- ----------

(1) The rights of the optionees vest at various times over a four-year
period. While the options are fully exercisable upon grant, any shares
purchased by the optionee which do not vest prior to the termination of
the optionee's employment may be repurchased by Corsair at cost. In
accordance with the terms of the 1997 Stock Incentive Plan under which
the options were granted, all rights of the optionee will accelerate and
vest in full upon an acquisition of Corsair unless the options are
assumed or replaced by or Corsair's repurchase rights are assigned to
the acquiring corporation. Under the terms of the 1997 Stock Incentive
Plan, following any acquisition of Corsair in which the rights of the
optionees do not accelerate and vest in full, the rights of each
optionee shall accelerate and vest (or Corsair's repurchase rights will
lapse in the case of exercised options) with respect to one-half of the
then unvested shares if the employment of the optionee is involuntarily
terminated within one year of the acquisition.

(2) Corsair granted options to purchase a total of 1,433,350 shares to
employees in fiscal year 1999.

(3) The exercise price per share of options granted represented the fair
market value of the underlying shares of Common Stock on the dates the
respective options were granted as determined by the Board, considering
all relevant factors. The exercise price may be paid in cash or in
shares of Common Stock valued at fair market value on the exercise date.
The fair market value of shares of Common Stock is determined in
accordance with certain provisions of the 1997 Stock Incentive Plan
based on the closing selling price of a share of Common Stock on the
date in question on the Nasdaq National Market. If shares of the Common
Stock are neither listed or admitted to trading on any stock exchange
nor traded on the Nasdaq National Market, then the fair market value
shall be determined by the Plan Administrator after taking into account
such factors as the Plan Administrator shall deem appropriate.

(4) The 5% and 10% assumed annual rates of compounded stock price
appreciation are mandated by rules of the Commission. The price used for
computing this appreciation is the exercise price of the options, not
the price of Common Stock in this Offering. There is no assurance
provided to any Named Executive Officer or any other holder of Corsair's
securities that the actual stock price appreciation over the 10-year
option term will be at the assumed 5% or 10% levels or at any other
defined level.

(1) "Value realized" is calculated on the basis of the fair market value of
the Common Stock on the date of exercise minus the exercise price and
does not necessarily indicate that the optionee sold such stock, and
does not take into account that some of such shares are subject to
rights of repurchase on the part of Corsair which lapse at various times
over four years after the date of grant.

(2) The options are immediately exercisable; however, any shares purchased
upon exercise may be subject to rights of repurchase on the part of
Corsair which lapse at various times over four years after the date of
grant.

(3) "Value" is defined as fair market price of the Common Stock at fiscal
year-end ($8.125) less exercise price.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

None of the Compensation Committee members is an officer or employee of
Corsair. No interlocking relationship exists between the Corsair's Board or
Compensation Committee and the board of directors or compensation committee of
any other company, nor has such an interlocking relationship existed in the
past.

EMPLOYMENT AND CHANGE OF CONTROL ARRANGEMENTS

Options granted to Named Executive Officers are immediately exercisable;
however, any shares purchased upon exercise are subject to rights of repurchase
on the part of Corsair that generally expire over four or five years from the
date of option grant. In accordance with the terms of the 1996 Stock
Option/Stock Issuance Plan and the 1997 Officer Stock Option Plan under which
options were granted to Named Executive Officers, all of the Named Executive
Officers' options will immediately vest and Corsair's repurchase rights will
immediately lapse with respect to shares held by the Named Executive Officers
upon an acquisition of Corsair, unless the options are assumed or replaced by,
or Corsair's repurchase rights are assigned to, the acquiring entity. Following
any acquisition of Corsair in which options remain subject to vesting and
repurchase rights do not lapse in the manner provided above, 50% of a Named
Executive Officer's options will vest and the repurchase rights with respect to
50% of such Named Executive Officer's shares will lapse if the employment of the
Named Executive Officer is involuntarily terminated within 18 months of the
acquisition.

Notwithstanding anything to the contrary set forth in Corsair's previous
filing under the Securities Act of 1933, as amended (the "Securities Act"), or
the Securities and Exchanges Act of 1934, as amended (the "Exchange Act"), that
might incorporate future filings, including this Proxy Statement, in whole or in
part, the following report and the Performance Graph on page 17 shall not be
incorporated into any such filings.

BOARD COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

The Compensation Committee presents this report regarding compensation
for Corsair's executive officers and the Chief Executive Officer of Corsair.

GENERAL COMPENSATION POLICY. Corsair's primary objective is to maximize
the value of Corsair's shares over time. Accomplishing this objective requires
achieving specific Company milestones and developing and ultimately marketing
superior products that provide cost-effective solutions for the wireless
communications industry. The overall goal of the Compensation Committee is to
develop compensation practices that will allow Corsair to attract and retain the
people needed to create, develop, manufacture and market such products.

Corsair compensates its executive officers with a combination of salary
and incentives designed to focus and balance their efforts on maximizing both
the near-term and long-term financial performance of Corsair. In addition,
Corsair's compensation structure rewards individual performance that furthers
Company goals. Elements of each officer's compensation include the following:

- Base Salary

- Annual Incentives

- Long-term Incentives

- Benefits

Each officer's compensation package is designed to provide an
appropriately weighted mix of these elements which cumulatively provides a level
of compensation roughly equivalent to that paid by companies of similar size and
complexity in similar industries.

BASE SALARY. Base salary and increases in base salary are determined by
individual performance and the salary levels in effect for companies of similar
size and complexity in similar industries. The Compensation Committee attempts
to keep the base salaries of Corsair's officers at a level broadly in line with
the median of the salaries of officers in comparative companies. The
Compensation Committee also evaluates individual experience and performance and
specific issues particular to Corsair, such as success in raising capital,
creation of stockholder value and achievement of specific Company milestones.
Certain of the companies contained in the survey on which this Compensation
Committee relied are included in the indices used to compare shareholder returns
in the Stock Performance Graph.

ANNUAL INCENTIVES. Annual Incentives are paid in accordance with an
annual Incentive Compensation Plan. Bonus awards are set at a level competitive
among peer group companies and early-stage high growth technology companies.
Potential cash incentive compensation paid under this plan is set as a
significant percentage of each officers' base salary. All of the incentive
compensation is directly tied to performance and is at risk. Each officer earns
incentive compensation based upon a mix of Company performance and personal
performance. Company performance is measured by achievement of specific Company
milestones. Compensation for personal performance under this plan is awarded by
the Compensation Committee based upon both an objective and subjective
evaluation of the performance of each officer. No incentive compensation is paid
for Company performance or personal performance unless specific Company and
individual goals are achieved during the fiscal year.

LONG-TERM INCENTIVE. Long-term incentive compensation in the form of
stock options is expected to be the largest element of total compensation over
time. Grants of stock options are designed to align the long-term interests of
each officer with the long-term interests of Corsair and its stockholders. Stock
options provide each officer with a significant incentive to manage Corsair from
the perspective of an owner with an equity stake in the business. The size of
the option grant to each officer is based on the officer's current and expected
future contributions to the business and vesting position. Awards of stock
options are designed to have an expected aggregate exercise value over time
equal to a multiple of salary which will create a significant opportunity for
stock ownership, motivation to remain with Corsair and incentive to increase
stockholder value.

BENEFITS. Benefits offered to Corsair's officers serve as a safety net
of protection against the financial catastrophes that can result from illness,
disability or death. Benefits offered to Corsair's officers are substantially
the same as those offered to all Corsair's regular employees.

CEO COMPENSATION

In setting compensation payable to Corsair's Chief Executive Officers,
Mr. Meyer and Ms. Byrnes, we have sought to be competitive with companies of
similar size and complexity in similar industries. The CEO's incentive
compensation under Corsair's annual Incentive Compensation Plan is entirely
dependent upon Corsair's performance and our evaluation of his or her personal
contribution to Corsair's performance. No incentive compensation is paid to the
CEO unless progress is made toward specific Company goals or these goals are
achieved during the fiscal year.

COMPLIANCE WITH INTERNAL REVENUE CODE SECTION 162(M). Section 162(m) of
the Internal Revenue Code, enacted in 1993, generally disallows a tax deduction
to publicly-held companies for compensation paid to certain executive officers,
to the extent that compensation exceeds $1 million per officer in any year. The
compensation paid to Corsair's executive officers for the 1999 fiscal year did
not exceed the $1 million limit per officer, and it is not expected the
compensation to be paid to Corsair's executive officers for the 2000 fiscal year
will exceed that limit. In addition, the Plan is structured so that any
compensation deemed paid to an executive officer in connection with the exercise
of his or her outstanding options under the Plan with an exercise price per
share equal to the fair market value per share of the Common Stock on the grant
date will qualify as performance-based compensation which will not be subject to
the $1 million limitation. Because it is very unlikely that the cash
compensation payable to any of Corsair's executive officers in the foreseeable
future will approach the $1 million limit, the Compensation Committee has
decided at this time not to take any other action to limit or restructure the
elements of cash compensation payable to Corsair's executive officers. The
Compensation Committee will reconsider this decision should the individual
compensation of any executive officer ever approach the $1 million level.

We conclude our report with the acknowledgement that no member of the
Compensation Committee is a current officer or employee of Corsair or any of its
subsidiaries.

Submitted by the Compensation Committee of Corsair's Board of Directors.

PERFORMANCE GRAPH

The following graph compares total stockholder returns since Corsair
became a reporting company under the Exchange Act to the Nasdaq CRSP Total
Return Index ("Nasdaq Broad Index") for the Nasdaq Stock Market (U.S. Companies)
and the Nasdaq Computer Data and Processing Index ("Nasdaq Computer Index"). The
total return for each of Corsair's Common Stock, the Nasdaq Broad Index and the
Nasdaq Computer Index assumes the reinvestment of dividends, although dividends
have not been declared on Corsair's Common Stock. The companies comprising the
Nasdaq Computer Index are available upon written request to Investor Relations
at Corsair's executive offices. The stockholder return shown on the graph below
is not necessarily indicative of future performance and Corsair will not make or
endorse any predictions as to future stockholder returns.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

In November 1996, Corsair made a loan in the amount of $200,000 bearing
interest at the rate of 7% per annum to Mary Ann Byrnes, the President and Chief
Executive Officer of Corsair, which loan was represented by a promissory note
and was secured pursuant to a pledge agreement by 370,101 shares of Common Stock
of Corsair held by Ms. Byrnes. Ms. Byrnes has repaid the principal and interest
due under this note and Corsair has released the pledged shares.

In addition to the indemnification provisions contained in Corsair's
Restated Certificate of Incorporation and Bylaws, Corsair has entered into
separate indemnification agreements with each of its directors and officers.
These agreements require Corsair, among other things, to indemnify such director
or officer against expenses, including attorneys' fees, judgments, fines and
settlements, or Liabilities, paid by such individual in connection with any
action, suit or proceeding arising out of such individual's status or service as
a director or officer of Corsair other than Liabilities arising from willful
misconduct or conduct that is knowingly fraudulent or deliberately dishonest.
These agreements also require Corsair to advance expenses incurred by such
individual in connection with any proceeding against such individual with
respect to which such individual may be entitled to indemnification by Corsair.

All future transactions between Corsair and its officers, directors,
principal stockholders and affiliates will be approved by a majority of the
independent and disinterested members of the Board of Directors, and will be on
terms no less favorable to Corsair than could be obtained from unaffiliated
third parties.

COMPLIANCE WITH SECTION 16(a) OF THE EXCHANGE ACT

The members of the Board of Directors, the executive officers of Corsair
and persons who hold more than 10% of Corsair's outstanding Common Stock are
subject to the reporting requirements of Section 16(a) of the Securities
Exchange Act of 1934 which require them to file reports with respect to their
ownership of the Common Stock and their transactions in such Common Stock. Based
solely on a review of the copies of such reports furnished to Corsair, or
written representations that no Form 5s were required, Corsair believes that,
during the period from January 1, 1999 through December 31, 1999, all reporting
requirements under Section 16(a) were met in a timely manner by its directors,
executive officers and greater than ten percent beneficial owners.
