      At the annual meeting, stockholders will vote on (a) the election of seven
(7) directors to serve until the 2001 annual meeting of stockholders and until
their successors shall be elected and qualified, (b) the approval of BDO
Seidman, LLP, as our independent auditors for the year ending December 31, 2000,

      We encourage you to review the detailed discussion presented in this proxy

annual meeting.

Record Date; Outstanding Shares; Voting Rights and Proxies

      Stockholders of record at the close of business on April 25, 2000, are
entitled to notice and to vote at the annual meeting. As of the close of
business on the record date, there were 9,760,402 shares of our common stock
outstanding. You are entitled to one vote for each share you own of record on
the record date.

      The presence in person or by proxy of holders of a majority of the shares
of common stock entitled to be voted will constitute a quorum for the
transaction of business at the annual meeting. If you file a proxy or attend the
annual meeting, your shares are counted as being present at the annual meeting
for purposes of determining whether there is a quorum, even if you abstain from
voting on all matters. The vote required for the election of directors and
approval of other proposals is set forth in the discussion of each proposal.

      You are requested to complete, sign, date and return the enclosed proxy
without delay in order to ensure that your shares are voted at the annual
meeting. The return of a signed proxy will not affect your right to attend the
annual meeting and vote in person. If you give a proxy, you have the right to
revoke it at any time before it is exercised by executing and returning a proxy
bearing a later date, by giving a written notice of revocation to our corporate
secretary, or by attending the annual meeting and voting in person. There is no
required form for a proxy revocation. All properly executed proxies not revoked
will be voted at the annual meeting in accordance with the instructions
contained therein.

      If you sign and return a proxy, but make no specification with respect to
any or all of the proposals listed therein, the shares represented by such proxy
will be voted for all the proposals, including the election of directors.
Abstentions and broker non-votes are not counted as votes "for" or "against" a
proposal. Where the affirmative vote on a proposal is required for approval,
abstentions and broker non-votes are counted in determining the number of shares
present or represented.

Cost of Solicitation

      We will bear the costs of soliciting proxies. In addition to the
solicitation of proxies by mail, our directors, officers and employees, who will
receive no compensation in addition to their regular salary, may solicit proxies
by mail, telecopier, telephone or personal interview. We will request that
brokers and other custodians, nominees and fiduciaries forward proxy material to
the beneficial holders of common stock held of record by such persons, where
appropriate, and will, upon request, reimburse such persons for their reasonable
out-of-pocket expenses incurred in connection therewith.

      Our board of directors has three committees: the executive committee, the
audit committee, and the compensation committee. The executive committee may
exercise the power and authority of the board in the management of our business
and affairs, to the maximum extent permitted by the Delaware General Corporation
Law, when necessary between meetings of the board.

      The audit committee is charged with the following responsibilities:

      o     Recommend to the board the selection of the independent accountants.
      o     Review the scope of the audit with the independent accountants.
      o     Review the annual and quarterly financial statements with the
            independent accountants prior to the filing of the Form 10-K and
            10-Q.
      o     Review any issues relating to the independence of the independent
            accountants.
      o     Review with the independent accountants and the board of directors
            any matters raised in any management letters issued by the
            independent accountants.
      o     Review any material transactions between us and any of its officers
            and directors, other than employment agreements and other matters
            which are subject to approval of the compensation committee or any
            stock option committee.

      The compensation committee, which also serves as the stock option
committee pursuant to stock option plans, reviews and approves compensation for
officers. The compensation committee also reviews the elements our variable
compensation plans.

      The executive committee is comprised of Messrs. Carney, Esanu, Feldman,
Kreitman, Miller and Schreiber. The audit and compensation committees are
comprised of Messrs. Esanu, Feldman, Kreitman, Miller and Schreiber. Mr.
Kreitman is chairman of the audit committee and Mr. Feldman is chairman of the
compensation committee. Mr. Lloyd I. Miller, III has advised us that he does not
wish to stand for re-election.

      Excluding actions by unanimous written consent, during 1999 the board of
directors held six meetings, the audit committee held five meetings and the
compensation committee held two meetings. The executive committee did not hold
any meeting during 1999. Each of the nominees for director attended at least 75%
of the aggregate number of meetings of the board of directors and the committee
on which he served that were held during the period he served.

      The chairman and each director who is not an employee receives an annual
fee of $16,000 for serving as a director, and each chairman of a standing
committee of the board receives an additional annual fee of $3,000. Each
director also receives a fee of $1,200 for each board meeting and each committee
meeting attended.

</TABLE>

      We provide certain management employees with a supplemental management
compensation program which is designed to provide current and post-employment
benefits in the event of their retirement or death. The supplemental management
compensation program is comprised of a supplemental retirement income program
and an equity split-dollar insurance program. Our premium payments with respect
to Messrs. Carney and Gazzo are included in the summary compensation table under
"All Other Compensation."

      The supplemental retirement income program is intended to provide a
participating employee or his heirs or distributees with annual retirement
income equal to 50% of the employee's base salary in 1984. Payments


                                     - 7 -
<PAGE>

under the program are to be made for a period of 15 years following the earlier
of the employee's attaining age 65 or his or her death.

      Certain of our officers named in the summary compensation table or their
affiliates are parties to employment or other agreements providing for
compensation during and after their employment.

      Employment Agreements. We have entered into employment agreements with
Messrs. Carney, Wilkins, Bahlo, Kornfeld, Gazzo, and Lamb. The agreements
continue on a year-to-year basis, for January 1 of each year, unless terminated
on prior notice of not less than 120 days for Messrs. Carney, Wilkins, Bahlo and
Lamb, and 90 days for Messrs. Kornfeld and Gazzo. Salary is determined by the
board, except that the salary may not be reduced except as a part of a salary
reduction program applicable to all executive officers. Upon death or
termination of employment as a result of a disability, the officer or his estate
is to receive a payment equal to three months salary. Upon a termination without
cause, Mr. Carney is entitled to receive his then current salary for 36 months.
Messrs. Kornfeld, Tancredi and Gazzo are entitled to receive their then current
salary for six months plus one month for each full year of service up to a
maximum aggregate of 24 months. In the event that an executive is covered by an
executive severance agreement, including the salary continuation agreements (as
described below), which provides for payments upon termination subsequent to a
"change of control", the executive would be entitled to the greater of the
severance arrangements as described in this paragraph or the severance payments
under the executive severance agreements.

      Salary Continuation Agreements. We are party to salary continuation
agreements with Messrs. Carney, Kornfeld, Tancredi, Gazzo, and Lamb. The salary
continuation agreements provide that, in the event that a change of control
occurs and the executive's employment with us is subsequently terminated by us
other than for cause, death or disability, or is terminated by the executive as
a result of a substantial alteration in the executive's duties, compensation or
other benefits, the executive shall be entitled to the payment of an amount
equal to his monthly salary at the rate in effect as of the date of his
termination (or, if higher, as in effect immediately prior to the change in
control) plus the pro rata monthly amount of his most recent annual bonus paid
immediately before the change of control multiplied by 36 in the case of Mr.
Carney and 24 in the case of Messrs. Kornfeld, Tancredi, Gazzo and Lamb. For
purposes of the salary continuation agreements, a change of control is defined
as one which would be required to be reported in response to the proxy rules
under the Securities Exchange Act of 1934, as amended, the acquisition of
beneficial ownership, directly or indirectly, by a person or group of persons of
our securities representing 25% or more of the combined voting power of our then
outstanding securities, or, during any period of two consecutive years, if
individuals who at the beginning of such period constituted the board cease for
any reason to constitute at least a majority thereof unless the election of each
new director was nominated or ratified by at least two-thirds of the directors
then still in office who were directors at the beginning of the period. The
change of control must occur during the term of the salary continuation
agreement, which in each case is currently through December 31, 2000 and is
renewed automatically unless we give timely notice prior to January 1 of any
year of our election not to renew the agreement. If such a change of control
occurs during the effectiveness of the salary continuation agreement, any
termination of such covered employee during the 18 months following the change
of control will result in the payment of the compensation described above.

Stock Option Plans

      We have three stock option plans. In 1996, the board adopted and the
stockholders approved the 1996 stock option plan covering 100,000 shares of
common stock. In 1997, the board adopted and the stockholders approved an
amendment to the 1996 Plan increasing the number of shares of common stock
subject to the 1996 plan to 450,000. In 1998, the board adopted the 1998
non-qualified stock option plan covering 450,000 shares of Common Stock. In 1999
the board adopted and the stockholders approved the 1999 stock option plan
covering 400,000 shares of common stock. The 1996 plan provides for the grant of
incentive and nonqualified stock options, the 1998 plan provides for the grant
of nonqualified options and the 1999 plan provides for the grant of incentive
and nonqualified options. The 1996 plan also provides for an annual grant to
each non-management director of an option to purchase 2,000 shares of common
stock at the fair market value on the date of grant and provided each director
who was a non-management director on May 8, 1997 with an option to purchase
15,000 shares of common stock at the fair market value on such date. The 1998
plan provides each director who was a non-employee director on February 2, 1998
with an option to purchase 15,000 shares of common stock at $3.25 per share,
which was the fair market value per share of common stock on such date. The 1999
plan provides for an annual grant to each non-management director of an option
to purchase 5,000 shares of common stock at fair market value to the extent
annual options are not granted under the 1996 plan.

      As of April 30, 2000, 6,000 shares had been issued pursuant to the 1996
plan, and no shares had been issued pursuant to the 1998 or 1999 plan and
935,788 shares were subject to outstanding options under these plans. We also
granted options to purchase an aggregate of 125,000 shares of common stock to
officers which were not issued pursuant to any of the plans.

      We have another stock option plan, the 1986 stock option plan, pursuant to
which options to purchase 170,000 shares of common stock could be granted. The
1986 plan expired in March 1996. As of April 30, 2000, 3,000 shares of common
stock were subject to outstanding options pursuant to the 1986 plan.

      The following table sets forth information as to grants of options during
the year ended December 31, 1999 to each of the officers named in the summary
compensation table and the potential realizable value of the options at an
assumed annual rate of stock appreciation of 5% and 10%, respectively. Such
assumptions are made for purpose of making the computation for the following
table and does not constitute an estimate, prediction or projection of future
stock value. No stock appreciation rights ("SARs") were granted.

Report of the Compensation Committee

      The compensation committee for 1999 was comprised of Messrs. Warren H.
Esanu, Herbert H. Feldman, Mr. Lloyd I. Miller III, Stanley Kreitman and Robert
Schreiber. As part of its responsibilities, the committee meets to determine the
base salary of the senior executives for the next year and bonuses for the
current year. The committee also meets, from time to time, to determine whether
individual grants of stock options should be awarded to senior executives as
well as to other employees. In discharging these responsibilities, the committee
reviews our performance relative to our goals. In addition, with the assistance
of the chief executive officer, the committee reviews the individual performance
of the other senior executive officers. The committee also evaluates the
performance of the chief executive officer, as reflected in our financial
performance, to determine base salary and bonus. The committee subsequently
reports on its evaluation and compensation determinations to the other
non-employee directors.
