Guarantor                                    Obligor

        In consideration of, and as an inducement for BOSTON SAFE DEPOSIT AND
TRUST COMPANY (hereinafter called the "Lender") to make a mortgage loan to
WILLIAM E. MITCHELL and JAN SCHREYER MITCHELL (hereinafter collectively
referred to as the "Obligor"), in an aggregate principal amount not to exceed
One Million One Hundred Thousand and No/Hundreds Dollars ($1,100,000.00)
(hereinafter individually and collectively called the "Loan(s)"), the
undersigned, NASHUA CORPORATION,  a Delaware corporation (hereinafter called
the "Guarantor"), with its principal place of business at 44 Franklin Street,
Nashua, New Hampshire 03061, does hereby unconditionally and irrevocably
guarantee to the Lender and its successors and assigns, without offset or
deduction, the prompt payment when due, whether by acceleration or otherwise,
of all payments of the principal of and interest on the promissory notes from
time to time executed by the Obligor evidencing the Loan(s) (hereinafter
individually and collectively called the "Note"), and all other amounts
whatsoever now or hereafter owing and payable by the Obligor under, arising out
of or in connection with any Note evidencing the Loan(s), the guaranty under
this clause constituting hereby a guaranty of payment and not of collection.
The Guarantor does hereby agree that in the event that the Obligor does not or
is unable to pay or perform in accordance with the terms of the Note for any
reason (including, without limitation and to the extent applicable, the
liquidation, dissolution, receivership, insolvency, bankruptcy, assignment for
the benefit of creditors, reorganization, arrangement, composition or
readjustment of, or other similar proceedings affecting the status, existence,
assets or obligations of, the Obligor) it will pay the installments of
principal and interest (and premium, if any) due on such Note or otherwise
provide for and bring about promptly when due such payment and the performance
of such duties, agreements, covenants and obligations of the Obligor. 
Guarantor specifically and unconditionally agrees that if a petition in
bankruptcy or for an arrangement or reorganization of Guarantor under the
bankruptcy laws or for the appointment of a receiver for Obligor or Guarantor,
or any of the property of Obligor or Guarantor is filed by or against Obligor
or Guarantor, or if Obligor or Guarantor shall make an assignment for the
benefit of creditors or shall become insolvent, all Obligations of Obligor to
Lender shall, for purposes of this guaranty, be deemed at Lender's election to
have become immediately due and payable. Guarantor further agrees Lender may
declare all the Obligations due and payable for purposes of the Guaranty if
there is a material change in the financial status of Guarantor.  All of the
liabilities and obligations of the Obligor hereby guaranteed are hereinafter
collectively referred to as the "Obligations".

        Without limiting the generality of clause (i) above, the Guarantor
specifically agrees that it shall not be necessary or required, and that the
Guarantor shall not be entitled to require, that the Lender, or any successor
or assignee of Lender, file suit or proceed to obtain or assert a claim for
personal judgment against the Obligor for the Obligations or make any effort at
collection of the Obligations from the Obligor or foreclose against or seek to
realize upon any security now or hereafter existing for the Obligations or file
suit or proceed to obtain or assert a claim for personal judgment against any
other party liable for the Obligations or make any effort at collection of the
Obligations from any such other party or exercise or assert any other right or
remedy to which any of them is or may be entitled in connection with the
Obligations or any security or other guaranty therefor or assert or file any
claim against the assets of the Obligor or other person liable for the
Obligations, or any part thereof, before or as a condition of enforcing the
liability of the Guarantor under this Guaranty or requiring payment of said
Obligations by the Guarantor hereunder, or at any time thereafter.  The
Guarantor agrees, upon demand of the Lender to either, at the Lender's option,
pay directly or reimburse the Lender for the payment of, all costs, fees and
expenses, including, without limitation, attorneys' fees, incurred by the
Lender in the enforcement or attempted enforcement of any of its rights
hereunder.

required in order to enforce the obligations of the Guarantor hereunder that

this Guaranty and of the performance or nonperformance of any of the
Obligations; demand of payment from the Obligor except to the extent required
by the Note; presentment for payment upon the Obligor or the making of any
protest; notice of the amount of the Obligations outstanding at any time; and
notice of nonpayment or failure to perform on the part of the Obligor.  The
Guarantor further waives all defenses, offsets and counterclaims which the
Guarantor may at any time have to the payment or performance of the
Obligations.  The obligations of the Guarantor under this Guaranty shall be
absolute and unconditional and shall remain in full force and effect until the
Obligor shall have fully and satisfactorily discharged the Obligations and
shall not be released or discharged by reason of: (i) any waiver by the Lender,
or its successors or assigns, of the performance or observance by the Obligor
of any of the agreements, covenants, terms or conditions contained in the Note;
(ii) the extension of the time for payment by the Obligor of any payment of
principal and interest due on the Note or other sums or any part thereof owing
or payable under or pursuant to the Note, or any Loan or of the time for
performance by the Obligor of any other obligations under or pursuant to the
Note; (iii) any failure, omission or delay of the Lender or its successors or
assigns to enforce, assert or exercise any right, power or remedy conferred on
the Lender under or pursuant to the Note or any action on the part of the
Lender or its successors or assigns granting any extension or indulgence in any
form to the Obligor; (iv) any compromise, settlement, release, renewal,
extension, indulgence, change in or waiver or modification of, any of the
Obligations or the release or discharge of the Obligor from the performance or
observance of any of the Obligations by operation of law; (v) any change in,
waiver or modification of, or amendment to, any of the terms or provisions of
the Note; (vi) if applicable, any consolidation or merger of Obligor, whether
permitted under the terms of the Agreements or otherwise, or the sale, transfer
or other disposition by the Obligor or all or substantially all of the assets
and liabilities of the Obligor; (vii) if applicable, the voluntary or
involuntary liquidation, dissolution, receivership, insolvency, bankruptcy,
assignment for the benefit of 

                                      2

Obligor, or any other similar proceeding affecting the status, existence,
assets or obligations of the Obligor; (viii) if applicable, the death or mental
or physical incapacity of the Obligor; (ix) any fictitiousness, incorrectness,
invalidity or unenforceability, for any reason, of the Note or of any provision
thereof, or of any of the Obligations; (x) any transfer or assignment by the
Obligor of any of the Obligor's rights or obligations under the Note, or any
use of the Collateral (as defined in the Note) or any part thereof by any
person or party, or any sale, transfer, assignment, lease, mortgage, pledge,
hypothecation or further encumbering of the Collateral or any part thereof by
Obligor; or (xi) any other circumstance that might otherwise constitute a legal
or equitable discharge of the Obligor (including a discharge in bankruptcy) or
of the Guarantor.

Guarantor is a corporation duly organized, validly existing and in good
