            to be made available under the Plan, then the Committee shall, in
            such manner as it may deem equitable, adjust any or all of (i) the

            Plan to the contrary, grants to any one Participant of Awards which

            Shares in any calendar year.

            (i)   Exercise Price. The purchase price per Share purchasable under
                  an Option shall be determined by the Committee; provided,
                  however, that such purchase price shall not be less than the
                  Fair Market Value of a Share on the date of grant of such
                  Option.

            (ii)  Option Term. The term of each Option shall be fixed by the

                  of ten years from the date of

                                                                               6

                  its grant), and the method or methods by which, and the form
                  or forms (including, without limitation, cash, Shares, other
                  Awards or other property, or any combination thereof, having a
                  Fair Market Value on the exercise date equal to the relevant
                  exercise price) in which, payment of the exercise price with
                  respect thereto may be made; provided that no Shares may be
                  used by a Participant in payment of the exercise price of an
                  Option unless such Shares were acquired in the open market or
                  have been held by the Participant for at least six months.

            (iv)  Incentive Stock Options. The terms of any Incentive Stock
                  Option granted under the Plan shall comply in all respects
                  with the provisions of Section 422 of the Code, or any
                  successor provision thereto, and any regulations promulgated
                  thereunder. Without limiting the preceding sentence, the
                  aggregate Fair Market Value (determined at the time an option
                  is granted) of Shares with respect to which Incentive Stock
                  Options are exercisable for the first time by a Participant
                  during any calendar year (under the Plan and any other plan of
                  the Participant's employer corporation and its parent and
                  subsidiary corporations providing for Options) shall not
                  exceed such dollar limitation as shall be applicable to
                  Incentive Stock Options under Section 422 of the Code or a
                  successor provision.

                  receive any


<PAGE>

                                                                               7

                  dividend or other right or property), which restrictions may
                  lapse separately or in combination at such time or times, in
                  such installments or otherwise, as the Committee may deem
                  appropriate, provided that in order for a Participant to vest
                  in Awards of Restricted Stock or Restricted Stock Units where
                  vesting is based solely on continued service, the Participant
                  must remain in the employ of the Company or an Affiliate for a
                  period of not less than three years commencing on the date of
                  grant of the Award, subject to Section 9 hereof and subject to
                  relief for specified reasons as may be approved by the
                  Committee.

            (iii) Registration. Any Restricted Stock granted under the Plan may
                  be evidenced in such manner as the Committee may deem
                  appropriate, including, without limitation, book-entry
                  registration or issuance of a stock certificate or
                  certificates. In the event any stock certificate is issued in
                  respect of Shares of Restricted Stock granted under the Plan,
                  such certificate shall be registered in the name of the
                  Participant and when delivered to the Participant shall bear
                  an appropriate legend referring to the terms, conditions and
                  restrictions applicable to such Restricted Stock.

            (iv)  Forfeiture. Except as otherwise determined by the Committee,
                  upon termination of employment for any reason during the
                  applicable restriction period, all Shares of Restricted Stock
                  and all Restricted Stock Units still subject to restriction
                  shall be forfeited and reacquired by the Company; provided,
                  however, that the Committee may, in its sole discretion, waive
                  in whole or in part any or all remaining restrictions with
                  respect to Shares of Restricted Stock or Restricted Stock
                  Units. Unrestricted Shares, evidenced in such manner as the
                  Committee shall deem appropriate, shall be delivered to the
                  holder of Restricted Stock

            Awards to Participants. Subject to the terms of the Plan and any

            Performance Award, in whole or in part, upon the achievement of such
            performance goals during such performance periods as the Committee
            shall establish. Subject to the terms of the Plan and any applicable
            Award Agreement, the performance goals to be achieved during any
            performance period, the length of any performance period, the amount
            of any Performance Award granted, and the amount of any payment or
            transfer to be made pursuant to any Performance Award shall be
            determined by the Committee, provided that a performance period
            shall be at least one year, subject to Section 9 hereof.

                                                                               9

                  substitution of another Award. Awards so granted may be

                  Plan and of any applicable Award Agreement, payments to be
                  made by the Company or an Affiliate upon the grant, exercise,

                  property or any combination thereof, and may be made in a
                  single payment or transfer, in installments, or on a deferred
                  basis, in each case in accordance with rules and procedures
                  established by the Committee.

            (iv)  Dividend Equivalents or Interest. Subject to the terms of the
                  Plan and any applicable Award Agreement, a Participant,
                  including the recipient of a deferred Award, shall, if so

                  or on a deferred basis, interest or dividends or interest or
                  dividend equivalents, with respect to the Shares covered by
                  the Award. The Committee may provide that any such amounts
                  shall be deemed to have been reinvested in additional Shares
                  or otherwise reinvested. Notwithstanding the award of Dividend
                  Equivalents or dividend units, a Participant shall not be
                  entitled to receive a special or extraordinary dividend or
                  distribution unless the Committee shall have expressly
                  authorized such receipt.

                  Participant, and to receive any property distributable, upon
                  the death of the Participant. Each Award, and each right under
                  any Award, shall be exercisable, during the Participant's
                  lifetime, only by the Participant or, if permissible under
                  applicable law by the Participant's guardian or legal
                  representative unless it has been transferred to a member of
                  the holder's immediate family or to a trust for the benefit of
                  one or more of such immediate family members, in which case it
                  shall be exercisable only by such transferee. For the purposes
                  of this provision, a holder's "immediate family" shall mean
                  the holder's spouse, children and grandchildren. No Award
                  (other than Released Securities), and no right under any such
                  Award, may be pledged, attached or otherwise encumbered other
                  than in favor of the Company, and any purported pledge,
                  attachment, or encumbrance thereof other than in favor of the
                  Company shall be void and unenforceable against the Company or
                  any Affiliate.

            (vi)  Term of Awards. Except as otherwise expressly provided in the
                  Plan, the term of each Award shall be for such period as may
                  be determined by the Committee.

            (vii) Section 16 Rule Six-Month Limitations. To the extent required
                  in order to otherwise satisfy the requirements for exemption
                  under the Section 16 Rules only, any derivative or equity
                  security offered pursuant to the Plan may not be sold for at
                  least six months

                  after acquisition or grant (or such other period as may be
                  required by the Section 16 Rules), except in the case of
                  death. Terms used in the preceding sentence shall, for the
                  purposes of such sentence only, have the meanings, if any,
                  assigned or attributed to them under Section 16 Rules.

           (viii) No Rights to Awards. No Salaried Employee, Participant or
                  other Person shall have any claim to be granted an Award, and
                  there is no obligation for uniformity of treatment of Salaried
                  Employees, Participants or holders or beneficiaries of Awards
                  under the Plan. The terms and conditions of Awards need not be
                  the same with respect to each recipient. The prospective
                  recipient of any Award under the Plan shall not, with respect
                  to such Award, be deemed to have become a Participant, or to
                  have any rights with respect to such Award, until and unless
                  such recipient shall have executed an agreement or other
                  instrument accepting the Award and delivered a fully executed
                  copy thereof to the Company, and otherwise complied with the
                  then applicable terms and conditions.

           (ix)   Delegation. Notwithstanding any provision of the Plan to the
                  contrary, the Committee may delegate to one or more officers
                  or managers of the Company or any Affiliate, or a committee of
                  such officers or managers, the authority, subject to such
                  terms and limitations as the Committee shall determine, to
                  grant Awards to, or to cancel, modify, waive rights or
                  conditions with respect to, alter, discontinue, suspend, or
                  terminate Awards held by, Salaried Employees who are not
                  officers or directors of the Company for purposes of the
                  Section 16 Rules.

           (x)    Withholding. The Company or any Affiliate may withhold from
                  any Award granted or any payment due or transfer made under
                  any Award or under the Plan the amount (in cash, Shares, other
                  securities, other Awards, or

                                                                              12

                  other property) of withholding taxes due in respect of an
                  Award, its exercise or any payment under such Award or under
                  the Plan, and take such other action as may be necessary in
                  the opinion of the Company or Affiliate to satisfy all
                  obligations for the payment of such taxes.

           (xi)   Other Compensation Arrangements. Nothing contained in the Plan
                  shall prevent the Company or any Affiliate from adopting or
                  continuing in effect other or additional compensation
                  arrangements, and such arrangements may be either generally
                  applicable or applicable only in specific cases.

           (xii)  No Right to Employment. The grant of an Award shall not be
                  construed as giving a Participant the right to be retained in
                  the employ of the Company or any Affiliate. Nothing in the
                  Plan or any Award Agreement shall limit the right of the
                  Company or an Affiliate at any time to dismiss a Participant
                  from employment, free from any liability or any claim under
                  the Plan or the Award Agreement.

           (xiii) Governing Law. The validity, construction and effect of the
                  Plan and any rules and regulations relating to the Plan shall
                  be determined in accordance with the laws of the State of
                  Connecticut and applicable Federal law.

           (xiv)  Severability. If any provision of the Plan or any Award is
                  determined to be invalid, illegal or unenforceable in any
                  jurisdiction, or as to any Person or Award, or would
                  disqualify the Plan or any Award under any law deemed
                  applicable by the Committee, such provision shall be construed
                  or deemed amended to conform to applicable laws, or, if it
                  cannot be so construed or deemed amended without, in the
                  determination of the Committee, materially altering the intent
                  of the Plan or the Award, such

                  provision shall be stricken as to such jurisdiction, Person or
                  Award, and the remainder of the Plan and any such Award shall
                  remain in full force and effect.

          (xv)    No Trust or Fund Created. Neither the Plan nor any Award shall
                  create or be construed to create a trust or separate fund of
                  any kind or a fiduciary relationship between the Company or
                  any Affiliate and a Participant or any other Person. To the
                  extent that any Person acquires a right to receive payments
                  from the Company or any Affiliate pursuant to an Award, such
                  right shall be no greater than the right of any unsecured
                  general creditor of the Company or any Affiliate.

          (xvi)   No Fractional Shares. No fractional Shares shall be issued or
                  delivered pursuant to the Plan or any Award, and the Committee
                  shall determine whether cash, other securities or other
                  property shall be paid or transferred in lieu of any
                  fractional Shares, or whether such fractional Shares or any
                  rights thereto shall be canceled, terminated or otherwise
                  eliminated.

          (xvii)  Share Certificates. All certificates for Shares or other
                  securities delivered under the Plan pursuant to any Award or
                  the exercise thereof shall be subject to such stop transfer
                  orders and other restrictions as the Committee may deem
                  advisable under the Plan or the rules, regulations and other
                  requirements of the Securities and Exchange Commission, any
                  stock exchange upon which such Shares or other securities are
                  then listed, and any applicable Federal or state securities
                  laws, and the Committee may cause a legend or legends to be
                  put on any such certificates to make appropriate reference to
                  such restrictions.

          (xviii) Conflict with Plan. In the event of any inconsistency or
                  conflict between the terms of the Plan and an Award Agreement,
                  the terms of the Plan shall govern.

                  determined by the Committee prior to the start of the
                  performance period. "Earnings per Share"

                  that may be designated in Shares for any Participant in any
                  calendar year pursuant to Section 4(c). As used in and for all
                  purposes of the Plan (other than for purposes of Sections 4(a)

                  4(c) and 6(a)(i) of the Plan), the term "Option" includes an
                  option transferred to the Plan in connection with the
                  Distribution ("Transferred Option"), the term "Restricted
                  Stock Unit" includes a restricted stock unit transferred to
                  the Plan in connection with the Distribution ("Transferred

                  Option and a Transferred Stock Unit.

Section 7. Amendment and Termination

      (a)   Amendments to the Plan. The Board (or any authorized committee
            thereof) may amend, suspend, discontinue or terminate the Plan,
            including, without limitation, any amendment, suspension,
            discontinuation or termination that would impair the rights of any
            Participant, or any other holder or beneficiary of any Award
            theretofore granted, without the consent of any shareholder,
            Participant, other holder or beneficiary of an Award, or other
            Person; provided, however, that, notwithstanding any other provision
            of the Plan or any Award Agreement, without the approval of the
            shareholders of the Company, no such amendment, suspension,
            discontinuation or termination shall be made that would (i) amend
            the definition of "Participant" or the definition of "Salaried
            Employee" to include non-employee directors of the Company, (ii)
            except for adjustments provided in Section 4(b), increase the number
            of shares available for issuance under the Plan as specified in
            Section 4(a), or (iii) permit any Award encompassing rights to
            purchase Shares to be granted with per Share purchase or exercise
            prices of less than the Fair Market Value of a Share on the date of
            grant thereof; and

            provided further that no amendment, suspension, discontinuation or
            termination that would impair the rights of such Participant, holder
            or beneficiary shall be made with respect to Section 9 of the Plan
            after a Change in Control, as defined therein.

      (b)   Amendments to Awards. The Committee may waive any conditions or
            rights with respect to, or amend, alter, suspend, discontinue, or
            terminate, any unexercised Award theretofore granted, prospectively
            or retroactively, without the consent of any relevant Participant or
            holder or beneficiary of an Award, provided that no amendment,
            alteration, suspension, discontinuation or termination of an Award
            that would impair the rights of such Participant, holder or
            beneficiary shall be made after a Change in Control, as defined in
            Section 9; provided further that the Committee may not increase the
            payment of any Award granted any Participant.

            Company or any Affiliate shall assume outstanding employee awards or
            the right or obligation to make future such awards in connection
            with the acquisition of another business or another company, the
            Committee may make such adjustments, not inconsistent with the terms
            of the Plan, in the terms of Awards as it shall deem appropriate.

      (d)   Adjustments of Awards Upon the Occurrence of Certain Unusual or
            Nonrecurring Events. The Committee may make adjustments in the terms
            and conditions of Awards in recognition of unusual or nonrecurring
            events (including, without limitation, the events described in
            Section 4(b) hereof) affecting the Company, any Affiliate, or the
            financial statements of the Company or any Affiliate, or of changes
            in applicable laws, regulations, or accounting principles, whenever
            the Committee determines that statements of the Company or any
            Affiliate, or of changes in applicable laws, regulations, or
            accounting principles, whenever the Committee determines that such
            adjustments are appropriate in order to prevent dilution or
            enlargement of the benefits to be made available under the Plan.

Section 8. Additional Conditions to Enjoyment of Awards.

      (a)   The Committee may cancel any unexpired, unpaid or deferred Awards if
            at any time the Participant is not in compliance with all applicable
            provisions of the Award Agreement, the Plan and the following
            conditions:

            (i)   A Participant shall not render services for any organization
                  or engage, directly or indirectly, in any business which, in
                  the judgment of the Committee or, if delegated by the
                  Committee to the Chief Executive Officer, in the judgment of
                  such Officer, is or becomes competitive with the Company or
                  any Affiliate, or which is or becomes otherwise prejudicial to
                  or in conflict with the interests of the Company or any
                  Affiliate. Such judgment shall be based on the Participant's
                  positions and responsibilities while employed by the Company
                  or an Affiliate, the Participant's post-employment
                  responsibilities and position with the other organization or
                  business, the extent of past, current and potential
                  competition or conflict between the Company or an Affiliate
                  and the other organization or business, the effect on
                  customers, suppliers and competitors of the Participant's
                  assuming the post-employment position, the guidelines
                  established in the then current edition of the Company's
                  Standards of Ethical Business Practices, and such other
                  considerations as are deemed relevant given the applicable
                  facts and circumstances. The Participant shall be free,
                  however, to purchase as an investment or otherwise, stock or
                  other securities of such organization or business so long as
                  they are listed upon a recognized securities exchange or
                  traded over the counter, and such investment does not
                  represent a substantial investment to the Participant or a
                  greater than 1% equity interest in the organization or
                  business.

            (ii)  Participant shall not, without prior written authorization
                  from the Company, disclose to anyone outside the Company, or
                  use in other than the Company's business, any secret or
                  confidential information, knowledge or data, relating to the
                  business of the Company or an Affiliate in violation of his or
                  her agreement with the Company or the Affiliate.

            (iii) A Participant, pursuant to his or her agreement with the
                  Company or an Affiliate, shall disclose promptly and assign to
                  the Company or the Affiliate all right, title and interest in
                  any invention or idea, patentable or not, made or conceived by
                  the Participant during employment by the Company or the
                  Affiliate, relating in any manner to the actual or anticipated
                  business, research or development work of the Company or the
                  Affiliate and shall do anything reasonably necessary to enable
                  the Company or the Affiliate to secure a patent where
                  appropriate in the United States and in foreign countries.

      (b)   Notwithstanding any other provision of the Plan, the Committee in
            its sole discretion may cancel any Award at any time prior to the
            exercise thereof, if the employment of the Participant shall be
            terminated, other than by reason of death, unless the conditions in
            this Section 8 are met.

      (c)   Failure to comply with the conditions of this Section 8 prior to, or
            during the six months after, any exercise, payment or delivery
            pursuant to an Award shall cause the exercise, payment or delivery
            to be rescinded. The Company shall notify the Participant in writing
            of any such rescission within two years after such exercise payment
            or delivery and within 10 days after receiving such notice, the
            Participant shall pay to the Company the amount of any gain realized
            or payment received as a result of the exercise, payment or delivery
            rescinded. Such payment shall be made either in cash or by returning
            to the Company the number of Shares that the Participant received in
            connection with the rescinded exercise, payment or delivery.

      (d)   Upon exercise, payment or delivery pursuant to an Award, the
            Committee may require the Participant to certify on a form
            acceptable to the Committee, that he or she is in compliance with
            the terms and conditions of the Plan.

      (e)   Nothing herein shall be interpreted to limit the obligations of a
            Participant under his or her employee agreement or any other
            agreement with the Company.

      (a)   Except as the Board or the Committee may expressly provide otherwise
            prior to a Change in Control of the Company (as defined below), in

            (i)   all Options then outstanding shall become immediately and

                  the exercise in installments;

            (ii)  all restrictions and conditions of all Restricted Stock and
                  Restricted Stock Units then outstanding shall be deemed
                  satisfied as of the date of the Change in Control; and

            (iii) all Performance Awards shall become vested, deemed earned in
                  full and promptly paid to the Participants, cash units in cash
                  and phantom stock units in the Shares represented thereby or
                  such other securities, property or cash as may be deliverable
                  in respect of Shares as a result of a Change in Control,
                  without regard to payment schedules and notwithstanding that
                  the applicable performance cycle or retention cycle shall not
                  have been completed.
