                Shareholder, apart from remuneration accrued and expenses
                incurred by such Selling Management Shareholder on behalf of the

        5.1.4   there is not, nor is there any agreement or arrangement to
                create, any Lien under the laws of Luxembourg or any other
                jurisdiction on, over or affecting any of the Sale Shares held
                by such Selling Management Shareholder and no person is entitled
                to claim any of the foregoing.

5.2     In consideration of the Purchaser entering into this Agreement and
        agreeing to make payments to the Company in accordance with the
        provisions of Clause 5.10 of and Part A of Schedule 5 to the Shareholder
        Agreement, the Company and (to the extent specified in Schedule 4)
        certain of the Selling Management Shareholders warrant, represent and
        undertake that the warranties set out in Schedule 2 are true, accurate
        and not misleading as of the date hereof subject to disclosures made in
        the Disclosure Letter of even date herewith. The warranties given by the
        Selling Management Shareholders and set out in Clause 5.1 and the
        warranties given by the Company and set out in Schedule 2 are
        hereinafter sometimes referred to collectively as "the Warranties".

5.3     Each of the Warranties shall be separate and severable and shall not be
        limited by reference to or inference from any other Warranty.

5.4     Each Selling Management Shareholder and the Company acknowledges that
        the Purchaser is entering into this Agreement in reliance upon the
        Warranties given by him or it, all of which have been made and/or given
        with the intention of inducing the Purchaser to enter into this
        Agreement.

5.5     The liability of each Selling Management Shareholder under Clause 5.1
        shall be limited to the amount received by him for the sale of his Sale
        Shares and such amounts received by each Selling Management Shareholder
        shall not be deemed to be reduced by any Tax paid thereon as a
        consequence of the transfer of such, Sale Shares pursuant to this
        Agreement.

5.6     The Company and each of the Selling Management Shareholders undertakes
        that, should any of them become aware of any circumstances giving or
        likely to give rise to a claim for breach of a Warranty given by it or
        him, it or he will notify the Purchaser as soon as practicable after
        becoming so aware.

5.7     The aggregate liability of the Company and the Co-Warrantors (as defined
        in Schedule 4) pursuant to Clause 5.2 shall not exceed Pound
        Sterling 18,000,000.

5.8     No claim may be made against the Company or the Co-Warrantors (as
        defined in Schedule 4 to this Agreement) pursuant to this Clause 5:

        (a)     unless notice of such claim is served on the Company and the
                Co-Warrantors in writing specifying in reasonable detail the
                nature of such claim and the amount claimed before:

        (i)     in respect of all Warranties relating to taxation, six years;
                and

        (ii)    otherwise, two years;

                from the Completion Date;

<PAGE>   11

        (b)     unless such notice is served as soon as reasonably practicable,
                and in any event within sixty (60) days, of the Purchaser or any
                of its officers receiving actual knowledge thereof;

        (c)     unless notice of such claim is served on the Company and the
                Co-Warrantors in accordance with this Clause 5.8 and within
                twelve (12) months thereafter legal proceedings in respect of
                such claim shall have been issued and served upon the Company or
                the Co-Warrantors or the Purchaser and the Company or the
                Co-Warrantors have agreed to settle such claim; or

        (d)     which arises from a breach which is capable of remedy unless and
                until the Company is given notice of such breach and such breach
                is not remedied within thirty (30) days of the date upon which
                notice is received.

5.9     The service of a notice of claim on the Company pursuant to Clause 5.8
        shall result in the suspension of the requirement to issue and serve
        legal proceedings in respect of the underlying cause of action referred
        to in Clause 5.8(c). Provided that the requirements of Clause 5.8 have
        been met, no delay resulting from implementation by the Purchaser of the
        set-off against the Contingent Deferred Payments, as permitted by
        paragraph 3 and required by paragraph 4 of Schedule 4, shall give rise
        to a defence against the Purchaser's subsequent attempts under
        paragraphs 5 or 6 of Schedule 4 to collect the balance owed with respect
        to any claim.

5.10    Once notice of a claim has been served on or brought against the
        Company, the Company shall not distribute any Contingent Deferred
        Payments then or thereafter in its possession or under its control until
        such claim has been paid in full or withdrawn. The foregoing
        notwithstanding, the Company may distribute that portion, if any, of the
        Contingent Deferred Payments which exceed the sum of the Determined
        Amount (as defined in Schedule 4) plus interest thereon and costs of
        collection as provided by paragraph 7 of Schedule 4.

5.11    The limitations contained in Clauses 5.5, 5.7 and 5.8 shall not apply
        where there has been fraud or deceit or wilful non-disclosure on the
        part of (as the case may be) the relevant Selling Management Shareholder
        or the Company.

6       SET-OFF

        The mechanism under which the Purchaser will off-set such amounts owed
        to it in respect of any breach of the Warranties is as set out in
        Schedule 4 to this Agreement.

7.      ANNOUNCEMENTS

        Except as otherwise permitted by the Shareholder Agreement no party to
        this Agreement shall make or permit any person connected with it or them
        to make any media announcement or issue any press or media statement or
        press or media release with respect to this Agreement or any matter
        contained herein or ancillary hereto without obtaining the prior written
        agreement of the others to the contents thereof, such agreement not to
        be unreasonably withheld or delayed.

        Company, and shall not take effect until the assignee has entered into a
        Deed of Adherence in accordance with the Shareholder Agreement. No other
        party shall be entitled without the prior written consent of the other
        parties to this Agreement to assign or transfer either the benefit or

        writing.

9.4     The rights and remedies of the Purchaser under this Agreement are

        counterparts by one or more parties, each counterpart shall be deemed to
        be an original hereof.

               REPRESENTATIONS AND WARRANTIES OF TCW/EMCO HOLDING

                TCW/EMCO Holding hereby represents and warrants to PM Holdings
that:

                4.1     Organization. Each of TCW/EMCO Holding and the TCW/LAP

The TCW/LAP Fund has the requisite power and authority to execute and deliver

                4.3     Consents and Approvals; No Violations. Neither the
execution and delivery of the TCW Documents by TCW/EMCO Holding or the TCW/LAP
Fund nor the consummation by TCW/EMCO Holding or the TCW/LAP Fund of the
transactions contemplated hereby or thereby will (a) conflict with or result in
any breach of any provision of the operating agreement of limited partnership
(or similar organizational document) of TCW/EMCO Holding or the TCW/LAP Fund;
(b) result in a violation or breach of any license, contract, lease, agreement,

Notwithstanding the foregoing, both PM Holdings and TCW/EMCO Holding acknowledge
and agree that neither the execution and delivery of this Agreement or the

                4.4     Investment Representation. TCW/EMCO Holding is
acquiring the TCW/EMCO Shares for investment for its own account, not as a
nominee or agent, and not with a view to, or for resale in connection with, any
distribution thereof in violation of the Securities Act.

                4.5     Brokers; Finders and Fees. Neither TCW/EMCO Holding, the
TCW/LAP Fund nor any of their Subsidiaries or Affiliates has entered into any
agreement or arrangement entitling any agent, broker, investment banker,
financial advisor or other firm or Person to any broker's or finder's fee or any
other commission or similar fee in connection with this Agreement or the
Ancillary Agreements or the transactions contemplated hereby or thereby.

                4.6     Matters Relating to TCW/EMCO Holding. The TCW/LAP Fund
is the sole member of TCW/EMCO Holding owning 100% of the Equity Interests
therein. The investment by TCW/EMCO Holdings in the Company is permitted under
the organizational documents of the TCW/LAP Fund. TCW/EMCO Holding was formed on
September 24, 1999 and has carried on no business whatsoever except for the
entering into of this Agreement and other agreements related hereto and in
connection with the transactions contemplated hereby and thereby. Except
pursuant to or in connection with this Agreement or any Ancillary Agreement,
immediately prior to the Closing, TCW/EMCO Holding had no liabilities or
obligations of any nature whatsoever (whether direct, indirect, accrued,
contingent or otherwise). Upon the sale to TCW/EMCO Holding of the TCW Shares to
be pledged to PM Holdings to secure Promissory Note No. 2 (the "Pledged
Shares"), no Liens other than those contemplated by the Ancillary Agreements
will exist on the Pledged Shares (assuming that the representations and
warranties made by PM Holdings in Section 3.5(b) are true and correct).

                4.7     Capital Call. The TCW/LAP Fund has made an irrevocable
capital call of its limited partners to fund the payment of the cash portion of

such capital call, subject to bankruptcy, insolvency, reorganization,
moratorium, fraudulent conveyance and other similar laws of general application
affecting enforcement of creditors' rights generally in each case as applicable
to the TCW/LAP Fund or the limited partners (but not the Company) and general
principles of equity. Such capital call cannot be rescinded or returned by the
TCW/LAP Fund after the Closing Date except by the TCW/LAP Fund (which TCW/LAP
Fund agrees not to so rescind or return), and

                                       32
<PAGE>   37

contains no conditions precedent that will not have been met if the Closing
hereunder occurs, subject in each case to bankruptcy, insolvency,
reorganization, moratorium, fraudulent conveyance and other similar laws of
general application affecting enforcement of creditors' rights generally in each
case as applicable to the TCW/LAP Fund or the limited partners (but not the
Company) and general principles of equity.

                4.8     Litigation. There is no action, suit, proceeding or
governmental investigation pending or, to the knowledge of TCW/EMCO Holding,
threatened against or by, TCW/EMCO Holding by or before any court or

                (a)     From time to time prior to the Closing, PM Holdings
shall promptly supplement or amend the Disclosure Schedule with respect to any
matter arising after the delivery thereof pursuant hereto that, if existing at,
or occurring on, the date of this Agreement, would have been required to be set
forth or described in the Disclosure Schedule. Any such supplement or amendment
that relates to a representation or warranty in Article III hereof for the
period after the execution of this Agreement until the Closing shall be deemed
to constitute an exception to the representation and warranty for such period,
but only for purposes of Section 8.2(a) hereof (provided that any TCW Damages
otherwise attributable thereto shall be included in determining whether the
threshold in Section 8.2(c)(i) has been met) and only to the extent of the
breach specifically disclosed to TCW/EMCO Holding, if either: (i) TCW/EMCO
Holding shall not have objected in writing to such exception within five
Business Days (but in no event later than the Business Day immediately preceding

the Disclosure Schedule made after the execution hereof by PM Holdings pursuant
to this Section 5.4 or otherwise shall be deemed to cure any breach of any
representation of or warranty made pursuant to this Agreement.

                (b)     PM Holdings shall give notice to TCW/EMCO Holding

event whose occurrence or non-occurrence would be likely to cause either (A) any
representation or warranty contained in this Agreement to be untrue or
inaccurate in any material respect at any time from the date hereof to the
Closing Date or (B) any condition set forth in Article VI to be unsatisfied in
any material respect at any time from the date hereof to the Closing Date and
(ii) any material failure of PM Holdings, Phoenix or the EMCO Group or any
officer, director, employee or agent thereof, to comply with or satisfy any
covenant, condition or agreement to be complied with or satisfied by it
hereunder or under the Ancillary Agreements;

remedies available hereunder to TCW/EMCO Holding.

                (c)     From time to time prior to the Closing, TCW/EMCO Holding
shall promptly supplement or amend the representations and warranties made in
Article IV with respect to any matter arising after the delivery hereof that if
existing at, or occurring on, the date of this Agreement, would have rendered
such representation or warranty inaccurate. Any such supplement or amendment
that relates to a representation or warranty in Article IV for the period after
the execution of this Agreement until the Closing shall be deemed to constitute
an exception to the representation and warranty for such period, but only for
purposes of Section 8.3(a) hereof (provided that any PM Damages otherwise
attributable thereto shall be included in determining whether the threshold in
Section 8.3(c)(i) has been met) and only to the extent of the breach
specifically disclosed to PM Holdings, if either: (i) PM Holdings shall not have
objected in writing to such exception within five Business Days (but in no event
later than the Business Day immediately preceding the Closing Date) of the
receipt of such supplement or amendment or (ii) if PM Holdings shall have so
objected but shall nevertheless proceed to consummate the Closing. Except as
provided above, no supplement or amendment of any such representation or
warranty made after the execution hereof by TCW/EMCO Holding pursuant to this
Section 5.4 or otherwise shall be deemed to cure any breach of any
representation of or warranty made pursuant to this Agreement.

                (d)     TCW/EMCO Holding shall give notice to PM Holdings
promptly after becoming aware of (i) the occurrence or non-occurrence of any
event whose occurrence or non-occurrence would be likely to cause either (A) any
representation or warranty contained in this Agreement to be untrue or
inaccurate in any material respect at any time from the date hereof to the
Closing Date or (B) any condition set forth in Article VI to be unsatisfied in
any material respect at any time from the date hereof to the Closing Date and
(ii) any material failure of TCW/EMCO Holding or any officer, director, employee
or agent thereof, to comply with or satisfy any covenant, condition or agreement
to be complied with or satisfied by it hereunder; provided, however, that,
except as provided in Section 5.4(c), the delivery of any notice pursuant to
this Section shall not limit or otherwise affect the remedies available
hereunder to PM Holdings.

their respective Affiliates shall issue or cause the publication of any press
release or

the transactions contemplated hereby or thereby without prior consultation with
the other Party, except as may be required by Law or by any listing agreement

                5.6     Contact with Customers and Suppliers. TCW/EMCO Holding
(and all of its agents and Affiliates and any of its or its Affiliates'
employees, directors or officers) may contact and communicate with the
employees, customers, suppliers and licensors of the Company and its

warranty contained in Article III of this Agreement when made or at and as of

<PAGE>   48

made at and as of the date hereof and the Closing Date, and (ii) any breach of

the aggregate amount of TCW Damages, as finally determined, exceeds such amount;
and (ii) in no event will the TCW Indemnitees be entitled to indemnification
under Section 8.2(a)(i) with respect to any particular breach or inaccuracy
unless the amount of such breach or inaccuracy alone, or together with any other
matters arising out of significantly related facts and circumstances, involves
TCW Damages in excess of US$10,000, nor shall the TCW Indemnitees be entitled
to aggregate indemnification under Section 8.2(a)(i) in excess of US$40,000,000;
provided, however, that no such limitations under either clause (i) or (ii)
above shall apply to the reimbursement or indemnification for TCW Damages
arising from any third-party claims described in Section 8.4.

                (d)     The indemnity provided in this Section 8.2 shall be the
sole and exclusive remedy of TCW/EMCO Holding (and any of its Affiliates)
against PM Holdings (and any of its Affiliates), in respect of any inaccuracy or
breach of any representation, warranty or covenant of PM Holdings in this
Agreement and the sale and purchase of the TCW Shares contemplated hereby (but
not with respect to breaches of any Ancillary Agreement), except in respect of
injunctive and other similar non-monetary relief or remedies and except for
claims based on fraud). Each of PM Holdings and TCW/EMCO Holding hereby
acknowledges that it has relied solely on the representations, warranties and
covenants of TCW/EMCO Holdings or PM Holdings, as applicable, pursuant to this
Agreement and the Ancillary Agree-

                                       44

ments and on no other statements, reports or other information furnished by or
on behalf of such Person or its Affiliates.

                (e)     In the event there is an Event of Default (as such term
is defined in the Notes) under any Note, PM Holdings may deduct the amount due
and unpaid on such Note from any amounts due to TCW/EMCO Holding under this
Section 8.2.

                8.3     TCW/EMCO Holding's Agreement to Indemnify. (a) Subject
to the terms and conditions set forth herein (including without limitation
Section 9.7(e)), from and after the Closing, TCW/EMCO Holding shall indemnify
and hold harmless PM Holdings, the Company and their respective directors,
officers, employees, Affiliates, controlling Persons, agents and representatives
and their successors and assigns (collectively, the "PM Indemnitees"), from and
against all liability, demands, claims, actions or causes of action,
assessments, losses, damages, costs and expenses (including, without limitation,
attorneys' fees and expenses) (collectively, "PM Damages") asserted against or
incurred by any PM Indemnitee as a result of or arising out of (i) subject to
the expiration of the Survival Period in Section 8.1, a breach of or inaccuracy
in any representation or warranty contained in Article IV of this Agreement when
made or at and as of the Closing Date as though such representation and warranty
were made at and as of the date hereof and the Closing Date, and (ii) any breach
of any of the covenants and agreements of TCW/EMCO Holding contained in this
Agreement. For purposes of this Article VIII, in determining whether there has
been any breach of or inaccuracy in any representation or warranty contained in
Article IV of this Agreement, any qualification, limitation or exception in any
representation or warranty as to "Material Adverse Effect" or "material" or
similar qualification shall be of no force and effect.

                (b)     No claim for the recovery of any PM Damages under
Section 8.3(a)(i) may be asserted by a PM Indemnitee after the expiration of the
applicable Survival Period; provided, however, that claims in writing made by a
PM Indemnitee with reasonable specificity prior to the expiration of the
applicable Survival Period shall not thereafter be barred by the expiration of
the applicable Survival Period.

                (c)     (i) No reimbursement for PM Damages asserted under
Section 8.3(a)(i) shall be required unless and until the cumulative aggregate
amount of such PM Damages exceeds US$1,000,000 and then only to the extent that
the aggregate amount of PM Damages, as finally determined, exceeds such amount,
and (ii) in no event will the PM Indemnitees be entitled to indemnification
under Section 8.3(a)(i)

                                       45

<PAGE>   50
with respect to any particular breach or inaccuracy unless the amount of such
breach or inaccuracy, alone, or together with any other matter arising out of
significantly related facts and circumstances, involves PM Damages in excess
of US$10,000, nor shall the PM Indemnities be entitled to aggregate
indemnification under Section 8.3(a)(i) in excess of US$40,000,000; provided,
however, that no such limitations under either clauses (i) or (ii) above shall
apply to the reimbursement or indemnification for PM Damages arising (A) due to
a breach or inaccuracy of a representation or a warranty relating to the
authority to conduct the transactions contemplated hereby or (B) from any
third-party claim described in Section 8.4.

                (d)     The indemnity provided in this Section 8.3 shall be the
sole and exclusive remedy of PM Holdings (and any of its Affiliates) against
TCW/EMCO Holding (and any of its Affiliates), in respect of any inaccuracy or
breach of any representation, warranty or covenant of TCW/EMCO Holding in this
Agreement and the sale and purchase of the TCW Shares contemplated hereby (but
not with respect to breaches of any Ancillary Agreement), except in respect of
injunctive and other similar non-monetary relief or remedies and except for
claims based on fraud. Each of PM Holdings and TCW/EMCO Holding hereby
acknowledges that it has relied solely on the representations, warranties and
covenants of TCW/EMCO Holdings or PM Holdings, as applicable, pursuant to this
Agreement and the Ancillary Agreements and on no other statements, reports or
other information furnished by or on behalf of such Person or its Affiliates.

                8.4     Third Party Indemnification. The obligations of PM
Holdings to indemnify the TCW Indemnitees under Section 8.2 hereof with respect
to TCW Damages, and of TCW/EMCO Holding to indemnify PM Holdings under Section
8.3 hereof with respect to PM Damages, in either case resulting from any
assertion of liability by third parties, whether pursuant to any investigation,
regulatory or governmental proceeding, legal action or other dispute (each, as
the case may be, a "Claim"), will be subject to the following terms and
conditions:

                (a)     Any party against whom any Claim is asserted (the
"Indemnified Party") will give the other party (the "Indemnifying Party")
written notice of any such Claim promptly after learning of such Claim, and the
Indemnifying Party may at its option undertake the defense thereof by
representatives of its own choosing. Failure of the Indemnified Party to give
prompt notice of a Claim hereunder shall not affect the Indemnifying Party's
obligations under this Section 8.4(a), except to the extent the Indemnifying
Party is materially prejudiced by such failure to give prompt notice. If the
Indemnifying Party, within seven days after notice of any such Claim

                                       46
<PAGE>   51

or such shorter period as is reasonably required, fails to assume the defense of
such Claim, the Indemnified Party against whom such claim has been made will
(upon no further notice to the Indemnifying Party) have the right to undertake
the defense, compromise or settlement of such Claim on behalf of and for the
account and risk, and at the expense, of the Indemnifying Party, subject to the
right of the Indemnifying Party, to assume the defense of such Claim at any time
prior to settlement, compromise or final determination thereof.

                (b)     Notwithstanding anything in this Section 8.4 to the
contrary, the Indemnifying Party shall not enter into any settlement or
compromise of any action, suit or proceeding or consent to the entry of any
judgment (i) which does not include as an unconditional term thereof the
delivery by the claimant or plaintiff to the Indemnified Party of a written
release from all liability in respect of such action, suit or proceeding or (ii)
for other than monetary damages to be borne by the Indemnifying Party, without
the prior written consent of the Indemnified Party, which consent shall not be
unreasonably withheld.

                (c)     TCW/EMCO Holding and PM Holdings shall cooperate fully
in all aspects of any investigation, defense, pre-trial activities, trial,
compromise, settlement or discharge of any claim in respect of which indemnity
is sought pursuant to this Article VIII, including, but not limited to, by
providing the other party with reasonable access to employees and officers
(including as witnesses) and other information.

                8.5     Other Indemnification Matters. In the event that
TCW/EMCO Holding or PM Holdings Transfers (as that term is defined in the
Shareholders Agreement) any TCW/EMCO Shares or PM Holdings Shares, as the case
may be, to any Person in compliance with the Shareholders Agreement, the
non-transferring Party agrees that any such Person shall be entitled to the
benefits of the indemnification provisions hereunder as if it and its related
parties were included in the definition of TCW Indemnitees or PM Indemnitees, as
the case may be, hereunder.

Exhibits hereto and thereto and the Confidentiality Agreement) (a) constitutes
the entire agreement between the Parties with respect to the subject matter
hereof and supersedes other prior agreements and understandings, both written
and oral, between the parties hereto with respect to the subject matter hereof
and (b) shall not be assigned, by operation of Law or otherwise, by either
Party, without the prior written consent of the other Party; provided, however,
that either Party may assign any of its rights and obligations hereunder to any
transferee of its Shares permitted by the Shareholders Agreement without any
such consent.

                9.4     Severability. The invalidity or unenforceability of any
term or provision of this Agreement in any situation or jurisdiction shall not
affect the validity or enforceability of the other terms or provisions hereof or
the validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction and the remaining terms and provisions
shall remain in full force and effect.

                9.6     Dispute Resolution. In the event of any dispute,
controversy or claim arising out of or relating to this Agreement (including any
provision of any Schedule or Exhibit hereto) or the breach, termination or
validity thereof (a "Dispute"), upon the written request (a "Dispute Notice") of
either Party to this Agreement, the matter shall immediately be referred to
senior officers for resolution. The senior officers shall meet immediately and
attempt in good faith to negotiate a resolution of the Dispute. If the parties
are unable to resolve the Dispute within ten days after receipt of a Dispute
Notice, then either party may submit the Dispute to the Specified Courts in
accordance with the procedures set forth in Section 9.7.

                9.7     Governing Law; Waiver of Jury Trial.

                (a)     THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO
CONTRACTS MADE AND PERFORMED IN SUCH STATE, WITHOUT REGARD TO THE CONFLICTS OF
LAWS, RULES AND PRINCIPLES THEREOF.

                (b)     Each of PM Holdings and TCW/EMCO Holding hereby submits
to the exclusive jurisdiction of the federal and state courts in the Borough of
Manhattan in The City of New York and any appellate court therefrom (the
"Specified Courts") in any suit, action or proceeding arising out of or relating
to this Agreement, the Ancillary Agreements to which they are parties or the
transactions contemplated hereby or thereby (a "Related Proceeding"). Each of PM
Holdings and TCW/EMCO Holding waives any objection to Related Proceedings in any
Specified Court whether on the grounds of venue, residence or domicile or on the
ground that the Related Proceedings have been brought in an inconvenient forum.
PM Holdings irrevocably appoints CT Corporation System, presently located at 111
8th Avenue, New York, New York 10011 (the "Process Agent"), as the authorized
agent in the

                                       50
<PAGE>   55
Borough of Manhattan in The City of New York upon which process may be served
on PM Holdings in any Related Proceeding.  PM Holdings represents and warrants
that the Process Agent has agreed to act as agent for service of process, and
PM Holdings agrees to take any and all action, including the filing of any and
all documents and instruments, that may be necessary to continue such
appointment in full force and effect as aforesaid.  If the Process Agent shall
cease to act as PM Holdings' agent for service of process, PM Holdings shall
appoint without delay another such agent and notify the other party of such
appointment.  With respect to any such action in any New York State or United
States federal court in the Borough of Manhattan, The City of New York, service
of process upon the Process Agent and written notice of such service to PM
Holdings shall be deemed, in every respect, effective service of process upon
PM Holdings.

                (c)     TCW/EMCO Holding agrees that, should it no longer
maintain its executive offices in The City of New York it shall irrevocably
appoint CT Corporation System, at the address set forth above, as the
authorized agent in the Borough of Manhattan in The City of New York upon which
process may be served on TCW/EMCO Holding in any Related Proceeding.

                (d)     To the extent permitted by Law, PM Holdings and
TCW/EMCO Holding each waives trial by jury in any action instituted hereunder.

                (e)     PM Holdings and TCW/EMCO Holding each expressly waives
any right to recover, pursuant to Article 8 or otherwise, punitive,
incidental, indirect or consequential damages in any action instituted
hereunder; provided, however, that the foregoing shall not prevent either party
from recovering lost profits damages to the extent constituting direct damages.

                9.8     Descriptive Headings.  The descriptive headings herein
are inserted for convenience of reference only and shall in no way be construed
to define, limit, describe, explain, modify, amplify or add to the
interpretation, construction or meaning of any provision of, or scope or intent
of, this Agreement nor in any way affect this Agreement.

                9.9     Counterparts.  This Agreement may be executed in
counterparts, each of which shall be deemed an original, but all of which
collectively shall constitute one and the same instrument.

<PAGE>   56
                9.10    No Third Party Beneficiaries.  This Agreement is for
the benefit of PM Holdings and its successors and permitted assigns, and, in
the case of Article VIII, the PM Indemnitees, with respect to the obligations
of TCW/EMCO Holding under this Agreement, and for the benefit of TCW/EMCO
Holding and its successors and permitted assigns, and, in the case of Article
VIII hereof, the TCW Indemnitees, with respect to the obligations of PM
Holdings under this Agreement, and this Agreement shall not be deemed to confer
upon or give to any other third party any remedy, claim of liability or
reimbursement, cause of action or other right.

                9.11    No Waivers.  Except as otherwise expressly provided
herein, no failure to exercise, delay in exercising, or single or partial
exercise of any right, power or remedy by any Party, and no course of dealing
between the Parties, shall constitute a waiver of any such right, power or
remedy.  No waiver by a Party of any default, misrepresentation or breach of
warranty or covenant hereunder, whether intentional or not, shall be deemed to
extend to any prior or subsequent default, misrepresentation or breach of
warranty or covenant hereunder or affect in any way any rights arising by
virtue of any prior or subsequent such occurrence.  No waiver shall be valid
unless in writing and signed by the Party against whom such waiver is sought to
be enforced.

                9.12    Certain Limitations.  Except as provided in the final
sentence of this Section 9.12, it is the explicit intent and understanding of
each of the Parties that neither Party nor any of its Affiliates,
representatives or agents is making any representation or warranty whatsoever,
oral or written, express or implied, other than as provided in or pursuant to
this Agreement or any of the Ancillary Agreements and neither Party is relying
on any statement, representation or warranty, oral or written, express or
implied, made by the other Party or such other Party's Affiliates,
representatives or agents except as set forth in or pursuant to this Agreement
or the Ancillary Agreements.  The Parties acknowledge that the foregoing shall
not limit claims based on fraud.

                9.13    Further Action.  Each Party shall execute and deliver
such certificates and other documents and take such other actions as may
reasonably be requested by the other Party in order to consummate or implement
the transactions contemplated hereby.

                9.14    Interpretation.  Any references in this Agreement to
the "best knowledge" or "knowledge" of the Company or the EMCO Group shall mean
the knowledge of any member of senior management of the Company, any of the EMCO

                                       52
<PAGE>   57
Group, any director of the Company or of any of the EMCO Group and any Vice
President or more senior officer or other employee having direct oversight
responsibilities for the Company and the EMCO Group of PM Holdings, of a type
that such person would obtain in the reasonable conduct of his or her duties
and responsibilities.  Any reference in this Agreement to the "best knowledge"
or "knowledge" of TCW/EMCO Holding or the TCW/LAP Fund shall mean the knowledge
of any member of senior management of such Person, of a type that such person
would obtain in the reasonable conduct of his or her duties and
responsibilities.  The disclosure of any matter in the Disclosure Schedules
shall not be deemed to constitute an admission by PM Holdings, or to otherwise
imply, that any such matter is material for the purposes of this Agreement.
