                            ARTICLE 1. INTRODUCTION.

         1.1. QUALIFICATION AND PURPOSE. This document amends and restates the
provisions of the Boston Scientific Corporation 401(k) Retirement Savings Plan,
effective as of January 1, 2001 unless otherwise stated herein. Mergers and
account transfers of certain other plans into the Plan shall have such effective
dates as are provided in Schedule B. The original effective date of the Plan was
January 1, 1987. The Plan and its related Trust are intended to qualify as a
profit-sharing plan and trust under Code sections 401(a) and section 501(a), the
cash or deferred arrangement forming part of the Plan is intended to qualify
under Code section 401(k). The Plan is intended to constitute a plan described
in section 404(c) of ERISA. The provisions of the Plan and Trust shall be
construed and applied accordingly. The purpose of the Plan is to provide
benefits to Participants in a manner consistent and in compliance with such Code
sections and Title I of ERISA. Notwithstanding the general effective date
specified above, any provision of this restatement that is intended to comply
with changes in law made by the Uniform Services Employment and Reemployment
Rights Act of 1994, the Small Business Job Protection Act of 1996, the Taxpayer
Relief Act of 1997, the Uruguay Round Agreements Act, or Internal Revenue
Service regulations or other guidance thereunder, or Department of Labor
guidance shall be effective as of the effective dates specified for such changes
in the applicable statute, regulation, or guidance. In addition, this
restatement contains certain provisions of the Economic Growth and Tax Relief
Reconciliation Act of 2001 ("EGTRRA"). These provisions are intended as good
faith compliance with the requirements of EGTRRA and are to be construed in
accordance with EGTRRA and guidance issued thereunder. Except as otherwise
provided, the EGTRRA provisions shall be effective as of the first day of the
first Plan Year beginning after December 31, 2001. The EGTRRA provisions shall
supersede the provisions of the Plan to the extent those provisions are
inconsistent with the EGTRRA provisions.

         1.2. RIGHTS UNDER PLANS. The rights of Participants in this Plan or any
other plan which has been merged into this Plan, who ceased to be employed by
the applicable employer prior to January 1, 2001 or, if later, the applicable
merger date provided in Schedule B and have not thereafter been reemployed by
the Plan Sponsor or an Affiliated Employer, and the rights of their
beneficiaries, shall be determined in accordance with the terms of the
applicable plan at the time they ceased to be employed.

         1.3. DEFINED TERMS. All capitalized terms used in the following
provisions of the Plan have the meanings given them under Article 14.

<PAGE>

                           ARTICLE 2. PARTICIPATION.

         2.1. DATE OF PARTICIPATION.

                  (a) Any individual who was a Participant on December 31, 2000
         and is an Eligible Employee on January 1, 2001 will, subject to Section
         2.2, continue to be a Participant.

                  (b) Any other individual will become a Participant on the
         Entry Date coinciding with or next following the latest of

                           (1) January 1, 2001;

                           (2) the date on which he or she becomes an Eligible
                  Employee;

                           (3) the date on which he or she attains age 21; and

                           (4) the 30th day after the date he or she completes
                  an Hour of Service;

         provided that (i) he or she is an Eligible Employee on such Entry Date
         and (ii) he or she has in effect on such Entry Date a compensation
         reduction authorization described in Section 3.2 which was submitted in
         the manner prescribed by the Committee. Unless otherwise provided by
         the Committee, an Employee who has satisfied the requirements of (1),
         (2), (3) and (4) above, but who has failed to satisfy the requirements
         of (i) or (ii) above, will become a Participant on the first Entry Date
         coinciding with or next following the date on which the requirements of
         both (i) and (ii) are satisfied.

                  (c) Unless otherwise provided in Schedule B, in the event the
         Plan Sponsor acquires a business of another employer, through an
         acquisition of either assets or stock, an Employee who was employed by
         such other employer immediately prior to such acquisition shall have
         his or her prior service with such other employer taken into account,
         as if it were service with an Affiliated Employer, for purposes of
         (b)(4) above and Section 14.14(b).

                  (d) An Employee who, immediately before becoming an Eligible
         Employee, has a contribution agreement in effect with an Affiliated
         Employer under a separate plan described in section 401(k) of the Code
         shall become a Participant on the payroll date coinciding with or next
         following the date he or she becomes an Eligible Employee, provided
         that he or she has a compensation reduction authorization in effect on
         such payroll date.

         2.2. DURATION OF PARTICIPATION. An individual who has become a
Participant under the Plan will remain a Participant for as long as an Account
is maintained under the Plan for his or her benefit, or until his or her death,
if earlier. Notwithstanding the

                                      - 2 -

<PAGE>

preceding sentence and unless otherwise expressly provided for under the Plan,
no contributions shall be made with respect to a Participant who is not an
Eligible Employee. In the event a Participant remains an Employee but ceases to
be an Eligible Employee and becomes ineligible for contributions, such Employee
will again become eligible for contributions immediately upon returning to the
class of Eligible Employees. In the event an Employee who is not an Eligible
Employee becomes an Eligible Employee, such Employee will become a Participant
on the first Entry Date on or after becoming an Eligible Employee, if he or she
has satisfied the requirements of Section 2.1. A Participant or former
Participant who is reemployed as an Eligible Employee shall again become
eligible for contributions on the first Entry Date on or after reemployment.

                           ARTICLE 3. CONTRIBUTIONS.

         3.1. ELECTIVE CONTRIBUTIONS. On behalf of each Participant for whom
there is in effect, for any pay period, a compensation reduction authorization
described in Section 3.2 and who is receiving Compensation from a Participating
Employer during such pay period, such Participating Employer will contribute to
the Trust, as an Elective Contribution, an amount equal to the amount by which
such Compensation was reduced pursuant to the compensation reduction
authorization. Elective Contributions for any pay period in a Plan Year may not
be less than 1 percent nor exceed 15 percent of the Participant's Compensation
for such pay period.

         3.2. FORM AND MANNER OF ELECTIONS. A "compensation reduction
authorization" is an authorization from an Eligible Employee to a Participating
Employer which satisfies the requirements of this Section 3.2. Each compensation
reduction authorization shall be in a form prescribed or approved by the
Committee, and may be entered into as of any Entry Date upon such prior notice
as the Committee may prescribe. A compensation reduction authorization may be
changed by the Participant, with such prior notice as the Committee may
prescribe, as of the first day of any payroll period. A compensation reduction
authorization shall be effective with respect to Compensation payable on and
after the applicable Entry Date. A compensation reduction authorization may be
revoked by the Participant at any time, upon such prior notice as the Committee
may prescribe. A Participant who revokes a compensation reduction authorization
may enter into a new authorization only as of a subsequent Entry Date.

         3.3. MATCHING CONTRIBUTIONS.

                  (a) On a bi-weekly basis, each Participating Employer will
         make a Matching Contribution to the Trust for the benefit of each
         Participant on whose behalf it made Elective Contributions for the
         period. The amount of Matching Contributions made by a Participating
         Employer for the period shall be equal to (i) 100% of the Elective
         Contributions made on behalf of the Participant for the period which do
         not exceed 2% of the Participant's Compensation for such period, plus
         (ii) 50% of the Elective Contributions made on behalf of the
         Participant for the period which exceed 2% but do not exceed 4% of the
         Participant's Compensation for such period.

                  (b) If (i) a Participant is an Eligible Employee on the last
         day of the Plan Year, and (ii) the aggregate Matching Contributions
         made by his or her Participating Employer under paragraph (a) above to
         the Trust for the benefit of such Participant with respect to such Plan
         Year are less than the lesser of (1) 100% of the Participant's Elective
         Contributions for such Plan Year which do not exceed 2% of the
         Participant's Compensation for such Year plus 50% of the Participant's
         Elective Contributions for such Plan Year which exceed 2% but do not
         exceed 4% of the Participant's Compensation for such Year; or (2) 3% of
         such Participant's Compensation in such Plan Year, then the
         Participating Employer shall make a further contribution to the Trust,
         for the benefit of such Participant, to be credited

                                      - 4 -

<PAGE>

         to his or her Matching Contribution Account, such that the aggregate
         Matching Contributions made by the Participating Employer for the
         benefit of such Participant for the Plan Year under this Section shall
         equal the lesser of the amounts set forth in clauses (1) and (2) above.

         3.4. DISCRETIONARY CONTRIBUTIONS. For each Plan Year, the Participating
Employers shall contribute to the Plan such other amounts, if any, as the Board
of Directors, in its sole discretion, may determine. Any such Discretionary
Contribution for a Plan Year shall be made in cash or, if the Board of Directors
so directs, in Company Stock, and shall be allocated among and credited to the
Accounts of each Participant who:

                  (a) is an Eligible Employee on the last day of the Plan Year;
         or

                  (b) has ceased to be an Eligible Employee during the Plan Year
         by reason of death or severance from employment after attaining age 62
         or on account of Disability,

in proportion to their relative amounts of Compensation for such Plan Year.

         3.5. QUALIFIED NONELECTIVE CONTRIBUTIONS. To the extent necessary to
satisfy the Code Section 401(k)(3) limits with respect to Elective Contributions
or the Code Section 401(m) limits with respect to Matching Contributions, the
Plan Sponsor, in its discretion, may determine whether a Qualified Nonelective
Contribution shall be made to the Trust for a Plan Year and, if so, the amount
to be contributed by such Participating Employer. If the Plan Sponsor determines
that a Qualified Nonelective Contribution shall be made, each Participating
Employer shall contribute its designated portion. Qualified Nonelective
Contributions shall be fully vested and subject to the same distribution rules
as Elective Contributions as of the time such Qualified Nonelective
Contributions are made to the Plan.

         3.6. ROLLOVER CONTRIBUTIONS. An Eligible Employee (whether or not a
Participant) may make a Rollover Contribution to the Plan upon demonstration to
the Committee that the contribution is eligible for transfer to the Plan
pursuant to the rollover provisions of the Code.

         3.7. EMPLOYEE CONTRIBUTIONS. A Participant may elect to make after-tax
Employee Contributions under the Plan in the form and manner prescribed or
approved by the Committee. Employee Contributions for any pay period in a Plan
Year may not be less than 1 percent nor exceed 10 percent of the Participant's
Compensation for such period.

         3.8. OTHER EMPLOYER CONTRIBUTIONS. The Participating Employers shall
contribute to the Plan such other amounts as the Board of Directors determines
on behalf of certain eligible Participants as set forth on Schedule C. Such
contributions shall be made in cash and shall be allocated to an Employer
Contribution Account of each eligible Participant as set forth on Schedule C.

         3.9. CREDITING OF CONTRIBUTIONS. Each type of contribution for a Plan
Year shall be allocated among and credited to the respective Accounts of
Participants eligible to share in the contributions as of the Valuation Date
next following the date the contributions are received by the Trustee.

         3.10. TIME FOR MAKING CONTRIBUTIONS. Elective Contributions will be
paid in cash to the Trust as soon as such contributions can reasonably be
segregated from the general assets of the Participating Employer, but in any
event no later than the time set forth in Department of Labor Regulations
section 2510.3-102.

         3.11. CERTAIN LIMITS APPLY. All contributions to the Plan are subject
to the applicable limits set forth under Code sections 401(k), 402(g), 401(m),
404, and 415, as further described elsewhere in the Plan. In addition, certain
minimum allocations may be required under Code section 416, as also further
described elsewhere in the Plan.

         3.12. RETURN OF CONTRIBUTIONS. If any contribution by a Participating
Employer to the Trust is (a) made by reason of a mistake of fact, or (b)
believed by the Participating Employer in good faith to be deductible under Code
section 404, but the deduction is disallowed, the Trustee shall, upon request by
the Participating Employer, return to the Participating Employer the excess of
the amount contributed over the amount, if any, that would have been contributed
had there not occurred a mistake of fact or a mistake in determining the
deduction. Such excess shall be reduced by the losses of the Trust attributable
thereto, if and to the extent such losses exceed the gains and income
attributable thereto. In no event shall the return of a contribution hereunder
cause any Participant's Accounts to be reduced to less than they would have been
had the mistaken or nondeductible amount not been contributed. No return of a
contribution hereunder shall be made more than one year after the mistaken
payment of the contribution, or disallowance of the deduction, as the case may
be.

         3.13. ESTABLISHMENT OF TRUST. The Plan Sponsor will establish a Trust
to accept and hold contributions made under the Plan. The Trust shall be
governed by an agreement between the Plan Sponsor and the Trustee the terms of
which shall be consistent with the Plan provisions and intended qualification
under Code sections 401(a) and 501(a).

                        ARTICLE 4. PARTICIPANT ACCOUNTS.

         4.1. ACCOUNTS. The Committee will establish and maintain (or cause the
Trustee to establish and maintain) for each Participant, such Accounts as are
necessary to carry out the purposes of this Plan.

         4.2. ADJUSTMENT OF ACCOUNTS. As of each Valuation Date, each Account
will be adjusted to reflect the fair market value of the assets allocated to the
Account. In so doing,

                  (a) each Account balance will be increased by the amount of
         contributions, income and gain allocable to such Account since the
         prior Valuation Date; and

                  (b) each Account balance will be decreased by the amount of
         distributions from the Account and expenses and losses allocable to the
         Account since the prior Valuation Date.

Income, expense, gain or loss which is generated by a particular investment
within the Trust shall be allocated among the Accounts invested in that
investment in proportion to the balances of such Accounts as of the immediately
preceding Valuation Date. Any expenses relating to a specific Account or
Accounts, including without limitation commissions or sales charges with respect
to an investment in which the Account participates, but excluding costs relating
to the processing of Qualified Domestic Relations Orders, may be charged solely
to the particular Account or Accounts.

         4.3. INVESTMENT OF ACCOUNTS.

                  (a) A Participant's Accounts shall be invested by the Trustee
         as the Participant directs from among such investment options as the
         Plan Sponsor may make available from time to time in accordance with
         the investment policy established by the Committee. The Committee shall
         prescribe the manner in which such directions may be made or changed,
         the dates as of which they shall be effective, and the allocation of
         Accounts with respect to which no directions are submitted. Any other
         assets of the Trust not specified above in this Section shall be
         invested by the Trustee in the sole discretion of the Trustee and in
         accordance with its fiduciary duties under ERISA; provided, that if an
         investment manager or other named fiduciary has been appointed with
         respect to all or a portion of such assets, the Trustee shall invest
         such portion as the investment manager or other named fiduciary
         directs.

                  (b) The Committee is specifically authorized to establish a
         Company Stock investment option. To the extent such Company Stock has
         voting rights, or in the event of any tender or exchange offer by any
         person for such Company Stock, Participants invested in such Company
         Stock fund may direct the Trustee as to the voting and tender of such
         Company Stock in accordance with procedures established by the
         Committee. The Committee may also provide for the temporary suspension
         of the right of Participants subject to Section 16 of the Securities
         Exchange Act of 1934 to invest further amounts in the Company Stock
         fund following any withdrawal from the portion of such Participants'
         Accounts theretofore invested in such Company Stock fund. The Committee
         may also establish from time to time a maximum percentage of any
         Participant's Accounts which may be invested in the Company Stock fund.

                  (c) In connection with the acquisition of Schneider (USA) Inc.
         and Corvita Corporation, the Company established an investment fund to
         hold shares of Pfizer Inc. common stock transferred from the Pfizer
         Savings and Investment Plan. No contributions under this Plan may be
         invested in the Pfizer stock fund, and dividends and interest payable
         on the assets of the Pfizer stock fund allocated to the Accounts of a
         Participant will be invested according to such Participant's current
         investment election for contributions under the Plan. A Participant may
         direct that amounts held in the Pfizer stock fund on his or her behalf
         be transferred to one or more other investment funds made available by
         the Committee from time to time, and any amounts so transferred shall
         not be reallocated to the Pfizer stock fund.

         4.4. APPOINTMENT OF INVESTMENT MANAGER OR NAMED FIDUCIARY. The Plan
Sponsor may appoint in writing one or more investment managers or other "named
fiduciaries" (within the meaning of ERISA section 402(a)(2)) to manage the
investment of all or designated portions of the assets held in the Trust. The
appointment shall be effective upon acknowledgment in writing by the investment
manager or other named fiduciary that it is a fiduciary with respect to the
Plan. An investment manager must be (a) registered as an investment adviser
under the Investment Advisers Act of 1940, (b) a bank as defined in that Act, or
(c) an insurance company qualified under the laws of more than one state to
manage, acquire or dispose of any assets of the Plan.

         4.5. SECTION 404(c) COMPLIANCE. The Plan is intended to be an "ERISA
section 404(c) plan" as described in section 404(c) of ERISA and title 29 of the
Code of Federal Regulations section 2550.404c-1, and shall be administered and
interpreted in a manner consistent with that intent. The investment direction
requirements of Department of Labor regulation section 2550.404c-1(b)(2)(i)(B)
(1)(iv) and (b)(2)(i)(A) and the requirements relating to the investment
alternatives under the Plan are intended to be satisfied by Section 4.3 above,
in each case taking into account related communications to Participants and
beneficiaries under the summary plan description for the Plan and other
communications. For purposes of ERISA section 404(c), the "identified plan
fiduciary" obligated to comply with Participant and Beneficiary investment
instructions (except as provided in such section and regulations thereunder),
the identified plan fiduciary obligated to provide Participants and
Beneficiaries with the materials set forth in Department of Labor regulations
section 2550.404c-1(b)(2)(i)(B) and the identified plan fiduciary obligated to
comply with the confidentiality requirements and procedures under Department of
Labor regulations section 2550.404c-1(d)(2)(ii)(E)(4)(viii) relating to employer
securities shall be the Committee. The Committee may decline to implement
Participant and Beneficiary investment instructions which would result in a
prohibited transaction described in ERISA section 406 or section 4975 of the
Code or which would generate income that would be taxable to the Plan.

         4.6. TRANSFERS FROM OTHER PLANS.

                  (a) Unless otherwise provided herein, in the event that
         another plan is merged into the Plan, or accounts are otherwise
         transferred to the Plan from another plan, the assets transferred to
         the Plan shall be allocated as follows:

                           (1) Assets attributable to an individual's elective
                  contributions and qualified nonelective contributions (if any)
                  shall be allocated to an Elective Contribution Account for his
                  or her benefit under the Plan;

                           (2) Assets attributable to matching employer
                  contributions (if any), shall be allocated to a Matching
                  Contribution Account for his or her benefit under the Plan;

                           (3) Assets attributable to other employer
                  contributions (if any), shall be allocated to a Discretionary
                  Contribution Account for his or her benefit under the Plan;
                  and

                           (4) Assets attributable to an individual's after-tax
                  contributions (if any) shall be allocated to an after-tax
                  contribution account for his or her benefit under the Plan.

                  The assets transferred may be separately accounted for in
         sub-accounts under the Plan as determined to be necessary by the
         Committee in order to administer the provisions of Articles 5, 6, 7 and
         8. Unless otherwise provided in Schedule B or in an acquisition
         agreement between a Participating Employer and the employer maintaining
         such transferor plan, all assets transferred under this Section 4.6
         shall be invested in accordance with investment directions by the
         Participant under Section 4.3 above or, absent such directions, in a
         fund designated by the Committee.

                  (b) Any individual for whom accounts have been transferred
         under this Section 4.6 and who has not become a Participant under
         Section 2.1, or pursuant to such other special eligibility rules
         provided in Schedule B, shall be treated as a Participant for purposes
         of Articles 4, 5, 8, 9, 10 and 13 and, so long as he or she is an
         Employee, Articles 6 and 7. Such an individual shall become a
         Participant for all purposes of the Plan to the extent such individual
         satisfies the requirements of Section 2.1 or any other special
         eligibility rules provided in Schedule B which apply to such
         individual.

                        ARTICLE 5. VESTING OF ACCOUNTS.

         5.1. IMMEDIATE VESTING OF CERTAIN ACCOUNTS. A Participant shall at all
times have a vested interest in 100% of the following accounts, as applicable:
Elective Contribution Account, Employee Contribution Account, QNEC Account,
Matching Contribution Account, his or her Rollover Account, and other accounts
that the Committee may establish, unless explicitly provided otherwise herein.

         5.2. DEFERRED VESTING OF DISCRETIONARY CONTRIBUTION ACCOUNTS.

                  (a) A Participant who on December 31, 1992 had at least three
         Years of Service for purposes of calculating vesting, shall have a
         vested interest in 100% of his or her Discretionary Contribution
         Account, if any.

                  (b) A Participant not described in (a) above, shall have a
         vested interest in a percentage of his or her Discretionary
         Contribution Account, if any, determined in accordance with the
         following schedule and based on his or her Years of Service for
         Vesting:

<TABLE>
<CAPTION>
 Years of Service                    Applicable
   for Vesting                Nonforfeitable Percentage
 ----------------             -------------------------
<S>                           <C>
less than 1                               0%

2 but less than 3                        40%
3 but less than 4                        60%
4 but less than 5                        80%
5 or more                               100%
</TABLE>

         5.3. SPECIAL VESTING RULES. Notwithstanding any provision of the Plan
to the contrary, a Participant will have a vested interest in 100% of the
Accounts maintained for his or her benefit upon the happening of any one of the
following events:

                  (a) the Participant's attainment of age 62 while an Employee;

                  (b) the Participant's severance from employment on account of
         Disability;

                  (c) the Participant's death while an Employee;

                  (d) the termination of the Plan or the complete discontinuance
         of Contributions under the Plan; or

                  (e) the partial termination of the Plan with respect to the
         Participant.

         5.4. CHANGES IN VESTING SCHEDULE. If the Plan's vesting schedule is
amended, or the Plan is amended in any way that directly or indirectly affects
the computation of a Participant's vested percentage (or if the Plan changes to
or from a top-heavy vesting schedule), each Participant who

                                     - 10 -

<PAGE>

has completed 3 years of Vesting Service may elect, within the period described
below, to have his or her vested percentage determined without regard to such
amendment or change. The period referred to in the preceding sentence will begin
on the date the amendment of the vesting schedule is adopted and will end 60
days after the latest of the following dates:

                  (a) the date on which such amendment is adopted;

                  (b) the date on which such amendment becomes effective; and

                  (c) the date on which the Participant is issued written notice
         of such amendment by the Committee.

         5.5. FORFEITURES.

                  (a) In general. Any portion of a Participant's Account in
         which he or she is not vested upon severance from employment for any
         reason will be forfeited as of the earlier of

                           (1) the expiration of 5 consecutive Plan Years during
                  each of which the Participant does not complete 501 Hours of
                  Service, or

                           (2) the distribution of the vested portion of the
                  Account if such distribution is made as a result of the
                  Participant's severance from employment.

Any Participant who separates from the service of the Affiliated Employers prior
to earning a vested interest in any of his or her Accounts shall be deemed to
have received a complete distribution of his or her vested interest on the day
he or she separates from service.

                  (b) Certain Restorations. Notwithstanding the preceding
         paragraph, if a Participant forfeits any portion of an Account as a
         result of the complete distribution of the vested portion of the
         Account but thereafter returns to the employ of an Affiliated Employer,
         the amount forfeited will be recredited to the Participant's Account if
         he or she repays to the Plan the entire amount distributed, without
         interest, prior to the earlier of (i) the close of the fifth
         consecutive Plan Year in each of which the Participant does not
         complete at least 501 Hours of Service or (ii) the fifth anniversary of
         the date on which the Participant is reemployed. In the case of a
         Participant who had earlier separated from service prior to earning a
         vested interest in any of his or her Accounts and was deemed to have
         received a distribution of such vested interest, the amount forfeited
         will be restored upon the Participant's reemployment prior to the close
         of the fifth consecutive Plan Year in each of which the Participant
         does not complete at least 501 Hours of Service. A Participant's vested
         percentage in the amount recredited under this paragraph will
         thereafter be determined under the terms of the Plan as if no
         forfeiture had occurred. The money required to effect the restoration
         of a Participant's Account shall come from other Accounts forfeited
         during the Plan Year of restoration, and to the extent such funds are
         inadequate, from a special contribution by the Participant's
         Participating Employer.

                  (c) If a Participant forfeits any part of his or her Accounts
         under paragraph (a) above, the amount of the forfeiture will be
         applied, first, toward any restoration of any

                                     - 11 -

<PAGE>

         amount previously forfeited as required under paragraph (a) above, and,
         then, toward the Matching Contributions required to be made to the Plan
         under Section 3.3.

         5.6. VESTING OF ACCOUNTS TRANSFERRED FROM OTHER PLANS. In the event
that another plan is merged into the Plan, or accounts are otherwise transferred
to the Plan from another plan, the portion of each Account under this Plan that
is attributable to a vested and nonforfeitable account, or portion of an
account, under the transferor plan shall remain vested and nonforfeitable under
this Plan. The remaining portion of each Account under this Plan that is
attributable to a transferor plan account shall vest in accordance with Section
5.2, unless otherwise provided in Schedule B.

           ARTICLE 6. WITHDRAWALS PRIOR TO SEVERANCE FROM EMPLOYMENT.

         6.1. HARDSHIP WITHDRAWALS.

                  (a) Immediate and heavy financial need. A Participant may make
         a withdrawal from his or her Elective Contribution Account in the event
         of an immediate and heavy financial need arising from

                           (i) expenses for medical care described in Code
                  section 213(d) previously incurred by the Participant, his or
                  her spouse or any of his or her dependents (as defined in Code
                  section 152) or amounts necessary for these persons to obtain
                  such medical care;

                           (ii) costs directly related to the purchase of a
                  principal residence of the Participant (excluding mortgage
                  payments);

                           (iii) the payment of tuition, room and board expenses
                  and related educational fees for the next 12 months of
                  post-secondary education for the Participant, his or her
                  spouse, children or dependents (as defined in Code section
                  152);

                           (iv) payments necessary to prevent the eviction of
                  the Participant from his or her principal residence or
                  foreclosure on the mortgage on that principal residence; or

                           (v) any other need identified by the Commissioner of
                  Revenue as a "financial hardship" for purposes of section
                  401(k) plans through the publication of revenue rulings,
                  notices and other guidance of general applicability.

         The Committee's determination of whether there is an immediate and
         heavy financial need as defined above shall be made solely on the basis
         of written evidence furnished by the Participant. Such evidence must
         also indicate the amount of such need.

                  (b) Distribution of amount necessary to meet need. As soon as
         practicable after the Committee's determination that an immediate and
         heavy financial need exists with respect to the Participant, that the
         Participant has obtained all other distributions (other than hardship
         distributions) and all nontaxable loans currently available under the
         Plan and all other plans maintained by the Affiliated Employers, and
         that no other resources are reasonably available to the Participant to
         satisfy the need, the Committee will direct the Trustee to pay to the
         Participant the amount necessary to meet the need created by the
         hardship (but not in excess of the value of the Participant's Elective
         Contribution Account, determined as of the Valuation Date that
         authorized distribution directions are received by the Trustee). The
         amount necessary to meet the need may include any amounts necessary to
         pay any federal, state, or local income taxes or penalties reasonably
         anticipated to result from the distribution. Distribution will be made
         solely from the Participant's Elective Contribution Account, and shall
         not include any portion of the Account that is attributable to income
         earned after December 31, 1988.

         6.2. WITHDRAWALS AFTER AGE 59 1/2. A Participant who is an Employee and
has attained age 59 1/2 may make a withdrawal from any one or more of his or her
Accounts for any reason, upon such prior notice as the Committee may prescribe.
Any such withdrawal shall be in the amount specified by the Participant, up to

practicable after such Valuation Date.

         6.4. WITHDRAWAL ON ACCOUNT OF DISABILITY. A Participant who is an

Committee may prescribe. Any such withdrawal shall be in the amount specified by
the Participant in accordance with procedures prescribed by the Committee, up to
the value of the Participant's Employee Contribution Account, determined as of
the Valuation Date that authorized distribution directions are received by the
Trustee. Payment to the Participant shall be made as soon as practicable after
such Valuation Date.

         6.6. RESTRICTIONS ON CERTAIN DISTRIBUTIONS. In the case of a
Participant whose Accounts are valued in excess of $5,000 and who has not yet
attained the Normal Retirement Age, no distribution may be made to the
Participant under this Article unless

                  (a) between the 30th and 90th day prior to the date
         distribution is to be made, the Committee notifies the Participant in
         writing that he or she may defer distribution until the Normal
         Retirement Age and provides the Participant with a written description
         of the material features and (if applicable) the relative values of the
         forms of distribution available under the Plan; and

                  (b) the Participant consents to the distribution in writing
         after the information described above has been provided to him or her.

Notwithstanding the foregoing, such distribution may commence less than 30 days
after the required notification described above is given, provided that (i) the
Committee clearly informs the Participant that the Participant has a right to a
period of at least 30 days after receiving the notice to consider whether or not
to elect a distribution; and (ii) the Participant, after receiving the notice,
elects a distribution.

                                     - 14 -

<PAGE>

For purposes of this Section, a Participant's Accounts will be considered to be
valued in excess of $5,000 if the value of his or her Accounts exceeds such
amount at the time of the distribution in question. For the avoidance of doubt,
nothing in this Section confers a substantive distribution right to any
Participant; a Participant must be eligible to receive a distribution pursuant
to the other provisions of this Article 6 in order for this Section to apply.

         6.7. LIMITATION OF WITHDRAWABLE AMOUNT. In the event that there is
allocated to a Participant's Account a promissory note with respect to a loan
made from the Plan, the maximum amount of cash that may be withdrawn from the
Account prior to the Participant's severance from employment shall be determined
without regard to the value of such note.

         6.8. REQUIRED DISTRIBUTIONS AFTER REQUIRED BEGINNING DATE. In the case
of a Participant who remains an Employee on or after his or her Required
Beginning Date, such Participant's Accounts will be distributed, beginning on
his or her Required Beginning Date, in accordance with the applicable
requirements of Code section 401(a)(9) and the Regulations promulgated
thereunder.

         6.9. DISTRIBUTIONS REQUIRED BY A QUALIFIED DOMESTIC RELATIONS ORDER. To
the extent required by a Qualified Domestic Relations Order, the Committee shall
make distributions from a Participant's Accounts to alternate payees named in
such order in a manner consistent with the distribution options otherwise
available under the Plan, regardless of whether the Participant is otherwise
entitled to a distribution at such time under the Plan.

         6.10. WITHDRAWALS BY CERTAIN FORMER PARTICIPANTS IN OTHER PLANS.

                  (a) In addition to the rights to take withdrawals prior to
         severance from employment as described above, in the case of a
         Participant for whom amounts have been transferred under Section 4.6,
         the Participant shall be entitled to take withdrawals hereunder in the
         circumstances in which withdrawals prior to severance from employment
         would have been permitted under the transferor plan, as set forth in
         Schedule B.

                  (b) In the case of a married Participant for whom amounts have
         been transferred under Section 4.6 from another plan and who has at any
         time elected an annuity form of payment under Section 8.7, no
         withdrawal may be made under this article unless (i) his or her spouse
         consents in writing to such withdrawal, such consent acknowledges the
         effect of the withdrawal and is witnessed by a Plan representative or a
         notary public, and such consent specifies the form of the withdrawal
         (i.e., a lump sum cash payment), or (ii) it is established to the
         satisfaction of the Committee that the foregoing consent may not be
         obtained because the spouse cannot be located, or because of such other
         circumstances as the Secretary of the Treasury may prescribe.

                       ARTICLE 7. LOANS TO PARTICIPANTS.

         7.1. IN GENERAL. Upon the written request of a Participant on a form
acceptable to the Committee, and subject to the conditions of this Article, the
Committee shall direct the Trustee to make a loan from the Trust to the
Participant. Notwithstanding the foregoing, a Participant who is an
owner-employee or member of the family (as defined in Code section 267(e)(4) of
an owner-employee is not eligible to receive a loan under this Article 7. An
"owner-employee" shall mean an owner employee as defined in Code section
401(c)(3), and shall include an employee or officer of an electing small
business (Subchapter S) corporation which is an Affiliated Employer who owns (or
is considered as owning within the meaning of Code section 318(a)(1)), on any
day during the taxable year of such corporation, more than 5% of the outstanding
stock of such corporation. For purposes of this Article, "Participant" includes
any Participant who is an Employee of a Participating Employer, and any other
Participant (or Beneficiary of a deceased Participant) who is a "party in
interest" within the meaning of ERISA section 3(14).

         7.2. RULES AND PROCEDURES. The Committee shall promulgate such rules
and procedures, not inconsistent with the express provisions of this Article, as
it deems necessary to carry out the purposes of this Article including, but not
limited to, rules for charging loan fees directly to a Participant's Accounts.
All such rules and procedures shall be deemed a part of the Plan for purposes of
the Department of Labor regulation section 2550.408b-1(d). Loans shall not be
made available to Participants who are Highly Compensated Employees in an amount
(determined under Department of Labor regulation section 2550.408b-1(b)) greater
than the amount made available to other Participants.

         7.3. MAXIMUM AMOUNT OF LOAN. The following limitations shall apply in
determining the amount of any loan to a Participant hereunder:

                  (a) The amount of the loan, together with any other
         outstanding indebtedness of the Participant under the Plan or any other
         qualified retirement plans of the Affiliated Employers, shall not
         exceed $50,000 reduced by the excess of (i) the highest outstanding
         loan balance of the Participant from such plans during the one-year
         period ending on the day prior to the date on which the loan is made,
         over (ii) the Participant's outstanding loan balance from such plans
         immediately prior to the loan.

                  (b) The amount of the loan shall not exceed 50% of the
         Participant's vested interest in his or her Accounts, determined as of
         the Valuation Date immediately preceding the date of the loan.

         7.4. MINIMUM AMOUNT OF LOANS; LIMIT ON NUMBER OF LOANS. The amount of
any single loan under this Plan shall not be less than $1,000. No more than two
loans may be outstanding to a Participant at any one time.

         7.5. NOTE; SECURITY; INTEREST. Each loan shall be evidenced by a note
signed by the Participant and shall be secured by the Participant's vested
interest in his or her Accounts, including in such security the note evidencing
the loan. The loan shall bear interest at a reasonable annual percentage
interest rate to be determined by the Committee. In determining the interest
rate, the

                                     - 16 -

<PAGE>

Committee shall take into consideration interest rates currently being charged
by persons in the business of lending money with respect to loans made in
similar circumstances.

         7.6. REPAYMENT. Each loan made to a Participant who is receiving
regular payments of compensation from a Participating Employer shall be
repayable by payroll deduction. Loans made to other Participants (and, in all
events, where payroll deduction is no longer practicable) shall be repayable in
such manner as the Committee may from time to time determine. The documents
evidencing a loan shall provide that payments shall be made not less frequently
than quarterly and over a specified term as determined by the Committee (but not
to exceed five years; ten years if the loan is being applied toward the purchase
of a principal residence for the Participant); such documents shall also require
that the loan be amortized with level payments of principal and interest. A
Participant may prepay all, but not less than all, of his or her loan at any
time, without penalty, by paying the loan principal then outstanding together
with interest accrued and unpaid to the date of payment. Notwithstanding the
foregoing, loan repayments may be suspended with respect to a Participant during
any period he or she is performing qualified military service (as defined under
Code section 414(u)) in accordance with Code section 414(u)(4).

         7.7. REPAYMENT UPON DISTRIBUTION. If, at the time benefits are to be
distributed (or to commence being distributed) to a Participant with respect to
a severance from employment, there remains any unpaid balance of a loan
hereunder, such unpaid balance shall, to the extent consistent with Department
of Labor regulations, become immediately due and payable in full. Such unpaid
balance, together with any accrued but unpaid interest on the loan, shall be
deducted from the Participant's Accounts, subject to the default provisions
below, before any distribution of benefits is made. Except as may be required in
order to comply (in a manner consistent with continued qualification of the Plan
under Code section 401(a)) with Department of Labor regulations, no loan shall
be made or remain outstanding with respect to a Participant under this Article
after the time distributions to the Participant with respect to a severance from
employment are to be paid or commence.

         7.8. DEFAULT. In the event of a default in making any payment of
principal or interest when due under the note evidencing any loan under this
Article, if such default continues for more than 90 days of the due date
thereof, the unpaid principal balance of the note shall immediately become due
and payable in full. Such unpaid principal, together with any accrued but unpaid
interest, shall thereupon be deducted from the Participant's Accounts, subject
to the further provisions of this Section. The amount so deducted shall be
treated as distributed to the Participant and applied by the Participant as a
payment of the unpaid interest and principal (in that order) under the note
evidencing such loan. In no event shall the Committee apply the Participant's
Accounts to satisfy the Participant's repayment obligation, whether or not he or
she is in default, unless the amount so applied otherwise could be distributed
in accordance with the Plan.

         7.9. NOTE AS TRUST ASSET. The note evidencing a loan to a Participant
under this Article shall be an asset of the Trust which is allocated to the
Account of such Participant, and shall for purposes of the Plan be deemed to
have a value at any given time equal to the unpaid principal balance of the note
plus the amount of any accrued but unpaid interest.

                                     - 17 -

<PAGE>

         7.10. NONDISCRIMINATION. Loans shall be made available under this
Article to all Participants on a reasonably equivalent basis, except that the
Committee may make reasonable distinctions based on creditworthiness.

         7.11. DESIGNATION OF ACCOUNTS. Loans shall be made from the
Participant's Accounts in such order as may be designated by the Committee, and
loan repayments shall be credited to such Accounts in the same order. Loan
repayments shall be allocated among the investment options in accordance with
the Participant's then-effective instructions regarding the investment of
contributions made on his or her behalf.

         7.12. SPOUSAL CONSENT TO LOANS TO CERTAIN FORMER PARTICIPANTS IN OTHER
PLANS. In the case of a married Participant for whom amounts have been
transferred under Section 4.6 from a transferor plan and who has at any time
elected an annuity form of payment under Section 8.7 or under the transferor
plan, no loan shall be made unless (a) the Participant's spouse consents in
writing to such loan and to the use of the Participant's Accounts as security
for the loan, and such consent acknowledges the effect of the loan and the use
of the Accounts as security, is witnessed by a Plan representative or a notary
public, and is provided no more than 90 days before the date on which the loan
is to be secured by the Accounts, or (b) it is established to the satisfaction
of the Committee that the foregoing consent may not be obtained because there is
no spouse, because the spouse cannot be located, or because of such other
circumstances as the Secretary of the Treasury may prescribe.

          ARTICLE 8. BENEFITS UPON DEATH OR SEVERANCE FROM EMPLOYMENT

         8.1. SEVERANCE FROM EMPLOYMENT FOR REASONS OTHER THAN DEATH. Following
a Participant's severance from employment of an Affiliated Employer for any
reason other than death, the Participant will receive the vested portion of his
or her Accounts in cash in a single sum or, if the Participant elects and the
value of such portion exceeds $5,000, in monthly, quarterly, semi-annual, or
annual installments, fixed installments or variable installments over a period
certain not to exceed the Participant's life expectancy or the joint life and
last survivor expectancy of the Participant and his or her Beneficiary. An
election to receive monthly, quarterly, semi-annual, or annual installment
distributions in lieu of a single sum, and the period over which such
installments are to be made, shall be made by the Participant on a form approved
by the Committee. Notwithstanding the foregoing, for Plan Years beginning on or
after January 1, 2002, the installment options described above shall be
available only with respect to a Participant whose annuity starting date is
earlier than the earlier of (i) the 90th day after notice that such benefit
forms will no longer be available is provided in accordance with Regulation
section 1.411(d)-4, Q&A-2(e)(1) and (ii) the first day of the second Plan Year
following the Plan Year in which the form of optional benefit is eliminated by
amendment.

         8.2. TIME OF DISTRIBUTIONS. Distribution with respect to a
Participant's severance from employment normally will be made as soon as
practicable after such severance. In the case of a Participant whose Accounts
are valued in excess of $5,000 and who has not yet attained the Normal
Retirement Age, however, distribution may not be made under this Section unless

                  (a) between the 30th and 90th day prior to the date
         distribution is to be made, the Committee notifies the Participant in
         writing that he or she may defer distribution until the Normal
         Retirement Age; and

                  (b) the Participant consents to the distribution in writing
         after the information described above has been provided to him or her,
         and files such consent with the Committee.

Notwithstanding the foregoing, such distribution may commence less than 30 days
after the required notification described above is given, provided that (i) the
Committee clearly informs the Participant that the Participant has a right to a
period of at least 30 days after receiving the notice to consider whether or not
to elect a distribution; and (ii) the Participant, after receiving the notice,
elects a distribution.

A Participant's Accounts will be considered to be valued in excess of $5,000 if
the value of such Accounts exceeds such amount at the time of the distribution
in question. Distribution under this Section in all events will be made no later
than the 60th day after the close of the Plan Year in which occurs the later of
the Participant's severance from employment or the Participant's attainment of
the Normal Retirement Age.

         8.3. AMOUNT OF DISTRIBUTION.

                  (a) Single Sums. In the case of a distribution to be made in a
         single sum, the amount of the distribution shall be determined as of
         the Valuation Date on which authorized distribution directions are
         received by the Trustee.

                  (b) Installments. To the extent allowed in Section 8.1, in the
         case of distributions to be made in monthly, quarterly, semi-annual, or
         annual installments, the aggregate installment amount for a particular
         calendar year (the "installment year") shall be determined by dividing

                           (i) the value of the vested portion of the
                  Participant's Accounts as of the last Valuation Date preceding
                  the distribution date by

                           (ii) the lesser of (A) the number of remaining
                  installment years in the installment period elected by the
                  Participant as of the beginning of the installment year and
                  (B) the number of years in the applicable remaining life
                  expectancy for the installment year determined pursuant to
                  regulations under Code section 401(a)(9).

         8.4. DISTRIBUTIONS AFTER A PARTICIPANT'S DEATH.

                  (a) Death Prior to Severance From Employment. If a Participant
         dies prior to his or her severance from the service of the
         Participating Employers, the Participant's Beneficiary will receive the
         Participant's Accounts in either of the following forms, as elected by
         the Beneficiary on a form approved by the Committee:

                           (i) in cash in a single sum as soon as practicable
                  following the Participant's death (but in no event later than
                  December 31 of the calendar year following the year of the
                  Participant's death); or

                           (ii) in monthly, quarterly, semi-annual, or annual
                  installments over a period certain not to exceed the life
                  expectancy of the Beneficiary, such installments to begin not
                  later than December 31 of the calendar year following the year
                  of the Participant's death and to be made in amounts
                  determined in the same manner as under Section 8.3(b) above.

                  (b) Death After Severance From Employment. If a Participant
         dies after severance from employment but before the complete
         distribution of his or her Accounts has been made, the Participant's
         Beneficiary will receive the vested portion of the Participant's
         Accounts. Distribution will be made in cash in a single sum as soon as
         practicable following the Participant's death (but no later than
         December 31 of the calendar year following the year of the
         Participant's death) provided, however, that if distribution to the
         Participant had begun following his or her severance from employment in
         a form elected by the Participant, distribution will continue to be
         made to the Beneficiary at least as rapidly in such form unless the
         Beneficiary elects to receive the distribution in cash in a single sum
         as soon as practicable following the Participant's death. Any such
         election must be made on a

                                     - 20 -

<PAGE>

         form approved by the Committee and must be received by the Committee
         within such period following the Participant's death as the Committee
         may prescribe.

Any distribution to a Beneficiary under this Section shall be determined as of
the Valuation Date that authorized distribution directions are received by the
Trustee.

         8.5. DESIGNATION OF BENEFICIARY. Subject to the provisions of this
Section, a Participant's Beneficiary shall be the person or persons and entity
or entities, if any, designated by the Participant from time to time on a form
approved by the Committee. In the absence of an effective beneficiary
designation, the full amount payable upon the death of the Participant shall be
paid to his or her surviving spouse or, if none, to his or her estate. If any
Beneficiary survives the Participant but dies prior to receipt of his or her
interest in the Participant's Account, such Beneficiary's remaining interest
shall be paid to the Beneficiary's estate (unless the Participant had
effectively designated a successor or contingent Beneficiary for the
Beneficiary's remaining interest). A nonspouse beneficiary designation by a
Participant who is married at the time of his or her death shall not be
effective unless

                  (a) prior to the Participant's death, the Participant's
         surviving spouse consented to and acknowledged the effect of the
         Participant's designation of a specific non-spouse Beneficiary
         (including any class of Beneficiaries or any contingent Beneficiaries)
         on a written form approved by the Committee and witnessed by a notary
         public or a duly authorized Plan representative; or

                  (b) it is established to the satisfaction of the Committee
         that spousal consent may not be obtained because there is no spouse,
         because the spouse has died (evidenced by a certificate of death),
         because the spouse cannot be located (based on information supplied by
         a government agency or independent investigator), or because of such
         other circumstances as the Secretary of the Treasury may prescribe; or

                  (c) the spouse had earlier executed a general consent form
         permitting the Participant (i) to select from among certain specified
         beneficiaries without any requirement of further consent by the spouse
         (and the Participant designates a Beneficiary from the specified list),
         or (ii) to change his or her Beneficiary without any requirement of
         further consent by the spouse. Any such general consent shall be on a
         form approved by the Committee, and must acknowledge that the spouse
         has the right to limit consent to a specific beneficiary and that the
         spouse voluntarily elects to relinquish such right.

In the event a spouse is legally incompetent to give consent, the spouse's legal
guardian, even if the guardian is the Participant, may give consent on behalf of
the spouse. Any consent and acknowledgment by (or on behalf of) a spouse, or the
establishment that the consent and acknowledgment cannot be obtained, shall be
effective only with respect to such spouse, but shall be irrevocable once made.

         8.6. DIRECT ROLLOVERS OF ELIGIBLE DISTRIBUTIONS. Notwithstanding any
provision of the Plan to the contrary that may otherwise limit a distributee's
election under this Section, a distributee

                                     - 21 -

<PAGE>

may elect, at the time and in the manner prescribed by the Committee, to have
any portion of an eligible rollover distribution paid directly to an eligible
retirement plan specified by the distributee in a direct rollover. For purposes
of this Section, the following terms have the following meanings:

                  (a) an "eligible rollover distribution" is any distribution of
         all or any portion of the balance to the credit of the distributee,
         except that an eligible rollover distribution does not include: any
         distribution that is one of a series of substantially equal periodic
         payments (not less frequently than annually) made for the life (or life
         expectancy) of the distributee or the joint lives of the distributee
         and the distributee's Beneficiary, or for a specified period of ten
         years or more; any distribution to the extent such distribution is
         required under Code section 401(a)(9); any distribution that is made on
         account of hardship; and the portion of any distribution that is not
         includible in gross income (determined without regard to the exclusion
         for net unrealized appreciation with respect to employer securities).
         Notwithstanding the foregoing, with respect to distributions made after
         December 31, 2001, a portion of a distribution shall not fail to be an
         eligible rollover distribution merely because the portion consists of
         after-tax Employee Contributions which are not includible in gross
         income. However, such portion may be transferred only to an individual
         retirement account or annuity described in section 408(a) or (b) of the
         Code, or to a qualified defined contribution plan described in section
         401(a) or 403(a) of the Code that agrees to account separately for
         amounts so transferred, including separately accounting for the portion
         of such distribution which is includible in gross income and the
         portion of such distribution which is not so includible.

                  (b) with respect to a distributee, an "eligible retirement
         plan" is an individual retirement account described in Code section
         408(a), an individual retirement annuity described in Code section
         408(b), an annuity plan described in Code section 403(a), or a
         qualified trust described in Code section 401(a). With respect to
         distributions made after December 31, 2001, an "eligible retirement
         plan" shall also mean an annuity contract described in section 403(b)
         of the Code and an eligible plan under section 457(b) of the Code which
         is maintained by a state, political subdivision of a state, or any
         agency or instrumentality of a state or political subdivision of a
         state and which agrees to account separately for amounts transferred
         into such plan from this Plan. Notwithstanding the foregoing, for
         distributions prior to January 1, 2002, with respect to a distributee
         who is a Participant's surviving spouse or a spouse or former spouse
         who is the alternate payee under a qualified domestic relations order
         as defined in section 414(p) of the Code, an eligible retirement plan
         is only an individual retirement account or an individual retirement
         annuity.

                  (c) a "distributee" includes an employee or former employee.
         In addition, the employee's or former employee's surviving spouse and
         the employee's or former employee's spouse or former spouse, who is an
         alternate payee under a Qualified Domestic Relations Order, are
         distributees with regard to the interest of the spouse or former

                  (d) a "direct rollover" is a payment by the Plan to the
         eligible retirement plan specified by the distributee.

         8.7. PROTECTED FORMS OF BENEFIT. Notwithstanding any provision of this
Plan to the contrary, in the event that the Plan Sponsor directs the Trustee to
accept Plan assets for the benefit of Participants from another qualified
retirement plan in connection with a merger or acquisition, or the adoption of
the Plan by a Participating Employer, the Account balance attributable to such
benefit shall be payable in the benefit form or forms so provided under the
predecessor plan to the extent required by Code section 411(d)(6) and
Regulations promulgated thereunder, or any successor Code provision (which forms
of benefits shall be set forth on Schedule B to this Plan and identified with
the appropriate Participating Employer); provided that, a form of benefit shall
be retained pursuant to this Section only with respect to a Participant whose
annuity starting date is earlier than the earlier of (i) the 90th day after
notice that such form of optional benefit will no longer be available is
provided in accordance with Regulation section 1.411(d)-4, Q&A-2(e)(1) and (ii)
the first day of the second Plan Year following the Plan Year in which the term
of optional benefit is eliminated by amendment.

         8.8. DISTRIBUTION RESTRICTIONS FOR ELECTIVE CONTRIBUTIONS.
Notwithstanding anything in the Plan to the contrary, a Participant's Elective
Contribution Account shall be distributable only in accordance with Code section
401(k).

                           ARTICLE 9. ADMINISTRATION.

         9.1. COMMITTEE. The Plan will be administered by a committee of
individuals selected by the Board of Directors to serve at its pleasure. The
Committee will be a "named fiduciary" for purposes of Section 402(a)(1) of ERISA
with authority to control and manage the operation and administration of the
Plan, and will be responsible for complying with all of the reporting and
disclosure requirements of Part 1 of Subtitle B of Title I of ERISA. The
Committee will not, however, have any authority over the investment of assets of
the Trust in its capacity as Committee.

         9.2. POWERS OF COMMITTEE. The Committee will have full discretionary
power to administer the Plan in all of its details, subject, however, to the
requirements of ERISA. For this purpose the Committee's discretionary power will
include, but will not be limited to, the following authority:

                  (a) to make and enforce such rules and regulations as it deems
         necessary or proper for the efficient administration of the Plan or
         required to comply with applicable law;

                  (b) to interpret the Plan;

                  (c) to decide all questions concerning the Plan and the
         eligibility of any person to participate in the Plan;

                  (d) to compute the amounts to be distributed under the Plan,
         and to determine the person or persons to whom such amounts will be
         distributed;

                  (e) to authorize the payment of distributions;

                  (f) to keep such records and submit such filings, elections,
         applications, returns or other documents or forms as may be required
         under the Code and applicable regulations, or under other federal,
         state or local law and regulations;

                  (g) to allocate and delegate its ministerial duties and
         responsibilities and to appoint such agents, counsel, accountants and
         consultants as may be required or desired to assist in administering
         the Plan; and

                  (h) to allocate and delegate its fiduciary responsibilities in
         accordance with ERISA section 405.

         9.3. EFFECT OF INTERPRETATION OR DETERMINATION. Any interpretation of
the Plan or other determination with respect to the Plan by the Committee shall
be final and conclusive on all persons in the absence of clear and convincing
evidence that the Committee acted arbitrarily and capriciously.

         9.4. RELIANCE ON TABLES, ETC. In administering the Plan, the Committee
will be entitled, to the extent permitted by law, to rely conclusively on all
tables, valuations, certificates, opinions and reports which are furnished by
any accountant, trustee, counsel or other expert who is employed or engaged by
the Committee or by the Plan Sponsor on the Committee's behalf.

         9.5. CLAIMS AND REVIEW PROCEDURES. The Committee shall adopt procedures
for the filing and review of claims in accordance with ERISA section 503.

         9.6. INDEMNIFICATION OF COMMITTEE AND ASSISTANTS. Each Participating
Employer agrees, jointly and severally, to indemnify and defend to the fullest
extent of the law any Employee or former Employee (a) who serves or has served
as a Committee member, (b) who has been appointed to assist the Committee in
administering the Plan, or (c) to whom the Committee has delegated any of its
duties or responsibilities against any liabilities, damages, costs and expenses
(including attorneys' fees and amounts paid in settlement of any claims approved
by the Plan Sponsor) occasioned by any act or omission to act in connection with
the Plan, if such act or omission to act is in good faith and without gross
negligence.

         9.7. ANNUAL REPORT. The Committee shall submit annually to the Plan
Sponsor a report showing in reasonable summary form, the financial position of
the Trust and giving a brief account of the operations of the Plan for the past
year, and such further information as the Plan Sponsor may reasonably require.

                     ARTICLE 10. AMENDMENT AND TERMINATION.

         10.1. AMENDMENT. The Plan Sponsor reserves the power at any time or
times to amend the provisions of the Plan and Trust to any extent and in any
manner that it may deem advisable. Upon delivery to the Trustee and each
Participating Employer of an amendment adopted by the Board of Directors, the
Plan shall be amended at the time and in the manner set forth therein, and all
Participants and all persons claiming an interest hereunder shall be bound
thereby. Notwithstanding the foregoing, no action by the Board of Directors
shall be required to amend the Plan to revise Schedule A, regarding the addition
or removal of Participating Employers, or Schedule B, regarding a merger of, or
transfer of accounts from, another plan into the Plan. Moreover, the Plan
Sponsor may amend or modify any plan provisions which relate to ERISA section
404(c) compliance, including changes which would eliminate the Plan's status as
an ERISA section 404(c) plan. However, the Plan Sponsor will not have the power:

                  (a) to amend the Plan or Trust in such manner as would cause
         or permit any part of the assets of the Trust to be diverted to
         purposes other than for the exclusive benefit of each Participant and
         his or her Beneficiary (except as permitted by the Plan with respect to
         Qualified Domestic Relations Orders or the return of contributions upon
         nondeductibility, mistake of fact, or the failure to qualify
         initially), unless such amendment is required or permitted by law,
         governmental regulation or ruling; or

                  (b) to amend the Plan or Trust retroactively in such a manner
         as would reduce the accrued benefit of any Participant, except as
         otherwise permitted or required by law. For purposes of this paragraph,
         an amendment which has the effect of decreasing a Participant's Account
         balance or eliminating an optional form of benefit, with respect to
         benefits attributable to service before the amendment, shall be treated
         as reducing an accrued benefit.

         10.2. TERMINATION. The Plan Sponsor has established the Plan and
authorized the establishment of the Trust with the bona fide intention and
expectation that contributions will be continued indefinitely, but may
discontinue contributions under the Plan or terminate the Plan at any time by
written notice delivered to the Trustee without liability whatsoever for any
such discontinuance or termination. In addition, the Participating Employers
will have no obligation or liability whatsoever to maintain the Plan for any
given length of time and may cease to be Participating Employers in a manner
acceptable to the Plan Sponsor.

         10.3. DISTRIBUTIONS UPON TERMINATION OF THE PLAN. Upon termination of
the Plan by the Plan Sponsor, the Trustee will distribute to each Participant
(or other person entitled to distribution) the value of the Participant's
Accounts in a single sum as soon as practicable following such termination. The
amount of such distribution shall be determined as of the Valuation Date that
authorized distribution directions are received by the Trustee.

         10.4. MERGER OR CONSOLIDATION OF PLAN; TRANSFER OF PLAN ASSETS. In case
of any merger or consolidation of the Plan with, or transfer of assets and
liabilities of the Plan to, any other plan, provision must be made so that each
Participant would, if the Plan then terminated, receive a benefit immediately
after the merger, consolidation or transfer which is equal to or greater than
the benefit he or she would have been entitled to receive immediately before the
merger, consolidation or transfer if the Plan had then terminated.

                      ARTICLE 11. LIMITS ON CONTRIBUTIONS.

         11.1. CODE SECTION 404 LIMITS. The sum of the contributions made by
each Participating Employer under the Plan for any Plan Year shall not exceed
the maximum amount deductible under the applicable provisions of the Code. All
contributions under the Plan made by a Participating Employer are expressly
conditioned on their deductibility under Code section 404 for the taxable year
when paid (or treated as paid under Code section 404(a)(6)).

         11.2. CODE SECTION 415 LIMITS.

                  (a) Incorporation by reference. Code section 415 is hereby
         incorporated by reference into the Plan.

                  (b) Annual addition. The Committee shall determine an "annual
         addition" for each Participant for each limitation year, which shall
         consist of the following amounts:

                           (i) Elective Contributions allocated to the
                  Participant's Accounts for the year;

                           (ii) Matching Contributions allocated to the
                  Participant's Accounts for the year;

                           (iii) Qualified Nonelective Contributions allocated
                  to the Participant's Accounts for the year;

                           (iv) Employee Contributions allocated to the
                  Participant's Accounts for the year;

                           (v) forfeitures;

                           (vi) amounts allocated to an individual medical
                  amount (as defined in Code section 415(l)(2)) which is part of
                  a pension or annuity plan maintained by an Affiliated
                  Employer; and

                           (vii) amounts derived from contributions paid or
                  accrued which are attributable to post-retirement medical
                  benefits allocated to the separate account of a key employee
                  (as defined in Code section 419A(d)(3)) under a welfare
                  benefit fund (as defined in Code section 419(e)) maintained by
                  an Affiliated Employer.

                  (c) General limitation on annual additions. The annual
         addition of a Participant under (b) above for any limitation year, when
         added to the annual additions to his or her accounts for such year
         under all other defined contribution plans maintained by the Affiliated
         Employers, shall not exceed the lesser of (i) $30,000 (increased from
         time to time in accordance with Code section 415(d)), or (ii) 25% of
         the Participant's Compensation for such limitation year. For Plan Years
         beginning on or after January 1, 2002, the amount in (i) above shall be
         $40,000 (increased from time to time in accordance with Code section
         415(d) and the amount in (ii) above shall be 100% of the Participant's
         Compensation for

                                     - 27 -

<PAGE>

         such limitation year (or such other percentage as provided by Code
         section 415). The compensation limit referred to in (ii) above shall
         not apply to any contribution for medical benefits after separation
         from service (within the meaning of section 401(h) or section
         419A(f)(2) of the Code), which is otherwise treated as an annual
         addition.

                  (d) Limitation Year. For purposes of determining the Code
         section 415 limits under the Plan, the "limitation year" shall be the
         Plan Year.

                  (e) Order of reductions. To the extent necessary to satisfy
         the limitations of Code section 415 for any Participant, the annual
         addition which would otherwise be made on behalf of the Participant
         under the Plan shall be reduced before the Participant's benefit is
         reduced under any and all defined benefit plans, and before the
         Participant's annual addition is reduced under any other defined
         contribution plan.

                  (f) Return of excess contributions. If, as a result of a
         reasonable error in estimating a Participant's Compensation for a Plan
         Year or limitation year, a reasonable error in determining the amount
         of elective deferrals (within the meaning of Code section 402(g)(3))
         that may be made with respect to any individual under the limits of
         Code section 415, or under such other facts and circumstances as may be
         permitted under regulation or by the Internal Revenue Service, the
         annual addition under the Plan for a Participant would cause the Code
         section 415 limitations for a limitation year to be exceeded, the
         excess amounts shall be treated in accordance with the rules provided
         in Internal Revenue Service Reg. Section 1.415-6(b)(6).

         11.3. CODE SECTION 402(G) LIMITS.

                  (a) In general. The maximum amount of Elective Contributions
         made on behalf of any Participant for any calendar year, when added to
         the amount of elective deferrals under all other plans, contracts and
         arrangements of an Affiliated Employer with respect to the Participant
         for the calendar year), shall in no event exceed the maximum applicable
         limit in effect for the calendar year under Regulation section
         1.402(g)-1(d). For purposes of the Plan, an individual's elective
         deferrals for a taxable year are the sum of the following:

                           (i) Any elective contribution under a qualified cash
                  or deferred arrangement (as defined in Code section 401(k)) to
                  the extent not includible in the individual's gross income for
                  the taxable year on account of Code section 402(a)(8) (before
                  applying the limits of Code section 402(g) or this section);

                           (ii) Any employer contribution to a simplified
                  employee pension (as defined in code section 408(k) to the
                  extent not includible in the individual's gross income for the
                  taxable year on account of Code section 402(h)(1)(B) (before
                  applying the limits of Code section 402(g)); and

                           (iii) Any employer contribution to a custodial
                  account or annuity contract under section 403(b) under a
                  salary reduction agreement (within the meaning of Code section
                  3121(a)(5)(D)), to the extent not includible in the
                  individual's gross

                                     - 28 -

<PAGE>

                  income for the taxable year on account of Code section 403(b)
                  before applying the limits of Code section 402(g).

         A Participant will be considered to have made "excess deferrals" for a
         taxable year to the extent that the Participant's elective deferrals
         for the taxable year exceed the applicable limit described above for
         the year.

                  (b) Distribution of excess deferrals. In the event that an
         amount is included in a Participant's gross income for a taxable year
         as a result of an excess deferral under Code section 402(g), and the
         Participant notifies the Committee on or before the March 1 following
         the taxable year that all or a specified part of an Elective
         Contribution made for his or her benefit represents an excess deferral,
         the Committee shall make every reasonable effort to cause such excess
         deferral, adjusted for allocable income, to be distributed to the
         Participant no later than the April 15 following the calendar year in
         which such excess deferral was made. The income allocable to excess
         deferrals is equal to the allocable gain or loss for the taxable year
         of the individual, but not the allocable gain or loss for the period
         between the end of the taxable year and the date of distribution (the
         "gap period"). Income allocable to excess deferrals for the taxable
         year shall be determined by multiplying the gain or loss attributable
         to the Participant's Elective Contribution Account for the taxable year
         by a fraction, the numerator of which is the Participant's excess
         deferrals for the taxable year, and the denominator of which is the sum
         of the Participant's Elective Contribution Account balance as of the
         beginning of the taxable year plus the Participant's Elective
         Contributions for the taxable year. No distribution of an excess
         deferral shall be made during the taxable year of a Participant in
         which the excess deferral was made unless the correcting distribution
         is made after the date on which the Plan received the excess deferral
         and both the Participant and the Plan designate the distribution as a
         distribution of an excess deferral. The amount of any excess deferrals
         that may be distributed to a Participant for a taxable year shall be
         reduced by the amount of Elective Contributions that were excess
         contributions and were previously distributed to the Participant for
         the Plan Year beginning with or within such taxable year.

                  (c) Treatment of excess deferrals. For other purposes of the
         Code, including Code sections 401(a)(4), 401(k)(3), 404, 409, 411, 412,
         and 416, excess deferrals must be treated as employer contributions
         even if they are distributed in accordance with paragraph (b) above.
         However, excess deferrals of a non-Highly Compensated Employee are not
         to be taken into account for purposes of Code section 401(k)(3) (the
         actual deferral percentage test) to the extent the excess deferrals are
         prohibited under Code section 401(a)(30). Excess deferrals are also to
         be treated as employer contributions for purposes of Code section 415
         unless distributed under paragraph (b) above.

         11.4. CODE SECTION 401(K)(3) LIMITS.

                  (a) In general. Elective Contributions made under the Plan are
         subject to the limits of Code section 401(k)(3), as more fully
         described below. The Plan provisions relating to the 401(k)(3) limits
         are to be interpreted and applied in accordance with Code sections
         401(k)(3) and 401(a)(4), which are hereby incorporated by reference,
         and in such manner as

                                     - 29 -

<PAGE>

         to satisfy such other requirements relating to Code section 401(k) as
         may be prescribed by the Secretary of the Treasury from time to time.

                  (b) Actual deferral ratios. For each Plan Year, the Committee
         will determine the "actual deferral ratio" for each Participant who is
         eligible for Elective Contributions. The actual deferral ratio shall be
         the ratio, calculated to the nearest one-hundredth of one percent, of
         the Elective Contributions (plus any Qualified Nonelective
         Contributions treated as Elective Contributions) made on behalf of the
         Participant for the Plan Year to the Participant's Compensation for the
         Plan Year. For purposes of determining a Participant's actual deferral
         ratio,

                           (i) Elective Contributions will be taken into account
                  only if each of the following requirements are satisfied:

                                    (A) the Elective Contribution is allocated
                           to the Participant's Elective Contribution Account as
                           of a date within the Plan Year is not contingent upon
                           participation in the Plan or performance of services
                           on any date subsequent to that date, and is actually
                           paid to the Trust no later than the end of the
                           12-month period immediately following the Plan Year
                           to which the contribution relates; and

                                    (B) the Elective Contribution relates to
                           Compensation that either would have been received by
                           the Participant in the Plan Year but for the
                           Participant's election to defer under the Plan, or is
                           attributable to services performed in the Plan Year
                           and, but for the Participant's election to defer,
                           would have been received by the Participant within 2
                           1/2 months after the close of the Plan Year.

                  To the extent Elective Contributions which meet the
                  requirements of (A) and (B) above constitute excess deferrals,
                  they will be taken into account for each Highly Compensated
                  Employee, but will not be taken into account for any
                  non-Highly Compensated Employee;

                           (ii) in the case of a Participant who is a Highly
                  Compensated Employee for the Plan Year and is eligible to have
                  elective deferrals (and qualified nonelective contributions,
                  to the extent treated as elective deferrals) allocated to his
                  or her accounts under two or more cash or deferred
                  arrangements described in Code section 401(k) maintained by an
                  Affiliated Employer, the Participant's actual deferral ratio
                  shall be determined as if such elective deferrals (as well as
                  qualified nonelective or qualified) are made under a single
                  arrangement, and if two or more of the cash or deferred
                  arrangements have different Plan Years, all Plan Years ending
                  with or within the same calendar year shall be treated as a
                  single Plan Year;

                           (iii) the applicable period for determining
                  Compensation for each Participant for a Plan Year shall be the
                  12-month period ending on the last day of such Plan Year;
                  provided, that to the extent permitted under Regulations, the
                  Committee may

                                     - 30 -

<PAGE>

                  choose, on a uniform basis, to treat as the applicable period
                  only that portion of the Plan Year during which the individual
                  was eligible to make Elective Contributions;

                           (iv) Qualified Nonelective Contributions made on
                  behalf of Participants who are eligible to receive Elective
                  Contributions shall be treated as Elective Contributions to
                  the extent permitted by Regulation section 1.401(k)-1(b)(5);

                           (v) in the event that the Plan satisfies the
                  requirements of Code sections 401(k), 410(a)(4), or 410(b)
                  only if aggregated with one or more other plans with the same
                  plan year, or if one or more other plans with the same Plan
                  Year satisfy such Code sections only if aggregated with this
                  Plan, then this section shall be applied by determining the
                  actual deferral ratios as if all such plans were a single
                  plan;

                           (vi) An employee who would be a Participant but for
                  the failure to make Elective Contributions shall be treated as
                  a Participant on whose behalf no Elective Contributions are
                  made; and

                           (vii) Elective Contributions which are made on behalf
                  of non-Highly Compensated Employees which could be used to
                  satisfy the Code section 401(k)(3) limits but are not
                  necessary to be taken into account in order to satisfy such
                  limits, may instead be taken into account for purposes of the
                  Code section 401(m) limits to the extent permitted by
                  Regulation sections 1.401(m)-1(b)(5).

                  (c) Actual deferral percentages. Each Plan Year, the actual
         deferral ratios for all Highly Compensated Employees who are eligible
         for Elective Contributions for a Plan Year shall be averaged to
         determine the actual deferral percentage for the highly compensated
         group for the Plan Year, and the actual deferral ratios for all
         Employees who are not Highly Compensated Employees but are eligible for
         Elective Contributions for the Plan Year shall be averaged to determine
         the actual deferral percentage for the nonhighly compensated group for
         the Plan Year.

                  (d) Actual deferral percentage tests. For a Plan Year, at
         least one of the following tests must be satisfied:

                           (i) the highly compensated group's actual deferral
                  percentage for the Plan Year does not exceed 125% of the prior
                  year actual deferral percentage for the prior year nonhighly
                  compensated group; or

                           (ii) the excess of the actual deferral percentage for
                  the highly compensated group for the Plan Year over the prior
                  year actual deferral percentage for the prior year nonhighly
                  compensated group does not exceed two percentage points, and
                  the actual deferral percentage for the highly compensated
                  group for the Plan Year does not exceed twice the prior year
                  actual deferral percentage for the prior year nonhighly
                  compensated group.

         For purposes of satisfying the above tests for a Plan Year, the "prior
         year actual deferral percentage for the prior year nonhighly
         compensated group" refers to the actual deferral

                                     - 31 -

<PAGE>

         percentage determined for the immediately preceding Plan Year for the
         nonhighly compensated group existing during such preceding Plan Year.
         Notwithstanding the foregoing, in satisfying the above tests, the
         Committee may elect, in accordance with Code section 401(k)(3) and
         applicable regulations, to use the actual deferral percentage for the
         nonhighly compensated group determined for the current Plan Year.

                  (e) Adjustments by Committee. If, prior to the time all
         Elective Contributions for a Plan Year have been contributed to the
         Trust, the Committee determines that Elective Contributions are being
         made at a rate which will cause the Code section 401(k)(3) limits to be
         exceeded for the Plan Year, the Committee may, in its sole discretion,
         limit the amount of Elective Contributions to be made with respect to
         one or more Highly Compensated Employees for the balance of the Plan
         Year by suspending or reducing Elective Contribution elections to the
         extent the Committee deems appropriate. Any Elective Contributions
         which would otherwise be made to the Trust shall instead be paid to the
         affected Participant in cash.

                  (f) Excess contributions. If the Code section 401(k)(3) limits
         have not been met for a Plan Year after all contributions for the Plan
         Year have been made, the Committee will determine the amount of excess
         contributions with respect to Participants who are Highly Compensated
         Employees in the manner prescribed by Code section 401(k)(8) and by
         applicable regulations.

                  (g) Distribution of excess contributions. A Participant's
         excess contributions, adjusted for income, will be designated by the
         Participating Employer as a distribution of excess contributions and
         distributed to the Participant. The income allocable to excess
         contributions is equal to the allocable gain or loss for the Plan Year,
         but not the allocable gain or loss for the period between the end of
         the Plan Year and the date of distribution (the "gap period"). Income
         allocable to excess contributions for the Plan Year shall be determined
         by multiplying the gain or loss attributable to the Participant's
         Elective Contribution Account and QNEC Account balances by a fraction,
         the numerator of which is the excess contributions for the Participant
         for the Plan Year, and the denominator of which is the sum of the
         Participant's Elective Contribution Account and QNEC Account balances
         as of the beginning of the Plan Year plus the Participant's Elective
         Contributions and Qualified Nonelective Contributions for the Plan
         Year. Distribution of excess contributions will be made after the close
         of the Plan Year to which the contributions relate, but within 12
         months after the close of such Plan Year. Excess contributions shall be
         treated as annual additions under the Plan, even if distributed under
         this paragraph.

                  (h) Special rules. For purposes of distributing excess
         contributions, the amount distributed with respect to a Highly
         Compensated Employee for a Plan Year shall be reduced by the amount of
         excess deferrals previously distributed to the Highly Compensated
         Employee for his or her taxable year ending with or within such Plan
         Year.

                  (i) Recordkeeping requirement. The Committee, on behalf of the
         Participating Employers, shall maintain such records as are necessary
         to demonstrate compliance with the

                                     - 32 -

<PAGE>

         Code section 401(k)(3) limits, including the extent to which Qualified
         Nonelective Contributions are taken into account in determining the
         actual deferral ratios.

                  (j) Excise tax where failure to correct. If the excess
         contributions are not corrected within 2 1/2 months after the close of
         the Plan Year to which they relate, the Participating Employers will be
         liable for a 10 percent excise tax on the amount of excess
         contributions attributable to them, to the extent provided by Code
         section 4979. Qualified Nonelective Contributions properly taken into
         account under this Section for the Plan Year may enable the Plan to
         avoid having excess contributions, even if the contributions are made
         after the close of the 2 1/2 month period.

         11.5. CODE SECTION 401(m) LIMITS.

                  (a) In General. Matching Contributions made under the Plan are
         subject to the limits of Code section 401(m), as more fully described
         below. The Plan provisions relating to the 401(m) limits are to be
         interpreted and applied in accordance with Code sections 401(m) and
         401(a)(4), which are hereby incorporated by reference, and in such
         manner as to satisfy such other requirements relating to Code section
         401(m) as may be prescribed by the Secretary of the Treasury from time
         to time.

                  (b) Actual contribution ratios. For each Plan Year, the
         Administrator will determine the "actual contribution ratio" for each
         Participant who is eligible for Matching Contributions. The actual
         contribution ratio shall be the ratio, calculated to the nearest
         one-hundredth of one percent, of the sum of the Matching Contributions
         and Qualified Nonelective Contributions which are not treated as
         Elective Contributions made on behalf of the Participant for the Plan
         Year, to the Participant's Compensation for the Plan Year. For purposes
         of determining a Participant's actual contribution ratio,

                           (i) A Matching Contribution will be taken into
                  account only if the Contribution is allocated to a
                  Participant's Account as of a date within the Plan Year, is
                  actually paid to the Trust no later than 12 months after the
                  close of the Plan Year, and is made on behalf of a Participant
                  on account of the Participant's Elective Contributions for the
                  Plan Year;

                           (ii) in the case of a Participant who is a Highly
                  Compensated Employee for the Plan Year and is eligible to have
                  Matching Contributions or employee contributions (including
                  amount treated as Matching Contributions) allocated to his or
                  her accounts under two or more plans maintained by an
                  Affiliated Employer which may be aggregated for purposes of
                  Code sections 410(b) and 401(a)(4), the Participant's actual
                  contribution ratio shall be determined as if such
                  contributions are made under a single plan, and if two or more
                  of the plans have different Plan Years, all Plan Years ending
                  with or within the same calendar year shall be treated as a
                  single Plan Year;

                           (iii) the applicable period for determining
                  Compensation for each Participant for a Plan Year shall be the
                  12-month period ending on the last day of such Plan Year;
                  provided that to the extent permitted under Regulations, the
                  Administrator

                                     - 33 -

<PAGE>

                  may choose, on a uniform basis, to treat as the applicable
                  period only that portion of the Plan Year during which the
                  individual was eligible for Matching Contributions;

                           (iv) Elective Contributions not applied to satisfy
                  the Code section 401(k)(3) limits and Qualified Nonelective
                  Contributions not treated as Elective Contributions may be
                  treated as Matching Contributions to the extent permitted by
                  Regulation section 1.401(m)-1(b)(5);

                           (v) in the event that the Plan satisfies the
                  requirements of Code sections 401(k), 410(a)(4), or 410(b)
                  only if aggregated with one or more other plans with the same
                  Plan Year, or if one or more other plans with the same Plan
                  Year satisfy such Code sections only if aggregated with this
                  Plan, then this section shall be applied by determining the
                  actual deferral ratios as if all such plans were a single
                  plan; and

                           (vi) any forfeitures under the Plan which are applied
                  against Matching Contributions shall be treated as Matching
                  Contributions.

                  (c) Actual contribution percentages. Each Plan Year, the
         actual contribution ratios for all Highly Compensated Employees who are
         eligible for Matching Contributions for a Plan Year shall be averaged
         to determine the actual contribution percentage for the highly
         compensated group for the Plan Year, and the actual contribution ratios
         for all Employees who are not Highly Compensated Employees but are
         eligible for Matching Contributions for the Plan Year shall be averaged
         to determine the actual contribution percentage for the nonhighly
         compensated group for the Plan Year.

                  (d) Actual contribution percentage tests. For a Plan Year, at
         least one of the following tests must be satisfied:

                           (i) the highly compensated group's actual
                  contribution percentage for the Plan Year does not exceed 125%
                  of the prior year actual contribution percentage for the prior
                  year nonhighly compensated group; or

                           (ii) the excess of the actual contribution percentage
                  for the highly compensated group for the Plan Year over the
                  prior year actual contribution percentage for the prior year
                  nonhighly compensated group does not exceed two percentage
                  points, and the actual contribution percentage for the highly
                  compensated group for the Plan Year does not exceed twice the
                  prior year actual contribution percentage for the prior year
                  nonhighly compensated group.

         For purposes of satisfying the above tests for a Plan Year, the "prior
         year actual contribution percentage for the prior year nonhighly
         compensated group" refers to the actual contribution percentage
         determined for the immediately preceding Plan Year for the nonhighly
         compensated group existing during such preceding Plan Year.
         Notwithstanding the foregoing, in satisfying the above tests, the
         Committee may elect, in accordance with Code section 401(m)(2) and
         applicable regulations, to use the actual contribution percentage for
         the nonhighly compensated group calculated for the current Plan Year.

<PAGE>

                  (e) Multiple use test. In the event that (i) the actual
         deferral percentage and actual contribution percentage for the highly
         compensated group exceed 125% of the respective actual deferral and
         actual contribution percentages for the nonhighly compensated group,
         and (ii) the sum of the actual deferral percentage and the actual
         contribution percentage for the highly compensated group exceeds the
         "aggregate limit" within the meaning of Regulation section
         1.401(m)-2(b)(3), the Administrator shall reduce the actual
         contribution ratios of Highly Compensated Employees who had both an
         actual deferral ratio and an actual contribution ratio for the Plan
         Year to the extent required by such section and in the same manner as
         described in paragraph (f) below. The multiple use test described in
         Treasure Regulation section 401(m)-2 and this Section shall not apply
         for Plan Years beginning after December 31, 2001.

                  (f) Adjustments by Administrator. If, prior to the time all
         Matching Contributions for a Plan Year have been contributed to the
         Trust, the Administrator determines that such contributions are being
         made at a rate which will cause the Code section 401(m) limits to be
         exceeded for the Plan Year, the Administrator may, in its sole
         discretion, limit the amount of such contributions to be made with
         respect to one or more Highly Compensated Employees for the balance of
         the Plan Year by limiting the amount of such contributions to the
         extent the Administrator deems appropriate.

                  (g) Excess aggregate contributions. If the Code section 401(m)
         limits have not been satisfied for a Plan Year after all contributions
         for the Plan Year have been made, the excess of the aggregate amount of
         the Matching

         Contributions (and any Qualified Nonelective Contribution or elective
         deferral taken into account in computing the actual contribution
         percentages) actually made on behalf of Highly Compensated Employees
         for the Plan Year over the maximum amount of such contributions
         permitted under Code section 401(m)(2)(A) shall be considered to be
         "excess aggregate contributions". The Committee will determine the
         amount of excess aggregate contributions with respect to Participants
         who are Highly Compensated Employees in the manner prescribed by Code
         section 401(m)(6)(C) and by applicable regulations

                  (h) Distribution of excess aggregate contributions. A
         Participant's excess aggregate contributions, adjusted for income, will
         be designated by the Participating Employer as a distribution of excess
         aggregate contributions, and distributed to the Participant. The income
         allocable to excess aggregate contributions is equal to the allocable
         gain or loss for the taxable year of the individual, but not the
         allocable gain or loss for the period between the end of the taxable
         year and the date of distribution (the "gap period"). Income allocable
         to excess aggregate contributions for the taxable year shall be
         determined by multiplying the gain or loss attributable to the
         Participant's Matching Contribution Account balances by a fraction, the
         numerator of which is the excess aggregate contributions for the
         Participant for the Plan Year, and the denominator of which is the sum
         of the Participant's Matching Contribution Account balances as of the
         beginning of the Plan Year plus the Participant's Matching
         Contributions for the Plan Year. Distribution of excess aggregate
         contributions will be made after the close of the Plan Year to which
         the contributions relate, but within 12 months after the close of such
         Plan Year. Excess aggregate contributions shall be treated as

                                     - 35 -

<PAGE>

         employer contributions for purposes of Code sections 401(a)(4), 404,
         and 415 even if distributed from the Plan.

                  (i) Recordkeeping requirement. The Administrator, on behalf of
         the Participating Employers, shall maintain such records as are
         necessary to demonstrate compliance with the Code section 401(m)
         limits, including the extent to which Elective Contributions and
         Qualified Nonelective Contributions are taken into account in
         determining the actual contribution ratios.

                  (j) Excise tax where failure to correct. If the excess
         aggregate contributions are not corrected within 2 1/2 months after the
         close of the Plan Year to which they relate, the Participating
         Employers will be liable for a 10 percent excise tax on the amount of
         excess aggregate contributions attributable to them, to the extent
         provided by Code section 4979. Qualified Nonelective Contributions
         properly taken into account under this section for the Plan Year may
         enable the Plan to avoid having excess aggregate contributions, even if
         the contributions are made after the close of the 2 1/2 month period.

                   ARTICLE 12. SPECIAL TOP-HEAVY PROVISIONS.

         12.1. PROVISIONS TO APPLY. The provisions of this Article shall apply
for any top-heavy Plan Year notwithstanding anything to the contrary in the
Plan.

         12.2. MINIMUM CONTRIBUTION. For any Plan Year which is a top-heavy plan
year, the Participating Employers shall contribute to the Trust a minimum
contribution on behalf of each Participant who is not a key employee for such
year and who has not separated from service from the Affiliated Employers by the
end of the Plan Year, regardless of whether or not the Participant has elected
to make Elective Contributions for the Year. The minimum contribution shall, in
general, equal 3% of each such Participant's Compensation, but shall be subject
to the following special rules:

                  (a) If the largest contribution on behalf of a key employee
         for such year, taking into account only Elective Contributions,
         Matching Contributions (if any), Discretionary Contributions and
         Qualified Nonelective Contributions, is equal to less than 3% of the
         key employee's Compensation, such lesser percentage shall be the
         minimum contribution percentage for Participants who are not key
         employees. This special rule shall not apply, however, if the Plan is
         required to be included in an aggregation group and enables a defined
         benefit plan to meet the requirements of Code section 401(a)(4) or 410.

                  (b) No minimum contribution will be required with respect to a
         Participant who is also covered by another top-heavy defined
         contribution plan of an Affiliated Employer which meets the vesting
         requirements of Code section 416(b) and under which the Participant
         receives the top-heavy minimum contribution.

                  (c) If a Participant is also covered by a top-heavy defined
         benefit plan of an Affiliated Employer, "5%" shall be substituted for
         "3%" above in determining the minimum contribution.

                  (d) The minimum contribution with respect to any Participant
         who is not a key employee for the particular year will be offset by any
         Discretionary Contributions and any Qualified Nonelective
         Contributions, but not any other type of contribution otherwise made
         for the Participant's benefit for such year. Notwithstanding the
         foregoing, for Plan Years beginning after December 31, 2001, the
         minimum contribution described above will be offset also by any
         Matching Contributions made for the Participant's benefit for such
         year.

                  (e) If additional minimum contributions are required under
         this Section, such contributions shall be credited to the Participant's
         Discretionary Contribution Account.

                  (f) A minimum contribution required under this Section shall
         be made even though, under other Plan provisions, the Participant would
         not otherwise be entitled to receive an allocation for the year because
         of (i) the Participant's failure to complete 1,000 hours of service (or
         any equivalent provided in the Plan), or (ii) the Participant's failure
         to make mandatory contributions or Elective Contributions to the Plan,
         or (iii) Compensation less than a stated amount.

         12.3. ADJUSTMENT TO LIMITATION ON BENEFITS. With respect to Plan Years
prior to January 1, 2001, for purposes of the Code section 415 limits, the
definitions of "defined contribution plan fraction" and "defined benefit plan
fraction" contained therein shall be modified, for any Plan Year which is a
top-heavy Plan Year, by substituting "1.0" for "1.25" in Code sections
415(e)(2)(B) and 415(e)(3)(B).

         12.4. DEFINITIONS. For purposes of these top-heavy provisions, the
following terms have the following meanings:

                  (a) "key employee" means a key employee described in Code
         section 416, and "non-key employee" means any employee who is not a key
         employee (including employees who are former key employees);

                  (b) "top-heavy plan year" means a Plan Year if any of the
         following conditions exist:

                           (i) the top-heavy ratio for the Plan exceeds 60
                  percent and the Plan is not part of any required aggregation
                  group or permissive aggregation group of plans;

                           (ii) this Plan is a part of a required aggregation
                  group of plans but not part of a permissive aggregation group
                  and the top-heavy ratio for the group of plans exceeds 60
                  percent; or

                           (iii) the Plan is part of a required aggregation
                  group and part of a permissive aggregation group of plans and
                  the top-heavy ratio for the permissive aggregation group
                  exceeds 60 percent.

                  (c) "top-heavy ratio":

                           (i) If the employer maintains one or more defined
                  contribution plans (including any Simplified Employee Pension
                  Plan) and the employer has not maintained any defined benefit
                  plan which during the 5-year period ending on the
                  determination date(s) has or has had accrued benefits, the
                  top-heavy ratio for the Plan alone or for the required or
                  permissive aggregation group as appropriate is a fraction, the
                  numerator of which is the sum of the account balances of all
                  key employees on the determination date(s) (including any part
                  of any account balance distributed in the 1-year period ending
                  on the determination date(s)), and the denominator of which is
                  the sum of all account balances (including any part of an
                  account balance distributed in the 1-year period ending on the
                  determination date(s) and in the case of a distribution made
                  for a reason other than separation from service, death or
                  disability, including any such amount distributed in the
                  5-year period ending in determination dates(s)), both computed
                  in accordance with Code section 416. Both the numerator and
                  the denominator of the top-heavy ratio are increased to
                  reflect any contribution not actually made as of the
                  determination date, but which is required to be taken into
                  account on that date under Code section 416.

                           (ii) If the employer maintains one or more defined
                  contribution plans (including any Simplified Employee Pension
                  Plan) and the employer maintains or has maintained one or more
                  defined benefit plans which during the 5-year period ending on
                  the determination date(s) has or has had any accrued benefits,
                  the top-heavy ratio for any required or permissive aggregation
                  group as appropriate is a fraction, the numerator of which is
                  the sum of the account balances under the aggregated defined
                  contribution plan or plans for all key employees, determined
                  in accordance with (i) above, and the present value of accrued
                  benefits under the aggregated defined benefit plan or plans
                  for all key employees as of the determination date(s), and the
                  denominator of which is the sum of the account balances under
                  the aggregated defined contribution plan or plans for all
                  participants, determined in accordance with (i) above, and the
                  present value of all accrued benefits under the defined
                  benefit plan or plans for all participants as of the
                  determination date(s), all determined in accordance with Code
                  section 416. The accrued benefits under a defined benefit plan
                  in both the numerator and denominator of the top-heavy ratio
                  are increased for any distribution of an accrued benefit made
                  in the 1-year period ending on the determination date.

                           (iii) For purposes of (i) and (ii) above, the value
                  of account balances and the present value of accrued benefits
                  will be determined as of the most recent valuation date that
                  falls within or ends with the 12-month period ending on the
                  determination date, except as provided in Code section 416 for
                  the first and second plan years of a defined benefit plan. The
                  account balances and accrued benefits of a participant (A) who
                  is not a key employee but who was a key employee in a prior
                  year, or (B) who has not been credited with at least one Hour
                  of Service with any employer maintaining the plan at any time
                  during the 1-year period ending on the determination date will
                  be disregarded. The calculation of the top-heavy ratio, and
                  the extent to which distributions, rollovers, and transfers
                  are taken into account will be made in accordance with Code
                  section 416. Deductible employee contributions will not be
                  taken into account for purposes of computing the top-heavy
                  ratio. When aggregating plans, the value of account balances
                  and accrued benefits will be calculated with reference to the
                  determination dates that fall within the same calendar year.

                           (iv) The accrued benefit of a Participant other than
                  a key employee shall be determined under (A) the method, if
                  any, that uniformly applies for accrual purposes under all
                  defined benefit plans maintained by the employer, or (B) if
                  there is no such method, as if such benefit accrued not more
                  rapidly than the slowest accrual rate permitted under the
                  fractional rule of Code section 411(b)(1)(C).

                  (d) The "permissive aggregation group" is the required
         aggregation group of plans plus any other plan or plan of the employer
         which, when considered as a group with the required aggregation group,
         would continue to satisfy the requirements of Code sections 401(a)(4)
         and 410.

<PAGE>

                  (e) The "required aggregation group" is (i) each qualified
         plan of the employer in which at least one key employee participates or
         participated at any time during the determination period (regardless of
         whether the plan has terminated), and (ii) any other qualified plan of
         the employer which enables a plan described in (i) to meet the
         requirements of Code sections 401(a)(4) and 410(b).

                  (f) For purposes of computing the top-heavy ratio, the
         "valuation date" shall be the last day of the applicable plan year.

                  (g) For purposes of establishing present value to compute the
         top-heavy ratio, any benefit shall be discounted only for mortality and
         interest based on the interest and mortality rates specified in the
         defined benefit plan(s), if applicable.

                  (h) The term "determination date" means, with respect to the
         initial plan year of a plan, the last day of such plan year and, with
         respect to any other plan year of a plan, the last day of the preceding
         plan year of such plan. The term "applicable determination date" means,
         with respect to the Plan, the determination date for the Plan Year of
         reference and, with respect to any other plan, the determination date
         for any plan year of such plan which falls within the same calendar
         year as the applicable determination date of the Plan.

                           ARTICLE 13. MISCELLANEOUS.

         13.1. EXCLUSIVE BENEFIT RULE. No part of the corpus or income of the
Trust allocable to the Plan will be used for or diverted to purposes other than
for the exclusive benefit of each Participant and Beneficiary, except as
otherwise provided under the provisions of the Plan relating to Qualified
Domestic Relations Orders, the payment of reasonable expenses of administering
the Plan, the return of contributions upon nondeductibility or mistake of fact,
or the failure of the Plan to qualify initially.

         13.2. LIMITATION OF RIGHTS. Neither the establishment of the Plan or
the Trust, nor any amendment thereof, nor the creation of any fund or account,
nor the payment of any benefits, will be construed as giving to any Participant
or other person any legal or equitable right against any Participating Employer
or Committee or Trustee, except as provided herein, and in no event will the
terms of employment or service of any Participant be modified or in any way be
affected hereby. It is a condition of the Plan, and each Participant expressly
agrees by his or her participation herein, that each Participant will look
solely to the assets held in the Trust for the payment of any benefit to which
he or she is entitled under the Plan.

         13.3. NONALIENABILITY OF BENEFITS. The benefits provided hereunder will
not be subject to the voluntary or involuntary alienation, assignment,
garnishment, attachment, execution or levy of any kind, and any attempt to cause
such benefits to be so subjected will not be recognized, except to such extent
as may be required by law, except that if the Committee receives any Qualified
Domestic Relations Order that requires the payment of benefits hereunder or the
segregation of any Account, such benefits shall be paid, and such Account
segregated, in accordance with the applicable requirements of such Order. In
addition, the Account balance may be pledged as security for a loan from the
Plan in accordance with the Plan's loan procedures.

         13.4. ADEQUACY OF DELIVERY. Any payment to be made under the Plan by
the Trustee may be made by the Trustee's check. Mailing to a person or persons
entitled to distributions hereunder at the addresses designated by the
Participating Employer or Committee shall be adequate delivery by the Trustee of
such distributions for all purposes. In the event the whereabouts of a person
entitled to benefits under the Plan cannot be determined after diligent search
by the Committee, the Committee may place the benefits in a federally insured,
interest-bearing bank account opened in the name of such person. Such action
shall constitute a full distribution of such benefits under the terms of the
Plan and Trust.

         13.5. RECLASSIFICATION OF EMPLOYMENT STATUS. Notwithstanding anything
herein to the contrary, an individual who is not characterized or treated as a
common law employee of a Participating Employer shall not be eligible to
participate in the Plan. However, in the event that such an individual is
reclassified or deemed to be reclassified as a common law employee of a
Participating Employer, the individual shall be eligible to participate in the
Plan as of the actual date of such reclassification (to the extent such
individual otherwise qualifies as an Eligible Employee hereunder). If the
effective date of any such reclassification is prior to the actual date of such
reclassification, in no event shall the reclassified individual be eligible to
participate in the Plan retroactively to the effective date of such
reclassification.

         13.6. VETERANS' REEMPLOYMENT AND BENEFITS RIGHTS. Effective December
12, 1994 and notwithstanding any provision of the Plan to the contrary,
contributions, benefits and service credit with respect to qualified military
service will be provided in accordance with Code section 414(u).

         13.7. GOVERNING LAW. The Plan and Trust will be construed, administered
and enforced according to the laws of Massachusetts to the extent such laws are
not preempted by ERISA.

         13.8. AUTHORITY TO CORRECT OPERATIONAL DEFECTS. The Committee will have
full discretionary power and authority to correct any "operational defect" of
the Plan in any manner or by any method it deems appropriate in its sole
discretion in order to cause the Plan (i) to operate in accordance with its
terms or (ii) to maintain its tax-qualified status under the Code. For purposes
of this Section, an "operational defect" is any operational or administrative
action (or inaction) in connection with the Plan which, in the judgement of the
Committee, fails to conform with the terms of the Plan or causes or could cause
the Plan to lose its tax-qualified status under the Code.

         13.9. ELECTRONIC FORMS. Notwithstanding any Plan provision to the
contrary, to the extent the Committee allows any form or document under the Plan
to be provided, completed or changed by means of telephone, computer or other
paperless media, a paper document shall not be required for such form or
document to be effective under the Plan.

organization; provided, that the term "Affiliated Employer" shall not include
any corporation or unincorporated trade or business prior to the date on which
such corporation, trade or business satisfies the affiliation or control tests
of, (b), (c), (d) or (e) above. In identifying any "Affiliated Employers" for
purposes of the Code section 415 limits, the definitions in Code sections 414(b)
and (c) shall be modified as provided in Code section 415(h).

         14.3. "BENEFICIARY" means any person entitled to receive benefits under
the Plan upon the death of a Participant.

                  (a) for purposes of determining the Code section 415 limits,
         the amount of any minimum contribution under the special top-heavy
         provisions, and determining the status of an individual as a "highly
         compensated employee" or a "key employee", the Participant's wages as
         defined in Code section 3401(a) for purposes of income tax withholding
         at the source, but (i) determined without regard to any rules that
         limit the remuneration included in wages based on the nature or
         location of the employment or the services performed, and

                                     - 43 -

         (ii) increased by any such amounts that would have been received by the
         individual from the Employer but for an election under Code section
         125, 132(f)(4), 401(k), 402(h) or 403(b);

                  (b) for purposes of determining the Code section 415 limits
         and the amount of any minimum contribution under the special top-heavy
         provisions, the Participant's wages as defined in Code section 3401(a)
         for purposes of income tax withholding at the source but determined
         without regard to any rules that limit the remuneration included in
         wages based on the nature or location of the employment or the services
         performed;

                  (c) for purposes of the limits under Sections 11.4 and 11.5,
         "compensation" as defined under Code section 414(s) and the Treasury
         regulations thereunder; and

                  (d) for all other purposes under the Plan, the same as in (a)
         above, reduced by all of the following items (even if includable in
         gross income): cost-of-living adjustments, reimbursements or other
         expense allowances, pay in lieu of vacation upon termination of
         employment, bonuses, deferred compensation, payments under the
         Supplemental Severance Plan, and moving expenses, provided however that
         any elective contributions made by the Participating Employer that are
         not includible in gross income by reason of Code section 125 or
         402(e)(3) shall in all cases be includible as "Compensation" for
         purposes of this paragraph (d). Notwithstanding the foregoing, for
         purposes of allocating Discretionary Contributions for a Plan Year,
         commissions paid to any field sales commissioned Employee who is a
         Highly Compensated Employee for such Plan Year shall be taken into
         consideration only to the extent of the lesser of (i) fifty percent of
         the amount of the commissions so paid, or (ii) the amount, not in
         excess of the commissions so paid, which when added to all other
         amounts paid such Employee and qualifying as Compensation results in an
         aggregate amount of Compensation of $85,000 or less.

                  (e) Compensation shall include only that compensation which is
         actually paid to the Participant during the applicable Plan Year. For
         all purposes under the Plan, Compensation for any individual will be
         limited for any Plan Year as provided under Code section 401(a)(17)
         (which for the 2001 Plan Year is $170,000 and for the 2002 Plan Year is
         $200,000). If the period for determining Compensation used in
         calculating a Participant's allocation for a determination period is
         shorter than 12 months, the annual Compensation limit shall be an
         amount equal to the otherwise applicable limit multiplied by a
         fraction, the numerator of which is the number of months in the period,
         and the denominator of which is 12.

         14.9. "DISABILITY" means an injury or sickness which makes a
Participant unable to perform each of the "essential functions" (as defined in
the Boston Scientific Long Term Disability Plan) of any "gainful occupation" (as
defined in the Boston Scientific Long Term Disability Plan) for which the
Participant is reasonably fitted by training, education or experience.

         14.10. "DISCRETIONARY CONTRIBUTION" means a contribution made for the
benefit of a Participant by a Participating Employer in the discretion of the
Board of Directors.

      Special Contribution for Certain Former Employees of Cardiac Pathways

         Pursuant to Section 3.8, the Participating Employers will make, in
2002, a special contribution on behalf of each Participant who (i) formerly
participated in the Cardiac Pathways Corporation 401(k) Plan (the "Cardiac
Plan"), (ii) earned in the aggregate less than $60,000 in 2001 from Boston
Scientific Corporation and Cardiac Pathways Corporation, and (iii) was actively
employed by Boston Scientific Corporation as of the last day of the Plan Year.
Such contribution for each eligible Participant shall equal 35% of such
Participant's "projected elective deferral amount". For purposes of this
paragraph, "projected elective deferral amount" means the amount that the
Participant would have deferred under the Cardiac Plan from August 8, 2001
through December 31, 2001 if the Cardiac Plan had not been terminated and if the
Participant's elective deferral election under the Cardiac Plan as of August 7,
2001 had remained the same for the remainder of the year.

                                 FIRST AMENDMENT

         Pursuant to Section 10.1 of the Boston Scientific Corporation 401(k)
Retirement Savings Plan as amended and restated effective January 1, 2001 (the
"Plan"), Boston Scientific Corporation hereby amends the Plan, effective January
1, 2003, as follows:

         1. Section 3.1 is amended by deleting the last sentence thereof and by
replacing it with the following:

         "Elective Contributions for any pay period in a Plan Year may not be
         less than 1 percent of the Participant's Compensation for such pay
         period and the maximum amount of Elective Contributions for any pay
         period shall be the least of:

                  (a) 25 percent of the Participant's Compensation for such pay
         period;

                  (b) the maximum amount permitted under Article 11; and

                  (c) any further limit placed on Highly Compensated Employees
         by the Committee in its discretion in anticipation of satisfying the
         actual deferral percentage or actual contribution percentage limits
         described in Article 11.

         In addition, effective January 1, 2003, Participants who have attained
         age 50 before the close of a Plan Year shall be eligible to have
         catch-up Elective Contributions made on their behalf for the Plan Year
         in accordance with, and subject to, the limitations of Code section
         414(v). Such catch-up Elective Contributions shall not be taken into
         account for purposes of compliance by the Plan with the required
         limitations of Code sections 402(g) and 415. The Participating
         Employers will not make Matching Contributions on account of catch-up
         Elective Contributions."

         2. Section 3.3 (a) is amended by deleting the last sentence thereof and
by replacing it with the following:

         "The amount of Matching Contributions made by a Participating Employer
         for the period shall be equal to (i) 100% of the Elective Contributions
         (excluding catch-up Elective Contributions) made on behalf of the
         Participant for the period which do not exceed 2% of the Participant's
         Compensation for such period, plus (ii) 50% of the Elective
         Contributions (excluding catch-up Elective Contributions) made on
         behalf of the Participant for the period which exceed 2% but do not
         exceed 4% of the Participant's Compensation for such period."

         3. Section 4.3(a) is amended by adding the following to the end
thereof:

         "Notwithstanding the foregoing, all investments under the Plan are
         subject to the rules and limitations contained in the prospectus or
         other documents that describe the investment."

         4. Section 5.5 is amended by deleting paragraph (c) and replacing it
with the following:

         "(c) If a Participant forfeits any part of his or her Accounts under
         paragraph (a) above, the amount of the forfeiture will be applied,
         first, toward any restoration of any amount previously forfeited as
         required under paragraph (a) above, and then, toward either (i) the
         payment of reasonable expenses of administering the Plan, or (ii) the
         Matching Contributions required to be made to the Plan under Section
         3.3, as determined by the Committee."

         5. Section 6.6 is amended by deleting the first sentence in the last
paragraph and replacing it with the following:

         "For purposes of this Section, a Participant's Accounts will be
         considered to be valued in excess of $5,000 if the value of his or her
         Accounts (excluding any Rollover Contributions and any earnings
         thereon) exceeds such amount at the time of the distribution in
         question."

         6. Section 6.6 is further amended by adding the following to the end
thereof:

         "Notwithstanding the foregoing, periodically the Committee will
         distribute terminated Participants' Accounts that no longer have a
         value in excess of $5,000."

         7. Section 6.8 is amended by adding the following to the end thereof:

         "With respect to distributions under the Plan made for calendar years
         beginning on or after January 1, 2003, the Plan will apply the minimum
         distribution requirements of Code section 401(a)(9) in accordance with
         the Final and Temporary Regulations that were issued on April 17,
         2002."

         8. Section 8.2 is amended by deleting the first sentence in the last
paragraph and replacing it with the following:

         "A Participant's Accounts will be considered to be valued in excess of
         $5,000 if the value of such Accounts (excluding Rollover Contributions
         and any earnings thereon) exceeds such amount at the time of the
         distribution in question."

         9. Section 8.2 is further amended by adding the following to the end
thereof:

         "Notwithstanding the foregoing, periodically the Committee will
         distribute terminated Participants' Accounts that no longer have a
         value in excess of $5,000."

                                      -2-

<PAGE>

         10. Article 9 is amended by adding a new Section 9.8 to read as
follows:

         "9.8 Expenses of Plan. The Committee may direct the Trustee to pay from
         the Trust any or all expenses of administering the Plan, to the extent
         such expenses are reasonable. The Committee will determine what
         constitutes a reasonable expense of administering the Plan, and whether
         such expenses shall be paid from the Trust. Any such expenses not paid
         out of the Trust shall be paid by the Company; provided, however, that
         to the extent permitted by ERISA, the Committee may direct the Trustee
         to reimburse the Company out of the Trust for a reasonable expense of
         administering the Plan which is paid by the Company prior to a
         determination with respect to such expense."

         IN WITNESS WHEREOF, Boston Scientific Corporation has caused this
amendment to be executed in its name and on its behalf this ________ day of
____________________, 2002.

outstanding at the same time.

      2.3 REQUESTS FOR BORROWINGS; CONVERSION OF BORROWINGS.

            (a) To request a Revolving Borrowing, the Borrower shall notify the
Lender of such request by telephone (i) in the case of a Eurodollar Borrowing,
not later than 10:00 a.m., New York City time, not less than two (2) nor more
than five (5) Business Days before the date of the proposed Borrowing or (ii) in
the case of a Base Rate Borrowing not later than 11:00 a.m., Boston,
Massachusetts time on the date of the proposed Borrowing. Each such telephonic
Borrowing Request shall be irrevocable and shall be confirmed promptly by hand
delivery or telecopy to the Lender of a written Borrowing Request in a form
approved by the Lender and signed by the Borrower.

            (b) Each such telephonic and written Borrowing Request shall specify
the following information in compliance with Section 2.2:

            (i) the aggregate amount of such Borrowing;

            (ii) the effective date of such Borrowing, which shall be a Business
      Day;

            (iii) whether such Borrowing is to be a Base Rate Borrowing or a
      Eurodollar Borrowing;

            (iv) in the case of a Eurodollar Borrowing, the initial Interest
      Period to be applicable thereto, which shall be a period contemplated by
      the definition of the term "Interest Period"; and

            (v) the location and number of the Borrower's account to which funds
      are to be disbursed, which shall comply with the requirements of Section

            (c) If no election as to the Type of Borrowing is specified, then
the requested Borrowing shall be a Base Rate Borrowing. If no Interest Period is
specified with respect to any requested Eurodollar Borrowing, then the Borrower
shall be deemed to have selected an Interest Period of one month's duration.

            (d) Each Borrowing initially shall be of the Type specified in the
applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall
have an initial Interest Period as specified in such Borrowing Request.
Thereafter, the Borrower may elect to convert such Borrowing to a different Type
or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may
elect

                                      -21-
<PAGE>

Interest Periods therefor, all as provided in this Section 2.3. The Borrower may
elect different options for continuations and conversions with respect to
different portions of the affected Borrowing, in which case the Loans comprising
each such portion shall be considered a separate Borrowing. Each such portion
shall be in an aggregate principal amount contemplated by Section 2.2(b).

            (e) If the Borrower desires to convert any Borrowing to a different
Type or to continue such Borrowing for an additional Interest Period, the
Borrower shall notify the Lender of such election by telephone by the time that
a Borrowing Request would be required under this Section 2.3 if the Borrower
were requesting a new Borrowing of the Type resulting from such election to be
made on the effective date of such election. Each such telephonic Interest
Election Request shall be irrevocable and shall be confirmed promptly by hand
delivery or telecopy to the Lender of a written Borrowing Request in a form

prior to the end of the Interest Period applicable thereto, then, unless such
Borrowing is repaid as provided herein, at the end of such Interest Period such
Borrowing shall be converted to a Base Rate Borrowing. Notwithstanding any
contrary provision hereof, if a Default or Event of Default has occurred and is
continuing and the Lender so notifies the Borrower, then, so long as a Default
or Event of Default is continuing (i) no outstanding Borrowing may be converted
to or continued as a Eurodollar Borrowing and (ii) unless repaid, each
Eurodollar Borrowing shall be converted to a Base Rate Borrowing at the end of
the Interest Period applicable thereto.

may request that the Lender issue Letters of Credit for the Borrower's own
account in a form reasonably acceptable to the Lender at any time and from time
to time during the Revolving Credit Availability Period. There shall be no
sublimit specially applicable to Letters of Credit, and therefore Letters of
Credit issued hereunder shall constitute utilization of, and shall reduce
availability under, the Revolving Credit Commitment.

CONDITIONS. To request the issuance of a Letter of Credit (or the amendment,

Business Days in advance of the requested date of issuance, amendment, renewal
or extension) a letter of credit application on the Lender's standard form. A
Letter of Credit shall be issued, amended, renewed or extended only if (and upon
issuance, amendment, renewal or extension of each Letter of Credit the Borrower
shall be deemed to represent and warrant that), after giving effect to such
issuance, amendment, renewal or extension the total Revolving Credit Exposure
shall not exceed the lesser of (i) the Revolving Credit Commitment at such time,
and (ii) the Borrowing Base at such time.

            (c) EXPIRATION DATE. Each Letter of Credit shall expire (without
giving effect to any extension thereof by reason of an interruption of business)
at or prior to the close of business on the earlier of (i) the date 365 days, in
the case of standby Letters of Credit, or 180 days, in the case of documentary
Letters of Credit after the date of the issuance of such Letter of Credit (or,
in the case of any renewal or extension thereof, 365 days or 180 days, as

Letter of Credit may provide for automatic extensions thereof to a date not
later than 365 days beyond its current expiration date, and (ii) the date that
is five (5) Business Days prior to the Revolving Credit Maturity Date. No Letter
of Credit may be extended beyond the date that is five (5) Business Days prior

            (d) REIMBURSEMENT. If the Lender shall make any LC Disbursement in
respect of a Letter of Credit, the Borrower shall reimburse the Lender in
respect of such LC Disbursement by paying to the Lender an amount (each, a
"Reimbursement Obligation") equal to such LC Disbursement not later than (i)
3:00 p.m., Boston, Massachusetts time, on the Business Day that the Borrower
receives notice of such LC Disbursement, if such notice is received prior to
11:00 a.m., Boston, Massachusetts time, or (ii) the Business Day immediately
following the day that the Borrower receives such notice, if such notice is not
received prior to such time; PROVIDED that, subject to the conditions to
borrowing set forth herein (other than the requirements of Section 2.3 relating
to notice and the submission of Borrowing Requests), unless the Borrower
otherwise notifies the Lender prior to 3:00 p.m. Boston time on the date any
such Reimbursement Obligation is due, payment of such Reimbursement Obligation
shall be made through the automatic funding of a Base Rate Borrowing in an
amount equal to the amount of such Reimbursement Obligation, and the Borrower
hereby irrevocably authorizes and directs the Lender to take such actions as may
necessary to effectuate such automatic funding of such Base Rate Borrowing. To
the extent that any such Reimbursement Obligation is paid through the automatic
funding of a Base Rate Borrowing, the Borrower's obligation to make such payment
shall be discharged and replaced by the resulting Base Rate Borrowing.

            (e) OBLIGATIONS ABSOLUTE. The Borrower's obligation to reimburse LC
Disbursements as provided in paragraph (d) of this Section 2.4 shall be
absolute, unconditional and irrevocable, and shall be performed strictly in
accordance with the terms of this Agreement irrespective of the following: (i)
any lack of validity or enforceability of any Letter of Credit, or any term or
provision therein, (ii) any draft or other document presented under a Letter of
Credit proving to be forged, fraudulent or invalid in any respect or any
statement therein being untrue or inaccurate in any respect, (iii) payment by
the Lender to the beneficiary under a Letter of Credit against presentation of a
draft or other document that does not comply strictly with the terms of such
Letter of Credit or (iv) any other event or circumstance whatsoever (other than
gross negligence or willful misconduct of the Lender), whether or not similar to
any of the foregoing, that might, but for the provisions of this Section 2.4,
constitute a legal or equitable discharge of the Borrower's obligations
hereunder.

            (f) INTERIM INTEREST. If the Lender shall make any LC Disbursement
in respect of any Letter of Credit, then, unless the Borrower shall reimburse
such LC Disbursement in full on the date such LC Disbursement is made, the
unpaid amount thereof shall bear interest, for each day from and including the
date such LC Disbursement is made to but excluding the date that the Borrower
reimburses such LC Disbursement, at the rate per annum then applicable to
Revolving Base Rate Loans; PROVIDED that, if the Borrower fails to reimburse
such LC Disbursement when due pursuant to paragraph (d) of this Section 2.4,
then interest calculated in accordance with Section 2.11(c) shall accrue on the
unpaid amount thereof.

            (g) CASH COLLATERALIZATION. If either (i) an Event of Default shall
occur and be continuing and the Borrower receives notice from the Lender
demanding the deposit of cash collateral pursuant to this paragraph, or (ii) the
Borrower shall be required to provide cover for the Total LC Exposure pursuant
to Sections 2.8(a) or 2.9(b), the Borrower shall immediately deposit with the
Lender an amount in cash equal to, in the case of an Event of Default, the Total
LC Exposure as of the date of such notice plus any accrued and unpaid interest
thereon and, in the case of cover pursuant to Sections 2.8(a) or 2.9(b), the
amount required under Sections 2.8(a) or 2.9(b), as the case may be; PROVIDED
that the obligation to deposit such cash collateral shall become effective
immediately, and such deposit shall become immediately due and payable, without
demand or other notice of any kind, upon the occurrence of any Event of Default
with respect to the Borrower described in Sections 9.1 (g), (h) or (i). Such
deposit shall be held by the Lender as collateral in the first instance for the
Total LC Exposure under this Agreement and thereafter for the payment of any
other obligations of the Borrower hereunder.

            (a) Unless previously terminated, (i) the Revolving Credit
Commitment shall terminate at the close of business on the Revolving Credit

Business Day after the date on which the Effective Time occurs.

reduce, the Revolving Credit Commitment; PROVIDED that (i) each reduction of the
Revolving Credit Commitment shall be in an amount that is at least equal to
$100,000 or any greater multiple of $10,000, and (ii) the Borrower shall not
terminate or reduce the Revolving Credit Commitment if, after giving effect to

would exceed the total Revolving Credit Commitment.

            (c) The Borrower shall notify the Lender of any election to
terminate or reduce the Revolving Credit Commitment at least five (5) Business
Days prior to the effective date of such termination or reduction, specifying
such election and the effective date thereof. Each notice delivered by the
Borrower with respect to any termination or reduction of the Revolving Credit
Commitment shall be irrevocable; PROVIDED that a notice of termination of the
Commitments delivered by the Borrower may state that such notice is conditioned
upon the effectiveness of other credit facilities, in which case such notice may
be revoked by the Borrower (by notice to the Lender on or prior to the specified
effective date) if such condition is not satisfied; PROVIDED, FURTHER, that
Section 2.14 shall be applicable notwithstanding that such revocation is
permitted. Any termination or reduction of the Revolving Credit Commitment shall

Massachusetts as shall be notified to the Borrower from time to time. If any
payment hereunder shall be due on a day that is not a Business Day, the date for

obligations recorded therein; PROVIDED that the failure of the Lender to

obligation of the Borrower to repay the Loans in accordance with the terms of
this Agreement. The Lender agrees to provide to the Borrower, from time to time
upon reasonable prior request by the Borrower, a statement of activity in any
such account maintained by the Lender.

            (a) OPTIONAL PREPAYMENTS. Subject to the payment of any amounts due
under Section 2.14, the notice requirements of Section 2.9(e) and the
requirement that any Eurodollar Loan to be repaid is to be repaid in full, the
Borrower shall have the right at any time and from time to time to prepay any
Eurodollar Revolving Loan or repay the Term Loan; provided that each such
prepayment or repayment shall be in an amount that is at least equal to $100,000
or any greater multiple of $10,000. The Borrower shall have the right at any
time and from time to time to prepay any Base Rate Revolving Loan in whole or in
part. Each voluntary prepayment of the Term Loan shall be applied against unpaid
principal installments thereof in inverse order of maturity.

            (b) MANDATORY PREPAYMENTS. The Borrower shall be obligated to, and
shall, make prepayments of the Loans hereunder (and reduce the Revolving Credit
Commitment hereunder) as follows:

            (i) INCURRENCE OF DEBT. Without limiting the obligation of the
      Borrower to obtain the consent of the Lender to any incurrence of
      Indebtedness not otherwise permitted hereunder, the Borrower agrees, on or
      prior to the closing of any incurrence of Indebtedness (other than
      Indebtedness permitted pursuant to Section 8.1) by any Credit Party, to
      deliver to the

                                      -25-
<PAGE>

      Lender a statement certified by a Designated Financial Officer of the
      Borrower, in form and detail reasonably satisfactory to the Lender, of the
      estimated amount of the Net Cash Payments from such incurrence of
      Indebtedness that will (on the date of such incurrence of Indebtedness) be
      received by any Credit Party and the Borrower will prepay the Loans
      hereunder (and reduce the Revolving Credit Commitment hereunder) upon the
      date of such incurrence of Indebtedness, in an aggregate amount equal to
      100% of the estimated amount of the Net Cash Payments from such incurrence
      of Indebtedness received by any Credit Party, such prepayment and
      reduction to be effected in each case in the manner and to the extent
      specified in paragraph (c) of this Section 2.9;

            (ii) OFFERING OF SECURITIES. The Borrower agrees, on or prior to the
      closing of any offering of equity securities by any Credit Party, to
      deliver to the Lender a statement certified by a Financial Officer of the
      Borrower, in form and detail reasonably satisfactory to the Lender, of the
      estimated amount of the Net Cash Payments from such offering of securities
      that will (on the date of such offering of securities) be received by any
      Credit Party and the Borrower will prepay the Loans hereunder (and, if an
      Event of Default shall have occurred and be continuing, reduce the
      Revolving Credit Commitment hereunder) upon the date of such sale or
      offering of securities, in an aggregate amount equal to 100% of the amount
      of Net Cash Payments from such offering of securities received by any
      Credit Party, such prepayment to be effected in each case in the manner
      and to the extent specified in paragraph (c) of this Section 2.9;

            (iii) SALE OF ASSETS. Without limiting the obligation of the
      Borrower to obtain the consent of the Lender to any Disposition not
      otherwise permitted hereunder, the Borrower agrees, on or prior to the
      occurrence of any Disposition by any Credit Party, to deliver to the
      Lender a statement certified by a Designated Financial Officer of the
      Borrower, in form and detail reasonably satisfactory to the Lender, of the
      estimated amount of the Net Cash Payments of such Disposition that will
      (on the date of such Disposition) be received by any Credit Party in cash,
      indicating on such certificate whether the Credit Parties intend to
      reinvest such Net Cash Payments or the Borrower will be prepaying the
      Loans, as hereinafter provided, and, the Borrower will be obligated to
      either (A) cause the Credit Parties to reinvest such Net Cash Payments by
      180 days after receipt pursuant to one or more Capital Expenditures
      permitted hereunder (the "REINVESTMENT DATE") or (B) prepay the Loans
      hereunder (and reduce the Revolving Credit Commitment hereunder), in an
      aggregate amount equal to 100% of such estimated amount of such Net Cash
      Payments, to the extent received by any Credit Party in cash on the date
      of such Disposition, or, if not reinvested on or prior to the applicable
      Reinvestment Date, on the first Business Day following such Reinvestment
      Date, such prepayment to be effected in each case in the manner and to the
      extent specified in paragraph (c) of this Section 2.9. Notwithstanding the
      foregoing, the Borrower shall not be required to make any prepayment of
      Loans or reinvestment of Net Cash Payments under this Section 2.9(b)(iii)
      with respect to the first $500,000 of aggregate Net Cash Payments received
      by the Credit Parties from Dispositions after the Effective Time; and

            (iv) PROCEEDS OF CASUALTY EVENTS. Upon the date 181 days following
      the receipt by any Credit Party of the proceeds of insurance, condemnation
      award or other compensation in respect of any Casualty Event affecting any
      property of any Credit Party (or upon such earlier date as such Credit
      Party shall have determined not to repair or replace the property affected
      by such Casualty Event), the Borrower shall prepay the Loans (and reduce
      the Revolving Credit Commitment hereunder), in an aggregate amount equal
      to 100% of the Net Cash Payments from such Casualty Event not theretofore
      applied or committed to be applied to the repair or replacement of such
      property as provided in this clause (iv), such prepayment to be effected
      in each case in the manner and to the extent specified in paragraph (c) of
      this Section 2.9 (it being understood that if Net Cash Payments committed
      to be applied are not in fact applied

                                      -26-
<PAGE>

      within 180 days after receipt thereof, then such Net Cash Payments shall
      be applied to the prepayment of the Loans (and the reduction of the
      Revolving Credit Commitment)) as provided in this clause (iv) at the
      expiration of such 180 day period), such repayment and reduction to be
      effected in each case in the manner and to the extent specified in
      paragraph (c) of this Section 2.9.

            (c) APPLICATION. In the event of any mandatory prepayment of Loans
pursuant to subsection (b) of this Section, the proceeds shall be applied as
follows:

            (i) first, to the extent that Revolving Credit Exposure shall at
      such time exceed the lesser of (i) the Revolving Credit Commitment at such
      time and (ii) the Borrowing Base at such time, such prepayment shall be
      applied to the repayment of Revolving Loans;

            (ii) second, if such prepayment is made at a time when the Term
      Loans remain outstanding, such prepayment shall be applied to the
      repayment of the unpaid principal installments of the Term Loans in
      inverse order of maturity;

            (iii) third, if such prepayment is made at a time after the Term
      Loans have been repaid in full, the amount of any mandatory prepayment
      shall be applied to the repayment of the outstanding Revolving Loans (and
      thereafter to provide cover for LC Exposure) and to the corresponding
      reduction in the Revolving Credit Commitment.

            (d) SPECIAL PREPAYMENT OF TERM LOAN. If at any time the aggregate
outstanding amount of the Term Loan exceeds seventy five percent (75%) of the
appraised value (as set forth in any current appraisal which may be obtained by
the Borrower or the Lender) of the Mortgaged Properties, the Borrower shall
prepay the Term Loan in an amount equal to such excess. Mandatory prepayments
pursuant to this clause (d) shall be applied to reduce outstandings under the
Term Loan, in inverse order of maturity.

            (e) NOTIFICATION OF PREPAYMENTS. The Borrower shall notify the
Lender by telephone (confirmed by telecopy) of any repayment of a Eurodollar
Revolving Loan or a prepayment of the Term Loan hereunder not later than 10:00
a.m., Boston, Massachusetts time at least five (5) Business Days before the date
of such repayment or prepayment. Each such notice shall be irrevocable and shall
specify the repayment/prepayment date and the principal amount of the Loans to
be repaid/prepaid.

            (f) PREPAYMENTS ACCOMPANIED BY INTEREST. Prepayments shall be
accompanied by accrued interest to the extent required by Section 2.11(d).

      2.10 FEES.

            (a) ORIGINATION FEE. The Borrower shall pay to the Lender on the
Closing Date an origination fee in an amount separately agreed in writing
between the Borrower and the Lender.

            (b) COMMITMENT FEE. The Borrower shall pay to the Lender a
commitment fee, which shall accrue at a rate of .375% per annum on the daily
average unused amount of the Revolving Credit Commitment during the period from
and including the date on which the Effective Time shall occur to but excluding
the date on which the Revolving Credit Commitment terminates. Accrued commitment
fees shall be payable quarterly in arrears and on the date on which the
Revolving Credit Commitment terminates. All commitment fees shall be computed on
the basis of a year of 360 days and shall be payable for the actual number of
days elapsed (including the first day but excluding the last day).

                                      -27-
<PAGE>

            (c) LETTER OF CREDIT FEES. The Borrower shall pay to the Lender with
respect to any Letter of Credit issued hereunder the following fees:

            (i) a per annum letter of credit fee equal to 1.00% multiplied by
      the aggregate face amount of such Letter of Credit, payable in advance
      upon issuance of the applicable Letter of Credit and upon each anniversary
      of the issuance of such Letter of Credit, until the expiration or
      termination of such Letter of Credit; and

            (ii) the Lender's standard fees with respect to the amendment,
      renewal or extension of any Letter of Credit or processing of drawings
      thereunder, payable upon such amendment, renewal, extension or processing.

            (d) PAYMENT OF FEES. All fees payable hereunder shall be paid on the
dates due, in immediately available funds. Fees paid shall not be refundable
under any circumstances, absent manifest error in the determination thereof.

      2.11 INTEREST.

            (a) The Loans comprising each Base Rate Borrowing shall bear
interest at a rate per annum equal to the Adjusted Base Rate plus the Applicable
Margin.

            (b) The Loans comprising each Eurodollar Borrowing shall bear
interest at a rate per annum equal to the Adjusted LIBO Rate for the Interest
Period in effect for such Borrowing plus the Applicable Margin.

            (c) Notwithstanding the foregoing, (i) all amounts that are not paid
when due shall automatically bear interest until paid in full at the
Post-Default Rate, (ii) during the period when any Event of Default of the type
described in clauses (g), (h) or (i) of Section 9.1 shall have occurred and be
continuing, the principal of all Loans hereunder shall automatically bear
interest, after as well as before judgment, at the Post-Default Rate, (iii) if
there shall occur and be continuing any Event of Default (other than an Event of
Default of the type described in clauses (g), (h) or (i) of Section 9.1), then,
following written notice delivered to the Borrower from the Lender, the
principal of all Loans hereunder shall bear interest, after as well as before
judgment, at the Post-Default Rate during the period beginning on the date such
Event of Default first occurred and ending on the date such Event of Default is
cured or waived.

            (d) Accrued interest on each Loan shall be payable in arrears on
each Interest Payment Date for such Loan; PROVIDED that (i) interest accrued at
the Post-Default Rate shall be payable on demand, (ii) in the event of any
repayment or prepayment of any Eurodollar Loan (or the repayment or prepayment
in full of the Term Loans), accrued interest on the principal amount repaid or
prepaid shall be payable on the date of such repayment or prepayment, (iii) in
the event of any conversion of any Eurodollar Loan prior to the end of the
current Interest Period therefor, accrued interest on such Loan shall be payable
on the effective date of such conversion, (iv) all accrued interest on Revolving
Loans shall be payable upon expiration of the Revolving Credit Availability
Period, and (v) all accrued interest on the Term Loan not previously repaid
shall be payable on the Term Loan Maturity Date.

            (e) All interest hereunder shall be computed on the basis of a year
of 360 days, except that interest computed by reference to the Adjusted Base
Rate at times when the Adjusted Base Rate is based on the Prime Rate shall be
computed on the basis of a year of 365 days (or 366 days in a leap year), and in
each case shall be payable for the actual number of days elapsed (including the
first day

                                      -28-
<PAGE>

 but excluding the last day). The applicable Adjusted Base Rate,
Adjusted LIBO Rate or LIBO Rate shall be determined by the Lender, and such
determination shall be conclusive absent manifest error.

      2.12 ALTERNATE RATE OF INTEREST; ILLEGALITY.

            (a) If the Lender shall have determined (which determination shall
be conclusive absent manifest error) that (a) US dollar deposits in the relevant
amount and for the relevant Interest Period are not available to the Lender in
the London interbank market; (b) by reason of circumstances affecting the Lender
in the London interbank market, adequate means do not exist for ascertaining the
Adjusted LIBO Rate or the LIBO Rate applicable hereunder to Eurodollar Loans in
the relevant amount and for the relevant Interest Period, or (c) the Adjusted
LIBO Rate or the LIBO Rate no longer adequately reflect the Lender's cost of
funding Eurodollar Loans in the relevant amount and for the relevant Interest
Period; then, upon notice from the Lender to the Borrower, the obligations of
the Lender under this Agreement to make or continue any Loans as, or to convert
any Loans into, Eurodollar Loans in the relevant amount and for the relevant
Interest Period (each such Loan, an "UNAVAILABLE EURODOLLAR LOAN") shall
forthwith be suspended until the Bank shall notify the Borrower that the
circumstances causing such suspension no longer exist, and (i) any Unavailable
Eurodollar Loan then being requested shall be made as a Base Rate Loan unless
the Borrower shall notify the Lender no later than 10:00 a.m. New York City time
two (2) Business Days prior to the date of the proposed Borrowing that its
request for such Borrowing shall be cancelled or made as a Eurodollar Loan which
is not an Unavailable Eurodollar Loan (an "AVAILABLE EURODOLLAR LOAN"), in which
case, such request shall be cancelled or made as such Available Eurodollar Loan;
(ii) any Base Rate Loan or Eurodollar Loan which was to have been converted into
an Unavailable Eurodollar Loan shall be continued as or converted into a Base
Rate Loan unless the Borrower shall notify the Lender no later than 10:00 a.m.
New York City time two (2) Business Days prior to the date of the proposed
conversion that such Loan shall be maintained as or converted into an Available
Eurodollar Loan, in which case such Loan shall be maintained as or converted
into such Available Eurodollar Loan; and (iii) any outstanding Unavailable
Eurodollar Loan shall be converted into a Base Rate Loan unless the Borrower
shall notify the Lender no later than 10:00 a.m. New York City time two (2)
Business Days prior to the last Business Day of the then current Interest Period
applicable to such Unavailable Eurodollar Loan that such Loan shall be converted
into an Available Eurodollar Loan on the last Business Day of the then current
Interest Period for such Unavailable Eurodollar Loan, in which case such Loan
shall be converted into such Available Eurodollar Loan. At the time of any
request for an Available Eurodollar Loan pursuant to this Section 2.13(a), the
Borrower shall submit a Borrowing Request in respect of such Available
Eurodollar Loan to the Lender.

            (b) If the Lender shall have reasonably determined (which
determination shall, upon notice thereof to the Borrower be conclusive and
binding upon the Borrower) that any Change in Law makes it unlawful for the
Lender to make, continue or maintain any Eurodollar Loan as, or to convert any
Loan into, a Eurodollar Loan of a certain amount or duration (each such Loan, an
"UNPERMITTED EURODOLLAR LOAN"), the obligations of the Lender to make, continue,
maintain or convert into any such Unpermitted Eurodollar Loans shall, upon such
determination, forthwith be suspended until the Lender shall notify the Borrower
that the circumstances causing such suspension no longer exist, and any
Unpermitted Eurodollar Loan then being requested shall be made as a Base Rate
Loan unless the Borrower shall notify the Lender no later than 10:00 a.m. New
York City time two (2) Business Days prior to the date of the proposed Borrowing
that its request for such Borrowing shall be cancelled or made as a Eurodollar
Loan which is not an Unpermitted Eurodollar Loan (each such Loan, a "PERMITTED
EURODOLLAR LOAN"), in which case, such request shall be cancelled or made as
such Permitted Eurodollar Loan; (ii) any Base Rate Loan or Eurodollar Loan which
was to have been converted into an Unpermitted Eurodollar Loan shall be
continued as or converted into a Base Rate Loan unless the Borrower shall notify
the Lender no later than 10:00 a.m. New York City time two (2) Business Days
prior to the date of the proposed conversion that such Loan shall be maintained
as or converted into a Permitted Eurodollar

                                      -29-
<PAGE>

Loan, in which case such Loan shall be maintained as or converted into such
Permitted Eurodollar Loan; and (iii) any outstanding Unpermitted Eurodollar Loan
shall automatically convert into a Base Rate Loan upon the earlier of (x) the
end of the then current Interest Period with respect thereto, unless the
Borrower shall notify the Lender no later than 10:00 a.m. New York City time two
(2) Business Days prior to the last Business Day of the then current Interest
Period applicable to such Unpermitted Eurodollar Loan that such Loan shall be
converted into a Permitted Eurodollar Loan on the last Business Day of the then
current Interest Period for such Unpermitted Eurodollar Loan, in which case such
Unpermitted Eurodollar Loan shall convert to such Permitted Eurodollar Loan, or
(y) such time as required by such Change in Law. At the time of any request for
a Permitted Eurodollar Loan pursuant to this Section 2.13(b), the Borrower shall
submit a Borrowing Request in respect of such Permitted Eurodollar Loan to the
Lender.

      2.13 INCREASED COSTS.

            (a) If on or after the date hereof any Change in Law shall impose,
modify or deem applicable any reserve, special deposit or similar requirement
(including, without limitation, any such requirement imposed by the Board)
against assets of, deposits with or for the account of, or credit extended by,
the Lender, or impose on the Lender or the London interbank market any other
condition affecting this Agreement or Eurodollar Loans made by the Lender or any
Letter of Credit; and the result of any of the foregoing shall be to increase
the cost to the Lender of making or maintaining any Eurodollar Loan (or of
maintaining its obligation to make any such Loan) or to increase the cost to the
Lender of issuing or maintaining any Letter of Credit or to reduce the amount of
any sum received or receivable by the Lender hereunder (whether of principal,
interest or otherwise), then, upon demand from time to time by the Lender to the
Borrower, the Borrower will pay to the Lender, within 30 days after such demand
(which demand shall be accompanied by a certificate pursuant to Section
2.13(c)), such additional amount or amounts as will compensate the Lender for
such additional costs incurred or reduction suffered.

            (b) If the Lender (in its sole and absolute discretion) determines
that any Change in Law regarding capital requirements has or would have the
effect of reducing the rate of return on the Lender's capital or on the capital
of the Lender's holding company, if any, as a consequence of this Agreement or
the Loans made by, or Letters of Credit issued by, the Lender, to a level below
that which the Lender or the Lender's holding company could have achieved but
for such Change in Law (taking into consideration the Lender's policies and the
policies of the Lender's holding company with respect to capital adequacy), then
upon demand from time to time by the Lender to the Borrower, the Borrower shall
pay to the Lender, within 30 days after such demand (which demand shall be
accompanied by a certificate pursuant to Section 2.13(c)), such additional
amount or amounts as will compensate the Lender or the Lender's holding company,
for any such reduction suffered.

            (c) Each demand by the Lender to the Borrower under paragraph (a) or
(b) of this Section 2.13 shall be accompanied by a certificate of the Lender
setting forth the amount or amounts necessary to compensate the Lender or its
holding company, as the case may be, as specified in paragraph (a) or (b) of
this Section 2.13. Such certificate shall be conclusive so long as it reflects,
in reasonable detail, a reasonable basis for the calculation of the amounts set
forth therein and does not contain any manifest error. Failure or delay on the
part of the Lender to demand compensation pursuant to this Section 2.13 shall
not constitute a waiver of the Lender's right to demand such compensation;
PROVIDED that the Borrower shall not be required to compensate the Lender
pursuant to this Section 2.9 for any increased costs or reductions incurred more
than six (6) months prior to the date that Lender notifies the Borrower of the
Change in Law giving rise to such increased costs or reductions and of the
Lender's intention to claim compensation therefor; PROVIDED FURTHER that, if the
Change in Law giving rise to such increased costs or reductions is (i)
retroactive and (ii) occurred within such six (6) month period, then the six (6)
month period referred to above may be extended to include the period of
retroactive effect thereof,

                                      -30-
<PAGE>

but in no event any period prior to the Closing Date. In determining any amounts
necessary to compensate the Lender or its holding company, as the case may be,
as specified in paragraph (a) or (b) of this Section 2.13, the Lender will act
reasonably and in good faith and will, to the extent that the increased costs or
reductions in amounts received or receivable relate to the Lender's loans
generally and are not specifically attributable to the Loans hereunder, use
commercially reasonably averaging and attribution methods covering all loans
made by the Lender to similarly situated borrowers.

      2.14 BREAK FUNDING PAYMENTS.

            (a) In the event of (i) the payment of any principal of any
Eurodollar Loan other than on the last day of an Interest Period applicable
thereto (including as a result of an Event of Default), (ii) the conversion of
any Eurodollar Loan other than on the last day of the Interest Period applicable
thereto, or (iii) the failure to borrow, convert, continue or prepay any
Eurodollar Loan on the date specified in any notice delivered pursuant hereto
(regardless of whether such notice is permitted to be revocable and is revoked
in accordance herewith) then, in any such event, the Borrower shall compensate
the Lender for the associated loss and reasonably cost and expense attributable
to such event, as determined by the Lender in good faith.

            (b) A certificate of the Lender setting forth in reasonable detail
any amount or amounts that the Lender is entitled to receive pursuant to this
Section 2.14 and the basis for requiring such amount shall be delivered to the
Borrower and shall be conclusive absent manifest error. The Borrower shall pay
the Lender the amount shown as due on any such certificate within 10 days after
receipt thereof.

      2.15 TAXES.

            (a) Any and all payments by or on account of any obligation of the
Borrower hereunder shall be made free and clear of and without deduction for any
Taxes; PROVIDED that if the Borrower shall be required to deduct any Taxes
(other than Excluded Taxes) from such payments, then (i) the sum payable shall
be increased as necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section
2.15) the Lender receives an amount equal to the sum it would have received had
no such deductions been made, (ii) the Borrower shall make such deductions and
(iii) the Borrower shall pay the full amount deducted to the relevant
Governmental Authority in accordance with applicable law.

            (b) The Borrower shall indemnify the Lender, within 10 days after
written demand therefor, for the full amount of any Taxes (other than Excluded
Taxes) (including Taxes imposed or asserted on or attributable to amounts
payable under this Section 2.15) paid by the Lender (and any penalties, interest
and reasonable expenses arising therefrom or with respect thereto during the
period prior to the Borrower making the payment demanded under this paragraph
(b)), whether or not such Taxes were correctly or legally imposed or asserted by
the relevant Governmental Authority. A certificate as to the amount of such
payment or liability delivered to the Borrower by the Lender shall be conclusive
absent manifest error.

            (c) As soon as practicable after any payment of Taxes by the
Borrower to a Governmental Authority, the Borrower shall deliver to the Lender
the original or a certified copy of a receipt issued by such Governmental
Authority evidencing such payment, a copy of the return reporting such payment
or other evidence of such payment reasonably satisfactory to the Lender.

            (d) If the Lender receives payment of Taxes pursuant to paragraph
(b) of this Section 2.15, and subsequent to the date of such payment, recovers
all or any portion of such amount in the form

                                      -31-
<PAGE>

of a refund or rebate, the Lender shall apply such refund or rebate to the
prepayment of the Loans or, if no Loans shall then be outstanding, refund such
refund or rebate to the Borrower.

                           GUARANTEE BY THE GUARANTOR

      3.1 THE GUARANTEE. The Guarantor hereby guarantees to the Lender and its
successors and assigns the prompt payment in full when due (whether at stated
maturity, by acceleration or otherwise) of the Obligations. The Guarantor hereby
further agrees that if the Borrower shall fail to pay in full when due (whether
at stated maturity, by acceleration or otherwise) any of the Obligations, the
Guarantor will promptly pay the same, without any demand or notice whatsoever,
and that in the case of any extension of time of payment or renewal of any of
the Obligations, the same will be promptly paid in full when due (whether at
extended maturity, by acceleration or otherwise) in accordance with the terms of
such extension or renewal.

      3.2 OBLIGATIONS UNCONDITIONAL. The obligations of the Guarantor under
Section 3.1 are absolute and unconditional irrespective of the value,
genuineness, validity, regularity or enforceability of this Agreement, the other
Loan Documents or any other agreement or instrument referred to herein or
therein, or any substitution, release or exchange of any other guarantee of or
security for any of the Obligations, and, to the fullest extent permitted by
applicable law, irrespective of any other circumstance whatsoever that might
otherwise constitute a legal or equitable discharge or defense of a surety or
guarantor, it being the intent of this Section 3.2 that the obligations of the
Guarantor hereunder shall be absolute and unconditional under any and all
circumstances. Without limiting the generality of the foregoing, it is agreed
that the occurrence of any one or more of the following shall not alter or
impair the liability of the Guarantor hereunder which shall remain absolute and
unconditional as described above:

            (i) at any time or from time to time, without notice to such
      Guarantor, the time for any performance of or compliance with any of the
      Obligations shall be extended, or such performance or compliance shall be
      waived;

            (ii) any of the acts mentioned in any of the provisions hereof or of
      the other Loan Documents or any other agreement or instrument referred to
      herein or therein shall be done or omitted;

            (iii) the maturity of any of the Obligations shall be accelerated,
      or any of the Obligations shall be modified, supplemented or amended in
      any respect, or any right hereunder or under the other Loan Documents or
      any other agreement or instrument referred to herein or therein shall be
      waived or any other guarantee of any of the Obligations or any security
      therefor shall be released or exchanged in whole or in part or otherwise
      dealt with; or

            (iv) any lien or security interest granted to, or in favor of, the
      Lender as security for any of the Obligations shall fail to be perfected.

The Guarantor hereby expressly waives diligence, presentment, demand of payment,
protest and all notices whatsoever, and any requirement that the Lender exhaust
any right, power or remedy or proceed against the Borrower hereunder or under
the other Loan Documents or any other agreement or instrument referred to herein
or therein, or against any other Person under any other guarantee of, or
security for, any of the Obligations.

                                      -32-

      3.3 REINSTATEMENT. The obligations of the Guarantor under this Article 3
shall be automatically reinstated if and to the extent that for any reason any
payment by or on behalf of the Borrower in respect of the Obligations is
rescinded or must be otherwise restored by any holder of any of the Obligations,
whether as a result of any proceedings in bankruptcy or reorganization or
otherwise, and the Guarantor agrees that it will indemnify the Lender on demand
for all reasonable costs and expenses (including reasonable fees and expenses of
counsel) incurred by the Lender in connection with such rescission or
restoration, including any such costs and expenses incurred in defending against
any claim alleging that such payment constituted a preference, fraudulent
transfer or similar payment under any bankruptcy, insolvency or similar law.

      3.4 SUBROGATION. Until such time as the Obligations shall have been
indefeasibly paid in full, the Guarantors hereby waives all rights of
subrogation or contribution, whether arising by contract or operation of law
(including, without limitation, any such right arising under the Federal
Bankruptcy Code of 1978, as amended) or otherwise by reason of any payment by it
pursuant to the provisions of this Article 3 and further agrees with the
Borrower for the benefit of each creditor of the Borrower (including, without
limitation, the Lender) that any such payment by it shall constitute a
contribution of capital by the Guarantor to the Borrower.

      3.5 REMEDIES. The Guarantor agrees that, as between the Guarantor and the
Lender, the Obligations of the Borrower hereunder may be declared to be
forthwith due and payable as provided in Section 9.1 (and shall be deemed to
have become automatically due and payable in the circumstances provided in
Section 9.1) for purposes of Section 3.1 notwithstanding any stay, injunction or
other prohibition preventing such declaration (or such Obligations from becoming
automatically due and payable) as against the Borrower and that, in the event of
such declaration (or such Obligations being deemed to have become automatically
due and payable), such Obligations (whether or not due and payable by the
Borrower) shall forthwith become due and payable by the Guarantor for purposes
of Section 3.1.

      3.6 INSTRUMENT FOR THE PAYMENT OF MONEY. The Guarantor hereby acknowledges
that the guarantee in this Article 3 constitutes an instrument for the payment
of money, and consents and agrees that the Lender, at its sole option, in the
event of a dispute by the Guarantor in the payment of any moneys due hereunder,
shall have the right to summary judgment or such other expedited procedure as
may be available for a suit on a note or other instrument for the payment of
money.

      3.7 CONTINUING GUARANTEE. The guarantee in this Article 3 is a continuing
guarantee, and shall apply to all Obligations whenever arising.

      3.8 GENERAL LIMITATION ON AMOUNT OF OBLIGATIONS GUARANTEED. In any action
or proceeding involving any state or non-U.S. corporate law, or any state or
Federal or non-U.S. bankruptcy, insolvency, reorganization or other law
affecting the rights of creditors generally, if the obligations of the Guarantor
under Section 3.1 would otherwise be held or determined to be void, invalid or
unenforceable, or subordinated to the claims of any other creditors, on account
of the amount of its liability under Section 3.1, then, notwithstanding any
other provision hereof to the contrary, the amount of such liability shall,
without any further action by the Guarantor, the Lender, or other Person, be
automatically limited and reduced to the highest amount that is valid and
enforceable and not subordinated to the claims of other creditors as determined
in such action or proceeding.

Credit Party; and all guaranties and security therefor, and all letters of
credit and other supporting obligations in respect of such debts, obligations

Any of the foregoing terms which are defined in the Uniform Commercial Code
shall have the meaning provided in the Uniform Commercial Code, as amended and
in effect from time to time, as supplemented and expanded by the foregoing.

      4.2 SPECIAL WARRANTIES AND COVENANTS OF THE BORROWER. Each Credit Party
hereby warrants and covenants to the Lender that:

            (a) Such Credit Party has delivered to the Lender a Perfection
Certificate in substantially the form of EXHIBIT C hereto. All information set
forth in such Perfection Certificate is true and correct in all material
respects and the facts contained in such Perfection Certificate are accurate in
all material respects as of the date of this Agreement. Each Credit Party agrees
to supplement its Perfection Certificate promptly after obtaining information
which would require a correction or addition to such Perfection Certificate.

            (b) No Credit Party will change its jurisdiction of organization,
principal or any other place of business, or the location of any Collateral from
the locations set forth in the Perfection Certificate delivered by such Credit
Party, or make any change in its name or conduct its business operations under
any fictitious business name or trade name, without, in any such case, at least
thirty (30) days' prior written notice to the Lender; provided that the
inventory of such Credit Party may be in the possession of manufacturers or
processors in any jurisdiction in which all necessary UCC financing statements
have been filed by the Lender and with respect to which the Lender has received
waiver letters from all landlords, warehousemen and processors in form and
substance acceptable to Lender.

            (c) Except for Collateral that is obsolete or no longer used in
their business, the Credit Parties will keep the Collateral in good order and
repair (normal wear excepted) and adequately insured at all times in accordance
with the provisions of Section 7.5. The Credit Parties will pay promptly when
due all taxes and assessments on the Collateral or for its use or operation,
except for taxes and assessments permitted to be contested as provided in
Section 7.4. Following the occurrence and during the continuance of an Event of
Default, the Lender may at its option discharge any taxes or Liens to which any
Collateral is at any time subject (other than Permitted Liens), and may, upon
the failure of the Credit Parties to do so in accordance with this Agreement,
purchase insurance on any Collateral and pay for the repair, maintenance or
preservation thereof, and each Credit Party agrees to reimburse the Lender on
demand for any payments or expenses incurred by the Lender pursuant to the
foregoing authorization and any unreimbursed amounts shall constitute
Obligations for all purposes hereof.

            (d) The Lender may from time to time request and each Credit Party
shall deliver copies of all customer lists and vendor lists.

            (e) To the extent, if any, that such Credit Party's signature is
required therefor, such Credit Party will promptly execute and deliver to the
Lender such financing statements and amendments thereto, certificates and other
documents or instruments as may be necessary to enable the Lender to perfect or
from time to time renew the security interest granted hereby, including, without
limitation, such financing statements and amendments thereto, certificates and
other documents as may be necessary to perfect a security interest in any
additional Collateral hereafter acquired by such Credit Party or in any
replacements or proceeds thereof. Each Credit Party authorizes and appoints the
Lender, in case of need,

                                      -35-
<PAGE>

to execute such financing statements, certificates and other documents
pertaining to the Lender's security interest in the Collateral in its stead if
such Credit Party's signature is required therefor and such Credit Party fails
to so execute such documents, with full power of substitution, as such Debtor's
attorney in fact.

            (f) Each Credit Party hereby irrevocably authorizes the Lender, at
any time and from time to time, to file in any jurisdiction financing statements
and amendments thereto that (i) indicate the Collateral (x) as all assets of
such Credit Party or words of similar effect, regardless of whether any
particular asset falls within the scope of Article 9 of the Uniform Commercial
Code of the Commonwealth of Massachusetts or such jurisdiction or (y) as being
of an equal or lesser scope or with greater detail and (ii) which contain any
other information required by Article 9 of the Uniform Commercial Code
(including Part 5 thereof) for the sufficiency or filing office acceptance of
any financing statement or amendment, including whether (A) such Credit Party is
an organization, the type of organization and any organization identification
number issued to such Credit Party and (B) in the case of a financing statement
filed as a fixture filing or indicating Collateral as as-extracted collateral or
timber to be cut, a sufficient description of the real property to which the
Collateral relates. Each Credit Party agrees to furnish any such information to
the Lender promptly upon request. Each Credit Party also ratifies its
authorization for the Lender to have filed in any Uniform Commercial Code
jurisdiction any like initial financing statements or amendments thereto if
filed prior to the date hereof.

            (g) Each Credit Party agrees that it will join with the Lender in
executing and, at its own expense, will file and refile, or permit the Lender to
file and refile such other documents (including, without limitation, this
Agreement and licenses to use software and other property protected by
copyright), in such offices (including, without limitation, the PTO, the United
States Copyright Office, and appropriate state patent, trademark and copyright
offices), as the Lender may reasonably deem necessary or appropriate, wherever
required or permitted by law in order to perfect and preserve the rights and
interests granted to the Lender in Patents, Trademarks and Copyrights hereunder.
Each Credit Party will give the Lender notice of each office at which records of
such Credit Party pertaining to all intangible items of Collateral are kept.
Except as may be provided in such notice, the records concerning all intangible
Collateral are and will be kept at the address shown in the Perfection
Certificate for such Credit Party as the principal place of business of such
Credit Party.

            (h) The Credit Parties are the sole and exclusive owners of the
websites and domain names listed on SCHEDULE 4.2 of the Disclosure Schedules and
have registered such domain names with the applicable authority for registration
of the same which provides for the exclusive use by the Credit Parties of such
domain names. The websites do not contain any material, the publication of which
may result in (a) the violation of rights of any person or (b) a right of any
person against the publisher or distributor of such material.

            (i) The Credit Parties shall, annually by the end of the first
calendar quarter following the previous calendar year, provide written notice to
the Lender of all applications for registration of Patents, Trademarks or
Copyrights, to the extent such applications exist, made during the preceding
calendar year. The Credit Parties shall file and prosecute diligently all
applications for registration of Patents, Trademarks or Copyrights now or
hereafter pending that would be necessary to the business of the Credit Parties
to which any such applications pertain, and to do all acts, in any such
instance, necessary to preserve and maintain all rights in such registered
Patents, Trademarks or Copyrights unless such Patents, Trademarks or Copyrights
are not material to the business of the Credit Parties, as reasonably determined
by the Credit Parties consistent with prudent and commercially reasonable
business practices. Any and all costs and expenses incurred in connection with
any such actions shall be borne by the Credit Parties. Except in accordance with
prudent and commercially reasonable business practices, no Credit Party shall
abandon any right to file a Patent, Trademark or Copyright application or any
pending Patent, Trademark or

                                      -36-
<PAGE>

 Copyright application or any registered Patent,
Trademark or Copyright, in each case material to its business, without the
consent of the Lender.

            (j) The domain name servers used in connection with the domain names
of the Credit Parties and all other relevant information pertaining to such
domain names, and the administrative contacts used in connection with the
registration of such domain names are identified on SCHEDULE 4.2 of the
Disclosure Schedules. The Credit Parties will not change such domain name
servers without 10 days' prior notice to the Lender. The Credit Parties will not
cause a change in the identity of any domain name administrative contact without
10 days' prior notice to the Lender.

            (k) If any Credit Party is, now or at any time hereafter, a
beneficiary under a letter of credit, such Credit Party will promptly notify the
Lender thereof and, at the request and option of the Lender, such Credit Party
shall use its best efforts to either (i) arrange for the issuer and any
confirmer or other nominated person of such letter of credit to consent to an
assignment (in form and substance satisfactory to the Lender) to the Lender of
the proceeds of the letter of credit or (ii) arrange for the Lender to become
the transferee beneficiary (pursuant to an agreement in form and substance
satisfactory to the Lender) of the letter of credit, with the Lender agreeing,
in each case, that the proceeds of the letter of credit are to be applied by the
Lender against the Obligations as provided in this Agreement.

            (l) To the extent any Credit Party shall, now or at any time
hereafter, hold or acquire any promissory note or other instrument or tangible
chattel paper in an amount greater than $150,000, such Credit Party will
promptly notify the Lender thereof and, at the request and option of the Lender,
such Credit Party will deliver such promissory note or other instrument or
tangible chattel paper to the Lender to be held as Collateral hereunder,
together with an endorsement thereof reasonably satisfactory in form and
substance to the Lender.

            (m) If, now or at any time hereafter, any Credit Party shall obtain
or hold any investment property or electronic chattel paper in an amount greater
than $150,000, such Credit Party will promptly notify the Lender thereof and, at
the request and option of the Lender, such Credit Party will take or cause to be
taken such steps as the Lender may reasonably request for the Lender to obtain
"control" (as provided in Sections 9-105 and 9-106 of the Uniform Commercial
Code of the Commonwealth of Massachusetts, as amended and in effect from time to
time) of such Collateral.

            (n) No Credit Party holds any commercial tort claims, as defined in
Article 9 of the Uniform Commercial Code, except as indicated in the Perfection
Certificate attached hereto as EXHIBIT C. If any Credit Party shall at any time
acquire a commercial tort claim, such Credit Party shall immediately notify the
Lender in a signed writing of the brief details thereof and grant to the Lender
in such writing a security interest therein and in the proceeds thereof, all
upon the terms of this Agreement, with such writing to be in form and substance
reasonably satisfactory to the Lender.

            (o) If the Borrower has accounts receivable in respect of which the
account debtor is located in Minnesota, the Borrower represents and warrants
that the Borrower has filed and shall file all legally-required Notice of
Business Activities Reports and comparable reports with the appropriate
government authorities.

      4.3 COLLECTION OF PROCEEDS OF ACCOUNTS RECEIVABLE. The Lender (and all
Persons designated by the Lender for such purpose) may, at any time and from
time to time after the occurrence and during the continuance of an Event of
Default, whether before or after notification to any account debtor and whether
before or after the maturity of any of the Obligations, (i) enforce collection
of any accounts receivable or contract rights of the Credit Parties by suit or
otherwise; (ii) exercise all of the rights and remedies of the Credit Parties
with respect to proceedings brought to collect any accounts

                                      -37-
<PAGE>

receivable; (iii) surrender, release or exchange all or any part of any accounts
receivable of the Credit Parties, or compromise or extend or renew for any
period (whether or not longer than the original period) any indebtedness
thereunder; (iv) sell or assign any account receivable of the Credit Parties
upon such terms, for such amount and at such time or times as the Lender deems
advisable; (v) prepare, file and sign the names of the Credit Parties on any
proof of claim in bankruptcy or other similar document against any account
debtor indebted on an account receivable of the Credit Parties; and (vi) do all
other acts and things which are necessary, in the Lender's sole discretion, to
fulfill the Obligations of the Credit Parties under this Agreement and to allow
the Lender to collect the accounts receivable. In addition to any other
provision hereof or in any of the other Loan Documents, the Lender may at any
time on or after the occurrence of an Event of Default, at the sole expense of
the Credit Parties, notify any parties obligated on any of the accounts
receivable of the Credit Parties to make payment directly to the Lender of any
amounts due or to become due thereunder.

      4.4 FIXTURES, ETC. It is the intention of the parties hereto that (except
for Collateral located on any Mortgaged Property) none of the Collateral shall
become fixtures and each Credit Party will take all such reasonable action or
actions as may be necessary to prevent any of the Collateral from becoming
fixtures. Without limiting the generality of the foregoing, each Credit Party
will, if requested by the Lender, use commercially reasonable efforts to obtain
waivers of Liens, in form satisfactory to the Lender, from each lessor of real
property on which any of the Collateral is or is to be located to the extent
requested by the Lender.

      4.5 RIGHT OF LENDER TO DISPOSE OF COLLATERAL, ETC. Upon the occurrence and
during the continuance of any Event of Default, but subject to the provisions of
the Uniform Commercial Code or other applicable law, in addition to all other
rights under applicable law and under the Loan Documents, the Lender shall have
the right to take possession of the Collateral and, in addition thereto, the
right to enter upon any premises on which the Collateral or any part thereof may
be situated and remove the same therefrom. The Lender may require the Credit
Parties to make the Collateral (to the extent the same is moveable) available to
the Lender at a place to be designated by the Lender or transfer any information
related to the Collateral to the Lender by electronic medium. Unless the
Collateral is perishable or threatens to decline speedily in value or is of a
type customarily sold on a recognized market, the Lender will give the Credit
Parties at least seven (7) days' prior written notice of the time and place of
any public sale thereof or of the time after which any private sale or any other
intended disposition thereof is to be made. Any such notice shall be deemed to
meet any requirement hereunder or under any applicable law (including the
Uniform Commercial Code) that reasonable notification be given of the time and
place of such sale or other disposition.

      4.6 RIGHT OF LENDER TO USE AND OPERATE COLLATERAL, ETC. Upon the
occurrence and during the continuance of any Event of Default, subject to the
provisions of the Uniform Commercial Code or other applicable law, the Lender
shall have the right and power (a) to take possession of all or any part of the
Collateral, and to exclude the Credit Parties and all persons claiming under the
Credit Parties wholly or partly therefrom, and thereafter to hold, store, and/or
use, operate, manage and control the same, and (b) to grant a license to use, or
cause to be granted a license to use, any or all of the Patents, Trademarks and
Copyrights (in the case of Trademarks, along with the goodwill associated
therewith), but subject to the terms of any licenses. Upon any such taking of
possession, the Lender may, from time to time, at the expense of the Credit
Parties, make all such repairs, replacements, alterations, additions and
improvements to and of the Collateral as the Lender may deem proper. In any such
case the Lender shall have the right to manage and control the Collateral and to
carry on the business and to exercise all rights and powers of the Credit
Parties in respect thereto as the Lender shall deem best, including the right to
enter into any and all such agreements with respect to the operation of the
Collateral or any part thereof as the Lender may see fit; and the Lender shall
be entitled to collect and receive all rents, issues, profits, fees, revenues
and other income of the same and every part thereof. Such rents, issues,
profits, fees,

                                      -38-
<PAGE>

revenues and other income shall be applied to pay the expenses of holding and
operating the Collateral and of conducting the business thereof, and of all
maintenance, repairs, replacements, alterations, additions and improvements, and
to make all payments which the Lender may be required or may elect to make, if
any, for taxes, assessments, insurance and other charges upon the Collateral or
any part thereof, and all other payments which the Lender may be required or
authorized to make under any provision of this Agreement (including legal costs
and reasonable attorneys' fees). The Lender shall apply the remainder of such
rents, issues, profits, fees, revenues and other income as provided in Section
4.7.

      4.7 PROCEEDS OF COLLATERAL. After deducting all reasonable costs and
expenses of collection, storage, custody, sale or other disposition and delivery
(including reasonable legal costs and attorneys' fees) and all other charges
against the Collateral, the Lender shall apply the residue of the proceeds of
any such sale or disposition to the Obligations in accordance with the terms
hereof and any surplus shall be returned to the Credit Parties or to any Person
or party lawfully entitled thereto. In the event the proceeds of any sale, lease
or other disposition of the Collateral are insufficient to pay all of the
Obligations in full, the Credit Parties will be liable for the deficiency,
together with interest thereon at the Post-Default Rate, and the cost and
expenses of collection of such deficiency, including (to the extent permitted by
law), without limitation, reasonable attorneys' fees, expenses and
disbursements.

                                    ARTICLE 5

                         REPRESENTATIONS AND WARRANTIES

      Each Credit Party represents and warrants to the Lender, that:

      5.1 ORGANIZATION; POWERS. Each Credit Party has been duly formed or
organized and is validly existing and in good standing under the laws of its
jurisdiction of organization. Each Credit Party has all requisite power and
authority to carry on its business as now conducted and is qualified to do
business in, and is in good standing in, every jurisdiction where such
qualification is required, except where the failure to have such power or
authority or to be so qualified or in good standing, individually or in the
aggregate, could not reasonably be expected to result in a Material Adverse
Effect.

      5.2 AUTHORIZATION; ENFORCEABILITY. The borrowing of the Loans, the
guaranty of the Obligations, and the grant of security interests pursuant to the
Loan Documents, as applicable, are within the power and authority of the Credit
Parties and have been duly authorized by all necessary action on the part of the
Credit Parties. This Agreement and the other Loan Documents have been duly
authorized, executed and delivered by the Credit Parties and constitute legal,
valid and binding obligations of the Credit Parties, enforceable in accordance
with their respective terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium or other laws affecting creditors' rights generally
and subject to general principles of equity, regardless of whether considered in
a proceeding in equity or at law.

      5.3 GOVERNMENTAL APPROVALS; NO CONFLICTS. The borrowing of the Loans and
the grant of the security interests pursuant to the Loan Documents (a) do not
require any consent or approval of, registration or filing with, or any other
action by, any Governmental Authority which has not been obtained, except as
disclosed on SCHEDULE 5.3 of the Disclosure Schedules, (b) will not violate any
applicable law, policy or regulation or the organizational documents of the
Credit Parties or any order of any Governmental Authority, (c) will not violate
or result in a default under any indenture, agreement or other instrument
binding upon the Credit Parties, or any assets of the Credit Parties, or give
rise to a right thereunder to require any payment to be made by the Credit
Parties, where such violation or default or right to payment would have a
Material Adverse Effect, and (d) except for the Liens created by the Loan
Documents, will not result in the creation or imposition of any Lien on any
asset of the Credit Parties.

                                      -39-
<PAGE>

      5.4 FINANCIAL CONDITION; NO MATERIAL ADVERSE CHANGE.

            (a) The Credit Parties have heretofore delivered to the Lender the
following financial statements:

            (i) the consolidated balance sheets and statements of operations,
      shareholders' equity and cash flows of the Borrower and all Subsidiaries,
      as of and for the fiscal years ended December 31, 1999, and December 31,
      2000, and December 31, 2001, audited and accompanied by an opinion of the
      Borrower's independent public accountants;

            (ii) the unaudited consolidated balance sheet and statements of
      operations, shareholder's equity and cash flows of the Borrower and all
      Subsidiaries, as of and for the fiscal year-to-date period ended September
      30, 2002, accompanied by a certificate of a Designated Financial Officer
      which certifies that such financial statements fairly present the
      financial condition of the Borrower and all Subsidiaries as at such date
      and the results of the operations of the Borrower and all Subsidiaries for
      the period ended on such date and that all such financial statements,
      including the related schedules and notes thereto have been prepared in
      all material respects in accordance with GAAP applied consistently
      throughout the periods involved, except as disclosed on SCHEDULE 5.4 of
      the Disclosure Schedules; and

            (iii) the projected booking, sales and net income for the Borrower
      and all Subsidiaries for fiscal year 2003.

Except as disclosed on SCHEDULE 5.4 of the Disclosure Schedules, such financial
statements (except for the projections) present fairly, in all material
respects, the respective consolidated financial position and results of
operations and cash flows of the Borrower and its Subsidiaries as of such
respective dates and for such periods in accordance with GAAP, subject to
year-end audit adjustments and the absence of footnotes in the case of such
unaudited or PRO FORMA statements. The projections were prepared by the Borrower
in good faith and were based on assumptions that were reasonable when made.

            (b) Except as disclosed on SCHEDULE 5.4 of the Disclosure Schedules,
since June 30, 2002, there has been no material adverse change in the business,
assets, operations or condition, financial or otherwise, of the Credit Parties
from that set forth in the June 30, 2002 financial statements referred to in
clause (ii) of paragraph (a) above.

            (c) None of the Credit Parties has, on the date hereof, any
contingent liabilities, liabilities for taxes, unusual forward or long-term
commitments or unrealized or anticipated losses from any unfavorable commitments

Reserve System.

initial Loans hereunder and the other transactions contemplated hereby:

their present fair saleable value on a going concern basis (I.E., the amount
that may be realized within a reasonable time, considered to be six months to

sale and delivery of goods or rendition of services by the Borrower in the
ordinary course of its business and in accordance with the terms and conditions

in the case of goods, title to the goods has passed from the Borrower to the
account debtor;

stated in the duplicate invoice covering such sale or rendition of services, a
copy of which has been furnished or is available to the Lender;

            (d) Each account receivable, and the Lender's security interest
therein, is not, and will not (by voluntary act or omission of the Credit
Parties) be in the future, subject to any offset, Lien, deduction, defense,
dispute, counterclaim or any other adverse condition except for disputes
resulting in returned goods where the amount in controversy is deemed by the
Lender to be immaterial, and each such account receivable is absolutely owing to
the Borrower and is not contingent in any respect or for any reason;

            (e) The Borrower has not made any agreement with any account debtor
for any extension, compromise, settlement or modification of any account
receivable or any deduction therefrom, except discounts or allowances which are
granted by the Borrower in the ordinary course of its businesses for prompt
payment and which are reflected in the calculation of the net amount of each
respective invoice related thereto and are reflected in the Borrowing Base
Certificates furnished to the Lender hereunder;

            (f) To the best knowledge of the Borrower, the account debtor under
each account receivable had the capacity to contract at the time any contract or
other document giving rise to an account receivable was executed and such
account debtor is not insolvent; and

            (g) To the best knowledge of the Borrower, there are no proceedings
or actions which are threatened or pending against any account debtor which

Credit Party, which claims or liabilities (insofar as they are payable by any
Credit Party but after deducting any portion thereof which is reasonably
expected to be paid by other credit worthy Persons jointly and severally liable

following actions, at the same or different times: (i) terminate the Revolving
Credit Commitment, and thereupon the Revolving Credit Commitment shall terminate
immediately, (ii) notify the Borrower that the outstanding principal of the
Loans shall bear interest at the Post-Default Rate, and thereupon the
outstanding principal of the Loans shall bear interest at the Post-Default Rate,
(iii) declare the Loans then outstanding to be due and payable in whole (or in
part, in which case any principal not so declared to be due and payable may
thereafter be declared to be due and payable), and thereupon the principal of
the Loans so declared to be due and payable, together with accrued interest
thereon and all fees and other Obligations, shall become due and payable
immediately, without presentment, demand, protest or other notice of any kind,
all of which are hereby waived by the Credit Parties, and (iv) the Lender and
any other Affiliate of the Lender may exercise all of the rights as secured
party and mortgagee hereunder or under the other Loan Documents; and in case of
any event with respect to the Credit Parties

                                      -63-
<PAGE>

or any Subsidiary described in clause (g) or (h) of this Section 9.1, the
Revolving Credit Commitment shall automatically terminate, the principal of the
Loans then outstanding shall automatically bear interest at the Post-Default
Rate, the principal of the Loans then outstanding, together with accrued
interest thereon and all fees and other Obligations shall automatically become
due and payable, and the Borrower shall provide cash collateral in accordance
with Section 2.4(g) without presentment, demand, protest or other notice of any
kind, all of which are hereby waived by the Credit Parties, and the Lender shall
be permitted to exercise such rights as secured party and mortgagee hereunder or
under the other Loan Documents to the extent permitted by applicable law.

      9.2 RECEIVERSHIP. Without limiting the generality of the foregoing or
limiting in any way the rights of the Lender hereunder or under the other Loan
Documents or otherwise under applicable law, at any time after (i) the entire
principal balance of any Loan shall have become due and payable (whether at
maturity, by acceleration or otherwise) and (ii) the Lender shall have provided
to the Borrower not less than ten (10) days' prior written notice of its
intention to apply for a receiver, the Lender shall be entitled to apply for and
have a receiver appointed under state or federal law by a court of competent
jurisdiction in any action taken by the Lender to enforce its rights and
remedies hereunder and under the other Loan Documents in order to manage,
protect, preserve, sell and otherwise dispose of all or any portion of the
Collateral and continue the operation of the business of the Credit Parties, and
to collect all revenues and profits thereof and apply the same to the payment of
all expenses and other charges of such receivership, including the compensation
of the receiver, and to the payment of the Loans and other fees and expenses due
hereunder and under the Loan Documents as aforesaid until a sale or other
disposition of such Collateral shall be finally made and consummated. TO THE
EXTENT PERMITTED BY APPLICABLE LAW, EACH CREDIT PARTY HEREBY IRREVOCABLY
CONSENTS TO AND WAIVES ANY RIGHT TO OBJECT TO OR OTHERWISE CONTEST THE
APPOINTMENT OF A RECEIVER AS PROVIDED ABOVE. EACH CREDIT PARTY (I) GRANTS SUCH
WAIVER AND CONSENT KNOWINGLY AFTER HAVING DISCUSSED THE IMPLICATIONS THEREOF
WITH COUNSEL, (II) ACKNOWLEDGES THAT (A) THE UNCONTESTED RIGHT TO HAVE A
RECEIVER APPOINTED FOR THE FOREGOING PURPOSES IS CONSIDERED ESSENTIAL BY THE
LENDER IN CONNECTION WITH THE ENFORCEMENT OF ITS RIGHTS AND REMEDIES HEREUNDER
AND UNDER THE OTHER LOAN DOCUMENTS, AND (B) THE AVAILABILITY OF SUCH APPOINTMENT
AS A REMEDY UNDER THE FOREGOING CIRCUMSTANCES WAS A MATERIAL FACTOR IN INDUCING
THE LENDER TO MAKE THE LOANS TO THE BORROWER; AND (III) AGREES TO ENTER INTO ANY
AND ALL STIPULATIONS IN ANY LEGAL ACTIONS, OR AGREEMENTS OR OTHER INSTRUMENTS IN
CONNECTION WITH THE FOREGOING AND TO COOPERATE FULLY WITH THE LENDER IN
CONNECTION WITH THE ASSUMPTION AND EXERCISE OF CONTROL BY THE RECEIVER OVER ALL
OR ANY PORTION OF THE COLLATERAL. THE LENDER ACKNOWLEDGES AND AGREES THAT
NOTHING IN THIS SECTION 9.2 SHALL BE DEEMED TO CONSTITUTE A WAIVER OF THE RIGHT
OF THE CREDIT PARTIES TO FILE FOR PROTECTION UNDER TITLE 11 OF THE UNITED STATES
CODE AT ANY TIME.

Any party hereto may change its address or fax number for notices and other
communications hereunder by notice to the other parties hereto. All notices and
other communications given to any party hereto in accordance with the provisions
of this Agreement shall be deemed to have been given on the date of receipt.

      10.2 WAIVERS; AMENDMENTS.

            (a) No failure or delay by the Lender in exercising any right or
power hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights
and remedies of the Lender hereunder and under the other Loan Documents are
cumulative and are not exclusive of any rights or remedies that they would
otherwise have. No waiver of any provision of this Agreement or consent to any
departure by any Credit Party or Subsidiary therefrom shall in any event be
effective unless the same shall be permitted by paragraph (b) of this Section
10.2, and then such waiver or consent shall be effective only in the specific
instance and for the purpose for which given. Without limiting the generality of
the foregoing, the making of a Loan or issuance of a Letter of Credit shall not
be construed as a waiver of any Default, regardless of whether the Lender may
have had notice or knowledge of such Default at the time.

            (b) Neither this Agreement nor any other Loan Document (including,
without limitation, the Disclosure Schedules) nor any provision hereof or
thereof may be waived, amended or modified except pursuant to an agreement or
agreements in writing entered into by the Borrower and the Lender.

      10.3 EXPENSES; INDEMNITY: DAMAGE WAIVER.

            (a) The Credit Parties jointly and severally agree to pay, or
reimburse the Lender for paying, (i) all reasonable out-of-pocket expenses
incurred by the Lender and its Affiliates, including the reasonable fees,
charges and disbursements of Special Counsel, in connection with the preparation
of this Agreement and the other Loan Documents or any amendments, modifications
or waivers of the provisions hereof or thereof (whether or not the transactions
contemplated hereby or thereby shall be consummated), (ii) all reasonable
out-of-pocket expenses incurred by the Lender in connection with the issuance,
amendment, renewal or extension of any Letter of Credit or any demand for
payment thereunder, (iii) all reasonably out-of-pocket expenses incurred by the
Lender, including the reasonable fees, charges and disbursements of any counsel
for the Lender, in connection with the enforcement or protection of its rights
in connection with this Agreement and the other Loan Documents, including its
rights under this Section 10.3, or in connection with the Loans made or Letters
of Credit issued hereunder, including in connection with any workout,
restructuring or negotiations in respect thereof, and (iv) all Other Taxes
levied by any Governmental Authority in respect of this Agreement or any of the
other Loan Documents or any other document referred to herein or therein and all
taxes, assessments and other charges and

                                      -65-
<PAGE>

reasonable costs and expenses incurred in connection with any filing,
registration, recording or perfection of any security interest contemplated by
any Loan Document or any other document referred to therein.

            (b) The Credit Parties jointly and severally agree to indemnify the
Lender, each Affiliate of the Lender and each Related Party of any of the
foregoing Persons (each such Person being called an "Indemnitee") against, and
hold each Indemnitee harmless from, any and all losses, claims, damages,
liabilities and related expenses, including the reasonable fees, charges and
disbursements of any counsel for any Indemnitee and settlement costs, incurred
by or asserted against any Indemnitee arising out of, in connection with, or as
a result of (i) the execution or delivery of this Agreement, the other Loan
Documents or any agreement or instrument contemplated hereby, the performance by
the parties hereto and thereto of their respective obligations hereunder or
thereunder or the consummation of the transactions contemplated hereby or any
other transactions contemplated hereby or thereby, (ii) any Loan or Letter of
Credit or the use of the proceeds therefrom (including any refusal by the Lender
to honor a demand for payment under a Letter of Credit if the documents
presented in connection with such demand do not strictly comply with the terms
of such Letter of Credit), (iii) any actual or alleged presence or release of
Hazardous Materials (whenever occurring) on or from any of the property leased
or operated by any Credit Party during the term of this Agreement, or any
Environmental Liability of any Credit Party related in any way to such
properties which is caused by the act or failure to act of any Credit Party, or
(iv) any actual or prospective claim, litigation, investigation or proceeding
relating to any of the foregoing, whether based on contract, tort or any other
theory and regardless of whether any Indemnitee is a party thereto; PROVIDED
that such indemnity shall not, as to any Indemnitee, be available to the extent
that such losses, claims, damages, liabilities or related expenses are
determined by a court of competent jurisdiction by final and nonappealable
judgment to have resulted from the gross negligence or willful misconduct of
such Indemnitee. The Credit Parties' indemnification of each Indemnitee with
respect to compliance with Environmental Laws in connection with the Material
Owned Properties is set forth in the Hazardous Materials Indemnity Agreement.

            (c) To the extent permitted by applicable law, none of the Credit
Parties shall assert, and the Credit Parties hereby waive, any claim against any
Indemnitee, on any theory of liability, for special, indirect, consequential or
punitive damages (as opposed to direct or actual damages) arising out of, in
connection with, or as a result of, this Agreement, the other Loan Documents or
any agreement or instrument contemplated hereby or thereby, the transactions
contemplated hereby, any Loan or Letter of Credit or the use of the proceeds
thereof.

            (d) All amounts due under this Section 10.3 shall be payable
promptly after written demand therefor.

      10.4 SUCCESSORS AND ASSIGNS.

            (a) The provisions of this Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and assigns
permitted hereby, except that no Credit Party may assign or otherwise transfer
any of its rights or obligations hereunder without the prior written consent of
the Lender (and any attempted assignment or transfer without such consent shall
be null and void). Nothing in this Agreement, expressed or implied, shall be
construed to confer upon any Person (other than the parties hereto, their
respective successors and assigns permitted hereby and, to the extent expressly
contemplated hereby, the Related Parties of the Lender), any legal or equitable
right, remedy or claim under or by reason of this Agreement.

            (b) The Lender may at any time and from time to time, upon the prior
written consent of the Borrower, which consent shall not be unreasonably
withheld (except that no such consent shall be required if an Event of Default
shall have occurred and be continuing), assign to one or more

                                      -66-
<PAGE>

assignees all or a portion of its rights and obligations under this Agreement
(including all or a portion of the Revolving Credit Commitment and the Loans at
the time owing to the Lender); PROVIDED that, except in the case of an
assignment of the entire remaining amount of the Lender's aggregate Revolving
Credit Commitment and the Loans, the aggregate amount of the Revolving Credit
Commitments and Loans of the Lender subject to each such assignment shall not be
less than $1,000,000 unless the Borrower otherwise consents (except that no such
consent shall be required if an Event of Default shall have occurred and be
continuing).

            (c) The Lender may at any time and from time to time, sell
participations to one or more banks or other entities (a "Participant") in all
or a portion of the Lender's rights and obligations under this Agreement
(including all or a portion of the Revolving Credit Commitment and the Loans
owing to it); PROVIDED that (i) the Lender's obligations under this Agreement
shall remain unchanged, (ii) the Lender shall remain solely responsible to the
other parties hereto for the performance of such obligations and (iii) the
Borrower shall continue to deal solely and directly with the Lender in
connection with the Lender's rights and obligations under this Agreement. The
Borrower agrees that each Participant shall be entitled to the benefits of this
Agreement to the same extent as if it were a Lender and had acquired its
interest by assignment pursuant to paragraph (b) of this Section 10.4; PROVIDED
that a Participant shall not be entitled to receive any greater payment under
this Agreement than the Lender would have been entitled to receive with respect
to the participation sold to such Participant, unless the sale of the
participation to such Participant is made with the Borrower's prior written
consent.

            (d) The Lender may at any time pledge or assign a security interest
in all or any portion of its rights under this Agreement to secure obligations
of the Lender, including any such pledge or assignment to a Federal Reserve
Bank, and this Section shall not apply to any such pledge or assignment of a
security interest; PROVIDED that no such pledge or assignment of a security
interest shall release the Lender from any of its obligations hereunder or
substitute any such assignee for the Lender as a party hereto.

            (e) The Lender may furnish any information concerning the Credit
Parties or any Subsidiary in the possession of the Lender from time to time to
assignees and participants (including prospective assignees and participants)
subject, however, to and so long as the recipient agrees in writing to be bound
by, the provisions of Section 10.13. The Credit Parties shall assist the Lender
in effectuating any assignment or participation pursuant to this Section 10.4 in
whatever manner the Lender reasonably deems necessary, including participation
in meetings with prospective transferees.

      10.5 SURVIVAL. All covenants, agreements, representations and warranties
made by the Credit Parties herein and in the other Loan Documents, and in the
certificates or other instruments delivered in connection with or pursuant to
this Agreement and the other Loan Documents, shall be considered to have been
relied upon by the other parties hereto and shall survive the execution and
delivery of this Agreement and the other Loan Documents and the making of any
Loans and issuance of any Letters of Credit, regardless of any investigation
made by any such other party or on its behalf and notwithstanding that the
Lender may have had notice or knowledge of any Default or incorrect
representation or warranty at the time any credit is extended hereunder, and
shall continue in full force and effect so long as the principal of or any
accrued interest on any Loan or any fee or any other Obligation payable under
this Agreement or the other Loan Documents is outstanding and unpaid or any
Letter of Credit is outstanding and so long as the Revolving Credit Commitment
has not expired or terminated. The provisions of Sections 2.13, 2.15 and 10.3
shall survive and remain in full force and effect regardless of the consummation
of the transactions contemplated hereby, the repayment of the Loans, the
expiration or termination of the Letters of Credit and the Revolving Credit
Commitment or the termination of this Agreement or any other Loan Document or
any provision hereof or thereof.

      10.6 COUNTERPARTS; INTEGRATION; REFERENCES TO AGREEMENT; EFFECTIVENESS.
This Agreement may be executed in counterparts (and by different parties hereto
on different counterparts), each of which shall constitute an original, but all
of which when taken together shall constitute a single contract. This Agreement
and any separate letter agreements with respect to fees payable to the Lender or
its counsel constitute the entire contract among the parties relating to the
subject matter hereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof. Whenever
there is a reference in any Loan Document or UCC Financing Statement to the
"Credit Agreement" to which the Lender and the Credit Parties are parties, such
reference shall be deemed to be made to this Agreement among the parties hereto.
Except as provided in Section 6.1, this Agreement shall become effective when it
shall have been executed by the Lender and when the Lender shall have received
counterparts hereof which, when taken together, bear the signatures of each of
the other parties hereto, and thereafter shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and assigns.
Delivery of an executed counterpart of a signature page of this Agreement by
telecopy shall be effective as delivery of a manually executed counterpart of
this Agreement.

      10.7 SEVERABILITY. Any provision of this Agreement held to be invalid,
illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such invalidity, illegality or unenforceability
without affecting the validity, legality and enforceability of the remaining
provisions hereof; and the invalidity of a particular provision in a particular
jurisdiction shall not invalidate such provision in any other jurisdiction.

      10.8 RIGHT OF SETOFF. Each of the Credit Parties hereby grants to the
Lender and each Affiliate of the Lender that from time to time maintains any
deposit accounts, holds any funds or otherwise becomes indebted to the Credit
Parties, a security interest in all deposits (general or special, time or
demand, provisional or final) and funds at any time held and other indebtedness
at any time owing by the Lender or any such Affiliate of the Lender to or for
the credit or the account of any Credit Party as security for the Obligations,
and each of the Credit Parties hereby agrees that if an Event of Default shall
have occurred and be continuing, the Lender and each Affiliate of the Lender are
hereby authorized at any time and from time to time, to the fullest extent
permitted by law, to set off and apply any and all deposits (general or special,
time or demand, provisional or final) or other funds at any time held and other
indebtedness at any time owing by the Lender or any Affiliate of the Lender to
or for the credit or the account of any Credit Party against any and all of the
Obligations, irrespective of whether or not the Lender shall have made any
demand under this Agreement and although any of the Obligations may be
unmatured. The Lender shall use reasonable efforts to give written notice to the
Borrower promptly after the exercise by it or its Affiliates of the rights
granted to them in this Section; provided that the failure of the Lender to give
such notice shall not affect the rights of the Lender or its Affiliates
hereunder. The rights of the Lender and each Affiliate of the Lender under this
Section 10.8 are in addition to any other rights and remedies (including other
rights of setoff) which the Lender or any Affiliate of the Lender may have.

      10.9 [RESERVED].

      10.10 GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF PROCESS.

            (a) This Agreement shall be construed in accordance with and
governed by the law of The Commonwealth of Massachusetts.

            (b) Each party hereto hereby irrevocably and unconditionally
submits, for itself and its property, to the nonexclusive jurisdiction of the
courts of The Commonwealth of Massachusetts and of the United States District
Court for the District of Massachusetts, and any appellate court from any

                                      -68-
<PAGE>

thereof, in any action or proceeding arising out of or relating to this
Agreement or the other Loan Documents, or for recognition or enforcement of any
judgment, and each of the parties hereto hereby irrevocably and unconditionally
agrees that all claims in respect of any such action or proceeding may be heard
and determined in such Massachusetts court (or, to the extent permitted by law,
in such Federal court). Each of the parties hereto agrees that a final judgment
in any such action or proceeding shall be conclusive and may be enforced in
other jurisdictions by suit on the judgment or in any other manner provided by
law. Nothing in this Agreement shall affect any right that the Lender may
otherwise have to bring any action or proceeding relating to this Agreement
against any Credit Party or its properties in the courts of any jurisdiction.

            (c) Each party hereto hereby irrevocably and unconditionally waives,
to the fullest extent it may legally and effectively do so, any objection which
it may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement or the other Loan
Documents in any court referred to in paragraph (b) of this Section 10.10. Each
of the parties hereto hereby irrevocably waives, to the fullest extent permitted
by law, the defense of an inconvenient forum to the maintenance of such action
or proceeding in any such court.

            (d) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 10.1. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

      10.11 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING
TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON
CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK
TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER
PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10.11.

      10.12 HEADINGS. Article and Section headings and the Table of Contents
used herein are for convenience of reference only, are not part of this
Agreement and shall not affect the construction of, or be taken into
consideration in interpreting, this Agreement.

      10.13 CONFIDENTIALITY. The Lender agrees to keep confidential information
obtained by it pursuant hereto and the other Loan Documents confidential in
accordance with the Lender's customary practices and agrees that it will only
use such information in connection with the transactions contemplated by this
Agreement and not disclose any of such information other than (a) to the
Lender's employees, representatives, directors, attorneys, auditors, agents,
professional advisors, trustees or Affiliates who are advised of the
confidential nature of such information or to any direct or indirect contractual
counterparty in swap agreements or such contractual counterparty's professional
advisor (so long as such contractual counterparty or professional advisor to
such contractual counterparty agrees to be bound by the provisions of this
Section 10.13), (b) to the extent such information presently is or hereafter
becomes available to the Lender on a non-confidential basis from any source of
such information that is in the public domain at the time of disclosure, (c) to
the extent disclosure is required by law (including applicable securities law),
regulation, subpoena or judicial order or process (PROVIDED that notice of such
requirement or order shall be promptly furnished to the Borrower unless such
notice is legally prohibited) or requested or required by bank, securities,
insurance or investment company regulators or auditors or

                                      -69-
<PAGE>

any administrative body or commission to whose jurisdiction the Lender may be
subject, (d) to any rating agency to the extent required in connection with any
rating to be assigned to the Lender, (e) to assignees or participants or
prospective assignees or participants who agree to be bound by the provisions of

Agreement and the other Loan Documents or (g) with the Borrower's prior written
consent.

Re:   CREDIT AND SECURITY AGREEMENT DATED AS OF DECEMBER ___, 2002 (AS AMENDED
      FROM TIME TO TIME, THE "CREDIT AGREEMENT") AMONG SIGNAL TECHNOLOGY
      CORPORATION, AS BORROWER, SIGNAL TECHNOLOGY SALES CORPORATION, AS
      GUARANTOR, AND CITIZENS BANK OF MASSACHUSETTS, AS LENDER

Ladies & Gentlemen:

      Pursuant to Section 7.1 of the above-referenced Credit Agreement, enclosed
are copies of consolidated financial statements for the Borrower and its
Subsidiaries for the fiscal quarter ended ____________ (the "Fiscal Period"),
prepared in accordance with GAAP. Capitalized terms used but not defined herein
shall have the meanings set forth in the Credit Agreement.

      As required, a review of the activities of the Credit Parties during the
Fiscal Period has been made under the immediate supervision of the undersigned
with a view to determining whether, during the Fiscal Period, the Credit Parties
have kept, observed, performed and fulfilled each and every covenant and
condition of the Credit Agreement. To the best of my knowledge and belief there
neither exists on the date of this certificate, nor existed during the Fiscal
Period, any Default or Event of Default, except as set forth on any attachment
hereto. There has been no change in GAAP since the date of the last audited
financial statements delivered to you by the Credit Parties.

      As further required, attached are covenant calculations showing compliance
by the Borrower with the financial covenants set forth in Section 8.10 of the
Credit Agreement.

                                        Very truly yours,

bankruptcy laws, as now or hereafter constituted, or any other applicable
federal or state bankruptcy, insolvency or other similar law, and any other
interest that would have accrued but for the commencement of such proceeding,
whether or not any such interest is allowed as a claim enforceable against the
Pledgors in any such proceeding), all LC Disbursements and all other obligations
from time to time owing to the Lender by the Credit Parties under the Credit
Agreement or under any other Loan Document, and all obligations of the Borrower
to the Lender or any Affiliate of the Lender under any Hedging Agreement entered
into in connection with the Credit Agreement or any Loan Document, in each case
strictly in accordance with the terms thereof.

      4. SPECIAL WARRANTIES AND COVENANTS OF THE PLEDGORS. Each Pledgor hereby
warrants and covenants to the Lender with respect to the Pledged Collateral for
which it is the "Pledgor," as set forth on SCHEDULE I, that:

            (a) The Pledged Collateral is duly and validly pledged with the
Lender in accordance with law, the Lender has a First Priority security interest
in such Pledged Collateral, and each Pledgor warrants and will defend the
Lender's right, title and security interest in and to the Pledged Collateral
against the claims and demands of all Persons whomsoever.

            (b) Each Pledgor has good title to the Pledged Collateral, free and
clear of all Liens, except as expressly set forth in or permitted under the
Credit Agreement.

            (c) All of the Pledged Equity has been duly and validly issued and
is fully paid and nonassessable.

            (d) The Pledged Equity constitutes the amount and percentage of
partnership interests, limited liability company interests or shares, as
applicable, of the presently issued and outstanding partnership interests,
limited liability company interests or capital stock of the Listed Companies, as
applicable, as set forth on SCHEDULE I.

            (e) If any additional partnership interests, limited liability
company interests or shares of capital stock of any class of the Listed
Companies or if any promissory notes of the Listed Companies or other securities
of the Listed Companies are acquired by any Pledgor after the date hereof, the
same shall constitute Pledged Collateral and shall be deposited with and pledged
to the Lender as provided in Section 2 hereof simultaneously with such
acquisition. The Pledgors will promptly notify the Lender of the date and amount
of any loans made from time to time by the Pledgors to the Listed Companies as
permitted by the Credit Agreement.

            (f) No Pledgor will sell, convey or otherwise dispose of any of the
Pledged Collateral, nor will any Pledgor create, incur or permit to exist any
Lien with respect to any of the Pledged Collateral or the proceeds thereof,
other than Liens with respect to the Pledged Collateral created hereby and Liens
permitted under the Credit Agreement.

            (g) No Pledgor will consent to or approve the issuance of any
additional partnership interests, limited liability company interests or shares
of capital stock of any class of the Listed Companies, except for the issuance
of additional partnership interests, limited liability company interests or
shares of capital stock to such Pledgor as permitted by and in accordance with
the terms of the Credit

                                       2
<PAGE>

Agreement, provided that any such partnership interests, limited liability
company interests or additional shares of capital stock shall be deposited with
and pledged to the Lender simultaneously with such issuance as provided in
Section 2 hereof.

            (h) The Pledged Notes evidence the amount of outstanding
indebtedness for money borrowed of the respective issuers thereof indicated on
SCHEDULE I hereto.

            (i) If any additional promissory notes are acquired by any Pledgor
from the issuers of the Pledged Notes or any other Person, the same shall
constitute Pledged Notes and Pledged Collateral and shall be deposited with and
pledged to the Lender as provided in Section 2 hereof simultaneously with such
acquisition. The Pledgors will promptly notify the Lender of any loans made from
time to time to such issuers as permitted by the Credit Agreement.

      5. DISTRIBUTIONS. In case, upon the dissolution, winding up, liquidation
or reorganization of the Listed Companies whether in bankruptcy, insolvency or
receivership proceedings or upon an assignment for the benefit of creditors or
any other marshaling of the assets and liabilities of the Listed Companies or
otherwise, any sum shall be paid or any property shall be distributed upon or
with respect to any of the Pledged Collateral, such sum shall be paid over to
the Lender as collateral security for the Secured Obligations. In case any stock
dividend shall be declared on any of the Pledged Collateral, or any share of
stock or fraction thereof shall be issued pursuant to any stock split involving
any of the Pledged Collateral, or any distribution of capital or profits shall
be made on any of the Pledged Collateral, or any property shall be distributed
upon or with respect to the Pledged Collateral, the limited partnership
interests, limited liability company interests, shares, cash or other property
so distributed shall be delivered to the Lender as collateral security for the
Secured Obligations.

      6. EVENTS OF DEFAULT. The Pledgors shall be in default under this
Agreement upon the happening of any Event of Default, as defined in the Credit
Agreement (herein called an "Event of Default").

      7. RIGHTS AND REMEDIES OF LENDER. Upon the occurrence and during the
continuance of an Event of Default, the Lender shall have the following rights
and remedies:

            (a) All rights and remedies provided by law, including, without
limitation, those provided by the Uniform Commercial Code;

            (b) All rights and remedies provided in this Agreement; and

            (c) All rights and remedies provided in the Credit Agreement or in
the other Loan Documents, or in any other agreement, document or instrument
pertaining to the Secured Obligations.

      8. RIGHT TO TRANSFER INTO NAME OF LENDER, ETC. Upon the occurrence and
during the continuance of an Event of Default, but subject to the provisions of
the Uniform Commercial Code or other applicable law, the Lender may cause all or
any of the Pledged Collateral to be transferred into its name or into the name
of its nominee or nominees. So long as no Event of Default shall have occurred
and be continuing, each Pledgor shall be entitled to exercise as such Pledgor
shall deem fit, but in a manner not inconsistent with the terms hereof or of the
Secured Obligations, the voting power with respect to the Pledged Collateral.

      9. RIGHT OF LENDER TO EXERCISE VOTING POWER, ETC. Upon the occurrence and
during the continuance of an Event of Default, the Lender shall be entitled to
exercise the voting power with respect to the Pledged Collateral, to receive and
retain, as collateral security for the Secured Obligations, any and

                                       3
<PAGE>

all dividends or other distributions at any time and from time to time declared
or made upon any of the Pledged Collateral, and to exercise any and all rights
of payment, conversion, exchange, subscription or any other rights, privileges
or options pertaining to the Pledged Collateral as if it were the absolute owner
thereof, including, without limitation, the right to exchange, at its
discretion, any and all of the Pledged Collateral upon the merger,
consolidation, reorganization, recapitalization or other readjustment of the
Listed Companies or, upon the exercise of any such right, privilege or option
pertaining to the Pledged Collateral, and in connection therewith, to deposit
and deliver any and all of the Pledged Collateral with any committee,
depositary, transfer agent, registrar or other designated agency upon such terms
and conditions as the Lender may determine, all without liability except to
account for property actually received, but the Lender shall have no duty to
exercise any of the aforesaid rights, privileges or options and shall not be
responsible for any failure to do so or delay in so doing.

      10. RIGHT OF LENDER TO DISPOSE OF COLLATERAL, ETC. Upon the occurrence and
during the continuance of an Event of Default, the Lender shall have the right
at any time or times thereafter to sell, resell, assign and deliver all or any
of the Pledged Collateral in one or more parcels at any exchange or broker's
board or at public or private sale. Unless the Pledged Collateral is perishable
or threatens to decline speedily in value or is of a type customarily sold on a
recognized market, the Lender will give the Pledgors at least ten (10) days'
prior written notice in accordance with Section 20 hereof of the time and place
of any public sale thereof or of the time after which any private sale or any
other intended disposition of any of the Pledged Collateral is to be made. Any
such notice shall be deemed to meet any requirement hereunder or under any
applicable law (including the Uniform Commercial Code) that reasonable
notification be given of the time and place of such sale or other disposition.
Such notice may be given without any demand of performance or other demand, all
such demands being hereby expressly waived by each Pledgor. All such sales shall
be at such commercially reasonable price or prices as the Lender shall deem best
and either for cash or on credit or for future delivery (without assuming any
responsibility for credit risk). At any such sale or sales, the Lender may
purchase any or all of the Pledged Collateral to be sold thereat upon such terms
as the Lender may deem best. Upon any such sale or sales the Pledged Collateral
so purchased shall be held by the purchaser absolutely free from any claims or
rights of whatsoever kind or nature, including any equity of redemption and any
similar rights, all such equity of redemption and any similar rights being
hereby expressly waived and released by each Pledgor. In the event any consent,
approval or authorization of any governmental agency will be necessary to
effectuate any such sale or sales, each Pledgor shall execute, and hereby agrees
to cause the Listed Companies to execute, all such applications or other
instruments as may be required.

      Each Pledgor recognizes that the Lender may be unable to effect a public
sale of all or a part of the Pledged Collateral by reason of certain
prohibitions contained in the Securities Act of 1933, as amended (the
"Securities Act"), or otherwise but may be compelled to resort to one or more
private sales to a restricted group of purchasers, each of whom will be
obligated to agree, among other things, to acquire such Pledged Collateral for
its own account, for investment and not with a view to the distribution or
resale thereof. Each Pledgor acknowledges that private sales so made may be at
prices and upon other terms less favorable to the seller than if such Pledged
Collateral were sold at public sales without such restrictions, and that the
Lender has no obligation to delay sale of any such Pledged Collateral for the
period of time necessary to permit such Pledged Collateral to be registered for
public sale under the Securities Act. Each Pledgor agrees that any such private
sales shall not be deemed to have been made in a commercially unreasonable
manner solely because they shall have been made under the foregoing
circumstances.

      11. CREDIT AGREEMENT. Notwithstanding any other provision of this
Agreement, the rights of the parties hereunder are subject to the provisions of
the Credit Agreement, including the provisions thereof pertaining to the rights
and responsibilities of the Lender. In the event that any provision of this
Agreement is in conflict with the terms of the Credit Agreement, the Credit
Agreement shall control. The

                                       4
<PAGE>

term "Lender" as used herein shall include Citizens Bank of Massachusetts or any
other Person acting as Lender pursuant to the Credit Agreement.

      12. COLLECTION OF AMOUNTS PAYABLE ON ACCOUNT OF PLEDGED COLLATERAL, ETC.
Upon the occurrence and during the continuance of any Event of Default, the
Lender may, but without obligation to do so, demand, sue for and/or collect any
money or property at any time due, payable or receivable, to which it may be
entitled hereunder, on account of, or in exchange for, any of the Pledged
Collateral and shall have the right, for and in the name, place and stead of
each Pledgor, to execute endorsements, assignments or other instruments of
conveyance or transfer with respect to all or any of the Pledged Collateral.

      13. CARE OF PLEDGED COLLATERAL IN LENDER'S POSSESSION. Beyond the exercise
of reasonable care to assure the safe custody of the Pledged Collateral while
held hereunder, the Lender shall have no duty or liability to collect any sums
due in respect thereof or to protect or preserve rights pertaining thereto, and
shall be relieved of all responsibility for the Pledged Collateral upon
surrendering the same to the Pledgors.

      14. PROCEEDS OF COLLATERAL. The proceeds of any sale or sales of the
Pledged Collateral, together with any other additional collateral security at
the time received and held hereunder, shall be received and applied: first, to
the payment of all reasonable costs and expenses of such sale, including
reasonable attorneys' fees; second, to the payment of the Secured Obligations by
the Lender in accordance with the terms of the Credit Agreement; and third, any
surplus thereafter remaining shall be paid to the Pledgors or to whomever may be
legally entitled thereto (including, if applicable, any subordinated creditor of
the Listed Companies or the Pledgors). In the event the proceeds of any sale,
lease or other disposition of the Collateral hereunder are insufficient to pay
all of the Secured Obligations in full, each Pledgor will be liable for the
deficiency, together with interest thereon at the maximum rate provided in the
Credit Agreement, and the reasonable costs and expenses of collection of such
deficiency, including (to the extent permitted by law), without limitation,
reasonable attorneys' fees, expenses and disbursements.

      15. WAIVERS, ETC. Each Pledgor hereby waives presentment, demand, notice,
protest and, except as is otherwise provided herein or in the Credit Agreement,
all other demands and notices in connection with this Agreement or the
enforcement of the Lender's rights hereunder or in connection with any Secured
Obligations or any Pledged Collateral; consents to and waives notice (except as
specifically required by this Agreement or the Credit Agreement) of the granting
of renewals, extensions of time for payment or other indulgences to the Listed
Companies or the Pledgors or to any third party, or substitution, release or
surrender of any collateral security for any Secured Obligation, the addition or
release of Persons primarily or secondarily liable on any Secured Obligation or
on any collateral security for any Secured Obligation, the acceptance of partial
payments on any Secured Obligation or on any collateral security for any Secured
Obligation and/or the settlement or compromise thereof. No delay or omission on
the part of the Lender in exercising any right hereunder shall operate as a
waiver of such right or of any other right hereunder. Any waiver of any such
right on any one occasion shall not be construed as a bar to or waiver of any
such right on any future occasion. Each Pledgor further waives any right it may
have under the laws of the Commonwealth of Massachusetts, under the laws of any
state in which any of the Pledged Collateral may be located or which may govern
the Pledged Collateral, or under the laws of the United States of America, to
notice (other than any requirement of notice provided herein or in the Credit
Agreement) or to a judicial hearing prior to the exercise of any right or remedy
provided by this Agreement to the Lender and waives its rights, if any, to set
aside or invalidate any sale duly consummated in accordance with the foregoing
provisions hereof on the grounds (if such be the case) that the sale was
consummated without a prior judicial hearing. Each Pledgor's waivers under this
Section

                                       5
<PAGE>

have been made voluntarily, intelligently and knowingly and after such Pledgor
has been apprised and counseled by its attorneys as to the nature thereof and
its possible alternative rights.

      16. TERMINATION; ASSIGNMENT, ETC. When all the Secured Obligations have
been paid in full and have been terminated and the commitment of the Lender to
make any Loan under the Credit Agreement has terminated or expired and no
Letters of Credit remain outstanding, this Agreement and the security interest
in the Collateral created hereby shall terminate. No waiver by the Lender or by
any other holder of Secured Obligations of any default shall be effective unless
in writing nor operate as a waiver of any other default or of the same default
on a future occasion. In the event of a sale or assignment by the Lender of all
or any of the Secured Obligations held by it, the Lender may assign or transfer
its rights and interest under this Agreement in whole or in part to the
purchaser or purchasers of such Secured Obligations, whereupon such purchaser or
purchasers shall become vested with all of the powers and rights of the Lender
hereunder.

      17. REINSTATEMENT. Notwithstanding the provisions of Section 16, this
Agreement shall continue to be effective or be reinstated, as the case may be,
if at any time any amount received by the Lender in respect of the Secured
Obligations is rescinded or must otherwise be restored or returned by the Lender
upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of
any of the Listed Companies, any Pledgor or upon the appointment of any
intervener or conservator of, or trustee or similar official for, the Listed
Companies or any Pledgor, or any substantial part of their respective
properties, or otherwise, all as though such payments had not been made.

      18. GOVERNMENTAL APPROVALS, ETC. Upon the exercise by the Lender of any
power, right, privilege or remedy pursuant to this Agreement which requires any
consent, approval, qualification or authorization of any governmental authority
or instrumentality, each Pledgor will execute and deliver, or will cause the
execution and delivery of, all applications, certificates, instruments and other
documents and papers that the Lender may be required to obtain for such
governmental consent, approval, qualification or authorization.

      19. RESTRICTIONS ON TRANSFER, ETC. To the extent that any restrictions
imposed by the charter, certificate of limited partnership, limited partnership
agreement, operating agreement or by-laws of any of the Listed Companies or any
other document or instrument would in any way affect or impair the pledge of the
Pledged Collateral hereunder or the exercise by the Lender of any right granted
hereunder, including, without limitation, the right of the Lender to dispose of
the Pledged Collateral upon the occurrence and during the continuance of an
Event of Default, each Pledgor hereby waives such restrictions, and represents
and warrants that it has caused the Listed Companies to take all necessary
action to waive such restrictions, and each Pledgor hereby agrees that it will
take any further action which the Lender may reasonably request in order that
the Lender may obtain and enjoy the full rights and benefits granted to the
Lender by this Agreement free of any such restrictions.

      20. NOTICES. All notices, consents, approvals, elections and other
communications hereunder shall be in writing (whether or not the other
provisions of this Agreement expressly so provide) and shall be deemed to have
been duly given if delivered in accordance with the terms of Section 10.1 of the
Credit Agreement.

      21. MISCELLANEOUS. This Agreement shall inure to the benefit of and be
binding upon the Lender and each Pledgor and their respective successors and
assigns, and the term "Lender " shall be deemed to include any other holder or
holders of any of the Secured Obligations. In case any provision in this
Agreement shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby. This Agreement may be

                                       6
<PAGE>

executed in any number of counterparts and by the different parties hereto on
separate counterparts, each of which shall be an original, but all of which
together shall constitute one instrument.

      22. GOVERNING LAW; JURISDICTION; WAIVER OF JURY TRIAL. This Agreement,
including the validity hereof and the rights and obligations of the parties
hereunder, shall be construed in accordance with and governed by the laws of the
Commonwealth of Massachusetts. Each Pledgor, to the extent that it may lawfully
do so, hereby consents to service of process, and to be sued, in the
Commonwealth of Massachusetts and consents to the jurisdiction of the courts of
the Commonwealth of Massachusetts and the United States District Court for the
District of Massachusetts, as well as to the jurisdiction of all courts to which
an appeal may be taken from such courts, for the purpose of any suit, action or
other proceeding arising out of any of its obligations hereunder or with respect
to the transactions contemplated hereby, and expressly waives any and all
objections it may have as to venue in any such courts. Each Pledgor further
agrees that a summons and complaint commencing an action or proceeding in any of
such courts shall be properly served and shall confer personal jurisdiction if
served personally or by certified mail to it in accordance with Section 20
hereof or as otherwise provided under the laws of the Commonwealth of
Massachusetts. Nothing in this Agreement shall affect any right the Lender may
otherwise have to bring an action or proceeding relating to this Agreement
against any Pledgor or its properties in the courts of any jurisdiction. EACH
PLEDGOR IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY SUIT, ACTION OR
OTHER PROCEEDING INSTITUTED BY OR AGAINST SUCH PLEDGOR IN RESPECT OF ITS
OBLIGATIONS HEREUNDER OR THE TRANSACTIONS CONTEMPLATED HEREBY.

                                       7

instrument as of the date first above written.

                               HAZARDOUS MATERIALS
                               INDEMNITY AGREEMENT

      THIS HAZARDOUS MATERIALS INDEMNITY AGREEMENT (the "Agreement") is entered
into as of __________ __, 2002, by the undersigned (hereinafter referred to
collectively as the "Indemnitors"), in favor of CITIZENS BANK OF MASSACHUSETTS
(the "Lender") with a place of business at Exchange Place, 53 State Street,
Boston, Massachusetts 02109.

      Reference is made to the following facts:

      A. The Indemnitors have entered into a Credit and Security Agreement dated
as of the date hereof (as amended from time to time, the "Credit Agreement")
with the Lender, pursuant to which the Lender has agreed, subject to the terms
and conditions set forth therein, to make certain Loans as defined in the Credit
Agreement (the "Loans") to Signal Technology Corporation (the "Borrower").
Except as otherwise expressly defined herein or in the exhibits attached hereto,
all capitalized terms shall have the meanings ascribed to them in the Credit
Agreement.

      B. As a condition to making the Loans and issuing Letters of Credit, the
Lender requires that the Indemnitors agree to indemnify and hold harmless the
Lender from any Environmental Claim, any Requirements of Environmental Law, and
any violation of any Environmental Permit, and all Costs (as the foregoing terms
are defined in Exhibit A hereto) relating to the Premises (as hereinafter
defined). The Lender would not make the Loans or issue the Letters of Credit
without this Agreement and Indemnitors acknowledge and understand that this
Agreement is a material inducement for the Lender's agreement to make the Loans
and issue the Letters of Credit.

      C. Certain of the Indemnitors are the owners of certain of the parcels
described as "Owned Properties" on the attached Exhibit B and are hereinafter
referred to as the "Premises".

      NOW, THEREFORE, in consideration of the Lender's agreement to make the
Loans and issue the Letters of Credit and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
Indemnitors hereby covenant and agree as follows:

      1. Hazardous Materials; Compliance with Requirements of Environmental Law.

      Except as disclosed on Exhibit C,

            (a) The Indemnitors represent and warrant that they have never
generated, stored (other than the lawful storage of heating oil in amounts
required for the heating of buildings located on the Premises, or other than the
handling of Hazardous Materials in the Indemnitors' ordinary course of business
in material compliance with the Requirements of Environmental Law), or disposed
of any Hazardous Materials on the Premises except in compliance with the
Requirements of Environmental Law, and the Indemnitors are not aware of the
generation, storage, disposal or release of Hazardous Materials on the Premises
by any other

<PAGE>

person, or the generation, storage, disposal or release of Hazardous Materials
upon or into the real property adjoining or in the vicinity of the Premises
which through soil or ground water migration could have come to be located at
the Premises. The Indemnitors further represent and warrant to the best of their
knowledge that there are no underground storage tanks on the Premises except as
disclosed to the Lender in writing. The Indemnitors agree not to release or
dispose of any Hazardous Materials at the Premises, nor to permit the same, at
any time during the term of the Loans in violation of the Requirements of
Environmental Law.

            (b) The Indemnitors represent and warrant that the Premises
materially comply with all applicable Requirements of Environmental Law. The
Indemnitors covenant that the Premises and the Indemnitors, and each Subsidary
thereof (as that term is defined in the Credit Agreement), shall at all times
comply in all material respects with all Requirements of Environmental Law.

            (c) The Lender may (but shall not be obligated to), from time to
time during the term of the Loans, for reasonable cause, and at the Indemnitors'
expense, cause Indemnitors to conduct such investigations as the Lender deems
reasonable to determine whether Hazardous Materials exist on any part of the
Premises and to determine the source, quantity and type of such Hazardous
Materials, if any. Such investigations may include without limitation a detailed
visual inspection of the Premises, including all storage areas, storage tanks,
drains and dry wells, as well as the taking of soil samples, surface water
samples, and ground water samples and such other investigations or analyses as
are reasonably necessary or appropriate in the Lender's sole discretion for a
complete assessment of the compliance of the Premises and the use and operation
thereof with all Requirements of Environmental Law. In the event the Indemnitors
shall fail to conduct such investigations, the Lender may, but shall not be
required to, cause such investigations to be performed and all associated Costs
shall become an Environmental Claim hereunder. In such an event, the Lender and
its officers, employees, agents and contractors shall have and are hereby
granted the right to enter upon the Premises for the foregoing purposes,

Indemnitors of each such entry and shall use reasonable efforts to minimize the
disruption to the operation of the Indemnitors' business on the Premises.

            (d) Without limiting the generality of this Section, during the term
of the Indemnitors' ownership, leasing, operation or use of the Premises, the
Indemnitors, and the Premises and all alterations thereof, shall comply in all
material respects with all local, state and federal laws and regulations now or
hereafter in effect and applicable relating to the presence, abatement, removal,
disposal, transportation or treatment of materials containing asbestos.

            (e) Without limiting the generality of this Section, during the term
of the Indemnitors' ownership, leasing, operation or use of the Premises, if any
portion of the Premises is to be used for residential purposes, the Premises and
all alterations thereof shall comply in all material respects with all local,
state and federal laws and regulations now or hereafter in effect and applicable

harmless the Lender, each Affiliate of the Lender, each Related Party of the

entities being referred to herein individually as an "Indemnitee" and
collectively as "Indemnitees") from and against all Costs which at any time may

them, with respect to the Premises or the Indemnitors' ownership, use,
occupation or operation thereof and thereon and arising out of or in connection
with (i) Requirements of Environmental Law; (ii) Environmental Claims; (iii) the
failure of the Indemnitors, or any other party directly or indirectly connected
with the Premises, or affiliated with Indemnitors having any control over or
responsibility for the use and operation of the Premises, to obtain, maintain,
or comply with any Environmental Permit; and/or (iv) the presence, existence or
threat of release of Hazardous Materials (as defined in Exhibit A hereto) at,
on, about, under, within or in connection with the Premises, in all cases
excepting those Costs which are determined by a court of competent jurisdiction
by final and nonappealable judgment to have resulted from (A) the gross
negligence or willful misconduct of Indemnitees or (B) a release or threat of
release of Hazardous Materials originating during the period of time that the
Lender controls and occupies the Premises by assignment, deed-in-lieu of

            (b) In the event that any Remedial Work (as defined in Exhibit A

governmental or non-governmental entity or person because of, or in connection
with, the current or future presence, suspected presence, release or suspected
release or threat of release of Hazardous Materials in or into the air, soil,
ground water, surface water or soil vapor at, on, about, under, within, near,

misconduct of Indemnitees, shall be paid by Indemnitors including, without
limitation, reasonable Costs incurred by any Indemnitee in connection with the
monitoring or review of such Remedial Work by the Indemnitee or a third party
engaged by Indemnitee. In the event the Indemnitors shall fail to commence, or
cause to be commenced, or fail to prosecute to completion, such Remedial Work in
compliance with the Requirements of Environmental Law, the Lender may, but shall
not be required to, cause such Remedial Work to be performed and all Costs shall
become an Environmental Claim hereunder.

survive (i) repayment of the Loans; (ii) satisfaction, assignment or

and the Premises and (vii) termination of any of the Leases.

            (d) Nothing contained in this Agreement shall prevent or in any way
diminish or interfere with any rights or remedies, including, without
limitation, the right to contribution, which any Indemnitee may have against the

Premises; (iii) any actual or alleged material violation of any Requirements of
Environmental Law of which it has knowledge; (iv) notice of any actual or
alleged Environmental Claim of which it has knowledge; (v) the discovery by

transferability, or use, or subject the owner or any person having any interest
in the Premises to any liability, penalty, or disability under any Requirements
of Environmental Law; (vi) the receipt of any notice or discovery of any
information regarding any actual, alleged, or potential spillage, seepage,
release, discharge, disposal or any other presence or existence of any Hazardous
Material at, on, about, under, within, adjoining, in the vicinity of or in

      4. Procedures Relating to Indemnification.

            (a) In any circumstance in which this Agreement applies, the Lender
may, but shall not be obligated to, employ its own legal counsel and consultants
to investigate, prosecute, negotiate, or defend any such Environmental Claim and
in the event liability is asserted directly against the Lender, the Lender shall
have the right to compromise or settle such claim of liability against the
Lender without the consent of Indemnitors. Indemnitors shall reimburse the
Lender, within fifteen (15) days of demand, for all Costs incurred by the
Lender, including the amount of all Costs of settlements entered into by the
Lender, in all cases excepting those Costs which are

                                       4
<PAGE>

determined by a court of competent jurisdiction by final and nonappealable
judgment to have resulted from the gross negligence or willful misconduct of
Indemnitees or their agents, employees or contractors,.

            (b) The Indemnitors shall not, without the prior written consent of
the Lender (i) settle or compromise any action, suit, proceeding, or claim or
consent to the entry of any judgment that does not include as an unconditional
term thereof the delivery by the claimant or plaintiff to the Lender of (x) a
full and complete written release of the Lender from all liability in respect of
such action, suit or proceeding and (y) a dismissal with prejudice of such suit,
action or proceeding; or (ii) settle or compromise any action, suit, proceeding,
or claim in any manner that may adversely affect the Lender as determined by the
Lender in its reasonable discretion.

      5. Binding Effect. This Agreement shall be binding upon the Indemnitors,
their successors and permitted assigns and shall inure to the benefit of the
Indemnitees and their respective successors and assigns, including as to the
Lender without limitation, any affiliate of the Lender which acquires all or
part of the Premises by any sale, assignment, assignment or deed in lieu of
foreclosure or other enforcement, or foreclosure under the Mortgages, or
otherwise. The obligations of Indemnitors under this Agreement shall not be
assigned without the prior written consent of the Lender, which consent may be
given or withheld in the sole discretion of the Lender.

      6. Liability of Indemnitors. The liability of each party comprising the
Indemnitors shall be joint and several. The liability of Indemnitors under this
Agreement shall in no way be limited or impaired by the provisions of any of the
Loan Documents, or any amendment, modification, extension or renewal thereof. No
delay on the Lender's part in acting under this Indemnity shall operate as a
waiver of any of the Lender's rights hereunder. No waiver hereunder by the
Lender in any instance shall constitute a waiver in any other instance.

      7. Waiver. The Indemnitors waive any right or claim of right to cause a
marshalling of the assets of the Indemnitors or to cause the Lender to proceed
against any of the security for the Loans before proceeding under this Agreement
against the Indemnitors; the Indemnitors agree that any payments required to be
made hereunder shall become due on demand; to the extent permitted by applicable
law, the Indemnitors expressly agree that the liability of the Indemnitors
hereunder shall in no way be affected by: (a) the release or discharge of any
Indemnitor in any creditors', receivership, bankruptcy or other proceedings; (b)
the impairment, limitation or modification of the liability of any Indemnitor or
the estate of any Indemnitor in bankruptcy, or of any remedy for the enforcement
of any Indemnitor's liability under the Loan Documents, resulting from the
operation of any present or future provision of the Bankruptcy Code, 11 U.S.C.
ss. 101 ET SEQ. or other similar statute or from the decision in any court; (c)
the rejection or disaffirmance of the Loan Documents in any such proceedings;
(d) the assignment or transfer of the Loan Documents by the Indemnitors; (e) any
disability or other defense of any Indemnitor; or (f) the cessation from any
cause whatsoever for the liability of any Indemnitor. Without limiting the
generality of the foregoing, the Indemnitors hereby waive all suretyship
defenses or defenses in the nature thereof.

      8. Notices. All notices, consents, approvals, elections and other
communications (collectively "Notices") hereunder shall be in writing (whether
or not the other provisions of this Agreement expressly so provide) and shall be
deemed to have been duly given if delivered in accordance with the terms of the
Credit Agreement.

                                       5
<PAGE>

      9. Attorneys' Fees. In the event that any Indemnitee brings or otherwise
becomes a party to any suit or other proceeding (including, without limitation,
any administrative proceedings, but excluding any suit brought by any Indemnitee
which is ruled to be frivolous or brought in bad faith) with respect to the
subject matter or enforcement of this Agreement, such Indemnitee shall, in
addition to such other relief as may be awarded, be entitled to recover from
Indemnitors attorneys' fees, expenses and costs of investigation as are actually
incurred (including, without limitation, reasonable attorneys' fees, expenses
and costs of investigation incurred in appellate proceedings, costs incurred in
establishing the right to indemnification, or in any action or participation in,
or in connection with, any case or proceeding under Chapter 7, 11 or 13 of the
Bankruptcy Code, 11 U.S.C.Section 101 et seq., or any successor statutes).

      10. Governing Law. This Agreement, including the validity hereof and the
rights and obligations of the parties hereunder, shall in all respects be
governed by, and construed and enforced in accordance with the laws of the
Commonwealth of Massachusetts. Each Indemnitor, to the extent that it may
lawfully do so, hereby consents to service of process, and to be sued, in the
Commonwealth of Massachusetts and consents to the jurisdiction of the courts of
the Commonwealth of Massachusetts and the United States District Court for the
District of Massachusetts, as well as to the jurisdiction of all courts to which
an appeal may be taken from such courts, for the purpose of any suit, action or
other proceeding arising out of any of its obligations hereunder or with respect
to the transactions contemplated hereby, and expressly waives any and all
objections it may have as to venue in any such courts. Each Indemnitor further
agrees that a summons and complaint commencing a suit, action or proceeding in
any of such courts shall be properly served and shall confer personal
jurisdiction if served personally or by certified mail in accordance with the
terms of the Credit Agreement or as otherwise provided under the laws of the
Commonwealth of Massachusetts. Nothing in this Agreement shall affect any right
the Lender or any Indemnitee may otherwise have to bring an action or proceeding
relating to this Agreement against any Indemnitor or its properties in the
courts of any jurisdiction.

      11. Successive Actions. A separate right of action hereunder shall arise
each time the Lender acquires knowledge of any matter indemnified by Indemnitors
under this Agreement. Separate and successive actions may be brought hereunder
to enforce any of the provisions hereof at any time and from time to time. No
action hereunder shall preclude any subsequent action, and Indemnitors hereby
waive and covenant not to assert any defense in the nature of splitting of
causes of action or merger of judgments.

      12. Partial Invalidity. If any provision of this Agreement shall be
determined to be unenforceable in any circumstances by a court of competent
jurisdiction, then the balance of this Agreement shall be enforceable
nonetheless, and the subject provision shall be enforceable in all other
circumstances.

      13. Interest on Unpaid Amounts. All amounts required to be paid or
reimbursed to any Indemnitee hereunder shall bear interest from the date of
expenditure by such Indemnitee or the date of written demand to Indemnitors
hereunder, whichever is later, until paid to Indemnitee(s). The interest rate
shall be the lesser of (a) the maximum rate provided for in the Credit Agreement
or (b) the maximum rate then permitted for the parties to contract for under
applicable law.

      14. Authority. Each individual signing this Indemnity Agreement on behalf
of the

                                       6
<PAGE>

Indemnitors or any other indemnitor which is not a natural person warrants and
represents to the Lender that he or she is authorized to do so by all requisite
action of the Indemnitors or such other entity.

      15. Credit Agreement. To the extent that any provision of this Indemnity
Agreement conflicts with any provision of the Credit Agreement with respect to
the matters contained in this Indemnity Agreement, this Indemnity Agreement
shall control.
