                        ANNUAL MEETING OF SHAREHOLDERS

                            TO BE HELD MAY 8, 2001


       This proxy statement is furnished to shareholders in connection with
  solicitation by the Board of Directors of Rentech, Inc. of proxies for
  use at the annual meeting of shareholders to be held at the Courtyard by
  Marriott, Cosmopolitan Room, 934 16th Street, Denver, Colorado, on
  Tuesday, May 8, 2001 at 9:00 a.m., local time, and at any adjournments or
  postponements of the meeting.

       Rentech anticipates that this proxy statement and the accompanying
  form of proxy will be first sent or given to shareholders on or about
  March 15, 2001.


                      VOTING SECURITIES AND VOTING RIGHTS

       Only shareholders of record at the close of business on March 2,
  2001 are entitled to vote at the annual meeting or any adjournments or
  postponements of the meeting.  On that date, 64,050,946 shares of common
  stock were outstanding.  Each share of common stock outstanding on that
  date entitles the holder to one vote on each matter submitted to a vote
  at the meeting.  Cumulative voting is not allowed.

       Shareholders may vote in person or by proxy at the annual meeting.
  All properly executed proxies received prior to the commencement of
  voting at the meeting, and which have not been revoked, will be voted in
  accordance with the directions given.  If no specific instructions are
  given for a matter to be voted upon, the proxy holders will vote the
  shares covered by proxies received by them  (i) FOR the election of the
  nominees to the Board of Directors,  (ii) FOR adoption of the 2001 Stock
  Option Plan, and  (iii) in accordance with the directors' recommendations
  on any other matters that may come before the meeting.

       A quorum for the transaction of business at the meeting requires the
  presence at the annual meeting, in person or by proxy, of the holders of
  a majority of the shares entitled to vote at the meeting.  If a quorum is
  present at the meeting, the two nominees for election as directors who






    
                                                           PAGE 6

  receive the greatest number of votes cast for the election of directors
  at the meeting will be elected directors.  Any other matters submitted to
  a vote of the shareholders will be approved if they receive the
  affirmative vote of the holders of a majority of shares present in person
  or by proxy and entitled to vote on the matter.  Abstentions from votes
  and "broker non-votes" (shares held by brokers or nominees which are
  voted on at least one matter but which are not voted on a particular
  matter because the broker or nominee does not have discretionary voting
  power with respect to that matter and has not received voting
  instructions from the beneficial owner of such shares) will be counted as
  present for purposes of determining whether a quorum is present at the
  annual meeting.  Abstentions will be treated as present and entitled to
  vote at the meeting.  Accordingly, abstentions  (i) will have no effect
  on the outcome of the election of directors, and  (ii) will have the same
  effect as a vote against all other matters presented to shareholders at
  the annual meeting.  Broker non-votes on a matter will not be considered
  present and entitled to vote on that matter, and accordingly,  (i) will
  have no effect on the outcome of a matter requiring the approval of the
  holders of a plurality or majority of the shares present, in person or by
  proxy, and entitled to vote at the annual meeting, and  (ii) will have
  the same effect as a vote against a matter requiring the approval of a
  majority of all shares outstanding and entitled to vote at the annual
  meeting.

       Without affecting any vote previously taken, any shareholder may
  revoke a proxy at any time before it is voted, either by delivering to
  the Secretary of Rentech a written notice of revocation or a properly
  signed proxy bearing a later date, or by voting in person at the annual
  meeting.  Attendance at the meeting will not in and of itself constitute
  a revocation of a proxy.

       Proxies will be solicited primarily by mail.  In addition, officers,
  directors and employees of Rentech may solicit proxies in person or by
  telephone and facsimile transmission, for which they will not receive
  additional compensation.  Rentech will pay the costs of soliciting and
  distributing proxies.  Rentech may engage third parties to assist in
  soliciting proxies.  If it does, Rentech would incur additional costs.


                                PROPOSAL NO. 1

                             ELECTION OF DIRECTORS

       Rentech's Board of Directors currently consists of six members.  The
  board is divided into three classes of two directors each.  The directors
  in each class are elected for three years and until the election and
  qualification of their successors.

       Ronald C. Butz and Douglas L. Sheeran have been nominated for
  reelection as Class I directors for a term of three years each.  The two
  nominees are presently members of the Board of Directors.  All other
  members of the Board of Directors will continue in office until the
  expiration of their respective terms at the 2002 or 2003 annual meeting
  of shareholders.




    
                                                           PAGE 7

       If the accompanying proxy card is properly signed and returned to
  Rentech at or prior to the annual meeting, it will be voted for the
  election of the nominees, unless contrary instructions are specified.
  Although the Board of Directors has no reason to believe that either of
  the nominees will decline or be unable to serve as a director, should
  that occur, the persons appointed as proxies in the accompanying proxy
  card intend to vote, unless the number of nominees or directors is
  reduced by the Board of Directors, for such other nominee or nominees as
  the Board of Directors may designate.  The Board of Directors recommends
  a vote FOR these two nominees.

                                PROPOSAL NO. 2

                  ADOPTION OF THE 2001 STOCK OPTION PLAN

       The stockholders are asked to consider and vote upon a proposal to
  approve the 2001 Stock Option Plan (2001 Plan) which was adopted by the
  Board of Directors on January 16, 2001 subject to shareholder approval.
  The primary provisions of the 2001 Plan are described in the following
  paragraphs.

       The Board of Directors believes that the 2001 Plan will help
  attract, retain and motivate Rentech's key employees, directors and
  consultants, as well as achieve the goal of aligning management and
  shareholder interests, and is therefore in the company's best interests.

       Adoption of the 2001 Stock Option Plan requires the affirmative vote
  of at least a majority of the shares voting on such matter.  The Board of
  Directors recommends that you vote FOR the adoption of the 2001 Plan.

  Summary of the 2001 Plan:

       Shares Subject to the 2001 Plan.  The aggregate number of shares of
  Rentech's common stock that may be issued to grantees under the 2001 Plan
  is 500,000 shares.  The 2001 Plan provides for appropriate adjustment in
  the number of shares subject to the 2001 Plan and to the grants
  previously made if there is a stock split, stock dividend, reorganization
  or other relevant change affecting Rentech's corporate structure or its
  equity securities.  If shares under a grant are not issued to the extent
  permitted prior to the expiration or forfeiture of the grant, then those
  shares would again be available for inclusion in future grants.  No grant
  shall be made under the 2001 Plan after January 16, 2010, but awards
  granted prior to or on that date may extend beyond that time.

       Administration.  The 2001 Plan is administered by the stock option
  committee, the members of which meet the SEC definition of "disinterested
  directors" and the IRS definition of "outside directors."  The stock
  option committee selects the participants, grants awards of stock
  options, establishes rules and regulations for the operation of the 2001
  Plan and determines option terms, vesting schedules and number of shares
  subject to grants.  With respect to any awards granted, other than those





    
                                                           PAGE 13

  to executive officers and anyone else subject to Section 16 of the
  Securities Exchange Act of 1934, the stock option committee may delegate
  to the Chief Executive Officer its authority to select the participants
  and determine option terms, vesting schedules and number of shares
  subject to each grant.

       Eligible Participants.  All employees are considered responsible for
  contributing to the management, growth and profitability of the business
  of Rentech, and all employees, directors, and consultants are eligible to
  be selected to receive grants under the 2001 Plan.  As of December 31,
  2000 there were approximately 65 employees, two of whom are employee-
  directors and six directors who are eligible to receive stock option
  grants.

       Stock Options.  Options granted under the 2001 Plan will be in the
  form of either incentive stock options (ISOs), which meet the
  requirements of Section 422 of the Internal Revenue Code (the Code), or
  nonqualified stock options (NSOs), which do not meet such requirements.
  Only employees may receive ISOs.  The term of an option will be fixed by
  the stock option committee, but no option may have a term of more than
  ten years from the date of grant.  Options will be exercisable at such
  times as determined by the stock option committee.  The option exercise
  price is fair market value on the date of grant which is determined by
  the average of the closing bid and asked prices of a share of common
  stock on the date of grant if the date of grant is a trading date, or, if
  not, on the most recently completed trading date prior to the date of
  grant, as reported by Nasdaq.  (On January 16, 2001, the closing sale
  price of a share of common stock was $1.188).  The date of grant is the
  date on which the stock option committee grants an award or such other
  date as the stock option committee may designate at the time of the
  award.  The grantee will pay the option price in cash or, if permitted by
  the stock option committee, by delivering to the Company shares of common
  stock already owned by the grantee that have a fair market value equal to
  the option exercise price.

       Code Limitations on Incentive Stock Options.  The Code currently
  places the following limitations on the award of ISOs.  No ISO may be
  granted to a participant who owns, at the date of grant, in excess of 10%
  of the total outstanding common stock unless the exercise price of the
  ISO is at least 110% of the fair market value on the date of grant and
  the term of the ISO is no more than five years from the date of grant.
  The total fair market value of shares subject to ISOs which are
  exercisable for the first time by any optionee in any given calendar year
  cannot exceed $100,000 (valued as of the date of grant).  No ISO may be
  exercisable more than three months following termination of employment
  for any reason other than death or disability, nor more than one year
  with respect to disability terminations.

       Transferability of Awards.  All stock options are non-transferable
  and may be exercised during the grantee's lifetime only by the grantee
  and may not be transferred other than by will or by the laws of descent
  and distribution.  No award of an option may be assigned, pledged,
  hypothecated or otherwise alienated or encumbered (whether by operation
  of law or otherwise), and any attempt to do so shall be null and void.





    
                                                           PAGE 14

  ISOs will be non-transferable in accordance with the provisions of the
  Code.

       Termination of Employment.  Vested options can be exercised for a
  period no longer than one year after the death or disability of the
  grantee.  Unless an earlier date is fixed by the stock option committee
  at the time of grant, unvested portions of stock options immediately
  expire upon termination of employment for any other reason, but vested
  portions of the options may be exercised for up to three months following
  the termination, unless termination is for cause.  If the Company
  terminates employment for cause, all unexercised awards expire upon the
  termination.  Termination of employment by a participant will not be
  deemed to occur upon:  (i) transfer of a participant among the Company
  and its subsidiaries; and  (ii) a leave of absence for a company-approved
  purpose.  Termination of ISOs will be in accordance with the provisions
  of the Code.

       Conditions Upon Exercise of Stock Options.  Shares of stock may not
  be issued or delivered upon exercise of a stock option until the optionee
  pays in full the exercise price and any required tax withholding and, if
  applicable, the completion of registration and listing of the shares or
  qualification as a private placement and the obtaining of any other
  required approvals.

       Federal Tax Consequences.  There are no Federal income tax
  consequences to a participant or Rentech upon the grant of an ISO or NSO.
  Otherwise, however, ISOs and NSOs are treated differently for income tax
  purposes.

       An optionee is not taxed on the grant or exercise of an ISO.  The
  difference between the exercise price and the fair market value of the
  shares on the exercise date will, however, be a preference item for
  purposes of the alternative minimum tax.  If an optionee holds the shares
  acquired upon exercise of an ISO for at least two years following grant
  and at least one year following exercise, the optionee's gain, if any,
  upon a subsequent disposition of such shares is long-term capital gain.
  The measure of the gain is the difference between the proceeds received
  on disposition and the optionee's basis in the shares (which generally
  equals the exercise price).  If an optionee disposes of stock acquired
  pursuant to exercise of an ISO before satisfying the one and two-year
  holding periods previously described, the optionee will recognize both
  ordinary income and capital gain in the year of disposition.  The amount
  of the ordinary income will be the lesser of:  (i) the amount realized on
  disposition less the optionee's adjusted basis in the stock (usually the
  exercise price), or  (ii) the difference between the fair market value of
  the stock on the exercise date and the exercise price.  The balance of
  the consideration received on such a disposition will be long-term
  capital gain if the stock had been held for at least one year following
  exercise of the ISO.  The Company is not entitled to an income tax
  deduction on the grant or exercise of an ISO or on the optionee's
  disposition of the shares after satisfying the holding period
  requirements previously described.  If the holding periods are not
  satisfied, the Company will be entitled to a deduction in the year the
  optionee disposes of the shares, in an amount equal to the ordinary
  income recognized by the optionee.



    
                                                           PAGE 15

       An optionee is not taxed on the grant of an NSO.  On exercise,
  however, the optionee recognizes ordinary income equal to the difference
  between the exercise price and the fair market value of the shares on the
  date of exercise.  Rentech is entitled to an income tax deduction in the
  year of exercise in the amount recognized by the optionee as ordinary
  income.  Any gain or subsequent disposition of the shares is long-term
  capital gain if the shares are held for at least one year following
  exercise.  Rentech does not receive a deduction for this gain.

       Amendments and Discontinuance.  The Board of Directors may amend,
  alter or discontinue the 2001 Plan, provided that any such amendment,
  alteration or discontinuance does not impair the rights of any grantee,
  without his or her consent, under any stock option previously granted.
  The Board of Directors may not, without shareholder approval,  (i)
  increase the total number of shares reserved for issuance under the 2001
  Plan,  (ii) change the employees or class of employees eligible to
  participate in the 2001 Plan, or  (iii) extend the maximum option period
  as provided in the 2001 Plan.

              MEETINGS AND COMMITTEES OF THE BOARD OF DIRECTORS

       The Board of Directors held two meetings and acted by written
  consent five other times during the fiscal year ended September 30, 2000.
  No director attended fewer than 75% of the meetings of the Board of
  Directors held during the period for which he has been a director or of
  the meetings of committees of the Board of Directors on which he served
  during the period that he served.  Directors who are not employees of
  Rentech are not paid fees for their services.  Instead, they have been
  granted stock options as consideration.

       The Board of Directors has a standing audit committee, a stock
  option committee and a compensation committee.  It has no standing
  nominating committees.

       The audit committee of the Board of Directors reports to the board
  regarding the appointment of the Company's independent public
  accountants, the scope and results of its annual audits, compliance with
  accounting and financial policies and management's procedures and
  policies relative to the adequacy of internal accounting controls.





    
                                                           PAGE 17

  During fiscal 2000, the audit committee consisted of Mr. Ball, Mr. Diesel
  and Dr. Tiepel, all of whom are independent directors of the Company as
  defined by the listing standards of the American Stock Exchange.  During
  fiscal 2000, the audit committee met three times.  The charter adopted by
  the Board of Directors for the audit committee is attached as Appendix A
  to this proxy statement.

       The stock option committee currently consists of Dr. Erich W. Tiepel
  and Douglas L. Sheeran.  The committee formally met two times during the
  fiscal year ended September 30, 2000, and also met informally several
  other times.  The function of the committee is to determine the grant of
  stock options to the executive officers and the terms of any options
  granted to them.  The committee made no grants of stock options to the
  Company's executive officers during fiscal year 2000.

       The compensation committee is comprised of Messrs. John J. Ball,
  John P. Diesel, Douglas L. Sheeran and Dr. Erich W. Tiepel.  None of
  these directors have ever served as officers of the Company.  The
  committee met three times during the last fiscal year.


                            EXECUTIVE COMPENSATION

  Employment Contracts

       Executive officers generally are elected at the annual director
  meeting immediately following the annual stockholder meeting.  Any
  officer or agent elected or appointed by the Board of Directors may be
  removed by the board whenever in its judgment our best interests will be
  served thereby, without prejudice to contractual rights, if any, of the
  person so removed.

       Rentech employs Messrs. Benham, Bohn, Butz, Samuels and Yakobson
  pursuant to employment contracts that extend for three years.  Mr.
  Livingston and Mr. Fletcher are employed according to contracts that
  extend to December 31, 2001.

       The contracts provide that the individuals will serve in their
  present capacities as officers, together with such duties,
  responsibilities and powers as the Board of Directors may reasonably
  specify.  The contracts provide for annual cost of living adjustments.
  If Rentech terminates employment early without cause, the contracts
  provide for payment of salary for three years as severance pay.  The
  contracts impose obligations of confidentiality as well as covenants not
  to compete with Rentech following termination of employment for any
  reason whatsoever.

       There are no family relationships among the executive officers.
  There are no arrangements or understandings between any officer and any
  other person pursuant to which that officer was elected.

  Compensation Committee Report on Executive Compensation

       The compensation committee establishes the base salaries and any
  cash bonuses paid to the Company's executive officers.  It is the policy
  of the committee to position the base salaries of Rentech's executives at
  levels comparable to those provided to executives of other companies it
  deems comparable.  These include companies engaged in development of new
  technologies.  The policy is designed to link  each executive's
  compensation to individual performance and the Company's achievement of
  its goals.

       The compensation committee annually reviews the base salary of each
  of the executive officers of the Company, including Mr. Yakobson, the
  Chief Executive Officer.  In determining salary adjustments, the
  committee considers several factors.  These include individual job
  performance, responsibility, financial and operational performance of the
  activities directed by the executive, experience, time in position,
  future potential, and salary levels of comparable companies.  The factors
  are considered subjectively in the aggregate, and none of the factors is
  accorded a specific weight.  The committee has also reviewed information
  on the compensation levels of executive officers provided by three annual
  compensation surveys compiled by independent third parties.  The surveys
  covered approximately 1,500 small to medium size companies.  Two of the
  surveys applied to companies doing business at locations around the
  United States, and one included only companies located in the Rocky
  Mountain states.  The committee used all of this information to arrive at
  total compensation for the Company's executive officers that it believes
  is appropriate to the Company's performance and their individual
  contributions.




    
                                                           PAGE 20

       During the fiscal year ended September 30, 2000, the compensation
  committee supplemented the salaries of its executives with cash bonuses.
  The bonuses were awarded by the committee, taking into consideration its
  financial condition at the time, to compensate for previous salaries that
  the committee determined had been inadequate.  No particular formula was
  used in determining the amount of the bonuses.  The amounts awarded as
  bonuses to individual executives, including the Chief Executive Officer,
  reflect the committee's assessment of the executive's performance, level
  of responsibility, compensation received by executives in similar
  companies, previous compensation paid by Rentech to the same executives,
  and Rentech's financial position.


                         REPORT OF THE AUDIT COMMITTEE

       We have reviewed and discussed the audited financial statements of
  Rentech for fiscal year 2000 with management.  We have also discussed the
  audited financial statements with Rentech's independent auditors.  Our
  discussions with the independent auditors included, among other things,
  discussions relating to the auditor's responsibility under generally
  accepted auditing standards, the processes used by our management in
  formulating accounting estimates, significant adjustments made during the
  audit, any disagreements with our management and any difficulties
  encountered by the independent auditors in performing the audit.  We also
  reviewed written disclosures from the independent auditors relating to
  any and all relationships between them and Rentech, and we discussed with
  the auditors any relationship that might affect the objectivity or
  independence of the independent auditors.  Based on those discussions, we
  are not aware of any relationship between the independent auditors and
  Rentech that affects the objectivity or independence of the independent
  auditors.

       Based on the discussions and our review discussed above, we
  recommended to the Board of Directors that the audited financial
  statements for fiscal year 2000 be included in Rentech's Annual Report on
  Form 10-K for 2000 for filing with the SEC.

       This report is submitted by the members of the audit committee.

                                      John J. Ball
                                      John P. Diesel
                                      Erich W. Tiepel

       In accordance with the rules and regulations of the SEC, neither the
  report of the audit committee, the compensation committee, nor the
  performance graph appearing below will not be deemed to be "soliciting
  material" or to be "filed" with the SEC or subject to Regulations 14A or
  14C of the Securities Exchange Act of 1934 or to the liabilities of
  Section 18 of the Exchange Act and will not be deemed to be incorporated
  by reference into any filing under the Securities Act of 1933 or the
  Exchange Act, notwithstanding any general incorporation by reference of
  this proxy statement into any other filed document.

  Stock Performance Chart

       The following chart compares the yearly percentage change in the
  cumulative shareholder return on our common stock from October 1995 to
  the end of the fiscal year ended September 30, 2000 with the cumulative
  total return on the American Major Market Index and the Dow Jones
  Oilfield Equipment & Services Index, a published line-of-business index.
  The comparison assumes $100 was invested on September 30, 1995 in our
  common stock and in each of the foregoing indices and assumes dividends,
  if any, were reinvested.

                  SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING

       Rentech's executive officers and directors are required to file
  reports of ownership and changes in ownership of Rentech's securities
  with the Securities and Exchange Commission as required under provisions
  of Section 16(a) of the Securities Exchange Act of 1934.  Based solely on
  the information provided to Rentech by individual directors and executive
  officers, Rentech believes that during the last fiscal year all directors
  and executive officers have complied with the applicable filing
  requirements.


                   INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

       The Board of Directors has selected BDO Seidman, LLP as the
  independent certified public accountants to audit the books, records and
  accounts of Rentech for its 2001 fiscal year.  To the knowledge of
  management, neither such firm nor any of its members has any direct or
  material indirect financial interest in Rentech nor any connection with
  Rentech in any capacity otherwise than as independent accountants.

       A representative of BDO Seidman, LLP is expected to be present at
  the annual meeting of shareholders to answer proper questions and will be
  afforded an opportunity to make a statement regarding the financial
  statements.




    
                                                           PAGE 22

                            SERVICES PERFORMED BY THE COMPANY'S AUDITORS

       Audit Fees.  For the year ended September 30, 2000, the Company
  incurred professional fees and out-of-pocket expenses to its auditors in
  the amount of $131,000 related to auditing services.

       All Other Fees.  The Company was billed $68,000 by its auditors for
  all other services provided during fiscal year 2000.

       The Company's audit committee has considered whether the non-audit
  services provided by the Company's auditors in connection with the year
  ended September 30, 2000 were compatible with the auditors' independence.


                             SHAREHOLDER PROPOSALS

       Proposals of shareholders intended to be presented at the annual
  meeting of shareholders held in 2002 must be received by Rentech's
  corporate secretary on or before November 4, 2001, in order to be
  eligible for inclusion in Rentech's proxy statement and form of proxy.
  To be included, a proposal must also comply with all applicable
  provisions of Rule 14a-8 under the Securities Exchange Act of 1934.


                                 OTHER BUSINESS

       Management does not know of any other matters to be brought before
  the annual meeting.  If any other business items not mentioned in this
  proxy statement are properly brought before the meeting, the individuals
  named in the enclosed proxy intend to vote such proxy in accordance with

                           AUDIT COMMITTEE CHARTER

  Organization

       There shall be a permanent committee of the Board of Directors known
  as the Audit Committee (the Committee).  The Committee shall be composed
  of three or more directors, each of whom is independent of the management
  of the Company and free of any relationship that, in the opinion of the
  Board of Directors, would interfere with the exercise of independent
  judgment as a member of the Committee.  The members of the Committee
  shall be appointed by the Board of Directors and shall serve until each
  annual meeting of the stockholders of the Company or until their
  successors are elected or appointed.  Each member of the Committee shall
  have knowledge of financial matters, or shall obtain knowledge of
  financial matters within a reasonable time after his appointment to the
  Committee and at least one member of the Committee shall have accounting
  or related financial management expertise.

  Statement of Policy

       The Committee shall provide assistance to the corporate directors in
  fulfilling their responsibility to the shareholders, relating to
  corporate accounting and reporting practices of the Company and the
  quality and integrity of the financial reports of the Company.  In so
  doing, it is the responsibility of the Committee to maintain free and
  open means of communication between the directors, the independent
  auditors, the internal auditors and the financial management of the
  Company.

  Responsibilities

       In carrying out its responsibilities, the Committee believes its
  policies and procedures should remain flexible, to best react to changing
  conditions and to ensure to the Board of Directors and shareholders that
  the corporate accounting and reporting practices of the Company are in
  accordance with all requirements and are of the highest quality.

       In carrying out these responsibilities, the Committee will:

       1.  Review and recommend to the directors the independent auditors
  to be selected to audit the financial statements of the Company and its
  divisions and subsidiaries.

       2.  Have a clear understanding with the independent auditors that
  they are ultimately accountable to the Board of Directors and the
  Committee, as the shareholders' representatives, who collectively have
  the ultimate authority in deciding to engage, evaluate, and if
  appropriate, terminate their services.

       3.  Review with the independent auditors and financial management of
  the Company the scope of the proposed audit and timely quarterly reviews
  for the current year and of non-audit services requested and the
  procedures to be utilized.



    
                                                           PAGE 24

       4.  Ensure receipt from the Company's outside auditors of a formal,
  written statement delineating all relationships between the auditors and
  the Company, and discuss with the auditors any disclosed relationships or
  services that may affect objectivity or independence and take appropriate
  action to ensure the continued independence of the auditors.

       5.   Review with the auditors and management the Company's
  policies and procedures with respect to internal auditing, accounting and
  financial control procedures.

                           ESTABLISHMENT AND PURPOSE

       1.1  Establishment.  Rentech, Inc., a Colorado corporation
  ("Company"), hereby establishes a stock option plan for key employees,
  directors, and consultants providing material services to the Company, as
  described herein, which shall be known as the "2001 Stock Option Plan"
  (the "Plan").  It is intended that certain of the options issued to
  employees pursuant to the Plan may constitute incentive stock options
  within the meaning of Section 422A of the Internal Revenue Code and that
  other options issued pursuant to the Plan shall constitute nonstatutory
  options.  The Board of Directors shall determine which options are to be
  incentive stock options and which are to be nonstatutory options and
  shall enter into option agreements with recipients accordingly.

       1.2  Purpose.  The purpose of this Plan is to enhance shareholder
  investment by attracting, retaining and motivating key employees,
  directors and consultants of the Company, and to encourage stock
  ownership by such persons by providing them with a means to acquire a
  proprietary interest in the Company's success, and to align the interests
  of management with those of shareholders.

                                  ARTICLE III
                         ELIGIBILITY AND PARTICIPATION

       3.1  Eligibility and Participation.  All Employees are eligible to
  participate in this Plan and receive either or both Incentive Stock
  Options and Nonstatutory Options under the Plan.  All Consultants are
  eligible to participate in this Plan and receive Nonstatutory Options
  hereunder.  Optionees in the Plan shall be selected by the Board, in its
  sole discretion, from among those Employees and Consultants who, in the
  opinion of the Board, are in a position to contribute materially to the
  Company's continued growth and development and to its long-term financial
  success.

                                 ARTICLE IV
                               ADMINISTRATION

       4.1  Administration.  The Board shall be responsible for
  administering the Plan.

            (a)  The Board is authorized to interpret the Plan; to
  prescribe, amend, and rescind rules and regulations relating to the Plan;
  to provide for conditions and assurances deemed necessary or advisable to
  protect the interests of the Company; and to make all other
  determinations necessary or advisable for the administration of the Plan.
  Determinations, interpretations, or other actions made or taken by the
  Board, pursuant to the provisions of this Plan, shall be final and
  binding and conclusive for all purposes and upon all persons.

            (b)  At the discretion of the Board this Plan may be
  administered by a Committee which shall be an executive committee of the
  Board, consisting of not less than two members of the Board.  The members
  of such Committee may be directors who are eligible to receive Options
  under this Plan, but Options may be granted to such persons only by
  action of the full Board and not by action of the Committee.  If the
  Company determines that grant of Options by the full Board to members of
  the Committee may not exempt the shares of Committee members from the
  provisions of Rule 16b-3 under the Securities Exchange Act of 1934, this
  Plan, without further action, hereby authorizes and grants options to
  purchase 10,000 shares each to each member of the Committee for each year




    
                                                           PAGE 30

  of continuous service on the Committee, except that, (i) any Committee
  member, for any year, may elect not to accept an option to purchase
  10,000 shares or may elect to accept options for the purchase of less
  than 10,000 shares; and (ii) if any Committee member elects, for any
  year, to receive no option or an option to purchase less than 10,000
  shares for that year, that option shall be deemed permanently waived,
  shall not cumulate, and shall not be available in any future year.  Such
  options shall be exercisable at the fair market value of the Stock on the
  date of grant and shall have the same term and may be exercised in
  installments as provided in Section 7.3 of this Plan.  Such Committee
  shall have full power and authority, subject to the limitations of the
  Plan and any limitations imposed by the Board, to construe, interpret and
  administer this Plan and to make determinations which shall be final,
  conclusive and binding upon all persons, including, without limitation,
  the Company, the shareholders, the directors and any persons having any
  interests in any Options which may be granted under this Plan, and, by
  resolution or resolutions providing for the creation and issuance of any
  such Option, to fix the terms upon which, the time or times at or within
  which, and the price or prices at which any such shares may be purchased
  from the Company upon the exercise of such Option.  Such terms, time or
  times and price or prices shall, in every case, be consistent with the
  provisions of this Plan, and shall be set forth or incorporated by
  reference in the instrument or instruments evidencing such Option.

            (c)  If the Committee has been appointed, the Board may from
  time to time remove members from, or add members to, the Committee.  The
  Board may terminate the Committee at any time.  Vacancies on the
  Committee, howsoever caused, shall be filled by the Board.  The Committee
  shall select one of its members as Chairman, and shall hold meetings at
  such times and places as the Chairman may determine.  A majority of the
  Committee at which a quorum is present, or acts reduced to or approved in
  writing by all of the members of the Committee, shall be the valid acts
  of the Committee.  A quorum shall consist of a majority of the members of
  the Committee.

            (d)  Where the Committee has been created by the Board,
  references in this Plan to actions to be taken by the Board shall be
  deemed to refer to the Committee as well, except where limited by this
  Plan or by the Board.

              (e)  The Board shall have all of the enumerated powers of the
  Committee, but shall not be limited to such powers.  No member of the
  Board or the Committee shall be liable for any action or determination
  made in good faith with respect to the Plan or any Option granted under
  it.

         4.2  Special Provisions for Grants to Officers or Directors.  Rule
  16b-3 under the Securities and Exchange Act of 1934 (the "Act") provides
  that the grant of a stock option to a director or officer of a company
  subject to the Act will be exempt from the provisions of Section 16(b) of
  the Act if the conditions set forth in said Rule are satisfied.  Unless
  otherwise specified by the Board, grants of Options hereunder to
  individuals who are officers or directors of the Company shall be made in
  a manner that satisfies the conditions of said Rule.



    
                                                           PAGE 31

                                  ARTICLE V
                           STOCK SUBJECT TO THE PLAN

       5.1  Number.  The total number of shares of Stock hereby made
  available and reserved for issuance under the Plan shall be 500,000
  shares for Incentive Stock Options and Nonstatutory Stock Options.  The
  aggregate number of shares of Stock available under this Plan shall be
  subject to adjustment as provided in Section 5.3.  The total number of
  shares of Stock may be authorized but unissued shares of Stock, or Shares
  acquired by purchase as directed by the Board from time to time in its
  discretion, to be used for issuance upon exercise of Options granted
  hereunder.

       5.2  Unused Stock.  If an Option shall expire or terminate for any
  reason without having been exercised in full, the unpurchased shares of
  Stock subject thereto shall (unless the Plan shall have terminated)
  become available for other Options under the Plan.

       5.3  Adjustment in Capitalization.  In the event of any change in
  the outstanding shares of Stock by reason of a stock dividend or split,
  recapitalization, reclassification, or other similar corporate change,
  the aggregate number of shares of Stock remaining subject to the Plan and
  to Options previously granted shall be appropriately adjusted by the
  Board, whose determination shall be conclusive; provided however, that
  fractional shares shall be rounded to the nearest whole share.  In any
  such case, the number and kind of shares that are subject to any Option
  (including any Option outstanding after termination of employment) and
  the Option price per share shall be proportionately and appropriately
  adjusted without any change in the aggregate Option price to be paid
  therefor upon exercise of the Option.

                                  ARTICLE VI
                              DURATION OF THE PLAN

       6.1  Duration of the Plan.  Subject to approval of shareholders, the
  Plan shall be in effect for ten years from the date of its adoption by
  the Board.  Any Options outstanding at the end of said period shall
  remain in effect in accordance with their terms.  The Plan shall
  terminate before the end of said period if all Stock subject to it has
  been purchased pursuant to the exercise of Options granted under the
  Plan.

                                  ARTICLE VII
                            TERMS OF STOCK OPTIONS

       7.1  Grant of Options.  Subject to Section 5.1, Options may be
  granted to Employees or Consultants at any time and from time to time as
  determined by the Board; provided, however, that Consultants may receive
  only Nonstatutory Options and may not receive Incentive Stock Options.
  The Board shall have complete discretion in determining the terms and
  conditions and number of Options granted to each Optionee.  In making
  such determinations, the Board may take into account the nature of
  services rendered by such Employees or Consultants, their present and






    
                                                           PAGE 32


  potential contributions to the Company and its Subsidiary Corporations,
  and such other factors as the Board in its discretion shall deem
  relevant.  The Board also shall determine whether an Option is to be an
  Incentive Stock Option or a Nonstatutory Option.

            (a)  In the case of Incentive Stock Options, the total Fair
  Market Value (determined at the date of grant) of shares of Stock with
  respect to which incentive stock options granted after December 31, 1986
  are exercisable for the first time by the Optionee during any calendar
  year under all plans of the Company under which incentive stock options
  may be granted (and all such plans of any Parent Corporations and any
  Subsidiary Corporations of the Company) shall not exceed $100,000.
  Hereinafter, this requirement is sometimes referred to as the "$100,000
  Limitation".

            (b)  Nothing in this Article VII of the Plan shall be deemed to
  prevent the grant of Options permitting exercise in excess of the
  maximums established by the preceding paragraph where such excess amount
  is treated as a Nonstatutory Option.

            (c)  The Board is expressly given the authority to issue
  amended or replacement Options with respect to shares of Stock subject to
  an Option previously granted hereunder.  An amended Option amends the
  terms of an Option previously granted and thereby supersedes the previous
  Option.  A replacement Option is similar to a new Option granted
  hereunder except that it provides that it shall be forfeited to the
  extent that a previously granted Option is exercised, or except that its
  issuance is conditioned upon the termination of a previously granted
  Option.

            (d)  The date of grant of an Option is either the date it is
  granted or such other date as may be designed at the time of the award of
  the Option.

       7.2  No Tandem Options.  Where an Option granted under this Plan is
  intended to be an Incentive Stock Option, the Option shall not contain
  terms pursuant to which the exercise of the Option would affect the
  Optionee's right to exercise another Option, or vice versa, such that the
  Option intended to be an Incentive Stock Option would be deemed a tandem
  stock option within the meaning of the regulations under Section 422A of
  the Code.

       7.3  Option Agreement: Terms and Conditions to Apply Unless
  Otherwise Specified.  As determined by the Board on the date of grant,
  each Option shall be evidenced by an Option agreement (the "Option
  Agreement") that includes the non-transferability provisions required by
  Section 10.2 hereof and specifies: whether the Option is an Incentive
  Stock Option or a Nonstatutory option; the Option price; the duration of
  the Option; the number of shares of Stock to which the Option applies;
  any vesting or exercisability restrictions which the Board may impose; in
  the case of an Incentive Stock Option, a provision implementing the
  $100,000 Limitation; and any other terms or conditions which the Board
  may impose.  All such terms and conditions shall be determined by the
  Board at the time of grant of the Option.




    
                                                           PAGE 33

            (a)  If not otherwise specified by the Board, the following
  terms and conditions shall apply to Options granted under the Plan:

                 (i)  Term.  The duration of the Option shall be five years
  from the date of grant.

                 (ii)  Exercise of Option.  Unless an Option is terminated
  as provided hereunder, an Optionee may exercise his Option for up to, but
  not in excess of, the amounts of shares subject to the Option specified
  hereafter in this section, based on the Optionee's number of years of
  continuous service with the Company or a Subsidiary Corporation from the
  date on which the Option is granted.  In the case of an Optionee who is
  an Employee, continuous service shall mean continuous employment; in the
  case of an Optionee who is a Consultant, continuous service shall mean
  the continuous provision of consulting services.  In applying said
  limitations, the amount of shares, if any, previously purchased by the
  Optionee under the Option shall be counted in determining the amount of
  shares the Optionee can purchase at any time.  The Optionee may exercise
  his Option in the following amounts:

                          (A)  After one year of such continuous services,
  up to but not in excess of twenty percent of the shares originally
  subject to the Option;

                          (B)  After two years of such continuous services,
  up to but not in excess of forty percent of the shares originally subject
  to the Option;

                          (C)  After three years of such continuous
  services, up to but not in excess of sixty percent of the shares
  originally subject to the Option;

                          (D)  After four years of such continuous
  services, up to but not in excess of eighty percent of the shares
  originally subject to the Option; and

                          (E)  At the expiration of the fifth year of such
  continuous services, the Option may be exercised, in whole or in part,
  and at any time and from time to time within its term but it shall not be
  exercisable after the expiration of five years from the date on which it
  was granted.

                  (b)  The Board shall be free to specify terms and
  conditions other than those set forth above, in its discretion.

                  (c)  All Option Agreements shall incorporate the
  provisions of this Plan by reference, with certain provisions to apply
  depending upon whether the Option Agreement applies to an Incentive Stock
  Option or to a Nonstatutory Option.

       7.4  Option Price.  No Incentive Stock Option granted pursuant to
  this Plan shall have an Option price that is less than the Fair Market
  Value of Stock on the date the Option is granted.  Incentive Stock
  Options granted to Significant Shareholders shall have an Option price of





    
                                                           PAGE 34

  not less than 110 percent of the Fair Market Value of Stock on the date
  of grant.  The Option price for Nonstatutory Options shall be established
  by the Board and shall not be subject to the restrictions applicable to
  Incentive Stock Options.

       7.5  Term of Options.  Each Option shall expire at such time as the
  Board shall determine when it is granted, provided however that under no
  circumstances shall a Nonstatutory Option be exercisable later than the
  tenth anniversary date of its grant, nor by its terms, shall an Incentive
  Stock Option granted to a Significant Shareholder be exercisable later
  than the fifth year from the anniversary date of its grant.

       7.6  Exercise of Options.  Options granted under the Plan shall be
  exercisable at such times and be subject to such restrictions and
  conditions as the Board shall in each instance approve, which need not be
  the same for all Optionees.

       7.7  Payment.  Payment for all shares of Stock shall be made at the
  time that an Option, or any part thereof, is exercised, and no shares
  shall be issued until full payment has been made.  Payment shall be made
  (i) in cash, or (ii) if acceptable to the Board, in Stock or in some
  other form; provided, however, in the case of an Incentive Stock Option,
  that said other form of payment does not prevent the Option from
  qualifying for treatment as an incentive stock option within the meaning
  of the Code.

                                  ARTICLE VIII
                      WRITTEN NOTICE, ISSUANCE OF STOCK
                     CERTIFICATES; SHAREHOLDER PRIVILEGES

       8.1  Written Notice.  An Optionee wishing to exercise an Option
  shall give written notice to the Company, in the form and manner
  prescribed by the Board.  Full payment for the shares exercised pursuant
  to the Option must accompany the written notice.

       8.2  Issuance of Stock Certificates.  As soon as practicable after
  the receipt of written notice and payment, the Company shall deliver to
  the Optionee or to a permitted nominee of the Optionee a certificate or
  certificates for the requisite number of shares of stock.

       8.3  Privileges of a Shareholder.  An Optionee or any other person
  entitled to exercise an Option under this Plan shall not have stockholder
  privileges with respect to any Stock covered by the Option until the date
  of issuance of a stock certificate for such stock.

                                  ARTICLE IX
                     TERMINATION OF EMPLOYMENT OR SERVICES

       9.1  Death.  If an Optionee's employment in the case of an Employee,
  or provision of services as a Consultant, in the case of a Consultant,
  terminates by reason of death, the Option may thereafter be exercised at
  any time prior to the expiration date of the Option or within 12 months
  after the date of such death, whichever period is the shorter, by the
  person or persons entitled to do so under the Optionee's will or, if the





    
                                                           PAGE 35

  Optionee shall fail to make a testamentary disposition of an Option or
  shall die intestate, the Optionee's legal representative or
  representatives.  The Option shall be exercisable only to the extent that
  such Option was exercisable as of the date of death.

       9.2  Termination other than for Cause or Due to Death.  In the event
  of an Optionee's termination of employment, in the case of an Employee,
  or termination of the provision of services as a Consultant, in the case
  of a Consultant, other than by reason of death, the Optionee may exercise
  such portion of his Option as was exercisable by him at the date of such
  termination (the "Termination Date") at any time within three months of
  the Termination Date; provided, however, that where the Optionee is an
  Employee, and is terminated due to disability within the meaning of Code
  422A, he may exercise such portion of his Option as was exercisable by
  him on his Termination Date within one year of his Termination Date.  In
  any event, the Option cannot be exercised after the expiration of the
  term of the Option.  Options not exercised within the applicable period
  specified above shall terminate.

            (a)  In the case of an Employee, a change of duties or position
  within the Company or an assignment of employment in a Subsidiary
  Corporation or Parent Corporation of the Company, if any, or from such a
  Corporation to the Company, shall not be considered a termination of
  employment for purposes of this Plan.

            (b)  The Option Agreements may contain such provisions as the
  Board shall approve with reference to the effect of approved leaves of
  absence upon termination of employment.

       9.3  Termination for Cause.  In the event of an Optionee's
  termination of employment, in the case of an Employee, or termination of
  the provision of services as a Consultant, in the case of a Consultant,
  which termination is by the Company or a Subsidiary Corporation for
  cause, any Option or Options held by him under the Plan, to the extent
  not exercised before such termination, shall terminate upon notice of
  termination for cause.

                                   ARTICLE X
                              RIGHTS OF OPTIONEES

       10.1  Service.  Nothing in this Plan shall interfere with or limit
  in any way the right of the Company or a Subsidiary Corporation to
  terminate any Employee's employment, or any Consultant's services, at any
  time, nor confer upon any Employee any right to continue in the employ of
  the Company or a Subsidiary Corporation, or upon any Consultant any right
  to continue to provide services to the Company or a Subsidiary
  Corporation.

       10.2  Non-transferability.  All Options granted under this Plan
  shall be non-transferable by the Optionee, other than by will or the laws
  of descent and distribution, and shall be exercisable during the
  Optionee's lifetime only by the Optionee.  No Option may be assigned,
  pledged, hypothecated or otherwise alienated or encumbered (whether by
  operation of law or otherwise), and any attempt to do so shall be null
  and void.

                                 ARTICLE XI
               OPTIONEE-EMPLOYEE'S TRANSFER OR LEAVE OF ABSENCE

       11.1  Optionee-Employee's Transfer or Leave of Absence.  For
  purposes of this Plan:

            (a)  A transfer of an Optionee who is an Employee from the
  Company to a Subsidiary Corporation or Parent Corporation, or from one
  such Corporation to another, or

            (b)  A leave of absence for such an Optionee (i) which is duly
  authorized in writing by the Company or a Subsidiary Corporation, and
  (ii) if the Optionee holds an Incentive Stock Option, which qualifies
  under the applicable regulations under the Code which apply in the case
  of incentive stock options, shall not be deemed a termination of
  employment.  However, under no circumstances may an Optionee exercise an
  Option during any leave of absence, unless authorized by the Board.

                                 ARTICLE XII
             AMENDMENT, MODIFICATION, AND TERMINATION OF THE PLAN

       12.1  Amendment, Modification an d Termination of the Plan.

            (a)  The Board may at any time terminate, and from time to time
  may amend or modify the Plan; provided, however, that no such action of
  the Board, without approval of the shareholders, may:

                 (i)  increase the total amount of Stock which may be
  purchased through Options granted under the Plan, except as provided in
  Article V;

                 (ii)  change the class of Employees or Consultants
  eligible to receive Options; or

                 (iii)  extend the maximum option period provided in this
  Plan.

            (b)  No amendment, modification, or termination of the Plan
  shall in any manner adversely affect any outstanding Option under the
  Plan without the consent of the Optionee holding the Option.

                                 ARTICLE XIII
                      ACQUISITION, MERGER OR LIQUIDATION

       13.1  Acquisition.

            (a)  In the event that an Acquisition occurs with respect to
  the Company, the Company shall have the option, but not the obligation,
  to cancel Options outstanding as of the effective date of Acquisition,
  whether or not such Options are then exercisable, in return for payment
  to the Optionees of an amount equal to a reasonable estimate of an amount
  (hereinafter the "Spread") equal to the difference between the net amount
  per share payable in the Acquisition or as a result of the Acquisition,
  less the exercise price of the Option.  In estimating the Spread,
  appropriate adjustments to give effect to the existence of the Options





    
                                                           PAGE 37

  shall be made, such as deeming the Options to have been exercised, with
  the Company receiving the exercise price payable thereunder, and treating
  the stock receivable upon exercise of the Options as being outstanding in
  determining the net amount per share.

            (b)  For purposes of this section, an "Acquisition" means any
  transaction in which substantially all of the Company's assets are
  acquired or in which a controlling amount of the Company's outstanding
  shares of Stock are acquired, in each case by a single person or entity
  or an affiliated group of persons and entities.  For purposes of this
  section, a controlling amount shall mean more than 50% of the issued and
  outstanding shares of Stock of the Company.  The Company shall have such
  an option regardless of how the Acquisition is effectuated, whether by
  direct purchase, through a merger or similar corporate transaction, or
  otherwise.  In cases where the acquisition consists of the acquisition of
  assets of the Company, the net amount per share shall be calculated on
  the basis of the net amount receivable with respect to shares upon a
  distribution and liquidation by the Company after giving effect to
  expenses and charges, including but not limited to taxes, payable by the
  Company before the liquidation can be completed.

            (c)  Where the Company does not exercise its option under this
  Section 13.1 the remaining provisions of this Article XIII shall apply,
  to the extent applicable.

       13.2  Merger or Consolidation.  Subject to any required action by
  the shareholders, if the Company shall be the surviving corporation in
  any  merger or consolidation, any option granted under this Plan shall
  pertain to and apply to the securities to which a holder of the number of
  shares of Stock subject to the Option would have been entitled in such
  merger or consolidation.

       13.3  Other Transactions.  A dissolution or a liquidation of the
  Company or a merger and consolidation in which the Company is not the
  surviving corporation shall cause every Option outstanding hereunder to
  terminate as of the effective date of such dissolution, liquidation,
  merger or consolidation.  However, the Optionee either (i) shall be
  offered a firm commitment whereby the resulting or surviving corporation
  in a merger or consolidation will tender to the Optionee an option (the
  "Substitute Option") to purchase its shares on terms and conditions both
  as to number of shares and otherwise, that will substantially preserve to
  the Optionee the rights and benefits of the Option outstanding hereunder
  granted by the Company, or (ii) shall have the right immediately prior to
  such dissolution, liquidation, merger, or consolidation to exercise any
  unexercised Options whether or not then exercisable, subject to the
  provisions of this Plan.  The Board shall have absolute and uncontrolled
  discretion to determine whether the Optionee has been offered a firm
  commitment and whether the tendered Substitute Option will substantially
  preserve to the Optionee the rights and benefits of the Option
  outstanding hereunder.  In any event, any Substitute Option for an
  Incentive Stock Option shall comply with the requirements of Code Section
  425(a).

                                  ARTICLE XIV
                            SECURITIES REGISTRATION

       14.1  Securities Registration.  In the event that the Company shall
  deem it necessary or desirable to register under the Securities Act of
  1933, as amended, or any other applicable statute, any Options or any
  Stock with respect to which an Option may be or shall have been granted
  or exercised, or to qualify any such Options or Stock under the
  Securities Act of 1933, as amended, or any other statute, then the
  Optionee shall cooperate with the Company and take such action as is
  necessary to permit registration or qualification of such Options or
  Stock.

       14.2  Representations.  Unless the Company has determined that the
  following representation is unnecessary, each person exercising an Option
  under the Plan may be required by the Company, as a condition to the
  issuance of the shares pursuant to exercise of the Option, to make a
  representation in writing (i) that he is acquiring such shares for his
  own account for investment and not with a view to, or for sale in
  connection with, the distribution of any part thereof, (ii) that before
  any transfer in connection with the resale of such shares, he will obtain
  the written opinion of counsel for the Company, or other counsel
  acceptable to the Company, that such shares may be transferred.  The
  Company may also require that the certificates representing such shares
  contain legends reflecting the foregoing.

                                  ARTICLE XV
                                 TAX WITHHOLDING

       15.1  Tax Withholding.  Whenever shares of Stock are to be issued in
  satisfaction of Options exercised under this Plan, the Company shall have
  the power to require the recipient of the Stock to remit to the Company
  an amount sufficient to satisfy any applicable federal, state, and local
  withholding tax requirements.

                                  ARTICLE XVI
                                INDEMNIFICATION

       16.1  Indemnification.  To the extent permitted by law, each person
  who is or shall have been a member of the Board shall be indemnified and
  held harmless by the Company against and from any loss, cost, liability,
  or expense that may be imposed upon or reasonably incurred by him in
  connection with or resulting from any claim, action, suit, or proceeding
  to which he may be a party or in which he may be involved by reason of
  any action taken or failure to act under the Plan and against and from
  any and all amounts paid by him in settlement thereof, with the Company's
  approval, or paid by him in satisfaction of judgment in any such action,
  suit, or proceeding against him, provided he shall give the Company an
  opportunity, at its own expense, to handle and defend the same before he
  undertakes to handle and defend it on his own behalf.  The foregoing
  right of indemnification shall not be exclusive of any other rights of
  indemnification to which such persons may be entitled under the Company's
  articles of incorporation or bylaws, as a matter of law, or otherwise, or
  any power that the Company or any Subsidiary Corporation may have to
  indemnify them or hold them harmless.

       17.1  Requirements of Law.  The granting of Options and the issuance
  of shares of Stock upon the exercise of an Option shall be subject to all
  applicable laws, rules, and regulations, and to such approvals by any
  governmental agencies or national securities exchanges as may be
  required.

  be construed in accordance with and governed by the laws of the state of

                                 ARTICLE XIX
                             COMPLIANCE WITH CODE

       19.1  Compliance with Code.  Incentive Stock Options granted
  hereunder are intended to qualify as "incentive stock options" under Code
  422A.  If any provision of this Plan is susceptible to more than one
  interpretation, such interpretation shall be given thereto as is
  consistent with Incentive Stock Options granted under this Plan being
  treated as incentive stock options under the Code.

                                  ARTICLE XX
                       NO OBLIGATION TO EXERCISE OPTION

       20.1  No Obligation to Exercise.  The granting of an Option shall
