Item 4. Description of Securities

Not applicable.

Item 5. Interests of Named Experts and Counsel

Not applicable.

Item 6. Indemnification of Directors and Officers

(a) Section 145 of the Delaware General Corporation Law permits
indemnification of officers and directors of the Company under certain
conditions and subject to certain limitations. Section 145 of the Delaware
General Corporation Law also provides that a corporation has the power to
purchase and maintain insurance on behalf of its officers and directors against
any liability asserted against such person and incurred by him or her in such
capacity, or arising out of his or her status as such, whether or not the
corporation would have the power to indemnify him or her against such liability
under the provisions of Section 145 of the Delaware General Corporation Law.

(b) Article V, Section(B) of the Company's Amended and Restated
Certificate of Incorporation (the "Certificate of Incorporation") permits the
Company, to the extent permitted by applicable law, to provide indemnification
of its agents (including directors and officers) in excess of the
indemnification and advancement otherwise permitted by Section 145 of the
Delaware General Corporation Law, subject only to the limits imposed by
applicable Delaware law with respect to actions for breach of duty to the
Company, its stockholders, and others.

(c) Article VII, Section 1 of the Company's Amended and Restated Bylaws
(the "Bylaws") provides that the Company shall indemnify its directors and
executive officers to the fullest extent not prohibited by

II-1
<PAGE> 3

the General Corporation Law of Delaware. Article VII, Section 2 of the Bylaws
grants the Company the power to indemnify its other officers, employees and
other Agents as set forth in the Delaware General Corporation Law. Article VII,
Section 4 of the Bylaws provides that all expenses incurred by a director or
executive officer in defending any threatened proceeding for which
indemnification is authorized under the Bylaws will be paid by the Company in
advance of the final disposition of such action, suit or proceeding upon receipt
of an undertaking by or on behalf of such director or officer to repay such
amount if it is ultimately determined that he or she is not entitled to be
indemnified by the Company under the Bylaws or otherwise. Article VII, Section 7
of the Bylaws provides that the rights to indemnity under the Bylaws continue as
to a person who has ceased to be a director, officer, employee or agent and
inure to the benefit of the heirs, executors, and administrators of the person.

(d) As permitted by Section 102(b)(7) of the Delaware General
Corporation Law, Article V, Section (A) of the Certificate of Incorporation
provides that a director of the Company is not personally liable for monetary
damages or breach of fiduciary duty as a director, except for liability (i) for
any breach of the director's duty of loyalty to the Company or its stockholders,
(ii) for acts or omissions not in good faith or involving intentional misconduct
or a knowing violation of law, (iii) under Section 174 of the Delaware General
Corporation Law or (iv) for any transaction from which the director derived any
improper personal benefit.

(e) Pursuant to authorization provided under the Certificate of
Incorporation, the Company has entered into indemnification agreements with each
of its present and certain of its former directors. The Company has also entered
into similar agreements with certain of the Company's executive officers who are
not directors. Forms of such indemnification agreements entered into with the
Company's directors and officers are attached as Exhibits 10.49 and 10.50
respectively to the Company's Registration Statement on Form S-1 (No. 333-28519)
filed with the Commission on June 4, 1997, as amended through its effective
date. Generally, the indemnification agreements attempt to provide the maximum
protection permitted by Delaware law as it may be amended from time to time.
Moreover, the indemnification agreements provide for certain additional
indemnification. Under such additional indemnification provisions, however, an
individual will not receive indemnification for judgments, settlements or
expenses if he or she is found liable to the Company (except to the extent the
court determines he or she is fairly and reasonably entitled to indemnity for
expenses), for settlements not approved by the Company or for settlements and
expenses not approved by the court. The indemnification agreements provide for
the Company to advance to the individual any and all reasonable expenses
(including legal fees and expenses) incurred in investigating or defending any
such action, suit or proceeding. In order to receive an advance of expenses, the
individual must submit to the Company copies of invoices presented to him or her
for such expenses. Also, the individual must repay such advances upon a final
judicial decision that he or she is not entitled to indemnification.

(f) Article VII, Section 8 of the Bylaws authorizes the Company, upon
approval of its board of directors, to purchase insurance on behalf of any
person permitted to be indemnified by the Bylaws to the fullest extent permitted
by the Delaware General Corporation Law. The Company's board of directors has
approved the purchase of, and the Company has purchased, directors and officers
liability insurance by the Company on behalf of its directors and officers as
authorized by the Bylaws.

Item 9. Undertakings

1. The undersigned registrant hereby undertakes:

(a) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933 (the "1933 Act");

(ii) To reflect in the prospectus any facts or events arising after the
effective date of this registration statement (or the most recent
post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth
in this registration statement; and

(iii) To include any material information with respect to the plan of
distribution not previously disclosed in this registration statement or
any material change to such information in this registration statement;

provided, however, that paragraphs (a)(i) and (a)(ii) shall not apply if the
information required to be in a post-effective amendment by those paragraphs is
contained in periodic reports filed by the Company pursuant to Section 13 or
Section 15(d) of the 1934 Act that are incorporated by reference into this
registration statement.

(b) That, for the purpose of determining any liability under the 1933
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof; and

(c) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold upon the termination
of the offering.

2. The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the 1933 Act, each filing of the Company's
annual report pursuant to Section 13(a) or Section 15(d) of the 1934 Act (and,
where applicable, each filing of an employee benefit plan's annual report
pursuant to Section 15(d) of the 1934 Act) that is incorporated by reference in
this registration statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

3. The undersigned registrant hereby undertakes to deliver or cause to
be delivered with the prospectus, to each person to whom the prospectus is sent
or given, the latest annual report, to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the 1934 Act; and, where interim
financial information required to be presented by Article 3 of Regulation S-X is
not set forth in the prospectus, to deliver, or cause to be delivered to each
person to whom the prospectus is sent or given, the latest quarterly report that
is specifically incorporated by reference in the prospectus to provide such
interim financial information.

4. Insofar as indemnification for liabilities arising under the 1933 Act
may be permitted to directors, officers or controlling persons of the Company
pursuant to the foregoing provisions, or otherwise, the Company has been advised
that in the opinion of the Commission such indemnification is against public
policy as expressed in the 1933 Act and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the Company of expenses incurred or paid by a director, officer or
controlling person of the Company in the successful defense of any action, suit
or proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Company will, unless in the
opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the 1933 Act and
will be governed by the final adjudication of such issue.

Re: Corsair Communications, Inc. - Registration Statement for
Offering of 1,150,000 Shares of Common Stock

Ladies and Gentlemen:

We have acted as counsel to Corsair Communications, Inc., a Delaware
corporation (the "Company"), in connection with the registration on Form S-8
(the "Registration Statement") under the Securities Act of 1933, as amended, of
750,000 shares of common stock under the Company's 1997 Stock Incentive Plan
(the "Incentive Plan") and 400,000 shares of common stock under the Company's
1997 Employee Stock Purchase Plan (the "Purchase Plan") (collectively, the
"Shares").

This opinion is being furnished in accordance with the requirements of
Item 8 of Form S-8 and Item 601(b)(5)(i) of Regulation S-K.

We have reviewed the Company's charter documents and the corporate
proceedings taken by the Company in connection with the establishment and
amendment of the Incentive Plan and the Purchase Plan. Based on such review, we
are of the opinion that if, as and when the Shares are issued and sold (and the
consideration therefor received) in accordance with the Incentive Plan and the
Purchase Plan (including any stock option agreements or stock issuance
agreements or stock purchase agreements thereunder) and in accordance with the
Registration Statement, such Shares will be duly authorized, legally issued,
fully paid and nonassessable.

We consent to the filing of this opinion letter as Exhibit 5.1 to the
Registration Statement.

Exhibit 99.1

CORSAIR COMMUNICATIONS, INC.

1997 STOCK INCENTIVE PLAN

ARTICLE ONE

GENERAL PROVISIONS

I. PURPOSE OF THE PLAN

This 1997 Stock Incentive Plan is intended to promote the interests of
Corsair Communications, Inc., a Delaware corporation, by providing eligible
persons with the opportunity to acquire a proprietary interest, or otherwise
increase their proprietary interest, in the Corporation as an incentive for them
to remain in the service of the Corporation.

Capitalized terms shall have the meanings assigned to such terms in
the attached Appendix.

II. STRUCTURE OF THE PLAN

A. The Plan shall be divided into four separate equity programs:

- the Discretionary Option Grant Program under which eligible
persons may, at the discretion of the Plan Administrator, be granted options to
purchase shares of Common Stock,

- the Salary Investment Option Grant Program under which eligible
employees may elect to have a portion of their base salary invested each year in
special option grants,

- the Stock Issuance Program under which eligible persons may, at
the discretion of the Plan Administrator, be issued shares of Common Stock
directly, either through the immediate purchase of such shares or as a bonus for
services rendered the Corporation (or any Parent or Subsidiary), and

- the Automatic Option Grant Program under which eligible non-
employee Board members shall automatically receive option grants at periodic
intervals to purchase shares of Common Stock.

B. The provisions of Articles One and Six shall apply to all equity
programs under the Plan and shall govern the interests of all persons under the
Plan.

III. ADMINISTRATION OF THE PLAN

<PAGE> 2

A. Prior to the Section 12 Registration Date, the Discretionary Option
Grant and Stock Issuance Programs shall be administered by the Board. Beginning
with the Section 12 Registration Date, the Primary Committee shall have sole and
exclusive authority to administer the Discretionary Option Grant and Stock
Issuance Programs with respect to Section 16 Insiders and shall have sole and
exclusive authority to administer the Salary Investment Option Grant Program
with respect to all eligible individuals.

B. Administration of the Discretionary Option Grant and Stock Issuance
Programs with respect to all other persons eligible to participate in those
programs may, at the Board's discretion, be vested in the Primary Committee or a
Secondary Committee, or the Board may retain the power to administer those
programs with respect to all such persons. The members of the Secondary
Committee may be Board members who are Employees eligible to receive
discretionary option grants or direct stock issuances under the Plan or any
other stock option, stock appreciation, stock bonus or other stock plan of the
Corporation (or any Parent or Subsidiary).

C. Members of the Primary Committee or any Secondary Committee shall
serve for such period of time as the Board may determine and may be removed by
the Board at any time. The Board may also at any time terminate the functions of
any Secondary Committee and reassume all powers and authority previously
delegated to such committee.

D. Each Plan Administrator shall, within the scope of its
administrative functions under the Plan, have full power and authority (subject
to the provisions of the Plan) to establish such rules and regulations as it may
deem appropriate for proper administration of the Discretionary Option Grant,
Salary Investment Option Grant and Stock Issuance Programs and to make such
determinations under, and issue such interpretations of, the provisions of such
programs and any outstanding options or stock issuances thereunder as it may
deem necessary or advisable. Decisions of the Plan Administrator within the
scope of its administrative functions under the Plan shall be final and binding
on all parties who have an interest in the Discretionary Option Grant, Salary
Investment Option Grant and Stock Issuance Programs under its jurisdiction or
any option or stock issuance thereunder.

E. Service on the Primary Committee or the Secondary Committee shall
constitute service as a Board member, and members of each such committee shall
accordingly be entitled to full indemnification and reimbursement as Board
members for their service on such committee. No member of the Primary Committee
or the Secondary Committee shall be liable for any act or omission made in good
faith with respect to the Plan or any option grants or stock issuances under the
Plan.

F. Administration of the Automatic Option Grant Program shall be
self-executing in accordance with the terms of that program, and no Plan
Administrator shall exercise any discretionary functions with respect to any
option grants or stock issuances made under this program.

<PAGE> 3

IV. ELIGIBILITY

A. The persons eligible to participate in the Discretionary Option
Grant and Stock Issuance Programs are as follows:

(i) Employees,

(ii) non-employee members of the Board or the board of directors
of any Parent or Subsidiary, and

(iii) consultants and other independent advisors who provide
services to the Corporation (or any Parent or Subsidiary).

B. Only Employees who are Section 16 Insiders and other highly
compensated Employees shall be eligible to participate in the Salary Investment
Option Grant Program.

C. Each Plan Administrator shall, within the scope of its
administrative jurisdiction under the Plan, have full authority to determine,
(i) with respect to the option grants under the Discretionary Option Grant
Program, which eligible persons are to receive option grants, the time or times
when such option grants are to be made, the number of shares to be covered by
each such grant, the status of the granted option as either an Incentive Option
or a Non-Statutory Option, the time or times when each option is to become
exercisable, the vesting schedule (if any) applicable to the option shares and
the maximum term for which the option is to remain outstanding and (ii) with
respect to stock issuances under the Stock Issuance Program, which eligible
persons are to receive stock issuances, the time or times when such issuances
are to be made, the number of shares to be issued to each Participant, the
vesting schedule (if any) applicable to the issued shares and the consideration
for such shares.

D. The Plan Administrator shall have the absolute discretion either to
grant options in accordance with the Discretionary Option Grant Program or to
effect stock issuances in accordance with the Stock Issuance Program.

E. The individuals who shall be eligible to participate in the
Automatic Option Grant Program shall be limited to non-employee Board members
who are elected or appointed to the Board after the Effective Date. A non-
employee Board member who has previously been in the employ of the Corporation
(or any Parent or Subsidiary) shall not be eligible to receive an option grant
under the Automatic Option Grant Program at the time he or she first becomes a
non-employee Board member, but shall be eligible to receive periodic option
grants under the Automatic Option Grant Program while he or she continues to
serve as a non-employee Board member.

V. STOCK SUBJECT TO THE PLAN

<PAGE> 4

A. The stock issuable under the Plan shall be shares of authorized but
unissued or reacquired Common Stock, including shares repurchased by the
Corporation on the open market. The maximum number of shares of Common Stock
initially reserved for issuance over the term of the Plan is 3,337,633 shares of
Common Stock. Such share reserve includes an increase of 750,000 shares
authorized by the Board on March 25, 1999, subject to stockholder approval at
the 1999 Annual Meeting. On the first day of each calendar year, beginning with
the 1998 calendar year, the share reserve for the Plan will increase by an
amount equal to 2.0% of the shares of Common Stock outstanding on December 31 of
the immediately preceding calendar year. The additional shares will also require
registration with the SEC on a Form S-8 Registration Statement and may be used
only for the grant of non-statutory stock options.

B. No one person participating in the Plan may receive options,
separately exercisable stock appreciation rights and direct stock issuances for
more than 500,000 shares of Common Stock in the aggregate per calendar year,
beginning with the 1997 calendar year.

C. Shares of Common Stock subject to outstanding options (including
options incorporated into this Plan from the Predecessor Plans) shall be
available for subsequent issuance under the Plan to the extent those options
expire or terminate for any reason prior to exercise in full. Unvested shares
issued under the Plan and subsequently cancelled or repurchased by the
Corporation, at the original issue price paid per share, pursuant to the
Corporation's repurchase rights under the Plan shall be added back to the number
of shares of Common Stock reserved for issuance under the Plan and shall
accordingly be available for reissuance through one or more subsequent option
grants or direct stock issuances under the Plan. However, should the exercise
price of an option under the Plan be paid with shares of Common Stock or should
shares of Common Stock otherwise issuable under the Plan be withheld by the
Corporation in satisfaction of the withholding taxes incurred in connection with
the exercise of an option or the vesting of a stock issuance under the Plan,
then the number of shares of Common Stock available for issuance under the Plan
shall be reduced by the gross number of shares for which the option is exercised
or which vest under the stock issuance, and not by the net number of shares of
Common Stock issued to the holder of such option or stock issuance.

D. If any change is made to the Common Stock by reason of any stock
split, stock dividend, recapitalization, combination of shares, exchange of
shares or other change affecting the outstanding Common Stock as a class without
the Corporation's receipt of consideration, appropriate adjustments shall be
made to (i) the maximum number and/or class of securities issuable under the
Plan, (ii) the number and/or class of securities for which any one person may be
granted stock options, separately exercisable stock appreciation rights and
direct stock issuances under this Plan per calendar year, (iii) the number
and/or class of securities for which grants are subsequently to be made under
the Automatic Option Grant Program to new and continuing non-employee Board
members, (iv) the number and/or class of securities and the exercise price per
share in effect under each outstanding option under the Plan and (v) the number
and/or class of securities and price per share in effect under each outstanding
option incorporated into this Plan from

<PAGE> 5

the Predecessor Plans. Such adjustments to the outstanding options are to be
effected in a manner which shall preclude the enlargement or dilution of rights
and benefits under such options. The adjustments determined by the Plan
Administrator shall be final, binding and conclusive.

ARTICLE TWO

DISCRETIONARY OPTION GRANT PROGRAM

I. OPTION TERMS

Each option shall be evidenced by one or more documents in the form
approved by the Plan Administrator; provided, however, that each such document
shall comply with the terms specified below. Each document evidencing an
Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

A. EXERCISE PRICE.

1. The exercise price per share shall be fixed by the Plan
Administrator but shall not be less than eighty-five percent (85%) of the Fair
Market Value per share of Common Stock on the option grant date.

2. The exercise price shall become immediately due upon exercise of
the option and shall, subject to the provisions of Section I of Article Six and
the documents evidencing the option, be payable in one or more of the forms
specified below:

(i) cash or check made payable to the Corporation,

(ii) shares of Common Stock held for the requisite period
necessary to avoid a charge to the Corporation's earnings for financial
reporting purposes and valued at Fair Market Value on the Exercise Date, or

(iii) to the extent the option is exercised for vested shares,
through a special sale and remittance procedure pursuant to which the
Optionee shall concurrently provide irrevocable written instructions to (a)
a Corporation-designated brokerage firm to effect the immediate sale of the
purchased shares and remit to the Corporation, out of the sale proceeds
available on the settlement date, sufficient funds to cover the aggregate
exercise price payable for the purchased shares plus all applicable
Federal, state and local income and employment taxes required to be
withheld by the Corporation by reason of such exercise and (b) the
Corporation to deliver the certificates for the purchased shares directly
to such brokerage firm in order to complete the sale.

Except to the extent such sale and remittance procedure is utilized,
payment of the

<PAGE> 6

exercise price for the purchased shares must be made on the Exercise Date.

B. EXERCISE AND TERM OF OPTIONS. Each option shall be exercisable at
such time or times, during such period and for such number of shares as shall be
determined by the Plan Administrator and set forth in the documents evidencing
the option. However, no option shall have a term in excess of ten (10) years
measured from the option grant date.

C. EFFECT OF TERMINATION OF SERVICE.

1. The following provisions shall govern the exercise of any
options held by the Optionee at the time of cessation of Service or death:

(i) Any option outstanding at the time of the Optionee's
cessation of Service for any reason shall remain exercisable for such
period of time thereafter as shall be determined by the Plan Administrator
and set forth in the documents evidencing the option, but no such option
shall be exercisable after the expiration of the option term.

(ii) Any option exercisable in whole or in part by the Optionee
at the time of death may be subsequently exercised by the personal
representative of the Optionee's estate or by the person or persons to whom
the option is transferred pursuant to the Optionee's will or in accordance
with the laws of descent and distribution.

(iii) Should the Optionee's Service be terminated for Misconduct,
then all outstanding options held by the Optionee shall terminate
immediately and cease to be outstanding.

(iv) During the applicable post-Service exercise period, the
option may not be exercised in the aggregate for more than the number of
vested shares for which the option is exercisable on the date of the
Optionee's cessation of Service. Upon the expiration of the applicable
exercise period or (if earlier) upon the expiration of the option term, the
option shall terminate and cease to be outstanding for any vested shares
for which the option has not been exercised. However, the option shall,
immediately upon the Optionee's cessation of Service, terminate and cease
to be outstanding to the extent the option is not otherwise at that time
exercisable for vested shares.

2. The Plan Administrator shall have complete discretion,
exercisable either at the time an option is granted or at any time while the
option remains outstanding, to:

(i) extend the period of time for which the option is to
remain exercisable following the Optionee's cessation of Service from the
limited exercise period otherwise in effect for that option to such greater

<PAGE> 7

period of time as the Plan Administrator shall deem appropriate, but in no
event beyond the expiration of the option term, and/or

(ii) permit the option to be exercised, during the
applicable post-Service exercise period, not only with respect to the
number of vested shares of Common Stock for which such option is
exercisable at the time of the Optionee's cessation of Service but also
with respect to one or more additional installments in which the Optionee
would have vested had the Optionee continued in Service.

D. STOCKHOLDER RIGHTS. The holder of an option shall have no
stockholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become a
holder of record of the purchased shares.

E. REPURCHASE RIGHTS. The Plan Administrator shall have the discretion
to grant options which are exercisable for unvested shares of Common Stock.
Should the Optionee cease Service while holding such unvested shares, the
Corporation shall have the right to repurchase, at the exercise price paid per
share, any or all of those unvested shares. The terms upon which such repurchase
right shall be exercisable (including the period and procedure for exercise and
the appropriate vesting schedule for the purchased shares) shall be established
by the Plan Administrator and set forth in the document evidencing such
repurchase right.

F. LIMITED TRANSFERABILITY OF OPTIONS. During the lifetime of the
Optionee, Incentive Options shall be exercisable only by the Optionee and shall
not be assignable or transferable other than by will or by the laws of descent
and distribution following the Optionee's death. However, subject to the express
terms of the Option Agreement, a Non-Statutory Option may be assigned in whole
or in part during the Optionee's lifetime with the prior consent of the Plan
Administrator. The assigned portion may only be exercised by the person or
persons who acquire a proprietary interest in the option pursuant to the
assignment. The terms applicable to the assigned portion shall be the same as
those in effect for the option immediately prior to such assignment and shall be
set forth in such documents issued to the assignee as the Plan Administrator may
deem appropriate.

II. INCENTIVE OPTIONS

The terms specified below shall be applicable to all Incentive
Options. Except as modified by the provisions of this Section II, all the
provisions of Articles One, Two and Six shall be applicable to Incentive
Options. Options which are specifically designated as Non-Statutory Options when
issued under the Plan shall not be subject to the terms of this Section II.

A. ELIGIBILITY. Incentive Options may only be granted to Employees.

<PAGE> 8

B. EXERCISE PRICE. The exercise price per share shall not be less than
one hundred percent (100%) of the Fair Market Value per share of Common Stock on
the option grant date.

C. DOLLAR LIMITATION. The aggregate Fair Market Value of the shares of
Common Stock (determined as of the respective date or dates of grant) for which
one or more options granted to any Employee under the Plan (or any other option
plan of the Corporation or any Parent or Subsidiary) may for the first time
become exercisable as Incentive Options during any one calendar year shall not
exceed the sum of One Hundred Thousand Dollars ($100,000). To the extent the
Employee holds two (2) or more such options which become exercisable for the
first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.

D. 10% STOCKHOLDER. If any Employee to whom an Incentive Option is
granted is a 10% Stockholder, then the exercise price per share shall not be
less than one hundred ten percent (110%) of the Fair Market Value per share of
Common Stock on the option grant date, and the option term shall not exceed five
(5) years measured from the option grant date.

III. CORPORATE TRANSACTION/CHANGE IN CONTROL

A. In the event of any Corporate Transaction, each outstanding option
shall automatically accelerate so that each such option shall, immediately prior
to the effective date of the Corporate Transaction, become fully exercisable
with respect to the total number of shares of Common Stock at the time subject
to such option and may be exercised for any or all of those shares as
fully-vested shares of Common Stock. However, an outstanding option shall not so
accelerate if and to the extent: (i) such option is, in connection with the
Corporate Transaction, either to be assumed by the successor corporation (or
parent thereof) or to be replaced with a comparable option to purchase shares of
the capital stock of the successor corporation (or parent thereof), (ii) such
option is to be replaced with a cash incentive program of the successor
corporation which preserves the spread existing on the unvested option shares at
the time of the Corporate Transaction and provides for subsequent payout in
accordance with the same vesting schedule applicable to those option shares or
(iii) the acceleration of such option is subject to other limitations imposed by
the Plan Administrator at the time of the option grant. The determination of
option comparability under clause (i) above shall be made by the Plan
Administrator, and its determination shall be final, binding and conclusive.

B. All outstanding repurchase rights shall terminate automatically,
and the shares of Common Stock subject to those terminated rights shall
immediately vest in full, in the event of any Corporate Transaction, except to
the extent: (i) those repurchase rights are to be assigned to the successor
corporation (or parent thereof) in connection with such Corporate Transaction or
(ii) such accelerated vesting is precluded by other limitations imposed by the
Plan Administrator at the time the repurchase right is issued.

<PAGE> 9

C. Immediately following the consummation of the Corporate
Transaction, all outstanding options shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

D. Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments to reflect such Corporate Transaction shall also be made
to (i) the exercise price payable per share under each outstanding option,
provided the aggregate exercise price payable for such securities shall remain
the same, (ii) the maximum number and/or class of securities available for
issuance over the remaining term of the Plan and (iii) the maximum number and/or
class of securities for which any one person may be granted stock options,
separately exercisable stock appreciation rights and direct stock issuances
under the Plan per calendar year.

E. The Plan Administrator shall have full power and authority to grant
options under the Discretionary Option Grant Program which will automatically
accelerate in the event the Optionee's Service subsequently terminates by reason
of an Involuntary Termination within a designated period (not to exceed eighteen
(18) months) following the effective date of any Corporate Transaction in which
those options are assumed or replaced and do not otherwise accelerate. Any
options so accelerated shall remain exercisable for fully-vested shares until
the earlier of (i) the expiration of the option term or (ii) the expiration of
the one (1)-year period measured from the effective date of the Involuntary
Termination. In addition, the Plan Administrator may provide that one or more of
the Corporation's outstanding repurchase rights with respect to shares held by
the Optionee at the time of such Involuntary Termination shall immediately
terminate, and the shares subject to those terminated repurchase rights shall
accordingly vest in full.

F. The Plan Administrator shall have full power and authority to grant
options under the Discretionary Option Grant Program which will automatically
accelerate in the event the Optionee's Service subsequently terminates by reason
of an Involuntary Termination within a designated period (not to exceed eighteen
(18) months) following the effective date of any Change in Control. Each option
so accelerated shall remain exercisable for fully- vested shares until the
earlier of (i) the expiration of the option term or (ii) the expiration of the
one (1)-year period measured from the effective date of the Involuntary
Termination. In addition, the Plan Administrator may provide that one or more of
the Corporation's outstanding repurchase rights with respect to shares held by
the Optionee at the time of such Involuntary Termination shall immediately
terminate, and the shares subject to those terminated repurchase rights shall
accordingly vest in full.

G. The portion of any Incentive Option accelerated in connection with
a Corporate Transaction or Change in Control shall remain exercisable as an
Incentive Option only to the extent the applicable One Hundred Thousand Dollar
limitation is not exceeded. To the extent such dollar limitation is exceeded,
the accelerated portion of

<PAGE> 10

such option shall be exercisable as a Non-Statutory Option under the Federal tax
laws.

H. The outstanding options shall in no way affect the right of the
Corporation to adjust, reclassify, reorganize or otherwise change its capital or
business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.

IV. CANCELLATION AND REGRANT OF OPTIONS

The Plan Administrator shall have the authority to effect, at any time
and from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options under the Discretionary Option
Grant Program (including outstanding options incorporated from the Predecessor
Plans) and to grant in substitution new options covering the same or different
number of shares of Common Stock but with an exercise price per share based on
the Fair Market Value per share of Common Stock on the new grant date.

V. STOCK APPRECIATION RIGHTS

A. The Plan Administrator shall have full power and authority to grant
to selected Optionees tandem stock appreciation rights and/or limited stock
appreciation rights.

B. The following terms shall govern the grant and exercise of tandem
stock appreciation rights:

(i) One or more Optionees may be granted the right,
exercisable upon such terms as the Plan Administrator may establish, to
elect between the exercise of the underlying option for shares of Common
Stock and the surrender of that option in exchange for a distribution from
the Corporation in an amount equal to the excess of (a) the Fair Market
Value (on the option surrender date) of the number of shares in which the
Optionee is at the time vested under the surrendered option (or surrendered
portion thereof) over (b) the aggregate exercise price payable for such
shares.

(ii) No such option surrender shall be effective unless it
is approved by the Plan Administrator, either at the time of the actual
option surrender or at any earlier time. If the surrender is so approved,
then the distribution to which the Optionee shall be entitled may be made
in shares of Common Stock valued at Fair Market Value on the option
surrender date, in cash, or partly in shares and partly in cash, as the
Plan Administrator shall in its sole discretion deem appropriate.

(iii) If the surrender of an option is not approved by the
Plan Administrator, then the Optionee shall retain whatever rights the
Optionee had under the surrendered option (or surrendered portion thereof)

<PAGE> 11

on the option surrender date and may exercise such rights at any time prior
to the later of (a) five (5) business days after the receipt of the
rejection notice or (b) the last day on which the option is otherwise
exercisable in accordance with the terms of the documents evidencing such
option, but in no event may such rights be exercised more than ten (10)
years after the option grant date.

C. The following terms shall govern the grant and exercise of limited
stock appreciation rights:

(i) One or more Section 16 Insiders may be granted limited
stock appreciation rights with respect to their outstanding options.

(ii) Upon the occurrence of a Hostile Take-Over, each
individual holding one or more options with such a limited stock
appreciation right shall have the unconditional right (exercisable for a
thirty (30)-day period following such Hostile Take-Over) to surrender each
such option to the Corporation, to the extent the option is at the time
exercisable for vested shares of Common Stock. In return for the
surrendered option, the Optionee shall receive a cash distribution from the
Corporation in an amount equal to the excess of (A) the Take-Over Price of
the shares of Common Stock which are at the time vested under each
surrendered option (or surrendered portion thereof) over (B) the aggregate
exercise price payable for such shares. Such cash distribution shall be
paid within five (5) days following the option surrender date.

(iii) Neither the approval of the Plan Administrator nor the
consent of the Board shall be required in connection with such option
surrender and cash distribution.

(iv) The balance of the option (if any) shall remaining
outstanding and exercisable in accordance with the documents evidencing
such option.

ARTICLE THREE

SALARY INVESTMENT OPTION GRANT PROGRAM

I. OPTION GRANTS

The Primary Committee shall have the sole and exclusive authority to
determine the calendar year or years (if any) for which the Salary Investment
Option Grant Program is to be in effect and to select the Section 16 Insiders
and other highly compensated Employees eligible to participate in the Salary
Investment Option Grant Program for

<PAGE> 12

those calendar year or years. Each selected individual who elects to participate
in the Salary Investment Option Grant Program must, prior to the start of each
calendar year of participation, file with the Plan Administrator (or its
designate) an irrevocable authorization directing the Corporation to reduce his
or her base salary for that calendar year by an amount not less than Ten
Thousand Dollars ($10,000.00) nor more than Fifty Thousand Dollars ($50,000.00).
The Primary Committee shall have complete discretion to determine whether to
approve the filed authorization in whole or in part. To the extent the Primary
Committee approves the authorization, the individual who filed that
authorization shall be granted an option under the Salary Investment Grant
Program as soon as possible after the start of the calendar year for which the
salary reduction is to be in effect. All grants under the Salary Investment
Option Grant Program shall be at the sole discretion of the Primary Committee.

II. OPTION TERMS

Each option shall be a Non-Statutory Option evidenced by one or more
documents in the form approved by the Plan Administrator; provided, however,
that each such document shall comply with the terms specified below.

A. EXERCISE PRICE.

1. The exercise price per share shall be equal to the excess of
(i) the Fair Market Value of the Common Stock on the option grant date, over
(ii) the amount of the approved Salary Reduction divided by the number of shares
subject to the Option.

2. The exercise price shall become immediately due upon exercise
of the option and shall be payable in one or more of the alternative forms
authorized under the Discretionary Option Grant Program. Except to the extent
the sale and remittance procedure specified thereunder is utilized, payment of
the exercise price for the purchased shares must be made on the Exercise Date.

B. NUMBER OF OPTION SHARES. The number of shares of Common Stock
subject to the option shall be determined pursuant to the following formula
(rounded down to the nearest whole number):

X = A/(B x C), where

X is the number of option shares,

A is the dollar amount of the approved reduction in the
Optionee's base salary for the calendar year, B is the Fair
Market Value per share of Common Stock on the option grant date,
and

C is a percentage between 33 1/3% and 66 2/3% fixed by the Plan
Administrator, in its sole discretion, for purposes of the Salary

<PAGE> 13

Investment Option Grant Program with respect to options to be
granted during the current year of the Plan.

C. EXERCISE AND TERM OF OPTIONS. The option shall become exercisable
in a series of twelve (12) successive equal monthly installments upon the
Optionee's completion of each calendar month of Service in the calendar year for
which the salary reduction is in effect. Each option shall have a maximum term
of ten (10) years measured from the option grant date.

D. EFFECT OF TERMINATION OF SERVICE. Should the Optionee cease Service
for any reason while holding one or more options under this Article Three, then
each such option shall remain exercisable, for any or all of the shares for
which the option is exercisable at the time of such cessation of Service, until
the earlier of (i) the expiration of the ten (10)-year option term or (ii) the
expiration of the three (3)-year period measured from the date of such cessation
of Service. Should the Optionee die while holding one or more options under this
Article Three, then each such option may be exercised, for any or all of the
shares for which the option is exercisable at the time of the Optionee's
cessation of Service (less any shares subsequently purchased by Optionee prior
to death), by the personal representative of the Optionee's estate or by the
person or persons to whom the option is transferred pursuant to the Optionee's
will or in accordance with the laws of descent and distribution. Such right of
exercise shall lapse, and the option shall terminate, upon the earlier of (i)
the expiration of the ten (10)-year option term or (ii) the three (3)-year
period measured from the date of the Optionee's cessation of Service. However,
the option shall, immediately upon the Optionee's cessation of Service for any
reason, terminate and cease to remain outstanding with respect to any and all
shares of Common Stock for which the option is not otherwise at that time
exercisable.

III. CORPORATE TRANSACTION/CHANGE IN CONTROL

A. In the event of any Corporate Transaction while the Optionee
remains in Service, each outstanding option held by such Optionee under this
Salary Investment Option Grant Program shall automatically accelerate so that
each such option shall, immediately prior to the effective date of the Corporate
Transaction, become fully exercisable with respect to the total number of shares
of Common Stock at the time subject to such option and may be exercised for any
or all of those shares as fully-vested shares of Common Stock. Each such
outstanding option shall be assumed by the successor corporation (or parent
thereof) in the Corporate Transaction and shall remain exercisable for the
fully-vested shares until the earlier of (i) the expiration of the ten (10)-year
option term or (ii) the expiration of the three (3)-year period measured from
the date of the Optionee's cessation of Service.

B. In the event of a Change in Control while the Optionee remains in
Service, each outstanding option held by such Optionee under this Salary
Investment Option Grant Program shall automatically accelerate so that each such
option shall immediately become fully exercisable with respect to the total
number of shares of Common Stock at

<PAGE> 14

the time subject to such option and may be exercised for any or all of those
shares as fully-vested shares of Common Stock. Any options not exercised prior
to the Change in Control may be repurchased by the Corporation at the time of
the Change in Control at a repurchase price equal to the salary reduction
incurred in connection with the issuance of the option. Any option which is
neither exercised or repurchased shall remain so exercisable until the earlier
or (i) the expiration of the ten (10)-year option term or (ii) the expiration of
the three (3)-year period measured from the date of the Optionee's cessation of
Service.

C. The grant of options under the Salary Investment Option Grant
Program shall in no way affect the right of the Corporation to adjust,
reclassify, reorganize or otherwise change its capital or business structure or
to merge, consolidate, dissolve, liquidate or sell or transfer all or any part
of its business or assets.

IV. REMAINING TERMS

The remaining terms of each option granted under the Salary Investment
Option Grant Program shall be the same as the terms in effect for option grants
made under the Discretionary Option Grant Program.

ARTICLE FOUR

STOCK ISSUANCE PROGRAM

I. STOCK ISSUANCE TERMS

Shares of Common Stock may be issued under the Stock Issuance Program
through direct and immediate issuances without any intervening option grants.
Each such stock issuance shall be evidenced by a Stock Issuance Agreement which
complies with the terms specified below.

A. PURCHASE PRICE.

1. The purchase price per share shall be fixed by the Plan
Administrator, but shall not be less than one hundred percent (100%) of the Fair
Market Value per share of Common Stock on the issuance date.

2. Subject to the provisions of Section I of Article Six, shares
of Common Stock may be issued under the Stock Issuance Program for any of the
following items of consideration which the Plan Administrator may deem
appropriate in each individual instance:

(i) cash or check made payable to the Corporation, or

(ii) past services rendered to the Corporation (or any
Parent or Subsidiary).

<PAGE> 15

B. VESTING PROVISIONS.

1. Shares of Common Stock issued under the Stock Issuance Program
may, in the discretion of the Plan Administrator, be fully and immediately
vested upon issuance or may vest in one or more installments over the
Participant's period of Service or upon attainment of specified performance
objectives. The elements of the vesting schedule applicable to any unvested
shares of Common Stock issued under the Stock Issuance Program, namely:

(i) the Service period to be completed by the Participant or
the performance objectives to be attained,

(ii) the number of installments in which the shares are to
vest,

(iii) the interval or intervals (if any) which are to lapse
between installments, and

(iv) the effect which death, Permanent Disability or other
event designated by the Plan Administrator is to have upon the vesting
schedule, shall be determined by the Plan Administrator and incorporated
into the Stock Issuance Agreement.

2. Any new, substituted or additional securities or other property
(including money paid other than as a regular cash dividend) which the
Participant may have the right to receive with respect to the Participant's
unvested shares of Common Stock by reason of any stock dividend, stock split,
recapitalization, combination of shares, exchange of shares or other change
affecting the outstanding Common Stock as a class without the Corporation's
receipt of consideration shall be issued subject to (i) the same vesting
requirements applicable to the Participant's unvested shares of Common Stock and
(ii) such escrow arrangements as the Plan Administrator shall deem appropriate.

3. The Participant shall have full stockholder rights with respect to
any shares of Common Stock issued to the Participant under the Stock Issuance
Program, whether or not the Participant's interest in those shares is vested.
Accordingly, the Participant shall have the right to vote such shares and to
receive any regular cash dividends paid on such shares.

4. Should the Participant cease to remain in Service while holding one
or more unvested shares of Common Stock issued under the Stock Issuance Program
or should the performance objectives not be attained with respect to one or more
such unvested shares of Common Stock, then those shares shall be immediately
surrendered to the Corporation for cancellation, and the Participant shall have
no further stockholder rights with respect to those shares. To the extent the
surrendered shares were previously issued to the Participant for consideration
paid in cash or cash equivalent (including the

<PAGE> 16

Participant's purchase-money indebtedness), the Corporation shall repay to the
Participant the cash consideration paid for the surrendered shares and shall
cancel the unpaid principal balance of any outstanding purchase-money note of
the Participant attributable to the surrendered shares.

5. The Plan Administrator may in its discretion waive the surrender
and cancellation of one or more unvested shares of Common Stock which would
otherwise occur upon the cessation of the Participant's Service or the non-
attainment of the performance objectives applicable to those shares. Such waiver
shall result in the immediate vesting of the Participant's interest in the
shares as to which the waiver applies. Such waiver may be effected at any time,
whether before or after the Participant's cessation of Service or the attainment
or non-attainment of the applicable performance objectives.

II. CORPORATE TRANSACTION/CHANGE IN CONTROL

A. All of the Corporation's outstanding repurchase/cancellation rights
under the Stock Issuance Program shall terminate automatically, and all the
shares of Common Stock subject to those terminated rights shall immediately vest
in full, in the event of any Corporate Transaction, except to the extent (i)
those repurchase/cancellation rights are to be assigned to the successor
corporation (or parent thereof) in connection with such Corporate Transaction or
(ii) such accelerated vesting is precluded by other limitations imposed in the
Stock Issuance Agreement.

B. The Plan Administrator shall have the discretionary authority,
exercisable either at the time the unvested shares are issued or any time while
the Corporation's repurchase/cancellation rights remain outstanding under the
Stock Issuance Program, to provide that those rights shall automatically
terminate in whole or in part, and the shares of Common Stock subject to those
terminated rights shall immediately vest, in the event the Participant's Service
should subsequently terminate by reason of an Involuntary Termination within a
designated period (not to exceed eighteen (18) months) following the effective
date of any Corporate Transaction in which those repurchase/cancellation rights
are assigned to the successor corporation (or parent thereof).

C. The Plan Administrator shall have the discretionary authority,
exercisable either at the time the unvested shares are issued or any time while
the Corporation's repurchase/cancellation rights remain outstanding under the
Stock Issuance Program, to provide that those rights shall automatically
terminate in whole or in part, and the shares of Common Stock subject to those
terminated rights shall immediately vest, in the event the Participant's Service
should subsequently terminate by reason of an Involuntary Termination within a
designated period (not to exceed eighteen (18) months) following the effective
date of any Change in Control.

III. SHARE ESCROW/LEGENDS

Unvested shares may, in the Plan Administrator's discretion, be held
in escrow by

<PAGE> 17

the Corporation until the Participant's interest in such shares vests or may be
issued directly to the Participant with restrictive legends on the certificates
evidencing those unvested shares.

ARTICLE FIVE

AUTOMATIC OPTION GRANT PROGRAM

I. OPTION TERMS

A. GRANT DATES. On the date of each Annual Stockholders Meeting held
after 1997, option grants shall be made to each Eligible Director who is a
member of the Board immediately after that particular Annual Meeting. Each
automatic option grant shall be a Non-Statutory Option. The number of shares of
Common Stock subject to the option shall be equal to 1,500 shares. There shall
be no limit on the number of such automatic option grants any one Eligible
Director may receive over his or her period of Board service, and non-employee
Board members who have previously been in the employ of the Corporation (or any
Parent or Subsidiary) or who have otherwise received a stock option grant from
the Corporation prior to the Effective Date shall be eligible to receive one or
more such annual option grants over their period of continued Board service.

B. EXERCISE PRICE.

1. The exercise price per share shall be equal to one hundred
percent (100%) of the Fair Market Value per share of Common Stock on the option
grant date.

2. The exercise price shall be payable in one or more of the
alternative forms authorized under the Discretionary Option Grant Program.
Except to the extent the sale and remittance procedure specified thereunder is
utilized, payment of the exercise price for the purchased shares must be made on
the Exercise Date.

C. OPTION TERM. Each option shall have a term of ten (10) years
measured from the option grant date.

D. EXERCISE AND VESTING OF OPTIONS. Each option shall be only with
respect to option shares with respect to which the automatic option grant has
become vested. Provided that the non-employee director continues to be a Member
of the Board, each automatic option grant shall vest in twelve equal monthly
installments commencing with the date which is one month after the date of the
Annual Meeting to which the option grant relates. No portion of the automatic
option grant shall vest after the optionee has ceased to be a member of the
Board.

E. TERMINATION OF BOARD SERVICE. The following provisions shall govern
the exercise of any options held by the Optionee at the time the Optionee ceases
to serve as a Board member:

<PAGE> 18

(i) The Optionee (or, in the event of Optionee's death, the
personal representative of the Optionee's estate or the person or persons
to whom the option is transferred pursuant to the Optionee's will or in
accordance with the laws of descent and distribution) shall have a twelve
(12)-month period following the date of such cessation of Board service in
which to exercise each such option.

(ii) During the twelve (12)-month exercise period, the
option may not be exercised in the aggregate for more than the number of
vested shares of Common Stock for which the option is exercisable at the
time of the Optionee's cessation of Board service.

(iii) Should the Optionee cease to serve as a Board member
by reason of death or Permanent Disability, then all shares at the time
subject to the option shall immediately vest so that such option may,
during the twelve (12)-month exercise period following such cessation of
Board service, be exercised for all or any portion of those shares as
fully-vested shares of Common Stock.

(iv) In no event shall the option remain exercisable after
the expiration of the option term. Upon the expiration of the twelve (12)-
month exercise period or (if earlier) upon the expiration of the option
term, the option shall terminate and cease to be outstanding for any vested
shares for which the option has not been exercised. However, the option
shall, immediately upon the Optionee's cessation of Board service for any
reason other than death or Permanent Disability, terminate and cease to be
outstanding to the extent the option is not otherwise at that time
exercisable for vested shares.

II. CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-OVER

A. In the event of any Corporate Transaction, the shares of Common
Stock at the time subject to each outstanding option but not otherwise vested
shall automatically vest in full so that each such option shall, immediately
prior to the effective date of the Corporate Transaction, become fully
exercisable for all of the shares of Common Stock at the time subject to such
option and may be exercised for all or any portion of those shares as fully-
vested shares of Common Stock. Immediately following the consummation of the
Corporate Transaction, each automatic option grant shall terminate and cease to
be outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

B. In connection with any Change in Control, the shares of Common
Stock at the time subject to each outstanding option but not otherwise vested
shall automatically vest in full so that each such option shall, immediately
prior to the effective date of the

<PAGE> 19

Change in Control, become fully exercisable for all of the shares of Common
Stock at the time subject to such option and may be exercised for all or any
portion of those shares as fully-vested shares of Common Stock. Each such option
shall remain exercisable for such fully-vested option shares until the
expiration or sooner termination of the option term or the surrender of the
option in connection with a Hostile Take-Over.

C. Upon the occurrence of a Hostile Take-Over, the Optionee shall have
a thirty (30)-day period in which to surrender to the Corporation each of his or
her outstanding automatic option grants. The Optionee shall in return be
entitled to a cash distribution from the Corporation in an amount equal to the
excess of (i) the Take-Over Price of the shares of Common Stock at the time
subject to each surrendered option (whether or not the Optionee is otherwise at
the time vested in those shares) over (ii) the aggregate exercise price payable
for such shares. Such cash distribution shall be paid within five (5) days
following the surrender of the option to the Corporation. No approval or consent
of the Board or any Plan Administrator shall be required in connection with such
option surrender and cash distribution.

E. The grant of options under the Automatic Option Grant Program shall
in no way affect the right of the Corporation to adjust, reclassify, reorganize
or otherwise change its capital or business structure or to merge, consolidate,
dissolve, liquidate or sell or transfer all or any part of its business or
assets.

III. REMAINING TERMS

The remaining terms of each option granted under the Automatic Option
Grant Program shall be the same as the terms in effect for option grants made
under the Discretionary Option Grant Program.

ARTICLE SIX

MISCELLANEOUS

I. FINANCING

The Plan Administrator may permit any Optionee or Participant to pay
the option exercise price under the Discretionary Option Grant Program or the
purchase price of

<PAGE> 20

shares issued under the Stock Issuance Program by delivering a full-recourse,
interest bearing promissory note payable in one or more installments. The terms
of any such promissory note (including the interest rate and the terms of
repayment) shall be established by the Plan Administrator in its sole
discretion. In no event may the maximum credit available to the Optionee or
Participant exceed the sum of (i) the aggregate option exercise price or
purchase price payable for the purchased shares plus (ii) any Federal, state and
local income and employment tax liability incurred by the Optionee or the
Participant in connection with the option exercise or share purchase.

II. TAX WITHHOLDING

A. The Corporation's obligation to deliver shares of Common Stock upon
the exercise of options or the issuance or vesting of such shares under the Plan
shall be subject to the satisfaction of all applicable Federal, state and local
income and employment tax withholding requirements.

B. The Plan Administrator may, in its discretion, provide any or all
holders of Non-Statutory Options or unvested shares of Common Stock under the
Plan (other than the options granted or the shares issued under the Automatic
Option Grant Program) with the right to use shares of Common Stock in
satisfaction of all or part of the Taxes incurred by such holders in connection
with the exercise of their options or the vesting of their shares. Such right
may be provided to any such holder in either or both of the following formats:

Stock Withholding: The election to have the Corporation withhold,
from the shares of Common Stock otherwise issuable upon the exercise of such
Non-Statutory Option or the vesting of such shares, a portion of those shares
with an aggregate Fair Market Value equal to the percentage of the Taxes (not to
exceed one hundred percent (100%)) designated by the holder.

Stock Delivery: The election to deliver to the Corporation, at the
time the Non-Statutory Option is exercised or the shares vest, one or more
shares of Common Stock previously acquired by such holder (other than in
connection with the option exercise or share vesting triggering the Taxes) with
an aggregate Fair Market Value equal to the percentage of the Taxes (not to
exceed one hundred percent (100%)) designated by the holder.

III. EFFECTIVE DATE AND TERM OF THE PLAN

A. The Plan shall become effective immediately upon the Plan Effective
Date. However, the Salary Investment Option Grant Program shall not be
implemented until such time as the Primary Committee may deem appropriate.
Options may be granted under the Discretionary Option Grant or Automatic Option
Grant Program at any time on or after the Plan Effective Date. However, no
options granted under the Plan may be exercised, and no shares shall be issued
under the Plan, until the Plan is approved by the Corporation's stockholders. If
such stockholder approval is not obtained within twelve

<PAGE> 21

(12) months after the Plan Effective Date, then all options previously granted
under this Plan shall terminate and cease to be outstanding, and no further
options shall be granted and no shares shall be issued under the Plan.

B. The Plan shall serve as the successor to the Predecessor Plans, and
no further option grants or direct stock issuances shall be made under the
Predecessor Plans after the Section 12 Registration Date. All options
outstanding under the Predecessor Plans on the Section 12 Registration Date
shall be incorporated into the Plan at that time and shall be treated as
outstanding options under the Plan. However, each outstanding option so
incorporated shall continue to be governed solely by the terms of the documents
evidencing such option, and no provision of the Plan shall be deemed to affect
or otherwise modify the rights or obligations of the holders of such
incorporated options with respect to their acquisition of shares of Common
Stock.

C. One or more provisions of the Plan, including (without limitation)
the option/vesting acceleration provisions of Article Two relating to Corporate
Transactions and Changes in Control, may, in the Plan Administrator's
discretion, be extended to one or more options incorporated from the Predecessor
Plans which do not otherwise contain such provisions.

D. The Plan shall terminate upon the earliest of (i) the tenth
anniversary of the Plan Effective Date, (ii) the date on which all shares
available for issuance under the Plan shall have been issued as fully-vested
shares or (iii) the termination of all outstanding options in connection with a
Corporate Transaction. Upon such plan termination, all outstanding option grants
and unvested stock issuances shall thereafter continue to have force and effect
in accordance with the provisions of the documents evidencing such grants or
issuances.

IV. AMENDMENT OF THE PLAN

A. The Board shall have complete and exclusive power and authority to
amend or modify the Plan in any or all respects. However, no such amendment or
modification shall adversely affect the rights and obligations with respect to
stock options or unvested stock issuances at the time outstanding under the Plan
unless the Optionee or the Participant consents to such amendment or
modification. In addition, certain amendments may require stockholder approval
if so determined by the Board or pursuant to applicable laws or regulations.

B. Options to purchase shares of Common Stock may be granted under the
Discretionary Option Grant and Salary Investment Option Grant Programs and
shares of Common Stock may be issued under the Stock Issuance Program that are
in each instance in excess of the number of shares then available for issuance
under the Plan, provided any excess shares actually issued under those programs
shall be held in escrow until there is obtained any required approval of an
amendment sufficiently increasing the number of shares of Common Stock available
for issuance under the Plan. If such approval is not obtained within twelve (12)
months after the date the first such excess issuances are

<PAGE> 22

made, then (i) any unexercised options granted on the basis of such excess
shares shall terminate and cease to be outstanding and (ii) the Corporation
shall promptly refund to the Optionees and the Participants the exercise or
purchase price paid for any excess shares issued under the Plan and held in
escrow, together with interest (at the applicable Short Term Federal Rate) for
the period the shares were held in escrow, and such shares shall thereupon be
automatically cancelled and cease to be outstanding.

C. On March 25, 1999, the Board amended the Plan to increase the
maximum number of shares of Common Stock authorized for issuance over the term
of the Plan from 2,587,633 shares to 3,337,633 shares. This amendment is subject
to stockholder approval at the 1999 Annual Meeting. Until such stockholder
approval is obtained, any options granted on the basis of the amendment shall
not become exercisable in whole or in part, and those options shall terminate
without ever becoming exercisable for the option shares. All option grants and
direct stock issuances made prior to the amendment shall remain outstanding in
accordance with the terms and conditions of the respective instruments
evidencing those options or issuances, and nothing in this amendment shall be
deemed to modify or in any way affect those outstanding options or issuances.

V. USE OF PROCEEDS

Any cash proceeds received by the Corporation from the sale of shares
of Common Stock under the Plan shall be used for general corporate purposes.

VI. REGULATORY APPROVALS

A. The implementation of the Plan, the granting of any stock option
under the Plan and the issuance of any shares of Common Stock (i) upon the
exercise of any granted option or (ii) under the Stock Issuance Program shall be
subject to the Corporation's procurement of all approvals and permits required
by regulatory authorities having jurisdiction over the Plan, the stock options
granted under it and the shares of Common Stock issued pursuant to it.

B. No shares of Common Stock or other assets shall be issued or
delivered under the Plan unless and until there shall have been compliance with
all applicable requirements of Federal and state securities laws, including the
filing and effectiveness of the Form S-8 registration statement for the shares
of Common Stock issuable under the Plan, and all applicable listing requirements
of any stock exchange (or the Nasdaq National Market, if applicable) on which
Common Stock is then listed for trading.

VII. NO EMPLOYMENT/SERVICE RIGHTS

Nothing in the Plan shall confer upon the Optionee or the Participant
any right to continue in Service for any period of specific duration or
interfere with or otherwise restrict in any way the rights of the Corporation
(or any Parent or Subsidiary employing or retaining such person) or of the
Optionee or the Participant, which rights are hereby expressly reserved by each,
to terminate such person's Service at any time for any reason, with or without
cause.

Exhibit 99.4

CORSAIR COMMUNICATIONS, INC.
1997 EMPLOYEE STOCK PURCHASE PLAN

I. PURPOSE OF THE PLAN

This Employee Stock Purchase Plan is intended to promote the interests
of Corsair Communications, Inc., a Delaware corporation, by providing eligible
employees with the opportunity to acquire a proprietary interest in the
Corporation through participation in a payroll-deduction based employee stock
purchase plan designed to qualify under Section 423 of the Code.

Capitalized terms herein shall have the meanings assigned to such terms
in the attached Appendix.

II. ADMINISTRATION OF THE PLAN

The Plan Administrator shall have full authority to interpret and
construe any provision of the Plan and to adopt such rules and regulations for
administering the Plan as it may deem necessary in order to comply with the
requirements of Code Section 423. Decisions of the Plan Administrator shall be
final and binding on all parties having an interest in the Plan.

III. STOCK SUBJECT TO PLAN

A. The stock purchasable under the Plan shall be shares of authorized
but unissued or reacquired Common Stock, including shares of Common Stock
purchased on the open market. The maximum number of shares of Common Stock which
may be issued over the term of the Plan shall not exceed six hundred sixty-six
thousand six hundred sixty seven (666,667) shares. Such share reserve includes
an increase of 400,000 shares authorized by the Board on March 25, 1999, subject
to stockholder approval at the 1999 Annual Meeting.

B. Should any change be made to the Common Stock by reason of any stock
split, stock dividend, recapitalization, combination of shares, exchange of
shares or other change affecting the outstanding Common Stock as a class without
the Corporation's receipt of consideration, appropriate adjustments shall be
made to (i) the maximum number and class of securities issuable under the Plan,
(ii) the maximum number and class of securities purchasable per Participant on
any one Purchase Date and (iii) the number and class of securities and the price
per share in effect under each outstanding purchase right in order to prevent
the dilution or enlargement of benefits thereunder.

IV. OFFERING PERIODS

<PAGE> 2

A. Shares of Common Stock shall be offered for purchase under the Plan
through a series of successive offering periods until such time as (i) the
maximum number of shares of Common Stock available for issuance under the Plan
shall have been purchased or (ii) the Plan shall have been sooner terminated.

B. The initial offering period shall commence as of the Effective Time
of the Plan and shall continue until July 31, 1999. Thereafter, each successive
offering period shall be of 24 months duration. The next offering period shall
commence on the first business day in August 1999, and subsequent offering
periods shall commence as designated by the Plan Administrator. Notwithstanding
the above, the Plan Administrator may shorten the duration of any offering
period to less than twenty-four (24) months provided that such action is taken
prior to the start date of such offering period.

C. Each offering period shall be comprised of a series of one or more
successive Purchase Intervals. Purchase Intervals shall run from the first
business day in February each year to the last business day in July of the same
year and from the first business day in August each year to the last business
day in January of the following year. Accordingly, the first Purchase Interval
in effect under the initial offering period shall commence at the Effective Time
and terminate on the last business day in January 1998.

D. Should the Fair Market Value per share of Common Stock on any
Purchase Date within an offering period be less than the Fair Market Value per
share of Common Stock on the start date of that offering period, then that
offering period shall automatically terminate immediately after the purchase of
shares of Common Stock on such Purchase Date, and a new offering period shall
commence on the next business day following such Purchase Date. The new offering
period shall have a duration of twenty four (24) months, unless a shorter
duration is established by the Plan Administrator within five (5) business days
following the start date of that offering period.

V. ELIGIBILITY

A. Each individual who is an Eligible Employee on the start date of any
offering period under the Plan may enter that offering period on such start date
or on any subsequent Semi-Annual Entry Date within that offering period,
provided he or she remains an Eligible Employee.

B. Each individual who first becomes an Eligible Employee after the
start date of an offering period may enter that offering period on any
subsequent Semi-Annual Entry Date within that offering period on which he or she
is an Eligible Employee.

C. The date an individual enters an offering period shall be designated
his or her Entry Date for purposes of that offering period.

D. To participate in the Plan for a particular offering period, the
Eligible Employee must complete the enrollment forms prescribed by the Plan
Administrator

<PAGE> 3

(including a stock purchase agreement and a payroll deduction authorization) and
file such forms with the Plan Administrator (or its designate) on or before his
or her scheduled Entry Date.

VI. PAYROLL DEDUCTIONS

A. The payroll deduction authorized by the Participant for purposes of
acquiring shares of Common Stock during an offering period may be any multiple
of one percent (1%) of the Base Salary paid to the Participant during each
Purchase Interval within that offering period, up to a maximum of ten percent
(10%). The deduction rate so authorized shall continue in effect throughout the
offering period, except to the extent such rate is changed in accordance with
the following guidelines:

(i) The Participant may, at any time during the offering period,
reduce his or her rate of payroll deduction to become effective as soon
as possible after filing the appropriate form with the Plan
Administrator. The Participant may not, however, effect more than one
(1) such reduction per Purchase Interval.

(ii) The Participant may, prior to the commencement of any new
Purchase Interval within the offering period, increase the rate of his
or her payroll deduction by filing the appropriate form with the Plan
Administrator. The new rate (which may not exceed the ten percent (10%)
maximum) shall become effective on the start date of the first Purchase
Interval following the filing of such form.

B. Payroll deductions shall begin on the first pay day following the
Participant's Entry Date into the offering period and shall (unless sooner
terminated by the Participant) continue through the pay day ending with or
immediately prior to the last day of that offering period. The amounts so
collected shall be credited to the Participant's book account under the Plan,
but no interest shall be paid on the balance from time to time outstanding in
such account. The amounts collected from the Participant shall not be held in
any segregated account or trust fund and may be commingled with the general
assets of the Corporation and used for general corporate purposes.

C. Payroll deductions shall automatically cease upon the termination of
the Participant's purchase right in accordance with the provisions of the Plan.

D. The Participant's acquisition of Common Stock under the Plan on any
Purchase Date shall neither limit nor require the Participant's acquisition of
Common Stock on any subsequent Purchase Date, whether within the same or a
different offering period.

VII. PURCHASE RIGHTS

A. GRANT OF PURCHASE RIGHT. A Participant shall be granted a separate
purchase right for each offering period in which he or she participates. The

<PAGE> 4

purchase right shall be granted on the Participant's Entry Date into the
offering period and shall provide the Participant with the right to purchase
shares of Common Stock, in a series of successive installments over the
remainder of such offering period, upon the terms set forth below. The
Participant shall execute a stock purchase agreement embodying such terms and
such other provisions (not inconsistent with the Plan) as the Plan Administrator
may deem advisable.

Under no circumstances shall purchase rights be granted under the Plan
to any Eligible Employee if such individual would, immediately after the grant,
own (within the meaning of Code Section 424(d)) or hold outstanding options or
other rights to purchase, stock possessing five percent (5%) or more of the
total combined voting power or value of all classes of stock of the Corporation
or any Corporate Affiliate.

B. EXERCISE OF THE PURCHASE RIGHT. Each purchase right shall be
automatically exercised in installments on each successive Purchase Date within
the offering period, and shares of Common Stock shall accordingly be purchased
on behalf of each Participant (other than Participants whose payroll deductions
have previously been refunded pursuant to the Termination of Purchase Right
provisions below) on each such Purchase Date. The purchase shall be effected by
applying the Participant's payroll deductions for the Purchase Interval ending
on such Purchase Date to the purchase of whole shares of Common Stock at the
purchase price in effect for the Participant for that Purchase Date.

C. PURCHASE PRICE. The purchase price per share at which Common Stock
will be purchased on the Participant's behalf on each Purchase Date within the
offering period shall not be less than eighty-five percent (85%) of the lower of
(i) the Fair Market Value per share of Common Stock on the Participant's Entry
Date into that offering period or (ii) the Fair Market Value per share of Common
Stock on that Purchase Date.

D. NUMBER OF PURCHASABLE SHARES. The number of shares of Common Stock
purchasable by a Participant on each Purchase Date during the offering period
shall be the number of whole shares obtained by dividing the amount collected
from the Participant through payroll deductions during the Purchase Interval
ending with that Purchase Date by the purchase price in effect for the
Participant for that Purchase Date but in no event may any Participant purchase
more than 7,500 shares on any Purchase Date.

E. EXCESS PAYROLL DEDUCTIONS. Any payroll deductions not applied to the
purchase of shares of Common Stock on any Purchase Date because they are not
sufficient to purchase a whole share of Common Stock shall be held for the
purchase of Common Stock on the next Purchase Date. However, any payroll
deductions not applied to the purchase of Common Stock by reason of the
limitation on the maximum number of shares purchasable by the Participant on the
Purchase Date shall be promptly refunded.

F. TERMINATION OF PURCHASE RIGHT. The following provisions shall govern
the termination of outstanding purchase rights:

(i) A Participant may, at any time prior to the next
scheduled Purchase Date in the offering period, terminate his or her
outstanding purchase right by filing the appropriate form with the Plan
Administrator (or its designate), and no further payroll deductions
shall be collected from the Participant with respect to the terminated
purchase right. Any payroll deductions collected during the Purchase
Interval in which such termination occurs shall, at the Participant's
election, be immediately refunded or held for the purchase of shares on
the next Purchase Date. If no such election is made at the time such
purchase right is terminated, then the payroll deductions collected with
respect to the terminated right shall be refunded as soon as possible.

(ii) The termination of such purchase right shall be
irrevocable, and the Participant may not subsequently rejoin the
offering period for which the terminated purchase right was granted. In
order to resume participation in any subsequent offering period, such
individual must re-enroll in the Plan (by making a timely filing of the
prescribed enrollment forms) on or before his or her scheduled Entry
Date into that offering period.

(iii) Should the Participant cease to remain an Eligible
Employee for any reason (including death, disability or change in
status) while his or her purchase right remains outstanding, then that
purchase right shall immediately terminate, and all of the Participant's
payroll deductions for the Purchase Interval in which the purchase right
so terminates shall be immediately refunded. However, should the
Participant cease to remain in active service by reason of an approved
unpaid leave of absence, then the Participant shall have the right,
exercisable up until the last business day of the Purchase Interval in
which such leave commences, to (a) withdraw all the payroll deductions
collected to date on his or her behalf for that Purchase Interval or (b)
have such funds held for the purchase of shares on his or her behalf on
the next scheduled Purchase Date. In no event, however, shall any
further payroll deductions be collected on the Participant's behalf
during such leave. Upon the Participant's return to active service, his
or her payroll deductions under the Plan shall automatically resume at
the rate in effect at the time the leave began, unless the Participant
withdraws from the Plan prior to his or her return.

G. CORPORATE TRANSACTION. Each outstanding purchase right shall
automatically be exercised, immediately prior to the effective date of any
Corporate Transaction, by applying the payroll deductions of each Participant
for the Purchase Interval in which such Corporate Transaction occurs to the
purchase of whole shares of Common Stock at a purchase price per share not less
than eighty-five percent (85%) of the lower of (i) the Fair Market Value per
share of Common Stock on the Participant's Entry Date into the offering period
in which such Corporate Transaction occurs or (ii) the Fair Market Value per
share of Common Stock immediately prior to the effective date of

5
<PAGE> 6

such Corporate Transaction. However, the applicable limitation on the number of
shares of Common Stock purchasable per Participant shall continue to apply to
any such purchase.

The Corporation shall use its best efforts to provide at least ten
(10)-days prior written notice of the occurrence of any Corporate Transaction,
and Participants shall, following the receipt of such notice, have the right to
terminate their outstanding purchase rights prior to the effective date of the
Corporate Transaction.

H. PRORATION OF PURCHASE RIGHTS. Should the total number of shares of
Common Stock to be purchased pursuant to outstanding purchase rights on any
particular date exceed the number of shares then available for issuance under
the Plan, the Plan Administrator shall make a pro-rata allocation of the
available shares on a uniform and nondiscriminatory basis, and the payroll
deductions of each Participant, to the extent in excess of the aggregate
purchase price payable for the Common Stock pro-rated to such individual, shall
be refunded.

I. ASSIGNABILITY. The purchase right shall be exercisable only by the
Participant and shall not be assignable or transferable by the Participant.

J. STOCKHOLDER RIGHTS. A Participant shall have no stockholder rights
with respect to the shares subject to his or her outstanding purchase right
until the shares are purchased on the Participant's behalf in accordance with
the provisions of the Plan and the Participant has become a holder of record of
the purchased shares.

VIII. ACCRUAL LIMITATIONS

A. No Participant shall be entitled to accrue rights to acquire Common
Stock pursuant to any purchase right outstanding under this Plan if and to the
extent such accrual, when aggregated with (i) rights to purchase Common Stock
accrued under any other purchase right granted under this Plan and (ii) similar
rights accrued under other employee stock purchase plans (within the meaning of
Code Section 423) of the Corporation or any Corporate Affiliate, would otherwise
permit such Participant to purchase more than Twenty-Five Thousand Dollars
($25,000) worth of stock of the Corporation or any Corporate Affiliate
(determined on the basis of the Fair Market Value per share on the date or dates
such rights are granted) for each calendar year such rights are at any time
outstanding.

B. For purposes of applying such accrual limitations to the purchase
rights granted under the Plan, the following provisions shall be in effect:

(i) The right to acquire Common Stock under each outstanding
purchase right shall accrue in a series of installments on each
successive Purchase Date during the offering period on which such right
remains outstanding.

6
<PAGE> 7

(ii) No right to acquire Common Stock under any outstanding
purchase right shall accrue to the extent the Participant has already
accrued in the same calendar year the right to acquire Common Stock
under one (1) or more other purchase rights at a rate equal to
Twenty-Five Thousand Dollars ($25,000) worth of Common Stock (determined
on the basis of the Fair Market Value per share on the date or dates of
grant) for each calendar year such rights were at any time outstanding.

C. If by reason of such accrual limitations, any purchase right of a
Participant does not accrue for a particular Purchase Interval, then the payroll
deductions which the Participant made during that Purchase Interval with respect
to such purchase right shall be promptly refunded.

D. In the event there is any conflict between the provisions of this
Article and one or more provisions of the Plan or any instrument issued
thereunder, the provisions of this Article shall be controlling.

IX. EFFECTIVE TIME AND TERM OF THE PLAN

A. The Plan shall become effective at the Effective Time, provided no
purchase rights granted under the Plan shall be exercised, and no shares of
Common Stock shall be issued hereunder, until (i) the Plan shall have been
approved by the stockholders of the Corporation and (ii) the Corporation shall
have complied with all applicable requirements of the 1933 Act (including the
registration of the shares of Common Stock issuable under the Plan on a Form S-8
registration statement filed with the Securities and Exchange Commission), all
applicable listing requirements of any stock exchange (or the Nasdaq National
Market, if applicable) on which the Common Stock is listed for trading and all
other applicable requirements established by law or regulation. In the event
such stockholder approval is not obtained, or such compliance is not effected,
within twelve (12) months after the date on which the Plan is adopted by the
Board, the Plan shall terminate and have no further force or effect, and all
sums collected from Participants during the initial offering period hereunder
shall be refunded.

B. Unless sooner terminated by the Board, the Plan shall terminate upon
the earliest of (i) the last business day in July 2007, (ii) the date on which
all shares available for issuance under the Plan shall have been sold pursuant
to purchase rights exercised under the Plan or (iii) the date on which all
purchase rights are exercised in connection with a Corporate Transaction. No
further purchase rights shall be granted or exercised, and no further payroll
deductions shall be collected, under the Plan following such termination.

X. AMENDMENT OF THE PLAN

The Board may alter, amend, suspend or discontinue the Plan at any time
to become effective immediately following the close of any Purchase Interval.
However, the Board may not, without the approval of the Corporation's
stockholders, (i) materially

7
<PAGE> 8

increase the number of shares of Common Stock issuable under the Plan or the
maximum number of shares purchasable per Participant on any one Purchase Date,
except for permissible adjustments in the event of certain changes in the
Corporation's capitalization, (ii) alter the purchase price formula so as to
reduce the purchase price payable for the shares of Common Stock purchasable
under the Plan or (iii) materially increase the benefits accruing to
Participants under the Plan or materially modify the requirements for
eligibility to participate in the Plan.

On March 25, 1999, the Board amended the Plan to increase the maximum
number of shares of Common Stock authorized for issuance over the term of the
Plan from 266,667 shares to 666,667 shares. This amendment is subject to
stockholder approval at the 1999 Annual Meeting.

XI. GENERAL PROVISIONS

A. All costs and expenses incurred in the administration of the Plan
shall be paid by the Corporation.

B. Nothing in the Plan shall confer upon the Participant any right to
continue in the employ of the Corporation or any Corporate Affiliate for any
period of specific duration or interfere with or otherwise restrict in any way
the rights of the Corporation (or any Corporate Affiliate employing such person)
or of the Participant, which rights are hereby expressly reserved by each, to
terminate such person's employment at any time for any reason, with or without
cause.

C. The provisions of the Plan shall be governed by the laws of the State
of Delaware without resort to that State's conflict-of-laws rules.
