                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                                  (UNAUDITED)



Note 1.  Basis of Presentation

         The financial information included herein is unaudited, however, the
information reflects all adjustments (consisting solely of normal recurring
adjustments) that are, in the opinion of management, necessary for a fair
presentation of the financial position, results of operations and cash flows for
the interim periods presented. These financial statements should be read in
conjunction with the financial statements and notes thereto and management's
discussion and analysis of financial condition and results of operations
included in the Company's Registration Statement on Form S-1 dated November 8,
1996.

         The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

         The results of operations for the periods ended September 29, 1996 are
not necessarily indicative of the operating results to be expected for the full
year.

         The condensed balance sheet as of December 31, 1995 has been derived
from the audited financial statements at that date.


Note 2.  Income Taxes

         The Company's operations prior to the transfer discussed in Note 4,
were included in the income tax returns of Lau Acquisition Corp. d/b/a Lau
Technologies, an S corporation. Income tax allocations for such periods have
been calculated as if the Company were filing separate income tax returns taking
into consideration that operating losses and tax credits have been utilized by
the shareholders of Lau Technologies.


Note 3.  Net Income (Loss) Per Share

         Net income (loss) per share is computed based on the weighted average
number of 6,225,000 common and common equivalent shares outstanding during the
period. This number is comprised of 5,680,000 shares of common stock issued in
connection with the transfer discussed in Note 4 and 545,000 shares related to
common equivalents. Pursuant to certain requirements of the Securities and
Exchange Commission, common and common equivalent shares issued during the 12
months prior to the initial public offering date (using the treasury stock
method) have been included in the calculation of weighted average shares for all
periods presented.

Note 4.  Subsequent Events

         On November 22, 1996, the Company entered into a revolving credit
agreement with a commercial bank. The agreement provides for unsecured
borrowings of up to $10.0 million through June 1998 at prime rate or other
LIBOR-based options and requires the Company to maintain certain financial
ratios and minimum levels of earnings and tangible net worth.

         On November 6, 1996, Lau Technologies completed the transfer of
substantially all of the assets, liabilities and operations of its Viisage
Technology Division to the Company in exchange for 5,680,000 shares of the
Company's common stock. After the completion of the initial public offering
discussed below, the Company is a 64% owned subsidiary of Lau Technologies.

         In November 1996, the Company completed an initial public offering of
2,875,000 shares of its common stock, of which 2,375,000 shares (including the
over-allotment option) were sold by the Company and 500,000 shares were sold by
the selling stockholder. The offering price was $10.50 per share and the net
proceeds to the Company were approximately $22,355,000, net of underwriting
discounts and other estimated offering expenses. The Company used approximately
$8,800,000 of the proceeds to repay long-term borrowings.  The remainder of the
net proceeds are expected to be used for working capital and other general
corporate purposes.


Note 5.  Pro Forma Condensed Balance Sheet

         The pro forma condensed balance sheet as of September 29, 1996 reflects
(i) the transfer, initial public offering and repayment of long-term borrowings
discussed in Note 4 and (ii) the estimated net deferred income tax liability
that will be recorded by the Company in connection with the aforementioned
transfer and change in tax status.

Item 2 - Management's Discussion and Analysis of Financial Condition and Results
of Operations

      The following discussion and analysis should be read in conjunction with
the financial statements and notes thereto and risk factors contained in the
Company's Form S-1 Registration Statement dated November 8, 1996.

      This Form 10-Q contains forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934. The Company's actual results could differ materially from
those discussed herein. Factors that might cause or contribute to such
differences are discussed in the section entitled "Certain Factors that may
Affect Future Results" below.

Overview
- --------

      The Company designs, sells and implements turnkey digital identification
systems intended to deter fraud and to reduce customers' identification program
costs. These systems capture facial images, demographic information and other
biological identifiers, produce identification cards, and create relational
databases containing this information. Using its systems integration and
software design capabilities, the Company is able to combine its proprietary
software and hardware products with commercially available components and
customers' existing systems, creating a complete customized solution. In
addition, the Company is developing proprietary facial recognition software
designed to identify individuals in a large database of faces on a real-time
basis.

      Viisage provides systems and services principally under contracts that
have five-year terms and provide for several annual renewals after the initial
contract term. Contracts generally provide for a fixed price for the system
and/or for each card produced. Contract prices vary depending on, among other
things, design and integration complexities, the nature and number of
workstations and sites, the projected number of cards to be produced, the level
of post-installation support and the competitive environment. Substantially all
of the Company's revenues are currently derived from public sector customers and
contractors to such customers. The Company believes for the foreseeable future
that it will continue to derive a significant portion of its revenues from a
limited number of large contracts. For the nine months ended September 29, 1996,
three customers each accounted for more than 10% of the Company's revenues and
an aggregate of 65% of revenues for the period.

      The Company's results of operations are significantly affected by, among
other things, the timing of award and performance on contracts. As a result, the
Company's revenues and income may fluctuate from quarter to quarter, and
comparisons over longer periods of time may be more meaningful. The Company's
results of operations are not seasonal since contracts are awarded and performed
throughout the year.

Results of Operations
- ---------------------

Revenues. Revenues are derived principally from systems implementation, card
production and related services under multi-year contracts. Revenues increased
131% to $6.3 million for the quarter ended September 29, 1996 from $2.7 million
for the comparable period in 1995. For the nine months ended September 29, 1996
revenues increased 124% to $18.1 million from $8.1 million for the same period
in 1995. These increases were due to an increase in the number of contracts
being performed during the 1996 periods.

Project Costs and Margin. Project costs consist primarily of hardware,
consumables (printer ribbons, cards, holographic overlays, etc.), system design,
software development and implementation labor, maintenance and overhead. As a
percentage of revenues, project costs decreased to 75% and 79% for the quarter
and nine months ended September 29, 1996, respectively, from 92% for the
comparable periods in 1995. These decreases reflect cost savings on design,
development and implementation activities resulting from the Company's increased
experience with and resources for digital identification solutions. Project
margin increased 592% to $1.5 million (25% of revenues) for the quarter ended

                                       6
<PAGE>
 
September 29, 1996 from $223,000 (8% of revenues) for the comparable period in
1995. For the nine months ended September 29, 1996 project margin increased 482%
to $3.8 million (21% of revenues) from $646,000 (8% of revenues) for the same
period in 1995. These increases reflect the increases in revenues and cost
savings discussed above. The Company believes it could experience further
improvements in project margin from project cost savings and improved pricing.
However, there can be no assurance that such improvements will be achieved.

Sales and Marketing. Sales and marketing expenses consist primarily of
compensation and professional service fees for marketing, bid and proposal and
customer support activities. Sales and marketing expenses increased 75% to
$500,000 for the quarter ended September 29, 1996 from $285,000 for the
comparable period in 1995. For the nine months ended September 29, 1996 sales
and marketing expenses increased 72% to $1.2 million from $716,000 for the same
period in 1995. These increases principally reflect an increase in proposal
activity and the addition of marketing personnel during 1996. As a percentage of
revenues, sales and marketing expenses decreased to 8% and 7% for the 1996
periods from 11% and 9% for the 1995 periods due to revenues increasing at a
greater rate than such expenses during the 1996 periods. The Company anticipates
that it will continue to make significant expenditures for sales and marketing
as it adds resources and initiates operations in additional markets.

Research and Development. Research and development expenses consist principally
of compensation, outside services and materials utilized for product and
software development activities that are not related to specific projects.
Research and development expenses decreased 64% to $72,000 for the quarter ended
September 29, 1996 from $198,000 for the comparable period in 1995, and
decreased as a percentage of revenues to 1% for 1996 from 7% for 1995. For the
nine months ended September 29, 1996 research and development expenses decreased
75% to $200,000 from $795,000 for the same period in 1995, and decreased as a
percentage of revenues to 1% for 1996 from 10% for 1995. These decreases reflect
the completion in 1995 of proprietary software to support all industry standard
computing environments and proprietary hardware products for the Company's card-
based systems and the increases in revenues in the 1996 periods. The Company
believes that these software and hardware products will support its card-based
identification systems offerings for the foreseeable future. Expenditures for
1996 relate primarily to the Company's facial recognition products and do not
reflect the benefits to the Company under license arrangements from the research
and development efforts of Lau and the Massachusetts Institute of Technology for
projects that are not related to Viisage.

General and Administrative. General and administrative expenses consist
principally of compensation for executive management, finance and administrative
personnel and outside professional fees. General and administrative expenses
increased 54% to $463,000 for the quarter ended September 29, 1996 from $300,000
for the comparable period in 1995. For the nine months ended September 29, 1996
general and administrative expenses increased 66% to $1.4 million from $813,000
for the same period in 1995. These increases are due primarily to the addition
of management personnel during the fourth quarter of 1995 and increased
management activities related to the growth in the Company's business. As a
percentage of revenues, general and administrative expenses decreased to 7% for
the 1996 periods from 11% and 10% for the 1995 periods due to revenues
increasing at a greater rate than such expenses in the 1996 periods.

Interest Expense. The increases in interest expense to $211,000 for the quarter
ended September 29, 1996 from $188,000 for the comparable period in 1995 and to
$598,000 for the nine months ended September 29, 1996 from $321,000 for the 1995
period principally reflect the increase in the level of borrowings during the
1996 periods.

Income Taxes. The Company's operations prior to the transfer discussed in Note 4
of Notes to Condensed Financial Statements were included in the income tax
returns of Lau Technologies, an S corporation. After the transfer, the Company
will be subject to federal and state income taxation at the corporate level and
will be required to file its own separate tax returns. The Company anticipates
that it will recognize a non-recurring charge relating to a net deferred tax
liability of approximately $100,000 arising from the change in its tax status in
the fourth quarter when the transfer occurred.

                                       7

Liquidity and Capital Resources
- -------------------------------

      At September 29, 1996, working capital was $8.4 million compared to $7.4
million at December 31, 1995. The increase in working capital was due primarily
to increases in accounts receivable and costs and estimated earnings in excess
of billings, net of increases in accounts payable and accrued expenses.

      For the nine months ended September 29, 1996, operations and investing
activities utilized cash of approximately $388,000 and $2.4 million,
respectively, principally to fund the working capital increases discussed above
and the increase in project assets. Financing was provided by borrowings under
line of credit and project lease financing facilities and parent company
advances.

      As discussed more fully in Note 4 of Notes to Condensed Financial
Statements, in November 1996 the Company completed an initial public offering of
its common stock and received net proceeds of approximately $22,355,000. The
Company used $8.8 million of the proceeds to repay long-term borrowings. On a
pro forma basis, at September 29, 1996 working capital was $22.0 million,
including cash and cash equivalents of $13.6 million.

      The Company has a revolving line of credit with a commercial bank that
provides for unsecured borrowings of up to $10.0 million through June 1998 at
prime rate or other LIBOR-based options. This agreement requires the Company to
maintain certain financial ratios and minimum levels of earnings and tangible
net worth. The Company also has a system project lease financing arrangement
with a commercial leasing organization providing for project financing of up to
$15.0 million. Pursuant to this arrangement, the lessor will purchase certain of
the Company's digital identification systems and lease them back to Viisage for
deployment with identified and contracted customers approved by the lessor. The
lessor will retain title to systems and will have an assignment of Viisage's
rights under the related customer contracts, including rights to use the
software and technology underlying the related systems. Under this arrangement,
the lessor will bear the credit risk associated with payments by Viisage's
customers, but Viisage will bear performance and appropriation risk and will
generally be required to repurchase a system in the event of a termination by a
customer for any reason except credit default.  These project lease arrangements
are accounted for as capital leases.

      The Company believes that the net proceeds from its initial public
offering, together with cash flow from operations, available borrowings and
project leasing, will be sufficient to meet the Company's working capital and
capital expenditure needs for at least the next 12 months. There can be no
assurance, however, that additional financing, if needed, will be available on
favorable terms or at all. If the Company is unable to obtain additional
capital, if needed, on acceptable terms the Company may be unable to take full
advantage of future opportunities or respond to competitive pressures, which
could adversely affect the Company's business, financial condition and results
of operations.

Certain Factors That May Affect Future Results
- ----------------------------------------------

      This Form 10-Q contains forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934. The Company's actual results could differ materially from
those discussed herein. Certain factors that could cause or contribute to such
differences include, among other things, potential fluctuations in quarterly
results, the size and timing of award and performance on contracts, dependence
on large contracts and a limited number of customers, lengthy sales and
implementation cycles, changes in management estimates incident to accounting
for contracts, availability and cost of key components, market acceptance of new
or enhanced products and services, proprietary technology and changing
technology, competitive conditions, system performance, management of growth,
dependence on key personnel and general economic and political conditions and
other factors affecting spending by customers.  Please also refer to the factors
set forth in the Company's Registration Statement on Form S-1 dated November 8,
1996 under the caption "Risk Factors" which are incorporated herein by
reference.

PART II - OTHER INFORMATION

Item 1 - Legal Proceedings

          On September 23, 1996, three minority shareholders of Lau Technologies
filed suit against Lau Technologies, the Company and others in Superior Court in
Berkshire County, Massachusetts, alleging that certain defendants breached the
fiduciary duty owed the plaintiffs as shareholders of Lau Technologies.  The
plaintiffs requested, among other things, an injunction to delay the Company's
public offering in an effort to obtain a direct, rather than an indirect,
ownership interest in the Company.  On October 4, 1996, the Superior Court
denied plaintiffs' request for such relief, although plaintiffs' claims for
unspecified money damages remain pending.  Lau Technologies has agreed to
indemnify and hold the Company harmless for any liabilities incurred by the
Company as a result of judgments, settlements or litigation expenses arising out
of this suit. Accordingly, the Company does not believe that the resolution of
this matter would have a material adverse effect on its business, financial
condition or results of operations.

                             DESCRIPTION OF CREDIT
                            ----------------------

     2.1  Revolving Credit Loans.
          ---------------------- 

          (a) Upon the terms and subject to the conditions of this Agreement,
and in reliance upon the representations, warranties and covenants of the
Borrower herein, the Lender agrees to make revolving credit loans (the
                                                                      
"Revolving Credit Loans") to the Borrower at the Borrower's request, or as
- -----------------------                                                   
provided in Section 2.3, from time to time from and after the Closing Date and
prior to the Maturity Date, provided that the Total Outstandings (after giving
                            --------                                          
effect to all requested Loans and Letters of Credit) shall not at any time
exceed the Maximum Amount.  Subject to the terms and conditions of this
Agreement, the Borrower may borrow, repay, prepay and reborrow amounts, up to
the limits imposed by this Section 2.1, from time to time between the Closing
Date and the Maturity Date upon request given to the Lender pursuant to Section
2.3. Each request for a Revolving Credit Loan or Letter of Credit hereunder
shall constitute a representation and warranty by the Borrower that the
conditions set forth in Sections 3.1 and 3.2 have been satisfied as of the date
of such request or the date any overdraft advance that is a Prime Rate Loan made
pursuant to the Lender's Liquidity Management Control System.

          (b) No LIBOR Loan shall be requested or made for less than $100,000 in
principal amount and in integral multiples of $100,000.  No more than five LIBOR
Loans may be outstanding at any time.

          (c) Upon the terms and subject to the conditions of this Agreement,
the Borrower may convert all or any part (in integral multiples of $100,000) of
any outstanding Loan into a Loan of another Type on any Business Day (which, in
the case of a conversion of an outstanding LIBOR Loan shall be the last day of
the Interest Period applicable to such LIBOR Loan). The Borrower shall give the
Lender prior notice of each such conversion (which notice shall be effective
upon receipt) in accordance with Section 2.3.

          (d) The Commitment shall automatically terminate at 5:00 p.m. Boston
time on the Maturity Date.  Subject to the provisions of Section 2.7 regarding
mandatory payments, the Borrower shall have the right at any time and from time
to time upon five (5) Business Days' prior written notice to the Lender to
reduce the Maximum Amount or to terminate entirely the Lender's Commitment
hereunder.  No such reduction or termination of any Commitment may be
reinstated. If, as a result of any such reduction, the Maximum Drawing Amount at
the time would exceed the Maximum Amount or the maximum amount of Letters of
Credit permitted to be outstanding under Sections 2.1(a) and 2A.1(a) hereof, the
Borrower shall, as a condition precedent to any such reduction, deposit with and
pledge to the Lender cash or cash equivalents in an amount equal to 100% of such
excess.  If any Letters of Credit would remain outstanding after the effective
date of any such termination, in addition to satisfaction of all other
applicable terms and conditions of this Agreement, the Borrower shall deposit
with and pledge to the Lender cash or cash equivalents in an amount equal to
100% of the Maximum Drawing Amount at the effective date of such termination.
Amounts so held by SSB by reason of this Section 2.1(d) shall be held in
interest-bearing accounts and shall be applied, together with any interest
accrued thereon, in satisfaction of Reimbursement Obligations or, when and if
such Reimbursement Obligations have been satisfied in full by the Borrower or by
such application by SSB, any excess of such amounts so held shall be refunded by
SSB to the Borrower.

     2.2  The Credit Note.  The Revolving Credit Loans shall be evidenced by a
          ---------------                                                     
promissory note of the Borrower in substantially the form of Exhibit A hereto
                                                             ---------       
(the "Credit Note"), dated as of the Closing Date.  The Borrower irrevocably
      -----------                                                           
authorizes the Lender to make or cause to be made, at or about the time of the
Drawdown Date of any Revolving Credit Loan or at the time of receipt of any

                                      -10-
<PAGE>
 
payment of principal on the Credit Note, an appropriate notation on the Note
Record reflecting (as the case may be) the making of such Revolving Credit Loan
or the receipt of such payment.  The outstanding amount of the Revolving Credit
Loans set forth on the Note Record shall be prima facie evidence of the
                                            -----------                
principal amount thereof owing and unpaid to the Lender, but the failure to
record, or any error in so recording, any such amount on the Lender's Note
Record shall not limit or otherwise affect the obligations of the Borrower
hereunder or under any Credit Note to make payments of principal of or interest
on any Credit Note when due.

     2.3  Notice and Manner of Borrowing or Conversion of Loans.
          ----------------------------------------------------- 

          (a) Whenever the Borrower desires to obtain or continue a Loan
hereunder or convert an outstanding Loan into a Loan of another Type, the
Borrower shall give SSB a written Notice of Borrowing or Conversion (or a
telephonic notice promptly confirmed by a written Notice of Borrowing or
Conversion), which Notice shall be irrevocable and which must be received no
later than 11:00 a.m. Boston time on the date (i) one Business Day before the
day on which the requested Loan is to be made as or converted to a Prime Rate
Loan, and (ii) three Business Days before the day on which the requested Loan is
to be made or continued as or converted to a LIBOR Loan; provided, however, that
                                                         --------  -------      
no such prior notice shall be required for Prime Rate Loans that are overdraft
advances made pursuant to the Lender's Liquidity Management Control System.
Such Notice of Borrowing or Conversion shall specify (i) the effective date and
amount of each Loan or portion thereof requested to be made, continued or
converted, subject to the limitations set forth in Section 2.1, (ii) the
interest rate option requested to be applicable thereto, and (iii) the duration
of the applicable Interest Period, if any (subject to the provisions of the
definition of the term "Interest Period").  If such Notice fails to specify the
interest rate option to be applicable to the requested Loan, then the Borrower
shall be deemed to have requested a Prime Rate Loan. If the written confirmation
of any telephonic notification differs in any material respect from the action
taken by SSB, the records of SSB shall control absent manifest error.

          (b) Subject to the provisions of the definition of the term "Interest
Period" herein, the duration of each Interest Period for a LIBOR Loan shall be
as specified in the applicable Notice of Borrowing or Conversion.  If no
Interest Period is specified in a Notice of Borrowing or Conversion with respect
to a requested LIBOR Loan, then the Borrower shall be deemed to have selected an
Interest Period of one month's duration.  If SSB receives a Notice of Borrowing
or Conversion after the time specified in subsection (a) above, such Notice
shall not be effective.  If SSB does not receive an effective Notice of
Borrowing or Conversion with respect to an outstanding LIBOR Loan, or if, when
such Notice must be given prior to the end of the Interest Period applicable to
such outstanding Loan, the Borrower shall have failed to satisfy any of the
conditions hereof, the Borrower shall be deemed to have elected to convert such
outstanding Loan in whole into a Prime Rate Loan on the last day of the then
current Interest Period with respect thereto.

     2.4  Interest Rates and Payments of Interest.
          --------------------------------------- 

          (a) Each Loan which is a Prime Rate Loan shall bear interest on the
outstanding principal amount thereof at a rate per annum equal to the Prime
Rate, which rate shall change contemporaneously with any change in the Prime
Rate.   Such interest shall be payable monthly in arrears on the first Business
Day of each month, commencing on the first Business Day of the month immediately
following the month in which the Closing Date occurs.

          (b) Each Loan which is a LIBOR Loan shall bear interest on the
outstanding principal amount thereof, for each Interest Period applicable
thereto, at a rate per annum equal to the LIBOR Rate plus the Applicable Margin.
Such interest shall be payable for such Interest Period on the last day thereof
and, if such Interest Period is longer than three months, at intervals of three
months after the first day thereof.

                                      -11-
<PAGE>
 
          (c) If an Event of Default shall occur, then at the option of the
Lender the unpaid balance of Loans shall bear interest, to the extent permitted
by law, compounded daily at an interest rate equal to 2% per annum above the
interest rate applicable to each such Loan in effect on the day such Event of
Default occurs, until such Event of Default is cured or waived.

          (d) So long as the Lender shall be required under regulations of the
Board of Governors of the Federal Reserve System (or any other banking
authority, domestic or foreign, to which the Lender is subject) to maintain
reserves with respect to liabilities or assets consisting of or including
"Eurocurrency Liabilities" (as defined in regulations issued from time to time
by such Board of Governors), the Borrower shall pay to the Lender additional
interest on the unpaid principal amount of each LIBOR Loan from the date such
Loan is made until such principal amount is paid in full, at an interest rate
per annum equal at all times to the remainder (rounded upwards, if necessary, to
the next higher 1/100 of 1%) obtained by subtracting (i) the LIBOR Rate for the
Interest Period for such LIBOR Loan from (ii) the rate obtained by dividing such
LIBOR Rate by a percentage equal to 100% minus the LIBOR Reserve Percentage for
such Interest Period.  Such additional interest shall be payable on each date on
which interest is payable on such LIBOR Loan. Notwithstanding anything in
Section 2.8 to the contrary, in the event that such additional interest causes
the effective interest rate of any LIBOR Loan to exceed the Prime Rate at such
time, the Borrower may prepay such LIBOR Loan, or convert such LIBOR Loan to a
Prime Rate Loan, without premium or penalty.

     2.5  Fees.
          ---- 

          (a) The Borrower shall pay to the Lender a commitment fee (the
"Commitment Fee"), computed on a daily basis and payable quarterly in arrears on
the first Business Day of each February, May, August and November, commencing
February 1997, equal to one-quarter of one percent (0.25%) per annum of the
excess of (i) the Maximum Amount at the time over (ii) the Total Outstandings
from time to time.

          (b) The Borrower shall pay to the Lender a fee (the "Letter of Credit
                                                               ----------------
Fee") based upon a per annum percentage of the Maximum Drawing Amount of each
- ---                                                                          
Letter of Credit as agreed upon from time to time, payable in advance on the
date of issuance or renewal of the applicable Letter of Credit, provided that at
the option of the Lender the Letter of Credit Fees payable during the
continuance of any Event of Default shall be equal to one percent (1%) per annum
in excess of the Letter of Credit Fee in effect at such time.

          (c) The Borrower shall pay to the Lender such other charges imposed by
the Lender on the Borrower as the parties may agree for related banking and
custodial services as are customarily imposed by the Lender on its customers
generally.

          (d) The Borrower authorizes the Lender to charge to the Note Record or
to the Borrower's operating account with the Lender the interest, fees, charges,
taxes and expenses provided for in this Agreement, the other Loan Documents or
any other document executed or delivered in connection herewith or therewith.

     2.6  Payments and Prepayments of the Loans.
          ------------------------------------- 

          (a) On the Maturity Date, the Borrower shall pay in full the unpaid
principal balance of the Revolving Credit Loans, together with all unpaid
interest thereon and all fees and other amounts due with respect thereto.
Revolving Credit Loans that are LIBOR Loans may be paid, without premium or
penalty, on the last day of any Interest Period applicable thereto, upon three
Business Days' notice.  Revolving Credit Loans that are Prime Rate Loans may be
prepaid at any time, without premium or penalty, upon one Business Day's notice;
provided, however, that no such prior notice shall be required for prepayments
of overdraft advances that are Prime Rate Loans

                                      -12-
<PAGE>
 
made pursuant to the Lender's Liquidity Management Control System. Any such
notice of prepayment shall be irrevocable. Prepayments of Revolving Credit Loans
may be reborrowed to the extent provided in Section 2.1.

          (b) If at any time the Total Outstandings exceed the Maximum Amount,
the Borrower shall immediately pay the amount of any such excess to the Lender
for application to the Loans.

     2.7  Method of Payment.  All payments by the Borrower hereunder and under
          -----------------                                                   
any of the other Loan Documents shall be made without set-off or counterclaim
and free and clear of and without deduction for any taxes, levies, imposts,
duties, charges, fees, deductions, withholdings, compulsory loans, restrictions
or conditions of any nature now or hereafter imposed or levied by any
jurisdiction or any political subdivision thereof or taxing or other authority
therein unless the Borrower is compelled by law to make such deduction or
withholding.  If any such obligation is imposed upon the Borrower with respect
to any amount payable by it hereunder or under any of the other Loan Documents,
the Borrower will pay to the Lender such additional amount in U.S. Dollars as
shall be necessary to enable the Lender to receive the same net amount which the
Lender would have received on such due date had no such obligation been imposed
upon the Borrower.  The Borrower will deliver promptly to the Lender
certificates or other valid vouchers or other evidence of payment reasonably
satisfactory to the Lender for all taxes or other charges deducted from or paid
with respect to payments made by the Borrower hereunder or under such other Loan
Document. The Lender may, and the Borrower hereby authorizes the Lender to,
debit the amount of any payment not made by such time to the Borrower's
operating account with the Lender or to the Note Record.

     2.8  LIBOR Indemnity.  If the Borrower for any reason (including, without
          ---------------                                                     
limitation, pursuant to Sections 2.6(b) and 8.2 hereof) makes any payment of
principal with respect to any LIBOR Loan on any day other than the last day of
an Interest Period applicable to such LIBOR Loan, or fails to borrow or continue
or convert to a LIBOR Loan after giving a Notice of Borrowing or Conversion
thereof pursuant to Section 2.3 and in reliance on such notice the Lender has
made such LIBOR Loan (of if such LIBOR Loan has not yet been made, the Lender
has obtained or committed to obtain matched funding for such LIBOR Loan), or
fails to prepay a LIBOR Loan after having given notice thereof as provided in
Section 2.6(a), the Borrower shall pay to the Lender an amount computed pursuant
to the following formula:

                              L = (R - T) x P x D
                                  ---------------
                                       360

          L =  amount payable to the Lender
          R =  interest rate on such LIBOR Loan
          T =  effective interest rate per annum at which any readily marketable
               bond or other obligation of the United States, selected at SSB's
               reasonable discretion, maturing on or near the last day of the
               then applicable Interest Period of such LIBOR Loan and in
               approximately the same amount as such Loan can be purchased by
               SSB on the day of such payment of principal or failure to borrow,
               continue, convert or prepay
          P =  the amount of principal prepaid or the amount of the requested
               Loan or the amount of the prepayment not made
          D =  the number of days remaining in the Interest Period as of the
               date of such payment or failure or the number of days of the
               requested Interest Period

The Borrower shall pay such amount upon presentation by the Lender of a
statement setting forth the amount and the Lender's calculation thereof pursuant
hereto, which statement shall be deemed true and correct absent manifest error.

     2.9   Computation of Interest and Fees.  Interest and all fees payable
           --------------------------------                                
hereunder shall be computed daily on the basis of a year of 360 days and paid
for the actual number of days for which due.  If the due date for any payment of
principal is extended by operation of law, interest shall be payable for such
extended time.  If any payment required by this Agreement becomes due on a day
that is not a Business Day such payment may be made on the next succeeding
Business Day (subject to the definition of the term "Interest Period"), and such
extension shall be included in computing interest in connection with such
payment.

     2.10  Changed Circumstances; Illegality.
           --------------------------------- 

          (a) Notwithstanding any other provision of this Agreement, in the
event that, for reasons beyond the Lender's reasonable control:

          (i)  on any date on which the LIBOR Rate would otherwise be set the
     Lender shall have determined in good faith (which determination shall be
     final and conclusive) that adequate and fair means do not exist for
     ascertaining the LIBOR Rate, or

          (ii  at any time the Lender shall have determined in good faith (which
     determination shall be final and conclusive that:

          (A) the making or continuation of or conversion of any Loan to a LIBOR
     Loan has been made impracticable or unlawful by (1) the occurrence of a
     contingency that materially and adversely affects the interbank LIBOR
     market or (2) compliance by the Lender in good faith with any applicable
     law or governmental regulation, guideline or order or interpretation or
     change thereof by any governmental authority charged with the
     interpretation or administration thereof or with any request or directive
     of any such governmental authority (whether or not having the force of
     law); or

          (B) the LIBOR Rate shall no longer represent the effective cost to the
     Lender for U.S. dollar deposits in the interbank market for deposits in
     which it regularly participates;

then, and in any such event, the Lender shall forthwith so notify the Borrower
thereof.  Until the Lender notifies the Borrower that the circumstances giving
rise to such notice no longer apply, the obligation of the Lender to allow
selection by the Borrower of the Type of Loan affected by the contingencies
described in this Section (herein called "Affected Loans") shall be suspended.
                                          --------------                       
If, at the time the Lender so notifies the Borrower, the Borrower has previously
given the Lender a Notice of Borrowing or Conversion with respect to one or more
Affected Loans but such Loans have not yet gone into effect, such notification
shall be deemed to be a request for Prime Rate Loans.

          (b) In the event of a determination of illegality pursuant to
subsection (a)(ii)(A) above, the Borrower shall, with respect to the outstanding
Affected Loans, prepay the same, together with interest thereon and any amounts
required to be paid pursuant to Section 2.8, on such date as shall be specified
in such notice (which shall not be earlier than the date such notice is given)
and may, subject to the conditions of this Agreement, borrow a Loan of another
Type in accordance with Section 2.1 hereof by giving a Notice of Borrowing or
Conversion pursuant to Section 2.3 hereof.

     2.11  Increased Costs.  In case any change in law, regulation, treaty or
           ---------------                                                   
official directive or the interpretation or application thereof by any court or
by any governmental authority charged with the administration thereof or the
compliance with any guideline or request of any central bank or other
governmental authority (whether or not having the force of law):

          (i)  subjects the Lender for reasons beyond its reasonable control to
     any tax with respect to payments of principal or interest or any other
     amounts payable hereunder by the

                                      -14-

     Borrower or otherwise with respect to the transactions contemplated hereby
     (except for taxes on the overall net income of the Lender imposed by the
     United States of America or any political subdivision thereof), or

          (ii)  for reasons beyond the Lender's reasonable control, imposes,
     modifies or deems applicable any deposit insurance, reserve, special
     deposit or similar requirement against assets held by, or deposits in or
     for the account of, or loans by, the Lender (other than such requirements
     as are already included in the determination of the LIBOR Rate), or

          (iii) for reasons beyond the Lender's reasonable control, imposes upon
     the Lender any other condition with respect to its obligations or
     performance under this Agreement or in respect of any Letter of Credit,

and the result of any of the foregoing is to increase the cost to the Lender,
reduce the income receivable by the Lender or impose any expense upon the Lender
with respect to any Loans or its obligations under this Agreement or in respect
of any Letter of Credit, the Lender shall notify the Borrower thereof.  The
Borrower agrees to pay to the Lender the amount of such increase in cost,
reduction in income or additional expense as and when such cost, reduction or
expense is incurred or determined, upon presentation by the Lender of a
statement in the amount and setting forth in reasonable detail the Lender's
calculation thereof and the assumptions upon which such calculation was based,
which statement shall be deemed true and correct absent manifest error.

     2.12  Capital Requirements.  If after the date hereof the Lender determines
           --------------------                                                 
that, for reasons beyond the Lender's reasonable control, (i) the adoption of or
change in any law, rule, regulation or guideline regarding capital requirements
for banks or bank holding companies, or any change in the interpretation or
application thereof by any governmental authority charged with the
administration thereof, or (ii) compliance by the Lender or its parent bank
holding company with any guideline, request or directive of any such entity
regarding capital adequacy (whether or not having the force of law), has the
effect of reducing the rate of return on the Lender's or such holding company's
capital as a consequence of the Lender's Commitment hereunder or its obligations
in respect of any Letter of Credit to a level below that which the Lender or
such holding company could have achieved but for such adoption, change or
compliance (taking into consideration the Lender's or such holding company's
then existing policies with respect to capital adequacy and assuming the full
utilization of such entity's capital) by any amount deemed by the Lender to be
material, then the Lender shall notify the Borrower thereof.  The Borrower
agrees to pay to the Lender the amount of such reduction of its rate of return
on capital as a consequence of the Lender's Commitment hereunder or its
obligations in respect of any Letter of Credit as and when such reduction is
determined, payable within 90 days after presentation by the Lender of a
statement in the amount and setting forth in reasonable detail the Lender's
calculation thereof and the assumptions upon which such calculation was based
(which statement shall be deemed true and correct absent manifest error) unless
within such 90 day period the Borrower shall have prepaid in full all
Obligations to the Lender, in which event no amount shall be payable to the
Lender under this Section.  In determining such amount, the Lender may use any
reasonable averaging and attribution methods.

     2A.1  Issuance.  Upon the terms and subject to the conditions hereof, SSB,
           --------                                                            
in reliance upon the representations and warranties of the Borrower contained
herein, agrees to issue letters of credit (the "Letters of Credit") for the
                                                -----------------          
account of the Borrower in such form as may be requested from time to time by
the Borrower and agreed to by SSB, provided that the Total Outstandings (after
                                   --------                                   
giving effect to all requested Loans and Letters of Credit) shall not at any
time exceed the

                                      -15-
<PAGE>
 
Maximum Amount, and provided further that no Letter of Credit shall have an
                    ----------------   
expiration date later than the Maturity Date. At least three (3) Business Days
prior to the proposed issuance date of any Letter of Credit, the Borrower shall
deliver to SSB a Letter of Credit Application setting forth the Maximum Drawing
Amount of all Letters of Credit (including the requested Letter of Credit), the
requested language of the requested Letter of Credit and such other information
as SSB shall require. Each request for the issuance of a Letter of Credit
hereunder shall constitute a representation and warranty by the Borrower that
the conditions set forth in Sections 3.1 and 3.2 have been satisfied as of the
date of such request.

     2A.2  Reimbursement Obligation of the Borrower.  In order to induce SSB to
           ----------------------------------------                            
issue, extend and renew each Letter of Credit, the Borrower hereby agrees to
reimburse or pay to SSB with respect to each Letter of Credit issued, extended
or renewed by SSB hereunder as follows:

          (a) on each date that any draft presented under any Letter of Credit
is honored by SSB or SSB otherwise makes payment with respect thereto, (i) the
amount paid by SSB under or with respect to such Letter of Credit, and (ii) the
amount of any taxes, fees, charges or other costs and expenses whatsoever
incurred by SSB in connection with any payment made by SSB under, or with
respect to, such Letter of Credit; and

          (b) upon the Maturity Date or the acceleration of the Reimbursement
Obligations pursuant to Section 8, an amount equal to 100% of the then Maximum
Drawing Amount of all Letters of Credit, which amount shall be held by SSB as
cash collateral for all Reimbursement Obligations.  Amounts so held by SSB by
reason of this or any other provision of this Agreement shall be held in
interest-bearing accounts and shall be applied, together with any interest
accrued thereon, in satisfaction of Reimbursement Obligations or, when and if
such Reimbursement Obligations have been satisfied in full by the Borrower or by
such application by SSB, any excess of such amounts so held shall be refunded by
SSB to the Borrower.

Each such payment shall be made to SSB at SSB's head office in immediately
available funds. Interest on any and all amounts remaining unpaid by the
Borrower under this Section 2A.2 at any time from the date such amounts become
due and payable (whether as stated in this Section 2A.2, by acceleration or
otherwise) until payment in full (whether before or after judgment) shall be
payable to the Lender, on demand at a rate per annum equal to 2% above the
interest rate applicable to Prime Rate Loans at the time in the absence of an
Event of Default, unless such payment is funded by a Loan, in which case such
Loan shall bear interest as provided in Section 2.4 above.

     2A.3  Letter of Credit Payments.  If any draft shall be presented or other
           -------------------------                                           
demand for payment shall be made under any Letter of Credit, SSB shall notify
the Borrower of the date and amount of the draft presented or demand for payment
and of the date and time when it expects to pay such draft or honor such demand
for payment.  The responsibility of SSB to the Borrower shall be only to
determine that the documents (including each draft) delivered under each Letter
of Credit in connection with such presentment shall be in conformity in all
material respects with such Letter of Credit in accordance with the UCP.  All
such unpaid Reimbursement Obligations with respect to Letters of Credit shall be
deemed to be Revolving Credit Loans.

     2A.4  Obligations Absolute.
           -------------------- 

          (a) Subject to the second sentence of Section 2A.3 above:  (i) The
Borrower's Reimbursement Obligations shall be absolute and unconditional under
any and all circumstances and irrespective of the occurrence of any Default or
Event of Default or any condition precedent whatsoever or any set off,
counterclaim or defense to payment which the Borrower may have or have had
against the Lender or any beneficiary of a Letter of Credit; and (ii) the
Borrower further agrees that the Lender shall not be responsible for, and the
Borrower's Reimbursement Obligations

                                      -16-
<PAGE>
 
shall not be affected by, among other things, the validity or genuineness of
documents or of any endorsements thereon, even if such documents should in fact
prove to be in any or all respects invalid, fraudulent or forged, or any dispute
between or among the Borrower, the beneficiary of any Letter of Credit or any
financing institution or other party to which any Letter of Credit may be
transferred or any claims or defenses whatsoever of the Borrower, against the
beneficiary of any Letter of Credit or any such transferee.

          (b) Subject to the second sentence of Section 2A.3 above, the Lender
shall not be liable for any error, omission, interruption or delay in
transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit.  The Borrower agrees that
any action taken or omitted by the Lender under or in connection with each
Letter of Credit and the related drafts and documents, if done in good faith,
shall be binding upon the Borrower and shall not result in any liability on the
part of the Lender to the Borrower.

     2A.5  Reliance by the Lender.  To the extent not inconsistent with Section
           ----------------------                                              
2A.4, the Lender shall be entitled to rely, and shall be fully protected in
relying upon, any Letter of Credit, draft writing, resolution, notice, consent,
certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype
message, statement, order or other document believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons
and upon advice and statements of legal counsel, independent accountants and
other experts selected by the Lender.

covenants, agreements, representations and warranties made herein, in the other
Loan Documents or in any documents or other papers delivered by or on behalf of
the Borrower pursuant hereto shall be deemed to have been relied upon by the
Lender, notwithstanding any investigation heretofore or hereafter made by it,
and shall survive the making by the Lender of the Loans as herein contemplated,
and shall continue in full force and effect so long as any Obligation remains
outstanding and unpaid or the Lender has any obligation to make any Loans

<PAGE>
 
THAN, OR IN ADDITION TO, ACTUAL DAMAGES. THE BORROWER (a) CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF THE LENDER HAS REPRESENTED, EXPRESSLY OR
OTHERWISE, THAT THE LENDER WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO
ENFORCE THE FOREGOING WAIVERS AND (b) ACKNOWLEDGES THAT THE LENDER HAS BEEN
INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS TO WHICH IT IS
A PARTY BECAUSE OF, AMONG OTHER THINGS, THE BORROWER'S WAIVERS AND
CERTIFICATIONS CONTAINED HEREIN.

PLEAD OR CLAIM IN ANY SUCH ACTION THAT SUCH ACTION HAS BEEN BROUGHT IN AN
INCONVENIENT FORUM.

     10.13 Severability. The provisions of this Agreement are severable and if
           ------------                                                      
any one clause or provision hereof shall be held invalid or unenforceable in
whole or in part in any jurisdiction, then such invalidity or unenforceability
shall affect only such clause or provision, or part thereof, in such
jurisdiction, and shall not in any manner affect such clause or provision in any
other jurisdiction, or any other clause or provision of this Agreement in any
jurisdiction.

     10.14 Confidentiality.  The Lender will endeavor in good faith to maintain
           ---------------
the confidentiality of any non-public information relating to the Borrower which
has been identified in writing as confidential on the information itself or
otherwise (the "Confidential Information") and, except as provided below, will

own proprietary information to prevent the unauthorized disclosure of the
Confidential Information to third parties. Confidential Information shall not
include information that either: (a) is in the public domain; or (b) is
disclosed to the Lender by a third party, provided the Lender does not have

Confidential Information by the Lender that is, in the good faith opinion of the
Lender, compelled by laws, regulations, rules, orders or legal process or
proceedings or is disclosed to: (a) any party, including a prospective
participant, who has signed a confidentiality agreement containing terms
substantially similar to those contained herein; (b) legal counsel, examiners;

              ---------------------------------------------------

3.1 (b) - Litigation:
- ---------------------
      The Borrower recently received a letter from an attorney on behalf of the 
holder of a patent on a system for scanning and encoding images from a personal 
indentification card. Although the Borrower believes that its product does not 
infringe such patent, there can be no assurance that such patent holder will not
initiate litigation with respect to this patent or allege additional claims. 
There can be no assurance that the Borrower would prevail in any litigation 
seeking damanges or expenses from the Borrower or to enjoin the Borrower from 
selling its products on the basis of any alleged infringement.

      On September 23, 1996, three minority shareholders of Lau Acquisition 
Corp. ("Lau") filed suit against Lau, the Borrower and others in Superior Court 
in Berkshire County, Massachusetts, alleging that certain defendants breached 
the fiduciary duty owed the plaintiffs as shareholders of Lau. The plaintiffs 
requested, among other things, an injunction to delay the initial public 
offering of the Borrower's common stock in an effort to obtain a direct, rather 
than an indirect, ownership interest in the Borrower. On October 4, 1996, the 
Superior Court denied plaintiffs' request for such relief, although plaintiffs' 
claims for unspecified money damages remain pending.

thereunder which are applicable to contracts with the United States Government 
and generally are incorporated into the terms of Borrower's contracts with 
contractors of the United States Government. We also note that many of the

require the consent of such parties befoe such contracts can be assigned; only 
some of such consents have been requested or obtained as of the date hereof.
