                         REPRESENTATIONS AND WARRANTIES

         The Grantor represents and warrants to the Collateral Agent and the
Lenders that:

         3.1. Title, Authorization, Validity and Enforceability. The Grantor has
good and valid rights in or the power to transfer the Collateral and title to
the Collateral with respect to which it has purported to grant a security
interest hereunder, free and clear of all Liens (other than Permitted Liens),
and has full power and authority to grant to the Collateral Agent the security
interest in such Collateral pursuant hereto. The execution and delivery by the
Grantor of this Security Agreement has been duly authorized by proper corporate
or other proceedings, and this Security Agreement constitutes a legal, valid and
binding obligation of the Grantor and creates a security interest which is
enforceable against the Grantor in all now owned and hereafter acquired
Collateral. When financing statements have been filed in the appropriate offices
against the Grantor in the locations listed on Exhibit "B", the Collateral Agent
will have a fully perfected first priority security interest in the Collateral
in which a security interest may be perfected by filing.

         3.2. Conflicting Laws and Contracts. The execution, delivery and
performance by the Grantor of this Security Agreement (i) are within the
Grantor's powers, (ii) have been duly authorized by all necessary corporate or
other organizational action or proceedings and (iii) do not and will not (A)
require any consent or approval of the stockholders (or other applicable holder
of equity) of the Grantor (other than such consents and approvals which have
been obtained and are in full force and effect), (B) violate any provision of
the charter or by-laws (or other comparable constitutive documents) of the
Grantor or of law, (C) violate any legal restriction binding on or affecting the
Grantor, (D) result in a breach of, or constitute a default under, any indenture
or loan or credit agreement or any other agreement, lease or instrument to which
the Grantor is a party or by which it or its properties may be bound or
affected, or (E) result in or require the creation of any Lien (other than
pursuant to the Loan Documents as defined in each of the Credit Agreements and
the Enterprises Credit Agreement) upon or with respect to any of its properties.

         3.3. Type and Jurisdiction of Organization. The Grantor is a
corporation organized under the laws of the State of Michigan.

         3.4. Pledged Securities and Other Investment Property. Exhibit "A" sets
forth a complete and accurate list of the Instruments, Securities and other
Investment Property delivered to the Collateral Agent. The Grantor is the direct
and beneficial owner of each Instrument, Security and other type of Investment
Property listed on Exhibit "A" as being owned by it, free and clear of any
Liens, except for the security interest granted to the Collateral Agent for the
benefit of the Lenders hereunder and other Permitted Liens. The Grantor further
represents and warrants that (i) all such Securities or other types of
Investment Property which are shares of stock in a corporation or ownership
interests in a partnership or limited liability company and in which the Grantor
is granting a security

                                       4

interest pursuant to this Security Agreement have been (to the extent such
concepts are relevant with respect to such Security or other type of Investment
Property) duly and validly issued, are fully paid and non-assessable and
constitute the percentage of the issued and outstanding shares of stock (or
other equity interests) of the respective issuers thereof indicated on Exhibit
"A" hereto and (ii) with respect to any certificates delivered to the Collateral
Agent representing an ownership interest in a partnership or limited liability
company and in which the Grantor is granting a security interest pursuant to
this Security Agreement, either such certificates are Securities as defined in
Article 8 of the New York UCC of the applicable jurisdiction as a result of
actions by the issuer or otherwise, or, if such certificates are not Securities,
the Grantor has so informed the Collateral Agent so that the Collateral Agent
may take steps to perfect its security interest therein as a General Intangible.

                                   ARTICLE IV

                                    COVENANTS

         From the date of this Security Agreement, and thereafter until this
Security Agreement is terminated:

         4.1. General.

                  4.1.1 Inspection. The Grantor will permit the Collateral Agent
or any Lender, by its representatives and agents (i) to inspect the Collateral,
(ii) to examine and make copies of the records of the Grantor relating to the
Collateral and (iii) to discuss the Collateral and the related records of the
Grantor with, and to be advised as to the same by, the Grantor's officers and
employees all at such reasonable times and intervals as the Collateral Agent or
such Lender may determine.

                  4.1.2 Records and Reports. The Grantor will maintain complete
and accurate books and records with respect to the Collateral, 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. The 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 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. The Grantor will take any and all actions necessary
to defend title to the Collateral against all persons and to defend the security
interest of the Collateral Agent in the 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. The Grantor will preserve its existence as a
corporation, not change its state of organization, and not change its mailing
address, unless, in each

                                       5
<PAGE>

such case, the 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, or (y) taken such steps (with the
cooperation of the 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.

         4.2. Instruments and Securities. The Grantor will (i) deliver to the
Collateral Agent immediately upon execution of this Security Agreement the
originals of all Securities constituting Collateral (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 the Grantor (if any then exist) and (iii) hold in trust for the
Collateral Agent upon receipt and immediately thereafter deliver to the
Collateral Agent any additional Securities and Instruments constituting
Collateral.

         4.3. Uncertificated Securities and Certain Other Investment Property.
The Grantor will permit the Collateral Agent from time to time to cause the
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 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. The Grantor
will use all commercially reasonable efforts, with respect to Investment
Property constituting Collateral 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. The Grantor will permit any
registerable Collateral to be registered in the name of the Collateral Agent or
its nominee at any time at the option of the Required Secured Parties following
the occurrence and during the continuance of an Event of Default.

         4.5. Voting Rights and Dividends

                  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 Agreements, shall have
occurred and be continuing:

                  (i) Until the Collateral Agent shall have notified the Grantor
         in writing to the contrary, the Grantor shall be entitled to exercise
         or refrain from exercising any and all voting and other consensual
         rights pertaining to the Collateral 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 the 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.

                                       6
<PAGE>

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

         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 the Grantor, be received in trust for the benefit of the Collateral
         Agent, be segregated from the other property or funds of the 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 the Grantor all such proxies and other
         instruments as the Grantor may reasonably request for the purpose of
         enabling the 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 Agreements or
an Event of Default:

                  (iv) Upon written notice to the Grantor by the Collateral
         Agent, all rights of the 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.

                  (v) All dividends and interest and other property which are
         received by the 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 the Grantor
         and shall be forthwith paid over to the Collateral Agent as Collateral
         in the same form as so received (with any necessary indorsement).

remedies:

                  5.2.1 Those rights and remedies provided in this Security

                  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,

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 the 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

                                   ARTICLE VII

                   SUBORDINATION OF INTERCOMPANY INDEBTEDNESS

         7.1. The Grantor agrees that any and all claims of the 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 the Grantor ("Intercompany Indebtedness")
shall be paid or delivered directly to the Collateral Agent for application on
any of the Obligations, due or to become due, until such Obligations shall have
first been fully paid and satisfied in cash. Should any payment, distribution,
security or instrument or proceeds thereof be received by the 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, the 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 any of the
Obligations, due or not due, and, until so delivered, the same shall be held in
trust by the Grantor as the property of the Lenders.

                                  ARTICLE VIII

any obligation to do so, the Collateral Agent may perform or pay any obligation
which the Grantor has agreed to perform or pay in this Security Agreement and
the Grantor shall reimburse the Collateral Agent for any reasonable amounts paid
by the Collateral Agent pursuant to this Section 8.1. The Grantor's obligation
to reimburse the Collateral Agent pursuant to the preceding sentence shall be an
Obligation payable on demand.

         8.2. Authorization for Secured Party to Take Certain Action. The
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 and which are Securities or with
financial intermediaries holding other Investment Property as may be necessary

Agent to the Obligations and (iv) to discharge past due taxes, assessments,

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 the
Grantor of any of its obligations under this Security Agreement or under the
Credit Agreements.

         8.3. Benefit of Agreement. The terms and provisions of this Security
Agreement shall be binding upon and inure to the benefit of the Grantor, the

                                    GUARANTY
                                       FOR
                             CMS ENERGY CORPORATION

           THIS GUARANTY, dated as of July 12, 2002, is made by CMS Enterprises
Company, a Michigan corporation, CMS Gas Transmission Company, a Michigan
corporation, and CMS Generation Co., a Michigan corporation (each individually a
"GUARANTOR" and collectively, together with any additional Subsidiaries of the
Borrower that become a party to this Guaranty by executing a supplement hereto
in the form attached hereto as Annex I, the "GUARANTORS"), in favor of the
Lenders (the "LENDERS") parties to the Credit Agreements (as defined below) and
Citicorp USA, Inc. ("CUSA"), as Collateral Agent (the "COLLATERAL AGENT") for
the Lenders.

                             PRELIMINARY STATEMENTS

           (1) Barclays Bank PLC, as Administrative Agent, the Collateral Agent
and the Lenders have entered into two Amended and Restated Credit Agreements,
each dated as of July 12, 2002, one (the "SHORT TERM CREDIT AGREEMENT") maturing
March 31, 2003 and the other (the "LONG TERM CREDIT AGREEMENT") maturing
December 15, 2003 (the Short Term Credit Agreement and the Long Term Credit
Agreement, as they may hereafter be amended or otherwise modified from time to
time, being referred to herein collectively as the "CREDIT AGREEMENTS", the
terms defined therein and not otherwise defined herein being used herein as
therein defined), with CMS Energy Corporation, a corporation organized and
existing under the laws of the State of Michigan (the "BORROWER"). The
Guarantors will derive substantial direct and indirect benefit from the
transactions contemplated by the Credit Agreements.

           (2) It is a condition precedent to the effectiveness of the Credit
Agreements that the Guarantors shall have executed and delivered this Guaranty.

           NOW, THEREFORE, in consideration of the premises and in order to
induce the Lenders to make Extensions of Credit under the Credit Agreement, the
Guarantors hereby agrees as follows:

           SECTION 1. Guaranty. Each of the Guarantors hereby unconditionally
guarantees, jointly with the other Guarantors and severally, the punctual
payment when due, whether at stated maturity, by acceleration or otherwise, of
all obligations of the Borrower now or hereafter existing under the Credit
Agreements and the Promissory Notes, whether for principal, interest, fees,

<PAGE>
                                                                               2

expenses or otherwise (such obligations being the "OBLIGATIONS"), and agrees to
pay any and all expenses (including reasonable fees and expenses of counsel)
incurred by the Agents or the Lenders in enforcing any rights under this
Guaranty. Without limiting the generality of the foregoing, the Guarantor's
liability shall extend to all amounts which constitute part of the Obligations
and would be owed by the Borrower to the Collateral Agent or the Lenders under
the Credit Agreements and the Promissory Notes but for the fact that they are
unenforceable or not allowable due to the existence of a bankruptcy,
reorganization or similar proceeding involving the Borrower.

           SECTION 2. Guaranty Absolute. Each of the Guarantors guarantee,
jointly with the other Guarantors and severally, that the Obligations will be
paid strictly in accordance with the terms of the Credit Agreements and the
Promissory Notes, regardless of any law, regulation or order now or hereafter in
effect in any jurisdiction affecting any of such terms or the rights of the
Collateral Agent or the Lenders with respect thereto against the Borrower. The
obligations of the Guarantors under this Guaranty are independent of the
Obligations, and a separate action or actions may be brought and prosecuted
against any or all of the Guarantors to enforce this Guaranty, irrespective of
whether any action is brought against the Borrower or whether the Borrower is
joined in any such action or actions. The liability of each of the Guarantors
under this Guaranty shall be absolute and unconditional irrespective of:

           (a) any lack of validity or enforceability of either or both of the
Credit Agreements, the Promissory Notes, any other Loan Document, or any other
agreement or instrument relating thereto;

           (b) any change in the time, manner or place of payment of, or in any
other term of, all or any of the Obligations, or any other amendment or waiver
of or any consent to departure from either or both of the Credit Agreements, the
Promissory Notes, or any other Loan Document, including, without limitation, any
increase in the Obligations resulting from the extension of additional credit to
the Borrower or any of its Subsidiaries or otherwise;

           (c) any taking, exchange, release or non-perfection of any
collateral, or any taking, release or amendment or waiver of or consent to
departure from any other guaranty, for all or any of the Obligations;

           (d) the existence of any claim, set-off, defense or other right which
any of the Guarantors may have at any time against the Collateral Agent, any
Lender or any other Person, whether in connection with this Guaranty, the
transactions contemplated in any of the other Loan Documents, or any unrelated
transaction;

<PAGE>
                                                                               3

           (e) any manner of application of collateral, or proceeds thereof, to
all or any of the Obligations, or any manner of sale or other disposition of any
collateral for all or any of the Obligations or any other assets of the Borrower
or any of its Subsidiaries;

           (f) any change, restructuring or termination of the corporate
structure or existence of the Borrower or any of its Subsidiaries; or

           (g) any other circumstance which might otherwise constitute a defense
available to, or a discharge of, the Borrower or a guarantor.

This Guaranty shall continue to be effective or be reinstated, as the case may
be, if at any time any payment of any of the Obligations is rescinded or must
otherwise be returned by the Collateral Agent or any Lender upon the insolvency,
bankruptcy or reorganization of the Borrower or otherwise, all as though such
payment had not been made.

           SECTION 3. Rights of Contribution with Respect to Obligations.

           (a) 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
this Guaranty or any Pledge 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.

           (b) 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.

           (c) This Section 3 is intended only to define the relative rights of
the
<PAGE>
                                                                               4

Obligors, and nothing set forth in this Section 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 this Guaranty or any
Pledge Agreement.

           (d) The parties hereto acknowledge that the rights of contribution
and indemnification hereunder shall constitute assets of the Guarantors and the
other Obligors to which such contribution and indemnification is owing.

           (e) The rights of the indemnifying Obligors against 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 or expiry of the
Commitments.

           SECTION 4. Waiver. Each of the Guarantors hereby waives promptness,
diligence, notice of acceptance and any other notice with respect to any of the
Obligations and this Guaranty and any requirement that the Collateral Agent or
any Lender protect, secure, perfect or insure any security interest or lien or
any property subject thereto or exhaust any right or take any action against the
Borrower or any other Person or any collateral.

           SECTION 5. Subrogation; Subordination of Intercompany Indebtedness.

           (a) Subrogation. Notwithstanding any payment or payments made by any
Guarantor hereunder, or any setoff or application of funds of any Guarantor by
the Collateral Agent or any Lender, each Guarantor hereby irrevocably waives any
and all rights of subrogation to the rights of the Collateral Agent and the
Lenders against the Borrower and any and all rights of reimbursement,
assignment, indemnification or implied contract or any similar rights against
the Borrower or against any endorser or other guarantor of all or any part of
the Obligations until the Lenders' claims with respect to the Obligations have
been paid in full and the Commitments terminated. If, notwithstanding the
foregoing, any amount shall be paid to any Guarantor on account of such
subrogation rights at any time when all of the Obligations shall not have been
paid in full, such amount shall be held by such Guarantor in trust for the
Collateral Agent and the Lenders, segregated from other funds of such Guarantor,
and shall, forthwith upon receipt by such Guarantor, be turned over to the
Collateral Agent in the exact form received by such Guarantor (duly endorsed by
such Guarantor to the Collateral Agent), to be applied against 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.

<PAGE>
                                                                               5

           (b) Subordination of Intercompany Indebtedness. Each Guarantor agrees
that any and all claims of any Guarantor against the Borrower or any other
Obligor 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 the obligation of Enterprises under the Enterprises Credit
Agreement. If all or any part of the assets of any Obligor, or the proceeds
thereof, are subject to any distribution, division or application to the
creditors of such Obligor, 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 Obligor is dissolved or if
substantially all of the assets of any such Obligor 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 Obligor to any other Obligor ("Intercompany
Indebtedness") shall be paid or delivered directly to the Collateral Agent for
application to the obligations, whether matured or unmatured, of Enterprises
under the Enterprises Credit Agreement, and, after the Enterprises Credit
Agreement shall have been fully paid and satisfied in cash, 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. Should any
payment, distribution, security or instrument or proceeds thereof be received by
any Obligor 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 Obligor 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, of Enterprises under the Enterprises Credit
Agreement, and, after the Enterprises Credit Agreement shall have been fully
paid and satisfied in cash, 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 Obligor as the property of the Lenders.

           SECTION 6. Representations and Warranties. Each Guarantor hereby
represents and warrants as follows:

           (a) Such Guarantor is a corporation duly organized, validly existing
<PAGE>

           (b) The execution, delivery and performance by such Guarantor of this
Guaranty (i) are within such Guarantor's powers, (ii) have been duly authorized
by all necessary corporate or other organizational action or proceedings and

stockholders (or other applicable holder of equity) of such Guarantor (other
than such consents and approvals which have been obtained and are in full force
and effect), (B) violate any provision of the charter or by-laws (or other
comparable constitutive documents) of such Guarantor or of law, (C) violate any
legal restriction binding on or affecting such Guarantor, (D) result in a breach
of, or constitute a default under, any indenture or loan or credit agreement or
any other agreement, lease or instrument to which such Guarantor is a party or

require the creation of any Lien (other than pursuant to the Loan Documents).

           (c) This Guaranty constitutes the legal, valid and binding obligation
of such Guarantor enforceable against such Guarantor in accordance with its
terms; subject to the qualification, however, that the enforcement of the rights
and remedies herein is subject to bankruptcy and other similar laws of general
application affecting rights and remedies of creditors and the application of
general principles of equity (regardless of whether considered in a proceeding
in equity or at law).

           (d) No authorization or approval or other action by, and no notice to
or filing with, any governmental authority or regulatory body is required for

now or hereafter existing under this Guaranty, whether or not such Lender shall
have made any demand under this Guaranty and although such obligations may be

transfer all or any portion of its rights and obligations under either of the
Credit Agreements (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,

Agreement.

           SECTION 12. Waiver of Jury Trial. EACH OF THE GUARANTORS AND THE
COLLATERAL AGENT HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY

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 GUARANTOR
WAIVES ANY OBJECTION THAT IT MAY HAVE TO THE LOCATION OF THE COURT IN WHICH THE
