Exhibit 10.3

                             MERCATOR SOFTWARE, INC.

                           1997 EQUITY INCENTIVE PLAN

       As Adopted May 8, 1997 and Amended July 21, 1997, January 27, 1999,
   March 17, 1999, May 18, 1999, April 3, 2000, June 19, 2000 and May 17, 2001

      1. PURPOSE. The purpose of this Plan is to provide incentives to attract,
retain and motivate eligible persons whose present and potential contributions
are important to the success of the Company, its Parent and Subsidiaries, by
offering them an opportunity to participate in the Company's future performance
through awards of Options, Restricted Stock and Stock Bonuses. Capitalized terms
not defined in the text are defined in Section 23.

      2. SHARES SUBJECT TO THE PLAN.

            2.1 Number of Shares Available. Subject to Sections 2.2 and 18, the
total number of Shares reserved and available for grant and issuance pursuant to
Awards made under this Plan will be 9,700,000 Shares. Subject to Sections 2.2
and 18, Shares will again be available for grant and issuance in connection with
future Awards under the Plan if the shares: (a) are subject to issuance upon
exercise of an Option but cease to be subject to such Option for any reason
other than exercise of such Option; (b) are subject to an Award granted
hereunder but are forfeited or are repurchased by the Company at the original
issue price; or (c) are subject to an Award that otherwise terminates without
Shares being issued. Any authorized shares not issued or subject to outstanding
grants under the Company's 1993 Stock Option Plan (the "Prior Plan") on the
Effective Date (as defined below) and any shares that: (a) are issuable upon
exercise of options granted pursuant to the Prior Plan that expire or become
unexercisable for any reason without having been exercised in full or (b) are
subject to an option granted pursuant to the Prior Plan but are forfeited or are
repurchased by the Company at the original issue price; will no longer be
available for grant and issuance under the Prior Plan, but will be available for
grant and issuance under this Plan. At all times the Company shall reserve and
keep available a sufficient number of Shares as shall be required to satisfy the
requirements of all outstanding Options granted under this Plan and all other
outstanding but unvested Awards granted under this Plan. No Participant may
receive (a) Restricted Stock Awards, (b) Stock Bonus Awards, or (c) Options with
an Exercise Price below Fair Market Value for more than 150,000 Shares over the
term of the Plan, and the sum of such awards issued under this Plan may not
exceed 300,000 Shares in the aggregate over the term of the Plan.

            2.2 Adjustment of Shares. In the event that the number of
outstanding Shares is changed by a stock dividend, recapitalization, stock
split, reverse stock split, subdivision, combination, reclassification or
similar change in the capital structure of the Company without consideration,
then (a) the number of Shares reserved for issuance under this Plan, (b) the
Exercise Prices of and number of Shares subject to outstanding Options, and (c)
the number of Shares subject to other Outstanding Awards will be proportionately
adjusted, subject to any required action by the Board or the stockholders of the
Company and compliance with applicable securities laws; provided, however, that
fractions of a Share will not be issued but will either be replaced by a cash
payment equal to the Fair Market Value of such fraction of a Share or will be
rounded up to the nearest whole Share, as determined by the Committee.


      3. ELIGIBILITY. ISO (as defined in Section 5 below) may be granted only to
employees (including officers and directors who are also employees) of the
Company or of a Parent or Subsidiary of the Company. All other Awards may be
granted to employees, officers, directors, consultants, independent contractors
and advisors of the Company or any Parent or Subsidiary of the Company; provided
such consultants, contractors and advisors render bona fide services not in
connection with the offer and sale of securities in a capital-raising
transaction. No person will be eligible to receive more than 300,000 Shares in
any calendar year under this Plan pursuant to the grant of Awards hereunder,
other than new employees of the Company or of a Parent or Subsidiary of the
Company (including new employees who are also officers and directors of the
Company or any Parent or Subsidiary of the Company) who are eligible to receive
up to a maximum of 1,000,000 Shares in the calendar year in which they commence
their employment. A person may be granted more than one Award under this Plan.

      4. ADMINISTRATION.

            4.1 Committee Authority. This Plan will be administered by the
Committee. Subject to the general purposes, terms and conditions of this Plan,
the Committee will have full power to implement and carry out this Plan. Without
limiting the previous sentence, the Committee will have the authority to:

                  (a) construe and interpret this Plan, any Award Agreement and
any other agreement or document executed pursuant to this Plan;

                  (b) prescribe, amend and rescind rules and regulations
relating to this Plan, including determining the forms and agreements used in
connection with this Plan; provided that the Committee may delegate to the
President and Chief Executive Officer or the Chief Financial Officer, the
authority to approve revisions to the forms and agreements used in connection
with this Plan that are designed to facilitate Plan administration, and that are
not inconsistent with this Plan or with any resolutions of the Committee
relating to this Plan;

                  (c) select persons to receive Awards; provided that the
Committee may delegate to one or more executive officers of the Company who are
also members of the Board, the authority to grant an Award under this Plan to
Participants who are not Insiders of the Company;

                  (d) determine the terms of Awards;

                  (e) determine the number of Shares or other consideration
subject to Awards;

                  (f) determine whether Awards will be granted singly, in
combination or in tandem with, in replacement of or as alternatives to, other
Awards under this Plan or any other incentive or compensation plan of the
Company or any Parent or Subsidiary of the Company;

                  (g) grant waivers of Plan or Award conditions;

                  (h) determine the vesting, exercisability and payment of
Awards;

                  (i) correct any defect, supply any omission or reconcile any
inconsistency in this Plan, any Award or any Award Agreement;

                                       2


                  (j) determine whether an Award has been earned; and

                  (k) amend this Plan, except for amendments that increase the
number of Shares available for issuance under this Plan or change the
eligibility criteria for participation in this Plan, or any other amendments
that would require approval of the stockholders of the Company;

                  (l) make all other determinations necessary or advisable for
the administration of this Plan.

            4.2 Committee Interpretation and Discretion. Any determination made
by the Committee with respect to any Award will be made in its sole discretion
at the time of grant of the Award or, unless in contravention of any express
term of this Plan or Award, at any later time, and such determination will be
final and binding on the Company and on all persons having an interest in any
Award under this Plan. Any dispute regarding the interpretation of this Plan or
any award Agreement shall be submitted by the participant or the Company to the
Committee for review. The resolution of such a dispute by the Committee shall be
final and binding on the Company and the Participant.

      5. OPTIONS. The Committee may grant Options to eligible persons and will
determine whether such Options will be Incentive Stock Options within the
meaning of the Code ("ISO") or Non-Qualified Stock Options ("NQSO"), the number
of Shares subject to the Option, the Exercise Price of the Option, the period
during which the Option may be exercised, and all other terms and conditions of
the Option, subject to the following:

            5.1 Form of Option Grant. Each Option granted under this Plan will
be evidenced by an Award Agreement which will expressly identify the Option as
an ISO or an NQSO ("Stock Option Agreement"). The Stock Option Agreement will be
substantially in a form (which need not be the same for each Participant) that
the Committee or an officer of the Company (pursuant to Section 41(b)) has from
time to time approved, and will comply with and be subject to the terms and
conditions of this Plan.

            5.2 Date of Grant. The date of grant of an Option will be the date
on which the Committee makes the determination to grant such Option, unless a
later date is otherwise specified by the Committee. The Stock Option Agreement
and a copy of this Plan will be delivered to the Participant within a reasonable
time after the granting of the Option.

            5.3 Exercise Period. Options may be exercisable within the times or
upon the occurrence of events determined by the Committee and set forth in the
Stock Option Agreement governing such Option; subject to the provisions of
Section 5.6 and subject to Company policies established by the Committee (or by
individuals to whom the Committee has delegated responsibility) from time to
time with respect to vesting during leaves of absences. No Option will be
exercisable after the expiration of ten (10) years from the date the Option is
granted, provided however that no ISO granted to a person who directly or by
attribution owns more than ten percent (10%) of the total combined voting power
of all classes of stock of the Company or of any Parent or Subsidiary of the
Company ("Ten Percent Stockholder") will be exercisable after the expiration of
five (5) years from the date the ISO is granted. The Committee also may provide
for Options to become exercisable at one time or from time to time, periodically
or otherwise, in such number of Shares or percentage of Shares as the Committee
determines.

            5.4 Exercise Price. The Exercise Price of an Option will be
determined by the Committee when the Option is granted and may not be less than
85% of the Fair Market Value of the Shares on the date of grant; provided that:
(i) the Exercise Price of an ISO will not be less than 100% of the Fair Market
Value of the Shares on the date of grant; and (ii) the Exercise Price of any ISO
granted to a

                                       3


Ten Percent Stockholder will not be less than 110% of the Fair Market Value of
the Shares on the date of grant. Payment for the Shares purchased must be made
in accordance with Section 8 of this Plan and the Stock Option Agreement.

            5.5 Method of Exercise. Options may be exercised only by delivery to
the Company of a written stock option exercise agreement (the "Exercise
Agreement"). The Exercise Agreement will be substantially in a form (which need
not be the same for each Participant), that the Committee or an Officer of the
Company (pursuant to Section 4.1(b)) has from time to time approved and shall
state the number of Shares being purchased, the restriction imposed on the
Shares purchased under such Exercise Agreement, if any, and such representations
and agreements regarding Participant's investment intent and access to
information and other matters, if any, as may be required or desirable by the
Company to comply with applicable securities laws, together with payment in full
of the Exercise Price for the number of shares being purchased.

            5.6 Termination.

                  (a) Termination for Other than Cause. An Option granted to a
Participant will cease to vest on the Participant's Termination. Following the
Participant's Termination, the Participant's Option may be exercised (to the
extent such Option was exercisable immediately prior to the Termination Date):

                        (i) no later than three (3) months after the Termination
Date if the Participant is Terminated for any reason except death or Disability,
unless a shorter or longer time period not exceeding five (5) years is
specifically set forth in the Participant's Stock Option Agreement, provided
that any exercise of an ISO more than three (3) months after the Termination
Date is deemed to be an NQSO, and provided further than no Option may be
exercised later than the expiration date of the Option.

                        (ii) no later than twelve (12) months after the
Termination Date if the Participant is Terminated because of Participant's death
or Disability (or the Participant dies within three (3) months after a
Termination other than because of Participant's death or Disability), unless a
shorter or longer time period not exceeding five (5) years is specifically set
forth in the Participant's Stock Option Agreement; provided that any exercise of
an ISO more than twelve (12) months after the Termination Date when the
Termination is for Participant's Disability is deemed to be an NQSO, and
provided further that no option may be exercised later than the expiration date
of the Option.

                  (b) Termination for Cause. Notwithstanding the provisions in
paragraph 5.6(a) above, if a Participant is determined by the Board to have
committed an act of theft, embezzlement, fraud, dishonesty or a breach of
fiduciary duty to the Company or Subsidiary, neither the Participant, the
Participant's estate nor such other person who may then hold the Option shall be
entitled to exercise any Option with respect to any Shares whatsoever, after
termination of service, whether or not after termination of service the
Participant may receive payment from the Company or Subsidiary for vacation pay,
for services rendered prior to termination, for services rendered for the day on
which termination occurs, for salary in lieu of notice, or for any other
benefits. In making such determination, the Board shall give the Participant an
opportunity to present to the Board evidence on his behalf. For the purpose of
this paragraph, termination of service shall be deemed to occur on the date when
the Company dispatches notice or advice to the Participant that his service is
terminated.

            5.7 Limitations on Exercise. The Committee may specify a reasonable
minimum number of Shares that may be purchased on any exercise of an Option,
provided that such

                                       4


minimum number will not prevent Participant from exercising the Option for the
full number of Shares for which it is then exercisable.

            5.8 Limitations on ISO. The aggregate Fair Market Value (determined
as of the date of giant) of Shares with respect to which ISO are exercisable for
the first time by a Participant during any calendar year (under this Plan or
under any other incentive stock option plan of the Company, Parent or Subsidiary
of the Company) will not exceed $100,000. If the Fair Market Value of Shares on
the date of grant with respect to which ISO are exercisable for the first time
by a Participant during any calendar year exceeds $100,000, then the Options for
the first $100,000 worth of Shares to become exercisable in such calendar year
will be ISO and the Options for the amount in excess of $100,000 that become
exercisable in that calendar year will be NQSO. In the event that the Code or
the regulations promulgated thereunder are amended after the Effective Date of
this Plan to provide for a different limit on the Fair Market Value of Shares
permitted to be subject to ISO, such different limit will be automatically
incorporated herein and will apply to any Options granted after the effective
date of such amendment.

            5.9 Modification, Extension or Renewal. The Committee may modify,
extend or renew outstanding Options and authorize the grant of new Options in
substitution therefor, provided that any such action may not, without the
written consent of a Participant, impair any of such Participant's rights under
any Option previously granted. Any outstanding ISO that is modified, extended,
renewed or otherwise altered will be treated in accordance with Section 424(h)
of the Code. The Committee may reduce the Exercise Price of outstanding Options
without the consent of Participants affected by a written notice to them;
provided, however, that the Exercise Price may not be reduced below the minimum
Exercise Price that would be permitted under Section 5.4 of this Plan for
Options granted on the date the action is taken to reduce the Exercise Price.

            5.10 No Disqualification. Notwithstanding any other provision in
this Plan, no term of this Plan relating to ISO will be interpreted, amended or
altered, nor will any discretion or authority granted under this Plan be
exercised, so as to disqualify this Plan under Section 422 of the Code or,
without the consent of the Participant affected, to disqualify any ISO under
Section 422 of the Code.

      6. RESTRICTED STOCK. A Restricted Stock Award is an offer by the Company
to sell to an eligible person Shares that are subject to restrictions. The
Committee will determine to whom an offer will be made, the number of Shares the
person may purchase, the price to be paid (the "Purchase Price"), the
restrictions to which the Shares will be subject, and all other terms and
conditions of the Restricted Stock Award, subject to the following:

            6.1 Form of Restricted Stock Award. All purchases under a Restricted
Stock Award made pursuant to this Plan will be evidenced by an Award Agreement
("Restricted Stock Purchase Agreement") that will be in such form (which need
not be the same for each Participant) as the Committee will from time to time
approve, and will comply with and be subject to the terms and conditions of this
Plan. The offer of Restricted Stock will be accepted by the Participant's
execution and delivery of the Restricted Stock Purchase Agreement and full
payment for the Shares to the Company within thirty (30) days from the date the
Restricted Stock Purchase Agreement is delivered to the person. If such person
does not execute and deliver the Restricted Stock Purchase Agreement along with
full payment for the Shares to the Company within thirty (30) days, then the
offer will terminate, unless otherwise determined by the Committee.

            6.2 Purchase Price. The Purchase Price of Shares sold pursuant to a
Restricted Stock Award will be determined by the Committee and will be at least
85% of the Fair Market Value of the Shares on the date the Restricted Stock
Award is granted, except in the case of a sale to a Ten

                                       5


Percent Stockholder, in which case the Purchase Price will be 100% of the Fair
Market Value. Payment of the Purchase Price must be made in accordance with
Section 8 of this Plan.

            6.3 Restrictions. Restricted Stock Awards will be subject to such
restrictions (if any) as the Committee may impose. The Committee may provide for
the lapse of such restrictions in installments and may accelerate or waive such
restrictions, in whole or part, based on length of service, performance or such
other factors or criteria as the Committee may determine.

      7. STOCK BONUSES.

            7.1 Awards of Stock Bonuses. A Stock Bonus is an award of Shares
(which may consist of Restricted Stock) for services rendered to the Company or
any Parent or Subsidiary of the Company. A Stock Bonus may be awarded for past
services already rendered to the Company, or any Parent or Subsidiary of the
Company (provided that the Participant pays the Company the par value of the
shares awarded by such Stock Bonus in cash) pursuant to an Award Agreement (the
"Stock Bonus Agreement") that will be in such form (which need not be the same
for each Participant) as the Committee will from time to time approve, and will
comply with and be subject to the terms and conditions of this Plan. A Stock
Bonus may be awarded upon satisfaction of such performance goals as are set out
in advance in the Participant's individual Award Agreement (the "Performance
Stock Bonus Agreement") that will be in such form (which need not be the same
for each Participant) as the Committee will from time to time approve, and will
comply with and be subject to the terms and conditions of this Plan. Stock
Bonuses may vary from Participant to Participant and between groups of
Participants, and may be based upon the achievement of the Company, Parent or
Subsidiary and/or individual performance factors or upon such other criteria as
the Committee may determine.

            7.2 Terms of Stock Bonuses. The Committee will determine the number
of Shares to be awarded to the Participant and whether such Shares will be
Restricted Stock. If the Stock Bonus is being earned upon the satisfaction of
performance goals pursuant to a Performance Stock Bonus Agreement, then the
Committee will determine: (a) the nature, length and starting date of any period
during which performance is to be measured (the "Performance Period") for each
Stock Bonus; (b) the performance goals and criteria to be used to measure the
performance, if any; (c) the number of Shares that may be awarded to the
Participant; and (d) the extent to which such Stock Bonuses have been earned.
Performance Periods may overlap and Participants may participate simultaneously
with respect to Stock Bonuses that are subject to different Performance Periods
and different performance goals and other criteria. The number of Shares may be
fixed or may vary in accordance with such performance goals and criteria as may
be determined by the Committee. The Committee may adjust the performance goals
applicable to the Stock Bonuses to take into account changes in law and
accounting or tax rules and to make such adjustments as the Committee deems
necessary or appropriate to reflect the impact of extraordinary or unusual
items, events or circumstances to avoid windfalls or hardships.

            7.3 Form of Payment. The earned portion of a Stock Bonus may be paid
currently or on a deferred basis with such interest or dividend equivalent, if
any, as the Committee may determine. Payment may be made in the form of cash,
whole Shares, including Restricted Stock, or a combination thereof, either in a
lump sum payment or in installments, all as the Committee will determine.

            7.4 Termination During Performance Period. If a Participant is
Terminated during a Performance Period for any reason, then such Participant
will be entitled to payment (whether in Shares, cash or otherwise) with respect
to the Stock Bonus only to the extent earned as of the date of Termination in
accordance with the Performance Stock Bonus Agreement, unless the Committee will
determine otherwise.

                                       6


      8. PAYMENT FOR SHARE PURCHASES.

            8.1 Payment. Payment for Shares purchased pursuant to this Plan may
be made by any of the following methods (or any combination of such methods)
that are described in the applicable Stock Option Agreement or other Award
Agreement and that are permitted by law:

                  (a) in cash (by check);

                  (b) by cancellation of indebtedness of the Company to the
Participant;

                  (c) by surrender of shares that either: (1) have been owned by
Participant for more than six (6) months and have been paid for within the
meaning of SEC Rule 144 (and, if such shares were purchased from the Company by
use of a promissory note, such note has been fully paid with respect to such
shares); or (2) were obtained by Participant in the public market;

                  (d) by tender of a full recourse promissory note having such
terms as may be approved by the Committee and bearing interest at a rate
sufficient to avoid imputation of income under Sections 483 and 1274 of the
Code; provided, however, that Participants who are not employees or directors of
the Company will not be entitled to purchase Shares with a promissory note
unless the note is adequately secured by collateral other than the Shares;
provided, further, that the portion of the Purchase Price or Exercise Price
equal to the par value of the Shares, if any, must be paid in cash;

                  (e) by waiver of compensation due or accrued to the
Participant for services rendered; provided, however, that the portion of the
Purchase Price or Exercise Price equal to the par value of the Shares, if any,
must be paid in cash; or

                  (f) with respect only to purchases upon exercise of an Option,
and provided that a public market for the Company's stock exists:

                        (1) through a "same day sale" commitment from the
Participant and a broker-dealer that is a member of the National Association of
Securities Dealers (a "NASD Dealer") whereby the Participant irrevocably elects
to exercise the Option and to sell a portion of the Shares so purchased to pay
for the Exercise Price, and whereby the NASD Dealer irrevocably commits upon
receipt of such Shares to forward the Exercise Price directly to the Company; or

                        (2) through a "margin" commitment from the Participant
and a NASD Dealer whereby the Participant irrevocably elects to exercise the
Option and to pledge the Shares so purchased to the NASD Dealer in a margin
account as security for a loan from the NASD Dealer in the amount of the
Exercise Price, and whereby the NASD Dealer irrevocably commits upon receipt of
such Shares to forward the Exercise Price directly to the Company.

            8.2 Loan Guarantees. The Committee may, in its sole discretion, help
the Participant pay for Shares purchased under this Plan by authorizing a
guarantee by the Company of a third-party loan to the Participant.

            8.3 Issuance of Shares. Upon payment of the applicable Purchase
Price or Exercise Price (or a commitment for payment from the NASD Dealer
designated by the Participant in the case of an exercise by means of a "same-day
sale" or "margin" commitment), and compliance with other

                                       7


conditions and procedures established by the Company for the purchase of shares,
the Company shall issue the Shares registered in the name of Participant (or in
the name of the NASD Dealer designated by the Participant in the case of an
exercise by means of a "same-day sale" or "margin" commitment) and shall deliver
certificates representing the Shares (in physical or electronic form, as
appropriate). The Shares may be subject to legends or other restrictions as
described in Section 13 of the Plan.

      9. WITHHHOLDING TAXES.

            9.1 Withholding Genera1ly. Whenever Shares are to be issued under
Awards granted under this Plan, the Company may require the Participant to pay
to the Company an amount sufficient to satisfy federal, state and local
withholding tax requirements prior to the delivery of any certificate(s) for the
Shares. If a payment in satisfaction of an Award is to be made in cash, the
payment will be net of an amount sufficient to satisfy federal, state, and local
withholding tax requirements.

            9.2 Stock Withholding. When, under applicable tax laws, a
Participant incurs tax liability in connection with the exercise or vesting of
any Award that is subject to tax withholding and the Participant is obligated to
pay the Company the amount required to be withheld, the Committee may in its
sole discretion allow the Participant to satisfy the minimum withholding tax
obligation by electing to have the Company withhold from the Shares to be issued
that number of Shares having a Fair Market Value equal to the minimum amount
required to be withheld, determined on the date that the amount of tax to be
withheld is to be determined. All elections by a Participant to have Shares
withheld for this purpose will be made in accordance with the requirements
established by the Committee and must be in writing in a form acceptable to the
Committee

      10. PRIVILEGES OF STOCK OWNERSHIP.

            10.1 Voting and Dividends. No Participant will have any of the
rights of a stockholder of the Company with respect to any Shares until the
Shares are issued to the Participant. After Shares are issued to the
Participant, the Participant will be a stockholder and have all the rights of a
stockholder with respect to the Shares; provided, however, that if the Shares
are Restricted Stock, any new, additional or different securities the
Participant may become entitled to receive with respect to the Shares by virtue
of a stock dividend, stock split or any other change in the corporate or capital
structure of the Company will be subject to the same restrictions as the
Restricted Stock; provided, further, that the Participant will have no right to
retain such stock dividends or stock distributions with respect to Shares that
are repurchased at the Participant's original Purchase Price pursuant to Section
12.

      11. TRANSFERABILITY. Awards granted under this Plan, and any interest
therein, will not be transferable or assignable by Participant, and may not be
made subject to execution, attachment or similar process, otherwise than by will
or by the laws of descent and distribution or as determined by the Committee and
set forth in the Award Agreement with respect to Awards that are not ISOs.
During the lifetime of the Participant, an Award will be exercisable only by the
Participant, and any elections with respect to an Award may be made only by the
Participant unless otherwise determined by the Committee and set forth in the
Award Agreement with respect to Awards that are not ISOs.

      12. RESTRICTIONS ON SHARES. At the discretion of the Committee, the
Company may reserve to itself and/or its assignee(s) in the Award Agreement a
right to repurchase a portion of or all of a Participant's Shares that are not
"vested" (as defined in the Award Agreement) following the Participant's
Termination at any time within ninety (90) days after the later of Participant's
Termination Date and the date Participant purchases Shares under this Plan, for
cash and/or cancellation of purchase money indebtedness, at the Participant's
Exercise Price or Purchase Price, as the case may be.

                                       8


      13. CERTIFICATES. All certificates for Shares or other securities
delivered under this Plan (whether in physical or electronic form, as
appropriate) will be subject to such stock transfer orders, legends and other
restrictions that the Committee deems necessary or advisable, including without
limitation restrictions under any applicable federal, state or foreign
securities law, or any rules, regulations and other requirements of the SEC or
any stock exchange or automated quotation system on which the Shares may be
listed.

      14. ESCROW; PLEDGE OF SHARES. To enforce any restrictions on a
Participant's Shares, the Committee may require the Participant to deposit all
certificates representing Shares, together with stock powers or other
instruments of transfer approved by the Committee, appropriately endorsed in
blank, with the Company or an agent designated by the Company to hold in
escrow until such restrictions have lapsed or terminated, and the Committee may
cause a legend or legends referencing such restrictions to be placed on the
certificates. Any Participant who is permitted to execute a promissory note as
partial or full consideration for the purchase of Shares under this Plan will be
required to pledge and deposit with the Company all or part of the Shares so
purchased as collateral to secure the payment of Participant's obligation to the
Company under the promissory note; provided, however, that the Committee may
require or accept other or additional forms of collateral to secure the payment
of such obligation and, in any event, the Company will have full recourse
against the Participant under the promissory note notwithstanding any pledge of
the Participant's Shares or other collateral. In connection with any pledge of
the Shares, Participant will be required to execute and deliver a written pledge
agreement in such form as the Committee will from time to time approve. The
Shares purchased with the promissory note may be released from the pledge on a
pro rata basis as the promissory note is paid.

      15. EXCHANGE AND BUYOUT OF AWARDS. The Committee may, at any time or from
time to time, authorize the Company, with the consent of the respective
Participants, to issue new Awards in exchange for the surrender and cancellation
of any or all outstanding Awards. The Committee may at any time buy from a
Participant an Award previously granted with payment in cash, Shares (including
Restricted Stock) or other consideration, based on such terms and conditions as
the Committee and the Participant may agree.

      16. SECURITIES LAW AND OTHER REGULATORY COMPLIANCE. An Award will not be
effective unless such Award is in compliance with all applicable state, federal
and foreign securities laws, rules and regulations of any governmental body, and
the requirements of any stock exchange or automated quotation system upon which
the Shares may that be listed or quoted, as they are in effect on the date of
grant of the Award and also on the date of exercise or other issuance.
Notwithstanding any other provision in this Plan, the Company will have no
obligation to issue or deliver certificates for Shares under this Plan prior to:
(a) obtaining any approvals from governmental agencies that the Company
determines are necessary or advisable; and/or (b) completion of any registration
or other qualification of such Shares under any state, federal or foreign law or
ruling of any governmental body that the Company determines to be necessary or
advisable. The Company will be under no obligation to register the Shares with
the SEC or to effect compliance with the registration, qualification or listing
requirements of any state, federal or foreign securities laws, stock exchange or
automated quotation system, and the Company will have no liability for any
inability or failure to do so.

      17. NO OBLIGATION TO EMPLOY. Nothing in this Plan or any Award granted
under this Plan will confer or be deemed to confer on any Participant any right
to continue in the employ of, or to continue any other relationship with, the
Company or any Parent or Subsidiary of the Company or limit in any way the right
of the Company or any Parent or Subsidiary of the Company to terminate
Participant's employment or other relationship at any time, with or without
cause.

      18. CORPORATE TRANSACTIONS.

            18.1 Assumption or Replacement of Awards by Successor. In the event
of

                  (a) a dissolution or liquidation of the Company;

                  (b) a merger or consolidation in which the Company is not the
surviving corporation (other than a merger or consolidation with a wholly-owned
subsidiary, a reincorporation of the Company in a different jurisdiction, or
other transaction in which there is no substantial change in the stockholders of
the Company or their relative stock holdings and the Awards granted under this
Plan are assumed, converted or replaced by the surviving corporation, which
assumption will be binding on all Participants);

                  (c) a merger in which the Company is the surviving corporation
but after which the stockholders of the Company immediately prior to such merger
(other than any stockholder that merges with the Company in such merger, or
which owns or controls another corporation that merges, with the Company in such
merger) cease to own their shares or other equity interest in the Company;

                  (d) the sale of all or substantially all of the assets of the
Company; or

                  (e) the acquisition, sale or transfer of more than 50% of the
outstanding shares of the Company by tender offer or similar transaction;

                  any or all outstanding Awards will automatically vest for one
additional year and may also be assumed, converted or replaced by the surviving
corporation (if any), which assumption, conversion or replacement will be
binding on all Participants. The Committee may, in its sole discretion, provide
for additional accelerated vesting of any or all Awards that are assumed,
converted or replaced by the surviving corporation. In lieu of assuming,
converting or replacing such Awards, the surviving corporation may substitute
equivalent Awards or provide substantially similar consideration to Participants
as was provided to stockholders (after taking into account the existing
provisions of the Awards and the one year additional vesting). The surviving
corporation may also issue, in place of outstanding Shares of the Company held
by the Participant, substantially similar shares or other property subject to
repurchase restrictions no less favorable to the Participant. In the event such
surviving corporation (if any) refuses to assume or substitute Awards, as
provided above, pursuant to a transaction described in this Subsection 18.1,
such Awards will automatically vest for one additional year and will expire on
such transaction at such time and on such conditions as the Committee will
determine, provided, however, that the Committee may, in its sole discretion,
provide for additional accelerated vesting of any or all Awards granted pursuant
to this Plan. If such accelerated options are not exercised prior to the
consummation of the corporate transaction, they shall terminate in accordance
with the provisions of this Plan.

            18.2 Other Treatment of Awards. Subject to any greater rights
granted to Participants under the foregoing provisions of this Section 18, in
the event of the occurrence of any transaction described in Section 18.1, any
outstanding Awards will be treated as provided in the applicable agreement or
plan of merger, consolidation, dissolution, liquidation, sale of assets or other
corporate transaction."

            18.3 Assumption of Awards by the Company. The Company, from time to
time, also may substitute or assume outstanding awards granted by another
company whether in connection with an aquisition of such other company or
otherwise, by either; (a) granting an Award under

                                       10


this Plan in substitution of such other company's award; or (b) assuming such
award as if it had been granted under this Plan if the terms of such assumed
award could be applied to an Award granted under this Plan. Such substitution or
assumption will be permissible if the holder of the substituted or assumed award
would have been eligible to be granted an Award under this Plan if the other
company had applied the rules of this Plan to such grant. In the event the
Company assumes an award granted by another company, the terms and conditions of
such award will remain unchanged (except that the exercise price and the number
and nature of Shares issuable upon exercise of any such option will be adjusted
appropriately pursuant to Section 424(a) of the Code). In the event the Company
elects to grant a new Option rather than assuming an existing option, such new
Option may be granted with a similarly adjusted Exercise Price.

      19. ADOPTION AND STOCKHOLDER APPROVAL. This Plan became effective on the
date on which the registration statement filed by the Company with the SEC under
the Securities Act registering the initial public offering of the Company's
Common Stock is declared effective by the SEC (the "Effective Date"). This Plan
was approved by the stockholders of the Company, consistent with applicable
laws, within twelve (12) months after the date this Plan was adopted by the
Board.

      20. TERM OF PLAN/GOVERNING LAW. Unless earlier terminated as provided
herein, this Plan will terminate ten (10) years from the date this Plan was
adopted by the Board. This Plan and all agreements thereunder shall be governed
by and construed in accordance with the laws of the State of Connecticut.

      21. AMENDMENT OR TERMINATION OF PLAN. The Board may at any time terminate
or amend this Plan in any respect, including without limitation amendment of any
form of Award Agreement or instrument to be executed pursuant to this Plan. In
addition, pursuant to Section 4.1(k), the Board has delegated to the Committee
the authority to make certain amendments to this Plan. Notwithstanding the
foregoing, neither the Board nor the Committee shall without the approval of the
stockholders of the Company amend this Plan in any manner that requires such
stockholder approval pursuant to the Code or the regulation promulgated
thereunder as such provisions apply to ISO plans, pursuant to the Exchange Act
or any rule promulgated thereunder or any rules or regulations promulgated by
the Stock exchange or automated quotation system on which the Company's Stock is
quoted. No amendment that is detrimental to a Participant may be made to any
outstanding Award without the consent of the Participant.

      22. NON-EXCLUSIVITY OF THE PLAN. Neither the adoption of this Plan by the
Board, the submission of this Plan to the stockholders of the Company for
approval, nor any provision of this Plan will be construed as creating any
limitations on the power of the Board to adopt such additional compensation
arrangements as it may deem desirable, including, without limitation, the
granting of stock options and bonuses otherwise than under this Plan, and such
arrangements may be either generally applicable or applicable only in specific
cases.
