EXHIBIT 10.28

                     EXECUTIVE CHANGE OF CONTROL AGREEMENT

     This EXECUTIVE CHANGE OF CONTROL AGREEMENT ("Agreement") is made as of the
1st day of August, 2001, between CIRCOR, Inc., a Massachusetts corporation (the
"Company"), and Paul M. Coppinger ("Executive").

     WHEREAS, the Company presently employs the Executive in which capacity the
Executive serves as a divisional officer of the Company and its Parent (as
defined below); and

     WHEREAS, the Board of Directors of the Parent (the "Board") recognizes the
valuable services rendered to the Company, the Parent and their respective
affiliates by the Executive; and

     WHEREAS, the Board has determined that it is in the best interests of the
Company, the Parent and their affiliates to encourage in advance the continued
loyalty of the Executive as well as the Executive's continued attention to his
assigned duties and objectivity in the event of a threatened or possible change
in control of the Parent;

     NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained and other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties agree as follows:

1.  DEFINITIONS.  For purposes of this Agreement, the following terms shall have
the following meanings:

"Cause" shall mean:  (a) conduct by Executive constituting a material act of
willful misconduct in connection with the performance of his duties, including,
without limitation, misappropriation of funds or property of the Company or any
of its affiliates other than the occasional, customary and de minimis use of
Company property for personal purposes; (b) criminal or civil conviction of
Executive, a plea of nolo contendere by Executive or conduct by Executive that
would reasonably be expected to result in material injury to the reputation of
the Company if he were retained in his position with the Company, including,
without limitation, conviction of a felony involving moral turpitude; (c)
continued, willful and deliberate non-performance by Executive of his duties
hereunder (other than by reason of Executive's physical or mental illness,
incapacity or disability) which has continued for more than thirty (30) days
following written notice of such non-performance from the Chief Executive
Officer; or (d) a violation by Executive of the Company's employment policies
which has continued following written notice of such violation from the Chief
Executive Officer.

"CHANGE IN CONTROL" shall mean any of the following:

(a) Any "person," as such term is used in Sections 13(d) and 14(d) of the
Securities Exchange Act of 1934, as amended (the "Act") (other than the Parent,
any of its subsidiaries, any member of the Horne Family Group (as defined
herein) or any trustee, fiduciary or other person or entity holding securities
under any employee benefit plan or trust of the Parent or any of its
subsidiaries), together with all "affiliates" and "associates" (as such terms
are defined in Rule 12b-2 under the Act) of such person, shall become the
"beneficial owner" (as such term is defined in Rule 13d-3 under the Act),
directly or indirectly, of securities of the Parent representing twenty-five
percent (25%) or more of either (A) the combined voting power of the Parent's
then outstanding securities having the right to vote in an election of the
Parent's Board ("Voting Securities") or (B) the then outstanding shares of
Parent's common stock, par value $0.01 per share ("Common Stock") (other than as
a result of an acquisition of securities directly from the Parent); or

(b) Incumbent Directors (as defined below) cease for any reason, including,
without limitation, as a result of a tender offer, proxy contest, merger or
similar transaction, to constitute at least a majority of the Board; or

(c) The stockholders of the Parent shall approve (A) any consolidation or merger
of the Parent where the stockholders of the Parent, immediately prior to the
consolidation or merger, would not, immediately after the consolidation or
merger, beneficially own (as such term is defined in Rule 13d-3 under the Act),
directly or indirectly, shares representing in the aggregate fifty percent (50%)
or more of the voting shares of the Parent or other party issuing cash or
securities in the consolidation or merger (or of its ultimate parent
corporation, if any), (B) any sale, lease, exchange or other transfer (in one
transaction or a series of transactions contemplated or arranged by any party as
a single plan) of all or substantially all of the assets of the Parent or (C)
any plan or proposal for the liquidation or dissolution of the Parent.

     Notwithstanding the foregoing, a "Change of Control" shall not be deemed to
have occurred for purposes of the foregoing clause (a) solely as the result of
an acquisition of securities by the Parent which, by reducing the number of
shares of Common Stock or other Voting Securities outstanding, increases the
proportionate number of shares beneficially owned by

                                       1
<PAGE>

any person to twenty-five percent (25%) or more of either (A) the combined
voting power of all of the then outstanding Voting Securities or (B) Common
Stock; provided, however, that if any person referred to in this sentence shall
thereafter become the beneficial owner of any additional shares of Voting
Securities or Common Stock (other than pursuant to a stock split, stock
dividend, or similar transaction or as a result of an acquisition of securities
directly from the Parent) and immediately thereafter beneficially owns twenty-
five percent (25%) or more of either (A) the combined voting power of all of the
then outstanding Voting Securities or (B) Common Stock, then a "Change of
Control" shall be deemed to have occurred for purposes of the foregoing clause
(a).

"GOOD REASON" shall mean that Executive has complied with the "Good Reason
Process" (hereinafter defined) following the occurrence of any of the following
events:  (a) a substantial diminution or other substantive adverse change, not
consented to by Executive, in the nature or scope of Executive's
responsibilities, authorities, powers, functions or duties; (b) any removal,
during the term of this Agreement from Executive of his titles as an officer of
the Parent; (c) an involuntary reduction in Executive's Base Salary except for
across-the-board reductions similarly affecting all or substantially all
management employees; (d) a breach by the Company of any of its other material
obligations under this Agreement and the failure of the Company to cure such
breach within thirty (30) days after written notice thereof by Executive; or (e)
the involuntary relocation of the Company's offices at which Executive is
principally employed or the involuntary relocation of the offices of Executive's
primary workgroup to a location more than thirty (30) miles from such offices,
or the requirement by the Company that Executive be based anywhere other than
the Company's offices at such location on an extended basis, except for required
travel on the Company's business to an extent substantially consistent with
Executive's business travel obligations.  "Good Reason Process" shall mean that
(i) Executive reasonably determines in good faith that a "Good Reason" event has
occurred; (ii) Executive notifies the Company in writing of the occurrence of
the Good Reason event; (iii) Executive cooperates in good faith with the
Company's efforts, for a period not less than ninety (90) days following such
notice, to modify Executive's employment situation in a manner acceptable to
Executive and Company; and (iv) notwithstanding such efforts, one or more of the
Good Reason events continues to exist and has not been modified in a manner
acceptable to Executive.  If the Company cures the Good Reason event in a manner
acceptable to Executive during the ninety (90) day period, Good Reason shall be
deemed not to have occurred.

"INCUMBENT DIRECTORS" shall mean persons who, as of the Commencement Date,
constitute the Board; provided that any person becoming a director of the Parent
subsequent to the Commencement Date shall be considered an Incumbent Director if
such person's election was approved by or such person was nominated for election
by a vote of at least a majority of the Incumbent Directors; but provided
further, that any such person whose initial assumption of office is in
connection with an actual or threatened election contest relating to the
election of members of the Board or other actual or threatened solicitation of
proxies or consents by or on behalf of a person other than the Board, including
by reason of agreement intended to avoid or settle any such actual or threatened
contest or solicitation, shall not be considered an Incumbent Director.

"PARENT" shall mean CIRCOR International, Inc., a Delaware corporation as well
as its successors by merger or otherwise.

"HORNE FAMILY GROUP" shall mean Timothy P. Horne and the George B. Horne Voting
Trust.

2.  Term.  The term of this Agreement shall extend from the date hereof (the
"Commencement Date") until the first anniversary of the Commencement Date;
provided, however, that the term of this Agreement shall automatically be
extended for one additional year on the first anniversary of the Commencement
Date and each anniversary thereafter unless, not less than 90 days prior to each
such date, either party shall have given notice to the other that it does not
wish to extend this Agreement; provided, further, that if a Change in Control
occurs during the original or extended term of this Agreement, the term of this
Agreement shall continue in effect for a period of not less than twelve (12)
months beyond the month in which the Change in Control occurred.

3.  CHANGE IN CONTROL PAYMENT.  The provisions of this Paragraph 3 set forth
certain terms of an agreement reached between Executive and the Company
regarding Executive's rights and obligations upon the occurrence of a Change in
Control of the Parent.  These provisions are intended to assure and encourage in
advance Executive's continued attention and dedication to his assigned duties
and his objectivity during the pendency and after the occurrence of any such
event.  These provisions shall terminate and be of no further force or effect
beginning twelve (12) months after the occurrence of a Change of Control.

(a)  CHANGE IN CONTROL.

     (i)   If within twelve (12) months after the occurrence of the first event
constituting a Change in Control, Executive's employment is terminated by the
Company without Cause as defined in Section 1 or Executive terminates his

                                       2
<PAGE>

employment for Good Reason as provided in Section 1, then the Company shall pay
Executive a lump sum in cash in an amount equal to one (1) times the sum of (A)
Executive's current Base Salary plus (B) Executive's most recent annual
incentive compensation under the Company's Executive Bonus Incentive Plan for
the most recent fiscal year, excluding any sign-on bonus, retention bonus or any
other special bonus; and

     (ii)   Notwithstanding anything to the contrary in any applicable option
agreement or stock-based award agreement, upon a Change in Control, all stock
options and other stock-based awards granted to Executive by the Parent shall
immediately accelerate and become exercisable or non-forfeitable as of the
effective date of such Change in Control.  In addition, all restricted stock
units held by the Executive pursuant to the Management Stock Purchase Plan shall
become fully vested upon a Change of Control and the Executive shall be entitled
to receive the shares of stock represented by such restricted stock units.
Executive shall also be entitled to any other rights and benefits with respect
to stock-related awards, to the extent and upon the terms provided in the
employee stock option or incentive plan or any agreement or other instrument
attendant thereto pursuant to which such options or awards were granted; and

     (iii)  If the Executive is otherwise eligible for participation in the
Company's Supplemental Executive Retirement Plan ("SERP"), the Executive shall
be fully vested in his accrued benefit under the SERP as of the Date of
Termination; and

     (iv)   The Company shall, for a period of one (1) year commencing on the
Date of Termination, pay such health insurance premiums as may be necessary to
allow Executive, Executive's spouse and dependents to continue to receive health
insurance coverage substantially similar to the coverage they received prior to
the Date of Termination.

(b)  ADDITIONAL LIMITATION.

     (i)   Anything in this Agreement to the contrary notwithstanding, in the
     event that any compensation, payment or distribution by the Company to or
     for the benefit of Executive, whether paid or payable or distributed or
     distributable pursuant to the terms of this Agreement or otherwise (the
     "Severance Payments"), would be subject to the excise tax imposed by
     Section 4999 of the Internal Revenue Code of 1986, as amended (the "Code"),
     the following provisions shall apply:

           (A) If the Severance Payments, reduced by the sum of (1) the Excise
     Tax and (2) the total of the Federal, state and local income and employment
     taxes payable by Executive on the amount of the Severance Payments which
     are in excess of the Threshold Amount, are greater than or equal to the
     Threshold Amount, Executive shall be entitled to the full benefits payable
     under this Agreement.

           (B) If the Threshold Amount is less than (x) the Severance Payments,
     but greater than (y) the Severance Payments reduced by the sum of (1) the
     Excise Tax and (2) the total of the Federal, state, and local income and
     employment taxes on the amount of the Severance Payments which are in
     excess of the Threshold Amount, then the benefits payable under this
     Agreement shall be reduced (but not below zero) to the extent necessary so
     that the maximum Severance Payments shall not exceed the Threshold Amount.
     To the extent that there is more than one method of reducing the payments
     to bring them within the Threshold Amount, Executive shall determine which
     method shall be followed; provided that if Executive fails to make such
     determination within 45 days after the Company has sent Executive written
     notice of the need for such reduction, the Company may determine the amount
     of such reduction in its sole discretion.

     For the purposes of this Paragraph 3, "Threshold Amount" shall mean three
     times Executive's "base amount" within the meaning of Section 280G(b)(3) of
     the Code and the regulations promulgated thereunder less one dollar
     ($1.00); and "Excise Tax" shall mean the excise tax imposed by Section 4999
     of the Code, and any interest or penalties incurred by Executive with
     respect to such excise tax.

     (ii)  The determination as to which of the alternative provisions of
     Paragraph 3(b)(i) shall apply to Executive shall be made by KPMG LLP or any
     other nationally recognized accounting firm selected by the Company (the
     "Accounting Firm"), which shall provide detailed supporting calculations
     both to the Company and Executive within 15 business days of the Date of
     Termination, if applicable, or at such earlier time as is reasonably
     requested by the Company or Executive.  For purposes of determining which
     of the alternative provisions of Paragraph 3(b)(i) shall apply, Executive
     shall be deemed to pay federal income taxes at the highest marginal rate of
     federal income taxation applicable to individuals for the calendar year in
     which the determination is to be made, and state and local income taxes at
     the highest marginal rates of individual taxation in the state and locality
     of Executive's residence on the Date of Termination, net of the maximum
     reduction in federal income taxes which could be obtained from deduction of

                                       3
<PAGE>

     such state and local taxes.  Any determination by the Accounting Firm shall
     be binding upon the Company and Executive.

4.   UNAUTHORIZED DISCLOSURE. Executive acknowledges that in the course of his
employment with the Company (and, if applicable, its predecessors), he has been
allowed to become, and will continue to be allowed to become, acquainted with
the Company's and the Parent's business affairs, information, trade secrets, and
other matters which are of a proprietary or confidential nature, including but
not limited to the Company's, the Parent's and their affiliates' and
predecessors' operations, business opportunities, price and cost information,
finance, customer information, business plans, various sales techniques,
manuals, letters, notebooks, procedures, reports, products, processes, services,
and other confidential information and knowledge (collectively the "Confidential
Information") concerning the Company's, the Parent's and their affiliates' and
predecessors' business. The Company agrees to provide on an ongoing basis such
Confidential Information as the Company deems necessary or desirable to aid
Executive in the performance of his duties. Executive understands and
acknowledges that such Confidential Information is confidential, and he agrees
not to disclose such Confidential Information to anyone outside the Company or
the Parent except to the extent that (i) Executive deems such disclosure or use
reasonably necessary or appropriate in connection with performing his duties on
behalf of the Company and the Parent, (ii) Executive is required by order of a
court of competent jurisdiction (by subpoena or similar process) to disclose or
discuss any Confidential Information, provided that in such case, Executive
shall promptly inform the Company or the Parent, as appropriate, of such event,
shall cooperate with the Company or the Parent, as appropriate, in attempting to
obtain a protective order or to otherwise restrict such disclosure, and shall
only disclose Confidential Information to the minimum extent necessary to comply
with any such court order; (iii) such Confidential Information becomes generally
known to and available for use in the Company's industry (the "Fluid-Control
Industry"), other than as a result of any action or inaction by Executive; or
(iv) such information has been rightfully received by a member of the Fluid-
Control Industry or has been published in a form generally available to the
Fluid-Control Industry prior to the date Executive proposes to disclose or use
such information. Executive further agrees that he will not during employment
and/or at any time thereafter use such Confidential Information in competing,
directly or indirectly, with the Company or the Parent. At such time as
Executive shall cease to be employed by the Company, he will immediately turn
over to the Company or the Parent, as appropriate, all Confidential Information,
including papers, documents, writings, electronically stored information, other
property, and all copies of them provided to or created by him during the course
of his employment with the Company. The provisions of this Paragraph 4 shall
survive termination of this Agreement for any reason.

5.   COVENANT NOT TO COMPETE. In consideration of the benefits afforded the
Executive under the terms provided in this Agreement and as a means to aid in
the performance and enforcement of the terms of the provisions of Paragraph 4,
Executive agrees that

(A) during the term of Executive's employment with the Company and for a period
of twelve (12) months thereafter, regardless of the reason for termination of
employment, Executive will not, directly or indirectly, as an owner, director,
principal, agent, officer, employee, partner, consultant, servant, or otherwise,
carry on, operate, manage, control, or become involved in any manner with any
business, operation, corporation, partnership, association, agency, or other
person or entity which is engaged in a business that is competitive with any of
the Company's or the Parent's products which are produced by the Company or the
Parent or any affiliate of either entity as of the date of Executive's
termination of employment with the Company, in any area or territory in which
the Company or the Parent or any affiliate of either entity conducts operations;
provided, however, that the foregoing shall not prohibit Executive from owning
up to one percent (1%) of the outstanding stock of a publicly held company
engaged in the Fluid-Control Industry; and

(B) during the term of Executive's employment with the Company and for a period
of twelve (12) months thereafter, regardless of the reason for termination of
employment, Executive will not directly or indirectly solicit or induce any
present or future employee of the Company or the Parent or any affiliate of
either entity to accept employment with Executive or with any business,
operation, corporation, partnership, association, agency, or other person or
entity with which Executive may be associated, and Executive will not employ or
cause any business, operation, corporation, partnership, association, agency, or
other person or entity with which Executive may be associated to employ any
present or future employee of the Company or the Parent without providing the
Company or the Parent, as appropriate, with ten (10) days' prior written notice
of such proposed employment.

Should Executive violate any of the provisions of this Paragraph, then in
addition to all other rights and remedies available to the Company at law or in
equity, the duration of this covenant shall automatically be extended for the
period of time from which Executive began such violation until he permanently
ceases such violation.

6.   NOTICE. For purposes of this Agreement, notices and all other
communications provided for in the Agreement shall be in writing and shall be
deemed to have been duly given when delivered or mailed by United States
certified mail, return receipt requested, postage prepaid, addressed as follows:

     if to the Executive:

          At his home address as shown
          in the Company's personnel records;

     if to the Company:

          CIRCOR, Inc.
          35 Corporate Drive
          Burlington, MA 01803
          Attention:  Board of Directors of CIRCOR International, Inc.

or to such other address as either party may have furnished to the other in
writing in accordance herewith, except that notices of change of address shall
be effective only upon receipt.

7.   NOT AN EMPLOYMENT CONTRACT. This Agreement is intended only to provide
those benefits for the Executive as set forth in Paragraph 3 in connection with
a Change of Control. As such, this Agreement is not intended to and does not in
any way constitute an employment agreement or other contract which would cause
the employee to be considered anything other than an employee at will or to in
any way be entitled to any specific payments or benefits from the Company in the
event of a termination of employment not subject to Paragraph 3 of this
Agreement.

8.   MISCELLANEOUS. No provisions of this Agreement may be modified, waived, or
discharged unless such waiver, modification, or discharge is agreed to in
writing and signed by Executive and such officer of the Company as may be
specifically designated by the Board. No waiver by either party hereto of, or
compliance with, any condition or provision of this Agreement to be performed by
such other party shall be deemed a waiver of similar or dissimilar provisions or
conditions at the same or at any prior or subsequent time. No agreements or
representations, oral or otherwise, express or implied, unless specifically
referred to herein, with respect to the subject matter hereof have been made by
either party which are not set forth expressly in this Agreement. The validity,
interpretation, construction, and performance of this Agreement shall be
governed by the laws of the Commonwealth of Massachusetts (without regard to
principles of conflicts of laws).

9.   VALIDITY. The invalidity or unenforceability of any provision or provisions
of this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement, which shall remain in full force and effect. The
invalid portion of this Agreement, if any, shall be modified by any court having
jurisdiction to the extent necessary to render such portion enforceable.

10.  COUNTERPARTS. This Agreement may be executed in several counterparts, each
of which shall be deemed to be an original but all of which together will
constitute one and the same instrument.

11.  ARBITRATION; OTHER DISPUTES. In the event of any dispute or controversy
arising under or in connection with this Agreement, the parties shall first
promptly try in good faith to settle such dispute or controversy by mediation
under the applicable rules of the American Arbitration Association before
resorting to arbitration. In the event such dispute or controversy remains
unresolved in whole or in part for a period of thirty (30) days after it arises,
the parties will settle any remaining dispute or controversy exclusively by
arbitration in Boston, Massachusetts, in accordance with the rules of the
American Arbitration Association then in effect. Judgment may be entered on the
arbitrator's award in any court having jurisdiction. Notwithstanding the above,
the Company shall be entitled to seek a restraining order or injunction in any
court of competent jurisdiction to prevent any continuation of any violation of
Paragraph 4 or 5 hereof.

12. LITIGATION AND REGULATORY COOPERATION. During and after Executive's
employment, Executive shall reasonably cooperate with the Company and the Parent
in the defense or prosecution of any claims or actions now in existence or which
may be brought in the future against or on behalf of the Company and/or the
Parent which relate to events or occurrences that transpired while Executive was
employed by the Company; provided, however, that such cooperation shall not
materially and adversely affect Executive or expose Executive to an increased
probability of civil or criminal litigation. Executive's cooperation in
connection with such claims or actions shall include, but not be limited to,
being available to meet with counsel to prepare for discovery or trial and to
act as a witness on behalf of the Company and/or the

                                       5
<PAGE>

Parent at mutually convenient times. During and after Executive's employment,
Executive also shall cooperate fully with the Company and the Parent in
connection with any investigation or review of any federal, state or local
regulatory authority as any such investigation or review relates to events or
occurrences that transpired while Executive was employed by the Company. The
Company shall also provide Executive with compensation on an hourly basis (to be
derived from the sum of his Base Compensation and Average Incentive
Compensation) for requested litigation and regulatory cooperation that occurs
after his termination of employment, and reimburse Executive for all costs and
expenses incurred in connection with his performance under this Paragraph 12,
including, but not limited to, reasonable attorneys' fees and costs.

13. GENDER NEUTRAL. Wherever used herein, a pronoun in the masculine gender
shall be considered as including the feminine gender unless the context clearly
indicates otherwise.

     IN WITNESS WHEREOF, the parties have executed this Agreement effective on
the date and year first above written.

                           -------------------------

1.  Purpose

     The purpose of this 2001 Stock Incentive Plan (the "Plan") of PAREXEL
International Corporation, a Massachusetts corporation (the "Company"), is to
advance the interests of the Company's stockholders by enhancing the Company's
ability to attract, retain and motivate persons who make (or are expected to
make) important contributions to the Company by providing such persons with
equity ownership opportunities and performance-based incentives and thereby
better aligning the interests of such persons with those of the Company's
stockholders.  Except where the context otherwise requires, the term "Company"
shall include any of the Company's present or future parent or subsidiary
corporations as defined in Sections 424(e) or (f) of the Internal Revenue Code
of 1986, as amended, and any regulations promulgated thereunder (the "Code") and
any other business venture (including, without limitation, joint venture or
limited liability company) in which the Company has a significant interest, as
determined by the Board of Directors of the Company (the "Board").

2.   Eligibility

     All of the Company's employees, officers, directors, consultants and
advisors (and any individuals who have accepted an offer for employment) are
eligible to be granted options (each, an "Award") under the Plan.  Each person
who has been granted an Award under the Plan shall be deemed a "Participant".

3.   Administration and Delegation

(a)  Administration by Board of Directors.  The Plan will be administered by the
     Board.  The Board shall have authority to grant Awards and to adopt, amend
     and repeal such administrative rules, guidelines and practices relating to
     the Plan as it shall deem advisable.  The Board may correct any defect,
     supply any omission or reconcile any inconsistency in the Plan or any Award
     in the manner and to the extent it shall deem expedient to carry the Plan
     into effect and it shall be the sole and final judge of such expediency.
     All decisions by the Board shall be made in the Board's sole discretion and
     shall be final and binding on all persons having or claiming any interest
     in the Plan or in any Award.  No director or person acting pursuant to the
     authority delegated by the Board shall be liable for any action or
     determination relating to or under the Plan made in good faith.

(b)  Appointment of Committees. To the extent permitted by applicable law, the
     Board may delegate any or all of its powers under the Plan to one or more
     committees or subcommittees of the Board (a "Committee").  All references
     in the Plan to the "Board" shall mean the Board or a Committee of the Board
     to the extent that the Board's powers or authority under the Plan have been
     delegated to such Committee.  While the common stock, $0.01 par value per
     share, of the Company (the "Common Stock") is registered under the
     Securities Exchange Act of 1934, as amended or replaced from time to time
     (the "Exchange Act"), the Board shall appoint one such Committee of not
     less than two members, each member of which shall be an "outside director"
     within the meaning of Section 162(m) of the Code ("Section 162(m)") and a
     "non-employee director" as defined in Rule 16b-3 promulgated under the
     Exchange Act.

4.  Stock Available for Awards

(a)  Number of Shares.  Subject to adjustment under Section 6, Awards may be
     made under the Plan for up to 1,000,000 shares of Common Stock.  If any
     Award expires or is terminated, surrendered or canceled without having been
     fully exercised or is forfeited in whole or in part (including as the
     result of shares of Common Stock subject to such Award being repurchased by
     the Company at the original issuance price pursuant to a contractual
     repurchase right) or results in any Common Stock not being issued,

<PAGE>

     the unused Common Stock covered by such Award shall again be available for
     the grant of Awards under the Plan, subject, however, in the case of
     Incentive Stock Options (as hereinafter defined), to any limitations under
     the Code. Shares issued under the Plan may consist in whole or in part of
     authorized but unissued shares or treasury shares.

(b)  Per-Participant Limit.  Subject to adjustment under Section 6 the maximum
     number of shares of Common Stock with respect to which Awards may be
     granted to any Participant under the Plan shall be 500,000 per calendar
     year.  The per-Participant limit described in this Section 4(b) shall be
     construed and applied consistently with Section 162(m).

5.  Stock Options

(a)  General.  The Board may grant options to purchase Common Stock (each, an
     "Option") and determine the number of shares of Common Stock to be covered
     by each Option, the exercise price of each Option and the conditions and
     limitations applicable to the exercise of each Option, including conditions
     relating to applicable federal or state securities laws, as it considers
     necessary or advisable.  An Option which is not intended to be an Incentive
     Stock Option (as hereinafter defined) shall be designated a "Nonstatutory
     Stock Option".

(b)  Incentive Stock Options.  An Option that the Board intends to be an
     "incentive stock option" as defined in Section 422 of the Code (an
     "Incentive Stock Option") shall only be granted to employees of the Company
     and shall be subject to and shall be construed consistently with the
     requirements of Section 422 of the Code.  The Company shall have no
     liability to a Participant, or any other party, if an Option (or any part
     thereof) which is intended to be an Incentive Stock Option is not an
     Incentive Stock Option.

(c)  Exercise Price. The Board shall establish the exercise price at the time
     each Option is granted and specify it in the applicable option agreement,
     provided, however, that the exercise price shall not be less than 100% of
     the fair market value of the Common Stock, as determined by (or in a manner
     approved by) the Board in good faith ("Fair Market Value") at the time the
     Option is granted.

(d)  Duration of Options. Each Option shall be exercisable at such times and
     subject to such terms and conditions as the Board may specify in the
     applicable option agreement, provided, however, that no Option shall be
     granted for a term in excess of 10 years.

(e)  Exercise of Option.  Options may be exercised by delivery to the Company of
     a written notice of exercise signed by the proper person or by any other
     form of notice (including electronic notice) approved by the Board together
     with payment in full as specified in Section 5(f) for the number of shares
     for which the Option is exercised.

(f)  Payment Upon Exercise.  Common Stock purchased upon the exercise of an
     Option granted under the Plan shall be paid for as follows:

          (1)  in cash or by check, payable to the order of the Company;

          (2)  except as the Board may, in its sole discretion, otherwise
               provide in an option agreement, by (i) delivery of an irrevocable
               and unconditional undertaking by a creditworthy broker to deliver
               promptly to the Company sufficient funds to pay the exercise
               price and any required tax withholding or (ii) delivery by the
               Participant to the Company of a copy of irrevocable and
               unconditional instructions to a creditworthy broker to deliver
               promptly to the Company cash or a check sufficient to pay the
               exercise price and any required tax withholding;

          (3)  by delivery of shares of Common Stock owned by the Participant
               valued at their Fair Market Value, provided (i) such method of
               payment is then permitted under applicable law and (ii) such
               Common Stock, if acquired directly from the Company was owned by
               the Participant at least six months prior to such delivery;

          (4)  to the extent permitted by the Board, in its sole discretion by
               (i) delivery of a promissory note of the Participant to the
               Company on terms determined by the Board, or (ii) payment of such
               other lawful consideration as the Board may determine; or

          (5)  by any combination of the above permitted forms of payment.

                                      -2-
<PAGE>

(g)  Substitute Options.  In connection with a merger or consolidation of an
     entity with the Company or the acquisition by the Company of property or
     stock of an entity, the Board may grant Options in substitution for any
     options or other stock or stock-based awards granted by such entity or an
     affiliate thereof.  Substitute Options may be granted on such terms as the
     Board deems appropriate in the circumstances, notwithstanding any
     limitations on Options contained in the other sections of this Section 5 or
     in Section 2.

6.   Adjustments for Changes in Common Stock and Certain Other Events

(a)  Changes in Capitalization.  In the event of any stock split, reverse stock
     split, stock dividend, recapitalization, combination of shares,
     reclassification of shares, spin-off or other similar change in
     capitalization or event, or any distribution to holders of Common Stock
     other than a normal cash dividend, (i) the number and class of securities
     available under this Plan, (ii) the per-Participant limit set forth in
     Section 4(b), and (iii) the number and class of securities and exercise
     price per share subject to each outstanding Option shall be appropriately
     adjusted by the Company (or substituted Awards may be made, if applicable)
     to the extent the Board shall determine in good faith that such an
     adjustment or substitution is necessary and appropriate.  If this Section
     6(a) applies and Section 6(c) also applies to any event, Section 6(c) shall
     be applicable to such event, and this Section 6(a) shall not be applicable.

(b)  Liquidation or Dissolution.  In the event of a proposed liquidation or
     dissolution of the Company, the Board shall upon written notice to the
     Participants provide that all then unexercised Options will (i) become
     exercisable in full as of a specified time at least 10 business days prior
     to the effective date of such liquidation or dissolution and (ii) terminate
     effective upon such liquidation or dissolution, except to the extent
     exercised before such effective date.

(c)  Reorganization Events

     (1)  Definition. A "Reorganization Event" shall mean: (a) any merger or
          consolidation of the Company with or into another entity as a result
          of which all of the Common Stock of the Company is converted into or
          exchanged for the right to receive cash, securities or other property
          or (b) any exchange of all of the Common Stock of the Company for
          cash, securities or other property pursuant to a share exchange
          transaction.

     (2)  Consequences of a Reorganization Event on Options. Upon the occurrence
          of a Reorganization Event, or the execution by the Company of any
          agreement with respect to a Reorganization Event, the Board shall
          provide that all outstanding Options shall be assumed, or equivalent
          options shall be substituted, by the acquiring or succeeding
          corporation (or an affiliate thereof). For purposes hereof, an Option
          shall be considered to be assumed if, following consummation of the
          Reorganization Event, the Option confers the right to purchase, for
          each share of Common Stock subject to the Option immediately prior to
          the consummation of the Reorganization Event, the consideration
          (whether cash, securities or other property) received as a result of
          the Reorganization Event by holders of Common Stock for each share of
          Common Stock held immediately prior to the consummation of the
          Reorganization Event (and if holders were offered a choice of
          consideration, the type of consideration chosen by the holders of a
          majority of the outstanding shares of Common Stock); provided,
          however, that if the consideration received as a result of the
          Reorganization Event is not solely common stock of the acquiring or
          succeeding corporation (or an affiliate thereof), the Company may,
          with the consent of the acquiring or succeeding corporation, provide
          for the consideration to be received upon the exercise of Options to
          consist solely of common stock of the acquiring or succeeding
          corporation (or an affiliate thereof) equivalent in fair market value
          to the per share consideration received by holders of outstanding
          shares of Common Stock as a result of the Reorganization Event.

     Notwithstanding the foregoing, if the acquiring or succeeding corporation
(or an affiliate thereof) does not agree to assume, or substitute for, such
Options, then the Board shall, upon written notice to the Participants, provide
that all then unexercised Options will terminate immediately prior to the
consummation of such Reorganization Event, except to the extent exercised by the
Participants before the consummation of such Reorganization Event; provided,
however, that in the event of a Reorganization Event under the terms of which
holders of Common Stock will receive upon consummation thereof a cash payment
for each share of Common Stock surrendered pursuant to such Reorganization Event
(the "Acquisition Price"), then the Board may instead provide that all
outstanding

                                      -3-
<PAGE>

Options shall terminate upon consummation of such Reorganization Event and that
each Participant shall receive, in exchange therefor, a cash payment equal to
the amount (if any) by which (A) the Acquisition Price multiplied by the number
of shares of Common Stock then exercisable under such outstanding Options,
exceeds (B) the aggregate exercise price of such Options.

7.  General Provisions Applicable to Awards

    (a)  Transferability of Awards. Except as the Board may otherwise determine
         or provide in an Award, Awards shall not be sold, assigned,
         transferred, pledged or otherwise encumbered by the person to whom they
         are granted, either voluntarily or by operation of law, except by will
         or the laws of descent and distribution, and, during the life of the
         Participant, shall be exercisable only by the Participant. References
         to a Participant, to the extent relevant in the context, shall include
         references to authorized transferees.

    (b)  Documentation. Each Award shall be evidenced in such form (written,
         electronic or otherwise) as the Board shall determine. Each Award may
         contain terms and conditions in addition to those set forth in the
         Plan.

    (c)  Board Discretion. Except as otherwise provided by the Plan, each Award
         may be made alone or in addition or in relation to any other Award. The
         terms of each Award need not be identical, and the Board need not treat
         Participants uniformly.

    (d)  Termination of Status. The Board shall determine the effect on an Award
         of the disability, death, retirement, authorized leave of absence or
         other change in the employment or other status of a Participant and the
         extent to which, and the period during which, the Participant, the
         Participant's legal representative, conservator, guardian or Designated
         Beneficiary may exercise rights under the Award.

    (e)  Withholding. Each Participant shall pay to the Company, or make
         provision satisfactory to the Board for payment of, any taxes required
         by law to be withheld in connection with Awards to such Participant no
         later than the date of the event creating the tax liability. Except as
         the Board may otherwise provide in an Award, Participants may satisfy
         such tax obligations in whole or in part by delivery of shares of
         Common Stock, including shares retained from the Award creating the tax
         obligation, valued at their Fair Market Value; provided, however, that
         the total tax withholding where stock is being used to satisfy such tax
         obligations cannot exceed the Company's minimum statutory withholding
         obligations (based on minimum statutory withholding rates for federal
         and state tax purposes, including payroll taxes, that are applicable to
         such supplemental taxable income). The Company may, to the extent
         permitted by law, deduct any such tax obligations from any payment of
         any kind otherwise due to a Participant.

    (f)  Amendment of Award. The Board may amend, modify or terminate any
         outstanding Award, including but not limited to, substituting therefor
         another Award of the same or a different type, changing the date of
         exercise or realization, and converting an Incentive Stock Option to a
         Nonstatutory Stock Option, provided that the Participant's consent to
         such action shall be required unless the Board determines that the
         action, taking into account any related action, would not materially
         and adversely affect the Participant.

    (g)  Conditions on Delivery of Stock. The Company will not be obligated to
         deliver any shares of Common Stock pursuant to the Plan or to remove
         restrictions from shares previously delivered under the Plan until (i)
         all conditions of the Award have been met or removed to the
         satisfaction of the Company, (ii) in the opinion of the Company's
         counsel, all other legal matters in connection with the issuance and
         delivery of such shares have been satisfied, including any applicable
         securities laws and any applicable stock exchange or stock market rules
         and regulations, and (iii) the Participant has executed and delivered
         to the Company such representations or agreements as the Company may
         consider appropriate to satisfy the requirements of any applicable
         laws, rules or regulations.

    (h)  Acceleration. The Board may at any time provide that any Award shall
         become immediately exercisable in full or in part, free of some or all
         restrictions or conditions, or otherwise realizable in full or in part,
         as the case may be.

    (i)  Limitations on Option Repricings. Except for adjustments pursuant to
         Section 6, the exercise price for any outstanding Option granted under
         the Plan may not be decreased after the date of grant, nor may an
         outstanding Option granted under the Plan be surrendered to the Company
         as consideration for the grant of a new security with a lower exercise
         price, without the prior approval of the Company's stockholders.

                                      -4-

8.  Miscellaneous

    (a)  No Right To Employment or Other Status. No person shall have any claim
         or right to be granted an Award, and the grant of an Award shall not be
         construed as giving a Participant the right to continued employment or
         any other relationship with the Company. The Company expressly reserves
         the right at any time to dismiss or otherwise terminate its
         relationship with a Participant free from any liability or claim under
         the Plan, except as expressly provided in the applicable Award.

    (b)  No Rights As Stockholder. Subject to the provisions of the applicable
         Award, no Participant or Designated Beneficiary shall have any rights
         as a stockholder with respect to any shares of Common Stock to be
         distributed with respect to an Award until becoming the record holder
         of such shares. Notwithstanding the foregoing, in the event the Company
         effects a split of the Common Stock by means of a stock dividend and
         the exercise price of and the number of shares subject to such Option
         are adjusted as of the date of the distribution of the dividend (rather
         than as of the record date for such dividend), then an optionee who
         exercises an Option between the record date and the distribution date
         for such stock dividend shall be entitled to receive, on the
         distribution date, the stock dividend with respect to the shares of
         Common Stock acquired upon such Option exercise, notwithstanding the
         fact that such shares were not outstanding as of the close of business
         on the record date for such stock dividend.

    (c)  Effective Date and Term of Plan. The Plan shall become effective on the
         date on which it is adopted by the Board, but no Award granted to a
         Participant that is intended to comply with Section 162(m) shall become
         exercisable, vested or realizable, as applicable to such Award, unless
         and until the Plan has been approved by the Company's stockholders to
         the extent stockholder approval is required by Section 162(m) in the
         manner required under Section 162(m) (including the vote required under
         Section 162(m)). No Awards shall be granted under the Plan after the
         completion of ten years from the earlier of (i) the date on which the
         Plan was adopted by the Board or (ii) the date the Plan was approved by
         the Company's stockholders, but Awards previously granted may extend
         beyond that date.

    (d)  Amendment of Plan. The Board may amend, suspend or terminate the Plan
         or any portion thereof at any time, provided that to the extent
         required by Section 162(m), no Award granted to a Participant that is
         intended to comply with Section 162(m) after the date of such amendment
         shall become exercisable, realizable or vested, as applicable to such
         Award, unless and until such amendment shall have been approved by the
         Company's stockholders if required by Section 162(m) (including the
         vote required under Section 162(m)), and further provided that the
         provisions of Section 7(i) (relating to Option repricing) cannot be
         amended unless the amendment is approved by the Company's stockholders.

    (e)  Governing Law. The provisions of the Plan and all Awards made hereunder
         shall be governed by and interpreted in accordance with the laws of the
         Commonwealth of Massachusetts, without regard to any applicable
         conflicts of law.
