                            TO BE HELD JULY 14, 2000

                                  INTRODUCTION

      This Proxy Statement is furnished in connection with the solicitation of
proxies by the Board of Directors of BioSource International, Inc., a Delaware
corporation (the "Company"), for use at the 2000 Annual Meeting of Stockholders
(the "Annual Meeting") to be held at the Hyatt Westlake Plaza, 880 South
Westlake Boulevard, Westlake Village, California, 91361, on July 14, 2000 at
9:00 a.m., Pacific Standard time, and at any adjournments or postponements
thereof, for the purposes set forth herein and in the attached Notice of Annual
Meeting of Stockholders. Accompanying this Proxy Statement is the Board of
Directors' Proxy for the Annual Meeting, which you may use to indicate your vote
on the proposals described in this Proxy Statement.

      All Proxies which are properly completed, signed and returned to us prior
to the Annual Meeting, and which have not been revoked, will unless otherwise
directed by the stockholder be voted in accordance with the recommendations of
the Board of Directors set forth in this Proxy Statement. A stockholder of
record may revoke his or her Proxy at any time before it is voted either by
filing with our Secretary, at our principal executive offices, a written notice
of revocation or a duly executed proxy bearing a later date, or by attending the
Annual Meeting and expressing a desire to vote his or her shares in person.

      The close of business on May 15, 2000 has been fixed as the record date
for the determination of stockholders entitled to notice of and to vote at the
Annual Meeting or at any adjournments or postponements of the Annual Meeting. At
the record date, 7,951,953 shares of common stock, par value $.001 per share,
were outstanding. Our common stock is the only outstanding class of our
securities entitled to vote at the Annual Meeting.

      It is anticipated that this Proxy Statement and the accompanying Proxy
will be mailed to stockholders on or about May 19, 2000.

                                VOTING PROCEDURES

      A stockholder is entitled to cast one vote for each share held of record
on the record date on all matters to be considered at the Annual Meeting. The
seven nominees for election as directors at the Annual Meeting who receive the
highest number of affirmative votes will be elected. Abstentions and broker
non-votes will be included in the number of shares present at the Annual Meeting
for the purpose of determining the presence of a quorum. Abstentions will be
counted toward the tabulation of votes cast on proposals submitted to
stockholders and will have the same effect as negative votes, while broker
non-votes will not be counted as votes cast for or against such matters.

                              ELECTION OF DIRECTORS

      In accordance with our Bylaws, the Board of Directors has fixed the number
of directors at seven. At each annual meeting of stockholders, seven directors
are elected, each for a one-year term. Seven directors will be elected at the
Annual Meeting.

      Unless otherwise instructed, the Proxy holders will vote the Proxies
received by them for the nominees named below. If any nominee is unable or
unwilling to serve as a director at the time of the Annual Meeting or any
postponements or adjournments, the Proxies will be voted for such other
nominee(s) as shall be designated by the current Board of Directors to fill any
vacancy. We have no reason to believe that any nominee will be unable or
unwilling to serve if elected as a director.

      The Board of Directors proposes the election of the following nominees as
directors:

                              James H. Chamberlain
                              Jean-Pierre L. Conte
                             Leonard M. Hendrickson
                              David J. Moffa, Ph.D.
                              John R. Overturf, Jr.
                                 Robert D. Weist
                                Robert J. Weltman

      If elected, each nominee is expected to serve until the 2001 Annual
Meeting of Stockholders. The seven nominees for election as directors at the
Annual Meeting who receive the highest number of affirmative votes will be
elected.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE ELECTION OF THE
NOMINEES LISTED ABOVE.

EMPLOYMENT AGREEMENTS WITH EXECUTIVE OFFICERS

     Effective as of January 2, 1998, and amended as of December 17, 1999, James
Chamberlain entered into an employment agreement with us which superseded Mr.
Chamberlain's existing employment agreement dated January 2, 1996. The term of
the employment agreement is three years. Pursuant to the terms of the employment
agreement, Mr. Chamberlain is to be paid an annual salary of $250,000 for each
year of the agreement, an annual bonus determined on the basis of our existing
management incentive plan which is limited to $100,000 for each year of the
agreement and is to receive certain additional benefits.

     In the event there is a "change of control" of the Company, Mr. Chamberlain
may terminate his employment agreement, in which case, we are obligated to
continue to pay Mr. Chamberlain his then-current base salary for a period of 24
months following the effective date of such termination. A "change of control"
includes (i) the acquisition by any person or entity of shares of our capital
stock entitled to exercise 35% or more of the total voting power of our
stockholders, (ii) the execution by us of an agreement to sell or otherwise
transfer all or substantially all of our assets or the execution by us of an
agreement to merge, consolidate or reorganize with any other corporation or
entity, which results in less than 75% of the total voting power represented by
the capital stock or other equity interests of the corporation or entity to
which our assets are sold or transferred or surviving such merger, consolidation
or reorganization being held by the persons and entities who were holders of our
common stock immediately prior to such agreement, (iii) the issuance by us,
otherwise than on a pro rata basis, of additional shares of capital stock
representing (after giving effect to such issuance) more than 35% of the total
voting power of our stockholders, or (iv) if the persons who were our directors
as of the date of the agreement cease to comprise a majority of our Board of
Directors.

     Effective as of December 17, 1999, Gus E. Davis, Charles C. Best and
Richard O. Buford each entered into a separation agreement with us. In the event
we experience a "change of control," and the employment of any one of these
three executives with us is terminated within one year of the "change of
control," we are obligated to continue to pay the terminated executive his
then-current base salary for a period of 12 months following the effective date
of such termination. A "change of control" includes (i) the acquisition by any
person or entity of shares of our capital stock entitled to exercise 35% or more
of the total voting power of our stockholders, (ii) the execution by us of an
agreement to sell or otherwise transfer all or substantially all of our assets
or the execution by us of an agreement to merge, consolidate or reorganize with
any other corporation or


                                     Page 7
<PAGE>


entity, which results in less than 75% of the total voting power represented by
the capital stock or other equity interests of the corporation or entity to
which our assets are sold or transferred or surviving such merger, consolidation
or reorganization being held by the persons and entities who were holders of our
common stock immediately prior to such agreement, (iii) the issuance by us,
otherwise than on a pro rata basis, of additional shares of capital stock
representing (after giving effect to such issuance) more than 35% of the total
voting power of our stockholders, or (iv) if the persons who were our directors
as of the date of each separation agreement cease to comprise a majority of our
Board of Directors.

STOCK OPTION PLANS

     We adopted a Stock Option Plan (the "1993 Plan") in 1993. The purpose of
the 1993 Plan is to attract, retain and motivate certain of our key employees by
giving them incentives which are linked directly to increases in the value of
our common stock. Each of our officers, directors and employees and under
certain circumstances, our consultants are eligible to be considered for the
grant of awards under the 1993 Plan. The maximum number of shares of common
stock that may be issued pursuant to awards granted under the 1993 Plan is
2,000,000, subject to certain adjustments to prevent dilution. Any shares of
common stock subject to an award which for any reason expires or terminates
unexercised are again available for issuance under the 1993 Plan.

     The 1993 Plan authorizes the Compensation Committee to enter into any type
of arrangement with an eligible employee that, by its terms, involves or might
involve the issuance of (1) shares of our common stock, (2) an option, warrant,
convertible security, stock appreciation right or similar right with an exercise
or conversion privilege at a price related to our common stock, or (3) any other
security or benefit with a value derived from the value of our common stock. Any
stock option granted may be an incentive stock option within the meaning of
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code") or a
nonqualified stock option. The 1993 Plan currently is administered by the
Compensation Committee of our Board of Directors. Subject to the provisions of
the 1993 Plan, the Compensation Committee will have full and final authority to
select the executives and other employees to whom awards will be granted
thereunder, to grant the awards and to determine the terms and conditions of the
awards and the number of shares to be issued pursuant thereto.

     As of May 1, 2000, the Board had granted options covering an aggregate of
2,000,000 shares of common stock to certain of our directors, officers and
employees, of which options to purchase 1,272,956 shares were outstanding.

     The Board of Directors has also adopted the BioSource International, Inc.
2000 Stock Incentive Plan as of March 15, 2000, subject to stockholder approval.
If the plan is not approved by the holders of our common stock at the Annual
Meeting, it will not become effective. As of May 1, 2000, no options have been
granted under the 2000 Stock Incentive Plan. For a summary of the plan, please
see "Proposal No. 2: Proposal to Adopt New Stock Incentive Plan," beginning on
page 13 of this Proxy Statement. A copy of the plan is attached to this Proxy
Statement as Appendix A.

            COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     None of the members of the Compensation Committee is a current or former
officer or employee of the Company.

                          COMPENSATION COMMITTEE REPORT

     The Compensation Committee of the Board of Directors determines
compensation paid to each of our executive officers and administers the 1993
Stock Option.

     The objectives of our executive compensation policy include (1) attracting,
motivating and retaining talented executives by providing compensation that is
competitive with comparable companies, (2) maintaining compensation levels that
are consistent with the company's financial objectives and operating performance
and (3) aligning the interests of executive officers and stockholders through
bonuses based on the company's performance and by providing equity compensation.
Our compensation program currently consists of base salary and incentive
compensation in the form of cash bonuses and/or stock options.


                                     Page 8
<PAGE>


     In arriving at an initial compensation offer to an individual, the
Compensation Committee considers determinants of the individual's market value
including experience, education, accomplishments and reputation, as well as the
level of responsibility to be assumed, in relation to the market value of such
qualifications and industry standards. When determining subsequent adjustments
to an individual's annual salary, the Compensation Committee also evaluates the
importance to stockholders of that person's continued service. The Compensation
Committee also reviews the annual salaries of our executive officers in relation
to the company's financial performance, annual budgeted financial goals and its
position in the industry. This is a judgment process, exercised by the
Compensation Committee with the advice of management and other consultants.

     Cash bonuses were awarded for during the past year, which were determined
on the basis of accomplishments measured against a management incentive plan
that was prepared by management and approved by the Compensation Committee.

     Stock options are prospective incentives, aimed at keeping and motivating
key people by letting them share in the value they create for stockholders. They
are awarded at times deemed appropriate by the Compensation Committee in amounts
intended to secure the full attention and best efforts of executives upon whose
future performance the company's success will depend.

     During 1999, Larry A. May, one of our executive officers, resigned. The
company hired one new executive officer, Charles C. Best, as Chief Financial
Officer and Executive Vice President of Finance. In setting a base salary for
Mr. Best, the Compensation Committee took into account the salary ranges of
industry competitors, his prior experience and expected contributions, and the
relative importance of his position in terms of achieving the company's
objectives.

     The company's Chief Executive Officer, James H. Chamberlain, received a
base salary of $250,000 in 1999 and a cash bonus in the amount of $90,000. Mr.
Chamberlain's salary was established based upon a comparative analysis of other
similarly situation chief executive officers conducted by the compensation
committee. Mr. Chamberlain also participated in the management incentive plan
approved by the Compensation Committee.

              SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Securities Exchange Act of 1934, requires our
executive officers, directors, and persons who own more than ten percent of a
registered class of our equity securities to file reports of ownership and
changes in ownership with the Securities and Exchange Commission (the "SEC").
Executive officers, directors and greater-than-ten percent stockholders are
required by SEC regulations to furnish us with all Section 16(a) forms they
file. Based solely on our review of the copies of the forms received by us and
written representations from certain reporting persons that they have complied
with the relevant filing requirements, we believe that, during the year ended
December 31, 1999, all our executive officers, directors and greater-than-ten
percent stockholders complied with all Section 16(a) filing requirements, except
for the following; Charles Best filed a Form 3 reporting his initial appointment
as our Chief Financial Officer and Executive Vice President which was not timely
filed, and James H. Chamberlain, Leonard M. Hendrickson and David J. Moffa,
Ph.D. each reported events on a Form 5 filed prior to February 15, 2000, with
respect to transactions that occurred in 1999 and should have been reported on a
Form 4.

                     RELATIONSHIPS AND RELATED TRANSACTIONS
                      WITH DIRECTORS AND EXECUTIVE OFFICERS

     Our Chief Executive Officer and President, James H. Chamberlain, is
indebted to us in the aggregate principal amount of $350,000 as of March 1,
2000. The loan is represented by a promissory note in the principal amount of
$350,000, bearing interest at 5.9% per year. The loan provides for interest only
payments, payable quarterly, with all principal due upon demand.

     On January 10, 2000, we entered into a securities purchase agreement with
Genstar Capital Partners II, L.P. and Stargen II LLC. Pursuant to this
agreement, we sold Genstar and Stargen a total of 371,300 shares, including
364,244 to Genstar and 7,056 to Stargen, of our Series B Preferred Stock for
$9,000,312 in the aggregate. These shares are convertible into 1,485,200 shares,
including 1,456,976 for Genstar and 28,224 for Stargen, of our common stock. In
addition, we issued to Genstar and Stargen warrants to purchase a total of
1,287,000 shares of our common stock, including 1,262,542 to Genstar and 24,458
to Stargen, exercisable at $7.77 per share. Under the investor rights agreement
among Genstar, Stargen and us, executed in connection with the securities
purchase agreement, Genstar and Stargen also have the right to appoint two out
of our seven directors to our Board of Directors as long as they beneficially
own, in the aggregate, at least 750,000 shares of common stock, or one director
if they beneficially own at least 495,000 shares. Pursuant to the investor
rights agreement, we appointed Jean-Pierre L. Conte, a Managing Director of
Genstar Capital LLC, and Robert J. Weltman, a Vice President of Genstar Capital
LLC, to our Board of Directors. Genstar and Stargen also have the right of first
refusal to purchase additional shares and the right to require us to register
their shares of our common stock underlying the preferred stock and the
warrants. The consummation of the securities purchase agreement, including the
issuance of the shares of Series B Preferred Stock and the warrants, occurred on
February 15, 2000. Pursuant to the securities purchase agreement, we paid a
$270,009 transaction fee to Genstar Capital LLC and reimbursed all of the fees
and expenses of approximately $195,426, incurred by Genstar Capital Partners and
its affiliates in connection with the securities purchase agreement.

     We purchased our principal executive offices located in Camarillo,
California, on March 28, 1996, and own it subject to a first trust deed mortgage
that was made by the lender pursuant to the Small Business Administration's Loan
Guarantee Program. The property is subject to a second trust deed loan with the
California Statewide Development Corp. Our payments under these mortgages are
unconditionally guaranteed by James H. Chamberlain, our Chief Executive Officer.

                              PROPOSAL TO ADOPT NEW
                              STOCK INCENTIVE PLAN

     The BioSource International, Inc. 2000 Stock Incentive Plan was adopted by
our Board of Directors as of March 15, 2000, subject to stockholder approval.
The plan authorizes the granting of awards of stock or stock purchase rights and
options to purchase an aggregate of 2,000,000 shares of our common stock. Under
the plan, stock options and purchase rights may be granted to employees,
consultants, officers and directors who will contribute to our long range
success and to provide incentives which are linked directly to increases in
share value which will inure to the benefit of all of our stockholders.

     The vote required for the adoption the 2000 Stock Incentive Plan is the
affirmative vote of a majority of the holders of common stock present, in person
or by proxy, and entitled to vote at the Annual Meeting. If the plan is not
approved by the holders of our common stock, it will not become effective. The
principal provisions of the plan are summarized below. However, this summary is
not complete and is qualified in its entirety by the terms of the plan. A copy
of our 2000 Stock Plan is attached as Appendix A and is incorporated into this
Proxy Statement by reference.

ADMINISTRATION OF THE 2000 STOCK PLAN

     The plan provides for administration by the Board of Directors or a
committee of the Board of Directors. Initially, the Compensation Committee of
the Board of Directors will administer the plan, including, without limitation,
selecting the persons who will be granted stock awards and/or stock options, the
number of shares and options to be awarded to each person, the purchase price or
exercise price of any awards, and the vesting requirements of awards of stock or
options. The Board of Directors may amend, suspend or terminate the plan at any
time for any reason, although some amendments may by applicable law require
stockholder approval. Options and awards for a maximum of 750,000 shares of
common stock may be granted in any one calendar year.

OPTIONS

     Options granted under the plan may be either incentive stock options as
defined in section 422(b) of the Internal Revenue Code of 1986, as amended from
time to time, or non-qualified stock options. Only employees are eligible to
receive incentive stock options. Each grant of options under the plan must be
evidenced by a stock option agreement. The term of a stock option granted under
the plan may not exceed ten years and is determined by the Compensation
Committee. The exercise price of options granted under the plan is determined by
the Compensation Committee, but cannot be less 100% of the fair market value in
the case of incentive stock options and 85% of the fair market value in the case
of non-qualified stock options. In the case of 10% stockholders, the exercise
price of any options must be at least 110% of the fair market value of the
common stock and the term of any incentive stock options may not exceed five
years. Options granted to officers, directors and consultants vest according to
a schedule as determined by the Compensation Committee. Options granted to other
employees must vest at least as rapidly as 20% per year over the five-year
period beginning on the date of grant.

     If an optionee's employment is terminated for any reason other than death,
disability or termination for cause, options granted to him or her under the
plan will only be exercisable until the earlier of three months from the date of
termination or their expiration date. If termination of employment is due to the
death or disability of an optionee, his or her options will be exercisable for
one year after the date of termination. Where employment is terminated for
cause, as defined in the plan, all options of the terminated optionee will
expire as of the date of termination.

AWARDS OR SALES OF STOCK

     Awards or sales of stock under the plan must be evidenced by a stock
purchase agreement between us and the purchaser. Any rights to acquire shares
granted under the plan, other than options, will expire if not exercised within
thirty days after the grant date. Awards or sales of shares of common stock may
be made under


                                    Page 12
<PAGE>


the plan at a price per share to be determined by the Compensation Committee,
provided that the price per share is at least 85% of the fair market value.
Under this plan, the purchase price per share of any sales of common stock to a
10% stockholder must be at least 100% of the fair market value.

TRANSFER RESTRICTIONS

     A recipient under the plan may not assign, sell or transfer their options
or awards other than by will or by operation of the laws of descent and
distribution. However, the Compensation Committee may permit transfers of
non-qualified stock options to the optionee's immediate family or a trust that
provides for transfer of the options to beneficiaries upon death of the trustor.

     The plan gives us the right to repurchase options and awards for a period
of ninety days subsequent to the recipient's termination of service with us.
Under the plan, each stock option agreement and stock purchase agreement may
also give us the right of first refusal in connection with any proposed sale,
hypothecation or other disposition of common stock acquired under the stock
option agreement or stock purchase agreement.

REORGANIZATIONS AND RECAPITALIZATIONS

     The number of shares of common stock covered by each outstanding option or
purchase right, and the exercise or purchase price per share, shall be
proportionately adjusted for any increase or decrease in the number of issued
shares of common stock resulting from a subdivision or consolidation of shares
or the payment of a stock dividend on our common stock or any other increase or
decrease in the number of such shares effected without receipt of consideration
by us.

     In the event of a dissolution, liquidation, sale of all or substantially
all our assets, merger or consolidation or similar occurrence, we may provide
for (i) the continuation of outstanding options and purchase rights if we are
the surviving corporation in a merger, (ii) the assumption of the outstanding
options and purchase rights by the surviving corporation, (iii) the substitution
by the surviving corporation of substantially similar options or purchase rights
or (iv) the cancellation of outstanding options and purchase rights. If we elect
to cancel the outstanding options and purchase rights, the optionee or award
recipient will have the opportunity to exercise his or her options or purchase
rights.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     The following is a brief summary of certain federal income tax consequences
of option grants and exercises under the plan based upon the federal income tax
laws in effect on the date hereof. This summary is not intended to be exhaustive
and does not describe state or local tax consequences.

     The grant of incentive stock options to an employee does not result in any
income tax consequences. The exercise of an incentive stock option does not
result in any income tax consequences to the employee if the incentive stock
option is exercised by the employee during his or her employment with us, or
within a specified period after termination of employment due to death or
retirement for age or disability. However, the excess of the fair market value
of the shares of stock as of the date of exercise over the option price is a tax
preference item for purposes of determining an employee's alternative minimum
tax. An employee who sells shares acquired pursuant to the exercise of an
incentive stock option after the expiration of (i) two years from the date of
grant of the incentive stock option, and (ii) one year after the transfer of the
shares to him or her will generally recognize long term capital gain or loss on
the sale. An employee who disposes of his or her incentive stock option shares
prior to the expiration of the waiting period generally will recognize ordinary
income in the year of sale in an amount equal to the lesser of (i) the fair
market value of the shares as of the date of exercise or (ii) the amount
realized on the sale, over the option price. Any additional amount realized on
an early disposition should be treated as capital gain to the employee, short or
long term, depending on the employee's holding period for the shares. If the
shares are sold for less than the option price, the employee will not recognize
any ordinary income but will recognize a capital loss, short or long term,
depending on the holding period.

<PAGE>


     We will not be entitled to a deduction as a result of the grant of an
incentive stock option, the exercise of an incentive stock option, or the sale
of incentive stock option shares after the waiting period. If an employee
disposes of his or her incentive stock option shares in an early disposition, we
will be entitled to deduct the amount or ordinary income recognized by the
employee.

     The grant of non-qualified stock options under the plan will not result in
the recognition of any taxable income by the participants. A participant may
recognize ordinary income on the date of exercise of the non-qualified stock
option equal to the difference between the fair market value on that date of the
shares acquired and the exercise price. The tax basis of these shares for
purpose of a subsequent sale includes the option price paid and the ordinary
income reported on exercise of the option. The income reportable on exercise of
the option by an employee is subject to federal and state income and employment
tax withholding.

     Generally, the Company will be entitled to a deduction in the amount
reportable as income by the participant on the exercise of a non-qualified stock
option.

     As of May 15, 2000, no option or stock awards have been granted under the
2000 Stock Incentive Plan.

(1)  Under Rule 13d-3, certain shares may be deemed to be beneficially owned by
     more than one person (if, for example, persons share the power to vote or
     the power to dispose of the shares). In addition, shares are deemed to be
     beneficially owned by a person if the person has the right to acquire the
     shares (for example, upon exercise of an option) within 60 days of the date
     as of which the information is provided. In computing the percentage
     ownership of any person, the amount of shares outstanding is deemed to
     include the amount of shares beneficially owned by such person (and only
     such person) by reason of these acquisition rights. As a result, the
     percentage of outstanding shares of any person as shown in this table does
     not necessarily reflect the person's actual ownership or voting power with
     respect to the number of shares of common stock actually outstanding at May
     1, 2000.

     3.4 DECISIONS FINAL. All decisions made by the Administrator pursuant to
the provisions of the Plan shall be final and binding on the Company and the
Participants.

     3.5 THE COMMITTEE. The Board may, in its sole and absolute discretion, from
time to time, and at any period of time during which the Company's Stock is
registered pursuant to Section 12 of the Exchange Act shall, delegate any or all
of its duties and authority with respect to the Plan to the Committee whose
members are to be appointed by and to serve at the pleasure of the Board. From
time to time, the Board may increase or decrease the size of the Committee, add
additional members to, remove members (with or without cause) from, appoint new
members in substitution therefor, and fill vacancies, however caused, in the
Committee. The Committee shall act pursuant to a vote of the majority of its
members or, in the case of a committee comprised of only two members, the
unanimous consent of its members, whether present or not, or by the written
consent of the majority of its members or, in the case of a Committee comprised
of only two members, the unanimous written consent of its members, and minutes
shall be kept of all of its meetings and copies thereof shall be provided to the
Board. Subject to the limitations prescribed by the Plan and the Board, the
Committee may establish and follow such rules and regulations for the conduct of
its business as it may determine to be advisable. During any period of time
during which the Company's Stock is registered pursuant to Section 12 of the
Exchange Act, all members of the Committee shall be Non-Employee Directors and
Outside Directors.

     3.6 INDEMNIFICATION. In addition to such other rights of indemnification as
they may have as Directors or members of the Committee, and to the extent
allowed by applicable law, the Administrator shall be indemnified by the Company
against the reasonable expenses, including attorney's fees, actually incurred in
connection with any action, suit or proceeding or in connection with any appeal
therein, to which the Administrator may be party by reason of any action taken
or failure to act under or in connection with the Plan or any option granted
under the Plan, and against all amounts paid by the Administrator in settlement
thereof (provided that the settlement has been


                                     Page 4
<PAGE>


approved by the Company, which approval shall not be unreasonably withheld) or
paid by the Administrator in satisfaction of a judgment in any such action, suit
or proceeding, except in relation to matters as to which it shall be adjudged in
such action, suit or proceeding that such Administrator did not act in good
faith and in a manner which such person reasonably believed to be in the best
interests of the Company, and in the case of a criminal proceeding, had no
reason to believe that the conduct complained of was unlawful; PROVIDED,
HOWEVER, that within 60 days after institution of any such action, suit or
proceeding, such Administrator shall, in writing, offer the Company the
opportunity at its own expense to handle and defend such action, suit or
proceeding.

                     SECTION 4: STOCK SUBJECT TO THE PLAN

     4.1 STOCK SUBJECT TO THE PLAN. Subject to adjustment as provided in Section
9, 2,000,000 shares of Common Stock ($.001 par value) shall be reserved and
available for issuance under the Plan. Stock reserved hereunder may consist, in
whole or in part, of authorized and unissued shares or treasury shares.

     4.2 BASIC LIMITATION. The maximum number of shares with respect to which
Options, awards or sales of Stock may be granted under the Plan to any
Participant in any one calendar year shall be 750,000 shares. The number of
shares that are subject to Rights under the Plan shall not exceed the number of
shares that then remain available for issuance under the Plan. The Company,
during the term of the Plan, shall at all times reserve and keep available a
sufficient number of shares to satisfy the requirements of the Plan. 4.3
ADDITIONAL SHARES. In the event that any outstanding Option or other right for
any reason expires or is canceled or otherwise terminated, the shares allocable
to the unexercised portion of such Option or other right shall again be
available for the purposes of the Plan. In the event that shares issued under
the Plan are reacquired by the Company pursuant to the terms of any forfeiture
provision, right of repurchase or right of first refusal, such shares shall
again be available for the purposes of the Plan.

                            SECTION 5: ELIGIBILITY

     Eligible Persons who are selected by the Administrator shall be eligible to
be granted Rights hereunder subject to limitations set forth in this Plan;
PROVIDED, HOWEVER, that only employees shall be eligible to be granted ISOs
hereunder.

                  SECTION 6: TERMS AND CONDITIONS OF OPTIONS.

     6.1 STOCK OPTION AGREEMENT. Each grant of an Option under the Plan shall be
evidenced by a Stock Option Agreement between the Optionee and the Company. Such
Option shall be subject to all applicable terms and conditions of the Plan and
may be subject to any other terms and conditions which are not inconsistent with
the Plan and which the Administrator deems appropriate for inclusion in a Stock
Option Agreement. The provisions of the various Stock Option Agreements entered
into under the Plan need not be identical.

     6.2 NUMBER OF SHARES. Each Stock Option Agreement shall specify the number
of shares of Stock that are subject to the Option and shall provide for the
adjustment of such number


                                     Page 5
<PAGE>


in accordance with Section 9, hereof. The Stock Option Agreement shall also
specify whether the Option is an ISO or a Non-Qualified Stock Option.

     6.3 EXERCISE PRICE.

     6.3.1 IN GENERAL. Each Stock Option Agreement shall state the price at
which shares subject to the Stock Option may be purchased (the "EXERCISE
PRICE"), which shall, with respect to Incentive Stock Options, be not less than
100% of the Fair Market Value of the Stock on the Date of Grant. In the case of
Non-Qualified Stock Options, the Exercise Price shall be determined in the sole
discretion of the Administrator; PROVIDED, HOWEVER, that the Exercise Price
shall be no less than 85% of the Fair Market Value of the shares of Stock on the
Date of Grant of the Non-Qualified Stock Option.

     6.3.2 TEN-PERCENT STOCKHOLDERS. An individual who owns more than 10% of the
total combined voting power of all classes of outstanding stock of the Company,
its Parent or any of its Subsidiaries shall not be eligible for designation as
an Optionee or Purchaser, unless (i) the Exercise Price of a Non-Qualified Stock
Option is at least 110% of the Fair Market Value of a Share on the Date of
Grant, or (ii) in the case of an ISO, the Exercise Price is at least 110% of the
Fair Market Value of a Share on the Date of Grant and such ISO by its terms is
not exercisable after the expiration of five years from the Date of Grant.

     6.3.3 NON-APPLICABILITY. The Exercise Price restriction applicable to
Non-Qualified Stock Options required by Sections 6.3.1 and 6.3.2(i) shall be
inoperative if (i) the shares to be issued upon payment of the Exercise Price
have been registered under a then currently effective registration statement
under applicable federal or state securities laws, or (ii) a determination is
made by counsel for the Company that such Exercise Price restrictions are not
required in the circumstances under applicable federal or state securities laws.

     The Exercise Price shall be payable in a form described in Section 8,
hereof.

     6.4 WITHHOLDING TAXES. As a condition to the exercise of an Option, the
Optionee shall make such arrangements as the Board may require for the
satisfaction of any federal, state, local or foreign withholding tax obligations
that may arise in connection with such exercise or with the disposition of
shares acquired by exercising an Option.

     6.5 TERM. The Stock Option Agreement shall specify, the term of the Option.
No Option shall be exercised after the expiration of ten years after the date
the Option is granted. In addition, no option may be exercised (i) three months
after the date the Optionee's Service with the Company, its Parent or its
Subsidiaries terminates if such termination is for any reason other than death,
Disability or Cause, (ii) one year after the date the Optionee's Service with
the Company and its subsidiaries terminates if such termination is a result of
death or Disability, and (iii) if the Optionee's Service with the Company and
its Subsidiaries terminates for Cause, all outstanding Options granted to such
Optionee shall expire as of the commencement of business on the date of such
termination; PROVIDED, HOWEVER, that the Stock Option Agreement for any Option
may provide for longer or shorter periods, and the Administrator may, in its
sole discretion, waive the accelerated expiration provided for in (i) or (ii).
Outstanding Options that are not exercisable at the time of termination of
employment for any reason shall expire at the close of business on the date of
such termination. In the case of an ISO granted to an employee who owns stock
possessing more than


                                     Page 6
<PAGE>


10% of the total combined voting power of all classes of stock of the Company or
any of its Parent or Subsidiary corporations, the term set forth in (i), above,
shall not be more than five years after the date the Option is granted.

     6.6 LEAVES OF ABSENCE. For purposes of Section 6.6 above, Service shall be
deemed to continue while the Optionee is on a bona fide leave of absence, if
such leave was approved by the Company in writing and if continued crediting of
Service for this purpose is expressly required by the terms of such leave or by
applicable law (as determined by the Administrator).

     6.7 MODIFICATION, EXTENSION AND ASSUMPTION OF OPTIONS. Within the
limitations of the Plan, the Administrator may modify, extend or assume
outstanding Options or may accept the cancellation of outstanding Options
(whether granted by the Company or another issuer) in return for the grant of
new Options for the same or a different number of shares and at the same or a
different Exercise Price. The foregoing notwithstanding, no modification of an
Option shall, without the consent of the Optionee, impair the Optionee's rights
or increase the Optionee's obligations under such Option. However, a termination
of the Option in which the Optionee receives a cash payment equal to the
difference between the Fair Market Value and the Exercise Price for all shares
subject to exercise under any outstanding Option shall not be deemed to impair
any rights of the Optionee or increase the Optionee's obligations under such
Option.

              SECTION 7: TERMS AND CONDITIONS OF AWARDS OR SALES

     7.1 STOCK PURCHASE AGREEMENT. Each award or sale of shares under the Plan
(other than upon exercise of an Option) shall be evidenced by a Stock Purchase
Agreement between the Purchaser and the Company. Such award or sale shall be
subject to all applicable terms and conditions of the Plan and may be subject to
any other terms and conditions which are not inconsistent with the Plan and
which the Board deems appropriate for inclusion in a Stock Purchase Agreement.
The provisions of the various Stock Purchase Agreements entered into under the
Plan need not be identical.

     7.2 DURATION OF OFFERS. Any right to acquire shares under the Plan (other
than an Option) shall automatically expire if not exercised by the Purchaser
within 30 days after the grant of such right was communicated to the Purchaser
by the Company.

     7.3 PURCHASE PRICE.

     7.3.1 IN GENERAL. Each Stock Purchase Agreement shall state the price at
which the Stock subject to such Stock Purchase Agreement may be purchased (the
"PURCHASE PRICE"), which, with respect to Stock Purchase Rights, shall be
determined in the sole discretion of the Administrator; PROVIDED, HOWEVER, that
the Purchase Price shall be no less than 85% of the Fair Market Value of the
shares of Stock on either the Date of Grant or the date of purchase of the
Purchase Right.

     7.3.2 TEN-PERCENT STOCKHOLDERS. An individual who owns more than 10% of the
total combined voting power of all classes of outstanding stock of the Company,
its Parent or any of its Subsidiaries shall not be eligible for designation as a
Purchaser unless the Purchase Price (if any) is at least 100% of the Fair Market
Value of a Share.


                                     Page 7
<PAGE>


     7.3.3 NON APPLICABILITY. The Purchase Price restrictions required by
Sections 7.3.1 and 7.3.2 shall be inoperative if (i) the shares to be issued
upon payment of the Purchase Price have been registered under a then currently
effective registration statement under applicable federal or state securities
laws, or (ii) a determination is made by counsel for the Company that such
Purchase Price restrictions are not required in the circumstances under
applicable federal or state securities laws.

     The Purchase Price shall be payable in a form described in Section 8.

     7.4 WITHHOLDING TAXES. As a condition to the purchase of shares, the
Purchaser shall make such arrangements as the Board may require for the
satisfaction of any federal, state, local or foreign withholding tax obligations
that may arise in connection with such purchase.

                       SECTION 8: PAYMENT; RESTRICTIONS

     8.1 GENERAL RULE. The entire Purchase Price or Exercise Price of shares
issued under the Plan shall be payable in full by, as applicable, cash or check
for an amount equal to the aggregate Purchase Price or Exercise Price for the
number of shares being purchased, or in the discretion of the Administrator,
upon such terms as the Administrator shall approve, (i) in the case of an
Option, by a copy of instructions to a broker directing such broker to sell the
Stock for which such Option is exercised, and to remit to the Company the
aggregate Exercise Price of such Options (a "cashless exercise"), (ii) in the
case of an Option or a sale of Stock, by paying all or a portion of the Exercise
Price or Purchase Price for the number of shares being purchased by tendering
Stock owned by the Optionee, duly endorsed for transfer to the Company, with a
Fair Market Value on the date of delivery equal to the aggregate Purchase Price
of the Stock with respect to which such Option or portion thereof is thereby
exercised or Stock acquired (a "Stock-for-Stock exercise") or (iii) by a
Stock-for-Stock exercise by means of attestation whereby the Optionee identifies
for delivery specific shares of Stock already owned by Optionee and receives a
number of shares of Stock equal to the difference between the Option shares
thereby exercised and the identified attestation shares of Stock (an
"attestation exercise").

     8.2 WITHHOLDING PAYMENT. The Purchase Price or Exercise Price shall include
payment of the amount of all federal, state, local or other income, excise or
employment taxes subject to withholding (if any) by the Company or any parent or
subsidiary corporation as a result of the exercise of a Stock Option. The
Optionee may pay all or a portion of the tax withholding by cash or check
payable to the Company, or, at the discretion of the Administrator, upon such
terms as the Administrator shall approve, by (i) cashless exercise or
attestation exercise; (ii) Stock-for-Stock exercise; (iii) in the case of an
Option, by paying all or a portion of the tax withholding for the number of
shares being purchased by withholding shares from any transfer or payment to the
Optionee ("Stock withholding"); or (iv) a combination of one or more of the
foregoing payment methods. Any shares issued pursuant to the exercise of an
Option and transferred by the Optionee to the Company for the purpose of
satisfying any withholding obligation shall not again be available for purposes
of the Plan. The Fair Market Value of the number of shares subject to Stock
withholding shall not exceed an amount equal to the applicable minimum required
tax withholding rates.

     8.3 SERVICES RENDERED. At the discretion of the Administrator, shares may
be awarded under the Plan in consideration of services rendered to the Company,
a Parent or a Subsidiary prior


                                     Page 8
<PAGE>


to the award. At the discretion of the Administrator, shares may also be awarded
under the Plan in consideration of services to be rendered to the Company, a
Parent or a Subsidiary after the award, except that the par value of such
shares, if newly issued, shall be paid in cash or cash equivalents.

   8.4 PROMISSORY NOTE. To the extent that a Stock Option Agreement or Stock
Purchase Agreement so provides, in the discretion of the Administrator, upon
such terms as the Administrator shall approve, all or a portion of the Exercise
Price or Purchase Price (as the case may be) of shares issued under the Plan may
be paid with a full-recourse promissory note. However, the par value of the
shares, if newly issued, shall be paid in cash or cash equivalents. The shares
shall be pledged as security for payment of the principal amount of the
promissory note and interest thereon. The interest rate payable under the terms
of the promissory note shall not be less than the minimum rate (if any) required
to avoid the imputation of additional interest under the Code. Subject to the
foregoing, the Administrator (at its sole discretion) shall specify the term,
interest rate, amortization requirements (if any) and other provisions of such
note. Unless the Administrator determines otherwise, shares of Stock having a
Fair Market Value at least equal to the principal amount of the loan shall be
pledged by the holder to the Company as security for payment of the unpaid
balance of the loan and such pledge shall be evidenced by a pledge agreement,
the terms of which shall be determined by the Administrator, in its discretion;
PROVIDED, HOWEVER, that each loan shall comply with all applicable laws,
regulations and rules of the Board of Governors of the Federal Reserve System
and any other governmental agency having jurisdiction.

     8.5 EXERCISE/PLEDGE. To the extent that a Stock Option Agreement or Stock
Purchase Agreement so provides and if Stock is publicly traded, in the
discretion of the Administrator, upon such terms as the Administrator shall
approve, payment may be made all or in part by the delivery (on a form
prescribed by the Administrator) of an irrevocable direction to pledge shares to
a securities broker or lender approved by the Company, as security for a loan,
and to deliver all or part of the loan proceeds to the Company in payment of all
or part of the Exercise Price and any withholding taxes.

     8.6 WRITTEN NOTICE. The purchaser shall deliver a written notice to the
Administrator requesting that the Company direct the transfer agent to issue to
the purchaser (or to his designee) a certificate for the number of shares of
Common Stock being exercised or purchased or, in the case of a cashless exercise
or share withholding exercise, for any shares that were not sold in the cashless
exercise or withheld.

     8.7 FIRST REFUSAL RIGHT. Each Stock Option Agreement and Stock Purchase
Agreement may provide that the Company shall have the right of first refusal
(the "First Refusal Right"), exercisable in connection with any proposed sale,
hypothecation or other disposition of the Stock purchased by the Optionee or
Offeree pursuant to a Stock Option Agreement or Stock Purchase Agreement; and in
the event the holder of such Stock desires to accept a bona fide third-party
offer for any or all of such Stock, the Stock shall first be offered to the
Company upon the same terms and conditions as are set forth in the bona fide
offer.

     8.8 REPURCHASE RIGHTS. Following a termination of the Participant's Service
the Company may repurchase the Participant's Rights as provided in this Section
8.8.


                                     Page 9
<PAGE>


     8.8.1 REPURCHASE PRICE. Following a termination of the Participant's
Service the Repurchase Right shall be exercisable at a price equal to (i) the
Fair Market Value of vested Stock or, in the case of exercisable options, the
Fair Market Value of the Stock underlying such unexercised options less the
Exercise Price or (ii) the Purchase Price or Exercise Price, as the case may be,
of unvested Stock. The right to repurchase unvested stock as described in
Section 8.8.1(ii) shall lapse at a rate of at least 20% per year over five years
from the date the Right is granted.

     8.8.2 EXERCISE OF REPURCHASE RIGHT. A Repurchase Right may be exercised
only within 90 days after the termination of the Participant's Service for cash
or for cancellation of indebtedness incurred in purchasing the shares.

     8.9 TERMINATION OF REPURCHASE AND FIRST REFUSAL RIGHTS. Each Stock Option
Agreement and Stock Purchase Agreement shall provide that the Repurchase Rights
and First Refusal Rights shall have no effect over, or shall lapse and cease to
have effect over, shares that have been registered under a then currently
effective registration statement under applicable federal or state securities
laws, or when a determination is made by counsel for the Company that such
Repurchase Rights and First Refusal Rights are not required in the circumstances
under applicable federal or state securities laws.

     8.10 NO TRANSFERABILITY. Except as provided herein, a Participant may not
assign, sell or transfer Rights, in whole or in part, other than by will or by
operation of the laws of descent and distribution.

     8.10.1 PERMITTED TRANSFER OF NON-QUALIFIEDOPTION. The Administrator, in its
sole discretion may permit the transfer of a NON-QUALIFIEDOption (but not an ISO
or Stock Purchase Rights) to (i) a member of the Participant's immediate family
or (ii) a trust providing that the Option is to be passed to beneficiaries upon
death of the the trustor (either or both (i) or (ii) referred to as a "PERMITTED
TRANSFEREE"). For purposes of this Section 8.10.1, "immediate family" shall mean
the Optionee's spouse (including a former spouse subject to terms of a domestic
relations order); child, stepchild, grandchild, child-in-law; parent,
stepparent, grandparent, parent-in-law; sibling and sibling-in-law, and shall
include adoptive relationships.

     8.10.2 CONDITIONS OF PERMITTED TRANSFER. A transfer permitted under this
Section 8.9 hereof may be made only upon written notice to and approval thereof
by Administrator. A Permitted Transferee may not further assign, sell or
transfer the transferred Option, in whole or in part, other than by will or by
operation of the laws of descent and distribution. A Permitted Transferee shall
agree in writing to be bound by the provisions of this Plan.

                   SECTION 9: ADJUSTMENTS; MARKET STAND-OFF

     9.1 EFFECT OF CERTAIN CHANGES.

     9.1.1 STOCK DIVIDENDS, SPLITS, ETC. If there is any change in the number of
outstanding shares of Stock by reason of a stock split, reverse stock split,
stock dividend, recapitalization, combination or reclassification, then (i) the
number of shares of Stock available for Rights, (ii) the number of shares of
Stock covered by outstanding Rights and (iii) the Exercise Price or Purchase
Price of any Stock Option or Purchase Right, in effect prior to such change,
shall be


                                    Page 10
<PAGE>


proportionately adjusted by the Administrator to reflect any increase or
decrease in the number of issued shares of Stock; PROVIDED, HOWEVER, that any
fractional shares resulting from the adjustment shall be eliminated.

     9.1.2 LIQUIDATION, DISSOLUTION, MERGER OR CONSOLIDATION. In the event of: a
dissolution or liquidation of the Company, or any corporate separation or
division, including, but not limited to, a split-up, a split-off or a spin-off,
or a sale of substantially all of the assets of the Company; a merger or
consolidation in which the Company is not the surviving corporation; or a
reverse merger in which the Company is the surviving corporation, but the shares
of Company stock outstanding immediately preceding the merger are converted by
virtue of the merger into other property, whether in the form of securities,
cash or otherwise, then, the Company, to the extent permitted by applicable law,
but otherwise in its sole discretion may provide for: (i) the continuation of
outstanding Rights by the Company (if the Company is the surviving corporation);
(ii) the assumption of the Plan and such outstanding Rights by the surviving
corporation or its parent; (iii) the substitution by the surviving corporation
or its parent of Rights with substantially the same terms for such outstanding
Rights; or (iv) the cancellation of such outstanding Rights without payment of
any consideration, provided that if such Rights would be canceled in accordance
with the foregoing, the Participant shall have the right, exercisable during the
later of the ten-day period ending on the fifth day prior to such merger or
consolidation or ten days after the Administrator provides the Rights holder a
notice of cancellation, to exercise such Right in whole or in part without
regard to any installment exercise provisions in the Right agreement.

     9.1.3 ACCELERATED VESTING AND EXERCISABILITY. Unless the applicable Stock
Purchase Agreement or Stock Option Agreement provides otherwise, any right to
repurchase a Purchaser's shares at the original Purchase Price (if any) upon
termination of the Purchaser's Service shall lapse and all of such Stock shall
become vested and all of such Options shall become exercisable in full if (i)
the Company consummates a Change in Control before the Purchaser's Service
terminates and (ii) the options are not assumed by, or Repurchase Right is not
assigned to, the entity that employs the Participant immediately after the
Change in Control or to its parent or subsidiary.

     9.1.4 PAR VALUE CHANGES. In the event of a change in the Stock of the
Company as presently constituted which is limited to a change of all of its
authorized shares with par value, into the same number of shares without par
value, or a change in the par value, the shares resulting from any such change
shall be "Stock" within the meaning of the Plan.

     9.2 DECISION OF ADMINISTRATOR FINAL. To the extent that the foregoing
adjustments relate to stock or securities of the Company, such adjustments shall
be made by the Administrator, whose determination in that respect shall be
final, binding and conclusive; PROVIDED, HOWEVER, that each ISO granted pursuant
to the Plan shall not be adjusted in a manner that causes such Stock Option to
fail to continue to qualify as an ISO without the prior consent of the Optionee
thereof.

     9.3 NO OTHER RIGHTS. Except as hereinbefore expressly provided in this
Section 9, no Participant shall have any rights by reason of any subdivision or
consolidation of shares of Company stock or the payment of any dividend or any
other increase or decrease in the number of shares of Company stock of any class
or by reason of any of the events described in Section 9.1, above, or any other
issue by the Company of shares of stock of any class, or securities convertible
into shares of stock of any class; and, except as provided in this Section 9,
none of the foregoing events shall


                                    Page 11
<PAGE>


affect, and no adjustment by reason thereof shall be made with respect to, the
number or price of shares of Stock subject to Rights. The grant of a Right
pursuant to the Plan shall not affect in any way the right or power of the
Company to make adjustments, reclassifications, reorganizations or changes of
its capital or business structures or to merge or to consolidate or to dissolve,
liquidate or sell, or transfer all or part of its business or assets.

     9.4 MARKET STAND-OFF. Each Stock Option Agreement and Stock Purchase
Agreement shall provide that, in connection with any underwritten public
offering by the Company of its equity securities pursuant to an effective
registration statement filed under the Securities Act of 1933, as amended,
including the Company's initial public offering, the Participant shall agree not
to sell, make any short sale of, loan, hypothecate, pledge, grant any option for
the repurchase of, or otherwise dispose or transfer for value or otherwise agree
to engage in any of the foregoing transactions with respect to any Stock without
the prior written consent of the Company or its underwriters, for such period of
time from and after the effective date of such registration statement as may be
requested by the Company or such underwriters (the "Market Stand-Off").

                     SECTION 10: AMENDMENT AND TERMINATION

     The Board may amend, suspend or terminate the Plan at any time and for any
reason. At the time of such amendment, the Board shall determine, upon advice
from counsel, whether such amendment will be contingent on shareholder approval.

                        SECTION 11: GENERAL PROVISIONS

     11.1 GENERAL RESTRICTIONS.

     11.1.1 NO VIEW TO DISTRIBUTE. The Administrator may require each person
acquiring shares of Stock pursuant to the Plan to represent to and agree with
the Company in writing that such person is acquiring the shares without a view
towards distribution thereof. The certificates for such shares may include any
legend that the Administrator deems appropriate to reflect any restrictions on
transfer.

     11.1.2 LEGENDS. All certificates for shares of Stock delivered under the
Plan shall be subject to such stop transfer orders and other restrictions as the
Administrator may deem advisable under the rules, regulations and other
requirements of the Securities and Exchange Commission, any stock exchange upon
which the Stock is then listed and any applicable federal or state securities
laws, and the Administrator may cause a legend or legends to be put on any such
certificates to make appropriate reference to such restrictions.

     11.1.3 NO RIGHTS AS SHAREHOLDER. Except as specifically provided in this
Plan, a Participant or a transferee of a Right shall have no rights as a
shareholder with respect to any shares covered by the Rights until the date of
the issuance of a Stock certificate to him or her for such shares, and no
adjustment shall be made for dividends (ordinary or extraordinary, whether in
cash, securities or other property) or distributions of other rights for which
the record date is prior to the date such Stock certificate is issued, except as
provided in Section 9.1, hereof.

     11.2 OTHER COMPENSATION ARRANGEMENTS. Nothing contained in this Plan shall
prevent the Board from adopting other or additional compensation arrangements,
subject to shareholder


                                    Page 12
<PAGE>


approval if such approval is required; and such arrangements may be either
generally applicable or applicable only in specific cases.

     11.3 DISQUALIFYING DISPOSITIONS. Any Participant who shall make a
"DISPOSITION" (as defined in Section 424 of the Code) of all or any portion of
an ISO within two years from the date of grant of such ISO or within one year
after the issuance of the shares of Stock acquired upon exercise of such ISO
shall be required to immediately advise the Company in writing as to the
occurrence of the sale and the price realized upon the sale of such shares of
Stock.

     11.4 REGULATORY MATTERS. Each Stock Option Agreement and Stock Purchase
Agreement shall provide that no shares shall be purchased or sold thereunder
unless and until (i) any then applicable requirements of state or federal laws
and regulatory agencies shall have been fully complied with to the satisfaction
of the Company and its counsel and (ii) if required to do so by the Company, the
Optionee or Offeree shall have executed and delivered to the Company a letter of
investment intent in such form and containing such provisions as the Board or
Committee may require.

     11.5 RECAPITALIZATIONS. Each Stock Option Agreement and Stock Purchase
