                               NETEZZA CORPORATION

                       Nonstatutory Stock Option Agreement
                     Granted Under 2000 Stock Incentive Plan

1. Grant of Option.

     This agreement evidences the grant by Netezza Corporation, a Delaware
corporation (the "Company"), on ___________, 200_ to _____________, an
[employee], [consultant], [director] of the Company (the "Participant"), of an
option to purchase, in whole or in part, on the terms provided herein and in the
Company's 2000 Stock Incentive Plan (the "Plan"), a total of ___________ shares
(the "Shares") of common stock, $.001 par value per share, of the Company
("Common Stock") at $__________ per Share. Unless earlier terminated, this
option shall expire on _________, 201_ (the "Final Exercise Date").

     It is intended that the option evidenced by this agreement shall not be an
incentive stock option as defined in Section 422 of the Internal Revenue Code of
1986, as amended and any regulations promulgated thereunder (the "Code"). Except
as otherwise indicated by the context, the term "Participant," as used in this
option, shall be deemed to include any person who acquires the right to exercise
this option validly under its terms.

2. Vesting Schedule.

     This option will become exercisable ("vest") as to 25% of the original
number of Shares on the first anniversary of ___________, 200_ (the "Vesting
Start Date") and as to an additional 6.25% of the original number of Shares at
the end of each successive three-month period following the first anniversary of
the Vesting Start Date until the fourth anniversary of the Vesting Start Date.

     The right of exercise shall be cumulative so that to the extent the option
is not exercised in any period to the maximum extent permissible it shall
continue to be exercisable, in whole or in part, with respect to all shares for
which it is vested until the earlier of the Final Exercise Date or the
termination of this option under Section 4 hereof or the Plan.

3. Acceleration of Vesting Schedule. Notwithstanding the vesting schedule
described above in Section 2, effective immediately prior to an Acquisition (as
defined below), this option shall become exercisable for such number of
additional Shares as is equal to 25% of the total number of Shares originally
covered by this option, except that for employees who have been employed by the
Company for less than one year as of the date of such Acquisition, this option
only shall become exercisable for such number of Shares as is equal to 12.5% of
the total number of Shares originally covered by this option, with the remaining
shares in each case continuing to vest in accordance with a vesting schedule
that has been shortened by one year or six months, respectively. For purposes of
this option, the term "Acquisition" shall mean (1) any merger or consolidation
in which (i) the Company is a constituent party or (ii) a subsidiary of the
Company is a constituent party and the Company issues shares of its capital
stock pursuant to such merger or consolidation (except, in the case of both
clauses (i) and (ii) above, any such merger or

<PAGE>

consolidation involving the Company or a subsidiary in which the holders of
capital stock of the Company immediately prior to such merger or consolidation
continue to hold immediately following such merger or consolidation at least 51%
by voting power of the capital stock of (x) the surviving or resulting
corporation or (y) if the surviving or resulting corporation is a wholly owned
subsidiary of another corporation immediately following such merger or
consolidation, of the parent corporation of such surviving or resulting
corporation) or (2) the sale or transfer, in a single transaction or series of
related transactions, of outstanding capital stock representing at least 51% of
the voting power of the outstanding capital stock of the Company immediately
following such transaction or (3) the sale of all or substantially all of the
assets of the Company.

4. Exercise of Option.

     (a) Form of Exercise. Each election to exercise this option shall be in
substantially the form attached hereto as Exhibit A, signed by the Participant,
and received by the Company at its principal office, accompanied by this
agreement, and payment in full in the manner provided in the Plan. The
Participant may purchase less than the number of shares covered hereby, provided
that no partial exercise of this option may be for any fractional share or for
fewer than ten whole shares.

     (b) Continuous Relationship with the Company Required. Except as otherwise
provided in this Section 4, this option may not be exercised unless the
Participant, at the time he or she exercises this option, is, and has been at
all times since the date hereof, an employee, officer or director of, or
consultant or advisor to, the Company or any parent or subsidiary of the Company
as defined in Section 424(e) or (f) of the Code (an "Eligible Participant").

     (c) Termination of Relationship with the Company. If the Participant ceases
to be an Eligible Participant for any reason, then, except as provided in
paragraphs (d) and (e) below, the right to exercise this option shall terminate
three months after such cessation (but in no event after the Final Exercise
Date), provided that this option shall be exercisable only to the extent that
the Participant was entitled to exercise this option on the date of such
cessation. Notwithstanding the foregoing, if the Participant, prior to the Final
Exercise Date, violates the non-competition or confidentiality provisions of any
employment contract, confidentiality and nondisclosure agreement or other
agreement between the Participant and the Company, the right to exercise this
option shall terminate immediately upon written notice to the Participant from
the Company describing such violation.

     (d) Exercise Period Upon Death or Disability. If the Participant dies or
becomes disabled (within the meaning of Section 22(e)(3) of the Code) prior to
the Final Exercise Date while he or she is an Eligible Participant and the
Company has not terminated such relationship for "cause" as specified in
paragraph (e) below, this option shall be exercisable, within the period of one
year following the date of death or disability of the Participant by the
Participant, provided that this option shall be exercisable only to the extent
that this option was exercisable by the Participant on the date of his or her
death or disability, and further provided that this option shall not be
exercisable after the Final Exercise Date.

     (e) Discharge for Cause. If the Participant, prior to the Final Exercise
Date, is discharged by the Company for "cause" (as defined below), the right to
exercise this option shall

                                       -2-

<PAGE>

terminate immediately upon the effective date of such discharge. "Cause" shall
mean willful misconduct by the Participant or willful failure by the Participant
to perform his or her responsibilities to the Company (including, without
limitation, breach by the Participant of any provision of any employment,
consulting, advisory, nondisclosure, non-competition or other similar agreement
between the Participant and the Company), as determined by the Company, which
determination shall be conclusive. The Participant shall be considered to have
been discharged for "Cause" if the Company determines, within 30 days after the
Participant's resignation, that discharge for cause was warranted.

5. Right of First Refusal.

     (a) If the Participant proposes to sell, assign, transfer, pledge,
hypothecate or otherwise dispose of, by operation of law or otherwise
(collectively, "transfer") any Shares acquired upon exercise of this option,
then the Participant shall first give written notice of the proposed transfer
(the "Transfer Notice") to the Company. The Transfer Notice shall name the
proposed transferee and state the number of such Shares the Participant proposes
to transfer (the "Offered Shares"), the price per share and all other material
terms and conditions of the transfer.

     (b) For 30 days following its receipt of such Transfer Notice, the Company
shall have the option to purchase all (but not less than all) of the Offered
Shares at the price and upon the terms set forth in the Transfer Notice. In the
event the Company elects to purchase all of the Offered Shares, it shall give
written notice of such election to the Participant within such 30-day period.
Within 10 days after his receipt of such notice, the Participant shall tender to
the Company at its principal offices the certificate or certificates
representing the Offered Shares, duly endorsed in blank by the Participant or
with duly endorsed stock powers attached thereto, all in a form suitable for
transfer of the Offered Shares to the Company. Promptly following receipt of
such certificate or certificates, the Company shall deliver or mail to the
Participant a check in payment of the purchase price for the Offered Shares;
provided that if the terms of payment set forth in the Transfer Notice were
other than cash against delivery, the Company may pay for the Offered Shares on
the same terms and conditions as were set forth in the Transfer Notice; and
provided further that any delay in making such payment shall not invalidate the
Company's exercise of its option to purchase the Offered Shares.

     (c) If the Company does not elect to acquire all of the Offered Shares, the
Participant may, within the 30-day period following the expiration of the option
granted to the Company under subsection (b) above, transfer the Offered Shares
to the proposed transferee, provided that such transfer shall not be on terms
and conditions more favorable to the transferee than those contained in the
Transfer Notice. Notwithstanding any of the above, all Offered Shares
transferred pursuant to this Section 5 shall remain subject to the right of
first refusal set forth in this Section 5 and such transferee shall, as a
condition to such transfer, deliver to the Company a written instrument
confirming that such transferee shall be bound by all of the terms and
conditions of this Section 5.

     (d) After the time at which the Offered Shares are required to be delivered
to the Company for transfer to the Company pursuant to subsection (b) above, the
Company shall not pay any dividend to the Participant on account of such Offered
Shares or permit the Participant

                                       -3-

<PAGE>

to exercise any of the privileges or rights of a stockholder with respect to
such Offered Shares, but shall, in so far as permitted by law, treat the Company
as the owner of such Offered Shares.

     (e) The following transactions shall be exempt from the provisions of this
Section 5:

          (1) any transfer of Shares to or for the benefit of any spouse, child
or grandchild of the Participant, or to a trust for their benefit;

          (2) any transfer pursuant to an effective registration statement filed
by the Company under the Securities Act of 1933, as amended (the "Securities
Act"); and

          (3) an Acquisition;

provided, however, that in the case of a transfer pursuant to clause (1) above,
such Shares shall remain subject to the right of first refusal set forth in this
Section 5 and such transferee shall, as a condition to such transfer, deliver to
the Company a written instrument confirming that such transferee shall be bound
by all of the terms and conditions of this Section 5.

     (f) The Company may assign its rights to purchase Offered Shares in any
particular transaction under this Section 5 to one or more persons or entities.

     (g) The provisions of this Section 5 shall terminate upon the earlier of
the following events:

          (1) the closing of the sale of shares of Common Stock in an
underwritten public offering pursuant to an effective registration statement
filed by the Company under the Securities Act; or

          (2) an Acquisition.

     (h) The Company shall not be required (a) to transfer on its books any of
the Shares which shall have been sold or transferred in violation of any of the
provisions set forth in this Section 5, or (b) to treat as owner of such Shares
or to pay dividends to any transferee to whom any such Shares shall have been so
sold or transferred.

6. Agreement in Connection with Public Offering.

     The Participant agrees, in connection with the initial underwritten public
offering of the Company's securities pursuant to a registration statement under
the Securities Act, (i) not to sell, make short sale of, loan, grant any options
for the purchase of, or otherwise dispose of any shares of Common Stock held by
the Participant (other than those shares included in the offering) without the
prior written consent of the Company or the underwriters managing such initial
underwritten public offering of the Company's securities for a period of 180
days from the effective date of such registration statement, and (ii) to execute
any agreement reflecting clause (i) above as may be requested by the Company or
the managing underwriters at the time of such offering.

                                       -4-

7. Withholding.

     No Shares will be issued pursuant to the exercise of this option unless and
until the Participant pays to the Company, or makes provision satisfactory to
the Company for payment of, any federal, state or local withholding taxes
required by law to be withheld in respect of this option.

8. Nontransferability of Option.

     This option may not be sold, assigned, transferred, pledged or otherwise
encumbered by the Participant, either voluntarily or by operation of law, except
by will or the laws of descent and distribution, and, during the lifetime of the
Participant, this option shall be exercisable only by the Participant.

9. Provisions of the Plan.

     This option is subject to the provisions of the Plan, a copy of which is
furnished to the Participant with this option.

     IN WITNESS WHEREOF, the Company has caused this option to be executed under
its corporate seal by its duly authorized officer. This option shall take effect
as a sealed instrument.

                               NETEZZA CORPORATION

                           Restricted Stock Agreement
                     Granted Under 2000 Stock Incentive Plan

     AGREEMENT made this _____ day of _____________, 200_, between Netezza
Corporation, a Delaware corporation (the "Company"), and _______________ (the
"Participant").

     For valuable consideration, receipt of which is acknowledged, the parties
hereto agree as follows:

     1. Purchase of Shares.

     The Company shall issue and sell to the Participant, and the Participant
shall purchase from the Company, subject to the terms and conditions set forth
in this Agreement and in the Company's 2000 Stock Incentive Plan (the "Plan"),
________ shares (the "Shares") of common stock, $.001 par value, of the Company
("Common Stock"), at a purchase price of $___ per share. The aggregate purchase
price for the Shares shall be paid by the Participant by check payable to the
order of the Company or such other method as may be acceptable to the Company.
Upon receipt by the Company of payment for the Shares, the Company shall issue
to the Participant one or more certificates in the name of the Participant for
that number of Shares purchased by the Participant. The Participant agrees that
the Shares shall be subject to the purchase options set forth in Sections 2 and
5 of this Agreement and the restrictions on transfer set forth in Section 4 of
this Agreement.

     2. Purchase Option.

     (a) In the event that the Participant ceases to be employed by the Company
for any reason or no reason, with or without cause, prior to the fourth
anniversary of __________ (the "Date of Grant"), the Company shall have the
right and option (the "Purchase Option") to purchase from the Participant, for a
sum of $____ per share (the "Option Price"), some or all of the Unvested Shares
(as defined below). "Unvested Shares" means the Shares which have not vested in
accordance with the following vesting schedule at the time the Purchase Option
becomes exercisable by the Company: 25% of the Shares shall vest on the first
anniversary of the Date of Grant; and 6.25% of the Shares shall vest at the end
of each three-month period following the first anniversary of the Date of Grant,
with the final 6.25% vesting on the fourth anniversary of the Date of Grant.

     (b) Notwithstanding the foregoing, upon the occurrence of an Acquisition
(as defined below) of the Company, an additional 25% of the Shares shall vest if
the Participant has been employed by the Company for at least one year at such
time, and an additional 12.5% of the Shares shall vest if the Participant has
been employed by the Company for less than one year at such time, with the
remaining Shares in each case continuing to vest in accordance with a vesting
schedule that has been shortened by one year or six months, respectively. For
purposes of this

<PAGE>

Agreement, "Acquisition" shall mean (A) any merger or consolidation in which (i)
the Company is a constituent party or (ii) a subsidiary of the Company is a
constituent party and the Company issues shares of its capital stock pursuant to
such merger or consolidation (except, in the case of both clauses (i) and (ii)
above, any such merger or consolidation involving the Company or a subsidiary in
which the holders of capital stock of the Company immediately prior to such
merger or consolidation continue to hold immediately following such merger or
consolidation at least 51% by voting power of the capital stock of (x) the
surviving or resulting corporation or (y) if the surviving or resulting
corporation is a wholly owned subsidiary of another corporation immediately
following such merger or consolidation, of the parent corporation of such
surviving or resulting corporation) or (B) the sale or transfer, in a single
transaction or series of related transactions, of outstanding capital stock
representing at least 51% of the voting power of the outstanding capital stock
of the Company immediately following such transaction or (C) the sale of all or
substantially all of the assets of the Company.

     (c) For purposes of this Agreement, employment with the Company shall
include employment with a parent or subsidiary of the Company.

     3. Exercise of Purchase Option and Closing.

     (a) The Company may exercise the Purchase Option by delivering or mailing
to the Participant (or his estate), within 60 days after the termination of the
employment of the Participant with the Company, a written notice of exercise of
the Purchase Option. Such notice shall specify the number of Shares to be
purchased. If and to the extent the Purchase Option is not so exercised by the
giving of such a notice within such 60-day period, the Purchase Option shall
automatically expire and terminate effective upon the expiration of such 60-day
period.

     (b) Within 10 days after delivery to the Participant of the Company's
notice of the exercise of the Purchase Option pursuant to subsection (a) above,
the Participant (or his estate) shall, pursuant to the provisions of the Joint
Escrow Instructions referred to in Section 7, tender to the Company at its
principal offices the certificate or certificates representing the Shares which
the Company has elected to purchase in accordance with the terms of this
Agreement, duly endorsed in blank or with duly endorsed stock powers attached
thereto, all in form suitable for the transfer of such Shares to the Company.
Promptly following its receipt of such certificate or certificates, the Company
shall pay to the Participant the aggregate Option Price for such Shares
(provided that any delay in making such payment shall not invalidate the
Company's exercise of the Purchase Option with respect to such Shares).

     (c) After the time at which any Shares are required to be delivered to the
Company for transfer to the Company pursuant to subsection (b) above, the
Company shall not pay any dividend to the Participant on account of such Shares
or permit the Participant to exercise any of the privileges or rights of a
stockholder with respect to such Shares, but shall, in so far as permitted by
law, treat the Company as the owner of such Shares.

     (d) The Option Price may be payable, at the option of the Company, in
cancellation of all or a portion of any outstanding indebtedness of the
Participant to the Company or in cash (by check) or both.

                                      -2-

<PAGE>

     (e) The Company shall not purchase any fraction of a Share upon exercise of
the Purchase Option, and any fraction of a Share resulting from a computation
made pursuant to Section 2 of this Agreement shall be rounded to the nearest
whole Share (with any one-half Share being rounded upward).

     (f) The Company may assign its Purchase Option to one or more persons or
entities.

     4. Restrictions on Transfer.

     The Participant shall not sell, assign, transfer, pledge, hypothecate or
otherwise dispose of, by operation of law or otherwise (collectively
"transfer"):

     (a) any Shares, or any interest therein, that are subject to the Purchase
Option, except that the Participant may transfer such Shares (i) to or for the
benefit of any spouse, child or grandchild of the Participant, or to a trust,
partnership or other entity for their benefit, provided that such Shares shall
remain subject to this Agreement (including without limitation the restrictions
on transfer set forth in this Section 4, the Purchase Option and the right of
first refusal set forth in Section 5) and such permitted transferee shall, as a
condition to such transfer, deliver to the Company a written instrument
confirming that such transferee shall be bound by all of the terms and
conditions of this Agreement or (ii) as part of the sale of all or substantially
all of the shares of capital stock of the Company (including pursuant to a
merger or consolidation), provided that, in accordance with the Plan, the
securities or other property received by the Participant in connection with such
transaction shall remain subject to this Agreement; or

     (b) any Shares, or any interest therein, that are no longer subject to the
Purchase Option, except in accordance with Section 5 below.

     5. Right of First Refusal.

     (a) If the Participant proposes to transfer any Shares that are no longer
subject to the Purchase Option (either because they are no longer Unvested
Shares or because the Purchase Option expired unexercised), then the Participant
shall first give written notice of the proposed transfer (the "Transfer Notice")
to the Company. The Transfer Notice shall name the proposed transferee and state
the number of such Shares he proposes to transfer (the "Offered Shares"), the
price per share and all other material terms and conditions of the transfer.

     (b) For 30 days following delivery to the Company of such Transfer Notice,
the Company shall have the option to purchase all (but not less than all) of the
Offered Shares at the price and upon the terms set forth in the Transfer Notice.
In the event the Company elects to purchase all of the Offered Shares, it shall
give written notice of such election to the Participant within such 30-day
period. Within 10 days after delivery to the Participant of such notice, the
Participant shall tender to the Company at its principal offices the certificate
or certificates representing the Offered Shares, duly endorsed in blank by the
Participant or with duly endorsed stock powers attached thereto, all in form
suitable for transfer of the Offered Shares to the Company. Promptly following
receipt of such certificate or certificates, the Company shall deliver or mail
to the Participant a check in payment of the purchase price for the Offered
Shares; provided that if the terms of payment set forth in the Transfer Notice
were other than

                                      -3-

<PAGE>

cash against delivery, the Company may pay for the Offered Shares on the same
terms and conditions as were set forth in the Transfer Notice; and provided
further that any delay in making such payment shall not invalidate the Company's
exercise of its option to purchase the Offered Shares.

     (c) If the Company does not elect to acquire all of the Offered Shares, the
Participant may, within the 30-day period following the expiration of the option
granted to the Company under subsection (b) above, transfer the Offered Shares
to the proposed transferee, provided that such transfer shall not be on terms
and conditions more favorable to the transferee than those contained in the
Transfer Notice. Notwithstanding any of the above, all Offered Shares
transferred pursuant to this Section 5 shall remain subject to this Agreement
(including without limitation the restrictions on transfer set forth in Section
4 and the right of first refusal set forth in this Section 5) and such
transferee shall, as a condition to such transfer, deliver to the Company a
written instrument confirming that such transferee shall be bound by all of the
terms and conditions of this Agreement.

     (d) After the time at which the Offered Shares are required to be delivered
to the Company for transfer to the Company pursuant to subsection (b) above, the
Company shall not pay any dividend to the Participant on account of such Offered
Shares or permit the Participant to exercise any of the privileges or rights of
a stockholder with respect to such Shares, but shall, in so far as permitted by
law, treat the Company as the owner of such Offered Shares.

provided, however, that in the case of a transfer pursuant to clause (1) above,

Agreement.

          transferred or otherwise disposed of in the absence of an effective
          registration statement under such Act or an opinion of counsel
          satisfactory to the corporation to the effect that such registration
          is not required."

                                      -5-

     9. Provisions of the Plan.

     (a) This Agreement is subject to the provisions of the Plan, a copy of
which is furnished to the Participant with this Agreement.

     (b) As provided in the Plan, upon the occurrence of a Reorganization Event
(as defined in the Plan), the repurchase and other rights of the Company
hereunder shall inure to the benefit of the Company's successor and shall apply
to the cash, securities or other property which the Common Stock was converted
into or exchanged for pursuant to such Reorganization Event in the same manner
and to the same extent as they applied to the Common Stock hereunder. If, in
connection with a Reorganization Event, a portion of the cash, securities and/or
other property received upon the conversion or exchange of the Common Stock
subject hereto is to be placed into escrow to secure indemnification or similar
obligations, the mix between the vested and unvested portion of such cash,
securities and/or other property that is placed into escrow shall be the same as
the mix between the vested and unvested portion of such cash, securities and/or
other property that is not subject to escrow.

     10. Investment Representations.

     The Participant represents, warrants and covenants as follows:

     (a) The Participant is purchasing the Shares for his own account for
investment only, and not with a view to, or for sale in connection with, any
distribution of the Shares in violation of the Securities Act, or any rule or
regulation under the Securities Act.

     (b) The Participant has had such opportunity as he has deemed adequate to
obtain from representatives of the Company such information as is necessary to
permit him to evaluate the merits and risks of his investment in the Company.

     (c) The Participant has sufficient experience in business, financial and
investment matters to be able to evaluate the risks involved in the purchase of
the Shares and to make an informed investment decision with respect to such
purchase.

     (d) The Participant can afford a complete loss of the value of the Shares
and is able to bear the economic risk of holding such Shares for an indefinite
period.

     (e) The Participant understands that (i) the Shares have not been
registered under the Securities Act and are "restricted securities" within the
meaning of Rule 144 under the Securities Act; (ii) the Shares cannot be sold,
transferred or otherwise disposed of unless they are subsequently registered
under the Securities Act or an exemption from registration is then available;
(iii) in any event, the exemption from registration under Rule 144 will not be
available for at least one year and even then will not be available unless a
public market then exists for the Common Stock, adequate information concerning
the Company is then available to the public, and other terms and conditions of
Rule 144 are complied with; and (iv) there is now no registration statement on
file with the Securities and Exchange Commission with respect to any stock of
the Company and the Company has no obligation or current intention to register
the Shares under the Securities Act.

     11. Withholding Taxes; Section 83(b) Election.

     (a) The Participant acknowledges and agrees that the Company has the right
to deduct from payments of any kind otherwise due to the Participant any
federal, state or local taxes of any kind required by law to be withheld with
respect to the purchase of the Shares by the Participant or the lapse of the
Purchase Option.

     (b) The Participant has reviewed with the Participant's own tax advisors
the federal, state, local and foreign tax consequences of this investment and
the transactions contemplated by this Agreement. The Participant is relying
solely on such advisors and not on any statements or representations of the
Company or any of its agents. The Participant understands that the Participant
(and not the Company) shall be responsible for the Participant's own tax
liability that may arise as a result of this investment or the transactions
contemplated by this Agreement. The Participant understands that it may be
beneficial in many circumstances to elect to be taxed at the time the Shares are
purchased rather than when and as the Company's Purchase Option expires by
filing an election under Section 83(b) of the Code with the I.R.S. within 30
days from the date of purchase.

          THE PARTICIPANT ACKNOWLEDGES THAT IT IS THE PARTICIPANT'S SOLE
RESPONSIBILITY AND NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION
83(b), EVEN IF THE PARTICIPANT REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO
MAKE THIS FILING ON THE PARTICIPANT'S BEHALF.

     12. No Rights to Employment.

     The Participant acknowledges and agrees that the vesting of the Shares
pursuant to Section 2 hereof is earned only by continuing service as an employee
at the will of the Company (not through the act of being hired or purchasing
shares hereunder). The Participant further acknowledges and agrees that the
transactions contemplated hereunder and the vesting schedule set forth herein do
not constitute an express or implied promise of continued engagement as an
employee or consultant for the vesting period, for any period, or at all.

     13. Miscellaneous.

     (a) Severability. The invalidity or unenforceability of any provision of
this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement, and each other provision of this Agreement shall be
severable and enforceable to the extent permitted by law.

     (b) Waiver. Any provision for the benefit of the Company contained in this
Agreement may be waived, either generally or in any particular instance, by the
Board of Directors of the Company.

     (c) Binding Effect. This Agreement shall be binding upon and inure to the
benefit of the Company and the Participant and their respective heirs,
executors, administrators, legal representatives, successors and assigns,
subject to the restrictions on transfer set forth in Sections 4 and 5 of this
Agreement.

                                      -7-

its respective signature to this Agreement, or at such other address or
addresses as either party shall designate to the other in accordance with this
Section 13(d).

     (e) Pronouns. Whenever the context may require, any pronouns used in this
Agreement shall include the corresponding masculine, feminine or neuter forms,

versa.

agreement between the parties, and supersedes all prior agreements and
understandings, relating to the subject matter of this Agreement.

     (g) Amendment. This Agreement may be amended or modified only by a written
instrument executed by both the Company and the Participant.

     (h) Governing Law. This Agreement shall be construed, interpreted and
enforced in accordance with the internal laws of the State of Delaware without
regard to any applicable conflicts of laws.

     (i) Participant's Acknowledgments. The Participant acknowledges that he or
she: (i) has read this Agreement; (ii) has been represented in the preparation,
negotiation, and execution of this Agreement by legal counsel of the
Participant's own choice or has voluntarily declined to seek such counsel; (iii)
understands the terms and consequences of this Agreement; (iv) is fully aware of
the legal and binding effect of this Agreement; and (v) understands that the law
firm of Hale and Dorr LLP, is acting as counsel to the Company in connection
with the transactions contemplated by the Agreement, and is not acting as
counsel for the Participant.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the day and year first above written.
