that portion thereof to be sold,
registered under the provisions of the Security Act of 1933, as amended (the
"Securities Act"), the Pledgor will use its best efforts to cause the applicable
Issuer or Partnership to (i) execute and deliver, and use its best efforts to
cause the directors, officers and representatives of the applicable Issuer or
Partnership to execute and deliver, all such instruments and documents, and do
or cause to be done all such other acts as may be, in the opinion of the
Administrative Agent, necessary or advisable to register such Collateral, or
that portion thereof to be sold, under the provisions of the Securities Act,
(ii) to use its best efforts to cause the registration statement relating
thereto to become effective and to remain effective for a period of one year
from the date of the first public offering of such Collateral or that portion
thereof to be sold, and (iii) to make all amendments thereto and/or to the
related prospectus which, in the opinion of the Administrative Agent, are
necessary or advisable, all in conformity with the requirements of the
Securities Act and the rules and regulations of the Securities and Exchange
Commission applicable thereto. The Pledgor agrees to use its best efforts to
cause the applicable Issuer or Partnership to comply with the provisions of the
securities or "Blue Sky" laws of any and all jurisdictions which the
Administrative Agent shall designate and to make available to its security
holders, as soon as practicable, an earnings statement (which need not be
audited) which will satisfy the provisions of Section 11(a) of the Securities
Act. For the purposes of this SECTION 10.(A), "applicable Issuer or Partnership"
shall mean each Issuer or Partnership which is a direct or indirect wholly-owned
Subsidiary of the Pledgor.

                           (b)      The Pledgor recognizes that the
Administrative Agent may be unable to effect a public sale of any or all the
Collateral, by reason of certain prohibitions contained in the Securities Act
and applicable state securities laws or otherwise, and may be compelled to
resort to one or more private sales thereof to a restricted group of purchasers
which will be obliged to agree, among other things, to acquire such securities
for their own account for investment and not with a view to the distribution or
resale thereof. The Pledgor acknowledges and agrees that any such private sale
may result in prices and other terms less favorable than if such sale were a
public sale and, notwithstanding such circumstances, agrees that any such
private sale shall be deemed to have been made in a commercially reasonable
manner. The Administrative Agent shall be under no obligation to delay a sale of
any of the Collateral for the period of time necessary to permit the applicable
Issuer or Partnership to register such securities for public sale under the
Securities Act, or under applicable state securities laws, even if the
applicable Issuer or Partnership would agree to do so.

                           (c)      The Pledgor further agrees to use its best
efforts to do or cause to be done all such other acts as may be necessary to
make such sale or sales of all or any portion of the Collateral pursuant to this
PARAGRAPH 10 valid and binding and in compliance with any and all other
applicable Laws and applicable requirements of the Insurance Regulators. The
Pledgor further agrees that a breach of any of the covenants contained in this
PARAGRAPH 10 will cause irreparable injury to the Administrative Agent and the
Lenders not compensable in damages, that the Administrative Agent and the
Lenders have no adequate remedy at law in respect of such breach and, as a
consequence, that each and every covenant contained in this PARAGRAPH 10 shall
be specifically enforceable against the Pledgor, and the Pledgor hereby waives
and agrees not to assert any defenses against an action for specific performance
of such covenants except for a defense that no Event of Default has occurred
under the Credit Agreement.

                  11.      AMENDMENTS, ETC. WITH RESPECT TO THE OBLIGATION. The
Pledgor shall remain obligated hereunder, and the Collateral shall remain
subject to the Lien granted hereby, notwithstanding that, without any
reservation of rights against the Pledgor, and without notice to or further
assent by the Pledgor, any demand for payment of the Obligation made by the
Administrative Agent or any Lender may be rescinded by the Administrative Agent
or such Lender, and any of the Obligations continued, and the Obligation, or the
liability of the Pledgor or any other Person upon or for any part thereof, or
any collateral security or guarantee therefor or right of offset with respect
thereto, may, from time to time, in whole or in part, be renewed, extended,
amended, modified, accelerated, compromised, waived, surrendered, or released by
the Administrative Agent or any Lender, and the Credit Agreement, the Notes, any
other Loan Documents and any other documents executed and delivered in
connection therewith may be amended, modified, supplemented or terminated, in
whole or in part, as the Lenders (or the Required Lenders, as the case may be)
may deem advisable from time to time, and any guarantee, right of offset or
other collateral security at any time held by the Administrative Agent or any
Lender for the payment of the Obligation may be sold, exchanged, waived,
surrendered or released. Neither the Administrative Agent nor any Lender shall
have any obligation to protect, secure, perfect or insure any other Lien at any
time held by it as security for the Obligation or any property subject thereto.
The Pledgor waives any and all notice of the creation, renewal, extension or
accrual of the Obligation or any part thereof and notice of or proof of reliance
by the Administrative Agent or any Lender upon this Pledge Agreement; the
Obligation, and any part thereof, shall conclusively be deemed to have been
created, contracted or incurred in reliance upon this Pledge Agreement; and all
dealings between the Pledgor, on the one hand, and the Administrative Agent and
the Lenders, on the other, shall likewise be conclusively presumed to have been
had or consummated in reliance upon this Pledge Agreement. The Pledgor waives
diligence, presentment, protest, demand for payment and notice of default or
nonpayment to or upon the Pledgor with respect to the Obligation.

                  12.      REGULATORY APPROVAL. The Pledgor will, at its
expense, promptly execute and deliver, or cause the execution and delivery of,
all applications, certificates, instruments, registration statements, filings
and all other documents and papers the Administrative Agent may reasonably
request or as may be required by law in connection with the obtaining of any
consent, approval, registration, qualification or authorization of any Insurance
Regulator or other Governmental Authority or of any other Person necessary or
appropriate for the effective exercise of any rights under this Pledge
Agreement. Without limiting the generality of the foregoing, if an Event of
Default shall have occurred and be continuing, the Pledgor shall take any action
which the Administrative Agent may reasonably request in order to transfer and
assign to the Administrative Agent, or to such one or more third parties as the
Administrative Agent may designate, or to a combination of the foregoing, each
license and Authorization of any Insurance Regulator or other Governmental
Authority. To enforce the provisions of this PARAGRAPH 12, upon the occurrence
and during the continuance of an Event of Default, the Administrative Agent is
empowered to request the appointment of a receiver from any court of competent
jurisdiction. Such receiver shall be instructed to seek from the Insurance
Regulators and all other necessary Governmental Authorities an involuntary
transfer of control of the Pledged Stock or Partnership Interests and
Authorization from the applicable Insurance Regulators for the purpose of
seeking a bona fide purchaser to whom control of such property will ultimately
be transferred. The Pledgor hereby agrees to authorize such an involuntary
transfer of control upon the request of the receiver so appointed and, if the
Pledgor shall refuse to authorize the transfer, its approval may be required by
the court. Upon the occurrence and during the continuance of an Event of
Default, the Pledgor shall further use its best efforts to assist in obtaining
approval of any applicable Insurance Regulator, if required, for any action or
transactions contemplated by this Pledge Agreement including, without
limitation, the preparation, execution and filing with the applicable Insurance
Regulator of the assignor's or transferor's portion of any filings or
applications for consent to the assignment or transfer of control necessary or
appropriate under the rules and regulations of the applicable Insurance
Regulators for the approval of the transfer or assignment of any portion of the
Collateral, together with any other applicable Authorizations. The Pledgor
acknowledges that the assignment or transfer of such rights is integral to the
Administrative Agent's and the Lenders' realization of the value of the
Collateral, that there is no adequate remedy at law for failure by the Pledgor
to comply with the provisions of this PARAGRAPH 12 and that such failure would
cause irreparable injury not adequately compensable in damages, and therefore
agrees that each and every covenant contained in this PARAGRAPH 12 may be
specifically enforced, and the Pledgor hereby waives and agrees not to assert
any defenses against an action for specific performance of such covenants.

                  13.      LIMITATION ON DUTIES REGARDING COLLATERAL. The
Administrative Agent's sole duty with respect to the custody, safekeeping and
physical preservation of the Collateral in its possession, under Section 9-207
of the Code or otherwise, shall be to deal with it in the same manner as the
Administrative Agent deals with similar securities and property for its own
account. Neither the Administrative Agent, any Lender nor any of their
respective directors, officers, employees or agents shall be liable for failure
to demand, collect or realize upon any of the Collateral or for any delay in
doing so or shall be under any obligation to sell or otherwise dispose of any
Collateral upon the request of the Pledgor or otherwise.

                  14.      POWERS COUPLED WITH AN INTEREST. All authorizations
and agencies herein contained with respect to the Collateral constitute
irrevocable powers coupled with an interest.

                  15.      SEVERABILITY. Any provision of this Pledge Agreement
which is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and

                                       8
<PAGE>   9

any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction.

                  16.      PARAGRAPH HEADINGS. The paragraph headings used in
this Pledge Agreement are for convenience of reference only and are not to
affect the construction hereof or be take into consideration in the
interpretation hereof.

                  17.      NO WAIVER; CUMULATIVE REMEDIES. Neither the
Administrative Agent nor any Lender shall by any act (except by a written
instrument pursuant to PARAGRAPH 18 hereof) be deemed to have waived any right
or remedy hereunder or to have acquiesced in any Default or Potential Default or
in any breach of any of the terms and conditions hereof. No failure to exercise,
nor any delay in exercising, on the part of the Administrative Agent or any
Lender, any right, power or privilege hereunder shall operate as a waiver
thereof. No single or partial exercise of any right, power or privilege
hereunder shall preclude any other or further exercise thereof or the exercise
of any other right, power or privilege. A waiver by the Administrative Agent or
any Lender of any right or remedy hereunder on any one occasion shall not be
construed as a bar to any right or remedy which the Administrative Agent or such
Lender would otherwise have on any future occasion. The rights and remedies
herein provided are cumulative, may be exercised singly or concurrently and are
not exclusive of any other rights or remedies provided by law.

                  18.      WAIVER AND AMENDMENTS; SUCCESSORS AND ASSIGNS;
GOVERNING LAW. None of the terms or provisions of this Pledge Agreement may be
amended, supplemented or otherwise modified except by a written instrument
executed by the Pledgor and the Administrative Agent; provided that any consent
by the Administrative Agent to any waiver, amendment, supplement or modification
hereto shall be subject to approval thereof by the Lenders or Required Lenders,
as applicable, in accordance with SECTION 13.11 of the Credit Agreement. This
Pledge Agreement shall be binding upon the successors and assigns of the Pledgor
and shall inure to the benefit of the Administrative Agent and the Lenders and
their respective successors and assigns. This Pledge Agreement shall be governed
by, and construed and interpreted in accordance with, the laws of the State of
Alabama.

                  19.      NOTICES. All notices and communications hereunder
shall be given to the addresses and otherwise in accordance with SECTION 13.3 of
the Credit Agreement, with notices to Pledgor being sent in care of Borrower.

                  20.      IRREVOCABLE AUTHORIZATION AND INSTRUCTION TO ISSUERS
AND PARTNERSHIPS. The Pledgor hereby authorizes and instructs each Issuer and
Partnership to comply with any instruction received by it from the
Administrative Agent in writing that (a) states that an Event of Default has
occurred and is continuing and (b) is otherwise in accordance with the terms of
this Pledge Agreement, without any other or further instructions from the
Pledgor, and the Pledgor agrees that such Issuer and Partnership shall be fully
protected in so complying.

                  21.      AUTHORITY OF ADMINISTRATIVE AGENT. The Pledgor
acknowledges that the rights and responsibilities of the Administrative Agent
under this Pledge Agreement with respect to any action taken by the
Administrative Agent or the exercise or non-exercise by the Administrative Agent
of any option, voting right, request, judgment or other right or remedy provided
for herein or resulting or arising out of this Pledge Agreement shall, as
between the Administrative Agent and the Lenders, be governed by the Credit
Agreement and by such other agreements with respect thereto as may exist from
time to time among them, but, as between the Administrative Agent and the
Pledgor, the Administrative Agent shall be conclusively presumed to be acting as
agent for itself and the Lenders with full and valid authority so to act or
refrain from acting, and neither the Pledgor nor any Issuer shall be under any
obligation, or entitlement, to make any inquiry respecting such authority.

                                       9
<PAGE>   10

                  22.      CONSENT TO JURISDICTION; INDEMNIFICATION. The Pledgor
hereby irrevocably consents to the personal jurisdiction of the state and
federal courts located in Jefferson County, Alabama, in any action, claim or
other proceeding arising out of or any dispute in connection with this Pledge
Agreement, any rights or obligations hereunder, or the performance of such
rights and obligations. The Pledgor hereby irrevocably consents to the service
of a summons and complaint and other process in any action, claim or proceeding
brought by the Administrative Agent or any Lender in connection with this Pledge
Agreement, any rights or obligations hereunder, or the performance of such
rights and obligations, on behalf of itself or its property, in the manner
provided in SECTION 13.10 of the Credit Agreement, and agrees to indemnify each
Agent, Lead Arranger, Co-Arranger and each Lender as, and to the extent,
provided in SECTION 11.12 of the Credit Agreement. Nothing in this PARAGRAPH 22
shall affect the right of the Administrative Agent or any Lender to serve legal
process in any other manner permitted by Applicable Law or affect the right of
the Administrative Agent or any Lender to bring any action or proceeding against
the Pledgor or its properties in the courts of any other jurisdictions.

                  23.      CONTROL. Notwithstanding anything in this Pledge
Agreement to the contrary, unless and until an Event of Default shall occur and
the Administrative Agent exercises the rights and remedies granted in this
Pledge Agreement in accordance with Paragraph 9 hereof, (a) the execution and
delivery of this Pledge Agreement and the performance of Pledgor's obligations
hereunder (i) do not and will not constitute, create, or have the effect of
constituting or creating, directly or indirectly, actual or practical ownership
of the Issuers or Partnerships by Agents or Lenders, or control, affirmative or
negative, direct or indirect, by Agents or Lenders over the management or any
other aspect of the operation of the Issuers or Partnerships, which ownership or
control remains exclusively and at all times in the Issuers or Partnerships, as
applicable, and (ii) do not and will not constitute the transfer, assignment, or
disposition in any manner, voluntary or involuntary, directly or indirectly, of
any Authorization at any time issued by any Insurance Regulator to any Issuer or
Partnership; and (b) Administrative Agent shall not, without first obtaining
necessary approval of each applicable Insurance Regulator, take any action
pursuant to this Pledge Agreement that would constitute or result in any
assignment of any Authorization or any change of control of any Issuer or
Partnership, if such assignment or change of control would require, under then
existing Law (including the written rules and regulations promulgated by an
applicable Insurance Regulator), the prior approval of such Insurance Regulator.

                  24.      WAIVER OF JURY TRIAL. NOTWITHSTANDING ANY OTHER
PROVISION CONTAINED HEREIN, IN THE EVENT ANY JUDICIAL PROCEEDING IS INSTITUTED
IN CONNECTION WITH THIS PLEDGE AGREEMENT, TO THE EXTENT PERMITTED BY LAW, THE
ADMINISTRATIVE AGENT AND EACH LENDER BY THEIR ACCEPTANCE OF THIS PLEDGE
AGREEMENT OR THE BENEFITS HEREOF AND THE PLEDGOR EACH HEREBY IRREVOCABLY WAIVES
ITS RESPECTIVE RIGHTS TO A JURY TRIAL WITH RESPECT TO ANY ACTION, CLAIM OR OTHER
PROCEEDING ARISING OUT OF OR RELATING TO, OR ANY DISPUTE IN CONNECTION WITH,
THIS PLEDGE AGREEMENT, ANY RIGHTS OR OBLIGATIONS HEREUNDER, OR THE PERFORMANCE
OF SUCH RIGHTS AND OBLIGATIONS.

                           PLEDGE AGREEMENT SUPPLEMENT

                  PLEDGE AGREEMENT SUPPLEMENT, dated as of ____________________,
20___ (the "Supplement"), made by MEDICAL ASSURANCE, INC., a corporation
organized under the laws of Delaware (the "Pledgor"), in favor of SOUTHTRUST
BANK, an Alabama banking corporation, as Administrative Agent (in such capacity,
the "Administrative Agent"), under the Credit Agreement (as defined in the
Pledge Agreement referred to below) for the benefit of itself and the Lenders
(as so defined).

                  1.       Reference is hereby made to that Pledge Agreement,
dated as of May 10, 2001, made by the Pledgor in favor of the Administrative
Agent (as amended, supplemented or otherwise modified as of the date hereof, the
"Pledge Agreement"). This Supplement supplements the Pledge Agreement, forms a
part thereof and is subject to the terms thereof. Terms defined in the Pledged
Agreement are used herein as therein defined.

                  [2.      The Pledgor hereby confirms and reaffirms the
security interest in the Collateral granted to the Administrative Agent for the

                  6.                CERTAIN COVENANTS AND AGREEMENTS. The
                           Pledgor covenants and agrees with the Administrative
                           Agent for the ratable benefit of itself and the
                           Lenders that, from and after the date of this Pledge
                           Agreement until the Obligation is paid in full and
                           the Commitments are terminated:

         (a)               On or before the date of execution of this Pledge
                  Agreement, the Pledgor shall cause each of the partners or
                  members of each of the Partnerships to execute a consent in
                  the form attached hereto evidencing the consent of the
                  partners or members to the pledge of the Partnership Interests
                  pursuant to this Pledge Agreement.

         (b)               The Pledgor agrees that as a partner or member in the
                  Partnerships it will abide by, perform and discharge each and
                  every material obligation, covenant and agreement to be abided
                  by, performed or discharged by Pledgor under the terms of the
                  partnership or membership agreements of the Partnerships, at
                  no cost or expense to the Administrative Agent or the Lenders.

         (c)               If the Pledgor shall, as a result of its ownership of
                  the Pledged Stock or any other Collateral, become entitled to
                  receive or shall receive any stock or other certificate
                  (including, without limitation, any certificate representing a
                  stock dividend or a distribution in connection with any
                  reclassification,

                  connection with any reorganization), option or rights, whether
                  in addition to, in substitution of, as a conversion of, or in
                  exchange for any shares of the Pledged Stock or other
                  Collateral, or otherwise in respect thereof, the Pledgor shall
                  accept the same as the agent of the Administrative Agent, hold
                  the same in trust for the Administrative Agent and deliver the
                  same forthwith to the Administrative Agent in the exact form
                  received, duly indorsed by the Pledgor to the Administrative
                  Agent, if required, together with an undated stock power
                  covering such certificate duly executed in blank by the
                  Pledgor and with, if the Administrative Agent so requests,
                  signature guaranteed, to be held by the Administrative Agent,
                  subject to the terms hereof, as additional collateral security
                  for the Obligation.

         (d)               Except as expressly permitted by the Credit
                  Agreement, without the prior written consent of the
                  Administrative Agent, the Pledgor will not (i) vote to enable,
                  or take any other action to permit, any Issuer to issue any
                  stock or other equity securities of any nature or to issue any
                  other securities convertible into or granting the right to
                  purchase or exchange for any stock or other equity securities
                  of any nature of such Issuer, (ii) except as expressly
                  provided to the contrary herein, consent to any modification,
                  extension or alteration of the terms of any partnership or
                  membership agreement of the Partnerships, (iii) accept a
                  surrender of any partnership or membership agreement of any of
                  the Partnerships or waive any breach of or default under any
                  partnership or membership agreement of any of the Partnerships
                  by any other party thereto, (iv) sell, assign, transfer,
                  exchange, or otherwise dispose of, or grant any option with
                  respect to, the Pledged Stock, or (v) create, incur or permit
                  to exist any Lien or option in favor of, or any claim of any
                  Person with respect to, any of the Collateral, or any interest
                  therein, except for the Lien provided for by this Pledge
                  Agreement. The Pledgor will defend the right, title and
                  interest of the Administrative Agent in and to the Collateral
                  against the claims and demands of all Persons whomsoever.

         (e)               At any time and from time to time, upon the written
                  request of the Administrative Agent, and at the sole expense
                  of the Pledgor, the Pledgor will promptly and duly execute and
                  deliver such further instruments and documents and take such
                  further actions as the Administrative Agent may reasonably
                  request for the purposes of obtaining or preserving the full
                  benefits of this Pledge Agreement and of the rights and powers
                  herein granted. If any amount payable under or in connection
                  with any of the Collateral shall be or become evidenced by any
                  promissory note, other instrument or chattel paper, such note,
                  instrument or chattel paper shall be immediately delivered to
                  the Administrative Agent, duly endorsed in a manner
                  satisfactory to the Administrative Agent, to be held as
                  Collateral pursuant to this Pledge Agreement.

         (f)               The Pledgor agrees to pay, and to save the
                  Administrative Agent and the Lenders harmless from, any and
                  all liabilities with respect to, or resulting from any delay
                  in paying, any and all stamp, excise, sales or other similar
                  taxes which may be payable or determined to be payable with
                  respect to any of the Collateral or in connection with any of
                  the transactions contemplated by this Pledge Agreement.

         (g)               On or prior to the formation or acquisition of any
                  Subsidiary of the Pledgor that is or is expected to be a
                  Significant Subsidiary, other than MEEMIC and its
                  Subsidiaries, the Pledgor agrees at the request of the
                  Administrative Agent, to execute such amendments and
                  supplements to this Pledge Agreement, including without
                  limitation the Pledge Agreement Supplement attached hereto,
                  and such other documents and instruments and to take any and
                  all actions, all as shall be necessary, in the reasonable
                  judgment of the Administrative Agent, to pledge the Pledgor's
                  interest therein to the Administrative Agent for the ratable
                  benefit of itself and the Lenders.

                           RIGHTS. Unless an Event of Default shall have
                           occurred and be continuing and the Administrative
                           Agent shall have given notice to the Pledgor of the
                           Administrative Agent's intent to exercise its rights
                           pursuant to PARAGRAPH 8 below, the Pledgor shall be
                           permitted to receive all cash dividends and
                           shareholder, partnership and membership distributions

                           exercise all voting and corporate, partnership or
                           membership rights, as applicable, with respect to the
                           Collateral; provided, that no vote shall be cast or
                           corporate, partnership or membership right exercised
                           or other action taken which, in the Administrative
                           Agent's reasonable judgment, would impair the
                           Collateral or which would result in any violation of
                           any provision of the Credit Agreement, the Notes, any
                           other Loan Documents or this Pledge Agreement.

                  8.                RIGHTS OF THE ADMINISTRATIVE AGENT.

         (a)               If an Event of Default shall occur and be continuing
                  and the Administrative Agent shall give notice of its intent
                  to exercise such rights to the Pledgor, and subject to the
                  receipt of any applicable approvals from Insurance Regulators,
                  and compliance by Administrative Agent and Lenders with any

                  Insurance Regulators, (i) the Administrative Agent shall have
                  the right to receive any and all cash dividends paid in
                  respect of the Pledged Stock and partnership and membership
                  distributions in respect of the Partnership Interests and make
                  application thereof to the Obligation in the order set forth
                  in SECTION 11.8 of the Credit Agreement and (ii) all shares of
                  the Pledged Stock shall be registered in the name of the
                  Administrative Agent or its nominee, and the Administrative
                  Agent or its nominee may thereafter exercise (A) all voting,
                  corporate and other rights pertaining to such shares of the
                  Pledged Stock at any meeting of shareholders of the applicable
                  Issuer or otherwise and (B) any and all rights of conversion,
                  exchange, subscription, and any other rights, privileges or
                  options pertaining to such shares of the Pledged Stock as if
                  it were the absolute owner thereof (including, without
                  limitation, the right to exchange at its discretion any and
                  all of the Pledged Stock upon the merger, consolidation,
                  reorganization, recapitalization or other fundamental change
                  in the corporate structure of the applicable Issuer, or upon
                  the exercise by the Pledgor or the Administrative Agent of any

                  designated agency upon such terms and conditions as it may
                  determine), all without liability except to account for
                  property actually received by it, but the Administrative Agent
                  shall have no duty to the Pledgor to exercise any such right,
                  privilege or option and shall not be responsible for any
                  failure to do so or delay in so doing.

         (b)               The rights of the Administrative Agent and the
                  Lenders hereunder shall not be conditioned or contingent upon
                  the pursuit by the Administrative Agent or any Lender of any
                  right or remedy against the Pledgor or against any other
                  Person which may be or become liable in respect of all or any
                  part of the Obligation or against any collateral security
                  therefor, guarantee therefor or right of offset with respect
                  thereto. Neither the Administrative Agent nor any Lender shall
                  be liable for any failure to demand, collect or realize upon
                  all or any part of the Collateral or for any delay in doing
                  so, nor shall the Administrative Agent be under any obligation
                  to sell or otherwise dispose of any Collateral upon the
                  request of the Pledgor or any other Person or to take any
                  other action whatsoever with regard to the Collateral or any
                  part thereof.

         (c)               Pledgor agrees to cooperate with and assist
                  Administrative Agent and Lenders in connection with any
                  filings to be with, or approvals required from, any Insurance
                  Regulators or other Governmental Authorities.

                  9.                REMEDIES. If an Event of Default shall occur
                           and be continuing, with the consent of the Required
                           Lenders, and subject to the receipt of any applicable
                           approvals from Insurance Regulators, and compliance
                           by Administrative Agent and Lenders with any
                           applicable filing or other requirements of the
                           applicable Insurance Regulators, the Administrative
                           Agent may, and upon the request of the Required
                           Lenders, the Administrative Agent shall, exercise on
                           behalf of itself and the Lenders, all rights and
                           remedies granted in this Pledge Agreement and in any
                           other instrument or agreement securing, evidencing or
                           relating to the Obligation, and in addition thereto,
                           all rights and remedies of a secured party under the
                           Code. Without limiting the

                           generality of the foregoing with regard to the scope
                           of the Administrative Agent's remedies, the
                           Administrative Agent, without demand of performance
                           or other demand, presentment, protest, advertisement
                           or notice of any kind (except any notice required by
                           law referred to below) to or upon the Pledgor, any
                           Issuer, any Partnership or any other Person (all and
                           each of which demands, defenses, advertisements and
                           notices are hereby waived), may in such circumstances
                           forthwith collect, receive, appropriate and realize
                           upon the Collateral, or any part thereof, and/or may
                           forthwith sell, assign, give option or options to
                           purchase or otherwise dispose of and deliver the
                           Collateral or any part thereof (or contract to do any
                           of the foregoing), in one or more parcels at public
                           or private sale or sales, in the over-the-counter
                           market, at any exchange, broker's board or office of
                           the Administrative Agent or any Lender or elsewhere
                           upon such terms and conditions as it may deem
                           advisable and at such prices as it may deem best, for
                           cash or on credit or for future delivery without
                           assumption of any credit risk. The Administrative
                           Agent or any Lender shall have the right upon any
                           such public sale or sales, and, to the extent
                           permitted by law, upon any such private sale or
                           sales, to purchase the whole or any part of the
                           Collateral so sold, free of any right or equity of
                           redemption in the Pledgor, which right or equity is
                           hereby waived or released. The Administrative Agent
                           shall apply any Proceeds from time to time held by it
                           and the net proceeds of any such collection,
                           recovery, receipt, appropriation, realization or
                           sale, after deducting all reasonable costs and
                           expenses of every kind incurred in respect thereof or
                           incidental to the care or safekeeping of any of the
                           Collateral or in any way relating to the Collateral
                           or the rights of the Administrative Agent and the
                           Lenders hereunder, including, without limitation,
                           reasonable attorneys' fees and disbursements of
                           counsel thereto, to the payment in whole or in part
                           of the Obligation, in the order set forth in SECTION
                           11.8 of the Credit Agreement, and only after such
                           application and after the payment by the
                           Administrative Agent of any other amount required by
                           any provision of law, including, without limitation,
                           Section 9-504(1)(c) of the Code (or any successor
                           provision), need the Administrative Agent account for
                           the surplus, if any, to the Pledgor. To the extent
                           permitted by applicable law, the Pledgor waives all
                           claims, damages and demands it may acquire against
                           the Administrative Agent or any Lender arising out of
                           the exercise by them of any rights hereunder. If any
                           notice of a proposed sale or other disposition of
                           Collateral shall be required by law, such notice
                           shall be deemed reasonable and proper if given at
                           least 10 days before such sale or other disposition.

                  10.               REGISTRATION RIGHTS; PRIVATE SALES.

         (a)               If the Administrative Agent shall determine to
                  exercise its right to sell any or all of the Collateral
                  pursuant to PARAGRAPH 9 hereof, and if in the opinion of the
                  Administrative Agent it is necessary or advisable to have such
                  Collateral, or that portion thereof to be sold, registered
                  under the provisions of the Security Act of 1933, as amended
                  (the "Securities Act"), the Pledgor will use its best efforts
                  to cause the applicable Issuer or Partnership to (i) execute
                  and deliver, and use its best efforts to cause the directors,
                  officers and representatives of the applicable Issuer or
                  Partnership to execute and deliver, all such instruments and
                  documents, and do or cause to be done all such other acts as
                  may be, in the opinion of the Administrative Agent, necessary
                  or advisable to register such Collateral, or that portion
                  thereof to be sold, under the provisions of the Securities
                  Act, (ii) to use its best efforts to cause the registration
                  statement relating thereto to become effective and to remain
                  effective for a period of one year from the date of the first
                  public offering of such Collateral or that portion thereof to
                  be sold, and (iii) to make all amendments thereto and/or to
                  the related prospectus which, in the opinion of the
                  Administrative Agent, are necessary or advisable, all in
                  conformity with the requirements of the Securities Act and the
                  rules and regulations of the Securities and Exchange
                  Commission applicable thereto. The Pledgor agrees to use its
                  best efforts to cause the applicable Issuer or Partnership to
                  comply with the provisions of the securities or "Blue Sky"
                  laws of any and all jurisdictions which the Administrative
                  Agent shall designate and to make available to its security
                  holders, as soon as practicable, an earnings statement (which
                  need not be audited) which will satisfy the provisions of
                  Section 11(a) of the Securities Act. For the purposes of this
                  SECTION 10.(A), "applicable Issuer or Partnership" shall mean
                  each Issuer or Partnership which is a direct or indirect
                  wholly-owned Subsidiary of the Pledgor.

         (b)               The Pledgor recognizes that the Administrative Agent
                  may be unable to effect a public sale of any or all the
                  Collateral, by reason of certain prohibitions contained in the
                  Securities Act and applicable state securities laws or
                  otherwise, and may be compelled to resort to one or more
                  private sales thereof to a restricted group of purchasers
                  which will be obliged to agree, among other things, to acquire
                  such securities for their own account for investment and not
                  with a view to the distribution or resale thereof. The Pledgor
                  acknowledges and agrees that any such private sale may result
                  in prices and other terms less favorable than if such sale
                  were a public sale and, notwithstanding such circumstances,
                  agrees that any such private sale shall be deemed to have been
                  made in a commercially reasonable manner. The Administrative
                  Agent shall be under no obligation to delay a sale of any of
                  the Collateral for the period of time necessary to permit the
                  applicable Issuer or Partnership to register such securities
                  for public sale under the Securities Act, or under applicable
                  state securities laws, even if the applicable Issuer or
                  Partnership would agree to do so.

         (c)               The Pledgor further agrees to use its best efforts to
                  do or cause to be done all such other acts as may be necessary
                  to make such sale or sales of all or any portion of the
                  Collateral pursuant to this PARAGRAPH 10 valid and binding and
                  in compliance with any and all other applicable Laws and
                  applicable requirements of the Insurance Regulators. The
                  Pledgor further agrees that a breach of any of the covenants
                  contained in this PARAGRAPH 10 will cause irreparable injury
                  to the Administrative Agent and the Lenders not compensable in
                  damages, that the Administrative Agent and the Lenders have no
                  adequate remedy at law in respect of such breach and, as a
                  consequence, that each and every covenant contained in this
                  PARAGRAPH 10 shall be specifically enforceable against the
                  Pledgor, and the Pledgor hereby waives and agrees not to
                  assert any defenses against an action for specific performance
                  of such covenants except for a defense that no Event of
                  Default has occurred under the Credit Agreement.

                  11.               AMENDMENTS, ETC. WITH RESPECT TO THE
                           OBLIGATION. The Pledgor shall remain obligated
                           hereunder, and the Collateral shall remain subject to
                           the Lien granted hereby, notwithstanding that,
                           without any reservation of rights against the
                           Pledgor, and without notice to or further assent by
                           the Pledgor, any demand for payment of the Obligation
                           made by the Administrative Agent or any Lender may be
                           rescinded by the Administrative Agent or such Lender,
                           and any of the Obligations continued, and the
                           Obligation, or the liability of the Pledgor or any
                           other Person upon or for any part thereof, or any
                           collateral security or guarantee therefor or right of
                           offset with respect thereto, may, from time to time,
                           in whole or in part, be renewed, extended, amended,
                           modified, accelerated, compromised, waived,
                           surrendered, or released by the Administrative Agent
                           or any Lender, and the Credit Agreement, the Notes,
                           any other Loan Documents and any other documents
                           executed and delivered in connection therewith may be
                           amended, modified, supplemented or terminated, in
                           whole or in part, as the Lenders (or the Required
                           Lenders, as the case may be) may deem advisable from
                           time to time, and any guarantee, right of offset or
                           other collateral security at any time held by the
                           Administrative Agent or any Lender for the payment of
                           the Obligation may be sold, exchanged, waived,
                           surrendered or released. Neither the Administrative
                           Agent nor any Lender shall have any obligation to
                           protect, secure, perfect or insure any other Lien at
                           any time held by it as security for the Obligation or
                           any property subject thereto. The Pledgor waives any
                           and all notice of the creation, renewal, extension or
                           accrual of the Obligation or any part thereof and
                           notice of or proof of reliance by the Administrative
                           Agent or any Lender upon this Pledge Agreement; the
                           Obligation, and any part thereof, shall conclusively
                           be deemed to have been created, contracted or
                           incurred in reliance upon this Pledge Agreement; and
                           all dealings between the Pledgor, on the one hand,
                           and the Administrative Agent and the Lenders, on the
                           other, shall likewise be conclusively presumed to
                           have been had or consummated in reliance upon this
                           Pledge Agreement. The Pledgor waives diligence,
                           presentment, protest, demand for payment and notice
                           of default or nonpayment to or upon the Pledgor with
                           respect to the Obligation.

                  12.               REGULATORY APPROVAL. The Pledgor will, at
                           its expense, promptly execute and deliver, or cause
                           the execution and delivery of, all applications,
                           certificates, instruments, registration statements,
                           filings and all other documents and papers the
                           Administrative Agent may reasonably request or as may
                           be required by law in connection with the obtaining
                           of any consent, approval, registration, qualification
                           or authorization of any Insurance Regulator or other
                           Governmental Authority or of any other Person
                           necessary or appropriate for the effective exercise
                           of any rights under this Pledge Agreement. Without
                           limiting the generality of the foregoing, if an Event
                           of Default shall have occurred and be continuing, the
                           Pledgor shall take any action which the
                           Administrative Agent may reasonably request in order
                           to transfer and assign to the Administrative Agent,
                           or to such one or more third parties as the
                           Administrative Agent may designate, or to a
                           combination of the foregoing, each license and
                           Authorization of any Insurance Regulator or other
                           Governmental Authority. To enforce the provisions of
                           this PARAGRAPH 12, upon the occurrence and during the
                           continuance of an Event of Default, the
                           Administrative Agent is empowered to request the
                           appointment of a receiver from any court of competent
                           jurisdiction. Such receiver shall be instructed to
                           seek from the Insurance Regulators and all other
                           necessary Governmental Authorities an involuntary
                           transfer of control of the Pledged Stock or
                           Partnership Interests and Authorization from the
                           applicable Insurance Regulators for the purpose of
                           seeking a bona fide purchaser to whom control of such
                           property will ultimately be transferred. The Pledgor
                           hereby agrees to authorize such an involuntary
                           transfer of control upon the request of the receiver
                           so appointed and, if the Pledgor shall refuse to
                           authorize the transfer, its approval may be required
                           by the court. Upon the occurrence and during the
                           continuance of an Event of Default, the Pledgor shall
                           further use its best efforts to assist in obtaining
                           approval of any applicable Insurance Regulator, if
                           required, for any action or transactions contemplated
                           by this Pledge Agreement including, without
                           limitation, the preparation, execution and filing
                           with the applicable Insurance Regulator of the
                           assignor's or transferor's portion of any filings or
                           applications for consent to the assignment or
                           transfer of control necessary or appropriate under
                           the rules and regulations of the applicable Insurance
                           Regulators for the approval of the transfer or
                           assignment of any portion of the Collateral, together
                           with any other applicable Authorizations. The Pledgor
                           acknowledges that the assignment or transfer of such
                           rights is integral to the Administrative Agent's and
                           the Lenders' realization of the value of the
                           Collateral, that there is no adequate remedy at law
                           for failure by the Pledgor to comply with the
                           provisions of this PARAGRAPH 12 and that such failure
                           would cause irreparable injury not adequately
                           compensable in damages, and therefore agrees that
                           each and every covenant contained in this PARAGRAPH
                           12 may be specifically enforced, and the Pledgor
                           hereby waives and agrees not to assert any defenses
                           against an action for specific performance of such
                           covenants.

                  13.               LIMITATION ON DUTIES REGARDING COLLATERAL.
                           The Administrative Agent's sole duty with respect to
                           the custody, safekeeping and physical preservation of
                           the Collateral in its possession, under Section 9-207
                           of the Code or otherwise, shall be to deal with it in
                           the same manner as the Administrative Agent deals
                           with similar securities and property for its own
                           account. Neither the Administrative Agent, any Lender
                           nor any of their respective directors, officers,
                           employees or agents shall be liable for failure to
                           demand, collect or realize upon any of the Collateral
                           or for any delay in doing so or shall be under any
                           obligation to sell or otherwise dispose of any
                           Collateral upon the request of the Pledgor or
                           otherwise.

                  14.               POWERS COUPLED WITH AN INTEREST. All
                           authorizations and agencies herein contained with
                           respect to the Collateral constitute irrevocable
                           powers coupled with an interest.

                  15.               SEVERABILITY. Any provision of this Pledge
                           Agreement which is prohibited or unenforceable in any
                           jurisdiction shall, as to such jurisdiction, be
                           ineffective to the extent of such prohibition or
                           unenforceability without invalidating the remaining
                           provisions hereof, and

                                       8
<PAGE>   9

                           any such prohibition or unenforceability in any
                           jurisdiction shall not invalidate or render
                           unenforceable such provision in any other
                           jurisdiction.

                  16.               PARAGRAPH HEADINGS. The paragraph headings
                           used in this Pledge Agreement are for convenience of
                           reference only and are not to affect the construction

                           Administrative Agent nor any Lender shall by any act
                           (except by a written instrument pursuant to PARAGRAPH
                           18 hereof) be deemed to have waived any right or
                           remedy hereunder or to have acquiesced in any Default
                           or Potential Default or in any breach of any of the

                           or privilege hereunder shall operate as a waiver
                           thereof. No single or partial exercise of any right,
                           power or privilege hereunder shall preclude any other
                           or further exercise thereof or the exercise of any
                           other right, power or privilege. A waiver by the

                           remedy hereunder on any one occasion shall not be
                           construed as a bar to any right or remedy which the
                           Administrative Agent or such Lender would otherwise
                           have on any future occasion. The rights and remedies
                           herein provided are cumulative, may be exercised

                           Agreement shall be governed by, and construed and
                           interpreted in accordance with, the laws of the State

                  20.               IRREVOCABLE AUTHORIZATION AND INSTRUCTION TO
                           ISSUERS AND PARTNERSHIPS. The Pledgor hereby
                           authorizes and instructs each Issuer and Partnership
                           to comply with any instruction received by it from
                           the Administrative Agent in writing that (a) states
                           that an Event of Default has occurred and is
                           continuing and (b) is otherwise in accordance with
                           the terms of this Pledge Agreement, without any other
                           or further instructions from the Pledgor, and the
                           Pledgor agrees that such Issuer and Partnership shall
                           be fully protected in so complying.

                  21.               AUTHORITY OF ADMINISTRATIVE AGENT. The
                           Pledgor acknowledges that the rights and
                           responsibilities of the Administrative Agent under
                           this Pledge Agreement with respect to any action
                           taken by the Administrative Agent or the exercise or
                           non-exercise by the Administrative Agent of any
                           option, voting right, request, judgment or other
                           right or remedy provided for herein or resulting or
                           arising out of this Pledge Agreement shall, as
                           between the Administrative Agent and the Lenders, be
                           governed by the Credit Agreement and by such other
                           agreements with respect thereto as may exist from
                           time to time among them, but, as between the
                           Administrative Agent and the Pledgor, the
                           Administrative Agent shall be conclusively presumed
                           to be acting as agent for itself and the Lenders with
                           full and valid authority so to act or refrain from
                           acting, and neither the Pledgor nor any Issuer shall
                           be under any obligation, or entitlement, to make any
                           inquiry respecting such authority.

                           Authorization or any change of control of any Issuer
                           or Partnership, if such assignment or change of
                           control would require, under then existing Law
