2.   Interim Financial Statements

     The financial information for the six months ending December 31, 1999 is
unaudited but includes all adjustments (consisting only of normal recurring
adjustments) which the Company considers necessary for a fair presentation of
the financial position at such date and of the operating results and cash flows
for these periods. The results of operations and cash flows for the six months
ended December 31, 1999 are not necessarily indicative of results that may be
expected for the entire year. The information contained in the Form 10QSB should
be read in conjunction with the Company's audited financial statements, included
it its Form 10KSB as of and for the year ending June 30, 1999 filed with the
Securities and Exchange Commission.

3.   Earnings per Share

     In 1998, the Company adopted the provisions of Statement of Financial
Accounting Standards No. 128, Earnings per Share. This Standard revises certain
methodology for computing earnings per common share (EPS) and requires the
reporting of two earnings per share figures: basic earnings per share and
diluted earnings per share. Basic earnings per common share are computed by
dividing net income by the weighted-average number of common shares outstanding.
Diluted earnings per share are computed by dividing net income by the sum of the
weighted-average number of common shares outstanding plus the dilutive effect of
shares issuable through the exercise of stock options (common stock equivalents)
unless their inclusion would be antidilutive.

4.   Investment

     On October 6, 1999 the Company entered into an agreement to acquire 38% of
the shares outstanding of Epsilon Medical, Inc. for $50,000. The Company has
accounted for this investment under the equity method and included the
investment in other assets. The carrying amount of the investment reflects the
Company's share of all losses as of December 31, 1999.

5.   Accounts Receivable

     Contract revenue under cost sharing research and development agreements is
recognized as eligible expenses are incurred. Invoicing of research and
development contracts occurs in accordance with the terms of the contact.
Revenue recognized but unbilled is recorded as unbilled accounts receivable. At
December 31, 1999 unbilled accounts receivable represented approximately 18% of
total accounts receivable.

RESULTS OF OPERATIONS

THREE MONTHS ENDED DECEMBER 31, 1999 AND 1998

Revenues. Total revenues increased to approximately $1,326,000 in the three
months ended December 31, 1999 from $652,000 in the three months ended December
31, 1998. This 103.3% increase was primarily attributable to a 100% increase in
equipment revenue as the Company built and shipped a customized piece of
manufacturing equipment, a 404.1% increase in government contract and grant
revenue as the Company has recently been awarded three phase I and phase II
government contracts and a 80.0% increase in semiconductor revenues. Less than
5% of all revenues were derived from foreign sources.

     The Company's two major customers, the Howmedica/Osteonics Division of
Stryker Corporation and Biomet Incorporated, accounted for 26.3% and .4%
respectively, of revenue for the three months ended December 31, 1999 and 61.1%
and 12.3% in the three months ended December 31, 1998. The Company's government
contract and grant revenue accounted for 24.8% and 10.0% of revenue for the
three months ended December 31, 1999 and 1998, respectively.

     Cost of Product and Contract Research Revenues. Cost of product and
contract research revenue increased to approximately $721,000 from approximately
$410,000 for the three months ended December 31, 1999 and increased as a percent
of revenues to 54.4% from 62.9% in the same periods. This increase in cost is
primarily attributable to the increase in government contract and grant revenue
which are generally low margin, additional personnel and expenses to prepare for
product commercialization, increased depreciation expense and regulatory costs
and expenses associated with implementing quality systems and preparing for
ISO9001 and CE Mark certifications for the I-Plant seed.


                                       8
<PAGE>   9


     Research and Development. Research and development expenses increased to
approximately $290,000 from approximately $83,000 in the three months ended
December 31, 1999, a 249.4% increase, due to product development. The Company
anticipates in future periods its research and development expenses will
continue to increase in total dollars expended as a result of its new product
development plans.

     Selling, General and Administrative. Selling, general and administrative
expenses increased to approximately $598,000 from approximately $264,000 in the
three months ended December 31, 1999. The 126.5% increase in selling, general
and administrative expenses is primarily attributable to increased audit and
legal costs, additional personnel and benefit costs and new investor relations
and shareholders services expenses. The Company anticipates that in future
periods its selling, general and administrative expenses will increase in total
dollars expended as a result of its plans to commercialize new products.

     Other Income and Expense, Net. Other income and expense, net consists
primarily of interest earned on the Company's short-term investments and
interest expense on loans. Other income and expenses increased to approximately
$44,000 in the three months ended December 31, 1999 from approximately ($17,000)
in the three months ended December 31, 1998. This increase primarily reflects
interest income of approximately $70,000 on the Company's short term investments
offset by interest expense $22,000 on the Company's loans and $4,000 of equity
loss associated with the investment in Epsilon Medical, Inc.

SIX MONTHS ENDED DECEMBER 31, 1999 AND 1998

     Revenues. Total revenues increased to approximately $2,200,000 in the six
months ended December 31, 1999 from $1,350,000 in the six months ended December
31, 1998. This 63.0% increase was primarily attributable to a 100% increase in
equipment revenue as the Company built and shipped a customized piece of
manufacturing equipment, a 265.6% increase in government contract and grant
revenue as the Company has recently been awarded three phase I and phase II
government contracts, a 21.5% increase in semiconductor revenues and a 4.2%
increase in orthopedic medical revenues. Less than 5% of all revenues were
derived from foreign sources.

     The Company's two major customers, the Howmedica/Osteonics Division of
Stryker Corporation and Biomet Incorporated, accounted for 33.7% and 5.8%
respectively, of revenue for the six months ended December 31, 1999 and 54.8%
and 7.4% in the six months ended December 31, 1998. The Company's government
contract and grant revenue accounted for 26.9% and 12.0% of revenue for the six
months ended December 31, 1999 and 1998, respectively.

     Cost of Product and Contract Research Revenues. Cost of product and
contract research revenue increased to approximately $1,212,000 from
approximately $789,000 for the six months ended December 31, 1999 and increased
as a percent of revenues to 55.1% from 58.5% in the same periods. This increase
in cost is primarily attributable to the increase in government contract and
grant revenue which are generally low margin, additional personnel and expenses
to prepare for product commercialization, increased depreciation expense and


                                       9
<PAGE>   10


regulatory costs and expenses associated with implementing quality systems and
preparing for ISO9001 and CE Mark certifications.

     Research and Development. Research and development expenses increased to
approximately $478,000 from approximately $158,000 in the six months ended
December 31, 1999, a 202.5% increase, due to product development. The Company
anticipates in future periods its research and development expenses will
continue to increase in total dollars expended as a result of its new product
development plans.

     Selling, General and Administrative. Selling, general and administrative
expenses increased to approximately $1,114,000 from approximately $471,000 in
the six months ended December 31, 1999. The 136.5% increase in selling, general
and administrative expenses is primarily attributable to increased audit and
legal costs, additional personnel and benefit costs and new investor relations
and shareholders services expenses. The Company anticipates that in future
periods its selling, general and administrative expenses will increase in total
dollars expended as a result of its plans to commercialize new products.

     Other Income and Expense, Net. Other income and expense, net consists
primarily of interest earned on the Company's short-term investments and
interest expense on loans. Other income and expenses increased to approximately
$90,000 in the six months ended December 31, 1999 from approximately ($23,000)
in the six months ended December 31, 1998. This increase primarily reflects
interest income of approximately $136,000 on the Company's short term
investments offset by interest expense $42,000 on the Company's loans and $4,000
of expenses associated with the investment in Epsilon Medical, Inc.

     Liquidity and Capital Resources. As of December 31, 1999 the Company had
approximately $4,345,000 in cash in the form of checking and short-term
investments. On December 22, 1999 the Company renegotiated its commercial
banking arrangements. The Company increased its revolving line of credit from a
$300,000 secured line of credit to a $750,000 unsecured line of credit at a
reduced rate of prime, of which $645,000 was available at December 31, 1999.
This line of credit is renewable on December 22, 2000. The Company also has a
term loan and an equipment purchase facility with a commercial bank, under which
approximately $39,000 and $676,000 respectively, were outstanding at December
31, 1999. The Company also has available a new $750,000 equipment purchase
facility of which zero was outstanding at December 31, 1999. Under the new
provisions of its Loan Agreement, the Company is required to maintain compliance
with two financial covenants, minimum levels of net worth and net loss limits.
At June 30, 1999 under the former covenants, the Company's debt service coverage
was less than the required amount. The Company's bank waived its rights under
the Loan Agreement with respect to compliance with this financial covenant for a
period of one year from June 30, 1999. Covenants are measured annually
consistent with the Company's fiscal year end.

     During the six months ending December 31, 1999, operating activities used
cash of approximately $1,371,000 due principally to the payment of operating
expenses and offering costs and an increase in accounts receivable.

     During the six months ending December 31, 1999, investing activities used
cash of


                                       10
<PAGE>   11


approximately $1,034,000. Net cash used by investing activities included
approximately $975,000 in purchases of property and equipment, $50,000 equity
investment in Epsilon Medical and $9,000 of patent fees. The Company intends to
make significant investments over the next several years to support the
development and commercialization of its new products and the expansion of its
manufacturing equipment and capabilities.

     During the six months ended December 31, 1999, financing activities
provided approximately $597,000 in cash. Net cash provided by financing
activities primarily includes approximately $735,000 in proceeds from the
exercise of the underwriter's over-allotment option of 138,000 units, offset by
payments on the Company's line of credit and equipment and term loans. The
Company plans to further increase its expenditures to complete development and
commercialize its new products, to increase its manufacturing capacity, to
ensure compliance with the FDA's Quality System Regulations and to broaden its
sales and marketing capabilities.

December 22, 1999, by and between Implant Sciences Corporation, a Massachusetts

30 Court Street, Boston, Massachusetts 02108 ("Lender").

         WHEREAS, on May 1, 1996, Borrower executed and delivered to Lender a
certain Loan Agreement which established a $100,000 Line of Credit as evidenced
by a certain $100,000 Commercial Promissory Note, and a $300,000 Equipment/Term
Loan as evidenced by a certain $300,000 Commercial Promissory Note, both dated
May 1, 1996, the payment of which was secured, INTER ALIA, by a Security
Agreement also dated May 1, 1996 (the "Security Agreement").

         Said Loan Agreement was amended by a First Amendment to Loan Agreement
dated July 24, 1997 which, inter alia, increased the amount of said Line of
Credit to Three Hundred Thousand ($300,000) Dollars (the "LINE OF CREDIT"), and
reduced said Equipment/Term Loan to One Hundred Five Thousand Five Hundred
Fifty-Five ($105,555) Dollars (the "1997 TERM LOAN") as evidenced by two
Commercial Promissory Notes dated July 24, 1997 (the "LINE OF CREDIT NOTE") and
August 12, 1997 (the "1997 TERM NOTE") respectively, which replaced the Notes
dated May 1, 1996.

         Said Loan Agreement as amended, was further amended by a Second
Amendment to Loan Agreement dated January 16, 1998, which, inter alia, decreased
the 1997 Term Loan to Ninety-Four Thousand Four Hundred Forty-Four and 44/100
($94,444.44) Dollars, and extended a new term loan in the original principal

         WHEREAS, Borrower has requested and Lender has agreed, subject to the
terms and conditions of this Agreement, and in reliance upon the representations
and warranties set forth herein, to establish for Borrower's benefit the
following: (i) to replace the Line of Credit with an unsecured Line of Credit in
the amount of Seven Hundred Fifty-Thousand and 00/100 ($750,000.00) Dollars (the
"REVOLVING LINE OF CREDIT"); and (ii) to extend an equipment/term loan in the
amount of Seven Hundred Fifty-Thousand and 00/100 ($750,000.00) Dollars (the
"1999 TERM LOAN") to the Borrower as set forth below.

         The terms and conditions of this Agreement shall apply to the 1997 Term
Note and the 1998 Equipment Note and the loans evidenced thereby. The terms and
conditions of this Agreement shall supercede those of any prior loan agreement
entered into in connection with the 1997 Term Note and the 1998 Equipment Note
to the extent inconsistent with the terms hereof. The Security Agreement, as
amended shall be deemed to refer to this Agreement and shall remain in full
force and effect. All schedules and exhibits referred to in this Agreement are

could be adversely affected by, and has developed a program to address on a

assessment of Borrower's Year 2000 efforts conducted by any third party.

                  (G) A receiver, liquidator or trustee shall be appointed for

         9.2 ACCELERATION. Upon the occurrence of an Event of Default continuing
beyond any applicable notice and cure periods hereinafter set forth, Lender at
its option may declare all of the Obligations to be immediately due and payable.
Notwithstanding the foregoing, in the case of an Event of Default under Sections
9.1(E), (F), (G), (H) or (I), all of the Obligations, whether arising hereunder
or otherwise, automatically shall become due and payable without presentment,
demand, protest, notice of protest or dishonor, or other notice of any kind, all
of which are hereby expressly waived by Borrower, and without further action of
any kind by Lender.

         9.3 REMEDIES. Upon the occurrence of an Event of Default continuing
beyond any applicable notice and cure periods hereinafter set forth, with or
without accelerating the Obligations under Section 9.1 and without notice,
Lender shall have, in addition to the rights and remedies given it by this
Agreement, the Revolving Note, the 1999 Term Note and the Related Agreements,
all those rights and remedies allowed by all applicable Laws, including the
Uniform Commercial Code as enacted in any jurisdiction in which any Collateral
may be located. Notwithstanding the foregoing, in the case of an Event of
Default under Sections 9.1(E), (F), (G), (H) or (I), all of the Obligations,
whether arising hereunder or otherwise, pursue its rights and remedies as
aforesaid without presentment, demand, protest, notice of protest or dishonor,
or other notice of any kind, all of which are hereby expressly waived by
Borrower, and without further action of any kind by Lender.

         9.4 CURE PERIODS. Borrower shall have ten (10) days after a payment
default under any Note, without notice from Lender, to cure the same and with
respect to all other defaults except those arising under Section 9.1(E), (F),
(G), (H) or (I), Borrower shall have thirty (30) days after written notice from
Lender to cure said other defaults. There shall be no notice and cure with
respect to defaults arising under Section 9.1 (E), (F), (G), (H) or (I).
Notwithstanding the foregoing, Borrower shall have an additional sixty (60) days
to cure non-monetary defaults, but only to the extent the default is not
susceptible of cure within said thirty (30) day period and Borrower is
diligently pursuing same.

         9.5 NOTICE TO ACCOUNT DEBTORS. Lender may, in its sole and absolute
discretion, at any time or times after the occurrence of a Default or an Event
of Default, and without prior notice to Borrower, send a notice to Borrower's
account debtors notifying the account debtors that Borrower's Accounts have been
assigned to Lender, that Lender has a lien thereon and, at Lender's option, that
all payments upon Borrower's Accounts be made directly to Lender.

         9.6 ADDITIONAL RIGHTS OF LENDER. In addition to the foregoing but only
at such time as Lender may exercise those remedies set forth in Section 9.3,
Lender shall have the right: (a) to demand, collect, receive payment of, receipt
for, settle, compromise or adjust, and give discharges and releases



                                       20
<PAGE>   22


in respect of the Accounts or any of them; (b) to commence and prosecute any
suits, actions or proceedings at law or in equity in any court of competent
jurisdiction to collect the Accounts or any of them and to enforce any other
rights in respect thereof or in respect of the goods which have given rise
thereto; (c) to defend any suit, action or proceeding brought against the
Borrower in respect of any Account or the goods which have given rise thereto;
(d) to settle, compromise or adjust any suit, action or proceeding described in
clause (b) or (c) above and, in connection therewith, to give such discharges or
releases as the Lender may deem appropriate; (e) to endorse checks, notes,
drafts, acceptances, money orders, bills of lading, warehouse receipts or other
instruments or documents evidencing or securing the Accounts or any of them; (f)
to receive, open and dispose of all mail addressed to the Borrower and to notify
the post office authorities to change the address of delivery of mail addressed
to the Borrower to such address, care of the Lender, as the Lender may
designate; and (g) generally to sell, assign, transfer, pledge, make any
agreement in respect of or otherwise deal with any Account or the goods or
service which have given rise thereto, as fully and completely as though the
Lender were the absolute owner thereof for all purposes, including contacting
Account Debtors directly for verification or other purposes. The powers
conferred on the Lender by this Agreement are solely to protect the interest of
the Lender and shall not impose any duty upon the Lender to exercise any such
power, and if the Lender shall exercise any such power, it shall be accountable
only for amounts that it actually receives as a result thereof and shall not be
responsible to the Borrower except for gross negligence and willful misconduct.
The Lender shall be under no obligation to take steps necessary to preserve
rights in any other Collateral against prior parties but may do so at its
option. As its option the Lender may discharge any taxes, liens, security
interests or other encumbrances to which any Collateral is at any time subject
and may, upon the failure of the Borrower so to do, purchase insurance on any
Collateral and pay for the repair, maintenance or preservation thereof, and the
Borrower agrees to reimburse the Lender on demand for any payments made or
expenses incurred by the Lender pursuant to the foregoing authorization, and
authorizes the Lender to charge the Borrower for the amount of such payments or
expenses. The Lender may at any time take control of any proceeds of Collateral
to which the Lender is entitled hereunder or under applicable law. In addition,
the Lender may require the Borrower to assemble any tangible personal property
constituting Collateral and make it available to the Lender at a place to be
designated by the Lender and which is reasonably convenient to the Borrower. The
Borrower hereby grants to the Lender a nonexclusive irrevocable license in
connection with the Lender's exercise of its rights hereunder, to use, apply and
affix any trademark, tradename, logo or the like in which the Borrower now or
hereafter has rights, which license may be used upon the occurrence of any of
the Events of Default. The Lender may buy at any public sale, and if the
Collateral is of a type customarily sold on a recognized market or the subject
of widely distributed standard price quotations the Lender may buy at private
sale.

SECTION 10.  MISCELLANEOUS

         10.1 RIGHT OF SET-OFF. Borrower hereby grants to Lender a lien on and a
right of set-off (to be exercised pursuant to the sentence which follows this
sentence) against all monies, deposits, securities and other property and the
proceeds thereof, now or hereafter held or received by, or in transit to Lender
or any entity under the direct or indirect control of Lender from or for
Borrower, whether for safekeeping, pledge, custody, transmission, collection or
otherwise, and all deposits (general or special), balances, sums and credits
with and all of Borrower's claims against Lender at any time existing. Lender
may at any time following and during the continuance of an Event of Default



                                       21
<PAGE>   23


apply the same or any part thereof to the Obligations or any part thereof,
whether or not the Obligations are matured at the time of such application.

         10.2 CUSTODY AND PRESERVATION OF COLLATERAL. Lender shall have no duty
beyond the safe custody thereof as to: (i) the collection or protection of any
Collateral now or hereafter securing any Note or any Obligation or any income
thereon; (ii) the preservation of rights against prior parties; or (iii) the
preservation of any rights pertaining thereto. Lender may exercise its rights
with respect to any Collateral without resorting or regard to any other
Collateral or any other sources of reimbursement for any Obligation.

         10.3 LENDER'S EXPENSES. Except as otherwise provided herein, Borrower
shall, on demand, reimburse Lender for all of Lender's reasonable expenses,
including reasonable fees and expenses of legal counsel for Lender, incurred in
connection with the preparation, administration, amendment, modification,
delivery or enforcement of this Agreement, the 1999 Term Note, the Revolving
Note and/or the Related Agreements or the collection or attempted collection of
the 1999 Term Note, the Revolving Note, including any such reasonable fees and
expenses related to any federal bankruptcy proceeding and whether incurred prior
or subsequent to any federal bankruptcy proceeding.

         10.4 ENFORCEMENT AND WAIVER BY LENDER. Lender shall have the right at
all times to enforce the provisions of this Agreement, the 1999 Term Note, the
Revolving Note and the Related Agreements in strict accordance with the terms
hereof and thereof, notwithstanding any conduct or custom on the part of Lender
in refraining from so doing at any time or times. Lender's failure or delay at
any time or times to enforce its rights or remedies under such provisions
strictly in accordance with the same shall not be construed as having created a
custom in any way or manner contrary to the specific provisions of this
Agreement or as having in any way or manner modified or waived the same. No
waiver of any provision of, or any of Lender's rights under, this Agreement, any
Note, any Related Agreement or any other document or agreement now or hereafter
relating to any of the Obligations and/or the Collateral, and no consent to any
departure by any Person therefrom, shall be effective unless such waiver or
consent is in writing and signed by an authorized officer of Lender, and then
such waiver or consent shall be effective only in the specific instance and for
the specific purpose for which such waiver or consent is given. All of Lender's
rights and remedies under this Agreement, any Note and/or any Related Agreement
are cumulative and concurrent, and may be exercised singularly or concurrently
and are not exclusive or in derogation of any other rights or remedies provided
by Law or otherwise. Lender's exercise or partial exercise of one right or
remedy shall not be deemed a waiver or release of and shall not preclude the
further exercise of such right or remedy or any other right or remedy.

         10.5 WAIVERS AND RELEASE. To the maximum extent permitted by applicable
Laws, Borrower:

                  (A) ACKNOWLEDGES THAT EACH OF THE TRANSACTIONS CONTEMPLATED BY
THIS AGREEMENT, THE REVOLVING NOTE, THE 1999 TERM NOTE AND EACH OF THE RELATED
AGREEMENTS IS A COMMERCIAL TRANSACTION, AND HEREBY EXPRESSLY AND IRREVOCABLY
WAIVES TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW ITS RIGHTS TO NOTICE

         10.9 BINDING EFFECT, ASSIGNMENT AND ENTIRE AGREEMENT. This Agreement,
each Note and each Related Agreement to which it is a party shall inure to the
benefit of, and shall be binding upon, each of Borrower and Lender and their
respective successors, permitted transferees and permitted assigns. Borrower
shall not assign any of its rights or delegate any of its Obligations hereunder

consent, and any such assignment in contravention of this Section 10.9 shall be
null and void. This Agreement, the 1999 Term Note, the Revolving Note, the
Related Agreements and the documents executed and delivered pursuant hereto and
thereto, constitute the entire agreement between the parties with respect to the
transactions contemplated by this Agreement, and supersede all prior written or
oral understandings, agreements and commitments with respect to the subject
matter hereof and/or thereof, all of which prior understandings, agreements and
commitments are merged into this Agreement, the Revolving Note, the 1999 Term
Note and the Related Agreements. Except as specifically set forth in any Related
Agreement, no amendment, modification or termination of any provision of this
Agreement, any Note, any Related Agreement or any document or agreement now or
hereafter relating to any of the Obligations and/or the Collateral shall be
effective unless the same shall be contained in a writing signed by the parties
to this Agreement and any other Persons who are parties to such Note, Related
Agreement or other document or agreement. No notice to or demand on Borrower in
any case shall entitle Borrower to any other or further notice or demand in
similar or other circumstances.

         10.10 PAYMENT DATES. Whenever any payment to be made hereunder or under
a Note shall be stated to be due on a calendar day other than a Banking Day,

inspect Borrower's premises and books and records.

         10.12 SEVERABILITY. If any provision of this Agreement, any Note or any
Related Agreement shall be held invalid under any applicable Law, such
invalidity shall not affect any other provision of this Agreement, such Note or
such Related Agreement, as applicable, that can be given effect without the
invalid provision, and, to this end, the provisions of each of this Agreement,
each Note and each Related Document are severable.

$750,000.00                                                December 22, 1999
                                                           Boston, Massachusetts

         For value received, Implant Sciences Corporation (the "Borrower")
promises to pay to the order of USTrust ("Lender") at the office of Lender
located at 50 Court Street, Boston, MA 02108, or such other place as the holder
hereof shall designate, ON DEMAND, SEVEN HUNDRED FIFTY THOUSAND AND 00/100
($750,000) DOLLARS or, if less, the aggregate unpaid principal amount of all
loans made by the Lender to the Borrower pursuant to this Note. The Borrower
further promises to pay the order of the Lender interest only monthly in arrears
commencing January 22, 2000 and thereafter on the 22nd day of each calendar
month at a fluctuating interest rate per annum equal to Lender's Base Rate.
"Base Rate" shall mean the rate of interest announced by Lender at its principal
office in Boston from time to time as its "Base Rate." The Base Rate is a
reference rate and does not necessarily represent the lowest or best rate being
charged to any customer. Interest shall be calculated on the basis of actual
days elapsed and a 360-day year. At any time that Borrower is in default
hereunder or under any obligation to the Lender or in the event this Note is not
paid in full ON DEMAND, interest on unpaid balances shall thereafter be payable
at a fluctuating interest rate per annum equal to four (4%) percent above the
Interest Rate in effect from time to time. Borrower shall pay to Lender a late
charge in the amount of five (5%) percent of each periodic payment due hereunder
which is more than ten (10) days in arrears to offset the additional expenses
involved in processing delinquent payments. To the extent a payment due date
does not fall on a regular business day then the due date shall be deemed to be
the first business day which follows said payment date.

         At Borrower's option, the entire principal amount shall bear interest
at a rate equal to Libor plus Two Hundred Fifty (250) Basis Points per annum
(the "LIBOR Rate"). The Libor Rate shall be set for periods of thirty (30),
sixty (60), ninety (90) or one hundred and eighty (180) days (the "Designated
Libor Rate Period"). Libor (the "London Interbank Offered Rate") means the rate
per annum at which deposits in U.S. Dollars are offered to the Lender by
first-class banks in the London Interbank Market at approximately 11:00 a.m.
(London time) no more than two (2) Business Days prior to the first day of the
applicable Designated Libor Rate Period and with a maturity comparable to such
Designated Libor Rate Period. Each Designated Libor Rate Period shall end on the
last day of the particular Designated Libor Rate Period unless the last day is
not a regular banking day in which event the Designated Libor Rate Period shall
end on the next succeeding day which is a regular banking day and any Designated
Libor Rate Period that would otherwise extend beyond the maturity date of this
Note shall end on the maturity date of this Note. The Base Rate based interest
rate shall be in effect whenever said Libor Rate based option has not been
elected by the Borrower, but only with respect to principal not earning interest
pursuant to the Fixed Rate Election as defined below. If at any time the Libor
Rate based option becomes unavailable for any reason then the Libor Rate based
option set forth above shall terminate.

         Borrower shall have the right to make full or partial prepayments of
principal at any time. Prepayments of principal on which interest is accruing at
an interest rate based on the Base Rate may be made from time to time without a
fee or premium. In the event Borrower prepays Principal earning



<PAGE>   34


interest at a Libor based rate during a Designated Libor Rate Period whether
voluntarily or as a result of acceleration or otherwise, or in the event
Borrower elects a Libor Rate based interest rate and then cancels said election,
then Borrower shall pay a prepayment fee and/or a cancellation fee as the case
may be (the "Prepayment Fee") equal to the following: the then current rate for
United States Treasury securities (bills on a discounted basis shall be
converted to a bond equivalent) with a maturity date closest to the maturity
date of the Designated Libor Rate Period as to which the prepayment is made,
shall be subtracted from the "cost of funds" component of the Libor Rate in
effect at the time of prepayment. If the result is zero or a negative number,
there shall be no Prepayment Fee. If the result is a positive number, then the
resulting percentage shall be multiplied by the amount of the principal balance
being prepaid. The resulting amount shall be divided by 360 and multiplied by
the number of days remaining in the Designated Libor Rate Period as to which
prepayment is made. Said amount shall be reduced to present value calculated by
using the number of days remaining in the Designated Libor Rate Period using the
above-referenced United States Treasury security rate and the number of days
remaining in the term so chosen as to which the prepayment is made. The
resulting amount shall be the Prepayment Fee due to Lender upon prepayment of
Libor Principal. To the extent Borrower prepays Principal during the Fixed Rate
Election period, whether voluntarily or as a result of acceleration or otherwise
then Borrower shall pay a Prepayment Fee as calculated by the Lender in its
discretion.

         If at any time the aggregate outstanding balance hereunder shall exceed
SEVEN HUNDRED FIFTY THOUSAND and 00/100 DOLLARS ($750,000), the Borrower shall
immediately repay this Note in an amount equal to such excess.

         Borrower shall maintain a zero (0) balance hereunder for thirty (30)
consecutive days during each loan year.

         Any deposits or other sums at any time credited by or due from the
holder to the Borrower and any securities or other property of the Borrower or
any such endorser at any time in the possession of the holder may at all times
be held and treated as collateral for the payment of this Note and any and all
other liabilities (direct or indirect, absolute or contingent, sole, joint or
several, secured or unsecured, due or to become due, now existing or hereafter
arising) of the Borrower to the holder. Regardless of the adequacy of
collateral, the holder may apply or set off such deposits or other sums against
such liabilities upon an event of default continuing beyond any applicable
notice and cure provisions in the case of the Borrower, but only with respect to
matured liabilities in the case of endorser.

         The Borrower hereby waives the right to a jury trial, presentment,
demand, notice, protest and all other demands and notices in connection with the
delivery, acceptance, performance, default or enforcement hereof and consents
that no indulgence, and no substitution, release or surrender of collateral, and
no discharge or release of any other party primarily or secondarily liable
hereon, shall discharge or otherwise affect the liability of the Borrower or any
such endorser. No delay or omission on the part of the holder in exercising any
right hereunder shall operate as a waiver of such right or of any other right
hereunder, and a waiver of any such right on any one occasion shall not be
construed as a bar to or waiver of any such right on any future occasion.

         This Note is secured by any collateral at any time granted to Lender to
secure any obligations of any maker hereof.

         The Lender may at any time pledge all or any portion of its rights
under the loan documents entered into in connection herewith and any portion of
this Note to any of the twelve (12) Federal Reserve Banks organized under
Section 4 of the Federal Reserve Act, 12 U.S.C. Section 341.

         Upon receipt of an affidavit, including an indemnification reasonably
satisfactory to Maker, of an officer of Lender as to the loss, theft,
destruction or mutilation of this Note or any other security document which is
not of public record, and, in the case of any such loss, theft, destruction or
mutilation, upon surrender and cancellation of such Note or other security
documents, Borrower will issue, in lieu thereof, a replacement Note or other
security document in the same principal amount hereof and otherwise of like
tenor.

         The Borrower agrees to pay on demand all reasonable costs and expenses
(including legal costs and reasonable attorney's fees) incurred or paid by the
holder in enforcing this note on default.

         The Note incorporates the terms and conditions set forth in the Loan
Agreement, which terms and conditions are incorporated by reference herein,
including without limitation, Borrower's warranties, covenants and negative
covenants contained therein.

         This Note shall take effect as a sealed instrument and shall be
governed by the laws of the Commonwealth of Massachusetts.
