           (4) "Beneficiary" means the person or persons entitled under Section

           the course of the employers trade or business) for which the employer

           (14)  "Hour of Service" means, with respect to any Employee,

                 (A) Each hour for which the Employee is directly or indirectly
                 paid, or entitled to payment, for the performance of duties for
                 the Employer or a Related Employer, each such hour to be
                 credited to the Employee for the computation period in which
                 the duties were performed;

                 (B) Each hour for which the Employee is directly or indirectly
                 paid, or entitled to payment, by the Employer or Related
                 Employer (including payments made or due from a trust fund or
                 insurer to which the Employer contributes or pays premiums) on
                 account of a period of time during which no duties are
                 performed (irrespective of whether the employ-ment relationship
                 has terminated) due to vacation, holiday, illness, incapacity,
                 disability, layoff, jury duty, military duty, or leave of
                 absence, each such hour to be credited to the Employee for the

                 occurs, subject to the following rules:

                      (i) No more than 501 Hours of Service shall be credited
                      under this paragraph (B) on account of any single
                      contin-uous period during which the Employee performs no
                      duties;

                                       2
<PAGE>   7

                      (ii) Hours of Service shall not be credited under this
                      paragraph (B) for a payment which solely reimburses the
                      Employee for medically-related expenses, or which is made
                      or due under a plan maintained solely for the purpose of
                      complying with applicable workmen's compensation,
                      unemployment compensation or disability insurance laws;
                      and

                      (iii) If the period during which the Employee performs no
                      duties falls within two or more computation periods and if
                      the payment made on account of such period is not
                      calculated on the basis of units of time, the Hours of
                      Service credited with respect to such period shall be
                      allocated between not more than the first two such
                      computation periods on any reasonable basis consistently
                      applied with respect to similarly situated Employees; and

                 (C) Each hour not counted under paragraph (A) or (B) for which
                 back pay, irrespective of mitigation of damages, has been
                 either awarded or agreed to be paid by the Employer or a
                 Related Employer, each such hour to be credited to the Employee
                 for the computation period to which the award or agreement
                 pertains rather than the computation period in which the award
                 agreement or payment is made.

                     For purposes of determining Hours of Service, Employees of
                 the Employer and of all Related Employers will be treated as
                 employed by a single employer. For purposes of paragraphs (B)
                 and (C) above, Hours of Service will be calculated in
                 accordance with the provisions of Section 2530.200b-2(b) of the
                 Department of Labor regulations which are incorporated herein
                 by reference.

                     Solely for purposes of determining whether a break in
                 service for participation purposes has occurred in a
                 computation period, an individual who is absent from work for
                 maternity or paternity reasons shall receive credit for the
                 hours of service which would otherwise been credited to such
                 individual but for such absence, or in any case in which such
                 hours cannot be determined, 8 hours of service per day of such
                 absence. For purposes of this paragraph, an absence from work
                 for maternity reasons means an absence (1) by reason of the
                 pregnancy of the individual, (2) by reason of a birth of a
                 child of the individual, (3) by reason of the placement of a
                 child with the individual in connection with the adoption of
                 such child by such individual, or (4) for purposes of caring
                 for such child for a period beginning immediately following
                 such birth or placement. The hours of service credited under
                 this paragraph shall be credited (1) in the computation period
                 in which the absence begins if the crediting is necessary to
                 prevent a break in service in that period, or (2) in all other
                 cases, in the following computation period.

       (15) "Normal Retirement Age" means the normal retirement age specified in
       Section 1.06(a) of the Adoption Agreement.

       (16) "Owner-Employee" means, if the Employer is a sole proprietorship,
       the individual who is the sole proprietor, or if the Employer is a
       partnership, a partner who owns more than 10 percent of either the
       capital interest or the profits interest of the partnership.

                                       3

       accordance with Article 3 hereof.

       (18) "Plan" means the plan established by the Employer as set forth
       herein as a new plan or as an amendment to an existing plan, by executing
       the Adoption Agreement, together with any and all amendments hereto.

       (19) "Plan Year" means the 12-consecutive month period designated by the
       Employer in Section 1.01(d).

       (20) "Registered Investment Company" means any one or more corporations,
       partnerships or trusts registered under the Investment Company Act of
       1940 for which Fidelity Management and Research Company serves as
       investment advisor.

       (21) "Related Employer" means any employer other than the Employer named
       in Section 1.02(a), if the Employer and such other employer are members
       of a controlled group of corporations (as defined in Section 414(b) of
       the Code) or an affiliated service group (as defined in Section 414(m)),
       or are trades or businesses (whether or not incorporated) which are under
       common control (as defined in Section 414(c)), or such other employer is
       required to be aggregated with the Employer pursuant to regulations
       issued under Section 414(o).

       (22) "Self-Employed Individual" means an individual who has Earned Income
       for the taxable year from the Employer or who would have had Earned
       Income but for the fact that the trade or business had no net profits for
       the taxable year.

       (23)  "Trust" means the trust created by the Employer.

       (24) "Trust Agreement" means the agreement between the Employer and the
       Trustee, as set forth in a separate agreement, under which assets are
       held, administered, and managed subject to the claims of the Employer's
       creditors in the event of the Employer's insolvency, until paid to Plan
       Participants and their Beneficiaries as specified in the Plan.

       (25)  "Trust Fund" means the property held in the Trust by the Trustee.

       (26) "Trustee" means the corporation or individuals appointed by the
       Employer to administer the Trust in accordance with the Trust Agreement.

       (27) "Years of Service for Vesting" means, with respect to any Employee,
       the number of whole years of his periods of service with the Employer or
       a Related Employer (the elapsed time method to compute vesting service),
       subject to any exclusions elected by the Employer in Section 1.07(b). An
       Employee will receive credit for the aggregate of all time period(s)
       commencing with the Employee's Employment Commencement Date and ending on
       the date a break in service begins, unless any such years are excluded by
       Section 1.07(b). An Employee will also receive credit for any period of
       severance of less than 12 consecutive months. Fractional periods of a
       year will be expressed in terms of days.

                                       4
<PAGE>   9

             In the case of a Participant who has 5 consecutive 1-year breaks in
       service, all years of service after such breaks in service will be
       disregarded for the purpose of vesting the Employer-derived account
       balance that accrued before such breaks, but both pre-break and
       post-break service will count for the purposes of vesting the
       Employer-derived account balance that accrues after such breaks. Both
       accounts will share in the earnings and losses of the fund.

             In the case of a Participant who does not have 5 consecutive 1-year
       breaks in service, both the pre-break and post-break service will count
       in vesting both the pre-break and post-break employer-derived account
       balance.

             A break in service is a period of severance of at least 12
       consecutive months. Period of severance is a continuous period of time
       during which the Employee is not employed by the Employer. Such period
       begins on the date the Employee retires, quits or is discharged, or if
       earlier, the 12 month anniversary of the date on which the Employee was
       otherwise first absent from service.

             In the case of an individual who is absent from work for maternity
       or paternity reasons, the 12-consecutive month period beginning on the
       first anniversary of the first date of such absence shall not constitute
       a break in service. For purposes of this paragraph, an absence from work
       for maternity or paternity reasons means an absence (1) by reason of the
       pregnancy of the individual, (2) by reason of the birth of a child of the
       individual, (3) by reason of the placement of a child with the individual
       in connection with the adoption of such child by such individual, or (4)
       for purposes of caring for such child for a period beginning immediately
       following such birth or placement.

             If the Plan maintained by the Employer is the plan of a predecessor
       employer, an Employee's Years of Service for Vesting shall include years
       of service with such predecessor employer. In any case in which the Plan
       maintained by the Employer is not the plan maintained by a predecessor
       employer, service for such predecessor shall be treated as service for
       the Employer to the extent provided in Section 1.08.

(b) Pronouns used in the Plan are in the masculine gender but include the
feminine gender unless the context clearly indicates otherwise.

ARTICLE 3.  PARTICIPATION.

3.01. DATE OF PARTICIPATION. An eligible Employee (as set forth in Section
1.03(a)) will become a Participant in the Plan on the first Entry Date after
which he becomes an eligible Employee if he has filed an election pursuant to
Section 4.01. If the eligible Employee does not file an election pursuant to
Section 4.01 prior to his first Entry Date, then the eligible Employee will
become a Participant in the Plan as of the first day of a Plan Year for which he
has filed an election.

3.02. RESUMPTION OF PARTICIPATION FOLLOWING RE EMPLOYMENT. If a Participant
ceases to be an Employee and thereafter returns to the employ of the Employer he
will again become a Participant as of an Entry Date following the date on which
he completes an Hour of Service for the Employer following his re employment, if
he is an eligible Employee as defined in Section 1.03(a), and has filed an
election pursuant to Section 4.01.

                                       5
<PAGE>   10

3.03. CESSATION OR RESUMPTION OF PARTICIPATION FOLLOWING A CHANGE IN STATUS. If
any Participant continues in the employ of the Employer or Related Employer but
ceases to be an eligible Employee as defined in Section 1.03(a), the individual
shall continue to be a Participant until the entire amount of his benefit is
distributed; however, the individual shall not be entitled to make Deferral
Contributions or receive an allocation of Matching contributions during the
period that he is not an eligible Employee. Such Participant shall continue to
receive credit for service completed during the period for purposes of
determining his vested interest in his Accounts. In the event that the
individual subsequently again becomes an eligible Employee, the individual shall
resume full participation in accordance with Section 3.01.

ARTICLE 4.  CONTRIBUTIONS.

4.01. DEFERRAL CONTRIBUTIONS. Each Participant may elect to execute a salary
reduction agreement with the Employer to reduce his Compensation by a specified
percentage not exceeding the percentage set forth in Section 1.05(a) and equal
to a whole number multiple of one (1) percent. Such agreement shall become
effective on the first day of the period as set forth in the Participant's
election. The election will be effective to defer Compensation relating to all
services performed in a Plan Year subsequent to the filing of such an election.
An election once made will remain in effect until a new election is made. A new
election will be effective as of the first day of the following Plan Year and
will apply only to Compensation payable with respect to services rendered after
such date. Amounts credited to a Participant's account prior to the effective
date of any new election will not be affected and will be paid in accordance
with that prior election. The Employer shall credit an amount to the account
maintained on behalf of the Participant corresponding to the amount of said
reduction. Under no circumstances may a salary reduction agreement be adopted
retroactively. A Participant may not revoke a salary reduction agreement for a
Plan year during that year.

4.02. MATCHING CONTRIBUTIONS. If so provided by the Employer in Section 1.05(b),
the Employer shall make a Matching Contribution to be credited to the account
maintained on behalf of each Participant who had Deferral Contributions made on
his behalf during the year and who meets the requirement, if any, of Section
1.05(b)(3). The amount of the Matching Contribution shall be determined in
accordance with Section 1.05(b).

4.03. TIME OF MAKING EMPLOYER CONTRIBUTIONS. The Employer will from time to time

5.01. INDIVIDUAL ACCOUNTS. The Administrator will establish and maintain an
Account for each Participant which will reflect Matching and Deferral
Contributions credited to the Account on behalf of the Participant and earnings,
expenses, gains and losses credited thereto, and deemed investments made with
amounts in the Participant's Account. The Administrator will establish and
maintain such other accounts and records as it decides in its discretion to be
reasonably required or appropriate in order to discharge its duties under the
Plan. Participants will be furnished statements of their Account values at least
once each Plan Year.

ARTICLE 6.  INVESTMENT OF CONTRIBUTIONS.

6.01. MANNER OF INVESTMENT. All amounts credited to the Accounts of Participants
shall be treated as though invested and reinvested only in eligible investments
selected by the Employer in Section 1.11(b).

6.02. INVESTMENT DECISIONS. Investments in which the Accounts of Participants
shall be treated as invested and reinvested shall be directed by the Employer or
by each Participant, or both, in accordance with the Employer's election in
Section 1.11(a).

        (a) All dividends, interest, gains and distributions of any nature
        earned in respect of Fund Shares in which the Account is treated as
        investing shall be credited to the Account as though reinvested in
        additional shares of that Fidelity Fund.

        (b) Expenses attributable to the acquisition of investments shall be
        charged to the Account of the Participant for which such investment is
        made.

ARTICLE 7.  RIGHT TO BENEFITS.

7.01. NORMAL OR EARLY RETIREMENT. If provided by the Employer in Section
1.07(d), each Participant who attains his Normal Retirement Age or Early
Retirement Age will have a nonforfeitable interest in his Account in accordance
with the vesting schedule elected in Section 1.07. If a Participant retires on
or after attainment of Normal or Early Retirement Age, such retirement is
referred to as a normal retirement. On or after his normal retirement, the
balance of the Participant's Account, plus any amounts thereafter credited to
his Account, subject to the provisions of Section 7.06, will be distributed to
him in accordance with Article 8.

       If provided by the Employer in Section 1.06, a Participant who separates
from service before satisfying the age requirements for early retirement, but
has satisfied the service requirement will be entitled to the distribution of
his Account, subject to the provisions of Section 7.06, in accordance with
Article 8, upon satisfaction of such age requirement.

7.02. DEATH. If a Participant dies before the distribution of his Account has
commenced, or before such distribution has been completed, his Account shall
become vested in accordance with the vesting schedule elected in Section 1.07
and his designated Beneficiary or Beneficiaries will be entitled to receive the
balance or remaining balance of his Account, plus any amounts thereafter
credited to his Account, subject to the provisions of Section 7.06. Distribution
to the Beneficiary or Beneficiaries will be made in accordance with Article 8.

        A Participant may designate a Beneficiary or Beneficiaries, or change
any prior designation of Beneficiary or Beneficiaries by giving notice to the
Administrator on a form designated by the Administrator. If more than one person
is designated as the Beneficiary, their respective interests shall be as
indicated on the designation form.

                                       7
<PAGE>   12

        A copy of the death notice or other sufficient documentation must be
filed with and approved by the Administrator. If upon the death of the
Participant there is, in the opinion of the Administrator, no designated
Beneficiary for part or all of the Participant's Account, such amount will be
paid to his surviving spouse or, if none, to his estate (such spouse or estate
shall be deemed to be the Beneficiary for purposes of the Plan). If a
Beneficiary dies after benefits to such Beneficiary have commenced, but before
they have been completed, and, in the opinion of the Administrator, no person
has been designated to receive such remaining benefits, then such benefits shall
be paid to the deceased Beneficiary's estate.

7.03. OTHER TERMINATION OF EMPLOYMENT. If provided by the Employer in Section
1.06, if a Participant terminates his employment for any reason other than death
or normal retirement, he will be entitled to a termination benefit equal to (i)
the vested percentage(s) of the value of the Matching Contributions to his
Account, as adjusted for income, expense, gain, or loss, such percentage(s)
determined in accordance with the vesting schedule(s) selected by the Employer
in Section 1.07, and (ii) the value of the Deferral Contributions to his Account
as adjusted for income, expense, gain or loss. The amount payable under this
Section 7.03 will be subject to the provisions of Section 7.06 and will be
distributed in accordance with Article 8.

7.04. SEPARATE ACCOUNT. If a distribution from a Participant's Account has been
made to him at a time when he has a nonforfeitable right to less than 100
percent of his Account, the vesting schedule in Section 1.07 will thereafter
apply only to amounts in his Account attributable to Matching Contributions
allocated after such distribution. The balance of his Account immediately after
such distribution will be transferred to a separate account which will be
maintained for the purpose of determining his interest therein according to the
following provisions.

       At any relevant time prior to a forfeiture of any portion thereof under
Section 7.05, a Participant's nonforfeitable interest in his Account held in a
separate account described in the preceding paragraph will be equal to P(AB +
(RxD))-(RxD), where P is the nonforfeitable percentage at the relevant time
determined under Section 7.05; AB is the account balance of the separate account
at the relevant time; D is the amount of the distribution; and R is the ratio of
the account balance at the relevant time to the account balance after
distribution. Following a forfeiture of any portion of such separate account
under Section 7.05 below, any balance in the Participant's separate account will
remain fully vested and nonforfeitable.

7.05. FORFEITURES. If a Participant terminates his employment, any portion of
his Account (including any amounts credited after his termination of employment)
not payable to him under Section 7.03 will be forfeited by him. For purposes of
this paragraph, if the value of a Participant's vested account balance is zero,
the Participant shall be deemed to have received a distribution of his vested
interest immediately following termination of employment. Such forfeitures will
be applied to reduce the contributions of the Employer under the Plan (or
administrative expenses of the Plan).

                                       8
<PAGE>   13

7.06. ADJUSTMENT FOR INVESTMENT EXPERIENCE. If any distribution under this
Article 7 is not made in a single payment, the amount remaining in the Account
after the distribution will be subject to adjustment until distributed to
reflect the income and gain or loss on the investments in which such amount is
treated as invested and any expenses properly charged under the Plan and Trust
to such amounts.

7.07. HARDSHIP WITHDRAWALS. Subject to the provisions of Article 8, a
Participant shall not be permitted to withdraw his Account (and earnings
thereon) prior to retirement or termination of employment, except if permitted
under Section 1.09, a Participant may apply to the Administrator to withdraw
some or all of his Account if such withdrawal is made on account of a hardship
as determined by the Employer.

ARTICLE 8.  DISTRIBUTION OF BENEFITS PAYABLE AFTER TERMINATION OF SERVICE.

8.01.  DISTRIBUTION OF BENEFITS TO PARTICIPANTS AND BENEFICIARIES.

           (a) Distributions under the Plan to a Participant or to the
       Beneficiary of the Participant shall be made in a lump sum in cash or, if
       elected by the Employer in Section 1.10 and specified in the
       Participant's deferral election, under a systematic withdrawal plan
       (installment(s))not exceeding 10 years upon retirement, death or other
       termination of employment.

           (b) Distributions under a systematic withdrawal plan must be made in
       substantially equal annual, or more frequent, installments, in cash, over
       a period certain which does not extend 10 years. The period certain
       specified in a Participant's first deferral election specifying
       distribution under a systematic withdrawal plan shall apply to all
       subsequent elections of distributions under a systematic withdrawal plan
       made by the Participant.

8.02. DETERMINATION OF METHOD OF DISTRIBUTION. The Participant will determine
the method of distribution of benefits to himself and the method of distribution
to his Beneficiary. Such determination will be made at the time the Participant
makes a deferral election. If the Participant does not determine the method of
distribution to him or his Beneficiary, the method shall be a lump sum.

8.03. NOTICE TO TRUSTEE. The Administrator will notify the Trustee in writing
whenever any Participant or Beneficiary is entitled to receive benefits under
the Plan. The Administrator's notice shall indicate the form, amount and
frequency of benefits that such Participant or Beneficiary shall receive.

8.04. TIME OF DISTRIBUTION. In no event will distribution to a Participant be
made later than the date specified by the Participant in his salary reduction
agreement.

ARTICLE 9.  AMENDMENT AND TERMINATION.

9.01 AMENDMENT BY EMPLOYER. The Employer reserves the authority to amend the
Plan by filing with the Trustee an amended Adoption Agreement, executed by the
Employer only, on which said Employer has indicated a change or changes in
provisions previously elected by it. Such changes are to be effective on the
effective date of such amended Adoption Agreement. Any such change
notwithstanding, no Participant's Account shall be reduced by such change below
the amount to which the Participant would have been entitled if he had
voluntarily left the employ of the Employer immediately prior to the date of the
change. The Employer may from time to time make any amendment to the Plan that
may be necessary to satisfy the Code or ERISA. The Employer's board of directors
or other individual specified in the resolution adopting this Plan shall act on
behalf of the Employer for purposes of this Section 9.01.

9.02 RETROACTIVE AMENDMENTS. An amendment made by the Employer in accordance
with Section 9.01 may be made effective on a date prior to the first day of the
Plan Year in which it is adopted if such amendment is necessary or appropriate
to enable the Plan and Trust to satisfy the applicable requirements of the Code
or ERISA or to conform the Plan to any change in federal law or to any
regulations or ruling thereunder. Any retroactive amendment by the Employer
shall be subject to the provisions of Section 9.01.

9.03. TERMINATION. The Employer has adopted the Plan with the intention and
expectation that contributions will be continued indefinitely. However, said
Employer has no obligation or liability whatsoever to maintain the Plan for any
length of time and may discontinue contributions under the Plan or terminate the
Plan at any time by written notice delivered to the Trustee without any
liability hereunder for any such discontinuance or termination.

9.04. DISTRIBUTION UPON TERMINATION OF THE PLAN. Upon termination of the Plan,
no further Deferral Contributions or Matching Contributions shall be made under
the Plan, but Accounts of Participants maintained under the Plan at the time of
termination shall continue to be governed by the terms of the Plan until paid
out in accordance with the terms of the Plan.

ARTICLE 10.  MISCELLANEOUS.

10.01. COMMUNICATION TO PARTICIPANTS. The Plan will be communicated to all
Participants by the Employer promptly after the Plan is adopted.

10 02. LIMITATION OF RIGHTS. Neither the establishment of the Plan and 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 the Employer, Administrator 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 affected hereby.

10.03. NONALIENABILITY OF BENEFITS. The benefits provided hereunder will not be
subject to alienation, assignment, garnishment, attachment, execution or levy of
any kind, either voluntarily or involuntarily, 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.

<PAGE>   15

10 04. FACILITY OF PAYMENT. In the event the Administrator determines, on the
basis of medical reports or other evidence satisfactory to the Administrator,
that the recipient of any benefit payments under the Plan is incapable of
handling his affairs by reason of minority, illness, infirmity or other
incapacity, the Administrator may direct the Trustee to disburse such payments
to a person or institution designated by a court which has jurisdiction over
such recipient or a person or institution otherwise having the legal authority
under State law for the care and control of such recipient. The receipt by such
person or institution of any such payments shall be complete acquittance
therefore, and any such payment to the extent thereof, shall discharge the
liability of the Trust for the payment of benefits hereunder to such recipient.

10.05. INFORMATION BETWEEN EMPLOYER AND TRUSTEE. The Employer agrees to furnish
the Trustee, and the Trustee agrees to furnish the Employer with such
information relating to the Plan and Trust as may be required by the other in
order to carry out their respective duties hereunder, including without
limitation information required under the Code or ERISA and any regulations
issued or forms adopted thereunder.

10.06. NOTICES. Any notice or other communication in connection with this Plan

       (a) Claims Procedure. If any person believes he is being denied any
       rights or benefits under the Plan, such person may file a claim in
       writing with the Administrator. If any such claim is wholly or partially
       denied, the Administrator will notify such person of its decision in
       writing. Such notification will contain (i) specific reasons for the
       denial, (ii) specific reference to pertinent Plan provisions, (iii) a
       description of any additional material or information necessary for such
       person to perfect such claim and an explanation of why such material or
       information is necessary, and (iv) information as to the steps to be
       taken if the person wishes to submit a request for review. Such
       notification will be given within 90 days after the claim is received by
       the Administrator (or within 180 days, if special circumstances require
       an extension of time for processing the claim, and if written notice of
       such extension and circumstances is given to such person within the
       initial 90-day period). If such notification is not given within such
       period, the claim will be considered denied as of the last day of such
       period and such person may request a review of his claim.

       (b) Review Procedure. Within 60 days after the date on which a person
       receives a written notice of a denied claim (or, if applicable, within 60
       days after the date on which such denial is considered to have occurred),
       such person (or his duly authorized representative) may (i) file a
       written request with the Administrator for a review of his denied claim
       and of pertinent documents and (ii) submit written issues and comments to

       calculated to be understood by such person and will contain specific
       reasons for the decision as well as specific references to pertinent Plan
       provisions. The decision on review will be made within 60 days after the
       request for review is received by the Administrator (or within 120 days,
       if special circumstances require an extension of time for processing the
       request, such as an

                                       12
<PAGE>   17

       election by the Administrator to hold a hearing, and if written notice of
       such extension and circumstances is given to such person within the
       initial 60-day period). If the decision on review is not made within such
       period, the claim will be considered denied.

11.04. COSTS OF ADMINISTRATION. Unless some or all costs and expenses are paid
by the Employer, all reasonable costs and expenses (including legal, accounting,
and employee communication fees) incurred by the Administrator and the Trustee
in administering the Plan and Trust will be paid first from the forfeitures (if
any) resulting under Section 7.05, then from the remaining Trust Fund. All such
costs and expenses paid from the Trust Fund will, unless allocable to the
Accounts of particular Participants, be charged against the Accounts of all
Participants on a prorata basis or in such other reasonable manner as may be
directed by the Employer.

required to furnish the Employee a written statement under Section 6041(d) and
6051(a)(3) of the code, excluding reimbursements or other expense allowances,
fringe benefits (cash and non-cash), moving expenses and welfare benefits, but
including (A) amounts deferred by an Employee under the terms of this Plan, the
Qualified Plan and any other nonqualified deferred compensation plans maintained

2.       Section 2.01(a) is hereby amended to add the following definitions:

         (28) "Disabled/Disability" shall have the same meaning as "Disabled"
and "Disability" as provided in the Employer's Long-Term Disability Plan.

         (29) "Qualified Plan" shall mean U.S. Enrichment Corporation's 401(k)
plan as in effect on the date of the adoption of this Plan and as amended from

3        Section 4.03 shall be amended to read in its entirety:

         4.03. Time of Making Employer Contributions. The Employer shall make a
transfer of assets to the Trustee on each pay period in accordance with Section
1.05(b). The Employer shall provide the Trustee with information on the amount

Trust.

4        Section 7.02 shall be amended to read in its entirety:

         7.02. Death or Disability. If a Participant dies or is Disabled before
the distribution of his Account has commenced, or before such distribution has
been completed, his Account shall become fully vested in accordance with the
vesting schedule elected in Section 1.07 and, in the event of Participant's
death, his designated Beneficiary or Beneficiaries, or, in the event of

<PAGE>   19

will be entitled to receive the balance or remaining balance of his Account,
plus any amounts thereafter credited to his Account, subject to the provisions
of Section 7.06. Distribution to the Disabled Participant or to the Beneficiary
or Beneficiaries will be made in accordance with Article 8.

shall be deemed to be the Beneficiary for purposes of the Plan). If a
Beneficiary dies after benefits to such Beneficiary have commenced, but before
they have been completed, and, in the opinion of the Administrator, no person
has been designated to receive such remaining benefits, then such benefits shall

the Participant, (ii) a loss of the Participant's property due to casualty, or
(iii) such other extraordinary and unforeseeable circumstances arising as a
result of events beyond the control of the Participant, all as determined in the

                      SYNDICATED REVOLVING PROMISSORY NOTE

$100,000,000                                                   November 15, 1999
                                                         Los Angeles, California

         1. FOR VALUE RECEIVED, USEC INC., a Delaware corporation ("Borrower")
hereby promises to pay to the order of each of the undersigned lenders (each a
"Lender" and collectively, the "Lenders") on the dates specified herein, in
lawful money of the United States, the amount of its Note Commitment, or such
lesser amount as shall equal the aggregate unpaid principal amount of each loan
(each a "Loan," and collectively, the "Loans")) made by such Lender under this
revolving promissory note (this "Note," and together with the Guaranty hereafter
referred to, the "Note Documents"), together with interest thereon at the times
and at the rates specified in this Note. Terms not defined herein shall have the
meanings assigned to them in that certain Revolving Loan Agreement dated as of
July 27, 1999 (together with amendments permitted hereunder, the "Loan
Agreement"), by and among Borrower, the lending institutions identified therein,
Bank of America, N.A., as administrative agent, First Union National Bank, as
syndication agent and Wachovia Bank, National Association, as documentation
agent.

         2. (a) Subject to the terms and conditions set forth herein, each
Lender hereby severally agrees to make revolving Loans to Borrower under this
Note in such amounts as Borrower may from time to time request in an aggregate
amount not to exceed at any time outstanding the amount set forth opposite such
Lender's name on Schedule 1 hereto (such Lender's "Note Commitment"). Borrower
may, at its discretion, request Loans on a nonratable basis from each Lender or
on a ratable basis from the Lenders; provided, however, that, after giving
effect to any borrowing, the aggregate principal amount of all outstanding Loans
made by any Lender shall not at any time exceed its Note Commitment and the
aggregate principal amount of all outstanding Loans made by all Lenders shall
not at any time exceed the combined Note Commitments. This is a revolving
credit, and within the limits of each Lender's Note Commitment and subject to
the other terms and conditions hereof, Borrower may reborrow amounts repaid or
prepaid until the Termination Date (as defined below).

         Each borrowing of Loans may be comprised of Base Rate Loans or
Eurodollar Rate Loans as selected by Borrower. Each borrowing of Eurodollar Rate
Loan shall be in the minimum amount of $5,000,000 with any additional amounts in
integral multiples of $1,000,000. Each borrowing of Base Rate Loan shall be in
the minimum amount of $1,000,000 with any additional amounts in integral
multiples of $1,000,000. Not more than five Eurodollar Periods may be
outstanding at any time. Each borrowing of Loans shall be made pursuant to a
Request for Loan delivered to Administrative Agent substantially in the form of
Exhibit A hereto which shall specify the requested (i) date of such Loan, (ii)
type of Loan, (iii) amount of each Lender's Loan, and (iv) in the case of a
Eurodollar Rate Loan, the Eurodollar Period for such Loan.

         Unless Administrative Agent has notified, in its sole and absolute
discretion, Borrower to the contrary, a Loan may be requested by telephone by a
Responsible Official of Borrower, in which case Borrower shall confirm such
request to Administrative Agent by promptly delivering

                                     - 1 -
<PAGE>   2

a Request for Loan in person or by telecopier conforming to the preceding
sentence to Administrative Agent. Neither Administrative Agent nor any Lender
shall incur any liability whatsoever hereunder in acting upon any telephonic
request for a Loan purportedly made by a Responsible Official of Borrower, and
Borrower hereby agrees to indemnify Administrative Agent and each Lender from
any loss, reasonable cost, out-of-pocket expense or liability as a result of so
acting.

         Borrower may request a borrowing of Base Rate Loans by delivering a
Request for Loan to Administrative Agent not later than 10:00 a.m. California
time on the date of any requested Base Rate Loan, and Borrower may request a
borrowing of Eurodollar Rate Loan by delivering a Request for Loan to
Administrative Agent not later than 11:00 a.m. California time at least three
Eurodollar Banking Days prior to any requested Eurodollar Rate Loan.
Administrative Agent shall promptly notify each Lender of each Request for Loan,
and each Lender shall make its Loan in immediately available funds to
Administrative Agent at its office indicated on Schedule 2 hereto not later than
10:00 a.m. California time on the date specified for any Loan (which must be a
Banking Day). Upon satisfaction or waiver by all Lenders of the applicable
conditions set forth in Paragraph 9, such Loans shall be made available to
Borrower on that date by such means as it may request in immediately available
funds. Administrative Agent may assume that all conditions set forth in
Paragraph 9 will be satisfied on any borrowing date unless otherwise notified by
any Lender or Borrower.

         (b) If, upon the expiration of any Eurodollar Period applicable to any
Eurodollar Rate Loan, Borrower has failed to select a new Eurodollar Period to
be applicable thereto, or if any Default or Event of Default shall then exist,
Borrower shall be deemed to have elected to convert such Eurodollar Rate Loan
into a Base Rate Loan effective as of the expiration date of such current
Eurodollar Period. No Lender shall be obligated to make or continue any
Eurodollar Rate Loan when any Default or Event of Default has occurred and is
continuing.

         3. (a) Upon notice to Administrative Agent, Borrower may at any time
prepay any Loan, in full or in part, in the manner and in the minimum amounts
and multiples thereof set forth in Section 3.1(f) of the Loan Agreement.
Prepayments may be made nonratably. Any prepayment of a Loan bearing interest at
the Eurodollar Rate shall be accompanied by the amount of accrued interest on
the amount prepaid, together with any amounts of the type specified in Section
3.8(e) of the Loan Agreement. Borrower may at any time permanently reduce or
terminate the Note Commitment upon five (5) Banking Days' notice to
Administrative Agent and, in the case of a reduction to an amount not less than
the outstanding principal amount of Loans. Reductions in Note Commitments may be
made nonratably.

         (b) The principal amount of all Loans shall be due and payable not
later than the earlier of (i) May 15, 2000 and (ii) the date the Note Commitment
is terminated by Borrower pursuant to Paragraph 3(a) above or by Lenders
pursuant to Paragraph 11 below (the "Termination Date").

         4. (a) Interest accrued on each Base Rate Loan shall be due and payable
on each Quarterly Payment Date and the Termination Date. Except as otherwise
provided in Paragraph 4(c) below, the unpaid principal amount of any Base Rate
Loan shall bear interest at a fluctuating rate per annum equal to the Base Rate.
Each change in the interest rate under this

                                     - 2 -
<PAGE>   3

subparagraph due to a change in the Base Rate shall take effect simultaneously
with the corresponding change in the Base Rate.

         (b) Interest accrued on each Eurodollar Rate Loan which is for a term
of three months or less shall be due and payable on the earlier of the last day
of the related Eurodollar Period and the Termination Date. Interest accrued on
each other Eurodollar Rate Loan shall be due and payable on the date which is
three months after the date such Eurodollar Rate Loan was made and on the last
day of the related Eurodollar Period. Except as otherwise provided in Paragraph
4(c) below, the unpaid principal amount of any Eurodollar Rate Loan shall bear
interest at a rate per annum equal to the Eurodollar Rate for that Eurodollar
Rate Loan plus the Applicable Eurodollar Margin.

         (c) If any installment of principal or interest or any fee or cost or
other amount payable under this Note to Administrative Agent or any Lender is
not paid when due, it shall thereafter bear interest at a fluctuating interest
rate per annum at all times equal to the sum of the Base Rate plus 2%, to the
fullest extent permitted by applicable Laws. Accrued and unpaid interest on past
due amounts (including, without limitation, interest on past due interest) shall
be compounded monthly, on the last day of each calendar month, to the fullest
extent permitted by applicable Laws.

         (d) Sections 3.10 through and including 3.17 of the Loan Agreement
shall apply hereunder.

         5. (a) From the date hereof, Borrower shall pay to Administrative Agent
for the account of each Lender a facility fee equal to the Applicable Facility
Fee Rate during the continuance of any Applicable Pricing Level per annum times
such Lender's Note Commitment in effect on each day during a fiscal quarter. The
facility fee shall be payable quarterly in arrears on each Quarterly Payment
Date and on the Termination Date.

         (b) Borrower shall pay to Administrative Agent for the account of each
Lender a utilization fee equal to .125% (12.5 basis points) per annum times the
aggregate unpaid principal amount of such Lender's Loans for each day (or
portion thereof) that its Loans are in excess of 33-1/3% of such Lender's Note
Commitment. The utilization fee shall be payable quarterly in arrears on each
Quarterly Payment Date and on the Termination Date.

         6. Fees and interest hereunder shall be calculated in the same manner
as provided by Section 3.10 of the Loan Agreement (Computation of Interest and
Fees) and payments shall be made by Borrower to Administrative Agent and by
Administrative Agent to each Lender in the same manner as provided by Section
3.12 of the Loan Agreement (Manner and Treatment of Payments). Subject to the
last sentence of Paragraph 19(a), Lenders shall comply with Section 11.10 of the
Loan Agreement (Sharing of Setoffs). Administrative Agent shall be entitled to
the benefits of Section 2.9 of the Loan Agreement (Administrative Agent's right
to Assume Funds Available for Advances) and Section 3.15 of the Loan Agreement
(Administrative Agent's right to Assume Payments Will be Made).

         7. Upon demand of any Lender, Borrower shall pay costs of the type set
forth in Sections 3.7 and 3.8 of the Loan Agreement (subject to the terms and
conditions set forth in

                                     - 3 -
<PAGE>   4

Section 3), and availability of Eurodollar Rate Loans shall be subject to
matters of the type set forth in Sections 3.8(c) and (d) of the Loan Agreement.

         1. DEFINITIONS. This Guaranty is the Guaranty referred to in the Note.
Terms defined in the Note and not otherwise defined in this Guaranty shall have

                            Subsidiary Note Guaranty
<PAGE>   11

                  "Contribution" means any payment made by a Guarantor hereunder
         or any recourse taken by any Guarantied Party against any collateral
         owned by the Guarantors which secures any Guarantied Obligation.

                  "Guarantied Obligations" means all Note Obligations of
         Borrower at any time and from time to time owed to any Guarantied Party
         under one or more of the Note Documents (but not including Note
         Obligations owed to any Guarantied Party under this Guaranty), whether
         due or to become due, matured or unmatured, liquidated or unliquidated,
         or contingent or noncontingent, including obligations of performance as
         well as obligations of payment, and including interest that accrues
         after the commencement of any bankruptcy or insolvency proceeding by or
         against Borrower, any Guarantor or any other Person.

                  "Guarantied Parties" means Administrative Agent and Lenders
         (each a "Guarantied Party").

                  "Guarantors" means the parties hereto as indicated on the
         signature pages hereof, or such additional Person as may become parties
         hereto pursuant to Section 17 hereof, and each of them, and any one or
         more of them, jointly and severally.

                  "Guaranty" means this Guaranty, and any extensions,
         modifications, renewals, restatements, reaffirmations, supplements or
         amendments hereof, including, without limitation, any documents or
         agreements by which additional Guarantors become party hereto.

         2. GUARANTY OF GUARANTIED OBLIGATIONS. Guarantors hereby, jointly and
severally, irrevocably, unconditionally guaranty and promise to pay and perform
on demand the Guarantied Obligations and each and every one of them, including
all amendments, modifications, supplements, renewals or extensions of any of
them, whether such amendments, modifications, supplements, renewals or
extensions are evidenced by new or additional instruments, documents or
agreements or change the rate of interest on any Guarantied Obligation or the
security therefor, or otherwise.

         3. NATURE OF GUARANTY. This Guaranty is irrevocable and continuing in
nature and relates to any Guarantied Obligations now existing or hereafter
arising. This Guaranty is a guaranty of prompt and punctual payment and
performance and is not merely a guaranty of collection.

         4. RELATIONSHIP TO OTHER AGREEMENTS. Nothing herein shall in any way
modify or limit the effect of terms or conditions set forth in any other
document, instrument or agreement executed by any Guarantor or in connection
with the Guarantied Obligations, but each and every term and condition hereof
shall be in addition thereto. All provisions contained in the Note or any other
Note Document that apply to Note Documents generally are fully applicable to
this Guaranty and are incorporated herein by this reference.

         5. SUBORDINATION OF INDEBTEDNESS OF BORROWER TO GUARANTORS TO THE
GUARANTIED OBLIGATIONS. Each Guarantor agrees that:

                                     - 2 -
                            Subsidiary Note Guaranty
<PAGE>   12

         (a) Any indebtedness of Borrower now or hereafter owed to any Guarantor
hereby is subordinated to the Guarantied Obligations.

         (b) If any Guarantied Party so requests, upon the occurrence and during
the continuance of any Event of Default, any such indebtedness of Borrower now
or hereafter owed to any Guarantor shall be collected, enforced and received by
such Guarantor as trustee for the Guarantied Parties and shall be paid over to
Administrative Agent for the benefit of the Guarantied Parties in kind on
account of the Guarantied Obligations, but without reducing or affecting in any
manner the obligations of such Guarantor under the other provisions of this
Guaranty.

         (c) Should such Guarantor fail to collect or enforce any such
indebtedness of Borrower now or hereafter owed to such Guarantor and pay the
proceeds thereof to Administrative Agent for the benefit of the Guarantied
Parties in accordance with Section 5(b) hereof, each Guarantied Party as such
Guarantor's attorney-in-fact may do such acts and sign such documents in such
Guarantor's name as such Guarantied Party considers necessary or desirable to
effect such collection, enforcement and/or payment.

         6. STATUTES OF LIMITATIONS AND OTHER LAWS. Until the Guarantied
Obligations shall have been paid and performed in full, all the rights,
privileges, powers and remedies granted to the Guarantied Parties hereunder
shall continue to exist and may be exercised by the Guarantied Parties at any
time and from time to time irrespective of the fact that any of the Guarantied
Obligations may have become barred by any statute of limitations. Each Guarantor
expressly waives the benefit of any and all statutes of limitation, and any and
all Laws providing for exemption of property from execution or for evaluation
and appraisal upon foreclosure, to the maximum extent permitted by applicable
Laws.

         7. WAIVERS AND CONSENTS. Each Guarantor acknowledges that the
obligations undertaken herein involve the guaranty of obligations of Persons
other than such Guarantor and, in full recognition of that fact, consents and
agrees that any Guarantied Party may, at any time and from time to time, without
notice or demand, and without affecting the enforceability or continuing
effectiveness hereof: (a) supplement, modify, amend, extend, renew, accelerate
or otherwise change the time for payment or the terms of the Guarantied
Obligations or any part thereof, including any increase or decrease of the
rate(s) of interest thereon; (b) supplement, modify, amend or waive, or enter
into or give any agreement, approval or consent with respect to, the Guarantied
Obligations or any part thereof, or any of the Note Documents to which such
Guarantor is not a party or any additional security or guaranties, or any
condition, covenant, default, remedy, right, representation or term thereof or
thereunder; (c) accept new or additional instruments, documents or agreements in
exchange for or relative to any of the Note Documents or the Guarantied
Obligations or any part thereof; (d) accept partial payments on the Guarantied
Obligations; (e) receive and hold additional security or guaranties for the
Guarantied Obligations or any part thereof; (f) release, reconvey, terminate,
waive, abandon, fail to perfect, subordinate, exchange, substitute, transfer
and/or enforce any security or guaranties, and apply any security and direct the
order or manner of sale thereof as any Guarantied Party in its sole and absolute
discretion may determine; (g) release any Person from any personal liability
with respect to the Guarantied Obligations or any part thereof; (h) settle,
release on terms satisfactory to the Guarantied Parties or by operation of
applicable Laws or otherwise liquidate or enforce any

                                     - 3 -
                            Subsidiary Note Guaranty
<PAGE>   13

Guarantied Obligations and any security or guaranty therefor in any manner,
consent to the transfer of any security and bid and purchase at any sale; and/or
(i) consent to the merger, change or any other restructuring or termination of
the corporate existence of Borrower, any Guarantor or any other Person, and
correspondingly restructure the Guarantied Obligations, and any such merger,
change, restructuring or termination shall not affect the liability of any
Guarantor or the continuing effectiveness hereof, or the enforceability hereof
with respect to all or any part of the Guarantied Obligations.

         Upon the occurrence and during the continuance of any Event of Default,
each Guarantied Party may enforce this Guaranty independently as to each
Guarantor and independently of any other remedy or security the Guarantied
Parties at any time may have or hold in connection with the Guarantied
Obligations. Each Guarantor expressly waives any right to require any Guarantied
Party to marshal assets in favor of Borrower, and agrees that the Guarantied
Parties may proceed against Borrower, or upon or against any security or remedy,
before proceeding to enforce this Guaranty, in such order as they shall
determine in their sole and absolute discretion. Any Guarantied Party may file a
separate action or actions against Borrower and/or any Guarantor without respect
to whether action is brought or prosecuted with respect to any security or
against any other Person, or whether any other Person is joined in any such
action or actions. Guarantors agree that the Guarantied Parties and Borrower and
any Affiliates of Borrower may deal with each other in connection with the
Guarantied Obligations or otherwise, or alter any contracts or agreements now or
hereafter existing between any of them, in any manner whatsoever, all without in
any way altering or affecting the security of this Guaranty. Each Guarantied
Parties' rights hereunder shall be reinstated and revived, and the
enforceability of this Guaranty shall continue, with respect to any amount at
any time paid on account of the Guarantied Obligations which thereafter shall be
required to be restored or returned by the Guarantied Parties upon the
bankruptcy, insolvency or reorganization of Borrower or any other Person, or
otherwise, all as though such amount had not been paid. The rights of each
Guarantied Party created or granted herein and the enforceability of this
Guaranty with respect to Guarantors at all times shall remain effective to
guaranty the full amount of all the Guarantied Obligations even though the
Guarantied Obligations, or any part thereof, or any security or guaranty
therefor, may be or hereafter may become invalid or otherwise unenforceable as
against Borrower or any other guarantor or surety and whether or not Borrower
shall have any personal liability with respect thereto. Each Guarantor expressly
waives any and all defenses now or hereafter arising or asserted by reason of
(a) any disability or other defense of Borrower with respect to the Guarantied
Obligations, (b) the unenforceability or invalidity of any security or guaranty
for the Guarantied Obligations or the lack of perfection or continuing
perfection or failure of priority of any security for the Guarantied
Obligations, (c) the cessation for any cause whatsoever of the liability of
Borrower (other than by reason of the full payment and performance of all
Guarantied Obligations), (d) any failure of any Guarantied Party to marshal
assets in favor of Borrower or any other Person, (e) except as otherwise
provided in this Guaranty, any failure of any Guarantied Party to give notice of
sale or other disposition of collateral securing any Guarantied Obligations to
such Guarantor or any other Person or any defect in any notice that may be given
in connection with any sale or disposition of any collateral, (f) except as
otherwise provided in this Guaranty, any failure of any Guarantied Party to
comply with applicable Laws in connection with the sale or other disposition of
any collateral or other security for any Guarantied Obligation, including
without limitation, any failure of any

                                     - 4 -
                            Subsidiary Note Guaranty
<PAGE>   14

Guarantied Party to conduct a commercially reasonable sale or other disposition
of any collateral or other security for any Guarantied Obligation, (g) any act
or omission of any Guarantied Party or others that directly or indirectly
results in or aids the discharge or release of Borrower or the Guarantied
Obligations or any security or guaranty therefor by operation of law or
otherwise, (h) any Law which provides that the obligation of a surety or
guarantor must neither be larger in amount nor in other respects more burdensome
than that of the principal or which reduces a surety's or guarantor's obligation
in proportion to the principal obligation, (i) any failure of any Guarantied
Party to file or enforce a claim in any bankruptcy or other proceeding with
respect to any Person, (j) the election by any Guarantied Party, in any
bankruptcy proceeding of any Person, of the application or non-application of
Section 1111(b)(2) of the United States Bankruptcy Code, (k) any extension of
credit or the grant of any Lien under Section 364 of the United States
Bankruptcy Code, (l) any use of cash collateral under Section 363 of the United
States Bankruptcy Code, (m) any agreement or stipulation with respect to the
provision of adequate protection in any bankruptcy proceeding of any Person, (n)
the avoidance of any Lien in favor of any Guarantied Party for any reason, (o)
any bankruptcy, insolvency, reorganization, arrangement, readjustment of debt,
liquidation or dissolution proceeding commenced by or against any Person,
including any discharge of, or bar or stay against collecting, all or any of the
Guarantied Obligations (or any interest thereon) in or as a result of any such
proceeding, (p) to the extent permitted, the benefits of any form of one-action
rule, or (q) any action taken by any Guarantied Party that is authorized by this
Section or any other provision of any Note Document. Each Guarantor expressly
waives all setoffs and counterclaims and all presentments, demands for payment
or performance, notices of nonpayment or nonperformance, protests, notices of
protest, notices of dishonor and all other notices or demands of any kind or
nature whatsoever with respect to the Guarantied Obligations, and all notices of
acceptance of this Guaranty or of the existence, creation or incurrence of new
or additional Guarantied Obligations.

         8. CONDITION OF BORROWER AND ITS SUBSIDIARIES. Each Guarantor
represents and warrants to each Guarantied Party that each Guarantor has
established adequate means of obtaining from Borrower and its Subsidiaries, on a
continuing basis, financial and other information pertaining to the businesses,
operations and condition (financial and otherwise) of Borrower and its
Subsidiaries and their Properties, and each Guarantor now is and hereafter will
be completely familiar with the businesses, operations and condition (financial
and otherwise) of Borrower and its Subsidiaries and their Properties. Each
Guarantor hereby expressly waives and relinquishes any duty on the part of any
Guarantied Party (should any such duty exist) to disclose to any Guarantor any
matter, fact or thing related to the businesses, operations or condition
(financial or otherwise) of Borrower or its Subsidiaries or their Properties,
whether now known or hereafter known by any Guarantied Party during the life of
this Guaranty. With respect to any of the Guarantied Obligations, each
Guarantied Party shall be entitled to conclusively rely upon any document or
certificate that is executed by a Responsible Official of Borrower as having
been authorized by all necessary corporate, partnership and/or other action on
the part of Borrower; provided that such Responsible Official has been
designated as a Responsible Official for the purposes of the Loan Agreement or
the Note in a written notice signed by a Senior Officer and delivered to
Administrative Agent, which notice has not been cancelled or suspended, and all
Guarantied Obligations made or created thereby shall be secured hereby.

                            Subsidiary Note Guaranty
<PAGE>   15

         9. LIENS ON REAL PROPERTY. In the event that all or any part of the
Guarantied Obligations at any time are secured by any one or more deeds of trust
or mortgages or other instruments creating or granting Liens on any interests in
real Property, each Guarantor authorizes each Guarantied Party, upon the
occurrence of and during the continuance of any Event of Default, at its sole
option, without notice or demand and without affecting any Guarantied
Obligations of any Guarantor, the enforceability of this Guaranty, or the
validity or enforceability of any Liens of any Guarantied Party on any
collateral securing any Guarantied Obligations, to foreclose any or all of such
deeds of trust or mortgages or other instruments by judicial or nonjudicial
sale, subject to the terms thereof. Each Guarantor expressly waives any defenses
to the enforcement of this Guaranty or any rights of any Guarantied Party
created or granted hereby or to the recovery by any Guarantied Party against
Borrower, any Guarantor or any other Person liable therefor of any deficiency
after a judicial or nonjudicial foreclosure or sale, even though such a
foreclosure or sale may impair the subrogation rights of any Guarantor or may
preclude any Guarantor from obtaining reimbursement or contribution from
Borrower. Each Guarantor expressly waives any defenses or benefits that may be
provided by California Code of Civil Procedure Sections 580a, 580b, 580d or 726,
or comparable provisions of the Laws of any other jurisdiction, and all other
suretyship defenses it otherwise might or would have under California Law or
other applicable Law.

         10. WAIVER OF RIGHTS OF SUBROGATION. Notwithstanding anything to the
contrary elsewhere contained herein or in any other Note Document to which any
Guarantor is a party, Guarantors hereby expressly waive with respect to Borrower
and their successors and assigns (including any surety) and any other Person
which is directly or indirectly a creditor of Borrower or any surety for
Borrower, any and all rights at Law or in equity to subrogation, to
reimbursement, to exoneration, to contribution (except as specifically provided
in Section 11 below), to setoff or to any other rights that could accrue to a
surety against a principal, to a guarantor against a maker or obligor, to an
accommodation party against the party accommodated, or to a holder or transferee
against a maker, and which Guarantors may have or hereafter acquire against
Borrower or any other such Person in connection with or as a result of
Guarantors' execution, delivery and/or performance of this Guaranty or any other
Note Document to which any Guarantor is a party until payment in full of all
Guarantied Obligations. Guarantors agree that they shall not have or assert any
such rights against Borrower or its successors and assigns or any other Person
(including any surety) which is directly or indirectly a creditor of Borrower or
any surety for Borrower, either directly or as an attempted setoff to any action
commenced against Guarantors by Borrower (as borrower or in any other capacity),
any Guarantied Party or any other such Person until such payment in full.
Guarantors hereby acknowledge and agree that this waiver is intended to benefit
Borrower and each Guarantied Party and shall not limit or otherwise affect
Guarantors' liability hereunder, under any other Note Document to which any
Guarantor is a party, or the enforceability hereof or thereof.

         11. RIGHT OF CONTRIBUTION, INDEMNITY AND ALLOCATION. In order to
provide for just and equitable contribution among the Guarantors in the event
any Contribution is made by a Guarantor (a "Funding Guarantor") under this
Guaranty, that Funding Guarantor shall be entitled to a Contribution from
certain other Guarantors for all payments, damages and expenses incurred by that
Funding Guarantor in discharging any of the Obligations, in the manner and to
the extent set forth in this Guaranty. The amount of any Contribution under this
Guaranty shall be equal to

                                     - 6 -
                            Subsidiary Note Guaranty
<PAGE>   16

the payment made pursuant to the Note, or the fair saleable value of such
Funding Guarantor's portion of any collateral securing any Guarantied Obligation
against which recourse is exercised, and shall be determined as of the date on
which such payment is made or recourse is exercised, as the case may be.

         (a) BENEFIT AMOUNT DEFINED. For purposes of this Guaranty, the "Benefit
Amount" of any Guarantor as of any date of determination shall be the net value
of the benefits to such Guarantor from extensions of credit made by any
Guarantied Party to Borrower for the benefit of such Guarantor under the Note.
Such benefits shall include, without limitation, benefits of funds constituting
proceeds of Loans which are deposited into the account of Borrower by any
Guarantied Party which are in turn advanced or contributed by Borrower to such
Guarantor, and the benefit of any assets acquired by Borrower and transferred to
such Guarantor if the acquisition of such assets was financed by Borrower, in
whole or in part, with the proceeds of Loans reserved by Borrower (collectively,
the "Benefits").

         (b) CONTRIBUTION OBLIGATION. Each Guarantor shall be liable to a
Funding Guarantor in an amount equal to the greater of (A) the product of (i) a
fraction, the numerator of which is (x) the Benefit Amount of such Guarantor,
and the denominator of which is (y) the total amount of Obligations and (ii) the
amount of Obligations paid by such Funding Guarantor and (B) 95% of the excess
of the fair saleable value of the property of such Guarantor over the total
liabilities of such Guarantor (including the maximum amount reasonably expected
to become due in respect of contingent liabilities), as the case may be,
determined as of the date on which the payment made by a Funding Guarantor is
deemed made for purposes of this Guaranty or any recourse is exercised against
any Funding Guarantor's portion of any collateral securing any Guarantied
Obligation, as the case may be (giving effect to all payments by other Funding
Guarantors and to the exercise of recourse against any other Funding Guarantor's
portion of any collateral securing any Guarantied Obligation as of such date in
a manner to maximize the amount of such Contributions).

         (c) ALLOCATION. In the event that at any time there exists more than
one Funding Guarantor with respect to any Contribution (in any such case, the
"Applicable Contribution"), then payment from other Guarantors pursuant to this
Guaranty shall be allocated among such Funding Guarantors in proportion to the
total amount of the Contribution made for or on account of the Guarantors by
each such Funding Guarantor pursuant to the Applicable Contribution. In the
event that at any time any Guarantor pays an amount under this Guaranty in
excess of the amount calculated pursuant to clause (A) of Section 11(b), that
Guarantor shall be deemed and shall be entitled to Contribution from the other
Guarantors in accordance with the provisions of this Guaranty.

         (d) PRESERVATION OF RIGHTS. This Guaranty shall not limit any right
which any Guarantor may have against any other Person which is not a party
hereto.

         (e) EQUITABLE ALLOCATION. If as a result of any reorganization,
recapitalization, or other corporate change in a Guarantor, or as a result of
any amendment, waiver or modification of the terms and conditions governing the
Note or the Guarantied Obligations, or for any other reason, the Contributions
under this Guaranty become inequitable, the parties hereto shall promptly modify
and amend this Guaranty to provide for an equitable allocation of the

Contributions. Any of the foregoing modifications and amendments to this
Guaranty shall be in writing and signed by all parties hereto.

         (f) ASSET OF PARTY TO WHICH CONTRIBUTION IS OWING. The parties hereto
acknowledge that the right to Contribution hereunder shall constitute an asset
in favor of the party to which such Contribution is owing.

         (g) INDEMNITY. Each Guarantor agrees to indemnify and hold harmless any
Funding Guarantor for the contribution Obligation of such Guarantor (as
determined in accordance with Section 11(b) of this Guaranty) paid by such
Funding Guarantor.

         12. UNDERSTANDINGS WITH RESPECT TO WAIVERS AND CONSENTS. Each Guarantor
warrants and agrees that each of the waivers and consents set forth herein are
made with full knowledge of their significance and consequences, with the
understanding that events giving rise to any defense or right waived may
diminish, destroy or otherwise adversely affect rights which Guarantor otherwise
may have against Borrower, any Guarantied Party or others, or against any
collateral securing any Guarantied Obligations and that, under the
circumstances, the waivers and consents herein given are reasonable and not
contrary to public policy or Law. Each Guarantor acknowledges that it has either
consulted with legal counsel regarding the effect of this Guaranty and the
waivers and consents set forth herein, or has made an informed decision not to
do so. If this Guaranty or any of the waivers or consents herein are determined
to be unenforceable under or in violation of applicable Law, this Guaranty and
such waivers and consents shall be effective to the maximum extent permitted by
Law.

         13. REPRESENTATIONS AND WARRANTIES. Each Guarantor hereby makes each
and every representation and warranty applicable to such Guarantor set forth in
Article 4 of the Loan Agreement as if set forth in full herein referring mutatis
mutandis to the Note Documents.

         14. COSTS AND EXPENSES. Each Guarantor agrees to pay to each Guarantied
Party all reasonable costs and out-of-pocket expenses (including, without
limitation, reasonable attorneys' fees and disbursements) incurred by any
Guarantied Party in the enforcement or attempted enforcement of this Guaranty,
whether or not an action is filed in connection therewith, and in connection
with any waiver or amendment of any term or provision hereof. All advances,
charges, costs and expenses, including reasonable attorneys' fees and
disbursements (including the reasonably allocated cost of legal counsel employed
by any Guarantied Party), incurred or paid by any Guarantied Party in exercising
any right, privilege, power or remedy conferred by this Guaranty, or in the
enforcement or attempted enforcement thereof, shall be subject hereto and shall
become a part of the Guarantied Obligations and shall be paid to each Guarantied
Party by each Guarantor, immediately upon demand, together with interest thereon
at the rate(s) provided for under the Note.

         15. CONSTRUCTION OF THIS GUARANTY. This Guaranty is intended to give
rise to absolute and unconditional obligations on the part of each Guarantor.

         16. LIABILITY. Notwithstanding anything to the contrary elsewhere
contained herein or in any Note Document to which any Guarantor is a party, the
aggregate liability of all Guarantors hereunder for payment and performance of
the Guarantied Obligations shall not

                                     - 8 -
                            Subsidiary Note Guaranty
<PAGE>   18

exceed an amount which, in the aggregate, is $1.00 less than that amount which
if so paid or performed would constitute or result in a "fraudulent transfer",
"fraudulent conveyance", or terms of similar import, under applicable state or
federal Law, including without limitation, Section 548 of the United States
Bankruptcy Code. The liability of each Guarantor hereunder is independent of any
other guaranties at any time in effect with respect to all or any part of the
Guarantied Obligations, and each Guarantor's liability hereunder may be enforced
regardless of the existence of any such guaranties. Any termination by or
release of any guarantor in whole or in part (whether it be another Guarantor
under this instrument or not) shall not affect the continuing liability of any
Guarantor hereunder, and no notice of any such termination or release shall be
required. The execution hereof by each Guarantor is not founded upon an
expectation or understanding that there will be any other guarantor of the
Guarantied Obligations.

         17. ADDITIONAL GUARANTORS. Any other Person may become an additional
Guarantor under and become bound by the terms and conditions of this Guaranty by
executing and delivering to Administrative Agent an Instrument of Joinder
substantially in the form attached hereto as Exhibit A, accompanied by such
documentation as Administrative Agent may require to establish the due
organization, valid existence and good standing of such Person, its
qualification to engage in business in each material jurisdiction in which it is
required to be so qualified, its authority to execute, deliver and perform this
Guaranty, and the identity, authority and capacity of each Senior Officer
thereof authorized to act on its behalf. Upon delivery of such Instrument of
Joinder to and acceptance thereof by Administrative Agent, notice of which
acceptance is hereby waived by Guarantors, each such additional Guarantor shall
be as fully a party hereto as if such Guarantor were an original signatory
hereof. Each Guarantor expressly agrees that its obligations hereunder and under
any other Note Document shall not be affected or diminished by the addition or
release of additional Guarantors hereunder, nor by any election of any
Guarantied Party not to cause any Subsidiary of Borrower to become and
additional Guarantor hereunder. This Guaranty shall be fully effective as to any
Guarantor who is or becomes a party hereto regardless of whether any other
Person becomes or fails to become or ceases to be a Guarantor hereunder.

         18. RELEASE OF GUARANTORS. This Guaranty and all obligations of
Guarantors hereunder shall be released when all Note Obligations of each Party
to any Note Document have been paid in full in cash or otherwise performed in
full and when no portion of the Note Commitment remains outstanding and as
otherwise set forth in the Note.

         19. MISCELLANEOUS. Subject to Section 15 hereof, each of the Guarantors
consents and agrees to the obligations and other terms imposed upon such
Guarantor, and each of the Note Documents to which such Guarantor is party, by
the terms of the Note. Without limiting the foregoing:

         (a) Neither this Guaranty nor any other Note Document to which any
Guarantor is party shall be amended, modified, supplemented, extended,
terminated or waived (explicitly or by implication) except in such manner as may
be permitted by the terms of the Note.

         (b) Any Note Document to which any Guarantor is party may be executed
in one or more counterparts, each of which shall be deemed an original and all
of which, taken together, shall constitute one and the same agreement.

<PAGE>   19

         20. NOTICES. Any notice or other communication made under this Guaranty
shall be in writing and shall be deemed to be properly given if done in
accordance with Section 11.6 of the Loan Agreement. The notice address for each
Guarantor is set forth on the signature page hereof (or the Instrument of
Joinder executed by such party, if applicable).

         21. COMPLETE AGREEMENT. This Guaranty, together with the other Note
Documents executed by each Guarantor, comprises the complete and integrated
agreement of the parties on the subject matter hereof and supersedes all prior
agreements, written or oral, on the subject matter hereof.

         22. WAIVER OF JURY TRIAL. EACH GUARANTOR AND each Guarantied Party
EXPRESSLY WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM, DEMAND,
ACTION OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF OR RELATED TO THIS
GUARANTY, THE NOTE, THE OTHER NOTE DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED
HEREBY OR THEREBY IN ANY ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE
BROUGHT BY ANY OF THE PARTIES AGAINST ANY OTHER PARTY OR PARTIES, WHETHER NOW
EXISTING OR HEREAFTER ARISING AND WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT
CLAIMS, OR OTHERWISE. EACH GUARANTOR AND each Guarantied Party AGREE THAT ANY
SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL
WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT
THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION
AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN
PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS GUARANTY, THE NOTE AND
THE OTHER NOTE DOCUMENTS OR ANY PROVISION HEREOF OR THEREOF. THIS WAIVER SHALL
APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO
THIS GUARANTY, THE NOTE AND THE OTHER NOTE DOCUMENTS. ANY PARTY HERETO MAY FILE
AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN
EVIDENCE OF THE CONSENT OF THE SIGNATORIES HERETO TO THE WAIVER OF THEIR RIGHT
TO TRIAL BY JURY.

         23. GOVERNING LAW. THIS GUARANTY SHALL BE GOVERNED BY, AND SHALL BE
CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE INTERNAL LAWS OF NEW YORK.
