               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3.  INCORPORATION OF DOCUMENTS BY REFERENCE.

         The following documents, which have been filed with the Securities and
Exchange Commission (the "Commission") by Serv-Tech, Inc. (the "Company"), are
incorporated by reference herein and made a part hereof:  (a) the Company's
Annual Report on Form 10-K for the year ended December 31, 1994, (b) the
Company's Quarterly Reports on Form 10-Q for the quarterly periods ended March
31, 1995, June 30, 1995 and September 30, 1995, and (c) the description of the
common stock, par value $.50 per share (the "Common Stock"), of the Company as
set forth under the caption "Description of Registrant's Securities to be
Registered" in the Company's Registration Statement on Form 8-A (File No.
0-17888) dated July 21, 1989, including any amendment or report filed for the
purpose of updating such description.

         All documents filed subsequent to the date hereof by the Company
pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange Act
of 1934 prior to the filing of a post-effective amendment which indicates that
all securities offered have been sold or which deregisters all securities then
remaining unsold, shall be deemed to be incorporated by reference herein and to
be part hereof from the date of the filing of such documents.

ITEM 4.  DESCRIPTION OF SECURITIES.

         Not applicable.

ITEM 5.  INTEREST OF NAMED EXPERTS AND COUNSEL.

         None.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Article 2.02-1 of the Texas Business Corporation Act contains detailed
provisions for indemnification of directors and officers of Texas corporations
against judgments, penalties, fines, settlements and reasonable expenses which
may be incurred in connection with any threatened, pending or completed
actions, suits or proceedings in which the director or officer is a named
defendant or respondent, whether civil, criminal, administrative, arbitrative
or investigative, any appeals in such an action, suit or proceeding, and any
inquiry or investigation that could lead to such an action, suit or proceeding.

         Article VI of the Company's Bylaws, as amended, provides for
indemnification of present and former directors and officers of the Company to
the full extent permitted by Texas law.  To the full extent permitted by Texas
law, the Company may pay for or reimburse expenses incurred by an indemnified
director or officer in advance of any final disposition.  In addition, the
Company is expressly authorized to purchase insurance on behalf of its
directors and officers against any liability arising out of their status as
directors and officers.



                                      2
<PAGE>   3
         Policies of insurance are maintained by the Company under which the
directors and officers of the Company are insured, within the limits and
subject to the limitations of the policies, against certain expenses in
connection with the defense of actions, suits or proceedings, and certain
liabilities which might be imposed as a result of such actions, suits or
proceedings, to which they are parties by reason of being or having been such
directors or officers.

         As permitted by Article 1302-7.06 of the Texas Miscellaneous
Corporation Laws Act, Article X of the Company's Restated Articles of
Incorporation, as amended, eliminates or limits the personal liability of
directors for monetary damages for an act or omission in the director's
capacity as a director, except for:  (i) a breach of a director's duty of
loyalty to the Company or its shareholders, (ii) an act or omission not in good
faith or that involves intentional misconduct or a knowing violation of the
law, (iii) a transaction from which a director received an improper benefit,
whether or not the benefit resulted from an action taken within the scope of
the director's office, (iv) an act or omission for which the liability of a
director is expressly provided for by statute, and (v) an act related to an
unlawful stock repurchase or payment of a dividend.

ITEM 9.  UNDERTAKINGS.

         (a)     The undersigned registrant hereby undertakes:

                 (1)      To file, during any period in which offers or sales
         are being made, a post-effective amendment to this registration
         statement:

                           (i)    To include any prospectus required by 
                 section 10(a)(3) of the Securities Act of 1933;

                          (ii)    To reflect in the prospectus any facts or
                 events arising after the effective date of the registration
                 statement (or the most recent post-effective amendment
                 thereof) which, individually or in the aggregate, represent a
                 fundamental change in the information set forth in the
                 registration statement;

                          (iii)   To include any material information with
                 respect to the plan of distribution not previously disclosed
                 in this registration statement or any material change to such
                 information in the registration statement.

                 Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do
         not apply if the information required to be included in a
         post-effective amendment by those paragraphs is contained in periodic
         reports filed by the registrant pursuant to section 13 or section
         15(d) of the Securities Exchange Act of 1934 that are incorporated by
         reference in the registration statement.

                 (2)      That, for the purpose of determining any liability
         under the Securities Act of 1933, each such post-effective amendment
         shall be deemed to be a new registration statement relating to the
         securities offered therein, and the offering of such securities at
         that time shall be deemed to be the initial bona fide offering
         thereof.

                 (3)      To remove from registration by means of a
         post-effective amendment any of the securities being registered which
         remain unsold at the termination of the offering.

         (b)     The undersigned registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act of 1933, each
filing of the registrant's annual report pursuant to Section 13(a) or Section
15(d) of the Securities Exchange Act of 1934 (and, where applicable, each
filing of an employee benefit plan's annual report pursuant to Section 15(d) of
the Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         (c)     Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the




                                      4
<PAGE>   5
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable.  In the event
that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer
or controlling person of the registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.

registrant certifies that it has reasonable grounds to believe that it meets
all of the requirements for filing on Form S-8 and has duly caused this

duly authorized, in the City of Houston, State of Texas, on November 21, 1995.

                         [SERV-TECH, INC. LETTERHEAD]


October 31, 1995


Serv-Tech, Inc.
5200 Cedar Crest Boulevard
Houston, TX 77087


Gentlemen:

In my capacity as Vice President, General Counsel and Secretary of Serv-Tech,
Inc., a Texas corporation (the "Company"), I have acted as counsel to the
Company in connection with the registration, pursuant to a Registration
Statement on Form S-8 being filed with the Securities and Exchange Commission
(the "Registration Statement") under the Securities Act of 1933, as amended, of
the offering and sale of up to 200,000 shares of the Company's common stock,
par value $.50 per share (the "Common Stock"), from time to time to the trustees
of the Serv-Tech, Inc. Consolidated Retirement Savings 401(k) Plan (the
"Plan") pursuant to the provisions of the Plan.

In such capacity I have examined documents of the Company, including its
Restated Articles of Incorporation, its By-Laws, as amended, and resolutions
adopted by its board of directors and committees thereof. I have also examined
the Registration Statement, together with the exhibits thereto, and such other
documents which I have deemed necessary for the purposes of expressing the
opinion contained herein.

Based upon the foregoing, I am of the opinion that the Common stock issued from
time to time to the trustees of the Plan pursuant to the provisions of the Plan
for a consideration at least equal to the par value of such Common Stock will
be validly issued, fully paid and non-assessable.

I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.


Sincerely,

/s/ FRANK PERRONE

                       CONSENT OF INDEPENDENT ACCOUNTANTS



We consent to the inclusion in this registration statement on Form S-8 of our
report dated February 17, 1995, on our audits of the consolidated financial

1.1      ACCRUED BENEFIT. The term Accrued Benefit means the value on any
         applicable date of the Participant's Account.

1.2      ACTIVE PARTICIPANT. The term Active Participant means any Participant
         who (a) performs duties as an Employee for the Employer, and (b) is
         not an Inactive Participant.

1.3      ACTUAL CONTRIBUTION PERCENTAGE. The term Actual Contribution
         Percentage means the average of the Actual Contribution Ratios of a
         specified group computed to the nearest one-hundredth of one percent.

1.4      ACTUAL CONTRIBUTION PERCENTAGE TEST.

         (A)     For each Plan Year, the Plan shall satisfy the contribution
                 percentage requirement described in section 401(m)(2) of the
                 Code and the regulations thereunder, which are incorporated
                 herein.

                 The Plan satisfies the Actual Contribution Percentage Test if:

                 (1)      The Actual Contribution Percentage for the group of
                          eligible Highly Compensated Employees is not more
                          than the Actual Contribution Percentage for the group
                          of all other eligible Employees multiplied by 1.25;
                          or

                 (2)      The excess of the Actual Contribution Percentage for
                          the group of eligible Highly Compensated Employees
                          over the Actual Contribution Percentage for the group
                          of all other eligible Employees is not more than two
                          percentage points, and the Actual Contribution
                          Percentage for the group of eligible Highly
                          Compensated Employees is not more than the Actual
                          Contribution Percentage for the group of all other
                          eligible Employees multiplied by two.

         (B)     Special Rules.

                 (1)      Matching Contributions and Qualified Nonelective
                          Contributions will be considered for a Plan Year only
                          if allocated to the Employee's Account as of any date
                          within the Plan Year being tested and only if made
                          before the last day of the twelve month period
                          immediately following the Plan Year to which such
                          contributions relate.

                 (2)      A Matching Contribution that is forfeited to correct
                          Excess Aggregate Contributions, or because the
                          contribution to which it relates is treated as an
                          Excess Contribution, Excess Deferral,  or Excess
                          Aggregate Contribution, shall not be taken into
                          account for purposes of the Actual Contribution
                          Percentage Test.

                 (3)      The Employer shall maintain records sufficient to
                          demonstrate satisfaction of the Actual Contribution
                          Percentage Test, including records showing the extent
                          to which Qualified Nonelective Contributions and
                          Elective Deferral Contributions are taken into
                          account.

1.5      ACTUAL CONTRIBUTION RATIO.

         (A)     An Employee's Actual Contribution Ratio is the sum of the
                 Contribution Percentage Amounts allocated to the Employee's
                 Account for the Plan Year (including any amounts required to
                 be taken into account under subparagraphs (B) (1) and (B) (2)
                 of this section) divided by the Employee's Compensation for
                 the Plan Year. If no Matching Contributions, Qualified
                 Nonelective Contributions, or Elective Deferral Contributions
                 are taken into account with respect to an eligible Employee,
                 the Actual Contribution Ratio of the Employee is zero.

         (B)     Special Rules.

                 (1)      In the event that this Plan is aggregated with one or
                          more plans for purposes of section 410(b) of the Code
                          (other than for purposes of the average benefit
                          percentage test), or if one or more other plans
                          satisfy the requirements of section 410(b) of the
                          Code (other than the average benefit percentage test)
                          only if aggregated with this Plan, then this section
                          shall be applied by determining the Actual
                          Contribution Ratios of Employees as if all such plans
                          were a single plan. Plans may be aggregated only if
                          they have the same Plan Year.

                 (2)      The Actual Contribution Ratio of a Highly Compensated
                          Employee who is eligible to participate in more than
                          one plan of the Employer to which employee
                          contributions or Matching Contributions are made
                          shall be calculated by treating all such plans in
                          which the Employee is eligible to participate as one
                          plan. For Plan Years beginning after December 31,
                          1988, if a Highly Compensated Employee participates
                          in two or more plans that have different plan years,
                          all plans ending with or within the same calendar
                          year shall be treated as a single plan. However,
                          plans that are not permitted to be aggregated under
                          Treasury Regulation section 1.401(m)-1(b)(3)(ii)
                          shall not be aggregated for purposes of this section.

                 (3)      For purposes of determining the Actual Contribution
                          Ratio of a Participant who is a 5-percent owner or
                          one of the ten most highly-paid Highly Compensated
                          Employees, the Contribution Percentage Amounts and
                          Compensation of such Participant shall include the
                          Contribution Percentage Amounts (including any
                          amounts required to be taken into account under
                          subparagraphs (B) (1) and (B) (2) of this section)
                          and Compensation for the Plan Year of all Family
                          Members.

                          If the Participant is required to be aggregated as a
                          member of more than one family group under the Plan,
                          all eligible Employees who are members of those
                          family groups that include that Employee are
                          aggregated as one family group.

                          Family Members, with respect to Highly Compensated
                          Employees, shall be disregarded as separate Employees
                          in determining the Actual Contribution Ratio both for
                          Participants who are Nonhighly Compensated Employees
                          and for Participants who are Highly Compensated
                          Employees.

                 (4)      The determination and treatment of the Actual
                          Contribution Ratio amounts of any Participant shall
                          satisfy such other requirements as may be prescribed
                          by the Secretary of the Treasury.

1.6      ACTUAL DEFERRAL PERCENTAGE. The term Actual Deferral Percentage means
         the average of the Actual Deferral Ratios of a specified group,
         computed to the nearest one-hundredth of one percent.

1.7      ACTUAL DEFERRAL PERCENTAGE TEST.

         (A)     For each Plan Year, the Plan shall satisfy the Actual Deferral
                 Percentage Test described in section 401(k)(3) and the
                 regulations thereunder, which are herein incorporated by
                 reference.

                 The Plan satisfies the Actual Deferral Percentage Test for a 
                 Plan Year only if:

                 (1)      The Actual Deferral Percentage for the group of
                          eligible Highly Compensated Employees is not more
                          than the Actual Deferral Percentage for the group of
                          all other eligible Employees multiplied by 1.25; or

                 (2)      The excess of the Actual Deferral Percentage for the
                          group of eligible Highly Compensated Employees over
                          the Actual Deferral Percentage for the group of all
                          other eligible Employees is not more than two
                          percentage points, and the Actual Deferral Percentage
                          for the group of eligible Highly Compensated
                          Employees is not more than the Actual Deferral
                          Percentage for the group of all other eligible
                          Employees multiplied by two.

         (B)     Special Rules.

                 (1)      For purposes of determining the Actual Deferral
                          Percentage Test, Elective Deferral Contributions,
                          Qualified Nonelective Contributions, and Qualified
                          Matching Contributions must be allocated to the
                          Employee's Account as of a date within the Plan Year
                          being tested and must be made before the last day of
                          the twelve-month period immediately following the
                          Plan Year to which such contributions relate.

                 (2)      The Excess Deferrals of a Highly Compensated Employee
                          shall be taken into account for purposes of the
                          Actual Deferral Percentage Test. Conversely, the
                          Excess Deferrals of an Employee who is a Nonhighly
                          Compensated Employee shall not be taken into account
                          for purposes of the Actual Deferral Percentage Test.

                 (3)      The Employer shall maintain records sufficient to
                          demonstrate satisfaction of the Actual Deferral
                          Percentage Test, including the extent to which
                          Qualified Nonelective Contributions and Qualified
                          Matching Contributions are taken into account.

1.8      ACTUAL DEFERRAL RATIO.

         (A)     An Employee's Actual Deferral Ratio for the Plan Year is the
                 sum of the Employee's Deferral Percentage Amounts allocated to
                 the Employee's Account for the Plan Year (including any
                 amounts required to be taken into account under subparagraphs
                 (B) (1) and (B) (2) of this section), divided by the
                 Employee's Compensation taken into account for the Plan Year.
                 If an eligible Employee makes no Elective Deferral
                 Contributions, and no Qualified Matching Contributions or
                 Qualified Nonelective Contributions are taken into account
                 with respect to the Employee, the Actual Deferral Ratio of the
                 Employee is zero.

         (B)     Special Rules.

                 (1)      In the event that this Plan is aggregated with one or
                          more plans for purposes of section 410(b) of the Code
                          (other than for purposes of the average benefit
                          percentage test), or if one or more other plans
                          satisfy the requirements of section 410(b) of the
                          Code (other than the average benefit percentage test)
                          only if aggregated with this Plan, then this section
                          shall be applied by determining the Actual Deferral
                          Ratio of Employees as if all such plans





                                       3
<PAGE>   6
                          were a single plan. Plans may be aggregated only if 
                          they have the same Plan Year.

                 (2)      The Actual Deferral Ratio of a Highly Compensated
                          Employee who is eligible to participate in more than
                          one cash or deferred arrangement (as described in
                          section 401(k) of the Code) of the same Employer
                          shall be calculated by treating all the cash or
                          deferred arrangements in which the Employee is
                          eligible to participate as one arrangement. If the
                          cash or deferred arrangements that are treated as a
                          single arrangement under the preceding sentence are
                          parts of plans that have different Plan Years, the
                          cash or deferred arrangements are treated as a single
                          arrangement with respect to the Plan Years ending
                          with or within the same calendar year.  However,
                          plans that are not permitted to be aggregated under
                          Treasury Regulation section 1.401(k)-1(b)(3)(ii)(B)
                          are not aggregated for purposes of this section.

                 (3)      For purposes of determining the Actual Deferral Ratio
                          of a Participant who is a 5 percent owner or one of
                          the 10 most Highly Compensated Employees, the
                          Deferral Percentage Amounts and Compensation of such
                          Participant shall include the Deferral Percentage
                          Amounts (including any amounts required to be taken
                          into account under subparagraphs (B) (1) and (B) (2)
                          of this section) and Compensation for the Plan Year
                          of Family Members.

                          If an Employee is required to be aggregated as a
                          member of more than one family group under the Plan,
                          all eligible Employees who are members of those
                          family groups that include that Employee are
                          aggregated as one family group.

                          Family Members, with respect to such Highly
                          Compensated Employees, shall be disregarded as
                          separate Employees in determining the Actual Deferral
                          Percentage both for Participants who are Non-highly
                          Compensated Employees and for Participants who are
                          Highly Compensated Employees.

                 (4)      The determination and treatment of the Actual
                          Deferral Ratio amounts of any Participant shall
                          satisfy such other requirements as may be prescribed
                          by the Secretary of the Treasury.

1.9      ANNUITY. The term Annuity means a series of payments made over a
         specified period of time which, for a fixed annuity are, of equal,
         specified amounts, and for a variable annuity increase or decrease to
         reflect changes in investment performance of the underlying portfolio.

1.10     ANNUITY STARTING DATE. The term Annuity Starting Date means the first
         day of the first period for which an amount is payable as an Annuity.
         In the case of a benefit not payable in the form of an Annuity, the
         term Annuity Starting Date means the first day on which all events
         have occurred which entitle the Participant to such benefit.

1.11     BENEFICIARY. The Participant's Spouse is the designated Beneficiary of
         the Participant's entire Vested Interest. However, each Participant
         shall have the right to designate another Beneficiary and to specify
         the form of death benefit the Beneficiary is to receive, subject to
         the requirements of the "Qualified Election" provisions of Article
         VIII, Joint and Survivor Annuity Requirements. The Participant may
         change the Beneficiary and/or the form of death benefit at any time,
         subject to the requirements of the "Qualified Election" provisions of
         Article VIII, Joint and Survivor Annuity Requirements.

         If any distribution hereunder is made to a Beneficiary in the form of
         an Annuity, and if such Annuity provides for a death benefit, then
         such Beneficiary shall also have the right to designate a Beneficiary
         





                                       4
<PAGE>   7
         and to change that Beneficiary from time to time. As an alternative to
         receiving the benefit in the form of an Annuity, the Beneficiary may
         elect to receive a single cash payment or any other form of payment
         provided for in the Plan.

         If a Beneficiary has not been designated, or if a Beneficiary
         designation or change of Beneficiary designation does not meet the
         requirements of the "Qualified Election" provisions of Article VIII,
         Joint and Survivor Annuity Requirements, (including any designation
         made prior to August 23, 1984 by a married Participant who has an Hour
         of Service on or after August 23, 1984), or if no designated
         Beneficiary survives the Participant, the Participant's entire Vested
         Interest shall be distributed to the Participant's Spouse, if living;
         otherwise in equal shares to any surviving children of the
         Participant. In the event none of the above named individuals survives
         the Participant, the Participant's entire Vested Interest shall be
         paid to the executor or administrator of the Participant's estate.

1.12     BOARD OF DIRECTORS. The term Board of Directors means the Employer's
         board of directors or other comparable governing body.

1.13     CODE. The term Code means the Internal Revenue Code of 1986, as
         amended from time to time.

1.14     COMPENSATION

         (A)     Except as otherwise provided in the Plan, the term
                 Compensation means wages within the meaning of section 3401(a)
                 of the Code for the purposes of income tax withholding at the
                 source but determined without regard to any rules that limit
                 the remuneration included in wages based on the nature or
                 location of the employment or the services performed (such as
                 the exception for agricultural labor in section 3401(a)(2) of
                 the Code).

                 Notwithstanding the foregoing, Compensation shall be reduced
                 by all of the following items (even if includible in gross
                 income): reimbursements or other expense allowances, fringe
                 benefits (cash and noncash), moving expenses, deferred
                 compensation, and welfare benefits.

         (B)     Compensation shall include only that Compensation which is
                 actually paid to the Participant during the determination
                 period. Except as provided elsewhere in the Plan, the
                 determination period shall be the Plan Year.

         (C)     Compensation shall include any amount which is contributed by
                 the Employer pursuant to a salary reduction agreement and
                 which is not includible in the gross income of the employee
                 under sections 125, 402(e)(3), 402(h), or 403(b) of the Code;
                 Compensation deferred under an eligible deferred compensation
                 plan within the meaning of section 457(d) of the Code; and
                 employee contributions described in section 414(h)(2) of the
                 Code that are picked up by the employing unit and, thus, are
                 treated as employer contributions.

         (D)     The annual Compensation of each Participant taken into account
                 for determining all benefits provided under the Plan for any
                 determination period shall not exceed $200,000. This
                 limitation shall be adjusted by the Secretary of the Treasury
                 at the time and in the same manner as under section 415(d) of
                 the Code, except that the dollar increase in effect on January
                 1 of any calendar year is effective for determination periods
                 beginning in such calendar year and the first adjustment to
                 the $200,000 limitation is effected on January 1, 1990. If the
                 period for determining Compensation used in calculating an
                 Employee's allocation for a determination period is a short
                 Plan Year (i.e., shorter than 12 months), the annual
                 Compensation limit is an amount equal to the otherwise
                 applicable annual Compensation limit multiplied by a fraction,
                 the numerator of which is the number of months in the short
                 Plan Year, and the denominator of which is 12.

                 In determining the Compensation of a Participant for purposes
                 of this limitation, the rules of section 414(q)(6) of the Code
                 shall apply, except in applying such rules, the term "family"
                 shall include only the Spouse of the Participant and any
                 lineal descendants of the Participant who have not attained
                 age 19 before the close of the year. If, as a result of the
                 application of such rules, the adjusted $200,000 limitation is
                 exceeded, then either the limitation shall be prorated among
                 the affected individuals in proportion to each such
                 individual's Compensation as determined under this section
                 prior to the application of this limitation, or the limitation
                 shall be allocated among the affected individuals in an
                 objective and nondiscriminatory manner based on a reasonable,
                 good faith interpretation of section 401(a)(17) of the Code.
                 The method chosen in the preceding sentence shall be uniformly
                 applied to all affected individuals in a Plan Year and shall
                 be applied consistently from year to year.

                 If Compensation for any prior determination period is taken
                 into account in determining an Employee's allocations or
                 benefits for the current determination period, the
                 Compensation for such prior determination period is subject to
                 the applicable annual Compensation limit in effect for that
                 prior year. For this purpose, for years beginning before
                 January 1, 1990, the applicable annual Compensation limit is
                 $200,000.

         (E)     In addition to other applicable limitations set forth in the
                 Plan, and notwithstanding any other provision of the Plan to
                 the contrary, for Plan Years beginning on or after January 1,
                 1994, the annual Compensation of each Employee taken into
                 account under the Plan shall not exceed the OBRA '93 annual
                 Compensation limit. The OBRA '93 annual Compensation limit is
                 $150,000, as adjusted by the Commissioner for increases in the
                 cost of living in accordance with section 401(a)(17)(B) of the
                 Code. The cost-of-living adjustment in effect for a calendar
                 year applies to any period, not exceeding 12 months, over
                 which Compensation is determined (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. For
                 Plan Years beginning on or after January 1, 1994, any
                 reference in this Plan to the limitation under section
                 401(a)(17) of the Code shall mean the OBRA '93 annual
                 Compensation limit set forth in this provision. If
                 Compensation for any prior determination period is taken into
                 account in determining an employee's benefits accruing in the
                 current Plan Year, the Compensation for that prior
                 determination period is subject to the OBRA '93 annual
                 Compensation limit in effect for that prior determination
                 period. For this purpose, for determination periods beginning
                 before the first day of the first Plan Year beginning on or
                 after January 1, 1994, the OBRA '93 annual Compensation limit
                 is $150,000.

1.15     CONSIDERED NET PROFITS. The term Considered Net Profits means the
         entire amount of the accumulated or current operating profits
         (excluding capital gains from the sale or involuntary conversion of
         capital or business assets) of the Employer after all expenses and
         charges other than (i) the contributions made by the Employer to the
         Plan, and (ii) federal or state or local taxes based upon or measured
         by income, as determined by the Employer, either on an estimated basis
         or a final basis, in accordance with the generally accepted accounting
         principles used by the Employer. When the amount of Considered Net
         Profits has been determined by the Employer, and the contributions are
         made by the Employer on the basis of such determination, for any Plan
         Year, such determination and contribution shall be final and
         conclusive and shall not be subject to change because of any
         adjustments in income or expense which may be required by the Internal
         Revenue Service or otherwise. Such determination and contribution
         shall not be open to question by any Participant either before or
         after the contributions by the Employer have been made.

1.16     CONTRIBUTION PERCENTAGE AMOUNTS. The term Contribution Percentage
         Amounts means the sum of the Matching Contributions and Qualified
         Matching Contributions (to the extent not taken into


                                       6
<PAGE>   9
         account for purposes of the Actual Deferral Percentage Test) made
         under the Plan on behalf of the Employee for the Plan Year. The term
         Contribution Percentage Amounts also includes Qualified Nonelective
         Contributions and Elective Deferral Contributions treated as Matching
         Contributions and taken into account in determining the Employee's
         Actual Contribution Ratio for the Plan Year.

1.17     CONTRIBUTION PERIOD. The term Contribution Period means that regular
         period specified by the Employer in Article IV for which contributions
         shall be made.

1.18     DEFERRAL PERCENTAGE AMOUNTS. The term Deferral Percentage Amounts
         means an Employee's Elective Deferral Contributions for the Plan Year.
         The term Deferral Percentage Amounts also includes Qualified
         Nonelective Contributions and Qualified Matching Contributions treated
         as Elective Deferral Contributions and taken into account in
         determining the Employee's Actual Deferral Ratio for the Plan Year.

1.19     DISABILITY. The term Disability means a Participant's incapacity to
         engage in any substantial gainful activity because of a medically
         determinable physical or mental impairment which can be expected to
         result in death, or to be of long, continued and indefinite duration.
         Such determination of Disability shall be made by the Administrator
         with the advice of competent medical authority. All Participants in
         similar circumstances will be treated alike.

1.20     DISABILITY RETIREMENT DATE. The term Disability Retirement Date means
         the first day of the month after the Plan Administrator has determined
         that a Participant's incapacity is a Disability.

1.21     EARLY RETIREMENT DATE. The term Early Retirement Date means the first
         day of the month coinciding with or next following the date a
         Participant is separated from Service with the Employer on or after
         the date he attains age 55 and has seven Years of Service for any
         reason other than death or Disability, provided that on such date the
         Participant has not attained his Normal Retirement Age.

1.22     EFFECTIVE DATE. The term Effective Date means January 1, 1993.

1.23     ELECTIVE DEFERRAL CONTRIBUTION. The term Elective Deferral
         Contribution means any Employer Contribution made to the Plan at the
         election of the Participant, in lieu of cash compensation, and
         includes contributions made pursuant to a Salary Deferral Agreement or
         other deferral mechanism.

         Solely for purposes of the dollar limitation specified in section
         402(g) of the Code, with respect to any taxable year, a Participant's
         Elective Deferral Contributions are the sum of all employer
         contributions made on behalf of such Participant pursuant to an
         election to defer under any qualified cash or deferred arrangement as
         described in section 401(k) of the Code, any simplified employee
         pension cash or deferred arrangement described in section 402(h)(1)(B)
         of the Code, any plan as described under section 501(c)(18) of the

         deferrals properly distributed as excess annual additions.

1.24     EMPLOYEE. The term Employee means an individual who performs services
         for the Employer and who is either a common law employee of the
         Employer or a self-employed individual/owner employee treated as an

         includes a Leased Employee who is treated as an Employee of the
         Employer-recipient pursuant to the provisions of Code section 414(n)
         or 414(o). For purposes of determining the Highly Compensated
         Employees, the Employer may elect, on a reasonable and consistent
         basis, to treat such Leased Employees covered by a plan described in
         Code





                                       7

         contributions to the Plan or any other plan that are designated or
         treated at the time of contribution as after-tax Employee

         attributable earnings and losses are allocated. Such term includes
         Employee Contributions applied to the purchase of life insurance
         policies.

         Such term does not include buy-back of benefits described in code

1.26     EMPLOYER. The term Employer means Serv-Tech, Inc., Seco Industries,
         Inc., Talbert & Associates, Inc. and Hartney Industrial Services
         Corporation and any successor organization to such Employer which
         elects to continue the Plan. In the case of a group of employers which
         constitutes a controlled group of corporations (as defined in Code
         section 414(b)), or which constitutes trades or businesses (whether or
         not incorporated) which are under common control (as defined in Code
         section 414(c)), or which constitutes an affiliated service group (as
         defined in Code section 414(m)), all such employers shall be
         considered a single employer for purposes of participation, vesting,
         Top-Heavy provisions and determination of Highly Compensated
         Employees.

1.27     EMPLOYER CONTRIBUTION. The term Employer Contribution means any
         contribution made to the Plan by the Employer on behalf of a
         Participant, other than a Rollover Contribution or a mandatory or
         voluntary contribution made to the Plan by the Employee that is
         treated at the time of contribution as an after-tax employee
         contribution.

1.28     ENTRY DATE. The term Entry Date means either the Effective Date or the
         January 1, April 1, July 1 or October 1 thereafter when an Employee
         who has fulfilled the eligibility requirements commences participation
         in the Plan.


         Any Employee who has satisfied the maximum eligibility requirements
         permissible under ERISA, shall be eligible to commence participation
         in this Plan no later than the earlier of (A) or (B) below, as
         applicable, provided that the Employee has not separated from the
         Service of the Employer:

         (A)     The first day of the first Plan Year beginning after the date
                 on which the Employee satisfied such requirements; or

         (B)     The date six months after the date on which the Employee
                 satisfied such requirements.

         If an Employee is not in the active Service of the Employer as of his
         initial Entry Date, his subsequent Entry Date shall be the date he
         returns to the active Service of the Employer, provided he still meets
         the eligibility requirements. If an Employee does not enroll as a
         Participant as of his initial Entry Date, his subsequent Entry Date
         shall be the applicable Entry Date as specified above when the
         Employee actually enrolls as a Participant.

1.29     ERISA. The term ERISA means the Employee Retirement Income Security
         Act of 1974 (PL 93-406) as it may be amended from time to time, and
         any regulations issued pursuant thereto as such Act and such
         regulations affect this Plan and Trust.

1.30     EXCESS AGGREGATE CONTRIBUTIONS.

         (A)     The term Excess Aggregate Contributions means, with respect to
                 any Plan Year, the excess of the aggregate amount of the
                 Contribution Percentage Amounts actually made on behalf of
                 





                                       8
<PAGE>   11
                 Highly Compensated Employees for the Plan Year (including any 
                 amounts required to be taken into account under subparagraphs 
                 (B) (1) and (B) (2) of Section 1.5 of the Plan), over the 
                 maximum amount of contributions permitted under the Actual 
                 Contribution Percentage Test.  The amount of Excess Aggregate 
                 Contributions for each Highly Compensated Employee is 
                 determined by using the method described in paragraph (B) of 
                 this section.

         (B)     The amount of Excess Aggregate Contributions for a Highly
                 Compensated Employee for a Plan Year is the amount (if any) by
                 which the Employee's Matching Contributions must be reduced
                 for the Employee's Actual Contribution Ratio to equal the
                 highest permitted Actual Contribution Ratio under the Plan.

                 To calculate the highest permitted Actual Contribution Ratio
                 under the Plan, the Actual Contribution Ratio of the Highly
                 Compensated Employee with the highest Actual Contribution
                 Ratio is reduced by the amount required to cause the
                 Employee's Actual Contribution Ratio to equal the ratio of the
                 Highly Compensated Employee with the next highest Actual
                 Contribution Ratio. If a lesser reduction would enable the
                 Plan to satisfy the Actual Contribution Percentage Test, only
                 this lesser reduction may be made. This process shall be
                 repeated until the Plan satisfies the Actual Contribution
                 Percentage Test.  The highest Actual Contribution Percentage
                 Ratio remaining under the Plan after leveling is the highest
                 permitted Actual Contribution Ratio.

                 For each Highly Compensated Employee, the amount of Excess
                 Aggregate Contributions for a Plan Year is equal to the total
                 Contribution Percentage Amounts (including any amounts
                 required to be taken into account under subparagraphs (B) (1)
                 and (B) (2) of Section 1.5 of the Plan), minus the amount
                 determined by multiplying the Employees's highest permitted
                 Actual Contribution Ratio (determined after application of
                 this section) by the compensation used in determining the
                 ratio.

1.31     EXCESS CONTRIBUTION.

         (A)     The term Excess Contribution means, with respect to a Plan
                 Year, the excess of Deferral Percentage Amounts made on behalf
                 of eligible Highly Compensated Employees for the Plan Year
                 (including any amounts required to be taken into account under
                 subparagraphs (B) (1) and (B) (2) of Section 1.8 of the Plan)
                 over the maximum amount of such contributions permitted under
                 the Actual Deferral Percentage Test for the Plan Year. The
                 amount of Excess Contributions for each Highly Compensated
                 Employee is determined by using the method described in
                 paragraph (B) of this section.

         (B)     The amount of Excess Contributions for a Highly Compensated
                 Employee for a Plan Year is the amount (if any) by which the
                 Employee's Elective Deferral Contributions must be reduced for
                 the Employee's Actual Deferral Ratio to equal the highest
                 permitted Actual Deferral Ratio under the Plan.

                 To calculate the highest permitted Actual Deferral Ratio under
                 the Plan, the Actual Deferral Ratio of the Highly Compensated
                 Employee with the highest Actual Deferral Ratio is reduced by
                 the amount required to cause the Employee's Actual Deferral
                 Ratio to equal the ratio of the Highly Compensated Employee
                 with the next highest Actual Deferral Ratio. If a lesser
                 reduction would enable the arrangement to satisfy the Actual
                 Deferral Percentage Test, only this lesser reduction shall be
                 made.  This process shall be repeated until the cash or
                 deferred arrangement satisfies the Actual Deferral Percentage
                 Test. The highest Actual Deferral Ratio remaining under the
                 Plan after leveling is the highest permitted Actual Deferral
                 Ratio.

1.32     EXCESS DEFERRALS. The term Excess Deferrals means those Elective
         Deferral Contributions that are includible in a Participant's gross

         Participant's  Elective Deferral Contributions for a taxable year 
         exceed the dollar limitation under such Code section.

1.33     FAIL-SAFE CONTRIBUTION. The term Fail-Safe Contribution means a
         Nonelective Contribution, designated by the Employer at the time of
         contribution as a Qualified Nonelective Contribution, which is
         contributed to the Plan solely for the purposes of satisfying either
         the Actual Deferral Percentage Test or the Actual Contribution
         Percentage Test and is made in accordance with the provisions of
         Article IV of this Plan.

1.34     FAMILY MEMBER. The term Family Member means, with respect to any
         Employee, such Employee's Spouse and lineal ascendants and descendants

         However, if an Active Participant dies prior to attaining his Normal
         Retirement Age, his Vesting Percentage shall be 100%.

                                   ARTICLE II
                                    SERVICE



2.1      SERVICE. The term Service means active employment with the Employer as
         an Employee. For purposes of determining Service, employment with any
         company which is under common control with the Employer as specified
         in section 414 of the Internal Revenue Code shall be treated as
         employment with the Employer.

2.2      ABSENCE FROM EMPLOYMENT. Absence from employment on account of a leave
         of absence authorized by the Employer pursuant to the Employer's
         established leave policy will be counted as employment with the
         Employer provided that such leave of absence is of not more than two
         years' duration. Absence from employment on account of active duty
         with the Armed Forces of the United States will be counted as
         employment with the Employer. If the Employee does not return to
         active employment with the Employer, his Service will be deemed to
         have ceased on the date the Administrator receives notice that such
         Employee will not return to the active Service of the Employer. The
         Employer's leave policy shall be applied in a uniform and
         nondiscriminatory manner to all Participants under similar
         circumstances.

2.3      HOUR OF SERVICE. The term Hour of Service means a period of Service
         during which an Employee shall be credited with one Hour of Service as
         described in (A), (B), (C), and (D) below:

         (A)     Each hour for which an Employee is directly or indirectly
                 paid, or entitled to payment, by the Employer for the
                 performance of duties. These hours shall be credited to the
                 Employee for the computation period or periods in which the
                 duties are performed; and

         (B)     Each hour for which an Employee is directly or indirectly
                 paid, or entitled to payment, by the Employer for reasons
                 (such as vacation, sickness or Disability) other than for the
                 performance of duties. Hours under this Subsection shall be
                 calculated and credited pursuant to section 2530.200b-2 of the
                 Department of Labor Regulations which are incorporated herein
                 by this reference; and

         (C)     Each hour for which back pay, irrespective of mitigation of
                 damages, has been either awarded or agreed to by the Employer.
                 These hours shall be credited to the Employee for the
                 computation period or periods to which the award or agreement
                 pertains rather than the computation period in which the
                 award, agreement or payment is made; and

         (D)     Each hour for which an Employee is on an authorized unpaid
                 leave (such as service with the Armed Forces, jury duty,
                 educational leave). These hours shall be credited to the
                 Employee for the computation period or periods in which such
                 authorized leave takes place. However, no more than 501 hours
                 shall be credited under this subparagraph (D).

         Hours of Service will be credited for employment with other members of
         an affiliated service group (under Internal Revenue Code section
         414(m)), a controlled group of corporations (under Internal Revenue
         Code section 414(b)), or a group of trades or businesses under common
         control (under Internal Revenue Code section 414(c)), of which the
         adopting employer is a member. Hours of Service will also be credited
         for any individual considered an Employee under Internal Revenue Code
         section 414(n).

         Solely for purposes of determining whether a One-Year Break in
         Service, as defined in Section 2.4, for





                                       16
<PAGE>   19
         participation and vesting purposes has occurred in a computation
         period, an individual who is absent from work for maternity or
         paternity reasons shall receive credit for the Hours of Service which
         would otherwise have been credited to such individual but for such
         absence, or in any case in which such hours cannot be determined,
         eight Hours of Service per day of such absence. For purposes of this
         paragraph, an absence from work for maternity or paternity reasons
         means an absence (1) by reason of the pregnancy of the individual, (2)
         by reason of a birth of a child of the individual, (3) by reason of
         the placement of a child with the individual in connection with the
         adoption of such child by such individual, or (4) for purposes of
         caring for such child for a period beginning immediately following
         such birth or placement. The Hours of Service credited under this
         paragraph shall be credited (1) in the computation period in which the
         absence begins if the crediting is necessary to prevent a Break in
         Service in that period, or (2) in all other cases, in the following
         computation period.

2.4      ONE-YEAR BREAK IN SERVICE. Except as provided below regarding
         eligibility, the term One-Year Break in Service means any Plan Year
         during which an Employee fails to complete more than 500 Hours of
         Service.

2.5      DETERMINING VESTING PERCENTAGE. Vesting credit shall be given for each
         Year of Service except those periods specified in Section 2.7.

         If a Participant completes less than 1,000 Hours of Service during a
         Plan Year while remaining in the Service of the Employer, his Vesting
         Percentage shall not be increased for such Plan Year. However, at such
         time as the Participant again completes at least 1,000 Hours of
         Service in any subsequent Plan Year, his Vesting Percentage shall then
         take into account all Year(s) of Service with the Employer except
         those specified in Section 2.7.

         If an individual who ceases to be an Employee and is subsequently
         rehired as an Employee enrolls (or re-enrolls) in the Plan, upon his
         participation (or subsequent participation) his Vesting Percentage
         shall then take into account all Year(s) of Service except those
         specified in Section 2.7.

2.6      YEAR(S) OF SERVICE. The term Year(s) of Service means a
         12-consecutive-month period during which an Employee has completed at
         least 1,000 Hours of Service.

         (A)     Eligibility Computation Period.

                 For purposes of determining Years of Service and Breaks in
                 Service for eligibility, the twelve-consecutive-month period
                 shall begin with the date on which an Employee's employment
                 commenced and, where additional periods are necessary, on
                 succeeding anniversaries of his employment commencement date.
                 The employment commencement date is the date on which the
                 Employee first performs an Hour of Service for the Employer
                 maintaining the Plan.

                 The eligibility requirement specified in Article III is one or
                 more full Years of Service. Such requirement shall be met upon
                 completion of at least 1,000 Hours of Service for each Year of
                 Service specified.

         (B)     Vesting Computation Period.

                 In computing Years of Service and Breaks in Service for
                 vesting, the 12-consecutive-month period shall be the Plan
                 Year. However, active participation as of the last day of the
                 Plan Year is not required in order for a Participant to be
                 credited with a Year of Service for vesting purposes.

                 For purposes of the Vesting Computation Period, if any Plan
                 Year is less than 12-consecutive





                                       17
<PAGE>   20
                 months, and if a Participant would have been credited with a 
                 Year of Service during the 12-consecutive-month period 
                 beginning on the first day of the short Plan Year, then the 
                 Participant will receive a Year of Service for the short Plan 
                 Year. The Participant receives credit for an additional Year 
                 of Service if the Participant would have been credited with a 
                 Year of Service for the Plan Year immediately following the 
                 short Plan Year.

         (C)     Contribution Computation Period.

                 For purposes of determining a Participant's eligibility to
                 receive a contribution made by the Employer, pursuant to
                 Article IV, which is conditioned upon a Year of Service
                 requirement, the twelve-consecutive-month period shall be any
                 Plan Year during which the Active Participant is credited with
                 at least 1,000 Hours of Service. However, when an Employee
                 first becomes a Participant or resumes active participation in
                 the Plan following a One-Year Break in Service on a date other
                 than the first day of the Plan Year, all Hours of Service
                 credited to the Participant during that Plan Year, including
                 those hours credited prior to the date the Employee enrolls
                 (or re-enrolls) as an Active Participant in the Plan, shall be
                 counted.

                 For purposes of the Contribution Computation Period, if any
                 Plan Year is less than 12 consecutive months, the number of
                 Hours of Service required to accrue a Year of Service, in such
                 short Plan Year, shall bear the same ratio to 1000 as the
                 number of days in the short Plan Year bears to 365.

2.7      EXCLUDED YEARS OF SERVICE. In determining the Vesting Percentage of an
         Employee, all Years of Service with the Employer shall be taken into
         account except:

         o       Plan Years during which a Participant did not complete at
                 least 1,000 Hours of Service.

2.8      PREDECESSOR ORGANIZATION SERVICE. For purposes of this Article,
         Service with a predecessor organization of the Employer shall be
         treated as Service with the Employer in any case in which the Employer
         maintains the Plan of such predecessor organization.

                   ELIGIBILITY, ENROLLMENT AND PARTICIPATION



3.1      ELIGIBILITY. Each Employee who was a Participant prior to the
         Effective Date and who is in the Service of the Employer on the
         Effective Date shall continue as a Participant in the Plan. Each other
         Employee, including a Leased Employee, shall be eligible to become a
         Participant as of the Effective Date or the Entry Date when he first
         meets the following requirement(s):

         o       One Year of Service (as defined in section 2.6)

         o       Age 21

3.2      ENROLLMENT AND PARTICIPATION. Each eligible Employee may enroll as of
         his Entry Date by completing and delivering to the Administrator an
         enrollment form and, if applicable, a Salary Deferral Agreement. He
         will then become a Participant as of his Entry Date.

3.3      RE-EMPLOYED EMPLOYEE. In the case of an individual who ceases to be an
         Employee and is subsequently rehired as an Employee, the following
         provisions shall apply in determining his eligibility to again
         participate in the Plan:

         (A)     If the Employee had met the eligibility requirement(s)
                 specified in Section 3.1 prior to his separation from
                 employment, he shall become an Active Participant in the Plan
                 as of the date he is re-employed, after completing the
                 applicable form(s), in accordance with Section 3.2.

         (B)     If the Employee had not met the eligibility requirement(s)
                 specified in Section 3.1 prior to his separation from
                 employment, he shall be eligible to participate in the Plan on
                 the first Entry Date following his fulfillment of such
                 eligibility requirement(s).

         For purposes of this Subsection, all Years of Service with the
         Employer, including any Years of Service prior to any Breaks in
         Service, shall be taken into account.

                                   ARTICLE IV
                                 CONTRIBUTIONS



4.1      ELECTIVE DEFERRAL CONTRIBUTIONS. Each Active Participant may enter
         into a written Salary Deferral Agreement with the Employer in an
         amount equal to not less than 0% nor more than 20% of his Compensation
         for the Contribution Period. In consideration of such agreement, the
         Employer will make a contribution for each Contribution Period on
         behalf of the Participant in an amount equal to the total amount by
         which the Participant's Compensation from the Employer was deferred
         during the Contribution Period pursuant to the Salary Deferral
         Agreement then in effect. Elective Deferral Contributions shall be
         paid by the Employer to the Trust not less frequently than monthly,
         but in no event later than 90 days following the date the amounts were
         deferred.

         Salary Deferral Agreements shall be governed by the following
         provisions:

         (A)     Amounts contributed pursuant to a Salary Deferral Agreement
                 shall be 100% vested and non-forfeitable at all times.

         (B)     No Participant shall be permitted to have Elective Deferral
                 Contributions made under this Plan, or any other qualified
                 plan maintained by the Employer, during any taxable year, in
                 excess of the dollar limitation contained in section 402(g) of
                 the Code in effect at the beginning of the taxable year.

         (C)     Amounts contributed pursuant to a Salary Deferral Agreement,
                 which are not in excess of the limit described in Subsection
                 (B) above, shall be subject to the Limitations on Allocations
                 in accordance with Article V. Elective Deferral Contributions
                 that are in excess of the limit described in Subsection (B)
                 shall also be subject to the Limitations on Allocations in
                 accordance with Article V.

         (D)     A Salary Deferral Agreement may be changed by a Participant
                 four times during the Plan Year, on January 1, April 1, July 1
                 and October 1, by filing written notice thereof with the
                 Administrator. Such notice shall be effective, and the Salary
                 Deferral Agreement shall be changed on the date specified in
                 such notice or as soon as administratively possible, which
                 date must be at least 15 days after such notice is filed.

         (E)     Elective Deferral Contributions shall be subject to the Actual
                 Deferral Percentage Test limitations.

         (F)     Correction of Excess Contributions.

                 (1)      If the Employer determines prior to the end of the
                          Plan Year that the Actual Deferral Percentage Test
                          may not be satisfied, the Employer may take the
                          corrective action specified in Section 4.12 of the
                          Plan.

                 (2)      If, after the end of the Plan Year, the Employer
                          determines that the Plan will fail the Actual
                          Deferral Percentage Test, the Employer shall take the
                          corrective action specified in Section 4.14 or
                          Section 4.17 of the Plan, or a combination of such
                          corrective actions, in order to ensure that the Plan
                          does not fail the Actual Deferral Percentage Test for
                          the





                                       20
<PAGE>   23
         Plan Year being tested.

4.2      MATCHING CONTRIBUTIONS. The Employer shall make a Matching
         Contribution in an amount equal to $.50 for each $1.00 by which a
         Participant defers his Compensation pursuant to a Salary Deferral
         Agreement up to a maximum of 6% of his Compensation, subject to the
         Limitations on Allocations specified in Article V. The Matching
         Contribution shall be paid to the Trust not less frequently than
         quarterly. Matching Contributions shall be subject to the Actual
         Contribution Percentage Test. The Employer may designate at the time
         of contribution that all or a portion of such Matching Contributions
         be treated as Qualified Matching Contributions.

         If the Employer determines prior to the end of the Plan Year that the
         Actual Contribution Percentage Test may not be satisfied, the Employer
         may take the corrective action specified in Section 4.13 of the Plan.

         If, after the end of the Plan Year, the Employer determines that the
         Plan will fail the Actual Contribution Percentage Test, the Employer
         shall take the corrective action specified in Section 4.15 or Section
         4.17 of the Plan, or a combination of such corrective actions, in
         order to ensure that the Plan does not fail the Actual Contribution
         Percentage Test for the Plan Year being tested.

         Such Matching Contribution shall be allocated as of the last day of
         the Contribution Period for which such contribution is made to each
         Participant who:

         o       is an Active Participant as of the last day of the 
                 Contribution Period.

         Notwithstanding the above provision, an allocation will be made on
         behalf of a Participant who dies, retires, or becomes disabled during
         the Contribution Period.

4.3      NONELECTIVE CONTRIBUTIONS. The Employer may make a contribution under
         the Plan for any Plan Year of an amount that the Employer's Board of
         Directors shall determine by resolution. Such resolution shall either
         specify a fixed amount or specify a definite formula by which a fixed
         amount can be determined.

         The Employer may designate at the time of contribution that all or a
         portion of such Nonelective Contribution be treated as a Qualified
         Nonelective Contribution.

         Such Nonelective Contribution shall be allocated as of the last day of
         the Plan Year for which such contribution is made to each Participant
         who:

         o       has a Year of Service for contribution purposes, as defined 
                 in Article II.

         o       is an Active Participant as of the last day of the Plan Year.

         Notwithstanding the above provision, an allocation will be made on
         behalf of a Participant who dies, retires, or becomes disabled during
         the Plan Year.

         For each Plan Year the contribution shall be allocated to each
         Participant in the proportion that the Compensation paid to each
         Participant during the Plan Year bears to the Compensation paid to all
         such Participants, subject to the Limitations on Allocations specified
         in Article V.





                                       21
<PAGE>   24
         The contribution as described above, for any Plan Year, shall be paid
         to the Trust at the end of the Plan Year, or as soon as possible on or
         after the last day of such Plan Year, but in any event not later than
         the date which is prescribed by law for filing the Employer's income
         tax return, including any extension thereof.

4.4      FAIL-SAFE CONTRIBUTION. The Employer reserves the right to make a
         discretionary Nonelective Contribution to the Plan for any Plan Year,
         if the Employer determines that such a contribution is necessary to
         ensure that either the Actual Deferral Percentage Test or the Actual
         Contribution Percentage Test will be satisfied for that Plan Year.
         Such amount shall be designated by the Employer at the time of
         contribution as a Qualified Nonelective Contribution and shall be
         known as a Fail-Safe Contribution.

         The Fail-Safe Contribution shall be made on behalf of all eligible
         non-Highly Compensated Employees who are Participants and who are
         considered under the Actual Deferral Percentage Test or the Actual
         Contribution Percentage Test. This contribution shall be allocated to
         the Participant's Account of each such Participant in an amount equal
         to a fixed percentage of such Participant's Compensation. The fixed
         percentage shall be equal to the minimum fixed percentage necessary to
         be contributed by the Employer on behalf of each eligible non-Highly
         Compensated Employee who is a Participant so that the Actual Deferral
         Percentage Test or the Actual Contribution Percentage Test is
         satisfied.

         The Fail-Safe Contribution for any Plan Year as determined above shall
         be paid to the Trust at the end of the Plan Year, or as soon as
         possible on or after the last day of such Plan Year, but in no event
         later than the date which is prescribed by law for filing the
         Employer's income tax return, including any extensions thereof.

4.5      PROFITS NOT REQUIRED. Contributions to this Plan shall not be
         precluded because the Employer does not have Considered Net Profits.
         Notwithstanding the existence of Considered Net Profits, the Employer
         may determine in its sole discretion that it will make no
         contributions for such Plan Year.

4.6      PAYMENT OF EXPENSES. The Employer may contribute to the Plan the
         amount necessary, to pay any applicable expense charges and
         administration charges. In lieu of the Employer's contributing the
         amount necessary to pay such charges, these expenses may be paid from
         the Trust fund.

4.7      ALLOCATION OF FORFEITURES. The contributions made by the Employer
         shall be reduced by any Forfeitures available as an Employer credit in
         accordance with Section 9.3.

4.8      CREDITING OF ELECTIVE DEFERRAL AND OTHER CONTRIBUTIONS. Elective
         Deferral Contributions and other contributions made by the Employer
         shall be credited to the Participant Account of each Participant for
         whom such contributions are made, in accordance with the provisions of
         Article XIII.

4.9      ROLLOVER CONTRIBUTIONS. The Plan may receive Rollover Contributions on
         behalf of an Employee. Receipt of a Rollover Contribution shall be
         subject to the approval of the Plan Administrator. Before approving
         the receipt of a Rollover Contribution, the Plan Administrator may
         request any documents or other information from an Employee or
         opinions of counsel which the Plan Administrator deems necessary to
         establish that such amount is a Rollover Contribution.

         A Participant's Account shall be maintained on behalf of each Employee
         from whom Rollover Contributions are received, regardless of such
         Employee's eligibility to participate in the Plan in accordance with
         the requirements of Article III, and Rollover Contributions may be
         invested in any manner authorized under the provisions of this Plan.





                                       22
<PAGE>   25
         Rollover Contributions received from an Employee who is not otherwise
         eligible to participate in the Plan may not be withdrawn in accordance
         with the provisions of Article X until such Employee becomes a
         Participant, except that such Employee may receive a distribution of
         his Participant's Account if his Termination of Employment occurs.

         Rollover Contributions shall be credited to the Participant's Account
         and may be invested in any manner authorized under the provisions of
         this Plan.

4.10     TRANSFERS. Without regard to the Limitations on Allocations imposed
         under Article V, the Trustee may receive, directly from another
         qualified pension or profit-sharing plan meeting the requirements of
         Internal Revenue Code section 401(a), all or part of the entire amount
         distributable on behalf of a Participant from such plan.  Likewise,
         the Trustee may receive Transfers representing the assets of any
         predecessor plan.

         Transfers may be invested in any manner authorized under the 
         provisions of this Plan.

4.11     SUSPENSION OF ELECTIVE DEFERRAL CONTRIBUTIONS. The following
         provisions shall apply with respect to suspension of Elective Deferral
         Contributions.

         (A)     Elective Suspension. An Active Participant may elect to
                 suspend his Salary Deferral Agreement for Elective Deferral
                 Contributions by filing a written notice thereof with the
                 Administrator at any time.  The Salary Deferral Agreement
                 shall be suspended on the date specified in such notice, which
                 date must be at least 15 days after such notice is filed. The
                 notice shall specify the period for which such suspension
                 shall be effective. Such period must be a minimum of three
                 months and may extend indefinitely.

         (B)     Suspension for Leave. A Participant who is absent from
                 employment on account of an authorized leave of absence or
                 military leave shall have his Salary Deferral Agreement
                 suspended during such leave. Such suspension of contributions
                 shall be effective on the date payment of Compensation by the
                 Employer to him ceases, and shall remain in effect until
                 payment of Compensation is resumed.

         (C)     Withdrawal Suspension. An Active Participant who elects a
                 withdrawal in accordance with Article X may have his Salary
                 Deferral Agreement suspended on the date such election becomes
                 effective. Such suspension shall remain in effect for the
                 number of months specified therein.

         The Participant may elect to reactivate his Salary Deferral Agreement
         for Elective Deferral Contributions  by filing a written notice
         thereof with the Plan Administrator. The Salary Deferral Agreement
         shall be reactivated on the January 1, April 1, July 1 and October 1
         following the expiration of the suspension period described above.

4.12     LIMITATION OF ELECTIVE DEFERRAL CONTRIBUTIONS. If the Employer
         determines prior to the end of the Plan Year that the Plan may not
         satisfy the Actual Deferral Percentage Test for the Plan Year, the
         Employer may require that the amount of Elective Deferral
         Contributions being allocated to the accounts of Highly Compensated
         Employees be reduced to the extent necessary to prevent Excess
         Contributions from being made to the Plan.

         Although the Employer may reduce the amount of Elective Deferral
         Contributions that may be allocated to the Participant's Account of
         Highly Compensated Employees, the affected Employees shall continue to
         participate in the Plan. When the situation that resulted in the
         reduction of Elective Deferral Contributions ceases to exist, the
         Employer shall reinstate the amount of Elective Deferral Contributions
         elected by the Participant in the Salary Deferral Agreement to the
         fullest extent possible for all affected Participants in





                                       23
<PAGE>   26
         a nondiscriminatory manner.

4.13     LIMITATION OF MATCHING CONTRIBUTIONS. If the Employer determines prior
         to the end of the Plan Year that the Plan may not satisfy the Actual
         Contribution Percentage Test for the Plan Year, the Employer may
         require that the amount of Matching Contributions being allocated to
         the Accounts of Highly Compensated Employees be reduced to the extent
         necessary to prevent Excess Aggregate Contributions from being made to
         the Plan.

4.14     CORRECTIVE DISTRIBUTION OF EXCESS CONTRIBUTIONS.

         (A)     The Employer may distribute Excess Contributions (and income
                 allocable thereto) to the appropriate Highly Compensated
                 Employee after the close of the Plan Year in which the Excess
                 Contribution arose and within 12 months after the close of
                 that Plan Year.

         (B)     The income allocable to Excess Contributions is equal to the
                 sum of the allocable gain or loss for the Plan Year and shall
                 be determined as follows:

                 (1)      The income allocable to Excess Contributions is
                          determined by multiplying the income for the Plan
                          Year allocable to Deferral Percentage Amounts by a
                          fraction. The numerator of the fraction is the Excess
                          Contributions attributable to the Employee for the
                          Plan Year. The denominator of the fraction is equal
                          to the sum of (A) the total account balance of the
                          Employee attributable to Deferral Percentage Amounts
                          as of the beginning of the Plan Year, plus (B) the
                          Employee's Deferral Percentage Amounts for the Plan
                          Year.

                 (2)      The allocable gain or loss for the period between the
                          end of the Plan Year and the date of distribution
                          shall not be taken into consideration when
                          determining the income allocable to Excess
                          Contributions.

         (C)     The amount of Excess Contributions to be distributed with
                 respect to an Employee for a Plan Year shall be reduced by
                 Excess Deferrals previously distributed to the Employee for
                 the Employee's taxable year ending with or within the Plan
                 Year.

         (D)     The distribution of Excess Contributions made to the Family
                 Members of a family group that was combined for purposes of
                 determining a Highly Compensated Employee's Actual Deferral
                 Ratio shall be allocated among the Family Members in
                 proportion to the Elective Deferral Contribution (including
                 any amounts required to be taken into account under
                 subparagraphs (B) (1) and (B) (2) of Section 1.8 of the Plan)
                 of each Family Member that is combined to determine the Actual
                 Deferral Ratio.

         (E)     A corrective distribution of Excess Contributions (and income)
                 shall be made without regard to any Participant or spousal
                 consent or any notice otherwise required under sections
                 411(a)(11) and 417 of the Code.

         (F)     Any Matching Contributions or Qualified Matching Contributions
                 that relate to the Excess Contribution being distributed shall
                 be forfeited. The Matching Contribution so forfeited shall be
                 in proportion to the applicable Employee's vested and
                 nonvested interest in Matching Contributions under the Plan
                 for the Plan Year in which the Excess Contribution arose.
                 Forfeitures of Matching Contributions or Qualified Matching
                 Contributions that relate to Excess Contributions shall be
                 applied to reduce Employer contributions or pay Plan expenses.

         (G)     In no case may the amount of Excess Contributions to be
                 distributed for a Plan Year with respect to any Highly 
                 Compensated Employee exceed the amount of Elective Deferral 
                 Contributions made on behalf of the Highly Compensated 
                 Employee for the Plan Year.




                                       24
<PAGE>   27
                 

         (H)     In the event of a complete termination of the Plan during the
                 Plan Year in which an Excess Contribution arose, the
                 corrective distribution must be made as soon as
                 administratively feasible after the date of the termination of
                 the Plan, but in no event later than 12 months after the date
                 of termination.

         (I)     Any distribution of less than the entire amount of Excess
                 Contributions with respect to any Highly Compensated Employee
                 shall be treated as a pro-rata distribution of Excess
                 Contributions and allocable income or loss.

4.15     CORRECTION OF EXCESS AGGREGATE CONTRIBUTIONS.

         (A)     Excess Aggregate Contributions may be corrected using one of
                 the methods described in subparagraphs (1) and (2) below. The
                 Employer shall elect the method of correction to be used and
                 shall apply such method to the correction of the Excess Annual
                 Contribution for the Plan Year.

                 (1)      Method 1:

                          (a)     The Excess Aggregate Contribution (and
                                  income) shall be forfeited, if forfeitable,
                                  or distributed on a pro-rata basis from the
                                  Employee's Account attributable to
                                  Contribution Percentage Amounts. The
                                  distribution or forfeiture shall be made
                                  after the close of the Plan Year in which the
                                  Excess Aggregate Contribution arose and
                                  within 12 months after the close of that Plan
                                  Year. Whether an amount is distributed or
                                  forfeited under this subparagraph (a) shall
                                  be determined based on the rules set forth in
                                  paragraph (B) of this section.

                 (2)      Method 2:

                          (a)     Any Matching Contributions (and Qualified
                                  Matching Contributions, to the extent not
                                  taken into account for purposes of the Actual
                                  Deferral Percentage Test), and income
                                  allocable thereto, shall be forfeited, if
                                  forfeitable, or distributed to the
                                  appropriate Highly Compensated Employee. The
                                  distribution or forfeiture shall be made
                                  after the close of the Plan Year in which the
                                  Excess Aggregate Contribution arose and
                                  within 12 months after the close of that Plan
                                  Year. Whether an amount is forfeited or
                                  distributed shall be determined under the
                                  rules set forth in paragraph (B) of this
                                  section.

         (B)     Determination of Distributable and Forfeitable Amounts. For
                 purposes of paragraph (A) of this section:

                 (1)      An Excess Aggregate Contribution attributable to
                          vested Matching Contributions, Qualified Matching
                          Contributions (and, if applicable, Qualified
                          Nonelective Contributions and Elective Deferral
                          Contributions) shall be distributed to the
                          appropriate Highly Compensated Employee in accordance
                          with the terms of this section.

                 (2)      An Excess Aggregate Contribution attributable to an
                          Employee's nonvested Matching Contributions shall be
                          forfeited in accordance with the terms of this
                          section.

                 (3)      A Highly Compensated Employee's vested and nonvested
                          interest in Matching





                                       25
<PAGE>   28
                          Contributions (and income allocable thereto) 
                          attributable to Excess Aggregate Contributions shall 
                          be based on the proportion that represents the 
                          Employee's Vested Interest in Matching Contributions
                          under the Plan for the Plan Year in which the Excess 
                          Aggregate Contribution arose.

         (C)     Forfeited Excess Aggregate Contributions. In accordance with
                 paragraph (B) of this section, the amount that represents the
                 Employee's nonvested interest in Matching Contributions (and
                 income), and is attributable to Excess Aggregate
                 Contributions, shall be forfeited and, as such, shall be
                 applied to reduce Employer contributions or pay expenses.

         (D)     Income Allocable to Excess Aggregate Contributions. For
                 purposes of this section, the income allocable to Excess
                 Aggregate Contributions is equal to the sum of the allocable
                 gain or loss for the Plan Year, and shall be determined as
                 follows:

                 (1)      The income allocable to Excess Aggregate
                          Contributions is determined by multiplying the income
                          for the Plan Year allocable to Contribution
                          Percentage Amounts by a fraction. The numerator of
                          the fraction is the Excess Aggregate Contributions
                          for the Employee for the Plan Year. The denominator
                          of the fraction is equal to the sum of (A) the total
                          account balance of the Employee attributable to
                          Contribution Percentage Amounts as of the beginning
                          of the Plan Year, plus (B) the Contribution
                          Percentage Amounts for the Plan Year.

                 (2)      The allocable gain or loss for the period between the
                          end of the Plan Year and the date of correction shall
                          not be taken into consideration when determining the
                          income allocable to Excess Aggregate Contributions.

         (E)     The distribution of Excess Aggregate Contributions (and
                 income) made to Family Members of a family group that was
                 combined for purposes of determining a Highly Compensated
                 Employee's Actual Contribution Ratio shall be allocated among
                 Family Members in proportion to the Contribution Percentage
                 Amounts (including any amounts required to be taken into
                 account under subparagraphs (B) (1) and (B) (2) of Section 1.5
                 of the Plan) of each Family Member that are combined to
                 determine the Actual Contribution Ratio.

         (F)     In the event of a complete termination of the Plan during the
                 Plan Year in which an Excess Aggregate Contribution arose, the
                 corrective distribution or forfeiture shall be made as soon as
                 administratively feasible after the date of termination of the
                 Plan, but in no event later than 12 months after the date of
                 termination.

         (G)     If the entire account balance of a Highly Compensated Employee
                 is distributed during the Plan Year in which the Excess
                 Aggregate Contribution arose, the distribution shall be deemed
                 to have been a corrective distribution of Excess Aggregate
                 Contributions (and income) to the extent that a corrective
                 distribution would otherwise have been required.

         (H)     Any distribution of less than the entire amount of Excess
                 Aggregate Contributions (and income) shall be treated as a
                 pro-rata distribution of Excess Aggregate Contributions and
                 allocable income or loss.

         (I)     In no case may the amount of Excess Aggregate Contributions
                 distributed to a Highly Compensated Employee exceed the amount
                 of Matching Contributions made on behalf of the Highly
                 Compensated Employee for the Plan Year.

         (J)     A distribution of Excess Aggregate Contributions (and income)
                 shall be made under this section without regard to any notice
                 or consent otherwise required under sections 411(a)(11) and
                 417 of the Code.

4.16     CORRECTIVE DISTRIBUTION OF EXCESS DEFERRALS. Notwithstanding any other
         provision of the Plan, Excess Deferrals, plus any income and minus any
         loss allocable thereto, may be distributed to any Participant to whose
         account Excess Deferrals were allocated for the individual's taxable
         year. Such a corrective distribution shall be made in accordance with
         this section.

         (A)     Correction of Excess Deferrals After Taxable Year.

                 (1)      Not later than the March 15 following the close of a
                          Participant's taxable year, the Participant may
                          notify the Plan of the amount of Excess Deferrals
                          received by the Plan during that taxable year. The
                          notification shall be in writing, shall specify the
                          Participant's Excess Deferrals, and shall be
                          accompanied by the Participant's written statement
                          that if such amounts are not distributed, these
                          amounts, when added to all other Elective Deferral
                          Contributions made on behalf of the Participant
                          during the taxable year, shall exceed the dollar
                          limitation specified in section 402(g) of the Code.

                 (2)      The Participant is deemed to have notified the Plan
                          of Excess Deferrals if, not later than the March 1
                          following the close of a Participant's taxable year,
                          the Employer notifies the Plan on behalf of the
                          Participant of the Excess Deferrals. Such Excess
                          Deferrals shall be calculated by taking into account
                          only Elective Deferral Contributions under the Plan
                          and any other plans of the Employer.

                 (3)      Not later than the April 15 following the close of
                          the taxable year, the Plan shall distribute to the
                          Participant the amount of Excess Deferrals designated
                          under subparagraphs (1) or (2) above.

         (B)     Correction of Excess Deferrals During the Taxable Year. A
                 Participant who has an Excess Deferral during a taxable year
                 may receive a corrective distribution during the same year.
                 Such a corrective distribution shall be made if:

                 (1)      The Participant designates the distribution as an
                          Excess Deferral. The designation shall be made in the
                          same manner as the notification described in
                          subparagraph (A) (1) of this section.  The
                          Participant will be deemed to have designated the
                          distribution as an Excess Deferral if the Employer
                          makes the designation on behalf of the Participant to
                          the extent that the Participant has Excess Deferrals
                          for the taxable year calculated by taking into
                          account only Elective Deferral Contributions to the
                          Plan and other plans of the Employer.

                 (2)      The corrective distribution is made after the date on
                          which the Plan received the Excess Deferral.

                 (3)      The Plan designates the distribution as a
                          distribution of Excess Deferrals.

         (C)     If the Participant provides the Employer with satisfactory
                 evidence and written notice to demonstrate that all Elective
                 Deferral Contributions by the participant in this Plan and any
                 other qualified plan exceed the applicable limit under section
                 402(g) of the Code for such individual's taxable year, then
                 the Plan Administrator may (but is not required to) distribute
                 sufficient Elective Deferral Contributions (not to exceed the
                 amount of Elective Deferral Contributions actually contributed
                 on behalf of the Participant to this Plan during the
                 Participant's taxable year) from this

                 Plan to allow the Participant to comply with the applicable 
                 limit. The evidence provided by the Participant must establish
                 clearly the amount of Excess Deferrals. The Participant must 
                 present this evidence to the Plan Administrator by the March 
                 1 following the end of the calendar year in which the Excess 
                 Deferrals occurred.

         (D)     Income Allocable to Excess Deferrals. The income allocable to
                 Excess Deferrals is equal to the sum of allocable gain or loss
                 for the taxable year of the individual and shall be determined
                 as follows:

                 (1)      The gain or loss allocable to Excess Deferrals is
                          determined by multiplying the income for the taxable
                          year allocable to Elective Deferral Contributions by
                          a fraction. The numerator of the fraction is the
                          Excess Deferrals by the Employee for the taxable
                          year. The denominator of the fraction is equal to the
                          sum of:

                          (a)     The total account balance of the Employee
                                  attributable to Elective Deferral
                                  Contributions as of the beginning of the Plan
                                  Year, plus

                          (b)     The Employee's Elective Deferral 
                                  Contributions for the taxable year.

                 (2)      The income allocable to Excess Deferrals shall not
                          include the allocable gain or loss for the period
                          between the end of the taxable year and the date of
                          distribution.

         (E)     No Employee or Spousal Consent Required. A corrective
                 distribution of Excess Deferrals (and income) shall be made
                 without regard to any notice or consent otherwise required
                 under sections 411(a)(11) and 417 of the Code.

         (F)     Any Matching Contributions or Qualified Matching Contributions
                 that relate to the Excess Deferral being distributed shall be
                 forfeited. The Matching Contribution so forfeited shall be in
                 proportion to the applicable Employee's vested and nonvested
                 interest in Matching Contributions under the Plan for the Plan
                 Year in which the Excess Deferral arose. Forfeitures of
                 Matching Contributions or Qualified Matching Contributions
                 that relate to Excess Deferrals shall be applied to reduce
                 Employer contributions or pay Plan expenses.

4.17     QUALIFIED CONTRIBUTIONS. In lieu of distributing Excess Contributions
         as provided in Section 4.14 of the Plan, or Excess Aggregate
         Contributions as provided in Section 4.15 of the Plan, the Employer
         may take the actions specified below in order to satisfy the Actual
         Deferral Percentage Test or the Actual Contribution Percentage Test,
         or both, pursuant to the regulations under the Code.

         (A)     At the election of the Employer, Qualified Nonelective
                 Contributions or Qualified Matching Contributions, or both,
                 may be taken into account as Elective Deferral Contributions
                 for purposes of calculating the Actual Deferral Ratio of a
                 Participant.

                 The amount of Qualified Nonelective Contributions or Qualified
                 Matching Contributions made under the terms of this Plan and
                 taken into account as Elective Deferral Contributions for
                 purposes of calculating the Actual Deferral Ratio, subject to
                 such other requirements as may be prescribed by the Secretary
                 of the Treasury, shall be such Qualified Nonelective
                 Contributions or Qualified Matching Contributions, or both,
                 that are needed to meet the Actual Deferral Percentage Test.

         (B)     At the election of the Employer, Qualified Nonelective
                 Contributions or Elective Deferral Contributions, or both, may
                 be taken into account as Matching Contributions for purposes
                 of calculating the Actual Contribution Ratio of a Participant.





                                       28
<PAGE>   31
                 The amount of Qualified Nonelective Contributions or Elective
                 Deferral Contributions made under the terms of this Plan and
                 taken into account for purposes of calculating the Actual
                 Contribution Ratio, subject to such other requirements as may
                 be prescribed by the Secretary of the Treasury, shall be such
                 Qualified Nonelective Contributions or Elective Deferral
                 Contributions, or both, that are needed to meet the Actual
                 Contribution Percentage Test.

         (C)     Any Qualified Nonelective Contribution, Qualified Matching
                 Contribution, and Elective Deferral Contribution taken into
                 account under paragraphs (A) or (B) must be allocated to the
                 Employee's Account as of a date within the Plan Year in which
                 the Excess Contribution or Excess Aggregate Contribution arose
                 and must be paid to the Plan no later than the 12-month period
                 immediately following the Plan Year to which the contribution
                 relates.

4.18     MULTIPLE USE OF ALTERNATIVE LIMITATION.

         (A)     Multiple use of the alternative limitation occurs if all of
                 the conditions of this paragraph (A) are satisfied:

                 (1)      One or more Highly Compensated Employee of the
                          Employer are eligible employees in both a cash or
                          deferred arrangement subject to section 401(k) and a
                          plan maintained by the Employer subject to section
                          401(m).

                 (2)      The sum of the Actual Deferral Percentage of the
                          entire group of eligible Highly Compensated Employees
                          under the arrangement subject to section 401(k) and
                          the Actual Contribution Percentage of the entire
                          group of eligible Highly Compensated Employees under
                          the Plan subject to section 401(m) exceeds the
                          aggregate limit of paragraph (C) of this section.

                 (3)      Actual Deferral Percentage of the entire group of
                          eligible Highly Compensated Employees under the
                          arrangement subject to section 401(k) exceeds the
                          amount described in section 401(k)(3)(A)(ii)(I).

                 (4)      The Actual Contribution Percentage of the entire
                          group of eligible Highly Compensated Employees under
                          the arrangement subject to section 401(m) exceeds the
                          amount described in section 401(m)(2)(A)(i).

         (B)     For purposes of this section, the aggregate limit is the
                 greater of:

                 (1)      The sum of-

                          (a)     1.25 times the greater of the relevant Actual
                                  Deferral Percentage or the relevant Actual
                                  Contribution Percentage, and

                          (b)     Two percentage points plus the lesser of the
                                  relevant Actual Deferral Percentage or the
                                  relevant Actual Contribution Percentage. In
                                  no event, however, may this amount exceed
                                  twice the lesser of the relevant Actual
                                  Deferral Percentage or the Actual
                                  Contribution Percentage; or

                 (2)      The sum of-

                          (a)     1.25 times the lesser of the relevant Actual
                                  Deferral Percentage or the relevant Actual
                                  Contribution Percentage, and





                                       29
<PAGE>   32
                          (b)     Two percentage points plus the greater of the
                                  relevant Actual Deferral Percentage or the
                                  relevant Actual Contribution Percentage. In
                                  no event, however, may this amount exceed
                                  twice the greater of the relevant Actual
                                  Deferral Percentage or the relevant Actual
                                  Contribution Percentage.

         (C)     For purposes of paragraph (B) of this section, the term
                 "relevant Actual Deferral Percentage" means the Actual
                 Deferral Percentage of the group of Nonhighly Compensated
                 Employees under the arrangement subject to section 401(k) for
                 the Plan Year, and the term "relevant Actual Contribution
                 Percentage" means the Actual Contribution Percentage of the
                 group of Nonhighly Compensated Employees eligible under the
                 Plan subject to section 401(m) for the Plan Year beginning
                 with or within the Plan Year of the arrangement subject to
                 section 401(k).

         (D)     The Actual Deferral Percentage and Actual Contribution
                 Percentage of the group of eligible Highly Compensated
                 Employees are determined after use of Qualified Nonelective
                 Contributions and Qualified Matching Contributions to meet the
                 requirements of the Actual Deferral Percentage Test and after
                 use of Qualified Nonelective Contributions and Elective
                 Deferral Contributions to meet the requirements of the Actual
                 Contribution Percentage Test. The Actual Deferral Percentage
                 and Actual Contribution Percentage of the group of Highly
                 Compensated Employees are determined after any corrective
                 distribution or forfeiture of Excess Deferrals, Excess
                 Contributions, or Excess Aggregate Contributions and after
                 recharacterization of Excess Contributions required without
                 regard to this section. Only plans and arrangements maintained
                 by the Employer are taken into account under paragraph (B). If
                 the Employer maintains two or more cash or deferred
                 arrangements subject to section 401(k) that must be
                 mandatorily disaggregated pursuant to section
                 401(k)-1(g)(11)(iii) multiple use is tested separately with
                 respect to each plan.

         (E)     If multiple use of the alternative limit occurs with respect
                 to two or more plans or arrangements maintained by the
                 Employer, it shall be corrected by reducing the Actual
                 Contribution Percentage of Highly Compensated Employees in the
                 manner described in paragraph (F) of this section. Instead of
                 making this reduction, the Employer may eliminate the multiple
                 use of the alternative limitation by making Qualified
                 Nonelective Contributions to the Plan.

         (F)     The amount of the reduction by which each Highly Compensated
                 Employee's Actual Contribution Ratio is reduced shall be
                 treated as an Excess Aggregate Contribution. The Actual
                 Contribution Percentage of all Highly Compensated Employees
                 under the plan subject to reduction shall be reduced so that
                 there is no multiple use of the alternative limitation.

                           LIMITATIONS ON ALLOCATIONS



5.1      LIMITATIONS ON ALLOCATIONS. Definitions - The following definitions
         are atypical terms which refer only to terms used in the Limitations
         on Allocations Sections of this Article V.

         (A)     Annual Additions. The term Annual Additions shall mean the sum
                 of the following amounts allocated on behalf of a Participant
                 for a Limitation Year:

                (1)      all contributions made by the Employer which shall 
                         include:

                         o       Elective Deferral Contributions, if any;

                         o       Matching Contributions, if any;

                         o       Qualified Matching Contributions, if any;

                         o       Nonelective Contributions, if any;

                         o       Qualified Nonelective Contributions, if any;

                 (2)      all Forfeitures, if any;

                 (3)      all Employee Contributions, if any.

                 For the purposes of this Article, Excess Amounts reapplied
                 under Section 5.2 (D) shall also be included as Annual
                 Additions. Also, for the purposes of this Article, Employee
                 Contributions are determined without regard to deductible
                 employee contributions within the meaning of section 72(o)(5)
                 of the Code.


                 Amounts allocated after March 31, 1984, to an individual
                 medical account, as defined in Internal Revenue Code section
                 415(l)(1), which is part of a defined benefit plan maintained
                 by the Employer, are treated as Annual Additions to a defined
                 contribution plan. Also, amounts derived from contributions
                 paid or accrued attributable to post-retirement medical
                 benefits allocated to the separate account of a key employee,
                 as defined in Internal Revenue Code section 419A(d)(3), under
                 a welfare benefit fund, as defined in Internal Revenue Code
                 section 419(e), maintained by the Employer, are treated as
                 Annual Additions to a defined contribution plan.

                 Contributions do not fail to be Annual Additions merely
                 because they are Excess Deferrals, Excess Contributions or
                 Excess Aggregate Contributions or merely because Excess
                 Contributions or Excess Aggregate Contributions are corrected
                 through distribution or recharacterization. Excess Deferrals
                 that are distributed in accordance with Section 4.16 of the
                 Plan are not Annual Additions.

                 Forfeited Matching Contributions that are forfeited because
                 the contributions to which they relate are treated as Excess
                 Aggregate Contributions, Excess Contributions, or Excess
                 Deferrals and that are reallocated to the Participant Accounts
                 of other Participants for the Plan Year in which the
                 forfeiture occurs, are treated as Annual Additions for the
                 Participants to whose accounts they are





                                       31
<PAGE>   34
                 reallocated and for the Participants from whose accounts they 
                 are forfeited.

         (B)     Compensation. The term Compensation means wages within the
                 meaning of section 3401(a) of the Code for the purposes of
                 income tax withholding at the source but determined without
                 regard to any rules that limit the remuneration included in
                 wages based on the nature or location of the employment or the
                 services performed (such as the exception for agricultural
                 labor in section 3401(a)(2) of the Code).

                 For Limitation Years beginning after December 31, 1991, for
                 purposes of applying the limitations of this article,
                 Compensation for a Limitation Year is the Compensation
                 actually paid or made available during such Limitation Year.

         (C)     Defined Contribution Dollar Limitation. The term Defined
                 Contribution Dollar Limitation shall mean $30,000 or, if
                 greater, one-fourth of the defined benefit dollar limitation
                 set forth in Internal Revenue Code section 415(b)(1) as in
                 effect for the Limitation Year.

         (D)     Employer. The term Employer shall mean the Employer that
                 adopts this Plan. In the case of a group of employers which
                 constitutes a controlled group of corporations (as defined in
                 Internal Revenue Code section 414(b) as modified by section
                 415(h)), or which constitutes trades or business (whether or
                 not incorporated) which are under common control (as defined
                 in section 414(c) as modified by section 415(h)), or
                 affiliated service groups (as defined in section 414(m)) of
                 which the adopting Employer is a part, all such employers
                 shall be considered a single Employer for purposes of applying
                 the limitations of this Article.

         (E)     Excess Amount. The term Excess Amount shall mean the excess of
                 the Participant's Annual Additions for the Limitation Year
                 over the Maximum Permissible Amount.

         (F)     Limitation Year. The term Limitation Year shall mean the 
                 calendar year.

         (G)     Maximum Permissible Amount. The term Maximum Permissible
                 Amount shall mean the lesser of (1) the Defined Contribution
                 Dollar Limitation, or (2) 25% of the Participant's
                 Compensation for the Limitation Year.

                 If a short Limitation Year is created because of an amendment
                 changing the Limitation Year to a different period of 12
                 consecutive months, the Maximum Permissible Amount for the
                 short Limitation Year will be the lesser of (1) the Defined
                 Contribution Dollar Limitation 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, or (2)
                 25% of the Participant's Compensation for the short Limitation
                 Year.

5.2      LIMITATIONS ON ALLOCATIONS. If the Employer does not maintain any
         qualified plan in addition to this Plan:

         (A)     The amount of Annual Additions which may be allocated under
                 this Plan on a Participant's behalf for a Limitation Year
                 shall not exceed the lesser of the Maximum Permissible Amount
                 or any other limitation contained in this Plan.

         (B)     Prior to the determination of the Participant's actual
                 Compensation for a Limitation Year, the Maximum Permissible
                 Amount may be determined on the basis of the Participant's
                 estimated annual Compensation.  Such Compensation shall be
                 determined on a reasonable basis and shall be uniformly
                 determined for all Participants similarly situated. Any
                 employer contributions based on





                                       32
<PAGE>   35
                 estimated annual Compensation shall be reduced by any Excess 
                 Amounts carried over from prior years.

         (C)     As soon as is administratively feasible after the end of the
                 Limitation Year, the Maximum Permissible Amount for such
                 Limitation Year shall be determined on the basis of the
                 Participant's actual Compensation for such Limitation Year. In
                 the event a Participant separates from the Service of the
                 Employer prior to the end of the Limitation Year, the Maximum
                 Permissible Amount for such Participant shall be determined
                 prior to any distribution of his Participant's Account on the
                 basis of his actual Compensation. Any Excess Amounts shall be
                 disposed of in accordance with Section 5.2 (D).

         (D)     If there is an Excess Amount with respect to a Participant for
                 a Limitation Year as a result of a reasonable error in
                 estimating the Participant's annual compensation, an
                 allocation of forfeitures, a reasonable error in determining
                 the amount of elective deferrals (within the meaning of
                 section 402(g)(3) of the Code) that may be made with respect
                 to any individual under the limits of section 415 of the Code,
                 or under other limited facts and circumstances which the
                 commissioner finds justified, such Excess Amount shall be
                 disposed of as follows:

                 (1)      If an Excess Amount exists, the Excess Amount in the
                          Participant's Account (excluding Elective Deferral
                          Contributions) shall be held unallocated in a
                          suspense account for the Limitation Year and
                          allocated and reallocated in the next Limitation Year
                          to all Participants in the Plan. The excess amount
                          must be used to reduce Employer Contributions for the
                          next Limitation Year (and succeeding Limitation
                          Years, as necessary) for all of the Participants in
                          the Plan. For purposes of this subparagraph, the
                          Excess Amount may not be distributed to Participants
                          or former Participants.

                 (2)      If, after the application of subparagraph (1) an
                          Excess Amount still exists, then the Participant's
                          Elective Deferral Contributions (including earnings
                          and losses thereon) allocated for the Limitation Year
                          shall be returned to the Participant to the extent
                          that an Excess Amount exists. This distribution shall
                          be made as soon as administratively feasible after
                          the Excess Amount is determined. Any Elective
                          Deferral Contributions returned under this paragraph
                          shall be disregarded for purposes of the Actual
                          Deferral Percentage Test.

                 (3)      Alternatively, the Plan Administrator may elect to
                          dispose of the Excess Amount by applying the
                          procedure in subparagraph (2) before applying the
                          procedure in subparagraph (1). If the Plan
                          Administrator makes this election, the Plan
                          Administrator must apply it uniformly to all
                          Participants in a Limitation Year.

                 (4)      If a suspense account is in existence at any time
                          during a Limitation Year pursuant to this section, it
                          will not participate in the allocation of investment
                          gains or losses. If a suspense account is in
                          existence at any time during a particular Limitation
                          Year, all amounts in the suspense account must be
                          allocated and reallocated to Participants' Accounts
                          before any Employer Contributions which would
                          constitute Annual Additions may be made to the Plan
                          for that Limitation Year.

5.3      LIMITATIONS ON ALLOCATIONS. If the Employer maintains one or more
         defined contribution plans in addition to this Plan:

         (A)     The amount of Annual Additions which may be allocated under
                 this Plan on a Participant's behalf for a Limitation Year,
                 shall not exceed the lesser of:





                                       33
<PAGE>   36
                 (1)      The Maximum Permissible Amount, reduced by the sum of
                          any Annual Additions allocated to the Participant's
                          Account for the same Limitation Year under this Plan
                          and such other defined contribution plan; or

                 (2)      Any other limitation contained in this Plan.

                 Prior to the determination of the Participant's actual
                 Compensation for the Limitation Year, the amounts referred to
                 in Subsection (1) above may be determined on the basis of the
                 Participant's estimated annual Compensation for such
                 Limitation Year. Such estimated annual Compensation shall be
                 determined for all Participants similarly situated.

                 Any contribution made by the Employer based on estimated
                 annual Compensation shall be reduced by any Excess Amounts
                 carried over from prior years, if applicable.

         (B)     As soon as is administratively feasible after the end of the
                 Limitation Year, the amounts referred to in Section 5.3 (A)
                 shall be determined on the basis of the Participant's actual
                 Compensation for such Limitation Year.

         (C)     If amounts are contributed to a Participant's Account under
                 this Plan on an allocation date which does not coincide with
                 the allocation date(s) for all such other plans, and if a
                 Participant's Annual Additions under this Plan and all such
                 other plans result in an Excess Amount, such Excess Amount
                 shall be deemed to have derived from those contributions last
                 allocated.

         (D)     If an Excess Amount was allocated to a Participant on an
                 allocation date of this Plan which coincides with an
                 allocation date of another plan, the Excess Amount
                 attributable to this Plan will be the product of (1) and (2)
                 below:

                 (1)      The total Excess Amount allocated as of such date
                          (including any amount which would have been allocated
                          but for the limitations of Internal Revenue Code
                          section 415).

                 (2)      The ratio of (1) the amount allocated to the
                          Participant as of such date under this Plan, divided
                          by (2) the total amount allocated as of such date
                          under all qualified defined contribution plans
                          (determined without regard to the limitations of
                          Internal Revenue Code section 415).

         (E)     Any Excess Amounts attributed to this Plan shall be disposed
                 of as provided in Section 5.2 (D).

5.4      LIMITATIONS ON ALLOCATIONS. If the Employer maintains a defined
         benefit plan in addition to this Plan:

         (A)     If an individual is a Participant at any time in both this
                 Plan and a defined benefit plan maintained by the Employer,
                 the sum of the Defined Benefit Plan Fraction and the Defined
                 Contribution Plan Fraction for any year may not exceed 1.0. In
                 the event that the sum of the Defined Contribution Plan
                 Fraction and the Defined Benefit Plan Fraction exceeds 1.0,
                 the Defined Contribution Plan Fraction will be reduced until
                 the sum of the Defined Contribution Plan Fraction and the
                 Defined Benefit Plan Fraction does not exceed 1.0.

                 If an individual was a Participant in this Plan or in any
                 other defined contribution plan maintained by the Employer
                 which was in existence on July 1, 1982, the numerator of the
                 Defined Contribution Plan Fraction will be adjusted if the sum
                 of the Defined Contribution Plan Fraction and the Defined
                 Benefit Plan Fraction would otherwise exceed 1.0 under the
                 terms of this Plan.





                                       34
<PAGE>   37
                 Under the adjustment, an amount equal to the product of (1) 
                 the excess of the sum of the Fractions over 1.0 times (2) the 
                 denominator of the Defined Contribution Plan Fraction, will 
                 be permanently subtracted from the numerator of the Defined 
                 Contribution Plan Fraction. The adjustment is calculated 
                 using the Fractions as they would be computed as of the later 
                 of the end of the last Limitation Year beginning before 
                 January 1, 1983, or June 30, 1983. This adjustment also will 
                 be made if at the end of the last Limitation Year beginning 
                 before January 1, 1984, the sum of the Fractions exceeds 1.0 
                 because of accruals or additions that were made before the 
                 limitations of this Article became effective to any plans of 
                 the Employer in existence on July 1, 1982.

                 In addition, if an individual was a Participant in this Plan 
                 or in any other defined contribution plan maintained by the 
                 Employer which was in existence on May 6, 1986, the numerator 
                 of the Defined Contribution Plan Fraction will be adjusted if 
                 the Employer's defined benefit plan was also in existence on 
                 May 6, 1986, and the sum of the Defined Plan Fraction and the 
                 Defined Benefit Plan Fraction would otherwise exceed 1.0 
                 under the terms of this Plan. Under the adjustment, an amount 
                 equal to the product of (1) the excess of the sum of the 
                 Fractions over 1.0 times (2) the denominator of the Defined 
                 Contribution Plan Fraction, will be permanently subtracted from
                 the numerator of the Defined Contribution Plan Fraction. This 
                 adjustment is calculated using the Fractions as they would be 
                 computed as of the end of the last Limitation Year beginning 
                 before January 1, 1987. In the event that a Participant's 
                 accrued benefit as of December 31, 1986, under the defined 
                 benefit plan exceeds the defined benefit dollar limitation 
                 set forth in Internal Revenue Code section 415(b)(1), the 
                 amount of that accrued benefit shall be used in both the 
                 numerator and the denominator of the Defined Benefit Plan 
                 Fraction in making this adjustment.
         
                 For purposes of this Section 5.4, all defined benefit plans 
                 of the Employer, whether or not terminated, will be treated 
                 as one defined benefit plan and all defined contribution 
                 plans of the Employer, whether or not terminated, will be 
                 treated as one defined contribution plan.

         (B)     The Defined Benefit Plan Fraction for any year is a fraction,
                 the numerator of which is the Participant's Projected Annual
                 Benefit under the defined benefit plan (determined as of the
                 close of the Limitation Year), and the denominator of which is
                 the lesser of (1) or (2) below:

                 (1)      1.25 times the dollar limitation in effect under
                          Internal Revenue Code section 415(b)(1)(A) on the
                          last day of the Limitation Year; or

                 (2)      1.4 times the amount which may be taken into account
                          under Internal Revenue Code section 415(b)(1)(B) with
                          respect to such Participant for the Limitation Year.

                 Notwithstanding the above, if the Participant was a
                 participant in one or more defined benefit plans maintained by
                 the Employer which were in existence on July 1, 1982, the
                 denominator of the Defined Benefit Plan Fraction will not be
                 less than 125% of the sum of the annual benefits under such
                 plans which the Participant had accrued as of the later of the
                 end of the last Limitation Year beginning before January 1,
                 1983 or June 30, 1983. The preceding sentence applies only if
                 the defined benefit plans individually and in the aggregate
                 satisfied the requirements of Internal Revenue Code section
                 415 as in effect at the end of the 1982 Limitation Year.

         (C)     A Participant's Projected Annual Benefit is equal to the
                 annual benefit to which the Participant would be entitled
                 under the terms of the defined benefit plan based upon the
                 following assumptions:

                 (1)      The Participant will continue employment until
                          reaching Normal Retirement Age as determined under
                          the terms of the plan (or current age, if that is
                          later);





                                       35
<PAGE>   38
                 (2)      The Participant's Compensation for the Limitation
                          Year under consideration will remain the same until
                          the date the Participant attains the age described in
                          sub-division (1) of this subparagraph; and

                 (3)      All other relevant factors used to determine benefits
                          under the plan for the Limitation Year under
                          consideration will remain constant for all future
                          Limitation Years.

         (D)     The Defined Contribution Plan Fraction for any Limitation Year
                 is a fraction, the numerator of which is the sum of the Annual
                 Additions to the Participant's Accounts in such Limitation
                 Year and for all prior Limitation Years, and the denominator
                 of which is the lesser of (1) or (2) below for such Limitation
                 Year and for all prior Limitation Years of such Participant's
                 employment (assuming for this purpose, that Internal Revenue
                 Code section 415(c) had been in effect during such prior
                 Limitation Years):

                 (1)      1.25 times the dollar limitation in effect under
                          Internal Revenue Code section 415(c)(1)(A) on the
                          last day of the Limitation Year; or

                 (2)      1.4 times the amount which may be taken into account
                          under Internal Revenue Code section 415(c)(1)(B) with
                          respect to such Participant for the Limitation Year.

                 For the purposes of determining these Limitations on
                 Allocations, any non-deductible employee contributions made
                 under a defined benefit plan will be considered to be a
                 separate defined contribution plan and will be considered to
                 be part of the Annual Additions for the appropriate Limitation
                 Year.

                 Annual Additions for any Limitation Year beginning before
                 January 1, 1987, shall not be recomputed to treat all Employee
                 Contributions as Annual Additions.

         (E)     Notwithstanding the foregoing, at the election of the Plan
                 Administrator, in computing the Defined Contribution Plan
                 Fraction with respect to any Plan Year ending after December
                 31, 1982, the denominator shall be an amount equal to the
                 product of:

                 (1)      The denominator of the Defined Contribution Plan
                          Fraction, computed in accordance with the rules in
                          effect for the Plan Year ending in 1982; and

                 (2)      the transition fraction, which is a fraction

                          (a)     the numerator of which is the lesser of:

                                  (i)      $51,875, or

                                  (ii)     1.4 times 25% of the Compensation of
                                           the Participant for the Plan Year
                                           ending in 1981, and

                          (b)     the denominator of which is the lesser of:

                                  (i)      $41,500, or

                                  (ii)     25% of the Compensation of the 
                                           Participant for the Plan Year ending
                                           in 1981.

                                   ARTICLE VI
                            DISTRIBUTION OF BENEFITS



6.1      DISTRIBUTIONS IN GENERAL. Each Participant may elect, with his
         Spouse's consent if required, a distribution in the form of an
         Annuity, a single sum cash payment, Employer stock, or a combination
         of the above. All distributions are subject to the provisions of
         Article VIII, Joint and Survivor Annuity Requirements.

         Distributions of Employer stock are limited to the value of the
         Participant's Employer Stock Account and shall be made by the Trustee.

6.2      TIMING OF DISTRIBUTIONS. If the value of a Participant's Vested
         Interest exceeds (or at the time of any prior distribution exceeded)
         $3,500 and is immediately distributable (as defined in Section 8.5),
         the Participant and his Spouse, if required, must consent to the
         distribution before it is made.

         Instead of consenting to a distribution, the Participant may make a
         written election to defer the distribution for a specified period of
         time ending no later than the Participant's Normal Retirement Age.
         Such election to defer shall be irrevocable.

         If the Participant and Spouse, if applicable, do not consent to a
         distribution or if no election to defer is made within 90 days after
         receiving a written explanation of the optional forms of benefit
         available pursuant to Income Tax Regulation 1.411(a)(11), all benefits
         shall be deferred to, and distribution shall be made as of the
         Participant's Normal Retirement Age. The distribution will be made in
         the form of a single sum cash payment (in the case of a Participant's
         meeting the requirements of Section 8.1 (A)) or in accordance with
         Section 8.2 (in the case of a Participant's not meeting the
         requirements of Section 8.1 (A)), unless the Participant elects
         another form of benefit within the 90-day period prior to the date the
         distribution is made.

         A Participant whose actual retirement date is on or after his Normal
         Retirement Age may not elect to defer distribution of his benefit
         beyond the date of his actual retirement.

         If the value of a Participant's Vested Interest is $3,500 or less at
         the time it becomes payable, the distribution shall be made in the
         form of a single sum cash payment and shall be made upon such
         Participant's Termination of Employment. Such a distribution may not
         be deferred.

         Unless the Participant elects otherwise, the payment of benefits under
         this Plan to the Participant shall begin not later than the 60th day
         after the close of the Plan Year in which the later of (A) or (B),
         below, occurs:

         (A)     the date on which the Participant attains his Normal
                 Retirement Age or age 62, if later; or

         (B)     the date on which the Participant terminates his Service
                 (including Termination of Employment, death or Disability)
                 with the Employer.

         Notwithstanding the foregoing, the failure of a Participant and
         Spouse, if required, to consent to a distribution while a benefit is
         immediately distributable shall be deemed to be an election to defer
         commencement of payment of any benefit sufficient to satisfy the above
         paragraph.

6.3      DISTRIBUTION LIMITATION. Elective Deferral Contributions, Qualified
         Nonelective Contributions and Qualified Matching Contributions, and
         income allocable to each, are not distributable to a Participant or a
         Beneficiary, in accordance with such Participant's or Beneficiary's
         election, earlier than upon the Participant's Termination of
         Employment, death, or disability.

         Such amounts may also be distributed upon:

         (A)     Termination of the Plan without the establishment or
                 maintenance of a successor plan.

                 For purposes of this paragraph, a successor plan is any other
                 defined contribution plan maintained by the same employer.
                 However, if fewer than two percent of the Employees who are
                 eligible under the Plan at the time of its termination are or
                 were eligible under another defined contribution plan at any
                 time during the 24 month period beginning 12 months before the
                 time of the termination, the other plan is not a successor
                 plan. The term "defined contribution plan" means a plan that
                 is a defined contribution plan as defined in section 414(i) of
                 the Code, but does not include an employee stock ownership
                 plan as defined in section 4975(e) or 409 of the Code or a
                 simplified employee pension as defined in section 408(k) of
                 the Code. A plan is a successor plan only if it exists at the
                 time the Plan is terminated or within the period ending 12
                 months after distribution of all assets from the Plan.

                 A distribution may be made under this paragraph only if it is
                 a lump sum distribution. The term "lump sum distribution" has
                 the same meaning provided in section 402(e)(4) of the Code,
                 without regard to subparagraphs (A)(i) through (iv), (B), and
                 (H) of that section.

         (B)     The disposition by the Employer to an unrelated corporation of
                 substantially all the assets (within the meaning of section
                 409(b)(2) of the Code) used in the trade or business of the
                 Employer if the Employer continues to maintain this Plan after
                 the disposition. However, a distribution may be made under
                 this paragraph only to an Employee who continues employment
                 with the corporation acquiring such assets.

                 In addition, this requirement is satisfied only if the
                 purchaser does not maintain the Plan after the disposition. A
                 purchaser maintains the plan of the seller if it adopts the
                 plan or otherwise becomes an employer whose employees accrue
                 benefits under the Plan. A purchaser also maintains the Plan
                 if the Plan is merged or consolidated with, or any assets or
                 liabilities are transferred from the Plan to a plan maintained
                 by the purchaser in a transaction subject to section 414(l)(1)
                 of the Code. A purchaser is not treated as maintaining the
                 Plan merely because the Plan that it maintains accepts
                 rollover contributions of amounts distributed by the Plan.

                 For purposes of this paragraph, the sale of "substantially
                 all" the assets used in a trade or business means the sale of
                 at least 85 percent of the assets.

                 A distribution may be made under this paragraph only if it is
                 a lump sum distribution. The term "lump sum distribution" has
                 the same meaning provided in section 402(e)(4) of the Code,
                 without regard to subparagraphs (A)(i) through (iv), (B), and
                 (H) of that section.

         (C)     The disposition by the Employer to an unrelated entity or
                 individual of the Employer's interest in a subsidiary (within
                 the meaning of section 409(d)(3) of the Code) if the Employer
                 continues to maintain this Plan. However, a distribution may
                 be made under this paragraph only to an Employee who continues
                 employment with such subsidiary.

                 In addition, this requirement is satisfied only if the
                 purchaser does not maintain the Plan after the





                                       38
<PAGE>   41
                 disposition. A purchaser maintains the plan of the seller if 
                 it adopts the plan or otherwise becomes an employer whose 
                 employees accrue benefits under the Plan. A purchaser also 
                 maintains the Plan if the Plan is merged or consolidated 
                 with, or any assets or liabilities are transferred from the 
                 Plan to a plan maintained by the purchaser in a transaction 
                 subject to section 414(l)(1) of the Code. A purchaser is
                 not treated as maintaining the Plan merely because the Plan 
                 that it maintains accepts rollover contributions of amounts 
                 distributed by the Plan.

                 A distribution may be made under this paragraph only if it is
                 a lump sum distribution. The term "lump sum distribution" has
                 the same meaning provided in section 402(e)(4) of the Code,
                 without regard to subparagraphs (A)(i) through (iv), (B), and
                 (H) of that section.

         (D)     In the case of Elective Deferral Contributions only, the
                 attainment of age 59-1/2, as described in Section 10.1 of the
                 Plan.

         (E)     In the case of Elective Deferral Contributions only, the
                 hardship of the Participant, as described in Section 10.4 of
                 the Plan.

6.4      COMMENCEMENT OF DISTRIBUTIONS. Notwithstanding the provisions of the
         preceding Timing of Distributions Section, distributions to a
         Participant will commence no later than the date determined in
         accordance with the provisions of this Section.

         Distribution to a Participant must commence no later than the required
         beginning date. The first required beginning date of a Participant is
         the first day of April of the calendar year following the calendar
         year in which the Participant attains age 70-1/2.

         The required beginning date of a Participant who attains 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
         retirement or attainment of age 70-1/2 occurs, provided the
         Participant was not a 5% owner in the Plan Year ending in the year in
         which the Participant attained age 66-1/2 or any later Plan Year. A
         Participant is treated as a 5% owner for purposes of this section if
         such Participant is a 5% owner as defined in section 416(i) of the
         Code (determined in accordance with section 416 but without regard to
         whether the Plan is Top-Heavy). The required beginning date of a
         Participant who is a 5% owner during any year beginning after December
         31, 1979, is the first day of April following the later of:

         (A)     the calendar year in which the Participant attained age 
                 70-1/2, or

         (B)     the earlier of the calendar year with or within which ends the
                 Plan Year in which the Participant becomes a 5% owner, or the
                 calendar year in which the Participant retires.

         Once distributions have begun to a 5% owner under this section, they
         must continue to be distributed, even if the Participant ceases to be
         a 5% owner in a subsequent year. Distribution to such Participant must
         commence no later than the first day of April following the calendar
         year in which the Participant's Termination of Employment occurs.

         If distribution to any Participant is made in other than a single sum
         payment, the second payment shall be distributed no later than the
         December 31 following the April 1 by which the first payment was
         required to be distributed. Each succeeding payment shall be
         distributed no later than each December 31 thereafter.

6.5      DISTRIBUTION REQUIREMENTS.

         (A)     Except as otherwise provided in Article VIII, the requirements
                 of this Section shall apply to any





                                       39
<PAGE>   42
                 distribution of a Participant's Accrued Benefit.

         (B)     All distributions required under this Article shall be
                 determined and made in accordance with the Income Tax
                 Regulations under section 401(a)(9), including the minimum
                 distribution incidental benefit requirement of section
                 1.401(a)(9)-2 of the regulations.

         (C)     Limits on Settlement Options. Distributions, if not made in a
                 lump sum, may only be made over one of the following periods
                 (or a combination thereof):

                 (1)      the life of the Participant,

                 (2)      the life of the Participant and a designated 
                          Beneficiary,

                 (3)      a period certain not extending beyond the life
                          expectancy of the Participant, or

                 (4)      a period certain not extending beyond the joint and
                          last survivor expectancy of the Participant and a
                          designated Beneficiary.

         (D)     Minimum Amounts to be Distributed.

                 (1)      If the Participant's entire Vested Interest is to be
                          distributed in other than a lump sum, then the amount
                          to be distributed each year must be at least an
                          amount equal to the quotient obtained by dividing the
                          Participant's entire Vested Interest by the life
                          expectancy of the Participant or the joint and last
                          survivor expectancy of the Participant and designated
                          Beneficiary. Life expectancy and joint and last
                          survivor expectancy are computed by the use of the
                          return multiples contained in section 1.72-9 of the
                          Income Tax Regulations. For purposes of this
                          computation, a Participant's life expectancy may be
                          recalculated no more frequently than annually;
                          however, the life expectancy of a Beneficiary other
                          than the Participant's Spouse may not be
                          recalculated.

                 (2)      If the Participant's Spouse is not the designated
                          Beneficiary, the method of distribution selected must
                          assure that at least 50% of the present value of the
                          amount available for distribution is paid within the
                          life expectancy of the Participant.

                 (3)      For calendar years beginning after December 31, 1988,
                          the amount to be distributed each year, beginning
                          with distributions for the first distribution
                          calendar year, shall not be less than the quotient
                          obtained by dividing the Participant's benefit by the
                          lesser of (1) the applicable life expectancy or (2)
                          if the Participant's Spouse is not the designated
                          Beneficiary, the applicable divisor determined from
                          the table set forth in Q&A-4 of section 1.401(a)(9)-2
                          of the Income Tax Regulations. Distributions after
                          the death of the Participant shall be distributed
                          using the applicable life expectancy in subsection
                          (d)(1) above as the relevant divisor without regard
                          to regulations section 1.401(a)(9)-2.

                 (4)      The minimum distribution required for the
                          Participant's first distribution calendar year must
                          be made on or before the Participant's required
                          beginning date. The minimum distribution for other
                          calendar years, including the minimum distribution
                          for the distribution calendar year in which the
                          Employee's required beginning date occurs, must be
                          made on or before December 31 of that distribution
                          calendar year.

6.6      NON-TRANSFERABLE. The Participant's right to any Annuity payments,
         benefits, and refunds is not transferable and shall be free from the
         claims of all creditors to the fullest extent permitted by law.

6.7      DEATH DISTRIBUTION PROVISIONS. If the Participant dies before
         distribution of his Vested Interest commences, the following
         provisions shall apply:

         (A)     If a distribution is to be made to a Beneficiary other than the
                 Surviving Spouse:

                 (1)      If the present value of the Participant's Vested
                          Interest exceeds (or at the time of any prior
                          distribution exceeded) $3,500, unless the Beneficiary
                          elects another form of distribution, that portion of
                          the Participant's Vested Interest payable to the
                          Beneficiary will be distributed in the form of a
                          single sum cash payment within a reasonable period of
                          time after the Plan Administrator is notified of the
                          Participant's death.

                 (2)      If the present value of the Participant's Vested
                          Interest is $3,500 or less at the time it becomes
                          payable, the distribution shall always be made in the
                          form of a single sum cash payment and shall be paid
                          within a reasonable period of time after the Plan
                          Administrator is notified of the Participant's death.

         (B)     If the distribution is to be made to a Beneficiary who is the
                 Surviving Spouse, such distribution will be made in accordance
                 with the following:

                 (1)      If the Participant had never elected a life Annuity
                          form of distribution under the Plan:

                          (a)     If the present value of the Participant's
                                  Vested Interest exceeds (or at the time of
                                  any prior distribution exceeded) $3,500,
                                  unless the surviving spouse elects another
                                  form of distribution, that portion of the
                                  Participant's Vested Interest payable to the
                                  Surviving Spouse will be distributed in the
                                  form of a single sum cash payment within a
                                  reasonable period of time after the Plan
                                  Administrator is notified of the
                                  Participant's death.

                          (b)     If the present value of the Participant's
                                  Vested Interest payable to the Surviving
                                  Spouse is $3,500 or less at the time it
                                  becomes payable, the distribution shall
                                  always be made in the form of a single sum
                                  cash payment and shall be made within a
                                  reasonable period of time after the Plan
                                  Administrator is notified of the
                                  Participant's death.

                 (2)      If the Participant had previously elected a life
                          Annuity form of distribution under the Plan:

                          (a)     If the present value of the Participant's
                                  Vested Interest exceeds (or at the time of
                                  any prior distribution exceeded) $3,500 and
                                  is immediately distributable (as defined in
                                  Section 8.5), the Surviving Spouse must
                                  consent to the distribution before it is
                                  made. If the Surviving Spouse does not
                                  consent to a distribution, all benefits shall
                                  be deferred to a date that complies with the
                                  terms of Section 6.8 (B).

                                  The distribution shall be made in accordance 
                                  with the provisions of Section 8.3.

                          (b)     If the present value of the Participant's
                                  Vested Interest is $3,500 or less at the time
                                  it becomes payable, the distribution shall
                                  always be made in the form of a single sum
                                  cash payment and shall be paid within a
                                  reasonable period of time after the Plan
                                  Administrator is notified of the
                                  Participant's death.

6.8      DEATH DISTRIBUTION COMMENCEMENT DATE. Upon the death of the
         Participant, the following distribution provisions shall take effect:


                                       41
<PAGE>   44
         (A)     If the Participant dies after distribution of his entire
                 Vested Interest has commenced, the remaining portion of such
                 Vested Interest will continue to be distributed at least as
                 rapidly as under the method of distribution being used prior
                 to the Participant's death.

                 In no event shall distribution of the Participant's remaining
                 Vested Interest be made in a lump sum after the Participant's
                 death unless such distribution is consented to, in writing, by
                 the Participant's Surviving Spouse, if any.

         (B)     If the Participant dies before distribution of his Vested
                 Interest commences, the Participant's entire Vested Interest
                 will be distributed no later than five years after the
                 Participant's death except to the extent that an election is
                 made to receive distributions in accordance with (1) or (2)
                 below:

                 (1)      If any portion of the Participant's Vested Interest
                          is payable to a designated Beneficiary, distributions
                          may be made in substantially equal installments over
                          the life or life expectancy of the designated
                          Beneficiary (or over a period not extending beyond
                          the life expectancy of such Beneficiary), commencing
                          no later than one year after the Participant's death;

                 (2)      If the designated Beneficiary is the Participant's
                          Surviving Spouse, the date distributions are required
                          to begin in accordance with (1) above shall not be
                          earlier than the date on which the Participant would
                          have attained age 70-1/2. However, the Surviving
                          Spouse may elect, at any time following the
                          Participant's death, to defer the date on which
                          distributions will begin until no later than the date
                          on which the Participant would have attained age
                          70-1/2 and, if the Spouse dies before payments begin,
                          subsequent distributions shall be made as if the
                          Spouse had been the Participant.

         (C)     For purposes of (B) above, payments will be calculated by use
                 of the return multiples specified in section 1.72-9 of the
                 Income Tax Regulations. Life expectancy of a Surviving Spouse
                 may be recalculated annually; however, in the case of any
                 other designated Beneficiary, such life expectancy will be
                 calculated at the time payment first commences without further
                 recalculation.

         (D)     For purposes of this Section (Death Distribution Commencement
                 Date) any amount paid to a child of the Participant will be
                 treated as if it had been paid to the Surviving Spouse if the
                 amount becomes payable to the Surviving Spouse when the child
                 reaches the age of majority.

6.9      ALTERNATE PAYEE SPECIAL DISTRIBUTION. Distributions pursuant to
         Section 16.8 may be made without regard to the age or employment
         status of the Participant.

                                  ARTICLE VI-A
                                DIRECT ROLLOVERS



6A.1     Notwithstanding any provision of the Plan to the contrary that would
         otherwise limit a Distributee's election under this Article, a
         Distributee may elect, at the time and in the manner prescribed by the
         Plan Administrator, to have any portion of an Eligible Rollover
         Distribution paid directly to an Eligible Retirement Plan specified by
         the Distributee in a Direct Rollover, except as otherwise provided by
         the Employer's administrative procedures as permitted by regulations.
         In addition, a Distributee's election of a Direct Rollover shall be
         subject to the following requirements:

         (A)     If the Distributee elects to have only a portion of an
                 Eligible Rollover Distribution paid to an Eligible Retirement
                 Plan in a Direct Rollover, that portion must be equal to at
                 least $500.

         (B)     If the entire amount of a Distributee's Eligible Rollover
                 Distribution is $500 or less, the distribution may not be
                 divided. Instead, the entire amount must either be paid to the
                 Distributee or to an Eligible Retirement Plan in a Direct
                 Rollover.

         (C)     A Distributee may not elect a Direct Rollover if the
                 Distributee's Eligible Rollover Distributions during a year
                 are reasonably expected by the Plan Administrator to total
                 less than $200 (or any lower minimum amount specified by the
                 Plan Administrator).

         (D)     A Distributee's election to make or not make a Direct Rollover
                 with respect to one payment in a series of periodic payments
                 shall apply to all subsequent payments in the series, except
                 that a Distributee shall be permitted at any time to change,
                 with respect to subsequent payments in the series of periodic
                 payments, a previous election to make or not make a Direct
                 Rollover. A change of election shall be accomplished by the
                 Distributee notifying the Plan Administrator of the change.
                 Such notice must be in the form and manner prescribed by the
                 Plan Administrator.

6A.2     Definitions.

         (A)     Direct Rollover:  A Direct Rollover is a payment by the plan
                 to the Eligible Retirement Plan specified by the Distributee.

         (B)     Distributee:  A Distributee includes an Employee or former
                 Employee. In addition, the Employee's or former Employee's
                 Surviving Spouse and the Employee's or former Employee's
                 Spouse who is the alternate payee under a qualified domestic
                 relations order, as defined in section 414(p) of the Code, are
                 Distributees with regard to the interest of the Spouse or
                 former Spouse.

         (C)     Eligible Retirement Plan:  An Eligible Retirement Plan is an
                 individual retirement account described in section 408(a) of
                 the code, an individual retirement annuity described in
                 section 408(b) of the Code, an annuity plan described in
                 section 403(a) of the Code, or a qualified trust described in
                 section 401(a) of the Code, that accepts the Distributee's
                 Eligible Rollover Distribution. However, in the case of an
                 Eligible Rollover Distribution to the Surviving Spouse, an
                 Eligible Retirement Plan is an individual retirement account
                 or an individual retirement annuity.

         (D)     Eligible Rollover Distribution:  An Eligible Rollover
                 Distribution is any distribution of all or any portion of the
                 balance to the credit of the Distributee, except that an
                 Eligible Rollover Distribution

                 does not include: any distribution that is one of a series of
                 substantially equal periodic payments (not less frequently 
                 than annually) made for the life (or life expectancy) of the 
                 Distributee or the joint lives (or joint life expectancies) 
                 of the Distributee and the Distributee's designated
                 beneficiary, or for a specified period of ten years or more; 
                 any distribution to the extent such distribution is required 
                 under section 401(a)(9) of the Code; and the portion of any 
                 distribution that is not includible in gross income
                 (determined without regard to the exclusion for net unrealized 
                 appreciation with respect to employer securities).

                    JOINT AND SURVIVOR ANNUITY REQUIREMENTS



8.1      GENERAL. The provisions of this Article shall take precedence over any
         conflicting provision in this Plan.

         The provisions of this Article shall apply to any Participant who is
         credited with at least one Hour of Service with the Employer on or
         after August 23, 1984, and such other Participants as provided in
         Section 8.7, unless:

         (A)     upon the death of the Participant the Participant's entire
                 Vested Interest will be paid to the Participant's Surviving
                 Spouse, but if there is no Surviving Spouse, or, if the
                 Surviving Spouse has already consented in a manner conforming
                 to a Qualified Election, then to the Participant's designated
                 Beneficiary;

         (B)     the Participant does not elect payments in the form of a Life
                 Annuity and has not previously elected payments in the form of
                 a Life Annuity under the Plan, and

         (C)     as to the Participant, the Plan is not a direct or indirect
                 transferee of a defined benefit plan, money purchase pension
                 plan (including a target benefit plan), stock bonus, or
                 profit-sharing plan which would otherwise provide for a Life
                 Annuity form of payment to the Participant.

8.2      PAYMENT OF QUALIFIED JOINT AND SURVIVOR ANNUITY. Unless an optional
         form of benefit is selected pursuant to a Qualified Election within
         the ninety-day period ending on the first day on which all events have
         occurred which entitle the Participant to a benefit, a married
         Participant's Vested Interest will be paid in the form of a Qualified
         Joint and Survivor Annuity.

         An unmarried Participant will be provided a single Life Annuity unless
         the Participant elects another form of benefit during the applicable
         Election Period.

8.3      PAYMENT OF QUALIFIED PRERETIREMENT SURVIVOR ANNUITY. Unless an
         optional form of benefit has been selected within the Election Period
         pursuant to a Qualified Election, if a married Participant dies before
         his Annuity Starting Date, then the Participant's entire Vested
         Interest shall be applied toward the purchase of an immediate Annuity
         for the life of the Surviving Spouse. As an alternative to receiving
         the benefit in this form of an Annuity, the Surviving Spouse may elect
         to receive a single cash payment or any other form of payment provided
         for in the Plan within a reasonable time after the Participant's
         death.

8.4      DEFINITIONS.

         (A)     Election Period:  The period which begins on the first day of
                 the Plan Year in which the Participant attains age 35 and ends
                 on the date of the Participant's death. If a Participant
                 separates from Service prior to the first day of the Plan Year
                 in which age 35 is attained, with respect to the account
                 balance as of the date of separation, the Election Period
                 shall begin on the date of separation.

                 A Participant who has not attained age 35 as of the end of a
                 Plan Year, may make a special Qualified Election to waive the
                 Qualified Preretirement Survivor Annuity for the period
                 beginning





                                       46
<PAGE>   49
                 on the date of such election and ending on the first day of 
                 the Plan Year in which the Participant will attain age 35. 
                 Such election shall not be valid unless the Participant 
                 receives a written explanation of the Qualified Preretirement 
                 Survivor Annuity in such terms as are comparable to the 
                 explanation required under Section 8.6 (A).  Qualified 
                 Preretirement Survivor Annuity coverage will be automatically 
                 reinstated as of the first day of the Plan Year in which
                 the Participant attains age 35. Any new waiver on or after 
                 such date shall be subject to the full requirements of this 
                 Article.

         (B)     Qualified Election: A waiver of a Qualified Joint and Survivor
                 Annuity or a Qualified Preretirement Survivor Annuity. Any
                 waiver of a Qualified Joint and Survivor Annuity or a
                 Qualified Preretirement Survivor Annuity shall not be
                 effective unless: (a) the Participant's Spouse consents in
                 writing to the election; (b) the election designates a
                 specific Beneficiary, including any class of Beneficiaries or
                 any contingent Beneficiaries, which may not be changed without
                 spousal consent (or the Spouse expressly permits designations
                 by the Participant without any further spousal consent); (c)
                 the Spouse's consent acknowledges the effect of the election;
                 and (d) the Spouse's consent is witnessed by a Plan
                 representative or notary public. Additionally, a Participant's
                 waiver of the Qualified Joint and Survivor Annuity shall not
                 be effective unless the election designates a form of benefit
                 payment which may not be changed without spousal consent (or
                 the Spouse expressly permits designations by the Participant
                 without any further spousal consent). If it is established to
                 the satisfaction of a Plan representative that such written
                 consent cannot be obtained because:

                 (1)      there is no Spouse;

                 (2)      the Spouse cannot be located;

                 (3)      the Participant is legally separated or has been
                          abandoned within the meaning of local law, and the
                          Participant has a court order to such effect;

                 (4)      of other circumstances as the Secretary of the
                          Treasury may by regulations prescribe,

                 the Participant's election to waive coverage will be
                 considered a Qualified Election.

                 Any consent by a Spouse obtained under this provision (or
                 establishment that the consent of a Spouse may not be
                 obtained) shall be effective only with respect to such Spouse.
                 A consent that permits designations by the Participant without
                 any requirement of further consent by such Spouse must
                 acknowledge that the Spouse has the right to limit consent to
                 a specific Beneficiary, and a specific form of benefit where
                 applicable, and that the Spouse voluntarily elects to
                 relinquish either or both of such rights. A revocation of a
                 prior waiver may be made by a Participant without the consent
                 of the Spouse at any time before the commencement of benefits.
                 The number of revocations shall not be limited.  No consent
                 obtained under this provision shall be valid unless the
                 Participant has received notice as provided in Section 8.6
                 below.

         (C)     Qualified Joint and Survivor Annuity:  An immediate Annuity
                 for the life of the Participant with a survivor Annuity for
                 the life of the Spouse which is not less than 50% and not more
                 than 100% of the amount of the Annuity which is payable during
                 the joint lives of the Participant and the Spouse and which is
                 the amount of benefit which can be purchased with the
                 Participant's entire Vested Interest. If no survivor Annuity
                 percentage has been specified in an election, the percentage
                 payable to the Spouse will be 50%.

                 Notwithstanding the above paragraph, a Qualified Joint and
                 Survivor Annuity for an unmarried





                                       47
<PAGE>   50
                 Participant shall mean an Annuity for the life of the 
                 Participant.

         (D)     Qualified Preretirement Survivor Annuity:  A survivor Annuity
                 for the life of the Spouse in the amount which can be
                 purchased with the Participant's entire Vested Interest.

         (E)     Spouse (Surviving Spouse):  The Spouse or Surviving Spouse of
                 the Participant. A former Spouse may be treated as the Spouse
                 or Surviving Spouse to the extent provided under a Qualified
                 Domestic Relations Order as described in Internal Revenue Code
                 section 414(p).

8.5      CONSENT REQUIREMENTS. Only the Participant need consent to the
         commencement of a distribution in the form of a Qualified Joint and
         Survivor Annuity while the account balance is immediately
         distributable. Neither the consent of the Participant nor the
         Participant's Spouse shall be required to the extent that a
         distribution is required to satisfy section 401(a)(9) or section 415
         of the Code. An account balance is immediately distributable if any
         part of the account balance could be distributed to the Participant
         (or Surviving Spouse) before the Participant attains (or would have
         attained if not deceased) the later of Normal Retirement Age or age
         62.

8.6      NOTICE REQUIREMENTS.

         (A)     In the case of a Qualified Joint and Survivor Annuity as
                 described in Section 8.4 (C), the Plan Administrator shall
                 provide each Participant within a reasonable period prior to
                 the commencement of benefits a written explanation of:  (i)
                 the terms and conditions of a Qualified Joint and Survivor
                 Annuity; (ii) the Participant's right to make and the effect
                 of an election to waive the Qualified Joint and Survivor
                 Annuity form of benefit; (iii) the rights of a Participant's
                 Spouse; (iv) the right to make, and the effect of, a
                 revocation of a previous election to waive the Qualified Joint
                 and Survivor Annuity; (v) a general description of the
                 eligibility conditions and other material features of the
                 optional forms of benefit; and (vi) sufficient additional
                 information to explain the relative values of the optional
                 forms of benefit available to them under this Plan.

                 the Plan Year in which the Participant attains age 35, a
                 written explanation of the Qualified Preretirement Survivor
                 Annuity in such terms and in such manner as would be
                 comparable to the explanation provided for meeting the
                 requirements of Section 8.6 (A) to a Qualified Joint and
                 Survivor Annuity.

                 If a Participant enters the Plan after the first day of the
                 Plan Year in which the Participant attained age 32, the Plan
                 Administrator shall provide notice no later than the close of
                 the second Plan Year succeeding the entry of the Participant
                 in the Plan.

                 If a Participant enters the Plan after he has attained age 35,
                 the Plan Administrator shall provide notice within a
                 reasonable period of time following the entry of the
                 Participant in the Plan.

                 Participant attains age 35, the Plan Administrator shall
                 provide notice within one year of such Termination of
                 Employment.

                          (b)     dies on or after Normal Retirement Age while 
                                  still working for the Employer; or

                          (c)     begins to receive payments on or after the 
                                  Qualified Early Retirement Age; or

                          (d)     separates from Service on or after attaining
                                  Normal Retirement Age (or the Qualified Early
                                  Retirement Age) and after satisfying the
                                  eligibility requirements for the payment of
                                  benefits under the Plan and thereafter dies
                                  before beginning to receive such benefits;

                          then such benefits will be received under this Plan
                          in the form of a Qualified Joint and Survivor
                          Annuity, unless the Participant has elected otherwise
                          during the election period. The election period must
                          begin at least six months before the Participant
                          attains Qualified Early Retirement Age and end not
                          more than 90 days before the commencement of
                          benefits. Any election hereunder will be in writing
                          and may be changed by the Participant at any time.

                 (2)      Election of Early Survivor Annuity:  A Participant
                          who is employed after attaining the Qualified Early
                          Retirement Age will be given the opportunity to
                          elect, during the election period, to have a survivor
                          annuity payable on death. If the Participant elects
                          the survivor annuity, payments under such Annuity
                          must not be less than the payments which would have
                          been made to the Spouse under the Qualified Joint and
                          Survivor Annuity if the Participant had retired on
                          the day before his or her death. Any election under
                          this provision will be in writing and may be changed
                          by the Participant at any time. The election period
                          begins on the later of (1) the 90th day before the
                          Participant attains the Qualified Early Retirement
                          Age, or (2) the date on which participation begins,
                          and ends on the date the Participant terminates
                          employment.

                                           on which the Participant may elect
                                           to receive retirement benefits; or

                                  (ii)     the first day of the 120th month
                                           beginning before the Participant

                                   ARTICLE IX
                           TERMINATION OF EMPLOYMENT



9.1      DISTRIBUTION. As of a Participant's Termination of Employment, he
         shall be entitled to receive a distribution of his entire Vested
         Interest. Such distribution shall be further subject to the terms and
         conditions of Article VI.

         If at the time of his Termination of Employment the Participant's
         Vesting Percentage is not 100% and the Participant does not take a
         distribution from the portion of his Vested Interest subject to the
         Vesting Percentage, the non-vested portion of his Participant's
         Account will become a Forfeiture upon the date the Participant incurs
         five consecutive One-Year Breaks in Service.

         If at the time of his Termination of Employment the Participant's
         Vesting Percentage is not 100% and such Participant does take a
         distribution from the portion of his Vested Interest subject to the
         Vesting Percentage, or if the Participant's Vesting Percentage is 0%,
         the non-vested portion of his Participant's Account will become a
         Forfeiture immediately.

         If the Participant, whose non-vested portion of his Participant's
         Account became a Forfeiture in accordance with the terms of the
         preceding paragraph, is later rehired by the Employer and re-enrolls
         in the Plan, Subsection (A), (B) or (C) below, as applicable, will
         apply:

         (A)     If the Participant was 0% vested at his Termination of
                 Employment and did not incur five consecutive One-Year Breaks
                 in Service after such date, the amount which became a
                 Forfeiture, if any, shall be restored by the Employer at the
                 time such Participant re-enrolls in the Plan. The Forfeiture,
                 so restored, shall be included as part of that portion of his
                 Participant's Account subject to the Vesting Percentage.

         (B)     If the Participant's Vesting Percentage was not 100% at his
                 Termination of Employment and if the Participant did not incur
                 five consecutive One-Year Breaks in Service after such date,
                 the Participant shall be entitled to repay the portion of the
                 distribution made at his Termination of Employment derived
                 from Employer Contributions. The portion of the repayment that
                 is attributable to amounts that were subject to the Vesting
                 Percentage will no longer be considered a distribution for
                 purposes of determining the Participant's Vested Interest. The
                 repayment of such portion must be made before the Participant
                 has incurred five consecutive One-Year Breaks in Service
                 following the date he received the distribution or five years
                 after the Participant is rehired by the Employer, whichever is
                 earlier.

                 If the Participant elects to make such repayment, the amount
                 which became a Forfeiture, if any, shall be restored by the
                 Employer at the same time such repayment is made. The
                 Forfeiture, so restored, and the repayment shall be included
                 as part of that portion of his Participant's Account subject
                 to the Vesting Percentage. However, if the Participant does
                 not elect to repay the distribution made in accordance with
                 this Article within the period of time specified above, that
                 Forfeiture shall remain a Forfeiture.

         (C)     If the Participant had incurred five consecutive One-Year
                 Breaks in Service after his Termination of Employment, the
                 amount which became a Forfeiture shall remain a Forfeiture and
                 such Participant shall be prohibited from repaying a
                 distribution made at his Termination of





                                       51

                 Employment.

9.2      NO FURTHER RIGHTS OR INTEREST. A Participant shall have no further
         interest in or any rights to any portion of his Participant's Account
         that becomes a Forfeiture due to his Termination of Employment once
         the Participant incurs five consecutive One-Year Breaks in Service in
         accordance with Article II.

9.3      APPLICATION OF FORFEITURES. Any Forfeiture arising in accordance with
         the provisions of Section 9.1 shall be used by the Employer to reduce
         and in lieu of the contributions made by the Employer next due under
         Article IV, or to pay Plan expenses, at the earliest opportunity after
         such Forfeiture becomes available.

         The provisions of the preceding sentence notwithstanding, in the event
         that a former Participant is rehired by the Employer and the Employer
         is required by the provisions of Section 9.1 of this Plan to restore
         the amount of a separate account that had been created upon such
         Participant's prior Termination of Employment and later forfeited,
         Forfeitures, if any, will first be used to restore such separate
         account to its value as of such Participant's prior Termination of
         Employment date. In the event that the available Forfeitures are not
         sufficient to make such restoration, the Employer will make an
         additional contribution sufficient to make such restoration.

                                  WITHDRAWALS



10.1     WITHDRAWAL AFTER AGE 59-1/2. A Participant who was a Participant in
         the Talbert & Associates, Inc. Savings Plan and Trust prior to January
         1, 1993 may elect to withdraw from his Participant's Account, at any
         time, an amount which is equal to any whole percentage (not exceeding
         100%) of his Vested Interest in his Participant's Account, as of
         January 1, 1993, attributable to:

         o       Elective Deferral Contributions, including earnings

         o       Matching Contributions that are not designated as Qualified
                 Matching Contributions, including earnings

         o       Nonelective Contributions that are not designated as Qualified
                 Nonelective Contributions, including earnings.

10.2     WITHDRAWAL OF CONTRIBUTIONS AFTER 60 MONTHS OF PARTICIPATION. A
         Participant who was a Participant in the Serv-Tech, Inc. Employee
         401(k) Retirement Plan prior to January 1, 1993 and has been a
         Participant for at least 60 consecutive months may elect to withdraw
         from his Participant's Account, once every Plan Year, an amount equal
         to any whole percentage (not exceeding 100%) of his Vested Interest in
         his Participant's Account, as of January 1, 1993, attributable to the
         value of:

         o       Matching Contributions that are not designated as Qualified
                 Matching Contributions, including earnings

         o       Nonelective Contributions that are not designated as Qualified
                 Nonelective Contributions, including earnings.

10.3     WITHDRAWAL FOR SERIOUS FINANCIAL HARDSHIP OF CONTRIBUTIONS OTHER THAN
         ELECTIVE DEFERRAL CONTRIBUTIONS. In the event a Participant suffers a
         Serious Financial Hardship, such Participant may withdraw a portion of
         his Vested Interest attributable to the following to meet such need:

         o       Matching Contributions that are not designated as Qualified
                 Matching Contributions, including earnings

         o       Nonelective Contributions that are not designated as Qualified

         o       Rollover Contributions, including earnings.

         In no event may any such withdrawal exceed the amount required to meet
         the immediate financial need created by the Serious Financial
         Hardship.

         Such Serious Financial Hardship must be shown by positive evidence

         magnitude to impair the Participant's financial security. Withdrawals
         shall be determined in a consistent and nondiscriminatory manner, and
         shall not affect the Participant's right

<PAGE>   56
         under the Plan to make additional withdrawals or to continue to be a
         Participant.

10.4     WITHDRAWAL FOR SERIOUS FINANCIAL HARDSHIP OF ELECTIVE DEFERRAL
         CONTRIBUTIONS. Distributions of Elective Deferral Contributions may be
         made to a Participant in the event of a hardship. For purposes of this
         section, a distribution is made on account of hardship only if the
         distribution is made both on account of an immediate and heavy
         financial need of the Employee and is necessary to satisfy the
         financial need. In addition, any distribution on account of hardship
         shall be limited to the distributable amount described in paragraph
         (C) of this section.

         (A)     The following are the only financial needs considered
                 immediate and heavy for purposes of this section:

                 (1)      Expenses for medical care described in section 213(d)
                          of the Code previously incurred by the Employee, the
                          Employee's Spouse, or any dependents of the Employee
                          (as defined in section 152 of the Code) or necessary
                          for these persons to obtain medical care described in
                          section 213(d) of the Code;

                 (2)      Payment of tuition and related educational fees for
                          the next 12 months of post-secondary education for
                          the Employee, his Spouse, children, or dependents (as
                          defined in section 152 of the Code);

                 (3)      Costs directly related to the purchase of a principal
                          residence for the Employee (excluding mortgage
                          payments); or

                 (4)      Payments necessary to prevent the eviction of the
                          Employee from the Employee's principal residence or
                          foreclosure on the mortgage on that residence.

         (B)     The Participant shall specify on the application for a
                 hardship withdrawal whether the Participant elects the
                 provision of (1) or (2) below to be used in determining the
                 necessity of the hardship.

                 (1)      A distribution will be considered as necessary to
                          satisfy an immediate and heavy financial need of the
                          Employee only if all of the following requirements
                          are satisfied:

                          (a)     The hardship distribution is not in excess of
                                  the amount of the immediate and heavy
                                  financial need of the Employee. The amount of
                                  an immediate and heavy financial need may
                                  include the amounts necessary to apply any
                                  federal, state, or local income taxes or
                                  penalties reasonably anticipated to result
                                  from the distribution.

                          (b)     The Employee had obtained all distributions,
                                  other than hardship distributions, and all
                                  nontaxable (at the time of the loan) loans
                                  currently available under all plans
                                  maintained by the Employer.

                          (c)     The Employee is suspended from making
                                  Elective Deferral Contributions to the Plan
                                  for at least 12 months after receipt of the
                                  hardship distribution In addition, the
                                  Employee must be prohibited under the terms
                                  of the plan or an otherwise enforceable
                                  agreement from making Elective Deferral
                                  Contributions and Employee Contributions to
                                  all other plans maintained by the Employer
                                  for at least 12 months after receipt of the
                                  hardship distribution.

                                  For this purpose, the phrase "all other 
                                  plans of the Employer" means all qualified





                                       54

                                  and nonqualified plans of deferred 
                                  compensation maintained by the
                                  Employer. The phrase includes a stock option,
                                  stock purchase, or similar plan, or a cash 
                                  or deferred arrangement that is part of a
                                  cafeteria plan within the meaning of section 
                                  125 of the Code. However, it does not include
                                  the mandatory employee contribution part of a
                                  benefit plan. It also does not include a 
                                  health or welfare benefit plan, including 
                                  one that is part of a cafeteria  plan within
                                  the meaning of section 125 of the Code.

                          (d)     The Employee may not make Elective Deferral
                                  Contributions to the Plan for the Employee's
                                  taxable year immediately following the
                                  taxable year of the hardship distribution in
                                  excess of the applicable limit under section
                                  402(g) of the Code for such taxable year less
                                  the amount of such Employee's Elective
                                  Deferral Contributions for the taxable year
                                  of the hardship distribution. In addition,
                                  all other plans maintained by the Employer
                                  must limit the Employee's Elective Deferral
                                  Contributions for the next taxable year to
                                  the applicable limit under section 402(g) of
                                  the Code for that year minus the Employee's
                                  Elective Deferral Contributions for the year
                                  of the hardship distribution.

                 (2)      A distribution will be treated as necessary to
                          satisfy a financial need if the Employer relies upon
                          the Employee's written representation, unless the
                          Employer has actual knowledge to the contrary, that
                          the need cannot reasonably be relieved:

                          (a)     Through reimbursement or compensation by 
                                  insurance or otherwise;

                          (b)     By liquidation of the Employee's assets;

                          (c)     By cessation of Elective Deferral 
                                  Contributions under the Plan; or

                          (d)     By other distributions or nontaxable (at the
                                  time of the loan) loans from plans maintained
                                  by the Employer or by any other employer, or
                                  by borrowing from commercial sources on
                                  reasonable commercial terms in an amount
                                  sufficient to satisfy the need.

                          A need cannot reasonably be relieved by one of the
                          actions listed above if the effect would be to
                          increase the amount of the need.

                          The amount of an immediate and heavy financial need
                          may include any amounts necessary to pay any federal,
                          state, or local income taxes or penalties reasonably
                          anticipated to result from the distribution.

         (C)     The distributable amount is equal to the Employee's total
                 Elective Deferral Contribution as of the date of distribution,
                 reduced by the amount of previous distributions of Elective
                 Deferral Contributions on account of hardship. The Employee's
                 total Elective Deferral Contributions shall not include income
                 allocable to such Elective Deferral Contributions.

10.5     WITHDRAWAL OF ROLLOVER CONTRIBUTIONS. Once during a Plan Year, at any
         time, a Participant may elect to withdraw from his Participant's
         Account an amount up to 100% of the value of that portion of his
         account attributable to his Rollover Contributions as defined in
         Article IV. Such an election shall become effective in accordance with
         the Notification Section below.

10.6     NOTIFICATION. The Participant shall notify the Administrator in
         writing of his election to make a





                                       55
<PAGE>   58
         withdrawal under the preceding provisions of this Article X. Any such
         election shall be effective as of the date specified in such notice,
         which date must be at least 15 days after such notice is filed.
         Payment of the withdrawal shall be subject to the terms and conditions
         of Article VI.

10.7     NON-REPAYMENT. Withdrawals made in accordance with this Article X may
         not be repaid.

10.8     SPOUSAL CONSENT TO WITHDRAWAL. Prior to obtaining a withdrawal in
         accordance with this Article X, a married Participant must obtain
         spousal consent in accordance with the provisions of Article VIII
         unless such Participant meets the requirements set forth in Sections
         8.1 (A), (B) and (C).

         Fiduciary shall act with the care, skill, prudence, and diligence
         under the circumstances that a prudent man acting in a like capacity
         and familiar with such matters would use in conducting an enterprise

         serve in more than one fiduciary capacity with respect to this Plan.

11.3     LIMITATIONS ON FIDUCIARY LIABILITY. Nothing in this Plan shall be
         construed to prevent any Fiduciary from receiving any benefit to which
         he may be entitled as a Participant or Beneficiary in this Plan, so
         long as the benefit is computed and paid on a basis which is
         consistent with the terms of this Plan as applied to all other
         Participants and Beneficiaries. Nor shall this Plan be interpreted to
         prevent any Fiduciary from receiving any reasonable compensation for
         services rendered, or for the reimbursement of expenses properly and
         actually incurred in the performance of his duties with the Plan;
         except that no Person so serving who already receives full-time pay

                               THE ADMINISTRATOR



12.1     DESIGNATION AND ACCEPTANCE. The Employer shall designate a person or

         Plan.

12.2     DUTIES AND AUTHORITY. The Administrator shall administer the Plan in a

         their Beneficiaries.

         The Administrator shall perform all such duties as are necessary to
         operate, administer, and manage the Plan in accordance with the terms
         thereof, including but not limited to the following:

         (A)     To determine all questions relating to a Participant's
                 coverage under the Plan;

         (B)     To maintain all necessary records for the administration of
                 the Plan;

         (C)     To compute and authorize the payment of retirement income and
                 other benefit payments to eligible Participants and
                 Beneficiaries;

         (D)     To interpret and construe the provisions of the Plan and to
                 make regulations which are not inconsistent with the terms
                 thereof; and

         (E)     To advise or assist Participants regarding any rights,
                 benefits, or elections available under the Plan.

         The Administrator shall take all such actions as are necessary to
         operate, administer, and manage the Plan as a retirement program which
         is at all times in full compliance with any law or regulation
         affecting this Plan.

         The Administrator may allocate certain specified duties of plan
         administration to an individual or group of individuals who, with
         respect to such duties, shall have all reasonable powers necessary or
         appropriate to accomplish them.

12.3     EXPENSES AND COMPENSATION. All expenses of administration may be paid
         out of the Trust fund unless paid by the Employer. Such expenses shall

         including, but not limited to, fees of accountants, counsel, and other
         specialists and their agents, and other costs of administering the
         Plan. Until paid, the expenses shall constitute a liability of the
         Trust fund. However, the Employer may reimburse the Trust fund for any
         administration expense incurred. Any administration expense paid to
         the Trust fund as a reimbursement shall not be considered an Employer
         Contribution. Nothing shall prevent the Administrator from receiving
         reasonable compensation for services rendered in administering this
         Plan, unless the Administrator already receives full-time pay from any
         Employer adopting the Plan.

12.4     INFORMATION FROM EMPLOYER. To enable the Administrator to perform his
         functions, the Employer shall supply full and timely information to

12.5     ADMINISTRATIVE COMMITTEE; MULTIPLE SIGNATURES. In the event that more
         than one person has been duly nominated to serve on the Administrative
         Committee and has signified in writing the acceptance of such
         designation, the signature(s) of one or more persons may be accepted
         by an interested party as conclusive evidence that the Administrative
         Committee has duly authorized the action therein set forth and as
         representing the will of and binding upon the whole Administrative
         Committee. No person receiving such documents or written instructions
         and acting in good faith and in reliance thereon shall be obliged to
         ascertain the validity of such action under the terms of this Plan and
         Trust. The Administrative Committee shall act by a majority of its
         members at the time in office and such action may be taken either by a
         vote at a meeting or in writing without a meeting.

12.6     RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR. The Administrator,
         or any member of the Administrative Committee, may resign at any time
         by delivering to the Employer a written notice of resignation, to take
         effect at a date specified therein, which shall not be less than 30
         days after the delivery thereof, unless such notice shall be waived.

         The Administrator may be removed with or without cause by the Employer
         by delivery of written notice of removal, to take effect at a date
         specified therein, which shall be not less than 30 days after delivery
         thereof, unless such notice shall be waived.

         The Employer, upon receipt of or giving notice of the resignation or
         removal of the Administrator, shall promptly designate a successor
         Administrator who must signify acceptance of this position in writing.
         In the event no successor is appointed, the Board of Directors of the

         assets. With regard to the assets entrusted to his care, the
         Investment Manager shall provide written instructions and directions
         to the Trustee, who shall in turn be entitled to rely upon such
         written direction. This appointment and delegation shall be evidenced
         by a signed written agreement.

12.8     DELEGATION OF DUTIES. The Administrator shall have the power, to the
         extent permitted by law, to delegate the performance of such Fiduciary

         administration of the Plan in the best interests of the Participants
         and their Beneficiaries.

                              PARTICIPANTS' RIGHTS



13.1     GENERAL RIGHTS OF PARTICIPANTS AND BENEFICIARIES. The Plan is
         established and the Trust assets are held for the exclusive purpose of
         providing benefits for such Employees and their Beneficiaries as have
         qualified to participate under the terms of the Plan.

13.2     FILING A CLAIM FOR BENEFITS. A Participant or Beneficiary or the
         Employer acting in his behalf, shall notify the Administrator of a
         claim of benefits under the Plan. Such request shall be in writing to
         the Administrator and shall set forth the basis of such claim and
         shall authorize the Administrator to conduct such examinations as may
         be necessary to determine the validity of the claim and to take such
         steps as may be necessary to facilitate the payment of any benefits to
         which the Participant or Beneficiary may be entitled under the terms
         of the Plan.

         A decision by the Administrator shall be made promptly and not later
         than 90 days after the Administrator's receipt of the claim of
         benefits under the Plan, unless special circumstances require an
         extension of the time for processing, in which case a decision shall
         be rendered as soon as possible, but not later than 180 days after the
         initial receipt of the claim of benefits.

13.3     DENIAL OF CLAIM. Whenever a claim for benefits by any Participant or
         Beneficiary has been denied by a Plan Administrator, a written notice,
         prepared in a manner calculated to be understood by the Participant,
         must be provided, setting forth (1) the specific reasons for the
         denial; (2) the specific reference to pertinent Plan provisions on
         which the denial is based; (3) a description of any additional
         material or information necessary for the claimant to perfect the
         claim and an explanation of why such material or information is
         necessary; and (4) an explanation of the Plan's claim review
         procedure.

13.4     REMEDIES AVAILABLE TO PARTICIPANTS. A Participant or Beneficiary may
         (1) request a review by a Named Fiduciary, other than the
         Administrator, upon written application to the Plan; (2) review
         pertinent Plan documents; and (3) submit issues and comments in
         writing to a Named Fiduciary. A Participant or Beneficiary shall have
         60 days after receipt by the claimant of written notification of a
         denial of a claim to request a review of a denied claim.

         A decision by a Named Fiduciary shall be made promptly and not later
         than 60 days after the Named Fiduciary's receipt of a request for
         review, unless special circumstances require an extension of the time
         for processing, in which case a decision shall be rendered as soon as
         possible, but not later than 120 days after receipt of a request for
         review. The decision on review by a Named Fiduciary shall be in
         writing and shall include specific reasons for the decision, written
         in a manner calculated to be understood by the claimant, and specific
         references to the pertinent Plan provisions on which the decision is
         based.

         A Participant or Beneficiary shall be entitled, either in his own name
         or in conjunction with any other interested parties, to bring such
         actions in law or equity or to undertake such administrative actions
         or to seek such relief as may be necessary or appropriate to compel
         the disclosure of any required information, to enforce or protect his
         rights, to recover present benefits due to him, or to clarify his
         rights to future benefits under the Plan.

13.5     REINSTATEMENT OF BENEFIT. In the event any portion of a distribution
         which is payable to a Participant or a Beneficiary shall remain unpaid
         on account of the inability of the Plan Administrator, after





                                       60
<PAGE>   63
         diligent effort, to locate such Participant or Beneficiary, the amount
         so distributable shall be treated as a Forfeiture under the Plan. If a
         claim is made by the Participant or Beneficiary for any benefit
         forfeited under this section, such benefit shall be reinstated.

13.6     LIMITATION OF RIGHTS. Participation hereunder shall not grant any
         Participant the right to be retained in the Service of the Employer or
         any other rights or interest in the Plan or Trust fund other than
         those specifically herein set forth.

13.7     PARTICIPANT CONTRIBUTIONS. Each Participant, regardless of his length
         of Service with the Employer, shall be fully vested (100%) at all
         times in any portion of his Participant's Account attributable to the
         following:

         o       Rollover Contributions.

13.8     MERGERS OR TRANSFERS. In the case of any merger or consolidation with
         or transfer of assets or liabilities to any other qualified plan after
         September 2, 1974, the following conditions must be met:

         (A)     The sum of the account balances in each plan shall equal the
                 fair market value (determined as of the date of the merger or
                 transfer as if the plans had then terminated) of the entire
                 plan assets.

         (B)     The assets of each plan shall be combined to form the assets
                 of the plan as merged (or transferred).

         (C)     Immediately after the merger (or transfer), each Participant
                 in the plan merged (or transferred) shall have an account
                 balance equal to the sum of the account balances the
                 Participant had in the plans immediately prior to the merger
                 (or transfer).

         (D)     Immediately after the merger (or transfer) each Participant in
                 the plan merged (or transferred) shall be entitled to the same
                 optional benefit forms as he was entitled to immediately prior
                 to the merger (or transfer).

         In the case of any merger or consolidation with or transfer of assets
         or liabilities to any defined benefit plan after September 2, 1974,
         one of the plans before such merger, consolidation, or transfer shall
         be converted into the other type of plan and either the rules
         described above, applicable to the merger of two defined contribution
         plans, or the rules applicable to the merger of two defined benefit
         plans, as appropriate, shall be applied.

13.9     PARTICIPANT'S ACCOUNT AND VALUATION. A Participant's Account shall be
         maintained on behalf of each Participant until such account is
         distributed in accordance with the terms of this Plan. At least once
         per year, as of the last day of the Plan Year, each Participant's
         Account shall be adjusted for any earnings, gains, losses,
         contributions, withdrawals, and expenses, attributable to such Plan
         Year, in order to obtain a new valuation of the Participant's Account.

13.10    INVESTMENT OF CONTRIBUTIONS. Each Participant shall have the exclusive
         authority to direct the investment of contributions made to his
         Participant's Account among the investment funds designated by the
         Employer. The Participant shall elect, by written notice to the Plan
         Administrator, to have a specified percentage invested in one or more
         investment fund(s), as long as the designated percentage for each fund
         is a whole number, and the sum of the percentages allocated is equal
         to 100%.

         On any normal business day during a Plan Year, the Participant may
         change the amount of the contributions pursuant to the above paragraph
         to be invested in a particular investment fund, subject to the rules
         of the investment funds in which the Participant's Account is invested
         or is to be invested.

         amount of the contributions pursuant to Section 13.10 above to be
         transferred between the investment funds designated by the Employer on
         any normal business day during the Plan Year.

         Notwithstanding the above, the transfer of amounts between investment
         funds shall be subject to the rules of the investment funds in which
         the Participant's Account is invested or is to be invested.

                                  ARTICLE XIV
                      AMENDMENT OR TERMINATION OF THE PLAN


14.1     AMENDMENT OF PLAN. The Employer shall have the right from time to time
         to modify or amend, in whole or in part, any or all provisions of the
         Plan, provided that a Board of Directors' resolution pursuant to such
         modification or amendment shall first be adopted and provided further
         that the modification or amendment is signed by the Employer, the
         Administrator and the Trustee. Upon any such modification or amendment
         the Administrator and the Trustee shall be furnished a copy thereof.
         No amendment shall deprive any Participant or Beneficiary of any
         Vested Interest hereunder. Any Participant having not less than three
         Years of Service shall be permitted to elect, in writing, to have his
         Vesting Percentage computed under the Plan without regard to such
         amendment.

         The period during which the election must be made by the Participant
         shall begin no later than the date the Plan Amendment is adopted and
         end no later than after the latest of the following dates:

        (A)     The date which is 60 days after the day the amendment is 
                adopted; or

        (B)     The date which is 60 days after the day the amendment becomes
                effective; or

        (C)     The date which is 60 days after the day the Participant is
                issued written notice of the amendment by the Employer or
                Administrator.

         Such written election by a Participant shall be made to the
         Administrator.

         No amendment to the Plan shall decrease a Participant's Account
         balance or eliminate an optional form of distribution. Notwithstanding
         the preceding sentence, a Participant's Account balance may be reduced
         to the extent permitted under Internal Revenue Code section 412(c)(8).
         Furthermore, no amendment to the Plan shall have the effect of
         decreasing a Participant's Vested Interest determined without regard
         to such amendment as of the later of the date such amendment is
         adopted or the date it becomes effective.

14.2     CONDITIONS OF AMENDMENT. The Employer shall not make any amendment
         which would cause the Plan to lose its status as a qualified plan
         within the meaning of section 401(a) of the Code.
 
14.3     TERMINATION OF THE PLAN. The Employer intends to continue the Plan
         indefinitely for the benefit of its Employees, but reserves the right
         to terminate the Plan at any time by resolution of its Board of
         Directors.  Upon such termination, the liability of the Employer to
         make contributions hereunder shall terminate.

14.4     FULL VESTING. Upon the termination or partial termination of the Plan,
         or upon complete discontinuance of Employer contributions, the rights
         of all affected Participants in and to the amounts credited to each
         such Participant's Account shall be 100% vested and nonforfeitable.

14.5     DISTRIBUTIONS UPON PLAN TERMINATION. If this Plan is terminated and
         the Employer does not maintain or establish another defined
         contribution plan, pursuant to Code section 401(k)(10)(A)(i), each
         Participant shall receive a total distribution, in the form of a
         lump-sum distribution as defined in Code section 401(k)(10)(B)(ii), of
         his Participant's Account in accordance with the terms and conditions
         of Article VI.


                                       63
<PAGE>   66
         However, if this Plan is terminated and the Employer does maintain or
         establish another defined contribution plan as discussed in the above
         paragraph, or if the Plan is only partially terminated, each
         Participant shall receive a total distribution of his Participant's
         Account, excluding any amounts attributable to Elective Deferral
         Contributions and contributions made by the Employer designated as
         401(k) contributions in accordance with the terms and conditions of
         Article VI. In such a situation, any amounts in a Participant's
         Account attributable to Elective Deferral Contributions and
         contributions made by the Employer designated as 401(k) contributions
         may be distributed only upon the occurrence of an event described in
         Article VI.

         No Participant and/or spousal consent will be required for a
         distribution where no successor plan exists.  However, if the Employer
         does maintain a successor plan, Participant and/or spousal consent is
         required for a distribution exceeding $3,500. The Participant's
         Account will be transferred to such successor plan if the required
         consents are not received.

14.6     APPLICATION OF FORFEITURES. Upon the termination of the Plan, any
         Forfeitures which have not been applied as of such termination to
         reduce the contribution made by the Employer shall be credited on a
         pro rata basis to the Participant's Account of the then Active
         Participants in the same manner as the last contribution made by the
         Employer under the Plan.

14.7     APPROVAL BY THE INTERNAL REVENUE SERVICE. Notwithstanding any other
         provisions of this Plan, the Employer's adoption of this Plan is
         subject to the condition precedent that the Employer's Plan shall be
         approved and qualified by the Internal Revenue Service as meeting the
         requirements of section 401(a) of the Internal Revenue Code and that
         the Trust established hereunder shall be entitled to exemption under
         the provisions of section 501(a). In the event the Plan initially
         fails to qualify and the Internal Revenue Service issues a final
         ruling that the Employer's Plan or Trust fails to so qualify as of the
         Effective Date, all liability of the Employer to make further
         contributions hereunder shall cease. The Plan Administrator, Trustee
         and any other Named Fiduciary shall be notified immediately by the
         Employer, in writing, of such failure to qualify. Upon such
         notification, the value of the Participants' Accounts shall be
         distributed in cash to the Employer, subject to the terms and
         conditions of Article VI.

         That portion of such distribution which is attributable to Participant
         Contributions as specified in Section 13.7, if any, shall be paid to
         the Participant, and the balance of such distribution shall be paid to
         the Employer.

14.8     SUBSEQUENT UNFAVORABLE DETERMINATION. If the Employer is notified
         subsequent to initial favorable qualification that the Plan is no
         longer qualified within the meaning of section 401(a) of the Internal
         Revenue Code, or that the Trust is no longer entitled to exemption
         under the provisions of section 501(a), and if the Employer shall fail
         within a reasonable time to make any necessary changes in order that
         the Plan and/or Trust shall so qualify, the Participants' Accounts
         shall be fully vested and nonforfeitable and shall be disposed of as
         if the Plan had terminated, in the manner set forth in this Article
         XIV.

                             SUBSTITUTION OF PLANS



15.1     SUBSTITUTION OF PLANS. Subject to the provisions of Section 13.8 the
         Employer may substitute an individually designed plan or a master or
         prototype plan for this Plan without terminating this Plan as embodied
         herein and this shall be deemed to constitute an amendment and
         restatement in its entirety of this Plan as heretofore adopted by the
         Employer; provided, however, that the Employer shall have certified to
         the Trustee that this Plan is being continued on a restated basis
         which meets the requirements of section 401(a) of the Internal Revenue
         Code and ERISA.

15.2     TRANSFER OF ASSETS. Upon 90 days written notification from the
         Employer and the Trustee that a different plan meeting the
         requirements set forth in Section 15.1 above has been executed and
         entered into by the Administrator and the Employer, and after the
         Trustee has been furnished the Employer's certification in writing
         that the Employer intends to continue the Plan as a qualified Plan
         under section 401(a) of the Internal Revenue Code and ERISA, assets
         which represent the value of all Participant's Accounts may be
         transferred in accordance with the instructions received from or on
         behalf of the Employer. The Trustee may rely fully on the
         representations or directions of the Employer with respect to any such
         transfer and shall be fully protected and discharged with respect to
         any such transfer made in accordance with such representations,
         instructions, or directions.

                                 MISCELLANEOUS



16.1     NON-REVERSION. This Plan has been established by the Employer for the
         exclusive benefit of the Participants and their Beneficiaries. Except
         as otherwise provided in Sections 14.7, 16.7, and 16.8, under no
         circumstances shall any funds contributed hereunder, at any time,
         revert to or be used by the Employer, nor shall any such funds or
         assets of any kind be used other than for the benefit of the
         Participants or their Beneficiaries.

16.2     GENDER AND NUMBER. When necessary to the meaning hereof, and except
         when otherwise indicated by the context, either the masculine or the
         neuter pronoun shall be deemed to include the masculine, the feminine,
         and the neuter, and the singular shall be deemed to include the
         plural.

16.3     REFERENCE TO THE CODE AND ERISA. Any reference to any section of the
         Internal Revenue Code, ERISA, or to any other statute or law shall be
         deemed to include any successor law of similar import.

16.4     GOVERNING LAW. The Plan and Trust shall be governed and construed in
         accordance with the laws of the state where the Trustee has its
         principal office if the Trustee is a corporation or an association,
         otherwise under the laws of the state where the Employer has its
         principal office.

16.5     COMPLIANCE WITH THE CODE AND ERISA. This Plan is intended to comply
         with all requirements for qualification under the Internal Revenue
         Code and ERISA, and if any provision hereof is subject to more than
         one interpretation or any term used herein is subject to more than one
         construction, such ambiguity shall be resolved in favor of that
         interpretation or construction which is consistent with the Plan being
         so qualified.  If any provision of the Plan is held invalid or
         unenforceable, such invalidity or unenforceability shall not affect
         any other provisions, and this Plan shall be construed and enforced as
         if such provision had not been included.

16.6     NON-ALIENATION. It is a condition of the Plan, and all rights of each
         Participant shall be subject thereto, that no right or interest of any
         Participant in the Plan shall be assignable or transferable in whole
         or in part, either directly or by operation of law or otherwise,
         including, but without limitation, execution, levy, garnishment,
         attachment, pledge, bankruptcy or in any other manner, and no right or
         interest of any Participant in the Plan shall be liable for or subject
         to any obligation or liability of such Participant. The preceding
         sentence shall not preclude the enforcement of a federal tax levy made
         pursuant to section 6331 of the Code or the collection by the United
         States on a judgement resulting from an unpaid tax assessment.

16.7     CONTRIBUTION RECAPTURE. Notwithstanding any other provisions of this
         Plan, (1) in the case of a contribution which is made by an Employer
         by a mistake of fact, Section 16.1 shall not prohibit the return of
         such contribution to the Employer within one year after the payment of
         the contribution, and (2) if a contribution is conditioned upon the
         deductibility of the contribution under section 404 of the Code, then,
         to the extent the deduction is disallowed, Section 16.1 shall not
         prohibit the return to the Employer of such contribution (to the
         extent disallowed) within one year after the disallowance of the
         deduction. The amount which may be returned to the Employer is the
         excess of (1) the amount contributed over (2) the amount that would
         have been contributed had there not occurred a mistake of fact or a
         mistake in determining the deduction. Earnings attributable to the
         excess contribution may not be returned to the Employer, but losses
         attributable thereto must reduce the amount to be so returned.
         Furthermore, if the withdrawal of the amount attributable to the
         mistaken contribution would cause the balance of the individual
         account of any





                                       66
<PAGE>   69
         Participant to be reduced to less than the balance which would have
         been in the account had the mistaken amount not been contributed, then
         the amount to be returned to the Employer would have to be limited so
         as to avoid such reduction.

16.8     QUALIFIED DOMESTIC RELATIONS ORDERS. Notwithstanding any other
         provisions of this Plan, the Participant's Account may be segregated
         and distributed pursuant to a Qualified Domestic Relations Order
         within the meaning of Internal Revenue Code section 414(p). The Plan
         Administrator shall establish procedures for determining if a Domestic
         Relations Order is qualified within the meaning of section 414(p).

                                 ARTICLE XVI-A
                              TOP-HEAVY PROVISIONS


16A.1    DEFINITIONS. The following definitions are atypical terms used only in
         this Article XVI-A.

         (A)     Compensation. The term Compensation, whenever used in this
                 Article XVI-A, means Compensation as defined in Article V of
                 the Plan, but includes the amount of any elective
                 contributions made by the Employer on the Employee's behalf to
                 a cafeteria plan established in accordance with the provisions
                 of Code section 125, a qualified cash or deferred arrangement
                 in accordance with the provisions of Code section 402(e)(3), a
                 simplified employee pension plan in accordance with the
                 provisions of Code section 402(h), or a tax sheltered annuity
                 plan maintained in accordance with the provisions of Code
                 section 403(b).

         (B)     Key Employee. The term Key Employee means any Employee or
                 former Employee (including deceased Employees) of the Employer
                 who at any time during the Plan Year or the four preceding
                 Plan Years was:

                 (1)      An officer of the Employer, but in no event if there
                          are more than 500 Employees, shall more than 50
                          Employees be considered Key Employees. If there are
                          less than 500 Employees, in no event shall the
                          greater of three Employees or 10% of all Employees,
                          be taken into account under this Subsection as Key
                          Employees. If the number of officers is limited by
                          the terms of the preceding sentence, the Employees
                          with the highest Compensation will be considered to
                          be officers.

                          In no event shall an officer whose annual
                          Compensation is less than 50% of the dollar
                          limitation in effect under Code section 415(b)(1)(A)
                          as adjusted from time to time, be a Key Employee for
                          any such Plan Year.

                          In making a determination under this Subsection,
                          Employees who have not completed six months of
                          Service by the end of the applicable Plan Year,
                          Employees who normally work less than 17-1/2 hours
                          per week, Employees who normally work less than six
                          months during a year, Employees who have not attained
                          21, and nonresident aliens who receive no earned
                          income from U.S. sources, shall be excluded.

                          Also excluded under the above paragraph are Employees
                          who are covered by an agreement which the Secretary
                          of Labor finds to be a collective bargaining
                          agreement. Such Employees will be excluded only if
                          retirement benefits were the subject of good faith
                          bargaining, 90% of the Employees of the Employer are
                          covered by the agreement, and the Plan covers only
                          Employees who are not covered by the agreement.

                 (2)      One of the 10 Employees who has annual Compensation
                          greater than the amount in effect under Internal
                          Revenue Code section 415(c)(1)(A) and who owns (or is
                          considered to own within the meaning of Internal
                          Revenue Code section 318, as modified by section
                          416(i)(1)(B)(iii)) both more than 1/2% interest and
                          the largest interest in the Employer. If two or more
                          Employees own equal interests in the Employer, the
                          ranking of ownership share will be in descending
                          order of such Employees' Compensation. If the
                          Employer is other than a corporation, the term
                          "interest" as used herein shall refer to capital or
                          profits


                                       68
<PAGE>   71
                          interest.

                 (3)      An Employee who owns (or is considered to own within
                          the meaning of Internal Revenue Code section 318, as
                          modified by section 416(i)(1)(B)(iii)) more than 5%
                          of the outstanding stock of the Employer or stock
                          possessing more than 5% of the total combined voting
                          power of all stock of the Employer. If the Employer
                          is other than a corporation, an Employee who owns, or
                          is considered to own, more than 5% of the capital or
                          profits interest in the Employer. The determination
                          of 5% ownership shall be made separately for each
                          member of a controlled group of corporations (as
                          defined in Code section 414(b)), or of a group of
                          trades or businesses (whether or not incorporated)
                          that are under common control (as defined in Code
                          section 414(c)), or of an affiliated service group
                          (as defined in Code section 414(m)).

                 (4)      An Employee who owns (or is considered to own within
                          the meaning of Internal Revenue Code section 318, as
                          modified by section 416(i)(1)(B)(iii)) more than 1%
                          of the outstanding stock of the Employer or stock
                          possessing more than 1% of the total combined voting
                          power of all stock of the Employer, and whose annual
                          Compensation is more than $150,000. If the Employer
                          is other than a corporation, an Employee who owns, or
                          is considered to own, more than 1% of the capital or
                          profits interest in the Employer, and whose annual
                          Compensation is more than $150,000.

                 For the purposes of paragraphs (2), (3) and (4) above, if an
                 Employee's ownership interest changes during a given Plan
                 Year, his ownership interest for that Plan Year is the largest
                 interest owned at any time during the Plan Year.

                 The Beneficiary of any deceased Employee who was a Key
                 Employee shall be considered a Key Employee for the same
                 period as the deceased Employee would have been so considered.

         (C)     Non-Key Employee. The term Non-Key Employee means any Employee
                 or former Employee of the Employer who is not a Key Employee.
                 The Beneficiary of any deceased Employee who is a Non-Key
                 Employee shall be considered a Non-Key Employee for the same
                 period as the deceased Employee would have been so considered.

         (D)     Determination Date. The term Determination Date means, with
                 respect to a Plan Year, the last day of the preceding Plan
                 Year, or, in the case of the first Plan Year of a plan, the
                 last day of the first Plan Year.

         (E)     Valuation Date. The term Valuation Date means, with respect to
                 a Plan Year, the last day of the preceding Plan Year and is
                 the date on which Account Balances are valued for the purpose
                 of determining the Plan's Top-Heavy status.

         (F)     Account Balance. The term Account Balance means the value of
                 the Participant's Account standing to the credit of a
                 Participant, a former Participant, or the Beneficiary of a
                 former Participant, as the case may be, as of the Valuation
                 Date. Such Account Balance shall include any contributions due
                 as of the Determination Date and all distributions made to the
                 Participant (or former Participant or Beneficiary, as the case
                 may be) during the Plan Year or the preceding four Plan Years,
                 except for distributions of Related Rollovers. However, the
                 Account Balance shall not include any deductible Employee
                 Contributions made pursuant to Internal Revenue Code section
                 219 or Unrelated Rollovers made to the Plan after December 31,
                 1983.

                 A Related Rollover is a Rollover Contribution or Transfer that
                 either was not initiated by the





                                       69
<PAGE>   72
                 Employee or was made to a plan maintained by the same Employer.

                 An Unrelated Rollover is a Rollover Contribution or Transfer
                 that was initiated by the Employee and was made from a plan
                 maintained by one employer to a plan maintained by another
                 employer.

                 For purposes of this Subsection (F), the term Employer shall
                 include all employers that are required to be aggregated in
                 accordance with Internal Revenue Code sections 414(b), (c) or
                 (m).

         (G)     Required Aggregation Group. The term Required Aggregation
                 Group means all of the plans of the Employer which cover a Key
                 Employee, including any such plan maintained by the Employer
                 pursuant to the terms of a collective bargaining agreement,
                 and each other plan of the Employer which enables any plan in
                 which a Key Employee participates to satisfy the requirements
                 of Internal Revenue Code sections 401(a)(4) or 410.

         (H)     Permissive Aggregation Group. The term Permissive Aggregation
                 Group means all of the plans of the Employer which are
                 included in the Required Aggregation Group plus any plans of
                 the Employer which provide comparable benefits to the benefits
                 provided by the plans in the Required Aggregation Group and
                 are not included in the Required Aggregation Group, but which
                 satisfy the requirements of Internal Revenue Code sections
                 401(a)(4) and 410 when considered together with the Required
                 Aggregation Group, including any plan maintained by the
                 Employer pursuant to a collective bargaining agreement which
                 does not include a Key Employee.

         (I)     Top-Heavy Plan. The Plan is Top-Heavy if it meets the
                 requirements of Section 16A.2.

         (J)     Super Top-Heavy Plan. The Plan is Super Top-Heavy if it meets
                 the requirements of Section 16A.3.

         (K)     Terminated Plan. A plan shall be considered to be a 
                 Terminated Plan if it:

                 (1)      has been formally terminated;

                 (2)      has ceased crediting service for benefit accruals and
                          vesting; or

                 (3)      has been or is distributing all plan assets to
                          Participants (or Beneficiaries) as soon as
                          administratively possible.

                 With the exception of the Minimum Employer Contribution
                 Requirements and the Minimum Vesting Requirements, the
                 Top-Heavy provisions of this Article XVI-A will apply to any
                 Terminated Plan which was maintained at any time during the
                 five years ending on the Determination Date.

         (L)     Frozen Plan. A plan shall be considered to be a Frozen Plan if
                 all benefit accruals have ceased but all assets have not been
                 distributed to Participants or Beneficiaries. The Top-Heavy
                 provisions of this Article XVI-A will apply to any such Frozen
                 Plan.

16A.2    TOP-HEAVY PLAN STATUS. This Plan shall be determined to be Top-Heavy
         if, as of the Determination Date, the aggregate of the Account
         Balances of Key Employees exceeds 60% of the aggregate of the Account
         Balances of all Employees covered by the Plan. The determination of
         whether the Plan is Top-Heavy shall be made after aggregating all
         plans in the Required Aggregation Group, and after aggregating any
         other plans which are in the Permissive Aggregation Group, if such
         permissive aggregation thereby eliminates the Top-Heavy status of any
         plan within such Required Aggregation Group.





                                       70
<PAGE>   73
         In determining whether this Plan is Top-Heavy, the Account Balance of
         a former Key Employee who is now a Non-Key Employee will be
         disregarded. Likewise, for Plan Years beginning after December 31,
         1984, the Account Balance of any Employee who has not performed an
         Hour of Service during the five-year period ending on the
         Determination Date will be excluded.

16A.3    SUPER TOP-HEAVY PLAN STATUS. This Plan shall be determined to be Super
         Top-Heavy if, as of the Determination Date, the Plan would meet the
         test specified in Section 16A.2 above, if 90% were substituted for 60%
         in each place where it appears. The Plan may be permissively
         aggregated in order to avoid being Super Top-Heavy.

16A.4    TOP-HEAVY REQUIREMENTS. Notwithstanding anything in the Plan to the
         contrary, if the Plan is Top-Heavy with respect to any Plan Year
         beginning after December 31, 1983, then the Plan shall meet the
         following requirements for such Plan Year:

         (A)     Compensation Limit. The annual Compensation of each
                 Participant taken into account under the Plan shall not exceed
                 $150,000; however, such dollar limitation shall be adjusted to
                 take into account any adjustments made by the Secretary of the
                 Treasury or his delegate pursuant to Internal Revenue Code
                 section 416(d)(2).

         (B)     Minimum Employer Contribution Requirements. A Minimum Employer
                 Contribution of 3% of each Eligible Employee's Compensation
                 will be made on behalf of each Eligible Employee in the Plan.

                 If the actual Employer Contribution made or required to be
                 made for Key Employees is less than 3%, the Minimum Employer
                 Contribution required hereunder shall not exceed the
                 percentage contribution made for the Key Employee for whom the
                 percentage of Employer Contributions and Forfeitures relative
                 to the first $150,000 of Compensation is the highest for the
                 Plan Year after taking into account contributions or benefits
                 under other qualified plans in the Plan's Required Aggregation
                 Group.

                 However, if a Participant in this Plan is also a participant
                 in a defined benefit plan maintained by the Employer, such
                 Participant shall receive the Top-Heavy minimum benefit under
                 the defined benefit plan in lieu of the Minimum Employer
                 Contribution described herein. Such minimum benefit will be
                 equal to the Participant's average yearly Compensation during
                 his five highest-paid consecutive years, multiplied by the
                 lesser of 2% per Year of Service or 20%. Compensation periods
                 and Years of Service to be taken into account in the
                 calculation of this benefit shall be subject to any
                 limitations set forth in the defined benefit plan.

                 For any Limitation Year in which this Plan is Top-Heavy but
                 not Super Top-Heavy, the Minimum Employer Contribution shall
                 be increased to 4% of each Eligible Employee's Compensation in
                 order to preserve the use of the factor 1.25 in the
                 denominators of the fractions described in Section 5.4 (B) (1)
                 and Section 5.4 (D) (1). A Participant who receives the
                 Top-Heavy minimum benefit in lieu of the Minimum Employer
                 Contribution shall receive an increased minimum benefit equal
                 to the Participant's average yearly Compensation during his
                 five highest-paid consecutive years, multiplied by the lesser
                 of 3% per Year of Service or 20% plus one percentage point (to
                 a maximum of 10 percentage points) for each year that this
                 Plan is maintained. Compensation periods and Years of Service
                 to be taken into account in the calculation of this increased
                 minimum benefit shall be subject to any limitations set forth
                 in the defined benefit plan.

                 For any Limitation Year in which this Plan is Super Top-Heavy,
                 the factor of 1.25 in the denominators of the fractions
                 described in Sections 5.4 (B) (1)  and 5.4 (D) (1)  shall be
                 reduced





                                       71
<PAGE>   74
                 to 1.0. The Minimum Employer Contribution payable in such 
                 years shall be 3% of each Eligible Employee's Compensation 
                 and the defined benefit Top-Heavy minimum benefit shall be 
                 average Compensation multiplied by the lesser of 2% per Year 
                 of Service or 20%.

                 Eligible Employees are all Non-Key Employees who are
                 Participants in the Plan as of the last day of the Plan Year
                 regardless of whether they had completed 1,000 Hours of
                 Service during the Plan Year. Also included are Non-Key
                 Employees who would have been Participants as of the last day
                 of the Plan Year except:

                 .        The Employee's Compensation was below a required 
                          minimum level; or

                 .        The Employee chose not to make Elective Deferral
                          Contributions when he was eligible to do so.

                 Elective Deferral Contributions and Matching Contributions
                 made to Key Employees shall be taken into account as Employer
                 Contributions allocated to such Key Employees when determining
                 whether a lower Minimum Employer Contribution is permissible
                 for purposes of this section. However, Elective Deferral
                 Contributions made by Non-Key Employees shall not be used
                 towards satisfying the Minimum Employer Contribution required
                 to be allocated to Non-Key Employees pursuant to this section.

                 Matching Contributions made on behalf of Non-Key Employees
                 may, at the option of the Employer, be used to satisfy the
                 Minimum Employer Contribution requirement. However, for Plan
                 Years beginning after December 31, 1988,  to the extent that
                 Matching Contributions are used for this purpose, they shall
                 not be used to satisfy the Actual Contribution Percentage
                 Test.

         (C)     Minimum Vesting Requirements. Vesting shall continue to be
                 determined in accordance with the schedule in Article I of
                 this Plan if this Plan is determined to be Top Heavy.

                                  ARTICLE XVII
                                TRUST AGREEMENT



17.1     CREATION AND ACCEPTANCE OF TRUST. The Trustee, by joining in the
         execution of the Plan and trust agreement, accepts the Trust hereby
         created and agrees to act in accordance with the express terms and
         conditions herein stated.

17.2     TRUSTEE CAPACITY; CO-TRUSTEES. The Trustee may be a bank, trust
         company or other corporation possessing trust powers under applicable
         state or federal law or one or more individuals or any combination
         thereof.

         When two or more persons serve as Trustee, they are specifically
         authorized, by a written agreement between themselves, to allocate
         specific responsibilities, obligations or duties among themselves. An
         original copy of such written agreement is to be delivered to the
         Administrator.

17.3     RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR TRUSTEE. Any Trustee
         may resign at any time by delivering to the Administrator a written
         notice of resignation, to take effect at a date specified therein,
         which shall not be less than 30 days after the delivery thereof,
         unless such notice shall be waived.

         The Trustee may be removed with or without cause by the Board of
         Directors by delivery of a written notice of removal, to take effect
         at a date specified therein, which shall not be less than 30 days
         after delivery thereof, unless such notice shall be waived.

         In the case of the resignation or removal of a Trustee, the Trustee
         shall have the right to a settlement of its account, which may be
         made, at the option of the Trustee, either (1) by judicial settlement
         in an action instituted by the Trustee in a court of competent
         jurisdiction, or (2) by written agreement of settlement between the
         Trustee and the Administrator.

         Upon such settlement, all right, title and interest of such Trustee in
         the assets of the Trust and all rights and privileges under this
         Agreement theretofore vested in such Trustee shall vest in the
         successor Trustee, and thereupon all future liability of such Trustee
         shall terminate; provided, however, that the Trustee shall execute,
         acknowledge and deliver all documents and written instruments which
         are necessary to transfer and convey the right, title and interest in
         the Trust assets, and all rights and privileges to the successor
         Trustee.

         The Board of Directors, upon receipt of notice of the resignation or
         removal of the Trustee, shall promptly designate a successor Trustee,
         whose appointment is subject to acceptance of this Trust in writing
         and shall notify in writing the insurance company of such successor
         Trustee.

17.4     TAXES, EXPENSES AND COMPENSATION OF TRUSTEE. The Trustee shall deduct
         from and charge against the Trust fund any taxes paid by it which may
         be imposed upon the Trust fund or the income thereof or which the
         Trustee is required to pay with respect to the interest of any person
         therein.

         The Trustee shall be paid such reasonable compensation as shall from
         time to time be agreed upon in writing by the Employer and the
         Trustee. An individual serving as Trustee who already receives
         full-time pay from the Employer shall not receive compensation from
         the Plan. In addition, the Trustee shall be





                                       73
<PAGE>   76
         reimbursed for any reasonable expenses, including reasonable counsel
         fees incurred by it as Trustee. Such compensation and expenses shall
         be paid from the Trust fund unless paid or advanced by the Employer.

17.5     TRUSTEE ENTITLED TO CONSULTATION. The Trustee shall be entitled to
         advice of counsel, which may be counsel for the Plan or the Employer,
         in any case in which the Trustee shall deem such advice necessary.
         With the exception of those powers and duties specifically allocated
         to the Trustee by the express terms of this Plan, it shall not be the
         responsibility of the Trustee to interpret the terms of the Plan or
         Trust and the Trustee may request, and is entitled to receive guidance
         and written direction from the Administrator on any point requiring
         construction or interpretation of the Plan documents.

17.6     RIGHTS, POWERS AND DUTIES OF TRUSTEE. The Trustee shall have the
         following rights, powers, and duties:

         (A)     The Trustee shall be responsible for the safekeeping and
                 administering of the assets of this Plan and Trust in
                 accordance with the provisions of this Agreement and any
                 amendments thereto. The duties of the Trustee under this
                 Agreement shall be determined solely by the express provisions
                 of this Agreement and no further duties or responsibility
                 shall be implied. Subject to the terms of this Plan and Trust,
                 the Trustee shall be fully protected and shall incur no
                 liability in acting in reliance upon the written instructions
                 or directions of the Administrator or a duly designated
                 Investment Manager or any other Named Fiduciary.

         (B)     The Trustee shall have all powers necessary or convenient for
                 the orderly and efficient performance of its duties hereunder,
                 including but not limited to those specified in this section.
                 The Trustee may appoint one or more administrative agents or
                 contract for the performance of such administrative and
                 service functions as it may deem necessary for the effective
                 installation and operation of the Plan and Trust.

         (C)     The Trustee shall have the power to collect and receive any
                 and all monies and other property due hereunder and to give
                 full discharge and acquittance therefor; to settle, compromise
                 or submit to arbitration any claims, debits or damages due or
                 owing to or from the Trust; to commence or defend suits or
                 legal proceedings wherever, in its judgment, any interest of
                 the Trust requires it; and to represent the Trust in all suits
                 or legal proceedings in any court of law or equity or before
                 any other body or tribunal. It shall have the power generally
                 to do all acts, whether or not expressly authorized, which the
                 Trustee in the exercise of its Fiduciary responsibility may
                 deem necessary or desirable for the protection of the Trust
                 and the assets thereof.

         (D)     The Trustee may temporarily hold cash balances and shall be
                 entitled to deposit any such funds received in a bank account
                 or bank accounts in the name of the Trust in any bank or banks
                 selected by the Trustee, including the banking department of
                 the Trustee, pending disposition of such funds in accordance
                 with the Trust. Any such deposit may be made with or without
                 interest.

         (E)     The Trustee shall deal with any assets of this Trust held or
                 received under this Plan only in accordance with the written
                 directions from the Administrator. The Trustee shall be under
                 no duty to determine any facts or the propriety of any action
                 taken or omitted by it in good faith pursuant to instructions
                 from the Administrator.

         (F)     If the whole or any part of the Trust shall become liable for
                 the payment of any estate, inheritance, income or other tax
                 which the Trustee shall be required to pay, the Trustee shall
                 have full power and authority to pay such tax out of any
                 monies or other property in its hands for the account of the
                 person whose interest hereunder is so liable. Prior to making
                 any payment, the Trustee may require such releases or other
                 documents from any lawful taxing authority as it shall deem





                                       74
<PAGE>   77
                 necessary. The Trustee shall not be liable for any nonpayment 
                 of tax when it distributes an interest hereunder on 
                 instructions from the Administrator.

         (G)     The Trustee shall keep a full, accurate and detailed record of
                 all transactions of the Trust which the Administrator shall
                 have the right to examine at any time during the Trustee's
                 regular business hours.  Following the close of the fiscal
                 year of the Trust, or as soon as practical thereafter, the
                 Trustee shall furnish the Administrator with a statement of
                 account. This account shall set forth all receipts,
                 disbursements and other transactions effected by the Trustee
                 during said year.

                 The Administrator shall promptly notify the Trustee in writing
                 of its approval or disapproval of the account. The
                 Administrator's failure to disapprove the account within 60
                 days after receipt shall be considered an approval. The
                 approval by the Administrator shall be binding as to all
                 matters embraced in any statement to the same extent as if the
                 account of the Trustee had been settled by judgment or decree
                 of a court of competent jurisdiction under which the Trustee,
                 Administrator, Employer and all persons having or claiming any
                 interest in the Trust were parties; provided, however, that
                 the Trustee may have its account judicially settled if it so
                 desires.

         (H)     If, at any time, there shall be a dispute as to the person to
                 whom payment or delivery of monies or property should be made
                 by the Trustee, or regarding any action to be taken by the
                 Trustee, the Trustee may postpone such payment, delivery or
                 action, retaining the funds or property involved, until such
                 dispute shall have been resolved in a court of competent
                 jurisdiction or the Trustee shall have been indemnified to its
                 satisfaction or until it has received written direction from
                 the Administrator.

         (I)     Anything in this instrument to the contrary notwithstanding,
                 it shall be understood that the Trustee shall have no duty or
                 responsibility with respect to the determination of matters
                 pertaining to the eligibility of any Employee to become or
                 remain a Participant hereunder, the amount of benefit to which
                 any Participant or Beneficiary shall be entitled hereunder,
                 all such responsibilities being vested in the Administrator.
                 The Trustee shall have no duty to collect any contribution
                 from the Employer and shall not be concerned with the amount
                 of any contribution nor the application of the contribution
                 formula.

17.7     EVIDENCE OF TRUSTEE ACTION. In the event that the Trustee is comprised
         of two or more Trustees, then those Trustees may designate one such
         Trustee to transmit all decisions of the Trustee and to sign all
         necessary notices and other reports on behalf of the Trustee. All
         notices and other reports bearing the signature of the individual
         Trustee so designated shall be deemed to bear the signatures of all
         the individual Trustees and all parties dealing with the Trustee are
         entitled to rely on any such notices and other reports as authentic
         and as representing the action of the Trustee.

17.8     INVESTMENT POLICY. This Plan has been established for the sole purpose
         of providing benefits to the Participants and their Beneficiaries. In
         determining its investments hereunder, the Trustee shall take account
         of the advice provided by the Administrator as to funding policy and
         the short and long range needs of the Plan based on the evident and
         probable requirements of the Plan as to the time benefits shall be
         payable and the requirements therefor.

17.9     PERIOD OF TRUST. If it shall be determined that the applicable state
         law requires a limitation on the period during which the Employer's
         Trust shall continue, then such Trust shall not continue for a period
         longer than 21 years following the death of the last of those
         Participants including future Participants who are living at the
         effective date hereof. At least 180 days prior to the end of the
         twenty-first year as described in the first sentence of this Section,
         the Employer, the Administrator and the Trustee shall provide for the
         establishment of a successor trust and transfer of Plan assets to the
         successor trustee. If the





                                       75
<PAGE>   78
         applicable state law requires no such limitation, then this Section
         shall not be operative.

IN WITNESS WHEREOF, the Employer, the Administrator, and the Trustees have
hereunto affixed their signatures.

                          SERV-TECH, INC. CONSOLIDATED

herein, by and between Serv-Tech, Inc. (hereinafter sometimes called

Perrone (hereinafter sometimes collectively called "Trustee") of Houston,
Texas:

                                  WITNESSETH:

         WHEREAS, the Corporation previously adopted the Serv-Tech, Inc.
Employee 401(k) Retirement Plan for the sole and exclusive benefit of its
Employees and their Beneficiaries, effective January 1, 1990; and

         WHEREAS, on January 1, 1993, the Corporation merged the Serv-Tech, Inc.

the Talbert & Associates, Inc. Savings Plan and Trust, resulting in the current
Plan, effective January 1, 1993; and

         WHEREAS, the Corporation through the action of its Board of Directors,

amended.

         - One Year of Service (as defined in section 2.6)

         - Participant reaches the Age of 21.

         Article IV, Section 4.2 of the Plan is amended by replacing the

         a Salary Deferral Agreement, up to a maximum of 6% of his
         compensation, subject to the Limitations on Allocations specified in

<PAGE>   82

         The Plan is further amended by adding the following new Article XVIII,
with Sections 18.1, 18.2, 18.3, 18.4, 18.5, 18.6, 18.7, and 18.8:

                                 ARTICLE XIII.
                             LOANS TO PARTICIPANTS

18.1     APPLICATION AND LIMITATION. Upon the written application of any
         Participant, the Plan Administrator, in accordance with its uniform,
         nondiscriminatory policy and its written loan program, may make a loan
         or loans to such Participant. If the Participant is married at the
         time of the application, written spousal consent regarding the amount
         of the loan and the possible reduction of the Participant's Account
         balance as a result of default shall be obtained within the ninety
         (90) day period ending on the date the loan is made, and such consent
         shall meet requirements comparable to those set forth in Section
         417(a)(2) of the Code. The preceding sentence shall not apply if the
         Plan Administrator does not have actual knowledge of such marriage or
         the Participant reasonably demonstrates that the whereabouts of his
         spouse is unknown.

         The aggregate amount of all such loans to any Participant shall not
         exceed the lesser of:

                     (a)     $50,000, or

                     (b)     one-half (1/2) of the vested amount in the 
                     Participant's Account,

         as further limited under Article XVIII, Section 18.2, unless the
         Participant receiving a loan which exceeds said limitations and the
         Plan Administrator agree in writing to make such a loan, and further
         agree that the Participant shall be responsible for the payment of any
         taxes incurred by virtue of such loan. For purposes of computing (i)
         the aggregate amount of all loans to any Participant, and (ii) the
         amount in the Participant's Account with respect to Section 72(p) of
         the Code, and for all other purposes of this Article XV with respect
         to Section 72(p) of the Code, this Plan and all other plans maintained
         by the Employer, any Affiliated Company, or any other related
         organization described in Sections 414(b), 414(c) and 414(m) of the
         Code shall be aggregated and treated as one plan. The amount in the
         Participant's Account will be computed by the Trustee at the time of
         any such loan, and will include those amounts received from an
         Individual Retirement Account ("IRA") or other qualified plan. The
         term loan includes any amount received as a loan under a contract
         purchased by the Plan, such as a life insurance policy, and any
         assignment or pledge with respect to such contract.
<PAGE>   83

18.2     PURPOSES OF LOANS. Loans shall be made under the provisions of this
         Article XVIII for any legal purpose except for the purpose of
         purchasing registered securities. The authority herein granted to the
         Trustee to approve such loans from the Trust is for the purpose
         described above and shall not be used as a means of distributing
         benefits before they otherwise become due.

18.3     TERMS. All loans to Plan Participants granted under this provision
         shall be treated as a segregated investment of the Trust and shall be
         evidenced by the Participant's promissory note payable to the order of
         the Trustee.  The Plan Administrator shall have the right to make any
         reasonable interpretations to implement the rate of interest charged
         and shall have the right to modify such interpretations upon proper
         notice with respect to all future loans. Such loans shall bear simple
         interest at two percentage point (2.0%) over the prime rate being
         charged at that time for loans to commercial borrowers by a major bank
         in Harris County, Texas designated by the Plan Administrator, but in
         no case shall the Participant pay more than the maximum legal rate of
         interest. The terms of any loan shall be arrived at by mutual
         agreement between the Plan Administrator and the Participant pursuant
         to a uniform, nondiscriminatory policy. The specified maturity date,
         including extensions, renewals, renegotiations, or revisions, shall
         not be later than the earlier of (a) the Participant's Normal
         Retirement Age (or the date of termination of employment, if earlier),
         or (b) either five (5) years measured from the date the loan is made
         by the Trustee, or, in the event of a home loan as described in
         Section 18.4, ten (10) years measured from the date such home loan is
         made or such other reasonable period of time as determined under the
         Code. However, a Participant may request a loan with a maturity date
         later than the above dates provided he agrees, in writing, to be
         responsible for the payment of any taxes incurred by virtue of such
         maturity date. Any loan granted under the terms of this Article XVIII
         shall be repaid on an installment basis, with substantially equal
         determinable periodic payments of principal and interest, not less
         often than quarterly. Loan repayments may only be made through payroll
         deduction. Notwithstanding the previous sentence, prepayment of the
         Participant's loan balance my be made in full using the Participant's
         personal check. The borrowing Participant's Account shall serve as
         security for any such loan and the same shall be provided in the
         promissory note made by the Participant. Every loan applicant shall
         receive a clear statement of the charges involved in each loan
         transaction. This statement shall include the dollar amount and annual
         interest rate of the finance charge.

18.4     HOME LOANS. A home loan is any loan used to acquire any dwelling unit
         (including, but not limited to, a house, apartment, condominium, or
         mobile home not used on a
<PAGE>   84

         transient basis) which within a reasonable time is to be used
         (determined at the time the loan is made) as the principal residence
         of the Participant.

18.5     RECOURSE; PROHIBITION AGAINST DISTRIBUTIONS WHILE LOAN OUTSTANDING.
         No payment out of the Trust shall ever be made to any Participant,
         Beneficiary, or other individual or entity under this Plan unless and
         until all unpaid loans to such Participant, and interest thereon,
         shall have been satisfied in full. In the event a note is not paid as
         and when due, the Plan Administrator (or Trustee) may, in addition and
         without resort to such other remedies as it may have under the law,
         give written notice to the Participant sent to his last known address.
         If the note is not paid within thirty (30) days from the date of such
         notice, the amount standing to the credit of the Participant's Account
         in the Trust will be charged with, but not actually reduced by, the
         amount of the unpaid balance of the loan, together with the interest
         thereon, and the Participant's indebtedness shall thereupon be
         discharged. The amount of the unpaid balance of the loan and interest
         thereon which is charged to the Participant's Account shall be reduced
         by any subsequent payments of principal and, if appropriate, interest.
         The Plan Administrator (or Trustee) shall then send a written notice
         to the Participant at his last known address which confirms the amount
         the Participant must include in his income as a distribution from the
         Plan. At the time an event requiring a distribution from the Trust
         occurs, such as death, disability, retirement or termination of
         employment, such amount charged to the Participant's Account will be
         applied to reduce the Participant's interest in such Account, and the
         Participant's indebtedness shall thereupon be discharged and the loan
         principal and any interest thereon shall be deemed to be satisfied in
         full. If an event normally requiring a distribution, as described
         above, occurs before any loan is repaid in full, the unpaid balance
         thereof, together with the interest thereon, shall become due and
         payable and the Trustee shall first satisfy the indebtedness from the
         amount in the Participant's Account before making any payments to the
         Participant, or to such other individual or entity as determined under
         this Plan.

18.6     TREATMENT OF LOAN PROCEEDS. A loan to a Participant shall be
         considered as an investment of such Participants's Account. The amount
         the Participant has invested in the other classes of investments shall
         be reduced proportionately to reflect his reduced Account balance,
         unless the Participant requests, in writing, a different allocation of
         the reduction in his investments. Expenses incurred by the Plan in
         processing a Participant's loan may on a uniform basis in the
         discretion of the Trustee be charged against the proceeds of such
         loan.
<PAGE>   85

18.7     EFFECT ON RIGHT TO PARTICIPATE IN PLAN. Unless such Participant leaves
         the employ of the Employer or withdraws from the Plan temporarily or
         permanently, such Participant shall remain a Participant in good
         standing and shall continue to participate in the Plan.

18.8     MINIMUM LOAN AMOUNTS. Not withstanding any other provision of this
         Plan, no Participant shall be eligible for a loan under the provisions
         of this Article XVIII unless the amount of such loan exceeds the
         minimum limit uniformly prescribed by the Plan Administrator, which in
         no event may exceed one thousand dollars ($1,000.00).

IN WITNESS WHEREOF, the Corporation and the Trustee have caused this First
Amendment to be executed on this 15th day of December 1994, to be effective 
as of January 1, 1995.
