                                 PROXY STATEMENT
                                  ____________

     These proxy materials are furnished to the stockholders of Heska
Corporation, a Delaware corporation in connection with the solicitation of
proxies to be used in voting at our 2001 Annual Meeting of Stockholders and at
any adjournment or postponement thereof.  THE ENCLOSED PROXY IS SOLICITED BY OUR
BOARD OF DIRECTORS.

     You are invited to attend our Annual Meeting of Stockholders to be held on
May 17, 2001, beginning at 9:00 a.m.  The meeting will be held at Heska
Corporation, 1613 Prospect Parkway, Fort Collins, Colorado.

     This Proxy Statement, proxy card and voting instructions are being mailed
starting April 4, 2001.

STOCKHOLDERS ENTITLED TO VOTE

     Stockholders of record at the close of business on March 23, 2001 are
entitled to notice of and to vote at the Annual Meeting.  As of that date, we
had 38,656,745 shares of common stock outstanding. Each holder of common stock
is entitled to one vote for each share held as of the record date.  An
inspector of elections appointed by the Board of Directors will determine the
shares represented at the Annual Meeting, the validity of proxies and will
count all votes.  Determinations of whether a quorum exists and whether
proposals are approved will be announced at the Annual Meeting.

PROXIES

     Your vote is important.  Stockholders of record may vote their proxies by
Internet or mail.  The web site address is included on your proxy card.  If you
choose to vote by mail, a postage-paid envelope is provided.

     A proxy may be revoked at any time before it is exercised by (1) filing a
written revocation with the Secretary of the Company, (2) submitting a duly
executed proxy bearing a later date, or (3) voting by ballot at the Annual
Meeting.

Vote by Internet

     You can vote your shares via the Internet.  The web site for Internet
voting is on your proxy card.  Internet voting is available 24 hours a day.  You
will be given the opportunity to confirm that your instructions have been
properly recorded.  If you vote via the Internet you do not need to return your
proxy card.

Vote by Mail

     If you choose to vote by mail, simply mark your proxy, date and sign it,
and return it to Computershare Trust Company, Inc. in the postage-paid envelope
provided.

Voting at the Annual Meeting

     The method by which you vote now will in no way limit your right to vote at
the Annual Meeting if you decide to attend in person.  If your shares are held
in the name of a bank, broker or other holder of record, you must obtain a
proxy, executed in your favor, from the holder of record and bring it with you
to the meeting to be able to vote at the meeting.

     All proxies returned prior to the Annual Meeting will be voted in
accordance with the instructions contained therein.  If no choice is specified,
the shares will be voted FOR the proposals listed in this Proxy Statement.

Voting of Other Matters

     The enclosed proxy card grants the proxy holders discretionary authority to
vote on other matters properly brought before the Annual Meeting.  At the date
this Proxy Statement went to press, we did not know of any other matter to be
raised at the Annual Meeting.

LIST OF STOCKHOLDERS

     A list of stockholders entitled to vote at the Annual Meeting will be
available at the Annual Meeting and for ten days prior to the meeting during
normal business hours at our offices at 1612 Specht Point Drive, Fort Collins,
Colorado, 80525, by contacting the Secretary of the Company.

REQUIRED VOTE

     The presence in person or by proxy of the holders of a majority of our
outstanding shares constitutes a quorum for the transaction of business at the
Annual Meeting.  Abstentions and broker "non-votes" are counted as present and
entitled to vote for purposes of determining a quorum.

     Directors are elected by a plurality vote.  Any other matter submitted for
stockholder approval at the Annual Meeting, will be decided by the affirmative
vote of a majority of shares present in person or represented by valid proxy and
entitled to vote on each such matter.  Abstentions with respect to any matter
are treated as shares present or represented and entitled to vote on that matter
and thus have the same effect as negative votes.  If a broker, bank or other
nominee, who is the record holder of certain shares indicates on a proxy that it
does not have discretionary authority to vote on a particular matter as to such
shares, or if shares are not voted in other circumstances in which proxy
authority is defective or has been withheld with respect to any matter, these
"non-voted" shares will be counted for quorum purposes but will not be counted
in determining whether stockholder approval of a particular matter has been
obtained.

COST OF SOLICITATION

     We will bear the expense of soliciting proxies, including the expense of
preparing, printing and mailing proxy materials.  In addition to the
solicitation of proxies by mail, solicitation may be made by certain of our
directors, officers and other employees by personal interview, telephone or
facsimile.  No additional compensation will be paid to these people for such
solicitation.

                        PROPOSAL 1 - ELECTION OF DIRECTOR


DIRECTORS AND NOMINEE FOR DIRECTOR

     There is one Class I nominee for election this year.  Detailed information
on this nominee is provided on page 3 of this proxy statement.  Our Board of
Directors is divided into three classes, with one class of directors elected
each year at the Annual Meeting of Stockholders for a three-year term of office.
The directors of each class hold their positions until the Annual Meeting of
Stockholders at which time their respective successors are elected and qualified
or until their earlier resignation, removal from office, death or incapacity.
One Class I director is to be elected at this meeting for a three-year term
ending in 2004.

     The Board of Directors proposes the election of Dr. Edith W. Martin as a
Class I director.  The persons named on the enclosed proxy card intend to vote
the proxy for the election of this nominee, unless you indicate on the proxy
card that your vote should be withheld from such nominee.  If you are voting by
Internet, you will be instructed how to withhold your vote.  Dr. Martin has
indicated her willingness to serve as a member of the Board of Directors if
elected; however, if she is unable or declines to serve as a director at the
time of the Annual Meeting, an event not now anticipated, proxies will be voted
for a nominee designated by the Board of Directors to fill the vacancy.
Stockholder nominations for the Board of Directors must be made following the
procedures set forth in the Bylaws not less than 60 days nor more than 90 days
prior to the scheduled date of the Annual Meeting.  The deadline for a
stockholder to deliver notice of a nomination for the election of directors at
the 2001 Annual Meeting of Stockholders was March 16, 2001.  No such nominations
were received.

     There is currently a vacancy in Class I of the Board of Directors.  We
intend to fill such vacancy with an independent director.

THE  BOARD  OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR THE ELECTION  OF  DR.
MARTIN AS OUR DIRECTOR.

BOARD AND COMMITTEE MEMBERSHIP AND MEETINGS

     During 2000, the Board of Directors had two ongoing committees.  Those
committees consisted of an Audit Committee and a Compensation Committee.  The
Compensation Committee and Audit Committee are comprised entirely of non-
employee directors.  There is no family relationship among any of the directors
or the nominee.

     Except as noted below, all directors attended at least 75% of the aggregate
number of meetings of the Board of Directors and Board committees on which they
served during their respective terms of office.  The Board of Directors held six
meetings during the year ended December 31, 2000.

     The members of the Compensation Committee during 2000 were Mr. Dolan, Dr.
Hohnke and Mr. Sasen.  Dr. Martin was appointed to the Compensation Committee in
October 2000.  The Compensation Committee held four meetings during 2000.  Dr.

Compensation Committee's functions are to make recommendations to the Board of
Directors with respect to general and specific compensation policies and
practices and to administer the 1997 Stock Incentive Plan and 1997 Employee
Stock Purchase Plan.

     The members of the Audit Committee during 2000 were Mr. Dolan, Mr. Pomroy

Pomroy resigned in June 2000.  Dr. Martin was appointed to the Audit Committee

advise and assist the Board of Directors in evaluating the auditor's
examination, and provide oversight in connection with our financial and
accounting organization and financial reporting.

RELATIONSHIP WITH INDEPENDENT PUBLIC ACCOUNTANTS

     Upon the recommendation of the Audit Committee, the Board of Directors has
selected Arthur Andersen LLP as the independent public accounting firm to audit
our financial statements for the fiscal year beginning January 1, 2001.

     Representatives of Arthur Andersen LLP will be present at the meeting.
They will be given the opportunity to make a statement if they desire to do so,
and they will be available to respond to appropriate questions.

DIRECTORS' COMPENSATION

     Each new outside director elected to our Board of Directors is
automatically granted as of the date of election an option to purchase 10,000
shares of common stock at an exercise price equal to the fair market value of
the common stock on the date of grant.  The shares subject to these options vest
in four equal installments at annual intervals over the four-year period
commencing on the date of grant.  Further, each outside director who continues
to serve in such capacity following any annual meeting of stockholders is
automatically granted an option as of the date of such meeting to purchase 2,000
shares of common stock at an exercise price equal to the fair market value of
the common stock on the date of grant.  The shares subject to these options vest
on the first anniversary of grant.  No director is eligible to receive the
10,000-share grant and a 2,000-share grant in the same year.  Directors are
eligible to receive a greater number of options or shares than the automatic
grants described above under the 1997 Stock Incentive Plan.  The Board of
Directors has approved, subject to stockholder approval, an amendment to the
1997 Stock Incentive Plan to increase the number of options granted annually to
outside directors.  See "Proposal 2" herein.

     In February 2001, the Board of Directors modified the existing policy to
compensate "outside" or non-employee directors with options to purchase Heska
common stock.  Under this new policy, outside directors receive an option to
purchase 200 shares for attendance at a meeting of the Board of Directors, or
Board committee, which is less than four hours and an option to purchase 1,000
shares for attendance at a meeting of the Board of Directors, or Board
committee, which is four hours or more, or for consulting services of four hours
or more.  These options are immediately exercisable and the exercise price is
equal to the fair market value on the date of grant.  Directors are reimbursed
for their reasonable expenses for each meeting attended.

     See "Employment Agreements" below for a description of the compensation
arrangement with Dr. Grieve.

     Mr. Dolan was appointed to our Board of Directors in connection with equity

PENSION AND LONG-TERM INCENTIVE PLANS

     We have no pension or long-term incentive plans.

EMPLOYMENT AGREEMENTS

     During 2000, we were a party to employment agreements with each of the
named executive officers.  All of the agreements provide for severance payments
if the individual's employment is terminated without cause, including
terminations in connection with a change in control.  In the case of Dr. Grieve,
the payments set forth in his employment agreement are equal to one year's
salary plus an additional year of vesting under any stock arrangements if his
employment is involuntarily terminated.  In the case of Mr. Fuller, the payments
set forth in his employment agreement are equal to one year's salary plus an
additional one year's vesting under any stock arrangements if the termination
takes place any time on or before January 18, 2002, or six months' salary and an
additional six months' vesting under any stock arrangements if the termination
takes place after that date.  In the case of Mr. Hendrick, the payments set
forth in his employment agreement are equal to one year's salary if the
termination takes place any time on or before December 1, 2001, or six months'
salary if the termination takes place after that date.  In the case of Dr.
Miozzari, the payments (including amounts mandated by Swiss law) would be six
months' salary if he is terminated without cause other than a change in control,
or one year's salary if he is terminated without cause due to a change in
control.  In the case of Dr. Stinchcomb, the payments set forth in this
employment agreement are equal to six months' salary if he is terminated without
cause other than a change in control, or one year's salary if he is terminated
without cause due to a change in control.

COMPENSATION PHILOSOPHY AND OBJECTIVES

     We believe that compensation of the Company's executive officers should
promote the success of the Company by attracting, retaining and motivating all
employees, including executive officers, while aligning their interests with the
Company's long-term and strategic interests and the interests of stockholders.
Competition for skilled employees, particularly management level employees, in
the Company's industry is intense and the Committee seeks to provide total
compensation packages that will attract and retain superior caliber individuals,
yet be consistent with the Company's financial situation and stage of
development.

KEY ELEMENTS OF EXECUTIVE COMPENSATION

     Until the Company has achieved operational profitability, we believe that
the use of traditional performance standards, such as profit levels and return
on equity, are not appropriate in the evaluation of executive officer
performance.  Instead, the Committee evaluates the performance of executive
officers and sets their compensation based primarily on the Company's
achievement of its business objectives, such as developing and introducing
products, obtaining appropriate financing, developing its intellectual property
portfolio and entering into collaborations with other companies and academia.
The Committee also evaluates each officer's individual contribution toward the
achievement of these objectives and of other individual objectives.  Currently,
the Company's compensation structure for executive officers includes a
combination of base salary, stock options and performance based cash incentive
under a management incentive compensation plan.

     Base Salary.  Salary levels are largely determined through comparisons with
companies of similar headcount and market capitalizations or complexity in the
biotechnology industry.  Actual salaries are based on individual performance
contributions within a competitive salary range for each position that is
established through evaluation of responsibilities and market comparisons.  We
believe, that the Company's salary levels for the executive officers are at a
level that, at the time such salary determinations were made, were considered to
be reasonable and necessary given the Company's financial resources and the
stage of its development.  This belief is based on our knowledge of executive
compensation in the industry and based on practices of comparable companies in
the Company's industry.

     Stock Options.  We believe that stock options provide excellent long-term
incentives for executive officers to increase the Company's market value for the
benefit of all stockholders.  We are responsible for determining the number and
terms of options to be granted to executive officers, taking into account such
factors as individual and Company performance, policies regarding cash
compensation and practices of comparable companies in the Company's industry.
Options granted to executive officers have exercise prices equal to fair market
value on the date of grant, vest over a four-year period and expire ten years
from the date of grant.  Vesting ceases and the vested portion of options must
be exercised should the executive leave the Company's employ (subject to any
rights to partial acceleration of vesting upon termination without cause under
employment agreements).  This Committee believes that these vesting provisions
help both to retain qualified employees and to motivate them to achieve long-
term increases in stock value, providing continuing benefits to the Company and
its stockholders beyond those in the year of grant.

     Management Incentive Compensation Plan.  We believe that cash performance
based incentives can also serve an important role in executive compensation.  We
have adopted a management incentive compensation plan which replaces the prior
executive bonus plan.  The management incentive compensation plan will provide
incentives to the executives of the Company to meet and exceed certain
predetermined annual net income and revenue goals. We have established these
financial goals for the 2001 calendar year, and any such incentives with respect
to the 2001 calendar year will only be paid after the audited financial results
for the year are available.  While we believe that providing cash bonuses to the
executives of the Company is an essential part of creating a competitive
executive compensation package, we have determined that paying the great
majority of such bonuses only if specific predetermined financial goals are
achieved provides a very strong incentive to the Company's management to achieve
financial performance that will be beneficial to the Company and its
stockholders.

CHIEF EXECUTIVE OFFICER COMPENSATION

     The annual salary of Robert B. Grieve, the Company's Chairman of the Board
and Chief Executive Officer, was increased to $260,000 in 2000, and we awarded
him a stock option in February 2000 to purchase an additional 200,000 shares of
common stock.  These options have the terms described above.  Given the
Company's stage of development, the use of traditional performance standards,
such as profit levels and return on equity, were not considered to be
appropriate in the evaluation of Dr. Grieve's performance.

QUALIFYING COMPENSATION

     It is the Company's policy generally to qualify compensation paid to
executive officers for deductibility under section 162(m) of the Internal
Revenue Code.  Section 162(m) generally prohibits the Company from deducting the
compensation of executive officers that exceeds $1,000,000 unless that
compensation is based on the satisfaction of objective performance goals.  The
Company's 1997 Stock Incentive Plan is structured to qualify awards under such
plans as performance-based compensation and to maximize the tax deductibility of
such awards.  However, the Company reserves the discretion to pay compensation
to its executive officers that may not be deductible.

                          REPORT OF THE AUDIT COMMITTEE


     The Audit Committee reviews the Company's accounting, auditing and
financial reporting practices on behalf of the Board of Directors.  The members
of the Audit Committee during 2000 were Mr. Dolan, Mr. Pomroy and Dr. Tebbit.
Mr. Aylesworth was appointed to the Audit Committee when Mr. Pomroy resigned in
June.  Dr. Martin was appointed to the Committee in October when Dr. Tebbit
resigned.  The members of this Audit Committee meet the independence and
experience requirements of the Nasdaq Stock Market.

     The Board of Directors has adopted a charter outlining the functions this
Committee is to perform.  A copy of this charter is attached to this proxy
statement as Appendix A.  These functions include:

     *    Monitoring the corporate financial reporting and internal and external
          audits of the Company;
     *    Providing the results of its examinations and recommendations derived
          therefrom to the Board of Directors; and
     *    Nominating independent auditors.

     In performing all of these functions, we act only in an oversight capacity.
We rely on the work and assurances of Company management, which has the primary
responsibility for the financial statements and reports, and of the independent
auditors, who, in their report, express an opinion on the conformity of the
Company's annual financial statements to generally accepted accounting
principles.

     In this context, during the year 2000, we met and held discussions with
management and the independent auditors. Management represented to us that the
Company's consolidated financial statements were prepared in accordance with
generally accepted accounting principles, and the Audit Committee has reviewed
and discussed the consolidated financial statements with management and the
independent auditors.  In our meetings with the independent auditors, we
discussed matters required to be discussed by the auditors with audit committees
under Statement of Auditing Standards No. 61 (Communication with Audit
Committees).

     In addition, we received and discussed with the auditors their annual
written report on their independence from the Company and its management which
is made under Independence Standards Board Standard No. 1 (Independence
Discussions with Audit Committees), and considered whether the provision of non-
audit services by the auditors was compatible with maintaining the auditor's
independence.

     In reliance on these reviews and discussions and the report of the
independent auditors, we have recommended to the Board of Directors, and the
Board has approved, that the audited financial statements be included in the
Company's Annual Report on Form 10-K for the year ended December 31, 2000, for
filing with the Securities and Exchange Commission.

                                        Respectfully submitted,

                                        William A. Aylesworth, Chairman
                                        A. Barr Dolan

             SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Compliance with Section 16(a) of the Securities Exchange Act of 1934
requires our directors, executive officers and persons who own more than 10% of
a registered class of our equity securities to file with the Securities and
Exchange Commission initial reports of ownership and reports of changes in
ownership of common stock and other of our equity securities.  Directors,
officers and 10% or greater stockholders are required by SEC regulations to
furnish us with copies of all of the Section 16(a) reports they file.  Based
solely upon a review of the copies of the forms furnished to us and the
representations made by the reporting persons to us, we believe that during
fiscal 2000 our directors, officers and 10% or greater stockholders complied
with all filing requirements under Section 16(a) of the Exchange Act.


                     CERTAIN TRANSACTIONS AND RELATIONSHIPS

COLLABORATIVE AGREEMENTS

Ralston Purina Company

     In July 1998, we entered into a Research and Licensing Agreement with
Ralston Purina.  Pursuant to that agreement, Ralston Purina acquired exclusive
rights to license certain of our discoveries, know-how and technologies for
innovative diets for dogs and cats, and we have agreed to allocate certain
resources to research, develop and commercialize pet food products that are the
subject of the collaboration.  The first product from this strategic alliance
was introduced by Ralston Purina in July 2000.  This new product is a specialty
diet for the nutritional management of feline diabetes mellitus.  We will
receive a royalty from Ralston Purina on sales of this product, as well as any
additional products developed under this collaboration.

     Also in July 1998, Ralston Purina acquired 1.165 million shares of our
common stock for $14.75 million in cash, and also acquired, for an additional
cash payment of $250,000, warrants to purchase an additional 1.165 million
shares of common stock.  The exercise price of the warrants is $12.67 for the
first year of the warrants, increasing by 20% per year for each of the second
and third years of the warrant.  The warrants were vested immediately as of
July 30, 1998 and expire on July 30, 2001 with respect to any unexercised
warrants.

Novartis

     Novartis, one of our principal stockholders, has ongoing marketing rights
to various of our products under development and is a party to a Screening and
Development Agreement and Right of First Refusal Agreement.  Novartis obtained
such rights in connection with its purchase of our preferred stock in April 1996
(which converted into common stock upon the closing of our initial public
offering), but did not make any separate payments for these rights.

     Effective as of August 18, 1998, we entered into an Exclusive Distribution
Agreement with Novartis Agro K.K., Tokyo, an affiliate of Novartis.  Under the
terms of the agreement Novartis Agro will have exclusive rights to market and
distribute selected Heska-branded products in Japan.  Novartis Agro is
responsible for the registration of these products in Japan.  The initial
product to be marketed under the agreement is Solo Step (TM) CH.  In
consideration of these distribution rights, Novartis has entered into a Right
of First Refusal Agreement wherein Novartis granted us a right of first refusal
to evaluate forpossible development and marketing worldwide certain new product
technologies for the veterinary market as they become available from Novartis.

     In January 2001, we entered into a distribution agreement with Novartis
Animal Health, Inc., granting them exclusive distribution rights for the sale of
our E-Screen (TM) test product in Europe.  In March 2001, we entered into a
distribution agreement with Novartis Animal Health Canada, Inc., granting them
exclusive distribution rights for the sale of our Flu Avert (TM) I.N. vaccine
in Canada.


     LOAN TO EXECUTIVE OFFICER

     In December 1999, we approved a personal loan to Dr. Grieve in the amount
of $100,000.  This loan is evidenced by a promissory note which is due and
payable on December 23, 2002.  Interest on the outstanding principal balance
accrues at the rate of 5.74% per annum.  Payment of any unpaid principal balance
together with all accrued and unpaid interest can be accelerated and become
payable within ninety days after Dr. Grieve's relationship with us is terminated
for any reason other than Dr. Grieve's death or permanent disability.


             PROPOSAL 2 - AMENDMENT TO THE 1997 STOCK INCENTIVE PLAN

SUMMARY OF 1997 STOCK INCENTIVE PLAN

     The Board of Directors and stockholders approved the 1997 Stock Incentive
Plan in March 1997.  The purpose of the Plan is to promote our long-term success
and the creation of stockholder value by (a) encouraging employees, outside
directors and consultants to focus on critical long-range objectives, (b)
encouraging the attraction and retention of employees, outside directors and
consultants with exceptional qualification, and (c) linking employees, outside
directors and consultants directly to stockholder interests through increased
stock ownership.  The Plan seeks to achieve this purpose by providing awards in
the form of incentive and non-qualified stock options ("NQO") to purchase our
common stock.  As of January 1, 2001, a total of 7,643,853 shares of our common
stock was available for issuance under the Plan.  The aggregate number of shares
issuable under the Plan and the aggregate amount issuable to any one participant
are subject to adjustment in the event of any change to our common stock due to
a stock split or recapitalization, stock dividend or other similar action or
event.

     It is our practice to grant all stock options at an exercise price equal to
the closing price of our stock on the date of grant.  However, the Plan provides
for the grant of non-qualified stock options at a discount of no more than 15%.
The Compensation Committee fixes the term and conditions of each option at the
time of grant, the term generally is ten years from the date of grant.

     All regular full-time U. S. employees receive incentive stock options and
all regular full-time European employees receive non-qualified stock options
when they are hired.  Additional options may be granted based upon merit. All
employee grants vest monthly over a four-year period.  As of January 1, 2001, we
had approximately 335 employees and 18 consultants which had been granted stock
options.

     The exercise price of options granted under the Plan, including applicable
tax withholding, if any, must be paid in full at the time of exercise.  The
method of payment is determined by the Compensation Committee and may consist of
cash, other shares of common stock, promissory note or irrevocable directions to
a securities broker to sell all or part of the option shares and to deliver the
sale proceeds to us.

     Currently, outside directors receive an automatic grant of an immediately
exercisable non-qualified option to purchase 10,000 shares of stock when they
first join the Board.  This option is subject to repurchase by us at the
exercise price if the director's service terminates for any reason.  This right
to repurchase lapses in four equal installments at annual intervals over a 48-
month period commencing on the date of grant.  In addition, each non-employee
director who will continue serving as a member of the Board upon the conclusion
of each annual meeting of stockholders receives an immediately exercisable non-
qualified option to purchase 2,000 shares of stock.  These options are also
subject to repurchase for a period of one year from the date of grant.

PROPOSED AMENDMENT

     Management recently reviewed the size of our existing automatic grants to
outside directors and decided that in order to maintain our ability to attract
and retain qualified members to our Board the grants must be increased.
Management presented to the Compensation Committee a recommendation to amend the
Plan to increase the amount of the initial grant of stock options from 10,000
shares to 40,000 shares and the amount of the annual grant of stock options from
2,000 shares to 40,000 shares. In addition, they proposed an additional annual
grant of an option to purchase 2,000 shares to each chairman of a committee of
the Board of Directors.  The Compensation Committee approved the amendments and
submitted them to the Board for approval in February 2001.  The Plan has been
amended, subject to stockholder approval.  All other terms of the automatic
grants remain the same.

     These amendments amend and restate the first sentences of Sections 7.1 and
7.2 of the Plan to read as follows:

     7.1  INITIAL GRANTS.  Each Outside Director who first becomes a member of
     the Board shall receive a one-time grant of an NQO covering 40,000 Common
     Shares (subject to adjustment under Article 9) (1).

     7.2  ANNUAL GRANTS.  Upon the conclusion of each regular annual meeting of
     the Company's stockholders, (i) each Outside Director who will continue
     serving as a member of the Board thereafter shall receive an NQO covering
     40,000 Common Shares, except that such NQO shall not be granted in the
     calendar year in which the same Outside Director received the NQO described
     in Section 7.1, and (ii) each director who will serve as chairman of a
     Board committee thereafter shall receive an NQO covering 2,000 Common
     Shares (both awards are subject to adjustment under Article 9).
     _________________
     (1)  Article 9 covers changes to the stock options as a result of a stock
     split, recapitalization, spin-off or similar occurrence.

REQUIRED APPROVAL

     The affirmative vote of the holders of a majority of our outstanding common
stock is required to approve this proposal.  Therefore, failure to vote will
have the same effect as a vote against the amendment.  If approved by the
stockholders, the proposed amendment to the 1997 Stock Incentive Plan will
become effective immediately.

PARTICIPATION IN THE 1997 STOCK INCENTIVE PLAN

     The grant of options under the 1997 Stock Incentive Plan to employees,
including the named executive officers, is subject to the discretion of the
Compensation Committee.  As of the date of this proxy statement, there has been
no determination by the Compensation Committee with respect to future awards
under the Plan.  Accordingly, future awards are not determinable.  The following
table sets forth information with respect to the grant of options to the named
executive officers and to other persons participating in the Plan during the
fiscal year 2000.

FEDERAL INCOME TAX CONSEQUENCES

     The following is a brief summary of the effect of federal income taxation
upon the participant and us under the Plan based upon the Internal Revenue Code.
This summary is not intended to be complete and does not discuss the income tax
laws of any municipality, state or country outside of the United States.  It is
advisable that a participant contact his or her own qualified tax advisor
concerning the application of tax laws.

     If an option granted under the Plan is an incentive stock option, the
optionee will recognize no taxable income upon grant or exercise of the
incentive stock option unless the alternative minimum tax rules apply.  Upon the
resale or exchange of the shares any gain (or loss) will be taxed to the
optionee as ordinary income (or loss) or capital gain (or loss), depending on
how long the optionee has held the stock.

     All options that do not qualify as incentive stock options are taxed as
non-qualified stock options.  An optionee will not recognize any taxable income
at the time of grant of a non-qualified stock option.  However, upon the
exercise of a non-qualified stock option, the optionee will generally recognize
ordinary income for federal income tax purposes measured by the excess, if any,
of the then fair market value of the shares over the exercise price.  The
ordinary income recognized upon exercise of a non-qualified stock option by an
optionee who is also one of our employees will be treated as wages for tax
purposes and will be subject to tax withholding out of the current compensation,
if any, paid to the optionee.  Upon resale of such shares by the optionee, any
difference between the sale price and fair market value on the date of exercise
will be treated as capital gain (or loss).

     We will be entitled to a tax deduction in the same amount as the ordinary
income, if any, recognized by the optionee (i) upon exercise of a non-qualified
stock option and (ii) upon the sale of shares acquired by exercise of an
incentive stock option in a disqualifying disposition.  We will not be allowed a

     THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE PROPOSAL TO AMEND THE 1997
STOCK INCENTIVE PLAN.


                STOCKHOLDER PROPOSALS FOR THE 2002 ANNUAL MEETING

     Proposals of stockholders submitted pursuant to Rule 14a-8 under the
Securities and Exchange Act of 1934, as amended and intended to be presented for
consideration at our 2002 Annual Meeting of Stockholders must be received by us
not later than November 30, 2001 in order to be considered for inclusion in our
proxy materials for that meeting.

     The Company's Bylaws also establish an advance notice procedure with
respect to certain stockholder proposals and director nominations.  In the event
a stockholder wishes to nominate a candidate for election as a director, or
wishes to propose any other matter for consideration at the Annual Meeting,
other than proposals to be included in the Proxy Statement, written notice of
such intent to make such nomination or propose such action must be given to the
Secretary of the Company pursuant to certain procedures set forth in the
Company's Bylaws, a copy of which is available upon request from the Secretary
of the Company.  These procedures provide, among other things, that such
shareholder's written notice of intent must be delivered to the Secretary of the
Company not less than 60 days nor more than 90 days prior to the scheduled
meeting date; unless less than 70 days prior notice or public disclosure of the
date of the meeting is given or made by the Company, in which event such notice
of intent must be received not later than the earlier (i) of the 10th day
following the date on which notice of the meeting was mailed or such public
disclosure made or (ii) two (2) days prior to the date of the scheduled meeting.
Any such notice must contain certain specified information concerning the
proposed matter and the stockholder submitting the proposed matter, all as set
forth in the Bylaws.  The chairman of the Annual Meeting may refuse to
acknowledge the nomination of any person or the request for such other action
not made in compliance with the foregoing procedures.  If the foregoing
procedures are not followed and such nomination or other request for action is
nonetheless permitted, the proxy holders appointed by the Company herein shall
have discretionary voting authority with respect to such matters at the Annual
Meeting.


                                  OTHER MATTERS

     We are not aware of any other business that will be presented at the Annual
Meeting.  If any other business is properly brought before the Annual Meeting,
it is intended that proxies will be voted in accordance with the judgment of the
persons voting the proxies.

     Whether or not you plan to attend the meeting, please vote by Internet or
mark, sign, date and promptly return the enclosed proxy card in the enclosed
envelope.  No postage is required for mailing in the United States.

                                        By Order of the Board of Directors.
