             NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

                                  (UNAUDITED)




1.  In the opinion of Management, the accompanying unaudited consolidated
    condensed financial statements contain all adjustments, consisting of
    normal recurring items, necessary to present fairly the financial position,
    results of operations and cash flows for the periods shown.  It is the
    Company's policy to end its first three quarterly accounting periods on the
    last Friday of each quarter, which includes thirteen weeks of operations.
    The fourth quarter ends on March 31.  The financial data included herein
    was compiled in accordance with the same accounting policies applied to the
    Company's audited annual financial statements, which should be read in
    conjunction with these statements.

    The results of operations for the thirteen weeks ended  June 30, 1995  are
    not necessarily indicative of the results to be expected for the full year.


2.  Costs and estimated earnings in excess of billings on uncompleted contracts
    primarily represent revenue recognized on contracts, including retainage,
    for which billings could not be presented under the terms of the contracts
    at the balance sheet dates.


3.  During the thirteen weeks ended June 30, 1995,  12,196 common shares
    were sold from the Company's treasury shares and none were purchased. The
    total number of treasury shares as of June 30, 1995 is 287,578.


4.  The Company granted 162,200 options to purchase stock through its
    equity incentive stock plan during the quarter ended June 30, 1995.
    Options for 204,278 shares were exercisable and 446,590 stock options were
    outstanding at June 30, 1995.


5.  On June 6, 1995, effective May 31, 1995 for financial statement purposes,
    the shareholders of ARIA Wireless Systems, Inc. (old ARIA), including the
    Company, completed a transaction to form and capitalize a new entity,
    which will continue to use the ARIA Wireless Systems, Inc. name (New ARIA).
    New ARIA will succeed to the commercial telecommunications business of old
    ARIA.  As a result of this transaction, New ARIA will control all aspects
    of engineering, manufacturing, marketing and sale of the DataMover(R) and
    other related products.  Previously these activities were split between
    Comptek Telecommunications, Inc. (CTI), a subsidiary of the Company, and
    old ARIA.

    As its part of this transaction, the Company contributed the following net
assets of CTI to New ARIA:

                                  (UNAUDITED)





    In return for the contribution of these net assets, the Company received:
    4,900 shares of New ARIA's Class A - voting common stock (representing 49%
    of outstanding voting common stock); 1,853 shares of New ARIA's Class CR-I
    preferred stock with a 15% cumulative dividend, a $1,000 per share face
    value and liquidation preference and  a mandatory redemption provision
    whereby the Company, as holder of the shares, may require New ARIA to
    redeem the shares for face value at the earlier of five years or an initial
    public offering of New ARIA's stock; 48,951 shares of New ARIA's Class
    CR-II preferred stock with no dividend or mandatory redemption feature but
    with a $101.52 per share liquidation preference and face value.  These
    shares are convertible, at the option of the holder, into 4,895,100 shares
    of Class B - limited-voting common stock.  The New ARIA certificate of
    incorporation provides, among other things, for full voting rights to vest
    in the Class B shares at the time of an initial public offering of New
    ARIA's common stock.

    The Company's initial investment in New ARIA is equal to the Company's pro
    rata share of New ARIA's shareholders' equity.  The difference between the
    book value of the net assets contributed and the initial investment balance
    has been allocated to goodwill, which is included in "Investment in ARIA
    Wireless Systems, Inc." on the Company's Balance Sheet, and will be
    amortized over a five year period.  The Company will evaluate its aggregate
    investment on an ongoing basis by reference to New ARIA's actual and
    projected cash flows.  The Company accounts for its investment in New ARIA
    under the equity method of accounting.  In applying the equity method of
    accounting, the Company utilizes a measure of its economic contribution
    percentage in determining its recordable share of New ARIA losses.  Its
    percentage of economic contribution is generally calculated based on the
    ratio of assets contributed by the Company to the total initial
    capitalization of New ARIA.  Upon New ARIA's attainment of profitable
    operations, the Company will record its share of earnings at the same
    percentage until such time as the Company's investment balance is restored
    to an amount equal to its pro rata share of New ARIA's underlying equity.

    Subsequent to the end of the first quarter the Company raised approximately
    $500,000 through a sale of 28,249 shares of treasury stock in a private
    transaction.  Additionally, subsequent to quarter end the Company purchased
    from ARIA 12% senior subordinated notes in the principal amount of
    $1,000,000 and providing for warrants to purchase up to 160,000 Class B
    common shares of ARIA .  This purchase was part of ARIA's private placement
    of notes in the aggregate principal amount of $3,000,000 with warrants to
    purchase up to 480,000 shares.

    Condensed results of ARIA Wireless Systems, Inc. (for the quarter ended
    June 30, 1995) is as follows (in thousands):

             Net sales                                $    2,003
             Gross profit                                    736
             Net loss                                        (78)

                          Independent Auditor's Report
                          ----------------------------

The Board of Directors and Shareholders
Comptek Research, Inc.:


We have reviewed the consolidated condensed balance sheet of Comptek Research,
Inc. and subsidiaries as of June 30, 1995, and the related consolidated
condensed statements of operations, shareholders' equity, and cash flows for
the three month periods ended June 30, 1995, and July 1, 1994. These
consolidated condensed financial statements are the responsibility of the
Company's management.

We conducted our review in accordance with standards established by the
American Institute of Certified Public Accountants.  A review of interim
financial information consists principally of applying analytical procedures to
financial data, and making inquiries of persons responsible for financial and
accounting matters. It is substantially less in scope than an audit in
accordance with generally accepted auditing standards, the objective of which
is the expression of an opinion regarding the financial statements taken as a
whole.  Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the consolidated condensed financial statements referred to above
for them to be in conformity with generally accepted accounting principles.

We have previously audited, in accordance with generally accepted auditing
standards, the consolidated balance sheet of Comptek Research, Inc. and
subsidiaries as of March 31, 1995, and the related consolidated statements of
operations shareholders' equity, and cash flows for the year then ended (not
presented herein); and in our report dated May 9, 1995, except as to note 13
which is as of May 31, 1995, we expressed an unqualified opinion on those
consolidated financial statements.   Our report also contained an explanatory
paragraph referring to an uncertainty as to the ultimate outcome of an
arbitration proceeding involving a Company subsidiary and its investee which
seeks approximately $7.2 million in damages.  In our opinion, the information
set forth in the accompanying consolidated condensed balance sheet as of March
31, 1995, is fairly stated, in all material aspects, in relation to the
consolidated balance sheet from which it has been derived.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS



FINANCIAL CONDITION
- -------------------

During the first quarter of fiscal  year 1996, the Company used its
available revolving credit primarily to fund increases in inventories for the
Commercial Systems and Service Segment and the purchase of equipment.  Although
the Company currently anticipates positive cash flow from operations for fiscal
1996, first quarter operating activities resulted in a net use of cash of 
$679,000.  On June 6, 1995, the Company completed a previously announced
transaction providing for the transfer of substantially all of the operating
assets of the Company's Commercial Systems and Service Segment to a recently
formed Delaware corporation known as ARIA Wireless Systems, Inc. (ARIA).  In
return for the contributed assets, the Company and its subsidiaries received 49%
of the voting common stock of ARIA, two series of preferred stock, and certain
other rights.  This transaction resulted in the contribution of approximately
$6.9  million of certain commercial assets which represents changes in certain
items on the consolidated condensed balance sheet including accounts
receivables, inventories, and net equipment and leasehold improvements.  The
Company recorded a corresponding increase in its investment in ARIA, as an
equity-investee.  From that point forward the operations of the former
Commercial Systems Segment have been transferred to ARIA and will be accounted
for under the equity method of accounting.

Subsequent to the end of the first quarter the Company raised approximately
$500,000 through a sale of 28,249 shares of treasury stock in a private
transaction.  Additionally, subsequent to quarter end the Company purchased
from ARIA 12% senior subordinated notes in the principal amount of $1,000,000
and providing for warrants to purchase up to 160,000 Class B common shares of
ARIA.  This purchase was part of ARIA's private placement of notes in the
aggregate principal amount of $3,000,000 with warrants to purchase up to
480,000 shares.

The Company anticipates cash flow from operations and available funds from the
revolving credit agreement to be sufficient to satisfy operational and capital
expenditures needs of the Company for the remainder of the fiscal year.



RESULTS OF OPERATIONS
- ---------------------

Net sales decreased by $2,083,000, or 14.7%, in the first quarter of 1996 as
compared with the first quarter 1995.  This decrease was primarily due to two
reasons: (i) the transfer to ARIA discussed above and (ii) the Company's
Defense Systems and Service Segment experienced lower than normal activity in
subcontractor work on a U.S. Navy contract for Electronic Combat Mission
Support (ECMS).  The Company anticipates the level of subcontractor activity to
improve over the remainder of fiscal year 1996.  Backlog at the end of the
quarter was $56.3 million consisting entirely of Defense Segment contracts, an
increase of 5.6% from $53.3 million at March 31, 1995, for that segment.

Gross margin percentage (net sales minus cost of sales) increased to 16.4%
compared with 14% in the prior year.  This is attributable to reduced ECMS
subcontractor work, which typically provides relatively low profit margins,
coupled with the removal of the Commercial business from the Company's
operations.  Gross margin percentage will be affected in future quarters as
subcontractor work increases on the ECMS contract; in contrast the combination
of the Company's Commercial business with ARIA is a permanent impact.

Selling, General and Administrative expense as a percent of sales increased
during the first quarter primarily as a result of the lower sales base for the
quarter.  S,G&A dollars increased by $74,000 as compared with the first quarter
1995 due to expanded marketing activities.

Research and Development (R&D) spending increased 1% over the first quarter
1995 and shifted from the Commercial Segment to the Defense Segment.  Defense
Segment spending increased to $242,000 from $82,000 in the prior year.
Increases in this Segment's spending is associated with the participation, in a
development project with the U.S. government.  The Segment anticipates spending
approximately the same amount for each of the remaining quarters of the fiscal
year 1996.  A corresponding decrease in R&D spending was realized as a result
of the combination of the Commercial Segment with ARIA.  Overall R&D spending
will likely decrease in fiscal 1996 as compared to fiscal 1995.

The Company recorded $78,000 loss for the first quarter from its equity
investment in ARIA.  The combination which was completed June 6, 1995,
effective for financial statement purposes as of May 31, 1995, resulted in the
Company reporting, as of June 1, 1995, all of the commercial telecommunications
business activities through the equity method of accounting.

       ii.  In the event that the Participant shall cease to be employed by the
            Company or its subsidiaries by reason of retirement because of age,
            the Participant shall have the right to exercise the Option (to the
            extent exercisable and not previously exercised) within three (3)
            months after such termination of employment. Option installments

            (3) months after the termination of his employment with the Company 
            or its subsidiaries and at a time when an unexercised Option 
            theretofore granted to him has not terminated or expired, the 
            Option may be exercised (to the extent exercisable and not 
            previously exercised) within six (6) months after the Participant's
            death, by the executors or administrators of the Participant or by

           ISO shall not exceed $100,000.
 
       ii. Notwithstanding anything herein to the contrary, no ISO shall be
           granted to any individual if at the time the Option is to be granted

           total combined voting power of all classes of stock of the Company 
           unless at the time such Option is granted, the Option price is at 
           least 110 percent of the Fair Market Value of the stock subject to

            Option and such Option by its terms is not exercisable after the
            expiration of five years from the date such Option is granted.
 
      iii.  Notwithstanding anything herein to the contrary, the maximum number
            of Shares for which Options or LSARs may be issued to any individual
            in any one year period shall not exceed 125,000.
 
    f. Option Reload.  The Committee may with the grant of any Option provide
       that upon payment of the exercise price with shares of common stock that
       the Participant shall receive an additional number of Options of the same
       nature (i.e., ISOs or NonQualified Stock Options) equal to the number of
       shares of common stock surrendered in payment (provided the aggregate
       Plan limits shall not be exceeded). Such additional Options shall be
       exercisable at the current Fair Market Value of the common stock on the
       date of grant hereunder and subject to such other terms as the Committee
       shall establish.
 
    g. Other Terms.  Each ISO agreement shall contain such other terms,
       conditions and provisions as the Committee my determine to be necessary
       or desirable in order to qualify such Option as a tax-favored Option
       within the meaning of Section 422 of the Code, or any amendment thereof,
       substitute therefor, or regulation thereunder. Subject to the limitations
       of Section 19, and without limiting any other provisions hereof, the
       Committee shall have the power without further approval to amend the
       terms of any Option.

terms and conditions:
 
    a. Award.  The Committee shall determine the amount of a Restricted Stock

       performance objectives, and for such period or periods as shall be
       determined by the Committee at the time of grant. The Committee shall
       have the power to permit, in its discretion, an acceleration of the
       expiration of the applicable restriction period with respect to any part
       or all of the award to any Participant.
 
    c. Restrictions Upon Transfer.  Shares awarded, and the right to vote such
       Shares and receive dividends thereon, may not be sold, assigned,
       transferred, exchanged, pledged, hypothecated, or otherwise encumbered,
       except as herein provided, during the restriction period applicable to
       such shares. Notwithstanding the foregoing, and except as otherwise
       provided in the Plan, the Participant shall have all the other rights of
       a stockholder including, but not limited to, the right to receive
       dividends and the right to vote such Shares.
 
    d. Certificates.  Each certificate issued with respect to the Restricted
       Stock Shares awarded to the Participant shall bear a legend stating, but

       will lapse, and the rights of the holder during the restricted period.

       conditions upon which any restrictions on the right to receive Shares
       representing Restricted Stock awarded under the Plan shall lapse, as
       determined by the Committee. Upon the lapse of such restrictions, Shares
       of common stock free of any restrictive legend shall be issued to the
       Participant of his legal representative.
 
    f. Termination Prior to Lapse of Restrictions.  In the event of a
       Participant's termination of employment for any reason prior to the lapse
       of restrictions applicable to a Restricted Stock Award made to such
       Participant, all rights to Shares as to which there still remain unlapsed
       restrictions shall be forfeited by such Participant to the Company
       without payment or any consideration by the Company, and neither the
       Participant nor any successors, heirs, assigns, or personal
       representatives of such Participant shall thereafter have any further
       rights or interest in such Shares.

    Performance Award Agreements in such form and not inconsistent with this
    Plan as the Committee shall approve from time to time, which Agreements
    shall contain in substance the following terms and conditions:
 
    a. Performance Period.  At the time the Award, the Committee shall establish
       with respect to each Award a performance period over which the Award may
       be earned.
 
    b. Award.  The Committee shall determine the amount and conditions under
       which a Performance Award will be granted to an eligible employee,
       including without limitation, the requirement that the Participant or the
       Company attain specific performance objectives for such period as shall
       be determined by the Committee at the time of grant. In determining the
       amount of the contingent Performance Award, the Committee shall take into
       account the financial objectives of the Company, including but not
       limited to sales and earnings, as well as the Participant's
       responsibility level, performance, potential, and other considerations as
       it deems appropriate.
 
    c. Form.  The Committee shall determine whether Performance Awards earned
       will be in the form of Shares of stock ("Performance Shares") or cash
       prior to the beginning of each Performance Period. A Participant may by
       irrevocable notice filed with the Company at least six months prior to
       completion of the performance period elect to have any anticipated award
       amount to be paid in cash paid in Shares of stock in lieu of cash.
 
    d. Payment of Award.  Following the conclusion of each Performance Period,
       the Committee shall determine the extent to which performance targets
       have been attained for such period as well as the other terms established
       by the Committee. Payment in cash or Performance Shares as determined by
       the Committee or as elected by the Participant, as the case may be,
       shall be made as promptly as practical following the end of the 
       Performance Period. The Committee may in the connection with the 
       payment of an Award in the form of Performance Shares grant to a 
       Participant a cash bonus equal to the federal and state income tax 
       liability anticipated to be incurred by such Participant upon receipt of
       Performance Shares.
 
    e. Adjustments.  At any time prior to the payment of the Awards, the
       Committee may adjust previously established performance targets and other
       terms and conditions, including the Company's financial performance for
       Plan purposes, to reflect major unforeseen events such as changes in
       laws, regulations or accounting practice, mergers, acquisitions or
       divestitures or extraordinary, unusual, or nonrecurring items or events.
 
    f. Termination Prior to Award Being Fully Earned.  A Performance Award
       granted to an employee shall terminate for all purposes if the
       Participant is not in the continuous employ of the Company at all times
       during the Performance Period, except in the case of death, disability,
       or retirement. A Participant or the Participant's estate whose employment
       was terminated due to death, disability or retirement shall be eligible
       to receive a pro rata portion of the payment of his Award based upon the
       portion of the Performance Period during which the Participant was
       employed, as the Committee shall determine in each case.
 
10. LIMITED STOCK APPRECIATION RIGHTS.
 
    a. The Committee is authorized, in its discretion, to grant LSARs with
       respect to all or any portion of the Shares covered by stock options
       granted hereunder to officers of the Company, simultaneously with the
       grant of, or at any time during the term of, Non-Qualified Options or
       simultaneously with the grant of ISOs. The grant of the LSAR will not be
       effective until six months after the date of its grant. Those Options
       with respect to which an LSAR has been granted and become effective shall
       become immediately exercisable upon the occurrence of any of the
       following events (each, a "Triggering Event"): (i) the consummation by
       the Company of a reorganization, merger, or consolidation after approval
       of any such transaction by shareholders, other than Section 16
       Participants, holding at least the minimum number of shares necessary to
       approve such transaction under the Company's Articles of Incorporation
       and applicable law, (ii) the consummation by the Company of a sale of
       substantially all its assets after approval of any such transaction by
       shareholders, other than Section 16 Participants, holding at least the
       minimum number of shares necessary to approve such transactions under the
 
                                       A-5
<PAGE>   7
       Company's Articles of Incorporation and applicable law, or (iii) the
       acquisition by a single purchaser or group of related purchasers of in
       excess of 51% of the issued and outstanding shares of common stock from
       shareholders of the Company other than Section 16 Participants, in any
       case other than in a transaction in which the surviving corporation or
       the purchaser is the Company or a subsidiary of the Company (other than a
       transaction in which the surviving corporation or the purchaser is the
       Company or a subsidiary of the Company but the capital stock of the
       Company or a subsidiary of the Company is converted into capital stock of
       any entity other than the Company or any such subsidiary) or an entity
       controlled by Section 16 Participants.
 
    b. The LSARs shall provide that upon the occurrence of any Triggering Event,
       the Participant shall receive from the Company, for each LSAR, an amount
       in cash equal to the amount by which the option exercise price per Share
       of the Option to which the LSAR relates exceeds the Fair Market Value of
       the Shares issuable upon exercise of such Option on the date such
       Triggering Event occurs. When a Triggering Event occurs, the Option to
       which the LSAR relates will cease to be exercisable, but will be deemed
       to have been exercised for purposes of determining the number of Shares
       for which Options may be granted hereunder.
 
    c. An LSAR shall be expressly subject to the following additional
       requirements: (i) the LSAR shall expire no later than the expiration of
       the underlying Option; (ii) the LSAR shall be transferable only when the
       underlying Option is transferable, and under the same conditions; and
       (iii) a Triggering Event shall be deemed to have occurred only when the
       Fair Market Value of the Shares subject to the underlying Option exceeds
       the exercise price of such option.
 
11. ACCELERATION OF VESTING.  Notwithstanding the provisions of Section 7 hereof
    and the terms of each Stock Option Agreement, upon he occurrence of any
    Triggering Event (as defined in Section 10 hereof) all Options, Restricted
    Stock, Performance Awards, and other applicable awards granted under the
    Plan, then unexercised and unexpired, shall become immediately vested and/or
    payable in cash for the period of their remaining terms automatically and
    without any action by the Committee.
 
12. LOANS.  The Committee may grant to a Participant a loan not to exceed the
    principal amount of $30,000 for the purpose of paying federal or state tax
    liability anticipated to be incurred by such Participant upon the exercise
    of an Option or receipt of Performance Shares. Such loan shall be subject to
    such conditions as the Committee shall determine at the time of grant
    thereof, including without limitation, interest and repayment terms.
 
13. GENERAL RESTRICTIONS.  The Plan and each Award under the Plan shall be
    subject to he requirement that, if at any time the Committee shall determine
    that (i) the listing, registration or qualification of the shares of common
    stock subject or related thereto upon any securities exchange or under any
    state or federal law, or (ii) the consent or approval of any government
    regulatory body, or (iii) an Agreement by the recipient of an Award with
    respect to the disposition of Shares of common stock, is necessary or
    desirable as a condition of, or in connection with, the Plan or the granting
    of such Award or the issue or purchase of Shares of common stock thereunder,
    such Plan will not be effective and the Award may not be consummated in
    whole or in part unless such listing, registration, qualification, consent,
    approval or agreement shall have been effected or obtained free of any
    conditions not acceptable to the Committee.
 
14. RIGHTS OF A SHAREHOLDER.  The recipient of any award under the Plan shall
    have no rights as a shareholder with respect thereto unless and until
    legended certificates for Shares of common stock are issued.
 
15. RIGHTS TO TERMINATE EMPLOYMENT.  Nothing in the Plan or in any Agreement
    entered into pursuant to the Plan shall confer upon any Participant the
    right to continue in the employment of the Company or affect any right which
    the Company may have to terminate the employment of such Participant.
 
16. WITHHOLDING OF TAXES.  Whenever the Company proposes or is required to issue
    or transfer Shares of common stock under the Plan, the Company shall have
    the right to require the recipient to remit to the Company an amount
    sufficient to satisfy any federal, state, and/or local withholding tax
    requirements prior to the delivery of any certificate or certificates for
    such Shares. Withholding requirements may be satisfied by cash payments or
    at the election of a Plan Participant by having the Company withhold a
    portion of the Shares to be received having a value equal to the amount to
    be withheld (or such portion
 
                                       A-6
<PAGE>   8
    thereof as the Participant may elect). Any election to have Shares withheld
    under this Section shall be subject to the following restrictions in
    accordance with Section 16(b) of the Securities Exchange Act of 1934, as
    amended:
 
    a. The election shall be made at the time of grant and shall be irrevocable;
 
    b. the election shall be subject, in whole or in part, to the approval of
       the Committee and to such rules as it may adopt; and
 
    c. the Option that may be part of the transaction must not be exercised
       within six months following the election.
 
       Whenever payments under the Plan are to be made in cash, such payments
       shall be net of an amount sufficient to satisfy any federal, state,
       and/or local withholding tax requirements.
 
17. NON-ASSIGNABILITY.  No Award under the Plan shall be assignable or
    transferable by the recipient thereof except by will or by the laws of
    descent and distribution or by such other means as the Committee may approve
    from time to time. During the life of the recipient, such Award shall be
    exercisable only by such person or by such person's guardian or legal
    representative.
 
18. NON-UNIFORM DETERMINATIONS.  The Committee's determinations under the Plan
    (including without limitation determinations of the persons to receive
    Awards, the form, amount, and timing of such Awards, the terms and
    provisions of such Awards and the Agreements evidencing same, and the
    establishment of values and performance targets) need not be uniform and may
    be made by it selectively among persons who receive, or are eligible to
    receive, Awards under the Plan, whether or not such persons are similarly
    situated.
 
19. ADJUSTMENTS.  In the event of any change in the outstanding common stock of
    the Company by reason of a stock dividend or distribution, recapitalization,
    merger, consolidation, split-up, combination, exchange of shares or the
    like, the Committee shall adjust he number of Shares of common stock which
    may be issued under the Plan and shall provide for an equitable adjustment
    of any outstanding Award or Shares issuable pursuant to an outstanding Award
    under this Plan.
 
20. DELEGATION.  The Committee may delegate to one or more officers or managers
    of the Company, or a committee of such officers or managers, the authority,
    subject to such terms and limitations as the Committee shall determine, to
    grant Awards to, or to cancel, modify, waive rights with respect to, alter,
    discontinue, suspend, or terminate Awards held by, Participants who are not
    officers or directors of the Company for purposes of Section 16 of the
    Securities Exchange Act of 1934, as amended.
 
21. AMENDMENT.  The Board of the Company may amend the Plan at any time, except
    that without shareholder approval, the Board may not increase the maximum
    number of shares which may be issued under the Plan (other than increases
    pursuant to Section 19 hereof), extend the period during which any Award may
    be exercised, extend the term of the Plan or change the price at which a
    Option may be granted. The termination or any modification or amendment of
    the Plan shall not, without the consent of a Participant, affect a
    Participant's rights under an Award previously granted. No amendment shall
    be made without shareholder approval if such approval is necessary to comply
    with applicable tax or regulatory requirements, including any requirements
    for exemptive relief under Section 16 of the Securities Exchange Act of
    1934, as amended.
 
22. EFFECT ON PRIOR PLAN.  Subject to shareholder approval of this Plan as
    elsewhere herein provided, the Prior Plan is hereby superseded and shall be
    of no further force and effect, subject to the following:
 
    a. All Options heretofore issued under the Prior Plan shall be taken into
       account for purposes of the aggregate limit of common shares subject to
       this Plan pursuant to Section 4 hereof;
 
    b. nothing in this Plan shall change the terms of any option heretofore
       granted under the Prior Plan in any respect that is adverse to any
       optionee or dilute or diminish the rights or privileges of any optionee
       with respect thereto; and
 
                                       A-7
<PAGE>   9
 
    c. the Committee shall have authority in its absolute discretion to
       determine if any terms of this Plan that may be more favorable to
       optionees than any terms of the Prior Plan, in respect of Options
       heretofore granted thereunder, shall apply to such Options, provided that
       any such determination shall be made on a non-discriminatory basis.
 
23. EFFECT ON OTHER PLAN.  Participation in this Plan shall not affect an
    employee's eligibility to participate in any other benefit or incentive plan
    of the Company and any Awards made pursuant to this Plan shall not be used
    in determining the benefits provided under any other plan of the Company
    unless specifically provided.
 
24. DURATION OF THE PLAN.  The Plan shall remain in effect until all Awards
    under the Plan have been satisfied by the issuance of Shares or the payment
    of cash, but no Award shall be granted more than ten years after the date
    the Plan is adopted by the Company.
 
25. FUNDING OF THE PLAN.  This Plan shall be unfunded. The Company shall not be
    required to establish any special or separate fund or to make any other
    segregation of assets to assure the payment of any Award under this Plan and
    payment of Awards shall be subordinate to the claims of the Company's
    general creditors.
 
26. SEVERABILITY.  If any provision of the Plan or any Award is or becomes or is
    deemed to be invalid, illegal, or unenforceable in any jurisdiction, or as
    to any Person or Award, or would disqualify the Plan or any Award under any
    law deemed applicable by the Committee, such provisions shall be construed
    or deemed amended to conform to applicable laws, or if it cannot be so
    construed or deemed amended without, in the determination of the Committee,
    materially altering the intent of the Plan or the Award, such provision
    shall be stricken as to such jurisdiction, Person, or Award, and the
    remainder of the Plan and any such Award shall remain in full force and
    effect. With respect to Section 16 Participants, transactions under this
    Plan are intended to comply with all applicable conditions of Rule 16b-3 or
    its successors under the Securities Exchange Act of 1934, as amended. To the
    extent any provision of this Plan or actions by the Compensation Committee
    fails to so comply, it shall be deemed null and void, to the extent
    permitted by law and deemed advisable by the Compensation Committee.
 
27. CONSTRUCTION.  Wherever any words are used in this Plan in the masculine
    gender, they shall be construed as though they were also used in the
    feminine gender in all cases where they would so apply, and wherever any
    words are used herein in the singular form they shall be construed as though
    they were also used in the plural form in all cases where they would so
    apply.
 
28. HEADINGS.  Headings are given to the Sections and subsections of the Plan
    solely as convenience to facilitate reference. Such headings shall not be
    deemed in any way material or relevant to the construction or interpretation
    of the Plan or any provision thereof.
 
29. GOVERNING LAW.  The validity, construction, and effect of the Plan and any
    rules and regulations relating to the Plan shall be determined in accordance
    with the laws of the State of New York and applicable Federal law.
 
30. EFFECTIVE DATE.  Subject to the provisions of Section 32, this Plan shall be
    effective on April 9, 1992.
 
31. TERM OF THE PLAN.  No award shall be granted under the Plan after March 31,
    2002, but unless otherwise expressly provided in the Plan or in an
    applicable Award Agreement, any Award theretofore granted may extend beyond
    such date.
 
32. APPROVAL OF SHAREHOLDERS.  Notwithstanding anything herein to the contrary,
    this Plan shall only be effective if it is approved by holders of a majority
    of the outstanding shares of common stock of the Company voting, in person
    or by proxy, at an Annual Meeting of Shareholders to be held in 1992.  The
    Plan was amended by the Board of Directors on May 19, 1995, subject to
    approval by the shareholders at the 1995 Annual Meeting.
