REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS (FEBRUARY 26, 2001)

         The Audit Committee of the Board of Directors (the "Committee") is
composed of three independent directors and operates under a written charter
adopted by the Board of Directors, a copy of which is attached hereto as
Appendix A. The members of the Committee are Dr. Jaffe, Dr. Carter and Mr.
Edwards. The Committee recommends to the Board of Directors, subject to
stockholder ratification, the selection of the Company's independent
accountants.

         Management is responsible for the Company's internal controls and the
financial reporting process. The independent accountants are responsible for
performing an independent audit of the Company's financial statements in
accordance with auditing standards generally accepted in the United States of
America and to issue a report thereon. The Committee's responsibility is to
monitor and oversee these processes.

         In this context, the Committee has met and held discussions with
management and the independent accountants. Management represented to the
Committee that the Company's financial statements were prepared in accordance
with accounting principles generally accepted in the United States of America,
and the Committee has reviewed and discussed the financial statements with
management and the independent accountants. The Committee discussed with the
independent accountants the matters required to be discussed by Statement on
Auditing Standards No. 61 (Communication with Audit Committees).

         The Company's independent accountants also provided to the Committee
the written disclosures and letter required by Independence Standards Board
Standard No. 1 (Independence Discussions with Audit Committees), and the
Committee discussed with the independent accountants that firm's independence.

         Based on the Committee's discussion with management and the independent
accountants and the Committee's review of the representation of management and
the report of the independent accountants to the Committee, the Committee
recommended that the Board of Directors include the audited financial statements
in the Company's Annual Report on Form 10-K for the year ended December 31, 2000
filed with the Securities and Exchange Commission.

         Dr. Marvin Jaffe
         Dr. Stephen Carter

                                   PROPOSAL 2

                  APPROVAL OF 2001 EMPLOYEE STOCK PURCHASE PLAN


         In February 2001, the Board adopted the Company's 2001 Employee Stock
Purchase Plan ("Purchase Plan"), subject to stockholder approval. There are
2,500,000 shares of Common Stock reserved for issuance under the Purchase Plan,
none of which have been granted as of March 7, 2001.

         Stockholders are requested in this Proposal 2 to approve the Purchase
Plan. The affirmative vote of the holders of a majority of the shares present in
person or represented by proxy and entitled to vote at the meeting will be
required to approve the Purchase Plan. Abstentions will be counted toward the
tabulation of votes cast on proposals presented to the stockholders and will
have the same effect as negative votes. Broker non-votes are counted towards a
quorum, but are not counted for any purpose in determining whether this matter
has been approved.

                        THE BOARD OF DIRECTORS RECOMMENDS
                         A VOTE IN FAVOR OF PROPOSAL 2.

         The essential features of the Purchase Plan are outlined below:

PURPOSE

         The purpose of the Purchase Plan is to provide a means by which
employees of the Company (and any parent or subsidiary of the Company designated
by the Board to participate in the Purchase Plan) may be given an opportunity to
purchase Common Stock of the Company through payroll deductions, to assist the
Company in retaining the services of its employees, to secure and retain the
services of new employees, and to provide incentives for such persons to exert
maximum efforts for the success of the Company. All of the Company's
approximately 50 employees are eligible to participate in the Purchase Plan.

         The rights to purchase Common Stock granted under the Purchase Plan are
intended to qualify as options issued under an "employee stock purchase plan" as
that term is defined in Section 423(b) of the Internal Revenue Code of 1986, as
amended (the "Code").

ADMINISTRATION

         The Board administers the Purchase Plan and has the final power to
construe and interpret both the Purchase Plan and the rights granted under it.
The Board has the power, subject to the provisions of the Purchase Plan, to
determine when and how rights to purchase Common Stock of the Company will be
granted, the provisions of each offering of such rights (which need not be
identical), and whether employees of any parent or subsidiary of the Company
will be eligible to participate in the Purchase Plan.

         The Board has the power to delegate administration of the Purchase Plan
to a committee composed of one or more members of the Board. The Board has
delegated administration of the Purchase Plan to the Compensation Committee of
the Board. As used herein with respect to the Purchase Plan, the "Board" refers
to the Compensation Committee and to the Board.

OFFERINGS

         The Purchase Plan is implemented by offerings of rights to all eligible
employees from time to time by the Board. Generally, each offering is 24 months
long and is divided into four shorter "purchase


                                       7
   10

periods" approximately six months long. The Purchase Plan provides for each
offering to restart if the fair market value of the Company's Common Stock is
less on the first day of a new purchase period than it was on the commencement
date of the offering.

ELIGIBILITY

         Any person who is employed by the Company on the first day of an
offering is eligible to participate in that offering. Unless the Board provides
otherwise in an offering, officers of the Company who are "highly compensated"
as defined in the Code are eligible to participate in the offerings.

         However, no employee is eligible to participate in the Purchase Plan
if, immediately after the grant of purchase rights, the employee would own,
directly or indirectly, stock possessing 5% or more of the total combined voting
power or value of all classes of stock of the Company or of any parent or
subsidiary of the Company (including any stock which such employee may purchase
under all outstanding rights and options). In addition, no employee may purchase
more than $25,000 worth of Common Stock (determined at the fair market value of
the shares at the time such rights are granted) under all employee stock
purchase plans of the Company and its affiliates in any calendar year.

PARTICIPATION IN THE PLAN

         Eligible employees enroll in the Purchase Plan by delivering to the
Company, prior to the date selected by the Board as the offering date for the
offering, an agreement authorizing payroll deductions of up to 10% of such
employees' base compensation during the offering.

PURCHASE PRICE

         The purchase price per share at which shares of Common Stock are sold
in an offering under the Purchase Plan is the lower of (i) 85% of the fair
market value of a share of Common Stock on first day of the offering or (ii) 85%
of the fair market value of a share of Common Stock on the last day of the
purchase period.

PAYMENT OF PURCHASE PRICE; PAYROLL DEDUCTIONS

         The purchase price of the shares is accumulated by payroll deductions
over the offering. At any time during the offering, a participant may reduce or
terminate his or her payroll deductions as the Board provides in the offering. A
participant may not increase or begin such payroll deductions after the
beginning of any purchase period. All payroll deductions made for a participant
are credited to his or her account under the Purchase Plan and deposited with
the general funds of the Company. A participant may not make additional payments
into such account.

PURCHASE OF STOCK

         By executing an agreement to participate in the Purchase Plan, the
employee is entitled to purchase shares under the Purchase Plan. In connection
with offerings made under the Purchase Plan, the Board specifies a maximum
number of shares of Common Stock an employee may be granted the right to
purchase and the maximum aggregate number of shares of Common Stock that may be
purchased pursuant to such offering by all participants. If the aggregate number
of shares to be purchased upon exercise of rights granted in the offering would
exceed the maximum aggregate number of shares of Common Stock available, the
Board would make a pro rata allocation of available shares in a uniform and
equitable manner. Unless the employee's participation is discontinued, his or
her right to purchase shares is exercised automatically at the end of the
purchase period at the applicable price. See "Withdrawal" below.


                                       8
   11


WITHDRAWAL

         While each participant in the Purchase Plan is required to sign an
agreement authorizing payroll deductions, the participant may withdraw from a
given offering by terminating his or her payroll deductions and by delivering to
the Company a notice of withdrawal from the Purchase Plan. Such withdrawal may
be elected at any time up to 10 days prior to the end of the applicable purchase
period.

         Upon any withdrawal from an offering by the employee, the Company will
distribute to the employee his or her accumulated payroll deductions without
interest, less any accumulated deductions previously applied to the purchase of
shares of Common Stock on the employee's behalf during such offering, and such
employee's interest in the offering will be automatically terminated. The
employee is not entitled to again participate in that offering. However, an
employee's withdrawal from an offering will not have any effect upon such
employee's eligibility to participate in subsequent offerings under the Purchase
Plan.

TERMINATION OF EMPLOYMENT

         Rights granted pursuant to any offering under the Purchase Plan
terminate immediately upon cessation of an employee's employment for any reason,
and the Company will distribute to such employee all of his or her accumulated
payroll deductions, without interest.

RESTRICTIONS ON TRANSFER

         Rights granted under the Purchase Plan are not transferable and may be
exercised only by the person to whom such rights are granted.

DURATION, AMENDMENT AND TERMINATION

         The Board may suspend or terminate the Purchase Plan at any time.
Unless terminated earlier, the Purchase Plan will terminate on February 27,
2011.

         The Board may amend the Purchase Plan at any time. No amendment will be
effective unless approved by the stockholders to the extent such approval is
necessary for the Purchase Plan to satisfy the requirements of Section 423 of
the Code, any Nasdaq or other securities listing requirements or other
applicable laws or regulations. Currently, the Code requires stockholder
approval within 12 months before or after the adoption of an amendment (i) to
increase the amount of shares of Common Stock reserved for issuance pursuant to
the Purchase Plan or (ii) to make certain modifications to the provisions that
relate to eligibility for participation in the Purchase Plan. Stockholder
approval is not required for amendments relating to adjustments upon changes in
securities (as described in Section 14 of the Purchase Plan) or amendments
solely to benefit the administration of the Purchase Plan, to take into account
a change in legislation or to obtain or maintain favorable tax, exchange control
or regulatory treatment.

         Rights granted before amendment or termination of the Purchase Plan
will not be altered or impaired by any amendment or termination of the Purchase
Plan without consent of the employee to whom such rights were granted.

EFFECT OF CERTAIN CORPORATE EVENTS

         In the event of a dissolution, liquidation or specified type of merger
of the Company, the surviving corporation either will assume the rights under
the Purchase Plan or substitute similar rights, or the exercise date of any
ongoing offering will be accelerated such that the outstanding rights may be
exercised immediately prior to any such event.

STOCK SUBJECT TO PURCHASE PLAN

         1,500,000 shares of Common Stock are initially reserved for issuance
under the Purchase Plan. On the first day of each calendar year, commencing on
January 1, 2002 and ending (and including) January 1, 2011, the share reserve
will increase automatically by the lesser of (a) 2% of the number of shares of
Common Stock outstanding on each January 1 (rounded to the nearest whole share
and calculated on a fully diluted basis) or (b) 440,000 shares of Common Stock.
However, the Board may provide for a lesser increase each year. Notwithstanding
the foregoing, the share reserve in the aggregate shall not exceed 2,500,000
shares. If rights granted under the Purchase Plan expire, lapse or otherwise
terminate without being exercised, the shares of Common Stock not purchased
under such rights again become available for issuance under the Purchase Plan.

FEDERAL INCOME TAX INFORMATION

         Rights granted under the Purchase Plan are intended to qualify for
favorable federal income tax treatment associated with rights granted under an
employee stock purchase plan which qualifies under provisions of Section 423 of
the Code.

         A participant will be taxed on amounts withheld for the purchase of
shares of Common Stock as if such amounts were actually received. Other than
this, no income will be taxable to a participant until disposition of the
acquired shares, and the method of taxation will depend upon the holding period
of the acquired shares.

         If the stock is disposed of at least two years after the beginning of
the offering period and at least one year after the stock is transferred to the
participant, then the lesser of (i) the excess of the fair market value of the
stock at the time of such disposition over the exercise price or (ii) the excess
of the fair market value of the stock as of the beginning of the offering period
over the exercise price (determined as of the beginning of the offering period)
will be treated as ordinary income. Any further gain or any loss will be taxed
as a long-term capital gain or loss. Such capital gains currently are generally
subject to lower tax rates than ordinary income.

         If the stock is sold or disposed of before the expiration of either of
the holding periods described above, then the excess of the fair market value of
the stock on the exercise date over the exercise price will be treated as
ordinary income at the time of such disposition. The balance of any gain will be
treated as capital gain. Even if the stock is later disposed of for less than
its fair market value on the exercise date, the same amount of ordinary income
is attributed to the participant, and a capital loss is recognized equal to the
difference between the sales price and the fair market value of the stock on
such exercise date. Any capital gain or loss will be short-term or long-term,
depending on how long the stock has been held.

         There are no federal income tax consequences to the Company by reason
of the grant or exercise of rights under the Purchase Plan. The Company is
entitled to a deduction to the extent amounts are taxed as ordinary income to a
participant (subject to the requirement of reasonableness and the satisfaction
of tax reporting obligations).

                                   PROPOSAL 3

                RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS


         The Board of Directors has selected PricewaterhouseCoopers LLP as the
Company's independent auditors for the fiscal year ending December 31, 2001 and
has further directed that management submit the selection of independent
auditors for ratification by the stockholders at the Annual Meeting.
PricewaterhouseCoopers LLP has audited the Company's financial statements since
its inception in September 1992. Representatives of PricewaterhouseCoopers LLP
are expected to be present at the Annual Meeting, will have an opportunity to
make a statement if they so desire and will be available to respond to
appropriate questions.

         Stockholder ratification of the selection of PricewaterhouseCoopers LLP
as the Company's independent auditors is not required by the Company's Bylaws or
otherwise. However, the Board is submitting the selection of
PricewaterhouseCoopers LLP to the stockholders for ratification as a matter of
good corporate practice. If the stockholders fail to ratify the selection, the
Audit Committee and the Board will reconsider whether or not to retain that
firm. Even if the selection is ratified, the Audit Committee and the Board in
their discretion may direct the appointment of different independent auditors at
any time during the year if they determine that such a change would be in the
best interests of the Company and its stockholders.

         The affirmative vote of the holders of a majority of the shares present
in person or represented by proxy and entitled to vote at the Annual Meeting
will be required to ratify the selection of PricewaterhouseCoopers LLP.
Abstentions will be counted toward the tabulation of votes cast on proposals
presented to the stockholders and will have the same effect as negative votes.
Broker non-votes are counted towards a quorum, but are not counted for any
purpose in determining whether this matter has been approved.

         AUDIT FEES. During the fiscal year ended December 31, 2000, the
aggregate fees billed by PricewaterhouseCoopers LLP for the audit of the
Company's financial statements for such fiscal year and for the reviews of the
Company's interim financial statements was $50,000.

         ALL OTHER FEES. During fiscal year ended December 31, 2000, the
aggregate fees billed by PricewaterhouseCoopers LLP for professional services
other than audit fees was $190,582.

         The Audit Committee has determined the rendering of the non-audit
services by PricewaterhouseCoopers LLP is compatible with maintaining the
auditor's independence.



                        THE BOARD OF DIRECTORS RECOMMENDS
                         A VOTE IN FAVOR OF PROPOSAL 3.

                             EXECUTIVE COMPENSATION

COMPENSATION OF DIRECTORS

         We do not provide cash compensation to members of our Board of
Directors for serving on our Board of Directors and for attendance at committee
meetings. Members of our Board of Directors are reimbursed for some expenses
incurred in connection with attendance at Board and committee meetings in
accordance with Company policy.

         Each of our non-employee directors receives stock option grants under a
stock option grant program for non-employee directors (the "Directors' Program")
under our 2000 Stock Incentive Compensation Plan (the "Plan"). Under this
program, each person who becomes a non-employee director is automatically
granted a nonqualified stock option to purchase 10,000 shares of Common Stock on
the date of his or her election. One-third of this option vests on each of the
first, second and third anniversaries of the grant date. On the date of each
annual meeting of stockholders of the Company, each non-employee director who
continues to serve on the Board of Directors is granted an option to purchase
10,000 shares of Common Stock upon reelection or reappointment to the Board of
Directors, which fully vests on the first anniversary of the date of grant,
assuming continued service as a director during the year after the grant date.
The exercise price of all options granted under the program is equal to the fair
market value of the Common Stock on the grant date. As of February 23, 2001, no
options had been granted under the Directors' Program.

                              EMPLOYMENT AGREEMENTS

         In January 2001, the Company entered into employment agreements with
each of Drs. Hoffman and Gerber and Mr. Hart. The employment agreements provide
for annual base salaries for Drs. Hoffman and Gerber and Mr. Hart of $225,000,
$247,517 and $218,402, respectively, which amounts may be adjusted periodically
in the sole discretion of the Board of Directors. In addition, Drs. Hoffman and
Gerber and Mr. Hart are eligible for discretionary bonuses in amounts equal to
35%, 30% and 30% of their respective base salaries. The decision to award the
bonuses or modify the amount of the bonuses is within the sole discretion of the
Board of Directors.

         Each of these employment agreements provides that the executive's
employment with the Company is at-will and may be altered or terminated by
either the executive or the Company at any time. However, if the Company
terminates the executive's employment without just cause or if the executive
resigns for good reason, other than pursuant to a change in control, the
executive will be entitled to receive: (a) his base salary for six months
following the date of termination, (b) payment of any accrued but unused
vacation and sick leave, (c) payment of premiums of the executive's supplemental
disability plan for 24 months following the date of termination, and (d) payment
of premiums for the executive's group health insurance COBRA continuation
coverage for up to six months after the date of termination.

         Each of these employment agreements also provides that if the Company
terminates the executive's employment without just cause or if the executive
resigns for good reason, within one month prior to or 13 months following the
effective date of a change in control, the executive will be entitled to
receive: (a) his base salary for two years following the date of termination,
(b) payment of any accrued but unused vacation and sick leave, (c) reimbursement
for premiums of the executive's supplemental disability plan for 24 months
following the date of termination, (d) a bonus in an amount equal to the bonus
paid in the year immediately preceding the change in control, and (e) payment of
premiums for the executive's group health insurance COBRA continuation coverage
for up to 18 months after the date of termination. In addition, the vesting of
any outstanding stock options issued to the executive shall be accelerated in
full, and the time during which such options may be exercised will be extended
to 24 months following the date of such change in control.

         REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS
                            ON EXECUTIVE COMPENSATION

         The Compensation Committee of the Board of Directors (the "Committee")
is composed of Dr. Jaffe and Mr. Edwards, neither of whom are currently officers
or employees of the Company. The Committee is responsible for establishing the
Company's compensation programs for all employees, including executives. For
executive officers, the Committee evaluates performance and determines
compensation policies and levels.

COMPENSATION PHILOSOPHY

         The goals of the compensation program are to align compensation with
business objectives and performance and to enable the Company to attract, retain
and reward executive officers and other key employees who contribute to the
long-term success of the Company and to motivate them to enhance long-term
stockholder value. Key elements of this philosophy are:

         o        The Company pays competitively with leading biotechnology
                  companies with which the Company competes for talent. To
                  ensure that pay is competitive, the Company regularly compares
                  its pay practices with these companies and sets it pay
                  parameters based on this review.

         o        The Company maintains annual incentive opportunities
                  sufficient to provide motivation to achieve specific
                  operational goals and to generate rewards that bring total
                  compensation to competitive levels.

         o        The Company provides significant equity-based incentives for
                  executive officers and other key employees to ensure that they
                  are motivated over the long-term to respond to the Company's
                  business challenges and opportunities as owners and not just
                  as employees.


2000 EXECUTIVE COMPENSATION

         Base Compensation. Base salaries for executive officers are determined
in part by the Committee in reliance on several pharmaceutical industry
compensation surveys or the prevailing competitive salaries in the biotechnology
sector for similar positions and by evaluating those salary standards against
the achievement by the Company of its corporate goals. The compensation of the
Company's executive officers was compared to equivalent data in the surveys and
competitive market compensation levels to determine base salary. Base salaries
for executive officers were increased by 0% to 4% for fiscal 2000 compared to
fiscal 1999. The increases were due to 1999 Company performance and the need to
remain within the range of competitive salaries for comparable companies.

         Bonus Compensation. The Committee also provides executive officers and
other senior managers of the Company the opportunity earn annual cash bonuses.
The actual bonus award earned depends on the extent to which Company and
individual performance objectives are achieved. At the start of each year, the
Committee and the full Board of Directors review and approve the annual
performance objectives for the Company. The Company objectives consist of
operating, strategic and financial goals that are considered to be critical to
the Company's fundamental long-term goal--building stockholder value.

         Stock Options. The Company's stock option plan has been established to
provide all employees of the Company, including executive officers, with an
opportunity to share along with stockholders of the Company, in the benefits
deriving from the long-term performance of the Company. Stock options


                                       19
   22


typically have been granted to executive officers when the executive first joins
the Company, in connection with a significant change in responsibilities and
occasionally, to achieve equity within a peer group. The Committee may grant
additional stock options to executives to continue to retain such executives and
provide incentives. The number of shares subject to each stock option granted is
based on anticipated future contribution and ability to impact corporate
results. In 2000, stock options were granted which become exercisable over a
four-year period or cliff vest after seven years or earlier at the discretion of
the Board. These options were granted at a price that is equal to the fair
market value of the Company's Common Stock on the date of grant.


2000 CEO COMPENSATION.

         Dr. Hoffman's base salary, bonus and grants of stock options were
determined with the criteria described in the above sections of this report. Dr.
Hoffman's base salary was considered competitive and remained at $225,000 in
fiscal 2000. Dr. Hoffman's fiscal 2000 cash bonus of $68,750 awarded in July
2000 was based upon achieving the following corporate goals: completing an End
of Phase II Oncology meeting with the FDA, beginning a Phase III clinical study
and obtaining adequate financing via an initial public offering.

         The periodic stock option grant to Dr. Hoffman in January 2000 of
options to purchase 328,971 shares of Common Stock of the Company at 100% of
fair market value on the date of grant, or $2.42 per share, also reflects the
Board's assessment of the substantial contributions made by Dr. Hoffman to the
growth and performance of the Company.

LIMITATION ON DEDUCTION OF COMPENSATION PAID TO CERTAIN EXECUTIVE OFFICERS.

         Section 162(m) of the Code limits the Company to a deduction for
federal income tax purposes of no more than $1 million of compensation paid to
certain Named Executive Officers in a taxable year. Compensation above $1
million may be deducted if it is "performance-based compensation" within the
meaning of the Code.

         The statute containing this law and the applicable proposed Treasury
regulations offer a number of transitional exceptions to this deduction limit
for pre-existing compensation plans, arrangements and binding contracts. As a
result, the Compensation Committee believes that at the present time it is quite
unlikely that the compensation paid to any Named Executive Officer in a taxable
year which is subject to the deduction limit will exceed $1 million. Therefore,
the Compensation Committee has not yet established a policy for determining
which forms of incentive compensation awarded to its Named Executive Officers
shall be designed to qualify as "performance-based compensation."

         Prior to the date of this proxy statement, the members of the Committee
resigned in connection with their resignation from the Board and were replaced
by Dr. Jaffe and Mr. Edwards. The Company does not expect a significant change
in its present compensation program with the appointment of the new members of
the Committee, although a review of compensation policies by the new members
could result in changes to the Company's compensation program. The preceding
report is based upon information available to the current members of the
Committee about the Company's compensation program as it was implemented by the
previous members of the Committee.

                                                COMPENSATION COMMITTEE

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

         As noted above, the Company's compensation committee consists of Dr.
Jaffe and Mr. Edwards. None of the Company's executive officers serve as members
of the board of directors or compensation committee of any entity that has one
or more executive officers who serve on the Company's Board of Directors or
compensation committee.

                              CERTAIN TRANSACTIONS

         In March 1996, the Company received a recourse note from Dr. Hoffman in
the aggregate principal amount of $64,000 upon exercise of options to acquire
396,800 shares of Common Stock. This note accrued interest at 8% annually and
was due in March 2000. In March 2000, however, the Company forgave this note and
all accrued interest thereon.

         The Company has entered into agreements to indemnify our directors and
executive officers which provide, among other things, that the Company will
indemnify such executive officer or director for certain expenses including
attorneys' fees, judgments, fines and settlement amounts incurred by any such
person in any action or proceeding, services as a director, officer, employee,
agent or fiduciary of the Company, any subsidiary of the Company or any other
company or enterprise to which such executive officer or director serves at our
request. We believe that these provisions and agreements are necessary to
attract and retain qualified persons as directors and executive officers.

                         CHARTER OF THE AUDIT COMMITTEE
                          OF THE BOARD OF DIRECTORS OF
                            ALLOS THERAPEUTICS, INC.

STATEMENT OF POLICY

         The audit committee shall provide assistance to the corporate directors

independent auditors, and the financial management of the corporation.

COMPOSITION

         The audit committee shall be composed of at least three (3) directors

of the audit committee will serve at the discretion of the Board.

RESPONSIBILITIES

In carrying out its responsibilities, the audit committee believes its policies
and procedures should remain flexible, in order to best react to changing

     selected to audit the financial statements of the corporation and its
     divisions and subsidiaries.

o    Meet with the independent auditors and financial management of the
     corporation to review the scope of the proposed audit for the current year

     review such audit, including any comments or recommendations of the
     independent auditors.

o    Review with the independent auditors, and financial and accounting
     personnel, the adequacy and effectiveness of the accounting and financial
     controls of the corporation, and elicit any recommendations for the
     improvement of such internal control procedures or particular areas where
     new or more detailed controls or procedures are desirable. Particular
     emphasis should be given to the adequacy of such internal controls to
     expose any payments, transactions, or procedures that might be deemed
     illegal or otherwise improper.

o    Review the financial statements contained in the annual report to
     shareholders with management and the independent auditors to determine that
     the independent auditors are satisfied with the disclosure and content of
     the financial statements to be presented to the shareholders. Any changes
     in accounting principles should be reviewed.


   27


o    Provide sufficient opportunity for the independent auditors to meet with
     the members of the audit committee without members of management present.

o    Review accounting and financial human resources and succession planning
     within the company.

o    Submit the minutes of all meetings of the audit committee to, or discuss
     the matters discussed at each committee meeting with, the board of
     directors.

o    Investigate any matter brought to its attention within the scope of its
     duties, with the power to retain outside counsel for this purpose if, in
     its judgment, that is appropriate.

MEETINGS

         The Committee will hold at least one regular meeting per year and
additional meetings as the Committee deems appropriate. The Chairman of the
Board, the Chief Executive Officer and the Chief Financial Officer of the
Company may attend any meeting of the Committee, except for portions of the
meetings where such presence would be inappropriate, as determined by the
Committee.

within the limitations of, the express provisions of the Plan:

                  (i) To determine when and how Purchase Rights to purchase

such Purchase Rights (which need not be identical).

                  (ii) To designate from time to time which Related Corporations

the Plan, in a manner and to the extent it shall deem necessary or expedient to

the Board composed of one (1) or more members of the Board. If administration is
delegated to a Committee, the Committee shall have, in connection with the
administration of the Plan, the powers theretofore possessed by the Board,

4.       SHARES OF COMMON STOCK SUBJECT TO THE PLAN.

         (a) Subject to the provisions of Section 14 relating to adjustments

Purchase Rights granted under the Plan shall not exceed in the aggregate one
million five hundred thousand (1,500,000) shares of Common Stock, plus an annual
increase to be added on the first day of each calendar year, commencing on
January 1, 2002 and ending on (and including) January 1, 2011, equal to the
lesser of (i) two percent (2%) of the shares of Common Stock outstanding on each
January 1 (rounded down to the nearest whole share and calculated on a fully
diluted basis, that is assuming the exercise of all outstanding stock options
and warrants to purchase shares of Common Stock) or (ii) four hundred forty
thousand (440,000) shares of Common Stock; provided, however, that the Board may
determine a lesser number of shares of Common Stock than each of (i) and (ii).
Notwithstanding the foregoing, any such automatic share reserve increases in the
aggregate shall not exceed one million (1,000,000) shares of Common Stock. If
any Purchase Right granted under the Plan shall for any reason terminate without
having been exercised, the shares not purchased under such Purchase Right shall
again become available for issuance under the Plan.

         (b) The shares of Common Stock subject to the Plan may be unissued
shares or shares that have been bought on the open market at prevailing market
prices or otherwise.

5.       GRANT OF PURCHASE RIGHTS; OFFERING.

         (a) The Board may from time to time grant or provide for the grant of
Purchase Rights to purchase shares of Common Stock under the Plan to Eligible
Employees in an Offering (consisting of one or more Purchase Periods) on an
Offering Date or Offering Dates selected by the Board. Each Offering shall be in
such form and shall contain such terms and conditions as the Board shall deem
appropriate, which shall comply with the requirement of Section 423(b)(5) of the
Code that all Employees granted Purchase Rights to purchase shares of Common
Stock under the Plan shall have the same rights and privileges. The terms and
conditions of an Offering shall be incorporated by reference into the Plan and
treated as part of the Plan. The provisions of separate Offerings need not be
identical, but each Offering shall include (through incorporation of the
provisions of this Plan by reference in the document comprising the Offering or
otherwise) the period during which the Offering shall be effective, which period
shall not exceed twenty-seven (27) months beginning with the Offering Date, and
the substance of the provisions contained in Sections 6 through 9, inclusive.

         (b) If a Participant has more than one Purchase Right outstanding under
the Plan, unless he or she otherwise indicates in agreements or notices
delivered hereunder: (i) each agreement or notice delivered by that Participant
shall be deemed to apply to all of his or her Purchase Rights under the Plan,
and (ii) a Purchase Right with a lower exercise price (or an earlier-granted
Purchase Right, if different Purchase Rights have identical exercise prices)
shall be exercised to the fullest possible extent before a Purchase Right with a
higher exercise price (or a later-granted Purchase Right, if different Purchase
Rights have identical exercise prices) shall be exercised.

6.       ELIGIBILITY.

         (a) Purchase Rights may be granted only to Employees of the Company or,
as the Board may designate as provided in Section 3(b), to Employees of a
Related Corporation. Except as provided in Section 6(b), an Employee shall not
be eligible to be granted Purchase Rights under the Plan unless, on the Offering
Date, such Employee has been in the employ of the Company or the Related
Corporation, as the case may be, for such continuous period preceding such
Offering Date as the Board may require, but in no event shall the required
period of continuous employment be greater than two (2) years. In addition, the
Board may provide that no Employee shall be eligible to be granted Purchase
Rights under the Plan unless, on the Offering Date, such Employee's customary
employment with the Company or the Related Corporation is more than twenty (20)
hours per week and more than five (5) months per calendar year.

         (b) The Board may provide that each person who, during the course of an
Offering, first becomes an Eligible Employee shall, on a date or dates specified
in the Offering which coincides with the day on which such person becomes an
Eligible Employee or which occurs thereafter, receive a Purchase Right under
that Offering, which Purchase Right shall thereafter be deemed to be a part of
that Offering. Such Purchase Right shall have the same characteristics as any
Purchase Rights originally granted under that Offering, as described herein,
except that:


                                      -5-
   33


                  (i) the date on which such Purchase Right is granted shall be
the "Offering Date" of such Purchase Right for all purposes, including
determination of the exercise price of such Purchase Right;

                  (ii) the period of the Offering with respect to such Purchase
Right shall begin on its Offering Date and end coincident with the end of such
Offering; and

                  (iii) the Board may provide that if such person first becomes
an Eligible Employee within a specified period of time before the end of the
Offering, he or she shall not receive any Purchase Right under that Offering.

         (c) No Employee shall be eligible for the grant of any Purchase Rights
under the Plan if, immediately after any such Purchase Rights are granted, such
Employee owns stock possessing five percent (5%) or more of the total combined
voting power or value of all classes of stock of the Company or of any Related
Corporation. For purposes of this Section 6(c), the rules of Section 424(d) of
the Code shall apply in determining the stock ownership of any Employee, and
stock which such Employee may purchase under all outstanding Purchase Rights and
options shall be treated as stock owned by such Employee.

         (d) As specified by Section 423(b)(8) of the Code, an Eligible Employee
may be granted Purchase Rights under the Plan only if such Purchase Rights,
together with any other rights granted under all Employee Stock Purchase Plans
of the Company and any Related Corporations, do not permit such Eligible
Employee's rights to purchase stock of the Company or any Related Corporation to
accrue at a rate which exceeds twenty five thousand dollars ($25,000) of Fair
Market Value of such stock (determined at the time such rights are granted, and
which, with respect to the Plan, shall be determined as of their respective
Offering Dates) for each calendar year in which such rights are outstanding at
any time.

         (e) Officers of the Company and any designated Related Corporation, if
they are otherwise Eligible Employees, shall be eligible to participate in
Offerings under the Plan. Notwithstanding the foregoing, the Board may provide
in an Offering that Employees who are highly compensated Employees within the
meaning of Section 423(b)(4)(D) of the Code shall not be eligible to
participate.

7.       PURCHASE RIGHTS; PURCHASE PRICE.

         (a) On each Offering Date, each Eligible Employee, pursuant to an
Offering made under the Plan, shall be granted a Purchase Right to purchase up
to that number of shares of Common Stock purchasable either with a percentage or
with a maximum dollar amount, as designated by the Board, but in either case not
exceeding ten percent (10%), of such Employee's Earnings (as defined by the
Board in each Offering) during the period that begins on the Offering Date (or
such later date as the Board determines for a particular Offering) and ends on
the date stated in the Offering, which date shall be no later than the end of
the Offering.


                                      -6-
   34


         (b) The Board shall establish one (1) or more Purchase Dates during an
Offering as of which Purchase Rights granted under the Plan and pursuant to that
Offering shall be exercised and purchases of shares of Common Stock shall be
carried out in accordance with such Offering.

         (c) In connection with each Offering made under the Plan, the Board may
specify a maximum number of shares of Common Stock that may be purchased by any
Participant on any Purchase Date during such Offering. In connection with each
Offering made under the Plan, the Board may specify a maximum aggregate number
of shares of Common Stock that may be purchased by all Participants pursuant to
such Offering. In addition, in connection with each Offering that contains more
than one Purchase Date, the Board may specify a maximum aggregate number of
shares of Common Stock that may be purchased by all Participants on any given
Purchase Date under the Offering. If the aggregate purchase of shares of Common
Stock issuable upon exercise of Purchase Rights granted under the Offering would
exceed any such maximum aggregate number, then, in the absence of any Board
action otherwise, a pro rata allocation of the shares of Common Stock available
shall be made in as nearly a uniform manner as shall be practicable and
equitable.

         (d) The purchase price of shares of Common Stock acquired pursuant to
Purchase Rights granted under the Plan shall be not less than the lesser of:

                  (i) an amount equal to eighty-five percent (85%) of the Fair
Market Value of the shares of Common Stock on the Offering Date; or

                  (ii) an amount equal to eighty-five percent (85%) of the Fair
Market Value of the shares of Common Stock on the applicable Purchase Date.

8.       PARTICIPATION; WITHDRAWAL; TERMINATION.

         (a) An Eligible Employee may become a Participant in the Plan pursuant
to an Offering by delivering a participation agreement to the Company within the
time specified in the Offering, in such form as the Company may provide. Each
such agreement shall authorize payroll deductions of up to the maximum
percentage specified by the Board of such Participant's Earnings (as defined in
each Offering) during the Offering. The payroll deductions made for each
Participant shall be credited to a bookkeeping account for such Participant
under the Plan and shall be deposited with the general funds of the Company. To
the extent provided in the Offering, a Participant may reduce (including to
zero) or increase such payroll deductions. To the extent provided in the
Offering, a Participant may begin such payroll deductions after the beginning of
the Offering. A Participant may make additional payments into his or her account
only if specifically provided for in the Offering and only if the Participant
has not already had the maximum permitted amount withheld during the Offering.

         (b) At any time during an Offering, a Participant may terminate his or
her payroll deductions under the Plan and withdraw from the Offering by
delivering to the Company a notice of withdrawal in such form as the Company may
provide. Such withdrawal may be elected at any time prior to the end of the
Offering, except as provided in the Offering. Upon such withdrawal from the
Offering by a Participant, the Company shall distribute to such


                                      -7-
   35


Participant all of his or her accumulated payroll deductions (reduced to the
extent, if any, such deductions have been used to acquire shares of Common Stock
for the Participant) under the Offering, without interest (unless otherwise
specified in the Offering), and such Participant's interest in that Offering
shall be automatically terminated. A Participant's withdrawal from an Offering
shall have no effect upon such Participant's eligibility to participate in any
other Offerings under the Plan, but such Participant shall be required to
deliver a new participation agreement in order to participate in subsequent
Offerings under the Plan.

         (c) Purchase Rights granted pursuant to any Offering under the Plan
shall terminate immediately upon a Participant ceasing to be an Employee for any
reason or for no reason (subject to any post-employment participation period
required by law) or other lack of eligibility. The Company shall distribute to
such terminated or otherwise ineligible Employee all of his or her accumulated
payroll deductions (reduced to the extent, if any, such deductions have been
used to acquire shares of Common Stock for the terminated or otherwise
ineligible Employee) under the Offering, without interest (unless otherwise
specified in the Offering).

         (d) Purchase Rights granted under the Plan shall not be transferable by
a Participant otherwise than by will or the laws of descent and distribution, or
by a beneficiary designation as provided in Section 13 and, during a
Participant's lifetime, shall be exercisable only by such Participant.

9.       EXERCISE.

         (a) On each Purchase Date during an Offering, each Participant's
accumulated payroll deductions and other additional payments specifically
provided for in the Offering (without any increase for interest) shall be
applied to the purchase of shares of Common Stock up to the maximum number of
shares of Common Stock permitted pursuant to the terms of the Plan and the
applicable Offering, at the purchase price specified in the Offering. No
fractional shares shall be issued upon the exercise of Purchase Rights granted
under the Plan unless specifically provided for in the Offering.

         (b) If any amount of accumulated payroll deductions remains in a
Participant's account after the purchase of shares of Common Stock and such
remaining amount is less than the amount required to purchase one share of
Common Stock on the final Purchase Date of an Offering, then such remaining
amount shall be held in each such Participant's account for the purchase of
shares of Common Stock under the next Offering under the Plan, unless such
Participant withdraws from such next Offering, as provided in Section 8(b), or
is not eligible to participate in such Offering, as provided in Section 6, in
which case such amount shall be distributed to the Participant after said final
Purchase Date, without interest (unless otherwise specified in the Offering). If
any amount, of accumulated payroll deductions remains in a Participant's account
after the purchase of shares of Common Stock and such remaining amount is equal
to the amount required to purchase one (1) or more whole shares of Common Stock
on the final Purchase Date of the Offering, then such remaining amount shall be
distributed in full to the Participant at the end of the Offering without
interest (unless otherwise specified in the Offering).


                                      -8-
   36


         (c) No Purchase Rights granted under the Plan may be exercised to any
extent unless the shares of Common Stock to be issued upon such exercise under
the Plan are covered by an effective registration statement pursuant to the
Securities Act and the Plan is in material compliance with all applicable
federal, state, foreign and other securities and other laws applicable to the
Plan. If on a Purchase Date during any Offering hereunder the shares of Common
Stock are not so registered or the Plan is not in such compliance, no Purchase
Rights granted under the Plan or any Offering shall be exercised on such
Purchase Date, and the Purchase Date shall be delayed until the shares of Common
Stock are subject to such an effective registration statement and the Plan is in
such compliance, except that the Purchase Date shall not be delayed more than
twelve (12) months and the Purchase Date shall in no event be more than
twenty-seven (27) months from the Offering Date. If, on the Purchase Date under
any Offering hereunder, as delayed to the maximum extent permissible, the shares
of Common Stock are not registered and the Plan is not in such compliance, no
Purchase Rights granted under the Plan or any Offering shall be exercised and
all payroll deductions accumulated during the Offering (reduced to the extent,
if any, such deductions have been used to acquire shares of Common Stock) shall
be distributed to the Participants, without interest (unless otherwise specified
in the Offering).

10.      COVENANTS OF THE COMPANY.

         (a) During the terms of the Purchase Rights granted under the Plan, the
Company shall ensure that the amount of shares of Common Stock required to
satisfy such Purchase Rights are available.

         (b) The Company shall seek to obtain from each federal, state, foreign
or other regulatory commission or agency having jurisdiction over the Plan such
authority as may be required to issue and sell shares of Common Stock upon
exercise of the Purchase Rights granted under the Plan. If, after reasonable
efforts, the Company is unable to obtain from any such regulatory commission or
agency the authority that counsel for the Company deems necessary for the lawful
issuance and sale of shares of Common Stock under the Plan, the Company shall be
relieved from any liability for failure to issue and sell shares of Common Stock
upon exercise of such Purchase Rights unless and until such authority is
obtained.

11.      USE OF PROCEEDS FROM SHARES OF COMMON STOCK.

         Proceeds from the sale of shares of Common Stock pursuant to Purchase
Rights granted under the Plan shall constitute general funds of the Company.

12.      RIGHTS AS A STOCKHOLDER.

         A Participant shall not be deemed to be the holder of, or to have any
of the rights of a holder with respect to, shares of Common Stock subject to
Purchase Rights granted under the Plan unless and until the Participant's shares
of Common Stock acquired upon exercise of Purchase Rights granted under the Plan
are recorded in the books of the Company (or its transfer agent).

13.      DESIGNATION OF BENEFICIARY.

         (a) A Participant may file a written designation of a beneficiary who
is to receive any shares of Common Stock and/or cash, if any, from the
Participant's account under the Plan in the event of such Participant's death
subsequent to the end of an Offering but prior to delivery to the Participant of
such shares of Common Stock or cash. In addition, a Participant may file a
written designation of a beneficiary who is to receive any cash from the
Participant's account under the Plan in the event of such Participant's death
during an Offering.

         (b) The Participant may change such designation of beneficiary at any
time by written notice. In the event of the death of a Participant and in the
absence of a beneficiary validly designated under the Plan who is living at the
time of such Participant's death, the Company shall deliver such shares of
Common Stock and/or cash to the executor or administrator of the estate of the
Participant, or if no such executor or administrator has been appointed (to the
knowledge of the Company), the Company, in its sole discretion, may deliver such
shares of Common Stock and/or cash to the spouse or to any one or more
dependents or relatives of the Participant, or if no spouse, dependent or
relative is known to the Company, then to such other person as the Company may
designate.

14.      ADJUSTMENTS UPON CHANGES IN SECURITIES; CORPORATE TRANSACTIONS.

         (a) If any change is made in the shares of Common Stock, subject to the
Plan, or subject to any Purchase Right, without the receipt of consideration by
the Company (through merger, consolidation, reorganization, recapitalization,
reincorporation, stock dividend, dividend in property other than cash, stock
split, liquidating dividend, combination of shares, exchange of shares, change
in corporate structure or other transaction not involving the receipt of
consideration by the Company), the Plan shall be appropriately adjusted in the
type(s), class(es) and maximum number of shares of Common Stock subject to the
Plan pursuant to Section 4(a), and the outstanding Purchase Rights granted under
the Plan shall be appropriately adjusted in the type(s), class(es), number of
shares and purchase limits of such outstanding Purchase Rights. The Board shall
make such adjustments, and its determination shall be final, binding and
conclusive. (The conversion of any convertible securities of the Company shall
not be treated as a "transaction not involving the receipt of consideration by
