                    by Guarantor, Guarantied Party, the several members of the
                    Lender Group, and their respective counsel, and shall be

<PAGE>

                    accomplish the purposes and intentions of Guarantied
                    Party and Guarantor.

          (v)  Guarantied Obligations.  Guarantor hereby irrevocably and
               ----------------------
unconditionally guaranties to Guarantied Party for the benefit of the Lender
Group, as and for its own debt, until final and indefeasible payment thereof has
been made, (a) the payment of the Guarantied Obligations, in each case when and
as the same shall become due and payable, whether at maturity, pursuant to a
mandatory prepayment requirement, by acceleration, or otherwise; it being the
intent of Guarantor that the guaranty set forth herein shall be a guaranty of
payment and not a guaranty of collection; and (b) the punctual and faithful
performance, keeping, observance, and fulfillment by Debtor of all of the
agreements, conditions, covenants, and obligations of Debtor contained in the
Credit Agreement, and under each of the other Loan Documents.

          (w)  Continuing Guaranty.  This Guaranty includes Guarantied
               -------------------
Obligations arising under successive transactions continuing, compromising,
extending, increasing, modifying, releasing, or renewing the Guarantied
Obligations, changing the interest rate, payment terms, or other terms and
conditions thereof, or creating new or additional Guarantied Obligations after
prior Guarantied Obligations have been satisfied in whole or in part. To the
maximum extent permitted by law, Guarantor hereby waives any right to revoke
this Guaranty as to future Indebtedness. If such a revocation is effective
notwithstanding the foregoing waiver, Guarantor acknowledges and agrees that (a)
no such revocation shall be effective until written notice thereof has been
received by Guarantied Party, (b) no such revocation shall apply to any
Guarantied Obligations in existence on such date (including any subsequent
continuation, extension, or renewal thereof, or change in the interest rate,
payment terms, or other terms and conditions thereof), (c) no such revocation
shall apply to any Guarantied Obligations made or created after such date to the
extent made or created pursuant to a legally binding commitment of Guarantied
Party in existence on the date of such revocation, (d) no payment by Guarantor,
Debtor, or from any other source, prior to the date of such revocation shall
reduce the maximum obligation of Guarantor hereunder, and (e) any payment by
Debtor or from any source other than Guarantor subsequent to the date of such
revocation shall first be applied to that portion of the Guarantied Obligations
as to which the revocation is effective and which are not, therefore, guarantied
hereunder, and to the extent so applied shall not reduce the maximum obligation
of Guarantor hereunder.

          (x)  Performance Under this Guaranty.  In the event that Debtor fails
               -------------------------------
to make any payment of any Guarantied Obligations, on or before the due date
thereof, or if Debtor shall fail to perform, keep, observe, or fulfill any other
obligation referred to in clause (b) of Section 2 hereof in the manner provided
                          -----------------------
in the Credit Agreement or the other Loan Documents, as applicable, Guarantor
immediately shall cause such payment to be made or each of such obligations to
be performed, kept, observed, or fulfilled.

          (y)  Primary Obligations.  This Guaranty is a primary and original
               -------------------
obligation of Guarantor, is not merely the creation of a surety relationship,
and is an absolute, unconditional, and continuing guaranty of payment and
performance which shall remain in full force and effect without respect to
future changes in conditions. Guarantor agrees that it is directly, jointly and

                                       3.
<PAGE>

severally with any other guarantor of the Guarantied Obligations, liable to
Guarantied Party for the benefit of the Lender Group, that the obligations of
Guarantor hereunder are independent of the obligations of Debtor or any other
guarantor, and that a separate action may be brought against Guarantor, whether
such action is brought against Debtor or any other guarantor or whether Debtor
or any other guarantor is joined in such action. Guarantor agrees that its
liability hereunder shall be immediate and shall not be contingent upon the
exercise or enforcement by Guarantied Party for the benefit of the Lender Group
of whatever remedies it may have against Debtor or any other guarantor, or the
enforcement of any lien or realization upon any security Guarantied Party may at
any time possess. Guarantor agrees that any release which may be given by the
Lender Group or Guarantied Party on behalf thereof to Debtor or any other
guarantor shall not release Guarantor. Guarantor consents and agrees that the
Lender Group or Guarantied Party on behalf thereof shall be under no obligation
to marshal any property or assets of Debtor or any other guarantor in favor of
Guarantor, or against or in payment of any or all of the Guarantied Obligations.

          (z)  Waivers.
               -------

                    l.   To the fullest extent permitted by applicable law,
                         Guarantor hereby waives: (i) notice of acceptance
                         hereof; (ii) notice of any loans or other financial
                         accommodations made or extended under the Credit
                         Agreement, or the creation or existence of any
                         Guarantied Obligations; (iii) notice of the amount of
                         the Guarantied Obligations, subject, however, to
                         Guarantor's right to make inquiry of Guarantied Party
                         to ascertain the amount of the Guarantied Obligations
                         at any reasonable time; (iv) notice of any adverse
                         change in the financial condition of Debtor or of any
                         other fact that might increase Guarantor's risk
                         hereunder; (v) notice of presentment for payment,
                         demand, protest, and notice thereof as to any
                         instrument among the Loan Documents; (vi) notice of any
                         unmatured Event of Default or Event of Default under
                         the Credit Agreement; and (vii) all other notices
                         (except if such notice is specifically required to be
                         given to Guarantor under this Guaranty or any other
                         Loan Documents to which Guarantor is a party) and
                         demands to which Guarantor might otherwise be entitled.

                    m.   To the fullest extent permitted by applicable law,
                         Guarantor waives the right by statute or otherwise to
                         require the Lender Group or Guarantied Party on behalf
                         thereof to institute suit against Debtor or to exhaust
                         any rights and remedies which the Lender Group or
                         Guarantied Party on behalf thereof has or may have
                         against Debtor. In this regard, Guarantor agrees that
                         it is bound to the payment of each and all Guarantied
                         Obligations, whether now existing or hereafter arising,
                         as fully as if such Guarantied Obligations were
                         directly owing to the Lender Group or Guarantied Party
                         on behalf thereof by Guarantor. Guarantor further
                         waives any defense arising by reason of any disability
                         or other

                                       4.
<PAGE>

                         defense (other than the defense that the Guarantied
                         Obligations shall have been fully and finally performed
                         and indefeasibly paid) of Debtor or by reason of the
                         cessation from any cause whatsoever of the liability of
                         Debtor in respect thereof.

                    n.   To the fullest extent permitted by applicable law,
                         Guarantor hereby waives: (i) any rights to assert
                         against the Lender Group or Guarantied Party on behalf
                         thereof any defense (legal or equitable), set-off,
                         counterclaim, or claim which Guarantor may now or at
                         any time hereafter have against Debtor or any other
                         party liable to the Lender Group or Guarantied Party on
                         behalf thereof; (ii) any defense, set-off,
                         counterclaim, or claim, of any kind or nature, arising
                         directly or indirectly from the present or future lack
                         of perfection, sufficiency, validity, or enforceability
                         of the Guarantied Obligations or any security therefor;
                         (iii) any defense arising by reason of any claim or
                         defense based upon an election of remedies by the
                         Lender Group or Guarantied Party on behalf thereof
                         including any defense based upon an election of
                         remedies by the Lender Group or Guarantied Party on
                         behalf thereof under the provisions of (S)(S) 580d and
                         726 of the California Code of Civil Procedure, or any
                         similar law of California or any other jurisdiction;
                         (iv) the benefit of any statute of limitations
                         affecting Guarantor's liability hereunder or the
                         enforcement thereof, and any act which shall defer or
                         delay the operation of any statute of limitations
                         applicable to the Guarantied Obligations shall
                         similarly operate to defer or delay the operation of
                         such statute of limitations applicable to Guarantor's
                         liability hereunder.

                    o.   Until such time as all of the Guarantied Obligations
                         have been fully, finally, and indefeasibly paid in full
                         in cash: (i) Guarantor hereby waives and postpones any
                         right of subrogation Guarantor has or may have as
                         against Debtor with respect to the Guarantied
                         Obligations; (ii) in addition, Guarantor hereby waives
                         and postpones any right to proceed against Debtor or
                         any other Person, now or hereafter, for contribution,
                         indemnity, reimbursement, or any other suretyship
                         rights and claims (irrespective of whether direct or
                         indirect, liquidated or contingent), with respect to
                         the Guarantied Obligations; and (iii) in addition,
                         Guarantor also hereby waives and postpones any right to
                         proceed or to seek recourse against or with respect to
                         any property or asset of Debtor.

                    p.   If any of the Guarantied Obligations at any time are
                         secured by a mortgage or deed of trust upon real
                         property, Guarantied Party on behalf of the Lender
                         Group may elect, in its sole discretion, upon a default
                         with respect to the Guarantied Obligations, to
                         foreclose such mortgage or deed of trust judicially or
                         nonjudicially in any

                                       5.
<PAGE>

                         manner permitted by law, before or after enforcing this
                         Guaranty, without diminishing or affecting the
                         liability of Guarantor hereunder. Guarantor understands
                         that (a) by virtue of the operation of California's
                         antideficiency law applicable to nonjudicial
                         foreclosures, an election by the Lender Group or
                         Guarantied Party on behalf thereof nonjudicially to
                         foreclose such a mortgage or deed of trust probably
                         would have the effect of impairing or destroying rights
                         of subrogation, reimbursement, contribution, or
                         indemnity of Guarantor against Debtor or other
                         guarantors or sureties, and (b) absent the waiver given
                         by Guarantor herein, such an election would estop the
                         Lender Group or Guarantied Party on behalf thereof from
                         enforcing this Guaranty against Guarantor.
                         Understanding the foregoing, and understanding that
                         Guarantor is hereby relinquishing a defense to the
                         enforceability of this Guaranty, Guarantor hereby
                         waives any right to assert against the Lender Group or
                         Guarantied Party any defense to the enforcement of this
                         Guaranty, whether denominated "estoppel" or otherwise,
                         based on or arising from an election by the Lender
                         Group or Guarantied Party on behalf thereof
                         nonjudicially to foreclose any such mortgage or deed of
                         trust. Guarantor understands that the effect of the
                         foregoing waiver may be that Guarantor may have
                         liability hereunder for amounts with respect to which
                         Guarantor may be left without rights of subrogation,
                         reimbursement, contribution, or indemnity against
                         Debtor or other guarantors or sureties. Guarantor also
                         agrees that the "fair market value" provisions of
                         Section 580a of the California Code of Civil Procedure
                         shall have no applicability with respect to the
                         determination of Guarantor's liability under this
                         Guaranty.

                    q.   WITHOUT LIMITING THE GENERALITY OF ANY OTHER WAIVER OR

                         HEREBY WAIVES, TO THE MAXIMUM EXTENT SUCH WAIVER IS
                         PERMITTED BY LAW, ANY AND ALL BENEFITS OR DEFENSES
                         ARISING DIRECTLY OR INDIRECTLY UNDER ANY ONE OR MORE OF

<PAGE>

                         BY THE GUARANTIED PARTY, EVEN THOUGH THAT ELECTION OF
                         REMEDIES, SUCH AS A NONJUDICIAL FORECLOSURE WITH
                         RESPECT TO SECURITY FOR A GUARANTIED OBLIGATION, HAS
                         DESTROYED THE GUARANTOR'S RIGHTS OF SUBROGATION AND
                         REIMBURSEMENT AGAINST THE DEBTOR BY THE OPERATION OF
                         SECTION 580d OF THE CALIFORNIA CODE OF CIVIL PROCEDURE
                         OR OTHERWISE.

          (aa) Releases.  Guarantor consents and agrees that, without notice to
               --------
or by Guarantor and without affecting or impairing the obligations of Guarantor
hereunder, the Lender Group or Guarantied Party on behalf thereof may, by action
or inaction, compromise or settle, extend the period of duration or the time for
the payment, or discharge the performance of, or may refuse to, or otherwise not
enforce, or may, by action or inaction, release all or any one or more parties
to, any one or more of the terms and provisions of the Credit Agreement or any
of the other Loan Documents or may grant other indulgences to Debtor in respect
thereof, or may amend or modify in any manner and at any time (or from time to
time) any one or more of the Credit Agreement or any of the other Loan
Documents, or may, by action or inaction, release or substitute any other
guarantor, if any, of the Guarantied Obligations, or may enforce, exchange,
release, or waive, by action or inaction, any security for the Guarantied
Obligations or any other guaranty of the Guarantied Obligations, or any portion
thereof.

          (bb) No Election.  Guarantied Party shall have the right to seek
               -----------
recourse against Guarantor to the fullest extent provided for herein and no
election by the Lender Group or Guarantied Party on behalf thereof to proceed in
one form of action or proceeding, or against any party, or on any obligation,
shall constitute a waiver of Guarantied Party's right on behalf of the Lender
Group to proceed in any other form of action or proceeding or against other
parties unless Guarantied Party has expressly waived such right in writing.
Specifically, but without limiting the generality of the foregoing, no action or
proceeding by the Lender Group or Guarantied Party on behalf thereof under any
document or instrument evidencing the Guarantied Obligations shall serve to
diminish the liability of Guarantor under this Guaranty except to the extent
that the Lender Group finally and unconditionally shall have realized
indefeasible payment by such action or proceeding.

          (cc) Indefeasible Payment.  The Guarantied Obligations shall not be
               --------------------
considered indefeasibly paid for purposes of this Guaranty unless and until all
payments to the Lender Group are no longer subject to any right on the part of
any person whomsoever, including Debtor, Debtor as a debtor in possession, or
any trustee (whether appointed under the Bankruptcy Code or otherwise) of
Debtor's assets to invalidate or set aside such payments or to seek to recoup
the amount of such payments or any portion thereof, or to declare same to be
fraudulent or preferential. In the event that, for any reason, all or any
portion of such payments to the Lender Group is set aside or restored, whether
voluntarily or involuntarily, after the making thereof, the obligation or part
thereof intended to be satisfied thereby shall be revived and continued in full
force and effect as if said payment or payments had not been made and Guarantor
shall be liable for the full amount the Lender Group is required to repay plus
any and

                                       7.
<PAGE>

all costs and expenses (including attorneys fees) paid by the Lender Group in
connection therewith.

          (dd) Financial Condition of Debtor.  Guarantor represents and warrants
               -----------------------------
to Guarantied Party that it is currently informed of the financial condition of
Debtor and of all other circumstances which a diligent inquiry would reveal and
which bear upon the risk of nonpayment of the Guarantied Obligations. Guarantor
further represents and warrants to Guarantied Party that it has read and
understands the terms and conditions of the Credit Agreement and the other Loan
Documents. Guarantor hereby covenants that it will continue to keep itself
informed of Debtor's financial condition, the financial condition of other
guarantors, if any, and of all other circumstances which bear upon the risk of
nonpayment or nonperformance of the Guarantied Obligations.

          (ee) Subordination.  Guarantor hereby agrees that any and all present
               -------------
and future indebtedness of Debtor owing to Guarantor is postponed in favor of
and subordinated to payment, in full, in cash, of the Guarantied Obligations. In
this regard, no payment of any kind whatsoever shall be made with respect to
such indebtedness until the Guarantied Obligations have been indefeasibly paid
in full.

          (ff) Payments; Application.  All payments to be made hereunder by
               ---------------------
Guarantor shall be made in lawful money of the United States of America at the
time of payment, shall be made in immediately available funds, and shall be made
without deduction (whether for taxes or otherwise) or offset. All payments made
by Guarantor hereunder shall be applied as follows: first, to all reasonable
costs and expenses (including attorneys fees) incurred by Guarantied Party on
behalf of the Lender Group in enforcing this Guaranty or in collecting the
Guarantied Obligations; second, to all accrued and unpaid interest, premium, if
any, and fees owing to the Lender Group constituting Guarantied Obligations; and
third, to the balance of the Guarantied Obligations.

          (gg) Attorneys Fees and Costs.  Guarantor agrees to pay, on demand,
               ------------------------
all reasonable attorneys fees and all other reasonable costs and expenses which
may be incurred by Guarantied Party on behalf of the Lender Group in the
enforcement of this Guaranty or in any way arising out of, or consequential to
the protection, assertion, or enforcement of the Guarantied Obligations (or any
security therefor), irrespective of whether suit is brought.

other remedy, but each and every remedy shall be cumulative and in addition to
any and every other remedy given under this Guaranty, under the Credit

similar or dissimilar, right or default or otherwise prejudice the rights and
remedies hereunder.
