         Grantor in writing to the contrary, such Grantor shall be entitled to
         exercise or refrain from exercising any and all voting and other
         consensual rights pertaining to the Collateral owned by such Grantor or
         any part thereof for any purpose not inconsistent with the terms of
         this Security Agreement or either of the Credit Agreements; provided,
         however, that each Grantor shall not exercise or refrain from
         exercising any such right if such action would have a material adverse
         effect on the value of the Collateral.

                  (ii) Each Grantor shall be entitled to receive and retain any
         and all dividends and interest paid in respect of the Collateral owned

                  (iii) The Collateral Agent shall execute and deliver (or cause
         to be executed and delivered) to each Grantor all such proxies and
         other instruments as such Grantor may reasonably request for the
         purpose of enabling such Grantor to exercise the voting and other
         rights which it is entitled to exercise pursuant to paragraph (i),
         above, and to receive the dividends and interest which it is authorized
         to receive and retain pursuant to paragraph (ii), above.

         receive the dividends and interest which it would otherwise be
         authorized to receive and retain pursuant to Section 4.5.1(ii) shall
         cease, and all such rights shall thereupon become vested in the
         Collateral Agent who shall thereupon have the sole right to exercise or
         refrain from exercising such voting and other consensual rights and to
         receive and hold as Collateral such dividends and interest.

                  (ii) All dividends and interest and other property which are
         received by any Grantor contrary to the provisions of paragraph (i) of
         this Section 4.5.2 shall be received in trust for the benefit of the
         Collateral Agent, shall be segregated from other funds of such Grantor
         and shall be forthwith paid over to the Collateral Agent as Collateral

exercise any right or remedy granted under this Security Agreement shall impair
such right or remedy or be construed to be a waiver of any Event of Default or
an acquiescence therein, and any single or partial exercise of any such right or
remedy shall not preclude any other or further exercise thereof or the exercise
of any other right or remedy. No waiver, amendment or other variation of the
terms, conditions or provisions of this Security Agreement whatsoever shall be
valid unless in writing signed by the Collateral Agent with the concurrence or
at the direction of the Lenders required under Section 11.01 of either of the
Credit Agreements and each Grantor, and then only to the extent in such writing
specifically set forth. All rights and remedies contained in this Security
Agreement or by law afforded shall be cumulative and all shall be available to

         7.1. Rights of Contribution. To the extent that any payment is made on
the Obligations by or on behalf of any Guarantor or Grantor (each, an "Obligor")
under or pursuant to the Guaranty or this Security Agreement (an "Obligor
Payment") which, taking into account all other Obligor Payments then previously
or concurrently made by any other Obligor, exceeds the amount which otherwise
would have been paid by or attributable to such Obligor if each Obligor had paid
the aggregate Obligations satisfied by such Obligor Payment in the same
proportion as such Obligor's "Allocable Amount" (as defined below) (as
determined immediately prior to such Obligor Payment) bore to the aggregate
Allocable Amounts of each of the Obligors as determined immediately prior to the
making of such Obligor Payment, then, following payment in full in cash of the
Obligations and the termination or expiration of all Commitments, such Obligor
shall be entitled to receive contribution and indemnification payments from, and
be reimbursed by, each other Obligor for the amount of such excess, pro rata
based upon their respective Allocable Amounts in effect immediately prior to
such Obligor Payment.

                                       9
<PAGE>

         7.2. Allocable Amount. As of any date of determination, the "Allocable
Amount" of any Obligor shall be equal to the maximum amount of the claim which
could then be recovered from such Obligor with respect to the Obligations
without rendering such claim voidable or avoidable under Section 548 of Chapter
11 of the Bankruptcy Code or under any applicable state Uniform Fraudulent
Transfer Act, Uniform Fraudulent Conveyance Act or similar statute or common
law.

         7.3. Rights Among Obligors. This Section 7.3 is intended only to define
the relative rights of the Obligors, and nothing set forth in this Section 7.3
is intended to or shall impair the obligations of the Obligors to pay any
amounts as and when the same shall become due and payable in accordance with the
terms of the Guaranty or this Security Agreement.

         7.4. Rights as Assets. The parties hereto acknowledge that the rights
of contribution and indemnification hereunder shall constitute assets of the
Obligors to which such contribution and indemnification is owing.

other Obligors with respect to any payments on the Obligations shall be
exercisable upon the full payment of the Obligations in cash and the termination

                   SUBORDINATION OF INTERCOMPANY INDEBTEDNESS

         8.1. Each Grantor agrees that any and all claims of such Grantor
against any other Loan Party with respect to any "Intercompany Indebtedness" (as
hereinafter defined), any endorser, obligor or any other guarantor of all or any
part of the Obligations, or against any of its properties shall be subordinate
and subject in right of payment to the prior payment, in full and in cash, of
all Obligations and to the obligations of Enterprises under the Enterprises
Credit Agreement. If all or any part of the assets of any Loan Party, or the
proceeds thereof, are subject to any distribution, division or application to
the creditors of such Loan Party, whether partial or complete, voluntary or
involuntary, and whether by reason of liquidation, bankruptcy, arrangement,
receivership, assignment for the benefit of creditors or any other action or
proceeding, or if the business of any such Loan Party is dissolved or if
substantially all of the assets of any such Loan Party are sold, then, and in
any such event (such events being herein referred to as an "Insolvency Event"),
any payment or distribution of any kind or character, either in cash, securities
or other property, which shall be payable or deliverable upon or with respect to
any indebtedness of any Loan Party to any Grantor ("Intercompany Indebtedness")
shall be paid or delivered directly to the Collateral Agent for application to
the obligations of Enterprises under the Enterprises Credit Agreement, whether
matured or unmatured, and, after the Enterprises Credit Agreement is repaid in
full, to the Obligations,

                                       10

whether matured or unmatured, under the Short Term Credit Agreement, and, after
the Short Term Credit Agreement has been repaid in full, to the Obligations,
whether matured or unmatured, under the Long Term Credit Agreement. Should any
payment, distribution, security or instrument or proceeds thereof be received by
any Grantor upon or with respect to the Intercompany Indebtedness after any
Insolvency Event and prior to the satisfaction of all of the Obligations and the
termination or expiration of all Commitments of the Lenders, such Grantor shall
receive and hold the same in trust, as trustee, for the benefit of the Lenders
and shall forthwith deliver the same to the Collateral Agent, for the benefit of
the Lenders, in precisely the form received (except for the endorsement or
assignment of the Obligor where necessary), for application to the obligations
of Enterprises under the Enterprises Credit Agreement, whether matured or
unmatured, and, after the Enterprises Credit Agreement is repaid in full, to the
Obligations, whether matured or unmatured, under the Short Term Credit
Agreement, and, after the Short Term Credit Agreement has been repaid in full,
to the Obligations, whether matured or unmatured, under the Long Term Credit
Agreement, and, until so delivered, the same shall be held in trust by such
Grantor as the property of the Lenders.

                                   ARTICLE IX

                               GENERAL PROVISIONS

         9.1. Secured Party Performance of Grantor's Obligations. Without having
any obligation to do so, the Collateral Agent may perform or pay any obligation
which any Grantor has agreed to perform or pay in this Security Agreement and
such Grantor shall reimburse the Collateral Agent for any reasonable amounts
paid by the Collateral Agent pursuant to this Section 9.1. Each Grantor's
obligation to reimburse the Collateral Agent pursuant to the preceding sentence
shall be an Obligation payable on demand.

         9.2. Authorization for Secured Party to Take Certain Action. Each
Grantor irrevocably authorizes the Collateral Agent at any time and from time to
time in the sole discretion of the Collateral Agent and appoints the Collateral
Agent as its attorney in fact (i) to contact and enter into one or more
agreements with the issuers of uncertificated securities which are Collateral
owned by such Grantor and which are Securities or with financial intermediaries
holding other Investment Property as may be necessary or advisable solely to
give the Collateral Agent Control over such Securities or other Investment
Property, (ii) following the occurrence and during the continuance of an Event
of Default, to enforce payment of the Instruments and Accounts which are
Collateral in the name of the Collateral Agent or such Grantor, (iii) following
the occurrence and during the continuance of an Event of Default, to apply the
proceeds of any Collateral received by the Collateral Agent to the Obligations
and (iv) to discharge past due taxes, assessments, charges, fees or Liens on the
Collateral (except for such Liens as are specifically permitted hereunder or
under any other Loan Document), and each Grantor agrees to reimburse the
Collateral Agent on demand for any reasonable payment made or any reasonable
expense incurred by the Collateral Agent in connection therewith, provided that
this authorization shall not relieve any Grantor of any of its obligations under
this Security Agreement or under the Credit Agreements.

shall reimburse the Collateral Agent for any and all reasonable out-of-pocket
expenses and internal charges (including reasonable attorneys', auditors' and
accountants' fees and reasonable time charges of attorneys, paralegals, auditors
and accountants who may be employees of the Collateral Agent) paid or incurred
by the Collateral Agent in connection with the preparation, execution, delivery,
administration, collection and enforcement of this Security Agreement and in the
audit, analysis, administration, collection, preservation or sale of the
Collateral (including the expenses and charges associated with any periodic or
special audit of the Collateral). Any and all costs and expenses incurred by the

         9.7. CHOICE OF LAW. SUBMISSION TO JURISDICTION. THIS SECURITY AGREEMENT
SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF

<PAGE>

AGREES THAT THE COLLATERAL AGENT SHALL HAVE THE RIGHT TO PROCEED AGAINST SUCH
GRANTOR OR ITS PROPERTY IN A COURT IN ANY LOCATION TO ENABLE THE LENDERS TO
REALIZE ON THE COLLATERAL OR ANY OTHER SECURITY FOR THE OBLIGATIONS OR TO
ENFORCE A JUDGMENT OR OTHER COURT ORDER ENTERED IN FAVOR OF THE COLLATERAL AGENT

COUNTERCLAIMS IN ANY PROCEEDING BROUGHT BY THE COLLATERAL AGENT TO REALIZE ON
THE COLLATERAL OR ANY OTHER SECURITY FOR THE OBLIGATIONS, OR TO ENFORCE A
JUDGMENT OR OTHER COURT ORDER IN FAVOR OF THE COLLATERAL AGENT. EACH GRANTOR

         9.8. Indemnity. Each Grantor hereby agrees, jointly with the other
Grantors and severally, to indemnify the Collateral Agent and its successors,
assigns, agents and employees (each, an "indemnified party"), from and against
any and all liabilities, damages, penalties, suits, costs, and expenses of any
kind and nature (including, without limitation, all expenses of litigation or
preparation therefor whether or not the Collateral Agent is a party thereto)
imposed on, incurred by or asserted against the Collateral Agent, or its
successors, assigns, agents and employees, in any way relating to or arising out
of this Security Agreement, or the ownership, delivery, possession, or other
disposition of any Collateral except to the extent that such liabilities,

other Person, and such other Person shall thereupon become vested with all the
benefits in respect thereof granted to such Lender herein or otherwise, subject,

                  4.1.2 Records and Reports. Each Grantor will maintain complete
and accurate books and records with respect to the Collateral owned by such
Grantor, and furnish to the Collateral Agent, with sufficient copies for each of
the Lenders, such reports relating to the Collateral as the Collateral Agent
shall from time to time reasonably request.

                  4.1.3 Financing Statements and Other Actions; Defense of
Title. Each Grantor hereby authorizes the Collateral Agent to file, and if
requested will execute and deliver to the Collateral Agent, all financing
statements describing the Collateral owned by such Grantor and other documents
and take such other actions as may from time to time be reasonably requested by
the Collateral Agent in order to maintain a first perfected security interest in
and, if applicable, Control of, the Collateral owned by such Grantor. Each
Grantor will take any and all actions necessary to defend title to the
Collateral owned by such Grantor against all persons and to defend the security
interest of the Collateral Agent in such Collateral and the priority thereof
against any Lien not expressly permitted hereunder.

                  4.1.4 Change in Corporate Existence, Type or Jurisdiction of
Organization, Location, Name. Each Grantor will preserve its existence, not
change its state of organization, and not change its mailing address, unless, in
each such case, such Grantor shall have given the Collateral Agent not less than
10 days' prior written notice of such event or occurrence and the Collateral
Agent shall have either (x) determined that such event or occurrence will not
adversely affect the validity, perfection or priority of the Collateral Agent's
security interest in the Collateral owned by such Grantor, or (y) taken such
steps (with the cooperation of such Grantor to the extent necessary or
advisable) as are necessary or advisable to properly maintain the validity,
perfection and priority of the Collateral Agent's security interest in the
Collateral owned by such Grantor.

Collateral Agent immediately upon execution of this Security Agreement the
originals of all Securities constituting Collateral owned by such Grantor (if
any then exist), (ii) deliver to the Collateral Agent within thirty days after
execution of this Security Agreement the originals of all Instruments
constituting Collateral owned by such Grantor (if any then exist) and (iii) hold
in trust for the Collateral Agent upon receipt and immediately thereafter

constituting Collateral owned by such Grantor.

         4.3. Uncertificated Securities and Certain Other Investment Property.

appropriate issuers (and, if held with a securities intermediary, such
securities intermediary) of uncertificated securities or other types of
Investment Property not represented by certificates which are Collateral owned
by such Grantor to mark their books and records with the numbers and face
amounts of all such uncertificated securities or other types of Investment
Property not represented by certificates and all rollovers and replacements
therefor to reflect the Lien of the Collateral Agent granted pursuant to this
Security Agreement. Each Grantor will use all commercially reasonable efforts,
with respect to Investment Property constituting Collateral owned by such
Grantor held with a financial intermediary, to cause such financial intermediary
to enter into a control agreement with the Collateral Agent in form and
substance reasonably satisfactory to the Collateral Agent.

         4.4. Stock and Other Ownership Interests. Each Grantor will permit any
registerable Collateral owned by such Grantor to be registered in the name of

                  4.5.1 Rights Prior to Default. So long as no Event of Default,
and no Default under Section 9.01(f) of the Credit Agreement, shall have
occurred and be continuing:

                  (i) Until the Collateral Agent shall have notified each
         Grantor in writing to the contrary, such Grantor shall be entitled to
         exercise or refrain from exercising any and all voting and other
         consensual rights pertaining to the Collateral owned by such Grantor or
         any part thereof for any purpose not inconsistent with the terms of
         this Security Agreement or the Credit Agreement; provided, however,
         that each Grantor shall not exercise or refrain from exercising any
         such right if such action would have a material adverse effect on the
         value of the Collateral.

                  (ii) Each Grantor shall be entitled to receive and retain any
         and all dividends and interest paid in respect of the Collateral owned
         by such Grantor, provided, however, that any and all (a) dividends and
         interest paid or payable other than in cash in respect of, and
         securities, instruments and other property received, receivable or
         otherwise distributed in respect of, or in exchange for, any such
         Collateral, and (b) dividends, interest and other distributions paid or
         payable in cash in respect of any such Collateral in connection with a
         partial or total liquidation or dissolution or in connection with a
         reduction of capital, capital surplus or paid-in-surplus, shall be, and
         shall be forthwith delivered to the Collateral Agent to hold as,
         Collateral and shall, if received by such Grantor, be received in trust
         for the benefit of the Collateral Agent, be segregated from the other
         property or funds of such Grantor, and be forthwith delivered to the
         Collateral Agent as Collateral in the same form as so received (with
         any necessary indorsement or assignment).

                  (iii) The Collateral Agent shall execute and deliver (or cause
         to be executed and delivered) to each Grantor all such proxies and
         other instruments as such Grantor may reasonably request for the
         purpose of enabling such Grantor to exercise the voting and other
         rights which it is entitled to exercise pursuant to paragraph (i),
         above, and to receive the dividends and interest which it is authorized
         to receive and retain pursuant to paragraph (ii), above.

                  4.5.2 Rights During Default. Upon the occurrence and during
the continuance of a Default under Section 9.01(f) of the Credit Agreement or an
Event of Default:

                  (i) Upon written notice to such Grantor by the Collateral
         Agent, all rights of such Grantor to exercise or refrain from
         exercising the voting and other consensual rights which it would
         otherwise be entitled to exercise pursuant to Section 4.5.1(i) and to
         receive the dividends and interest which it would otherwise be
         authorized to receive and retain pursuant to Section 4.5.1(ii) shall
         cease, and all such rights shall thereupon become vested in the
         Collateral Agent who shall thereupon have the sole right to exercise or
         refrain from exercising such voting and other consensual rights and to
         receive and hold as Collateral such dividends and interest.

                  (ii) All dividends and interest and other property which are
         received by any Grantor contrary to the provisions of paragraph (i) of
         this Section 4.5.2 shall

                                       7
<PAGE>

         be received in trust for the benefit of the Collateral Agent, shall be
         segregated from other funds of such Grantor and shall be forthwith paid
         over to the Collateral Agent as Collateral in the same form as so
         received (with any necessary indorsement).

                                   ARTICLE V

                                    DEFAULT

         5.1. Default. The occurrence of any "Event of Default" under, and as
defined in, the Credit Agreement shall constitute an Event of Default hereunder.

         5.2. Acceleration and Remedies. Upon the acceleration of the
Obligations under the Credit Agreement pursuant to Section 9.02 thereof, the
Collateral Agent may, with the concurrence or at the direction of the Required
Secured Parties, exercise any or all of the following rights and remedies:

                  5.2.1 Those rights and remedies provided in this Security
Agreement, the Credit Agreement, or any other Loan Document, provided that this
Section 5.2.1 shall not be understood to limit any rights or remedies available
to the Collateral Agent and the Lenders prior to an Event of Default.

                  5.2.2 Those rights and remedies available to a secured party
under the New York UCC (whether or not the New York UCC applies to the affected
Collateral) or under any other applicable law (including, without limitation,
any law governing the exercise of a bank's right of setoff or bankers' lien)
when a debtor is in default under a security agreement.

                  5.2.3 Without notice except as specifically provided herein,
sell, lease, assign, grant an option or options to purchase or otherwise dispose
of the Collateral or any part thereof in one or more parcels at public or
private sale, for cash, on credit or for future delivery, and upon such other
terms as the Collateral Agent may deem commercially reasonable.

The Collateral Agent may comply with any applicable state or federal law
requirements in connection with a disposition of the Collateral and compliance
will not be considered to adversely affect the commercial reasonableness of any
sale of the Collateral.

                                   ARTICLE VI

                        WAIVERS, AMENDMENTS AND REMEDIES

         6.1. No delay or omission of the Collateral Agent or any Lender to
exercise any right or remedy granted under this Security Agreement shall impair
such right or remedy or be construed to be a waiver of any Event of Default or
an acquiescence therein, and any single or partial exercise of any such right or
remedy shall not preclude any other or further exercise thereof or the exercise
of any other right or remedy. No waiver, amendment or other variation of the
terms, conditions or provisions of this

                                       8
<PAGE>

Security Agreement whatsoever shall be valid unless in writing signed by the
Collateral Agent with the concurrence or at the direction of the Lenders
required under Section 11.01 of the Credit Agreement and each Grantor, and then
only to the extent in such writing specifically set forth. All rights and
remedies contained in this Security Agreement or by law afforded shall be
cumulative and all shall be available to the Collateral Agent and the Lenders
until the Obligations have been paid in full.

                                  ARTICLE VII

               RIGHTS OF CONTRIBUTION WITH RESPECT TO OBLIGATIONS

         7.1. Rights of Contribution. To the extent that any payment is made on
the Obligations by or on behalf of any Guarantor or Grantor (each, an "Obligor")
under or pursuant to the Guaranty or this Security Agreement (an "Obligor
Payment") which, taking into account all other Obligor Payments then previously
or concurrently made by any other Obligor, exceeds the amount which otherwise
would have been paid by or attributable to such Obligor if each Obligor had paid
the aggregate Obligations satisfied by such Obligor Payment in the same
proportion as such Obligor's "Allocable Amount" (as defined below) (as
determined immediately prior to such Obligor Payment) bore to the aggregate
Allocable Amounts of each of the Obligors as determined immediately prior to the
making of such Obligor Payment, then, following payment in full in cash of the
Obligations and the termination or expiration of all Commitments, such Obligor
shall be entitled to receive contribution and indemnification payments from, and
be reimbursed by, each other Obligor for the amount of such excess, pro rata
based upon their respective Allocable Amounts in effect immediately prior to
such Obligor Payment.

         7.2. Allocable Amount. As of any date of determination, the "Allocable
Amount" of any Obligor shall be equal to the maximum amount of the claim which
could then be recovered from such Obligor with respect to the Obligations
without rendering such claim voidable or avoidable under Section 548 of Chapter
11 of the Bankruptcy Code or under any applicable state Uniform Fraudulent
Transfer Act, Uniform Fraudulent Conveyance Act or similar statute or common
law.

         7.3. Rights Among Obligors. This Section 7.3 is intended only to define
the relative rights of the Obligors, and nothing set forth in this Section 7.3
is intended to or shall impair the obligations of the Obligors to pay any
amounts as and when the same shall become due and payable in accordance with the
terms of the Guaranty or this Security Agreement.

         7.4. Rights as Assets. The parties hereto acknowledge that the rights
of contribution and indemnification hereunder shall constitute assets of the
Obligors to which such contribution and indemnification is owing.

         7.5. Rights Deferred. The rights of the indemnifying Obligors against
other Obligors with respect to any payments on the Obligations shall be
exercisable upon the

                                       9
<PAGE>

full payment of the Obligations in cash and the termination or expiry of the
Commitments.

                                  ARTICLE VIII

                   SUBORDINATION OF INTERCOMPANY INDEBTEDNESS

         8.1. Each Grantor agrees that any and all claims of such Grantor
against any other Loan Party with respect to any "Intercompany Indebtedness" (as
hereinafter defined), any endorser, obligor or any other guarantor of all or any
part of the Obligations, or against any of its properties shall be subordinate
and subject in right of payment to the prior payment, in full and in cash, of
all Obligations. If all or any part of the assets of any Loan Party, or the
proceeds thereof, are subject to any distribution, division or application to
the creditors of such Loan Party, whether partial or complete, voluntary or
involuntary, and whether by reason of liquidation, bankruptcy, arrangement,
receivership, assignment for the benefit of creditors or any other action or
proceeding, or if the business of any such Loan Party is dissolved or if
substantially all of the assets of any such Loan Party are sold, then, and in
any such event (such events being herein referred to as an "Insolvency Event"),
any payment or distribution of any kind or character, either in cash, securities
or other property, which shall be payable or deliverable upon or with respect to
any indebtedness of any Loan Party to any Grantor ("Intercompany Indebtedness")
shall be paid or delivered directly to the Collateral Agent for application to
the Obligations, whether matured or unmatured. Should any payment, distribution,
security or instrument or proceeds thereof be received by any Grantor upon or
with respect to the Intercompany Indebtedness after any Insolvency Event and
prior to the satisfaction of all of the Obligations and the termination or
expiration of all Commitments of the Lenders, such Grantor shall receive and
hold the same in trust, as trustee, for the benefit of the Lenders and shall
forthwith deliver the same to the Collateral Agent, for the benefit of the
Lenders, in precisely the form received (except for the endorsement or
assignment of the Obligor where necessary), for application to the Obligations,
whether matured or unmatured, and, until so delivered, the same shall be held in
trust by such Grantor as the property of the Lenders.

                                   ARTICLE IX

                               GENERAL PROVISIONS

         9.1. Secured Party Performance of Grantor's Obligations. Without having
any obligation to do so, the Collateral Agent may perform or pay any obligation
which any Grantor has agreed to perform or pay in this Security Agreement and
such Grantor shall reimburse the Collateral Agent for any reasonable amounts
paid by the Collateral Agent pursuant to this Section 9.1. Each Grantor's
obligation to reimburse the Collateral Agent pursuant to the preceding sentence
shall be an Obligation payable on demand.

                                       10
<PAGE>

         9.2. Authorization for Secured Party to Take Certain Action. Each
Grantor irrevocably authorizes the Collateral Agent at any time and from time to
time in the sole discretion of the Collateral Agent and appoints the Collateral
Agent as its attorney in fact (i) to contact and enter into one or more
agreements with the issuers of uncertificated securities which are Collateral
owned by such Grantor and which are Securities or with financial intermediaries
holding other Investment Property as may be necessary or advisable solely to
give the Collateral Agent Control over such Securities or other Investment
Property, (ii) following the occurrence and during the continuance of an Event
of Default, to enforce payment of the Instruments and Accounts which are
Collateral in the name of the Collateral Agent or such Grantor, (iii) following
the occurrence and during the continuance of an Event of Default, to apply the
proceeds of any Collateral received by the Collateral Agent to the Obligations
and (iv) to discharge past due taxes, assessments, charges, fees or Liens on the
Collateral (except for such Liens as are specifically permitted hereunder or
under any other Loan Document), and each Grantor agrees to reimburse the
Collateral Agent on demand for any reasonable payment made or any reasonable
expense incurred by the Collateral Agent in connection therewith, provided that
this authorization shall not relieve any Grantor of any of its obligations under
this Security Agreement or under the Credit Agreement.

         9.3. Benefit of Agreement. The terms and provisions of this Security
Agreement shall be binding upon and inure to the benefit of the Grantors, the
Collateral Agent and the Lenders and their respective successors and assigns
(including all persons who become bound as a debtor to this Security Agreement),
except that the Grantors shall not have the right to assign their rights or
delegate their obligations under this Security Agreement or any interest herein,
without the prior written consent of the Collateral Agent.

         9.4. Survival of Representations. All representations and warranties of
the Grantors contained in this Security Agreement shall survive the execution
and delivery of this Security Agreement.

         9.5. Taxes and Expenses. Any stamp, documentary or (to the extent
provided in the Credit Agreement) withholding taxes payable or ruled payable by
Federal or State authority in respect of this Security Agreement shall be paid
by the Grantors, together with interest and penalties, if any. The Grantors
shall reimburse the Collateral Agent for any and all reasonable out-of-pocket
expenses and internal charges (including reasonable attorneys', auditors' and
accountants' fees and reasonable time charges of attorneys, paralegals, auditors
and accountants who may be employees of the Collateral Agent) paid or incurred
by the Collateral Agent in connection with the preparation, execution, delivery,
administration, collection and enforcement of this Security Agreement and in the
audit, analysis, administration, collection, preservation or sale of the
Collateral (including the expenses and charges associated with any periodic or
special audit of the Collateral). Any and all costs and expenses incurred by the
Grantors in the performance of actions required pursuant to the terms hereof
shall be borne solely by the Grantors.

                                       11

         9.6. Headings. The title of and section headings in this Security
Agreement are for convenience of reference only, and shall not govern the
interpretation of any of the terms and provisions of this Security Agreement.

         9.7. CHOICE OF LAW. SUBMISSION TO JURISDICTION. THIS SECURITY AGREEMENT
SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
NEW YORK (INCLUDING SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAWS OF THE STATE
OF NEW YORK, BUT OTHERWISE WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES). EACH
OF THE GRANTORS AND THE COLLATERAL AGENT (I) IRREVOCABLY SUBMITS TO THE
JURISDICTION OF ANY NEW YORK STATE COURT OR FEDERAL COURT SITTING IN NEW YORK
CITY IN ANY ACTION ARISING OUT OF ANY LOAN DOCUMENT, (II) AGREES THAT ALL CLAIMS
IN SUCH ACTION MAY BE DECIDED IN SUCH COURT, (III) WAIVES, TO THE FULLEST EXTENT
IT MAY EFFECTIVELY DO SO, THE DEFENSE OF AN INCONVENIENT FORUM AND (IV) CONSENTS
TO THE SERVICE OF PROCESS BY MAIL. A FINAL JUDGMENT IN ANY SUCH ACTION SHALL BE
CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS. NOTHING HEREIN SHALL
AFFECT THE RIGHT OF ANY PARTY TO SERVE LEGAL PROCESS IN ANY MANNER PERMITTED BY
LAW OR AFFECT ITS RIGHT TO BRING ANY ACTION IN ANY OTHER COURT. EACH OF THE
GRANTORS AGREES THAT THE COLLATERAL AGENT SHALL HAVE THE RIGHT TO PROCEED
AGAINST SUCH GRANTOR OR ITS PROPERTY IN A COURT IN ANY LOCATION TO ENABLE THE
LENDERS TO REALIZE ON THE COLLATERAL OR ANY OTHER SECURITY FOR THE OBLIGATIONS
OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER ENTERED IN FAVOR OF THE COLLATERAL
AGENT OR THE LENDERS. EACH GRANTOR AGREES THAT IT WILL NOT ASSERT ANY PERMISSIVE
COUNTERCLAIMS IN ANY PROCEEDING BROUGHT BY THE COLLATERAL AGENT TO REALIZE ON
THE COLLATERAL OR ANY OTHER SECURITY FOR THE OBLIGATIONS, OR TO ENFORCE A
JUDGMENT OR OTHER COURT ORDER IN FAVOR OF THE COLLATERAL AGENT. EACH GRANTOR
WAIVES ANY OBJECTION THAT IT MAY HAVE TO THE LOCATION OF THE COURT IN WHICH THE
COLLATERAL AGENT MAY COMMENCE A PROCEEDING DESCRIBED IN THIS SECTION.

         9.8. Indemnity. Each Grantor hereby agrees, jointly with the other
Grantors and severally, to indemnify the Collateral Agent and its successors,
assigns, agents and employees (each, an "indemnified party"), from and against
any and all liabilities, damages, penalties, suits, costs, and expenses of any
kind and nature (including, without limitation, all expenses of litigation or
preparation therefor whether or not the Collateral Agent is a party thereto)
imposed on, incurred by or asserted against the Collateral Agent, or its
successors, assigns, agents and employees, in any way relating to or arising out
of this Security Agreement, or the ownership, delivery, possession, or other
disposition of any Collateral except to the extent that such liabilities,
damages, penalties, costs or expenses were caused by the gross negligence or
willful misconduct of such indemnified party.

         9.9. Addresses for Notices. All notices and other communications
provided for hereunder shall be in writing (including facsimile communication)
and mailed, telegraphed, telecopied, telexed, cabled or delivered, if to any
Grantors, c/o CMS Enterprises Company at its address at Fairlane Plaza South,
330 Town Center Drive, Suite 1100, Dearborn, Michigan 48126, Attention: General

         9.10. Continuing Security Interest; Assignments under Credit Agreement.
This Security Agreement shall create a continuing security interest in the
Collateral and shall (i) remain in full force and effect until the earlier to
occur of (x) the payment in full of all Obligations of the Borrower now or
hereafter existing under the Credit Agreement, whether for principal, interest,
fees, expenses or otherwise, and all other amounts payable under this Security
Agreement, and the expiration or termination of the Commitments and (y) the
release by the Lenders of their Lien on all of the Collateral, (ii) be binding
upon the Grantors, their respective successors and assigns, and (iii) inure,
together with the rights and remedies of the Collateral Agent hereunder, to the
benefit of, and be enforceable by, the Collateral Agent and its successors,
transferees and assigns. Without limiting the generality of the foregoing clause
(iii), any Lender may assign or otherwise transfer all or any portion of its
rights and obligations under the Credit Agreement (including, without
limitation, all or any portion of its Commitment, the Loans owing to it and any
Promissory Note held by it) to any other Person, and such other Person shall
thereupon become vested with all the benefits in respect thereof granted to such
Lender herein or otherwise, subject, however to the provisions of Sections 10.03
and 11.07 of the Credit Agreement. Upon the earlier to occur of (A) the payment
in full of all Obligations of the Borrower now or hereafter existing under the
Credit Agreement, whether for principal, interest, fees, expenses or otherwise,
and all other amounts payable under this Security Agreement, and the expiration
or termination of the Commitments and (B) the release by the Lenders of their
Lien on all of the Collateral, the security interest granted hereby shall
terminate and all rights to the Collateral shall revert to the Grantors. In
addition, the Collateral Agent shall release any Collateral as permitted or
required pursuant to Section 10.03 of the Credit Agreement. Upon any such
termination, the Collateral Agent will, at the Grantors' expense, return to the
Grantors such of the Collateral as shall not have been sold or otherwise applied
pursuant to the terms hereof and execute and deliver to the Grantors such
documents as any Grantor shall reasonably request to evidence such termination.

         9.11. WAIVER OF JURY TRIAL. THE GRANTORS AND THE COLLATERAL AGENT EACH
HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING
OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN
DOCUMENT, OR ANY OTHER INSTRUMENT OR DOCUMENT DELIVERED HEREUNDER OR THEREUNDER.
