                     (7) The term "COMPANY CONTRIBUTIONS" shall mean the
               discretionary contributions made by the Employers under the Plan
               in accordance with the provisions of Section 4.1. Company
               Contributions shall be allocated and deposited to the Company
               Contributions Accounts of Participants pursuant to the provisions
               of Sections 4.6 and 6.1.

                     (8) The term "COMPANY CONTRIBUTION ACCOUNT" shall mean the
               Account of a Participant which reflects his interest in the Funds
               attributable to Company Contributions and forfeitures, if any,
               and which is established pursuant to the provisions of Sections
               4.1, 6.1, and 7.3.

                     (9) The term "COMPENSATION" shall mean the total wages
               which are paid to an Employee during a Plan Year by an Employer
               for his services as an Employee while he is a Participant, but
               excluding any portion of a Company Contribution which is subject
               to the cash option election described in Section 4.2 and which a
               Participant elects to receive in cash, any amounts received under
               the Company's dependent scholarship program, and all non-cash
               remuneration; provided, however, that for Plan Years beginning on
               or after January 1, 1994, the annual Compensation of a
               Participant taken into account under the Plan shall not exceed
               the OBRA `93 annual compensation limit of $150,000, as adjusted
               for increases in the cost of living in accordance with the
               provisions of Section 401(a)(17)(B) of the Code. The cost of
               living in effect for a calendar year applies to any period, not
               exceeding 12 months, over which Compensation is determined (a
               "determination period") beginning in such calendar year. If a
               determination period consists of fewer than 12 months, the OBRA
               `93 annual compensation limit will be multiplied by a fraction,
               the numerator of which is the number of months in the
               determination period and the denominator of which is 12.
               Compensation of a Participant's "family members" (as defined in

               modified by Section 401(a)(17) of the Code. If as a result of the
               application of such rules the adjusted Section 401(a)(17)
               limitation is exceeded, then the limitation shall be prorated in
               proportion to each such individual's compensation as determined
               under such paragraph prior to the application of such limitation.

                     (10)  The term "ELIGIBLE RETIREMENT PLAN" shall mean:

                           (a)    an individual retirement account described in

               provided that such alternate payee is a Participant's spouse or
               former spouse; and provided further that such distribution is not

               the following requirements:

                           (a)    It must be primarily for the benefit of

                                  event of default;

                           (e)    It may be secured by a pledge of OMG Stock

                                  Loan. No other assets of the OMG ESOP may be
                                  pledged as collateral for an Exempt Loan and
                                  no lender shall have recourse against any
                                  other assets of the OMG ESOP. No person
                                  entitled to payment under the Exempt Loan
                                  shall have any recourse against any assets of

                                  (3)   earnings on such collateral and the
                                        investment of such contributions.

                                  In the event of default, the value of OMG ESOP

                                  in interest under ERISA, the Exempt Loan must
                                  provide for the transfer of OMG ESOP assets

                                  Loan payment schedule.

                           (f)    It must provide for the release of OMG Stock
                                  from encumbrance either under the principal

               If the number of officers for any Plan Year exceeds the maximum
               number that may be counted, the officers shall be ranked in order
               of compensation (as defined in Appendix A of the Plan without
               regard to Sections 125, 402(e)(3), and 402(h)(1)(B) of the Code,
               and in the case of Tax Deferred Contributions made pursuant to a
               salary reduction agreement, without regard to Section 403(b) of
               the Code) for the Plan Year, and only the maximum number with the
               highest such compensation shall be counted as officers. If for
               any Plan Year no Employer has an officer with compensation
               greater than the compensation specified in subparagraph (c)
               above, the highest-paid officer among the Employers shall
               nevertheless be treated as a Highly-Compensated Employee. If
               during any Plan Year an Employee is a "family member" of a
               Highly-Compensated Employee described above in subparagraph (d)
               or of a Highly-Compensated Employee in the group consisting of
               the ten Highly-Compensated Employees paid the greatest
               compensation during the Plan Year, then such "family member"
               shall not be considered to be a separate Employee and the
               compensation paid to such "family member" and any applicable
               Employer contribution under the Plan paid to or on behalf of such
               "family member" shall be treated as if it were paid to (or on
               behalf of) the related Highly-Compensated Employee. As used
               herein, the term "family member" means with respect to any
               Employee, the Employee's spouse, grandparent (and spouse), great
               grandparent (and spouse), child (and spouse), grandchild (and
               spouse), great grandchild (and spouse) and any other lineal
               ascendants or descendants and their spouses and for purposes of
               applying the limitation of Section 401(a)(17) to paragraph (9) of
               this Section 1.1 shall mean the spouse of any Employee and any
               lineal descendant thereof who has not attained age 19 before the
               close of the Plan Year. In addition, a former Employee shall be
               considered a Highly-Compensated Employee if he was a
               Highly-Compensated Employee at the time his employment terminated
               or at any time after attaining age 55. Notwithstanding the
               foregoing provisions of this paragraph (18), the sole purpose of
               this paragraph is to define and apply the term Highly-Compensated
               Employee strictly (and only) to the extent

                                       7

               of the Code relating to "highly-compensated employees." This
               paragraph (18) shall be interpreted, applied and, if and to the
               extent necessary, deemed modified without formal amendments of
               language, so as to satisfy solely the minimum requirements of

                           402(e)(3), 402(h)(1)(B)) and which provides for
                           immediate participation and full and immediate
                           vesting; provided, however, that this sentence shall
                           be applicable only if Leased Workers do not
                           constitute more than 20% of the recipient's nonhighly
                           compensated workforce, as determined in accordance

               after December 31, 1983 shall be considered an employee of the

               extent necessary to satisfy the minimum requirements of Section
               414(n) of the Code relating to "leased employees". This paragraph
               (20) shall be interpreted, applied and, if and to the extent
               necessary, deemed modified without formal amendment of language,
               so as to satisfy solely the minimum requirements of Section

                                HOURS OF SERVICE
                                ----------------

               2.1 CREDITING OF HOURS OF SERVICE.  An Employee  shall be
credited  with an Hour of Service under the Plan for:
                     (a) each hour for which he is paid, or entitled to payment,
               for the performance of duties for an Employer or a Related
               Corporation; provided, however, that hours paid for at a premium
               rate shall be treated as straight-time hours; and provided
               further, that if a record of hours of employment is not
               available, the Employee shall be deemed to have worked 45 hours
               for each week of employment in which he performed an Hour of
               Service, regardless of whether the Employee has actually worked
               fewer hours;

                     (b) each hour for which he is paid, or entitled to payment,
               by an Employer or a Related Corporation on account of a period of
               time during which no duties are performed (irrespective of
               whether he remains an Employee) due to vacation, holiday,
               illness, incapacity (including disability), lay-off, jury duty,
               military duty, or leave of absence, up to a maximum of eight
               hours per day and 40 hours per week; provided, however, that no
               more than 501 hours of service shall be credited to an Employee
               on account of any single continuous period during which he
               performs no duties (whether or not such period occurs in a single
               Plan Year); provided further, that no hours of service shall be
               credited for payment which is made or due under a program
               maintained solely for the purpose of complying with applicable
               Workers' Compensation, unemployment compensation, or disability
               insurance laws; and provided further, that no hours of service
               shall be credited to an Employee for payment which is made or due
               solely as reimbursement for medical or medically-related expenses
               incurred by him;

                     (c) each hour for which back pay, irrespective of
               mitigation of damages, is either awarded or agreed to by an
               Employer or a Related Corporation; provided, however, that the
               crediting of hours of service for back pay awarded, or agreed to,
               with respect to a period of employment or absence from employment
               described in any other paragraph of this Section 2.1 shall be
               subject to the limitations set forth therein and, if applicable,
               in Section 2.2; and

                     (d) each hour for which he would have been scheduled to
               work for an Employer or a Related Corporation during the period
               of time that he is absent from work because of service with the
               armed forces of the United States, but only if he returns to work
               within the period during which he retains reemployment rights
               pursuant to federal law, up to a maximum of

                                       13
<PAGE>

               eight hours per day and 40 hours per week; provided, however,
               that Hours of Service credited under this paragraph (d), when
               added to hours of service credited under paragraph (b), if any,
               by reason of such absence, shall not exceed a total of 1,000
               Hours of Service for any one Plan Year.

Notwithstanding anything to the contrary contained in this Section 2.1, no more
than one Hour of Service shall be credited to an Employee for any one hour of
his employment or absence from employment.

               2.2   DETERMINATION OF NON-DUTY HOURS OF SERVICE. In the case of
a payment which is made or due from an Employer or a Related Corporation on
account of a period during which an Employee performs no duties, and which
results in the crediting of hours of service under paragraph (b) of Section 2.1,
or in the case of an award or agreement for back pay, to the extent that such
award or agreement is made with respect to a period described in such paragraph
(b), the number of Hours of Service to be credited shall be determined as
follows:

                     (a) In the case of a payment made or due which is
               calculated on the basis of units of time, such as hours, days,
               weeks, or months, the number of Hours of Service to be credited
               shall be the number of regularly scheduled working hours included
               in the units of time on the basis of which the payment is
               calculated.

                     (b) In the case of a payment made or due which is not
               calculated on the basis of units of time, the number of Hours of
               Service to be credited shall be equal to the amount of the
               payment divided by the Employee's most recent hourly rate of
               compensation immediately prior to the period to which the payment
               related.

                     (c) Notwithstanding the provisions of paragraphs (a) and
               (b), no Employee shall be credited on account of a period during
               which no duties are performed with a number of Hours of Service
               which is greater than the number of regularly scheduled working
               hours during such period.

                     (d) If an Employee is without a regular work schedule, the
               number of "regularly scheduled working hours" shall mean the
               average number of hours worked by Employees in the same job
               classification during the period to which the payment relates, or
               if there are no other Employees in the same job classification,
               the average number of hours worked by the Employee during an
               equivalent, representative period.

                                       14
<PAGE>

For the purpose of crediting Hours of Service under paragraph (b) of Section
2.1, a payment shall be deemed to be made by or due from the Employer (i)
regardless of whether such payment is made by or due from an Employer or a
Related Corporation directly, or indirectly through (among others) a trust fund
or insurer to which the Employer contributes or pays premiums, and (ii)
regardless of whether contributions made or due to such trust fund, insurer, or
other entity are for the benefit of particular persons or are on behalf of a
group of persons in the aggregate.

               2.3   ALLOCATION OF HOURS OF SERVICE TO PLAN YEARS. Hours of
Service credited under Section 2.1 shall be allocated to the appropriate Plan
Year in the following manner:

                     (a) Hours of Service described in paragraph (a) of Section
               2.1 shall be allocated to the Plan Year or Years in which the
               duties are performed.

                     (b) Hours of Service described in paragraph (b) of Section
               2.1 shall be allocated as follows:

                           (i) Hours of Service credited to an Employee on
                     account of a payment which is calculated on the basis of
                     units of time, such as hours, days, weeks, or months, shall
                     be allocated to the Plan Year or Years in which the period
                     during which no duties are performed occurs, beginning with
                     the first unit of time to which the payment relates; and

                           (ii) Hours of Service credited to an Employee on
                     account of a payment which is not calculated on the basis
                     of units of time shall be allocated to the Plan Year in
                     which the period during which no duties are performed
                     occurs, or if such period extends beyond a Plan Year, such
                     Hours of Service shall be allocated equally between the
                     first two such Plan Years.

                     (c) Hours of Service described in paragraph (c) of Section
               2.1 shall be allocated to the Plan Year or Years to which the
               award or agreement for back pay pertains, rather than to the Plan
               Year in which the award, agreement, or payment is made.

                     (d) Hours of Service described in paragraph (d) of Section
               2.1 shall be allocated to the Plan Year or Years during which
               such absence occurred.

                   EMPLOYEE PARTICIPATION AND VESTING SERVICE
                   ------------------------------------------

               3.1   PARTICIPATION. Each Employee who is a Participant on
January 1, 1995, shall continue to be a Participant in the Plan. Each other
Employee who does not waive participation in the Plan shall become a Participant
as of the 31st day after he completes an Hour of Service.

               3.2   NEW PARTICIPANTS. Upon becoming a Participant hereunder, an
Employee shall be entitled to benefits under the Plan and shall be bound by all
provisions of the Plan. Each such Employee may file with the Company a written
election on a form and in a manner prescribed by the Company containing the
following information:

                     (a) His authorization for his Employer to deduct
               Participant Contributions from his Compensation pursuant to the
               provisions of Section 4.3; and

                     (b) His election as to the investment of his Company
               Contributions, Tax Deferred Contributions, and Participant
               Contributions pursuant to the provisions of Articles VI and VII.

               3.3YEARS OF SERVICE. For the purposes of the Plan, Years of
Service shall be determined in accordance with the following provisions:
                     (a)   An Employee shall be credited with a Year of Service
                     for each Plan Year in which he completes at least 1,000
                     Hours of Service.

                     (b)   In the case of an Employee who has a Break in
                     Service:

                           (i) if an Employee did not have a nonforfeitable
                     right to any portion of his Separate Account attributable
                     to Company Contributions before his Break in Service
                     commenced, Years of Service with an Employer or a Related
                     Corporation prior to the Break in Service shall be
                     disregarded for purposes hereof if the number of
                     consecutive one-year Breaks in Service is greater than five
                     or is at least equal to the aggregate number of Years of
                     Service with which the Employee had been credited prior to
                     such Break in Service (such aggregate number of Years of
                     Service shall not include any Years of Service not required
                     to be taken into account due to previous Breaks in
                     Service); and

                                       16
<PAGE>

                           (ii) if an Employee's Years of Service are not
                     excluded under (i) above or if the Employee had a
                     nonforfeitable right to any portion of his Account
                     attributable to Company Contributions before his Break in
                     Service commenced, his Years of Service before the Break in
                     Service commenced shall be reinstated upon his again
                     completing an Hour of Service as an Employee.

               3.4   CHANGES IN EMPLOYMENT STATUS; TRANSFERS OF EMPLOYMENT. If a
Participant ceases to be an Employee but continues in the employment of an
Employer or a Related Corporation in some other capacity, he shall nevertheless
continue his participation in the Plan as an inactive Participant until his
participation is otherwise terminated in accordance with the provisions of the
Plan; provided, however, that such Participant shall share in Company
Contributions for any Plan Year of such participation only on the basis of his
Compensation as an Eligible Employee during such Plan Year. Moreover, if a
person is transferred directly from employment (a) with an Employer in a
capacity other than as an Employee, or (b) with a Related Corporation to
employment with an Employer as an Employee, his Hours of Service with the
Employer or such Related Corporation shall be included in determining his Years
of Service under Section 3.3.

               3.5   REEMPLOYMENT OF A PARTICIPANT. If a retired or former
Participant is reemployed by an Employer or a Related Corporation after he
incurs a Settlement Date and if his Years of Service are reinstated pursuant to
the provisions of Section 3.3, he shall again become a Participant on the date
he is reemployed by an Employer; provided, however, that if he is not reemployed
as an Employee, he shall again become a Participant on the first day thereafter
on which he does become an Employee. If a former Participant who incurs a
Settlement Date under Section 10.1 is thereafter reemployed as an Employee and
if his Years of Service are not reinstated pursuant to the provisions of Section
3.3, he shall become a Participant as of the first day of the calendar month
after he meets the eligibility requirements set forth in Section 3.1.

                                  CONTRIBUTIONS
                                  -------------

               4.1   COMPANY CONTRIBUTIONS. The Employers may make a Company
Contribution in cash or in kind, including OMG Stock, for each Plan Year which
shall be an amount determined by the Board of Directors of each Employer, in its
discretion, by written action specifying the amount and the Plan Year for which
it is being made. Subject to the provisions of Sections 5.6 and 15.7, such
Company Contribution shall be deemed to be made as of the last day of the Plan
Year for which it is made and shall be allocated pursuant to Section 4.6.

               4.2.  CASH OPTION ELECTION AND TAX DEFERRED CONTRIBUTIONS. Except
as otherwise provided in Article V, a Participant who has a portion of a Company
Contribution allocated to him pursuant to clause (a) of Section 4.6, may elect
annually to receive 50 percent of such allocation in cash. Such election shall
be known as the Cash Option Election and shall be made in such form, time and
manner as specified by the Company. In the event a Participant does not make
such election, the amount that could have been paid to him shall be referred to
as Tax Deferred Contributions and credited to his Cash Option Account.
Notwithstanding the foregoing, in no event shall the Tax Deferred Contributions
of a Participant under the Plan and all other elective deferrals made pursuant
to Section 402(g) of the Code under all other qualified plans maintained by the
Company and Related Corporations during a calendar year exceed $7,000 (or such
higher dollar limit as shall be in effect for calendar year in accordance with
the adjustment factor prescribed under Section 402(g)(5) and 415(d) of the
Code).
               4.3   PARTICIPANT CONTRIBUTIONS. Commencing with the date as of
which an Eligible Employee becomes a Participant, such Participant may elect to
make Participant Contributions by payroll deduction, or by direct payment in the
form, time and manner specified by the Company, in an amount which does not
exceed ten percent of his Compensation. Any payroll deduction with respect to
Participant Contributions shall be made from a Participant's Compensation by his
Employer in accordance with the terms of a Compensation deduction

                                       18
<PAGE>

authorization completed and filed in such form, time, and manner as specified by
the Company.

               4.4   CHANGES IN PARTICIPANT CONTRIBUTIONS. Any Participant may
elect to change the percentage of his Compensation which he contributes to the
Plan as Participant Contributions or suspend his Participant Contributions. Such
election shall be made in such form, time, and manner as specified by the
Company and shall be subject to the limitations set forth in Section 4.3.
Participant Contributions shall be made on behalf of such Participant by his
Employer, pursuant to the amended Compensation deduction authorization filed in
accordance with the foregoing provisions of this Section 4.4, until otherwise
altered or terminated in accordance with the Plan.

               4.5   EXCESS TAX DEFERRED CONTRIBUTIONS. In the event a
Participant who had Tax Deferred Contributions made on his behalf for a taxable
year files with the Company, within the time limit prescribed by the Company
after the end of such year, a written statement that he has elective deferrals
within the meaning of Section 402(g) of the Code for the taxable year in excess
of the dollar limitation on elective deferrals in effect for such taxable year,
and specifying the amount of such excess the Participant claims as allocable to
this Plan, the amount of such excess, adjusted for income or loss attributable
to such excess elective deferrals, shall be distributed to the Participant by
April 15 of the year following the year of the excess elective deferral.

               4.6   ALLOCATION OF COMPANY CONTRIBUTIONS. Any Company
Contribution made by an Employer pursuant to Section 4.1 shall be allocated
among Participants of such Employer who are Participants as of the last day of
the Plan Year for which such Company Contribution is contributed and who have
completed at least 1,000 Hours of Service during such Plan Year and to all
Participants who terminated employment at or after attainment of age 65, became
permanently and totally disabled, or died during such Plan Year. Such allocation
shall be (a) made in the ratio which the Compensation of each such Participant
for such Plan Year bears to the aggregate Compensation of all such designated
Participants of such Employer for such preceding Plan Year, minus (b) the
amount, if any, that the Participant elected to receive in cash

                                       19
<PAGE>

pursuant to the Cash Option Election under Section 4.2.

               4.7   ROLLOVER CONTRIBUTIONS. In accordance with procedures
established by the Company, a Participant who has rollover contributions
described in Section 402(a)(5), Section 403(a)(4), Section 403(b)(8), or Section
408(d)(3)(A) of the Code, may elect to make a Rollover Contribution to the Plan
by delivering, or causing to be delivered, to the Trustee the assets in cash
which constitute such Rollover Contribution at such time or times and in such
manner as shall be specified by the Company. Upon receipt by the Trustee, such
assets shall be deposited in the Fund or Funds selected by the Participant in
accordance with an investment election filed with the Company by such
Participant. Such election shall specify a combination in five percent
increments which, in the aggregate, equals 100 percent. The investment option so
selected by a Participant shall remain in effect until he elects to change such
election in accordance with Section 6.4 or receives distribution of his Accounts
pursuant to Section 10.4. As of the date of receipt of such property by the
Trustee, a Rollover Account shall be established in the name of the Participant
who has made a Rollover Contribution as provided in this Section 4.7 and shall
be credited with such assets on such date. A Rollover Contribution by a
Participant pursuant to this Section 4.7 shall not be deemed to be a
contribution of such Participant for any purpose of the Plan and shall be fully
vested in the Employee at all times.

               4.8   TRANSFERRED CONTRIBUTIONS. In accordance with procedures
established by the Company, any Participant who was previously a participant in
a plan qualified under Section 401 of the Code (any such plan being hereinafter
referred to as a transferor plan) may request the Company to arrange for the
transfer to the Trustee of Transferred Contributions, which are funds held by
the funding agent of such transferor plan representing the Participant's vested
account balance thereunder; provided, however, that such transfer shall be made
in such manner and at such time as shall be specified by the Company; and
provided further, that no such transfer shall be permitted from a transferor
plan on behalf of a Participant who was at any time a five percent owner of the
employer maintaining such transferor plan or from a transferor plan which is

                                       20
<PAGE>

subject to the joint and survivor annuity requirements under Section 401(a)(11)
of the Code; and provided further, that any Transferred Contributions which were
subject to restrictions on withdrawal pursuant to Section 401(k) of the Code
under the transferor plan shall continue to be subject to such restrictions upon
transfer to the Trustee. The Trustee shall deposit all Transferred Contributions
received by it in the Trust, and shall credit the respective Rollover Account of
the Participant on whose behalf such funds were transferred in accordance with
the provisions of Section 4.7 applicable to Rollover Contributions. The portion
of the Rollover Account of a Participant attributable to Transferred
Contributions shall be fully vested in the Participant at all times.

               4.9   DELIVERY OF CONTRIBUTIONS. Each Employer shall cause to be
delivered to the Trustee all Company Contributions, Tax Deferred Contributions,
Participant Contributions, Rollover Contributions, and Transferred Contributions
made in accordance with the provisions of this Article IV as soon as reasonably
practicable; provided, however, that Company Contributions and Tax Deferred
Contributions for any Plan Year shall be paid to the Trustee within the period
of time established by the Code in order that such contributions shall be
deductible by the Employers in computing federal income taxes for such Plan
Year.

               4.10  CREDITING OF CONTRIBUTIONS. Subject to the provisions of
Appendix A, the Accounts of each Participant shall be credited with his Tax
Deferred Contributions, Company Contributions, Participant Contributions,
Rollover Contributions and Transferred Contributions for such Plan Year
allocated to him under this Article IV.

                           LIMITATION ON CONTRIBUTIONS
                           ---------------------------

              5.1 LIMITATION ON TAX DEFERRED CONTRIBUTIONS AND PARTICIPANT
CONTRIBUTIONS. Notwithstanding any other provision of the Plan to the contrary,
the Company shall take such action as it deems appropriate to limit the amount
of Tax Deferred Contributions and Participant Contributions under the Plan made
on behalf of each Highly Compensated Employee for each Plan Year to the extent
necessary to insure that the actual deferral percentage requirement and average
contribution percentage requirement under Sections 401(k) and 401(m) of the

                           who are eligible to have amounts contributed to the
                           Plan on their behalf for the Plan Year, including

                                  (1)   If the Related Plans are subject to the
                                        ADP or the ACP Test, and are considered
                                        as one plan for purposes of Sections
                                        401(a)(4) or 410(b) of the Code, all
                                        such plans shall be aggregated and
                                        treated as one plan for purposes of
                                        meeting the ADP Test and the ACP Test,
                                        provided that plans may only be
                                        aggregated if they have the same Plan
                                        Year.

                                  (2)   If a HCE has any Family Members, the
                                        Deferrals,

                                       23
<PAGE>

                                        Contributions and Compensation of such
                                        HCE and his or her Family Members shall
                                        be combined and treated as those of a
                                        single HCE. In addition, such amounts
                                        for all other Family Members shall be
                                        removed from the NHCE Group Average
                                        Percentage calculation and be combined
                                        with the Average Percentage calculation
                                        of the HCE Group if the calculated
                                        percentages used in calculating the ADP
                                        and ACP for the HCE Group would
                                        increase, or not be used in the ADP Test
                                        or the ACP Test.

                                  (3)   If a HCE is covered by more than one
                                        cash or deferred arrangement under the
                                        Related Plans, all such plans (other
                                        than plans that are not required to be
                                        aggregated under Treas. Reg. Section
                                        1.401(k)- 1(g)(1)(ii)(B)) shall be
                                        aggregated and treated as one plan for
                                        purposes of calculating the separate
                                        percentage for such HCE which is used in
                                        the determination of the Average
                                        Percentage.

                      (m)  The term "RELATED PLAN" shall mean (a) with respect
                           to Section 415 of the Code, any other defined
                           contribution plan or a defined benefit plan (as
                           defined in Section 415(k) of the Code) maintained by
                           a Related Corporation, and (b) with respect to
                           Section 401(k) and 401(m) of the Code, any plan or
                           plans maintained by a Related Corporation which is
                           treated with the Plan as a single plan for purposes
                           of Section 401(a)(4) or 410(b) of the Code (other
                           than Section 410(b)(2)(A)).

              5.3 ADJUSTMENT OF ADP AND ACP TESTS. If the ADP or ACP Tests under
Section 401(k) and Section 401(m) of the Code, respectively, are not met, the
Company shall determine a maximum percentage to be used in place of the
calculated percentage for each HCE that would reduce the ADP and/or ACP of the
HCE Group by a sufficient amount to meet the ADP and ACP Tests. For any HCE
Group who has a Family Member, the reduction amount shall be prorated among
Family Members as provided in Sections 401(k) and (m) of the Code.
                     (1)   ADP CORRECTION. Deferrals shall be refunded
                           (including amounts previously refunded because they
                           exceeded the Contribution Dollar Limit) to the
                           Participant by the end of the next Plan Year in an
                           amount equal to the actual Deferral minus the product
                           of the maximum percentage for that HCE and the HCE's
                           Compensation. If Tax Deferred Contributions are

                                       24
<PAGE>

                           distributed more than 2-1/2 months after the end of
                           the Plan Year, an excise tax equal to ten percent of
                           such excess Tax Deferred Contributions will be
                           imposed on the Company. Excess Tax Deferred
                           Contributions shall be treated as Annual Additions
                           for purposes of Appendix A.

                     (2)   ACP CORRECTION. Contribution amounts in excess of the
                           maximum percentage of an HCE's Compensation shall, by
                           the end of the next Plan Year, be refunded to the
                           Participant.

                     (3)   INVESTMENT FUND SOURCES. Once the amount of excess
                           Deferrals and/or Contributions is determined by type
                           of Contribution, amounts shall then be taken by type
                           of investment in direct proportion to the market
                           value of the Participant's interest in each Fund as
                           of the Valuation Date as of which the correction is
                           processed.

                     (4)   FAMILY MEMBER CORRECTION. To the extent any reduction
                           is necessary with respect to an HCE and his or her
                           Family Members that have been combined and treated
                           for testing purposes as a single Employee, the excess
                           Contributions from the ADP Test and/or ACP Test shall
                           be prorated among each such Participant in direct
                           proportion to his or her Deferrals or Contributions
                           included in each test.

The Company shall determine the maximum percentage for each HCE whose calculated
percentage is the highest at any one time by reducing his calculated percentage
in the following manner until the ADP Test and/or the ACP Test are satisfied:
                     (a)   The calculated percentage for each HCE under a
                           Related Plan shall be reduced to the extent permitted
                           under such Related Plan.

                     (b)   If more reduction is needed, the calculated
                           percentage of each HCE whose calculated percentage is
                           the greatest shall be reduced by 1/100th of one
                           percentage point.

                     (c)   If more reduction is needed, the calculated
                           percentage of each HCE whose calculated percentage is
                           the greatest (including the calculated percentage of
                           any HCE whose calculated percentage was adjusted
                           under subparagraph (b) above shall be reduced by
                           1/100th of one percentage point.

                     (d)   If more reduction is needed, the procedures of
                           subparagraph (c) shall be repeated.

                                       25

              5.4 MULTIPLE USE TEST. If the sum of the ADP and ACP for the HCE
Group exceeds the aggregate limit under Treas. Reg. Section 1.401(m)-2(b)(3) and
the ADP for the HCE Group is more than 125 percent of the ADP for the NHCE Group
and the ACP for the HCE Group is more than 125 percent of the ACP of the NHCE
Group, the ADP and ACP for the HCE Group must also comply with the requirements
of Section 401(m)(9) of the Code, which require that the sum of these two
percentages (as determined after any corrections needed to meet the ADP Test or
ACP Test have been made) must not exceed the greater of:
                     (a)   the sum of

                           (1)    the larger of the ADP or ACP for the NHCE
                                  Group times 1.25; and

                           (2)    the smaller of the ADP or ACP for the NHCE
                                  Group, times two if the NHCE Average
                                  Percentage is less than two percent, or plus
                                  two percent if it is two percent or more; or

                     (b)   the sum of

                           (1)    the lesser of the ADP or ACP for the NHCE
                                  Group times 1.25; and

                           (2)    the greater of the ADP or ACP for the NHCE
                                  Group, times two if the NHCE Average
                                  Percentage is less than two percent, or plus
                                  two percent if it is two percent or more.

If the multiple use limit is exceeded, the Company shall determine a maximum
percentage to be used in place of the calculated percentage for each HCE that
would reduce either or both the ADP or ACP for the HCE Group by a sufficient
amount to meet the multiple use limit. Any excess shall be treated in the same
manner that excess Contributions are treated.

              5.5 ADJUSTMENT FOR INVESTMENT GAIN OR LOSS. The net investment
gain or loss associated with the excess Deferral or Contribution amount shall be
distributed or forfeited in the same manner as the excess amount. Such gain or
loss is calculated as follows:
               E x  G  x (1 + (10% x M))
                   ---
               (AB-G)

                                       26
<PAGE>

where:

               E =     the total excess Deferrals or Contributions,

               G =     the net gain or loss for the Plan Year from all of a
                       HCE's affected Accounts,

               AB =    the total value of a HCE's affected Accounts,
                       determined as of the end of the Plan Year being
                       corrected,

               M  =    the number of full months from the Plan Year end to the
                       date excess amounts are paid, plus one for the month
                       during which payment is to be made if payment will occur
                       after the 15th day of the month.

              5.6 LIMITATIONS ON COMPANY CONTRIBUTIONS AND TAX DEFERRED
CONTRIBUTIONS. The sum of Company Contributions and Tax Deferred Contributions
for any Plan Year in no event shall exceed (i) the maximum amount which will
constitute an allowable deduction for such year to the Employers under Section
404 of the Code, (ii) the maximum amount which may be contributed by the
Employers under Section 415 of the Code, or (iii) the maximum amount which may
be contributed pursuant to any regulation, ruling, or order issued pursuant to
law.

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

               6.1   DEPOSIT OF CONTRIBUTIONS. All Company Contributions

                                   ARTICLE VII

              MAINTENANCE OF FUNDS AND INVESTMENT OF CONTRIBUTIONS
              ----------------------------------------------------

               7.1   ESTABLISHMENT AND MAINTENANCE OF FUNDS. The Company shall
cause at least three Funds to be established and maintained at all times. With
the exception of the OMG Stock Fund, each such Fund will be diversified and have
different risk and return characteristics from the other Funds. The OMG Stock
Fund and any Fund which invests in investments with restrictions regarding Funds
to which investment transfers may be made or to which a minimum investment
period is applicable shall not be considered as one of such requisite three
Funds.
               7.2   INCOME ON FUNDS. Unless specifically provided otherwise,
any dividends, interest, distributions, or other income received in respect of a
Fund shall be reinvested in the Fund with respect to which such income was
received by it.

               7.3   ACCOUNTS AND SUBACCOUNTS. Accounts and subaccounts shall be
established in the name of each Participant. Such Accounts and subaccounts shall
be dependent upon the Funds in which contributions are invested on his behalf
under the Plan and upon the type of contributions so invested on his behalf, and
shall be maintained and administered for each Participant in accordance with the
provisions of the Plan.

               7.4   INVESTMENT ELECTIONS. Each Participant, upon becoming a
Participant under the Plan in accordance with the provisions of Section 3.1,
shall make an investment election directing the manner in which his Company
Contributions, Tax Deferred Contributions and Participant Contributions, shall
be invested in the Funds. The investment election of a Participant shall specify
a combination, in five percent increments, which in the aggregate equals 100
percent, indicating in which Funds his Company Contributions and Tax Deferred
Contributions shall be invested and a combination, in five percent increments,
which in aggregate equals 100 percent, indicating in which Funds his Participant
Contributions shall be invested. The investment option so elected by a
Participant shall remain in effect until he changes his investment election
pursuant to Section 6.3 or receives distribution of his Account pursuant to
Section 10.4. As of the first day

                                       30
<PAGE>

of a calendar year quarter, a Participant may change his investment election
with respect to future contributions and/or past contributions by filing the
appropriate form with the Company in the form, manner, and time prescribed by
the Company.

               7.5   INVESTMENT RESPONSIBILITY. The Plan is intended to
constitute a plan described in Section 404(c) of ERISA and DOL Regs. Section
2550.404c-1 and insofar as the Plan complies with said Section 404(c), Plan
fiduciaries shall be relieved of liability for any losses which are the direct
result of investment instructions given by Participants and Beneficiaries.
Notwithstanding the foregoing, to the extent that Section 404(c) of ERISA is not
applicable, Participants shall be named fiduciaries with respect to the
investment of their Separate Accounts.

               7.6   VOTING OF OMG STOCK. Each Participant who has shares of OMG
Stock allocated to his Accounts shall be a named fiduciary with respect to the
voting of such OMG Stock and shall have the following powers and
responsibilities:
                    (a) Prior to each annual or special meeting of the
               shareholders of the Company, the Company shall cause to be sent
               to each Participant, and Beneficiary who has OMG Stock allocated
               to his Accounts under the OMG Stock Fund or credited to him under
               the Plan a copy of the proxy solicitation material therefor,
               together with a form requesting confidential voting instructions,
               with respect to the voting of such OMG Stock as well as the
               voting of OMG Stock for which the Trustee does not receive
               instructions. Each such Participant and Beneficiary shall
               instruct the Trustee to vote the number of such uninstructed
               shares of OMG Stock equal to the proportion that the number of
               the shares of OMG Stock allocated to his Accounts bears to the
               total number of shares of OMG Stock in the OMG Stock Fund for
               which instructions are received. Upon receipt of such a
               Participant's or Beneficiary's instructions, the Trustee shall
               then vote in person, or by proxy, such OMG Stock as so
               instructed.

                    (b) The Company shall cause the Trustee to furnish to each
               Participant and Beneficiary who has OMG Stock credited to his
               Accounts under the OMG Stock Fund or credited to him under the
               Plan notice of any tender or exchange offer for, or a request or
               invitation for tenders or exchanges of, OMG Stock made to the
               Trustee. The Trustee shall request from each such Participant and
               Beneficiary instructions as to the tendering or exchanging of OMG
               Stock allocated to his Accounts or credited to him as well as the
               tendering or exchanging of OMG Stock for which the Trustee does
               not receive instructions. Each such Participant, and

                                       31
<PAGE>

               Beneficiary shall instruct the Trustee with respect to the
               tendering or exchanging of the number of such uninstructed shares
               of OMG Stock equal to the proportion that the number of the
               shares of OMG Stock allocated to his Accounts bears to the total
               number of shares of OMG Stock in the OMG Stock Fund for which
               instructions are received. The Trustee shall provide such
               Participants and Beneficiaries with a reasonable period of time
               in which they may consider any such tender or exchange offer for,
               or request or invitation for tenders or exchanges of, OMG Stock
               made to the Trustee. Within the time specified by the Trustee,
               the Trustee shall tender or exchange such OMG Stock as to which
               the Trustee has received instructions to tender or exchange from
               Participants and Beneficiaries.

                    (c) Instructions received from Participants and
               Beneficiaries by the Trustee regarding the voting, tendering, or
               exchanging of OMG Stock shall be held in strictest confidence and
               shall not be divulged to any other person, including officers or
               employees of the Company, except as otherwise required by law,
               regulation or lawful process.

               7.7   ACCOUNT BALANCES. For all purposes of the Plan, the balance
of each Account and subaccount of a Participant as of any date shall be the
balance of each such Account and subaccount after all credits and charges
thereto, for and as of such date, have been made as provided in the Plan.

                                   VALUATIONS
                                   ----------

               8.1 VALUATION OF PARTICIPANT'S INTEREST. As of each Valuation
Date hereunder, the Company shall adjust each Account of each Participant to
reflect any increase or decrease in net worth of the Funds hereunder since the
immediately preceding Valuation Date, based on the valuation of each Fund by the
Trustee and determined in the following manner:

                    (a) The Trustee shall value all of the assets of each of the
               Funds at fair market value.

                    (b) The Trustee shall then, on the basis of such valuation,
               and after making appropriate adjustments for the amount of all
               contributions made with respect to the quarter in which such
               Valuation Date occurs, for any distributions and withdrawals to
               or from the respective Funds since the immediately preceding
               Valuation Date and prior to such date and for any transfers from
               or to the respective Funds since the immediately preceding
               Valuation Date and prior to such date, ascertain the net increase
               or decrease in net worth of the respective Funds which is
               attributable to net earnings and all profits and losses, realized
               and unrealized, since the immediately preceding Valuation Date.

                    (c) The Trustee shall then allocate the net increase or
               decrease in the net worth of the respective Funds as thus
               determined among all Participants, inactive Participants, and
               Beneficiaries who have an interest in the respective Funds,
               separately with respect to each of such Funds, in the ratio that
               the balance of each subaccount maintained under such Fund on the
               day immediately preceding such Valuation Date bears to the
               aggregate of the balances of all such accounts on the day
               immediately preceding such Valuation Date, and shall credit or
               charge, as the case may be, each such subaccount with the amount
               of its allocated share.

                    (d) The Trustee shall then credit to the appropriate
               Accounts and subaccounts of each Participant with his Participant
               Contributions, Rollover Contributions, and Transferred
               Contributions for the Plan Year quarter in which such Valuation
               Date occurs.

                    (e) Then, if the Valuation Date is the last day of the Plan
               Year, the Trustee shall then credit to the appropriate Accounts
               and subaccounts of each Participant, his portion of the Company
               Contributions, Tax Deferred Contributions and forfeitures for the
               Plan Year, which are allocated to such Participant as of such
               Valuation Date pursuant to such Sections 4.6 and 10.8.

               8.2   FINALITY OF TRUSTEE'S DETERMINATION. The Trustee shall have
exclusive responsibility for determining the value of the assets of the Funds
hereunder. The determination thereof by the Trustee shall be conclusive upon the
Employers, the Company, and all Participants and Beneficiaries hereunder.

               8.3   NOTIFICATION. At least annually the Company shall notify
each Participant of the balance of his Accounts as of the last day of such Plan
Year.

                  TERMINATION OF PARTICIPATION AND DISTRIBUTION
                  ---------------------------------------------

               10.1 TERMINATION OF PARTICIPATION. Each Participant shall cease
to be an active Participant hereunder upon his Settlement Date which shall be
the first of the dates to occur hereinafter set forth:

                      (a) the date such Participant's employment with an
               Employer or a Related Corporation is terminated due to normal
               retirement at or after attainment of age 65 which is normal
               retirement age under the Plan;

                      (b) the date such Participant's employment with an
               Employer or a Related Corporation is terminated because of
               physical or mental disability preventing his continuing in the
               service of such Employer or Related Corporation, as determined by
               the Company upon the basis of a written certificate of a
               physician selected by it;

                      (c) the date such Participant's employment with an
               Employer or a Related Corporation is terminated because of the
               death of such Participant; or

                      (d) the date such Participant's employment with an
               Employer or a Related Corporation is terminated under any other
               circumstances.

Notwithstanding any other provision of the Plan to the contrary, a Participant's
right to receive distribution of the balance of each of his Accounts as of his
Settlement Date, in accordance with the provisions of this Article X, shall be
fully vested and nonforfeitable upon attainment of age 65.

               10.2 VESTING. A Participant whose employment terminates in
accordance with paragraph (a), (b) or (c) of Section 10.1 shall be fully vested
in the balance of each of his Accounts. A Participant whose employment
terminates in accordance with paragraph (d) of Section 10.1 prior to attainment
of age 65 shall be 100% vested in the balance of his Cash Option Account, Thrift
Account and Rollover Account and shall be vested in the balance of his Company
Contribution Account in accordance with the schedule applicable to him set forth
below:
               YEARS OF SERVICE     VESTED PERCENTAGE
               ----------------     -----------------

               Less than one                             0%
               One but less than two                    10%

               Four but less than five                  40%
               Five or more                            100%

Any unvested portion of such Accounts shall be governed by the provisions of
Section 10.8. Notwithstanding any other provision of the Plan to the contrary,
the portion of the Company Contribution for the 1995 Plan Year which is
allocated to the Company Contribution Account of each Participant who is not a
Highly Compensated Employee and which is equal to .5% of such Participant's
Compensation shall be 100% vested in such Participant.

            10.3 ELECTION OF FORMER VESTING SCHEDULE. In the event the Company
adopts an amendment to the Plan that directly or indirectly affects the
computation of a Participant's nonforfeitable interest in his Account
attributable to Company Contributions, any Participant with three or more Years
of Service shall have a right to have his nonforfeitable interest in such
accounts continue to be determined under the vesting schedule in effect prior to
such amendment rather than under the new vesting schedule, unless the
nonforfeitable interest of such Participant in such accounts under the Plan, as
amended, at any time is not less than such interest determined without regard to
such amendment. A Participant shall exercise such right by giving written notice
of his exercise thereof to the Company within 60 days after the latest of (i)
the date he received notice of such amendment from the Company, (ii) the
effective date of the amendment, or (iii) the date the amendment is adopted.
Notwithstanding the foregoing provisions of this Section 10.3, the vested
interest of each Participant on the effective date of such amendment shall not
be less than his vested interest under the Plan as in effect immediately prior
to the effective date thereof.

            10.4 DISTRIBUTION. Except as otherwise set forth below with respect
to certain Accounts, the Company shall direct the Trustee to make distribution
to or for the benefit of a Participant, who incurs a Settlement Date pursuant to
the provisions of Section 10.1, from his interest under the Plan which, on any
date, shall be equal to the balance of his Accounts as of such date. Such
distribution shall be made in a single lump-sum payment or installments payment

                                       38

payable to such Participant at such time and manner as set forth in procedures
adopted by the Company. Subject to the provisions of Section 10.12, distribution
hereunder shall be made or commenced as soon as reasonably practicable after
such Participant's Settlement Date, but unless otherwise elected by the
Participant, in no event later than 60 days after the latest of the close of the
Plan Year in which:
                     (i)   such Participant attains age 65,

                     (ii)  the tenth anniversary of the year in which such
                           Participant commenced participation in the Plan
                           occurs, or

                     (iii) such Participant incurs a Settlement Date.

In the event such Participant fails to consent to a distribution, such failure
shall be deemed to be an election to defer the payment of any benefits
sufficient to satisfy this Section 10.4 and payment of his benefit shall not
occur until the earlier of the receipt of his application for distribution or
his Mandatory Distribution Date. Notwithstanding the foregoing, if at the time
benefits are distributable under the preceding sentence, the balance credited to
a Participant's Accounts exceed $3,500, benefits shall be paid only if the
Participant consents in writing to such distribution not more than 90 days
before commencement of distribution.

            10.5 FORM OF DISTRIBUTION. All distributions under the provisions of
this Article X made to a Participant or to a Beneficiary shall be made in cash
unless the Participant or Beneficiary elects to receive any interest of his
Accounts invested in the OMG Stock Fund in OMG Stock.

            10.6 RESTRICTION ON ALIENATION. Except as provided in Sections
401(a)(13)(B) and 414 (p) of the Code relating to qualified domestic relations
orders, no benefit under the Plan at any time shall be subject in any manner to
anticipation, alienation, assignment (either at law or in equity), encumbrance,
garnishment, levy, execution, or other legal or equitable process. No person
shall have power in any manner to anticipate, transfer, assign (either at law or
in equity), alienate, or subject to attachment, garnishment, levy, execution, or
other legal or equitable process, or in any way encumber his benefits under the
Plan, or any part thereof, and any attempt to do so shall be

                                       39
<PAGE>

void.

            10.7 REEMPLOYMENT OF FORMER PARTICIPANT. If a former Participant is
reemployed by an Employer, he shall be treated as a new Employee for all
purposes of the Plan, subject to the provisions hereof relating to the
reinstatement of Years of Service.

            10.8 DISPOSITION OF FORFEITED BALANCES. Whenever a distribution is
made with respect to a former Participant of his vested interest in his Company
Contribution Account in accordance with the provisions of Sections 10.2 and
10.5, that portion of the balance of his Company Contribution Account which is
not distributed to him shall be governed by the following provisions.

                     (a)   The unvested portion of such a Participant's Company
                           Contribution Account shall be forfeited at the
                           earlier of the following:

                           (i)    the date on which the Participant's entire
                                  vested interest in his Accounts is distributed
                                  in a single sum or is considered distributed
                                  under paragraph (c) below; or

                           (ii)   the end of the fifth consecutive Break in
                                  Service.

                     (b)   Forfeitures shall be allocated as of the last day of
                           the Plan Year in which the forfeiture occurs to the
                           Company Contribution Accounts of Participants who
                           were Participants on the last day of the prior Plan
                           Year and who are eligible to receive an allocation of
                           Company Contributions for such Plan Year. Such
                           allocation shall be made in the same proportion as
                           each such Participant's Compensation for such Plan
                           Year bears to the aggregate Compensation of all such
                           Participants for such Plan Year.

                     (c)   A zero invested balance of a Participant shall be
                           treated as though it were distributed immediately
                           when employment terminates.

                     (d)   If a Participant is reemployed prior to five
                           consecutive Breaks in Service but after a forfeiture
                           under paragraph (a) above because of an imputed or
                           full distribution, the forfeited amount, unadjusted
                           for interim gains or losses, shall be subject to
                           restoration under paragraphs (f) and (g). No
                           restoration shall occur, if reemployment occurs after
                           five consecutive Breaks in Service or repayment does
                           not occur under paragraph (g).

                                       40
<PAGE>

                     (e)   If a Participant who is not 100% vested in his
                           Company Contribution Account, receives a distribution
                           of the vested portion of his Company Contribution
                           Account prior to incurring five consecutive Breaks in
                           Service with the exception of distributions under
                           paragraph (a)(i) or (c) above, the vested portion of
                           his Company Contribution Account at any time prior to
                           five consecutive Breaks in Service shall not be less
                           than an amount (X) determined in the following
                           manner: X = P(AB + D) - D. For purposes hereof, P is
                           the vested percentage at the relevant time; AB is the
                           balance of the Company Contribution Account at the
                           relevant time; and D is the amount of distributions.

                     (f)   An amount subject to restoration under paragraph (d)
                           shall be credited to the Participant's Company
                           Contribution Account upon reemployment and shall be
                           made from the assets of a special contribution of the
                           Company which shall not constitute an "annual
                           addition" within the meaning of Section 415 of the
                           Code.

                     (g)   A reemployed Participant who is rehired under the
                           conditions set forth in paragraph (d) may repay the
                           full amount previously distributed from his partially
                           vested Company Contribution Account as follows:

                           (1)    Repayment shall be made in a single sum.

                           (2)    Repayment may only be made while the
                                  Participant remains employed and may not be
                                  made later than five years after reemployment.

                           (3)    Repayment cannot be made in whole or in part
                                  by rollover from another plan or individual
                                  retirement account.

            10.9 BUY BACK OF FORFEITED AMOUNTS. A Participant who incurs a
forfeiture pursuant to the provisions of Section 10.2 and 10.8 shall have such
forfeited amounts recredited to his Accounts upon his subsequent resumption of
employment covered under the Plan, without adjustment for interim gains or
losses experienced by the Fund or Funds, provided that he repays to the Plan the
full amount of any distribution attributable to Company Contributions that he
received as a result of his prior Settlement Date, and provided further, that
such repayment occurs no later than the earlier of the fifth anniversary of the
end of the Plan Year in which his Break in Service occurred or the earliest
other date permitted by legislation, ruling, or regulation. Funds

                                       41
<PAGE>

required in any Plan Year to recredit the Accounts of a reemployed Participant
with the amounts of prior forfeitures in accordance with the preceding sentence
shall be made by way of a special Plan contribution by the Employers. In the
event of any such repayment and subsequent recrediting of a prior forfeiture,
the portion of such amount replacing Company Contributions shall be credited to
the Accounts of the Participant currently applicable to the Company
Contributions of such Participant.

            10.10 DISTRIBUTION TO OTHER QUALIFIED PLANS. In the event a former
Participant whose interest in the Plan has not been fully distributed becomes an
active participant in a plan qualified under Section 401(a) of the Code
(including a self-employed retirement plan which is exempt from tax under
Section 501(a) of the Code, an annuity plan described in Section 403(a) of the
Code, or a qualified bond purchase plan described in Section 405(a) of the
Code), the Company may direct the Trustee to transfer the amount of such former
Participant's interest in the Plan to any such plan provided that the plan to
receive such transfer authorizes acceptance of such transfer, that assets
transferred shall be held in a separate account, and that the assets transferred
shall not be subject to any forfeiture provisions.

            10.11 FACILITY OF PAYMENT. In the event that it shall be found that
any individual to whom an amount is payable hereunder is incapable of attending
to his financial affairs because of any mental or physical condition, including
the infirmities of advanced age, such amount (unless prior claim therefor shall
have been made by a duly qualified guardian or other legal representative) may,
in the discretion of the Company, be paid to another person for the use or
benefit of the individual found incapable of attending to his financial affairs
or in satisfaction of legal obligations incurred by or on behalf of such
individual. The Trustee shall make such payment only upon receipt of written
instructions to such effect from the Company. Any such payment shall be charged
to the Accounts from which any such payment would otherwise have been paid to
the individual found incapable of attending to his financial affairs and shall
be a complete discharge of any liability therefor.

            10.12 MANDATORY DISTRIBUTIONS. Notwithstanding any other provision
of this Article X, in the event the vested aggregate balance of a Participant's
Accounts which are distributable to him do not exceed $3,500, such balance shall
be distributed to him in a single sum as soon as practicable after the
Settlement Date. If, however, the vested aggregate balance of a Participant's
Accounts exceeds, or at the time of any prior distribution exceeded, $3,500, no
distribution of such balance shall be made to him, unless such Participant
consents in writing to such distribution; provided, however, that, in no event
shall the distribution of the interest of a Participant commence later than such
a Participant's Mandatory Distribution Date or shall the interest of a
Participant be distributed later than his Mandatory Distribution Date and shall
be determined and made in accordance with the proposed regulations under Section
401(a)(9) of the Code, including the minimum distribution incidental benefit
requirements of Section 1.401(a)(9)-2 of the proposed regulations. Accordingly,
the Mandatory Distribution Date of a Participant shall be as follows:

                     (i) The Mandatory Distribution Date of any Participant
            who attains age 70-1/2 on or after January 1, 1988, shall be April
            1, 1990, or the first day of April following the calendar year in
            which such Participant attains age 70-1/2, whichever is later.

                     (ii) The Mandatory Distribution Date of any Participant who
            has attained age 70-1/2 before January 1, 1988, shall be the first
            day of April of the calendar year following the calendar year in
            which the later of such Participant's termination of employment or
            attainment of age 70-1/2 occurs.

In the event that the interest of any Participant in his Accounts is to be
distributed in other than a single lump sum payment, the following minimum
distribution rules shall become applicable on his Mandatory Distribution Date:

                     (1) A Required Minimum Distribution for each calendar year
            beginning with distributions for the first distribution calendar
            year shall be made in the following manner:

                     (i) For calendar years prior to 1989, the quotient obtained
                     by dividing the Mandatory Distribution Value of such a
                     Participant's Accounts by the applicable life expectancy,
                     and if such Participant's spouse is not the Beneficiary,
                     the method of distribution selected must

                                       43
<PAGE>

                     assure that at least 50 percent of the present value of
                     the amount available for distribution is paid within the
                     life expectancy of such Participant.

                     (ii) For 1989 and subsequent calendar years, the quotient
                     obtained by dividing the Mandatory Distribution Value of
                     such a Participant's Accounts by the lesser of (1) the
                     applicable life expectancy or (2) if such Participant's
                     spouse is not the Beneficiary, the applicable divisor
                     determined from the table set forth in Q&A-4 of Section
                     1.401(a)(9)-2 of the proposed regulations under the Code.
                     Distributions after the death of such Participant shall be
                     distributed using the applicable life expectancy referred
                     to in clause (ii)(1), above as the relevant divisor without
                     regard to clause (ii)(2).

                     (2) The Required Minimum Distribution for such a
            Participant's first distribution calendar year must be made on or
            before such Participant's Mandatory Distribution Date. The Required
            Minimum Distribution for other calendar years, including the
            Required Minimum Distribution for the calendar year in which his
            Mandatory Distribution Date occurs, must be made on or before
            December 31 of such calendar year.

                     (3) If such a Participant dies on or after his Mandatory
            Distribution Date, the remaining portion of his Accounts must
            continue to be distributed at least as rapidly as under the method
            of distribution in effect at his death. If however, such a
            Participant dies before his Mandatory Distribution Date,
            distribution of his Accounts must be completed by December 31 of the
            calendar year containing the fifth anniversary of the death of such
            Participant. For purposes of this Section 10.12, the words and
            phrases hereinafter set forth shall have the following meanings:

                     (1) APPLICABLE LIFE EXPECTANCY. The life expectancy (or
                     joint and last survivor expectancy) calculated using the
                     attained age of the Participant (or Beneficiary) as of his
                     birthday in the applicable calendar year reduced by one for
                     each calendar year which has elapsed since the date life
                     expectancy was first calculated.

                     (2) DISTRIBUTION CALENDAR YEAR; FIRST DISTRIBUTION CALENDAR
                     YEAR. A distribution calendar year is a calendar year for
                     which a minimum distribution is required. For distributions
                     beginning before the death of the Participant, the first
                     distribution calendar year is the calendar year immediately
                     preceding the calendar year which contains his Mandatory
                     Distribution Date. For distributions beginning after the
                     death of the Participant, the first distribution calendar
                     year is the calendar year in which distributions are
                     required to begin.

                     (3) LIFE EXPECTANCY. Life expectancy and joint and last
                     survivor

                                       44
<PAGE>

                     expectancy shall be computed by use of the expected return
                     multiples in Tables V and VI of Treas. Reg. Section 1.72-9
                     and shall be recalculated annually with respect to a
                     Participant after the first distribution calendar year.

                     (4)   MANDATORY DISTRIBUTION VALUES OF ACCOUNTS.

                           (i) The balance of the Accounts of a Participant as
                           of the last Valuation Date in the calendar year
                           immediately preceding the distribution calendar year
                           (the "valuation calendar year") increased by the
                           amount of any contributions or forfeitures allocated
                           to the Account balances as of dates in the valuation
                           calendar year after the Valuation Date and decreased
                           by distributions made in the valuation calendar year
                           after the Valuation Date.

                           (ii) For purposes of subparagraph (i), above, if any
                           portion of the minimum distribution for the first
                           distribution calendar year is made in the second
                           distribution calendar year on or before the Mandatory
                           Distribution Date, the amount of such minimum
                           distribution made in the second distribution calendar
                           year shall be treated as if it had been made in the
                           immediately preceding distribution calendar year.

            10.13 ELIGIBLE ROLLOVER DISTRIBUTIONS. Each Participant and
Beneficiary who receives an Eligible Rollover Distribution may elect in the time
and in a manner prescribed by the Company to receive all or any portion of such
Eligible Rollover Distribution for transfer to an Eligible Retirement Plan;
provided, however, that only one such transfer may be made with respect to a
Eligible Rollover Distribution to an Eligible Retirement Plan. Notwithstanding
the foregoing, the Participant may elect, after receiving the notice required
under Section 402(f) of the Code, to receive such Eligible Rollover Distribution
prior to the expiration of the 30-day period beginning on the date such
Participant is issued such notice; provided that the Participant or beneficiary
is permitted to consider his decision for at least 30 days and is advised of
such right in writing.

                                   ARTICLE XI

                                  BENEFICIARIES
                                  -------------

            11.1 DESIGNATION OF BENEFICIARY. In the event of the death of a
Participant or former Participant prior to distribution in full of his interest
under the Plan, the spouse, if any, of such Participant or former Participant
shall be his Beneficiary and receive distribution of his remaining interest;
provided, however, that a Participant may designate a person or persons other
than his spouse as his Beneficiary if the requirements of Section 11.3 are met.

            11.2 BENEFICIARY IN THE ABSENCE OF DESIGNATED BENEFICIARY. If a
Participant or former Participant who dies does not have a surviving spouse and
if no Beneficiary has been designated pursuant to the provisions of Section
11.1, or if no Beneficiary survives such Participant or former Participant, then
the Beneficiary shall be the estate of such Participant or former Participant.
If any Beneficiary designated pursuant to Section 11.1 dies after becoming
entitled to receive distribution hereunder and before such distributions are
made in full, and if no other person or persons have been designated to receive
the balance of such distributions upon the happening of such contingency, the
estate of such deceased Beneficiary shall become the Beneficiary as to such
balance.

            11.3 SPOUSAL CONSENT TO BENEFICIARY DESIGNATION. In the event a
Participant or former Participant is married, any Beneficiary designation, other
than a designation of his spouse as Beneficiary, shall be effective only if his
spouse consents in writing thereto and such consent acknowledges the effect of
such action and is witnessed by a notary public or a Plan representative, unless
a Plan representative finds that such consent cannot be obtained because the
spouse cannot be located or because of other circumstances set forth in Section
401(a)(11) of the Code and regulations issued thereunder.

            12.1 AUTHORITY OF THE COMPANY. The Company shall have the authority
and the power to perform the functions conferred upon it herein, subject to the
limitations hereinafter set forth. The Company shall have the sole right to
interpret and construe the Plan, to determine any disputes arising thereunder,

Company and the Trustee are hereby designated as "named fiduciaries" of the Plan
as such term is defined in Section 402(a)(2) of ERISA. The Company, by action of
its Board of Directors, may designate a person other than itself to carry out
any of such powers, authorities or responsibilities.

            12.2 ACTIONS OF THE COMPANY. Any act authorized, permitted, or
required to be taken by the Company under the Plan, which has not been delegated
in accordance with Section 12.1, may be taken by a majority of the members of
the Board of Directors of the Company, either by vote at a meeting, or in
writing without a meeting. All notices, advices, directions, certifications,
approvals, and instructions required or authorized to be given by the Company
under the Plan shall be in writing and signed by either (i) a majority of the
members of the Board of Directors of the Company, or by such member or members
as may be designated by an instrument in writing, signed by all the members
thereof, as having authority to execute such documents on its behalf, or (ii) a
person who becomes authorized to act for the Company in accordance with the
provisions of Section 12.1. Subject to the provisions of Section 12.3, any
action taken by the Company which is authorized, permitted, or required under

dealing with the Company or the Trustee.

            12.3 CLAIMS REVIEW PROCEDURE. Whenever the Company decides for
whatever reason to deny, whether in whole or in part, a claim for benefits filed
by any person (hereinafter referred to as the "Claimant"), the Plan
Administrator shall transmit to the Claimant a written notice of the Company's
decision, which shall be written in a manner calculated to be understood by the
Claimant and contain a statement of the specific reasons for the denial of the
claim and a statement advising the Claimant that, within 60 days of the date on
which he receives such notice, he may obtain review of the decision of the
Company in accordance with the procedures hereinafter set forth. Within such
60-day period, the Claimant or his authorized representative may request that
the claim denial be reviewed by filing with the Plan Administrator a written
request therefor, which request shall contain the following information:

                           (a) the date on which the Claimant's request was
            filed with the Plan Administrator; provided, however, that the date
            on which the Claimant's request for review was in fact filed with
            the Plan Administrator shall control in the event that the date of
            the actual filing is later than the date stated by the Claimant
            pursuant to this paragraph (a);

                           (b) the specific portions of the denial of his claim
            which the Claimant requests the Plan Administrator to review;

                           (c) a statement by the Claimant setting forth the
            basis upon which he believes the Plan Administrator should reverse
            the Trustee's previous denial of his claim for benefits and accept
            his claim as made; and

                           (d) any written material (offered as exhibits) which
            the Claimant desires the Plan Administrator to examine in its
            consideration of his position as stated pursuant to paragraph (c).

Within 60 days of the date determined pursuant to paragraph (a) of this Section
12.3, the Plan Administrator shall conduct a full and fair review of the
Company's decision denying the Claimant's claim for benefits. Within 60 days of
the date of such hearing, the Plan Administrator shall render its written
decision on review, written in a manner calculated to be understood by the
Claimant, specifying the reasons and Plan provisions upon which its decision was
based.

            12.4 INDEMNIFICATION. In addition to whatever rights of
indemnification the members of the Board of Directors of the Company, or any
other person or persons to whom any power, authority, or responsibility of the
Company is delegated pursuant to Section 12.1, may be entitled under the
articles of incorporation, regulations, or by-laws of the Company, under any
provision of law, or under any other agreement, the Company shall satisfy any
liability actually and reasonably incurred by any such person or persons,
including expenses, attorneys' fees, judgments, fines, and amounts paid in
settlement, in connection with any threatened, pending, or completed action,
suit, or proceeding which is related to the exercise or failure to exercise by
such person or persons of any of the powers, authority, responsibilities, or
discretion provided under the Plan, or reasonably believed by such person or
persons to be provided hereunder, and any action taken by such person or persons
in connection therewith.

            12.5 QUALIFIED DOMESTIC RELATIONS ORDERS. The Company shall
establish reasonable procedures to determine the status of domestic relations
orders and to administer distributions under domestic relations orders which are
deemed to be qualified orders. Such procedures shall be in writing and shall
comply with the provisions of Section 414(p) of the Code and regulations issued
thereunder.

            12.6 VOTING OF OMG STOCK. Each Participant or Beneficiary who has
shares of OMG Stock allocated to an Account maintained with respect to a Fund
invested primarily in OMG Stock, shall be a named fiduciary with respect to the
voting of such OMG Stock and shall have the following powers and
responsibilities:
                           (a) Prior to each meeting of the shareholders of the
            Company, the Company shall cause to be sent to each such Participant
            and Beneficiary who has OMG Stock allocated to such an Account a
            copy of the proxy solicitation material therefor, together with a
            form requesting voting instructions, with respect to the voting of
            such OMG Stock as well as the voting of OMG Stock for which the
            Trustee does not receive instructions. Each such Participant and/or
            Beneficiary shall instruct the Trustee to vote the number of such
            uninstructed shares of OMG Stock equal to the proportion that the
            number of shares of OMG Stock allocated to his Account bears to the
            total number of shares of OMG Stock for which instructions are
            received. Upon receipt of such a Participant's or Beneficiary's
            instructions, the Trustee shall then vote in person, or by

                                       49
<PAGE>

            proxy, such shares of OMG Stock as so instructed. Such instructions
            shall be held in strictest confidence.

                     (b) The Company shall cause the Trustee to furnish to each
            such Participant and Beneficiary who has OMG Stock allocated to his
            Account notice of any tender or exchange offer for, or a request or
            invitation for tenders or exchanges of, OMG Stock made to the
            Trustee. The Trustee shall request from each such Participant and
            Beneficiary instructions as to the tendering or exchanging of OMG
            Stock allocated to his Account and the tendering or exchanging of
            OMG Stock for which the Trustee does not receive instructions. Each
            such Participant shall instruct the Trustee with respect to the
            tendering or exchanging of the number of such uninstructed shares of
            OMG Stock equal to the proportion that the number of the shares of
            OMG Stock allocated to his Account bears to the total number of
            shares of OMG Stock for which instructions are received. The Trustee
            shall provide such Participant and Beneficiaries with a reasonable
            period of time in which they may consider any such tender or
            exchange offer for, or request or invitation for tenders or
            exchanges of, OMG Stock made to the Trustee. Within the time
            specified by the Trustee, the Trustee shall tender or exchange such
            OMG Stock as to which the Trustee has received instructions to
            tender or exchange from Participants and Beneficiaries. Such
            instructions shall be held in strictest confidence.

                            AMENDMENT AND TERMINATION
                            -------------------------

            13.1 AMENDMENT. Subject to the provisions of Section 13.2, the
Company may at any time and from time to time, amend the Plan by resolution or
written action of its Board of Directors or by action of a committee to which
such authority has been delegated by the Board of Directors. Any such amendment
of the Plan shall be in writing and signed by individuals authorized by the
Board of Directors or its delegates.

            13.2 LIMITATION OF AMENDMENT. The Company shall make no amendment to
the Plan which shall result in the forfeiture or reduction of the interest of
any Participant or person claiming under or through any one or more of them
pursuant to the Plan; provided, however, that nothing herein contained shall
restrict the right to amend the provisions hereof relating to the administration
of the Plan and Trust. Moreover, no amendment shall be made hereunder which
shall permit any part of the Trust property to revert to any Employer or be used
for or be diverted to purposes other than the exclusive benefit of Participants
and persons claiming under or through them pursuant to the Plan.

            13.3 TERMINATION. The Company reserves the right, by action of its
Board of Directors, to terminate the Plan as to all Employers at any time, which
termination shall become effective upon notice in writing to the Trustee (the
effective date of such termination being hereinafter referred to as the
"termination date"). The Plan shall terminate automatically if there shall be a
complete discontinuance of contributions hereunder by all Employers. In the
event of the termination of the Plan, written notice thereof shall be given to
all Participants and Beneficiaries having an interest under the Plan, and to the
Trustee. Upon any such termination of the Plan, the Trustee and the Company
shall take the following actions for the benefit of Participants, and
Beneficiaries:
                     (a) As of the termination date, the Trustee shall value the
            Funds hereunder and the Company shall adjust all accounts in the
            manner provided in Section 8.1. The termination date shall become a
            Valuation Date for

                                       51
<PAGE>

            purposes of Article VIII. In determining the net worth of the Funds
            hereunder, the Trustee shall include as a liability such amounts as
            in its judgment shall be necessary to pay all expenses in connection
            with the termination of the Trust and the liquidation and
            distribution of the Trust property, as well as other expenses,
            whether or not accrued, and shall include as an asset all accrued
            income.

                     (b) The Trustee, upon instructions from the Company, shall
            then segregate and, subject to applicable provisions of the Code
            relating to the distribution of Tax Deferred Contributions,
            distribute an amount equal to the entire interest of each
            Participant in the Funds to or for the benefit of each Participant
            or Beneficiary in accordance with the provisions of Section 10.4.

Notwithstanding anything to the contrary contained in the Plan, upon any such
Plan termination, the interest of each Participant and Beneficiary shall become
fully vested and nonforfeitable; and, if there is a partial termination of the
Plan, the interest of each Participant and Beneficiary who is affected by such
partial termination shall become fully vested and nonforfeitable.

            13.4 WITHDRAWAL OF AN EMPLOYER. An Employer other than the Company
may, by action of its Board of Directors, withdraw from the Plan, such
withdrawal to be effective upon notice in writing to the Company (the effective
date of such withdrawal being hereinafter referred to as the "withdrawal date"),
and shall thereupon cease to be an Employer for all purposes of the Plan. An
Employer shall be deemed automatically to withdraw from the Plan in the event of
its complete discontinuance of contributions, or (subject to Section 13.5) in
the event it ceases to be a Subsidiary.

            13.5 EFFECT OF PLAN TERMINATION. Notwithstanding any other provision
of the Plan to the contrary, any termination of the Plan shall terminate the
liability of an Employer to make further Employer Contributions hereunder.

            13.6 CORPORATE REORGANIZATION. The merger, consolidation, or
liquidation of the Company or any Employer with or into the Company or any other
Employer shall not constitute a termination of the Plan as to the Company or
such Employer.

                                    OMG ESOP
                                    --------

            14.1 PURPOSE. The OMG ESOP, which is incorporated as part of the
Plan, is intended to be an employee stock ownership plan under Section
4975(e)(7) of the Code and Section 407(a)(6) of the ERISA. The purposes of the
OMG ESOP are to invest primarily in qualifying employer securities as defined in
Section 409(l) of the Code, to enable Participants to share in the growth and
prosperity of the Company and to provide such Participants with an additional
opportunity to accumulate capital for their future economic security.

            14.2 SUSPENSE FUND. The Trustee shall establish a subfund, herein
referred to as the Suspense Fund, to hold and administer any OMG Stock which
could be pledged as collateral for any Exempt Loan made to the Trustee for
purposes of the OMG ESOP. In the event more than one class of OMG Stock is held
in the Suspense Fund, any release thereof shall be made on a pro-rata basis as
shall allocations thereof to the Separate Accounts of Participants.

            14.3 EXEMPT LOANS. The Trustee may finance or re-finance the
acquisition of OMG Stock for purposes of the OMG ESOP through Exempt Loans. An
installment obligation incurred in connection with the purchase of OMG Stock
shall constitute an Exempt Loan and shall be for a specific term, bear a
reasonable rate of interest, and shall not be payable on demand except in the
event of default. An Exempt Loan may be secured by a collateral pledge of the
shares of OMG Stock so acquired. Any such pledged OMG Stock shall be placed in
the Suspense Fund. No other Plan assets may be pledged as collateral for a Loan,
and no lender shall have recourse against the Plan other than the OMG Stock
subject to pledge. All Exempt Loans which are made or guaranteed by a
disqualified person must satisfy all requirements applicable to exempt loans set
forth in Treas. Reg. Section 54.4975-7(b)(8) and Department of Labor Reg.
Section 2550.408b-3. Any pledge of OMG Stock must provide for the release of
shares so pledged on a pro rata basis as the Exempt Loan is repaid by the
Trustee and such shares of OMG Stock are allocated to Separate Accounts of
Participants as provided in the Plan. Repayments of principal and interest on
any

                                       53
<PAGE>

Exempt Loan shall be made by the Trustee from the contributions designated to be
invested in OMG Stock Fund to enable the Trustee to repay such Exempt Loan, from
earnings attributable to such contributions, and from any cash dividends
received by the Trustee on OMG Stock held in the Suspense Fund.

            14.4 LIMITATION ON ALLOCATIONS OF CONTRIBUTIONS. Notwithstanding any
other provision of the Plan to the contrary, OMG Stock held in the Suspense Fund
shall be allocated to the Accounts of Participants only as payments of principal
and interest on an Exempt Loan are made by the Trustee. OMG Stock which is
released from the Suspense Fund shall be allocated to the Account and
subaccounts thereunder of each eligible Participant as needed to provide Company
Contributions pursuant to Section 4.1 as well as Tax Deferred Contributions
pursuant to Section 4.2, Participant Contributions pursuant to Section 4.3,
Rollover Contributions pursuant to Section 4.7, and Transferred Contributions
pursuant to Section 4.8, which have been designated to invest in the OMG Stock
Fund. The number of shares of OMG Stock to be released from the Suspense Fund
for allocation a Participant's Account shall be calculated in accordance with
Treas. Reg. Section 54.4975-7(b)(8). Principal and interest payable under an
Exempt Loan shall be satisfied out of (i) Company Contributions (other than
contributions of OMG Stock) that are made hereunder for purposes of being
applied by the Trustee to satisfy its obligations under the Exempt Loan; (ii)
earnings attributable to the investment of such contributions; and (iii)
earnings attributable to OMG Stock purchased with the proceeds of the Exempt
Loan; provided, however, that the payments made under the Exempt Loan by the
Trustee during any Plan Year shall not exceed an amount equal to the sum of such
contributions and earnings received during the Plan Year and prior Plan Years
minus payments made under the Exempt Loan in such Plan Years. Contributions and
earnings that may be used by the Trustee to make payments under the Exempt Loan
shall be accounted for separately in the books and records of the Trustee until
the Exempt Loan is repaid in full. Notwithstanding any provision contained
herein to the contrary, all Company contributions (except contributions of OMG
Stock) made hereunder and Tax Deferred Contributions, Participant Contributions,
Rollover Contributions and Transferred Contributions

                                       54
<PAGE>

designated to be invested in the OMG Stock Fund during the term of an Exempt
Loan shall be deemed to be made for purposes of being used by the Trustee to
satisfy its obligations under the Exempt Loan. Furthermore, all payments made by
the Trustee under the Exempt Loan shall be first charged against Company
Contributions available for making such payments, then to Tax Deferred
Contributions, then Participant Contributions, then Rollover Contributions and
then Transferred Contributions. Earnings that may be used to make payments under
the Exempt Loan shall be deemed to have been used for that purpose only to the
extent that payments made under the Exempt Loan during any Plan Year are in
excess of the total contributions available to the Trustee for making payments
under the Exempt Loan. Contributions which are not utilized by the Trustee to
pay principal and interest of an Exempt Loan shall be allocated to the Accounts
of eligible Participants and invested in the OMG Stock Fund.

            14.5 ALLOCATIONS OF CONTRIBUTIONS FROM THE OMG ESOP. Contributions
allocated and credited to each Participant's Accounts in the form of OMG Stock
that is released from the Suspense Fund shall be allocated to such Participant's
Accounts by multiplying the number of shares of OMG Stock so released for any
month by a fraction the numerator of which is the Participant's share of
contributions to be invested in the OMG Stock Fund and the denominator for such
month and the denominator of which is the aggregate of all Participants'
contributions to be invested in the OMG Stock Fund. In the event the amount of
contributions to be invested in the OMG Stock Fund for any month exceeds the
amount distributable to released shares, such excess contributions shall be used
to purchase OMG Stock in the market. Such OMG Stock shall then be allocated to
Participants' Accounts by multiplying the number of shares of OMG Stock so
purchased for any month by a fraction the numerator of which is the
Participant's contributions allocated to his Accounts to be invested in the OMG
Stock Fund for such month and the denominator of which is the aggregate of all
Participants' contributions to be invested in the OMG Stock Fund for such month.
In the event the dividends on OMG Stock held in Participants' Accounts are used
to make payments of principal and/or interest on an Exempt Loan pursuant to

                                       55
<PAGE>

the provisions of Section 14.3, OMG Stock released from the Suspense Fund as a
result thereof shall be allocated to such Participants' Accounts in such a
manner that the aggregate fair market value of the OMG Stock so allocated is not
less than the amount of the dividends that would have otherwise been allocated
to such Accounts.

            14.6 DIVIDENDS ON OMG STOCK. Except as specified in the Trust
Agreement, cash dividends received with respect to the shares of OMG Stock
acquired with the proceeds of an Exempt Loan and held in the Suspense Fund shall
be applied to the payment of principal and/or interest on any outstanding Exempt
Loan and any other dividends received with respect to any other shares of OMG
Stock held in the OMG ESOP shall be applied, invested, or distributed in
accordance with the directions of the Company, including the payment thereof to
Participants either currently or in periodic payments.

            14.7 RESTRICTIONS ON OMG STOCK. No OMG Stock shall be subject to a
put, call, or other option, or any buy-sell arrangement while held by and when
distributed from the OMG ESOP, whether or not such plan is an employee stock
ownership plan at such time.

                            MISCELLANEOUS PROVISIONS
                            ------------------------

            15.1 EXTENSION OF PLAN TO SUBSIDIARIES. Any Related Corporation
which at the time is not an Employer may, with the consent of the Board of
Directors of the Company, adopt the Plan and become an Employer hereunder by
causing an appropriate written instrument evidencing such adoption to be
executed pursuant to the authority of its Board of Directors and to be filed
with the Company.

            15.2 NO COMMITMENT AS TO EMPLOYMENT. Nothing herein contained shall
be construed as a commitment or agreement upon the part of any Employee
hereunder to continue his employment with an Employer, and nothing herein
contained shall be construed as a commitment on the part of any Employer to
continue the employment or rate of compensation of any Employee hereunder for
any period.

            15.3 BENEFITS. Nothing in the Plan shall be construed to confer any
right or claim upon any person other than the parties hereto, Participants and
Beneficiaries.

            15.4 NO GUARANTEES. Neither any Employer, including the Company, nor
the Trustee guarantees the Trust from loss or depreciation, nor the payment of
any amount which may become due to any person hereunder.

            15.5 PRECEDENT. Except as otherwise specifically provided, no action
taken in accordance with the terms of the Plan, by an Employer or the Company
shall be construed or relied upon as a precedent for similar action under
similar circumstances.

            15.6 DUTY TO FURNISH INFORMATION. Each of the Employers, the
Company, or the Trustee shall furnish to any of the others any documents,
reports, returns, statements, or other information that any other reasonably
deems necessary to perform its duties imposed hereunder or otherwise imposed by
law.

            15.7 MERGER, CONSOLIDATION OR TRANSFER OF PLAN ASSETS. The Plan
shall not be merged or consolidated with any other plan, nor shall any of its
assets or liabilities be transferred to another

                                       57

plan, unless, immediately after such merger, consolidation, or transfer of
assets or liabilities, each Participant in the Plan would receive a benefit
under the Plan which is at least equal to the benefit he would have received
immediately prior to such merger, consolidation, or transfer of assets or
liabilities (assuming in each instance that the Plan had then terminated).

            15.8 INTERNAL REVENUE SERVICE DETERMINATION. Notwithstanding any
other provision of the Plan to the contrary, each contribution of the Employer
made to the Trust Fund is conditioned upon the requirement that the amount of
the contribution shall be deductible under Section 404 of the Code. In the event
that any contribution, or portion thereof, is disallowed such contribution or
portion shall be returned by the Trustee to the Employer, if demand therefor is
made by the Employer within one year of the date of such disallowance.

            15.9 GOVERNING LAW. The Plan shall be construed and interpreted in
accordance with the laws of the State of Ohio.

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

               A.1 COMPLIANCE WITH TRA `86. The provisions set forth in this
Appendix A are intended solely to comply with the requirements of Section 415 of
the Code, as amended by the Tax Reform Act of 1986, and shall be interpreted,

Section, subject, however, to the provisions of Section 1106(i)(3) of the Tax
Reform Act of 1986. For such purpose, the limitations of Section 415 of the
Code, as amended by the Tax Reform Act of 1986, are hereby incorporated by
reference and made part hereof as though fully set forth herein, but shall be
applied only to particular Plan benefits in accordance with the provisions of
this Appendix A to the extent such provisions are not consistent with said
Section.

               A.2 SECTION 415 DEFINITIONS. For purpose of this Appendix A the

                     such Limitation Year;

                           (ii) For Limitation Years prior to January 1, 1987,
                     the lesser of (A) the amount of such Participant's
                     contributions, but only to the extent that the sum of such
                     Contributions exceeds six percent of his Compensation paid
                     for such Limitation Year, or (B) one-half of the
                     Participant's contributions, if any; and for Limitation
                     Years on and after January 1, 1987, all contributions made
                     by a Participant to the Plan for such Limitation Year;

                           (iii) The amount, if any, of Employer contributions
                     and forfeitures which are credited to the Participant under
                     any other defined contribution plan (whether or not
                     terminated) maintained by an Employer or a Related
                     Corporation concurrently with the Plan;

<PAGE>

                           (iv)     Reallocated forfeitures;

                           (v) Contributions to an individual medical account as

                     which are attributable to post-retirement medical benefits
                     allocated to a separate account of a key employee (as
                     defined in Appendix B of the Plan) under a welfare benefit
                     fund (as defined in Section 419(e) of the Code) maintained

               actually rendered in the course of employment with an Employer or
               a Related Corporation, excluding, however, (i) contributions made
               by an Employer or a Related Corporation to a plan of deferred
               compensation to the extent that, before the application of the
               limitations of Section 415 of the Code to such plan, the
               contributions are not includable in the gross income of the
               Participant for the taxable year in which contributed, (ii)
               contributions made by an Employer or a Related Corporation on his
               behalf to a simplified employee pension plan described in Section
               408(k) of the Code, (iii) any distributions from a plan of
               deferred compensation (other than amounts received pursuant to an
               unfunded non-qualified plan in the year such amounts are
               includable in the gross income of the Participant), (iv) amounts
               received from the exercise of a non-qualified stock option or
               when restricted stock or other property held by the Participant
               becomes freely transferable or is no longer subject to
               substantial risk of forfeiture, (v) amounts received from the

               special tax benefits, such as premiums for group term life
               insurance (but only to the extent that the premiums are not
               includable in gross income of the Participant).

                     (d) The term "LIMITATION YEAR" shall mean the 12-month
               period commencing each January 1 and ending each subsequent
               December 31 or such other 12-month period elected by the Employer
               pursuant to regulations under Section 415 of the Code.

               A.3 MAXIMUM ANNUAL ADDITIONS. For each Limitation Year, the
Annual Additions with respect to a Participant shall not exceed the lesser of
(i) $30,000 (except such amount shall be adjusted in accordance with regulations
prescribed by the Secretary of the

                                       A-2

<PAGE>

Treasury for increases in the cost of living), or (ii) 25 percent of such
Participant's Compensation paid for such Limitation Year. If a short Limitation
Year is created because of an amendment changing the Limitation Year to a
different 12-month consecutive period, such Annual Additions shall not exceed
$30,000 multiplied by a fraction, the numerator of which is the number of months
in the short Limitation year, and the denominator of which is 12.

         A.4 ELIMINATION OF EXCESS CONTRIBUTIONS. If the Annual Additions to the
accounts of a Participant in any Limitation Year would exceed the limitation
contained in this Appendix A absent such limitation, the excess shall be
eliminated as follows:

                     (a) The Participant Contributions credited to the
               Separate Accounts of such a Participant for such Limitation
               Year shall be reduced and returned to the Participant;

                     (b) Next, Tax Deferred Contributions credited to the
               Separate Accounts of such Participant for such Limitation Year
               shall be returned to the Participant unless the Participant has
               elected to have them transferred and deposited under a deferred
               compensation program or an excess benefit plan maintained by the
               Company; and

                     (c) The Company Contributions credited to the Separate
               Accounts of such Participant for such Limitation Year shall be
               reduced and returned to the Employers.

               In each case specified above, the amount to be reduced, returned,
               or transferred shall be that amount as is necessary to permit the
               maximum amount of the Annual Additions to the Participant's
               Accounts for such year to be made under the Plan without
               violating the restrictions of Section 415 of the Code.
               Notwithstanding the foregoing, in the event that the limitations
               with respect to Annual Additions prescribed hereunder are
               exceeded with respect to any Participant and such excess arises
               as a consequence of the allocations of forfeitures or a
               reasonable error in estimating the Participant's annual
               Compensation, the portion of such excess attributable to Company
               Contributions shall be held in a suspense account and, if such
               Participant remains a Participant, shall be used to reduce
               Company Contributions for such Participant for the succeeding
               calendar years, and, if such Participant ceases participating in
               the Plan, shall be used to reduce Company Contributions for all
               other Participants in the calendar year in which he ceases to be
               a Participant and succeeding calendar years, as necessary.

               A.5 DEFINED BENEFIT PLAN COVERAGE. If any Participant in the Plan
also shall be covered by a qualified defined benefit plan (whether or not
terminated) maintained by an Employer or by a Related Corporation concurrently
with the Plan, the sum of the defined benefit plan fraction with respect to such
Participant and the defined contribution plan fraction with respect to such
Participant for any Limitation Year ending on or before December 31, 1982, shall
not exceed 1.4, and for any Limitation Year after December 31, 1982, shall not
exceed 1.0. For purposes of this Section A.5, defined benefit plan fraction and
defined contribution plan fraction shall mean the following:

                     (i)   Defined benefit plan fraction shall mean a fraction,
                           the numerator of which is the projected annual
                           benefit of such Participant under all such plans
                           (determined as of the close of such Limitation Year)
                           and the denominator of which is the lesser of (i) the
                           product of 1.25 (1.0 prior to 1983) multiplied by the
                           dollar limitation in effect under Section
                           415(b)(1)(A) of the Code for such year or (ii) the
                           product of 1.4 (1.0 prior to 1983) multiplied by the
                           amount which may be taken into account under Section
                           415(b)(1)(B) of the Code with respect to such
                           Participant for such year; provided, however, that
                           (A) if a Participant was a participant prior to
                           January 1, 1983, and on December 31, 1982, his
                           accrued benefit exceeded the maximum defined benefit
                           dollar limitation on January 1, 1983, or (B) if a
                           Participant was a participant prior to January 1,
                           1987, and his accrued benefit on December 31, 1986
                           exceed the maximum defined benefit dollar limitation
                           on January 1, 1987, then such limitation with respect
                           to such Participant shall be equal to the greater of
                           his accrued benefits as of December 31, 1982 or
                           December 31, 1986, as the case may be.

                     (ii)  Defined contribution plan fraction shall mean a
                           fraction, the numerator of which is the sum of the
                           aggregate Annual Additions of the Participant under
                           the Plan and any other defined contribution plan as
                           of the close of the Limitation Year and the
                           denominator of which is the sum of the lesser of the
                           following amounts determined for such year and each
                           prior year of service with an Employer or a Related
                           Corporation: (i) the product of 1.25 (1.0 prior to
                           1983) multiplied by the dollar limitation in effect
                           under Section 415(c)(1)(A) of the Code for such year,
                           determined without regard to Section 415(c)(6) of the
                           Code, or (ii) the product of 1.4 (1.0 prior to 1983)
                           multiplied by

                                       A-4

<PAGE>

                           the amount which may be taken into account under
                           Section 415(c)(1)(B) of the Code with respect to such
                           Participant for such year; provided, however, that
                           the denominator may be determined under any
                           transitional rules for years ending prior to January
                           1, 1983, prescribed by the Code (including the
                           special transitional rule set forth in Section
                           415(e)(6) of the Code, if the Plan Administrator so
                           elects).

In the event the special limitation contained in this Section A.5 is exceeded,
the benefits otherwise payable to the Participant under any such qualified
defined benefit plan shall be reduced to the extent necessary to meet such
limitation.

               A.6   AGGREGATION OF DEFINED CONTRIBUTION PLANS. In the event
that a Participant is covered by any other qualified defined contribution plan
(whether or not terminated) maintained by an Employer or a Related Corporation
concurrently with the Plan, then the total Annual Additions to the Participant's
accounts under all such plans shall not exceed the limitation set forth in
Section A.3. For purposes of this Section A.6, Annual Additions under the Plan
shall be deemed to have been made or provided after Annual Additions to all
other defined contribution plans subject to the limitations set forth in Section
A.3; thus contributions under the Plan shall be affected by the limitations
before contributions under all other defined contribution plans are affected.

                                   APPENDIX B

                              TOP-HEAVY PROVISIONS
                              --------------------

               B.1   APPLICABILITY. Notwithstanding any other provision to the
contrary, in the event the Plan is deemed to be a top-heavy plan for any Plan
year, the provisions contained in this Appendix B with respect to Company
Contributions shall be applicable with respect to such Plan Year. In the event
that the Plan is determined to be a top-heavy plan and upon a subsequent
determination date is determined to no longer be a top-heavy plan, the Company
Contribution provisions in effect immediately preceding the Plan Year in which
the Plan was determined to be a top-heavy plan shall again become applicable as
of such subsequent determination date.

               B.2   TOP-HEAVY DEFINITIONS.  For purposes of this Appendix B,
the following definitions shall apply:

                           (a) The term "DETERMINATION DATE" with respect to any
                  Plan Year shall mean the last day of the preceding Plan Year
                  (or, in the case of the first Plan Year of the Plan, the last
                  day of the first Plan Year). Distributions made and the
                  present value of accrued benefits are determined as of the
                  determination date. The present value of an accrued benefit
                  under a defined contribution plan as of a determination date
                  shall be the sum of (i) the account balance as of the most
                  recent valuation date occurring within a 12-month period
                  ending on the determination date, and (ii) an adjustment for
                  contributions due as the determination date. The present value
                  of an accrued benefit under a defined benefit plan as of a
                  determination date shall be determined as of the most recent
                  valuation date which is within the 12-month period ending on
                  the determination date. In the case of an aggregation group,
                  the present value of the accrued benefits is determined
                  separately for each plan as of each plan's determination date
                  and then aggregated by adding for such plans which fall within
                  the same calendar year.

                           (b) The term "KEY EMPLOYEE" shall mean any
                  Participant or former Participant who is a key employee
                  pursuant to the provisions of Section 416(i)(1) of the Code
                  and any Beneficiary of such Participant or former Participant.

                           (c) The term "NON-KEY EMPLOYEE" shall mean any

                                      B-1

<PAGE>

                     Participant who is not a key employee.

                           (d) The term "PERMISSIVE AGGREGATION GROUP" shall
                     mean those plans not included in an Employer's required
                     aggregation group in conjunction with any other plan or
                     plans of such Employer, so long as the entire group of
                     plans would continue to meet the requirements of Sections
                     401(a)(4) and 410 of the Code.

                           (e) The term "REQUIRED AGGREGATION GROUP" shall
                     include (i) all plans of an Employer in which a key
                     employee is a participant or has participated at any time
                     during the determination period (regardless of whether the
                     Plan has terminated) and (ii) all other plans of an
                     Employer which enable a plan described in clause (i) hereof
                     to meet the requirements of Sections 401(a)(4) or 410 of
                     the Code.

                           (f) The term "SUPER TOP-HEAVY GROUP" with respect to
                     a particular Plan Year shall mean a required or permissive
                     aggregation group that, as of the determination date, would
                     qualify as a top-heavy group under the definition in
                     paragraph (h) of this Section B.2 with "90 percent"
                     substituted for "60 percent" each place where "60 percent"
                     appears in such definition.

                           (g) The term "SUPER TOP-HEAVY PLAN" with respect to a
                     particular Plan Year shall mean a plan that, as of the
                     determination date, would qualify as a top-heavy plan under
                     the definition in paragraph (i) of this Section B.2 with
                     "90 percent" substituted for "60 percent" each place where
                     "60 percent" appears in such definition. A plan is also a
                     "super top-heavy plan" if it is part of a super top-heavy
                     group.

                           (h) The term "TOP-HEAVY GROUP" with respect to a
                     particular Plan Year shall mean a required or a permissive
                     aggregation group if the sum, as of the determination date,
                     of the present value of the cumulative accrued benefits for
                     key employees under all defined benefit plans included in
                     such group and the aggregate of the account balances of key
                     employees under all defined contribution plans included in
                     such group exceeds 60 percent of a similar sum determined
                     for all employees covered by the plans included in such

                                  (i)   If the top heavy ratio for the plan
                                        exceeds 60% and the plan is not part of
                                        any required aggregation group or
                                        permissive aggregation group of plans,

                                  (ii)  If a plan is a part of a required (but
                                        not a permissive) aggregation group of
                                        plans and the top heavy ratio or the
                                        required aggregation group of plans
                                        exceeds 60%, or

                                  (iii) If the plan is a part of a required
                                        aggregation group of plans and part of a
                                        permissive aggregation group of plans,
                                        and the top heavy ratio for the
                                        permissive aggregation group exceeds
                                        60%.

                           Notwithstanding the foregoing provisions of this
                     paragraph, however, a plan shall be deemed not to be a
                     top-heavy plan if it is part of a required or permissive
                     aggregation group that is not a top-heavy group.

                           (j) The term "COMPENSATION" shall mean a
                     Participant's total wages and salary for services rendered
                     to the Employers less amounts realized from the exercise or
                     disposition of stock options paid by the Employers during a
                     calendar year to the extent it would be taken into account
                     for Form W-2 purposes; provided, however, that such
                     compensation shall not exceed the dollar limitation set
                     forth in Section 1.1(5) of the Plan to comply with Section
                     401(a)(17) of the Code.

                                     (i) If the Employer maintains one or more
                     defined contribution plans (including any simplified
                     employee

                                      B-3

<PAGE>

                     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 as of the
                     determination date(s) including any part of any account
                     balance distributed in the 5-year period ending on the
                     determination date(s)), and the denominator of which is the
                     sum of all account balances (including any part of any
                     account balance distributed in the 5-year period ending on
                     the determination date(s)), both computed in accordance
                     with Section 416 of the Code. Both the numerator and
                     denominator of the top-heavy ratio are adjusted 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 Section 416 of the Code.

                                     (ii) If the Employer maintains one or more
                     defined contribution plans (including any simplified
                     employee pension plans) 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 account
                     balances under the aggregated defined contribution plan or
                     plans for all key employees, determined in accordance with
                     subparagraph (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
                     subparagraph (i) above and the present value of the accrued
                     benefits under the defined benefit plan or plans for all
                     participants as of the determination date(s), all
                     determined in accordance with Section 416 of the Code. The
                     accrued benefits under a defined benefit plan is both the
                     numerator and denominator of the top-heavy ratio are
                     adjusted for any distribution of an accrued benefit made in
                     the five-year period ending on the determination date.

                                    (iii) For purposes of subparagraphs (i) and
                     (ii) above, the value of

                                      B-4
<PAGE>

                     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 Section
                     416 of the Code for the first and second plan years of a
                     defined benefit plan. The account balances and accrued
                     benefits of a participant (1) who is not a key employee
                     but who was a key employee in a prior year, or (2) who has
                     not performed services for the Employer maintaining the
                     Plan at any time during the 5-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 Section 416 of the
                     Code. Deductible employee contributions shall 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 date(s) that fall within
                     the same calendar year.

               B.3   MINIMUM EMPLOYER CONTRIBUTION. In the event the Plan is
determined to be a top-heavy plan with respect to any Plan Year, the Company
Contributions allocated with respect to such Plan Year to the Accounts of each
non-key employee who is a Participant and who is not separated from service with
an Employer as of the end of such Plan Year, regardless of whether such non-key
employee has completed less than 1,000 Hours of Service or fails to make either
mandatory employee contributions or elective contributions, shall be no less
than the lesser of (a) three percent of his compensation or (b) the largest
percentage of compensation that is allocated for such Plan Year to the Accounts
attributable to Company Contributions of any key employee, except that, in the
event the Plan is part of a required aggregation group, and the Plan enables a
defined benefit plan included in such group to meet the requirements of Section
401(a)(4) or 410 of the Code, the minimum allocation of Company Contributions to
the Accounts of each non-key employee shall be three percent of the compensation
of such non-key employees. Any minimum allocation of Company Contributions of a
Participant required by this Section B.3 shall be made without regard to any
social security contribution made by the Employer on behalf

                                      B-5
<PAGE>

of the Participant and without regard to whether or not a non-key employee
withdraws Tax Deferred Contributions. Notwithstanding the minimum top-heavy
allocation requirements of this Section B.3, in the event that the Plan is a
top-heavy plan, each non-key employee hereunder who is also covered under a
top-heavy defined benefit plan maintained by an Employer shall receive the
top-heavy benefits provided for under such defined benefit plan in lieu of the
minimum top-heavy allocation under the Plan.

               B.4 TOP-HEAVY VESTING SCHEDULE. A Participant shall be entitled
to the vested interest in his Accounts attributable to Company Contributions
calculated in accordance with the provisions of Articles III and IV (or, if
greater, in accordance with the provisions of Section B.3 above) determined in
accordance with the following schedule:

                Years of Service   Vested Percentage
                ----------------   -----------------

               2 but less than 3                     20%
               3 but less than 4                     40%
               4 but less than 5                     60%
               5 but less than 6                     80%
               6 or more                            100%

If the Plan becomes Top-Heavy and subsequently ceases to be such, the vesting
schedule set for the above shall continue to apply in determining the rights to
benefits of any Participant who had at least five Years of Service as of
December 31 in the last Plan Year in which the Plan was Top-Heavy. For other
Participants, such schedule shall apply only to that portion of their Accounts
that became vested under the vesting schedule set forth above as of such
December 31.

               B.5   ADJUSTMENTS TO SECTION 415 LIMITATIONS. Notwithstanding the
provisions of Section A.5, in the event that the Plan is a top-heavy plan and an
Employer maintains a defined benefit plan covering some or all of the employees
that are covered by the Plan, Section 415(e)(2)(B) and 415(e)(3)(B) of the Code
shall be applied to the Plan by substituting "1.0" for "1.25" and Section
415(e)(6)(B)(i) of the Code shall be applied to the Plan by substituting

                                      B-6
<PAGE>

"$41,500" for $51,875", except that such substitutions shall not be applied to
the Plan if (a) the Plan is not a super top-heavy plan and (b) a Company
Contribution for such Plan Year for each non-key employee who is a Participant
is not less than four percent of such non-key employee's compensation.

               B.6 COMPENSATION TAKEN INTO ACCOUNT. The annual compensation of
any Participant to be taken into account under the Plan during any Plan Year in
which the Plan is determined to be a top-heavy plan shall not exceed $150,000
(or such adjusted amount determined by the Secretary of the Treasury.

                                     PART A

         Effective as of January 1, 1997, unless specifically provided
otherwise, the Plan is hereby amended in the following manner.

         1. Paragraph (9) of Section 1.1 of the Plan is hereby amended to
provide as follows:

                           (9) The term "COMPENSATION" shall mean the total
                  wages which are paid to an Employee during a Plan Year by an
                  Employer for his services as an Employee while he is a
                  Participant, but excluding any portion of a Company
                  Contribution which is subject to the cash option election
                  described in Section 4.2 and which a Participant elects to
                  receive in cash, any amounts received under the Company's
                  dependent scholarship program, and all non-cash remuneration;
                  provided, however, that for Plan Years beginning on or after
                  January 1, 1994, the annual Compensation of a Participant
                  taken into account under the Plan shall not exceed $150,000,
                  as adjusted for increases in the cost of living in accordance
                  with the provisions of Section 401(a)(17)(B) of the Code. The
                  cost of living in effect for a calendar year applies to any
                  period, not exceeding 12 months, over which Compensation is
                  determined (a "determination period") beginning in such
                  calendar year. If a determination period consists of fewer
                  than 12 months, the annual compensation limit will be
                  multiplied by a fraction, the numerator of which is the number
                  of months in the determination period and the denominator of
                  which is 12.

         2. Paragraph (20) of Section 1.1 of the Plan is hereby amended to
provide as follows:

                                            "safe harbor plan" is a plan that
                                            satisfies the requirements of
                                            Section 414(n)(5) of the Code which
                                            generally will be a money purchase
                                            pension plan with a nonintegrated
                                            employer contribution rate of at
                                            least 10% of compensation and which
                                            provides for immediate participation
                                            and full and immediate vesting).

                  A person who is a Leased Worker shall be considered an
                  employee of the Company or a Related Corporation solely for
                  the purpose of determining length of service for (i)
                  eligibility for participation, and (ii) vesting purposes, but
                  shall not be a Participant and shall not otherwise be eligible
                  to become covered by the Plan during any period in which he is
                  a Leased Worker. Notwithstanding the foregoing, the sole
                  purpose of this paragraph (20) is to define and apply the term
                  "leased employees." This paragraph (20) shall be interpreted,
                  applied and, if and to the extent necessary, deemed modified

                  the minimum requirements of Section 414(n) of the Code.

                  Participant's Compensation shall be 100% vested in such
                  Participant.

         4. Section 10.4 of the Plan is hereby amended to provide as follows:

                           10.4 DISTRIBUTION. Except as otherwise set forth
                  below with respect to certain Accounts, the Company shall
                  direct the Trustee to make distribution to or for the benefit
                  of a Participant, who incurs a Settlement Date pursuant to the
                  provisions of Section 10.1, from his interest under the Plan
                  which, on any date, shall be equal to the balance of his
                  Accounts as of such date. Such distribution shall be made in a
                  single lump-sum payment or installments payment payable to
                  such Participant at such time and manner as set forth in
                  procedures adopted by the Company. In the event such
                  Participant fails to consent to distribution of his Accounts,
                  such failure shall be deemed to be an election to defer the
                  payment of any benefits sufficient to satisfy this Section
                  10.4 and payment of his benefit shall not occur until the
                  earlier of the receipt of his application for distribution or
                  his Mandatory Distribution Date. Notwithstanding the
                  foregoing, if at the time benefits are distributable under the
                  preceding sentence, the balance credited to a Participant's
                  Accounts exceed $3,500 (or such higher amount permitted under
                  Section 417(e) of the Code), benefits shall be paid only if
                  the Participant consents in writing to such distribution not
                  more than 90 days before commencement of distribution.

         5. Section 10.12 of the Plan is hereby amended to provide as follows:

                           10.12 MANDATORY DISTRIBUTIONS. Notwithstanding any
                  other provision of this Article X, in the event the vested
                  aggregate balance of a Participant's Accounts which are
                  distributable to him do not exceed $3,500 (or such higher
                  amount permitted under Section 417(e) of the Code), such
                  balance shall be distributed to him in a single sum as soon as
                  practicable after the Settlement Date. If, however, the vested
                  aggregate balance of a Participant's Accounts exceeds, or at
                  the time of any prior distribution exceeded, $3,500 (or such
                  higher amount permitted under Section 417(e) of the Code), no
                  distribution of such balance shall be made to him, unless such
                  Participant consents in writing to such distribution;
                  provided, however, that, in no event shall the distribution of
                  the interest of a Participant commence later than such a
                  Participant's Mandatory Distribution Date and shall be
                  determined and made in accordance with the proposed
                  regulations under Section 401(a)(9) of the Code, including the
                  minimum distribution incidental benefit requirements of
                  Section 1.401(a)(9)-2 of the proposed regulations.
                  Accordingly, the entire interest of a Participant in his
                  Accounts must be distributed or must begin to be distributed
                  no later than the Participant's Mandatory Distribution Date. A
                  Participant's Mandatory Distribution Date shall be the date
                  determined under paragraph (a) or the date determined under
                  paragraph (b), whichever is earlier:

                                    (a) unless the Participant elects otherwise,
                           the 60th day

                           the following dates occurs: (i) the Participant's
                           attainment of age 65, (ii) the tenth anniversary of
                           the date on which the Participant first became a
                           Participant, or (iii) the date of the Participant's
                           retirement or other termination of employment; or

                                    (b) the April 1 following the calendar year
                           in which the later of the following dates occurs: (i)
                           the date on which the Participant attains age 70-1/2,
                           or (ii) the date on which the Participant retires
                           (except for a Participant who is a 5% owner, as
                           defined in Section 416(i)(1)(B)(i) of the Code, the
                           date determined under this paragraph (b) shall be
                           April 1 of the calendar year following the calendar
                           year in which the Participant attains age 70-1/2,
                           without regard to the date of the Participant's
                           retirement).

                           In the event that a 5% owner has not terminated
                           employment as of his Mandatory Distribution Date, he
                           shall receive distribution of his Accounts pursuant
                           to the provisions of this Section 10.12 in effect
                           prior to January 1, 1997. In the event that any
                           Participant who is employed by the Company or a
                           Related Corporation on January 1, 1997, has begun to

                           1997, such Participant may elect in writing in the
                           manner and form required by the Company to have such
                           distributions that become payable after January 1,
                           1997 terminate until his Accounts become payable
                           after his retirement in accordance with the terms of
                           the Plan in effect at such time. In the event that
                           such a Participant does not make such an election,
                           distribution of his Accounts shall continue to be
                           made to him pursuant to the provisions of this
                           Section 10.12 in effect prior to January 1, 1997.
                           Notwithstanding the foregoing, any Participant who
                           attains age 70-1/2 in 1996, 1997, or 1998 may elect
                           in writing in the manner and form required by the
                           Company to defer payments from his Accounts until
                           after his termination of employment in accordance
                           with the terms of the Plan in effect at such time. If
                           such Participant does not make such an election or if
                           such Participant is a 5% owner, payments from his
                           Accounts shall be made to him pursuant to the
                           provisions of this Section 10.12 in effect prior to
                           January 1, 1997. In the event that a Participant dies
                           before the his Mandatory Distribution Date,
                           distribution of such Participant's Accounts must be
                           completed by December 31 of the calendar year
                           containing the fifth anniversary of the Participant's
                           death.

                           of Articles IV and VII.

         12. Section 3.3 of the Plan is hereby amended to provide as follows:

                           3.3 YEARS OF SERVICE. For purposes of the Plan, Years
                  of Service shall be determined in accordance with the

                                    (a) An Employee shall be credited with a
                           Year of Service for each Plan Year in which he
                           completes at least six months of Service.

                                    (b) An Employee shall be credited with

                           ending on his next following Severance Date. If an
                           Employee's Reemployment Date occurs within 12 months
                           after the earlier of (i) his immediately preceding

                           which he remains absent from employment with an
                           Employer or the Related Corporation for any reason,
                           he shall be credited with Service for the period of
                           absence preceding such Reemployment Date if he
                           otherwise is not credited with Service for such
                           absence under the foregoing provisions of this
                           Section 3.3. In the event that a Severance Date
                           occurs with respect to an Employee and the provisions
                           of the foregoing sentence of this Section 3.3 do not
                           apply, such Employee shall forfeit his Service
                           credited with respect to the period ending on such
                           Severance Date, and the Employee's Service shall be
                           reinstated upon his completion of an Hour of Service
                           as an Employee, if his period of absence is less than
                           five years or in the event it is greater than five
                           years:

                                            (i) if he had any nonforfeitable
                                    interest to any portion of his Account
                                    attributable to Company Contributions at the
                                    time of his Severance Date; or

                                            (ii) if upon returning to service
                                    his period of absence was less than his
                                    Years of Service prior to his Severance
                                    Date.

                           An Employee's Years of Service as determined under
                           this Section 3.3 shall be computed to the nearest
                           month and aggregated.

                           4.6 ALLOCATION OF COMPANY CONTRIBUTIONS. Any Company
                  Contribution made by an Employer pursuant to Section 4.1 shall
                  be allocated among Participants of such Employer who are
                  Participants as of the last day of the Plan Year for which
                  such Company Contribution is contributed and who have

                  of 10 Years of Service, became permanently and totally
                  disabled, or died during such Plan Year. Such allocation shall
                  be (a) made in the ratio which the Compensation of each such
                  Participant for such Plan Year bears to the aggregate
                  Compensation of all such designated Participants of such
                  Employer for such preceding Plan Year, minus (b) the amount,
                  if any, that the Participant elected to receive in cash

                  such time or times and in such manner as shall be specified by
                  the Company. Upon receipt by the Trustee, such assets shall be
                  deposited in the Fund or Funds selected by the Participant in
                  accordance with an investment election made in the form, time,
                  and manner specified by the Company. The investment option so
                  selected by a Participant shall remain in effect until he
                  elects to change such election in accordance with Section 6.4
                  or receives distribution of his Accounts pursuant to Section
                  10.4. As of the date of receipt of such property by the

                  of the Participant who has made a Rollover Contribution as
                  provided in this Section 4.7 and shall be credited with such
                  assets on such date. A Rollover Contribution by a Participant
                  pursuant to this Section 4.7 shall not be deemed to be a
                  contribution of such Participant for any purpose of the Plan
                  and shall be fully vested in the Employee at all times.

         15. Section 4.9 of the Plan is hereby amended, effective as of February

                  contributions allocated to his Thrift Account as well as
                  contributions allocated to his Company Contribution Account
                  and Cash Option Account are to be invested in the time, form
                  and manner specified by the Company. The investment options so
                  elected by a Participant shall remain in effect until he files
                  another election change with respect to future contributions
                  in accordance with the provisions of the Plan. Amounts
                  credited to the Accounts of such Participant as of any date
                  prior to the date on which such change is to become effective
                  shall not be affected by any such change.

                  application is received by the Company, reduced by any
                  distributions or withdrawals from such Accounts occurring
                  since such Valuation Date.

                           (e) A loan shall be made from a Participant's

                  days under any of the terms of the loan.

                           (g) Such other terms and conditions, including

                                       2
<PAGE>

         accordance with its terms. The Trustee shall credit each payment of
         principal and interest to the Accounts of the Participant and allocate
         such repayment among the Accounts from which the loan was made and in
         accordance with the Participant's most recently filed investment
         election.

                  9.4 WITHDRAWALS PRIOR TO AGE 59-1/2. Subject to the provisions
         of this Section 9.4, on and after April 1, 1999, a Participant who is
         receiving compensation from an Employer or a Related Corporation and
         who has not attained age 59-1/2, may make a request in the form,
         manner, and time period prescribed by the Company for a withdrawal of
         an amount credited to his Accounts attributable to Participant
         Contributions, Rollover Contributions and Tax Deferred Contributions.
         Any such withdrawal shall be made first from a Participant's Thrift
         Account and then if the balance of his Thrift Account is fully
         withdrawn, from his Rollover Account, if any. A withdrawal from a
         Participant's Cash Option Account shall be permitted then only after
         the balances in his Thrift and Rollover Accounts have been withdrawn
         and only if (i) the reason for the withdrawal is to enable the
         Participant to meet an immediate and heavy financial need which cannot
         be met from other sources, including, but not limited to, sources
         outside the Plan and all other accounts and available loans under the
         Plan, and which meet the requirements of Section 401(k) of the Code and
         regulations thereunder, and (ii) would not exceed the lesser of the
         balance of such Cash Option Account or the amount required to meet the
         need for which the withdrawal is requested. Notwithstanding the
         foregoing, any such withdrawal of Tax Deferred Contributions from his
         Cash Option Account by a Participant who is under age 59-1/2 shall only
         be made for one of the following reasons:

                           (a) the payment of uninsured expenses incurred or
                  necessary for medical care, described in Section 213(d) of the
                  Code, of the Participant, or the Participant's spouse or
                  dependents;

                           (b) the purchase (excluding mortgage expenses) of a
                  principal residence for the Participant;

                           (c) the payment of tuition and related educational
                  fees for the next 12 months of post-secondary education for
                  the Participant, or the Participant's spouse, children or
                  dependents; or

                           (d) to prevent the eviction of the Participant from,
                  or a foreclosure on the mortgage of, the Participant's
                  principal residence.

         Moreover, in the event that a Participant who is under age 59-1/2
         withdraws any portion of his Cash Option Account, he shall not be able
         to have Tax Deferred Contributions made on his behalf for 12 months
         from the date of such withdrawal and may not make Tax Deferred
         Contributions for the taxable year immediately following the taxable
         year of the hardship withdrawal in excess of the applicable

                                       3
<PAGE>

         limit under Section 402(g) of the Code for such taxable year less the
         amount of his Tax Deferred Contributions for the taxable year of the
         hardship withdrawal.

                  9.5 WITHDRAWALS AFTER AGE 59-1/2. Subject to the provisions of
         this Section 9.5, a Participant who is receiving compensation from an
         Employer or a Related Corporation and who has attained at least age
         59-1/2, may make a written request in the form, manner, and time period
         prescribed by the Company for a withdrawal of an amount credited to his
         Accounts attributable to Participant Contributions, Rollover
         Contributions and Tax Deferred Contributions. Any such withdrawal shall
         be made first from the Participant's Thrift Account, then from his
         Rollover Account, if any, and then from his Cash Option Account.

         3. Section 10.4 of the Plan is hereby amended by the addition of a
sentence at the end thereof to provide as follows:

         Notwithstanding any other provision of the Plan to the contrary, upon
         the cessation of eligibility to participate in the Plan by any employee
         of a foreign subsidiary of the Company who is a nonresident alien and
         who has received no earned income within the meaning of Section 911(b)
         of the Code from an Employer which constitutes income from a source
         within the United States as defined in Section 861(a)(3) of the Code,
         the Company may, at the request of such Participant, cause the
         distribution of his Accounts to him; provided, however, that the
         balance of his Cash Option Account may not be distributed until he
         incurs a Settlement Date.

discretion to select Participants from among the key employees of the Company
who are members of a select group of highly compensated or management employees.

             b. BENEFITS FORMULA. The Company shall credit to the Capital
Accumulation Account of each Participant each year a deferred compensation
benefit equal to the following: (i) the Total Compensation of the Participant
for the preceding year; (ii) multiplied by the contribution percentage under the
Profit Sharing Plan (for 1994, such Profit Sharing Plan provided for
contributions of up to 15% of total contributions); (iii) the result of (i)and
(ii) shall then be reduced by the amount of the Maximum Contribution to the
Profit Sharing Plan; and (iv) the amount determined after (i),(ii) and (iii)
hereof shall then be multiplied by a fraction, the numerator of which shall be
the Maximum Contribution to the Profit Sharing Plan, reduced by the amount which
the Participant elected to receive in cash which otherwise would have been
contributed to the Profit Sharing Plan for such year, and the denominator of
which shall be the Maximum Contribution to the Profit Sharing Plan. The
application of this formula is illustrated by the examples set forth in Exhibit
B attached hereto and hereby made a part of this Agreement.

             c. CAPITAL ACCUMULATION ACCOUNT. The deferred compensation benefit
for a Participant pursuant to Section 3b shall be credited to such Participant's
Capital Accumulation Account on the Company's books and records at the times
determined by the Company. The balance in a Participant's Capital Accumulation
Account shall be equal to the aggregate of such Participant's deferred
compensation benefits under Section 3b of this Plan, plus any Earnings thereon.
The Company or the Trustee shall furnish each Participant or his or her
Beneficiary no less frequently than annually with a statement reflecting the
balance in his or her Capital Accumulation Account.

                                       3

Nothing herein shall be construed as conferring on any Participant or
Beneficiary any rights in or against amounts credited to his or her Capital
Accumulation Account. All amounts credited to a Capital Accumulation Account
shall constitute general assets of the Company.

         4. PAYMENT OF RETIREMENT. Death, and Disability Benefits, Forfeiture.

             a. AMOUNT. Upon a Participant's Retirement Date, death, or
termination of Long-Term Disability Benefits, the Company shall notify the
Trustee which shall commence payment of Retirement Benefits, Disability
Benefits, Post-Retirement or Post-Disability Death Benefits, or Pre-Retirement
Death Benefits, as the case may be, pursuant to the Payment Schedule attached as
Exhibit A of this Plan and in accordance with the Trust. Notwithstanding any
other provision herein and in accordance with the terms of the Trust, in the
event of a Participant's death, if the Trustee or the Company has one or more
life insurance policies on the life of the Participant, such policies and the
proceeds thereof shall constitute general assets of the Company and no person
(including but not limited to the Participant or his or her Beneficiary) shall
have or acquire any interest in such assets, and (i) if the Trustee owns or
otherwise holds such policies or proceeds, promptly after the Participant's
death, the Trustee shall return or pay to the Company any portion of the
proceeds thereof which would not be needed to make the payments due to such
deceased Participant's Beneficiary based on reasonable assumptions as determined
by the Company in its sole discretion, or (ii) if the Company owns or otherwise
holds such policies or proceeds, the Company shall be free to use or dispose of
any such policies and the proceeds therefrom in any manner which it shall
determine (provided that the Company shall continue to be obligated to make the
payments as required pursuant to the Payment Schedule attached as Exhibit A of
this Plan).

             b. FORFEITURE. A Participant shall forfeit any and all rights to
benefits under this Plan if:

                           (i)      the Company terminates his or her
                                    employment, with or without Cause; or

                           (ii)     if he or she voluntarily terminates his or
                                    her employment with the Company, prior to
                                    (i) attaining age 65, or (ii) attaining at
                                    least age 55 after having completed at least
                                    10 years of service with the Company.

                    c. PAYMENTS ONLY FROM CORPORATE ASSETS. The payment of any
benefits to a Participant or his or her Beneficiary shall be made from assets
which shall continue, for all purposes, to be a part of the general assets of
the Company; no person shall have or acquire any interest in such assets by
virtue of the provisions of this Plan or the Trust. To the extent that a
Participant or his or her Beneficiary acquires a right to receive payments from
the Company under the provisions hereof, such right shall be no greater than the
right of any unsecured general creditor of the Company.

         5. DETERMINATION OF BENEFITS, CLAIMS PROCEDURE AND ADMINISTRATION.

             a. DETERMINATION OF BENEFITS AND CLAIMS PROCEDURE. The Committee
shall make all determinations as to rights to benefits under this Plan and is
hereby designated as the named fiduciary. Subject to and in compliance with the
specific procedures contained in the applicable regulations promulgated under
the Employee Retirement Income Security Act of 1974, as amended: (i) any
decision by the Committee denying a claim for benefits under this Plan by a
Participant or other claimant shall be stated in writing by the Committee and
delivered or mailed to the claimant;(ii) each such notice shall set forth the
specific reasons for the denial, written to the best of the Committee's ability
in a manner that may be

                                       4
<PAGE>

understood without legal or actuarial counsel; and (iii) the Committee shall
afford a, reasonable opportunity to the claimant whose claim for benefits has
been denied, for a review of the decision denying such claim.

             b.    ADMINISTRATION OF PLAN.  Subject to the foregoing:  (i) the
Committee shall have full power and authority to interpret, construe and
administer the Plan, and (ii) the interpretation and construction of the Plan by
the Committee, and any action taken hereunder, shall be binding and conclusive
upon all parties in interest.

             c. NO LIABILITY FOR GOOD FAITH ACTIONS. Neither the Company, the
Committee, any member of the Committee, nor any other person acting on behalf of
the Company or the Committee, shall in any event be liable to any person for any
action taken or omitted to be taken in connection with the interpretation,
construction or administration of this Plan, so long as such action or omission
to act is made in good faith.

         6. NON-ASSIGNABILITY OF BENEFITS.

             Neither a Participant nor a Beneficiary shall have any power or
right to transfer, assign, anticipate, hypothecate or otherwise encumber any
part or all of the amounts payable hereunder. Such amounts shall not be subject
to seizure by any creditor of a Participant or his or her Beneficiary, by a
proceeding at law or in equity, nor transferable by operation of law in the
event of the bankruptcy or insolvency of a Participant or his or her
Beneficiary. Any such attempted assignment or transfer shall be void and shall
terminate the Participant's rights under the Plan; the Company shall thereupon
have no further liability hereunder with respect to such Participant.

         7. ATTORNEYS FEES.

             In the event of any legal and/or equitable action brought under
this Plan, the prevailing party shall be entitled to recover from the other
party reasonable attorneys fees and court costs.

         8. AMENDMENT.

             This Plan may not be amended, altered or modified on a retroactive
basis, except by a written instrument signed by the Company and the Participants
or their respective successors. However, the Company may amend or terminate the
Plan on a prospective basis, provided that no such amendment or termination
shall adversely affect a Participant's entitlement to benefits attributable to
amounts credited to his or her Capital Accumulation Account at the time of
amendment or termination of this Plan.

         9. NOTICES.

               Any notice, consent or demand required or permitted to be given
under the provisions of this Plan shall be in writing, and shall be signed by
the party giving or making the same. If such notice, consent or demand is mailed
to a party hereto, it shall be sent by United States certified or registered
mail, postage prepaid, addressed to such party's last known address as shown on
the records of the Company. The date of such mailing shall be deemed the date of

                                PAYMENT SCHEDULE

      All payments called for hereunder may be made by the Trustee or may be

amount of his or her Capital Accumulation Account balance in fifteen (15)annual
installments over a period of fifteen (15) years, with the first payment to be
made as of the first working day of January of the year following the year of
his or her Retirement Date. Each installment payment shall equal the quotient
determined by dividing the Participant's remaining Capital Accumulation Account
balance at the time of payment by the number of remaining installments
(including the current installment) . At the Company's option, the Company may
elect to pay, or direct the Trustee to pay, the Participant the balance of his
or her Capital Accumulation Account at any time as a lump sum, and thereafter
the Company shall have no further obligations to the Participant hereunder.

      2. DISABILITY BENEFITS. If a Participant terminates employment because of
Disability, after Long-Term Disability Benefits are no longer paid to the
Participant, the Trustee (or the Company directly) shall pay to the Participant,
as Disability Benefits, the amount of his or her Capital Accumulation Account
balance in fifteen (15) annual installments over a period of fifteen (15) years,
with the first payment to be made as of the first working day of January of the
year f following the year of the final Long-Term Disability Benefit payment.
Each installment payment shall equal the quotient determined by dividing the
Participant's remaining Capital Accumulation Account balance at the time of
payment by the number of remaining installments (including the current
installment). At the Company's option, the Company may elect to pay, or direct
the Trustee to pay, the Participant the balance of his or her Capital
Accumulation Account at any time, as a lump sum, and thereafter, the Company
shall have no further obligations to the Participant hereunder. During the
period of time that any Long-Term Disability Benefits are being paid, the
Participant's Capital Accumulation Account shall continue to accrue Earnings in
the same manner as if he or she were not Disabled, provided, however, that the
Company shall not make additional contributions under Section 3b of this Plan to
the Participant's Capital Accumulation Account during his or her Disability.

     3. PRE-RETIREMENT DEATH BENEFITS. If a Participant dies while employed by
the Company, the Trustee (or the Company directly) shall pay the amount of the

years with the first payment to be made as of the first working day of January
of the year following the year of the Participant's death. Each installment
payment shall equal the quotient determined by dividing the Participant's
remaining Capital Accumulation Account balance at the time of payment by the
number of remaining installments (including the current installment). At the
Company's option, the Company may elect to pay, or direct the Trustee to pay,
the Participant's Beneficiary the balance of his or her Capital Accumulation

after he has begun receiving Retirement Benefits or Disability Benefits but
before receiving all of such benefits, the Trustee (or the Company directly)

death (the Retirement Benefits or Disability Benefits having been paid under a
schedule of fifteen (15) annual installments over a period of fifteen (15) years
as provided in P. 1 or P. 2 of this Payment Schedule as applicable), provided
that payments after the Participant's death shall be made to the Participant's
Beneficiary. At the Company's option, the Company may elect to pay, or direct
the Trustee to pay, the Participant's Beneficiary the balance of the
Participant's Capital Accumulation Account at any time, as a lump sum, and
thereafter, the Company shall have no further obligations to the Participant's

preceding year is $222,500; the contribution percentage under the Profit Sharing
Plan is 15%; the Maximum Contribution to the Profit Sharing Plan is $22,500

of the Maximum Contribution to the Profit Sharing Plan in cash [an amount of
$11,250 based on $22,500 x 50% = $11,250] . In this case, the amount credited to

     EXAMPLE 2: Same as in Example 1 except the Participant elects not to
receive any of the Maximum Contribution to the Profit Sharing Plan in cash. In
this case, the amount credited to the Capital Accumulation Account would be
$10,875 determined as follows:

            Total Compensation                  $222,500
