            The Registrant hereby undertakes to submit the Plan, and any
amendments thereto, to the Internal Revenue Service ("IRS") in a timely manner
and will make all changes required by the IRS in order to qualify the Plan.

            As permitted by Item 601(b)(4)(iii)(A) of Regulation S-K, the
Registrant has not filed with this Registration Statement certain instruments
defining the rights of holders of long-term debt of the Registrant and its
subsidiaries because the total amount of securities authorized under any of
such instruments does not exceed 10% of the total assets of the Registrant and
its subsidiaries on a consolidated basis. The Registrant agrees to furnish a
copy of any such agreements to the Securities and Exchange Commission upon
request.


ITEM 9.     UNDERTAKINGS.

            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 this Registration Statement (or the most recent
post-effective amendment hereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in this
Registration Statement.  Notwithstanding the foregoing, any increase or
decrease in volume of securities offered (if the total dollar volume of
securities offered would not exceed that which was registered) and any
deviation from the low or high end of the estimated maximum offering range may
be reflected in the form of prospectus filed with the Securities and Exchange
Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume
and price represent no more than a 20% change in the maximum aggregate offering
price set forth in the "Calculation of Registration Fee" table in the effective
registration statement; and

            (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 this Registration Statement;

            Provided, however, that paragraphs (1)(i) and (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 with or furnished to
the Securities and Exchange Commission by the Registrant pursuant to Section 13
or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated
by reference in this 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 herein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.





                                      II-4


<PAGE>   5

            (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.

            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 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 this Registration Statement shall be
deemed to be a new registration statement relating to the securities offered
herein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

            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 Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act of 1933 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 Securities Act of 1933 and will be governed by the final
adjudication of such issue.

         EIGHTH:      Meetings of stockholders may be held outside the State of

         TENTH:       Whenever a compromise or arrangement is proposed between
this corporation and its creditors or any class of them and/or between this
corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of this corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for this corporation under
the provisions of section 291 of Title 8 of the Delaware Code or on the
application of trustees in dissolution or of any receiver or receivers
appointed for this corporation under the provisions of section 279 of Title 8
of the Delaware Code order a meeting of the creditors or class of creditors,
and/or of the stockholders or class of stockholders of this corporation, as the
case may be, to be summoned in such manner as the said court directs.  If a
majority in number representing three-fourths in value of the creditors or

Directors caused by resignation, removal, death, or other incapacity and any
newly created directorships resulting from an increase in the number of
directors shall be filled by a majority vote of the directors then in office,
whether or not a quorum.  Each director chosen to fill a vacancy shall hold
office for the unexpired term in respect of which such vacancy occurred.  Each
director chosen to fill a newly created directorship shall hold office until
the next election of the class for which such director shall have been chosen.
When the number of directors is changed, any newly created directorships





                                      -6-
<PAGE>   8
or any decreases in directorships shall be so apportioned among the classes as
to make all classes as nearly equal in number as possible.

         Any director may be removed from office as a director at any time, but
only for cause, by the affirmative vote of stockholders of record holding a
majority of the outstanding shares of stock of the corporation entitled to vote
in elections of directors at a meeting of the stockholders called for that
purpose.

         TWELFTH:     (A) Except as set forth in paragraph (B) of this Article,

         (1)          to adopt any agreement for, or to approve, the merger or
                      consolidation of the Corporation or any subsidiary (as

                      Corporation or any subsidiary, or

         (3)          to authorize the issuance or transfer by the Corporation
                      or any subsidiary of any voting securities of the
                      Corporation or any subsidiary in exchange or payment for
                      the securities or assets of any other person, if such
                      authorization is otherwise required by law or by any
                      agreement between the Corporation and any national
                      securities exchange or by any other agreement to which
                      the Corporation or any subsidiary is a party, if, in any
                      such case, as of the record date for the determination of
                      stockholders entitled to notice thereof and to vote
                      thereon or consent thereto, such other person is, or at
                      any time within the preceding twelve months has been, the
                      beneficial owner (as hereinafter defined) of 5 percent or
                      more of the outstanding shares of stock of the
                      Corporation entitled to vote in elections of directors.
                      If such other person is not, and has not been a 5 percent
                      beneficial owner, the provisions of this paragraph (A)
                      shall not apply, the provisions of Delaware law shall
                      apply.

         (B)          The provisions of paragraph (A) of this Article shall not
apply, and the provisions of Delaware law shall apply, to (1) any transaction
described therein if the Board of Directors by resolution shall have approved a
memorandum of understanding with such other person setting forth the principal
terms of such transaction and such transaction is substantially consistent

         such specified person or any corporation which controls or is
         controlled by such specified person.

         (E)          For purposes of determining whether a person owns

         character referred to in paragraph (B) of this Article.

         Any such determination shall be conclusive and binding for all
purposes of this Article.

                      of a share of such stock as determined by the Board in
                      good faith, which determination shall include
                      consideration of the highest closing price, or, in the
                      event there is no closing price, the highest closing bid
                      in the primary market in which such stock is traded
                      during the 90-day period preceding the date in question;
                      and (ii) in the case of property other than cash or
                      stock, the fair market value of such property on the date
                      in question as determined by the Board in good faith;

                      who is recommended to succeed a Continuing Director by a
                      majority of the then Continuing Directors.

         (D)          A majority of the total number of Continuing Directors

directors.

         SIXTEENTH:   (A)         The power to adopt, alter, amend or repeal

                                   EXHIBIT A


         RESOLVED, that pursuant to the authority vested in the Board of
Directors of this Corporation in accordance with the provisions of its
Certificate of Incorporation, a series of Preferred Stock, no par value, of the
Corporation be and it hereby is created, and that the designation and amount
thereof and the powers, preferences and relative, participating, optional and
other special rights of the shares of such series, and the qualifications,
limitations or restrictions thereof are as follows:

         Section 1.       Designation and Amount.  The shares of such series
shall be designated as "Series A Junior Participating Preferred Stock", which
shall have no par value, and the number of shares constituting such series
shall be 150,000.  Such number of shares may be increased or decreased by
resolution of the Board of Directors; provided, that no decrease shall reduce
the number of shares of Series A Junior Participating Preferred Stock to a
number less than that of the shares then outstanding plus the number of shares
issuable upon exercise of outstanding rights, options or warrants or upon
conversion of outstanding securities issued by the Corporation.

         Section 2.       Dividends and Distributions.

         (A)     Subject to the prior and superior rights of the holders of any
shares of any series of Preferred Stock ranking prior and superior to the
shares of Series A Junior Participating Preferred Stock with respect to
dividends, the holders of shares of Series A Junior Participating Preferred
Stock, in preference to the holders of shares of Common Stock, par value $0.50
per share (the "Common Stock"), of the Corporation and any other junior stock,
shall be entitled to receive, when, as and if declared by the Board of
Directors out of funds legally available for the purpose, quarterly dividends
payable in cash on the first day of March, June, September and December in each
year (each such date being referred to herein as a "Quarterly Dividend Payment
Date"), commencing on the first Quarterly Dividend Payment Date after the first
issuance of a share or fraction of a share of Series A Junior Participating
Preferred Stock in an amount per share (rounded to the nearest cent) equal to
the greater of (a) $1.00, or (b) subject to the provision for adjustment
hereinafter set forth, 100 times the aggregate per share amount of all cash
dividends, and 100 times the aggregate per share amount (payable in kind) of
all non-cash dividends or other distributions other than a dividend payable in
shares of Common Stock or a subdivision of the outstanding shares of Common
Stock (by reclassification or otherwise), declared on the Common Stock, since
the immediately preceding Quarterly Dividend Payment Date, or, with respect to
the first Quarterly Dividend Payment Date, since the first issuance of any
share or fraction of a share of Series A Junior Participating Preferred Stock.
In the event the Corporation shall at any time after August 28, 1986 (the
"Rights Declaration Date") (i) declare any dividend on Common Stock payable in
shares of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii)
combine the outstanding Common Stock into a smaller number of shares, then in
each such case the amount to which holders of shares of Series A Junior
Participating Preferred Stock were entitled immediately prior to such event
under clause (b) of the preceding sentence shall be adjusted by multiplying
such amount by a fraction the numerator of which is the number of shares of
Common Stock outstanding immediately after such event and the denominator of
which is the number of shares of Common Stock that were outstanding immediately
prior to such event.





                                      A-1
<PAGE>   18
         (B)     The Corporation shall declare a dividend or distribution on
the Series A Junior Participating Preferred Stock as provided in paragraph (A)
above immediately after it declares a dividend or distribution on the Common
Stock (other than a dividend payable in shares of Common Stock); provided that,
in the event no dividend or distribution shall have been declared on the Common
Stock during the period between any Quarterly Dividend Payment Date and the
next subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per share
on the Series A Junior Participating Preferred Stock shall nevertheless be
payable on such subsequent Quarterly Dividend Payment Date.

         (C)     Dividends shall begin to accrue and be cumulative on
outstanding shares of Series A Junior Participating Preferred Stock from the
Quarterly Dividend Payment Date next preceding the date of issue of such shares
of Series A Junior Participating Preferred Stock unless the date of issue of
such shares is prior to the record date for the first Quarterly Dividend
Payment Date, in which case dividends on such shares shall begin to accrue from
the date of issue of such shares, or unless the date of issue is a Quarterly
Dividend Payment Date or is a date after the record date for the determination
of holders of shares of Series A Junior Participating Preferred Stock entitled
to receive a quarterly dividend and before such Quarterly Dividend Payment Date
in either of which events such dividends shall begin to accrue and be
cumulative from such Quarterly Dividend Payment Date.  Accrued but unpaid
dividends shall not bear interest.  Dividends paid on the shares of Series A
Junior Participating Preferred Stock in an amount less than the total amount of
such dividends at the time accrued and payable on such shares shall be
allocated pro rata on a share-by- share basis among all such shares at the time
outstanding.  The Board of Directors may fix a record date for the
determination of holders of shares of Series A Junior Participating Preferred
Stock entitled to receive payment of a dividend or distribution declared
thereon, which record date shall be no more than 30 days prior to the date
fixed for the payment thereof.

         Section 3.       Voting Rights.   The holders of shares of Series A
Junior Participating Preferred Stock shall have the following voting rights:

         (A)     Each share of Series A Junior Participating Preferred Stock
shall entitle the holder thereof to one vote on all matters submitted to a vote
of the stockholders of the Corporation.

         (B)     Except as otherwise provided herein or by law, the holders of
shares of Series A Junior Participating Preferred Stock and the holders of
shares of Common Stock shall vote together as one class on all matters
submitted to a vote of shareholders of the Corporation.

         (C)     (i)      If at any time dividends on any Series A Junior
Participating Preferred Stock shall be in arrears in an amount equal to six (6)
quarterly dividends thereon, the occurrence of such contingency shall mark the
beginning of a period (herein called a "default period") which shall extend
until such time when all accrued and unpaid dividends for all previous
quarterly dividend periods and for the current quarterly dividend period on all
shares of Series A Junior Participating Preferred Stock then outstanding shall
have been declared and paid or set apart for payment.  During each default
period, the holders of the Series A Junior Participating Preferred Stock,
voting as a class together with the holders, if any, of other series of
Preferred Stock having the right to vote upon a default in the payment of
dividends, irrespective of series, shall have the right to elect two (2)
Directors.





                                      A-2
<PAGE>   19
                 (ii)     During any default period, such voting right of the
holders of Series A Junior Participating Preferred Stock may be exercised
initially at a special meeting called pursuant to subparagraph (iii) of this
Section 3(C) or at any annual meeting of stockholders, and thereafter at annual
meetings of stockholders, provided that neither such voting right nor the right
of the holders of any other series of Preferred Stock, if any, to increase, in
certain cases, the authorized number of Directors shall be exercised unless the
holders of ten percent (10%) in number of shares of Preferred Stock outstanding
shall be present in person or by proxy.  The absence of a quorum of the holders
of Common Stock shall not affect the exercise by the holders of Preferred Stock
of such voting right.  At any meeting at which the holders of Preferred Stock
shall exercise such voting right initially during an existing default period,
they shall have the right, voting as a class, to elect Directors to fill such
vacancies, if any, in the Board of Directors as may then exist up to two (2)
Directors or, if such right is exercised at an annual meeting, to elect two (2)
Directors.  If the number which may be so elected at any special meeting does
not amount to the required number, the holders of the Preferred Stock shall
have the right to make such increase in the number of Directors as shall be
necessary to permit the election by them of the required number.  After the
holders of the Preferred Stock shall have exercised their right to elect
Directors in any default period and during the continuance of such period, the
number of Directors shall not be increased or decreased except by vote of the
holders of Preferred Stock as herein provided or pursuant to the rights of any
equity securities ranking senior to or pari passu with the Series A Junior
Participating Preferred Stock.

                 (iii)    Unless the holders of Preferred Stock shall, during
an existing default period, have previously exercised their right to elect
Directors, the Board of Directors may order, or any stockholder or stockholders
owning in the aggregate not less than ten percent (10%) of the total number of
shares of Preferred Stock outstanding, irrespective of series, may request, the
calling of a special meeting of the holders of Preferred Stock, which meeting
shall thereupon be called by the President, a Vice-President or the Corporate
Secretary of the Corporation.  Notice of such meeting and of any annual meeting
at which holders of Preferred Stock are entitled to vote pursuant to this
paragraph (C)(iii) shall be given to each holder of record of Preferred Stock
by mailing a copy of such notice to him at his last address as the same appears
on the books of the Corporation.  Such meeting shall be called for a time not
earlier than 20 days and not later than 60 days after such order or request or
in default of the calling of such meeting within 60 days after such order or
request, such meeting may be called on similar notice by any stockholder or
stockholders owning in the aggregate not less than ten percent (10%) of the
total number of shares of Preferred Stock outstanding.  Notwithstanding the
provisions of this paragraph (C)(iii), no such special meeting shall be called
during the period within 60 days immediately preceding the date fixed for the
next annual meeting of the stockholders.

                 (iv)     In any default period, the holders of Common Stock,
and other classes of stock of the Corporation if applicable, shall continue to
be entitled to elect the whole number of Directors until the holders of
Preferred Stock shall have exercised their right to elect two (2) Directors
voting as a class, after the exercise of which right (x) the Directors so
elected by the holders of Preferred Stock shall continue in office until their
successors shall have been elected by such holders or until the expiration of
the default period, and (y) any vacancy in the Board of Directors may (except
as provided in paragraph (C)(ii) of this Section 3) be filled by vote of a
majority of the remaining Directors theretofore elected by the holders of the
class of stock which elected the Director whose office shall have become
vacant.  References in this paragraph (C) to Directors elected by the holders
of a particular class of stock shall





                                      A-3
<PAGE>   20
include Directors elected by such Directors to fill vacancies as provided in
clause (y) of the foregoing sentence.

         (v)     Immediately upon the expiration of a default period, (x) the
right of the holders of Series A Junior Participating Preferred Stock as a
class to elect Directors shall cease, (y) the term of any Directors elected by
the holders of Series A Junior Participating Preferred Stock as a class shall
terminate, and (z) the number of Directors shall be such number as may be
provided for in the Certificate of Incorporation or By-laws irrespective of any
increase made pursuant to the provisions of paragraph (C)(ii) of this Section 3
(such number being subject, however to change thereafter in any manner provided
by law or in the Certificate of Incorporation or By-laws).  Any vacancies in
the Board of Directors effected by the provisions of clauses (y) and (z) in the
preceding sentence may be filled by a majority of the remaining Directors.

         (D)     Except as set forth herein, holders of Series A Junior
Participating Preferred Stock shall have no special voting rights and their
consent shall not be required (except to the extent they are entitled to vote
with holders of Common Stock as set forth herein) for taking any corporate
action.

         Section 4.       Certain Restrictions.

         (A)     Whenever quarterly dividends or other dividends or
distributions payable on the Series A Junior Participating Preferred Stock as
provided in Section 2 are in arrears, thereafter and until all accrued and
unpaid dividends and distributions, whether or not declared, on shares of
Series A Junior Participating Preferred Stock outstanding shall have been paid
in full, the Corporation shall not

                 (i)      declare or pay dividends on, make any other
         distributions on, or redeem or purchase or otherwise acquire for
         consideration any shares of stock ranking junior (either as to
         dividends or upon liquidation, dissolution or winding up) to the
         Series A Junior Participating Preferred Stock;

                 (ii)     declare or pay dividends on or make any other
         distributions on any shares of stock ranking on a parity (either as to
         dividends or upon liquidation, dissolution or winding up) with the
         Series A Junior Participating Preferred Stock except dividends paid
         ratably on the Series A Junior Participating Preferred Stock and all
         such parity stock on which dividends are payable or in arrears in
         proportion to the total amounts to which the holders of all such
         shares are then entitled;

                 (iii)    redeem or purchase or otherwise acquire for
         consideration shares of any stock ranking on a parity (either as to
         dividends or upon liquidation, dissolution or winding up) with the
         Series A Junior Participating Preferred Stock provided that the
         Corporation may at any time redeem, purchase or otherwise acquire
         shares of any such parity stock in exchange for shares of any stock of
         the Corporation ranking junior (either as to dividends or upon
         dissolution, liquidation or winding up) to the Series A Junior
         Participating Preferred Stock; or

                 (iv)     purchase or otherwise acquire for consideration any
         shares of Series A Junior Participating Preferred Stock or any shares
         of stock ranking on a parity with the Series A Junior Participating
         Preferred Stock except in





                                      A-4
<PAGE>   21
         accordance with a purchase offer made in writing or by publication (as
         determined by the Board of Directors) to all holders of such shares
         upon such terms as the Board of Directors, after consideration of the
         respective annual dividend rates and other relative rights and
         preferences of the respective series and classes, shall determine in
         good faith will result in fair and equitable treatment among the
         respective series or classes.

         (B)     The Corporation shall not permit any subsidiary of the
Corporation to purchase or otherwise acquire for consideration any shares of
stock of the Corporation unless the Corporation could, under paragraph (A) of
this Section 4, purchase or otherwise acquire such shares at such time and in
such manner.

         Section 5.       Reacquired Shares.       Any shares of Series A
Junior Participating Preferred Stock purchased or otherwise acquired by the
Corporation in any manner whatsoever shall be retired and cancelled promptly
after the acquisition thereof.  All such shares shall upon their cancellation
become authorized but unissued shares of Preferred Stock and may be reissued as
part of a new series of Preferred Stock to be created by resolution or
resolutions of the Board of Directors, subject to the conditions and
restrictions on issuance set forth herein.

         Section 6.       Liquidation, Dissolution or Winding Up.   (A)
Upon any liquidation (voluntary or otherwise), dissolution or winding up of the
Corporation, no distribution shall be made to the holders of shares of stock
ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series A Junior Participating Preferred Stock unless, prior
thereto, the holders of shares of Series A Junior Participating Preferred Stock
shall have received per share, the greater of 100 times the exercise price per
Right or 100 times the payment made per share of Common Stock, plus an amount
equal to accrued and unpaid dividends and distributions thereon, whether or not
declared, to the date of such payment (the "Series A Liquidation Preference").
Following the payment of the full amount of the Series A Liquidation
Preference, no additional distributions shall be made to the holders of shares
of Series A Junior Participating Preferred Stock unless, prior thereto, the
holders of shares of Common Stock shall have received an amount per share (the
"Common Adjustment") equal to the quotient obtained by dividing (i) the Series
A Liquidation Preference by (ii) 100 (as appropriately adjusted as set forth in
subparagraph C below to reflect such events as stock splits, stock dividends
and recapitalizations with respect to the Common Stock) (such number in clause
(ii), the "Adjustment Number").  Following the payment of the full amount of
the Series A Liquidation Preference and the Common Adjustment in respect of all
outstanding shares of Series A Junior Participating Preferred Stock and Common
Stock, respectively, holders of Series A Junior Participating Preferred Stock
and holders of shares of Common Stock shall receive their ratable and
proportionate share of the remaining assets to be distributed in the ratio of
the Adjustment Number to 1 with respect to such Preferred Stock and Common
Stock, on a par share basis, respectively.

         (B)     In the event there are not sufficient assets available to
permit payment in full of the Series A Liquidation Preference and the
liquidation preferences of all other series of Preferred Stock, if any, which
rank on a parity with the Series A Junior Participating Preferred Stock then
such remaining assets shall be distributed ratably to the holders of such
parity shares in proportion to their respective liquidation preferences.  In
the event there are not sufficient assets available to permit payment in full
of the Common Adjustment, then such remaining assets shall be distributed
ratably to the holders of Common Stock.





                                      A-5
<PAGE>   22
         (C)     In the event the Corporation shall at any time after the
Rights Declaration Date (i) declare any dividend on Common Stock payable in
shares of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii)
combine the outstanding Common Stock into a smaller number of shares, then in
each such case the Adjustment Number in effect immediately prior to such event
shall be adjusted by multiplying such Adjustment Number by a fraction the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

         Section 7.       Consolidation, Merger, etc.       In case the
Corporation shall enter into any consolidation, merger, combination or other
transaction in which the shares of Common Stock are exchanged for or changed
into other stock or securities, cash and/or any other property, then in any
such case the shares of Series A Junior Participating Preferred Stock shall at
the same time be similarly exchanged or changed in an amount per share (subject
to the provision for adjustment hereinafter set forth) equal to 100 times the
aggregate amount of stock, securities, cash and/or any other property (payable
in kind), as the case may be, into which or for which each share of Common
Stock is changed or exchanged.  In the event the Corporation shall at any time
after the Rights Declaration Date (i) declare any dividend on Common Stock
payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock,
or (iii) combine the outstanding Common Stock into a smaller number of shares,
then in each such case the amount set forth in the preceding sentence with
respect to the exchange or change of shares of Series A Junior Participating
Preferred Stock shall be adjusted by multiplying such amount by a fraction the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that are outstanding immediately prior to such event.

         Section 8.       Redemption.      The shares of Series A Junior
Participating Preferred Stock shall not be redeemable.

         Section 9.       Ranking.         The Series A Junior Participating
Preferred Stock shall rank junior to all other series of the Corporation's

membership if he meets the eligibility requirements. All his Service with any
Affiliated Employer that would have been counted had he not been previously
excluded shall now be counted as Active Service for eligibility and vesting
purposes.

            2.9 SERVICE CREDIT REQUIRED UNDER FEDERAL LAW. An Employee shall be

method of calculating service is more beneficial for the Employee than the
method otherwise set out in this Article II.

            2.11 CREDIT FOR SERVICE WITH PIPER IMPACT, INC. A TENNESSEE

            3.1 ELIGIBILITY REQUIREMENTS. Effective April 1, 1997, each Employee
shall be eligible to participate in this Plan beginning on the entry date which
occurs with or next follows the date on which the Employee completes three
months of Active Service and attains the age of 21. However, all Employees who
are included in a unit of Employees covered by a collective bargaining agreement
between the Employees' representative and the Employer shall be excluded, even
if they have met the requirements for eligibility, if there has been good faith
bargaining between the Employer and the Employees' representative pertaining to
retirement benefits and the agreement does not require the Employer to include
such Employees in this Plan. In addition, a Leased Employee shall not be
eligible to participate in the Plan unless the Plan's qualified status is
dependent upon coverage of the Leased Employee. The Plan's entry dates will be
January 1, April 1, July 1 and October 1 of each Plan Year.

            3.2 ELIGIBILITY UPON REEMPLOYMENT. If an Employee Severs Service
with the Employer for any reason after fulfilling the eligibility requirements
but prior to the date he initially begins participating in the Plan, the
Employee shall be eligible to begin participation in this Plan on the day he
first completes an Hour of Service upon his return to employment with an
Employer. Once an Employee has become eligible to be a Member, his eligibility
shall continue until he Severs Service. A former Member shall be eligible to
recommence participation in this Plan on the first day he completes an Hour of
Service upon his return to employment with an Employer.

            3.3 FROZEN PARTICIPATION. An Employee employed by an Affiliated
Employer, which has not adopted this Plan, cannot actively participate in this
Plan even though he accrues Active Service. Likewise, if an Employee: (a) is
transferred from an Employer to an Affiliated Employer which has not adopted
this Plan, or (b) is a Member of this Plan when he is excluded under the
provisions of a collective bargaining agreement his participation becomes
inactive. Under these circumstances, the Member's Account becomes frozen and he
cannot contribute to the Plan nor can he share in the allocation of any Employer
Contribution or forfeitures for the period after he is transferred. However, his
Accounts shall continue to share in any appreciation or depreciation of the
Trust Fund and in any income earned or losses incurred by the Trust Fund during
the period of time that he is employed by an Affiliated Employer which has not
adopted this Plan, or is excluded from covered employment under the provisions
of a collective bargaining agreement.

to the Administrative Committee to prospectively receive Considered Compensation
from the Employer in a reduced amount and to have the Employer contribute an
amount equal to the amount of the reduction to the Trust Fund on account of the
Member. Any such salary deferral agreement shall be revocable in accordance with
its terms, provided that no revocation shall be retroactive or permit payment to
the Member of the amount required to be contributed to the Trust Fund. A Member
shall be entitled to prospectively modify his salary deferral agreement at least
once a year. A Member's right to benefits derived from Salary Deferral
Contributions made to the Plan on his behalf shall be nonforfeitable. The
election to have Salary Deferral Contributions made, the ability to change the
rate of Salary Deferral Contributions, the right to suspend Salary Deferral
Contributions, and the manner of commencing new Salary Deferral Contributions
shall be permitted under any uniform method determined by the Administrative
Committee from time to time.

            4.2 EMPLOYER MATCHING CONTRIBUTIONS. The Employer shall make an
Employer Matching Contribution in an amount equal to 25 percent of the Matched
Salary Deferral Contributions for all Members.

            4.3 ROLLOVER CONTRIBUTIONS AND PLAN-TO-PLAN TRANSFERS. The
Administrative Committee may permit Rollover Contributions by Members and/or
direct transfers to or from another qualified plan on behalf of Members from
time to time. If Rollover Contributions and/or direct transfers to or from
another qualified plan are permitted, the opportunity to make those
contributions and/or direct transfers must be made available to Members on a
nondiscriminatory basis. For this purpose only, all Employees in the Eligible
Class shall be considered to be Members of the Plan even though they may not
have met the eligibility requirements. However, they shall not be entitled to
elect to have Salary Deferral Contributions made or to share in Employer
Contributions or forfeitures unless and until they have met the requirements for
eligibility, contributions and allocations. A Rollover Contribution shall not be
accepted unless it is directly rolled over to this Plan in a rollover described
in Section 401(a)(31) of the Code. A Member shall not be permitted to make a
Rollover Contribution if the property he intends to contribute is for any reason
unacceptable to the Trustee. A Rollover Contribution Account shall be
established for any Employee who makes a Rollover Contribution.

            A direct transfer of assets from another qualified plan in a
transfer subject to the requirements of Section 414(l) of the Code shall not be
accepted if it was at any time part of (a) a defined benefit plan (as defined in
Section 401(a) or 414(j) of the Code), (b) a defined contribution plan (as
defined in Sections 401(a) and 414(i) of the


                                      IV-1
<PAGE>   20
Code) which is subject to the minimum funding standards of Section 412 of the
Code, (c) any other qualified plan which has joint and survivor annuity benefits
or qualified preretirement survivor annuity benefits as described in Section 417
of the Code, or (d) a plan which permits a distribution or withdrawal in a form
not permitted under this Plan.

            4.4 QUALIFIED NONELECTIVE EMPLOYER CONTRIBUTIONS. The Employer may
make a Qualified Nonelective Employer Contribution in such amount, if any, as
shall be determined by the Employer. A Member's right to benefits derived from
Qualified Nonelective Employer Contributions made to the Plan on his behalf
shall be nonforfeitable. In no event will Qualified Nonelective Employer
Contributions be distributed before Salary Deferral Contributions may be
distributed

            4.5 RESTORATION CONTRIBUTIONS. The Employer shall, for each Plan
Year, make a restoration contribution in an amount equal to the sum of (a) such
amount, if any, as shall be necessary to fully restore all Matching Employer
Contribution Accounts required to be restored pursuant to the provisions of
Section 5.9, after application of all forfeitures and any appreciation in the
value of the Trust Fund available for such restoration; plus (b) an amount equal
in value to the value of forfeited benefits described in and payable under
Section 7.9.

            4.6 $7,000 LIMIT ON SALARY DEFERRAL CONTRIBUTIONS. The maximum
Salary Deferral Contribution that a Member may elect to have made on his behalf
during the Member's taxable year may not, when added to the amounts deferred
under other plans or arrangements described in Code Sections 401(k), 408(k) and
403(b) exceed $7,000 (as adjusted by the Secretary of Treasury). If this dollar
limitation is exceeded during any taxable year of the Member, the excess of the
amounts deferred on behalf of the Member under plans or arrangements described
in Code Sections 401(k), 408(k) and 403(b) during the Member's taxable year over
the dollar limitation (the "Excess Deferral") as adjusted by any earnings or
losses thereon will be distributed to the Member no later than April 15
following the Member's taxable year in which the Excess Deferral was made.

            The income allocable to Excess Deferrals for the taxable year of the
Member shall be determined by multiplying the income for the taxable year of the
Member allocable to Salary Deferral Contributions by a fraction. The numerator
of the fraction is the amount of Excess Deferrals made on behalf of the Member
for the taxable year. The denominator of the fraction is the Member's total
Salary Deferral Account balance as of the beginning of the taxable year plus the
Member's Salary Deferral Contributions for the Plan Year.

            For purposes of applying the requirements of Code Sections 4.7 and
VIII, Excess Deferrals will not be disregarded merely because they are Excess
Deferrals or because they are distributed in accordance with this Section.
However, Excess Deferrals made to the Plan on behalf of Non-Highly Compensated
Employees are not to be taken into account under Section 4.7.


                                      IV-2
<PAGE>   21
            4.7 ACTUAL DEFERRAL PERCENTAGE FOR HIGHLY COMPENSATED EMPLOYEES. The
Actual Deferral Percentage for Highly Compensated Employees for any Plan Year
must bear a relationship to the Actual Deferral Percentage for all other
eligible Employees for the Plan Year which meets either of the following tests:

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

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

For purposes of this test an eligible Employee is an Employee who is eligible to
make Salary Deferral Contributions for all or part of a Plan Year. A person who
is suspended from making Salary Deferral Contributions because he has made a
withdrawal is an eligible Employee. If no Salary Deferral Contributions are made
for an eligible Employee the deferral ratio that will be included for him in
determining the Actual Deferral Percentage is zero. If this Plan and any other
plan or plans which include cash or deferred arrangements are considered as one
plan for purposes of Section 401(a)(4) or 410(b) of the Code, the cash or
deferred arrangements included in this Plan and the other plans shall be treated
as one plan for these tests. If any Highly Compensated Employee is a Member of
this Plan and any other cash or deferred arrangements of the Employer, when
determining the deferral percentage of the Employee, all of the cash or deferred
arrangements are treated as one.

            As soon as practicable after the close of each Plan Year, the
Committee shall determine whether the Actual Deferral Percentage for the Highly
Compensated Employees would exceed the limitation. If the limitation would be
exceeded for a Plan Year, before the close of the following Plan Year (a) the
amount of Excess 401(k) Contributions for that Plan Year (and any income
allocable to those Contributions as calculated in the specific manner required
by Section 4.10) shall be distributed, or (b) the Employer may make a Qualified
Nonelective Employer Contribution which is treated as a Section 401(k)
Contribution and allocated only to those Members who are Non-Highly Compensated
Employees. Qualified Nonelective Employer Contributions will be treated as
Section 401(k) Contributions only if the conditions described in Regulation
Section 1.401(k)-1(b)(5) are satisfied. Qualified Nonelective Employer
Contributions will be treated as Section 401(k) Contributions for a Plan Year
only if they are allocated to Members' Accounts as of a date within that Plan
Year and are actually paid to the Trust no later than the end of the 12-month
period immediately following the Plan Year to which the contributions relate.
Any distributions of the Excess 401(k) Contributions for any Plan Year are to be
made to Highly Compensated Employees on the basis of the respective portions of
the Excess 401(k) Contributions attributable to each of them. The amount of
Excess 401(k) Contributions to be distributed for any Plan Year must be reduced
by any excess Salary Deferral Contributions previously distributed for the
taxable year ending in the same Plan Year.


                                      IV-3
<PAGE>   22
            A Salary Deferral Contribution will be taken into account under the
actual deferral percentage test of Code Section 401(k) and this Section for a
Plan Year only if it relates to Annual Compensation that either would have been
received by the Employee in the Plan Year (but for the deferral election) or is
attributable to services performed by the employee in the Plan Year and would
have been received by the Employee within 2 1/2 months after the close of the
Plan Year (but for the deferral election). In addition, a Section 401(k)
Contribution will be taken into account under the actual deferral percentage
test of Code Section 401(k) and this Section for a Plan Year only if it is
allocated to an Employee as of a date within that Plan Year. For this purpose a
Section 401(k) Contribution is considered allocated as of a date within a Plan
Year if the allocation is not contingent on participation or performance of
services after such date and the Section 401(k) Contribution is actually paid to
the Trust no later than 12 months after the Plan Year to which the Section 40(k)
Contribution relates.

            Failure to correct Excess 401(k) Contributions by the close of the
Plan Year following the Plan Year for which they were made will cause the Plan
to fail to be a qualified cash or deferred arrangement for the Plan Year for
which the Excess Contributions were made and for all subsequent years they
remain in the Trust. Also, the Employer will be liable for a 10% excise tax on
the amount of Excess Contributions unless they are corrected within 2 1/2 months
after the close of the Plan Year for which they were made.

            4.8 CONTRIBUTION PERCENTAGE TEST. The Contribution Percentage for
eligible Highly Compensated Employees for any Plan Year must not exceed the
greater of the following:

            (a) The Contribution Percentage for all other eligible Employees
      multiplied by 1.25; or

            (b) The lesser of the Contribution Percentage for all other eligible
      Employees multiplied by two, or the Contribution Percentage for all other
      eligible Employees plus two percentage points.

For purposes of this test an eligible Employee is an Employee who is directly or
indirectly eligible to receive an allocation of Matching Employer Contributions
for all or part of the Plan Year. Except as provided below, an Employee who
would be eligible to receive an allocation of Matching Employer Contributions
but for his election not to participate is an eligible Employee. An Employee who
would be eligible to receive an allocation of Matching Employer Contributions
but for the limitations on his Annual Additions imposed by Section 415 of the
Code is an eligible Employee.

            If no Section 401(m) Contributions are made on behalf of an eligible
Employee the Actual Contribution Ratio that shall be included for him in
determining the Contribution Percentage is zero. If this Plan and any other plan
or plans to which Section 401(m) Contributions are made are considered as one
plan for purposes of Section 401(a)(4) or 410(b) of the Code, this Plan and
those plans are to be treated as one. The Actual Contribution Ratio of a Highly
Compensated Employee who is eligible to participate in more than one plan of an
Affiliated employer to which employee or


                                      IV-4
<PAGE>   23
matching contributions are made is calculated by treating all the plans in which
the Employee is eligible to participate as one plan. However, plans that are not
permitted to be aggregated under Regulation Section 1.410(m)-1(b)(3)(ii) are not
aggregated for this purpose.

            A Matching Employer Contribution will be taken into account under
this Section for a Plan Year only if (1) it is allocated to the Employee's
Account as of a date within the Plan Year, (2) it is paid to the Trust no later
than the end of the 12 month period beginning after the close of the Plan Year,
and (3) it is made on behalf of an Employee on account of his Salary Deferral
Contributions for the Plan Year.

            At the election of the Employer, a Member's Salary Deferral
Contributions, and Qualified Nonelective Employer Contributions made on behalf
of the Member during the Plan Year shall be treated as Section 401(m)
Contributions that are Matching Employer Contributions provided that the
conditions set forth in Regulation Section 1.401(m)-1(b)(5) are satisfied.
Salary Deferral Contributions may not be treated as Employer Matching
Contributions for purposes of the contribution percentage test set forth in this
Section unless such contributions, including those taken into account for
purposes of the test set forth in this Section, satisfy the actual deferral
percentage test set forth in Section 4.7. Moreover, Salary Deferral
Contributions and Qualified Nonelective Employer Contributions may not be taken
into account for purposes of the test set forth in this Section to the extent
that such contributions are taken into account in determining whether any other
contributions satisfy the actual deferral percentage test set forth in Section
4.7. Finally, Salary Deferral Contributions and Qualified Nonelective Employer
Contributions may be taken into account for purposes of the test set forth in
this Section only if they are allocated to the employee's Account as of a date
within the Plan Year being tested within the meaning of Regulation Section
1.401(k)-1(b)(4).

            4.9 CONTRIBUTION PERCENTAGE FAIL SAFE PROVISION. If the limitation
set forth in Section 4.8 would be exceeded for any Plan Year, before the close
of the following Plan Year (a) the amount of the Excess Aggregate 401(m)
Contributions for that Plan Year (and any income allocable to those
Contributions as calculated in the manner set forth in Section 4.10) shall be
either distributed, or forfeited to the extent they are not vested, or (b) the
Employer may make a Qualified Nonelective Employer Contribution which it elects
to have treated as a Section 401(m) Contribution. Any distributions of the
Excess Aggregate 401(m) Contributions for any Plan Year are to be made to Highly
Compensated Employees on the basis of the respective portions of the amounts
attributable to each of them. Forfeitures of Excess Aggregate 401(m)
Contributions shall be allocated to Members who are Non-Highly Compensated
Employees as if such contributions were additional Employer Matching
Contributions for the Plan Year.

            4.10 INCOME ALLOCABLE TO EXCESS 401(k) CONTRIBUTIONS AND EXCESS
AGGREGATE 401(m) CONTRIBUTIONS. The income allocable to Excess 401(k)
Contributions for the Plan Year shall be determined by multiplying the income
for the Plan Year allocable to Section 401(k) Contributions by a fraction. The
numerator of the fraction shall be the amount of Excess 401(k) Contributions
made on behalf of the Member for


                                      IV-5
<PAGE>   24
the Plan Year. The denominator of the fraction shall be the Member's total
Account balance attributable to Section 401(k) Contributions as of the beginning
of the Plan Year plus the Member's Section 401(k) Contributions for the Plan
Year. The income allocable to Excess Aggregate 401(m) Contributions for a Plan
Year shall be determined by multiplying the income for the Plan Year allocable
to Section 401(m) Contributions by a fraction. The numerator of the fraction
shall be the amount of Excess Aggregate 401(m) Contributions made on behalf of
the Member for the Plan Year. The denominator of the fraction shall be the
Member's total Account balance attributable to Section 401(m) Contributions as
of the beginning of the Plan Year plus the Member's Section 401(m) Contributions
for the Plan Year.

            4.11 ADDITIONAL REQUIRED TEST IF ALTERNATIVE COMPLIANCE IS USED. If
the second alternative permitted in Sections 4.7 and 4.8 is used for both the
Actual Deferral Percentage test and the Contribution Percentage test the
following additional limitation on Salary Deferral Contributions shall apply.
The Actual Deferral Percentage plus the Contribution Percentage of the eligible
Highly Compensated Employees cannot exceed the greater of (a) or (b), where

            (a) is the sum of:

                  (i) 1.25 times the greater of the Actual Deferral Percentage
            or the Contribution Percentage of the eligible Non-Highly
            Compensated Employees, and

                  (ii) the lesser of (x) two percentage points plus the lesser
            of the Actual Deferral Percentage or the Contribution Percentage of
            the eligible Non-Highly Compensated Employees or (y) two times the
            lesser of the Actual Deferral Percentage or the Contribution
            Percentage of the group of eligible Non-Highly Compensated
            Employees; and

            (b) is the sum of:

                  (i) 1.25 times the lesser of the Actual Deferral Percentage or
            the Contribution Percentage of the eligible Non-Highly Compensated
            Employees, and

                  (ii) the lesser of (x) two percentage points plus the greater
            of the Actual Deferral Percentage or the Contribution Percentage of
            the eligible Non-Highly Compensated Employees or (y) two times the
            greater of the Actual Deferral Percentage or the Contribution
            Percentage of the group of eligible Non-Highly Compensated
            Employees.

            If the limitation would be exceeded for any Plan Year, before the
close of the following Plan Year the Actual Deferral Percentage or Contribution
Percentage of the eligible Highly Compensated Employees, or a combination of
both, shall be reduced by distributions made in the manner described in the
Regulations. These distributions


                                      IV-6
<PAGE>   25
shall be in addition to and not in lieu of distributions required for Excess
401(k) Contributions and Excess Aggregate 401(m) Contributions.

            4.12 NONDEDUCTIBLE CONTRIBUTIONS PROHIBITED. Notwithstanding any
other provision of the Plan, no Employer shall make any contribution that would
be a "nondeductible contribution" within the meaning of Section 4972 of the
Code.

            4.13 FORM OF PAYMENT OF CONTRIBUTIONS. Contributions may be paid to
the Trustee either in cash or in qualifying employer securities (as such term is
defined in Section 407(d) of ERISA) or any combination thereof, provided that
payment may not be made in any form constituting a prohibited transaction under
Section 4975 of the Code or Section 406 of ERISA.

            4.14 DEADLINE FOR PAYMENT OF EMPLOYER CONTRIBUTIONS. The Employer's
Salary Deferral Contribution and Employer Matching Contribution shall be paid to
the Trustee in installments. The installment for each payroll period shall be
paid within 60 days after the end of the calendar quarter in which such payroll
period ends, and shall be in an amount equal to the amount by which all Members'
Considered Compensation was reduced pursuant to salary deferral agreements (as
described in Section ) for such period, plus the amount of the Employer Matching
Contribution for such period. The Qualified Nonelective Employer Contributions
of the Employer for each Plan Year shall be paid to the Trustee in one or more
installments, as the Employer may from time to time determine; provided,
however, that the Qualified Nonelective Employer Contribution may be paid not
later than the time prescribed by law (including extensions thereof) for filing
the Employer's income tax return for its taxable year ending with or within such
Plan Year.

            4.15 RETURN OF CONTRIBUTIONS FOR MISTAKE, DISQUALIFICATION OR
DISALLOWANCE OF DEDUCTION. Subject to the limitations of Section 415 of the
Code, the assets of the Trust shall not revert to any Employer or be used for
any purpose other than the exclusive benefit of the Members and their
Beneficiaries and the reasonable expenses of administering the Plan except:

            (a) any Contribution made because of a mistake of fact may be repaid
      to the Employer within one year after the payment of the Contribution;

            (b) any Contribution conditioned upon the Plan's initial
      qualification under Section 401 of the Code or the initial qualification
      of an Employer's adoption of the Plan, if later, may be repaid to the
      Employer within one year after the date of denial of the initial
      qualification of the Plan or of its adoption by the Employer; and

            (c) any and all Employer Contributions are conditioned upon their
      deductibility under Section 404 of the Code; therefore, to the extent the
      deduction is disallowed, the Contributions may be repaid to the Employer
      within one year after the disallowance.


                                      IV-7
<PAGE>   26
            The Employer has the exclusive right to determine if a Contribution
or any part of it is to be repaid or is to remain as a part of the Trust Fund
except that the amount to be repaid is limited, if the Contribution is made by
mistake of fact or if the deduction for the Contribution is disallowed, to the
excess of the amount contributed over the amount that would have been
contributed had there been no mistake or over the amount disallowed. Earnings
which are attributable to any excess contribution cannot be repaid. Losses
attributable to an excess contribution must reduce the amount that may be
repaid. All repayments of mistaken Contributions or Contributions which are
disallowed are limited so that the balance in a Member's Account cannot be
reduced to less than the balance that would have been in the Member's Account
had the mistaken amount or the amount disallowed never been contributed.

                      ALLOCATION AND VALUATION OF ACCOUNTS


            5.1 INFORMATION STATEMENTS FROM EMPLOYER. As soon as practical after
the last day of each calendar quarter, the Employer shall provide the
Administrative Committee with a schedule setting forth the amount of its Salary
Deferral Contribution, Employer Matching Contribution, Qualified Nonelective
Employer Contribution, and restoration contribution; the names of its Members,
the number of Years of Vesting Service of each of its Members, the amount of
Considered Compensation paid to each Member, and the amount of Considered
Compensation paid to all its Members. Such schedules shall be conclusive
evidence of such facts.

            5.2 ALLOCATION OF SALARY DEFERRAL CONTRIBUTION. The Administrative
Committee shall allocate the Employer's Salary Deferral Contribution among the
Employer's Members by allocating to each such Member the amount by which his
Considered Compensation was reduced pursuant to a salary deferral agreement (as
described in Section 4.1 and shall credit each such Member's share to the
Member's Salary Deferral Contribution Account.

            5.3 ALLOCATION OF MATCHING EMPLOYER CONTRIBUTION. The Administrative
Committee shall separately allocate the Employer Matching Contribution among the
Employer's Members in the proportion which the Matched Salary Deferral
Contributions of each such Member bears to the total Matched Salary Deferral
Contributions of all such Members. Each Member's proportionate share shall be
credited to his Matching Employer Contribution Account.

            5.4 ALLOCATION OF QUALIFIED NONELECTIVE EMPLOYER CONTRIBUTION. The
Administrative Committee shall separately allocate the Qualified Nonelective
Employer Contribution among the Non-Highly Compensated Employees who are Members
based upon each such Member's Considered Compensation as compared to the
Considered Compensation of all such Members.

            5.5 ALLOCATION OF DIVIDENDS ON SPONSOR STOCK. Cash and Sponsor Stock
dividends paid with respect to Sponsor Stock shall be allocated among the
Members and former Members with Account balances in proportion to the number of
shares of Sponsor Stock (of the class with respect to which the dividend is
paid) allocated to Member's or former Member's Account as of the record date for
the dividend.

            5.6 SPONSOR STOCK SPLITS. If the shares of Company Stock are
subdivided, the additional shares acquired by the Trustee upon the subdivision
will be allocated among the Members and former Members with Account balances in
proportion to the number of shares of Sponsor Stock (of the class with respect
to which the subdivision is made) allocated to the Member's or former Member's
Account as of the record date for the subdivision.


                                       V-1
<PAGE>   28
           5.7 VALUATION OF ACCOUNTS. A Member's or former Member's Accounts
shall be valued at fair market value on each Valuation Date. The earnings and
losses attributable to any asset in the Trust Fund will be allocated solely to
the Account of the Member or former Member on whose behalf the investment in the
asset was made. In determining the fair market value of the Members' or former
Member's Accounts, the Trustee shall utilize such sources of information as it
may deem reliable including, but not limited to, stock market quotations,
statistical evaluation services, newspapers of general circulation, financial
publications, advice from investment counselors or brokerage firms, or any
combination of sources which in the opinion of the Trustee will provide the
price such assets were last traded at on a registered stock exchange; provided,
however, that with respect to regulated investment company shares, the Trustee
shall rely exclusively on information provided to it by the investment adviser
to such funds.

            5.8 ALLOCATION OF FORFEITURES. At the time a forfeiture occurs, the
amount forfeited will first be used to reinstate any Account required to be
reinstated under Section 5.9, and any remaining amount will be applied to the
payment of Matching Employer Contributions.

            5.9 RESTORATION OF FORFEITED AMOUNTS. If a Member or former Member
who forfeited any portion of his Matching Employer Contribution Account pursuant
to the provisions of Section 7.10 resumes employment covered under the Plan,
then the following provisions shall apply:

            (a) REPAYMENT REQUIREMENT. The Member's Employer Matching
      Contribution Account shall be restored if he repays to the Trustee the
      full amount of any distribution from the Employer Matching Contribution
      Account with respect to which the forfeiture arose. Such repayment must be
      made prior to the earlier of (a) the date on which he incurs a Period of
      Severance of five years, or (b) the fifth anniversary of the first date on
      which the Member is subsequently re-employed by the Employer.

            (b) MEMBERS WITH NO VESTED INTEREST. If a Member or former Member
      who forfeited any portion of his Employer Matching Contribution Account
      pursuant to the provisions of Section 7.10 received no distribution from
      his Employer Matching Contribution Account as a result of his termination
      of participation in the Plan (because his vested percentage was zero),
      that Account will be restored if, and only if, he resumes employment
      covered under the Plan prior to incurring a Period of Severance of five
      years.

            (c) AMOUNT RESTORED. The amount to be restored under the preceding
      provisions of this Section shall be the dollar value of the amount in the
      Member's Employer Matching Contribution Account, both the amount
      distributed and the amount forfeited, unadjusted by any subsequent gains
      or losses. The Member's Employer Matching Contribution Account balance
      shall be restored as soon as administratively


                                       V-2
<PAGE>   29
      practicable after the later of the date the Member resumes employment
      covered under the Plan or the date on which any required repayment is
      completed. No distribution shall be made to a Member from his Employer
      Matching Contribution Account as a result of a prior Separation from
      service after the restoration of such Account has been effectuated.

            (d) NO OTHER BASIS FOR RESTORATION. Except as otherwise provided
      above, a Member's Employer Matching Contribution Account shall not be
      restored upon resumption of employment covered by the Plan. Any portion of
      the Trust Fund attributable to Years of Service prior to resumption of
      employment by a Member whose Employer Matching Contribution Account has
      not been restored shall be held and distributed in accordance with
      applicable provisions of the Plan and elections made thereunder. A
      separate Employer Matching Contribution Account shall be established and
      maintained for Employer Matching Contributions allocable to such a Member
      after his resumption of employment covered by the Plan.

            5.10 NO VESTING UNLESS OTHERWISE PRESCRIBED. No allocations,
adjustments, credits, or transfers shall ever vest in any Member or former
Member any right, title, or interest in the Trust Fund except at the times and
upon the terms and conditions herein set forth.

                           LIMITATIONS ON ALLOCATIONS


            The Annual Additions that may be credited to a Member's Accounts
under this Plan and any other qualified defined contribution plan maintained by
an Affiliated Employer for any Limitation Year will not exceed the lesser of
$30,000 (as adjusted by the Secretary of Treasury) or 25 percent of the Member's
Annual Compensation for the Limitation Year. The Plan will be operated in
compliance with section 415 of the Code and the Regulations thereunder, the
terms of which are incorporated herein by reference.

            If Annual Additions are made in excess of the limitation set forth
in this Section, to the maximum extent permitted by law, all such excess Annual
Additions shall be attributed to this Plan.

            If an excess Annual Addition attributed to this Plan is held or
contributed as a result of the allocation of forfeitures, a reasonable error in
estimating a Member's Annual Compensation, a reasonable error in calculating the
maximum Salary Deferral Contribution that may be made for a Member under section
415 of the Code or because of any other facts and circumstances that the
Commissioner of Internal Revenue finds to be justified, the excess Annual
Addition shall be corrected as follows:

            (a) First, the excess Annual Addition shall be reduced to the extent
      necessary by distributing to the Employee Salary Deferral Contributions
      and earnings thereon. These distributed amounts are disregarded for
      purposes of Sections 4.6 and 4.7 of the Plan.

            (b) If the Member is still employed by the Employer at the end of
      the Plan Year, any remaining excess funds shall be placed in an
      unallocated suspense account to be applied to reduce future Employer
      Contributions for that Member for as many Plan Years as are necessary to
      exhaust the suspense account in keeping with the amounts which would
      otherwise be allocated to that Member's Account.

            (c) If the Member is not employed by the Employer at the end of the
      Plan Year, the remaining excess funds shall be placed in an unallocated
      suspense account to reduce future Employer Contributions for all remaining
      Members for as many Plan Years as are necessary to exhaust the suspense
      account.

            (d) If the Plan terminates prior to the exhaustion of the suspense
      account, the remaining amount shall revert to the Employer.

                                    BENEFITS


            7.1 VALUATION OF ACCOUNTS FOR WITHDRAWALS AND DISTRIBUTIONS. For the
purpose of making a distribution or withdrawal, a Member's Accounts shall be his
Accounts as valued as of the Valuation Date which is coincident with or next
follows the event which caused the distribution or withdrawal, adjusted for
Contributions, distributions and withdrawals, if any, made between the Valuation
Date and that event. The amount of a Plan benefit payable for any reason will be
reduced by the unpaid balance of a loan to a Member or Beneficiary.

            7.2 DEATH BENEFIT. If a Member or retired Member dies, the death
benefit payable to the Member's spouse or designated Beneficiary or
Beneficiaries shall be 100% of the remaining amount in all of his Accounts as of
the day he dies.

            7.3 RETIREMENT BENEFIT. A Member may retire on the first day of any
month after he attains his Retirement Age. If a Member retires, he is entitled
to receive 100% of all of his Accounts as of the day he retires.

            7.4 DISABILITY BENEFIT. If a Member's employment with an Employer is
terminated and the Committee determines he is suffering from a Disability, he is
entitled to receive 100% of all of his Accounts as of the day he terminated
because of his Disability.

            7.5 SEVERANCE BENEFIT. If a Member severs employment with the
Employer and all Affiliated Employers for any reason other than death,
retirement or disability, he is entitled to receive (a) 100% of all of his
Accounts, except his Matching Employer Contribution Account, and (b) that
percentage of his Matching Employer Contribution Account, if any, as shown in
the vesting schedule below, as of the day he severs employment.

            Prior to a Member's termination of employment with the Employer and
all Affiliated Employers, he will have a nonforfeitable interest in the portion
of the Matching Employer Contributions specified in the above vesting schedule.

            7.6 DISTRIBUTIONS TO DIVORCED SPOUSE. If the Committee determines
that a judgment, decree or order relating to child support, alimony payments or
marital property rights of the spouse, former spouse, child or other dependent
of the Member is a qualified domestic relations order which complies with a
state's domestic relations law or community property law and Section 414(p) of
the Code or is a domestic relations order entered before January 1, 1985, the
Committee may direct the Trustee to distribute the awarded property to the
person named in the award but only in the manner permitted under this Plan. To
be a qualified domestic relations order, the order must clearly specify: (a) the
name and last known mailing address of the Member and each alternate payee under
the order, (b) the amount or percentage of the Member's benefits to be paid from
the Plan to each alternate payee or the manner in which the amount or percentage
can be determined, (c) the number of payments or periods for which the order
applies, (d) the plan to which the order applies, and (e) all other requirements
set forth in Section 414(p) of the Code. If a distribution is made at a time
when the Member is not fully vested, a separate subaccount shall be created for
the remaining portion of each Account which was not fully vested. That
subaccount shall then remain frozen: that is, no further contributions of any
form and no forfeitures shall be allocated to the subaccount; however, it shall
receive its proportionate share of trust appreciation or depreciation and income
earned on or losses incurred by the Trust Fund. To determine the Member's vested
interest in each subaccount at any future time, the Committee shall add back to
the subaccount at that time the amount that was previously distributed under the
qualified domestic relations order, shall multiply the reconstituted subaccount
by the vesting percentage, and shall then subtract the amount that was
previously distributed. The remaining amount is the Member's vested interest in
the subaccount at that time.

            7.7 WITHDRAWALS. Only the following withdrawals may be made during
employment:

            (a) A Member is entitled to receive a withdrawal from his Salary
      Deferral Contribution Account, his vested interest in his Matching
      Employer Contribution Account and his Rollover Account in the event of an
      immediate and heavy financial need incurred by the Member and the
      Committee's determination that the withdrawal is necessary to alleviate
      that hardship.

            A distribution shall be made on account of financial hardship only
      if the distribution is for: (i) Expenses for medical care described in
      Section 213(d) of the Code previously incurred by the Member, the Member's
      spouse, or any dependents of the Member (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, (ii) costs directly related to the purchase
      (excluding mortgage payments) of a principal residence for the Member,
      (iii) payment of tuition and related educational fees for the next 12
      months of post-secondary education for the Member, his or her spouse,
      children, or dependents (as defined in Section 152 of the Code), (iv)
      payments necessary to prevent the eviction of the Member from his
      principal residence or foreclosure on the mortgage of the Member's


                                      VII-2
<PAGE>   33
      principal residence, or (v) any other event added to this list by the 
      Commissioner of Internal Revenue.

            A distribution to satisfy an immediate and heavy financial need
      shall not be made in excess of the amount of the immediate and heavy
      financial need of the Member and the Member must have 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. The amount of a Member's immediate and heavy financial
      need includes any amounts necessary to pay any federal, state or local
      income taxes or penalties reasonably anticipated to result from the
      financial hardship distribution.

            The Member's hardship distribution shall terminate his right to have
      the Employer make any Salary Deferral Contributions on his or her behalf
      until the next time Salary Deferral Contributions are permitted after the
      lapse of 12 months following the hardship distribution and his or her
      timely filing of a written request to resume his Salary Deferral
      Contributions. When the Member resumes Salary Deferral Contributions, he
      cannot have the Employer make any Salary Deferral Contributions in excess
      of the limit in Section 402(g) of the Code for that taxable year reduced
      by the amount of Salary Deferral Contributions made by the Employer on the
      Member's behalf during the taxable year of the Member in which he received
      the hardship distribution. In addition, for 12 months after he receives a
      hardship distribution from this Plan the Member is prohibited from making
      elective contributions and employee contributions to all other qualified
      and nonqualified plans of deferred compensation maintained by the
      Employer, including stock option plans, stock purchase plans and Code
      Section 401(k) cash or deferred arrangements that are part of cafeteria
      plans described in Section 125 of the Code. However, the Member is not
      prohibited from making mandatory employee contributions to a defined
      benefit plan, or contributions to a health or welfare benefit plan,
      including one that is part of a cafeteria plan within the meaning of
      Section 125 of the Code.

            Financial hardship withdrawals will be made in the following order:
      First withdrawals will be made from the Member's Rollover Account, then
      from his Matching Employer Contribution Account, and finally, from his or
      her Salary Deferral Contribution Account. A Member shall not be entitled
      to make a financial hardship withdrawal of any amount credited to his
      Qualified Nonelective Employer Contribution Account, or of any income that
      is allocable or credited to his Member's Salary Deferral Contribution
      Account.

            (b) A Member may withdraw part or all of his vested Account balance
      on or after the date that he attains age 59-1/2.

            7.8 LOANS. The Committee may direct the Trustees to make loans to
Members (and Beneficiaries who are "parties in interest" within the meaning of
ERISA) who have a vested interest in the Plan. The Loan Committee established by
the Committee will be responsible for administering the Plan loan program. All
loans will comply with the following requirements:

            (a) All loans will be made solely from the Member's or Beneficiary's
      Account.

            (b) Loans will be available on a nondiscriminatory basis to all
      Beneficiaries who are "parties in interest" within the meaning of ERISA,
      and to all Members.

            (c) Loans will not be made for less than $1,000.

            (d) The maximum amount of a loan may not exceed the lesser of (A)
      $50,000 reduced by the person's highest outstanding loan balance from the
      Plan during the preceding one year period, or (B) one-half of the present
      value of the person's vested Account balance under the Plan determined as
      of the date on which the loan is approved by the Loan Committee.

            (e) Any loan from the Plan will be evidenced by a note or notes
      (signed by the person applying for the loan) having such maturity, bearing
      such rate of interest, and containing such other terms as the Loan
      Committee will require by uniform and nondiscriminatory rules consistent
      with this Section and proper lending practices.

            (f) All loans will bear a reasonable rate of interest which will be
      established by the Loan Committee. In determining the proper rate of
      interest to be charged, at the time any loan is made or renewed, the Loan
      Committee will contact at least two of the largest banks in the geographic
      location in which the Member or Beneficiary resides to determine what
      interest rate the banks would charge for a similar loan taking into
      account the collateral offered.

            (g) Each loan will be fully secured by a pledge of the borrowing
      person's vested Account balance. No more than fifty percent (50%) of the
      person's vested Account balance (determined immediately after the
      origination of the loan) will be considered as security for any loan.

            (h) The term of the loan will not be less than 18 months. Generally,
      the term of the loan will not be more than 5 years. The Loan Committee may
      agree to a longer term (but not more than 7 years) only if such term is
      otherwise reasonable and the proceeds of the loan are to be used to
      acquire a dwelling which will be used within a reasonable time (determined
      at the time the loan is made) as the principal residence of the borrowing
      person.


                                      VII-4
<PAGE>   35
            (i) The loan agreement will require level amortization over the term
      of the loan. A Member's loan agreement will also require that loan
      repayments be made through payroll deductions.

            (j) If a person fails to make a required payment within 30 days of
      the due date set forth in the loan agreement, the loan will be in default.

            (k) If a Member has an outstanding loan from the Plan at the time he
      terminates employment with the Employer and all Affiliated Employers, the
      outstanding loan principal balance and any accrued but unpaid interest
      will become immediately due in full. The Member will have the right to
      immediately pay the Trustee that amount. If the Member fails to repay the
      loan, the Trustee will foreclose on the loan and the Member will be deemed
      to have received a Plan distribution of the amount foreclosed upon. The
      Trustee will not foreclose upon a Member's Salary Deferral Contributions
      Account or Qualified Nonelective Employer Contributions Account until the
      Member has terminated employment with the Employer and all Affiliated
      Employers.

            (l) If a Beneficiary defaults on his loan, the Trustee will
      foreclose on the loan and the Beneficiary will be deemed to have received
      a Plan distribution of the amount foreclosed upon.

            (m) No person shall be entitled to apply for a new Plan loan until
      at least 90 days have transpired since he fully repaid his last loan from
      the Plan.

            (n) No amount that is pledged as collateral for a Plan loan to a
      Participant will be available for withdrawal before he has fully repaid
      his loan.

            (o) All interest payments made pursuant to the terms of the loan
      agreement will be credited to the borrowing person's Account and will not
      be considered as general earnings of the Trust Fund to be allocated to
      other Members.

            7.9 FORFEITURE BY LOST MEMBERS OR BENEFICIARIES. If a person who is
entitled to a distribution cannot be located during a search period of 60 days
after the Trustee has initially attempted making payment, that person's Account
shall be forfeited. However, if at any time prior to the termination of this
Plan and the complete distribution of the Trust Fund, the former Member or
Beneficiary files a claim with the Committee for the forfeited benefit, that
benefit shall be reinstated (without adjustment for trust income or losses
during the forfeited period) effective as of the date of the receipt of the
claim. As soon as appropriate following the Employer's Contribution of the
reinstated amount, it shall be paid to the former Member or Beneficiary in a
single sum.


                                      VII-5
<PAGE>   36
            7.10 FORFEITURE ON TERMINATION OF PARTICIPATION. If as a result of
terminating his participation in the Plan a former Member receives a
distribution of his entire vested interest in his Account, the nonvested amount
in his Account is immediately forfeited. A former Member who received no
distribution upon his termination of employment with all Affiliated Employers
because he had no vested interest shall be treated as if he received a
distribution of his entire vested interest and that interest was less than
$3,500.00.

            If a former Member who has a vested interest in his Account received
no distribution or a distribution of less than the full amount of his entire
vested interest as a result of his termination of participation in the Plan, the
nonvested amount in his Account is immediately forfeited following five
consecutive one-year Periods of Severance.

            A distribution shall be treated as if it were made as a result of
termination of participation in the Plan if it is made not later than the end of
the second Plan Year following the Plan Year in which the former Member's
termination occurs.

            7.11 CLAIMS PROCEDURE. When a benefit is due, the Member or
Beneficiary should submit his claim to the person or office designated by the
Committee to receive claims. Under normal circumstances, a final decision shall
be made as to a claim within 90 days after receipt of the claim. If the
Committee notifies the claimant in writing during the initial 90 day period, it
may extend the period up to 180 days after the initial receipt of the claim. The
written notice must contain the circumstances necessitating the extension and
the anticipated date for the final decision. If a claim is denied during the
claims period, the Committee must notify the claimant in writing. The denial
must include the specific reasons for it, the Plan provisions upon which the
denial is based, and the claims review procedure. If no action is taken during
the claims period, the claim is treated as if it were denied on the last day of
the claims period.

            If a Member's or Beneficiary's claim is denied and he wants a
review, he must apply to the Committee in writing. That application may include
any comment or argument the claimant wants to make. The claimant may either
represent himself or appoint a representative, either of whom has the right to
inspect all documents pertaining to the claim and its denial. The Committee may
schedule any meeting with the claimant or his representative that it finds
necessary or appropriate to complete its review.

            The request for review must be filed within 90 days after the
denial. If it is not, the denial becomes final. If a timely request is made, the
Committee must make its decision, under normal circumstances, within 60 days of
the receipt of the request for review. However, if the Committee notifies the
claimant prior to the expiration of the initial review period, it may extend the
period of review up to 120 days following the initial receipt of the request for
a review. All decisions of the Committee must be in writing and must include the
specific reasons for their action and the Plan provisions on which their
decision is based. If a decision is not given to the


                                      VII-6
<PAGE>   37
claimant within the review period, the claim is treated as if it were denied on
the last day of the review period.

            7.12 FORM OF DISTRIBUTIONS. Distributions shall be made only in cash
unless an asset held in the Trust cannot be sold by the distribution date or can
only be sold at less than its appraised value, in which event part or all of the
distribution may be made in kind. A distribution shall be made in a lump sum
payment or, as a Direct Rollover if the Distributee elects, at the time and in
the manner prescribed by the Committee, to have any portion or all of the
Eligible Rollover Distribution paid directly to an Eligible Retirement Plan
named by the Distributee.

            Any benefit held for distribution past one or more Valuation Dates
shall continue to share in the appreciation or depreciation of the Trust Fund
and in the income earned or losses incurred by the Trust Fund until the last
Valuation Date which occurs with or next precedes the date distribution is made.

            If the benefit to be distributed is greater than $3,500.00 and the
Member or former Member consents to the distribution, the benefit should be
distributed or begin to be distributed within one year after the Member or
former Member becomes entitled to the benefit. If the benefit is greater than
$3,500.00 and the Member or former Member fails to consent to the distribution,
the distribution shall not be made without the Member's or former Member's
consent until he attains his Retirement Age or age 62, whichever is later. If
the Member or former Member dies, the surviving spouse may require payments to
begin within a reasonable time.

            7.13 TIME OF DISTRIBUTIONS. Notwithstanding any other provision of
the Plan, all benefits payable under the Plan shall be distributed, or commence
to be distributed, in compliance with the following provisions:

            (a) DISTRIBUTION DEADLINES FOR MEMBERS OR FORMER MEMBERS WHO ARE 70
      1/2 OR OLDER. If a Member or former Member attains 70 1/2, the Member or
      former Member must elect to receive the distribution required under
      section 401(a)(9) of the Code in one lump sum or in installments which
      must commence by his Required Beginning Date. If installments are elected,
      each installment paid must be equal to or greater than the minimum
      required distribution under section 401(a)(9) of the Code.

            (b) DISTRIBUTION DEADLINE FOR DEATH BENEFITS. If a Member or former
      Member dies before the distribution of his Plan benefit has commenced, his
      entire interest shall be distributed within five years after his death. If
      a Member or former Member dies after the distribution of his Plan benefit
      has commenced, the remaining portion of his interest in the Plan, if any,
      will be distributed at least as rapidly as under the installment method of
      distribution selected by him.

            (c) LIMITATIONS ON DEATH BENEFITS. Benefits payable under the Plan
      shall not be provided in any form that would cause a Member's death
      benefit to be more than incidental. Any distribution required to


                                      VII-7
<PAGE>   38
      satisfy the incidental benefit requirement shall be considered a required
      distribution for purposes of section 401(a)(9) of the Code.

            (d) COMPLIANCE WITH SECTION 401(a)(9). All distributions under the
      Plan will be made in accordance with the requirements of section 401(a)(9)
      of the Code and all Regulations promulgated thereunder. The provisions of
      the Plan reflecting section 401(a)(9) of the Code override any
      distribution options in the Plan inconsistent with such Section.

            (e) COMPLIANCE WITH SECTION 401(a)(14). Unless the Member or former
      Member otherwise elects, the payment of benefits under the Plan to the
      Member or former Member will begin not later than the 60th day after the
      close of the Plan Year in which occurs the latest of (a) the date on which
      the Member or former Member attains the later of age 62 or the normal
      retirement age under the Plan, age 65, (b) the 10th anniversary of the
      year in which the Member or former Member commenced participation in the
      Plan, or (c) the Member or former Member Severs Service.


            7.14 DESIGNATION OF BENEFICIARY. Each Member has the right to
designate and to revoke the designation of his Beneficiary or Beneficiaries.
Each designation or revocation must be evidenced by a written document in the
form required by the Committee, signed by the Member and filed with the
Committee. If no designation is on file at the time of a Member's death or if
the Committee determines that the designation is ineffective, the designated
Beneficiary shall be the Member's spouse, if living, or if not, the executor,
administrator or other personal representative of the Member's estate.

            If a Member is considered to be married under local law, the
Member's designation of any Beneficiary, other than the Member's spouse, shall
not be valid unless the spouse acknowledges in writing that he or she
understands the effect of the Member's beneficiary designation and consents to
it. The consent must be to a specific Beneficiary. The written acknowledgement
and consent must be filed with the Committee, signed by the spouse and at least
two witnesses, one of whom must be a member of the Committee or a notary public.
However, if the spouse cannot be located or there exist other circumstances as
described in Sections 401(a)(11) and 417(a)(2) of the Code, the requirement of
the Member's spouse's acknowledgement and consent may be waived. If a
Beneficiary other than the Member's spouse is named, the designation shall
become invalid if the Member is later determined to be married under local law,
the Member's missing spouse is located or the circumstances which resulted in
the waiver of the requirement of obtaining the consent of the Member's spouse no
longer exist.

            7.15 DISTRIBUTIONS TO DISABLED. If the Committee determines that any
person to whom a payment is due is unable to care for his affairs because of
physical or mental disability, it shall have the authority to cause the payments
to be made to the spouse, brother, sister or other person the Committee
determines to have incurred, or


                                      VII-8
<PAGE>   39
to be expected to incur, expenses for that person unless a prior claim is made
by a qualified guardian or other legal representative. The Committee and the
Trustee shall not be responsible to oversee the application of those payments.
Payments made pursuant to this power shall be a complete discharge of all
liability under the Plan and Trust and the obligations of the Employer, the
Trustee, the Trust Fund and the Committee.

                                  ARTICLE VIII

                             TOP-HEAVY REQUIREMENTS


            8.1 APPLICATION. The requirements described in this Article shall
apply to each Plan Year that this Plan is determined to be a Top-Heavy Plan
under the test set out in the following Section.

            8.2 TOP-HEAVY TEST. If on the Determination Date the Aggregate
Accounts of Key Employees in the Plan exceeds 60% of the Aggregate Accounts of
all Employees in the Plan, this Plan shall be a Top-Heavy Plan for that Plan
Year. In addition, if this Plan is required to be included in an Aggregation
Group and that group is a top-heavy group, this Plan shall be treated as a
Top-Heavy Plan. An Aggregation Group is a top-heavy group if on the
Determination Date the sum of (a) the present value of the cumulative accrued
benefits for Key Employees under all defined benefit plans in the Aggregation
Group which contains this Plan, plus (b) the total of all of the accounts of Key
Employees under all defined contribution plans included in the Aggregation Group
(which contains this Plan) is more than 60% of a similar sum determined for all
employees covered in the Aggregation Group which contains this Plan.

            In applying the above tests, the following rules shall apply:

            (a) in determining the present value of the accumulated accrued
      benefits for any Employee or the amount in the account of any Employee,
      the value or amount shall be increased by all distributions made to or for
      the benefit of the Employee under the Plan during the five-year period
      ending on the Determination Date;

            (b) all rollover contributions made after December 31, 1983 by the
      Employee to the plan shall not be considered by the plan for either test;

            (c) if an Employee is a Non-Key Employee under the plan for the Plan
      Year but was a Key Employee under the plan for another prior Plan Year,
      his account shall not be considered; and

            (d) benefits shall not be taken into account in determining the
      top-heavy ratio for any Employee who has not performed services for the
      Employer during the last five-year period ending upon the Determination
      Date.

            8.3 VESTING RESTRICTIONS IF PLAN BECOMES TOP-HEAVY. If a Member has
at least one Hour of Service during a Plan Year when the Plan is a Top-Heavy
Plan, he shall either vest under each of the normal vesting provisions of the
Plan or under the following vesting schedule, whichever is more favorable:

                                                   Percentage of Amount Invested
                                                      In Accounts Containing
Completed Years of Active Service                     Employer Contributions
- ---------------------------------                     ----------------------

<S>                                                            <C>
          Less than two years...............................     0%
          Two years but less than three years...............    20%
          Three years but less than four years..............    40%
          Four years but less than five years...............    60%
          Five years but less than six years................    80%
          Six years or more.................................   100%
</TABLE>

If the Plan ceases to be a Top-Heavy Plan, this requirement shall no longer
apply. After that date, the normal vesting provisions of the Plan shall be
applicable to all subsequent Contributions by the Employer.

            8.4 MINIMUM CONTRIBUTIONS IF PLAN BECOMES TOP-HEAVY. If this Plan is
a Top-Heavy Plan and the normal allocation of the Employer Contribution and
forfeitures is less than 3% of any Non-Key Employee Member's Annual
Compensation, the Committee, without regard to the normal allocation procedures,
shall allocate the Employer Contribution and the forfeitures among the Members
who are in the employ of the Employer at the end of the Plan Year in proportion
to each Member's Annual Compensation as compared to the total Annual
Compensation of all Members for that Plan Year until each Non-Key Employee
Member has had an amount equal to the lesser of (i) the highest rate of
Contribution applicable to any Key Employee, or (ii) 3% of his Annual
Compensation allocated to his Account. At that time, any more Employer
Contributions or forfeitures shall be allocated under the normal allocation
procedures described earlier in this Plan. Salary Deferral Contributions made on
behalf of Key Employees are included in determining the highest rate of Employer
Contributions. Salary Deferral Contributions made on behalf of Non-Key Employees
are not included for that purpose. Amounts that may be treated as Section 401(k)
Contributions made on behalf of Non-Key Employees may not be included in
determining the minimum contribution required under this Section to the extent
that they are treated as Section 401(k) Contributions for purposes of the Actual
Deferral Percentage test.

            In applying this restriction, the following rules shall apply:

            (a) Each Employee who is eligible for membership (without regard to
      whether he has made mandatory contributions, if any are required, or
      whether his compensation is less than a stated amount) shall be entitled
      to receive an allocation under this Section; and

            (b) All defined contribution plans required to be included in the
      Aggregation Group shall be treated as one plan for purposes of meeting the
      3% maximum; this required aggregation shall not apply if this Plan is also
      required to be included in an Aggregation Group which includes a defined
      benefit plan and this Plan enables that defined benefit plan to meet the
      requirements of Sections 401(a)(4) or 410 of the Code.


                                     VIII-2
<PAGE>   42
            8.5 COVERAGE UNDER MULTIPLE TOP-HEAVY PLANS. If this Plan is a
Top-Heavy Plan, it must meet the vesting and benefit requirements described in
this Article without taking into account contributions or benefits under Chapter
2 of the Code (relating to tax on self-employment income), Chapter 21 of the
Code (relating to Federal Insurance Contributions Act), Title II of the Social
Security Act or any other Federal or State law.

            If a Non-Key Employee is covered by both a Top-Heavy defined
contribution plan and a defined benefit plan, he shall receive the defined
benefit minimum, offset by the benefits provided under the defined contribution
plan.

            8.6 RESTRICTIONS IF PLAN BECOMES SUPER TOP-HEAVY. If the Plan is
determined to be a Top-Heavy Plan, the number "1.00" must be substituted for the
number "1.25" when applying the limitations of Section 415 of the Code to this
Plan, unless the Plan would not be a Top-Heavy Plan if "90%" were substituted
for "60%" and the Employer Contribution for the Plan Year for each Non-Key
Employee, who is a Member, is not less than 4% of the Member's Annual
Compensation.

            (f) To determine all controversies relating to the administration of
      the Plan and Trust, including but not limited to any differences of

<PAGE>   44
            (i) To delegate any clerical or recordation duties of the Committee
      as the Committee believes is advisable to properly administer the Plan and
      Trust.

The actions of the Committee in exercising all of the rights, powers, and
authorities set out in this Section and all other Sections of this Plan, when
performed in good faith and in its sole judgment, shall be final, conclusive and
binding on all parties.

            9.3 ORGANIZATION. The Committee may select, from among its members,
a chairman, and may select a secretary. The secretary need not be a member of
the Committee. The secretary shall keep all records, documents and data
pertaining to its administration of the Plan and Trust.

            9.4 QUORUM AND MAJORITY ACTION. A majority of the Committee
constitutes a quorum for the transaction of business. The vote of a majority of

meeting. In addition, the Committee may decide any question by a vote, taken
without a meeting, of a majority of its members.

            9.5 SIGNATURES. The chairman, the secretary and any one or more of
the members of the Committee to which the Committee has delegated the power
shall each, severally, have the power to execute any document on behalf of the
Committee, and to execute any certificate or other written evidence of the
action of the Committee. The Trustee, after it is notified of any delegation of
power in writing, shall accept and may rely upon any document executed by the
appropriate member or members as representing the action of the Committee until
the Committee files a written revocation of that delegation of power with the
Trustee.

            9.6 DISQUALIFICATION OF COMMITTEE MEMBER. A member of the Committee
who is also a Member of this Plan shall not vote or act upon any matter relating
solely to himself.

            9.7 DISCLOSURE TO MEMBERS. The Committee shall make available to
each Member and Beneficiary for his examination those records, documents and
other data required under ERISA, but only at reasonable times during business
hours. No Member or Beneficiary has the right to examine any data or records
reflecting the compensation paid to any other Member or Beneficiary. The
Committee is not required to make any other data or records available other than
those required by ERISA.

            9.8 STANDARD OF PERFORMANCE. The Committee and each of its members
shall use the care, skill, prudence and diligence under the circumstances then
prevailing that a prudent man, acting in a like capacity and familiar with such
matters, would use in conducting his business as the administrator of the Plan,
shall, when exercising its power to direct investments, diversify the
investments of the Plan so as to minimize the risk of large losses, unless under
the circumstances it is clearly prudent not to do so, and shall otherwise comply
with the provisions of this Plan and ERISA.


                                      IX-2
<PAGE>   45
            9.9 LIABILITY OF COMMITTEE AND LIABILITY INSURANCE. No member of the
Committee shall be liable for any act or omission of any other member of the
Committee, the Trustee, any investment manager appointed by the Committee or any
other agent appointed by the Committee unless required by the terms of ERISA or
another applicable state or federal law under which liability cannot be waived.
No member of the Committee shall be liable for any act or omission of his own
unless required by ERISA or another applicable state or federal law under which
liability cannot be waived.

            If the Committee directs the Trustee to do so, it may purchase out
of the Trust Fund insurance for the members of the Committee, for any other
fiduciaries appointed by the Committee and for the Trust Fund itself to cover
liability or losses occurring because of the act or omission of any one or more
of the members of the Committee or any other fiduciary appointed under this
Plan. But, that insurance must permit recourse by the insurer against the
members of the Committee or the other fiduciaries concerned if the loss is
caused by breach of a fiduciary obligation by one or more members of the
Committee or other fiduciary.

            9.10 EXEMPTION FROM BOND. No member of the Committee is required to
give bond for the performance of his duties unless required by a law which
cannot be waived.

            9.11 COMPENSATION. The Committee shall serve without compensation
but shall be reimbursed by the Employer for all expenses properly incurred in
the performance of their duties unless the Sponsor elects to have those expenses
paid from the Trust Fund. Each Employer shall pay that part of the expense as
determined by the Committee in its sole judgment.

            9.12 PERSONS SERVING IN DUAL FIDUCIARY ROLES. Any person, group of
persons, corporations, firm or other entity, may serve in more than one
fiduciary capacity with respect to this Plan, including serving as both Trustee
and as a member of the Committee.

            9.13 ADMINISTRATOR. For all purposes of ERISA, the administrator of
the Plan is the Sponsor. The administrator has the final responsibility for
compliance with all reporting and disclosure requirements imposed under all
applicable federal or state laws and regulations.

                          TRUST FUND AND CONTRIBUTIONS


            10.1 FUNDING OF PLAN. This Plan shall be funded by one or more
separate Trusts. If more than one Trust is used, each Trust shall be designated
by the name of the Plan followed by a number assigned by the Committee at the
time the Trust is established.

            10.2 INCORPORATION OF TRUST. Each Trust is a part of this Plan. All
rights or benefits which accrue to a person under this Plan shall be subject
also to the terms of the agreements creating the Trust or Trusts and any
amendments to them which are not in direct conflict with this Plan.

            10.3 AUTHORITY OF TRUSTEE. Each Trustee shall have full title and
legal ownership of the assets in the separate Trust which, from time to time, is
in his separate possession. No other Trustee shall have joint title to or joint
legal ownership of any asset in one of the other Trusts held by another Trustee.
Each Trustee shall be governed separately by the trust agreement entered into
between the Employer and that Trustee and the terms of this Plan without regard
to any other agreement entered into between any other Trustee and the Employer
as a part of this Plan.

            10.4 ALLOCATION OF RESPONSIBILITY. To the fullest extent permitted
under Section 405 of ERISA, the agreements entered into between the Employer and
each of the Trustees shall be interpreted to allocate to each Trustee its
specific responsibilities, obligations and duties so as to relieve all other
Trustees from liability either through the agreement, this Plan or ERISA, for
any act of any other Trustee which results in a loss to the Plan because of his
act or failure to act.

                                   ARTICLE XI

                       ADOPTION OF PLAN BY OTHER EMPLOYERS


            11.1 ADOPTION PROCEDURE. Any business organization may, with the
approval of the Board of Directors, adopt this Plan by:

            (a) A certified resolution or consent of the board of directors of
      the adopting Employer or an executed adoption instrument (approved by the
      board of directors of the adopting Employer) agreeing to be bound as an
      Employer by all the terms, conditions and limitations of this Plan except
      those, if any, specifically described in the adoption instrument; and

            (b) Providing all information required by the Committee and the
      Trustee.

            An adoption may be retroactive to the beginning of a Plan Year if
these conditions are complied with on or before the last day of that Plan Year.

            11.2 NO JOINT VENTURE IMPLIED. The document which evidences the
adoption of the Plan by an Employer shall become a part of this Plan. However,
neither the adoption of this Plan and its related Trust Fund by an Employer nor
any act performed by it in relation to this Plan and its related Trust Fund
shall ever create a joint venture or partnership relation between it and any
other Employer.

            11.3 ALL TRUST ASSETS AVAILABLE TO PAY ALL BENEFITS. The Accounts of
Members employed by the Employers which adopt this Plan shall be commingled for
investment purposes. All assets in the Trust Fund shall be available to pay
benefits to all Members employed by any Employer which is an Affiliated Employer
with the first Employer.

            11.4 QUALIFICATION A CONDITION PRECEDENT TO ADOPTION AND CONTINUED
PARTICIPATION. The adoption of this Plan and the Trust or Trusts used to fund
this Plan by a business organization is contingent upon and subject to the
express condition precedent that the initial adoption meets all statutory and
regulatory requirements for qualification of the Plan and the exemption of the
Trust or Trusts and that the Plan and the Trust or Trusts that are applicable to
it continue in operation to maintain their qualified and exempt status. In the
event the adoption fails to initially qualify and be exempt, the adoption shall
fail retroactively for failure to meet the condition precedent and the portion
of the Trust Fund applicable to the adoption shall be immediately returned to
the adopting business organization and the adoption shall be void ab initio. In
the event the adoption as to a given business organization later becomes
disqualified and loses its exemption for any reason, the adoption shall fail
retroactively for failure to meet the condition precedent and the portion of the
Trust Fund allocable to the adoption by that business organization shall be
immediately spun off, retroactively as of the last date for which the Plan
qualified, to a separate Trust for its sole benefit and an identical but
separate Plan shall be created, retroactively effective as of the last date


                                      XI-1
<PAGE>   48
the Plan as adopted by that business organization qualified, for the benefit of
the Members covered by that adoption.

                            AMENDMENT AND TERMINATION


            12.1 RIGHT TO AMEND AND LIMITATIONS THEREON. The Sponsor has the
sole right to amend this Plan. An amendment may be made by a certified
resolution or consent of the Board of Directors, or by an instrument in writing
executed by the appropriate officer of the Sponsor. The amendment must describe
the nature of the amendment and its effective date. No amendment shall:

            (a) Vest in an Employer any interest in the Trust Fund;

            (b) Cause or permit the Trust Fund to be diverted to any purpose
      other than the exclusive benefit of the present or future Members and
      their Beneficiaries except under the circumstances described in Section
      4.8;

            (c) Decrease the Account of any Member or eliminate an optional form
      of payment;

            (d) Increase substantially the duties or liabilities of the Trustee
      without its written consent; or

            (e) Change the vesting schedule to one which would result in the
      nonforfeitable percentage of the Account derived from Employer
      Contributions (determined as of the later of the date of the adoption of
      the amendment or of the effective date of the amendment) of any Member
      being less than the nonforfeitable percentage computed under the Plan
      without regard to the amendment. If the Plan's vesting schedule is
      amended, if the Plan is amended in any other way that affects the
      computation of the Member's nonforfeitable percentage, or if the Plan is
      deemed amended by an automatic change to or from a Top-Heavy vesting
      schedule, each Member with at least three years of Service may elect,
      within a reasonable period after the adoption of the amendment or the
      change, to have the nonforfeitable percentage computed under the Plan
      without regard to the amendment or the change. The election period shall
      begin no later than the date the amendment is adopted or deemed to be made
      and shall end no later than the latest of the following dates: (1) 60 days
      after the date the amendment is adopted or deemed to be made, (2) 60 days
      after the date the amendment becomes effective, or (3) 60 days after the
      day the Member is issued written notice of the amendment.

            Each Employer shall be deemed to have adopted any amendment made by
the Sponsor unless the Employer notifies the Committee of its rejection in
writing within 30 days after it receives a copy of the amendment. A rejection
shall constitute


                                      XII-1
<PAGE>   50
a withdrawal from this Plan by that Employer unless the Sponsor acquiesces in
the rejection.

            12.2 MANDATORY AMENDMENTS. The Contributions of each Employer to
this Plan are intended to be:

            (a) Deductible under the applicable provisions of the Code;

            (b) Except as otherwise prescribed by applicable law, exempt from
      the Federal Social Security Act;

            (c) Except as otherwise prescribed by applicable law, exempt from
      withholding under the Code; and

            (d) Excludable from any Employee's regular rate of pay, as that term
      is defined under the Fair Labor Standards Act of 1938, as amended.

            The Sponsor shall make any amendment necessary to carry out this
intention, and it may be made retroactively.

            12.3 WITHDRAWAL OF EMPLOYER. An Employer may withdraw from this Plan
and its related Trust Fund if the Sponsor does not acquiesce in its rejection of
an amendment or by giving written notice of its intent to withdraw to the
Committee. The Committee shall then determine the portion of the Trust Fund that
is attributable to the Members employed by the withdrawing Employer and shall
notify the Trustee to segregate and transfer those assets to the successor
Trustee or Trustees when it receives a designation of the successor from the
withdrawing Employer.

            A withdrawal shall not terminate the Plan and its related Trust Fund
with respect to the withdrawing Employer, if the Employer either appoints a
successor Trustee or Trustees and reaffirms this Plan and its related Trust Fund
as its new and separate plan and trust intended to qualify under Section 401(a)
of the Code, or establishes another plan and trust intended to qualify under
Section 401(a) of the Code.

            The determination of the Committee, in its sole discretion, of the
portion of the Trust Fund that is attributable to the Members employed by the
withdrawing Employer shall be final and binding upon all parties; and, the
Trustee's transfer of those assets to the designated successor Trustee shall
relieve the Trustee of any further obligation, liability or duty to the
withdrawing Employer, the Members employed by that Employer and their
Beneficiaries, and the successor Trustee or Trustees.

            12.4 TERMINATION OF PLAN. The Sponsor may terminate this Plan and
its related Trust Fund with respect to all Employers by executing and delivering
to the Committee and the Trustee, a notice of termination, specifying the date
of termination. Any Employer may terminate this Plan and its related Trust Fund
with respect to itself by executing and delivering to the Trustee a notice of
termination, specifying the date of termination. Likewise, this Plan and its
related Trust Fund shall automatically terminate with respect to any Employer if
there is a general assignment by that


                                      XII-2
<PAGE>   51
Employer to or for the benefit of its creditors, or a liquidation or dissolution
of that Employer without a successor. Upon the termination of this Plan as to an
Employer, the Trustee shall distribute to each Member employed by the
terminating Employer the amount certified by the Committee to be due the Member.

            The Employer should apply to the Internal Revenue Service for a
determination letter with respect to its termination, and the Trustee should not
distribute the Trust Funds until a determination is received. However, should it
decide that a distribution before receipt of the determination letter is
necessary or appropriate it should retain sufficient assets to cover any tax
that may become due upon that determination.

            12.5 PARTIAL OR COMPLETE TERMINATION OR COMPLETE DISCONTINUANCE OF
CONTRIBUTIONS. Without regard to any other provision of this Plan, if there is a
partial or total termination of this Plan or there is a complete discontinuance
of the Employer's Contributions, each of the affected Members shall immediately
become 100% vested in his Account as of the end of the last Plan Year for which
a substantial Employer Contribution was made and in any amounts later allocated
to his Account. If the Employer then resumes making substantial Contributions at
any time, the appropriate vesting schedule shall again apply to all amounts
allocated to each affected Member's Account beginning with the Plan Year for
which they were resumed.

            12.6 CONTINUANCE PERMITTED UPON SALE OR TRANSFER OF ASSETS. An
Employer's participation in this Plan and its related Trust Fund shall not
automatically terminate if it consolidates or merges and is not the surviving
corporation, sells substantially all of its assets, is a party to a
reorganization and its Employees and substantially all of its assets are
transferred to another entity, liquidates, or dissolves, if there is a successor
organization. Instead, the successor may assume and continue this Plan and its
related Trust Fund by executing a direction, entering into a contractual
commitment or adopting a resolution providing for the continuance of the Plan
and its related Trust Fund. Only upon the successor's rejection of this Plan and
its related Trust Fund or its failure to respond to the Employer's, the
Sponsor's or the Trustee's request that it affirm its assumption of this Plan
within 90 days of the request shall this Plan automatically terminate. In that
event the appropriate portion of the Trust Fund shall be distributed exclusively
to the Members or their Beneficiaries as soon as possible. If there is a
disposition to an unrelated entity of substantially all of the assets used by
the Employer in a trade or business or a disposition by the Employer of its
interest in a subsidiary, the Employer may make a lump sum distribution from the
Plan if it continues the Plan after the disposition; but the distribution can
only be made for those Members who continue employment with the acquiring
entity.

            12.7 DISTRIBUTIONS UPON TERMINATION OF THE PLAN. A Member is
entitled to receive a lump sum distribution on account of the termination of the
Plan if the Employer and all Affiliated Employers do not establish or maintain a
successor plan within the period ending 12 months after all assets are
distributed from the Plan. A distribution on account of the termination of the
Plan may be made only in the form of a lump sum payment. Therefore, if a
Member's Account balance plus all prior Plan


                                      XII-3
<PAGE>   52
payments to the Member is more than $3,500 and the Member does not consent to
receive an immediate lump sum payment on account of the termination of the Plan
the Member will not receive a Plan distribution on account of the termination of
the Plan. His Plan benefit will be payable in the future on account of a
distribution event other than the termination of the Plan.

            If the Plan is terminated and does not offer an annuity option
(purchased from a commercial provider) and the Employer or an Affiliated
Employer maintains another defined contribution plan the Member's Account
balance may be transferred to the other plan without his consent if he does not
consent to an immediate lump sum distribution from the Plan.

            For purposes of this Section the term "successor plan" means a
defined contribution plan other than an employee stock ownership plan as defined
in section 4975(e) or 409 of the Code or a simplified employee pension plan as
defined in section 408(k) of the Code. However, the term successor plan does not
include any plan in which fewer than two percent of the Plan Members were
eligible to participate during the 24 month period beginning 12 months before
the time of Plan termination.

                                  MISCELLANEOUS


            13.1 PLAN NOT AN EMPLOYMENT CONTRACT. The adoption and maintenance
of this Plan and its related Trust Fund is not a contract between any Employer
and its Employees which gives any Employee the right to be retained in its
employment. Likewise, it is not intended to interfere with the rights of any
Employer to discharge any Employee at any time or to interfere with the
Employee's right to terminate his employment at any time.

            13.2 BENEFITS PROVIDED SOLELY FROM TRUST. All benefits payable under
this Plan shall be paid or provided for solely from the Trust Fund. No Employer
assumes any liability or responsibility to pay any benefit provided by the Plan.

            13.3 ANTI-ALIENATION PROVISIONS. No principal or income payable or
to become payable from the Trust Fund shall be subject: to anticipation or
assignment by a Member or by a Beneficiary to attachment by, interference with,
or control of any creditor of a Member or Beneficiary, or to being taken or
reached by any legal or equitable process in satisfaction of any debt or
liability of a Member or Beneficiary prior to its actual receipt by the Member
or Beneficiary. An attempted conveyance, transfer, assignment, mortgage, pledge,
or encumbrance of the Trust Fund, any part of it, or any interest in it by a
Member or Beneficiary prior to distribution shall be void, whether that
conveyance, transfer, assignment, mortgage, pledge, or encumbrance is intended
to take place or become effective before or after any distribution of Trust
assets or the termination of this Trust Fund itself. The Trustee shall never
under any circumstances be required to recognize any conveyance, transfer,
assignment, mortgage, pledge or encumbrance by a Member or Beneficiary of the
Trust Fund, any part of it, or any interest in it, or to pay any money or thing
of value to any creditor or assignee of a Member or Beneficiary for any cause
whatsoever. These prohibitions against the alienation of a Member's Account
shall not apply to qualified domestic relations orders or domestic relations
orders entered prior to January 1, 1985.

            13.4 REQUIREMENTS UPON MERGER OR CONSIDERATION OF PLANS. This Plan
shall not merge or consolidate with or transfer any assets or liabilities to any
other plan unless each Member would (if the Plan then terminated) receive a
benefit immediately after the merger, consolidation, or transfer which is equal
to or greater than the benefit he would have been entitled to receive
immediately before the merger, consolidation, or transfer (if the Plan had then
terminated).

            13.5 GENDER OF WORDS USED. If the context requires it, words of one
gender when used in this Plan shall include the other genders, and words used in
the singular or plural shall include the other.

            13.6 SEVERABILITY. Each provision of this Agreement may be severed.
If any provision is determined to be invalid or unenforceable, that
determination shall not affect the validity or enforceability of any other
provision.

            13.7 REEMPLOYED VETERANS. The requirements of the Uniformed Services
Employment and Reemployment Rights Act of 1994 will be complied with in the
operation of the Plan in the manner permitted under section 414(u) of the Code.

            13.8 GOVERNING LAW; PARTIES TO LEGAL ACTIONS. The provisions of this
Plan shall be construed, administered, and governed under the laws of the State
of Texas and, to the extent applicable, by the laws of the United States. The
Trustee or any Employer may at any time initiate a legal action or proceeding
for the settlement of the account of the Trustee, or for the determination of
any question or for instructions. The only necessary parties to that action or
proceeding are the Trustee and the Employer concerned. However, any other person
or persons may be included as parties defendant at the election of the Trustee
and the Employer.

<PAGE>   7
SECTION 4. INVESTMENT OF TRUST.

         (a)   Selection of Investment Options.  The Trustee shall have no
responsibility for the selection of investment options under the Trust and

offer as investment options only (i) securities issued by the investment
companies advised by Fidelity Management & Research Company ("Mutual Funds"),

<PAGE>   8
made by Plan participants by use of the telephone exchange system maintained
for such purposes by the Trustee or its agent, in accordance with written
Telephone Exchange Guidelines attached hereto as Schedule "G". If a Plan
participant makes an oral investment via the telephone exchange system, the
Trustee will return to that participant a written confirmation of that
direction. Any directions made by a Participant using the telephone exchange
system shall be treated as a direction made in writing by the Named Fiduciary
for purposes of Section 7 hereafter. In the event that the Trustee fails to
receive a proper direction, the assets shall be invested in the securities of
the Mutual Fund set forth for such purpose on Schedule "C", until the Trustee
receives a proper direction.

to the following limitations:

documentation necessary to accurately effect such purchases and sales (or in
the case of a purchase, the subsequent date on which the Trustee has received a
wire transfer of funds necessary to make such purchase). Exchanges of Mutual
Funds shall be made in accordance with the Telephone Exchange Guidelines
attached hereto as Schedule "G".

or special stockholders' meeting of any Mutual Fund, the Trustee shall send a
copy of the notice and all proxy solicitation materials to each Plan
participant who has shares of the Mutual Fund credited to the participant's
accounts, together with a voting direction form for return to the Trustee or
its designee. The

which the Trustee is to vote the shares credited to the participant's accounts
(both vested and unvested). The Trustee shall vote the shares as directed by
the participant. The Trustee shall not vote shares for which it has received no
directions from the participant. With respect to all rights other than the
right to vote, the Trustee shall follow the directions of the participant and

fiduciary duty rules of section 404(a)(1) of ERISA (as modified by section
404(a)(2) of ERISA) of acquiring and holding Sponsor Stock.  The Trustee shall
not be liable for any loss, or by reason of any breach, which arises from the
directions of the Administrative Committee or Plan Participants  with respect

face that the actions to be taken under those directions would be prohibited by
the foregoing fiduciary duty rules or would be contrary to the terms of the
Plan or this Agreement.

than for exchanges) shall be made on the open market on the date on which the
Trustee receives from the Administrator in good order all information,
documentation, and wire transfer of funds (if applicable), necessary to
accurately effect such transactions.   Exchanges of Sponsor Stock shall be made
in accordance with the Telephone Exchange Guidelines attached hereto as
Schedule "G".  Such general rules shall not apply in the following
circumstances:

                                  (1)       If the Trustee is unable to
determine the number of shares required to be purchased or sold on such day; or

                                  (2)      If the Trustee is unable to purchase
or sell the total number of shares required to be purchased or sold on such day
as a result of market conditions; or

                                  (3)      If the Trustee is prohibited by the
Securities and Exchange Commission, the New York Stock Exchange, or any other
regulatory body from purchasing or selling any or all of the shares required to
be purchased or sold on such day.

In the event of the occurrence of the circumstances described in (1), (2) or
(3) above, the Trustee shall purchase or sell such shares as soon as possible
thereafter and shall determine the price of such purchases or sales to be the
average purchase or sales price of all such shares purchased or sold,
respectively.  The Trustee may follow directions from the Administrative
Committee to deviate from the above purchase and sale procedures provided that
such direction is made in writing by the Administrative Committee.

such directions directly or through its affiliate, National Financial Services

cents ($.04) commission on each share of Sponsor Stock from 10,001 to 20,000
shares in a singular transaction, and three and one-half cents ($.035)
commission on each share of Sponsor Stock in excess of 20,000 shares in a
singular transaction.  Any change in such remuneration may be made only by a
signed agreement between Sponsor and Trustee.

                                  (2)  Following the procedures set forth in
Department of Labor Prohibited Transaction Class Exemption 86-128 (PTCE
86-128), the Trustee will provide the Sponsor with the following documents: (1)
a description of FBSI's brokerage placement practices; (2) a copy of PTCE
86-128; and (3) a form by which the Sponsor may terminate this authorization to
use a broker affiliated with the Trustee.  The Trustee will, within the time
periods specified in PTCE 86-128, provide the Sponsor with the confirmations
and reports required under PTCE 86-128.

                                  (3)      Any successor organization of FBSI,
through reorganization, consolidation, merger or similar transactions, shall,
upon consummation of such





                                       8
<PAGE>   12
transaction, become the successor broker in accordance with the terms of this
authorization provision.

                                  (4)  The Trustee and FBSI shall continue to
rely on this authorization provision until notified to the contrary.  The
Sponsor reserves the right to terminate this authorization upon written notice
to FBSI (or its successor) and the Trustee, in accordance with Section 11 of
this Agreement.

                                  (iv)  Securities Law Reports.  The
Administrator shall be responsible for filing all reports required under
Federal or state securities laws with respect to the Trust's ownership of
Sponsor Stock, including, without limitation, any reports required under
section 13 or 16 of the Securities Exchange Act of 1934, and shall immediately
notify the Trustee in writing of any requirement to stop purchases or sales of
Sponsor Stock pending the filing of any report.  The Trustee shall provide to
the Administrator such information on the Trust's ownership of Sponsor Stock as
the Administrator may reasonably request in order to comply with Federal or
state securities laws.

                                  (v)  Voting and Tender Offers.
Notwithstanding any other provision of this Agreement the provisions of this
Section shall govern the voting and tendering of Sponsor Stock.  The Sponsor,
after consultation with the Trustee, shall pay for all printing, mailing,
tabulation and other costs associated with the voting and tendering of Sponsor
Stock.


                          (A)     Voting.

                                  (1)  When the issuer of Sponsor Stock
prepares for any annual or special meeting, the Sponsor shall notify the
Trustee at least thirty (30) days in advance of the





                                       9
<PAGE>   13
intended record date and shall cause a copy of all proxy solicitation materials
to be sent to the Trustee.  If requested by the Trustee the Sponsor shall
certify to the Trustee that the aforementioned materials represents the same
information distributed to shareholders of Sponsor Stock.  Based on these
materials the Trustee shall prepare a voting instruction form and shall provide
a copy of   all proxy solicitation materials to be sent to each Plan
participant, together with the foregoing voting instruction form to be returned
to the Trustee or its designee.  The form shall show the number of full and
fractional shares of Sponsor Stock credited to the participant's accounts.

                                  (2)  Each participant shall have the right to
direct the Trustee as to the manner in which the Trustee is to vote that number
of shares of Sponsor Stock credited to the participant's accounts (both vested
and unvested).  Directions from a participant to the Trustee concerning the
voting of Sponsor Stock shall be communicated in writing, or by mailgram or
similar means as agreed upon by the Trustee and the Sponsor.  These directions
shall be held in confidence by the Trustee and shall not be divulged to the
Sponsor, or any officer or employee thereof, or any other person except to the
extent that the consequences of such directions are reflected in reports
regularly communicated to any such person in the ordinary course of the
performance of the Trustee's services hereunder.  Upon its receipt of the
directions, the Trustee shall vote the shares of Sponsor Stock as directed by
the participant.  The Trustee shall vote shares of Sponsor Stock credited to
participant's account for which it has received no directions from the
participant in the same proportion on each issue as it votes those shares for
which it received voting instructions from participants.





                                       10
<PAGE>   14
                                  (3)  The Trustee shall vote that number of
shares of Sponsor Stock not credited to participants' accounts which is
determined by multiplying the total number of shares not credited to
participant's accounts by a fraction of which the numerator is the number of
shares of Sponsor Stock credited to participant's accounts for which the
Trustee received voting directions from participants and of which the
denominator is the total number of shares of Sponsor Stock credited to
participant's accounts.  The Trustee shall vote those shares of Sponsor Stock
not credited to participant's accounts which are to be voted by the Trustee
pursuant to the foregoing formula in the same proportion on each issue as it
votes those shares credited to participants' accounts for which it received
voting directions from participants.  The Trustee shall not vote the remaining
shares of Sponsor Stock not credited to participant's accounts.


                          (B)     Tender Offers.

                                  (1)  Upon commencement of a tender offer for
any securities held in the Trust that are Sponsor Stock, the Sponsor shall
timely notify the Trustee in advance of the intended tender date and shall
cause a copy of all materials to be sent to the Trustee.  The Sponsor shall
certify to the Trustee that the aforementioned materials represent the same
information distributed to shareholders of Sponsor Stock.  Based on these
materials and after consultation with the Sponsor, the Trustee shall prepare a
tender instruction form and shall provide a copy of all tender materials to be
sent to each plan participant, together with the foregoing tender instruction
form, to be returned to the Trustee or its designee.  The tender instruction
form shall show the number of full and fractional shares of Sponsor Stock
credited to the participants account (both vested and unvested).





                                       11
<PAGE>   15
                                  (2)  Each participant shall have the right to
direct the Trustee to tender or not to tender some or all of the shares of
Sponsor Stock credited to the participant's accounts (both vested and
unvested).  Directions from a participant to the Trustee concerning the tender
of Sponsor Stock shall be communicated in writing, or by mailgram or such
similar means as is agreed upon by the Trustee and the Sponsor.  These
directions shall be held in confidence by the Trustee and shall not be divulged
to the Sponsor, or any officer or employee thereof, or any other person except
to the extent that the consequences of such directions are reflected in reports
regularly communicated to any such persons in the ordinary course of the
performance of the Trustee's services hereunder.  The Trustee shall tender or
not tender shares of Sponsor Stock as directed by the participant.  The Trustee
shall not tender shares of Sponsor Stock credited to a participant's accounts
for which it has received no directions from the participant.

                                  (3)  The Trustee shall tender that number of
shares of Sponsor Stock not credited to participants' accounts which is
determined by multiplying the total number of shares of Sponsor Stock not
credited to participants' accounts by a fraction of which the numerator is the
number of shares of Sponsor Stock credited to participants' accounts for which
the Trustee has received directions from participants to tender (which
directions have not been withdrawn as of the date of this determination) and of
which the denominator is the total number of shares of Sponsor Stock credited
to participants' accounts.

                                  (4)  A participant who has directed the
Trustee to tender some or all of the shares of Sponsor Stock credited to the
participant's accounts may, at any time prior to the tender offer withdrawal
date, direct the Trustee to withdraw some or all of the tendered shares, and
the Trustee shall withdraw the directed number of shares from the tender offer
prior





                                       12
<PAGE>   16
to the tender offer withdrawal deadline.  Prior to the withdrawal deadline, if
any shares of Sponsor Stock not credited to participants' accounts have been
tendered, the Trustee shall redetermine the number of shares of Sponsor Stock
that would be tendered under Section 4(e)(v)(B)(3) if the date of the foregoing
withdrawal were the date of determination, and withdraw from the tender offer
the number of shares of Sponsor Stock not credited to participants' accounts
necessary to reduce the amount of tendered Sponsor Stock not credited to
participants' accounts to the amount so redetermined.  A participant shall not
be limited as to the number of directions to tender or withdraw that the
participant may give to the Trustee.

                                  (5)  A direction by a participant to the
Trustee to tender shares of Sponsor Stock credited to the participant's
accounts shall not be considered a written election under the Plan by the
participant to withdraw, or have distributed, any or all of his withdrawable
shares.  The Trustee shall credit to each account of the participant from which
the tendered shares were taken the proceeds received by the Trustee in exchange
for the shares of Sponsor Stock tendered from that account.  Pending receipt of
directions (through the Administrator) from the participant or the Named
Fiduciary, as provided in the Plan, as to which of the remaining investment
options the proceeds should be invested in, the Trustee shall invest the
proceeds in the investment option described in Schedule "C".

                          (vi)     Shares Credited  For all purposes of this
Section, the number of shares of Sponsor Stock deemed "credited" to a
participant's accounts shall be determined as of the relevant date (the record
date or the date specified in the tender offer) shall be calculated by
reference to the number of shares reflected on the books of the transfer agent
as of the relevant





                                       13
<PAGE>   17
date,  In the case of a tender offer, the number of shares credited shall be
determined as of a date as close as administratively feasible to the relevant
date.

                          (vii)   General.  With respect to all rights other
than the right to vote, the right to tender, and the right to withdraw shares
previously tendered, in the case of Sponsor Stock credited to a participant's
accounts, the Trustee shall follow the directions of the participant and if no
such directions are received, the directions of the Named Fiduciary.  The
Trustee shall have no duty to solicit directions from participants.  With
respect to all rights other than the right to vote and the right to tender, in
the case of  Sponsor Stock not credited to participants' accounts, the Trustee
shall follow the directions of the Named Fiduciary.

                 (viii)   Conversion.  All provisions in this Section 4(e)
shall also apply to any securities received as a result of a conversion of
Sponsor Stock.


         (f)    Notes   The Administrator shall act as the Trustee's agent for
the purpose of holding all trust investments in participant loan notes and
related documentation and as such shall (i) hold physical custody of and keep
safe the notes and other loan documents, (ii) collect and remit all principal
and interest payments to the Trustee, (iii) keep the proceeds of such loans
separate from the other assets of the Administrator and clearly identify such
assets as Plan assets and (iv) cancel and surrender the notes and other loan
documentation when a loan has been paid in full.  To originate a participant
loan, the Plan participant shall notify the Trustee of the request by use of
the Telephone Exchange System.  The trustee shall determine, based on the
current value of the Plan participant's account, the amount available for the
loan.  The Plan participant shall then direct the Trustee regarding the amount
to be borrowed and the term or period for repayment.





                                       14
<PAGE>   18
Based on the most recent interest rate supplied by the Sponsor in accordance
with the terms of the Plan, the Trustee shall advise the Plan participant of
such interest rate, as well as the installment payment amounts.  The Trustee
shall forward the loan document to the Plan participant for execution and
submission for approval to the Administrator.  The Administrator shall have the
responsibility for instructing the Trustee as to whether the Administrator has
approved the loan.  The Trustee shall send the loan proceeds to the
Administrator or to the Plan participant in accordance with the directions form
the Administrator.  In all cases, such approval by the Administrator shall be
made within 30 days of the Plan participant's initial request (the origination
date).

         (g)  Commingled Pool Investments   To the extent that the
Administrative Committee of the Plan selects as an investment option the
Managed Income Portfolio of the Fidelity Group Trust for Employee Benefit Plans
(the "Group Trust"), the Sponsor hereby (A) agrees to the terms of the Group
Trust and adopts that it has received from the Trustee a copy of the Group
Trust, the Declaration of Separate Fund for the Managed Income Portfolio of the
Group Trust, and the Circular for the Managed Income Portfolio.



         (h)   Reliance of Trustee on Directions.  (i) The Trustee shall not be
liable for any loss, or by reason of any breach, which arises from any
participant's exercise or non-exercise of rights under this Section 4 over the
assets in the participant's accounts.  (ii)  The Trustee shall not be liable
for any loss, or by reason of any breach, which arises from the Administrative
Committee's exercise or non-exercise of rights under this Section 4, unless it
was clear on their face that the actions to be taken under the Administrative
Committee's directions were prohibited by the





                                       15

4, to sell, exchange, convey, transfer, or otherwise dispose of any property

other property delivered to the Trustee or to inquire into the validity,
expediency, or propriety of any such sale or other disposition.

interest bearing accounts with the Trustee or money market mutual funds advised
by affiliates of the Trustee) and in collective investment funds maintained by
the Trustee for qualified plans, in which case the provisions of each
collective investment fund in which the Trust is invested shall be deemed
adopted by the Sponsor and the provisions thereof incorporated as a part of
this Trust as long as the fund remains exempt from taxation under Sections
401(a) and 501(a) of the Internal Revenue Code of 1986, as amended.

                 (iii)     To cause any securities or other property held as
part of the Trust to be registered in the Trustee's own name, in the name of

paid by the Sponsor.

                 (viii)     To do all other acts that are in accordance with
the powers granted to the Trustee under common law, the applicable state trust
law and other applicable statutes.

                 (ix)      The Trustee is not required to take any legal action
to collect, preserve or maintain any Trust property unless it has been

otherwise required under ERISA, upon the expiration of six (6) months from the
date of filing such account with the Administrator, the Trustee shall have no
liability or further accountability to anyone with respect to the propriety of
its acts or transactions shown in such account, except with respect to such

         (c)   Inspection and Audit. All records generated by the Trustee in

terms of the Plan or this Agreement.

         (c)   Directions from Named Fiduciary. Whenever the Named Fiduciary or

believes the signature of the individual to be genuine, unless it is clear on
the direction's face that the actions to be taken under the direction would be
prohibited by the fiduciary duty rules of section 404(a) of ERISA or would be
contrary to the terms of the Plan or this Agreement.

         (d)   Co-Fiduciary Liability.  In any other case, the Trustee shall

litigation arising from any act done or omitted to be done by any individual or
person with respect to the Plan or Trust, excepting only any and all loss,
etc., arising from the Trustee's breach of its fiduciary duties under ERISA.

calendar year amend Schedule "B" without the Sponsor's consent upon
seventy-five (75) days written notice to the Sponsor.



SECTION 14. GENERAL.

         (a)   Employment of Affiliates as Agents for Trustee. The Sponsor
acknowledges and authorizes that the Trustee may employ its affiliates to act
as its agent in the performance of its responsibilities under this Agreement.
In particular, the Sponsor specifically acknowledges and authorizes that the
Trustee may employ Fidelity Investments Institutional Operations Company or its
successor to perform recordkeeping functions under this Agreement. The expenses
and compensation of any such agent shall be paid by the Trustee out of its fees
described in Schedule "B" attached hereto.

         (b)   Entire Agreement.  This Agreement contains all of the terms
agreed upon between the parties with respect to the subject matter hereof.

         (c)   Waiver.  No waiver by either party of any failure or refusal to
comply with an obligation hereunder shall be deemed a waiver of any other or
subsequent failure or refusal to so comply.

         (d)   Successors and Assigns.  The stipulations in this Agreement

the respective parties.

                                       24
<PAGE>   28
thereby, and each term and provision of this Agreement shall be valid and
enforceable to the fullest extent permitted by law.

         (f)   Section Headings.  The headings of the various sections and
subsections of this Agreement have been inserted only for the purposes of
convenience and are not part of this Agreement and shall not be deemed in any
manner to modify, explain, expand or restrict any of the provisions of this
Agreement.

         (g)   Single Trust.  The Trust will be a single trust within the
meaning of Section 414(1) of the Internal Revenue Code of 1986, as amended,
with respect to the Sponsor and any other employer that adopts the Trust with
the consent of the Sponsor and the Trustee. All Trust assets will be available
to pay the benefits of all such employers' eligible employees and their
beneficiaries.

         (h)   Withdrawal.  The employers that adopt this Trust may withdraw
from the Trust by giving 60 days written notice of their intent to withdraw to
the Sponsor and the Trustee.

         The administrative committee of the Plan will then determine, within
sixty (60) days following the receipt of the notice, the portion of the Trust
that is attributable to the members employed by the withdrawing employer and
shall forward a copy of the determination to the Trustee. Upon receipt of the
determination, the Trustee will segregate those assets attributable to the
members employed by the withdrawing employer and will transfer those assets to
the successor Trustee or Trustees when it receives a designation of such
successor from the withdrawing employer.

         The withdrawal from the Trust will not terminate the Plan or Trust
with respect to the withdrawing employer.  Instead, the employer shall, as soon
as practical, either appoint a





                                       25
<PAGE>   29
successor Trustee or Trustees and reaffirm this Trust as a new and separate
trust intended to fund the Plan which is qualified under Section 401(a) of the
Code or establish another defined contribution plan and trust intended to
qualify under Section 401(a) of the Code.

         The determination of the administrative committee of the Plan, in its
sole discretion, of the portion of the Trust that is attributable to the
members employed by the withdrawing employer will be final and binding upon all
parties at interest; and, the Trustee's transfer of those assets to the
designated successor Trustee shall relieve the Trustee of any further
obligation, liability or duty to the withdrawing employer, the members employed
by that employer and their beneficiaries, and the successor Trustee or
Trustees.

Boston, MA  02109
                                 [NAME OF PLAN]
Dear Ms. Redden:

         In accordance with your request, this letter sets forth our opinion
with respect to the qualified status under section 401(a) of the Internal
Revenue Code of 1986 (including amendments made by the Employee Retirement
Income Security Act of 1974) (the "Code"), of the [name of plan], as amended to
the date of this letter (the "Plan").

         The material facts regarding the Plan as we understand them are as
follows.  The most recent favorable determination letter as to the Plan's
qualified status under section 401(a) of the Code was issued by the [location
of Key District] District Director of the Internal Revenue Service and was
dated [date] (copy enclosed).  The version of the Plan submitted by [name of
company] (the "Company") for the District Director's review in connection with
this determination letter did not contain amendments made effective as of
[date].  These amendments, among other matters, [brief description of
amendments].  [Subsequent amendments were made on [date] to amend the
provisions dealing with [brief description of amendments].]

         The Company has informed us that it intends to submit the Plan to the
[location of Key District] District Director of the Internal Revenue Service
and to request from him a favorable determination letter as to the Plan's
qualified status under section 401(a) of the Code.  The Company may have to
make some modifications to the Plan at the request of the Internal Revenue
Service in order to obtain this favorable determination letter, but we do not
expect any of these modifications to be material.  The Company has informed us
that it will make these modifications.

         Based on the foregoing statements of the Company and our review of the
provisions of the Plan, it is our opinion that the Internal Revenue Service
will issue a favorable determination letter as to the qualified status of the
Plan, as modified at the request of the Internal Revenue Service, under section
401(a) of the Code, subject to the customary condition that continued
qualification of the Plan, as modified, will depend on its effect in operation.

                               Sincerely,
                               [name of law firm]

                               By       [signature]

                         TELEPHONE EXCHANGE GUIDELINES

The following telephone exchange procedures are currently employed by Fidelity
Investments Institutional Operations Company, Inc. (FIIOC).

Telephone exchange hours are 8:30 a.m. (ET) to 8:00 p.m. (ET) on each business
day.  A "business day" is any day on which the New York Stock Exchange is open.

FIIOC reserves the right to change these telephone exchange procedures at its
discretion.

EXCHANGES BETWEEN MUTUAL FUNDS

         Participants may call on any business day to exchange between mutual
         funds.  If the request is received before 4:00 p.m. (ET), it will
         receive that day's trade date.  Calls received after 4:00 p.m. (ET)
         will be processed on a next day basis.

EXCHANGES FROM MUTUAL FUNDS TO SPONSOR STOCK

         Sponsor Stock exchanges are processed on monthly cycle.  Participants
         who wish to exchange out of a mutual fund into Sponsor Stock may call
         between the 1st and the 15th of the month.  No calls will be accepted
         after 4:00 p.m. (ET) on the 15th (or previous business day if the 15th
         is not a business day).

         Mutual fund shares are sold on the 15th of the month (or the previous
         business day if the 15th is not a business) and the Sponsor Stock is
         purchased within two (2) business days after the date on which the
         mutual fund shares are sold.

EXCHANGES FROM SPONSOR STOCK TO MUTUAL FUNDS

         Participants who wish to exchange out of Sponsor Stock into mutual
         funds may call between the 1st and the 15th of the month.  No calls
         will be accepted after 4:00p.m. (ET) on the 15th (or previous business
         day if the 15th is not a business day).

         The Sponsor Stock is sold on the 16th (or next business day if the
         16th is not a business day) and the subsequent purchase into mutual
         funds will take place five (5) business days later.  This allows for
         settlement of the stock trade at the custodian and the corresponding
         transfer to Fidelity.  Orders for sales of Sponsor Stock must be share
         specific.

         16th is not a business day) and the subsequent purchase into the

         corresponding transfer to Fidelity.  Orders for sales of Sponsor Stock
         must be share specific.
