                         Agreement; this Guaranty; and the other Loan Documents.
                         Neither this Guaranty nor any uncertainty or ambiguity
                         herein shall be construed or resolved against
                         Guarantied Party, the Lender Group, or Guarantor,
                         whether under any rule of construction or otherwise. On
                         the contrary, this Guaranty has been reviewed by
                         Guarantor, Guarantied Party, the several members of the
                         Lender Group, and their respective counsel, and shall
                         be construed and interpreted according to the ordinary
                         meaning of the words used so as to fairly accomplish
                         the purposes and intentions of Guarantied Party and
                         Guarantor.

                                       2.

          (b)  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.

          (c)  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.

          (d)  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.

          (e)  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
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

                                       3.
<PAGE>

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.

                    (f)  Waivers.
                         -------

                              c.   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.

                              d.   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 defense (other
                                   than the defense that the Guarantied
                                   Obligations shall have been fully and finally
                                   performed and indefeasibly paid)

                                       4.

                                   of Debtor or by reason of the cessation from
                                   any cause whatsoever of the liability of
                                   Debtor in respect thereof.

                              e.   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.

                              f.   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.

                              g.   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 manner permitted by law,
                                   before or after enforcing this Guaranty,
                                   without diminishing or affecting the
                                   liability of Guarantor

                                       5.

                                   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.

                              h.   WITHOUT LIMITING THE GENERALITY OF ANY OTHER
                                   WAIVER OR OTHER PROVISION SET FORTH IN THIS
                                   GUARANTY, GUARANTOR HEREBY WAIVES, TO THE

                                   REMEDIES BY THE GUARANTIED PARTY, EVEN THOUGH

                                   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.

          (g)  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.

          (h)  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.

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

                                       7.

          (j)  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.

          (k)  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.

          (l)  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.

          (m)  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.

Credit Agreement, or any other Loan Document is intended to be exclusive of any
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
Agreement, or any other Loan Document, and those provided by law. No delay or
omission by Guarantied Party to exercise any right under this Guaranty shall

consent shall be effective only to the extent specified therein and for the
specific purpose for which given. No course of dealing and no delay or waiver of
any right or default under this Guaranty shall be deemed a waiver of any other,
similar or dissimilar, right or default or otherwise prejudice the rights and
remedies hereunder.

               ----------------------
Guarantor and its successors and assigns and shall inure to the benefit of the
