                              SUBSIDIARIES GUARANTY

                  GUARANTY, dated as of July 31, 1996 (as amended, modified or
supplemented from time to time, this "Guaranty"), made by each of the
undersigned (each a "Guarantor" and, together with any other entity that becomes
a party hereto pursuant to Section 26 hereof, the "Guarantors"). Except as
otherwise defined herein, terms used herein and defined in the Credit Agreement
(as defined below) shall be used herein as therein defined.

                              W I T N E S S E T H :

                  WHEREAS, Transworld Home HealthCare, Inc. ("Borrower"), the
lenders from time to time party thereto (the "Banks"), and Bankers Trust
Company, as Agent (together with any successor agent, the "Agent"), have entered
into a Credit Agreement, dated as of July 31, 1996 (as amended, modified or
supplemented from time to time, the "Credit Agreement"), providing for the
making of Loans to the Borrower and the issuance of, and participation in,
Letters of Credit for the account of the Borrower, all as contemplated therein
(the Banks, each Letter of Credit Issuer, the Agent and the Collateral Agent are
herein called the "Bank Creditors");

                  WHEREAS, the Borrower may from time to time be party to one or
more (i) interest rate agreements, interest rate cap agreements, interest rate
collar agreements or other similar agreements or arrangements, (ii) foreign
exchange contracts, currency swap agreements or similar agreements or
arrangements designed to protect against the fluctuations in currency values
and/or (iii) other types of hedging agreements from time to time (each such
agreement or arrangement with an Other Creditor (as hereinafter defined), an
"Interest Rate Protection Agreement or Other Hedging Agreement"), with a Bank or
an affiliate of a Bank (each such Bank or affiliate, even if the respective Bank
subsequently ceases to be a Bank under the Credit Agreement for any reason,
together with such Bank's or affiliate's successors and assigns, collectively,
the "Other Creditors," and together with the Bank Creditors, are herein called
the "Creditors");

                  WHEREAS, each Guarantor is a Subsidiary of the Borrower;

                  WHEREAS, it is a condition to the making of Loans under the
Credit Agreement that each Guarantor shall have executed and delivered this
Guaranty; and

                  WHEREAS, each Guarantor will obtain benefits from the
incurrence of Loans by the Borrower under the Credit Agreement and the entering
into of Interest Rate Protection Agreements or Other Hedging Agreements and,
accordingly, desires to execute this Guaranty 
<PAGE>   2
in order to satisfy the conditions described in the preceding paragraph and to
induce the Banks to make Loans to the Borrower and Other Creditors to enter into
Interest Rate Protection Agreements or Other Hedging Agreements with the
Borrower;

                  NOW, THEREFORE, in consideration of the foregoing and other
benefits accruing to each Guarantor, the receipt and sufficiency of which are
hereby acknowledged, each Guarantor hereby makes the following representations
and warranties to the Creditors and hereby covenants and agrees with each
Creditor as follows:

                  1. Each Guarantor, jointly and severally, irrevocably and
unconditionally guarantees: (i) to the Bank Creditors the full and prompt
payment when due (whether at the stated maturity, by acceleration or otherwise)
of (x) the principal of and interest on the Notes issued by, and the Loans made
to, the Borrower under the Credit Agreement and all reimbursement obligations
and Unpaid Drawings with respect to Letters of Credit and (y) all other
obligations (including obligations which, but for the automatic stay under
Section 362(a) of the Bankruptcy Code, would become due) and liabilities owing
by the Borrower to the Bank Creditors under the Credit Agreement (including,
without limitation, indemnities, Fees and interest thereon) and the other Credit
Documents to which the Borrower is a party, whether now existing or hereafter
incurred under, arising out of or in connection with the Credit Agreement or any
such other Credit Document and the due performance and compliance with the terms
of the Credit Documents by the Borrower (all such principal, interest,
liabilities and obligations under this clause (i), except to the extent
consisting of obligations or liabilities with respect to Interest Rate
Protection Agreements or Other Hedging Agreements, being herein collectively
called the "Credit Document Obligations"); and (ii) to each Other Creditor the
full and prompt payment when due (whether at the stated maturity, by
acceleration or otherwise) of all obligations (including obligations which, but
for the automatic stay under Section 362(a) of the Bankruptcy Code, would become
due) and liabilities owing by the Borrower under any Interest Rate Protection
Agreements or Other Hedging Agreements, whether now in existence or hereafter
arising, and the due performance and compliance by the Borrower with all terms,
conditions and agreements contained therein (all such obligations and
liabilities being herein collectively called the "Other Obligations", and
together with the Credit Document Obligations are herein collectively called the
"Guaranteed Obligations"). Each Guarantor understands, agrees and confirms that
the Creditors may enforce this Guaranty up to the full amount of the Guaranteed
Obligations against each Guarantor without proceeding against any other
Guarantor, the Borrower, against any security for the Guaranteed Obligations, or
under any other guaranty covering all or a portion of the Guaranteed
Obligations. All payments by each Guarantor under this Guaranty shall be made on
the same basis as payments by the Borrower under Sections 4.03 and 4.04 of the
Credit Agreement.

                  2. Additionally, each Guarantor, jointly and severally,
unconditionally and irrevocably, guarantees the payment of any and all
Guaranteed Obligations of the Borrower


                                       -2-
<PAGE>   3
to the Creditors whether or not due or payable by the Borrower upon the
occurrence in respect of the Borrower of any of the events specified in Section
10.05 of the Credit Agreement, and unconditionally and irrevocably, jointly and
severally, promises to pay such Guaranteed Obligations to the Creditors, or
order, on demand, in lawful money of the United States.

                  3. The liability of each Guarantor hereunder is exclusive and
independent of any security for or other guaranty of the Guaranteed Obligations
of the Borrower whether executed by such Guarantor, any other Guarantor, any
other guarantor or by any other party, and the liability of each Guarantor
hereunder shall not be affected or impaired by (a) any direction as to
application of payment by the Borrower or by any other party, (b) any other
continuing or other guaranty, undertaking or maximum liability of a guarantor or
of any other party as to the Guaranteed Obligations of the Borrower, (c) any
payment on or in reduction of any such other guaranty or undertaking, (d) any
dissolution, termination or increase, decrease or change in personnel by the
Borrower or (e) any payment made to any Creditor on the Guaranteed Obligations
which any Creditor repays the Borrower pursuant to court order in any
bankruptcy, reorganization, arrangement, moratorium or other debtor relief
proceeding, and each Guarantor waives any right to the deferral or modification
of its obligations hereunder by reason of any such proceeding. This is a
guaranty of payment and not of collection.

                  4. The obligations of each Guarantor hereunder are independent
of the obligations of any other Guarantor, any other guarantor or the Borrower,
and a separate action or actions may be brought and prosecuted against each
Guarantor whether or not action is brought against any other Guarantor, any
other guarantor or the Borrower and whether or not any other Guarantor, any
other guarantor of the Borrower or the Borrower be joined in any such action or
actions. Each Guarantor waives, to the fullest extent permitted by law, the
benefit of any statute of limitations affecting its liability hereunder or the
enforcement thereof. Any payment by the Borrower or other circumstance which
operates to toll any statute of limitations as to the Borrower shall operate to
toll the statute of limitations as to each Guarantor.

                  5. Each Guarantor hereby waives (to the fullest extent
permitted by applicable law) notice of acceptance of this Guaranty and notice of
any liability to which it may apply, and waives promptness, diligence,
presentment, demand of payment, protest, notice of dishonor or nonpayment of any
such liabilities, suit or taking of other action by the Agent or any other
Creditor against, and any other notice to, any party liable thereon (including
such Guarantor or any other guarantor or the Borrower).

                  6. Any Creditor may (except as shall be required by applicable
statute and cannot be waived) at any time and from time to time without the
consent of, or notice to, any Guarantor, without incurring responsibility to
such Guarantor, without impairing or releasing

                                       -3-
<PAGE>   4
the obligations of such Guarantor hereunder, upon or without any terms
or conditions and in whole or in part:

                  (a) change the manner, place or terms of payment of, and/or
         change or extend the time of payment of, renew, increase, accelerate or
         alter, any of the Guaranteed Obligations, any security therefor, or any
         liability incurred directly or indirectly in respect thereof, and the
         guaranty herein made shall apply to the Guaranteed Obligations as so
         changed, extended, renewed or altered;

                  (b) sell, exchange, release, surrender, realize upon or
         otherwise deal with in any manner and in any order any property by
         whomsoever at any time pledged or mortgaged to secure, or howsoever
         securing, the Guaranteed Obligations or any liabilities (including any
         of those hereunder) incurred directly or indirectly in respect thereof
         or hereof, and/or any offset thereagainst;

                  (c) exercise or refrain from exercising any rights against the
         Borrower or others or otherwise act or refrain from acting;

                  (d) settle or compromise any of the Guaranteed Obligations,
         any security therefor or any liability (including any of those
         hereunder) incurred directly or indirectly in respect thereof or
         hereof, and may subordinate the payment of all or any part thereof to
         the payment of any liability (whether due or not) of the Borrower to
         creditors of the Borrower;

                  (e) apply any sums by whomsoever paid or howsoever realized to
         any liability or liabilities of the Borrower to the Creditors
         regardless of what liabilities of the Borrower remain unpaid;

                  (f) consent to or waive any breach of, or any act, omission or
         default under, any of the Interest Rate Protection Agreements or Other
         Hedging Agreements, the Credit Documents or any of the instruments or
         agreements referred to therein, or otherwise amend, modify or
         supplement any of the Interest Rate Protection Agreements or Other
         Hedging Agreements, the Credit Documents or any of such other
         instruments or agreements; and/or

                  (g) act or fail to act in any manner referred to in this
         Guaranty which may deprive such Guarantor of its right to subrogation
         against the Borrower to recover full indemnity for any payments made
         pursuant to this Guaranty.

                  7. No invalidity, irregularity or unenforceability of all or
any part of the Guaranteed Obligations or of any security therefor shall affect,
impair or be a defense to this Guaranty, and this Guaranty shall be primary,
absolute and unconditional notwithstanding the occurrence of any event or the
existence of any other circumstances which might

                                                 
                                      -4-
<PAGE>   5
constitute a legal or equitable discharge of a surety or guarantor except
payment in full of the Guaranteed Obligations.

                  8. This Guaranty is a continuing one and all liabilities to
which it applies or may apply under the terms hereof shall be conclusively
presumed to have been created in reliance hereon. No failure or delay on the
part of any Creditor in exercising any right, power or privilege hereunder shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right, power or privilege hereunder preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. The rights and
remedies herein expressly specified are cumulative and not exclusive of any
rights or remedies which any Creditor would otherwise have. No notice to or
demand on any Guarantor in any case shall entitle such Guarantor to any other
further notice or demand in similar or other circumstances or constitute a
waiver of the rights of any Creditor to any other or further action in any
circumstances without notice or demand. It is not necessary for any Creditor to
inquire into the capacity or powers of the Borrower or any of its Subsidiaries
or the officers, directors, partners or agents acting or purporting to act on
its behalf, and any indebtedness made or created in reliance upon the professed
exercise of such powers shall be guaranteed hereunder.

                  9. Any indebtedness of the Borrower now or hereafter held by
any Guarantor is hereby subordinated to the indebtedness of the Borrower to the
Creditors; and such indebtedness of the Borrower to any Guarantor, if the Agent,
after an Event of Default has occurred and is continuing, so requests, shall be
collected, enforced and received by such Guarantor as trustee for the Creditors
and be paid over to the Creditors on account of the indebtedness of the Borrower
to the Creditors, but without affecting or impairing in any manner the liability
of such Guarantor under the other provisions of this Guaranty. Prior to the
transfer by any Guarantor of any note or negotiable instrument evidencing any
indebtedness of the Borrower to such Guarantor, such Guarantor shall mark such
note or negotiable instrument with a legend that the same is subject to this
subordination. Without limiting the generality of the foregoing, each Guarantor
hereby agrees with the Creditors that it will not exercise any right of
subrogation which it may at any time otherwise have as a result of this Guaranty
(whether contractual, under Section 509 of the Bankruptcy Code or otherwise)
until all Guaranteed Obligations have been irrevocably paid in full in cash.

             10. (a) Each Guarantor waives any right (except as shall be
required by applicable statute or law and cannot be waived) to require the
Creditors to: (i) proceed against the Borrower, any other Guarantor, any other
guarantor of the Borrower or any other party; (ii) proceed against or exhaust
any security held from the Borrower, any other Guarantor, any other guarantor of
the Borrower or any other party; or (iii) pursue any other remedy in the
Creditors' power whatsoever. Each Guarantor waives any (to the fullest extent
permitted by applicable law) defense based on or arising out of any defense of
the Borrower, any other Guarantor, any other 
                   

                                       -5-
<PAGE>   6
guarantor of the Borrower or any other party other than payment in full of the
Guaranteed Obligations, including, without limitation, any defense based on or
arising out of the disability of the Borrower, any other Guarantor, any other
guarantor of the Borrower or any other party, or the unenforceability of the
Guaranteed Obligations or any part thereof from any cause, or the cessation from
any cause of the liability of the Borrower other than payment in full of the
Guaranteed Obligations. The Creditors may, at their election, foreclose on any
security held by the Agent, the Collateral Agent or the other Creditors by one
or more judicial or nonjudicial sales, whether or not every aspect of any such
sale is commercially reasonable (to the extent such sale is permitted by
applicable law), or exercise any other right or remedy the Creditors may have
against the Borrower or any other party, or any security, without affecting or
impairing in any way the liability of any Guarantor hereunder except to the
extent the Guaranteed Obligations have been paid in full. Each Guarantor waives
any defense arising out of any such election by the Creditors, even though such
election operates to impair or extinguish any right of reimbursement or
subrogation or other right or remedy of such Guarantor against the Borrower or
any other party or any security.

                  (b) Each Guarantor waives all presentments, demands for
performance, protests and notices, including, without limitation, notices of
nonperformance, notices of protest, notices of dishonor, notices of acceptance
of this Guaranty, and notices of the existence, creation or incurring of new or
additional indebtedness. Each Guarantor assumes all responsibility for being and
keeping itself informed of the Borrower's financial condition and assets, and of
all other circumstances bearing upon the risk of nonpayment of the Guaranteed
Obligations and the nature, scope and extent of the risks which such Guarantor
assumes and incurs hereunder, and agrees that the Creditors shall have no duty
to advise any Guarantor of information known to them regarding such
circumstances or risks.

                  (c) Each Guarantor understands, is aware and hereby
acknowledges that to the extent the Guaranteed Obligations are secured by real
property located in the State of California, such Guarantor shall be liable for
the full amount of its liability hereunder notwithstanding foreclosure on such
real property by trustee sale or any other reason impairing such Guarantor's or
any Creditor's right to proceed against any Credit Party. Each Guarantor hereby
waives, to the fullest extent permitted by law, all rights and benefits under
Section 2809 of the California Civil Code purporting to reduce a guarantor's
obligation in proportion to the principal obligation. Each Guarantor hereby
waives all rights and benefits under Section 580a of the California Code of
Civil Procedure purporting to limit the amount of any deficiency judgment which
might be recoverable following the occurrence of a trustee's sale under a deed
of trust and all rights and benefits under Section 580b of the California Code
of Civil Procedure stating that no deficiency may be recovered on a real
property purchase money obligation. Each Guarantor further understands, is aware
and hereby acknowledges that if the Creditors elect to nonjudicially foreclose
on any real property security located in the State of California any right of
subrogation of such Guarantor against the Creditors may be impaired or
extinguished and that as a result of such impairment or extinguishment of
subrogation rights, such Guarantor may have a defense to a deficiency judgment
arising out of the operation of (i) Section 580d of the California Code of Civil
Procedure which states that no deficiency may be recovered on a note secured by
a deed of
                                              
                                       -6-
<PAGE>   7
trust on real property in case such real property is sold under the power of
sale contained in such deed of trust, and (ii) related principles of estoppel.
To the fullest extent permitted by law, each Guarantor waives all rights and
benefits and any defense arising out of the operation of Section 580d of the
California Code of Civil Procedure and related principles of estoppel, even
though such election operates to impair or extinguish any right of reimbursement
or subrogation or other right or remedy of such Guarantor against any Credit
Party or any other party or any security. In addition, each Guarantor hereby
waives, to the fullest extent permitted by applicable law, without limiting the
generality of the foregoing or any other provision hereof, all rights and
benefits which might otherwise be available to such Guarantor under Section 726
of the California Code of Civil Procedure and all rights and benefits which
might otherwise be available to such Guarantor under California Civil Code
Sections 2809, 2810, 2815, 2819, 2821, 2839, 2845, 2848, 2849, 2850, 2899 and
3433.

                  (d) Each Guarantor hereby further waives (to the fullest
extent permitted by applicable law): (1) all rights and defenses arising out of
an election of remedies by the Creditors, even though that election of remedies,
such as a nonjudicial foreclosure with respect to security for a Guaranteed
Obligation, has destroyed such Guarantor's rights of subrogation and
reimbursement against the principal by the operation of Section 580d of the
California Code of Civil Procedure or otherwise; (2) such Guarantor's rights of
subrogation and reimbursement and any other rights and defenses available to
such Guarantor by reason of the California Civil Code Sections 2787 to 2855,
inclusive, including, without limitation, (i) any defenses such Guarantor may
have to the Guaranteed Obligations by reason of an election of remedies by the
Creditors and (ii) any rights or defenses such Guarantor may have by reason of
protection afforded to the principal borrower with respect to the obligation so
guaranteed pursuant to the antideficiency or other laws of the State of
California limiting or discharging the borrower's indebtedness, including,
without limitation, California Code of Civil Procedure Sections 580a, 580b, 580d
or 726.

11. Notwithstanding anything else to the contrary in this Guaranty, the
Creditors agree that this Guaranty may be enforced only by the action of the
Agent or the Collateral Agent, in each case acting upon the instructions of the
Required Banks (or, after the date on which all Credit Document Obligations have
been paid in full, the holders of at least a majority of the outstanding Other
Obligations) and that no other Creditor shall have any right individually to
seek to enforce or to enforce this Guaranty or to realize upon the security to
be granted by the Security Documents, it being understood and agreed that such
rights and remedies may be exercised by the Agent or the Collateral Agent or the
holders of at least a majority of the outstanding Other Obligations, as the case
may be, for the benefit of the Creditors upon the terms of this Guaranty and the
Security Documents. The Creditors further agree that this Guaranty may not be
enforced against any director, officer, employee, or stockholder of any
Guarantor (except to the extent such stockholder is also a Guarantor hereunder).
It is understood that the agreement in this paragraph 11 is among and solely for


                                      -7-
<PAGE>   8
the benefit of the Banks and that if the Required Banks so agree (without
requiring the consent of any Guarantor), the Guaranty may be directly enforced
by any Creditor.

             12. In order to induce the Banks to make Loans and issue Letters of
Credit pursuant to the Credit Agreement, and in order to induce the Other
Creditors to execute, deliver and perform the Interest Rate Protection
Agreements or Other Hedging Agreements, each Guarantor represents, warrants and
covenants that:

                  (a) Such Guarantor (i) is a duly organized and validly
         existing corporation and is in good standing under the laws of the
         jurisdiction of its organization, and has the corporate power and
         authority to own its property and assets and to transact the business
         in which it is engaged and presently proposes to engage and (ii) is
         duly qualified and is authorized to do business and is in good standing
         in all jurisdictions where it is required to be so qualified and where
         the failure to be so qualified could reasonably be expected to have a
         Material Adverse Effect.

                  (b) Such Guarantor has the corporate power and authority to
         execute, deliver and carry out the terms and provisions of this
         Guaranty and each other Credit Document to which it is a party and has
         taken all necessary corporate action to authorize the execution,
         delivery and performance by it of each such Credit Document. Such
         Guarantor has duly executed and delivered this Guaranty and each other
         Credit Document to which it is a party and each such Credit Document
         constitutes the legal, valid and binding obligation of such Guarantor
         enforceable in accordance with its terms, except to the extent that the
         enforceability hereof or thereof may be limited by applicable
         bankruptcy, insolvency, reorganization, moratorium or other similar
         laws affecting creditors' rights generally and by equitable principles
         (regardless of whether enforcement is sought in equity or at law).

                  (c) Neither the execution, delivery or performance by such
         Guarantor of this Guaranty or any other Credit Document to which it is
         a party, nor compliance by it with the terms and provisions hereof or
         thereof (i) will contravene any applicable provision of any law,
         statute, rule or regulation, or any order, writ, injunction or decree
         of any court or governmental instrumentality, (ii) will conflict or be
         inconsistent with or result in any breach of, any of the terms,
         covenants, conditions or provisions of, or constitute a default under,
         or (other than pursuant to the Security Documents) result in the
         creation or imposition of (or the obligation to create or impose) any
         Lien upon any of the property or assets of such Guarantor or any of its
         Subsidiaries pursuant to the terms of any indenture, mortgage, deed of
         trust, loan agreement, credit agreement or other material agreement or
         other instrument to which such Guarantor or any of its Subsidiaries is
         a party or by which it or any of its property or assets is bound or to
         which it may be subject or (iii) will violate any provision of the
         certificate of incorporation or by-laws of such Guarantor or any of its
         Subsidiaries.

                                       -8-
<PAGE>   9
        
                  (d) No order, consent, approval, license, authorization or
         validation of, or filing, recording or registration with, or exemption
         by, any governmental or public body or authority, or any subdivision
         thereof, is required to authorize, or is required in connection with,
         (i) the execution, delivery and performance of this Guaranty or any
         other Credit Document to which such Guarantor is a party, or (ii) the
         legality, validity, binding effect or enforceability of this Guaranty
         or any other Credit Document to which such Guarantor is a party other
         than filings, registrations or recordings required to perfect the
         security interests granted to the Collateral Agent pursuant to the
         Security Agreement all of which have been made or will be made within
         the time required therefor by the Security Agreement.

                  (e) There are no actions, suits or proceedings pending or to
         the knowledge of such Guarantor, threatened (i) with respect to such
         Guarantor that are likely to have a Material Adverse Effect or (ii)
         that could reasonably be expected to have a material adverse effect on
         the rights or remedies of the Creditors or on the ability of such
         Guarantor to perform its respective obligations to the Creditors
         hereunder and under the other Credit Documents to which it is a party.

             13. Each Guarantor covenants and agrees that on and after the date
hereof and until the termination of the Total Revolving Loan Commitment and all
Interest Rate Protection Agreements or Other Hedging Agreements and when no Note
or Letter of Credit remains outstanding (other than Letters of Credit, together
with all Fees that have accrued and will accrue thereon through the stated
termination date of such Letters of Credit, which have been supported in a
manner satisfactory to the Letter of Credit Issuer in its sole and absolute
discretion) and all Guaranteed Obligations have been paid in full (other than
indemnities described in Section 13.13 of the Credit Agreement and analogous
provisions in the Security Documents which are not then due and payable), such
Guarantor shall take, or will refrain from taking, as the case may be, all
actions that are necessary to be taken or not taken so that no violation of any
provision, covenant or agreement contained in Section 8 or 9 of the Credit
Agreement, and so that no Default or Event of Default, is caused by the actions
of such Guarantor or any of its Subsidiaries.

             14. The Guarantors hereby jointly and severally agree to pay all
reasonable out-of-pocket costs and expenses of each Creditor in connection with
the enforcement of this Guaranty and any amendment, waiver or consent relating
hereto (including, without limitation, the reasonable fees and disbursements of
counsel (including in-house counsel) employed by any of the Creditors).

             15. This Guaranty shall be binding upon each Guarantor and its
successors and assigns and shall inure to the benefit of the Creditors and their
successors and assigns.

             16. Neither this Guaranty nor any provision hereof may be changed,
waived, discharged or terminated except with the written consent of each
Guarantor directly affected                                               

                                      -9-

thereby and either (x) the Required Banks (or to the extent required by Section
13.12 of the Credit Agreement, with the written consent of each Bank) at all
times prior to the time on which all Credit Document Obligations have been paid
in full or (y) the holders of at least a majority of the outstanding Other
Obligations at all times after the time on which all Credit Document Obligations
have been paid in full; provided, that any change, waiver, modification or
variance affecting the rights and benefits of a single Class (as defined below)
of Creditors (and not all Creditors in a like or similar manner) shall require
the written consent of the Requisite Creditors (as defined below) of such Class
of Creditors (it being understood that the addition or release of any Guarantor
hereunder shall not constitute a change, waiver, discharge or termination
affecting any Guarantor other than the Guarantor so added or released). For the
purpose of this Guaranty the term "Class" shall mean each class of Creditors,
i.e., whether (x) the Bank Creditors as holders of the Credit Document
Obligations or (y) the Other Creditors as the holders of the Other Obligations.
For the purpose of this Guaranty, the term "Requisite Creditors" of any Class
shall mean each of (x) with respect to the Credit Document Obligations, the
Required Banks and (y) with respect to the Other Obligations, the holders of at
least a majority of all obligations outstanding from time to time under the
Interest Rate Protection Agreements or Other Hedging Agreements.

             17. Each Guarantor acknowledges that an executed (or conformed)
copy of each of the Credit Documents and Interest Rate Protection Agreements or
Other Hedging Agreements existing as of the date hereof has been made available
to its principal executive officers and such officers are familiar with the
contents thereof and that an executed (or conformed) copy of any Credit Document
or Interest Rate Protection Agreement or Other Hedging Agreement created after
the date hereof will be made available to its principal executive officers and
such officers will be familiar with the contents thereof.

                  18. In addition to any rights now or hereafter granted under
applicable law (including, without limitation, Section 151 of the New York
Debtor and Creditor Law) and not by way of limitation of any such rights, upon
the occurrence and during the continuance of an Event of Default (such term to
mean and include any "Event of Default" as defined in the Credit Agreement or
any payment default under any Interest Rate Protection Agreement or Other
Hedging Agreement continuing after any applicable grace period), each Creditor
is hereby authorized at any time or from time to time, without notice to any
Guarantor or to any other Person, any such notice being expressly waived, to set
off and to appropriate and apply any and all deposits (general or special) and
any other indebtedness at any time held or owing by such Creditor to or for the
credit or the account of such Guarantor, against and on account of the
obligations and liabilities of such Guarantor to such Creditor under this
Guaranty, irrespective of whether or not such Creditor shall have made any
demand hereunder and although said obligations, liabilities, deposits or claims,
or any of them, shall be contingent or unmatured. Notwithstanding anything to
the contrary contained in this Section 18, no Creditor shall exercise any such
right of set-off without the prior consent of the Agent or the Required Banks so
long as the Guaranteed Obligations shall be secured by any Real Property located
in the State of California, it being understood and agreed, however, that this


                                      -10-

<PAGE>   11
sentence is for the sole benefit of the Creditors and may be amended, modified
or waived in any respect by the Required Banks without the requirement of prior
notice to or consent by any Credit Party and does not constitute a waiver of any
rights against any Credit Party or against any Collateral.

             19. All notices, requests, demands or other communications pursuant
hereto shall be deemed to have been duly given or made when delivered by hand or
overnight courier or by certified mail, return receipt requested, to the Person
to which such notice, request, demand or other communication is required or
permitted to be given or made under this Guaranty, addressed to such party at
(i) in the case of any Bank Creditor, as provided in the Credit Agreement, (ii)
in the case of any Guarantor, at its address set forth opposite its signature
below and (iii) in the case of any Other Creditor, at such address as such Other
Creditor shall have specified in writing to the Guarantor; or in any case at
such other address as any of the Persons listed above may hereafter notify the
others in writing.

             20. If claim is ever made upon any Creditor for repayment or
recovery of any amount or amounts received in payment or on account of any of
the Guaranteed Obligations and any of the aforesaid payees repays all or part of
said amount by reason of (i) any judgment, decree or order of any court or
administrative body having jurisdiction over such payee or any of its property
or (ii) any settlement or compromise of any such claim effected by such payee
with any such claimant (including the Borrower), then and in such event each
Guarantor agrees that any such judgment, decree, order, settlement or compromise
shall be binding upon such Guarantor, notwithstanding any revocation hereof or
other instrument evidencing any liability of the Borrower, and such Guarantor
shall be and remain liable to the aforesaid payees hereunder for the amount so
repaid or recovered to the same extent as if such amount had never originally
been received by any such payee.

                  21. (a) THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS OF THE
CREDITORS AND OF THE UNDERSIGNED HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK. Any legal action or proceeding
with respect to this Guaranty or any other Credit Document to which such
Guarantor is a party may be brought in the courts of the State of New York or of
the United States of America for the Southern District of New York, and, by
execution and delivery of this Guaranty, each Guarantor hereby irrevocably
accepts for itself and in respect of its property, generally and
unconditionally, the jurisdiction of the aforesaid courts. Each Guarantor hereby
further irrevocably waives any claim that any such courts lack jurisdiction over
such Guarantor, and agrees not to plead or claim, in any legal action or
proceeding with respect to this Guaranty or any other Credit Document to which
such Guarantor is a party brought in any of the aforesaid courts, that any such
court lacks jurisdiction over such Guarantor. Each Guarantor further irrevocably
consents to the service of process out of any of the aforementioned courts in
any such action or proceeding by the mailing of copies thereof by registered or
certified mail, postage prepaid, to each Guarantor at its address set forth
opposite its signature below, such service to become

                                      -11-
<PAGE>   12
effective 30 days after such mailing. Each Guarantor hereby irrevocably waives
any objection to such service of process and further irrevocably waives and
agrees not to plead or claim in any action or proceeding commenced hereunder or
under any other Credit Document to which such Guarantor is a party that service
of process was in any way invalid or ineffective. Nothing herein shall affect
the right of any of the Creditors to serve process in any other manner permitted
by law or to commence legal proceedings or otherwise proceed against each
Guarantor in any other jurisdiction.

                  (b) Each Guarantor hereby irrevocably waives any objection
which it may now or hereafter have to the laying of venue of any of the
aforesaid actions or proceedings arising out of or in connection with this
Guaranty or any other credit document brought in the courts referred to in
clause (a) above and hereby further irrevocably waives and agrees not to plead
or claim in any such court that such action or proceeding brought in any such
court has been brought in an inconvenient forum.

             22. In the event that all of the capital stock of one or more
Guarantors is sold or otherwise disposed of (but excluding for all purposes of
this Section 22 transfers of such capital stock to the Borrower or another
Subsidiary thereof) or liquidated in compliance with the requirements of Section
9.02 of the Credit Agreement (or such sale or other disposition or liquidation
has been approved in writing by the Required Banks (or all Banks if required by
Section 13.12 of the Credit Agreement)) and the proceeds of such sale,
disposition or liquidation are applied in accordance with the provisions of the
Credit Agreement, to the extent applicable, such Guarantor shall be released
from this Guaranty and this Guaranty shall, as to each such Guarantor or
Guarantors, terminate, and have no further force or effect (it being understood
and agreed that the sale of one or more Persons (but excluding for all purposes
of this Section 22 transfers of such capital stock to the Borrower or another
Subsidiary thereof) that own, directly or indirectly, all of the capital stock
or partnership interests of any Guarantor shall be deemed to be a sale of such
Guarantor for the purposes of this Section 22).

             23. This Guaranty may be executed in any number of counterparts and
by the different parties hereto on separate counterparts, each of which when so
executed and delivered shall be an original, but all of which shall together
constitute one and the same instrument. A set of counterparts executed by all
the parties hereto shall be lodged with the Borrower and the Agent.

             24. EACH GUARANTOR AND EACH OF THE CREDITORS HEREBY IRREVOCABLY
WAIVES ALL RIGHTS TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM
ARISING OUT OF OR RELATING TO THIS GUARANTY, THE OTHER CREDIT DOCUMENTS OR THE
TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

                                           
                                      -12-
<PAGE>   13
             25. All payments made by any Guarantor hereunder will be made
without setoff, counterclaim or other defense.

             26. It is understood and agreed that any Subsidiary of the Borrower
that is required to execute a counterpart of this Guaranty after the date hereof
pursuant to the requirements of the Credit Agreement shall automatically become
a Guarantor hereunder by executing a counterpart hereof and delivering the same
to the Agent.

             27. At any time a payment in respect of the Guaranteed Obligations
is made under this Guaranty, the right of contribution of each Guarantor against
each other Guarantor shall be determined as provided in the immediately
following sentence, with the right of contribution of each Guarantor to be
revised and restated as of each date on which a payment (a "Relevant Payment")
is made on the Guaranteed Obligations under this Guaranty. At any time that a
Relevant Payment is made by a Guarantor that results in the aggregate payments
made by such Guarantor in respect of the Guaranteed Obligations to and including
the date of the Relevant Payment exceeding such Guarantor's Contribution
Percentage (as defined below) of the aggregate payments made by all Guarantors
in respect of the Guaranteed Obligations to and including the date of the
Relevant Payment (such excess, the "Aggregate Excess Amount"), each such
Guarantor shall have a right of contribution against each other Guarantor who
has made payments in respect of the Guaranteed Obligations to and including the
date of the Relevant Payment in an aggregate amount less than such other
Guarantor's Contribution Percentage of the aggregate payments made to and
including the date of the Relevant Payment by all Guarantors in respect of the
Guaranteed Obligations (the aggregate amount of such deficit, the "Aggregate
Deficit Amount") in an amount equal to (x) a fraction the numerator of which is
the Aggregate Excess Amount of such Guarantor and the denominator of which is
the Aggregate Excess Amount of all Guarantors multiplied by (y) the Aggregate
Deficit Amount of such other Guarantor. A Guarantor's right of contribution
pursuant to the preceding sentences shall arise at the time of each computation,
subject to adjustment to the time of any subsequent computation; provided, that
no Guarantor may take any action to enforce such right until the Guaranteed
Obligations have been paid in full and the Total Commitment has been terminated,
it being expressly recognized and agreed by all parties hereto that any
Guarantor's right of contribution arising pursuant to this Contribution
Agreement against any other Guarantor shall be expressly junior and subordinate
to such other Guarantor's obligations and liabilities in respect of the
Guaranteed Obligations and any other obligations owing under this Guaranty. As
used in this Section 27: (i) each Guarantor's "Contribution Percentage" shall
mean the percentage obtained by dividing (x) the Adjusted Net Worth (as defined
below) of such Guarantor by (y) the aggregate Adjusted Net Worth of all
Guarantors; (ii) the "Adjusted Net Worth" of each Guarantor shall mean the
greater of (x) the Net Worth (as defined below) of such Guarantor and (y) zero;
and (iii) the "Net Worth" of each Guarantor shall mean the amount by which the
fair salable value of such Guarantor's assets on the date of any Relevant
Payment exceeds its existing debts and other liabilities (including contingent
liabilities, but without giving effect to any Guaranteed Obligations arising
under this Guaranty) on such date. All parties hereto recognize and agree
                                                

                                      -13-
<PAGE>   14
that, except for any right of contribution arising pursuant to this Section 27,
each Guarantor who makes any payment in respect of the Guaranteed Obligations
shall have no right of contribution or subrogation against any other Guarantor
in respect of such payment. Each of the Guarantors recognizes and acknowledges
that the rights to contribution arising hereunder shall constitute an asset in
favor of the party entitled to such contribution. In this connection, each
Guarantor has the right to waive its contribution right against any Guarantor to
the extent that after giving effect to such waiver such Guarantor would remain
solvent, in the determination of the Required Banks.

             28. Each Guarantor hereby confirms that it is its intention that
this Guaranty not constitute a fraudulent transfer or conveyance for purposes of
any bankruptcy, insolvency or similar law, the Uniform Fraudulent Conveyance Act
or any similar Federal, state of foreign law. To effectuate the foregoing
intention, each Guarantor hereby irrevocably agrees that the Guaranteed
Obligations shall be limited to the maximum amount as will, after giving effect
to such maximum amount and all other (contingent or otherwise) liabilities of
such Guarantor that are relevant under such laws, result in the Guaranteed
Obligations of such Guarantor in respect of such maximum amount not constituting
a fraudulent transfer or conveyance.

                  IN WITNESS WHEREOF, each Guarantor has caused this Guaranty to
be executed and delivered as of the date first above written.
