                    REVOLVING LINE OF CREDIT PROMISSORY NOTE
                    ----------------------------------------


$30,000,000.00 U.S.                           Manchester, New Hampshire
                                              December 26, 1997


     FOR VALUE RECEIVED, the undersigned, WPI GROUP, INC., WPI ELECTRONICS,
INC., WPI MAGNETEC, INC., WPI MICRO PALM, INC., WPI POWER SYSTEMS, INC., WPI
TERMIFLEX, INC., WPI MICRO PROCESSOR SYSTEMS, INC., WPI DECISIONKEY, INC., WPI
UK HOLDING, INC., WPI UK HOLDING, II, INC., and WPI OYSTER TERMINALS, INC., each
a New Hampshire corporation, and WPI HUSKY COMPUTERS, INC, a Florida
corporation, all such corporations having executive offices at 1155 Elm Street
Manchester, New Hampshire 03101 (all of such corporations are hereinafter
referred to individually and collectively as the "Borrower"), hereby promise,
jointly and severally, to pay to the order of FLEET BANK - NH, a bank organized
under the laws of the State of New Hampshire with an address of Mail Stop NHNA
E02A, 1155 Elm Street, Manchester, New Hampshire 03101 (the "Bank"), at such
address, or such other place or places as the holder hereof may designate in
writing from time to time hereafter, the maximum principal sum of THIRTY MILLION
DOLLARS ($30,000,000.00), or so much thereof as may be advanced or readvanced by
the Bank to the Borrower from time to time hereafter (such amounts defined as
the "Debit Balance" below), together with interest as provided for hereinbelow,
in lawful money of the United States in immediately available funds, all as
provided hereinbelow.

     The Borrower's "Debit Balance" shall mean the debit balance in an account
on the books of the Bank, maintained in the form of a ledger card, computer
records or otherwise in accordance with the Bank's customary practice and
appropriate accounting procedures wherein there shall be recorded the principal
amount of all advances and readvances made by the Bank to the Borrower, all
principal payments made by the Borrower to the Bank hereunder, and all other
appropriate debits and credits to principal.  The Bank shall render to the
Borrower a statement of account with respect thereto on a monthly basis.  The
statement shall be considered correct and be considered accepted by the
Borrower, and shall conclusively bind the Borrower, unless Borrower notifies the
Bank to the contrary within thirty (30) days after the date of Borrower's
receipt of the statement.

     The Bank agrees to lend to the Borrower, and the Borrower may borrow, up to
the maximum principal sum provided for in this Note in accordance with and
subject to the terms, conditions, and limitations of this Note and the Amended
and Restated Commercial Loan Agreement dated as of December 26, 1997, as the
same may be amended from time to time hereafter (the "Loan Agreement").  The
holder of this Note is entitled to all of the benefits and rights, and is
subject to all of the obligations, of the Bank under the Loan Agreement.
However, neither this reference to the Loan Agreement nor any provision thereof
shall impair the absolute and unconditional obligation of the Borrower to pay
the principal and interest of this Note as 
<PAGE>
 
herein provided. Capitalized terms not otherwise defined herein shall have the
meanings ascribed to them in the Loan Agreement.

     The Borrower agrees that the Bank may deliver all advances under this Note
by direct deposit to any demand account of the Borrower with the Bank or in such
other reasonable manner as may be designated in writing by the Bank to the
Borrower, and that all such advances shall represent binding obligations of the
Borrower.

     The Borrower acknowledges that this Note is to evidence the Borrower's
obligation to pay its Debit Balance, plus interest and any other applicable
charges as determined from time to time, and that it shall continue to do so
despite the occurrence of intervals when no Debit Balance exists because the
Borrower has paid the previously existing Debit Balance in full.

     Interest shall be calculated and charged daily, based on the actual days
elapsed over a three hundred sixty (360) day banking year, on the Debit Balance
outstanding from time to time at an annual variable rate equal to the Prime
Rate.  The "Prime Rate" shall be the rate published by The Wall Street Journal
                                                       -----------------------
from time to time under the category "Prime Rate:  The Base Rate on Corporate
Loans posted by at least 75% of the Nation's 30 Largest Banks" (the lowest of
the rates so published if more than one rate is published under this category at
any given time) or such other comparable index rate selected by the Bank in its
sole discretion if The Wall Street Journal ceases to publish such rate.  The
                   -----------------------                                  
BORROWER acknowledges that the Prime Rate is used for reference purposes only as
an index and is not necessarily the lowest interest rate charged by the BANK on
commercial loans.  Each time the Prime Rate changes the interest rate hereunder
shall change contemporaneously with such change in the Prime Rate.
Notwithstanding the foregoing, the Borrower may elect from time to time a fixed
rate of interest equal to the Eurodollar Based Rate to apply to outstanding
principal hereunder, all in accordance with, and subject to the limitations of,
the provisions of the Loan Agreement.

     Outstanding principal hereunder shall be paid in accordance with the terms
and conditions of the Loan Agreement.  Accrued interest only on the outstanding
Debit Balance hereunder shall be payable monthly in arrears commencing thirty
(30) days from the date hereof (or on any day within 30 days of the date hereof
agreed to by the Borrower and the Bank to provide for a convenient payment date)
and continuing on the same date of each month thereafter through and until the
Review Date as to which the Bank does not renew the Revolving Line of Credit
Loan, whereupon all outstanding principal and accrued and unpaid interest
hereunder shall be due and payable in full.

     The Borrower may prepay this Note in whole or in part at any time;
provided, however, that such prepayment shall be subject to the terms and
conditions of the Loan Agreement and the charges provided thereunder payable by
Borrower to Bank.  In the event that any such prepayment shall be made by the
Borrower, the amount thereof shall be applied first to accrued interest and
thereafter to principal.

     At the option of the Bank, this Note shall become immediately due and
payable in full, without further demand or notice, if any installment of
principal or interest is not paid when due hereunder or upon the occurrence of
any other Event of Default under the terms hereof, of the Loan Agreement, or of
any other Loan Document.
<PAGE>
 
     The holder may impose upon the Borrower a delinquency charge of five
percent (5%) of the amount of the principal and/or interest not paid on or
before the tenth (10th) day after such installment is due.  The entire principal
balance hereof shall after maturity, whether by demand, acceleration or
otherwise, or following the occurrence of an Event of Default, until the Event
of Default has been cured or waived by the Bank, bear interest at the contract
rate of this Note plus an additional five percent (5%) per annum.

     The Borrower grants to Bank the right to set off and apply, upon the
occurrence of an Event of Default and without demand or notice of any nature,
all, or any portion of, deposits, credits and other property now or hereafter
due from the holder to the Borrower, against the indebtedness evidenced by this
Note.  This Note is secured by the Collateral granted in the Loan Agreement and
the other Loan Documents.

     The Borrower agrees to pay on demand all reasonable out-of-pocket costs of
collection hereof, including reasonable attorneys' fees, whether or not any
action is instituted by the holder in its discretion.

     No delay or omission on the part of the holder in exercising any right,
privilege or remedy shall impair such right, privilege or remedy or be construed
as a waiver thereof or of any other right, privilege or remedy.  No waiver of
any right, privilege or remedy under this Note shall be effective unless made in
writing and signed by the holder.  Under no circumstances shall an effective
waiver of any right, privilege or remedy on any one occasion constitute or be
construed as a bar to the exercise of or a waiver of such right, privilege or
remedy on any future occasion.

     The acceptance by the holder hereof of any payment after any default
hereunder shall not operate to extend the time of payment of any amount then
remaining unpaid hereunder or constitute a waiver of any rights of the holder
hereof under this Note.

     All rights and remedies of the holder, whether granted herein or otherwise,
shall be cumulative and may be exercised singularly or concurrently.

     The Borrower hereby waives, to the fullest extent permitted by law,
presentment, notice, and protest.  Borrower assents to any extension of the time
of payment or any other indulgence.

     This Note and the provisions, hereof shall be binding upon the Borrower and
the Borrower's successors, legal representatives and assigns and shall inure to
the benefit of and shall bind the holder and the holder's successors, legal
representatives and assigns.

     The word "holder" as used herein shall mean the payee or endorsee of this
Note who is in possession of it, or the bearer, if this Note is at the time
payable to the bearer.
