Third Quarter 1995 Compared with Third Quarter 1994
- ---------------------------------------------------

The nature of the Company's business is such that year to year changes in sales
levels are predominantly due to changes in shipping volume or product mix rather
than changing sales prices. Net sales for the third quarter of 1995 were $15.9
million, a 31% increase when compared with $12.1 million for the same period in
1994.

The following chart provides the sales breakdown by product line for the third
quarter:

</TABLE>

Sales in the Electronic Systems segment (net of intercompany eliminations)
increased 29% to $13.3 million from $10.4 million for the same period in 1994.
The sales increase was primarily attributable to higher systems integration
revenue, partially offset by lower component revenue and service revenue. The
increase in systems integration revenue was principally attributable to higher
systems integration revenue from NAI's Systems and Lynwood Divisions. The
decrease in service and component revenue is primarily attributable to the lower
revenue from Codar Technology and the closing of the Military Products Division
which was consolidated into Codar in September 1994.

The 1994 third quarter had approximately $1.7 million of revenue produced at the
Hauppauge facility which was subsequently closed in September 1994 when the
Military Products Division was consolidated into one location at Codar. The
merging of the two businesses has placed significant strain on Codar which has
resulted in delayed shipments, significant cost overruns on long-term contracts,
large losses and significant cash constraints.

Sales in the Telecommunications segment increased 49% to $2.5 million as
compared to $1.7 million for the same period in 1994. The increase in sales was
attributable to higher line treatment revenue which increased 53% due to initial
deliveries of Wilcom's new Enhanced Line Powered Amplifier products. The test
equipment revenue increased as a result of increased orders from the regional
Bell operating companies.

The consolidated gross margin percentage for the third quarter of 1995 was 11.3%
as compared with 22.0% for the same period in 1994. The gross margin percentage
was adversely affected by a $1.4 million charge to operations and an unfavorable
mix of high and low margin product deliveries. The $1.4 million charge to
operations was attributable to cost growth on certain long-term contracts due to
engineering design changes, greater than anticipated


<PAGE>


                                                                          Page 9

labor and material costs and under absorbed overhead expense. Although margins
are expected to improve, low margins are expected to continue at least during
the fourth quarter of 1995 principally at Codar due to a disproportionate level
of low margin revenue as a result of past cost overruns on certain long-term
contracts for which the Company continues to provide products.

Selling expense for the third quarter of 1995 was $1.3 million as compared with
$1.6 million for the same period in 1994. This decrease is attributable to
savings associated with the consolidation of the Military Products Division in
the third quarter of 1994.

General and administrative expenses for the third quarter of 1995 were $1.4
million as compared with $1.2 million for the same period in 1994. This increase
is primarily attributable to higher general and administrative expenses at the
Codar subsidiary as a result of increased management resources, partially offset
by the savings associated with the previously mentioned consolidation in 1994.
The 1994 third quarter was favorably impacted by the reversal of certain
over-accruals.

Company-sponsored research and development expenditures for the third quarter of
1995 were $0.4 million as compared with $0.7 million for the same period in
1994. This decrease is attributable to savings associated with the previously
mentioned consolidation and the change in mix between Company-sponsored research
and development and customer-funded research and development. A key component to
the Electronic Systems segment's strategy is to focus on its systems integration
business. Although systems integration work by its nature will require
significant engineering content, such costs must be classified as contract costs
and charged to cost of sales as opposed to Company-sponsored research and
development (IR&D).

For the third quarter of 1995 the Company had an operating loss of $1.5 million
as compared with a loss of $0.9 million for the same period in 1994. The
operating loss was primarily attributable to the $1.4 million charge previously
noted.

Interest expense, net of interest income, was $0.7 million in the third quarter
of 1995, as compared with $0.4 million in the comparable quarter of 1994. The
second quarter of 1995 also included a $0.3 million charge for debt
restructuring expense related to the April 7, 1995 agreement reached with the
Company's two lending institutions.

The Company was unable to recognize a tax benefit for its loss in the third
quarter of 1995 due to uncertainties as to whether or not a future benefit will
be realized. Any earnings in 1995 will not be taxed at the statutory rate. The
small tax provision is associated with Lynwood Scientific Developments Ltd., the
Company's U.K. subsidiary.

For the third quarter of 1995 the Company had a net loss of $2.3 million as
compared with a net loss of $0.8 million in the third quarter of 1994. Loss per
share was $(0.31) as compared with $(0.12) for the same period in 1994, based on
a weighted average of 7.5 million and 6.8 million shares outstanding,
respectively.

First Nine Months 1995 Compared with First Nine Months 1994
- -----------------------------------------------------------

The nature of the Company's business is such that year to year changes in sales
levels are predominantly due to changes in shipping volume or product mix rather
than changing sales prices. Net sales for the first nine months of 1995 were
$42.7 million, basically unchanged when compared with $42.5 million for the same
period in 1994.

nine months:

</TABLE>

The sales increase was primarily attributable to higher systems integration
revenue, partially offset by lower component and service revenues. The increase
in systems revenue was principally attributable to higher systems integration
revenue from NAI's Systems Division. The decrease in service and component
revenue is primarily attributable to lower revenue from Codar Technology and the
closing of the Military Products Division which was consolidated into Codar in
September 1994.

The Company expects a significant amount of 1995 sales to be directly to the
military or through prime contractors to the military. The Company is not aware
of any programs in which it participates that are specifically targeted for
termination or curtailment. The Company's products are utilized on many
different U.S. Government programs which reduces the adverse impact of
cancelling a single specific program. However, changes in future U.S. defense
spending levels could impact the Company's future sales volume.

Sales in the Telecommunications segment increased 1% to $6.1 million as compared
to $6.0 million for the same period in 1994. The increase in sales was
attributable to higher line treatment revenue due to deliveries of Wilcom's new
Enhanced Line Powered Amplifier products. Test equipment revenue decreased due
to lower orders from the regional Bell operating companies and foreign
telecommunications companies primarily due to their cost cutting measures.

The consolidated gross margin percentage for the first nine months of 1995 was
5.8% as compared with 19.9% for the same period in 1994. The gross margin
percentage was adversely affected by a $6.1 million charge to operations and an
unfavorable mix of high and low margin product deliveries. The $6.1 million
charge to operations was attributable to cost growth on certain long-term
contracts due to engineering design changes, greater than anticipated labor and
material and overhead costs and increased provisions for slow moving, excess and
obsolete inventory. Low margins are expected to continue at least during the
fourth quarter of 1995 principally at Codar due to a disproportionate level of
low margin revenue as a result of past cost overruns on certain long-term
contracts for which the Company continues to provide products.

Selling expense for the first nine months of 1995 was $3.8 million as compared
with $6.0 million for the same period in 1994. This decrease is attributable to
savings associated with the consolidation of the military products division in
the third quarter of 1994.

General and administrative expenses for the first nine months of 1995 were $4.2
million as compared with $4.3 million for the same period in 1994. This decrease
is primarily attributable to savings associated with the previously mentioned
consolidation in 1994, partially offset by higher general and administrative
expenses at the Codar subsidiary as a result of increased management resources.

Company-sponsored research and development expenditures for the first nine
months of 1995 were $1.5 million as compared with $2.7 million for the same
period in 1994. This decrease is attributable to savings associated with the
previously mentioned consolidation and the change in mix between Company-
sponsored research and development and customer-funded research and development.
A key component to the Electronic Systems segment's strategy is to focus on its
systems integration business. Although systems integration work by its nature
will require significant engineering content, such costs must be classified as
contract costs and charged to cost of sales as opposed to Company-sponsored
research and development (IR&D).

For the first nine months of 1995 the Company had an operating loss of $7.3
million as compared with a loss of $12.1 million for the same period in 1994.
The operating loss in 1995 was primarily due to the $6.1 million charge
previously noted and lower sales volume. The 1994 operating loss included a $7.3
million restructuring expense.

Interest expense, net of interest income, was $1.7 million in the first nine
months of 1995, as compared to $1.0 million for the same period in 1994. The
first nine months of 1995 also included a $0.6 million charge for debt
restructuring expense related to the April 7, 1995 agreement reached with the
Company's two lending institutions.

The effective income tax expense rate is below the combined statutory federal
and state rates for the first nine months of 1995. The Company was unable to
recognize a tax benefit for its loss in the first nine months of 1995 due to
uncertainties as to whether or not a future benefit will be realized. Any
earnings in 1995 will not be taxed at the statutory rate.

For the first nine months of 1995 the Company had a net loss of $9.2 million as
compared with a net loss of $8.5 million in the first nine months of 1994. Loss
per share was $(1.25) as compared with $(1.26) for the same period in 1994,
based on a weighted average of 7.4 million and 6.8 million shares outstanding,
respectively. The 1994 loss per share includes a pre-tax restructuring charge of
$7.3 million.

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

Although the Company reported a net loss of $9.2 million in the first nine
months of 1995, it still generated a positive cash flow of $0.8 million from
operations due to the receipt in January of a Federal tax refund of $4.0 million
attributable to the 1994 tax loss carryback. Company operations have
historically provided a positive cash flow. However, the Company is currently
experiencing financial difficulties due to lower shipping volumes and cost
overruns on certain long-term contracts.

Although the third quarter revenue level was up approximately 13% over the
second quarter revenue level, the lower than normal gross margins resulted in
continuing losses and the Company must continue to increase its shipment rate to
improve its operating margin. However, its ability to do so is constrained by a
shortage of working capital.

The restructuring actions taken in 1994 have significantly reduced the expense

                                                                         Page 12

structure of the Company. However, it is not certain that the Company will be
able to achieve the revenue level necessary to return to profitability. The
Company is taking action to minimize its cash outlays by deferring or
eliminating discretionary expenses and capital asset purchases. The Company must
increase its shipment rate to an acceptable level within the near future, or
obtain additional financing, in order to meet its cash flow requirements during
1995.

On April 7, 1995 the Company entered into an amended and restated credit
agreement with its two primary lending institutions. Under the terms of the new
agreement, the existing term debt and lines of credit were converted into a
revolving credit line in exchange for a cash payment of $100,000 and the
issuance of 250,000 shares of the Company's Common Stock. The new agreement
required quarterly principal payments, commencing in September 1995, of $875,000
with a balloon payment of $13,425,000 due on January 15, 1996. At July 1, 1995
the Company was in violation of certain debt covenants of this new agreement.
The defaults have been waived and the agreement has been amended to establish
new covenants. In addition, payment of a fee of $50,000 and the quarterly
principal payments which were scheduled to begin in September 1995 were deferred
and added to the balloon payment due on January 15, 1996. On October 13, 1995,
the Company received a limited waiver for certain financial covenant defaults.

The payment of the $15,175,000 principal obligation in January 1996 will be
dependent upon the Company's ability either to obtain alternate financing or to
restructure the remaining balance due. The Company is considering several
alternatives to achieve this, including the sale of common or preferred stock,
the issuance of convertible debt, a business combination, the sale of all or a
portion of the Company and the establishment of a borrowing relationship with
new lending institutions.

On October 16, 1995 the Company announced that a private investor had made a
subordinated loan to the Company of $1,000,000 due January 15, 1996. The loan is
exchangeable for the Company's 12% Convertible Subordinated Promissory Notes due
in 2000, convertible into 500,000 shares of Common Stock at a conversion rate of
$2.00 per share, and warrants representing the right to acquire 850,000 shares
of Common Stock at an exercise price of $2.50, subject to adjustment. Charles S.
Holmes, a representative of the Long Island based investor, became a director of
NAI. The Company is also discussing with other private investors the investment
of up to an additional $7 million in the 12% Convertible Subordinated Notes and
Warrants to purchase shares of Common Stock at $2.50 per share. Such discussions
are preliminary. If all transactions are consummated, following the exercise of
the warrants and the conversion of the notes, an aggregate of 8,000,000 shares
of Common Stock, or approximately 49.6% of the then outstanding fully diluted
Common Stock of the Company, will have been issued for an aggregate
consideration of $18,000,000. Approval of the Company's shareholders will be
required for the consummation of the transaction.

The restructuring of the timing of repayment of the outstanding principal under
the Company's bank credit facilities is a condition to the consummation of the
proposed new investment. The Company anticipates that, if it is successful in
raising the additional funds, it will be able to restructure its credit
facilities to permit repayment over a longer period.

At September 30, 1995 the Company's long-term secured debt totaled $15.7 million
of which current installments were $15.4 million. This compares to $16.2 million
at December 31, 1994 of which current installments were $2.2 million. The
Company's long-term borrowings, secured by plant and equipment, bear interest at
rates ranging from 70% of prime (8.75% at September 30, 1995) to 12.43%.

Cash and cash equivalents totaled $1.4 million at September 30, 1995 as compared
to $1.7 million at December 31, 1994. Cash provided by operating activities
amounted to $0.8 million in the first nine months of 1995 as

compared to cash used in operating activities of $0.6 million in the first nine
months of 1994. In January 1995, the Company received a Federal tax refund of
$4.0 million.

For the first nine months of 1995 the Company used cash of $0.4 million for the
purchase of property, plant and equipment. In May 1995, the Company sold its
vacated manufacturing facility located in Hauppauge, NY, and received cash of
$0.4 million with a note for the balance payable in two years in the amount of
$1.2 million.

For the first nine months of 1995, the Company made debt principal payments of
$0.5 million and payments against notes payable of $0.1 million.


Inflation
- ---------

The Company's financial statements are prepared in accordance with historical
accounting systems, and therefore do not reflect the effect of inflation. The
impact of changing prices on the financial statements is not considered to be
significant.


Backlog
- -------

The backlog of unfilled orders at September 30, 1995 stood at $49.2 million
compared to $39.3 million at October 1, 1994. Approximately 80% of the backlog
is scheduled for delivery over the next twelve months.

                  On October 16, 1995 the Company announced that a private
                  investor had made a subordinated loan to the Company of
                  $1,000,000 due January 15, 1996. The loan is exchangeable for

                  Company, will have been issued for an aggregate consideration
                  of approximately $18,000,000. Approval of the Company's
                  shareholders and consent from the Company's banks will be
                  required for the consummation of the transaction.

                  The Company also announced the relocation of the executive and
                  administrative offices of the Company from Woodbury, New York
                  to Longmont, Colorado in December 1995.

                  The Company stated that the new loan will provide needed
                  working capital. The Company is currently required to repay
                  the outstanding principal amount of $15,225,000 under its bank
                  credit facilities on January 15, 1996. The restructuring of
                  the timing of repayment is a condition to the consummation of

authorized the execution and delivery of this Agreement and the Exhibits to
which it is or is to be a party, the issuance of the Note and the Exchange

the purchase or acquisition from the Company of any shares of its capital stock.
There are no existing voting trusts, voting agreements or similar agreements
between the Company and any of its stockholders, nor, to the best knowledge of
the Company (after reasonable inquiry), are there any such agreements among any

subject to any preemptive or other preferential rights under the Restated
Certificate of Incorporation of the Company or under any agreement to which the

partnership or other entity duly organized, validly existing and in good
standing under the laws of its jurisdiction of organization, has all requisite

Subsidiary.

         3.4 Qualification. Each of the Company and each Subsidiary is duly
qualified or licensed and in good standing and is duly authorized to do business
in each jurisdiction (other than, in the case of a corporation, the jurisdiction
of incorporation) in which the nature of the activities or the character of the
properties owned or leased makes such qualification or licensing necessary
except for jurisdictions in which the failure to be so qualified would not have
a Material Adverse Effect.

         3.5 Compliance with Laws, Other Instruments; No Conflicts, etc. Neither
the Company nor any Subsidiary is (a) in violation of any term or provision of
its corporate charter or by-laws or other organizational documents, or, to the
Company's knowledge, (b) in violation of or in default under any term or
provision of any agreement, indenture, mortgage, instrument, permit or license
to which it is a party or by which it or any of its properties may be bound or
affected, or any existing statute, law, governmental rule, regulation or
ordinance, or any order of any court, arbitrator or Governmental Body applicable
to it or its properties, the consequences of which violation or default, either
in any one case or taken together with all other such violations or defaults,
(x) could have a Material Adverse Effect or (y) could materially and adversely
affect the ability of the Company to perform its obligations under this
Agreement, the Note or any other Exhibit to which the Company is or is to be a
party.

         3.6 Consents and Approvals. Except for the Required Consents set forth
in Schedule 3.6, no approval by, from or with, and no other action in respect
of, any Governmental Body or any other Person (including any trustee or holder

delivery by the Company of, or the performance by the Company of any obligation
under, this Agreement, the Note or any other Exhibit to which it is or is to be
a party or the consummation by the Company of the transactions contemplated
hereby and thereby or (b) as a condition to the legality, validity or
enforceability as against the Company of this Agreement, the Note or any other
Exhibit to which it is or is to be a party.

         3.7 Litigation. Except as set forth on Schedule 3.7, there are no
actions, suits or proceedings pending or, to the knowledge of the Company,
threatened against the Company or any Subsidiary, or affecting any of their
respective properties in any court or before any arbitrator of any kind or
before or by any Governmental Body, which (i) question the validity or legality
of this Agreement, the Note or any other Exhibit to which it is or is to be a
party or any action taken or to be taken pursuant hereto or thereto or (ii)
might result, either in any one case or in the aggregate, in (A) a material
impairment of the ability of the Company to perform its obligations under this
Agreement, the Note or any other Exhibit to which it is or is to be a party, or
(B) a Material Adverse Effect.

         3.8 Private Offering. Neither the Company not any Person acting on
behalf of the Company has taken, or will take, any action which would subject
the issuance or sale of the Note to Section 5 of the Securities Act or to the
registration or qualification requirements of any securities or Blue Sky law of
any applicable jurisdiction.

         3.9 No Defaults; Debt, etc; Authorization. (a) Upon receipt of any
Required Consent, no default or event of default, after giving effect to the
issuance and sale of the Note and the consummation of the transactions
contemplated by this Agreement and the Exhibits, will exist (or, but for the
waiver thereof, would exist), to the Company's knowledge, under any instrument
or agreement evidencing, providing for the issuance or securing of, or otherwise
relating to, any secured or unsecured funded indebtedness of the Company.

                  (b) Upon issuance thereof by the Company and payment therefor
in accordance with the terms of this Agreement, the Note will be duly
authorized, validly issued, fully-paid and nonassessable and will constitute a
legal, valid and binding obligation of the Company enforceable in accordance
with its terms subject to applicable bankruptcy, insolvency, moratorium or
similar laws relating to or affecting creditors' rights generally and the
general principles of equity (regardless of whether enforcement is sought in a
proceeding at law or in equity). The Company further covenants that (i) upon
issuance thereof by the Company in accordance with the terms of this Agreement,
the Exchange Securities will be duly authorized, validly issued,



                                      -5-
<PAGE>


fully-paid and nonassessable and will constitute legal, valid and binding
obligations of the Company enforceable in accordance with their respective terms
subject, in the case of the Exchange Note, to applicable bankruptcy, insolvency,
moratorium or similar laws relating to or affecting creditors' rights generally
and the general principles of equity (regardless of whether enforcement is
sought in a proceeding at law or in equity); and (ii) upon issuance and delivery
of the Underlying Shares and payment of the exercise price or the conversion
price therefor, the Underlying Shares will be duly authorized, validly issued,
fully paid and nonassessable outstanding shares of Common Stock of the Company.

         3.10 SEC Documents. The Company has furnished Purchaser with true and
complete copies of all documents that the Company has filed with the Commission
since January 1, 1995 (the 'SEC Documents'). As of their respective filing
dates, except as amended by filings with the Commission, the SEC Documents
complied in all material respects with the requirements of the Securities
Exchange Act of 1934, as amended (the 'Exchange Act'), as applicable, were
complete and correct in all material respects as of the dates at which the
information was furnished, and contained (as of such dates) no untrue statement
of a material fact nor omitted to state a material fact necessary in order to
make the statements made therein, in light of the circumstances under which they
were made, not misleading. The financial statements of the Company included in
the SEC Documents (the 'Financial Statements') comply as to form in all material
respects with applicable accounting requirements and with the published rules
and regulations of the Commission with respect thereto, have been prepared in
accordance with generally accepted accounting principles applied on a consistent
basis during the periods involved (except as may be indicated in the notes
thereto or, in the case of unaudited statements, as permitted by the rules and
regulations of the Commission) and fairly present the consolidated financial
position of the Company as of the dates thereof and the consolidated results of
its operations and changes in its financial position for the periods then ended
(subject, in the case of unaudited statements, to normal recurring audit
adjustments, provided that the notes and accounts receivable are collectible in
the amounts shown less any reserve shown thereon and inventories are not subject
to write-down, except in either case in an amount not material). The information
contained in this Agreement and the SEC Documents is true, complete and correct
in all material respects and does not contain any untrue statement of a material
fact or omit to state any material fact required to be stated herein or therein
or necessary to make the statements herein or therein not misleading.

         3.11 Changes, etc. Except as set forth in the SEC Documents or as
previously disclosed to Purchaser, there has been no occurrence or development,
whether or not insured against, which has had or could reasonably be expected to
have a Material Adverse Effect since January 1, 1995.

         3.12 Solvency; Regulation G. (a) The Company's assets currently exceed
its liabilities.



                                      -6-
<PAGE>


                  (b) The Company does not own any 'margin stock' as such term
is defined in Regulation G, as amended (12 C.F. R. Part 207), of the Board of
Governors of the Federal Reserve System. The purchase price of the Note will be
used by the Company only for the purposes contemplated hereunder and under the
Note. None of the purchase price will be used, directly or indirectly, for the
purpose of purchasing or carrying any margin stock or for the purpose of
reducing or retiring any indebtedness which was originally incurred to purchase
or carry any margin stock or for any other purpose which might cause any portion
of the purchase price to be considered a 'purpose credit' within the meaning of
Regulation G, as amended, of the Board of Governors of the Federal Reserve
System.

4        REPRESENTATIONS  AND WARRANTIES OF THE PURCHASER. Purchaser represents
and warrants as follows:

         4.1 Investment Representations. (a) Purchaser hereby acknowledges that
the Note is not being registered (i) under the Securities Act or (ii) under any
applicable state securities law; and that the Company's reliance on the
exemption provided by Section 4(2) of the Securities Act and under applicable
state securities laws is predicated in part on the representations hereby made
to the Company in this Agreement.

         (b) Purchaser will not sell or transfer all or any part of the Note
unless and until it shall first have given notice to the Company describing such
sale or transfer and furnished to the Company either (a) an opinion, reasonably
satisfactory to counsel for the Company, of counsel (skilled in securities
matters, selected by the Purchaser and reasonably satisfactory to the Company)
to the effect that the proposed sale or transfer may be made without
registration under the Securities Act and without registration or qualification
under any state law, or (b) an interpretive letter from the Commission to the
effect that no enforcement action will be recommended if the proposed sale or
transfer is made without registration under the Securities Act; provided that,
on or before October 31, 1995, Purchaser may transfer all or any part of the
Note to a general partnership the partners of which include Purchaser, a trust
for the benefit of members of the family of Purchaser and not more than three
employees of the Purchaser or any Subsidiary thereof without complying with the
foregoing provisions of this Section 4.1(b).

         The Purchaser further understands that the Note, unless otherwise
agreed by the Company, bear a legend substantially to the following effect:

         THIS NOTE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
         AMENDED, AND MAY NOT BE SOLD, PLEDGED, HYPOTHECATED, DONATED OR
         OTHERWISE TRANSFERRED WITHOUT COMPLIANCE WITH THE REGISTRATION OR
         QUALIFICATION PROVISIONS OF APPLICABLE FEDERAL SECURITIES LAWS OR
         APPLICABLE EXEMPTIONS THEREFROM.



                                      -7-
<PAGE>


         The Company may refuse to recognize a transfer of the Note on its books
should a holder attempt to transfer such Note otherwise than in compliance with
this Section 4.1.

         (c) Purchaser has adequate means of providing for Purchaser's current
needs and possible contingencies, Purchaser anticipates no need now or in the
foreseeable future to sell the Note which Purchaser is purchasing and Purchaser
can afford the loss of Purchaser's entire investment in the Company.

         (d)  Purchaser is an 'accredited investor' as defined in Regulation D
under the Securities Act.

         (e) Purchaser has such knowledge and experience in financial and
business matters that Purchaser is capable of evaluating the merits and risks of
investment in the Company and of making an informed investment decision.

         (f) Purchaser will be the only owner, beneficial or otherwise, of the
Note being purchased by the Purchaser hereunder.

         (g) The Purchaser is aware that no federal or state agency has passed
upon the Note or made any finding or determination concerning the fairness of
the investment represented thereby.

         (h) Purchaser had an opportunity to ask questions of and receive
answers from representatives of the Company concerning the terms and conditions
of this investment, and all such questions have been answered to the full
satisfaction of the Purchaser. The Company has not rendered any investment or
tax advice to the Purchaser with respect to the suitability of an investment in
the Note or the tax consequences thereof. The Company has urged Purchaser to
consult its own tax adviser concerning any tax matters relating to this
investment.

         (i) The Note which Purchaser is acquiring will be acquired for
Purchaser's own account for investment (subject to the proviso in Section 4.1(b)
hereof). The Purchaser intends to hold the Note indefinitely (subject to the
proviso in Section 4.1(b) hereof) and Purchaser is not purchasing such
securities with a view toward distribution in a manner which would require
registration under the Securities Act, and Purchaser does not presently have any
reasons to anticipate any change in Purchaser's circumstances or other
particular occasion or event which would cause Purchaser to sell the Note which
Purchaser is purchasing hereunder, provided, nevertheless, that the disposition
of Purchaser's property shall at all times be within Purchaser's control.

         (j) Purchaser acknowledges that it has been called to Purchaser's
attention by those individuals with whom Purchaser has dealt in connection with
Purchaser's 



                                      -8-
<PAGE>


investment in the Company that Purchaser's investment in the Company involves
a high degree of risk.


         (k) Purchaser has received no representations or warranties from the
Company other than those set forth herein.

         4.2 Organization and Authority; Default; Etc. Purchaser is authorized
and otherwise duly qualified to purchase and hold the Note and to enter into
this Agreement and the Exhibits hereto to which it is a signatory; represents
that the purchase of the Note will not result in a breach of or violation of the
terms or provisions of, or constitute a default under, any indenture or other
agreement or instrument by which it or its property is bound, or violate any
applicable law, administrative regulation, or court decree; and represents that
it has its principal place of business as set forth in Section 7.6. Purchaser
shall supply any additional written information that may be required by the
Company.

5        AGREEMENTS OF THE COMPANY.  The Company agrees with the
Purchaser as follows:

         5.1 Business Plan Targets. Schedule 5.1 sets forth certain business
plan targets established for the Company by the Purchaser. The Company
acknowledges that such targets are goals for the Company and its operations and
shall, subject to the determination of its Board of Directors, use it best
efforts to achieve such targets as promptly as practicable.

         5.2      Board Representation.  The Company shall use its best efforts
to cause Mr. Charles S. Holmes or another individual designated by Purchaser

sale of the Company's 12% Convertible Subordinated Promissory Notes due 2000, in

                   (i) the Company shall upon, the written request of the
         Purchaser, (A) exchange the Note, in its entirety, for an identical
         principal amount of a note in substantially the form attached as
         Exhibit D (the 'Exchange Note') and, in connection with such exchange,
         (B) issue to the Purchaser a detachable warrant, in substantially the
         form of the warrant attached as Exhibit E, exercisable at $2.50 per
         share for six years and representing the right to acquire 850,000
         shares of Common Stock, subject to adjustment (the 'Exchange Warrant'),
         and (C) enter into a Registration Rights Agreement with the Purchaser
         in substantially the form attached hereto as Exhibit F; and

                  (ii) the Purchaser or its designee shall be entitled, on or
         before January 12, 1996, to purchase, upon written notice to the
         Company, (i) an additional note, in the principal amount of $2,000,000
         (the 'Additional Note') and (ii) warrants representing the right to
         purchase an additional 2,150,000 shares of Common Stock (the
         'Additional Warrant' and, together with the Additional Note, the
         'Additional Securities'), in each case, upon substantially the same
         terms and conditions as the respective securities attached hereto as
         Exhibit D and Exhibit E;

provided, however, if at the time that Purchaser requests that the Company
exchange the Note for the Exchange Note and the Exchange Warrant or issue the
Additional Securities, the Company is not permitted to do so pursuant to
provisions of the Bank Credit Agreement (as such term is defined in the Note),
then any time period otherwise applicable pursuant to the provisions of this
Section 5.3(b) to the exercise of rights by the Purchaser or its designee shall
be tolled and the Company shall take no action that would frustrate the 
Purchaser's exchange or purchase rights under this Section 5.3(b), including
retirement of the Note, until the Company is permitted to do so under the 
Bank Credit Agreement or pursuant to a waiver of the provisions thereof; and
provided further, however, that if at the time that Purchaser exercises his
right that the Company issue the Additional Notes and Additional Warrants the
Common Stock is not authorized to accommodate such issuance, in such instance
the Additional Note and Additional Warrants will not be issued, then any time
period otherwise applicable pursuant to the provisions of this Section 5.3(b) to
the exercise of rights by the Purchaser or its designee shall be tolled and the
Company shall take no action that would frustrate the Purchaser's exchange or 
purchase rights under this Section 5.3(b), including retirement of the Note, 
until such time as sufficient shares are available for reservation for issuance.


In the event that the Purchaser, or a designee of Purchaser, purchases all of
the Additional Securities, the Company shall, upon written notice from the
Purchaser, (i) promptly retain the services of an investment bank, mutually
selected by the Company and the Purchaser, to advise the Company on the sale of
Lynwood and offer Lynwood for sale through such investment bank and (ii) use its
best efforts to promptly cause the resignation of two then-current members of
the Board of Directors of the Company and to cause the vacancies resulting
thereby to be filled by individuals designated by the Purchaser.

                               REQUIRED CONSENTS

                                   LITIGATION

TDA Trading Corp. v. Carlson, et. al.

                   On or about June 28, 1994, TDA Trading Corp. ('TDA'),
individually and on behalf of a class of persons similarly situated, commenced a
securities fraud class action in the United States District Court for the
Eastern District of New York (the 'Court') against Robert A. Carlson, Richard A.
Schneider and NAI Technologies, Inc. ('NAI'). TDA commenced its action, entitled
TDA Trading Corp. v. Carlson, et. al., by filing a complaint (the 'Complaint')
with the Court.

                   TDA's Complaint principally alleges that the defendants
knowingly and/or recklessly misrepresented to the public that they expected
NAI's 1993 fourth quarter and fiscal year sales and earnings results to continue
to increase at levels substantially above those of prior years at a time when
they supposedly knew but failed to disclose that NAI's fourth quarter 1993 sales
of its Navy Standard Teleprinter ('NST') and other products would decrease
precipitously. The Complaint further alleges that, as a result of defendants'
alleged failure to disclose these developments, TDA and other purchasers of NAI
common stock were damaged because, it is alleged, at the time of purchase the
price of NAI common stock had been artificially inflated. Additionally, the
Complaint asserts that at the time that these adverse business developments
allegedly became known to defendants and prior to their dissemination to the
public, defendants Carlson, Schneider and other directors of NAI allegedly sold
shares of NAI stock owned by them personally at price levels described above
which TDA claims were higher than the true value of these shares.

                  As relief, TDA essentially seeks damages in an amount to be
proven at trial, together with costs and expenses, including reasonable
attorneys', accountants' and experts' fees. TDA's Complaint also requests that
the Court declare its action against NAI and the individual defendants to be a
proper class action and certify it as class representative and plaintiff's
counsel as counsel for the class. On March 24, 1995, the Court granted TDA's
motion for class certification. Discovery has commenced and depositions of NAI
officers and directors have been taken.

Evans Arbitration

                  On or about August 14, 1995, Michael W. Evans ('Evans'), a
former employee of CODAR Technologies, Inc. ('CODAR'), a wholly owned subsidiary
of NAI, instituted a breach of contract and breach of employment proceeding
against NAI. Evans commenced this action by filing a Demand for Arbitration
('Claim') with the American Arbitration Association office in Denver, Colorado
('AAA'), the


<PAGE>



remedy provided in the Employment Agreement between Evans and CODAR dated
October 14, 1993 ('Agreement').

                  Evan's Claim principally alleges that NAI violated the
Agreement by failing to compensate Evans, upon his involuntary termination,
vacation pay which he allegedly accrued during his employment pursuant to the
Agreement. Evans further alleges that, at the time of his involuntary
termination, he was denied the severance pay specified by CODAR's employee
policies. Additionally, Evans asserts a failure by NAI to compensate Evans under
a short term incentive provision and to pay bonus, all as allegedly required by
the Agreement.

                  As relief, Evans seeks damages in the amount of $248,000, and
reserves the right to seek additional damages.

Discrimination Complaint

         In June of 1993, an ex-employee of the Company's Wilcom Division in New
Hampshire filed a discrimination complaint with the New Hampshire Commission for
Human Rights and the Equal Employment Opportunity Commission (EEOC). The Company
submitted a written response denying that it engaged in any unlawful
discrimination. The Company is vigorously contesting the complaint. The matter
is now pending before the Boston office of the EEOC. If the claimant prevails,
she would be entitled to reinstatement and backpay from the date of her
employment ended (August 24, 1992) to the date of reinstatement, plus
compensatory damages. Under Title VII of the Civil Rights Act, amended, punitive
damages are also a possibility. The Company believes that it has a strong
defense to the complaint.

Post Award Audit

         The Company is currently involved in discussions with the Defense
Contract Audit Agency in connection with Contract No. DAAH01-91-C-0162,
modifications P00013 and PZ0005, Audit Report Nos. 3121-94G42040017 and
3121-95G42030002.

                   5. Subordination. (a) The Company for itself, its successors
and assigns, covenants and agrees, and each Holder of this Note by its
acceptance of this Note likewise covenants and agrees, that to the extent
provided below the payment of the principal of and interest on this Note is
hereby expressly subordinated and junior in right of payment, to the extent and
in the manner hereinafter set forth, to all Senior Indebtedness. For purposes
hereof, Senior Indebtedness is defined as:

                  (i) the principal of, premium, if any, any interest (including
         without limitation any interest on interest and post-petition interest)
         on, and all obligations of the Company for any costs and expenses with
         respect to, all liabilities of the Company, direct or contingent,
         joint, several or independent, now or hereafter existing, due or to
         become due, whether created directly or acquired by assignment or
         otherwise, under or in respect of that certain Amended and Restated
         Credit Agreement, dated as of April 12, 1995, among, the Company, The
         Bank of New York, Chemical Bank and the other parties referred to
         therein (as heretofore and as hereafter amended, modified and
         supplemented from time to time, the 'Bank Credit Agreement') and any of
         the other Loan Documents (as defined in the Bank Credit Agreement); and

                  (ii)     all extensions, renewals and refundings of any of
         the foregoing.

                  (b) Upon the acceleration of any Senior Indebtedness or upon
the maturity of the entire principal amount of any Senior Indebtedness by lapse
of time, acceleration or otherwise, all such Senior Indebtedness which has been
so accelerated or matured shall first indefeasibly be paid in full in cash
before any payment is made by the Company or any Person acting on behalf of the
Company on account of any obligations evidenced by this Note.

                  (c) The Company shall not pay any obligations evidenced by
this Note if there exists a Default or Event of Default (as such terms are
defined in the instruments evidencing Senior Indebtedness including, without
limitation, the Bank Credit Agreement) with respect to any Senior Indebtedness
(hereinafter referred to as a 'Blockage Event').

                  The Company shall resume payment of this Note and a Blockage
Event shall be deemed to have terminated:

                  (i) when such Default or Event of Default on Senior
         Indebtedness, as applicable, is cured or waived; or

                  (ii) when the Holder hereof shall have cured any such Default
         or Event of Default on Senior Indebtedness to the extent such Default
         or Event of Default can be cured by payment of money, which amount
         shall be added to the principal amount owing to the Holder pursuant to
         this Note; or




                                      -3-
<PAGE>


                  (iii) 180 days after the occurrence of such Default or Event
         of Default, provided, that at the end of such 180 days, if any of the
         following events occurs, the Blockage Event shall continue: (A) a
         Default in payment of any amount with respect to the Senior
         Indebtedness; (B) an acceleration of the Senior Indebtedness; or (C)
         the occurrence of an event of the type described in Section 6 hereof,
         provided further, that a Blockage Event may be deemed to occur, with
         respect to any single specified Default or Event of Default, only once
         for each 360 day period.

                  (d) At any time there exists a Blockage Event, (i) the Company
shall not, directly or indirectly, make any payment of any part of this Note,
(ii) the Holder hereof shall not demand or accept from the Company or any other
Person any such payment or cancel, set off or otherwise discharge any part of
the indebtedness represented by this Note, and (iii) neither the Company nor the
Holder hereof shall otherwise take or permit any action prejudicial to or
inconsistent with the priority position of any holder of Senior Indebtedness
over the Holder of this Note.

                  (e) Any holder of Senior Indebtedness is hereby authorized to
demand specific performance of this Note, whether or not the Company shall have
complied with the provisions hereof applicable to it, at any time when the
Holder hereof shall have failed to comply with any provision hereof applicable
to him. The Holder hereby irrevocably waives any defense based on the adequacy
of a remedy at law which might be asserted as a bar to the remedy of specific
performance hereof in any action brought therefor by any holder of Senior
Indebtedness. The Holder further (i) waives presentment, demand, notice and
protest in connection with all negotiable instruments evidencing Senior
Indebtedness, notice of any loan made, extension granted or other action taken
in reliance hereon and all demands and notices of every kind in connection with
this Note or Senior Indebtedness; and (ii) assents to any renewal, extension or
postponement of the time of payment of Senior Indebtedness or any other
indulgence with respect thereto, to any substitution, exchange or release of
collateral therefor and to the addition or release of any Person primarily or
secondarily liable thereon.

                  (f) The Company and the Holder shall execute and deliver to
any holder of Senior Indebtedness such further instruments and shall take such
further action as such holder of Senior Indebtedness may at any time or times
reasonably request in order to evidence the subordination of the obligations
hereunder and to otherwise carry out the provisions and intent of this Note.

                  (g) No right of any holder of Senior Indebtedness to enforce
the subordination of the obligations shall be impaired by any act or failure to
act by the Company or the Holder or by their failure to comply with this Note or
any other agreement or document evidencing, related to or securing the
obligations hereunder. Without in any way limiting the generality of the
preceding sentence, the holders of Senior Indebtedness may, at any time and from
time to time, without the consent of or notice to the Holder, without incurring
responsibility to the Holder and without impairing or releasing the
subordination provided in this Note or the obligations of the holder hereof to
the holders of



                                      -4-
<PAGE>


Senior Indebtedness, do any one or more of the following: (i) change the
manner, place or terms of payment of, or renew or alter, any Senior 
Indebtedness, or otherwise amend or supplement in any manner, any Senior
Indebtedness or any instrument evidencing the same or any agreement under which
Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise
deal with any property pledged, mortgaged or otherwise securing any Senior
Indebtedness; (iii) release any Person or entity liable in any manner for the
collection of any Senior Indebtedness; and (iv) exercise or refrain from
exercising any rights against the Company or any other Person or entity.

                  (h) In the event that the Company shall make any payment or
prepayment to the Holder on account of the obligations under this Note which is
prohibited by this Section 5, such payment shall be held by the Holder, in trust
for the benefit of, and shall be paid forthwith over and delivered to, the
holders of Senior Indebtedness (pro rata as to each of such holders on the basis
of the respective amounts and priorities of Senior Indebtedness held by them) to
the extent necessary to pay all Senior Indebtedness due to such holders in full
in accordance with its terms (whether or not such Senior Indebtedness is due and
owing), after giving effect to any concurrent payment or distribution to or for
the holders of such Senior Indebtedness.

                  (i) After all Senior Indebtedness indefeasibly is paid in full
and until the obligations under this Note are paid in full, the Holder shall be
subrogated to the rights of holders of Senior Indebtedness to the extent that
distributions otherwise payable to the Holder have been applied to the payment
of Senior Indebtedness. For purposes of such subrogation, no payments or
distributions to holders of such Senior Indebtedness of any cash, property or
securities to which the Holder would be entitled except for the provisions of
this Section 5 and no payment over pursuant to the provisions of this Section 5
to holders of such Senior Indebtedness by the Holder, shall, as between the
Company, its creditors, other than holders of such Senior Indebtedness, and the
Holder, be deemed to be a payment by the Company to or on account of such Senior
Indebtedness, it being understood that the provisions of this Section 5 are
solely for the purpose of defining the relative rights of the holders of such
Senior Indebtedness, on the one hand, and the Holder hereof, on the other hand.

                  6. Primacy of Senior Indebtedness Claims as Against the
Holder. In any insolvency, receivership, bankruptcy, dissolution, liquidation or
reorganization proceeding, or in any other proceeding, whether voluntary or
involuntary, by or against the Company under any bankruptcy or insolvency law or
laws relating to relief of debtors, to compositions, extensions, or
readjustments of indebtedness:

                  (a) the claims of any holders of Senior Indebtedness against
         the Company shall be paid indefeasibly in full in cash before any
         payment is made to the Holder of this Note;

                  (b) until all Senior Indebtedness is indefeasibly paid in full
         any distribution to which the Holder would be entitled but for this
         Section 6 shall be made to holders of Senior Indebtedness; and



                                      -5-
<PAGE>


                   (c) the holders of Senior Indebtedness shall have the right
to enforce, collect and receive every such payment or distribution and give
acquittance therefor. In furtherance of the foregoing, in the event that the
Company shall file or have filed against it a petition under any chapter of
Title 11 of the United States Code or any comparable statute, with the result
that the Company is excused from the obligation to pay all or any part of the
amount otherwise payable in respect of the Senior Indebtedness during the period
subsequent to the commencement of such proceedings, the Holder agrees that all
or such part of such amount shall be payable out of, and to that extent diminish
and be at the expense of, the Holder's reorganization dividends or other
distributions in respect of any claim filed by it as a creditor or interest
holder. In the event the holders of Senior Indebtedness receive amounts in
excess of payment in full (in cash) of amounts outstanding in respect of Senior
Indebtedness (without giving effect to whether claims in respect of the Senior
Indebtedness are allowed in any insolvency proceeding), the holders of the
Senior Indebtedness shall pay such excess amounts to the Holder.

                   7. Covenants. The Company covenants, so long as this Note
shall be outstanding and unless the Holder shall otherwise consent in writing,
that:

                  (a) Financial Statements, Reports, etc. So long as this
Convertible Note shall remain outstanding and the Company is subject to the
filing requirements of Section 13(a), 13(c) or 15(d) of the Securities Exchange
Act of 1934, as amended (the 'Exchange Act'), the Company will transmit or cause
to be transmitted to Holder, promptly after the same are sent or become publicly
available, copies of any and all financial statements and reports which are made
available to its stockholders and all periodic and other reports, proxy
statements, registration statements and other materials filed by it with the
Securities and Exchange Commission, or any other governmental authority
succeeding to any or all of the functions of said commission, or any national
securities exchange, as the case may be. If the Company is not subject to filing
requirements, the Company will transmit or cause to be transmitted to the Holder
annual and quarterly reports containing audited annual financial statements and
related notes thereto and unaudited quarterly financial statements.

                  (b) Corporate Existence. The Company shall, and shall cause

this Note, shall mean the earlier of ninety (90) days from its due date or
invoice date, as the case may be, or the date upon which such obligee commences
and action or proceeding to recover such amount), provided, however, that the
Company shall not be required to pay and discharge or to cause to be paid and
discharged any such tax, assessment, charge, levy or claim so long as the
validity or amount



                                      -6-

otherwise) or any other interest in, any other Person, except for Permitted

                  (g) Payments. The Company shall not, and shall not permit any
of its Subsidiaries to, declare or pay, directly or indirectly, any dividends or
make any other distribution or payment, whether in cash, property, securities or

otherwise) any shares of capital stock (or any options, warrants, rights or

value any shares of its capital stock or warrants or options therefor now or

                  (h) Disposition of Assets. The Company shall not, and shall

related transactions is approved by a majority of the Board of Directors of the
Company (including a majority of the disinterested directors), which approval is

Company, declare this Note due and payable, whereupon the same shall be due and
payable without presentment, demand, protest or other notice of any kind, all of
which are hereby expressly waived, provided, however, that if an event specified

                  10.      Investment Representation.

                  10.1 Holder hereby acknowledges that this Note is not being
registered (i) under the Act on the ground that the issuance of the Note is
exempt from registration under Section 4(2) of the Act as not involving any
public offering or (ii) under any applicable state securities law because the
issuance of this Note does not involve any public offering; and that the
Company's reliance on the Section 4(2) exemption of the Act and under applicable
state securities laws is predicated in part on the representations hereby made
to the Company by the Holder that it is acquiring this Note for investment for
its own account, with no present intention of dividing its participation with
others or reselling or otherwise distributing the



                                      -9-

same, provided, nevertheless, that the disposition of its property shall at
all times be within its control.

                  10.2 Holder hereby agrees that it will not sell or transfer
all or any part of this Note unless and until it shall first have given notice
to the Company describing such sale or transfer and furnished to the Company
either (a) an opinion, reasonably satisfactory to counsel for the Company, of
counsel (skilled in securities matters, selected by the Holder and
reasonably satisfactory to the Company) to the effect that the proposed sale or
transfer may be made without registration under the Act or (b) an interpretive
letter from the Securities and Exchange Commission to the effect that no
enforcement action will be recommended if the proposed sale or transfer is made
without registration under the Act.

                  10.3 The Company may refuse to recognize a transfer of this
Note on its books should a holder attempt to transfer this Note otherwise than
in compliance with this Section 10.

          respect to the Senior Indebtedness; (B) an acceleration of the Senior
          Indebtedness; or (C) the occurrence of an event of the type described
          in Section 5 hereof, provided further, that a Blockage Event may be
          deemed to occur only once for each 360 day period.

                  (d) At any time there exists a Blockage Event, (i) the Company
shall not, directly or indirectly, make any payment of any part of this
Convertible Note, (ii) the Holder hereof shall not demand or accept from the
Company or any other Person any such payment or cancel, set off or otherwise
discharge any part of the indebtedness represented by this Convertible Note, and
(iii) neither the Company nor the Holder hereof shall otherwise take or permit
any action prejudicial to or inconsistent with the priority position of any
holder of Senior Indebtedness over the Holder of this Convertible Note.
Notwithstanding the foregoing, or any other provision of this Convertible Note
to the contrary, the occurrence and continuance of a Blockage Event shall not
limit or in any other manner affect the exercise of the Holder's conversion
rights pursuant to Section 6.

                  (e) Any holder of Senior Indebtedness is hereby authorized to
demand specific performance of this Convertible Note, whether or not the Company
shall have complied with the provisions hereof applicable to it, at any time
when the Holder hereof shall have failed to comply with any provision hereof
applicable to him. The Holder hereby irrevocably waives any defense based on the
adequacy of a remedy at law which might be asserted as a bar to the remedy of
specific performance hereof in any action brought therefor by any holder of
Senior Indebtedness. The Holder further (i) waives presentment, demand, notice
and protest in connection with all negotiable instruments evidencing Senior
Indebtedness, notice of any loan made, extension granted or other action taken
in reliance hereon and all demands and notices of every kind in connection with
this Convertible Note or Senior Indebtedness; and (ii) assents to any renewal,
extension or postponement of the time of payment of Senior Indebtedness or any
other indulgence with respect thereto, to any substitution, exchange or release
of collateral therefor and to the addition or release of any Person primarily or
secondarily liable thereon.

                  (f) The Company and the Holder shall execute and deliver to
any holder of Senior Indebtedness such further instruments and shall take such
further action as such holder of Senior Indebtedness may at any time or times
reasonably request in order to evidence the subordination of the obligations
hereunder and to otherwise carry out the provisions and intent of this
Convertible Note.

                  (g) No right of any holder of Senior Indebtedness to enforce
the subordination of the obligations shall be impaired by any act or failure to
act by the Company or the Holder or by their failure to comply with this
Convertible Note or any other agreement or document evidencing, related to or
securing the obligations hereunder. Without in any way limiting the generality
of the preceding sentence, the holders of Senior Indebtedness may, at any time
and from time to time, without the consent of or notice to the Holder, without
incurring responsibility to the Holder and without impairing or releasing the
subordination provided in this Convertible Note or the obligations of the holder
hereof to the



                                      -4-



<PAGE>


holders of Senior Indebtedness, do any one or more of the following: (i)
change the manner, place or terms of payment of, or renew or alter, any Senior
Indebtedness, or otherwise amend or supplement in any manner, any Senior
Indebtedness or any instrument evidencing the same or any agreement under which
Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise
deal with any property pledged, mortgaged or otherwise securing any Senior
Indebtedness; (iii) release any Person or entity liable in any manner for the
collection of any Senior Indebtedness; and (iv) exercise or refrain from
exercising any rights against the Company or any other Person or entity.

                  (h) In the event that the Company shall make any payment or
prepayment to the Holder on account of the obligations under this Convertible
Note which is prohibited by this Section 4, such payment shall be held by the
Holder, in trust for the benefit of, and shall be paid forthwith over and
delivered to, the holders of Senior Indebtedness (pro rata as to each of such
holders on the basis of the respective amounts and priorities of Senior
Indebtedness held by them) to the extent necessary to pay all Senior
Indebtedness due to such holders in full in accordance with its terms (whether
or not such Senior Indebtedness is due and owing), after giving effect to any
concurrent payment or distribution to or for the holders of such Senior
Indebtedness.

                  (i) After all Senior Indebtedness indefeasibly is paid in full
and until the obligations under this Convertible Note are paid in full, the
Holder shall be subrogated to the rights of holders of Senior Indebtedness to
the extent that distributions otherwise payable to the Holder have been applied
to the payment of Senior Indebtedness. For purposes of such subrogation, no
payments or distributions to holders of such Senior Indebtedness of any cash,
property or securities to which the Holder would be entitled except for the
provisions of this Section 4 and no payment over pursuant to the provisions of
this Section 4 to holders of such Senior Indebtedness by the Holder, shall, as
between the Company, its creditors, other than holders of such Senior
Indebtedness, and the Holder, be deemed to be a payment by the Company to or on
account of such Senior Indebtedness, it being understood that the provisions of
this Section 4 are solely for the purpose of defining the relative rights of the
holders of such Senior Indebtedness, on the one hand, and the Holder hereof, on
the other hand.

                  5. Primacy of Senior Indebtedness Claims as Against the
Holder. In any insolvency, receivership, bankruptcy, dissolution, liquidation or
reorganization proceeding, or in any other proceeding, whether voluntary or
involuntary, by or against the Company under any bankruptcy or insolvency law or
laws relating to relief of debtors, to compositions, extensions, or
readjustments of indebtedness:

                  (a) the claims of any holders of Senior Indebtedness against
         the Company shall be paid indefeasibly in full in cash before any
         payment is made to the Holder of this Convertible Note;


                                      -5-



<PAGE>



                  (b) until all Senior Indebtedness is indefeasibly paid in full
         any distribution to which the Holder would be entitled but for this
         Section 5 shall be made to holders of Senior Indebtedness; and

                  (c) the holders of Senior Indebtedness shall have the right to
enforce, collect and receive every such payment or distribution and give
acquittance therefor. In furtherance of the foregoing, in the event that the
Company shall file or have filed against it a petition under any chapter of
Title 11 of the United States Code or any comparable statute, with the result
that the Company is excused from the obligation to pay all or any part of the
amount otherwise payable in respect of the Senior Indebtedness during the period
subsequent to the commencement of such proceedings, the Holder agrees that all
or such part of such amount shall be payable out of, and to that extent diminish
and be at the expense of, the Holder's reorganization dividends or other
distributions in respect of any claim filed by it as a creditor or interest
holder. In the event the holders of Senior Indebtedness receive amounts in
excess of payment in full (in cash) of amounts outstanding in respect of Senior
Indebtedness (without giving effect to whether claims in respect of the Senior
Indebtedness are allowed in any insolvency proceeding), the holders of the
Senior Indebtedness shall pay such excess amounts to the Holder.

                  6. Conversion. The Holder of this Convertible Note will have
the right, exercisable at any time on or before the Maturity Date, by notice to
the Company at its principal office, at his option to convert this Convertible
Note at the principal amount hereof (or any portion hereof that is an integral
multiple of $1,000) into 500 shares of the common stock, par value $.10 per
share, of the Company (the 'Common Stock') for each $1,000 face amount of this
Convertible Note, representing a conversion price equal to $2.00 per share,
subject to adjustment as set forth below (the 'Conversion Price'). The Company
may at any time, by notice to the Holder, require the conversion of this
Convertible Note in accordance with this Section 6, and the Holder shall
promptly surrender this Convertible Note for conversion following such notice,
provided that the Closing Price for the Common Stock for thirty (30) consecutive
trading days prior to such notice is equal to or greater than $6.00 per share,
subject to adjustment proportionately with any adjustment of the Conversion
Price pursuant to this Section 6.

                  Subject to the right of the Holder on the conversion date to
receive all interest on such Convertible Note accrued through such date of
conversion, no adjustment for interest or dividends will be made upon the
conversion of this Convertible Note. No fractional shares will be issued upon
conversion, but if the conversion results in a fraction, an appropriate amount
will be paid by the Company in cash. This right of conversion shall cease upon
payment in full of all principal and interest and other amounts due in respect
of this Note.

                  The occurrence of any of the following events shall trigger an
adjustment to the Conversion Price and/or the number of shares of Common Stock
into which this Convertible Note shall be converted (the 'Conversion Shares'):


                                      -6-



<PAGE>



                  (a) Recapitalization, Reclassification and Succession. If any
recapitalization of the Company or reclassification of its Common Stock or any
merger or consolidation of the Company into or with a corporation or other
business entity, or the sale or transfer of all or substantially all of the
Company's assets or of any successor corporation's assets to any other
corporation or business entity (any such corporation or other business entity
being included within the meaning of the term 'successor corporation') shall be
effected, at any time while this Convertible Note remains outstanding, then, as
a condition of such recapitalization, reclassification, merger, consolidation,
sale or transfer, lawful and adequate provision shall be made whereby the Holder
of this Convertible Note thereafter shall have the right to receive upon the
conversion hereof as provided in this Section 6 and in lieu of the shares of
Common Stock immediately theretofore issuable upon the conversion of this
Convertible Note, such shares of capital stock, securities or other property as
may be issued or payable with respect to or in exchange for a number of
outstanding shares of Common Stock equal to the number of shares of Common Stock
immediately theretofore issuable upon the conversion of this Convertible Note
had such recapitalization, reclassification, merger, consolidation, sale or
transfer not taken place, and in each such case, the terms of this Convertible
Note shall be applicable to the shares of stock or other securities or property
receivable upon the conversion of this Convertible Note after such consummation.

                  (b) Subdivision or Combination of Shares. If the Company at
any time while this Convertible Note remains outstanding shall subdivide or
combine its Common Stock, the Conversion Price and the Conversion Shares shall
be proportionately adjusted.

                  (c) Stock Dividends and Distributions. If the Company at any
time while this Convertible Note is outstanding shall issue or pay the holders
of its Common Stock, or take a record of the holders of its Common Stock for the
purpose of entitling them to receive, a dividend payable in, or other
distribution of, Common Stock, then (i) the Conversion Price shall be adjusted
in accordance with Section 6(e) and (ii) the number of Conversion Shares shall
be adjusted to the number of shares of Common Stock that Holder would have owned
immediately following such action had this Convertible Note been converted
immediately prior thereto.

                  (d) Certain Stock Issuances. If at any time after the date 
of issuance of this Convertible Note, the Company shall issue or sell, or fix 
a record date for the purposes of entitling holders of its Common Stock to
receive, (i) Common Stock or (ii) rights, options or warrants entitling
the holders thereof to subscribe for or purchase Common Stock (or securities
convertible or exchangeable into or exercisable for Common Stock), in any such
case, at a price per share (or having a conversion, exchange or exercise price
per share) that is less than the lowest Closing Price during the twenty (20)
trading days immediately preceding the date of such issuance or sale or such
record date then, immediately after the date of such issuance or sale or on such
record date, (A) the Conversion Price shall be adjusted in accordance with
Section 6(e) and (B) the number of Conversion Shares shall be adjusted to that
number determined by multiplying the number of Conversion Shares immediately
before the date of such issuance or sale or such record date

                                      -7-



<PAGE>


by a fraction, the denominator of which will be the number of shares of Common
Stock outstanding on such date plus the number of shares of Common Stock that
the aggregate offering price of the total number of shares so offered for
subscription or purchase (or the aggregate initial conversion price, exchange
price or exercise price of the convertible securities or exchangeable securities
or rights, options or warrants, as the case may be, so offered) would purchase
at such Closing Price, and the numerator of which will be the number of shares
of Common Stock outstanding on such date plus the number of additional shares of
Common Stock offered for subscription or purchase (or into which the convertible
or exchangeable securities or rights, options or warrants so offered are
initially convertible or exchangeable or exercisable, as the case may be).

                  If the Company shall, at any time after the date of issuance
of this Convertible Note distribute to all holders of its Common Stock any
shares of capital stock of the Company (other than Common Stock) or evidences of
its indebtedness or assets (excluding cash dividends or distributions paid from
retained earnings or current year's or prior year's earnings of the Company) or
rights or warrants to subscribe for or purchase any of its securities (excluding
those referred to in the immediately preceding paragraph)(any of the foregoing
being hereinafter in this paragraph called the 'Distributed Interests'), then in
each such case, the Company shall reserve shares or other units of such
Distributed Interests for distribution to the Holder upon conversion of this
Convertible Note so that, in addition to the shares of the Common Stock to which
such Holder is entitled, such Holder will receive upon such exercise the amount
and kind of such Distributed Interests which such Holder would have received
if the Holder had, immediately prior to the record date for the distribution of
the Distributed Interests, converted this Convertible Note.

                  (e) Conversion Price Adjustment. Whenever the number of
Conversion Shares is adjusted, as herein provided, the Conversion Price payable
upon the conversion of this Convertible Note shall be adjusted to that price
determined by multiplying the Conversion Price immediately prior to such
adjustment by a fraction (i) the numerator of which shall be the number of
Conversion Shares immediately prior to such adjustment, and (ii) the denominator
of which shall be the number of Conversion Shares immediately thereafter.

                  (f) Certain Shares Excluded. The number of shares of Common
Stock outstanding at any given time for purposes of the adjustments set forth in
this Section 6 shall exclude any shares then directly or indirectly held in the
treasury of the Company.

                  (g) Deferral and Cumulation of De Minimis Adjustments. The
Company shall not be required to make any adjustment pursuant to this Section 6
if the amount of such adjustment should be less than one percent (1%) of the
Conversion Price in effect immediately before the event that would otherwise
have given rise to such adjustment. In such case, however, any adjustment that
would otherwise have been required to be made shall be made at the time of and
together with the next subsequent adjustment which, together with any adjustment
or adjustments so carried forward, shall amount to not less than



                                      -8-



<PAGE>

one percent (1%) of the Conversion Price in effect immediately before the event
giving rise to such next subsequent adjustment.


                  (h) Duration of Adjustment. Following each computation or
readjustment provided in this Section 6, the new adjusted Conversion Price and
number of Conversion Shares shall remain in effect until a further computation
or readjustment thereof is required.

                  The Company shall deliver a certificate or certificates for
shares of its Common Stock issuable on conversion of this Convertible Note as
soon as practicable after surrender of this Convertible Note for conversion, but
the Person or Persons to whom such certificates are issuable shall be considered
the holder of record of the shares of Common Stock from the time this
Convertible Note is surrendered. Except as described above, this Convertible
Note is not otherwise convertible into shares of Common Stock.

                  7. Notices to Holders.

                  (a) Notice of Record Date. In case:

                  (i) the Company shall take a record of the holders of its
          Common Stock (or other stock or securities at the time receivable upon
          the conversion of this Convertible Note) for the purpose of entitling
          them to receive any dividend or other distribution, or any right to
          subscribe for or purchase any shares of stock of any class or any
          other securities, or to receive any other right; or

                  (ii) of any capital reorganization of the Company, any
          reclassification of the capital stock of the Company, any
          consolidation with or merger of the Company into another corporation,
          or any conveyance of all or substantially all of the assets of the
          Company to another corporation; or

                  (iii) of any voluntary dissolution, liquidation or winding-up
          of the Company;

then, and in each such case, the Company will mail or cause to be mailed to the
Holder hereof at the time outstanding a notice specifying, as the case may be,
(i) the date on which a record is to be taken for the purpose of such dividend,
distribution or right, and stating the amount and character of such dividend,
distribution or right, or (ii) the date on which such reorganization,
reclassification, consolidation, merger, conveyance, dissolution, liquidation or
winding-up is to take place, and the time, if any, is to be fixed, as of which
the holders of record of Common Stock (or such stock or securities at the time
receivable upon the conversion of this Convertible Note) shall be entitled to
exchange their shares of Common Stock (or such other stock or securities) for
securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, conveyance, dissolution, liquidation or
winding-up. Such notice shall be mailed at least 30 days prior to the record
date therein specified, or if no record date shall have been specified therein,
at least 30 days prior to such other specified date.

                  (b) Notice of Adjustments. Whenever the Conversion Price or
the number of Conversion Shares shall be adjusted pursuant to Section 6 hereof,
the Company shall promptly make a certificate signed by its President or a Vice
President and by its Treasurer or Assistant Treasurer or its Secretary or
Assistant Secretary, setting forth in reasonable detail, the event requiring the
adjustment, the amount of the adjustment, the method by which such adjustment
was calculated and the number of Conversion Shares and the Conversion Price
after giving effect to such adjustment, and shall promptly cause copies of such
certificates to be mailed (by first class mail postage prepaid) to the Holder of
this Convertible Note.

                  8. Covenants. The Company covenants, so long as this
Convertible Note shall be outstanding and unless the Holder shall otherwise
consent in writing, that:

Convertible Note shall remain outstanding and the Company is subject to the
filing requirements of Section 13(a), 13(c) or 15(d) of the Securities Exchange

Securities and Exchange Commission, or any other governmental authority
succeeding to any or all of the functions of said commission, or any national
securities exchange, as the case may be. If the Company is not subject to filing
requirements, the Company will transmit or cause to be transmitted to the Holder
annual and quarterly reports containing audited annual financial statements and
related notes thereto and unaudited quarterly financial statements.

                  (b) Registration of Shares. The Company shall file a
registration statement with the Securities and Exchange Commission under the

the Company's common stock, par value $.10 per shares, issuable pursuant hereto

its Subsidiaries to, pay and discharge all taxes, assessments and governmental

date or invoice date, as the case may be, or the date upon which such obligee
commences and action or proceeding to recover such amount), provided, however,
that the Company shall not be required to pay and discharge or to cause to be

property, the making of any investment, the giving of any guarantee or the

transactions among the Company and any wholly-owned Subsidiary) unless (i) such

Board of Directors of the Company (including a majority of the disinterested

                  (iii) any obligation of the Company for the payment of

                  11. Investment Representation.

                  11.1 Holder hereby acknowledges that this Convertible Note and
the Conversion Shares are not being registered (i) under the Act on the ground
that the issuance of the Convertible Note is exempt from registration under
Section 4(2) of the Act as not involving any public offering or (ii) under any
applicable state securities law because the issuance of this Convertible Note
does not involve any public offering; and that the Company's reliance on the
Section 4(2) exemption of the Act and under applicable state securities laws is
predicated in part on the representations hereby made to the Company by the
Holder that it is acquiring this Convertible Note for investment for its own
account, with no present intention of dividing its participation with others or
reselling or otherwise distributing the same, provided, nevertheless, that the
disposition of its property shall at all times be within its control.

                  11.2 Holder hereby agrees that it will not sell or transfer
all or any part of this Convertible Note and/or Conversion Shares unless and
until it shall first have given notice to the Company describing such sale or
transfer and furnished to the Company either (a) an opinion, reasonably
satisfactory to counsel for the Company, of counsel (skilled in securities
matters, selected by the Holder and reasonably satisfactory to the Company) to
the effect that the proposed sale or transfer may be made without registration
under the Act or (b) an interpretive letter from the Securities and Exchange
Commission to the effect that no enforcement action will be recommended if the
proposed sale or transfer is made without registration under the Act.

                  11.3 If, at the time of issuance of the Conversion Shares, no
registration statement is in effect with respect to such shares under applicable
provisions of the Act, the Company may at its election require that Holder
provide the Company with written reconfirmation of the Holder's investment
intent and that any stock certificate delivered to the Holder upon conversion of
this Convertible Note shall bear legends reading substantially as follows:

         'TRANSFER OF THE SHARES REPRESENTED BY THIS CERTIFICATE IS

         REQUIRED UNDER SAID ACT.'

2.  Disposition of Warrant Stock and Warrant.

     (a) Holder hereby acknowledges that this Warrant and any Warrant Stock
purchased hereto are not being registered (i) under the Act on the ground that
the issuance of this Warrant is exempt from registration under Section 4(2) of
the Act as not involving any public offering or (ii) under any applicable state
securities law because the issuance of this Warrant does not involve any public
offering; and that the Company's reliance on the Section 4(2) exemption of the
Act and under applicable state securities laws is predicated in part on the
representations hereby made to the Company by the Holder that it is acquiring
this Warrant for investment for its own account, with no present intention of
dividing its participation with others or reselling or otherwise

                                      -2-

<PAGE>


distributing the same, subject, nevertheless, to any requirement of law that the
disposition of its property shall at all times be within its control.

     Holder hereby agrees that it will not sell or transfer all or any part of
this Warrant and/or Warrant Stock unless and until it shall first have given
notice to the Company describing such sale or transfer and furnished to the
Company either (i) an opinion, reasonably satisfactory to counsel for the
Company, of counsel (skilled in securities matters, selected by the Holder and
reasonably satisfactory to the Company) to the effect that the proposed sale or
transfer may be made without registration under the Act, or (ii) an interpretive
letter from the Securities and Exchange Commission to the effect that no
enforcement action will be recommended if the proposed sale or transfer is made
without registration under the Act.

     (b) If, at the time of issuance of the shares issuable upon exercise of
this Warrant, no registration statement is in effect with respect to such shares
under applicable provisions of the Act, the Company may at its election require
that the Holder provide the Company with written reconfirmation of the Holder's
investment intent and that any stock certificate delivered to the Holder of a
surrendered Warrant shall bear legends reading substantially as follows:

     'TRANSFER OF THE SHARES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO
     CERTAIN RESTRICTIONS SET FORTH IN THE WARRANT PURSUANT TO WHICH THESE
     SHARES WERE PURCHASED FROM THE COMPANY. COPIES OF THOSE RESTRICTIONS ARE ON
     FILE AT THE PRINCIPAL OFFICES OF THE COMPANY, AND NO TRANSFER OF SUCH
     SHARES OR OF THIS CERTIFICATE, OR OF ANY SHARES OR OTHER SECURITIES (OR
     CERTIFICATES THEREFOR) ISSUED IN EXCHANGE FOR OR IN RESPECT OF SUCH SHARES,
     SHALL BE EFFECTIVE UNLESS AND UNTIL THE TERMS AND CONDITIONS THEREIN SET
     FORTH SHALL HAVE BEEN COMPLIED WITH.'

     'THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
     THE SECURITIES ACT OF 1933, AND MAY NOT BE SOLD, TRANSFERRED, PLEDGED OR
     OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT
     UNDER THE SECURITIES ACT OF 1933 OR AN OPINION OF COUNSEL SATISFACTORY TO
     THE ISSUER OF THIS CERTIFICATE THAT REGISTRATION IS NOT REQUIRED UNDER SAID
     ACT.'

In addition, so long as the foregoing legend may remain on any stock certificate
delivered to the Holder, the Company may maintain appropriate 'stop transfer'
orders with respect

                                      -3-

<PAGE>


to such certificates and the shares represented thereby on its books and records
and with those to whom it may delegate registrar and transfer functions.

3.  Reservation of Shares.

     The Company hereby agrees that at all times there shall be reserved for
issuance upon the exercise of this Warrant such number of shares of its Common
Stock as shall be required for issuance upon exercise of this Warrant. The
Company further agrees that all shares which may be issued upon the exercise of
the rights represented by this Warrant will, upon issuance, be validly issued,
fully paid and non-assessable, free from all taxes, liens and charges with
respect to the issuance thereof other than taxes, if any, in respect of any
transfer occurring contemporaneously with such issuance and other than transfer
restrictions imposed by federal and state securities laws.

4.  Capital Adjustments.

     This Warrant is subject to the following further provisions:

     (a) Recapitalization, Reclassification and Succession. If any
recapitalization of the Company or reclassification of its Common Stock or any
merger or consolidation of the Company into or with a corporation or other
business entity, or the sale or transfer of all or substantially all of the
Company's assets or of any successor corporation's assets to any other
corporation or business entity (any such corporation or other business entity
being included within the meaning of the term 'successor corporation') shall be
effected, at any time while this Warrant remains outstanding and unexpired,
then, as a condition of such recapitalization, reclassification, merger,
consolidation, sale or transfer, lawful and adequate provision shall be made
whereby the Holder of this Warrant thereafter shall have the right to receive
upon the exercise hereof as provided in Section 1 and in lieu of the shares of
Common Stock immediately theretofore issuable upon the exercise of this Warrant,
such shares of capital stock, securities or other property as may be issued or
payable with respect to or in exchange for a number of outstanding shares of
Common Stock equal to the number of shares of Common Stock immediately
theretofore issuable upon the exercise of this Warrant had such
recapitalization, reclassification, merger, consolidation, sale or transfer not
taken place, and in each such case, the terms of this Warrant shall be
applicable to the shares of stock or other securities or property receivable
upon the exercise of this Warrant after such consummation.

                                      -4-

<PAGE>


     (b) Subdivision or Combination of Shares. If the Company at any time while
this Warrant remains outstanding and unexpired shall subdivide or combine its
Common Stock, the number of shares of Warrant Stock purchasable upon exercise of
this Warrant and the Warrant Price shall be proportionately adjusted.

     (c) Stock Dividends and Distributions. If the Company at any time while
this Warrant is outstanding and unexpired shall issue or pay the holders of its
Common Stock, or take a record of the holders of its Common Stock for the
purpose of entitling them to receive, a dividend payable in, or other
distribution of, Common Stock, then (i) the Warrant Price shall be adjusted in
accordance with Section 4(e) and (ii) the number of shares of Warrant Stock
purchasable upon exercise of this Warrant shall be adjusted to the number of
shares of Common Stock that Holder would have owned immediately following such
action had this Warrant been exercised immediately prior thereto.


     (d) Stock and Rights Offering to Stockholders. If at any time after the
date of issuance of this Warrant, the Company shall issue or sell, or fix a
record date for the purposes of entitling holders of its Common Stock to
receive, (i) Common Stock or (ii) rights, options or warrants entitling the
holders thereof to subscribe for or purchase Common Stock (or securities
convertible or exchangeable into or exercisable for Common Stock), in any such
case, at a price per share (or having a conversion, exchange or exercise price
per share) that is less than the closing price per share of the Company's Common
Stock on the principal national securities exchange on which the Common Stock is
listed or admitted to trading or, if not listed or traded on any such exchange,
on the National Market System (the 'National Market System') of the National
Association of Securities Dealers Automated Quotations System ('NASDAQ'), or if
not listed or traded on any such exchange or system, the average of the bid and
asked price per share on NASDAQ or, if such quotations are not available, the
fair market value per share of the Company's Common Stock as reasonably
determined by the Board of Directors of the Company (the 'Closing Price') on the
date of such issuance or sale or on such record date then, immediately after the
date of such issuance or sale or on such record date, (x) the Warrant Price
shall be adjusted in accordance with Section 4(e) and (y) the number of shares
of Warrant Stock purchasable upon exercise of this Warrant shall be adjusted to
that number determined by multiplying the number of shares of Warrant Stock
purchasable upon exercise of this Warrant immediately before the date of such
issuance or sale or such record date by a fraction, the denominator of which
will be the number of shares of Common Stock outstanding on such date plus the
number of shares of Common Stock that the

                                      -5-

<PAGE>


aggregate offering price of the total number of shares so offered for
subscription or purchase (or the aggregate initial conversion price, exchange
price or exercise price of the convertible securities or exchangeable securities
or rights, options or warrants, as the case may be, so offered) would purchase
at such Closing Price, and the numerator of which will be the number of shares
of Common Stock outstanding on such date plus the number of additional shares of
Common Stock offered for subscription or purchase (or into which the convertible
or exchangeable securities or rights, options or warrants so offered are
initially convertible or exchangeable or exercisable, as the case may be).

          If the Company shall, at any time after the date of issuance of this
Warrant, distribute to all holders of its Common Stock any shares of capital
stock of the Company (other than Common Stock) or evidences of its indebtedness
or assets (excluding cash dividends or distributions paid from retained earnings
or current year's or prior year's earnings of the Company) or rights or warrants
to subscribe for or purchase any of its securities (excluding those referred to
in the immediately preceding paragraph)(any of the foregoing being hereinafter
in this paragraph called the 'Securities'), then in each such case, the Company
shall reserve shares or other units of such securities for distribution to the
Holder upon exercise of this Warrant so that, in addition to the shares of the
Common Stock to which such Holder is entitled, such Holder will receive upon
such exercise the amount and kind of such Securities which such Holder would
have received if the Holder had, immediately prior to the record date for the
distribution of the Securities, exercised this Warrant.

     (e) Warrant Price Adjustment. Whenever the number of shares of Warrant
Stock purchasable upon exercise of this Warrant is adjusted, as herein provided,
the Warrant Price payable upon the exercise of this Warrant shall be adjusted to
that price determined by multiplying the Warrant Price immediately prior to such
adjustment by a fraction (i) the numerator of which shall be the number of
shares of Warrant Stock purchasable upon exercise of this Warrant immediately
prior to such adjustment, and (ii) the denominator of which shall be the number
of shares of Warrant Stock purchasable upon exercise of this Warrant immediately
thereafter.

     (f) Certain Shares Excluded. The number of shares of Common Stock
outstanding at any given time for purposes of the adjustments set forth in this
Section 4 shall exclude any shares then directly or indirectly held in the
treasury of the Company.

                                      -6-

<PAGE>


     (g) Deferral and Cumulation of De Minimis Adjustments. The Company shall
not be required to make any adjustment pursuant to this Section 4 if the amount
of such adjustment would be less than one percent (1%) of the Warrant Price in
effect immediately before the event that would otherwise have given rise to such
adjustment. In such case, however, any adjustment that would otherwise have been
required to be made shall be made at the time of and together with the next
subsequent adjustment which, together with any adjustment or adjustments so
carried forward, shall amount to not less than one percent (1%) of the Warrant
Price in effect immediately before the event giving rise to such next subsequent
adjustment.

     (h) Duration of Adjustment. Following each computation or readjustment as
provided in this Section 4, the new adjusted Warrant Price and number of shares
of Warrant Stock purchasable upon exercise of this Warrant shall remain in
effect until a further computation or readjustment thereof is required.

5.  Notices to Holders.

     (a) Notice of Record Date. In case:

          (i) the Company shall take a record of the holders of its Common Stock
     (or other stock or securities at the time receivable upon the exercisable
     of this Warrant) for the purpose of entitling them to receive any dividend
     or other distribution, or any right to subscribe for or purchase any shares
     of stock of any class or any other securities, or to receive any other
     right; or

          (ii) of any capital reorganization of the Company, any
     reclassification of the capital stock of the Company, any consolidation
     with or merger of the Company into another corporation, or any conveyance
     of all or substantially all of the assets of the Company to another
     corporation; or

          (iii) of any voluntary dissolution, liquidation or winding-up of the
     Company;

then, and in each such case, the Company will mail or cause to be mailed to the
Holder hereof at the time outstanding a notice specifying, as the case may be,
(i) the date on which a record is to be taken for the purpose of such dividend,
distribution or right, and stating the amount and character of such dividend,
distribution or right, or (ii) the date on which such reorganization,
reclassification, consolidation, merger, conveyance, dissolution, liquidation or
winding-up is to take place, and the time, if any, is to be fixed, as

                                      -7-

of which the holders of record of Common Stock (or such stock or securities at
the time receivable upon the exercise of this Warrant) shall be entitled to

securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, conveyance, dissolution, liquidation or
winding-up. Such notice shall be mailed at least 30 days prior to the record
date therein specified, or if no record date shall have been specified therein,
at least 30 days prior to such other specified date.

     (b) Notice of Adjustment. Whenever any adjustment shall be made pursuant to
Section 4 hereof, the Company shall promptly make a certificate signed by its
Chairman and CEO, its President or a Vice President and by its Treasurer or
Assistant Treasurer or its Secretary or Assistant Secretary, setting forth in
reasonable detail, the event requiring the adjustment, the amount of the
adjustment, the method by which such adjustment was calculated and the Warrant
Price and number of shares of Warrant Stock purchasable upon exercise of this
Warrant after giving effect to such adjustment, and shall promptly cause copies
of such certificates to be mailed (by first class mail, postage prepaid) to the
Holder of this Warrant.

6.  Loss, Theft, Destruction or Mutilation.

     Upon receipt by the Company of evidence satisfactory to it, in the exercise
of its reasonable discretion, of the ownership and the loss, theft, destruction
or mutilation of this Warrant and, in the case of loss, theft or destruction, of
indemnity reasonably satisfactory to the Company and, in the case of mutilation,
upon surrender and cancellation thereof, the Company will execute and deliver in
lieu thereof, without expense to the Holder, a new Warrant of like tenor dated
the date hereof.

7.  Warrant Holder Not a Stockholder.

     The Holder of this Warrant, as such, shall not be entitled by reason of
this Warrant to any rights whatsoever as a stockholder of the Company.

8.  Notices.

     Any notice required or contemplated by this Warrant shall be deemed to have
been duly given if transmitted by registered or certified mail, return receipt
requested, to the Company at 1000 Woodbury Road, Suite 412, Woodbury, New York
11797 Attention: President, or to the Holder at the name and address set forth

                  2. Piggyback Registration Rights.

                  (a) Right to Piggyback. Subject to the last sentence of this
         subsection (a), whenever the Company proposes to register any Shares
         (or securities convertible into or exchangeable or exercisable for
         Shares) under the Securities Act, at any time on or before the
         Expiration Date, for its own account or for the account of Persons
         exercising demand registration rights other than pursuant to Section 3
         below, other than under a Registration Statement on Form S-4, Form S-8
         or any successor form or filed in connection with an exchange offer or
         an offering of securities solely to the Company's existing employees or
         securityholders (a 'Piggyback Registration'), the Company will give
         prompt written notice to Holder of its intention to effect such a
         Registration and will use its best efforts, subject to Section 2(b)
         below, to include in such Piggyback Registration all Registrable
         Securities with respect to which the Company has received written
         requests for inclusion therein within 15 Business Days after the
         receipt of the Company's notice. Except as may otherwise be provided in
         this Agreement, Registrable Securities with respect to which such
         request for Registration has been received will be registered by the
         Company and offered to the public on the same terms and subject to the
         same conditions applicable to the Piggyback Registration to be sold by
         the Company or by the other Persons selling under such Piggyback
         Registration. Notwithstanding the foregoing, the Company shall have the
         right to postpone or withdraw any Registration effected pursuant to
         this Section 2(a).

                  (b) Priority on Piggyback Registrations. If a Piggyback
         Registration relates to an underwritten offering and the managing
         underwriter or underwriters advise the Company in writing that in its
         or their opinion the number of securities proposed to be sold in a
         Piggyback Registration exceeds the number which can be sold in such
         offering within a price range acceptable to the Company or the other
         Persons exercising demand registration rights, the Company will include
         in such Piggyback Registration the number of securities which, in the
         opinion of such underwriter or underwriters, can be sold within such
         price range, which securities shall be allocated as follows: (x) first,
         the securities proposed to be sold by other Persons exercising demand
         registration rights granted on or prior to the date hereof, (y) second,
         Registrable Securities held by Holder and requested to be included in
         such Piggyback Registration, together with any other



                                      -3-




<PAGE>


         securities requested to be included in such Piggyback Registration by
         other holders, pro rata among Holder and the other holders of
         Registrable Securities requested to be included in such Piggyback
         Registration, and (z) third, the securities the Company proposes to
         sell.

                  (c) Underwriting. If a Piggyback Registration for which the
         Company gives notice is for a registered public offering involving an
         underwriting, the Company shall so advise Holder in the notice given
         pursuant to Section 2(a), which notice shall include the name of the
         managing underwriter or underwriters. In such event, the right of
         Holder to Piggyback Registration pursuant to this Section 2 shall be
         conditional upon Holder's participation in such underwriting with
         respect to all of its securities included in such Piggyback
         Registration.

                  3. Demand Registration Rights.

                  (a) Right to Demand. At any time on or before the Expiration
         Date, Holder may make up to two written requests (provided in each case
         Holder has not registered Registrable Securities pursuant to Section 2
         above within 120 days prior to such request) to the Company for
         registration with the Commission under and in accordance with the
         provisions of the Securities Act of not less than $1,000,000 of the
         Registrable Securities (a 'Demand Registration'). Unless expressly
         agreed to by the Holder, no securities of the Company or of any other
         Person other than Registrable Securities shall be included in a Demand
         Registration except pursuant to the exercise of any piggyback
         registration rights granted on or prior to the date hereof.

                  (b) Priority on Demand Registrations. If the managing
         underwriter or underwriters of a Demand Registration (or in the case of
         a Demand Registration not being underwritten, the Holder) advise the
         Company in writing that in its or their opinion the number of
         securities proposed to be sold in such Demand Registration exceeds the
         number which can be sold in such offering, the Company will include in
         such Demand Registration only the number of securities which, in the
         opinion of such underwriter or underwriters (or the Holder, as the case
         may be), can be sold in such offering which securities shall be
         allocated on a pro rata basis among the Registrable Securities and such
         other securities requested to be included in such Demand Registration
         pursuant to the exercise of any piggyback registration rights granted
         on or prior to the date hereof.

                  (c) Selection of Underwriters. If any Demand Registration is
         an underwritten offering, the Holder will select a managing underwriter
         or underwriters to administer the offering which managing underwriter
         or underwriters shall be of nationally recognized standing and shall be
         reasonably acceptable to the Company.

                  4. Registration Procedures. With respect to any Registration
pursuant to the exercise of rights provided by Sections 2 and 3 of this
Agreement, the Company will (subject to Section 11 below) promptly:

                  (a) prepare and file with the Commission a Registration
         Statement (a 'Registration Statement') which includes the Registrable
         Securities and use its best efforts to cause such Registration
         Statement to become effective as promptly as practicable; provided that
         before filing a Registration Statement or any amendments thereto of any
         Prospectus, the Company will furnish to one counsel selected by the
         Holder and the underwriters, if any, draft copies of all such documents
         proposed to be filed at least 5 business days prior thereto, which
         documents will be subject to the reasonable review of such counsel and
         underwriters, and the Company will not file any Registration Statement
         or amendment thereto or any Prospectus to which Holder shall reasonably
         object (provided that nothing herein shall prevent the Company from
         making a timely filing of any report required to be filed by it
         pursuant to the Exchange Act in such form as it determines is
         appropriate) and will notify Holder of any stop order issued or
         threatened by the Commission in connection therewith and take all
         reasonable actions required to prevent the entry of such stop order or
         to remove it if entered;

                  (b) prepare and file with the Commission such amendments and
         post-effective amendments to the Registration Statement as may be
         necessary to keep the Registration Statement effective for a period of
         not less than four months (or such shorter period which will terminate
         when all Registrable Securities covered by such Registration Statement
         have been sold or withdrawn, but not prior to the expiration of any
         applicable period referred to in Section 4(3) of the Securities Act and
         Rule 174 thereunder, if applicable); cause the Prospectus to be
         supplemented by any required Prospectus supplement, and as so
         supplemented to be filed pursuant to Rule 424 under the Securities Act;
         and comply with the provisions of the Securities Act applicable to it
         with respect to the disposition of all securities covered by such
         Registration Statement during the applicable period in accordance with
         the intended methods of disposition by the sellers thereof set forth in
         such Registration Statement or Prospectus supplement;

                  (c) furnish to Holder and the underwriter or underwriters, if
         any, at least one signed copy of the Registration Statement and any
         post-effective amendment thereto, upon request, and such number of
         conformed copies thereof and such number of copies of the Prospectus
         (including each preliminary Prospectus), and any documents incorporated
         by reference therein, as Holder or underwriter may reasonably request
         in order to facilitate the disposition of the Registrable Securities
         being sold by Holder (it being understood that the Company consents to
         the use of the Prospectus by Holder and the underwriter or
         underwriters, if any, in connection with the offering and sale of the
         Registrable Securities covered by the Prospectus);

                                      -5-




<PAGE>




                  (d) notify Holder at any time when a Prospectus relating to
         Registrable Securities is required to be delivered under the Securities
         Act, when the Company becomes aware of the happening of any event as a
         result of which the Prospectus included in such Registration Statement
         (as then in effect) contains any untrue statement of a material fact or
         omits to state a material fact necessary to make the statements therein
         (in the case of the Prospectus or any preliminary Prospectus, in light
         of the circumstances under which they were made) not misleading and, as
         promptly as practicable thereafter, prepare and file with the
         Commission and make available a supplement or amendment to such
         Prospectus so that, as thereafter delivered to the purchasers of such
         Registrable Securities, such Prospectus will not contain any untrue
         statement of a material fact or omit to state a material fact necessary
         to make the statements therein, in light of the circumstances under
         which they were made, not misleading;

                  (e) use its best efforts to cause all Registrable Securities
         to be listed, by the date such Registrable Securities cease to be
         Registrable Securities as a result of Registration or otherwise, on
         each securities exchange or national quotation system on which the
         Shares are then listed or proposed to be listed, if any;

                  (f) make generally available to its security holders an
         earnings statement satisfying the provisions of Section 11(a) of the
         Securities Act no later than 45 days after the end of the 12-month
         period beginning with the first day of the Company's first fiscal
         quarter commencing after the effective date of the Registration
         Statement, which earnings statement shall cover said 12-month period;
         provided, however, that in the event that the first day of the
         Company's first fiscal quarter commencing after the effective date of
         the Registration Statement shall also be the first day of the Company's
         fiscal year, such earnings statement shall be made generally available
         no later than 90 days after the end of such 12-month period;

                  (g) use its best efforts to obtain the withdrawal of any order
         suspending the effectiveness of the Registration Statement at the
         earliest possible moment;

                  (h) if requested by the managing underwriter or underwriters
         or Holder promptly incorporate in a Prospectus supplement or
         post-effective amendment such information as the managing underwriter
         or underwriters or Holder requests to be included therein with respect
         to the number of Registrable Securities being sold by Holder to such
         underwriter or underwriters, the purchase price being paid therefor by
         such underwriter or underwriters and with respect to any other terms of
         the underwritten offering of the Registrable Securities to be sold in
         such offering; and promptly make all required filings of such
         Prospectus supplement or post-effective amendment;


                                      -6-




<PAGE>



                  (i) as promptly as practicable after filing with the
         Commission of any document which is incorporated by reference into a
         Registration Statement, deliver a copy of such document to Holder;

                  (j) on or prior to the date on which the Registration
         Statement is declared effective, use its best efforts to register or
         qualify, and cooperate with the Holder, the underwriter or
         underwriters, if any, and their counsel, in connection with the
         registration or qualification of the Registrable Securities covered by
         the Registration Statement for offer and sale under the securities or
         blue sky laws of each state and other jurisdiction of the United States
         as Holder or underwriter reasonably requests in writing, to use its
         best efforts to keep each such registration or qualification effective,
         including through new filings, or amendments or renewals, during the
         period such Registration Statement is required to be kept effective
         pursuant to Section 4(b) hereof and to do any and all other acts or
         things necessary or advisable to permit the disposition in all such
         jurisdictions of the Registrable Securities covered by the applicable
         Registration Statement;

                  (k) cooperate with Holder and the managing underwriter or
         underwriters, if any, to facilitate the timely preparation and delivery
         of certificates (not bearing any restrictive legends) representing
         Registrable Securities to be sold under the Registration Statement and
         enable such securities to be in such denominations and registered in
         such names as the managing underwriter or underwriters, if any, or
         Holder may request;

                  (l) use its best efforts to cause the Registrable Securities
         covered by the Registration Statement to be registered with or approved
         by such other governmental agencies or authorities within the United
         States as may be necessary to enable Holder thereof or the underwriter
         or underwriters, if any, to consummate the disposition of such
         Registrable Securities;

                  (m) enter into such customary agreements (including an
         underwriting agreement in customary form) and take all such other
         actions as Holder or the underwriters retained by Holder, if any,
         reasonably request in order to expedite or facilitate the disposition
         of such Registrable Securities;

                  (n) make available for inspection by Holder, any underwriter
         participating in any disposition pursuant to such Registration
         Statement, and any attorney, accountant or other agent retained by any
         such seller or underwriter (collectively, the 'Inspectors'), all
         financial and other records, pertinent corporate documents and
         properties of the Company and its direct and indirect subsidiaries
         (collectively, the 'Records') as shall be reasonably necessary to
         enable them to exercise their due diligence reasonably, and cause the
         Company's officers, directors and employees to supply all information
         reasonably requested by any such Inspectors in connection with such
         Registration Statement; provided, that the


                                      -7-




<PAGE>


         Records which the Company determines, in good faith, to be confidential
         and which it notifies the Inspectors are confidential shall not be
         disclosed to the Inspectors unless (x) the disclosure of such Records
         is necessary to avoid or correct a misstatement or omission in the
         Registration Statement or (y) the release of such Records is ordered
         pursuant to a subpoena or other order from a court of competent
         jurisdiction; provided, however, that any decision not to disclose
         information pursuant to clause (x) shall be made after consultation
         with counsel for the Company, and Holder agrees that it will, upon
         learning that disclosure of such Records is sought in a court of
         competent jurisdiction, give notice to the Company and allow the
         Company, at the Company's expense, to undertake appropriate action to
         prevent disclosure of the Records deemed confidential; and

                  (o) use its best efforts to obtain a cold comfort letter from
         the Company's independent public accountants and an opinion of outside
         counsel to the Company, each in customary form and covering such
         matters of the type customarily covered by cold comfort letters or
         opinions of counsel, as the case may be, as the Holder reasonably
         requests.

                  Holder, upon receipt of any notice from the Company of the
happening of any event of the kind described in Section 4(d), will forthwith
discontinue disposition of the Registrable Securities until Holder's receipt of
the copies of the supplemented or amended Prospectus contemplated by Section
4(d) or until it is advised in writing (the 'Advice') by the Company that the
use of the Prospectus may be resumed, and has received copies of any additional
or supplemental filings which are incorporated by reference in the Prospectus,
and, if so directed by the Company, Holder will, or will request the managing
underwriter or underwriters, if any, to deliver to the Company all copies, other
than permanent file copies then in Holder's possession, of the Prospectus
covering such Registrable Securities at the time of receipt of such notice. In
the event the Company shall give any such notice, the time period mentioned in
Section 4(b) shall be extended by the number of business days during the period
from and including the date of the giving of such notice to and including the
date when Holder shall have received the copies of the supplemented or amended
Prospectus contemplated by Section 4(d) or the Advice.

                  Holder shall furnish to the Company such information regarding
the Registrable Securities held by it and the intended method of disposition
thereof and other information concerning the Holder as the Company shall
reasonably request and as shall be required in connection with the Registration
Statement to be filed by the Company.

                  5. Holdback Arrangements.

                  (a) Restrictions on Public Sale by Holder of Registrable
         Securities. To the extent not inconsistent with applicable law, Holder
         agrees not to effect any public sale or distribution of the securities
         being registered or a similar security of the Company, or any
         securities convertible into or exchangeable or exercisable



                                      -8-




<PAGE>


         for such securities, including a sale pursuant to Rule 144 or Rule 144A
         under the Securities Act, during the 14 days prior to, and during and
         not exceeding 180 days after the effective date of a Registration
         Statement relating to an underwritten Registration, as may be
         reasonably requested by the managing underwriter or underwriters,
         except as part of such Registration Statement.

                  (b) Restrictions on Public Sale by the Company. The Company
         agrees (x) not to effect any public sale or distribution of any
         securities similar to those being registered, or any securities
         convertible into or exchangeable or exercisable for such securities
         (other than any such sale or distribution of such securities in
         connection with any merger or consolidation involving the Company or a
         subsidiary thereof or the acquisition by the Company or a subsidiary
         thereof of the capital equity or substantially all of the assets of any
         other Person or with respect to any employee benefit or stock plan),
         during the 14 days prior to, and during such period not exceeding 180
         days after the effective date of any Registration Statement except as
         part of such Registration Statement; and (y) that any agreement entered
         into after the date of this Agreement pursuant to which the Company
         issues or agrees to issue any privately placed securities (which
         securities shall be subject to the provisions of Section 2(b)) shall
         contain a provision under which holders of such securities agree not to
         effect any public sale or distribution of any such securities during
         the period described in (x) above, in each case including a sale
         pursuant to Rule 144 or Rule 144A under the Securities Act (except as
         part of any such registration, if permitted); provided, however, that
         the provision of this Section 5(b) shall not prevent the conversion or
         exchange of any securities pursuant to their terms as in effect prior
         to the commencement of such period into or for other securities.

                  (c) Other Registrations. If the Company has previously filed a
         Registration Statement with respect to Registrable Securities, and if
         such previous registration has not been withdrawn or abandoned, the
         Company will not file or cause to be effective any other registration
         of any of the Shares (or securities convertible into or exchangeable or
         exercisable for the Shares) under the Securities Act (except on Form
         S-4 or S-8 or any successor forms or filed in connection with an
         exchange offer or an offering of securities solely to the Company's
         existing employees or security holders), whether on its own or at the
         request of any holder or holders of the Shares (or securities
         convertible into or exchangeable or exercisable for the Shares), until
         a period of at least 120 days has elapsed from the effective date of
         such previous registration (provided that in the case of a Demand
         Registration such period shall commence on the date the Company is
         first served the notice of demand registration and shall continue until
         at least 180 days have elapsed from the effective date of such Demand
         Registration).

                  6. Indemnification; Contribution.

                                      -9-




<PAGE>


                  (a) Indemnification by the Company. The Company agrees to
         indemnify and hold harmless Holder, its officers, directors and agents
         and each Person, if any, who controls Holder within the meaning of
         Section 15 of the Securities Act or Section 20 of the Exchange Act
         (each an 'Indemnitee') from and against any and all losses, claims,
         damages, liabilities and expenses (including reasonable attorneys' fees
         and costs of investigation) arising out of or based upon any untrue
         statement or alleged untrue statement of a material fact contained in
         any Registration Statement or Prospectus, or arising out of or based
         upon any omission or alleged omission to state therein a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading, except insofar as such losses, claims, damages,
         liabilities or expenses arise out of or are based upon information with
         respect to such Indemnitee furnished in writing to the Company by such
         Indemnitee expressly for use therein. It is agreed that the
         indemnification agreement contained in this Section 6(a) shall not
         apply to amounts paid in settlement of any such loss, claim, damage or
         liability if such settlement is effected without the consent of the
         Company (which consent has not been unreasonably withheld). The Company
         also agrees to indemnify any underwriters on substantially the same
         basis as that of the indemnification of Holder provided in this Section
         6(a).

                  (b) Conduct of Indemnification Proceedings. If any action or
         proceeding (including any governmental investigation) shall be brought
         or asserted against Holder (or its officers, directors or agents) or
         any Person controlling Holder in respect of which indemnity may be
         sought from the Company, the Company shall be permitted to assume the
         defense of such claim, unless in the reasonable judgment of such
         Indemnitee a conflict of interest may exist between such Indemnitee and
         the Company with respect to such claim or differing or additional
         defenses may be available to such Indemnitee. If defense of a claim is
         assumed by the Company, Indemnitees shall not be liable for any
         settlement of such action or proceedings effected without their prior
         written consent. The Company will not consent to entry of any judgment
         or enter into any settlement which does not include as an unconditional
         term thereof the giving by the claimant or plaintiff to such Indemnitee
         of a release from all liability in respect of such claim or litigation.
         If the Company is not entitled to, or elects not to, assume the defense
         of a claim, it will not be obligated to pay the fees and expenses of
         more than one counsel for the Indemnitees as a group with respect to
         such claim in each jurisdiction in which a claim is brought, unless in
         the reasonable judgment of any Indemnitee a conflict of interest may
         exist between such Indemnitee and any other Indemnitee with respect to
         such claim or differing or additional defense may be available to such
         Indemnitee, in which event the Company shall be obligated to pay the
         fees and expenses of such additional counsel. Holder agrees to give
         prompt written notice to the Company after its receipt of any written
         notice of the commencement of any action, suit, proceedings or
         investigation or threat thereof made in writing for which Holder may
         claim indemnification or contribution pursuant to this Agreement;
         provided,


                                      -10-




<PAGE>


         however, that failure to give such notice shall not limit the
         Indemnitee's right to indemnification or contribution hereunder unless
         and to the extent that the Company did not otherwise learn of such
         action and such failure results in the forfeiture by it of substantial
         rights and defenses.

                  (c) Indemnification by Holder. Holder agrees to indemnify and
         hold harmless the Company, and its directors, officers and agents and
         each Person, if any, who controls the Company within the meaning of
         either Section 15 of the Securities Act or Section 20 of the Exchange
         Act to the same extent as the foregoing indemnity from the Company to
         Holder but only with respect to information furnished in writing by
         Holder with respect to Holder which contained a material misstatement
         of fact or omission of a material fact expressly for use in any
         Registration Statement or any amendment thereto or any Prospectus, or
         any preliminary Prospectus relating to the Registrable Securities. In
         case any action or proceeding shall be brought against the Company,
         Holder or any of its respective directors, officers or agents, or any
         such controlling Person, in respect of which indemnity may be sought
         against Holder, Holder shall have the rights and duties given to the
         Company, and the Company, or its directors, officers or agents or such
         controlling Person, shall have the rights and duties given to Holder by
         Section 6(b).

                  (d) Contribution. If the indemnification provided for in this
         Section 6 is unavailable to the Company, Holder or the underwriters in
         respect to any losses, claims, damages, liabilities or judgments
         referred to herein, then each such indemnifying party, in lieu of
         indemnifying such indemnified party, shall contribute to the amount
         paid or payable by such indemnified party as a result of such losses,
         claims, damages, liabilities and judgments in such proportion as is
         appropriate to reflect the relative fault of the indemnifying parties
         and indemnified parties in connection with such statements or omissions
         which resulted in the losses, claims, damages, liabilities or
         judgments, as well as any other relevant equitable considerations. The
         relative fault of such indemnifying party and indemnified parties shall
         be determined by reference to, among other things, whether the untrue
         or alleged untrue statement of a material fact or the omission or
         alleged omission to state a material fact relates to information
         supplied by such party, and the parties' relative intent, knowledge,
         access to information and opportunity to correct or prevent such
         statement or omission.

                  The Company and the Holder agree that it would not be just and
         equitable if contribution pursuant to this Section 6(d) were determined
         by pro rata allocation or by any other method of allocation which does
         not take account of the equitable considerations referred to in the
         immediately preceding paragraph. The amount paid or payable by an
         indemnified party as a result of the losses, claims, damages,
         liabilities or judgments referred to in the immediately preceding
         paragraph shall be deemed to include, subject to the limitation set
         forth above, any legal or other expenses reasonably incurred by such
         indemnified party in


                                      -11-




<PAGE>

         connection with investigating or defending any such action or claim. No
         Person guilty of fraudulent misrepresentations (within the meaning of
         Section 11(f) of the Securities Act) shall be entitled to contribution
         from any Person who was not guilty of such fraudulent
         misrepresentations. For the purposes of this Section 6(d), each
         director of the Company, each officer who signed the Registration
         Statement and each Person, if any, who controls the Company within the
         meaning of Section 15 of the Securities Act shall have the same rights
         to contribution as the Company.

                  7. Participation in Underwritten Registrations. Holder may not
participate in any underwritten Registration hereunder (which shall be conducted
in accordance with the provisions of Section 2(b) or 3) unless Holder (i) agrees
to sell Holder's Registrable Securities on the basis provided in any
underwriting arrangements (approved by Holder as provided herein) and (ii)
completes and executes all questionnaires, powers of attorney, underwriting
agreements and other documents reasonably required under the terms of such
underwriting arrangements and these registration rights; provided, however, that
Holder shall not be required to make representations or give indemnifications
except with respect to information provided in writing by Holder concerning
Holder and its plan of distribution.

                  8. Rule 144. The Company covenants that it will file any
reports required to be filed by it under the Securities Act and the Exchange Act
and the rules and regulations adopted by the Commission thereunder (or, if the
Company is not required to file such reports, it will, upon the request of
Holder, make publicly available other information so long as necessary to permit
sales under Rule 144 under the Securities Act), that it will take such further
action as Holder may reasonably request, all to the extent required from time to
time to enable Holder to sell Registrable Securities without registration under
the Securities Act within the limitations of the exemptions provided by (i) Rule
144 under the Securities Act, as such rule may be amended from time to time, or
(ii) any similar rule or regulation hereafter adopted by the Commission. Upon
the request of Holder, the Company will deliver to Holder a written statement as
to whether it has complied with the requirements of this Section 8.

                  9. Registration Expenses. The Registration Expenses related to
the first Demand Registration or any Piggyback Registration shall be borne
solely by the Company.

                  10. Stand-Off and Special Audit.

                  (a) Stand-Off. If at the time of any request for a Demand
         Registration pursuant to Section 3, the Company (i) is engaged or has
         fixed plans to engage, within 30 days of the time of the request, in a
         registered public offering as to which Holder may, pursuant to Section
         2, include all Registrable Securities proposed to be sold by them, and
         which in fact becomes effective within 90 days after the request, or
         (ii) is engaged in any other activity which, in the good faith


                                      -12-




<PAGE>



         determination of the Company's board of directors, would be adversely
         affected by the Demand Registration to the material detriment of the
         Company, then the Company may at its option direct that such request be
         delayed for a period not to exceed six months from the effective date
         of such offering or the date of commencement of such other material
         activity, as the case may be, provided that Holder has had no other
         request delayed during the six months prior to such request.

                  (b) Provisions for Special Audit. In the event that a special
         audit of the Company's financial statements would be required to effect
         a Registration pursuant to Section 3, the Company shall promptly notify
         Holder that a special audit is required. In such event, Holder shall
         have the right to either (i) withdraw such request for Registration, in
         which case the request shall not count as a Demand Registration to
         which Holder is entitled under this Agreement or (ii) pay the expenses
         of conducting the special audit.

                  11. Public Trading Market. Until the earlier of (a) three
years after the date hereof or (b) the date on which there are no Registrable
Securities, the Company shall use its best efforts to maintain a public trading
market for its Shares.

                  12. Miscellaneous.

                  (a) Amendments and Waivers. This Agreement may not be amended
         without the written consent of the parties hereto.

                  (b) Successors and Assigns. This Agreement shall be binding
         upon and shall inure to the benefit of the parties hereto and their
         respective successors and permitted assigns. No other person shall
         acquire or have any rights under or by virtue of this Agreement.

                  (c) Notices. All notices and other communications provided for
         hereunder shall be given and shall be effective as provided in the
         warrant.

                  (d) Descriptive Headings. The headings in this Agreement are
         for convenience of reference only and shall not limit or otherwise
         affect the meaning of terms contained herein.

                  (e) Severability. In the event that any one or more of the
         provisions, paragraphs, words, clauses, phrases or sentences contained
         herein, or the application thereof in any circumstances, is held
         invalid, illegal or unenforceable in any respect for any reason, the
         validity, legality and enforceability of such provision, paragraph,
         word, clause, phrase or sentence in every other respect and of the
         remaining provisions, paragraphs, words, clauses, phrases or sentences
         hereof shall not be in any way impaired, it being intended that all
         rights, powers


                                      -13-




<PAGE>

         and privileges of the parties hereto shall be enforceable to the
         fullest extent permitted by law.



                  (f) Counterparts. This Agreement may be executed in two or
         more counterparts, each of which shall be deemed an original, but all
         of which shall constitute one and the same instrument, and it shall not
         be necessary in making proof of this Agreement to produce or account
         for more than one such counterpart.

                  (g) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND
         CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW
         YORK.

                  (h) Remedies. The Company acknowledges that monetary damages
         will not be adequate compensation for any loss incurred by reason of a
         breach by it of the provisions hereof and agrees, to the fullest extent
         permitted by law, to waive the defense of adequacy of legal remedies in
         any action for specific performance hereof.

                  (i) Merger, etc. If, directly or indirectly, (i) the Company
         shall merge with and into, or consolidate with, any other Person, (ii)
         any Person shall merge with and into, or consolidate with, the Company
         and the Company shall be the surviving corporation of such merger or
         consolidation and, in connection with such merger or consolidation, all
         or part of the Registrable Securities shall be changed into or
         exchanged for stock or other securities of any other Person, then, in
         each such case, proper provision shall be made so that such Person
         shall be bound by the provisions of this Agreement and the term
         'Company' shall thereafter be deemed to refer to such Person.

                  (j) Other Agreements. The Company shall not enter into any
         agreement inconsistent with any of the provisions hereof.

No. 1                                                                 $1,000,000

                             NAI TECHNOLOGIES, INC.

                        12% Subordinated Promissory Note
                              due January 15, 1996

THIS NOTE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED,
AND MAY NOT BE SOLD, PLEDGED, HYPOTHECATED, DONATED OR OTHERWISE TRANSFERRED
WITHOUT COMPLIANCE WITH THE REGISTRATION OR QUALIFICATION PROVISIONS OF
APPLICABLE FEDERAL SECURITIES LAWS OR APPLICABLE EXEMPTIONS THEREFROM.

                  FOR VALUE RECEIVED, NAI Technologies, Inc., a New York
corporation (the 'Company'), promises to pay to CHARLES S. HOLMES, the
registered holder or registered assigns hereof (the 'Holder'), the principal
amount of ONE MILLION DOLLARS ($1,000,000) payable on the fifteenth day of
January, 1996 (the 'Maturity Date'), together with interest on the outstanding
principal amount of this Note at the rate of twelve (12%) percent per annum
calculated on the basis of a 360 day year, such interest to be payable on the
Maturity Date. If the Company shall default in the payment of the principal of
or interest on this Note, whether upon maturity, by acceleration, or otherwise,
the Company shall on demand from time to time pay interest, to the extent
permitted by law, on such defaulted amount up to (but not including) the date of
actual payment (whether before or after judgment) at a rate per annum (computed
on the basis of the actual number of days elapsed over a year of 360 days) equal
to two (2%) percent. The Holder of this Note shall also, in addition to any
other amount payable hereon, be entitled, as hereinafter provided, to receive a
placement fee in an amount equal to three percent (3%) of the outstanding
principal amount of this Note (the 'Placement Fee'). Capitalized terms used and
not otherwise defined herein shall have the respective meanings attributed
thereto in Section 11.

                  1. Payments and Prepayments.

                  1.1 Payments of principal, Placement Fee and interest on this
Note shall be made at the principal office of the Company, currently located at
1000 Woodbury Road, Suite 412, Woodbury, New York 11797, or such other place or
places within the United States as may be specified by the Holder of this Note
in a written notice to the Company at least 10 business days before a given
payment date.

                  1.2 Payments of principal, Placement Fee and interest on this
Note shall be made in lawful money of the United States of America by mailing
the Company's good check in the proper amount to the Holder at least three days
prior to the due date of each payment or otherwise transferring funds so as to
be received by the Holder on the due date of each such payment, provided,
however, that the Company shall make payment by wire

<PAGE>



transfer to an account such Holder may specify in writing to the Company at
least three days prior to the due date of each payment.


                  1.3 If any payment on this Note becomes due and payable on a
Saturday, Sunday or other day on which commercial banks in New York, New York
are authorized or required by law to close, the maturity thereof shall be
extended to the next succeeding business day, and, with respect to payments of
principal, interest thereon shall be payable during such extension at the then
applicable rate.

                  1.4 This Note is subject to exchange in accordance with the
terms of that certain Securities Purchase Agreement, dated as of the date
hereof, between the Company and Charles S. Holmes and upon any such exchange,
the Company shall, subject to the provisions of Sections 5 and 6 below, pay the
Holder all interest on this Note accrued and unpaid through such exchange date.

                  1.5 Subject to the provisions of Sections 5 and 6 below, the
Company shall, within thirty (30) business days of the occurrence of a Change in
Control, offer, by written notice to the Holder, to prepay this Note, in whole
and not in part, without premium or penalty. Holder may accept the offer to
prepay made pursuant to this Section 1.5 by causing notice of such acceptance to
be delivered to the Company at least ten (10) days prior to the proposed
prepayment date (or such longer period as may be required by law). A failure by
Holder to respond to an offer to prepay pursuant to this Section 1.5 within the
requisite time period shall be deemed to constitute a rejection of such offer.

                  1.6 The Company shall not be entitled to prepay this Note in
whole or in part prior to the Maturity Date.

                  2. Placement Fee. Simultaneously with the initial issuance of
this Note, the Company shall pay to the Holder the Placement Fee, as a one time
fee for services rendered, which Placement Fee the Holder may deduct from the
funds remitted to the Company by the Holder in exchange for the issuance of this
Note.

                  3. Obligation Absolute. The obligations under this Note are
absolute and unconditional obligations of the Company and no modification,
release, consent, waiver, removal, rearrangement or amendment shall impair the
obligations of the Company hereunder.

                  4. Security. The payment of this Note is not secured by any
collateral.

                  5. Subordination. (a) The Company for itself, its successors
and assigns, covenants and agrees, and each Holder of this Note by its
acceptance of this Note likewise covenants and agrees, that to the extent
provided below the payment of the principal of and interest on this Note is
hereby expressly subordinated and junior in right of payment, to the extent and
in the manner hereinafter set forth, to all Senior Indebtedness. For purposes
hereof, Senior Indebtedness is defined as:


                                      -2-



<PAGE>



                  (i) the principal of, premium, if any, any interest (including
         without limitation any interest on interest and post-petition interest)
         on, and all obligations of the Company for any costs and expenses with
         respect to, all liabilities of the Company, direct or contingent,
         joint, several or independent, now or hereafter existing, due or to
         become due, whether created directly or acquired by assignment or
         otherwise, under or in respect of that certain Amended and Restated
         Credit Agreement, dated as of April 12, 1995, among, the Company, The
         Bank of New York, Chemical Bank and the other parties referred to
         therein (as heretofore and as hereafter amended, modified and
         supplemented from time to time, the 'Bank Credit Agreement') and any of
         the other Loan Documents (as defined in the Bank Credit Agreement); and

                  (ii) all extensions, renewals and refundings of any of the
         foregoing.

                  (b) Upon the acceleration of any Senior Indebtedness or upon
the maturity of the entire principal amount of any Senior Indebtedness by lapse
of time, acceleration or otherwise, all such Senior Indebtedness which has been
so accelerated or matured shall first indefeasibly be paid in full in cash
before any payment is made by the Company or any Person acting on behalf of the
Company on account of any obligations evidenced by this Note.

                  (c) The Company shall not pay any obligations evidenced by
this Note if there exists a Default or Event of Default (as such terms are
defined in the instruments evidencing Senior Indebtedness including, without
limitation, the Bank Credit Agreement) with respect to any Senior Indebtedness
(hereinafter referred to as a 'Blockage Event').

                  The Company shall resume payment of this Note and a Blockage
Event shall be deemed to have terminated:

                  (i) when such Default or Event of Default on Senior
         Indebtedness, as applicable, is cured or waived; or

                  (ii) when the Holder hereof shall have cured any such Default
         or Event of Default on Senior Indebtedness to the extent such Default
         or Event of Default can be cured by payment of money, which amount
         shall be added to the principal amount owing to the Holder pursuant to
         this Note; or

                  (iii) 180 days after the occurrence of such Default or Event
         of Default, provided, that at the end of such 180 days, if any of the
         following events occurs, the Blockage Event shall continue: (A) a
         Default in payment of any amount with respect to the Senior
         Indebtedness; (B) an acceleration of the Senior Indebtedness; or (C)
         the occurrence of an event of the type described in Section 6 hereof,
         provided further, that a Blockage Event may be deemed to occur, with
         respect to any single specified Default or Event of Default, only once
         for each 360 day period.

<PAGE>


                  (d) At any time there exists a Blockage Event, (i) the Company
shall not, directly or indirectly, make any payment of any part of this Note,
(ii) the Holder hereof shall not demand or accept from the Company or any other
Person any such payment or cancel, set off or otherwise discharge any part of
the indebtedness represented by this Note, and (iii) neither the Company nor the
Holder hereof shall otherwise take or permit any action prejudicial to or
inconsistent with the priority position of any holder of Senior Indebtedness
over the Holder of this Note.

                  (e) Any holder of Senior Indebtedness is hereby authorized to
demand specific performance of this Note, whether or not the Company shall have
complied with the provisions hereof applicable to it, at any time when the
Holder hereof shall have failed to comply with any provision hereof applicable
to him. The Holder hereby irrevocably waives any defense based on the adequacy
of a remedy at law which might be asserted as a bar to the remedy of specific
performance hereof in any action brought therefor by any holder of Senior
Indebtedness. The Holder further (i) waives presentment, demand, notice and
protest in connection with all negotiable instruments evidencing Senior
Indebtedness, notice of any loan made, extension granted or other action taken
in reliance hereon and all demands and notices of every kind in connection with
this Note or Senior Indebtedness; and (ii) assents to any renewal, extension or
postponement of the time of payment of Senior Indebtedness or any other
indulgence with respect thereto, to any substitution, exchange or release of
collateral therefor and to the addition or release of any Person primarily or
secondarily liable thereon.

                  (f) The Company and the Holder shall execute and deliver to
any holder of Senior Indebtedness such further instruments and shall take such
further action as such holder of Senior Indebtedness may at any time or times
reasonably request in order to evidence the subordination of the obligations
hereunder and to otherwise carry out the provisions and intent of this Note.

                  (g) No right of any holder of Senior Indebtedness to enforce
the subordination of the obligations shall be impaired by any act or failure to
act by the Company or the Holder or by their failure to comply with this Note or
any other agreement or document evidencing, related to or securing the
obligations hereunder. Without in any way limiting the generality of the
preceding sentence, the holders of Senior Indebtedness may, at any time and from
time to time, without the consent of or notice to the Holder, without incurring
responsibility to the Holder and without impairing or releasing the
subordination provided in this Note or the obligations of the holder hereof to
the holders of Senior Indebtedness, do any one or more of the following: (i)
change the manner, place or terms of payment of, or renew or alter, any Senior
Indebtedness, or otherwise amend or supplement in any manner, any Senior
Indebtedness or any instrument evidencing the same or any agreement under which
Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise
deal with any property pledged, mortgaged or otherwise securing any Senior
Indebtedness; (iii) release any Person or entity liable in any manner for the
collection of any Senior Indebtedness; and (iv) exercise or refrain from
exercising any rights against the Company or any other Person or entity.


                                      -4-



<PAGE>


                  (h) In the event that the Company shall make any payment or
prepayment to the Holder on account of the obligations under this Note which is
prohibited by this Section 5, such payment shall be held by the Holder, in trust
for the benefit of, and shall be paid forthwith over and delivered to, the
holders of Senior Indebtedness (pro rata as to each of such holders on the basis
of the respective amounts and priorities of Senior Indebtedness held by them) to
the extent necessary to pay all Senior Indebtedness due to such holders in full
in accordance with its terms (whether or not such Senior Indebtedness is due and
owing), after giving effect to any concurrent payment or distribution to or for
the holders of such Senior Indebtedness.

                  (i) After all Senior Indebtedness indefeasibly is paid in full
and until the obligations under this Note are paid in full, the Holder shall be
subrogated to the rights of holders of Senior Indebtedness to the extent that
distributions otherwise payable to the Holder have been applied to the payment
of Senior Indebtedness. For purposes of such subrogation, no payments or
distributions to holders of such Senior Indebtedness of any cash, property or
securities to which the Holder would be entitled except for the provisions of
this Section 5 and no payment over pursuant to the provisions of this Section 5
to holders of such Senior Indebtedness by the Holder, shall, as between the
Company, its creditors, other than holders of such Senior Indebtedness, and the
Holder, be deemed to be a payment by the Company to or on account of such Senior
Indebtedness, it being understood that the provisions of this Section 5 are
solely for the purpose of defining the relative rights of the holders of such
Senior Indebtedness, on the one hand, and the Holder hereof, on the other hand.

                  6. Primacy of Senior Indebtedness Claims as Against the
Holder. In any insolvency, receivership, bankruptcy, dissolution, liquidation or
reorganization proceeding, or in any other proceeding, whether voluntary or
involuntary, by or against the Company under any bankruptcy or insolvency law or
laws relating to relief of debtors, to compositions, extensions, or
readjustments of indebtedness:

                  (a) the claims of any holders of Senior Indebtedness against
         the Company shall be paid indefeasibly in full in cash before any
         payment is made to the Holder of this Note;

                  (b) until all Senior Indebtedness is indefeasibly paid in full
         any distribution to which the Holder would be entitled but for this
         Section 6 shall be made to holders of Senior Indebtedness; and

                  (c) the holders of Senior Indebtedness shall have the right to
enforce, collect and receive every such payment or distribution and give
acquittance therefor. In furtherance of the foregoing, in the event that the
Company shall file or have filed against it a petition under any chapter of
Title 11 of the United States Code or any comparable statute, with the result
that the Company is excused from the obligation to pay all or any part of the
amount otherwise payable in respect of the Senior Indebtedness during the period
subsequent to the commencement of such proceedings, the Holder agrees that all
or such part of such amount shall be payable out of, and to that extent diminish
and be at the expense of, the


                                      -5-



<PAGE>



Holder's reorganization dividends or other distributions in respect of any claim

                  10.1 Holder hereby acknowledges that this Note is not being
registered (i) under the Act on the ground that the issuance of the Note is
exempt from registration under Section 4(2) of the Act as not involving any
public offering or (ii) under any applicable state securities law because the
issuance of this Note does not involve any public offering; and that the
Company's reliance on the Section 4(2) exemption of the Act and under applicable
state securities laws is predicated in part on the representations hereby made
to the Company by the Holder that it is acquiring this Note for investment for
its own account, with no present intention of dividing its participation with
others or reselling or otherwise distributing the same, provided, nevertheless,
that the disposition of its property shall at all times be within its control.

                  10.2 Holder hereby agrees that it will not sell or transfer

either (a) an opinion, reasonably satisfactory to counsel for the Company, of
counsel (skilled in securities matters, selected by the Holder and reasonably
satisfactory to the Company) to the effect that the proposed sale or transfer
may be made without registration under the Act or (b) an interpretive letter
from the Securities and Exchange Commission to the effect that no enforcement
action will be recommended if the proposed sale or transfer is made without
registration under the Act.

Executive shall be eligible and participate in all employee benefit programs or
plans now or hereafter provided for by the Company for its executive officers in
accordance with the provisions, terms and any limitations thereof, including,
without limitation, life insurance, health, disability and other fringe benefit
plans. Any benefits that are vested as of the Effective Date, including any
pension benefits described in Section 3.5, Executive's rights to retiree medical
benefits, and Executive's rights to the continution of the split dollar
insurance plan with respect to Executive, shall not be affected by this

granted options to purchase two hundred and fifty thousand (250,000) shares of
Common Stock of the Company at a per share exercise price of two dollars and

effect. The Stock Options shall vest during the periods of the Executive's
continued employment with the Company as follows:

                  On or after twelve (12)

                  On or after twenty (24)
                  months from the Effective Date:          125,000 shares



                                      -2-
<PAGE>



The right of exercise shall be cumulative. All such options, to the extent
exercisable, must be exercised within six (6) years of the date hereof, and
shall be in the form of the Company's standard stock option agreements.
Notwithstanding anything contained herein to the contrary, if: (a) the
Executive's employment is terminated by the Company without Cause, or he resigns
for Good Reason, all Stock Options will be 100% vested and will extend for one
year after such termination or resignation; and (b) the Executive's employment
is terminated by the Company for Cause, or he resigns without Good Reason, all
Stock Options will terminate thirty (30) days after such termination or
resignation.

         5.       Termination of Employment.

                  5.1. Cause. 'Cause' shall mean fraud, negligence, conflict of
interest, willful malfeasance or willful misfeasance in office.

                  5.2. Good Reason. 'Good Reason' shall mean:

                  (a) without the express prior written consent of the
         Executive, a material diminution or limitation of the Executive's
         position, duties or responsibilities with the Company from those in
         existence on the Effective Date (or, if greater, the highest
         permanent-assignment level in effect thereafter) or the assignment to
         the Executive of duties inconsistent with the position, duties,
         responsibilities or status of the Executive as of the Effective Date
         (or, if greater, the highest permanent-assignment level in effect
         thereafter); or

                  (b) any failure by the Company to pay, or any reduction by the
         Company of, the base Salary of the Executive as in effect on the
         Effective Date or as the same may be increased from time to time
         thereafter; or

                  (c) the failure of the Company to provide the Executive with
         the opportunity to participate, on terms no less favorable than those
         existing on the Effective Date, in any incentive benefit, bonus or
         compensation, insurance, pension or other employee benefit plan of the
         Company in effect on the Effective Date (or plans and benefits which
         are, in the aggregate, no less favorable to the Executive than those
         the Executive enjoyed on the Effective Date) unless such failure
         results from the Company's termination or amendment of any such plan in
         response to a change in applicable statute



                                      -3-
<PAGE>

         or regulation, including any termination or amendment resulting from a
         materially adverse alteration of the tax treatment of any such plan to
         the Company or to plan participants; provided, however, that Good
         Reason shall not include any reduction in such benefit by the Company
         on a Company-wide basis.

                  5.3. Notice of Good Reason.

                  Unless the Executive provides written notification of his
intention to resign within twenty (20) business days after the Executive knows
or has reason to know of the occurrence of any such event constituting Good
Reason, the Executive shall be deemed to have consented thereto and such event
shall no longer constitute Good Reason for purposes of this Agreement. If the
Executive provides such written notice to the Company, the Company shall have
twenty (20) business days from the date of receipt of such notice to effect a
cure of the event described therein and, upon cure thereof by the Company to the
reasonable satisfaction of the Executive, such event shall no longer constitute
Good Reason for purposes of this Agreement.

                  5.4. Termination For Cause; Resignation
                       Without Good Reason.

                  (a) Rights on Termination. If, prior to the expiration of the
         Term, the Executive's employment is terminated by the Company for Cause
         or the Executive resigns from this employment without Good Reason, the
         Executive shall be entitled to payment of his Salary accrued through
         the date of such termination or resignation, plus any accrued but
         unpaid vacation benefits. Except as may be provided by law or expressly
         provided under the term of any plan or arrangement applicable to the
         Executive, the Executive shall have no right under this Agreement or
         otherwise to receive any other compensation or benefits, or to
         participate in any other plan, arrangement or benefit, with respect to
         future periods after such termination or resignation of Effective.

                  (b) Notice of Termination for Cause. Termination of the
         Executive's employment for Cause shall be communicated by delivery to
         the Executive of a copy of a resolution duly adopted by the Board
         finding that in the good faith opinion of the Board an event
         constituting Cause for termination in accordance with Section 5.1 has
         occurred and specifying the particulars thereof (a 'Notice of
         Termination'). In the event of termination for Cause as a consequence
         of the events described in Section 5.1 or any other event described




                                      -4-
<PAGE>



         in Section 5.1 that the Board determines in good faith is not
         susceptible of cure, the effective date of termination shall be the
         date of the Notice of Termination or such later date as may be
         specified in such notice. In the event the Executive's employment is
         terminated for Cause (unless the Board has determined in good faith
         that the relevant giving rise to Cause is not susceptible of cure), the
         Executive shall have twenty (20) business days from the date of receipt
         of such Notice of Termination to effect a cure of the event described
         therein and, upon cure thereof by the Executive to the reasonable
         satisfaction of the Board, such event shall no longer constitute Cause
         for purposes of this Agreement. The effective date of termination for
         Cause that has been subject to a cure period as described in the
         immediately preceding sentence which did not result in a cure to the
         reasonable satisfaction of the Board shall be the date immediately
         succeeding the last date of the twenty (20) business day cure period.

                  (c) Notice of Resignation Without Good Reason.

                  The date of resignation by the Executive without Good Reason
         shall be the date specified in a written notice of resignation from the
         Executive to the Company. The Executive shall provide at least sixty
         (60) days' advance written notice of resignation.

                  5.5. Notice of Termination Without Cause.

                  The date of termination of employment without Cause shall be
the date specified in a written notice of termination to the Executive, provided
that the Company shall provide at least twenty (20) business days' written
notice of such termination.

                  5.6. Notice of Resignation for Good Reason.

                  The date of resignation for Good Reason shall be the date
specified in a written notice of resignation from the Executive to the Company,
provided, however, that no such written notice shall be effective unless the
twenty (20) business day cure period specified in Section 5.3 has expired
without the Company having corrected, to the reasonable satisfaction of the
Executive, the event or events.

                  5.7. Termination Without Cause;
                       Resignation For Good Reason.

                  (a)      Severance Amount.  If, prior to the expiration
         of the Term, the Executive's employment is




                                      -5-
<PAGE>



         terminated by the Company without Cause, or the Executive resigns from
         his employment for Good Reason, the Company shall pay to the Executive
         his Salary accrued up to and including the effective date of such
         termination or resignation, plus a pro rata share of unused vacation
         for the full year plus a pro rata bonus under the Company Bonus Plan,
         if the Board in its sole discretion so determines, all in a lump sum.
         In addition, the Company shall pay to the Executive a severance payment
         equal to the greater of (A) his salary, at the rate in effect at time
         of such termination or resignation, for the remainder of the Term and
         (B) one year's salary, at the rate in effect at the time of such
         termination or resignation, in a lump sum (the 'Severance Amount').

                  (b) Other Benefits. In the event of the Executive's
         termination without Cause or his resignation for Good Reason, the
         Executive shall continue to participate on the same terms and
         conditions as in effect immediately prior to such termination or
         resignation in each pension, life insurance, health, disability and
         other fringe benefit plan or program provided to the Executive pursuant
         to Sections 3.3, 3.5 and 3.6 at the time of such termination or
         resignation until the earlier of (A) six (6) months following the date
         of such termination or resignation or, if the Executive is required to
         elect such benefits immediately following such termination or
         resignation, twelve (12) months following the date of such termination
         or resignation and (B) such time as the Executive is eligible to be
         covered by a comparable program of a subsequent employer. The Executive
         agrees to notify the Company promptly if he becomes eligible to
         participate in any pension or other benefit plans, programs or
         arrangements of another employer. Notwithstanding anything contained
         herein to the contrary, the Company shall have no obligation to
         continue to maintain any plan or program solely as a result of the
         provisions of this Agreement nor provide any level of benefits if
         applicable law either prevents the Executive from participating in any
         such plan or program or would cause the Company to suffer any loss of
         tax benefits as a consequence of the Executive's continued
         participation during the Term.

                  (c) Automobile: If the Company has provided the Executive with
         the use of an automobile on a continuous basis prior to the termination
         without Cause or resignation for Good Reason, the Executive shall be
         given the option to purchase such automobile on the terms outlined in
         the Company policy with respect thereto at the value



                                      -6-
<PAGE>



         in effect two years after the date of the termination without Cause or
         resignation for Good Reason.

                  5.8. Termination Due to Death or Disability.

                  (a) In the event of the Executive's disability, as hereinafter
         defined, or death, the Company shall be entitled to terminate his
         employment. If the Executive's employment shall terminate due to
         disability or death, any Salary earned by the Executive up to the date
         of such termination and any pro rata bonus to that date shall be paid
         to the Executive or his estate, as appropriate.

                  (b) As used herein, the term 'disability' shall mean physical
         or mental disability as a result of which the Executive is unable to
         perform his duties hereunder on substantially a full-time basis for any
         period of four (4) consecutive months. Any dispute as to whether or not
         the Executive is so disabled shall be resolved by a physician,
         reasonably acceptable to the Executive and the Board, whose
         determination shall be final and binding upon both the Executive and
         the Company.

         6. Nondisclosure of Confidential Information. The Executive shall be
bound by the confidentiality policy of the Company. The Executive shall not,
except as may be necessary in the discharge of duties with the Company or as may
be required by applicable law or regulations, disclose any confidential
information, knowledge or data obtained by the Executive prior to the date of
this Agreement or during the Executive's employment concerning the Company or
the business of the Company so long as such information is not publicly
available.

         7. Arbitration. Any controversy or claim arising out of or relating to
this Agreement or the breach of this Agreement that cannot be resolved by the
Executive and the Company shall, at the instance of either the Executive or the
Company, be submitted to arbitration in accordance with New York law and the
procedures of the American Arbitration Association, with all hearings to be
conducted in Colorado. The determination of the arbitrator shall be conclusive
and binding on the Company and the Executive and judgment may be entered on the
arbitrator's award in any court having jurisdiction.

         8. Legal Expenses. The Company shall pay all reasonable costs and
expenses, including attorneys' fees and disbursements, of the Company and, at
least monthly, the Executive in connection with any legal proceedings (in the
case of the Executive any legal proceedings brought or


                                      -7-
<PAGE>


maintained in good faith) (including, but not limited to, arbitration), whether
or not instituted by the Company or the Executive, relating to the
interpretation or enforcement of any provision of this Agreement.

         9. Assignability. The respective rights and obligations of the
Executive and the Company under this Agreement shall inure to the benefit of and
be binding upon the heirs and legal representatives of the Executive and the
successors and assigns of the Company. The Executive's rights and obligations
under this Agreement may not be assigned or alienated and any attempt to do so
by the Executive shall be void. Any successor (whether direct or indirect, by
purchase, merger, consolidation or otherwise) to all or substantially all of the
business or assets of the Company, shall assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would be
required to perform it if no such succession had taken place. The provisions of
this Section 9 shall continue to apply to each subsequent employer of the
Executive hereunder in the event of any subsequent merger, consolidation or
transfer of assets of such subsequent employer.

         10. Severability. If any provision of this Agreement is deemed to be
invalid or unenforceable or is prohibited by the laws of the state or place
where it is to be performed, this Agreement shall be considered to be divisible
as to such provision and such provision shall be inoperative in such state or
place and shall not be part of the consideration moving from either of the
parties to the other. The remaining provisions of the Agreement, however, shall
be valid and binding and of like effect as though such provision were not
included.

         11. Miscellaneous. This Agreement is to be construed and enforced in
accordance with the internal substantive laws of the State of New York,
irrespective of the principles of conflicts of law. The waiver of any breach of
this Agreement by any party shall not be construed as a waiver of any subsequent
breach by any party. This Agreement may not be changed orally, but only by an
agreement in writing signed by the parties to this Agreement.

                              EMPLOYMENT AGREEMENT


                  This Employment Agreement, entered into as of the 16th day of
October, 1995 by and between NAI Technologies, Inc., a New York corporation (the
'Company'), and Richard A. Schneider (the 'Executive').

         1.       Termination of Prior Agreement. Upon the execution of this
Agreement, the prior agreement entered into by and between the Executive and the
Company, dated as of February 5, 1995, shall be terminated in all respects and
be superseded by this Agreement.

         2.       Employment and Duties.

                  2.1. Duties. Upon the terms and conditions herein set forth,
the Company employs the Executive, and the Executive hereby agrees to serve as

effective October 16, 1995 (the 'Effective Date'). The Executive shall devote
his best efforts to such duties with the Company as the Board of Directors may
direct.

                  2.2. Term. The term of the Executive's employment under this
Agreement (the 'Term') shall commence on the Effective Date and shall continue
until the second anniversary of such date. Thereafter, the Term may be extended

however, shall limit the right of the Company or the Executive to terminate the
Executive's employment hereunder on the terms and conditions set forth in
Section 5.

         3.       Compensation and Other Benefits. Subject to the provisions of
this Agreement, the Company shall pay and provide the following compensation and

                  (b) Pursuant to the Agreement the Company will loan to
         Executive the equivalent of the difference between his net Salary and
         the net salary he was receiving immediately prior to the execution of
         this Agreement ($550.00 per week). This loan shall be repayable out of
         any Bonus paid to Executive on account of work performed during the
         prior year; provided, however, that upon a resignation for Good Reason
         or termination without Cause the full amount outstanding under such
         loans shall be discharged in full.

plans now or hereafter provided for by the Company for its executive officers in
accordance with the provisions, terms and any limitations thereof, including,

         months from the Effective Date:                     62,500 shares

year after such termination or resignation; and (b) the Executive's employment
is terminated by the Company for Cause or he resigns his employment with the
Company without Good Reason, all Stock Options will terminate thirty (30) days
after such termination or resignation.

         Executive, a material diminution or limitation of the Executive's
         position, duties or responsibilities with the Company from those in
         existence on the Effective Date (or, if greater, the highest
         permanent-assignment level in effect thereafter) or the assignment to
         the Executive of duties inconsistent with the position, duties,
         responsibilities or status of the Executive as of the Effective Date
         (or, if greater, the highest permanent-assignment level in effect
         thereafter); or

                  (b) any failure by the Company to pay, or any reduction by the
         Company of, the base Salary of the Executive as in effect on the
         Effective

         Date or as the same may be increased from time to time thereafter; or

                  (c) the failure of the Company to provide the Executive with
         the opportunity to participate, on terms no less favorable than those
         existing on the Effective Date, in any incentive benefit, bonus or
         compensation, insurance, pension or other employee benefit plan of the
         Company in effect on the Effective Date (or plans and benefits which
         are, in the aggregate, no less favorable to the Executive than those
         the Executive enjoyed on the Effective Date) unless such failure
         results from the Company's termination or amendment of any such plan in
         response to a change in applicable statute or regulation, including any
         termination or amendment resulting from a materially adverse alteration
         of the tax treatment of any such plan to the Company or to plan
         participants; provided, however, that Good Reason shall not include any
         reduction in such benefit by the Company on a Company-wide basis.

                  5.3. Notice of Good Reason.

                  Unless the Executive provides written notification of his
intention to resign within twenty (20) business days after the Executive knows
or has reason to know of the occurrence of any such event constituting Good
Reason, the Executive shall be deemed to have consented thereto and such event
shall no longer constitute Good Reason for purposes of this Agreement. If the
Executive provides such written notice to the Company, the Company shall have
twenty (20) business days from the date of receipt of such notice to effect a
cure of the event described therein and, upon cure thereof by the Company to the
reasonable satisfaction of the Executive, such event shall no longer constitute
Good Reason for purposes of this Agreement.

                  5.4.     Termination For Cause; Resignation
                           Without Good Reason.

                  (a) Rights on Termination. If, prior to the expiration of the
         Term, the Executive's employment is terminated by the Company for Cause
         or the Executive resigns from this employment without Good Reason, the
         Executive shall be entitled to payment of his Salary accrued through
         the date of such termination or resignation, plus any accrued but
         unpaid vacation benefits. Except as may be provided by law or expressly
         provided under the term of any plan or arrangement applicable to the
         Executive, the Executive shall have no right under this Agreement or
         otherwise


                                      -4-
<PAGE>



         to receive any other compensation or benefits, or to participate in any
         other plan, arrangement or benefit, with respect to future periods
         after such termination or resignation of Employment.

                  (b) Notice of Termination for Cause. Termination of the
         Executive's employment for Cause shall be communicated by delivery to
         the Executive of a copy of a resolution duly adopted by the Board
         finding that in the good faith opinion of the Board an event
         constituting Cause for termination in accordance with Section 5.1 has
         occurred and specifying the particulars thereof (a 'Notice of
         Termination'). In the event of termination for Cause as a consequence
         of the events described in Section 5.1 or any other event described in
         Section 5.1 that the Board determines in good faith is not susceptible
         of cure, the effective date of termination shall be the date of the
         Notice of Termination or such later date as may be specified in such
         notice. In the event the Executive's employment is terminated for Cause
         (unless the Board has determined in good faith that the relevant giving
         rise to Cause is not susceptible of cure), the Executive shall have
         twenty (20) business days from the date of receipt of such Notice of
         Termination to effect a cure of the event described therein and, upon
         cure thereof by the Executive to the reasonable satisfaction of the
         Board, such event shall no longer constitute Cause for purposes of this
         Agreement. The effective date of termination for Cause that has been
         subject to a cure period as described in the immediately preceding
         sentence which did not result in a cure to the reasonable satisfaction
         of the Board shall be the date immediately succeeding the last date of
         the twenty (20) business day cure period.

                  (c) Notice of Resignation Without Good Reason.

                  The date of resignation by the Executive without Good Reason
         shall be the date specified in a written notice of resignation from the
         Executive to the Company. The Executive shall provide at least sixty
         (60) days' advance written notice of resignation.

                  5.5. Notice of Termination Without Cause.

                  The date of termination of employment without Cause shall be
the date specified in a written notice of termination to the Executive, provided
that the Company shall provide at least twenty (20) business days' written
notice of such termination.

                  5.6. Notice of Resignation for Good Reason.

                  The date of resignation for Good Reason shall be the date
specified in a written notice of resignation from the Executive to the Company,
provided, however, that no such written notice shall be effective unless the
twenty (20) business day cure period specified in Section 5.3 has expired
without the Company having corrected, to the reasonable satisfaction of the
Executive, the event or events.

                  5.7. Termination Without Cause;
                       Resignation For Good Reason.

                  (a) Severance Amount. If, prior to the expiration of the Term,
         the Executive's employment is terminated by the Company without Cause,
         or the Executive resigns from his employment for Good Reason, the
         Company shall pay to the Executive his Salary accrued up to and
         including the effective date of such termination or resignation, plus a
         pro rata share of unused vacation for the full year plus a pro rata
         bonus under the Company Bonus Plan, if the Board in its sole discretion
         so determines. In addition, the Company shall pay to the Executive a
         severance payment equal to the greater of (A) his salary, at the rate
         in effect at time of such termination or resignation, for the remainder
         of the Term and (B) one year's salary, at the rate in effect at the
         time of such termination or resignation, in a lump sum ('Severance
         Amount').

                  (b) Other Benefits. In the event of the Executive's
         termination without Cause or his resignation for Good Reason, the
         Executive shall continue to participate on the same terms and
         conditions as in effect immediately prior to such termination or
         resignation in each pension, life insurance, health, disability and
         other fringe benefit plan or program provided to the Executive pursuant
         to Sections 3.3, 3.5 and 3.6 at the time of such termination or
         resignation until the earlier of (A) six (6) months following the date
         of such termination or resignation or, if the Executive is required to
         elect such benefits immediately following such termination or
         resignation, twelve (12) months following the date of such termination
         or resignation, and (B) such time as the Executive is eligible to be
         covered by a comparable program of a subsequent employer. The Executive
         agrees to notify the Company promptly if he becomes eligible to
         participate in any pension or other benefit plans, programs or
         arrangements of another employer. Notwithstanding anything contained
         herein to the contrary, the Company shall have no obligation to



                                      -6-
<PAGE>



         continue to maintain any plan or program solely as a result of the
         provisions of this Agreement nor provide any level of benefits if
         applicable law either prevents the Executive from participating in any
         such plan or program or would cause the Company to suffer any loss of
         tax benefits as a consequence of the Executive's continued
         participation during the Term.

                  (c) Automobile: If the Company has provided the Executive with
         the use of an automobile on a continuous basis prior to the termination
         without Cause or resignation for Good Reason, the Executive shall be
         given the option to purchase such automobile on the terms outlined in
         the Company policy with respect thereto at the value in effect two
         years after the date of the termination without Cause or resignation
         for Good Reason.

                  5.8. Termination Due to Death or Disability.

                  (a) In the event of the Executive's disability, as hereinafter
         defined, or death, the Company shall be entitled to terminate his
         employment. If the Executive's employment shall terminate due to
         disability or death, any Salary earned by the Executive up to the date
         of such termination and any pro rata bonus to that date shall be paid
         to the Executive or his estate, as appropriate.

                  (b) As used herein, the term 'disability' shall mean physical
         or mental disability as a result of which the Executive is unable to
         perform his duties hereunder on substantially a full-time basis for any
         period of four (4) consecutive months. Any dispute as to whether or not
         the Executive is so disabled shall be resolved by a physician,
         reasonably acceptable to the Executive and the Board, whose
         determination shall be final and binding upon both the Executive and
         the Company.

                  6. Nondisclosure of Confidential Information. The Executive
shall be bound by the confidentiality policy of the Company. The Executive shall
not, except as may be necessary in the discharge of duties with the Company or
as may be required by applicable law or regulations, disclose any confidential
information, knowledge or data obtained by the Executive prior to the date of
this Agreement or during the Executive's employment concerning the Company or
the business of the Company so long as such information is not publicly
available.

                  7. Arbitration. Any controversy or claim arising out of or
relating to this Agreement or the breach



                                      -7-
<PAGE>



of this Agreement that cannot be resolved by the Executive and the Company
shall, at the instance of either the Executive or the Company, be submitted to
arbitration in accordance with New York law and the procedures of the American
Arbitration Association, with all hearings to be conducted in Colorado. The
determination of the arbitrator shall be conclusive and binding on the Company
and the Executive and judgment may be entered on the arbitrator's award in any
court having jurisdiction.

                  8. Legal Expenses. The Company shall pay all reasonable costs
and expenses, including attorneys' fees and disbursements, of the Company and,
at least monthly, the Executive in connection with any legal proceedings (in the
case of the Executive any legal proceedings brought or maintained in good faith)
(including, but not limited to, arbitration), whether or not instituted by the
Company or the Executive, relating to the interpretation or enforcement of any
provision of this Agreement.

                  9. Assignability. The respective rights and obligations of the
Executive and the Company under this Agreement shall inure to the benefit of and
be binding upon the heirs and legal representatives of the Executive and the
successors and assigns of the Company. The Executive's rights and obligations
under this Agreement may not be assigned or alienated and any attempt to do so
by the Executive shall be void. Any successor (whether direct or indirect, by
purchase, merger, consolidation or otherwise) to all or substantially all of the
business or assets of the Company, shall assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would be
required to perform it if no such succession had taken place. The provisions of
this Section 9 shall continue to apply to each subsequent employer of the
Executive hereunder in the event of any subsequent merger, consolidation or
transfer of assets of such subsequent employer.

                  10. Severability. If any provision of this Agreement is deemed
to be invalid or unenforceable or is prohibited by the laws of the state or
place where it is to be performed, this Agreement shall be considered to be
divisible as to such provision and such provision shall be inoperative in such
state or place and shall not be part of the consideration moving from either of
the parties to the other. The remaining provisions of the Agreement, however,
shall be valid and binding and of like effect as though such provision were not
included.

                  11. Miscellaneous. This Agreement is to be construed and
enforced in accordance with the internal substantive laws of the State of New
York, irrespective of



                                      -8-
<PAGE>


the principles of conflicts of law. The waiver of any breach of this Agreement
by any party shall not be construed as a waiver of any subsequent breach by any
party. This Agreement may not be changed orally, but only by an agreement in
writing signed by the parties to this Agreement.

                  IN WITNESS WHEREOF, the Company and the Executive have
executed this Agreement as of the day and year first above written.

to the  assets  of the  Company  and its  Subsidiaries,  which  report  shall be

Event of Default,  or an event with which the giving of notice or the passage of
time, or both, would constitute an Event of Default, exists.

                  Section 8.  Counterparts.  This Amendment may be executed in 
any number  of  counterparts,  each  of  which shall constitute an original and
all of which when taken together shall constitute one and the same instrument.

                  Section 9.  Conditions to Effectiveness.  This Amendment shall
become  effective  upon  the  execution  of  this Amendment by the Company, the 
Administrative Agent, the Collateral Agent and the

                                       3

Banks (and the receipt by the Collateral Agent of evidence satisfactory to it of
such execution) (the 'Effective Date').

                  Section 10. Ratification. Except to the extent hereby amended,
the Credit Agreement remains in full force and effect and is hereby ratified and
affirmed.  References in the Loan Documents to the Credit  Agreement  shall mean
such document as amended by this Amendment,  as the same may be further amended,
supplemented or otherwise modified from time to time.

                  Section 11. Costs and  Expenses.  All  out-of-pocket  expenses

                     AMENDED AND RESTATED CREDIT AGREEMENT


                  SECOND   AMENDMENT,   dated  as  of  October   13,  1995  (the

Chemical  Bank, a New York  banking  corporation  ('Chemical'),  The Bank of New
York, a New York banking  corporation  ('BNY'),  and each of the other financial
institutions  which  from time to time  becomes  party  thereto  (together  with
Chemical and BNY, the 'Banks'),  BNY, as administrative agent (in such capacity,
the 'Administrative Agent') and Chemical, as collateral agent (in such capacity,
the 'Collateral Agent').

                             W I T N E S S E T H :

                  WHEREAS, the Borrower, the Banks, the Administrative Agent and
the  Collateral  Agent are parties to that certain  Amended and Restated  Credit
Agreement,  dated as of  April  12,  1995  (as  amended  by that  certain  First
Amendment to Amended and Restated Credit Agreement, dated as of August 14, 1995,
the 'Credit Agreement');

                  WHEREAS, unless otherwise defined herein, terms defined in the
Credit Agreement and used herein are used herein as therein defined;

                  WHEREAS,  the  Borrower  and Charles  Holmes  ('Holmes')  have
reached  an  agreement  whereby  Holmes  will  make  a  $1,000,000  subordinated
unsecured loan to the Borrower in exchange for certain consideration;

                  WHEREAS,  the Borrower has  requested a limited  waiver of the
financial  covenant  set forth in Section 6.16 of the Credit  Agreement  for the
periods provided herein; and

                  WHEREAS,  the Borrower has requested and the Banks have agreed
to consent to the  incurrence  of such  subordinated  indebtedness  and to waive
compliance  with  the  financial   covenant  referred  to  above  on  the  terms
hereinafter set forth.

                  Accordingly, the parties hereto hereby agree as follows:

                  Section 1.  Amendment  to  Article I.  Article I of the Credit
Agreement is hereby amended by adding the following defined term to Section 1.01
thereof:

         'Second  Amendment' shall mean the Second Amendment dated as of October
         13, 1995 to the Agreement.

Agreement is hereby amended by adding the following sections at the end thereof:



<PAGE>



         Section 5.16.  Delivery of Certificate.  Within five days after the end
         of each  month,  furnish  each of the  Banks  with a  certificate  of a
         Financial  Officer  certifying that neither the Borrower nor any of the
         Guarantors  have sold any Inventory,  fixtures or equipment for amounts
         less than 90% of the book value of such  assets  during  the  preceding
         month.

         Section  5.17.  Additional  Subordinated  Note.  In the event  that the
         Borrower seeks to obtain  $2,000,000 of the  Subordinated  Indebtedness
         permitted  by  Section  6.03(vi)  hereof,  cause  the  promissory  note
         delivered to the Subordinated Lender thereof to be in substantially the
         form of note annexed as Exhibit A to the Second Amendment.

                  Section 3.  Clarification  of Section  6.02.  For  purposes of
clarifying the provisions of Section 6.02, it is understood and agreed among the
parties  hereto that the sale of  Inventory,  fixtures and equipment for amounts
equal to or in excess of 90% of the book value of such assets would constitute a
sale in the  ordinary  course of  business,  and that a sale of such  assets for
amounts  below 90% of the book value of such assets would not  constitute a sale
in the ordinary course of business.

                  Section 4.  Amendments to Article VI. Article VI of the Credit
Agreement is hereby  amended by (a) amending  Section 6.03 thereof to delete the
word  'and'  prior  to  clause  (v) and to add  the  following  language  at the
conclusion of such Section just prior to the period:

         ; and (vi) Indebtedness of the Borrower to Charles Holmes or any of his
         Affiliates (the  'Subordinated  Lender') in an aggregate  amount not to
         exceed $3,000,000 (the 'Subordinated Indebtedness'), which Indebtedness
         shall be  subordinate in right of payment to the  Indebtedness  owed to
         the Bank under this Agreement.

and (b) to add the following section at the end thereof:

         Section  6.18.  Use  of  Proceeds  of  Subordinated  Indebtedness.  The
         Borrower  will  not,  and will not  permit  its  Subsidiaries  to,  use
         proceeds  of the  Subordinated  Indebtedness  for  purposes of mergers,
         acquisitions,  joint ventures or other business combinations.  Any such
         use of the proceeds of the Subordinated  Indebtedness  shall constitute
         an Event of Default under the Agreement.

                  Section  5.  Limited  Waiver  of  Section  6.16;  Consolidated
Tangible Net Worth.  Compliance with the financial covenant set forth in Section
6.16 of the Credit  Agreement  is hereby  waived  for the period  August 1, 1995
through December 15, 1995;  provided,  that the Consolidated  Tangible Net Worth
shall not be less than $1,000,000.

                                       2

<PAGE>




                  Section 6. Confirmation of Liens. The Borrower hereby confirms
that,  pursuant to the terms of the Credit Agreement and the Security Documents,
the Borrower and the Guarantors have granted Liens on all of their assets to the
Collateral  Agent for the  benefit of the Banks.  The  Borrower  hereby  further
confirms that it will not and will not permit its Subsidiaries to incur, create,
assume or suffer to exist any Lien on any property or assets,  income or profits
of the Borrower or any of its Subsidiaries other than those permitted by Section
6.01 of the Credit Agreement, and any such granting of any such Lien in favor of
any third person,  including the holders of the  Subordinated  Indebtedness  (as
hereinafter  defined)  shall  constitute  an Event of  Default  under the Credit
Agreement.  Nothing  contained  herein  (including  the  provisions of Section 2
hereof) shall  constitute a release or  modification of any Lien in favor of the
Collateral Agent and the Banks in any Collateral which constitutes  security for
any of the Obligations.

                  Section 7. Representations and Warranties. The representations
and  warranties  set forth in  Section 3 of the  Credit  Agreement  are true and
correct in all  material  respects on and as of the date  hereof,  except to the
extent that such  representations and warranties  expressly relate to an earlier
date. As of the Effective  Date, and after giving effect to this  Amendment,  no
Event of Default,  or an event with which the giving of notice or the passage of
time, or both, would constitute an Event of Default, exists.

                  Section 8.  Counterparts.  This Amendment may be executed
in any number of counterparts, each of which shall constitute an
original and all of which when taken together shall constitute one
and the same instrument.

                  Section 9. Conditions to  Effectiveness.  This Amendment shall
become  effective as of the date hereof (the  'Effective  Date') when all of the
following shall have occurred:

                           (a)      The Banks shall have each received
         counterparts of this Amendment, duly executed by the Borrower;

                           (b)      The Borrower shall have received $1,000,000
         in cash in respect of Subordinated Indebtedness; and

                           (c) The Banks shall have received a copy of the fully
         executed  promissory note of the Borrower to the Subordinated Lender in
         the form of Exhibit A hereto.

                  Section 10. Ratification. Except to the extent hereby amended,
the Credit Agreement remains in full force and effect and is hereby ratified and
affirmed.  References in the Loan Documents to the Credit  Agreement  shall mean
such document as amended by this Amendment,  as the same may be further amended,
supplemented or otherwise modified from time to time.

                  WHEREAS, the Borrower, the Banks, the Administrative Agent and
the  Collateral  Agent are parties to that certain  Amended and Restated  Credit
Agreement,  dated as of  April  12,  1995  (as  amended  by that  certain  First
Amendment, dated as of August 14, 1995, and that certain Second Amendment, dated
as of October 13, 1995, the 'Credit Agreement');

                  WHEREAS, unless otherwise defined herein, terms defined in the
Credit Agreement and used herein are used herein as therein defined;

                  WHEREAS,  in  connection  with the  Borrower's  incurrence  of
Subordinated Indebtedness,  the Borrower has executed a promissory note in favor

                  discontinuing   the  operation  or  maintenance  of  any  such
                  properties  is, in the judgment of the Borrower,  desirable in
                  the conduct of its business.



<PAGE>




                  Section 2.  Amendments to Article VI. Article VI of the Credit

                  investment,  the giving of any  guarantee or the  rendering of
                  any service)  with any  Affiliate  of the Borrower  unless (i)
                  such transaction or series of related transactions is on terms
                  no less  favorable  to the  Borrower or such  Subsidiary  than
                  those that could be  obtained  in a  comparable  arm's  length
                  transaction  with a Person that is not an Affiliate,  and (ii)
                  such transaction or series of related transactions is approved
                  by a  majority  of the  Board  of  Directors  of the  Borrower
                  (including a majority of the disinterested  directors),  which
                  approval is set forth in a board  resolution  of the  Borrower
                  certifying  that such  transaction  or series of  transactions
                  complies with the immediately preceding clause (i).

and (b)  amending  Section 6.08 thereof to delete both clauses (a) and (b) after
the words 'except for' and to substitute the words 'Permitted Investments'.

                  Section 3.  Amendments  to  Article  VII.  Article  VII of the
Credit  Agreement is hereby amended by (a) amending  Section  7.01(f)(ii)(y)  to

'or'  from the end of  Section  7.01(o)  to the end of Section 7.01(p);  and (d)
adding the following subsection to the end of Section 7.01(p):

                           (q)      all or any substantial part of the assets
                  or property of the Borrower are condemned, seized
                  or appropriated by any Governmental Authority;

                  Section 4. Representations and Warranties. The representations
and  warranties  set forth in  Section 3 of the  Credit  Agreement  are true and
correct in all  material  respects on and as of the date  hereof,  except to the
extent that such  representations and warranties  expressly relate to an earlier
date. As of the Effective Date (as hereinafter defined), and after giving effect
to this  Amendment,  no Event of  Default,  or an event which with the giving of
notice or the passage of time,  or both,  would  constitute an Event of Default,
exists.

with the Credit  Agreement or the Loan  Documents or any of the  instruments  or
agreements referred to therein.

                  Section  9.  Applicable  Law.  THIS  AMENDMENT  SHALL  IN  ALL
RESPECTS BE CONSTRUED IN  ACCORDANCE  WITH AND GOVERNED BY THE LAWS OF THE STATE

Amendment.

                  Section 11. Integration.  This Amendment represents the entire
agreement  of the parties  hereto with  respect to the  amendment  of the Credit
Agreement,  and the terms of any letters and other  documentation  entered  into
among the Borrower and any Bank or the  Administrative  Agent or the  Collateral
Agent prior to the execution of this Amendment  which relate to the amendment of
the Credit Agreement shall be replaced by the terms of this Amendment.

                  Section 12. Execution in  Counterparts.  This Amendment may be
executed  in any  number of  counterparts,  each of which  shall  constitute  an
original,  but all of which taken  together  shall  constitute  one and the same
