                          MATERIAL SUBSIDIARY GUARANTY


         This Material Subsidiary Guaranty is entered into as of October 7, 1999
by Flowserve FCD Corporation, a Delaware corporation, Flowserve FSD Corporation,
a Delaware corporation, Flowserve RED Corporation, a Delaware corporation and
Flowserve International, Inc., a Delaware corporation, (collectively,
"Subsidiary Guarantors"), jointly and severally, in favor of and for the benefit
of Bank of America, N.A., as Administrative Agent for and representative of (in
such capacity herein called "Administrative Agent") itself, the Banks and the
Issuing Bank (as each such term is defined in the Credit Agreement referenced
below).

                                    RECITALS

         A. Flowserve Corporation, a New York corporation (the "Borrower") is
entering into that certain Credit Agreement dated as of October 7, 1999 entered
into by and among Borrower, the banks from time to time party thereto, Bank of
America, N.A., as Administrative Agent and Issuing Bank, Bank One, Texas, N.A.,
as Syndication Agent and ABN Amro Bank N.V., as Documentation Agent (as
extended, renewed, amended or restated from time to time, the "Credit
Agreement;" the terms defined therein being used herein as therein defined).

         B. A portion of the proceeds of the Loans may be loaned to the
Subsidiary Guarantors and Letters of Credit may be issued for the benefit of the
Subsidiary Guarantors and thus the Guarantied Obligations (as hereinafter
defined) are being incurred for and will inure to the benefit of the Subsidiary
Guarantors (which benefits are hereby acknowledged).

         C. It is a condition precedent to the making of the Loans and issuance
of Letters of Credit that Borrower's obligations under the Credit Agreement be
guarantied by the Subsidiary Guarantors.

         D. Subsidiary Guarantors are willing irrevocably and unconditionally to
guaranty such obligations of Borrower.

         NOW, THEREFORE, based upon the foregoing and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, and
in order to induce Banks, the Issuing Bank and Administrative Agent to make the
Loans and issue Letters of Credit, the Subsidiary Guarantors hereby agree as
follows:

                             SECTION 1. DEFINITIONS

         1.1 Certain Defined Terms. As used in this Subsidiary Guaranty, the
following terms shall have the following meanings unless the context otherwise
requires:

         "Guarantied Obligations" has the meaning assigned to that term in
Section 2.1.

         "Payment in full", "paid in full" or any similar term means payment in
full of the Guarantied Obligations including, without limitation, all principal,
interest, costs, fees and expenses (including, without limitation, legal fees
and expenses) of Banks and Administrative Agent as required under the Loan
Documents.

         "Subsidiary Guaranty" means this Subsidiary Guaranty.

         1.2 Interpretation.

         (a) References to "Sections" shall be to Sections of this Subsidiary
Guaranty unless otherwise specifically provided. All accounting terms not
otherwise defined herein shall have the meanings assigned to them under
generally accepted accounting principles.

         (b) In the event of any conflict or inconsistency between the terms,
conditions and provisions of this Subsidiary Guaranty and the terms, conditions
and provisions of the Credit Agreement, the terms, conditions and provisions of
this Subsidiary Guaranty shall prevail.

                             SECTION 2. THE GUARANTY

         2.1 Guaranty of the Guarantied Obligations. Subsidiary Guarantors
hereby irrevocably and unconditionally guaranty, as primary obligor and not
merely as surety, the due and punctual payment in full of all Guarantied
Obligations when the same shall become due, whether at stated maturity, by
required prepayment, declaration, acceleration, demand or otherwise (including
amounts that would become due but for the operation of the automatic stay under
Section 362(a) of the Bankruptcy Code, 11 U.S.C. ss. 362(a)). The term
"Guarantied Obligations" is used herein in its most comprehensive sense and
includes:

         (a) any and all Obligations of Borrower now or hereafter made, incurred
or created, whether absolute or contingent, liquidated or unliquidated, whether
due or not due, and however arising under or in connection with the Credit
Agreement and the other Loan Documents, including those arising under successive
borrowing transactions under the Credit Agreement which shall either continue
the Obligations of Borrower or from time to time renew them after they have been
satisfied; and

         (b) those expenses set forth in Section 2.9 hereof.

         2.2 Limitation on Amount Guarantied; Contribution by Subsidiary
Guarantors.

         (a) Anything contained in this Subsidiary Guaranty to the contrary
notwithstanding, if any Fraudulent Transfer Law (as hereinafter defined) is
determined by a court of competent jurisdiction to be applicable to the
obligations of the Subsidiary Guarantors under this Subsidiary Guaranty, such
obligations of the Subsidiary Guarantors hereunder shall be limited to a maximum
aggregate amount equal to the largest amount that would not render their
obligations hereunder subject to avoidance as a fraudulent transfer or
conveyance under Section 548 of Title 11 of the United States Code or any
applicable provisions of comparable state law (collectively, the "Fraudulent
Transfer Laws"), in each case after giving effect to all other liabilities of
the Subsidiary Guarantors, contingent or otherwise, that are relevant under the
Fraudulent Transfer Laws (specifically excluding, however, any liabilities of
the Subsidiary Guarantors (x) in respect of intercompany indebtedness to
Borrower or other affiliates of Borrower to the extent that such indebtedness
would be discharged in an amount equal to the amount paid by the Subsidiary
Guarantors hereunder and (y) under any guaranty of Subordinated Indebtedness
which guaranty contains a limitation as to maximum amount similar to that set
forth in this Section 2.2(a), pursuant to which the liability of the Subsidiary
Guarantors hereunder is included in the liabilities taken into account in
determining such maximum amount) and after giving effect as assets to the value
(as determined under the applicable provisions of the Fraudulent Transfer Laws)
of any rights to subrogation, reimbursement, indemnification or contribution of
the Subsidiary Guarantors pursuant to applicable law or pursuant to the terms of
any agreement (including without limitation any such right of contribution under
a Related Guaranty (as hereinafter defined) as contemplated by Section 2.2(b)).

         (b) Subsidiary Guarantors under this Subsidiary Guaranty, and each
guarantor under other guaranties, if any, relating to the Credit Agreement (the
"Related Guaranties") which contain a contribution provision similar to that set
forth in this Section 2.2(b), together desire to allocate among themselves
(collectively, the "Contributing Guarantors"), in a fair and equitable manner,
their obligations arising under this Subsidiary Guaranty and the Related
Guaranties. Accordingly, in the event any payment or distribution is made on any
date by the Subsidiary Guarantors under this Subsidiary Guaranty or a guarantor
under a Related Guaranty (a "Funding Guarantor") that exceeds its Fair Share (as
defined below) as of such date, that Funding Guarantor shall be entitled to a
contribution from each of the other Contributing Guarantors in the amount of
such other Contributing Guarantor's Fair Share Shortfall (as defined below) as
of such date, with the result that all such contributions will cause each
Contributing Guarantor's Aggregate Payments (as defined below) to equal its Fair
Share as of such date. "Fair Share" means, with respect to a Contributing
Guarantor as of any date of determination, an amount equal to (i) the ratio of
(x) the Adjusted Maximum Amount (as defined below) with respect to such
Contributing Guarantor to (y) the aggregate of the Adjusted Maximum Amounts with
respect to all Contributing Guarantors, multiplied by (ii) the aggregate amount
paid or distributed on or before such date by all Funding Guarantors under this
Subsidiary Guaranty and the Related Guaranties in respect of the obligations
guarantied. "Fair Share Shortfall" means, with respect to a Contributing
Guarantor as of any date of determination, the excess, if any, of the Fair Share
of such Contributing Guarantor over the Aggregate Payments of such Contributing
Guarantor. "Adjusted Maximum Amount" means, with respect to a Contributing
Guarantor as of any date of determination, the maximum aggregate amount of the
obligations of such Contributing Guarantor under this Subsidiary Guaranty and
the Related Guaranties, determined as of such date in accordance with Section
2.2(a) or, if applicable, a similar provision contained in a Related Guaranty;
provided that, solely for purposes of calculating the "Adjusted Maximum Amount"
with respect to any Contributing Guarantor for purposes of this Section 2.2(b),
any assets or liabilities of such Contributing Guarantor arising by virtue of
any rights to subrogation, reimbursement or indemnification or any rights to or
obligations of contribution hereunder or under any similar provision contained
in a Related Guaranty shall not be considered as assets or liabilities of such
Contributing Guarantor. "Aggregate Payments" means, with respect to a
Contributing Guarantor as of any date of determination, an amount equal to (i)
the aggregate amount of all payments and distributions made on or before such
date by such Contributing Guarantor in respect of this Subsidiary Guaranty and
the Related Guaranties (including, without limitation, in respect of this
Section 2.2(b) or any similar provision contained in a Related Guaranty) minus
(ii) the aggregate amount of all payments received on or before such date by
such Contributing Guarantor from the other Contributing Guarantors as
contributions under this Section 2.2(b) or any similar provision contained in a
Related Guaranty. The amounts payable as contributions hereunder and under
similar provisions in the Related Guaranties shall be determined as of the date
on which the related payment or distribution is made by the applicable Funding
Guarantor. The allocation among Contributing Guarantors of their obligations as
set forth in this Section 2.2(b) or any similar provision contained in a Related
Guaranty shall not be construed in any way to limit the liability of any
Contributing Guarantor hereunder or under a Related Guaranty. Each Contributing
Guarantor under a Related Guaranty is a third party beneficiary to the
contribution agreement set forth in this Section 2.2(b).

         2.3 Liability of Subsidiary Guarantors. Subsidiary Guarantors agree
that their obligations hereunder are irrevocable, absolute, independent and
unconditional and shall not be affected by any circumstance which constitutes a
legal or equitable discharge of a guarantor or surety other than indefeasible
payment in full of the Guarantied Obligations, the termination of the
Commitments, and the expiration or cancellation of all Letters of Credit. In
furtherance of the foregoing and without limiting the generality thereof, the
Subsidiary Guarantors agree as follows:





                                      -3-
<PAGE>   4

         (a) This Subsidiary Guaranty is a guaranty of payment when due and not
of collectibility.

         (b) Administrative Agent may enforce this Subsidiary Guaranty upon the
occurrence of an Event of Default under the Credit Agreement notwithstanding the
existence of any dispute between Banks and Borrower with respect to the
existence of such Event of Default.

         (c) The obligations of the Subsidiary Guarantors hereunder are
independent of the obligations of Borrower under the Loan Documents and the
obligations of any other guarantor of the obligations of Borrower under the Loan
Documents, and a separate action or actions may be brought and prosecuted
against the Subsidiary Guarantors whether or not any action is brought against
Borrower or any of such other guarantors and whether or not Borrower is joined
in any such action or actions.

         (d) Subsidiary Guarantors payment of a portion, but not all, of the
Guarantied Obligations shall in no way limit, affect, modify or abridge the
Subsidiary Guarantors' liability for any portion of the Guarantied Obligations
which has not been paid. Without limiting the generality of the foregoing, if
Administrative Agent is awarded a judgment in any suit brought to enforce the
Subsidiary Guarantors covenant to pay a portion of the Guarantied Obligations,
such judgment shall not be deemed to release the Subsidiary Guarantors from
their covenant to pay the portion of the Guarantied Obligations that is not the
subject of such suit.

         (e) Administrative Agent or any Bank, upon such terms as it deems
appropriate, without notice or demand and without affecting the validity or
enforceability of this Subsidiary Guaranty or giving rise to any reduction,
limitation, impairment, discharge or termination of the Subsidiary Guarantors'
liability hereunder, from time to time may (i) renew, extend, accelerate,
increase the rate of interest on, or otherwise change the time, place, manner or
terms of payment of the Guarantied Obligations, (ii) settle, compromise, release
or discharge, or accept or refuse any offer of performance with respect to, or
substitutions for, the Guarantied Obligations or any agreement relating thereto
and/or subordinate the payment of the same to the payment of any other
obligations; (iii) request and accept other guaranties of the Guarantied
Obligations and take and hold security for the payment of this Subsidiary
Guaranty or the Guarantied Obligations; (iv) release, surrender, exchange,
substitute, compromise, settle, rescind, waive, alter, subordinate or modify,
with or without consideration, any security for payment of the Guarantied
Obligations, any other guaranties of the Guarantied Obligations, or any other
obligation of any Person with respect to the Guarantied Obligations; (v) enforce
and apply any security now or hereafter held by or for the benefit of
Administrative Agent or any Bank in respect of this Subsidiary Guaranty or the
Guarantied Obligations and direct the order or manner of sale thereof, or
exercise any other right or remedy that Administrative Agent or Banks, or any of
them, may have against any such security, as Administrative Agent in its
discretion may determine consistent with the Credit Agreement and any applicable
security agreement, including foreclosure on any such security pursuant to one
or more judicial or nonjudicial sales, whether or not every aspect of any such
sale is commercially reasonable, and even though such action operates to impair
or extinguish any right of reimbursement or subrogation or other right or remedy
of the Subsidiary Guarantors against Borrower or any security for the Guarantied
Obligations; and (vi) exercise any other rights available to it under the Loan
Documents.

         (f) This Subsidiary Guaranty and the obligations of the Subsidiary
Guarantors hereunder shall be valid and enforceable and shall not be subject to
any reduction, limitation, impairment, discharge or termination for any reason
(other than indefeasible payment in full of the Guarantied Obligations, the
termination of the Commitments, and the expiration or cancellation of all
Letters of Credit), including without limitation the occurrence of any of the
following, whether or not


                                      -4-
<PAGE>   5

the Subsidiary Guarantors shall have had notice or knowledge of any of them: (i)
any failure or omission to assert or enforce or agreement or election not to
assert or enforce, or the stay or enjoining, by order of court, by operation of
law or otherwise, of the exercise or enforcement of, any claim or demand or any
right, power or remedy (whether arising under the Loan Documents, at law, in
equity or otherwise) with respect to the Guarantied Obligations or any agreement
relating thereto, or with respect to any other guaranty of or security for the
payment of the Guarantied Obligations; (ii) any rescission, waiver, amendment or
modification of, or any consent to departure from, any of the terms or
provisions (including without limitation provisions relating to events of
default) of the Credit Agreement, any of the other Loan Documents or any
agreement or instrument executed pursuant thereto, or of any other guaranty or
security for the Guarantied Obligations, in each case whether or not in
accordance with the terms of the Credit Agreement or such Loan Document or any
agreement relating to such other guaranty or security; (iii) the Guarantied
Obligations, or any agreement relating thereto, at any time being found to be
illegal, invalid or unenforceable in any respect; (iv) the application of
payments received from any source (other than payments received pursuant to the
other Loan Documents or from the proceeds of any security for the Guarantied
Obligations, except to the extent such security also serves as collateral for
indebtedness other than the Guarantied Obligations) to the payment of
indebtedness other than the Guarantied Obligations, even though Administrative
Agent or Banks, or any of them, might have elected to apply such payment to any
part or all of the Guarantied Obligations; (v) any Bank's or Administrative
Agent's consent to the change, reorganization or termination of the corporate
structure or existence of Borrower or any of its Subsidiaries and to any
corresponding restructuring of the Guarantied Obligations; (vi) any failure to
perfect or continue perfection of a security interest in any collateral which
secures any of the Guarantied Obligations; (vii) any defenses, set-offs or
counterclaims which Borrower may allege or assert against Administrative Agent
or any Bank in respect of the Guarantied Obligations, including but not limited
to failure of consideration, breach of warranty, payment, statute of frauds,
statute of limitations, accord and satisfaction and usury; and (viii) any other
act or thing or omission, or delay to do any other act or thing, which may or
might in any manner or to any extent vary the risk of the Subsidiary Guarantors
as an obligor in respect of the Guarantied Obligations.

         2.4 Waivers by Subsidiary Guarantors. Subsidiary Guarantors hereby
waive, for the benefit of Banks and Administrative Agent:

         (a) any right to require Administrative Agent or Banks, as a condition
of payment or performance by the Subsidiary Guarantors, to (i) proceed against
Borrower, any other guarantor of the Guarantied Obligations or any other Person,
(ii) proceed against or exhaust any security held from Borrower, any other
guarantor of the Guarantied Obligations or any other Person, (iii) proceed
against or have resort to any balance of any deposit account or credit on the
books of Administrative Agent or any Bank in favor of Borrower or any other
Person, or (iv) pursue any other remedy in the power of Administrative Agent or
any Bank whatsoever;

         (b) any defense arising by reason of the incapacity, lack of authority
or any disability or other defense of Borrower including, without limitation,
any defense based on or arising out of the lack of validity or the
unenforceability of the Guarantied Obligations or any agreement or instrument
relating thereto or by reason of the cessation of the liability of Borrower from
any cause other than indefeasible payment in full of the Guarantied Obligations,
the termination of the Commitments, and the expiration or cancellation of all
Letters of Credit;

         (c) any defense based upon any statute or rule of law which provides
that the obligation of a surety must be neither larger in amount nor in other
respects more burdensome than that of the principal;



                                      -5-
<PAGE>   6

         (d) any defense based upon Administrative Agent's or any Bank's errors
or omissions in the administration of the Guarantied Obligations, except
behavior which amounts to bad faith;

         (e) (i) any principles or provisions of law, statutory or otherwise,
which are or might be in conflict with the terms of this Subsidiary Guaranty and
any legal or equitable discharge of the Subsidiary Guarantors' obligations
hereunder, (ii) the benefit of any statute of limitations affecting the
Subsidiary Guarantors' liability hereunder or the enforcement hereof, (iii) any
rights to set-offs, recoupments and counterclaims, and (iv) promptness,
diligence and any requirement that Administrative Agent or any Bank protect,
secure, perfect or insure any security interest or lien or any property subject
thereto;

         (f) notices, demands, presentments, protests, notices of protest,
notices of dishonor and notices of any action or inaction, including acceptance
of this Subsidiary Guaranty, notices of default under the Credit Agreement or
any agreement or instrument related thereto, notices of any renewal, extension
or modification of the Guarantied Obligations or any agreement related thereto,
notices of any extension of credit to Borrower and notices of any of the matters
referred to in Section 2.3 and any right to consent to any thereof; and

         (g) any defenses or benefits that may be derived from or afforded by
law which limit the liability of or exonerate guarantors or sureties, or which
may conflict with the terms of this Subsidiary Guaranty.

         2.5 Payment by Subsidiary Guarantors; Application of Payments.
Subsidiary Guarantors hereby agree, in furtherance of the foregoing and not in
limitation of any other right which Administrative Agent or any other Person may
have at law or in equity against the Subsidiary Guarantors by virtue hereof,
upon the failure of Borrower to pay any of the Guarantied Obligations when and
as the same shall become due, whether at stated maturity, by required
prepayment, declaration, acceleration, demand or otherwise (including amounts
that would become due but for the operation of the automatic stay under Section
362(a) of the Bankruptcy Code, 11 U.S.C. ss. 362(a)), the Subsidiary Guarantors
will forthwith pay, or cause to be paid, in cash, to Administrative Agent for
the ratable benefit of Banks, an amount equal to the sum of the unpaid principal
amount of all Guarantied Obligations then due as aforesaid, accrued and unpaid
interest on such Guarantied Obligations (including, without limitation, interest
which, but for the filing of a petition in bankruptcy with respect to Borrower,
would have accrued on such Guarantied Obligations, whether or not a claim is
allowed against Borrower for such interest in any such bankruptcy proceeding)
and all other Guarantied Obligations then owed to Administrative Agent and/or
Banks as aforesaid. All such payments shall be applied promptly from time to
time by Administrative Agent:

         First, to the payment of the costs and expenses of any collection or
other realization under this Subsidiary Guaranty, including reasonable
compensation to Administrative Agent and its agents and counsel, and all
expenses, liabilities and Loans made or incurred by Administrative Agent in
connection therewith;

         Second, to the payment of all other Guarantied Obligations; and

         Third, after payment in full of all Guarantied Obligations, to the
payment to the Subsidiary Guarantors, or their successors or assigns, or to
whomsoever may be lawfully entitled to receive the same or as a court of
competent jurisdiction may direct, of any surplus then remaining from such
payments.



                                      -6-
<PAGE>   7

         2.6 Subrogation. Until the Guarantied Obligations shall have been
indefeasibly paid in full and the Commitments shall have terminated and all
Letters of Credit shall have expired or been cancelled or cash collateralized
pursuant to the terms of the Credit Agreement, the Subsidiary Guarantors shall
withhold exercise of (a) any right of subrogation, (b) any right of contribution
the Subsidiary Guarantors may have against any other guarantor of the Guarantied
Obligations, (c) any right to enforce any remedy which Administrative Agent or
any Bank now has or may hereafter have against Borrower or (d) any benefit of,
and any right to participate in, any security now or hereafter held by
Administrative Agent or any Bank. Subsidiary Guarantors further agree that, to
the extent the waiver of its rights of subrogation and contribution as set forth
herein is found by a court of competent jurisdiction to be void or voidable for
any reason, any rights of subrogation the Subsidiary Guarantors may have against
Borrower or against any collateral or security, and any rights of contribution
the Subsidiary Guarantors may have against any other guarantor, shall be junior
and subordinate to any rights Administrative Agent or Banks may have against
Borrower, to all right, title and interest Administrative Agent or Banks may
have in any such collateral or security, and to any right Administrative Agent
or Banks may have against such other guarantor. Administrative Agent, on behalf
of Banks, may use, sell or dispose of any item of collateral or security as it
sees fit without regard to any subrogation rights the Subsidiary Guarantors may
have, and upon any such disposition or sale any rights of subrogation the
Subsidiary Guarantors may have shall terminate. If any amount shall be paid to
the Subsidiary Guarantors on account of such subrogation rights at any time when
all Guarantied Obligations shall not have been paid in full, such amount shall
be held in trust for Administrative Agent on behalf of Banks and shall forthwith
be paid over to Administrative Agent for the benefit of Banks to be credited and
applied against the Guarantied Obligations, whether matured or unmatured, in
accordance with the terms of the Credit Agreement or any applicable security
agreement.

         2.7 Subordination of Other Obligations. Any indebtedness of Borrower
now or hereafter held by the Subsidiary Guarantors is hereby subordinated in
right of payment to the Guarantied Obligations, and any such indebtedness of
Borrower to the Subsidiary Guarantors collected or received by the Subsidiary
Guarantors after an Event of Default has occurred and is continuing shall be
held in trust for Administrative Agent on behalf of Banks and shall forthwith be
paid over to Administrative Agent for the benefit of Banks to be credited and
applied against the Guarantied Obligations but without affecting, impairing or
limiting in any manner the liability of the Subsidiary Guarantors under any
other provision of this Subsidiary Guaranty.

         2.8 Real Property Security. Subsidiary Guarantors agree that, if all or
a portion of the Guarantied Obligations are at any time secured by a deed of
trust or mortgage covering interests in real property, Administrative Agent or
its designee, in its sole discretion, without notice or demand and without
affecting the liability of the Subsidiary Guarantors under this Subsidiary
Guaranty, may foreclose, pursuant to the terms of the Loan Documents or
otherwise, on such deed of trust or mortgage and the interests in real property
secured thereby by nonjudicial or other sale. The Subsidiary Guarantors
understand that the exercise by Banks or Administrative Agent, or any of them,
of certain rights and remedies contained in the Credit Agreement and such deed
of trust or mortgage may affect or eliminate Subsidiary Guarantors' right of
subrogation against Borrower and that the Subsidiary Guarantors may therefore
incur a partially or totally nonreimbursable liability hereunder. Nevertheless,
the Subsidiary Guarantors hereby authorize and empower Administrative Agent and
any Bank to exercise, in its sole discretion, any rights and remedies, or any
combination thereof, which may then be available, since it is the intent and
purpose of the Subsidiary Guarantors that the obligations hereunder shall be
absolute, independent and unconditional under any and all circumstances.
Notwithstanding any foreclosure of the lien of such deed of trust or mortgage
with respect to any or all real or personal property secured thereby, whether by
the exercise of the power of sale contained therein, by an action



                                      -7-
<PAGE>   8

for judicial foreclosure or by an acceptance of a deed in lieu of foreclosure,
the Subsidiary Guarantors shall remain bound under this Subsidiary Guaranty,
including its obligation to pay any deficiency after a nonjudicial foreclosure.

         2.9 Expenses. Subsidiary Guarantors agree to pay, or cause to be paid,
and to save Administrative Agent and Banks harmless against liability for, any
and all costs and expenses (including fees and disbursements of counsel and the
allocated cost of inhouse counsel for the Administrative Agent) incurred or
expended by Administrative Agent or any Bank in connection with the enforcement
of or preservation of any rights under this Subsidiary Guaranty.

         2.10 Continuing Guaranty; Termination of Subsidiary Guaranty. This
Subsidiary Guaranty is a continuing guaranty and shall remain in effect until
all of the Guarantied Obligations shall have been indefeasibly paid in full, the
Commitments shall have terminated and all Letters of Credit shall have expired
or been cancelled or cash collateralized pursuant to the terms of the Credit
Agreement. Anything contained in this Subsidiary Guaranty to the contrary
notwithstanding, this Subsidiary Guaranty shall not apply to Guarantied
Obligations created after actual receipt by Administrative Agent of written
notice (delivered in accordance with Section 5.2) from the Subsidiary Guarantors
of its revocation as to future transactions; provided, however, that any such
revocation shall not affect the Subsidiary Guarantors' liability for any
Guarantied Obligations outstanding at the time of receipt of such notice or any
extension or renewal of such Guarantied Obligations.

         2.11 Authority of the Subsidiary Guarantors or Borrower. It is not
necessary for Banks or Administrative Agent to inquire into the capacity or
powers of the Subsidiary Guarantors or Borrower or the officers, directors or
any agents acting or purporting to act on behalf of any of them.

         2.12 Financial Condition of Borrower. Any Loans may be granted to
Borrower or continued from time to time without notice to or authorization from
the Subsidiary Guarantors regardless of the financial or other condition of
Borrower at the time of any such grant or continuation. Banks and Administrative
Agent shall have no obligation to disclose or discuss with the Subsidiary
Guarantors their assessment, or the Subsidiary Guarantors' assessments, of the
financial condition of Borrower. Subsidiary Guarantors have adequate means to
obtain information from Borrower on a continuing basis concerning the financial
condition of Borrower and its ability to perform its obligations under the
Credit Agreement, and the Subsidiary Guarantors assume the responsibility for
being and keeping informed of the financial condition of Borrower and of all
circumstances bearing upon the risk of nonpayment of the Guarantied Obligations.
Subsidiary Guarantors hereby waive and relinquish any duty on the part of
Administrative Agent or any Bank to disclose any matter, fact or thing relating
to the business, operations or conditions of Borrower now known or hereafter
known by Administrative Agent or any Bank.

         2.13 Rights Cumulative. The rights, powers and remedies given to Banks
and Administrative Agent by this Subsidiary Guaranty are cumulative and shall be
in addition to and independent of all rights, powers and remedies given to Banks
and Administrative Agent by virtue of any statute or rule of law or in any of
the other Loan Documents or any agreement between the Subsidiary Guarantors and
Banks and/or Administrative Agent or between Borrower and Banks and/or
Administrative Agent. Any forbearance or failure to exercise, and any delay by
any Bank or Administrative Agent in exercising, any right, power or remedy
hereunder shall not impair any such right, power or remedy or be construed to be

         2.14 Bankruptcy; Post-Petition Interest; Reinstatement of Subsidiary
Guaranty.

         (a) The obligations of the Subsidiary Guarantors under this Subsidiary
Guaranty shall not be reduced, limited, impaired, discharged, deferred,
suspended or terminated by any proceeding, voluntary or involuntary, involving
the bankruptcy, insolvency, receivership, reorganization, liquidation or
arrangement of Borrower or by any defense which Borrower may have by reason of
the order, decree or decision of any court or administrative body resulting from
any such proceeding.

         (b) Subsidiary Guarantors acknowledge and agree that any interest on
any portion of the Guarantied Obligations which accrues after the commencement
of any proceeding referred to in clause (a) above (or, if interest on any
portion of the Guarantied Obligations ceases to accrue by operation of law by
reason of the commencement of said proceeding, such interest as would have
accrued on such portion of the Guarantied Obligations if said proceedings had
not been commenced) shall be included in the Guarantied Obligations because it
is the intention of the Subsidiary Guarantors and Administrative Agent that the
Guarantied Obligations which are guarantied by the Subsidiary Guarantors
pursuant to this Subsidiary Guaranty should be determined without regard to any
rule of law or order which may relieve Borrower of any portion of such
Guarantied Obligations. Subsidiary Guarantors will permit any trustee in
bankruptcy, receiver, debtor in possession, assignee for the benefit of
creditors or similar person to pay Administrative Agent, or allow the claim of
Administrative Agent in respect of, any such interest accruing after the date on
which such proceeding is commenced.

         (c) In the event that all or any portion of the Guarantied Obligations
are paid by Borrower, the obligations of the Subsidiary Guarantors hereunder
shall continue and remain in full force and effect or be reinstated, as the case
may be, in the event that all or any part of such payment(s) are rescinded or
recovered directly or indirectly from Administrative Agent or any Bank as a
preference, fraudulent transfer or otherwise, and any such payments which are so
rescinded or recovered shall constitute Guarantied Obligations for all purposes
under this Subsidiary Guaranty.

         2.15 Set Off. In addition to any other rights any Bank or
Administrative Agent may have under law or in equity, if any amount shall at any
time be due and owing by the Subsidiary Guarantors to any Bank or Administrative
Agent under this Subsidiary Guaranty, such Bank or Administrative Agent is
authorized at any time or from time to time, without notice (any such notice
being hereby expressly waived), to set off and to appropriate and to apply any
and all deposits (general or special, including but not limited to indebtedness
evidenced by certificates of deposit, whether matured or unmatured) and any
other indebtedness of any Bank or Administrative Agent owing to the Subsidiary
Guarantors and any other property of the Subsidiary Guarantors held by any Bank
or Administrative Agent to or for the credit or the account of the Subsidiary
Guarantors against and on account of the Guarantied Obligations and liabilities
of the Subsidiary Guarantors to any Bank or Administrative Agent under this
Subsidiary Guaranty.

         2.16 Discharge of Subsidiary Guaranty Upon Sale of the Subsidiary
Guarantors. If all of the stock of the Subsidiary Guarantors or any of their
successors in interest under this Subsidiary Guaranty shall be sold or otherwise
disposed of (including by merger or consolidation) in an asset sale not
prohibited by the Credit Agreement or otherwise consented to by Requisite Banks,
the Subsidiary Guaranty of the Subsidiary Guarantors or such successor in
interest, as the case may be, hereunder shall automatically be discharged and
released without any further action by Administrative Agent or any Bank or any
other Person effective as of the time of such asset sale. Notwithstanding the
foregoing, so long as the Subsidiary Guarantors or their successor shall remain
a Subsidiary of the Borrower and any Guarantied Obligations remain outstanding,
such the Subsidiary Guarantors or successor shall enter into a new Subsidiary
Guaranty with the Administrative Agent for the benefit of the Banks.

                    SECTION 3. REPRESENTATIONS AND WARRANTIES

         In order to induce Banks and Administrative Agent to accept this
Subsidiary Guaranty and to enter into the Credit Agreement and to make the Loans
thereunder, the Subsidiary Guarantors hereby represent and warrant to Banks that
the following statements are true and correct:

         3.1 Corporate Existence. Each of the Subsidiary Guarantors is duly
organized, validly existing and in good standing under the laws of the state of
its incorporation, has the corporate power to own its assets and to transact the
business in which it is now engaged and is duly qualified as a foreign
corporation and in good standing under the laws of each jurisdiction where its
ownership or lease of property or the conduct of its business requires such
qualification, except for failures to be so qualified, authorized or licensed
that would not in the aggregate have a material adverse effect on the business,
operations, assets or financial condition of each respective Subsidiary
Guarantor.

         3.2 Corporate Power; Authorization; Enforceable Obligations. Each of
the Subsidiary Guarantors has the corporate power, authority and legal right to
execute, deliver and perform this Subsidiary Guaranty and all obligations
required hereunder and has taken all necessary corporate action to authorize its
Subsidiary Guaranty hereunder on the terms and conditions hereof and its
execution, delivery and performance of this Subsidiary Guaranty and all
obligations required hereunder. No consent of any other Person including,
without limitation, stockholders and creditors of each of the Subsidiary
Guarantors (other than those which have been obtained), and no license, permit,
approval or authorization of, exemption by, notice or report to, or
registration, filing or declaration with, any governmental authority is required
by each of the Subsidiary Guarantors in connection with this Subsidiary Guaranty
or the execution, delivery, performance, validity or enforceability of this
Subsidiary Guaranty and all obligations required hereunder except such consents
licenses, permits, approvals or authorizations which, if not obtained, either
(i) would not adversely affect the ability of each of the Subsidiary Guarantors
to perform the transactions contemplated by this Subsidiary Guaranty, or (ii)
would not have a Material Adverse Effect. This Subsidiary Guaranty has been, and
each instrument or document required hereunder will be, executed and delivered
by a duly authorized officer of each of the Subsidiary Guarantors, and this
Subsidiary Guaranty constitutes, and each instrument or document required
hereunder when executed and delivered hereunder will constitute, the legally
valid and binding obligation of each of the Subsidiary Guarantors, enforceable
against each of the Subsidiary Guarantors in accordance with its terms, except
as enforcement may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws or equitable principles
relating to or limiting creditors' rights generally.

         3.3 No Legal Bar to this Subsidiary Guaranty. The execution, delivery
and performance of this Subsidiary Guaranty and the documents or instruments
required hereunder, and the use of the proceeds of the borrowings, and the
issuance of the Letters of Credit will not violate any provision of any existing
law or regulation binding on the Subsidiary Guarantors, or any order, judgment,
award or decree of any court, arbitrator or governmental authority binding on
the Subsidiary Guarantors, or the certificate of incorporation or bylaws of each
of the Subsidiary Guarantors or any securities issued by each of the Subsidiary
Guarantors, or any mortgage, indenture, lease, contract or other agreement,
instrument or undertaking to which the Subsidiary Guarantors are a party or by
which the Subsidiary Guarantors or any of their assets may be bound, the
violation of which would have a material adverse effect on the business,
operations, assets or financial condition of the Subsidiary Guarantors and will
not result in, or require, the creation or imposition of any Lien on any of
their property, assets or revenues pursuant to the provisions of any such
mortgage, indenture, lease, contract or other agreement, instrument or
undertaking.

                        SECTION 4. AFFIRMATIVE COVENANTS.

         So long as any Loan shall remain unpaid or any Bank shall have any
Commitment hereunder and until the expiration, the cancellation and the payment
in full or cash collateralization of all Letters of Credit, the Subsidiary
Guarantors covenant and agree, unless Requisite Banks shall otherwise consent in
writing:

franchises material to its business.

         4.2 Compliance with Laws, Etc. Subsidiary Guarantors shall perform and
promptly comply with the requirements of all applicable laws, rules, regulations
and orders other than those with which the failure to comply would not have a
Material Adverse Effect, such compliance to include, without limitation, paying
when due all taxes, assessments and governmental charges imposed upon it or upon
any of its properties or assets or in respect of any of its franchises,
businesses, income or property in accordance with Section 6.8 of the Credit
Agreement.

         4.3 Books and Records. Subsidiary Guarantors shall keep and maintain
books of record and account with respect to their operations in accordance with
generally accepted accounting principles and shall permit Administrative Agent
or any Bank and their respective officers, employees and authorized agents, to

administration of this Subsidiary Guaranty, to examine, copy and make excerpts
from the books and records of the Subsidiary Guarantors and their Subsidiaries
and to inspect the properties of the Subsidiary Guarantors and their
Subsidiaries, both real and personal, at such reasonable times as Administrative
