and other good and valuable consideration paid or delivered to the undersigned
NEW PLAN REALTY TRUST, a Massachusetts business trust (hereinafter referred to
as "Guarantor"), the receipt and sufficiency whereof are hereby acknowledged by
Guarantor, and for the purpose of seeking to induce BANKBOSTON, N.A., a national
banking association (hereinafter referred to as "Lender", which term shall also
include each other Bank which may now be or hereafter become a party to the

benefit of Guarantor, Guarantor does hereby absolutely, unconditionally and
irrevocably guarantee to Lender:

         (a) the full and prompt payment when due, whether by acceleration or
otherwise, either before or after maturity thereof, of (i) that certain
Revolving Credit Note dated as of May 27, 1998, made by Borrower to the order of
BKB in the principal face amount of Thirty Million and No/100 Dollars

made by Borrower to the order of BKB in the principal face amount of Ten Million
and No/100 Dollars ($10,000,000.00) (hereinafter referred to collectively as the
"BKB Note"), and (ii) those certain Revolving Credit Notes (hereinafter referred
to as the "Additional Notes") dated various dates, made by Borrower to the order
of the Banks (other than BKB) in the aggregate principal face amount of Two
Hundred Twenty Million and No/100 Dollars ($220,000,000.00), together with
interest as provided in the BKB Note and the Additional Notes and together with
any replacements, supplements, renewals, modifications, consolidations,
restatements and extensions thereof; and

         (b) the full and prompt payment when due, whether by acceleration or

issued under that certain First Amended and Restated Revolving Credit Agreement
dated as of March 31, 1998 among Borrower and BKB, for itself and as agent, and
the other lenders now or hereafter a party thereto, as amended by that certain
First Amendment to Amended and Restated Revolving Credit Agreement dated of even
date herewith (hereinafter referred to as the "Credit Agreement") together with
interest as provided in each such note, together with any replacements,
supplements, renewals, modifications, consolidations, restatements and
extensions thereof (the BKB Note, the Additional Notes and each of the notes
described in this subparagraph (b) is hereinafter referred to collectively as
the "Note"); and


   2
         (c) the full and prompt payment and performance of all obligations of
Borrower to Lender under the terms of the Credit Agreement, including, without
limitation, the obligations of Borrower concerning hazardous materials contained
in Section 8.6 of the Credit Agreement, together with any replacements,
supplements, renewals, modifications, consolidations, restatements and
extensions thereof; and

         (d) the full and prompt payment and performance of any and all other
obligations of Borrower to Lender under any other agreements, documents or
instruments now or hereafter evidencing, securing or otherwise relating to the
indebtedness evidenced by the Note or the Credit Agreement (the Note, the Credit
Agreement and said other agreements, documents and instruments are hereinafter
collectively referred to as the "Loan Documents" and individually referred to as
a "Loan Document");

provided, however, the liability of Guarantor hereunder shall not exceed the
Maximum Amount for Guarantor. As used herein, the term "Maximum Amount" means
with respect to Guarantor, the greater of (i) 95% of the greater of (A) the
Asset Value of all Unencumbered Operating Properties from time to time owned by
Guarantor or (B) the Debt Service Coverage Amount for all Unencumbered Operating
Properties from time to time owned by Guarantor or (ii) 95% of the difference,
from time to time, of (a) the fair saleable value of the properties of Guarantor
minus (b) the total liabilities of Guarantor (including the probable liabilities
on contingent or unliquidated obligations, but excluding the obligations of
Guarantor hereunder). Upon any transfer of an Unencumbered Operating Property
from one person liable with respect to the obligations guaranteed hereunder to
another person liable with respect to the obligations guaranteed hereunder, the
consideration given in connection with such transfer shall be deemed to include
associated increase in the Maximum Amount of the transferee and decrease in the
Maximum Amount of the transferor.

All terms used herein and not otherwise defined herein shall have the meanings
set forth in the Credit Agreement.

         1. Agreement to Pay and Perform; Costs of Collection. Guarantor does
hereby agree that if the Note is not paid by Borrower in accordance with its
terms, or if any and all sums which are now or may hereafter become due from
Borrower to Lender under the Loan Documents are not paid by Borrower in
accordance with their terms, or if any and all other obligations of Borrower to
Lender under the Note and the Loan Documents are not performed by Borrower in
accordance with their terms, Guarantor will immediately make such payments and
perform such obligations. Guarantor further agrees to pay Lender on demand all
reasonable costs and expenses (including court costs and reasonable attorneys'
fees and disbursements) paid or incurred by Lender in endeavoring to collect the
indebtedness guaranteed hereby, to enforce any of the other obligations of
Borrower guaranteed hereby, or any portion thereof, or to enforce this Guaranty,
and until paid to Lender, such sums shall bear interest at the default rate set
forth in the Credit Agreement unless collection from Guarantor of interest at
such rate would be contrary to

                                      -2-
   3
applicable law, in which event such sums shall bear interest at the highest rate
which may be collected from Guarantor under applicable law.

         2. Reinstatement of Refunded Payments. If, for any reason, any payment
to Lender of any of the obligations guaranteed hereunder is required to be
refunded by Lender to Borrower, or paid or turned over to any other person,
including, without limitation, by reason of the operation of bankruptcy,
reorganization, receivership or insolvency laws or similar laws of general
application relating to creditors' rights and remedies now or hereafter enacted,
Guarantor agrees to pay the amount so required to be refunded, paid or turned
over (the "Turnover Payment"), the obligations of Guarantor shall not be treated
as having been discharged by the original payment to Lender giving rise to the
Turnover Payment, and this Guaranty shall be treated as having remained in full
force and effect for any such Turnover Payment so made by Lender, as well as for
any amounts not theretofore paid to Lender on account of such obligations.

         3. Rights of Lender to Deal with Collateral, Borrower and Other
Persons. Guarantor hereby consents and agrees that Lender may at any time, and
from time to time, without thereby releasing Guarantor from any liability
hereunder and without notice to or further consent from any other Person, either
with or without consideration: release or surrender any lien or other security
of any kind or nature whatsoever held by it or by any person, firm or
corporation on its behalf or for its account, securing any indebtedness or
liability hereby guaranteed; substitute for any collateral so held by it, other
collateral of like kind, or of any kind; modify the terms of the Note or the
Loan Documents; extend or renew the Note for any period; grant releases,
compromises and indulgences with respect to the Note or the Loan Documents and
to any persons or entities now or hereafter liable thereunder or hereunder;
release any other guarantor, surety, endorser or accommodation party of the Note
or any other Loan Documents; or take or fail to take any action of any type
whatsoever. No such action which Lender shall take or fail to take in connection
with the Note or the Loan Documents, or any of them, or any security for the
payment of the indebtedness of Borrower to Lender or for the performance of any
obligations or undertakings of Borrower, nor any course of dealing with Borrower
or any other person, shall release Guarantor's obligations hereunder, affect
this Guaranty in any way or afford Guarantor any recourse against Lender. The
provisions of this Guaranty shall extend and be applicable to all replacements,
supplements, renewals, amendments, extensions, consolidations, restatements and
modifications of the Note and the Loan Documents, and any and all references
herein to the Note and the Loan Documents shall be deemed to include any such
replacements, supplements, renewals, extensions, amendments, consolidations,
restatements or modifications thereof. Without limiting the generality of the
foregoing, Guarantor acknowledges the terms of Section 18.3 of the Credit
Agreement and agrees that this Guaranty shall extend and be applicable to each
new or replacement note delivered by Borrower pursuant thereto without notice to
or further consent from Guarantor.

         4. No Contest with Lender; Subordination. So long as any obligation
hereby guaranteed remains unpaid or undischarged, Guarantor will not, by paying
any sum recoverable hereunder (whether or not demanded by Lender) or by any
means or on any other ground, claim any set-off or counterclaim against Borrower
in respect of any liability of Guarantor to Borrower 

                                      -3-
   4
or, in proceedings under federal bankruptcy law or insolvency proceedings of any
nature, prove in competition with Lender in respect of any payment hereunder or
be entitled to have the benefit of any counterclaim or proof of claim or
dividend or payment by or on behalf of Borrower or the benefit of any other
security for any obligation hereby guaranteed which, now or hereafter, Lender
may hold or in which it may have any share. Guarantor hereby expressly waives
any right of contribution from or indemnity against Borrower, whether at law or
in equity, arising from any payments made by Guarantor pursuant to the terms of
this Guaranty, and Guarantor acknowledges that Guarantor has no right whatsoever
to proceed against Borrower for reimbursement of any such payments. In
connection with the foregoing, Guarantor expressly waives any and all rights of
subrogation to Lender against Borrower, and Guarantor hereby waives any rights
to enforce any remedy which Lender may have against Borrower and any rights to
participate in any collateral for Borrower's obligations under the Loan
Documents. Guarantor hereby subordinates any and all indebtedness of Borrower
now or hereafter owed to Guarantor to all indebtedness of Borrower to Lender,
and agrees with Lender that (a) Guarantor shall not demand or accept any payment
from Borrower on account of such indebtedness, (b) Guarantor shall not claim any
offset or other reduction of Guarantor's obligations hereunder because of any
such indebtedness, and (c) Guarantor shall not take any action to obtain any
interest in any of the security described in and encumbered by the Loan
Documents because of any such indebtedness; provided, however, that, if Lender
so requests, such indebtedness shall be collected, enforced and received by
Guarantor as trustee for Lender and be paid over to Lender on account of the
indebtedness of Borrower to Lender, but without reducing or affecting in any
manner the liability of Guarantor under the other provisions of this Guaranty
except to the extent the principal amount of such outstanding indebtedness shall
have been reduced by such payment.

         5. Waiver of Defenses. Guarantor hereby agrees that its obligations
hereunder shall not be affected or impaired by, and hereby waives and agrees not
to assert or take advantage of any defense based on:

                  (a) any statute of limitations in any action hereunder or for
the collection of the Note or for the payment or performance of any obligation
hereby guaranteed;

                  (b) the incapacity, lack of authority, death or disability of
Borrower or any other person or entity, or the failure of Lender to file or
enforce a claim against the estate (either in administration, bankruptcy or in
any other proceeding) of Borrower or Guarantor or any other person or entity;

                  (c) the dissolution or termination of existence of Borrower or
Guarantor or any other Person;

                  (d) the voluntary or involuntary liquidation, sale or other
disposition of all or substantially all of the assets of Borrower;

                                      -4-
   5
                  (e) the voluntary or involuntary receivership, insolvency,
bankruptcy, assignment for the benefit of creditors, reorganization, assignment,
composition, or readjustment of, or any similar proceeding affecting, Borrower
or Guarantor, or of Borrower's or any Guarantor's properties or assets;

                  (f) the damage, destruction, condemnation, foreclosure or
surrender of all or any part of the Real Estate or any of the improvements
located thereon;

                  (g) the failure of Lender to give notice of the existence,
creation or incurring of any new or additional indebtedness or obligation or of
any action or nonaction on the part of any other person whomsoever in connection
with any obligation hereby guaranteed;

                  (h) any failure or delay of Lender to commence an action
against Borrower, to assert or enforce any remedies against Borrower under the
Note or the Loan Documents, or to realize upon any security;

                  (i) any failure of any duty on the part of Lender to disclose
to Guarantor any facts it may now or hereafter know regarding Borrower, the Real
Estate or any of the improvements located thereon, whether such facts materially
increase the risk to Guarantor or not;

                  (j) failure to accept or give notice of acceptance of this
Guaranty by Lender;

                  (k) failure to make or give notice of presentment and demand
for payment of any of the indebtedness or performance of any of the obligations
hereby guaranteed;

                  (l) failure to make or give protest and notice of dishonor or
of default to Guarantor or to any other party with respect to the indebtedness
or performance of obligations hereby guaranteed;

                  (m) except as otherwise specifically provided in this
Guaranty, any and all other notices whatsoever to which Guarantor might
otherwise be entitled;

                  (n) any lack of diligence by Lender in collection, protection
or realization upon any collateral securing the payment of the indebtedness or
performance of obligations hereby guaranteed;

                  (o) the invalidity or unenforceability of the Note or any of
the Loan Documents;

                  (p) the compromise, settlement, release or termination of any
or all of the obligations of Borrower under the Note or the Loan Documents;

                                      -5-
   6
                  (q) any transfer by Borrower or any other Person of all or any
part of the security encumbered by the Loan Documents;

                  (r) the failure of Lender to perfect any security or to extend
or renew the perfection of any security; or

                  (s) to the fullest extent permitted by law, any other legal,
equitable or surety defenses whatsoever to which Guarantor might otherwise be
entitled, it being the intention that the obligations of Guarantor hereunder are
absolute, unconditional and irrevocable.

         6. Guaranty of Payment and Performance and Not of Collection. This is a
Guaranty of payment and performance and not of collection. The liability of
Guarantor under this Guaranty shall be primary, direct and immediate and not
conditional or contingent upon the pursuit of any remedies against Borrower or
any other person, nor against securities or liens available to Lender, its
successors, successors in title, endorsees or assigns. Guarantor hereby waives
any right to require that an action be brought against Borrower or any other
person or to require that resort be had to any security or to any balance of any
deposit account or credit on the books of Lender in favor of Borrower or any
other person.

         7. Rights and Remedies of Lender. In the event of a default under the
Note or the Loan Documents, or any of them, Lender shall have the right to
enforce its rights, powers and remedies thereunder or hereunder or under any
other agreement, document or instrument now or hereafter evidencing, securing or
otherwise relating to the indebtedness evidenced by the Note or secured by the
Loan Documents, in any order, and all rights, powers and remedies available to
Lender in such event shall be nonexclusive and cumulative of all other rights,
powers and remedies provided thereunder or hereunder or by law or in equity.
Accordingly, Guarantor hereby authorizes and empowers Lender upon the occurrence
of any event of default under the Note or the Loan Documents, at its sole
discretion, and without notice to Guarantor, to exercise any right or remedy
which Lender may have, including, but not limited to, judicial foreclosure,
exercise of rights of power of sale, acceptance of a deed or assignment in lieu
of foreclosure, appointment of a receiver to collect rents and profits, exercise
of remedies against personal property, or enforcement of any assignment of
leases, as to any security, whether real, personal or intangible. At any public
or private sale of any security or collateral for any indebtedness or any part
thereof guaranteed hereby, whether by foreclosure or otherwise, Lender may, in
its discretion, purchase all or any part of such security or collateral so sold
or offered for sale for its own account and may apply against the amount bid
therefor all or any part of the balance due it pursuant to the terms of the Note
or any other Loan Document without prejudice to Lender's remedies hereunder
against Guarantor for deficiencies. If the indebtedness guaranteed hereby is
partially paid by reason of the election of Lender to pursue any of the remedies
available to Lender, or if such indebtedness is otherwise partially paid, this
Guaranty shall nevertheless remain in full force and effect, and Guarantor shall
remain liable for the entire balance of the indebtedness guaranteed hereby even
though any rights which Guarantor may have against Borrower may be destroyed or
diminished by the exercise of any such remedy.

                                      -6-
   7
         8. Application of Payments. Guarantor hereby authorizes Lender, without
notice to Guarantor, to apply all payments and credits received from Borrower or
from Guarantor or realized from any security in such manner and in such priority
as Lender in its sole judgment shall see fit to the indebtedness, obligation and
undertakings which are the subject of this Guaranty.

         9. Business Failure, Bankruptcy or Insolvency. In the event of the
business failure of Guarantor or if there shall be pending any bankruptcy or
insolvency case or proceeding with respect to Guarantor under federal bankruptcy
law or any other applicable law or in connection with the insolvency of
Guarantor, or if a liquidator, receiver, or trustee shall have been appointed
for Guarantor or Guarantor's properties or assets, Lender may file such proofs
of claim and other papers or documents as may be necessary or advisable in order
to have the claims of Lender allowed in any proceedings relative to Guarantor,
or any of Guarantor's properties or assets, and, irrespective of whether the
indebtedness or other obligations of Borrower guaranteed hereby shall then be
due and payable, by declaration or otherwise, Lender shall be entitled and
empowered to file and prove a claim for the whole amount of any sums or sums
owing with respect to the indebtedness or other obligations of Borrower
guaranteed hereby, and to collect and receive any moneys or other property
payable or deliverable on any such claim. Guarantor covenants and agrees that
upon the commencement of a voluntary or involuntary bankruptcy proceeding by or
against Borrower, Guarantor shall not seek a supplemental stay or otherwise
pursuant to 11 U.S.C. Section 105 or any other provision of the Bankruptcy
Reform Act of 1978, as amended, or any other debtor relief law (whether
statutory, common law, case law, or otherwise) of any jurisdiction whatsoever,
now or hereafter in effect, which may be or become applicable, to stay,
interdict, condition, reduce or inhibit the ability of Lender to enforce any
rights of Lender against Guarantor by virtue of this Guaranty or otherwise.

         10. Financial Statements and Other Information. Guarantor hereby
represents and warrants to Lender that all financial statements of Guarantor and
its Subsidiaries heretofore delivered by Guarantor to Lender are true and
correct in all material respects, have been prepared in accordance with
generally accepted accounting principles consistently applied, and fairly
present the financial condition of Guarantor and its Subsidiaries as at the
close of business on the date thereof and the results of operations for the
period then ended; that no material adverse change has occurred in the assets,
liabilities, financial condition or business of Guarantor and its Subsidiaries
as shown or reflected therein since the date thereof; and that Guarantor and its
Subsidiaries have no liabilities or known contingent liabilities involving
material amounts which are not reflected in such financial statements or
referred to in the notes thereto other than Guarantor's obligations under this
Guaranty. Guarantor hereby agrees that until all indebtedness guaranteed hereby
has been completely repaid, all obligations and undertakings of Borrower under,
by reason of, or pursuant to the Note and the Loan Documents have been
completely performed and Lender has no further obligation to make Loans to
Borrower pursuant to the Credit Agreement, Guarantor will deliver to Lender:

                                      -7-
   8
                  (a) as soon as practicable and in any event within 90 days
after the end of each fiscal year of Guarantor, copies of the unaudited
consolidated balance sheet of Guarantor and its Subsidiaries as of the end of
such fiscal year, and the related unaudited consolidated statement of operations
and statement of cash flows for such fiscal year, all in reasonable detail and
prepared in accordance with generally accepted accounting principals, together
with a certificate by the principal financial or accounting officer of Guarantor
that the information contained in such financial statements fairly presents the
financial portion of Guarantor on the date thereof;

                  (b) contemporaneously with the delivery of the financial
statements referred to in clause (a) above, a statement of all contingent
liabilities of Guarantor and its Subsidiaries which are not reflected in such
financial statements or referred to in the notes thereto (including, without
limitation, all guarantees, endorsements and other contingent obligations in
respect of indebtedness of others, and obligations to reimburse the issuer in
respect of any letters of credit), all in reasonable detail and certified by the
principal financial or accounting officer of Guarantor;

                  (c) promptly after they are filed with the Internal Revenue
Service, copies of all annual federal income tax returns and amendments thereto
of Guarantor;

                  (d) concurrently with the delivery of the financial statements
described in clause (a) above, a certificate signed by the president or chief
financial officer of Guarantor to the effect that, having read this Guaranty,
and that based upon an examination which they deem sufficient to enable them to
make an informed statement, there does not exist any Default or Event of
Default, or if such Default or Event of Default has occurred, specifying the
facts with respect thereto;

                  (e) promptly upon becoming aware thereof, written notice from
Guarantor of any event or condition which might have a material adverse effect
on the business, operations, assets, condition (financial or otherwise) or
prospects of Guarantor or any of its Subsidiaries or the ability of Guarantor to
perform under this Guaranty (including but not limited to, litigation commenced
or threatened in writing against Guarantor or any of its Subsidiaries, judgments
rendered against Guarantor or any of its Subsidiaries, liens filed against any
property of Guarantor, defaults claimed under indebtedness for borrowed money
for which Guarantor or any of its Subsidiaries is primarily or secondarily
liable, or bankruptcy, insolvency or trustee or receivership proceedings
commenced against Guarantor or any of its Subsidiaries), such notice to specify
the nature and the period of existence of such event or condition, the
anticipated effect thereof, and what action Guarantor is taking or proposes to
take with respect thereto; and

                  (f) with reasonable promptness, such other information
respecting the business, operations, assets, liabilities and financial condition
of Guarantor and its Subsidiaries as Lender may from time to time reasonably
request. Without limiting the foregoing, Lender may require that Guarantor
deliver to Lender financial information concerning Guarantor and its

                                      -8-
   9
Subsidiaries on a more frequent basis, including without limitation the delivery
of unaudited quarterly financial statements.

Guarantor will permit any officer designated by Lender, at Guarantor's expense,
to visit and inspect any of the properties of Guarantor and its Subsidiaries, to
examine the records and books of account of Guarantor and its Subsidiaries (and
to make copies thereof and extracts therefrom) and to discuss the affairs,
finances and accounts of Guarantor with, and to be advised as to the same by,
its officers, all at such reasonable times and intervals Lender may reasonably
request.

         11. Covenants of Guarantor. Guarantor hereby covenants and agrees with
Lender that until all indebtedness guaranteed hereby has been completely repaid,
all obligations and undertakings of Borrower under, by reason of, or pursuant to
the Note and the Loan Documents have been completely performed and Lender has no
further obligation to make Loans to Borrower pursuant to the Credit Agreement:

                  (a) Guarantor will, and will cause each of its Subsidiaries
to, do or cause to be done all things necessary to preserve and keep in full
force and effect its corporate or legal existence, material rights and
franchises, as applicable, to effect and maintain its foreign qualifications,
licensing, domestication or authorization in each jurisdiction where the
Unencumbered Operating Properties owned by it are located and in each other
jurisdiction where a failure to be so qualified could have a materially adverse
effect on the business, assets or financial condition of such person, and to
comply with all applicable laws and regulations (including, without limitation,
environmental laws);

                  (b) Guarantor will, and will cause each of its Subsidiaries
to, duly pay and discharge, before the same shall become in arrears, all taxes,
assessments and other governmental charges imposed upon it and its properties,
sales or activities, or upon the income or profits therefrom, as well as claims
for labor, material, or supplies which if unpaid might become a lien or charge
on any of its property; provided that any such tax, assessment, charge or claim
need not be paid if the validity or amount thereof shall currently be contested
in good faith by appropriate proceedings and if Guarantor or such Subsidiary
shall have set aside on its books adequate reserves with respect thereto; and
provided further that Guarantor or such Subsidiary shall pay all such taxes,
assessments, charges and claims forthwith upon the commencement of proceedings
to foreclose any lien that may have attached as security therefor;

                  (c) Guarantor will, and will cause each of its Subsidiaries
to, maintain and keep the properties used or deemed by it to be useful in its
business in first-class repair, working order and condition, and make or cause
to be made all necessary and proper repairs thereto and replacements thereof;

                  (d) Guarantor will, and will cause each of its Subsidiaries
to, maintain with financially sound and reputable insurers, insurance with
respect to its properties and business 

                                      -9-
   10
against such casualties and contingencies and in such types and amounts as shall
be in accordance with sound business practices for companies in similar business
similarly situated;

                  (e) Guarantor will keep, and will cause each of its
Subsidiaries to keep, complete, proper and accurate records and books of account
in which full, true and correct entries will be made in accordance with
generally accepted accounting principles consistent with the preparation of the
financial statements heretofore delivered to Lender and will maintain adequate
accounts and reserves for all taxes (including income taxes), all depreciation,
depletion, and amortization of its properties and the properties of its
Subsidiaries, all other contingencies, and all other proper reserves;

                  (f) Guarantor will not, and will not permit any of its
Subsidiaries to, create, incur, assume, guarantee or be or remain liable,
contingently or otherwise, with respect to any Indebtedness other than:

                  (i) Indebtedness to Lender arising under any of the Note, the
         Loan Documents and this Guaranty;

                  (ii) current liabilities of Guarantor incurred in the ordinary
         course of business but not incurred through the borrowing of money or
         the obtaining of credit except for credit on an open account basis
         customarily extended and in fact extended in connection with normal
         purchases of goods and services;

                  (iii) Indebtedness in respect of taxes, assessments and
         governmental charges to the extent that payment therefor shall not at
         the time be required to be made in accordance with the provisions of
         subparagraph (b) of this paragraph;

                  (iv) Indebtedness in respect of judgments or awards that have
         been in force for less than the applicable period for taking an appeal
         so long as execution is not levied thereunder or in respect of which
         Guarantor shall at the time in good faith be prosecuting an appeal or
         proceedings for review and in respect of which a stay of execution
         shall have been obtained pending such appeal or review;

Majority Banks;

                  (i) Guarantor will not, and will not permit any of its
Subsidiaries to, become a party to or agree to or affect any disposition of
assets, other than the disposition of assets in the ordinary course of business

obligations hereunder, a continuing lien on and security interest in any and all
securities or other property belonging to Guarantor now or hereafter held by

provisional or final, regardless of currency, maturity, or the branch of Lender
where the deposits are held) now or hereafter held by Lender and other sums
credited by or due from Lender to Guarantor or subject to withdrawal by
Guarantor; and regardless of the adequacy of any collateral or other means of
obtaining repayment of such obligations, during the continuance of any Event of
Default under the Note or the Loan Documents, Lender may at any time and without
notice to Guarantor set-off and apply the whole or any portion or portions of
any or all such deposits and other sums against amounts payable under this
Guaranty, whether or not any other person or persons could also withdraw money
therefrom. Any security now or hereafter held by or for Guarantor and provided
by Borrower, or by anyone on Borrower's behalf, in respect of liabilities of
Guarantor hereunder shall be held in trust for Lender as security for the
liabilities of Guarantor hereunder.

         13. Changes in Writing; No Revocation. This Guaranty may not be changed
orally, and no obligation of Guarantor can be released or waived by Lender
except by a writing signed by a duly authorized officer of Lender. This Guaranty
shall be irrevocable by Guarantor until all indebtedness guaranteed hereby has
been completely repaid and all obligations and undertakings of Borrower under,
by reason of, or pursuant to the Note and the Loan Documents have been
completely performed and Borrower has no further rights to receive Loans under
the Credit Agreement.

         14. Notices. All notices, demands or requests provided for or permitted
to be given pursuant to this Guaranty (hereinafter in this paragraph referred to
as "Notice") must be in writing and shall be deemed to have been properly given
or served by personal delivery or by sending same by overnight courier or by
depositing the same in the United States mail, postpaid and registered or
certified, return receipt requested, at the addresses set forth below. Each
Notice shall be effective upon being delivered personally or upon being sent by
overnight courier or upon being deposited in the United States Mail as
aforesaid. The time period in which a response to any such Notice must be given
or any action taken with respect thereto, however, shall commence to run from
the date of receipt if personally delivered or sent by overnight courier or, if
so deposited in the United States Mail, the earlier of three (3) Business Days
following such deposit and the date of receipt as disclosed on the return
receipt. Rejection or other refusal to accept or the inability to deliver
because of changed address of which no Notice was given shall be deemed to be
receipt of the Notice sent. By giving at least fifteen (15) days prior Notice
thereof, Guarantor or Lender shall have the right from time to time and at any
time during the term of this Guaranty to change their respective addresses and
each shall have the 

                                      -12-

         15. GOVERNING LAW. GUARANTOR ACKNOWLEDGES AND AGREES THAT THIS GUARANTY
AND THE OBLIGATIONS OF GUARANTOR HEREUNDER SHALL BE GOVERNED BY AND INTERPRETED
AND DETERMINED IN ACCORDANCE WITH THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS
(EXCLUDING THE LAWS APPLICABLE TO CONFLICTS OR CHOICE OF LAW).

         If, notwithstanding the provisions of Section 15 above, this Guaranty
is deemed to be governed by California law, then the following shall apply but
shall not in any way limit the generality of any other provisions contained in
this Guaranty.

         Guarantor hereby waives (a) any defense of Guarantor based upon
Lender's election of any remedy against Guarantor or Borrower or both; (b) any
defense based upon Lender's failure to disclose to Guarantor any information
concerning Borrower's financial condition or any other circumstances bearing on
Borrower's ability to pay all sums payable under the Loan Documents;

                                      -13-
   14
(c) any defense based upon any statute or rule of law which provides that the
obligation of a surety must be neither larger in amount nor in any other
respects more burdensome than that of a principal; (d) any defense based upon
Lender's election, in any proceeding instituted under the Federal Bankruptcy
Code, of the application of Section 1111(b)(2) of the Federal Bankruptcy Code or
any successor statute; (e) any right of subrogation, any right to enforce any
remedy which Lender may have against Borrower and any right to participate in,
or benefit from, any security for any of the Loan Documents now or hereafter
held by Lender; and (f) benefit of any statute of limitations affecting the
liability of Guarantor hereunder or the enforcement hereof. Without limiting the
generality of the foregoing or any other provision hereof, Guarantor expressly
waives any and all benefits which might otherwise be available to Guarantor
under Sections 2787 to 2855, inclusive, of the California Civil Code, including
without limitation, Sections 2809, 2810, 2819, 2839, 2845, 2849 and 2850, and
all benefits which might otherwise be available to Guarantor under Sections 2899
and 3433 of the California Civil Code and the California Code of Civil Procedure
Sections 580a, 580b, 580d and 726, or any of such sections. Furthermore, without
limitation of any waiver otherwise set forth herein, Guarantor waives all rights
and defenses arising out of an election of remedies by the Lender even though
that election of remedies, such as a nonjudicial foreclosure with respect to the
security for a guaranteed obligation, has destroyed Guarantor's rights of
subrogation and reimbursement against the principal by operation of Section 580d
of the California Code of Civil Procedure or otherwise.

         16. CONSENT TO JURISDICTION; WAIVERS. GUARANTOR HEREBY IRREVOCABLY AND
UNCONDITIONALLY (A) SUBMITS TO PERSONAL JURISDICTION IN THE COMMONWEALTH OF
MASSACHUSETTS OVER ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO
THIS GUARANTY, AND (B) WAIVES ANY AND ALL PERSONAL RIGHTS UNDER THE LAWS OF ANY
STATE (I) TO THE RIGHT, IF ANY, TO TRIAL BY JURY(LENDER HAVING ALSO WAIVED SUCH
RIGHT TO TRIAL BY JURY), (II) TO OBJECT TO JURISDICTION WITHIN THE COMMONWEALTH
OF MASSACHUSETTS OR VENUE IN ANY PARTICULAR FORUM WITHIN THE COMMONWEALTH OF
MASSACHUSETTS, AND (III) TO THE RIGHT, IF ANY, TO CLAIM OR RECOVER ANY SPECIAL,
EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER THAN OR IN
ADDITION TO ACTUAL DAMAGES. EACH LENDER IRREVOCABLY AND UNCONDITIONALLY WAIVES
ANY AND ALL RIGHTS UNDER THE LAWS OF ANY STATE TO THE RIGHT, IF ANY, TO TRIAL BY
JURY. GUARANTOR AGREES THAT, IN ADDITION TO ANY METHODS OF SERVICE OF PROCESS
PROVIDED FOR UNDER APPLICABLE LAW, ALL SERVICE OF PROCESS IN ANY SUCH SUIT,
ACTION OR PROCEEDING MAY BE MADE BY CERTIFIED OR REGISTERED MAIL, RETURN RECEIPT
REQUESTED, DIRECTED TO GUARANTOR AT THE ADDRESS SET FORTH IN PARAGRAPH 14 ABOVE,
AND SERVICE SO MADE SHALL BE COMPLETE FIVE (5) DAYS AFTER THE SAME SHALL BE SO
MAILED. NOTHING CONTAINED HEREIN, HOWEVER, SHALL PREVENT LENDER FROM BRINGING
ANY SUIT, ACTION OR PROCEEDING OR EXERCISING ANY RIGHTS AGAINST ANY SECURITY AND

                                      -14-
   15
AGAINST GUARANTOR PERSONALLY, AND AGAINST ANY PROPERTY OF GUARANTOR, WITHIN ANY
OTHER STATE. INITIATING SUCH SUIT, ACTION OR PROCEEDING OR TAKING SUCH ACTION IN
ANY STATE SHALL IN NO EVENT CONSTITUTE A WAIVER OF THE AGREEMENT CONTAINED
HEREIN THAT THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS SHALL GOVERN THE
RIGHTS AND OBLIGATIONS OF GUARANTOR AND LENDER HEREUNDER OR OF THE SUBMISSION
HEREIN MADE BY GUARANTOR TO PERSONAL JURISDICTION WITHIN THE COMMONWEALTH OF
MASSACHUSETTS. GUARANTOR HEREBY WAIVES ANY OBJECTION THAT IT MAY NOW OR
HEREAFTER HAVE TO THE VENUE OF ANY SUCH SUIT OR ANY SUCH COURT OR THAT SUCH SUIT
IS BROUGHT IN AN INCONVENIENT COURT. GUARANTOR CERTIFIES THAT NO REPRESENTATIVE,
AGENT OR ATTORNEY OF ANY LENDER HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT
SUCH LENDER WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING
WAIVERS AND ACKNOWLEDGES THAT LENDER HAS BEEN INDUCED TO ENTER INTO THIS
GUARANTY AND THE OTHER LOAN DOCUMENTS TO WHICH THEY ARE PARTIES BY, AMONG OTHER
THINGS, THE WAIVERS AND CERTIFICATIONS CONTAINED IN THIS PARAGRAPH 16. GUARANTOR
ACKNOWLEDGES THAT IT HAS HAD AN OPPORTUNITY TO REVIEW THIS PARAGRAPH 16 WITH ITS
LEGAL COUNSEL AND THAT GUARANTOR AGREES TO THE FOREGOING AS ITS FREE, KNOWING
AND VOLUNTARY ACT.

         17. Successors and Assigns. The provisions of this Guaranty shall be
binding upon Guarantor and its heirs, successors, successors in title, legal
representatives, and assigns, and shall inure to the benefit of Lender, its
successors, successors in title, legal representatives and assigns.

         18. Assignment by Lender. This Guaranty is assignable by Lender in
whole or in part in conjunction with any assignment of the Note or portions
thereof, and any assignment hereof or any transfer or assignment of the Note or
portions thereof by Lender shall operate to vest in any such assignee the rights
and powers, in whole or in part, as appropriate, herein conferred upon and
granted to Lender.

         19. Severability. If any term or provision of this Guaranty shall be
determined to be illegal or unenforceable, all other terms and provisions hereof
shall nevertheless remain effective and shall be enforced to the fullest extent
permitted by law.

         20. Disclosure. Guarantor agrees that in addition to disclosures made
in accordance with standard banking practices, any Lender may disclose
information obtained by such Lender pursuant to this Guaranty to assignees or
participants and potential assignees or participants hereunder.

                                      -15-

AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,

         22. Time of the Essence. Time is of the essence with respect to each
and every covenant, agreement and obligation of Guarantor under this Guaranty.

         23. Ratification. Guarantor does hereby restate, reaffirm and ratify
each and every warranty and representation regarding Guarantor or its
Subsidiaries set forth in the Credit Agreement as if the same were more fully
set forth herein.

each of which when so executed and delivered shall be an original, and all of
which together shall constitute one instrument. In proving this Guaranty it
shall not be necessary to produce or account for more than one such counterpart
signed by the party against whom enforcement is sought.
