            NON-QUALIFIED STOCK OPTION AND STOCK REPURCHASE AGREEMENT
                              TERMS AND CONDITIONS

       1. GRANT UNDER 1996 STOCK PLAN. This option is granted pursuant to and is
governed by the Company's 1996 Stock Plan, as amended on August 8, 1997, August
13, 1998, March 3, 1999, September 1, 1999 and February 18, 2000 (the "Plan")
and, unless the context otherwise requires, terms used herein shall have the
same meaning as in the Plan. Determinations made in connection with this option
pursuant to the Plan shall be governed by the Plan as it exists on this date.

       2. GRANT AS NON-QUALIFIED OPTION; OTHER OPTIONS. This option shall be
treated for federal income tax purposes as a Non-Qualified Option and is not
intended to qualify as an incentive stock option under Section 422 of the
Internal Revenue Code of 1986, as amended, and the regulations thereunder (the
"Code"). This option is in addition to any other options heretofore or hereafter
granted to the Optionee by the Company or any Related Corporation (as defined in
the Plan), but a duplicate original of this instrument shall not effect the
grant of another option.

       3.    VESTING OF OPTION IF BUSINESS RELATIONSHIP CONTINUES.
             ----------------------------------------------------

         (a) FULL EXERCISABILITY. Subject to Sections 4 and 5 hereof, this
option may be exercised at any time and from time to time for all or any portion
of the Option Shares, except that this option may not be exercised for a
fraction of a share.

         (b) VESTING. If the Optionee has continued to serve the Company or any
Related Corporation in the capacity of an employee, officer, director or
consultant (such service is described herein as maintaining or being involved in
a "Business Relationship with the Company") through the vesting dates specified
below, Unvested Shares shall become Vested Shares (or shall "VEST") on such
dates in an amount equal to the number of Option Shares set forth opposite the
applicable date:

              Less than one year from                   -   0 Option Shares
               the Vesting Start Date

              One year from                             -   25% of
              the Vesting Start Date (the                   the Option Shares
              "Anniversary Date")

              Every month after the Anniversary Date    -   an additional
              (E.G., if the Anniversary Date is             2.0833% of

                                       2

<PAGE>   3

              August 10, then on the 10th day of each   the Option Shares
              month thereafter; if the Anniversary
              Date is on a day of the month for which
              there is no corresponding day in a
              given month, then on the last day of
              such month) up to and including the
              35th month after the Anniversary Date)

              The 36th month after the Anniversary     The balance of the Option
              Date                                     Shares

Option Shares shall be called "UNVESTED SHARES" and, when issued, shall be
subject to the Company's Repurchase Option described in Section 6 unless and
until they become "VESTED SHARES" in accordance with the vesting schedule set
forth above (at which time such Repurchase Option shall terminate as to such
Vested Shares). Any vesting of Option Shares under this option shall first be
deemed to apply to shares issued upon exercise of this option (in the order of
such exercise) and then to unissued shares subject to this option; and any
exercise of this option shall be deemed to apply first to any then unissued
Vested Shares. The term "OPTION SHARES" used without reference to either
Unvested Shares or Vested Shares shall mean both Unvested Shares and Vested
Shares, without distinction.

         In addition, in the event the Company's Repurchase Option is triggered
pursuant to Section 6 below, and the Company elects not to exercise its option
for the repurchase of any or all of the Unvested Shares, then upon the
expiration of the Repurchase Option Period, any and all Option Shares not
repurchased by the Company shall become Vested Shares.

              (c) VESTING ON SALE. Notwithstanding the foregoing, upon the
consummation of a Sale of the Company (as defined below), 50% of the Option
Shares which remain Unvested Shares at the time of the consummation of such Sale
of the Company shall immediately become Vested Shares, and the remaining
Unvested Shares (the "Remaining Unvested Shares") shall continue to vest at the
rate set forth in Subsection 3(b) hereof (providing that for purposes of this
Subsection, "Option Shares," as used in Subsection 3(b), shall mean the number
of Option Shares set forth on the Cover Sheet to this Agreement), beginning with
the first such date following the consummation of such Sale of the Company on
which Option Shares would have continued to vest had there not been a Sale of
the Company, and PROVIDED FURTHER that all of the Remaining Unvested Shares
shall become Vested Shares (i) at the time of the consummation of the Sale of
the Company if, at or prior to the Sale of the Company, the Optionee is not
offered employment by the successor to the Company (1) at the same or higher
total

                                       3
<PAGE>   4

compensation level than in effect for the Optionee as an employee of the
Company prior to the Sale of the Company, (2) consisting of responsibilities not
materially reduced from the level of responsibilities undertaken by the Optionee
as an employee of the Company prior to the Sale of the Company, and (3) within a
40-mile radius of the Company's principal offices prior to the Sale of the
Company (except for business travel consistent with Optionee's responsibilities
as an employee of the Company), or (ii) if the Optionee is offered and accepts
employment meeting the criteria set forth in clause (i) of this sentence but,
within the 12 months following the Sale of the Company, (1) the Optionee's total
compensation level is reduced below the total compensation in effect for the
Optionee as an employee of the Company prior to the Sale of the Company, (2) the
Optionee's responsibilities are materially reduced below the level of
responsibilities the Optionee had as an employee of the Company prior to the
Sale of the Company, (3) the Optionee is transferred by the successor to the
Company (the "New Employer") to a location beyond a 40-mile radius of the
Company's principal offices prior to the Sale of the Company (except for
business travel consistent with Optionee's responsibilities as an employee of
the New Employer), or (4) the Optionee's employment with the New Employer is
terminated by the New Employer without Cause, at the time of the happening of
any event enumerated in this clause (ii).

         For purposes of the foregoing, "Sale of the Company" shall mean (i) the
sale by the Company of all, or substantially all, of its assets; (ii) the sale
by Company shareholders of greater than 50% of the stock of the Company in a
single transaction or a group of related transactions; or, (iii) the merger or
consolidation of the Company with, or into, another company where the
outstanding shares of the Company immediately prior to such merger or
consolidation represent or are converted into or exchanged for securities which
represent less than 50% of the voting power of the surviving or resulting
entity.

         For purposes of the foregoing, "Cause" shall mean a material violation
by the Optionee that is not cured within a reasonable time after written notice
thereof of any noncompetition agreement between the Optionee and the New
Employer or any of its subsidiaries or a finding in a criminal proceeding that
the Optionee has committed felonious criminal misconduct in connection with the
Optionee's employment by the New Employer, which misconduct has been materially
injurious to the interests of the New Employer. Further, and without limiting
the generality of the foregoing, the following circumstances shall be deemed not
to involve the voluntary resignation by a Optionee or a termination by the New
Employer for Cause: (i) the death of the Optionee, (ii) the disability or
incapacity of the Optionee which prevents the Optionee from continuing his
employment with the New Employer, in Optionee's then-current capacity, or (iii)
the resignation of the Optionee within 30 days of a vote of the board of
directors of the New Employer to remove a Optionee from his then-current office
(other than for Cause).

                  (d) OTHER ACCELERATION.  Notwithstanding the foregoing, in
accordance with and subject to the provisions of the Plan, the Committee may,
in its

                                       4
<PAGE>   5

discretion, accelerate the date that any Unvested Shares become Vested
Shares under this Option.

         The foregoing rights are cumulative and (subject to Sections 4 or 5
hereof if the Optionee ceases to maintain a Business Relationship with the
Company and all Related Corporations) may be exercised up to and including the
date which is ten years from the date this option is granted.

                  (e) PARTIAL EXERCISE. This option may be exercised in part at
any time and from time to time within the above limits, except that this option
may not be exercised for a fraction of a share unless such exercise is with
respect to the final installment of stock subject to this option and cash in
lieu of a fractional share must be paid, in accordance with Paragraph 13(G) of
the Plan, to permit the Optionee to exercise completely such final installment.
Any fractional share with respect to which an installment of this option cannot
be exercised because of the limitation contained in the preceding sentence shall
remain subject to this option and shall be available for later purchase by the
Optionee in accordance with the terms hereof.

       4. TERMINATION OF BUSINESS RELATIONSHIP. If the Optionee's Business
Relationship with the Company and all Related Corporations is terminated, other
than by reason of death, disability or dissolution as defined in Section 5,
vesting of Unvested Shares shall immediately cease, this option may be exercised
only as to any Option Shares that are Vested Shares on the date of termination
of the Optionee's Business Relationship and this option shall terminate (and may
no longer be exercised) after the passage of 90 days after the date of
termination of the Optionee's Business Relationship (but in no event later than
the scheduled expiration date). In the event of termination the Optionee's
Business Relationship with the Company, the Repurchase Option described in
Section 6 shall also be applicable and Optionee's only rights hereunder shall be
those which are properly exercised before the termination of this option
(subject to Section 6).

       5.     DEATH; DISABILITY; DISSOLUTION.

         (a) DEATH. If the Optionee is a natural person who dies while in a
Business Relationship with the Company, vesting of Unvested Shares shall
immediately cease. In such event, this option may be exercised only as to any
Option Shares that are Vested Shares on the date of the Optionee's death, by the
Optionee's estate, personal representative or beneficiary to whom this option
has been transferred or assigned pursuant to Section 10, and this option may be
exercised only on or prior to the date which is 180 days after the date of death
(but not later than the scheduled expiration date). In the event of death, the
Repurchase Option described in Section 6 shall also be applicable.

                                       5
<PAGE>   6

            (b) DISABILITY. If the Optionee is a natural person that ceases to
maintain a Business Relationship with the Company by reason of his or her
disability, vesting of Unvested Shares shall immediately cease. In such event,
this option may be exercised only as to any Option Shares that are Vested Shares
on the date of termination of the Optionee's Business Relationship with the
Company; and this option may be exercised only on or prior to the date which is
180 days after the date of termination of the Optionee's Business Relationship
with the Company (but not later than the scheduled expiration date). In the
event of such termination of the Optionee's Business Relationship with the
Company, the Repurchase Option described in Section 6 shall also be applicable.
For purposes hereof, "DISABILITY" means "PERMANENT AND TOTAL DISABILITY" as
defined in Section 22(e)(3) of the Code.

              (c) EFFECT OF TERMINATION. At the expiration of such 180-day
period provided in paragraph (a) or (b) of this Section 5 or the scheduled
expiration date, whichever is the earlier, this option shall terminate (and
shall no longer be exercisable) and the only rights hereunder shall be those as
to which the option was properly exercised before such termination (subject to
Section 6 hereof).

              (d) DISSOLUTION. If the Optionee is a corporation, partnership,
trust or other entity that is dissolved, is liquidated, becomes insolvent or
enters into a merger or acquisition with respect to which the Optionee is not
the surviving entity, at a time when the Optionee is involved in a Business
Relationship with the Company, this option shall immediately terminate as of the
date of such event (and shall thereafter not be exercisable to any extent
whatsoever), and the only rights hereunder shall be those as to which this
option was properly exercised before such dissolution or other event (subject to
Section 6 hereof).

         6. REPURCHASE OPTION. In the event of any voluntary or involuntary
termination of the Optionee's Business Relationship by the Company for any or no
reason, including by reason of death or disability, the Company shall, upon and
from the date of such termination (as reasonably fixed and determined by the
Company) have an irrevocable, exclusive, assignable option (the "REPURCHASE
OPTION") for a period of ninety (90) days (the "REPURCHASE OPTION PERIOD") to
repurchase all or any portion of the Optionee's Unvested Shares at the original
purchase price per share paid by the Optionee. Such option may be exercised by
the Company by sending written notice to the Optionee, which notice shall
specify the number of Unvested Shares being so repurchased and which notice
shall be accompanied by the Company's check for the purchase price of those
shares. Upon the sending of such notice and payment, the Company shall become
the legal and beneficial owner of the Unvested Shares being repurchased and all
rights and interests therein or relating thereto, and the Company shall have the
right to retain and transfer to its own name the number of Unvested Shares being
repurchased by the Company. Upon exercise of the Repurchase Option in the manner
provided in this Section 6, if the Company does not have possession of the
certificate or certificates representing the Unvested Shares being repurchased,
the

                                       6
<PAGE>   7

Optionee shall deliver to the Company, within ten (10) days of receipt of
the Company's notice of such repurchase, such certificate or certificates duly
endorsed and free and clear of any and all liens, charges and encumbrances. If
the Company does have possession of such certificate or certificates pursuant to
Section 18 hereof, it may use the Optionee's stock assignment to effectuate the
repurchase.

       7.     PAYMENT OF PRICE:

              (a)    FORM OF PAYMENT.  The option price shall be paid in the
following manner:

                  (i)   in cash or by check;

                 (ii)   subject to paragraph 7(b) below, by delivery of shares
                        of the Company's Common Stock having a fair market value
                        (as determined by the Committee) equal as of the date of
                        exercise to the option price;

                (iii)   by delivery of an assignment satisfactory in form and
                        substance to the Company of a sufficient amount of the
                        proceeds from the sale of the Option Shares and an
                        instruction to the broker or selling agent to pay that
                        amount to the Company; or

                 (iv)   by any combination of the foregoing.

              (b) LIMITATIONS ON PAYMENT BY DELIVERY OF COMMON STOCK. If the
Optionee delivers Common Stock held by the Optionee ("Old Stock") to the Company
in full or partial payment of the option price, and the Old Stock so delivered
is subject to restrictions or limitations imposed by agreement between the
Optionee and the Company, an equivalent number of Option Shares shall be subject
to all restrictions and limitations applicable to the Old Stock to the extent
that the Optionee paid for the Option Shares by delivery of Old Stock, in
addition to any restrictions or limitations imposed by this Agreement.
Notwithstanding the foregoing, the Optionee may not pay any part of the exercise
price hereof by transferring Common Stock to the Company unless such Common
Stock has been owned by the Optionee free of any substantial risk of forfeiture
for at least six months.

       8. RESTRICTIONS ON TRANSFER. The Optionee agrees not to sell, assign,
transfer, pledge, hypothecate, gift, mortgage or otherwise encumber or dispose
of (except to the Company or any successor to the Company) all or any Unvested
Shares or any interest therein, and any Unvested Shares purchased upon exercise
of this option shall be held in escrow by the Company in accordance with the
terms of Section 18 below unless and until they become Vested Shares. Option
Shares will be of an illiquid nature and will be

                                       7
<PAGE>   8

deemed to be "restricted securities" for purposes of the Securities Act of
1933, as amended. Accordingly, such shares must be sold in compliance with the
registration requirements of such Act or an exemption therefrom. Certificates
representing the Option Shares shall bear the Securities Exchange Act of 1934
legend and legends which state the restrictions imposed upon the Option Shares
as set forth in this Agreement.

       9. METHOD OF EXERCISING OPTION. Subject to the terms and conditions of
this Agreement, this option may be exercised by written notice to the Company,
at the principal executive office of the Company, or to such transfer agent as
the Company shall designate. Such notice shall state the election to exercise
this option and the number of Option Shares for which it is being exercised and
shall be signed by the person or persons so exercising this option. Such notice
shall be accompanied by payment of the full purchase price of such shares, and
the Company shall deliver a certificate or certificates representing such shares
as soon as practicable after the notice shall be received. Such certificate or
certificates shall be registered in the name of the person or persons so
exercising this option (or, if this option shall be exercised by the Optionee
and if the Optionee shall so request in the notice exercising this option, shall
be registered in the name of the Optionee and another person jointly, with right
of survivorship). In the event this option shall be exercised, pursuant to
Section 5 hereof, by any person or persons other than the Optionee, such notice
shall be accompanied by appropriate proof of the right of such person or persons
to exercise this option.

     10. OPTION NOT TRANSFERABLE. This option is not transferable or assignable
except by will or by the laws of descent and distribution or pursuant to a valid
domestic relations order. Except as set forth in the preceding sentence, during
the Optionee's lifetime, only the Optionee can exercise this option.

     11. NO OBLIGATION TO EXERCISE OPTION. The grant and acceptance of this
option imposes no obligation on the Optionee to exercise it.

     12. NO OBLIGATION TO CONTINUE BUSINESS RELATIONSHIP. Neither the Plan, this
Agreement, nor the grant of this option imposes any obligation on the Company or
any Related Corporation to continue to maintain a Business Relationship with the
Optionee.

     13. NO RIGHTS AS STOCKHOLDER UNTIL EXERCISE. The Optionee shall have no
rights as a stockholder with respect to the Option Shares until such time as the
Optionee has exercised this option by delivering a notice of exercise and has
paid in full the purchase price for the number of shares for which this option
is to be so exercised in accordance with Section 9. Except as is expressly
provided in the Plan with respect to certain

                                       8
<PAGE>   9

changes in the capitalization of the Company, no adjustment shall be made
for dividends or similar rights for which the record date is prior to such date
of exercise.

      14. CAPITAL CHANGES AND BUSINESS SUCCESSIONS. The Plan contains provisions
covering the treatment of options in a number of contingencies such as stock
splits and mergers. Provisions in the Plan for adjustment with respect to stock
subject to options and the related provisions with respect to successors to the
business of the Company are hereby made applicable hereunder and are
incorporated herein by reference.

      15.     WITHHOLDING TAXES; 83(b) ELECTION:

              (a) WITHHOLDING TAXES. If the Company or any Related Corporation
in its discretion determines that it is obligated to withhold any tax in
connection with the exercise of this option, or in connection with the transfer
of, or the lapse of restrictions on, any Common Stock or other property acquired
pursuant to this option, the Optionee hereby agrees that the Company or any
Related Corporation may withhold from the Optionee's wages or other remuneration
the appropriate amount of tax. At the discretion of the Company or Related
Corporation, the amount required to be withheld may be withheld in cash from
such wages or other remuneration or in kind from the Common Stock or other
property otherwise deliverable to the Optionee on exercise of this option. The
Optionee further agrees that, if the Company or Related Corporation does not
withhold an amount from the Optionee's wages or other remuneration sufficient to
satisfy the withholding obligation of the Company or Related Corporation, the
Optionee will make reimbursement on demand, in cash, for the amount
underwithheld.

THE FILING OF AN ELECTION UNDER SECTION 83(b) OF THE INTERNAL REVENUE CODE OF
1986, AS AMENDED, MAY BE REQUIRED BY SECTION 15(b) OF THIS AGREEMENT. IF
REQUIRED, SUCH AN ELECTION MUST BE FILED WITH THE INTERNAL REVENUE SERVICE
WITHIN 30 DAYS FOLLOWING EACH EXERCISE OF THIS OPTION.

              (b) SECTION 83(b) ELECTION. Optionee acknowledges that the
Unvested Shares acquired upon exercise of this option may be treated as subject
to a substantial risk of forfeiture within the meaning of Section 83 of the Code
and that, in the absence of an election under Section 83(b) of the Code, such
treatment could delay the determination of the tax consequences of such exercise
for both the Company and Optionee. In order to ensure that the tax consequences
of such exercise will be determined at the time of exercise, Optionee agrees to
file a timely election under Section 83(b) of the Code to include in Optionee's
taxable income, at the time of exercise, the difference between the fair market
value of the Unvested Shares received upon exercise of this option and the
amount paid for such shares; provided, however, that the Board, in its sole and
absolute discretion, may waive the requirement that the Optionee file such
election.

      16.     COMPANY'S RIGHT OF FIRST REFUSAL:

              (a) EXERCISE OF RIGHT. If the Optionee or his or her legal
representative (the "Transferor") desires to transfer all or any part of the
Option Shares to any person other than the Company (an "Offeror"), the
Transferor shall: (i) obtain in writing an irrevocable and unconditional bona
fide offer (the "Offer") for the purchase thereof from the Offeror; and (ii)
give written notice (the "Option Notice") to the Company setting forth the
Optionee's desire to transfer such shares, which Option Notice shall be
accompanied by a photocopy of the Offer and shall set forth at least the name
and address of the Offeror and the price and terms of the bona fide offer. Upon
receipt of the Option Notice, the Company shall have an assignable option to
purchase any or all of such shares (the "Company Option Shares") specified in
the Option Notice, such option to be exercisable by giving, within 30 days after
receipt of the Option Notice, a written counter-notice to the Transferor. If the
Company elects to purchase any or all of such Company Option Shares, it shall be
obligated to purchase, and the Transferor shall be obligated to sell to the
Company, such Company Option Shares at the price and terms indicated in the
Offer within 30 days from the date of delivery by the Company of such
counter-notice.

              (b) SALE OF OPTION SHARES TO OFFEROR. The Transferor may, for 60
days after the expiration of the 30-day period during which the Company may give
the counter-notice, sell, pursuant to the terms of the Offer, any or all of such
Company Option Shares not purchased or agreed to be purchased by the Company or
its assignee; PROVIDED, HOWEVER, that the Transferor shall not sell such Company
Option Shares to the Offeror if the Offeror is a competitor of the Company and
the Company gives written notice to the Transferor, within 30 days of its
receipt of the Option Notice, stating that the Transferor shall not sell such
Company Option Shares to such Offeror; and PROVIDED, FURTHER, that prior to the
sale of such Company Option Shares to the Offeror, the Offeror shall execute an
agreement with the Company pursuant to which the Offeror agrees to be subject to
the restrictions set forth in this Agreement. If any or all of such Company
Option Shares are not sold pursuant to an Offer within the time permitted above,
the unsold Company Option Shares shall remain subject to the terms of this
Section 16.

              (c) ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE. If there shall
be any change in the Common Stock of the Company through merger, consolidation,
reorganization, recapitalization, stock dividend, stock split, combination or
exchange of shares, or the like, the restrictions contained in Section 8 or this
Section 16 shall apply with equal force to additional and/or substitute
securities, if any, received by the Optionee in exchange for, or by virtue of
his or her ownership of, Company Option Shares, except as otherwise determined
by the Board of Directors of the Company.

              (d) FAILURE TO DELIVER COMPANY OPTION SHARES: If the Transferor
fails or refuses to deliver on a timely basis duly endorsed certificates
representing Company Option Shares to be sold to the Company or its assignee
pursuant to this Section 16, the Company shall have the right to deposit the
purchase price for such Company Option

<PAGE>   11

Shares in a special account with any bank or trust company in the State of
Delaware, giving notice of such deposit to the Transferor, whereupon such
Company Option Shares shall be deemed to have been purchased by the Company. All
such monies shall be held by the bank or trust company for the benefit of the
Transferor. All monies deposited with the bank or trust company remaining
unclaimed for two years after the date of deposit shall be repaid by the bank or
trust company to the Company on demand, and the Transferor shall thereafter look
only to the Company for payment. The Company may place a legend on any stock
certificate delivered to the Transferor reflecting the restrictions on transfer
provided in Section 8 hereof and this Section 16.

              (e) EXPIRATION OF COMPANY'S RIGHT OF FIRST REFUSAL AND TRANSFER
RESTRICTIONS: The first refusal rights of the Company and the transfer
restrictions set forth above shall remain in effect until such time, if ever, as
a distribution to the public is made of shares of the Company's Common Stock
pursuant to a registration statement filed under the Securities Act of 1933, as
amended, or a successor statute, at which time the first refusal rights of the
Company and the transfer restrictions set forth herein will automatically
expire.

      17. LOCK-UP AGREEMENT. The Optionee agrees that in connection with an
underwritten public offering of Common Stock, upon the request of the Company or
the principal underwriter managing such public offering, this Option and the
Option Shares may not be sold, offered for sale or otherwise disposed of without
the prior written consent of the Company or such underwriter, as the case may
be, for at least 180 days after the effectiveness of the Registration Statement
filed in connection with such offering, or such longer period of time as the
Board of Directors may determine if all of the Company's directors and officers
agree to be similarly bound. The lock-up agreement established pursuant to this
paragraph 17 shall have perpetual duration, except with respect to those Options
or Option Shares which are sold pursuant to Rule 701, Rule 144 or similar
exemption.

       18. ESCROW OF UNVESTED SHARES.

                  (a) If this option is exercised as to any Unvested Shares,
such Unvested Shares shall be issued in the name of the Optionee, but shall be
held in escrow by the Company, acting in the capacity of escrow agent, together
with a stock assignment executed by the Optionee with respect to such Unvested
Shares.

                  (b) With respect to any Unvested Shares held in escrow that
become Vested Shares, the Company shall promptly issue a new certificate for the
number of shares that have become Vested Shares and shall deliver such
certificate to the Optionee and shall retain in escrow a new certificate for any
remaining Unvested Shares in exchange for the all or the relevant portion of the
applicable certificate then being held by the Company as escrow agent.

                                       11
<PAGE>   12

                  (c) Subject to the terms hereof, the Optionee shall have all
the rights of a shareholder with respect to the Unvested Shares while they are
held in escrow, including, without limitation, the right to vote the Unvested
Shares and receive any cash dividends declared thereon.

                  (d) The Company may terminate this escrow at any time. The
Company may also appoint another entity to serve as escrow agent hereunder, in
which event the Optionee agrees to execute all documents requested by the
Company in connection therewith.

      19. PROVISION OF DOCUMENTATION TO OPTIONEE. By signing this Agreement the
Optionee acknowledges receipt of a copy of this Agreement and a copy of the
Plan.

                  (c) The Company shall provide the Stockholders with 30 days'

of Series C Preferred, the Company shall provide to HarbourVest copies of all
notices, reports, materials, minutes, contracts and other documents, at the same
time and in the same manner as such documents are provided to the Board of
Directors of the Company, unless and to the extent (after consultation with
counsel) the Company shall determine that delivery of such notice and/or
materials to HarbourVest may violate attorney-client privilege or other

any action, suit or proceeding with respect to which he may be entitled to
indemnification by the Company pursuant to its Certificate of Incorporation or
By-laws, or otherwise, he shall be entitled to be represented in such action,
suit or proceeding by counsel of his choice and the reasonable expenses of such
representation shall be reimbursed by the Company to the extent provided in or
authorized by said Certificate of Incorporation or By-laws. Each Stockholder
agrees not to take any action to amend any provisions of the Certificate of
Incorporation or By-laws of the Company relating to indemnification of
directors, as presently in effect, without the prior written consent of all of
the Stockholders.

         4. Restrictive Legend. All certificates representing Voting Shares
owned or hereafter acquired by the Stockholders or any transferee of the
Stockholders bound by this Agreement shall have affixed thereto a legend

                  subject to certain voting agreements as set forth in an
                  Investor Rights Agreement (as the same may be amended or
                  amended and restated from time to time) by and among the
                  registered owner of this certificate, the corporation and
                  certain other shareholders of the corporation, a copy of which
                  is available for inspection at the office of the Secretary of

<PAGE>   7
         5. Transfers of Voting Rights. Any transferee to whom Voting Shares are
transferred by a Stockholder, whether voluntarily or by operation of law, shall
be bound by the voting obligations imposed upon the transferor under this
Agreement, and shall be entitled to the rights granted to the transferor under
this Agreement, to the same extent as if such transferee were a Stockholder
hereunder.

ARTICLE III.      REGISTRATION RIGHTS

         1.       Required Registrations.

                  (a) At any time after September 13, 2000, any Preferred Holder
or Holders holding at least 25% of the Registrable Shares may request, in
writing, that the Company effect the registration (i) on Form S-1 or Form S-2
(or any successor form) of Registrable Shares owned by such Preferred Holder or
Holders having an aggregate offering price to the public, based on the then
current market price or fair value, of at least (A) $15,000,000, in the event of
an initial public offering, or (B) $10,000,000, in the event of any subsequent
public offering or (ii) on Form S-3 (or any successor form) of Registrable
Shares owned by such Preferred Holder or Holders having an aggregate offering
price of at least $1,000,000 (based on the then current market price or fair
value). If the Preferred Holder or Holders initiating the registration intend(s)
to distribute the Registrable Shares by means of an underwriting, such Preferred
Holder or Holders shall so advise the Company in its request. In the event such
registration is underwritten, the right of other Preferred Holders to
participate in such registration shall be conditioned on such Preferred Holders'
participation in such underwriting. Upon receipt of any such request, the
Company shall promptly give written notice of such proposed registration to all
other Preferred Holders. Such Preferred Holders shall have the right, by giving
written notice to the Company within 30 days after the Company provides its
notice, to elect to have included in such registration such of their Registrable
Shares as such Preferred Holders may request in such notice of election;
provided that if the underwriter (if any) managing the offering determines that,
because of marketing factors, all of the Registrable Shares requested to be
registered by all Preferred Holders may not be included in the offering, then
all Preferred Holders who have requested registration shall participate in the
registration pro rata based upon the number of Registrable Shares which they
have requested to be so registered. Thereupon, the Company shall, as
expeditiously as possible, use its reasonable best efforts to effect the
registration on Form S-1, Form S-2 or Form S-3 (or any successor form) of all
Registrable Shares which the Company has been requested to so register.

                  (b) The Company shall not be required to effect more than two
registrations pursuant to clause (i) of paragraph (a) above; provided, however,
that such obligation shall be deemed satisfied only when a registration
statement covering the applicable Registrable Shares shall have (i) become
effective and, if such method of disposition is a firm commitment underwritten
public offering, all such Registrable Shares have been sold pursuant thereto, or
(ii) been withdrawn at the request of the Preferred Holders requesting such
registration (other than as a result of information

                                       7
<PAGE>   8
concerning the business or financial condition of the Company which is made
known to the Preferred Holders after the date on which such registration was
requested). In addition, the Company shall not be required to effect any
registration within 6 months after the effective date of any other Registration
Statement on Form S-1 or S-3 involving an underwritten offering of the Company.

                  (c) If at the time of any request to register Registrable
Shares pursuant to this Article III, Section 1, the Company is engaged at the
time of the request in a registered public offering of securities for its own
account or is engaged in any other activity which, in the good faith
determination of a majority of the Company's Board of Directors, would be
adversely affected by the requested registration to the material detriment of
the Company, then the Company may at its option direct that such request be
delayed for a period not in excess of 120 days from the effective date of such
request, such right to delay a request to be exercised by the Company not more
than once in any 18-month period.

         2.       Incidental Registration.

                  (a) Whenever the Company proposes to file a Registration
Statement at any time and from time to time, it will, prior to such filing, give
written notice to all Stockholders of its intention to do so and, upon the
written request of a Stockholder or Stockholders given within 30 days after the
Company provides such notice (which request shall state the intended method of
disposition of such Registrable Shares), the Company shall use its reasonable
best efforts to cause all Registrable Shares which the Company has been
requested by such Stockholder or Stockholders to register to be registered under
the Securities Act to the extent necessary to permit their sale or other
disposition in accordance with the intended methods of distribution specified in
the request of such Stockholder or Stockholders; provided, however, that the
Company shall have the right to postpone or withdraw any registration effected
pursuant to this Article III, Section 2 without obligation to any Stockholder.

                  (b) In connection with any registration under this Article
III, Section 2 involving an underwriting, the Company shall not be required to
include any Registrable Shares in such registration unless the holders thereof
accept the terms of the underwriting as agreed upon between the Company and the
underwriters selected by it; provided that the Company shall use commercially
reasonable efforts to ensure that such underwriting agreement shall not provide
for indemnification or contribution obligations on the part of Preferred Holders
greater than the obligations of the Preferred Holders pursuant to Section 5(b)
of this Article III. If in the opinion of the managing underwriter it is
desirable because of marketing factors to limit the number of Registrable Shares
to be included in the offering, then the Company shall be required to include in
the registration only that number of Registrable Shares, if any, which the
managing underwriter believes should be included therein; provided, however,
that no persons or entities other than the Company, the Stockholders and other
persons or entities holding registration rights shall be permitted to include
securities in the offering. If the number of Registrable Shares to

                                       8
<PAGE>   9
be included in the offering in accordance with the foregoing is less than the
total number of shares which the holders of Registrable Shares have requested to
be included, then the holders of Registrable Shares who have requested
registration and other holders of securities entitled to include them in such
registration shall participate in the registration pro rata based upon their
total ownership of shares of Common Stock (giving effect to the conversion into
Common Stock of all securities convertible there into). If any holder would thus
be entitled to include more securities than such holder requested to be
registered, the excess shall be allocated among other requesting holders pro
rata in the manner described in the preceding sentence.

         3. Registration Procedures. If and whenever the Company is required by
the provisions of this Agreement to use its reasonable best efforts to effect
the registration of any of the Registrable Shares under the Securities Act, the
Company shall:

                  (a) File with the Commission a Registration Statement with
respect to such Registrable Shares and use its reasonable best efforts to cause
that Registration Statement to become and remain effective;

                  (b) As expeditiously as possible prepare and file with the
Commission any amendments and supplements to the Registration Statement and the
prospectus included in the Registration Statement as may be necessary to keep
the Registration Statement effective, in the case of a firm commitment
underwritten public offering, until each underwriter has completed the
distribution of all securities purchased by it and, in the case of any other
offering, until the earlier of the sale of all Registrable Shares covered
thereby or 120 days after the effective date thereof;

                  (c) As expeditiously as possible furnish to each selling
stockholder such reasonable numbers of copies of the prospectus, including a
preliminary prospectus, in conformity with the requirements of the Securities
Act, and such other documents as the selling Stockholder may reasonably request
in order to facilitate the public sale or other disposition of the Registrable
Shares owned by the selling Stockholder; and

                  (d) As expeditiously as possible use its best efforts to
register or qualify the Registrable Shares covered by the Registration Statement
under the securities or Blue Sky laws of such states as the selling Stockholder
shall reasonably request, and do any and all other acts and things that may be
necessary or desirable to enable the selling Stockholder to consummate the
public sale or other disposition in such states of the Registrable Shares owned
by the selling Stockholder; provided, however, that the Company shall not be
required in connection with this paragraph (d) to qualify as a foreign
corporation or execute a general consent to service of process in any
jurisdiction.

         If the Company has delivered preliminary or final prospectuses to the
selling Stockholder and after having done so the prospectus is amended to comply
with the requirements of the Securities Act, the Company shall promptly notify
the selling Stockholders and, if requested, the selling Stockholder shall
immediately cease making

                                       9
<PAGE>   10
offers of Registrable Shares and return all prospectuses to the Company. The
Company shall promptly provide each selling Stockholder with revised
prospectuses and, following receipt of the revised prospectuses, the selling
Stockholder shall be free to resume making offers of the Registrable Shares.

         4. Allocation of Expenses. The Company will pay all Registration
Expenses (defined below) of all registrations under this Agreement; provided,
however, that if a registration under Article III, Section l(a) (i) is withdrawn
at the request of the Preferred Holder or Holders requesting such registration
(other than as a result of information concerning the business or financial
condition of the Company which is made known to the Preferred Holder or Holders
after the date on which such registration was requested) and if the requesting
Preferred Holder or Holders elect not to have such registration counted as a
registration requested under Article III, Section l(a)(i), the requesting
Preferred Holder or Holders shall pay the Registration Expenses of such
registration pro rata in accordance with the number of their Registrable Shares
included in such registration. For purposes of this Article III, Section 4, the
term "Registration Expenses" shall mean all expenses incurred by the Company in
complying with the provisions of this Article III, including, without
limitation, all registration and filing fees, exchange listing fees, printing
expenses, fees and expenses of counsel for the Company and the fees and expenses
of one counsel selected by the selling Stockholder(s) to represent the selling
Stockholder(s), state Blue Sky fees and expenses, and the expense of any special
audits incident to or required by any such registration, but excluding
underwriting discounts, selling commissions and the fees and expenses of selling
Stockholders' own counsel (other than the one counsel selected to represent all
selling Stockholder(s)).

         5.       Indemnification and Contribution.

                  (a) In the event of any registration of any of the Registrable
Shares under the Securities Act pursuant to this Agreement, the Company will
indemnify and hold harmless the seller of such Registrable Shares (and each of
its officers and directors), each underwriter of such Registrable Shares, and
each other person, if any, who controls such seller (and each of its officers
and directors) or underwriter within the meaning of the Securities Act or the
Exchange Act against any losses, claims, damages or liabilities, joint or
several, to which such seller, underwriter or controlling person may become
subject under the Securities Act, the Exchange Act, state securities or Blue Sky
laws or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon any untrue statement
or alleged untrue statement of any material fact contained in any Registration
Statement under which such Registrable Shares were registered under the
Securities Act, any preliminary prospectus or final prospectus contained in the
Registration Statement, or any amendment or supplement to such Registration
Statement, or arise out of or are based upon the omission or alleged omission to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading or any material violation by the Company of
the Securities Act or any rule or regulation promulgated thereunder applicable
to the

                                       10
<PAGE>   11
Company and relating to action or inaction required of the Company in connection
with any such registration; and the Company will reimburse such seller,
underwriter and each such controlling person for any legal or any other expenses
reasonably incurred by such seller, underwriter or controlling person in
connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company will not be liable in
any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon any untrue statement or omission made in such
Registration Statement, preliminary prospectus or final prospectus, or any such
amendment or supplement, in reliance upon and in conformity with information
furnished to the Company, in writing, by or on behalf of such seller,
underwriter or controlling person specifically for use in the preparation
thereof.

                  (b) In the event of any registration of any of the Registrable
Shares under the Securities Act pursuant to this Agreement, each seller of
Registrable Shares, severally and not jointly, will indemnify and hold harmless
the Company, each of its directors and officers and each underwriter (if any)
and each person, if any, who controls the Company or any such underwriter within
the meaning of the Securities Act or the Exchange Act, against any losses,
claims, damages or liabilities, joint or several, to which the Company, such
directors and officers, underwriter or controlling person may become subject
under the Securities Act, Exchange Act, state securities or Blue Sky laws or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of a material fact contained in any Registration Statement
under which such Registrable Shares were registered under the Securities Act,
any preliminary prospectus or final prospectus contained in the Registration
Statement, or any amendment or supplement to the Registration Statement, or
arise out of or are based upon any omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, if the statement or omission was made in reliance upon
and in conformity with information relating to such seller furnished in writing
to the Company by or on behalf of such seller specifically for use in connection
with the preparation of such Registration Statement, prospectus, amendment or
supplement; provided, however, that the liability of each Stockholder under this
Section 5(b) shall be limited to the proportion of any such loss, claim, damage,
liability or expense which is equal to the proportion that the public offering
price of Shares sold by such seller under such registration statement bears to
the total public offering price under such registration statement of all
securities sold by Stockholders liable hereunder for any such loss, claim,
damage, liability or expense, but in any event the obligations of such
Stockholders hereunder shall be limited to an amount equal to the proceeds to
each Stockholder of Registrable Shares sold in connection with such
registration.

                  (c) Each party entitled to indemnification under this Article
III, Section 5 (the "Indemnified Party") shall give notice to the party required
to provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any
such claim or any litigation resulting

                                       11
<PAGE>   12
therefrom; provided, that counsel for the Indemnifying Party, who shall conduct
the defense of such claim or litigation, shall be approved by the Indemnified
Party (whose approval shall not be unreasonably withheld); and, provided
further, that the failure of any Indemnified Party to give notice as provided
herein shall not relieve the Indemnifying Party of its obligations under this
Article III, Section 5. The Indemnified Party may participate in such defense at
such party's expense; provided, however, that the Indemnifying Party shall pay
such expense if representation of such Indemnified Party by the counsel retained
by the Indemnifying Party would be inappropriate due to actual or potential
differing interests between the Indemnified Party and any other party
represented by such counsel in such proceeding. No Indemnifying Party, in the
defense of any such claim or litigation shall, except with the consent of each
Indemnified Party, consent to entry of any judgment or enter into any settlement
which does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such Indemnified Party of a release from all liability
in respect of such claim or litigation, and no Indemnified Party shall consent
to entry of any judgment or settle such claim or litigation without the prior
written consent of the Indemnifying Party.

                  (d) In order to provide for just and equitable contribution to
joint liability under the Securities Act in any case in which either (i) any
holder of Registrable Shares exercising rights under this Agreement, or any
controlling person of any such holder, makes a claim for indemnification
pursuant to this Article III, Section 5 but it is judicially determined (by the
entry of a final judgment or decree by a court of competent jurisdiction and the
expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that this Article III, Section 5 provides for indemnification in such case, or
(ii) contribution under the Securities Act may be required on the part of any
such selling Stockholder or any such controlling person in circumstances for
which indemnification is provided under this Article III, Section 5; then, in
each such case, the Company and such Stockholder will contribute to the
aggregate losses, claims, damages or liabilities to which they may be subject
(after contribution from others) in such proportions so that such holder is
responsible for the portion represented by the percentage that the public
offering price of its Registrable Shares offered by the Registration Statement
bears to the public offering price of all securities offered by such
Registration Statement, and the Company is responsible for the remaining
portion; provided, however, that, in any such case, (A) no such holder will be
required to contribute any amount in excess of the proceeds to it of all
Registrable Shares sold by it pursuant to such Registration Statement, and (B)
no person or entity guilty of fraudulent misrepresentation, within the meaning
of Section 11(f) of the Securities Act, shall be entitled to contribution from
any person or entity who is not-guilty of such fraudulent misrepresentation.

         6. Indemnification with Respect to Underwritten Offering. In the event
that Registrable Shares are sold pursuant to a Registration Statement in an
underwritten offering pursuant to Article III, Section 1, the Company agrees to
enter into an underwriting agreement containing customary representations and
warranties with respect to the business and operations of an issuer of the
securities being registered and

                                       12
<PAGE>   13
customary covenants and agreements to be performed by such issuer, including
without limitation customary provisions with respect to indemnification by the
Company of the underwriters of such offering.

         7. Information by Holder. Each Stockholder including Registrable Shares
in any registration shall furnish to the Company such information regarding such
Stockholder and the distribution proposed by such Stockholder as the Company may
reasonably request in writing and as shall be required in connection with any
registration, qualification or compliance referred to in this Agreement.

         8. "Stand-Off" Agreement. Each Stockholder, if requested by the Company
and the managing underwriter of an offering by the Company of Common Stock or
other securities of the Company pursuant to a Registration Statement, shall
agree not to sell publicly or otherwise transfer or dispose of any Registrable
Shares or other securities of the Company held by such Stockholder for a
specified period of time (not to exceed 180 days) following the effective date
of such Registration Statement; provided, that:

                  (a) such agreement shall only apply to the first Registration
Statement covering Common Stock to be sold on its behalf to the public in an
underwritten offering; and

                  (b) all officers, directors and 5 percent stockholders of the
Company enter into or are bound by similar agreements.

         Such agreement shall be in writing in a form reasonably satisfactory to
the Company and such underwriter, provided that transfers to affiliates and
donees shall be permitted if the transferee agrees to be bound by the same
stand-off agreement originally executed by the transferor. The Company may
impose stop-transfer instructions with respect to the Registrable Shares or
other securities subject to the foregoing restriction until the end of the
stand-off period.

         9. Limitations on Subsequent Registration Rights. The Company shall
not, without the prior written consent of Preferred Holders holding at least
fifty-five percent (55%) of the Registrable Shares on an as-if-converted basis,
enter into any agreement (other than this Agreement) with any holder or
prospective holder of any securities of the Company which would allow such
holder or prospective holder (a) to include securities of the Company in any
Registration Statement, unless under the terms of such agreement, such holder or
prospective holder may include such securities in any such registration only on
terms substantially similar to the terms on which holders of Registrable Shares
may include shares in such registration, or (b) to make a demand registration
which could result in such registration statement being declared effective prior
to September 13, 2001. Notwithstanding the preceding sentence, any registration
rights with respect to Company securities given to any person or entity after
the date hereof other than pursuant to this Agreement shall be subordinate to
the rights of the Stockholders set forth herein unless Stockholders holding at
least 55% of the Registrable Shares consent in writing to such

                                       13
<PAGE>   14
rights, provided that such action taken pursuant to this Section 9 may be
effected only in a manner which affects all holders of Registrable Shares in the
same fashion.

         10. Rule 144 Requirements. After the earliest of (a) the closing of the
sale of securities of the Company pursuant to a Registration Statement, (b) the
registration by the Company of a class of securities under Section 12 of the
Exchange Act, or (c) the issuance by the Company of an offering circular
pursuant to Regulation A under the Securities Act, the Company agrees to:

                  (i) Comply with the requirements of Rule 144(c) under the
Securities Act with respect to current public information about the Company;

                  (ii) Use its best efforts to file with the Commission in a
timely manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act (at any time after it has become subject to
such reporting requirements); and

                  (iii) Furnish to any holder of Registrable Shares upon request
(A) a written statement by the Company as to its compliance with the
requirements of said Rule 144(c), and the reporting requirements of the
Securities Act and the Exchange Act (at any time after it has become subject to
such reporting requirements), (B) a copy of the most recent annual or quarterly
report of the Company, and (C) such other reports and documents of the Company
as such holder may reasonably request to avail itself of any similar rule or
regulation of the Commission allowing it to sell any such securities without
registration.

         11. Mergers, Etc. The Company shall not, directly or indirectly, enter
into any merger, consolidation or reorganization in which the Company shall not
be the surviving corporation unless the proposed surviving corporation shall,
prior to such merger, consolidation or reorganization, agree in writing to
assume the obligations of the Company under this Agreement, and for that purpose
references hereunder to "Registrable Shares" shall be deemed to be references to
the securities which the Stockholders would be entitled to receive in exchange
for Registrable Shares under any such merger, consolidation or reorganization;
provided, however, that the provisions of this Article III, Section 11 shall not
apply in the event of any merger, consolidation or reorganization in which the
Company is not the surviving corporation if all Stockholders are entitled to
receive in exchange for their Registrable Shares consideration consisting solely
of (a) cash, (b) securities of the acquiring corporation which may be
immediately sold to the public, without registration under the Securities Act
(including pursuant to Rule 144 (other than Rule 144(k)) and/or Rule 145
promulgated thereunder), or (c) securities of the acquiring corporation which
the acquiring corporation has agreed to register within 90 days of completion of
the transaction for resale to the public pursuant to the Securities Act.

ARTICLE IV.       RIGHT OF FIRST REFUSAL AGREEMENT ON COMPANY ISSUANCES

         1.       Right of First Refusal

                  (a) The Company shall not issue, sell or exchange, agree to
issue, sell or exchange, or reserve or set aside for issuance, sale or exchange,
(i) any shares of its Common Stock, (ii) any other equity securities of the
Company, including, without limitation, shares of preferred stock, (iii) any
option, warrant or other right to subscribe for, purchase or otherwise acquire
any equity securities of the Company, or (iv) any debt securities convertible
into capital stock of the Company (collectively, the "Offered Securities"),
unless in each such case the Company shall have first complied with this
Agreement. The Company shall deliver to each holder of at least 200,000 (two
hundred thousand) Shares (such number to be proportionately adjusted in the
event of any stock splits, stock dividends, recapitalizations or similar events
occurring on or after the date of this Agreement) (an "Offered Holder") a
written notice of any proposed or intended issuance, sale or exchange of Offered
Securities (the "Offer"), which Offer shall (i) identify and describe the
Offered Securities, (ii) describe the price and other terms upon which they are
to be issued, sold or exchanged, and the number or amount of the Offered
Securities to be issued, sold or exchanged, (iii) identify the persons or
entities, if known, to which or with which the Offered Securities are to be
offered, issued, sold or exchanged, and (iv) offer to issue and sell to or
exchange with such Offered Holder (A) such portion of the Offered Securities as
the aggregate number of Voting Shares then held by such Offered Holder bears to
the aggregate number of voting securities of the Company then outstanding (the
"Basic Amount"), and (B) such additional amount of the Offered Securities as
such Offered Holder indicates it will purchase or acquire should other Offered
Holders acquire less than their respective Basic Amounts (the "Undersubscription
Amount"). Each Offered Holder shall have the right, for a period of 30 days
following delivery of the offer, to purchase or acquire, at the price and upon
the other terms-specified in the Offer, the number or amount of Offered
Securities described above. The offer by its term shall remain open and
irrevocable for such 30-day period.

                  (b) For purposes of calculating an Offered Holder's ownership
of Shares, all shares of convertible Preferred Stock of the Company shall be
deemed to have been converted into shares of Common Stock.

                  (c) To accept an Offer, in whole or in part, an Offered Holder
must deliver a written notice to the Company prior to the end of the 30-day
period of the offer, setting forth the portion of the Offered Holder's Basic
Amount that such Offered Holder elects to purchase and, if such Offered Holder
shall elect to purchase all of its Basic Amount, the Undersubscription Amount
(if any) that such Offered Holder elects to purchase (the "Notice of
Acceptance"). If any Offered Holder subscribes for fewer Offered Securities than
its Basic Amount, then each Offered Holder who has set forth Undersubscription
Amounts in its Notice of Acceptance shall be entitled to purchase, in addition
to the Basic Amounts subscribed for, all Undersubscription Amounts it has

                                       15
<PAGE>   16
subscribed for; provided, however, that should the Undersubscription Amounts
subscribed for exceed the difference between the aggregate Basic Amounts for all
Offered Holders (the "Subject Offered Securities") and the Basic Amounts
subscribed for (the "Available Undersubscription Amount"), each Offered Holder
who has subscribed for any Undersubscription Amount shall be entitled to
purchase only that portion of the Available Undersubscription Amount as the
Undersubscription Amount subscribed for by such Offered Holder bears to the
total Undersubscription Amounts subscribed for by all Offered Holders, subject
to rounding by the Board of Directors to the extent it reasonably deems
necessary.

                  (d) In the event that Notices of Acceptance are not given by
the Offered Holders in respect of all the Subject Offered Securities, the
Company shall have 90 days from the expiration of the period set forth in
Article IV, Section l (a) to issue, sell or exchange all or any part of such
Subject Offered Securities (not including the Available Undersubscription
Amounts that Offered Holders are entitled to purchase pursuant to Article IV,
Section 1(c) above) as to which a Notice of Acceptance has not been given by the
Offered Holders (the "Refused Securities") as well as the balance of the Offered
Securities, but only to the offerees or purchasers described in the offer and
only upon terms and conditions (including, without limitation, unit prices and
interest rates) which are not more favorable, in the aggregate, to the acquiring
person or persons or less favorable to the Company than those set forth in the
Offer.

                  (e) Upon the closing of the issuance, sale or exchange of all
or less than all the Refused Securities and the balance of the Offered
Securities, the Offered Holders shall acquire from the Company, and the Company
shall issue to such Offered Holders, the number or amount of Offered Securities
specified in the Notices of Acceptance, upon the terms and conditions specified
in the Offer. The purchase by the Offered Holders of any Offered Securities is
subject in all cases to the preparation, execution and delivery by the Company
and such holders of a purchase agreement relating to such Offered Securities
reasonably satisfactory in form and substance to each such Offered Holders and
their respective counsel.

                  (f) Any Offered Securities not acquired by the Offered Holders
or other persons in accordance with Article IV, Section l(d) may not be issued,
sold or exchanged until they are again offered to the Offered Holders under the
procedures specified in this Article.

         2. Excluded Issuances. The rights of the Offered Holders under this
Article IV shall not apply to:

                  (a) Common Stock issued as a stock dividend to holders of
Common Stock or upon any subdivision or combination of shares of Common Stock;

                  (b) The issuance of any shares of Common Stock upon conversion
of outstanding shares of Preferred Stock;

                                       16
<PAGE>   17
                  (c) Up to 5,284,302 shares of Common Stock or such greater
number as is unanimously approved by the Board of Directors, or options
exercisable therefor, including options outstanding on the date of this
Agreement (such number to be proportionately adjusted in the event of any stock
splits, stock dividends, recapitalizations or similar events occurring on or
after the date of this Agreement) issuable to officers, directors, consultants
and employees of the Company or any subsidiary pursuant to any plan, agreement
or arrangement approved by a vote of not less than a majority of the Board of
Directors of the Company;

                  (d) Securities issued solely in consideration for the
acquisition (whether by merger or otherwise) by the Company or any of its
subsidiaries of all or substantially all of the stock or assets of any other
entity;

                  (e) Shares of Common Stock sold by the Company in an
underwritten public offering pursuant to an effective registration statement
under the Securities Act;

                  (f) The issuance of stock, warrants or other securities or
rights to persons or entities with which the Company has business relationships
provided (A) such issuances are for other than primarily equity financing
purposes as determined by the Company's Board of Directors, (B) such issuances
are not to pre-existing holders of Preferred Stock of the Company or their
affiliates and (C) such issuances are approved by all members of the Company's
Board of Directors; or

                  (g) (i) The issuance and sale of shares of Series D Preferred
pursuant to the Series D Stock Purchase Agreement and (ii) the issuance of any
shares of Common Stock upon conversion of shares of Series D Preferred.

ARTICLE V. RIGHT OF FIRST REFUSAL AND CO-SALE AGREEMENT ON TRANSFERS BY FOUNDERS

         1.       Restrictions on Transfer.

                  (a) Any sale or other disposition of any Voting Shares by a
Founder, other than according to the terms of this Agreement, shall be void and
transfer no right, title or interest in or to any of such Voting Shares to the
purported transferee.

                  (b) Each Founder agrees to present the certificates
representing the Voting Shares presently owned or hereafter acquired by him to
the Secretary of the Company and cause the Secretary to stamp on the certificate
in a prominent manner the following legend:

                           "The sale or other disposition of any of the shares
                           represented by this certificate is restricted by an
                           Investor Rights Agreement (as the same may be amended
                           or amended and restated from time to

                                       17
<PAGE>   18
                           time) by and among certain of the shareholders of
                           this corporation and this corporation (the
                           "Agreement"). A copy of the Agreement is available
                           for inspection during normal business hours at the
                           office of the Secretary of the corporation."

         2.       Transfers Not Subject to Restrictions.

                  (a) Subject to Section 2 of Article X hereof, any Founder may
sell, assign or transfer Voting Shares to (i) his spouse, children, issue,
siblings, siblings-in-law or parents, parents-in-law, or to a trust established
for the benefit of his spouse, children, issue, siblings, siblings-in-law,
parents, parents-in-law or himself, or dispose of them under his will, or (ii)
any other Founder, without compliance with Sections 3 and 6 of this Article V.

                  (b) The rights of the Company and the Offered Holders under
Sections 4 and 5 of this Article V shall not apply to any pledge of Voting
Shares by a Founder which creates a mere security interest, provided the pledgee
provides the Company with a written agreement to be bound hereby to the same
extent as the pledging Founder.

         3.       Offer of Sale; Notice of Proposed Sale.

         If any Founder desires to sell, transfer or otherwise dispose of any of
his Voting Shares, or of any interest in such Voting Shares, whether voluntarily
or by operation of law, in any transaction other than pursuant to Section 2 of
this Article V, such Founder (the "Selling Founder") shall first deliver written
notice of his desire to do so (the "Notice") to the Company and the Offered
Holders, in the manner prescribed in Section 6 of Article V hereof. The Notice
must specify: (i) the name and address of the party, to which the Selling
Founder proposes to sell or otherwise dispose of the Voting Shares or an
interest in the Voting Shares (the "Offeror"), (ii) the number of Voting Shares
the Selling Founder proposes to sell or otherwise dispose of (the "Offered
Shares"), (iii) the consideration per Voting Share to be delivered to the
Selling Founder for the proposed sale, transfer or disposition, and (iv) all
other material terms and conditions of the proposed transaction.

         4. Company's Option to Purchase.

                  (a) Subject to Section 6(a) of this Article V, the Company
shall have the first option to purchase all or any part of the Offered Shares
for the consideration per share and on the terms and conditions specified in the
Notice. The Company must exercise such option, no later than 15 days after such
Notice is deemed under Section 6 of this Article V to have been delivered to it,
by written notice to the Selling Founder.

                  (b) In the event the Company does not exercise its option
within such 15-day period with respect to all of the Offered Shares, the
Secretary of the Company

                                       18
<PAGE>   19
shall, by the last day of such period, give written notice of that fact to the
Offered Holders (the "Offered Holders Notice"). The Offered Holders Notice shall
specify the number of Offered Shares not purchased by the Company (the
"Remaining Shares").

                  (c) In the event the Company duly exercises its option to
purchase all or part of the Offered Shares, the closing of such purchase shall
take place at the offices of the Company on the later of (i) the date five days
after the expiration of such 15-day period or (ii) the date that the Offered
Holders consummate their purchase of Offered Shares under Section 5(c) of this
Article V.

                  (d) To the extent that the consideration proposed to be paid
by the offeror for the Offered Shares consists of property other than cash or a
promissory note, the consideration required to be paid by the Company and/or the
Offered Holders exercising their options under Sections 4 and 5 of this Article
V may consist of cash equal to the value of such property, as determined in good
faith by agreement of the Selling Founder and the Company and/or the Offered
Holders acquiring such Offered Shares.

                  (e) Notwithstanding anything to the contrary herein, neither
the Company nor any Offered Holders shall have any right to purchase any of the
Offered Shares hereunder unless the Company and/or such Offered Holders exercise
their option to purchase all of the Offered Shares.

         5.       Offered Holders' Option to Purchase.

                  (a) Subject to Section 6(a) of this Article V, each Offered
Holder shall have an option, exercisable for a period of 15 days from the date
of delivery of the Offered Holders Notice, to purchase on a pro rata basis
(subject to adjustment pursuant to Section 5(b)), according to the number of
Voting Shares owned by such Offered Holder in proportion to the number of Voting
Shares held by all Offered Holders, of the Remaining Shares for the
consideration per share and on the terms and conditions set forth in the Notice.
Such option shall be exercised by delivery of written notice to the Secretary of
the Company. Alternatively, each Offered Holder may within the same 15-day
period, notify the Secretary of the Company of his or its desire to participate
in the sale of Voting Shares held by him or it on the terms set forth in the
Notice, and the number of Voting Shares he or it wishes to sell.

                  (b) In the event options to purchase have been exercised by
the Offered Holders with respect to some but not all of the Remaining Shares,
those Offered Holders who have exercised their options within the 15-day period
specified in Section 5(a) shall have an additional option, for a period of five
days next succeeding the expiration of such 15-day period, to purchase all or
any part of the balance of such Remaining Shares on the terms and conditions set
forth in the Notice, which option shall be exercised by the delivery of written
notice to the Secretary of the Company. In the event there are two or more such
Offered Holders that choose to exercise the last mentioned option for a total
number of Voting Shares in excess of the number available,

                                       19
<PAGE>   20
the Remaining Shares available for each such Offered Holder's option shall be
allocated to such Offered Holder pro rata based on the number of Voting Shares
owned by the Offered Holders so electing.

                  (c) If the option to purchase the Remaining Shares is
exercised in full by the Offered Holders, the closing of the purchase of the
Remaining Shares shall take place at the offices of the Company no later five
days after the exercise of such purchase option by the Offered Holder or Offered
Holders.

         6.       Failure to Fully Exercise Options; Co-Sale.

                  (a) If the Company and the Offered Holders do not exercise
their options to purchase all of the Offered Shares within the periods described
in this Agreement (the "Option Period"), then all options of the Company and the
Offered Holders to purchase the Offered Shares, whether exercised or not, shall
terminate, but each Offered Holder which has, pursuant to Section 5 of this
Article V, expressed a desire to sell Voting Shares in the transaction (a
"Participating Offered Holder"), shall be entitled to do so pursuant to this
Section. The Secretary of the Company, shall promptly, on expiration of the
Option Period, notify the Selling Founder of the aggregate number of Voting
Shares the Participating Offered Holders wish to sell. The Selling Founder shall
use his best efforts to interest the Offeror in purchasing, in addition to the
offered Shares, the Voting Shares the Participating Offered Holders wish to
sell. If the offeror does not wish to purchase all of the Voting Shares made
available by the Selling Founder and the Participating Offered Holders, then
each Participating Offered Holder and the Selling Founder shall be entitled to
sell, at the price and on the terms and conditions set forth in the Notice, a
portion of the Voting Shares being sold to the offeror, in the same proportion
as such Selling Founder or Participating Offered Holder's ownership of Voting
Shares bears to the aggregate number of Voting Shares owned by the Selling
Founder and the Participating Offered Holders. The transaction contemplated by
the Notice shall be consummated not later than 60 days after the expiration of
the Option Period.

                  (b) If the Participating Offered Holders do not elect to sell
the full number of Voting Shares which they are entitled to sell pursuant to
Section 6(a), the Selling Founder shall be entitled to sell to the offeror,
according to the terms set forth in the Notice, that number of his own Voting
Shares which equals the difference between the number of Voting Shares desired
to be purchased by the offeror and the number of Voting Shares the Participating
Offered Holders wish to sell. If the Selling Founder wishes to sell, transfer or
otherwise dispose of any such Voting Shares at a price per Voting Share which
differs from that set forth in the Notice, upon terms different from those
previously offered to the Company and the Offered Holders, or more than 60 days
after the expiration of the Option Period, as a condition precedent to such
transaction, such Voting Shares must first be offered to the Company and the
Offered Holders on the same terms and procedures and time periods set forth
above.

<PAGE>   21
                  (c) The proceeds of any sale made by the Selling Founder
without compliance with the provisions of this Section 6 shall be deemed to be
held in constructive trust in such amount as would have been due the
Participating Offered Holders if the Selling Founder had complied with this
Agreement.

         7. Other Rights Not Affected. Notwithstanding anything to the contrary
contained in this Article V, nothing in this Article V shall limit any right of
the Company to repurchase any shares from a Founder which have not yet vested
pursuant to the terms of any other agreement between the Company and such
Founder.

                  may not be offered, sold or otherwise transferred, pledged or

ARTICLE IX.  STANDSTILL AGREEMENT.

                  1.       Standstill Agreement

                  (a) Subject to the provisions of Section 1(b) of this Article
IX, the Series D Holders agree that, for the period beginning on April 20, 2000
and terminating on the earliest to occur of (i) such time as a person or entity
not currently a party to this Agreement acquires at least a majority of the
voting power of all outstanding capital stock of the Company, (ii) April 20,
2010 or (iii) with respect to a particular Series D Holder, such time as such
Series D Holder no longer holds any of the Series D Preferred originally issued
and sold to such holder on April 20, 2000 (the "Standstill Period"), unless it
has obtained the prior written consent of the Company, it will not, alone or as
a member of any Group:

                  (i) acquire, directly or indirectly, by purchase or otherwise,
of record or beneficially, any capital stock of the Company, or rights or
options to acquire capital stock of the Company, if after such acquisition (and
giving effect to the exercise of any such rights or options) a Series D Holder
(either alone or as a member of a Group) would own of record or beneficially in
the aggregate more than 6.1% of the issued and outstanding Capital Stock of the
Company (the "Percent Limit"); provided that notwithstanding the provisions of
this clause (i), if the number of shares of outstanding Capital Stock of the
Company is reduced or if the aggregate ownership of the Series D Holders is
increased as a result of a recapitalization of the Company, or as a result of
any other action taken by the Company, the Series D Holder will not be required
to dispose of (and may continue to vote) any of its holdings of Capital Stock
even though such action resulted in the Series D Holders' ownership exceeding
the percentage of Capital Stock which the Series D Holders would then be
permitted to own. Except as otherwise provided above, if the Series D Holders
shall at any time during the Standstill Period own in the aggregate in excess of
the maximum percentage of the Capital Stock at the time permitted by this clause
(i), (a) the Series D Holders shall sell as promptly as practicable under the
circumstances sufficient Capital Stock so that after such sale the Series D
Holders shall not own in the aggregate more than the applicable maximum
permitted percentage of Capital Stock, and (b) the Series D Holders shall
refrain from voting on any matter as to which the holders of Capital Stock shall
have the right to vote with respect to any capital stock held by the Series D
Holders in excess of the Percent Limit;

                  (ii) "solicit" proxies with respect to Capital Stock under any
circumstances or become a "participant" in any "election contest" relating to
the election of directors of the Company, as such terms are defined in
Regulation 14A under the Exchange Act; deposit any Capital Stock in a voting
trust or subject them to a voting agreement or other agreement of similar effect
(other than pursuant to this Agreement or any amendment, modification or
supplement to this Agreement);

                                       26
<PAGE>   27
                  (iii) initiate, propose or otherwise solicit stockholders for
the approval of one or more stockholder proposals at any time or induce or
attempt to induce any other person to initiate any stockholder proposal;

                  (iv) Intentionally Omitted; or

                  (v) initiate, propose or otherwise solicit any proposals for
the acquisition of the Company or a controlling interest therein.

         The provisions of this Section 1(a) shall not apply to any of the
activities restricted by subsections (i) through (v) to the extent that, and for
as long as, either (a) the Board of Directors of the Company has publicly
announced it is seeking bids from third parties for the acquisition of the
Company or (b) a third party not affiliated with the Series D Holders announces
an offer to acquire a majority of the capital shares of the Company.

                  (b) For purposes of Section 1(a), the Series D Holders shall
not be deemed to own indirectly or beneficially any Capital Stock of the
Company, or rights or options to acquire Capital Stock of the Company, that are
owned by any entity of which any of the Series D Holders is a limited partner
only or in which any of the Series D Holders otherwise owns a minority equity
interest.

ARTICLE X.        GENERAL

         1. Termination. Notwithstanding any other provision hereof, Article II
of this Agreement shall terminate in its entirety on the earlier of (a) the

and complete agreement of the parties hereto with respect to the subject matter
hereof and supersedes the Existing Agreement which is hereby terminated

in accordance with this Section 8 shall be binding upon each holder of any
Preferred Stock (including shares of Common Stock into which any shares of
Preferred Stock have been converted), each future holder of all such securities
and the Company. No waivers of or exceptions to any term, condition or provision
of this Agreement, in any one or more instances, shall be deemed to be, or

provision.
