         Involvement in Certain Legal Proceedings

         In March 1993, the Resolution Trust Corporation ("RTC"), as receiver
for Nassau Savings and Loan Association ("Nassau"), filed a complaint for
damages against Mr. Nicolaides arising out of five loans ("Loans") made by
Nassau between 1982 and 1983 to five partnerships of which Mr. Nicolaides was
one of the general partners. Mr. Nicolaides also was a guarantor of such Loans.
On November 22, 1995, without admitting liability for the claims asserted, Mr.
Nicolaides settled the RTC action for $2,125,000. On March 10, 1997, in a
separate criminal action arising out of the Loans, which was filed in the United
States District Court for the District of New Jersey, Mr. Nicolaides agreed to
plead guilty to one count of bank fraud. The court sentenced Mr. Nicolaides to
three-years probation and required payment of a $250,000 fine. Mr. Nicolaides is
in compliance with the terms of his probation.

         Neither the RTC action nor the criminal action included any ban on Mr.
Nicolaides engaging in any type of business activity.

         Mr. Nicolaides is the spouse of Maria E. Nicolaides, who may be deemed
the indirect beneficial owner of approximately 30.1% of the Company's
outstanding Common Stock. See "Security Ownership of Certain Beneficial Owners
and Management."

         On July 28, 1999, Airadigm Communications Inc. filed for chapter 11
bankruptcy protection. Mr. Benson served as Chairman and Chief Executive Officer
of Airadigm Communications Inc. until his retirement on July 13, 1999.

         Arrangements with Respect to the Board of Directors

         The Company has entered into an agreement providing Gwynedd the right
to designate one director to the Board. Additionally, in the event the Board
consists of more than seven directors, Gwynedd, at its option, may designate one
additional director. Any designee's appointment will be subject to the exercise
by the Board of Directors of its fiduciary duties and the approval of the
Company's shareholders upon the expiration of any appointed term at the next
annual meeting of shareholders. Gwynedd's right to designate directors will
cease at such time as Gwynedd's equity interest in the Company drops below ten
percent of the outstanding shares of the Company's Common Stock. Mr. Ryan
currently serves as Gwynedd's designee.

         Section 16(a) Beneficial Ownership Reporting Compliance

         Under Section 16(a) of the Securities Exchange Act of 1934, the
Company's directors and officers and persons who are the beneficial owners of
more than 10% of the Common Stock are required to report their beneficial
ownership of Common Stock and any changes in that ownership to the Securities
and Exchange Commission (the "SEC"). Specific due dates for these reports have
been established, and the Company is required to report any failure to file by
these dates during 1999. The Company believes that all of these filing
requirements were satisfied by its directors and officers and by the beneficial
owners of more than 10% of the common stock, except that Mr. Ryan was late in
filing one report relating to his indirect pecuniary interest in an option
granted to the law firm of which he is a partner, and Messrs. Benson and
Flanigan were each late in filing one report relating to two exempt stock option
grants and one exempt stock option grant, respectively. In making the foregoing
statements, the Company has relied on copies of the reporting forms received by
it or the written representations from certain reporting persons that no Forms 5
(Annual Statements of Changes in Beneficial Ownership) were required to be filed
under the applicable rules of the SEC.

Item 11. EXECUTIVE COMPENSATION

         Compensation of Directors

         Each director of the Company who is not also an employee of the Company
or a Gwynedd designated director receives an annual fee of $12,000 and a fee of
$250 for each meeting (except telephonic meetings, in which case the fee is
$125) of the Board or a committee thereof attended plus reimbursement of
expenses incurred in attending meetings. During the fiscal year ended October
31, 1999, Mr. Ray, as Chairman of the Board, received an additional $5,000 per
month in directors' fees. No additional fee is paid for committee meetings held
the same day as Board meetings.

         Under the Company's Non-Employee Director Stock Option Plan (the
"Director Plan"), each director who is not also an employee of the Company or a
Gwynedd designated director automatically is granted annual options covering
4,000 shares of Common Stock under the Director Plan. On each anniversary of the
initial option granted hereunder, such person shall be granted an option to
purchase 4,000 shares of the Common Stock, or such lower number of shares as
shall be equal to the number of shares as shall then be available (if any) for
grant under this Director Plan divided by the number of persons who are to
receive an option on such anniversary.

         In June 1999, in recognition of extraordinary service, the Company
granted Mr. Benson a stock option covering 25,000 shares of Common Stock
exercisable at $3.50 per share, the then fair market value on the date of grant.
The option has a term of 10 years and is fully vested and exercisable.

         Compensation of Executive Officers

         The following summary compensation table sets forth all cash
compensation paid to the Company's current Chief Operating Officer, former Chief
Executive Officer, and former Chief Financial Officer during the Company's
fiscal years ended October 31, 1999, 1998 and 1997.

(1)  Generally, options become exercisable at cumulative annual rates of 20%,
     commencing one year from the date of grant, and expire ten years from the
     date of grant. Notwithstanding the foregoing, options are fully exercisable
     in the event of a change of control of the Company. Options generally will
     terminate three months after the date employment with the Company or a
     subsidiary terminates. During such three-month period, options may be
     exercised only for the number of shares eligible to be exercised on the
     date employment terminates.
(2)  The Grant Date Present Value on the date of grant was estimated using the
     Black-Scholes options pricing model with the following weighted average
     assumptions: no dividend yield; expected volatility of 83%; risk-free
     interest rate of 6.33%; expected option life of 7 years; and a forfeiture
     rate of 2%.

         The following table sets forth certain information concerning the
number of unexercised options and the value of unexercised options at the end of
the fiscal year ended October 31, 1999 held by the executive officers of the

         The Company had, in prior fiscal years, entered into various
transactions and arrangements with Dominion Group Limited, a Member Company of
Dominion Holdings or a corporation which previously carried on certain
activities of such entity (collectively, "Dominion"). Dominion was an investment

shareholders of Dominion are also the shareholders of Gwynedd. See "Security
Ownership of Management and Certain Beneficial Owners."

         During fiscal 1995 the Company's subsidiary, Digital Audio Limited,
manufactured certain products for CellTel Data Services, Inc. ("CellTel"), a
company in which Dominion owns a controlling interest. In October 1996 Numerex
invested $375,000 in Digital Audio Limited in return for an initial 10% equity
interest in CellTel. In 1999, Numerex had the right to put its initial equity
interest to Dominion and Dominion could call this interest for $500,000. In
October 1999 the parties exercised this right, and the Company received $500,000
from Gwynedd.

         Mr. Ryan is a partner in the law firm of Salisbury & Ryan. Salisbury &
Ryan provided legal services to the Company in 1999 and will continue to provide
such services during 2000. As partial consideration for such legal services, the
Company granted a stock option to Salisbury & Ryan covering 100,000 shares at an
exercise price of $3.50, the then fair market value of a share of stock on the
date of grant. The option has a term of ten years and was exercisable with
respect to 50% of the shares upon issuance. The option will be exercisable with
respect to the remaining 50% of the shares on the first anniversary of the date
of grant. In addition, Salisbury & Ryan charged the Company legal fees of
approximately $275,637.
