          The following documents which have been filed with the Securities and
Exchange Commission (the "Commission") by APS Holding Corporation, a Delaware
corporation (the "Company"), are incorporated herein by reference and made a
part hereof:

          (a)  Annual Report on Form 10-K for the fiscal year ended January 27,
               1996;

          (b)  Quarterly Report on Form 10-Q for the quarter ended April 25,
               1996;

          (c)  Current Report on Form 8-K dated January 25, 1996;

               in the Company's Registration Statement on Form S-1 (Registration
               Statement No. 33-66412).

          All documents filed by the Company pursuant to Sections 13(a), 13(c),
14 and 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), subsequent to the effective date of this Registration Statement, prior to
the filing of a post-effective amendment to this Registration Statement
indicating that all securities offered hereby have been sold or deregistering
all securities then remaining unsold, shall be deemed to be incorporated by
reference herein and to be a part hereof from the date of filing of such
documents.  Any statement contained herein or in any document incorporated or
deemed to be incorporated by reference herein shall be deemed to be modified or
superseded for purposes of this Registration Statement to the extent that a
statement contained in any other subsequently filed document which also is or is
deemed to be incorporated by reference herein modifies or supersedes such
statement.  Any such statement so modified or superseded shall not be deemed to
constitute a part of this Registration Statement, except as so modified or
superseded.

ITEM 4.   DESCRIPTION OF SECURITIES.

          The Deferred Compensation Obligations registered hereunder (the
"Obligations") are unsecured obligations of the Registrant to pay deferred
compensation in the future in accordance with the terms of the A.P.S., Inc.
Executive 401(k) Deferral Plan (the "Plan") and the A.P.S., Inc. Executive
401(k) Deferral Plan Trust Agreement, dated as of August 14, 1996, between
A.P.S., Inc. and Texas Commerce Bank National Association, as Trustee (the
"Trust Agreement"), which are filed as Exhibits 4.3 and 4.4 to this Registration
Statement.  Such Exhibits set forth a description of the Obligations and are
incorporated herein by reference in their entirety in response to this Item 4.,
pursuant to Rule 411(b)(3) under the Securities Act of 1933.

          No participant under the Plan shall have any preferred claim to, or
any beneficial ownership interest in, any assets which are subject to the Trust
established by the Trust Agreement (the "Trust").  All such assets are subject
to the claims of the creditors of the participant's employer until they are paid
out of the Trust to the participant in accordance with the terms of the Plan. 
The Plan provides that payment of all Obligations of the Registrant's
subsidiaries under the Plan is guaranteed by the Registrant, and that any such
payment by the Registrant shall be made directly and not through the Trust.

ITEM 5.   INTERESTS OF NAMED EXPERTS AND COUNSEL.

          Not applicable.

ITEM 6.   INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          Reference is made to Section 102(b)(7) of the Delaware General
Corporation Law (the "DGCL"), which enables a corporation in its original
certificate of incorporation or an amendment thereto to eliminate or limit the
personal liability of a director for violations of the director's fiduciary
duty, except (i) for acts or for any breach of the director's duty of loyalty to
the corporation or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) pursuant to Section 174 of the DGCL (providing for liability of directors
for unlawful payment of dividends or unlawful stock purchases or redemptions) or
(iv) for any transaction from which a director derived an improper personal
benefit.  The Second Restated Certificate of Incorporation and Bylaws of the
Company contain provisions eliminating the liability of directors to the extent
permitted by Section 102(b)(7) of the DGCL.

          The Company is empowered by Section 145 of the DGCL, subject to the
procedures and limitations stated therein, to indemnify any person against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him or her in connection with any
threatened, pending or completed action, suit or proceeding in which such person
is made a party by reason of his or her being or having been a director,
officer, employee or agent of the Company.  The statute provides that
indemnification pursuant to its provisions is not exclusive of other rights of
indemnification to which a person may be entitled under any by-law, agreement,
vote of stockholders or disinterested directors, or otherwise.  Article VI of
the Bylaws of the Company provides for indemnification of each of the Company's
directors, officers and employees to the full extent permitted by the DGCL.

          An Indemnification Agreement exists among the Company, APS, Inc.,
Clayton, Dubilier & Rice, Inc. ("CD&R") and The Clayton & Dubilier Private
Equity Fund IV Limited Partnership ("Fund IV") that requires the Company and
APS, Inc. to indemnify CD&R, Fund IV, the general partner of Fund IV, and their
respective directors, officers, partners, employees, agents and controlling
persons (within the meaning of the Securities Act of 1933) and each other person
who is or becomes a director of the Company or APS, Inc. (the "Indemnitees") (i)
from and against all claims relating to certain potential liabilities and claims
that might arise under the securities laws from the operations of APS, Inc. and
its predecessors and, except in the case of gross negligence or intentional
misconduct, from providing management consulting and financial advisory services
and (ii) to the fullest extent permitted by applicable Delaware law, from acting
as directors of the Company and its subsidiaries or any breach or alleged breach
of his or her fiduciary duty as a director of the Company and its subsidiaries. 
In addition, the Company has agreed to indemnify the Indemnitees against any
suits, claims, damages or expenses which may be made against or incurred by them
under applicable securities laws in connection with offerings of securities of
the Company.  However, the Company will not be obligated to indemnify any
Indemnitee in the event that any such suit, claim, damage or expense is based
upon an untrue statement in any document, contract or agreement related to an
offering in reliance upon written information furnished by such Indemnitee
specifically for use in such document, contract and agreement.

ITEM 7.   EXEMPTION FROM REGISTRATION CLAIMED.

          Not applicable.

                                  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, as amended (the "1933 Act");

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

               (iii) To include any material information with respect to the
          plan of distribution not previously disclosed in the Registration
          Statement or any material change to such information in the
          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 by the Registrant pursuant to
Section 13 or Section 15(d) of the Exchange Act that are incorporated by
reference in the Registration Statement.

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

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

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

          Insofar as indemnification for liabilities arising under the 1933 Act
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 1933 Act and
is, therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the 1933 Act and will be governed by the final
adjudication of such issue.

                            As amended on January 17, 1990


                                      ARTICLE I

                                     STOCKHOLDERS

         Section 1.01.  ANNUAL MEETINGS.  The annual meeting of the
stockholders of the Corporation for the election of directors and for the
transaction of such other business as properly may come before such meeting
shall be held at such place, either within or without the State of Delaware, and
at 10:00 A.M. local time on the first Tuesday in May (or, if such day is a legal
holiday, then on the next succeeding business day), or at such other date and
hour, as may be fixed from time to time by resolution of the Board of Directors
and set forth in the notice or waiver of notice of the meeting.

         Section 1.02.  SPECIAL MEETINGS.  Special meetings of the stockholders
may be called at any time by the President (or, in the event of his absence or
disability, by any Vice President), or by the Board of Directors. A special
meeting shall be called by the President (or, in the event of his absence or
disability, by any Vice President), or by the Secretary, immediately upon
receipt of a written request therefor by stockholders holding in the aggregate
not less than a majority of the outstanding shares of the Corporation at the
time entitled to vote at any meeting of the stockholders. If such officers or
the Board of Directors shall fail to call such meeting within 20 days after
receipt of such request, any stockholder executing such request may call such
meeting. Such special meetings of the stockholders shall be held at such places
within or without the State of Delaware, as shall be specified in the respective
notices or waivers of notice thereof.

         Section 1.03.  NOTICE OF MEETINGS; WAIVER.  The Secretary or any 
Assistant Secretary shall cause written notice of the place, date and hour of 
each meeting of the stockholders, and in the case of a special meeting, the 
purpose or purposes for which such meeting is called, to be given personally 
or by mail, not less than ten nor more than sixty days prior to the meeting, 
to each stockholder of record entitled to vote at such meeting. If such

<PAGE>

notice is mailed, it shall be deemed to have been given to a stockholder when 
deposited in the United States mail, postage prepaid, directed to the 
stockholder at his address as it appears on the record of stockholders of the 
Corporation, or, if he shall have filed with the Secretary of the Corporation 
a written request that notices to him be mailed to some other address, then 
directed to him at such other address. Such further notice shall be given as 
may be required by law.

         No notice of any meeting of stockholders need be given to any
stockholder who submits a signed waiver of notice, whether before or after the
meeting. Neither the business to be transacted at, not the purpose of, any
regular or special meeting of the stockholders need be specified in a written
waiver of notice. The attendance of any stockholder at a meeting of stockholders
shall constitute a waiver of notice of such meeting, except when the stockholder
attends a meeting for the express purpose of objecting, at the beginning of the
meeting, to the transaction of any business on the ground that the meeting is
not lawfully called or convened.

         Section 1.04.  QUORUM.  Except as otherwise required by law or by 
the Certificate of Incorporation, the presence in person or by proxy of the 
holders of record of a majority of the shares entitled to vote at a meeting 
of stockholders shall constitute a quorum for the transaction of business at 
such meeting.

         Section 1.05.  VOTING.  If, pursuant to Section 5.05 of these By-Laws,
a record date has been fixed, every holder of record of shares entitled to vote
at a meeting of stockholders shall be entitled to one vote for each share
outstanding in his name on the books of the Corporation at the close of business
on such record date. If no record date has been fixed, then every holder of
record of shares entitled to vote at a meeting of stockholders shall be entitled
to one vote for each share of stock standing in his name on the books of the
Corporation at the close of business on the day next preceding the day on which
notice of the meeting is given, or, if notice is waived, at the close of
business on the day next preceding the day on which the meeting is held. Except
as otherwise required by law or by the Certificate of Incorporation, the vote of
a majority of the shares represented in person or by proxy at any meeting at
which a quorum is present shall


                                          2

<PAGE>

be sufficient for the transaction of any business at such meeting.

         Section 1.06.  VOTING BY BALLOT.  No vote of the stockholders need be
taken by written ballot or conducted by inspectors of election, unless otherwise
required by law. Any vote which need not be taken by ballot may be conducted in
any manner approved by the meeting.

         Section 1.07.  ADJOURNMENT.  If a quorum is not present at any meeting
of the stockholders, the stockholders present in person or by proxy shall have
the power to adjourn any such meeting from time to time until a quorum is
present. Notice of any adjourned meeting of the stockholders of the Corporation
need not be given if the place, date and hour thereof are announced at the
meeting at which the adjournment is taken, provided, however, that if the
adjournment is for more than thirty days, or if after the adjournment a new
record date for the adjourned meeting is fixed pursuant to Section 5.05 of these
By-Laws, a notice of the adjourned meeting, conforming to the requirements of
Section 1.03 hereof, shall be given to each stockholder of record entitled to
vote at such meeting. At any adjourned meeting at which a quorum is present, any
business may be transacted that might have been transacted on the original date
of the meeting.

         Section 1.08.  PROXIES.  Any stockholder entitled to vote at any
meeting of the stockholders or to express consent to or dissent from corporate
action without a meeting may, by a written instrument signed by such stockholder
or his attorney-in-fact, authorize another person or persons to vote at any such
meeting and express such consent or dissent for him by proxy. No such proxy
shall be voted or acted upon after the expiration of three years from the date
of such proxy, unless such proxy provides for a longer period. Every proxy shall
be revocable at the pleasure of the stockholder executing it, except in those
cases where applicable law provides that a proxy shall be irrevocable. A
stockholder may revoke any proxy which is not irrevocable by attending the
meeting and voting in person or by filing an instrument in writing revoking the
proxy or by filing another duly executed proxy bearing a later date with the
Secretary.

         Section 1.09. ORGANIZATION; PROCEDURE.  At every meeting of
stockholders the presiding officer shall be the President or, in the event of
his absence or


                                          3

<PAGE>

disability, a presiding officer chosen by a majority of the stockholders present
in person or by proxy. The Secretary, or in the event of his absence or
disability, the Assistant Secretary, if any, or if there be no Assistant
Secretary, in the absence of the Secretary, an appointee of the presiding
officer, shall act as Secretary of the meeting. The order of business and all
other matters of procedure at every meeting of stockholders may be determined by
such presiding officer.

         Section 1.10.  CONSENT OF STOCKHOLDERS IN LIEU OF MEETING.  To the
fullest extent permitted by law, whenever the vote of stockholders at a meeting
thereof is required or permitted to be taken for or in connection with any
corporate action, such action may be taken without a meeting, without prior
notice and without a vote of stockholders, if a consent or consents in writing,
setting forth the action so taken, shall be signed by the holders of outstanding
stock having not less than the minimum number of votes that would be necessary
to authorize or take such action at a meeting at which all shares entitled to
vote thereon were present and voted and shall be delivered to the Corporation by
delivery to its registered office in the State of Delaware, its principal place
of business, or an officer or agent of the Corporation having custody of the
book in which proceedings of meetings of stockholders are recorded.  Delivery
made to the Corporation's registered office shall be by hand or by certified or
registered mail, return receipt requested.

         Every written consent shall bear the date of signature of each
stockholder or member who signs the consent and no written consent shall be
effective to take the corporate action referred to therein unless, within sixty
days of the earliest dated consent delivered in the manner required by law to
the Corporation, written consents signed by a sufficient number of holders or
members to take action are delivered to the Corporation by delivery to its
registered office in the State of Delaware, its principal place of business, or
an officer or agent of the Corporation having custody of the book in which
proceedings of meetings of stockholders are recorded.  Delivery made to the
Corporation's registered office shall be by hand or by certified or registered
mail, return receipt requested.

                                  BOARD OF DIRECTORS

         Section 2.01.  GENERAL POWERS.  Except as may otherwise be provided by
law, by the Certificate of Incorporation or by these By-Laws, the property,
affairs and business of the Corporation shall be managed by or under the
direction of the Board of Directors and the Board of Directors may exercise all
the powers of the Corporation.

         Section 2.02.  NUMBER AND TERM OF OFFICE.  The number of Directors
constituting the entire Board of Directors shall be three, which number may be
modified from time to time by resolution of the Board of Directors, but in no
event shall the number of Directors be less than one.  Each Director (whenever
elected) shall hold office until his successor has been duly elected and
qualified, or until his earlier death, resignation or removal.

         Section 2.03.  ELECTION OF DIRECTORS.  Except as otherwise provided in
Sections 2.12 and 2.13 of these By-Laws, the Directors shall be elected at each
annual meeting of the stockholders.  If the annual meeting for the election of
Directors is not held on the date designated therefor, the Directors shall cause
the meeting to be held as soon thereafter as convenient.  At each meeting of the
stockholders for the election of Directors, provided a quorum is present, the
Directors shall be elected by a plurality of the votes validly cast in such
election.

         Section 2.04.  ANNUAL AND REGULAR MEETINGS.  The annual meeting of 
the Board of Directors for the purpose of electing officers and for the 
transaction of such other business as may come before the meeting shall be 
held as soon as possible following adjournment of the annual meeting of the 
stockholders at the place of such annual meeting of the stockholders.  Notice 
of such annual meeting of the Board of Directors need not be given.  The 
Board of Directors from time to time may by resolution provide for the 
holding of regular meetings and fix the place (which may be within or without 
the State of Delaware) and the date and hour of such meetings.  Notice of 
regular meetings need not be given, provided, however, that if the Board of 
Directors shall fix or change the time or place of any regular meeting, 
notice of such action shall be mailed promptly, or sent by telegram,

                                          5

<PAGE>

radio or cable, to each Director who shall not have been present at the meeting
at which such action was taken, addressed to him at his usual place of business,
or shall be delivered to him personally.  Notice of such action need not be
given to any Director who attends the first regular meeting after such action is
taken without protesting the lack of notice to him, prior to or at the
commencement of such meeting, or to any Director who submits a signed waiver of
notice, whether before or after such meeting.

         Section 2.05.  SPECIAL MEETINGS; NOTICE.  Special meetings of the 
Board of Directors shall be held whenever called by the President or, in the 
event of his absence or disability, by any Vice President, at such place 
(within or without the State of Delaware), date and hour as may be specified 
in the respective notices or waivers of notice of such meetings.  Special 
meetings of the Board of Directors may be called on 24 hours' notice, if 
notice is given to each Director personally or by telephone or telegram, or 
on five days' notice, if notice is mailed to each Director, addressed to him 
at his usual place of business.  Notice of any special meeting need not be 
given to any Director who attends such meeting without protesting the lack of 
notice to him, prior to or at the commencement of such meeting, or to any 
Director who submits a signed waiver of notice, whether before or after such 
meeting, and any business may be transacted thereat.

         Section 2.06.  QUORUM; VOTING.  At all meetings of the Board of 
Directors, the presence of a majority of the total authorized number of 
Directors shall constitute a quorum for the transaction of business.  Except 
as otherwise required by law, the vote of a majority of the Directors present 
at any meeting at which a quorum is present shall be the act of the Board of 
Directors.

         Section 2.07.  ADJOURNMENT.  A majority of the Directors present,
whether or not a quorum is present, may adjourn any meeting of the Board of
Directors to another time or place.  No notice need be given of any adjourned
meeting unless the time and place of the adjourned meeting are not announced at
the time of adjournment, in which case notice conforming to the requirements of
Section 2.05 shall be given to each Director.

         Section 2.08  ACTION WITHOUT A MEETING.  Any action required or
permitted to be taken at any meeting of


                                          6

<PAGE>

the Board of Directors may be taken without a meeting if all members of the 
Board of Directors consent thereto in writing, and such writing or writings 
are filed with the minutes of proceedings of the Board of Directors.

         Section 2.09.  REGULATIONS; MANNER OF ACTING.  To the extent 
consistent with applicable law, the Certificate of Incorporation and these 
By-Laws, the Board of Directors may adopt such rules and regulations for the 
conduct of meetings of the Board of Directors and for the management of the 
property, affairs and business of the Corporation as the Board of Directors 
may deem appropriate.  The Directors shall act only as a Board, and the 
individual Directors shall have no power as such.

         Section 2.10.  ACTION BY TELEPHONIC COMMUNICATIONS.  Members of the
Board of Directors may participate in a meeting of the Board of Directors by
means of conference telephone or similar communications equipment by means of
which all persons participating in the meeting can hear each other, and
participation in a meeting pursuant to this provision shall constitute presence
in person at such meeting.

         Section 2.11.  RESIGNATIONS.  Any Director may resign at any time by
delivering a written notice of resignation, signed by such Director, to the
President or the Secretary.  Unless otherwise specified therein, such
resignation shall take effect upon delivery.

         Section 2.12.  REMOVAL OF DIRECTORS.  Any Director may be removed at
any time, either for or without cause, upon the affirmative vote of the holders
of a majority of the outstanding shares of stock of the Corporation entitled to
vote for the election of such Director, cast at a special meeting of
stockholders called for the purpose.  Any vacancy in the Board of Directors
caused by any such removal may be filled at such meeting by the stockholders
entitled to vote for the election of the Director so removed.  If such
stockholders do not fill such vacancy at such meeting (or in the written
instrument effecting such removal, if such removal was effected by consent
without a meeting), such vacancy may be filled in the manner provided in Section

    the designations and any of the preferences or rights of such shares

    from any person or entity, whether by asset purchase, stock purchase,
    merger or other business combination, when such transaction would require a
    waiver under, consent or modification to the Loan Agreement dated September
    30, 1993, with the several lenders and Chemical Bank, as Agent.

present at any meeting at which a quorum is present shall be the act of such
Committee.  Any action required or permitted to be taken at any meeting of any
such Committee may be taken without a meeting, if all members of such Committee
shall consent to such action in writing and such writing or writings are filed
with the minutes of the proceedings of the Committee.  The members of any such
Committee shall act only as a Committee, and the individual members of such
Committee shall have no power as such.

         Section 3.05.  ACTION BY TELEPHONIC COMMUNICATIONS.  Members of any
Committee designated by the Board of Directors may participate in a meeting of
such Committee by means of conference telephone or similar communications
equipment by means of which all persons participating in the meeting can hear
each other, and participation in a meeting pursuant to this provision shall
constitute presence in person at such meeting.

disqualification of a member of any Committee, the member or members thereof
present at any meeting and not disqualified from voting, whether or not he or

          Section 5.01.  CERTIFICATES OF STOCK, UNCERTIFICATED SHARES. The
shares of the Corporation shall be represented by certificates, provided that
the Board of Directors may provide by resolution or resolutions that some or all
of any or all classes or series of the stock of the Corporation shall be
uncertificated shares. Any such resolution shall not apply to shares represented
by a certificate until each certificate is surrendered to the Corporation.
Notwithstanding the adoption of such a resolution by the Board of Directors,
every holder of stock in the Corporation represented by certificates and

                                          16

<PAGE>

upon request every holder of uncertificated shares shall be entitled to have a
certificate signed by, or in the name of the Corporation, by the President or a
Vice President, and by the Treasurer or an Assistant Treasurer, or the Secretary
or an Assistant Secretary, representing the number of shares registered in
certificate form. Such certificate shall be in such form as the Board of
Directors may determine, to the extent consistent with applicable law, the
Certificate of Incorporation and these By-Laws.

          Section 5.02.  SIGNATURES; FACSIMILE. All of such signatures on the
certificate may be a facsimile, engraved or printed, to the extent permitted by
law. In case any officer, transfer agent or registrar who has signed, or whose

such officer, transfer agent or registrar before such certificate is issued, it
may be issued by the Corporation with the same effect as if he were such
officer, transfer agent or registrar at the date of issue.

          Section 5.03. LOST, STOLEN OR DESTROYED CERTIFICATES. The Board of
Directors may direct that a new certificate be issued in place of any
certificate theretofore issued by the Corporation alleged to have been lost,
stolen or destroyed, upon delivery to the Board of Directors of an affidavit of
the owner or owners of such certificate, setting forth such allegation. The
Board of Directors may require the owner of such lost, stolen or destroyed
certificate, or his legal representative, to give the Corporation a bond
sufficient to indemnify it against any claim that may be made against it on
account of the alleged loss, theft or destruction of any such certificate or the
issuance of any such new certificate.

          Section 5.04.  TRANSFER OF STOCK. Upon surrender to the Corporation or
the transfer agent of the Corporation of a certificate for shares, duly endorsed
or accompanied by appropriate evidence of succession, assignment or authority to
transfer, the Corporation shall issue a new certificate to the person entitled
thereto, cancel the old certificate and record the transaction upon its books.
Within a reasonable time after the transfer of uncertificated stock, the
Corporation shall send to the registered owner thereof a written notice
containing the information required to be set forth or stated on certificates
pursuant to Sections 151, 156, 202(a) or 218(a) of

                                          17

<PAGE>

the General Corporation Law of the State of Delaware. Subject to the provisions
of the Certificate of Incorporation and these By-Laws, the Board of Directors
may prescribe such additional rules and regulations as it may deem appropriate
relating to the issue, transfer and registration of shares of the Corporation.

          Section 5.05.  RECORD DATE. In order to determine the stockholders
entitled to notice of or to vote at any meeting of stockholders or any
adjournment thereof, the Board of Directors may fix, in advance, a record date,
which record date shall not precede the date on which the resolution fixing the
record date is adopted by the Board of Directors, and which shall not be more
than sixty nor less than ten days before the date of such meeting. A
determination of stockholders of record entitled to notice of or to vote at a
meeting of stockholders shall apply to any adjournment of the meeting, provided,
however, that the Board of Directors may fix a new record date for the adjourned
meeting.

          In order that the Corporation may determine the stockholders entitled
to consent to corporate action in writing without a meeting, the Board of
Directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board of
Directors, and which date shall not be more than ten days after the date upon
which the resolution fixing the record date is adopted by the Board of
Directors. If no record date has been fixed by the Board of Directors, the
record date for determining stockholders entitled to consent to corporate action
in writing without a meeting, when no prior action by the board of directors is
required by law, shall be the first date on which a signed written consent
setting forth the action taken or proposed to be taken is delivered to the
Corporation by delivery to its registered office in the State of Delaware, its
principal place of business, or an officer or agent of the Corporation having
custody of the book in which proceedings of meetings of stockholders are
recorded. Delivery made to the Corporation's registered office shall be by hand
or by certified or registered mail, return receipt requested. If no record date
has been fixed by the Board of Directors and prior action by the Board of
Directors is required by law, the record date for determining stockholders
entitled to consent to corporate action in writing without a meeting shall be at

                                          18

<PAGE>

the close of business on the day on which the Board of Directors adopts the
resolution taking such prior action.

          In order that the Corporation may determine the stockholders entitled
to receive payment of any dividend or other distribution or allotment of any
rights of the stockholders entitled to exercise any rights in respect of any
change, conversion or exchange of stock, or for the purpose of any other lawful
action, the Board of Directors may fix a record date, which record date shall
not precede the date upon which the resolution fixing the record date is
adopted, and which record date shall be not more than sixty days prior to such
action. If no record date is fixed, the record date for determining stockholders
for any such purpose shall be at the close of business on the day on which the
Board of Directors adopts the resolution relating thereto.

          Section 5.06. REGISTERED STOCKHOLDERS. Prior to due surrender of a
certificate for registration of transfer, the Corporation may treat the
registered owner as the person exclusively entitled to receive dividends and
other distributions, to vote, to receive notice and otherwise to exercise all
the rights and powers of the owner of the shares represented by such
certificate, and the Corporation shall not be bound to recognize any equitable
or legal claim to or interest in such shares on the part of any other person,
whether or not the Corporation shall have notice of such claim or interests.
Whenever any transfer of shares shall be made for collateral security, and not
absolutely, it shall be so expressed in the entry of the transfer if, when the
certificates are presented to the Corporation for transfer or uncertificated
shares are requested to be transferred, both the transferor and transferee
request the Corporation to do so.

          Section 5.07.  TRANSFER AGENT AND REGISTRAR. The Board of Directors
may appoint one or more transfer agents and one or more registrars, and may
require all certificates representing shares to bear the signature of any such
transfer agents or registrars.

                                   INDEMNIFICATION

          Section 6.01. NATURE OF INDEMNITY. The Corporation shall indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that he is or
was or has agreed to become a director or officer of the Corporation, or is or
was serving or has agreed to serve at the request of the Corporation as a
director or officer, of another corporation, partnership, joint venture, trust
or other enterprise, or by reason of any action alleged to have been taken or
omitted in such capacity, and may indemnify any person who was or is a party or
is threatened to be made a party to such an action, suit or proceeding by reason
of the fact that he is or was or has agreed to become an employee or agent of
the Corporation, or is or was serving or has agreed to serve at the request of
the Corporation as an employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him or on his behalf in connection with such action, suit or
proceeding and any appeal therefrom, if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding had no
reasonable cause to believe his conduct was unlawful; except that in the case of
an action or suit by or in the right of the Corporation to procure a judgment in
its favor (1) such indemnification shall be limited to expenses (including
attorneys' fees) actually and reasonably incurred by such person in the defense
or settlement of such action or suit, and (2) no indemnification shall be made
in respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the Corporation unless and only to the extent that the
Delaware Court of Chancery or the court in which such action or suit was brought
shall determine upon application that, despite the adjudication of liability but
in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such expenses which the Delaware Court of
Chancery or such other court shall deem proper.

                                          20



<PAGE>





          The termination of any action, suit or proceeding by judgment, order
settlement, conviction, or upon a plea of NOLO CONTENDERE or its equivalent,
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner which he reasonably believed to be in or not opposed to
the best interests of the Corporation, and, with respect to any criminal action
or proceeding, had reasonable cause to believe that his conduct was unlawful.

          Section 6.02.  SUCCESSFUL DEFENSE. To the extent that a director, 
officer, employee or agent of the Corporation has been successful on the 
merits or otherwise in defense of any action, suit or proceeding referred to 
in Section 6.01 hereof or in defense of any claim, issue or matter therein, 
he shall be indemnified against expenses (including attorneys' fees) actually 
and reasonably incurred by him in connection therewith.

          Section 6.03.  DETERMINATION THAT INDEMNIFICATION IS PROPER.  Any 
indemnification of a director or officer of the Corporation under Section 
6.01 hereof (unless ordered by a court) shall be made by the Corporation 
unless a determination is made that indemnification of the director or 
officer is not proper in the circumstances because he has not met the 
applicable standard of conduct set forth in Section 6.01 hereof.  Any 
indemnification of an employee or agent of the Corporation under Section 6.01 
hereof (unless ordered by a court) may be made by the Corporation upon a 
determination that indemnification of the employee or agent is proper in the 
circumstances because he has met the applicable standard of conduct set forth 
in Section 6.01 hereof.  Any such determination shall be made (1) by the 
Board of Directors by a majority vote of a quorum consisting of directors who 
were not parties to such action, suit or proceeding, or (2) if such a quorum 
is not obtainable, or, even if obtainable a quorum of disinterested directors 
so directs, by independent legal counsel in a written opinion, or (3) by the 
stockholders.

          Section 6.4.  ADVANCE PAYMENT OF EXPENSES.  Expenses (including 
attorneys' fees) incurred by a director or officer in defending any civil, 
criminal, administrative or investigative action, suit or proceeding shall be 
paid by the Corporation in advance of the final disposition of such action, 
suit or proceeding upon receipt of an undertaking by or on behalf of the 
director or officer to repay such amount if it shall ultimately be determined 
that he is not entitled to be indemnified by the Corporation as authorized in 
this Article. Such expenses (including attorneys' fees) incurred by other 
employees and agents may be so paid upon such terms and conditions, if any, 
as the Board of Directors may authorize the Corporation's counsel to 
represent such director, officer, employee or agent in any action, suit or 
proceeding, whether or not the Corporation is a party to such action, suit or 
proceeding.

          Section 6.05.  PROCEDURE FOR INDEMNIFICATION OF DIRECTORS AND 
OFFICERS.  Any indemnification of a director or officer of the Corporation 
under Sections 6.01 and 6.02, or advance of costs, charges and expenses to a 
director or officer under Section 6.04 of this Article, shall be made 
promptly, and in any event within 30 days, upon the written request of the 
director or officer. If a determination by the Corporation that the director 
or officer is entitled to indemnification pursuant to this Article is 
required, and the Corporation fails to respond within sixty days to a written 
request for indemnity, the Corporation shall be deemed to have approved such 
request.  If the Corporation denies a written request for indemnity or 
advancement of expenses, in whole or in part, or if payment in full pursuant 
to such request is not made within 30 days, the right to indemnification or 
advances as granted by this Article shall be enforceable by the director or 
officer in any court of competent jurisdiction.  Such person's costs and 
expenses incurred in connection with successfully establishing his right to 
indemnification, in whole or in part, in any such action shall also be 
indemnified by the Corporation.  It shall be a defense to any such action 
(other than an action brought to enforce a claim for the advance of costs, 
charges and expenses under Section 6.04 of this Article where the required 
undertaking, if any, has been received by the Corporation) that the claimant 
has not met the standard of conduct set forth in Section 6.01 of this 
Article, but the burden of proving such defense shall be on the 
Corporation.  Neither the failure of the Corporation (including its Board of 
Directors, its independent legal counsel, and its stockholders) to have made 
a determination prior to the commencement of such action that indemnification 
of the claimant is proper in the circumstances because he has met the 
applicable standard of conduct set forth in Section 6.01 of this Article, nor 
the fact that there has been an actual determination by the Corporation 
(including its Board of Directors, its independent legal counsel, and

                                          22

<PAGE>

its stockholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that the
claimant has not met the applicable standard of conduct.

         Section 6.06.  SURVIVAL; PRESERVATION OF OTHER RIGHTS.  The foregoing
indemnification provisions shall be deemed to be a contract between the
Corporation and each director, officer, employee and agent who serves in any
such capacity at any time while these provisions as well as the relevant
provisions of the Delaware Corporation Law are in effect and any repeal or
modification thereof shall not affect any right or obligation then existing with
respect to any state of facts then or previously existing or any action, suit or
proceeding previously or thereafter brought or threatened based in whole or in
part upon any such state of facts.  Such a "contract right" may not be modified
retroactively without the consent of such director, officer, employee or agent.

         The indemnification provided by this Article VI shall not be deemed
exclusive of any other rights to which those indemnified may be entitled under
any by-law, agreement, vote of stockholders or disinterested directors or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding such office, and shall continue as to a person
who has ceased to be a director, officer, employee or agent and shall inure to
the benefit of the heirs, executors and administrators of such a person.

         Section 6.07.  INSURANCE.  The Corporation shall purchase and maintain
insurance on behalf of any person who is or was or has agreed to become a
director or officer of the Corporation , or is or was serving at the request of
the Corporation as a director or officer of another corporation, partnership,
joint venture, trust or other enterprise against any liability asserted against
him and incurred by him or on his behalf in any such capacity, or arising out of
his status as such, whether or not the Corporation would have the power to
indemnify him against such liability under the provisions of this Article,
PROVIDED that such insurance is available on acceptable terms, which
determination shall be made by a vote of a majority of the entire Board of
Directors.

         Section 6.08.  SEVERABILITY.  If this Article or any portion hereof
shall be invalidated on any ground


                                          23

<PAGE>

by any court of competent jurisdiction, then the Corporation shall nevertheless
indemnify each director or officer and may indemnify each employee or agent of
the Corporation as to costs, charges and expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement with respect to any action, suit
or proceeding, whether civil, criminal, administrative or investigative,
including an action by or in the right of the Corporation, to the fullest extent
permitted by any applicable portion of this Article that shall not have been
invalidated and to the fullest extent permitted by applicable law.

places of business at such other locations within or without the State of

business of the Corporation may require.

                                     ARTICLE VIII

                                  GENERAL PROVISIONS

         Section 8.01.  DIVIDENDS.  Subject to any applicable provisions of law
and the Certificate of Incorporation, dividends upon the shares of the

         A member of the Board of Directors, or a member of any Committee
designated by the Board of Directors shall be fully protected in relying in good
faith upon the records of the Corporation and upon such information, opinions,
reports or statements presented to the Corporation by any of its officers or
employees, or Committees of the Board of Directors, or by any other person as to


                                          24

<PAGE>

matters the Director reasonably believes are within such other person's
professional or expert competence and who has been selected with reasonable care
by or on behalf of the Corporation, as to the value and amount of the assets,
liabilities and/or net profits of the Corporation, or any other facts pertinent
to the existence and amount of surplus or other funds from which dividends might
properly be declared and paid.

         Section 8.02.  RESERVES.  There may be set aside out of any funds of
the Corporation available for dividends such sum or sums as the Board of
Directors from time to time, in its absolute discretion, thinks proper as a
reserve or reserves to meet contingencies, or for equalizing dividends, or for
repairing or maintaining any property of the Corporation or for such other
purpose as the Board of Directors shall think conducive to the interest of the
Corporation, and the Board of Directors may similarly modify or abolish any such
reserve.

         Section 8.03.  EXECUTION OF INSTRUMENTS.  The President, any Vice
President, the Secretary or the Treasurer may enter into any contract or execute
and deliver any instrument in the name and on behalf of the Corporation.  The
Board of Directors or the President may authorize any other officer or agent to
enter into any contract or execute and deliver any instrument in the name and on
behalf of the Corporation.  Any such authorization may be general or limited to
specific contracts or instruments.

         Section 8.04.  CORPORATE INDEBTEDNESS.  No loan shall be contracted on
behalf of the Corporation, and no evidence of indebtedness shall be issued in
its name, unless authorized by the Board of Directors or the President.  Such
authorization may be general or confined to specific instances.  Loans so
authorized may be effected at any time for the Corporation from any bank, trust
company or other institution, or from any firm, corporation or individual.  All
bonds, debentures, notes and other obligations or evidences of indebtedness of
the Corporation issued for such loans shall be made, executed and delivered as
the Board of Directors or the President shall authorize.  When so authorized by
the Board of Directors or the President, any part of or all the properties,
including contract rights, assets, business or good will of the Corporation,
whether then owned or thereafter acquired, may be mortgaged, pledged,
hypothecated or


                                          25

<PAGE>

conveyed or assigned in trust as security for the payment of such bonds,

Corporation, and of the interest thereon, by instruments executed and delivered
in the name of the Corporation.

         Section 8.05.  DEPOSITS.  Any funds of the Corporation may be
deposited from time to time in such banks, trust companies or other depositaries
as may be determined by the Board of Directors or the President, or by such
officers or agents as may be authorized by the Board of Directors or the
President to make such determination.

         Section 8.06.  CHECKS.  All checks or demands for money and notes of
the Corporation shall be signed by such officer or officers or such agent or
agents of the Corporation, and in such manner, as the Board of Directors or the
President form time to time may determine.

         Section 8.07.  SALE, TRANSFER, ETC. OF SECURITIES.  To the extent
authorized by the Board of Directors or by the President, any Vice President,
the Secretary or the Treasurer or any other officers designated by the Board of
Directors or the President may sell, transfer, endorse, and assign any shares of
stock, bonds or other securities owned by or held in the name of the

such sale, transfer, endorsement or assignment.

by resolution of the Board of Directors, the President or any Vice President 
shall have full power an authority on behalf of the Corporation to attend any 
meeting of stockholders of any corporation in which the Corporation may hold 
stock, and to act, vote (or execute proxies to vote) and exercise in person 
or by proxy all other rights, powers and privileges incident to the ownership 
of such stock. Such officers acting on behalf of the Corporation shall have 
full power and authority to execute any instrument expressing consent to or 
dissent from any action of any such corporation without a meeting.  The Board 
of Directors may by resolution from time to time confer such power and 
authority upon any other person or persons.

                                          26

reproduced; or may be used in any other lawful manner.

         Section 8.10.  BOOKS AND RECORDS; INSPECTION.  Except to the extent

          (b)  Notwithstanding any provision herein to the contrary, an Eligible

                                      III.

                         ACCOUNT CREDITS AND ALLOCATIONS

     3.1  MEMBER DEFERRALS.

          (a)  As a condition to Plan participation, a Member meeting the
eligibility requirements of Section 2.1 shall elect to defer from his Pay an
amount equal to 6% of his "Compensation" while a "Participant," as defined under
the Partnership Plan, for a Plan Year without regard to the maximum dollar
limitation under Section 401(a)(17) of the Code and without regard to the
exclusion for deferred compensation respecting Member Deferrals under the Plan,
reduced by his "Salary Reduction Contributions" made to the Partnership Plan for
such "Plan Year;" and

          (b)   A Member meeting the eligibility requirements of Section 2.1 may
elect to defer from his Pay an integral percentage of from 1% to 25% of his base
annual salary for a Plan Year; and/or

          (c)  A Member meeting the eligibility requirements of Section 2.1 may
elect to defer from his Pay an integral percentage of from 1% to 25% of his
annual incentive bonus for the fiscal year of the Company commencing within a
Plan Year.

          (d)  Notwithstanding the foregoing, with respect to an Eligible
Individual who first becomes a Member on other than the first day of a Plan
Year, any such Member Deferrals pursuant to Section 3.1(a) and/or 3.1(b) shall
apply only for the portion of such Plan Year commencing with the date he first
becomes a Member and ending on the last day of such Plan Year.  Notwithstanding
the foregoing, with respect to the Plan's initial election, any such Member
Deferrals pursuant to 


                                     -5-

<PAGE>

Section 3.1(c) shall apply to the annual incentive bonus for the fiscal year 
of the Company commencing in 1996.

          (e)  Pay for a Plan Year not so deferred by such election pursuant to
this Section shall be received by such Member in cash.  A Member's election to
defer an amount of his Pay pursuant to this Section shall be made by effecting,
in the form prescribed by the Plan Administrator, a Member Deferral election
pursuant to which the Member authorizes the Company to reduce his Pay in the
elected amount and the Company, in consideration thereof, agrees to credit an
equal amount to the Plan.  The reduction in a Member's Pay pursuant to Section
3.1(a) and/or 3.1(b) shall be effected by equal Pay reductions each pay period
during the applicable portion of the Plan Year as determined by the Plan
Administrator following the effective date of such election.  The reduction in a
Member's Pay pursuant to Section 3.1(c) shall be effected by a Pay reduction at
the time such annual bonus is paid.  Such Pay reductions shall be within the
Plan Year to which the Member Deferral election relates, except that Pay
reductions attributable to elections pursuant to Section 3.1(c) shall be made
within the next following Plan Year.  Member Deferrals made by a Member shall be
credited to his Member Deferral Account as of the date deferred.

          (f)  Notwithstanding the foregoing, a Member Deferral election of a
Member pursuant to Section 3.1(a) and/or 3.1(b) for a Plan Year shall be
automatically suspended during such Member's unpaid leave of absence and upon
termination of such Member's employment with the Company and its Affiliates.  A
Member Deferral election of a Member pursuant to Section 3.1(a) and/or 3.1(b)
may, with the consent of the Plan Administrator, be suspended for the remainder
of the Plan Year in which such Member has an unpaid leave of absence.  A Member
Deferral election of a Member pursuant to Section 3.1(c) may, with the consent
of the Plan Administrator, be suspended for the Plan Year in which such Member
has an unpaid leave of absence or terminates employment with the Company and its
Affiliates.  Any such Member may again become entitled to make Member Deferrals
hereunder for any subsequent Plan Year following return to full-time employment.

          (g)  A Member Deferral election pursuant to Section 3.1 shall become
effective as of the Entry Date which is on or after the date the election is
effected by the Member; provided, that for a Member's initial year of
eligibility for the Plan, Member Deferrals pursuant to Section 3.1(c) shall
apply for the full annual incentive bonus payable for the fiscal year of the
Company commencing within the Plan Year in which such Member's initial year of
eligibility occurs.  A Member Deferral election shall remain in force and effect
for the entire (or partial, if applicable) Plan Year to which such election
relates.  A Member Deferral election pursuant to Section 3.1 (other than with
respect to the timing of distributions prior to termination of employment with
the Company and its Affiliates) shall remain in force and effect for each
subsequent Plan Year (following the Member's initial year of participation in
the Plan) for which he satisfies the eligibility requirements set forth in
Section 2.1, unless and until such election is changed or revoked by such Member
prior to the Entry Date of the subsequent Plan Year to which such change or
revocation relates. 

          (h)  A Member Deferral election shall indicate the applicable time and
form of payment, as provided in Sections 7.2 and 7.3, for the Pay deferred
thereunder for such Plan Year and 


                                     -6-

<PAGE>

the net income (or net loss) equivalents allocated with respect thereto.  
Such time and form of payment election for such Plan Year shall also apply to 
any Company Deferrals for such Plan Year and the net income (or net loss) 
equivalents allocated with respect thereto.  Each Member's Accounts shall be 
divided into subaccounts to reflect such Member's various elections 
respecting time and form of payment.

          (i)  A Member who has made a Member Deferral election pursuant to
Section 3.1 may change his election, as of the Entry Date of any subsequent Plan
Year, by effecting a new Member Deferral election prior to such Entry Date and
within the time period prescribed by the Plan Administrator.

          (j)  A Member who has made a Member Deferral election pursuant to
Section 3.1 may cancel his election, as of the Entry Date of any subsequent Plan
Year, by effecting the same in the form prescribed by the Plan Administrator
prior to such Entry Date and within the time period prescribed by the Plan
Administrator.  A Member who so cancels his Member Deferral election may again
make a new such Member Deferral election for a subsequent Plan Year, if he
satisfies the eligibility requirements set forth in Section 2.1, by effecting a
new such Member Deferral election prior to the Entry Date of such Plan Year and
within the time period prescribed by the Plan Administrator.

          (k)  In the event that the Plan Administrator, upon written petition
of a Member, determines in its sole discretion that such Member has suffered an
Unforeseeable Financial Emergency, the Member Deferral election of such Member
then in effect, if any, shall be terminated as soon as administratively
practicable after such determination.  A Member whose Member Deferral election
has been so terminated may again make a new Member Deferral election for a
subsequent Plan Year that begins at least twelve months after the effective date
of such termination, if he satisfies the eligibility requirements set forth in
Section 2.1, by effecting a new Member Deferral election for such Plan Year and
within the time period prescribed by the Plan Administrator.

     3.2  COMPANY DEFERRALS.

          (a)  For each calendar month, the Company shall make Company Deferrals
on a Member's behalf in an amount which equals 50% of the Member Deferrals made
pursuant to Section 3.1(a) by such Member during such month.

          (b)  Company Deferrals made on a Member's behalf pursuant to Section
3.2(a) shall be credited to his Company Deferral Account in accordance with the
procedures established from time to time by the Plan Administrator.

          (c)  As of any date selected by the Company, the Company may make
Company Deferrals on a Member's behalf in such amount, if any, as the Company
shall determine in its sole discretion.  Such Company Deferrals may be made on
behalf of some Members but not others, and such Company Deferrals may vary among
individual Members in amount and/or with respect to the Account to which they
are credited.

     3.3  ALLOCATION OF NET INCOME OR NET LOSS EQUIVALENTS.

          (a)  As of each Valuation Date, the Plan Administrator shall determine
the net income (or net loss) equivalents of each Fund for the period elapsed
since the next preceding Valuation Date.  The net income (or net loss)
equivalent of each Fund since the next preceding Valuation Date shall be
ascertained by the Plan Administrator based upon changes in net asset value in
such manner as it deems appropriate, which may include expenses of operating the
Fund.

          (b)  For purposes of allocations of net income (or net loss)
equivalents, each Member's Accounts shall be divided into subaccounts to reflect
such Member's deemed investment in a particular Fund or Funds pursuant to
Article IV.  As of each Valuation Date, the net income (or net loss) equivalent
of each Fund, separately and respectively, shall be allocated among the
corresponding subaccounts of the Members who were deemed to have had such
corresponding subaccounts invested in such Funds since the next preceding
Valuation Date.

          (c)  So long as there is any balance in any Account, such Account
shall continue to receive allocations pursuant to this Section.

                                       IV.

                           DEEMED INVESTMENT OF FUNDS

     Each Member shall designate, in accordance with the procedures established
from time to time by the Plan Administrator, the manner in which the amounts
allocated to his Accounts shall be deemed to be invested from among the Funds
made available from time to time for such purpose by the Plan Administrator, and
such Funds shall include the Stock Fund.  Such Member may designate one of such
Funds for the deemed investment of all the amounts allocated to his Accounts or
he may split the deemed investment of the amounts allocated to his Accounts
between such Funds in 5% increments.  Notwithstanding the foregoing, a Member
may not initially designate the Stock Fund for greater than 50% of the amounts
to be allocated to his Accounts.  If a Member fails to make a proper
designation, then his Accounts shall be deemed to be invested in the Fund or
Funds designated by the Plan Administrator from time to time in a uniform and
nondiscriminatory manner.  Any such initial designation by an Insider affecting
the Stock Fund shall be approved in advance of the effective date of such
initial designation by either the Parent Board or the Committee.

     A Member may change his deemed investment designation for future amounts to
be allocated to his Accounts.  Any such change shall be made as of the first day
of any calendar quarter in accordance with the procedures established by the
Plan Administrator, and the frequency of such changes may be limited by the Plan
Administrator.  Any such change in designation by an Insider affecting the Stock
Fund shall be approved in advance of the effective date of such change of
designation by either the Parent Board or the Committee.  Notwithstanding the
foregoing, a Member may not designate the Stock Fund for greater than 50% of the
future amounts to be allocated to his Accounts.


                                     -8-


<PAGE>

     A Member may elect to convert his deemed investment designation with
respect to the amounts already allocated to his Accounts.  Any such conversion
shall be made as of the first day of any calendar quarter in accordance with the
procedures established by the Plan Administrator, and the frequency of such
conversions may be limited by the Plan Administrator.  No election of a
conversion designation by an Insider which has the effect of increasing the
total amount allocated to the Stock Fund may be made on a date which is less
than six months following (i) the date of any prior election of a conversion
designation by such Insider which had the effect of decreasing the total amount
allocated to the Stock Fund or (ii) the date of any election by such Insider
with respect to any other plan of the Parent Company or any subsidiary thereof
which had the effect (directly or indirectly) of making a disposition on behalf
of such Insider of Common Stock.  No election of a conversion designation by an
Insider which has the effect of decreasing the total amount allocated to the
Stock Fund may be made on a date which is less than six months following (i) the
date of any prior election of a conversion designation by such Insider which had
the effect of increasing the total amount allocated to the Stock Fund or (ii)
the date of any election by such Insider with respect to any other plan of the
Parent Company or any subsidiary thereof which had the effect (directly or
indirectly) of making an acquisition on behalf of the Insider of Common Stock.

     The restrictions contained herein regarding investment designations,
changes, and/or conversions by Insiders respecting the Stock Fund are intended
to comply with, and enable Insiders to rely upon, the exemption provided by Rule
16b-3 under the Securities Exchange Act of 1934.  Any future amendment to Rule
16b-3 or any successor rule promulgated by the Securities and Exchange
Commission affecting the investment by Insiders in the Stock Fund shall be
incorporated by reference herein and be deemed to be an amendment to the Plan in
order that Insiders shall continue to be entitled to rely upon the exemption
provided by such rule without any interruption.  Notwithstanding the foregoing,
the Plan Administrator may alter the designation, change and/or conversion
restrictions applicable to an Insider, as set forth in this Article IV, as a
result of changes in Rule 16b-3 under the Securities Exchange Act of 1934.

                                       V.

Disability, or death.

     5.3  FORFEITURES.  A Member who terminates employment with the Company and
its Affiliates with a Vested Interest in his Company Deferral Account that is
less than 100% shall forfeit to the Company the nonvested portion of such
Company Deferral Account as of the date of such termination.

                                   WITHDRAWALS

     6.1   IN GENERAL.  Except as provided in this Article VI and in Article 
VII, Members shall not be permitted to make withdrawals from the Plan.  
Members shall not, at any time, be permitted to borrow from the Plan.

     6.2   UNFORESEEABLE FINANCIAL EMERGENCY.  In the event that the Plan
Administrator, upon written petition of a Member, determines in its sole
discretion that such Member has suffered an Unforeseeable Financial Emergency,
such Member shall be entitled to a benefit, determined as of any Valuation Date,
in an amount not to exceed the lesser of (1) the amount determined by the Plan
Administrator as necessary to meet such Member's needs created by the
Unforeseeable Financial Emergency or (2) the then value of such Member's Vested
Interest in his Accounts.  Such withdrawal benefit shall be paid in a single
lump sum, cash payment as soon as administratively practicable after the Plan
Administrator has made its determinations with respect to the availability and
amount of such benefit.  If a Member's Account(s) contain more than one
distribution subaccount, such withdrawal benefit shall be considered to have
been distributed, first, from the subaccount with respect to which the earliest
distribution would be made, then, from the subaccount with respect to which the
next earliest distribution would be made, and continuing in such manner until
all of such subaccounts necessary to satisfy the withdrawal benefit have been
exhausted.  Moreover, within the applicable Account or subaccount, such
withdrawal benefit shall be considered to have been distributed from Deferrals
(including net income (or net loss) equivalents attributable thereto) on a
first-in, first-out basis.

     6.3   ELECTIVE WITHDRAWAL.  

          (a)  A Member may elect at any time, by effecting the election
procedure prescribed by the Plan Administrator, to withdraw as a benefit all,
but not less than all, of his Vested Interest in his Accounts as of any
Valuation Date, subject to a withdrawal penalty of 10% of the amount withdrawn. 
Upon any such withdrawal, the withdrawal penalty shall be forfeited to the
Company.  Upon any such withdrawal, such Member's participation in the Plan
shall terminate and no further Deferrals shall be made under the Plan on behalf
of such Member for the remainder of the Plan Year in which the withdrawal is
made and for the next subsequent Plan Year.

          (b)  No election of a withdrawal of an amount allocated to the Stock
Fund may be made by an Insider on a date which is less than six months following
(i) the date of any prior election to convert such Insider's deemed investment
designation which had the effect of increasing the total amount allocated to the
Stock Fund or (ii) the date of any election by such Insider with respect to any
other plan of the Parent Company or any subsidiary thereof which had the effect
(directly or indirectly) of making an acquisition on behalf of such Insider of
Common Stock.

                                      VII.

                                  DISTRIBUTIONS

     7.1   AMOUNT OF BENEFIT.  A Member or, in the event of the death of the
Member, the Member's designated beneficiary as provided in Section 7.4, shall be
entitled to a benefit equal in value to the Member's Vested Interest in his
Accounts as of the Valuation Date next preceding the date the payment of such
benefit is to be made or to commence pursuant to Section 7.2 (plus any annual
bonus Deferral not previously allocated to such Accounts).

     7.2   TIME OF PAYMENT.  Payment of a Member's benefit under Section 7.1
shall be made or commence, with respect to such Member's Accounts, or with
respect to such Member's subaccounts established pursuant to Section 3.1(h)
separately and respectively, as soon as administratively practicable as of the
date provided hereunder.  A Member may, pursuant to Section 3.1(h), elect
distribution, with respect to all or a part of his Deferrals for any Plan Year
made pursuant to Section 3.1(b) and/or 3.1(c), but not with respect to net
income equivalents thereon, to be made as of an Entry Date that is at least two
years following the end of such Plan Year.  Notwithstanding the foregoing,
payment of a Member's benefit under Section 7.1 (but excluding any distribution
elected pursuant to the preceding sentence) shall be made or commence as soon as
administratively practicable after the first day of the calendar month following
the date the Member terminates his employment with the Company and its
Affiliates for any reason, including Retirement, Disability or death.  For this
purpose, a Member on Disability for a period of two years shall be deemed to
have terminated his employment with the Company and its Affiliates as of the end
of such two-year period.

     7.3   ALTERNATIVE FORMS OF BENEFIT PAYMENTS.  A Member's benefit under
Section 7.1 payable (a) prior to termination of employment with the Company and
its Affiliates or (b) payable after termination of employment with the Company
and its Affiliates for a reason other than Retirement (inclusive of termination
due to Disability) or death, shall be paid, with respect to such Member's
Accounts, or with respect to such Member's subaccounts established pursuant to
Section 3.1(h) separately and respectively, in one lump sum payment.  A Member's
benefit under Section 7.1 payable after a Member's Retirement (inclusive of
termination due to Disability) for a reason other than death shall be paid, with
respect to such Member's Accounts, or with respect to such Member's subaccounts
established pursuant to Section 3.1(h) separately and respectively, in one of
the following forms irrevocably elected by such Member pursuant to Section
3.1(h):

          (a)  One lump sum payment; provided, that if such Member dies prior to
     the date the payment of his lump sum benefit is made, then such lump sum
     benefit shall be made to the Member's designated beneficiary as provided in
     Section 7.4; or

          (b)  Annual installment payments for a term certain of either 5, 10,
     or 15 years payable to the Member or, in the event of such Member's death
     prior to the end of such term certain, to his designated beneficiary as
     provided in Section 7.4; provided, that to the extent such Member
     designates a non-spouse beneficiary, such beneficiary's share of the
     remaining installments shall be paid in one lump sum.


                                     -11-


<PAGE>

A Member's benefit under Section 7.1 payable after a Member's termination of
employment by reason of death shall be paid, with respect to such Member's
Accounts, or with respect to such Member's subaccounts established pursuant to
Section 3.1(h) separately and respectively, in one of the following forms
irrevocably elected by such Member pursuant to Section 3.1(h):

          (c)  One lump sum payment; or

          (d)  Annual installment payments for a term certain of either 5, 10,
     or 15 years payable to the Member's designated beneficiary as provided in
     Section 7.4 or, in the event of such beneficiary's death prior to the end
     of such term certain, to such beneficiary's executor or administrator, or
     to his heirs-at-law if there is no administration of such beneficiary's
     estate.

Plan provisions to the contrary notwithstanding, if payments are to be made in
annual installments, "installment valuation dates" shall be established as of
each payment date.  As of each such "installment valuation date," net income (or
net loss) equivalents shall be allocated to the Member's Account(s) or
subaccount(s).  The installment payment to be made on behalf of a Member as of
each such "installment valuation date" shall be determined by multiplying the
balance of such Member's Account(s) or subaccount(s) as of such "installment
valuation date" (after allocation of net income (or net loss) equivalents) by a
fraction, the numerator of which is one and the denominator of which is the
number of years remaining in the installment period.

     7.4   DESIGNATION OF BENEFICIARIES.

          (a)  Each Member shall have the right to designate the beneficiary or
beneficiaries to receive payment of his benefit in the event of his death.  Each
such designation shall be made by executing the beneficiary designation form
prescribed by the Plan Administrator and filing same with the Plan
Administrator.  Any such designation may be changed at any time by execution of
a new designation in accordance with this Section.

          (b)  If no such designation is on file with the Plan Administrator at
the time of the death of the Member or such designation is not effective for any
reason as determined by the Plan Administrator, then the designated beneficiary
or beneficiaries to receive such benefit shall be as follows:

               (1)  If a Member leaves a surviving spouse, his benefit shall be
     paid to such surviving spouse;

               (2)  If a Member leaves no surviving spouse, his benefit shall be
     paid to such Member's executor or administrator, or to his heirs at law if
     there is no administration of such Member's estate.

     7.5   CHANGE IN PAY-OUT OF CERTAIN BENEFITS.  Notwithstanding any provision
in Section 7.3 to the contrary, if a Member's benefit payments respecting any
one subaccount established pursuant to Section 3.1(h) are to be paid in
installments and the aggregate amount to be paid as of 


                                     -12-


<PAGE>

the commencement of such installments with respect to such subaccount is less 
than $25,000, then the Plan Administrator shall cause the benefit payments 
with respect to such subaccount to be paid in one lump sum payment.

     7.6   ACCELERATED PAY-OUT DUE TO EMERGENCY.  Notwithstanding any provision
in Sections 7.2 and 7.3 to the contrary, in the event that the Plan
Administrator, upon written petition of a Member, determines in its sole
discretion that such Member has suffered an Unforeseeable Financial Emergency,
such Member shall be entitled to an accelerated payout of his benefit pursuant
to Section 6.2.  Any remaining amounts in such Member's Accounts following
payment of such emergency benefit shall be payable at the time(s) and in the
form(s) otherwise provided in Sections 7.2 and 7.3.

     7.7   DEFERRED PAY-OUT DUE TO LOSS OF TAX DEDUCTION.  If the Company
determines in good faith that there is a reasonable likelihood that any benefits
paid to a Member pursuant to this Article VII would not be deductible by the
Company under applicable income tax provisions then in effect, then to the
extent deemed necessary by the Company to ensure that the entire amount of any
such distribution to a Member is deductible, the Company may defer payment of
all or any portion of such benefits.  Any amount deferred pursuant to this
Section 7.7 shall continue to receive net income (or net loss) equivalents
pursuant to the Plan until distribution.  The amounts so deferred shall be
distributed to the Member (or his beneficiary in the event of the Member's
death) at the earliest possible date, as determined by the Company in good
faith, as of which such deductibility will be ensured.

     7.8   MODIFICATIONS DUE TO CHANGE IN CONTROL.  Notwithstanding any
provisions in Sections 7.2 and 7.3 to the contrary, in the event of the
occurrence of a "Change in Control," as defined in Section 12.3 of the Trust,
the Plan Administrator may, in its sole discretion, (a) change the time(s)
and/or form(s) of payment elected by such Member pursuant to Sections 3.1(h),
7.2, and 7.3 to accelerate payment, (b) trigger full vesting in a Member's
Company Deferral Account, and/or (c) terminate future Deferrals under the Plan.

     7.9   PAYMENT OF BENEFITS.  To the extent the Trust Fund has sufficient
assets, the Trustee shall pay benefits to Members or their beneficiaries, except
to the extent the Company pays the benefits directly and provides adequate
evidence of such payment to the Trustee.  To the extent the Trustee does not or
cannot pay benefits out of the Trust Fund, the benefits shall be paid by the
Company.  Any benefit payments made to a Member or for his benefit pursuant to
any provision of the Plan shall be debited to such Member's Accounts.  All
benefit payments shall be made in cash to the fullest extent practicable.

     7.10  UNCLAIMED BENEFITS.  In the case of a benefit payable on behalf of a
Member, if, after exercising reasonable diligence, the Plan Administrator is
unable to locate the Member or beneficiary to whom such benefit is payable, upon
the Plan Administrator's determination thereof, such benefit shall be forfeited
to the Company.  Notwithstanding the foregoing, if subsequent to any such
forfeiture the Member or beneficiary to whom such benefit is payable makes a
valid claim for such benefit, such forfeited benefit shall be restored to the
Plan by the Company.

Administrator.

     8.3   RECORDS AND PROCEDURES.  The Plan Administrator shall keep 
appropriate records of its proceedings and the administration of the Plan and

relating solely to himself under the Plan or to vote in any case in which his
individual right to claim any benefit under the Plan is particularly involved. 
In any case in which an individual comprising the Plan Administrator is so
disqualified to act, the remaining individuals comprising the Plan Administrator
or, if none, the Board shall decide the matter in which he is disqualified.

     8.5   COMPENSATION AND BONDING.  The Plan Administrator shall not receive
compensation with respect to its services as Plan Administrator.  The Plan
Administrator shall not be required to furnish bond or security for the
performance of its duties hereunder.

     8.6   PLAN ADMINISTRATOR POWERS AND DUTIES.  The Plan Administrator shall
supervise the administration and enforcement of the Plan according to the terms
and provisions hereof and shall have all powers necessary to accomplish these
purposes, including, but not by way of limitation, the right, power, authority
and duty:

          (a)  to make rules, regulations and bylaws for the administration of

          (c)  to correct any defect or supply any omission or reconcile any
     inconsistency that may appear in the Plan, in such manner and to such
     extent as it shall deem expedient to carry the Plan into effect for the
     greatest benefit of all interested parties;

          (d)  to employ and compensate such accountants, attorneys, investment
     advisors and other agents and employees as the Plan Administrator may deem
     necessary or advisable in the proper and efficient administration of the

          (e)  to determine all questions relating to eligibility;

          (f)  to determine the amount, manner and time of payment of any
     benefits and to prescribe procedures to be followed by Members and their
     beneficiaries in obtaining benefits;

          (g)  to make a determination as to the right of any person to a
     benefit under the Plan; and

          (h)  to receive and review reports from the Trustee as to the
     financial condition of the Trust Fund, including its receipts and
     disbursements.

     8.7   COMPANY TO SUPPLY INFORMATION.  The Company shall supply full and
timely information to the Plan Administrator relating to the Pay of all Members,
their ages, their Retirement, Disability, death or other termination of
employment and such other pertinent facts as the Plan Administrator may require.
The Company shall advise the Trustee of such of the foregoing facts as are
deemed necessary for the Trustee to carry out the Trustee's duties under the
Plan.  When making a determination in connection with the Plan, the Plan
Administrator shall be entitled to rely upon the aforesaid information furnished
by the Company.

     8.8   CLAIMS REVIEW.  In any case in which a claim for Plan benefits of a
Member or beneficiary is denied or modified, the Plan Administrator shall
furnish written notice to the claimant within ninety days (or within 180 days if
additional information requested by the Plan Administrator necessitates an
extension of the ninety-day period), which notice shall:

          (a)  State the specific reason or reasons for the denial or
     modification;

          (b)  Provide specific reference to pertinent Plan provisions on which
     the denial or modification is based;

          (c)  Provide a description of any additional material or information
     necessary for the Member, his beneficiary, or representative to perfect the
     claim and an explanation of why such material or information is necessary;
     and

          (d)  Explain the Plan's claim review procedure as contained herein.


                                     -15-


<PAGE>

In the event a claim for Plan benefits is denied or modified, if the Member, his
beneficiary, or a representative of such Member or beneficiary desires to have
such denial or modification reviewed, he must, within sixty days following
receipt of the notice of such denial or modification, submit a written request
for review by the Plan Administrator of its initial decision.  In connection
with such request, the Member, his beneficiary, or the representative of such
Member or beneficiary may review any pertinent documents upon which such denial
or modification was based and may submit issues and comments in writing.  Within
sixty days following such request for review the Plan Administrator shall, after
providing a full and fair review, render its final decision in writing to the
Member, his beneficiary or the representative of such Member or beneficiary
stating specific reasons for such decision and making specific references to
pertinent Plan provisions upon which the decision is based.  If special
circumstances require an extension of such sixty-day period, the Plan
Administrator's decision shall be rendered as soon as possible, but not later
than 120 days after receipt of the request for review.  If an extension of time
for review is required, written notice of the extension shall be furnished to
the Member, beneficiary, or the representative of such Member or beneficiary
prior to the commencement of the extension period.

     8.9   MANDATORY ARBITRATION.  If a Member or beneficiary is not satisfied
with the decision of the Plan Administrator pursuant to the Plan's claims review
procedure, such Member or beneficiary may, within 180 days of receipt of the
written decision of the Plan Administrator, request by written notice to the
Plan Administrator, that his claim be submitted to arbitration pursuant to the
arbitration procedures then in effect as adopted by the Plan Administrator. 
Such arbitration shall be the sole and exclusive procedure available to a Member
or beneficiary for review of a decision of the Plan Administrator.  In reviewing
the decision of the Plan Administrator, the arbitrator shall use the standard of
review which would be used by a Federal court in reviewing such decision under
the provisions of the Employee Retirement Income Security Act of 1974, as
amended.  The costs of such arbitration shall be apportioned by the arbitrator
between the Member or beneficiary and the Plan with a view toward apportionment
to the non-prevailing party.  The arbitrator's decision shall be final and
legally binding on both parties.  This Section shall be governed by the
provisions of the Federal Arbitration Act.

     8.10  INDEMNITY.  To the extent permitted by applicable law, the Company
shall indemnify and save harmless the Board and any individual acting as Plan
Administrator against any and all expenses, liabilities and claims (including
legal fees incurred to defend against such liabilities and claims) arising out
of their discharge in good faith of responsibilities under or incident to the
Plan.  Expenses and liabilities arising out of willful misconduct shall not be
covered under this indemnity.  This indemnity shall not preclude such further
indemnities as may be available under insurance purchased by the Company or
provided by the Company under any bylaw, agreement, vote of stockholders or
disinterested directors or otherwise, as such indemnities are permitted under
applicable law.

                             ADMINISTRATION OF FUNDS

     9.1   PAYMENT OF EXPENSES.  All expenses incident to the administration of
the Plan and Trust, including but not limited to, legal, accounting, Trustee
fees, and expenses of the Plan Administrator, shall be paid by the Company.

     9.2   TRUST FUND PROPERTY.  All income, profits, recoveries, contributions,
forfeitures and any and all moneys, securities and properties of any kind at any
time received or held by the Trustee, if any, shall be held as a commingled
Trust Fund pursuant to the terms of the Trust Agreement.  The Plan Administrator
shall maintain Account(s) in the name of each Member, but the maintenance of an
Account designated as the Account of a Member shall not mean that such Member
shall have a greater or lesser interest than that due him by operation of the
Plan and shall not be considered as segregating any funds or property from any
other funds or property contained in the commingled fund.  No Member shall have
any title to any specific asset in the Trust Fund, if any.

                                       X.

                               NATURE OF THE PLAN

     The Company intends and desires by the adoption of the Plan to recognize
the value to the Company of the past and present services of individuals covered
by the Plan and to encourage and assure their continued service with the Company
by making more adequate provision for their future retirement security.  The
Plan is intended to constitute an unfunded, unsecured plan of deferred
compensation for a select group of management or highly compensated employees of
the Company.  Plan benefits herein provided are a contractual obligation of the
Company which shall be paid out of the Trust Fund or out of the Company's
general assets.  Subject to the terms hereof and of the Trust Agreement, the
Company shall transfer money or other property to the Trustee to provide Plan
benefits hereunder, and the Trustee shall pay Plan benefits to Members and their
beneficiaries out of the Trust Fund in accordance with the terms of the Trust
Agreement.

     The Board shall establish the Trust and direct the Company to enter into
the Trust Agreement.  The Company shall remain the owner of all assets in the
Trust Fund and the assets shall be subject to the claims of Company creditors if
the Company ever becomes insolvent.  For purposes hereof, the Company shall be
considered "insolvent" if (a) the Company is unable to pay its debts as they
become due, or (b) the Company is subject to a pending proceeding as a debtor
under the United Sates Bankruptcy Code (or any successor federal statute).  The
chief executive officer of the Company and its board of directors shall have the
duty to inform the Trustee in writing if the Company becomes insolvent.  Such
notice given under the preceding sentence by any party shall satisfy all of the
parties' duty to give notice.  When so informed, the Trustee shall suspend
payments to the Members and hold the assets for the benefit of the Company's
general creditors.  If the Trustee receives a written allegation that the
Company is insolvent, the Trustee shall suspend payments to the Members and hold
the Trust Fund for the benefit of the Company's general creditors, and shall


                                     -17-


<PAGE>

determine within the period specified in the Trust Agreement whether the Company
is insolvent.  If the Trustee determines that the Company is not insolvent, the
Trustee shall resume payments to the Members.  No Member or beneficiary shall
have any preferred claim to, or any beneficial ownership interest in, any assets
of the Trust Fund.

                                       XI.

                                ADOPTING ENTITIES

      It is contemplated that other corporations, associations, partnerships or
proprietorships may adopt this Plan and thereby become the Company.  Any such
entity, whether or not presently existing, may become a party hereto by
appropriate action of its officers without the need for approval of its board of
directors or noncorporate counterpart or of the Board; provided, however, that
such entity must be an Affiliate.  The provisions of the Plan shall apply
separately and equally to each Company and its employees in the same manner as
is expressly provided for A.P.S., Inc. and its employees, except that the power
to appoint or otherwise affect the Plan Administrator or the Trustee and the
power to amend or terminate the Plan or amend the Trust Agreement shall be
exercised by the Board alone.  Transfer of employment among Companies and
Affiliates shall not be considered a termination of employment hereunder.  Any
Company may, by appropriate action of its officers without the need for approval
of its board of directors or noncorporate counterpart or the Board, terminate
its participation in the Plan.  Moreover, the Board may, in their discretion,
terminate a Company's Plan participation at any time.

                                      XII.

                                  MISCELLANEOUS

     12.1  NOT CONTRACT OF EMPLOYMENT.  The adoption and maintenance of the Plan
shall not be deemed to be a contract between the Company and any person or to be
consideration for the employment of any person.  Nothing herein contained shall
be deemed to give any person the right to remain under contract with the Company
or to be retained in the employ of the Company or to restrict the right of the
Company to discharge any person at any time nor shall the Plan be deemed to give
the Company the right to require any person to remain under contract with the
Company or remain in the employ of the Company or to restrict any person's right
to terminate his services at any time.

     12.2  ALIENATION OF INTEREST FORBIDDEN.  The interest of a Member or his
beneficiary or beneficiaries hereunder may not be sold, transferred, assigned,
or encumbered in any manner, either voluntarily or involuntarily, and any
attempt so to anticipate, alienate, sell, transfer, assign, pledge, encumber, or
charge the same shall be null and void; neither shall the benefits hereunder be
liable for or subject to the debts, contracts, liabilities, engagements or torts
of any person to whom such benefits or funds are payable, nor shall they be an
asset in bankruptcy or subject to garnishment, attachment or other legal or
equitable proceedings.


                                     -18-


<PAGE>

     12.3  WITHHOLDING.  All Deferrals and payments provided for hereunder shall
be subject to applicable withholding and other deductions as shall be required
of the Company under any applicable local, state or federal law.

     12.4  GUARANTY.  Plan provisions to the contrary notwithstanding, in the
event any Company fails to make payment of the benefits due under the Plan on
behalf of its Members, whether through the Trust or directly, APS Holding
Corporation shall be liable for and shall make payment of such benefits due as a
guarantor of such entity's obligations hereunder.  The guaranty obligations
provided herein shall be satisfied directly and not through the Trust.

     12.5  AMENDMENT AND TERMINATION.  The Board may from time to time, in their
discretion, amend, in whole or in part, any or all of the provisions of the
Plan; provided, however, that no amendment may be made that would impair the
rights of a Member with respect to amounts already allocated to his Account(s). 
The Board may terminate the Plan at any time.  In the event that the Plan is
terminated, the balance in a Member's Account(s) shall be paid to such Member or
his designated beneficiary in the manner specified by the Plan Administrator,
which may include one lump sum payment in full satisfaction of all of such
Member's or beneficiary's benefits hereunder.

invalid for any reason, said illegality or invalidity shall not affect the
remaining provisions hereof; instead, each provision shall be fully severable
and the Plan shall be construed and enforced as if said illegal or invalid
provision had never been included herein.

ACCORDANCE WITH THE LAWS OF TEXAS EXCEPT TO THE EXTENT PREEMPTED BY FEDERAL LAW.

     EXECUTED this 14th day of August, 1996.

                 EXECUTIVE 401(k) DEFERRAL PLAN TRUST AGREEMENT


     THIS AGREEMENT AND DECLARATION OF TRUST, made this 14th day of August,
1996, by and between A.P.S., INC. and TEXAS COMMERCE BANK NATIONAL ASSOCIATION
(hereinafter referred to as the "TRUSTEE").

     WHEREAS, A.P.S., INC. has established the A.P.S., INC. EXECUTIVE 401(k)
DEFERRAL PLAN (hereinafter referred to as the "PLAN") for the benefit of certain
individuals who are eligible for benefits under the terms of the Plan (such
individuals being referred to herein as the "MEMBERS"), which Plan provides for
the payment of certain deferred compensation benefits (the "BENEFITS") to the
Members and the beneficiaries of the respective Members who may become entitled
to any payments under the terms of the Plan in the event of the Member's death
("BENEFICIARIES"); and  

     WHEREAS, other adopting entities may adopt the Plan (such other adopting
entities, if any, along with A.P.S., INC. hereinafter referred to as the
"COMPANY," jointly and severally); and

     WHEREAS, the Plan contemplates that the Company will pay the entire cost of
the Benefits from its general assets; and 

     WHEREAS, A.P.S., INC. desires to establish the A.P.S., INC. EXECUTIVE
401(k) DEFERRAL PLAN TRUST AGREEMENT (the "TRUST") to aid the Company in meeting
the obligations under the Plan; and

     WHEREAS, the Trust is intended to be a "grantor trust" with the corpus and
income of the Trust treated as assets and income of the Company for federal
income tax purposes; and  

     WHEREAS, the Company intends that the assets of the Trust shall at all
times be subject to the claims of general creditors of the Company as provided
in Article X; and  

     WHEREAS, the Company intends that the existence of the Trust shall not
alter the characterization of the Plan as "unfunded" for purposes of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), and shall
not be construed to provide income to any Member prior to actual payment of
Benefits under the Plan; and

     WHEREAS, under the Trust, the Trustee covenants that it will hold all
property which it may receive hereunder, IN TRUST, for the uses and purposes and
upon the terms and conditions hereinafter stated; 



                                    -1-

     NOW, THEREFORE, the parties hereto adopt this Trust Agreement, effective
September 1, 1996, and agree, as follows:

                                    ARTICLE I

                            GENERAL TRUST PROVISIONS

     1.1  ESTABLISHMENT OF TRUST.  A.P.S., Inc. hereby adopts the Trust
Agreement, establishing the Trust with the Trustee, consisting of such sums of
money and other property acceptable to the Trustee as from time to time shall be
paid or delivered to the Trustee by the Company.  All such money and other
property, all investments and reinvestments made therewith or proceeds thereof
and all earnings and profits thereon, less all payments and charges as
authorized herein, shall constitute the "TRUST FUND."  The Trust Fund shall at
all times be subject to the claims of general creditors of the Company as
provided in Article X.  No Member or Beneficiary shall have any preferred claim
to, or any beneficial ownership interest in, any assets of the Trust Fund prior
to the time such assets are paid to such Member or Beneficiary as Benefits.

     1.2  SEPARATE SUB-TRUSTS.  Contrary provisions of the Trust
notwithstanding, except as provided in Article XI, the provisions of the Trust
shall apply separately and equally to A.P.S., Inc. and to each adopting entity
that has entered into this Trust Agreement pursuant to Article XI.  Each Company
shall bear the cost of providing Benefits for its own Members and their
Beneficiaries, and the portion of the Trust Fund attributable to the
contributions of each Company shall be available only to provide benefits to
such Company's Members and their Beneficiaries or to satisfy claims of such
Company's Bankruptcy Creditors in the event such Company becomes Insolvent (as
such terms are defined in Section 10.1).

     1.3  TRUST IRREVOCABLE.  The Trust shall be irrevocable and shall be held
for the exclusive purpose of providing benefits under the Plan to Members and
their Beneficiaries and defraying expenses of the Trust in accordance with the
provisions of this Trust Agreement.  Except as provided in Sections 3.6(c) and
3.6(d) and Articles IX and X hereof, no part of the income or corpus of the
Trust Fund shall be recoverable by or for the Company.

     1.4  NON-ALIENATION.  No right or interest to receive benefits from the
Trust may be assigned, sold, anticipated, alienated or otherwise transferred by
any Member or Beneficiary.

     1.5  ACCEPTANCE BY TRUSTEE.  The Trustee accepts the Trust established
under this Trust Agreement on the terms and subject to the provisions set forth
herein, and it agrees to discharge and perform fully and faithfully all of the
duties and obligations imposed upon it under this Trust Agreement.

                                   ARTICLE II

                          GENERAL DUTIES OF THE PARTIES

     2.1  GENERAL DUTIES OF THE COMPANY AND THE TRUSTEE.

          (a)  The Company has provided or will provide the Trustee with a copy
of the Plan and shall provide the Trustee with a copy of any amendment to the
Plan promptly upon its adoption.  The Plan, as of the date of execution of this
Trust Agreement, is hereby incorporated by reference into and shall form a part
of this Trust Agreement as fully as if set forth herein verbatim.  Any amendment
to the Plan shall also be incorporated by reference into and form a part of this
Trust Agreement, effective as of the effective date of such amendment.  Schedule
A to this Trust Agreement sets forth the name and mailing address of each Member
entitled to receive Benefits, the Beneficiaries, if any, designated by each
Member, each Member's aggregate balance ("ACCOUNT BALANCE") in the accounts
maintained under the Plan on his behalf, and each Member's vested rights
("Vested Interest") in his Account Balance.  Such Schedule (as amended from time
to time as provided herein) is hereinafter referred to as the "BENEFIT
SCHEDULE."  The Company shall be responsible for notifying the Trustee of any
changes in the information set forth on the Benefit Schedule, including, but not
limited to, the addition of new Members and a change in the mailing address of a
Member.

          (b)  Subject to the provisions of Section 2.1(c), the Trustee shall
keep the Benefit Schedule accurate and current based entirely upon information
provided by the administrator established pursuant to the Plan (the "PLAN
ADMINISTRATOR"), including but not limited to, preparing by March 31 of each
year a completely updated Benefit Schedule as of December 31 of the immediately
preceding year in order to permit distributions from the Trust Fund to be made
in accordance with the provisions of Section 3.6.  The Company shall keep
accurate books and records with respect to the eligibility of individuals to
participate in the Plan and the Benefits payable under the Plan, and shall
provide such information to the Trustee and any independent third party referred
to in the immediately preceding sentence and shall also provide access to such
books and records at such time or times as the Trustee shall reasonably request.

          (c)  If, at any time, the Company fails or refuses to give the Trustee
Member data or access to such books and records in accordance with Section
2.1(b), the Trustee shall deliver a written request to the Company to provide
access to books and records of the Company and to provide such data as required
in accordance with Section 2.1(b).  If the Company fails or refuses to comply
with the Trustee's written request pursuant to the preceding sentence prior to
the expiration of thirty days from the date of delivery thereof by the Trustee,
the Trustee shall, after ten days written notice to the Company, immediately pay
to each Member an amount equal to such Member's Vested Interest in his Account
Balance as set forth on the most recent Benefit Schedule, reduced by any taxes
to be withheld pursuant to Section 3.6.  Such payment shall be made in
accordance with the provisions of Section 3.6.  For this purpose, the Company
shall be deemed to have complied with the Trustee's written request if, in the
Trustee's judgment, it shall have substantially complied at the end of the
thirty-day period and is endeavoring in good faith to complete compliance
without delay.



                                    -3-


<PAGE>

          (d)  The Plan Administrator shall notify each Member and Beneficiary
of a then deceased Member in writing of any changes in the Benefit Schedule with
respect to such Member or Beneficiary.  The Trustee shall notify all Members and
such Beneficiaries of any failure of the Company to provide information required
in this Section 2.1.

          (e)  It is intended that Benefits payable to Members shall be
determined under the provisions of the Plan and shall be calculated under the
provisions of the Plan as of the date of payment.  The Company shall contribute
such amounts to the Trust Fund so as to provide the Benefits under the Plan. 
Payment of Benefits shall be based upon the amounts set forth on the Benefit
Schedule only under the circumstances set forth in Section 2.1(c).  If the
actual Benefits payable to a Member under the provisions of the Plan exceeds the
amount set forth on the Benefit Schedule which is paid pursuant to Section 
2.1(c), the Company shall be liable for payment of the remaining portion of such
Benefits.

          (f)  Trust provisions to the contrary notwithstanding, the Company
shall have the right at any time, and from time to time, in its sole discretion,
to substitute marketable securities of equal fair market value for any asset
held by the Trust.  This right is exercisable by the Company in a nonfiduciary
capacity without the approval or consent of any person in a fiduciary capacity.

     2.2  ADDITIONAL GENERAL DUTIES OF TRUSTEE.  The Trustee shall manage,
invest and reinvest the Trust Fund as the Trustee may determine in the exercise
of its fiduciary duties hereunder, consistent with the provisions of
Article III.  The Trustee shall collect the income on the Trust Fund, and make
distributions therefrom, all as hereinafter provided.

                                   ARTICLE III

            INVESTMENT, ADMINISTRATION AND DISBURSEMENT OF TRUST FUND

     3.1  INVESTMENT OF TRUST FUND.  The following provisions shall apply with
respect to investment of the Trust Fund:

          (a)  At any time prior to the occurrence of a Change in Control (as
     such term is defined in Section 12.3), the Trustee shall invest and
     reinvest the assets of the Trust Fund in accordance with the written
     directions received from time to time by the Trustee from the Plan
     Administrator.  Specifically, but not by way of limitation, the Plan
     Administrator may, in its discretion, direct the Trustee to follow the
     deemed investment directions of each Member or Beneficiary of a deceased
     Member, whether written or telephonic, with respect to a portion of the
     Trust Fund assets equal in value to the Account Balance maintained under
     the Plan on behalf of such individual, within parameters established by,
     and as agent for, the Plan Administrator;

          (b)  To the extent that the Trustee is directed by the Plan
     Administrator, the Trustee may invest in securities (including stock or
     rights to acquire stock) or obligations issued by the Company;



                                    -4-


<PAGE>

          (c)  To the extent that the Trustee is directed by the Plan
     Administrator, the Trustee may establish one or more separate investment
     accounts within the Trust Fund, each separate account being hereinafter
     referred to as an Investment Fund.  Except as otherwise provided, the
     Trustee shall transfer to each such Investment Fund such portion of the
     assets of the Trust Fund as the Plan Administrator directs.  The Trustee
     shall be under no duty to question, and shall not incur any liability on
     account of following, any direction of the Plan Administrator.  The Trustee
     shall be under no duty to review the investment guidelines, objectives, and
     restrictions established, or the specific investment directions given by
     the Plan Administrator for any Investment Fund, or to make suggestions to
     the Plan Administrator in connection therewith.  To the extent that
     directions from the Plan Administrator to the Trustee represent deemed
     investment elections of the Members, the Trustee shall have no
     responsibility for such investment elections and shall incur no liability
     on account of investing the assets of the Trust Fund in accordance with
     such directions.  All interest, dividends, and other income received with
     respect to, and any proceeds received from the sale or other disposition of
     securities or other property held in, an Investment Fund shall be credited
     to and reinvested in such Investment Fund.  All expenses of the Trust Fund
     which are allocable to a particular Investment Fund shall be so allocated
     and charged.  The Plan Administrator may direct the Trustee to eliminate an
     Investment Fund or Funds, and the Trustee shall thereupon dispose of the
     assets of such Investment Fund and reinvest the proceeds thereof in
     accordance with the directions of the Plan Administrator; and

          (d)  From and after the occurrence of a Change in Control, or if the
     Plan Administrator fails to provide the Trustee with such written
     directions, the Trustee shall have, with respect to the Trust Fund, power
     in its discretion to invest and reinvest such assets in (i) common and
     preferred stocks, bonds, notes and debentures (including convertible stocks
     and securities but not including any stock, debt instruments, or other
     securities of the Company, the Trustee or their affiliates) which are
     readily marketable and listed on a United States national securities
     exchange or the NASDAQ national market, (ii) interest-bearing deposit
     accounts or certificates of deposit maturing within one year after
     acquisition thereof, entered into or issued by a United States national or
     state bank or trust company having capital, surplus and undivided profits,
     at the holding company level, of at least $75 million, (iii) direct
     obligations of, and obligations fully guaranteed by, the United States of
     America or any agency of the United States of America which is backed by
     the full faith and credit of the United States of America (so long as such
     obligations shall mature within one year after acquisition thereof), (iv)
     any common, collective or commingled fund, including a fund maintained by
     the Trustee, established and maintained primarily for the purpose of
     investing and reinvesting in assets of the type described in (i), (ii) and
     (iii) above, and (v) insurance contracts issued by one or more insurance
     companies.  Further, notwithstanding the provisions of the preceding
     sentence, after the occurrence of a Change in Control or in the event the
     Plan Administrator fails to provide the Trustee with written directions
     pursuant to the first sentence of this Section, the Trustee shall have the
     power in its discretion to retain, maintain, continue, sell, or take any
     other actions relative to any assets then held in the Trust Fund
     (including, without limitation, to take actions in accordance with deemed
     investment directions obtained directly from a Member or Beneficiary of a
     deceased Member with 



                                    -5-


<PAGE>

     respect to a portion of the Trust Fund assets equal in value to the Account
     Balance maintained under the Plan on behalf of such individual).

     3.2  VALUATION OF TRUST FUND.  As soon as practicable after December 31 of
each year and as of such other dates as may be specified by the Company or the
Plan Administrator, the Trustee shall report to the Company and the Plan
Administrator the assets held in the Trust Fund as of such day and shall
determine and include in such report the fair market value as of such day of
each such asset.  In determining such fair market values, the Trustee shall use
such market quotations and other information as are available to it and may in
its discretion be appropriate.  The report of any such valuation shall not
constitute a representation by the Trustee that the amounts reported as fair
market values would actually be realized upon the liquidation of the Trust Fund.
The Trustee shall not be accountable to the Company or to any other person on
the basis of any such valuation, but its accountability shall be in accordance
with the provisions of Article IV hereof.

     3.3  ADDITIONAL INVESTMENT POWERS OF TRUSTEE.  Subject to the provisions of
Sections 3.1, 3.6 and 9.2 hereof, the Trustee shall have, with respect to the
Trust Fund, the power in its discretion:

          (a)  To retain any property at any time received by it;

          (b)  To sell, exchange, convey, transfer or dispose of, and to grant
     options for the purchase or exchange with respect to, any property at any
     time held by it;

          (c)  To register and carry any securities or any other property in the
     name of the Trustee, or in the name of the nominee of the Trustee (or to
     hold any such property unregistered) without increasing or decreasing the
     fiduciary liability of the Trustee, and to exercise any option, right or
     privilege to convert any convertible securities, including shares or
     fractional shares of the Trustee so long as the conversion privilege is
     offered pro rata to all shareholders; 

          (d)  To cause any securities to be held in book-entry or in bearer
     form;

          (e)  To hold uninvested, without liability for interest thereon, any
     moneys received by it until the same shall be invested or disbursed; and

          (f)  To hold property for investment that may be unproductive of
     income.

     3.4  ADMINISTRATIVE POWERS OF TRUSTEE.  The Trustee shall have the power in
its discretion:

          (a)  To exercise all voting rights with respect to the shares of stock
     held in the Trust Fund and to grant proxies, discretionary or otherwise;
     provided, however, voting rights with respect to stock issued by the
     Company or its affiliates shall be exercised by the Plan Administrator
     prior to the occurrence of a Change in Control;



                                    -6-


<PAGE>

          (b)  To cause any shares of stock to be registered and held in the
     name of one or more of its nominees, or one or more nominees of any system
     for the central handling of securities, without increase or decrease of
     liability;

          (c)  To collect and receive any and all money and other property due
     to the Trust Fund and to give full discharge therefor;

          (d)  Subject to the provisions of Section 3.6 hereof:  to settle,
     compromise or submit to arbitration any claims, debts or damages due or
     owing to or from the Trustee; to commence or defend suits or legal
     proceedings to protect any interest of the Trust; and to represent the
     Trust in all suits or legal proceedings in any court or before any other
     body or tribunal;

          (e)  To organize under the laws of any state a corporation or limited
     liability company for the purpose of acquiring and holding title to any
     property which it is authorized to acquire under this Trust Agreement and
     to exercise with respect thereto any or all of the powers set forth in this
     Trust Agreement;

          (f)  To determine how all receipts and disbursements shall be
     credited, charged or apportioned as between income and principal;

          (g)  To determine the amount and time of Benefit payments in
     accordance with  directions from the Plan Administrator or its delegates
     and in compliance with the provisions of Section 3.6;

          (h)  To employ and compensate such attorneys, counsel, brokers or
     other agents or employees and to delegate to them such of the duties,
     rights and powers of the Trustee as may be deemed advisable in handling and
     administering the Trust; and

          (i)  Generally to do all acts, whether or not expressly authorized,
     which the Trustee may deem necessary or desirable for the protection of the
     Trust Fund.

     3.5  DEALINGS WITH TRUSTEE.  Persons dealing with the Trustee shall be
under no obligation to see to the proper application of any money paid or
property delivered to the Trustee or to inquire into the Trustee's authority as
to any transaction.

     3.6  DISTRIBUTIONS FROM TRUST FUND.

          (a)  Except as set forth in Section 3.6(c), Section 3.6(d), Section
9.2 and Article X hereof, distributions from the Trust Fund shall be made by the
Trustee to the Members and Beneficiaries at the times and in the amounts set
forth in the Plan and, to the maximum extent permitted by applicable law, the
Trustee shall be fully protected in so doing.  Any amounts so paid shall be
reduced by the amount of any federal, state, or local income or other taxes that
may be required by law to be withheld or paid by the Trustee and the Trustee
shall withhold, pay and report such amounts to the appropriate governmental
authorities; provided, that the Company shall 



                                    -7-


<PAGE>

withhold, pay and report any FICA or FUTA taxes; and, provided, further, that 
the Company, the Plan Administrator, the Members, and the Beneficiaries shall 
provide the Trustee with all of the information necessary for the Trustee to 
determine the amount of such taxes required to be withheld or paid by the 
Trustee and the Trustee shall be fully protected in relying upon such 
information.  Notwithstanding any provision of this Trust Agreement to the 
contrary, the Company shall be obligated to pay the Benefits.  To the extent 
that the Trust Fund is not sufficient to pay any Benefit when due, the 
Company shall pay such Benefit directly.  In the event Benefits are due to 
more than one Member or Beneficiary on the same date and the Trust Fund is 
not sufficient to pay all such Benefits, the Trust Fund shall be applied pro 
rata among such Members and Beneficiaries on the basis of the Benefits due to 
be paid such individuals on such date, as determined by the Plan 
Administrator or its delegates.  Nothing in this Trust Agreement shall 
relieve the Company of its liabilities to pay Benefits except to the extent 
such liabilities are met by application of Trust Fund assets.

          (b)  Prior to the occurrence of a Change in Control, the Plan
Administrator shall direct the Trustee in writing as to the time and amount of
Benefits to be distributed to the Members and Beneficiaries.  From and after the
occurrence of a Change in Control, a Member or Beneficiary who believes that he
or she is entitled to Benefits may apply in writing directly to the Trustee for
payment of such Benefits.  Such application shall advise the Trustee of the
circumstances which entitle such Member or Beneficiary to payment of such
Benefits.  The Trustee shall, in such case, reach its own independent
determination as to the Member's or Beneficiary's entitlement to Benefits, even
though the Trustee may be informed from another source (including the Company or
the Plan Administrator) that payments are not due under the Plan.  If the
Trustee so desires, it may, in its sole discretion, make such additional
inquiries and/or take such additional measures as it deems necessary in order to
enable it to determine whether Benefits are due and payable, including, but not
limited to, interviewing appropriate persons, requesting affidavits, soliciting
oral or written testimony under oath, or holding a hearing or other proceeding. 
After the occurrence of a Change in Control, the Trustee shall determine whether
Benefits are payable as promptly as possible.

          (c)  At any time and from time to time, the Plan Administrator may
direct the Trustee in writing to distribute to the Company cash held by the
Trustee as part of the Trust Fund in an amount equal to the Benefits accrued
under the Plan that have been forfeited under the terms of the Plan.  As soon as
practicable after receipt of such a direction and, if such direction is received
by the Trustee after the occurrence of a Change in Control, the Trustee's
independent determination that such benefits have, in fact, been forfeited in
accordance with the terms of the Plan, the Trustee shall distribute such amount
to the Company.

          (d)  At any time and from time to time prior to the occurrence of a
Change in Control, the Company may apply in writing to the Trustee for a
distribution by the Trustee to the Company of assets held by the Trustee as part
of the Trust Fund ("TRUST ASSETS") in an amount (the "REFUND AMOUNT") equal to
or less than the difference, if any, between (i) the Net Fair Market Value of
the Trust Assets (as such term is hereinafter defined) as of the last day of the
month coincident with or immediately preceding the date of such application, and
(ii) the aggregate Account Balances for all Members and Beneficiaries as of such
date.  Such application shall advise the Trustee of the manner in which the
Refund Amount was calculated.  Upon the receipt of such 



                                    -8-


<PAGE>

an application from the Company, the Trustee shall reach its own independent 
determination as to the Company's entitlement to the Refund Amount, even 
though the Trustee may be informed from another source (including a Member) 
that the Company is not entitled to the Refund Amount.  If the Trustee so 
desires, it may, in its sole discretion, make such additional inquiries 
and/or take such additional measures as it deems necessary in order to enable 
it to determine whether the Company is entitled to the Refund Amount, 
including, but not limited to, interviewing appropriate persons, requesting 
affidavits, soliciting oral or written testimony under oath, or engaging such 
independent third parties as the Trustee may deem necessary to assist in 
making such determination.  The Trustee shall determine whether the Company 
is entitled to all or any portion of the Refund Amount as promptly as 
possible.  If the Trustee determines that the Company is entitled to all or 
any portion of the Refund Amount, then the Trustee shall distribute such 
amount to the Company in cash or in kind as determined by the Trustee in its 
sole discretion.  As used herein, the term "NET FAIR MARKET VALUE OF THE 
TRUST ASSETS" shall mean the fair market value of the Trust Assets, as 
determined by the Trustee in its sole discretion, reduced by all liabilities 
of the Trust, whether or not such liabilities are secured by any or all of 
the Trust Assets, other than liabilities to Members or Beneficiaries under 
the Plan.  In determining such fair market value, the Trustee shall use such 
market quotations and other information as are available to it and may in its 
discretion be appropriate; provided, however, that the fair market value of 
any life insurance contract which constitutes a portion of the Trust Assets 
shall be its net cash surrender value.  The determination of the Net Fair 
Market Value of the Trust Assets by the Trustee shall not constitute a 
representation by the Trustee that the amounts reported as fair market values 
would actually be realized upon the liquidation of the Trust Assets.  The 
Trustee shall not be accountable to the Company or to any other person, 
including the Members or Beneficiaries, on the basis of any such valuation 
except as otherwise provided in this Trust Agreement.  

          (e)  The Trustee shall not itself commence any legal action, whether
in the nature of an interpleader action, request for declaratory judgment or
otherwise, requesting a court to make a determination under Section 3.6(a), (b),
(c) or (d) hereof in the Trustee's stead without first using its best efforts to
make such determination.

          (f)  Notwithstanding any other provision of this Trust Agreement, if
any amounts held in the Trust are found in a "determination" (within the meaning
of Section 1313(a) of the Internal Revenue Code of 1986) to have been includible
in gross income of a Member or Beneficiary prior to payment of such amounts from
the Trust, the Trustee shall, as soon as practicable, pay such amounts to such
Member or Beneficiary, as applicable, (but not in excess of such Member's or
Beneficiary's Vested Interest in his Account Balance at the time of such
payment).  For purposes of this Section 3.6, the Trustee shall be entitled to
rely on an affidavit by a Member or Beneficiary, as applicable, and a copy of
the determination to the effect that a determination described in the preceding
sentence has occurred.

                                   ARTICLE IV

                             SETTLEMENT OF ACCOUNTS

     The Trustee shall keep full accounts of all of its receipts and
disbursements.  Its books and records with respect to the Trust Fund shall be
open to inspection by the Company, any Member or any Beneficiary of a deceased
Member or their representatives at all times during business hours of the
Trustee.  Within sixty days after December 31 of each year, or any termination
of the duties of the Trustee, the Trustee shall prepare, sign and mail to the
Company and the Plan Administrator an account of its acts and transactions as
Trustee hereunder.  If, within sixty days after the mailing of the account or
any amended account, the Company and the Plan Administrator have not filed with
the Trustee notice of any objection to any act or transaction of the Trustee,
the account or amended account shall become an account stated.  If any objection
has been filed, and if the objecting party is satisfied that it should be
withdrawn or if the account is adjusted to the objecting party's satisfaction,
the objecting party shall in writing filed with the Trustee signify its approval
of the account and it shall become an account stated.  When an account becomes
an account stated, such account shall be finally settled, and the Trustee shall
be completely discharged and released, as if such account had been settled and
allowed by a judgment or decree of a state or federal court of competent
jurisdiction in an action or proceeding in which the Trustee, the Company and
the Plan Administrator were parties.  The Trustee, the Company or the Plan
Administrator shall have the right to apply at any time to a state or federal
court of competent jurisdiction for judicial settlement of any account of the
Trustee not previously settled as hereinabove provided.  In any such action or
proceeding it shall be necessary to join as parties the Trustee, the Company and
the Plan Administrator and any judgment or decree entered therein shall be
conclusive upon all such parties.

                                    ARTICLE V

                   TAXES, EXPENSES AND COMPENSATION OF TRUSTEE

     5.1  TAXES.  The Company agrees that all income, deductions and credits of
the Trust Fund belong to it as owner for income tax purposes and will be
included on the Company's income tax returns.  The Company shall from time to
time pay taxes (references in this Trust Agreement to the payment of taxes shall
include interest and applicable penalties) of any and all kinds whatsoever which
at any time are lawfully levied or assessed upon or become payable in respect of
the Trust Fund, the income or any property forming a part thereof, or any
security transaction pertaining thereto.  To the extent that any taxes levied or
assessed upon the Trust Fund are not paid by the Company or contested by the
Company pursuant to the last sentence of this Section 5.1, the Trustee shall pay
such taxes out of the Trust Fund and the Company shall upon demand by the
Trustee deposit into the Trust Fund an amount equal to the amount paid from the
Trust Fund to satisfy such tax liability.  If requested by the Company, the
Trustee shall, at Company expense, contest the validity of such taxes in any
manner deemed appropriate by the Company or its counsel, but only if it has
received an indemnity bond or other security satisfactory to it to pay any
expenses of such contest.  Alternatively, the Company may itself contest the
validity of any such taxes, but any such 



                                   -10-


<PAGE>

contest shall not affect the Company's obligation to reimburse the Trust Fund 
for taxes paid from the Trust Fund.

     5.2  EXPENSES AND COMPENSATION.  The Trustee shall be paid compensation by
the Company as the Company and the Trustee may from time to time agree.  The
Trustee shall be reimbursed by the Company for its reasonable expenses of
management and administration of the Trust, including reasonable compensation of
counsel and any agent engaged by the Trustee to assist it in such management and
administration.  In the event that the Company shall fail or refuse to pay such
compensation or make such reimbursement within sixty days of demand, the Trustee
may satisfy such obligations out of the assets of the Trust Fund; in that event,
the Company shall immediately upon demand by the Trustee deposit into the Trust
Fund a sum equal to the amount paid by the Trust Fund for such fees and
expenses.

                                   ARTICLE VI

                            FOR PROTECTION OF TRUSTEE

     6.1  COMMUNICATIONS WITH THE COMPANY, THE PLAN ADMINISTRATOR AND THE
MEMBERS.

          (a)  The Company shall certify to the Trustee the name or names of any
person or persons authorized to act for the Company and for the Plan
Administrator.  Such certification shall be signed by the President or a Vice
President and the Secretary or an Assistant Secretary of the Company.  Until the
Company notifies the Trustee, in a similarly signed notice, that any such person
is no longer authorized to act for the Company or for the Plan Administrator, as
applicable, the Trustee may continue to rely upon the authority of such person.

          (b)  The Trustee may rely upon any certificate, notice or direction of
the Company or the Plan Administrator which the Trustee reasonably believes to
have been signed by a duly authorized officer or agent of the Company or the
Plan Administrator, as applicable.

          (c)  Communications to the Trustee shall be sent in writing to its
principal address, Attention:  Legal Department, or to such other address as the
Trustee may specify.  No communication shall be binding upon the Trust Fund or
the Trustee until it is received by the Trustee and unless it is in writing and
signed by an authorized person.

          (d)  Communications to the Company shall be sent in writing to the
Company at 15710 John F. Kennedy Boulevard, Suite 700, Houston, Texas  77032,
Attention:  General Counsel, or to such other address as the Company may specify
in writing to the Trustee.  Communications to the Plan Administrator shall be
sent in writing to the Company's address, Attention:  Executive 401(k) Deferral
Plan Administrator.  Communications to a Member or Beneficiary shall be sent in
writing to the address of such person as stated on the Benefit Schedule, or to
such other address as such person may specify in writing to the Trustee.  No
communication shall be binding upon the Company, the Plan Administrator, or a
Member or Beneficiary until it is received by such person.

     6.2  ADVICE OF COUNSEL.  The Trustee may consult with any legal counsel
with respect to the construction of this Trust Agreement, its duties hereunder
or any act which it proposes to take or omit, and shall not be liable for any
action taken or omitted in good faith pursuant to such advice.  Expenses of such
counsel shall be deemed to be expenses of management and administration of the
Trust within the meaning of Section 5.2 hereof.

     6.3  FIDUCIARY RESPONSIBILITY.

          (a)  The Trustee shall discharge its duties under this Trust Agreement
in effectuating the Plan in a manner consistent with the objectives of this
Trust Agreement and the Plan.  The Trustee shall not be liable for any loss
sustained by the Trust Fund by reason of the purchase, retention, sale or
exchange of any investment in good faith and in accordance with the provisions
of this Trust Agreement.  The Trustee shall have no responsibility or liability
for any failure of the Company to make contributions to the Trust Fund or for
any insufficiency of assets in the Trust Fund to pay Benefits when due.  The
Trustee shall not be liable hereunder for any act taken or omitted to be taken
in good faith, except for its own negligence or misconduct.

          (b)  The Trustee shall not be responsible for any act or failure to
act of another fiduciary except to the extent otherwise provided by law.

          (c)  No bond shall be required of the Trustee unless otherwise
required by law.

          (d)  The Trustee shall have no responsibility to negotiate any
insurance contracts respecting the Plan and Trust, nor shall the Trustee have
any responsibility to conduct any due diligence as to such insurance contracts.

          (e)  The Trustee's duties and obligations shall be limited to those
expressly imposed upon it by this Trust Agreement.

          (f)  The Company at any time may employ as agent (to perform any act,
keep any records or accounts, or make any computations required of the Company
or the Plan Administrator by this Trust Agreement or the Plan) the individual,
corporation or association serving as Trustee hereunder.  Nothing done by said
individual, corporation or association as such agent shall affect its
responsibilities or liability as Trustee hereunder.

                                   ARTICLE VII

                              INDEMNITY OF TRUSTEE

     The Company hereby indemnifies and holds the Trustee harmless from and
against any and all losses, damages, costs, expenses or liabilities (herein,
"LIABILITIES"), including reasonable attorneys' fees and other costs of
litigation, to which the Trustee may become subject pursuant to, arising out of,
occasioned by, incurred in connection with or in any way associated with this
Trust Agreement, including the acts or omissions of other fiduciaries, except
for any act or omission constituting negligence or misconduct of the Trustee. 
If one or more Liabilities shall arise, or if the Company fails to indemnify the
Trustee as provided herein, or both, then the Trustee may engage counsel of the
Trustee's choice, but at the Company's expense, either to conduct the defense
against such Liabilities or to conduct such actions as may be necessary to
obtain the indemnity provided for herein, or to take both such actions.  The
Trustee shall notify the Company within fifteen days after the Trustee has so
engaged counsel of the name and address of such counsel.  If the Trustee shall
be entitled to indemnification by the Company pursuant to this Article VII and
the Company shall not provide such indemnification upon demand, the Trustee may
apply assets of the Trust Fund in full satisfaction of the obligations for
indemnity by the Company, and any legal proceeding by the Trustee against the
Company for such indemnification shall be on behalf of the Trust.


                                  ARTICLE VIII

                       RESIGNATION AND REMOVAL OF TRUSTEE

     8.1  RESIGNATION OF TRUSTEE.  The Trustee may resign upon sixty days' prior
written notice to the Board of Directors of A.P.S., Inc. (the "BOARD"), the Plan
Administrator, each Member and each Beneficiary of a deceased Member, except
that any such resignation shall not be effective until the Board have appointed
in writing a successor trustee, which must be a bank, trust company, or an
individual, and such successor has accepted the appointment in writing;
provided, however, that if such appointment is to become effective at any time
after the occurrence of a Change in Control, then the consent of a majority of
the Members to the appointment of such successor trustee must be obtained.  For
all purposes of this Trust Agreement where the consent of a majority of the
Members is required, the determination of majority consent shall be based upon
receiving the consent of any combination of Members whose sum of Account
Balances as of the time of determination is greater than fifty percent of the
sum of Account Balances for all Members at such time, rather than upon receiving
the consent of a majority of the number of Members.  For purposes of this
determination, Beneficiaries of deceased Members shall be considered Members. 
The Board shall make a good faith effort, following receipt of notice of
resignation from the Trustee, to find and appoint a successor Trustee who will
adhere to the obligations imposed on such successor under the terms of this
Trust Agreement, and in particular, but without limitation, the obligation to
exercise judgment independent of the Company in the circumstances described in
Section 3.6 hereof.  The appointment of a successor trustee shall also be
conditioned upon obtaining from such successor a written statement that the
successor has read the Trust Agreement and understands its obligations
thereunder.  If the consent of a majority of the Members is required for the
appointment of a 



                                   -13-


<PAGE>

successor Trustee, then the Trustee shall be responsible for securing such 
Member consents in a timely fashion and, unless ordered by a court of 
competent jurisdiction, shall not reveal to the Board, the Plan Administrator 
or any other person any information concerning such consents, except whether 
the required majority has been achieved.  Any notice sent to Members by the 
Trustee canvassing the Members as to their consent to a successor trustee, 
shall include the name and address of the proposed successor trustee.  Any 
consent of a Member required under this Section 8.1 shall be deemed given if 
no written objection is received by the Trustee from such Member within 
fourteen days after request for such consent is sent postpaid by United 
States registered or certified mail with return receipt requested to such 
Member.  Provisions of the Trust Agreement to the contrary notwithstanding, 
if the Trustee gives notice of resignation to the Plan Administrator and no 
successor Trustee has been appointed within sixty days of receipt of such 
written notice, the compensation of the Trustee then in effect shall increase 
by 50%, effective as of the lapse of such sixty-day time period.

     8.2  REMOVAL OF TRUSTEE.  The Board may remove the Trustee upon sixty days'
prior written notice to the Trustee, the Plan Administrator, each Member and
each Beneficiary of a deceased Member, except that any such removal shall not be
effective until the close of such notice period and (a) delivery by the Board to
the Trustee of an instrument in writing appointing a successor trustee meeting
the requirements of Section 8.1, and (b) an acceptance of such appointment in
writing executed by such successor.  Notwithstanding the provisions of the
preceding sentence, if such appointment of a successor trustee is to become
effective at any time after the occurrence of a Change in Control, then the
removal of the Trustee and the appointment of a successor trustee shall not be
effective until the Trustee has received the consent of a majority of the
Members (as determined in accordance with the provisions of Section 8.1 hereof)
to such removal and such appointment.  Upon the receipt by the Trustee of a
written notice of removal, the Trustee shall be responsible for securing the
Member consents (if such consents are required pursuant to the preceding
provisions of this Section 8.2) in a timely fashion and, unless ordered by a
court of competent jurisdiction, shall not reveal to the Board, the Plan
Administrator or any other person any information concerning such consents,
except whether the  required majority has been achieved.  Any notice sent to
Members by the Trustee canvassing the Members as to their consent to removal of
the Trustee and the appointment of a proposed successor trustee, shall include
the name and address of the proposed successor trustee.  Any consent of a Member
required under this Section 8.2 shall be deemed given if no written objection is
received by the Trustee from such Member within fourteen days after request for
such consent is sent postpaid by United States registered or certified mail with
return receipt requested to such Member.

     8.3  SUCCESSOR TRUSTEE.  All of the provisions set forth herein with
respect to the Trustee shall relate to each successor with the same force and
effect as if such successor had been originally named as the Trustee hereunder.



                                   -14-


<PAGE>

     8.4  TRANSFER OF TRUST FUND TO SUCCESSOR.  Upon the resignation or removal
of the Trustee and appointment of a successor, the Trustee shall transfer and
deliver the Trust Fund to such successor.  Following the effective date of the
appointment of the successor, the Trustee's responsibility hereunder shall be
limited to managing the assets in its possession and transferring such assets to
the successor, and settling its final account.  Neither the Trustee nor the
successor shall be liable for the acts of the other.  


                                   ARTICLE IX

                 DURATION AND TERMINATION OF TRUST AND AMENDMENT

     9.1  DURATION AND TERMINATION.  The Trust is hereby declared to be
irrevocable and shall continue until (a) all payments required by Section 3.6
have been made or (b) until the Trust Fund contains no assets and retains no
claims to recover assets from the Company or any other person or entity,
whichever shall first occur.  Notwithstanding the preceding provisions of this
Section 9.1, unless earlier terminated, the Trust shall terminate twenty-one
(21) years after the death of the last to die of all of the Members and their
issue living on the date of execution of this Trust Agreement; provided,
however, that if at that time the Trust may be continued in force without
violating the rule against perpetuities or any other law of the State of Texas,
then the Trust shall remain in effect until otherwise terminated as provided
hereunder.

     9.2  DISTRIBUTION UPON TERMINATION.  If this Trust terminates under the
provisions of Section 9.1, the Trustee shall liquidate the Trust Fund and, after
its final account has been settled as provided in Article IV, shall distribute
to the Company the net balance of any assets of the Trust remaining after all
expenses have been paid and all Benefits, whether or not due and payable under
the terms of the Plan on the date of such termination, have been paid to the
Members and Beneficiaries.  Upon making such distribution, the Trustee shall be
relieved from all further liability.  The powers of the Trustee hereunder shall
continue so long as any assets of the Trust Fund remain in its hands.

     9.3  AMENDMENT.  The Board may from time to time amend, in whole or in
part, any or all of the provisions of this Trust Agreement; provided, however,
that (a) no amendment will be made to this Trust Agreement or the Plan which
will cause this Trust Agreement, the Plan or the assets of the Trust Fund to be
governed by or subject to Part 2, 3 or 4 of Title I of ERISA, (b) no such
amendment shall adversely affect any Benefits to the date of such amendment in
respect of any Member or Beneficiary or the amount of assets of the Trust Fund
available to pay such Benefits, (c) no such amendment shall purport to alter the
irrevocable character of the Trust established under this Trust Agreement, (d)
no such amendment shall increase the duties or responsibilities of the Trustee
unless the Trustee consents thereto in writing, and (e) after the occurrence of
a Change in Control, no amendment will be made to this Trust Agreement without
the consent of a majority of the Members (as determined pursuant to the
provisions of Section 8.1 hereof).  Upon receipt of a request from the Board for
an amendment which requires the consent of a majority of the Members, the
Trustee shall be responsible for securing Member consents in a timely fashion,
and unless ordered by a court of competent jurisdiction, shall not reveal to the
Board, the Plan Administrator or any other person any information concerning
such consents, except whether the required majority has 



                                   -15-


<PAGE>

been achieved.  Any consent of a Member required under this Section 9.3 shall 
be deemed given if no written objection is received by the Trustee from such 
Member within fourteen days after request for such consent is sent postpaid 
by United States registered or certified mail with return receipt requested 
to such Member.  This Trust Agreement may be amended, to the extent permitted 
in this Section 9.3, by an instrument in writing executed on behalf of 
A.P.S., Inc. by its authorized representatives, consents to which instrument 
have been obtained from the required majority of Members if such consents are 
required.


                                    ARTICLE X

                          CLAIMS OF COMPANY'S CREDITORS

     10.1  INSOLVENCY OF COMPANY.  As used in this Article X, the Company shall
be deemed to be "INSOLVENT" if (a) the Company is unable to pay its debts as
they come due, or (b) the Company is subject to a pending proceeding as a debtor
under the United States Bankruptcy Code (or any successor federal statute).  In
the event that the Company shall be deemed Insolvent, the assets of the Trust
Fund shall be held for the benefit of the general creditors of the Company
(hereinafter referred to as "BANKRUPTCY CREDITORS").

     10.2  TRUSTEE'S RESPONSIBILITIES IF COMPANY MAY BE INSOLVENT.

           (a)  If at any time the Company or a person claiming to be a creditor
of the Company alleges in writing to the Trustee that the Company has become
Insolvent, the Trustee shall within thirty days independently determine whether
the Company is Insolvent and, pending such determination, the Trustee shall
discontinue any payment of Benefits under the Plan and this Trust Agreement and
shall hold the Trust Fund for the benefit of Bankruptcy Creditors.  As a
condition of being a Member of the Plan and this Trust Agreement, each Member
hereby waives his priority credit position, if any, under applicable state law. 
The Trustee shall resume payments of Benefits under the Plan and this Trust
Agreement in accordance with Section 3.6 hereof only after the Trustee has
determined that the Company is not Insolvent (or is no longer Insolvent, if the
Trustee initially determined the Company to be Insolvent) or upon receipt of an
order of a court of competent jurisdiction requiring such payments.  The
Company, by its chief executive officer and its Board of Directors, shall
further be obligated to give the Trustee prompt notice in writing in the event
that the Company becomes Insolvent, with the same consequences as provided in
the preceding two sentences.  In determining whether the Company is Insolvent,
the Trustee may rely conclusively upon, and shall be protected in relying upon,
court records showing that the Company is Insolvent, or a current report or
statement from a nationally recognized credit reporting agency showing that the
Company is Insolvent.  For purposes of this Trust Agreement, knowledge and
information concerning the Company which is not in the possession of the
Trustee, or its employees, shall not be imputed to the Trustee.  The Trustee
shall have no duty or obligation to ascertain whether the Company is Insolvent
unless and until it receives a writing that the Company is Insolvent as
described in the first or third sentence of this Section 10.2(a).

          (b)  If the Trustee determines that the Company is Insolvent, the
Trustee shall hold the assets of the Trust Fund for the benefit of the
Bankruptcy Creditors, and shall disburse the assets of the Trust Fund to satisfy
such claims as a court of competent jurisdiction shall direct.

          (c)  If the Trustee discontinues payment of Benefits pursuant to
Section 10.2(a) and subsequently resumes such payments, the first payment to a
Member or Beneficiary following such discontinuance shall include an aggregate
amount equal to the difference between the payments that would have been made to
such Member or Beneficiary, as applicable, under this Trust Agreement but for
this Section 10.2 and the aggregate payments actually made to such Member or
Beneficiary, as applicable, by the Company pursuant to the Plan during any such
period of discontinuance.  In the event that upon resumption of payments
pursuant to the preceding sentence, the assets of the Trust Fund are
insufficient to pay Benefits in full, Benefit payments to the affected Members
and Beneficiaries shall be prorated so as to equitably apportion the assets of
the Trust Fund among all affected Members and Beneficiaries in proportion to
their Benefits.

     10.3  TRUST RECOVERY OF PAYMENTS TO CREDITORS.  In the event that at any
time an amount is paid from the Trust Fund to Bankruptcy Creditors of the
Company, the Trustee shall demand that the Company deposit into the Trust Fund a
sum equal to the amount paid by the Trust Fund to such Bankruptcy Creditors and,
if such payment is not made within ninety days of such demand, the Trustee shall
take such action as it deems prudent or advisable to recover payment.


                                   ARTICLE XI

                                ADOPTING ENTITIES

     It is contemplated that other corporations, associations, partnerships or
proprietorships that have adopted the Plan may adopt this Trust Agreement and
thereby become the Company.  Any such entity, whether or not presently existing,
may become a party hereto by appropriate action of its officers without the need
for approval of its board of directors or noncorporate counterpart or of the
Board.  The provisions of the Trust Agreement shall apply separately and equally
to each Company and its Members and their Beneficiaries in the same manner as is
expressly provided for A.P.S., Inc. and its Members and their Beneficiaries,
except that (a) the power to appoint or otherwise affect the Trustee and the
power to amend the Trust Agreement shall be exercised by the Board alone, and
(b) the determination of whether a Change in Control has occurred shall be based
solely on A.P.S. Holding Corporation.


                                   ARTICLE XII

                                  MISCELLANEOUS

     12.1 LAWS OF THE STATE OF TEXAS TO GOVERN.  This Trust Agreement and the
Trust hereby created shall be construed and regulated by the laws of the State
of Texas.

     12.2  TITLES AND HEADINGS NOT TO CONTROL.  The titles to Articles and
headings of Sections in this Trust Agreement are placed herein for convenience
of reference only and, in case of any conflict, the text of this Trust
Agreement, rather than such titles or headings, shall control.

     12.3  CHANGE IN CONTROL.  As used in this Trust Agreement, the term "CHANGE
IN CONTROL" shall mean the occurrence of one or more of the following events: 
(a) A.P.S. Holding Corporation shall not be the surviving entity in any merger,
consolidation or other reorganization to which it is a party (or survives only
as a subsidiary of an entity other than a previously wholly-owned subsidiary of
A.P.S. Holding Corporation); (b) A.P.S. Holding Corporation sells, leases or
exchanges all or substantially all of its assets to any other person or entity
(other than a wholly-owned subsidiary of A.P.S. Holding Corporation); (c) A.P.S.
Holding Corporation is dissolved and liquidated or adopts a plan of dissolution
and liquidation; (d) any person or entity, including a "group" as contemplated
by Section 13(d)(3) of the Securities Exchange Act of 1934, as amended, acquires
or gains ownership or control (including, without limitation, power to vote) of
more than 50% of the outstanding shares of A.P.S. Holding Corporation's voting
stock (based upon voting power); or (e) as a result of or in connection with a
contested election of directors, the persons who were directors of A.P.S.
Holding Corporation before such election shall cease to constitute a majority of
the Board.  Notwithstanding the foregoing, any sale of the outstanding shares of
A.P.S. Holding Corporation held by Clayton & Dubilier Fund IV to a third party
shall not be deemed to be a Change in Control.  A.P.S. Holding Corporation, by
its chief executive officer and its Board of Directors, shall be obligated to
give the Trustee prompt notice in writing of the occurrence of a Change in
Control.  In the event the Trustee receives such a notice or if at any time a
Member or a Beneficiary of a deceased Member alleges in writing to the Trustee
that a Change in Control has occurred, the Trustee shall within thirty days
independently determine whether a Change in Control has occurred and, pending
such determination, the Trustee shall assume that a Change in Control has
occurred for all purposes of this Trust Agreement and the Plan.  The Trustee
shall have no duty or obligation to ascertain whether a Change in Control has
occurred unless it receives a written notice as described in either of the
preceding two sentences.  In determining whether a Change in Control has
occurred, the Trustee may, in its sole discretion, make such additional
inquiries and/or take such additional measures as it deems necessary, including,
but not limited to, interviewing appropriate persons, requesting affidavits,
soliciting oral or written testimony under oath, or engaging such independent
third parties as the Trustee may deem necessary to assist in making such
determination.  Notwithstanding the foregoing, if at any time A.P.S. Holding
Corporation notifies the Trustee in writing that the Trustee should interpret
this Trust Agreement and the Plan as if a Change in Control had occurred, then
for all purposes of this Trust Agreement and the Plan, the Trustee shall so
interpret this Trust Agreement and the Plan.  Once the notice described in the
preceding sentence is received by the Trustee, it may not be rescinded by A.P.S.
Holding Corporation.

     12.4  SUCCESSORS AND ASSIGNS.  This Trust Agreement may not be assigned by
either party without the prior written consent of the other, and any purported
assignment without such prior written consent shall be null and void.  This
Trust Agreement shall be binding upon the successors and permitted assigns of
each party hereto.

     12.5 CONTROLLING DOCUMENT.  Should an inconsistency or conflict exist
between the specific terms of this Trust Agreement and those of the Plan, then
the relevant terms of this Trust Agreement shall govern and control.

     IN WITNESS WHEREOF, the parties hereto have caused this Trust Agreement to
be executed as of the day and year first above written.

                       [OPINION OF E. EUGENE LAUVER, ESQ.]


                                 August 15, 1996


APS Holding Corporation
World Houston Plaza
15710 John F. Kennedy Blvd.
Suite 700
Houston, Texas 77032-2347

Ladies and Gentlemen:

     As Vice President and General Counsel of APS Holding Corporation, a
Delaware corporation (the "Company"), I have represented the Company in
connection with the approval by the Board of Directors of the Company of the
A.P.S., Inc. Executive 401(k) Deferral Plan (the "Plan"), and the registration
pursuant to a Registration Statement on Form S-8 being filed with the Securities
and Exchange Commission (the "Registration Statement") under the Securities Act
of 1933, as amended (the "Act"), of the offering and issuance of the Deferred
Compensation Obligations of the Company under the Plan (the "Deferred
Compensation Obligations"), which includes the purchase by the Plan in the open
market of shares of Company Common Stock, par value $.01 per share (the
"Shares").

     This opinion is delivered in accordance with the requirements of
Item 601(b)(5) of Regulation S-K under the Act.

     In this connection, I have examined certain corporate records of the
Company, including its Second Restated Certificate of Incorporation, its Bylaws,
as amended, and minutes of meetings (or unanimous consents in lieu of meetings)
of its directors, the corporate proceedings of the Company with respect to the
adoption by the Board of Directors of the Plan and the A.P.S., Inc. Executive
401(k) Deferral Plan Trust Agreement, dated as of August 14, 1996, between
A.P.S., Inc. and Texas Commerce Bank National Association, as Trustee (the
"Trust Agreement").  I have also examined the Registration Statement (in the
form to be filed with the Securities and Exchange Commission), together with the
Plan, the Trust Agreement, other exhibits thereto and such other documents as I
have deemed necessary for the purpose of expressing the opinions contained
herein.  I am rendering this opinion as of the date on which the Registration
Statement becomes effective.

     Based on the foregoing, I am of the opinion that (i) the Plan and the Trust
Agreement have been duly and validly approved by the Company, (ii) the Deferred
Compensation Obligations have been duly and validly authorized by the Company,
and (iii) the Shares have been validly authorized and issued and are fully paid
and nonassessable.


<PAGE>

     I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of my name in the Registration Statement. 
In giving this consent, I do not thereby admit that I am within the category of
persons whose consent is required under Section 7 of the Act and the rules and
regulations thereunder.

                                       Very truly yours,

                                       /s/ Eugene Lauver
                                       ----------------------------------

                       CONSENT OF INDEPENDENT ACCOUNTANTS
