                     REPRESENTATIONS AND WARRANTIES OF IWC

          IWC hereby represents and warrants to Havenwood and Newco as follows
that:

          SECTION 2.01.  Organization and Qualification; Subsidiaries.  Each of
IWC, its wholly owned subsidiaries Hell Fighters, Inc., a Texas corporation, and

existing and in good standing under the laws of the jurisdiction of its
incorporation or organization, has all requisite corporate or other power and
authority to own, lease and operate its properties and to carry on its business
as it is now being conducted, and is duly qualified and in good standing to do
business in each jurisdiction in which the nature of the business conducted by
it or the ownership or leasing of its properties makes such qualification
necessary. Hell Fighters, Inc., International Well Control Services, Ltd., and
IWC de Venezuela, S.A. are IWC's only directly or indirectly owned subsidiaries.

          SECTION 2.02.  Articles of Incorporation and By-Laws.  IWC has
heretofore furnished to Havenwood complete and correct copies of the Articles of
Incorporation and the By-Laws or the equivalent organizational documents, in
each case as amended or restated, of IWC and the Subsidiaries.  Neither IWC nor
any Subsidiary is in violation of any of the provisions of its respective
Articles of Incorporation or By-Laws or equivalent organizational documents.
<PAGE>
 
          SECTION 2.03.  Capitalization.  (a) The authorized capital stock of
IWC consists of 50,000,000 shares of common stock, $0.01 par value ("IWC
Common") and 5,000,000 shares of preferred stock, $0.01 par value ("IWC
Preferred").  As of the date hereof (i) 6,740,000 shares of IWC Common and no
shares of IWC Preferred, are issued and outstanding, all of the issued and
outstanding shares of IWC Common are duly authorized, validly issued, fully paid
and nonassessable and not subject to preemptive rights created by statute, IWC's
Articles of Incorporation or By-Laws or any agreement to which IWC is a party or
bound (ii) a presently indeterminate number of shares of IWC Common are reserved
for issuance upon the exercise of warrants to purchase shares of IWC Common
having an aggregate value of $3,000,000 based on a conversion price equal to
one-half of the average closing bid price of the IWC Common during the 60-day
period commencing 30 days after the completion of a public stock offering or
business combination transaction that results in the creation of a public market
for the IWC Common ("IWC Warrants") and (iii) 850,000 shares of IWC Common are
reserved for issuance at a price of $1.00 per share upon the exercise of
outstanding common stock purchase options ("IWC Options"). The IWC Common; IWC
Preferred, IWC Warrants and IWC Options are referred to herein, collectively, as

indebtedness issued or outstanding having the right to vote on any matters on
which IWC's stockholders may vote.  Except for the IWC Warrants and IWC Options
set forth in Schedule 2.03(a), there are no options, warrants, calls or other
rights (including registration rights), agreements, arrangements or commitments
presently outstanding obligating IWC to issue, deliver or sell shares of its
capital stock or debt securities, or obligating IWC to grant, extend or enter
into any such option, warrant, call or other such right, agreement, arrangement
or commitment.  Schedule 2.03(a) sets forth a true and complete list of all IWC
Warrants and IWC Options, showing for each warrant or option holder the number
of shares of IWC Common for which such warrants or options are exercisable (or
the basis for the determination thereof), the exercise price(s) thereof (or the
basis for the determination thereof), the date(s) of grant, the date(s) of
expiration and the vesting date(s) thereof, all as of the date hereof.

          (b) In addition to the IWC Securities, IWC has previously sold
$3,000,000 aggregate principal amount of 12% Senior Subordinated Notes due
December 31, 2000 ("IWC Notes"). The IWC Notes are held beneficially and
proportionally by the holders of IWC Warrants and immediately after the
consummation of the transactions contemplated hereby, IWC intends to offer the
holders of IWC Notes an opportunity, for a period of 30 days, to convert such
notes into common stock at a price of $0.75 per share.

          (c) All the outstanding shares of capital stock of the Subsidiaries
are duly authorized, validly issued, fully paid and nonassessable and such
shares are owned by IWC as set forth in Section 2.01 free and clear of any
security interests, liens, claims, pledges, agreements, limitations on voting
rights, charges or other encumbrances of any nature whatsoever ("Encumbrances").
There are no options, warrants, calls or other rights (including registration
rights), agreements, arrangements or commitments of any character to which IWC
or any Subsidiary is a party relating to the issued or unissued capital stock
of, or other equity interests in, any Subsidiary.

          SECTION 2.04.  Authority.  IWC has all requisite corporate power and

hereunder and to consummate the transactions contemplated herein.  The execution

of IWC is necessary to authorize this Agreement or to consummate the
transactions contemplated herein.  This Agreement has been duly executed and
delivered by IWC and, assuming the due authorization, execution and delivery

or hereafter in effect relating to or affecting creditors' rights generally, and
without limitation, the effect of statutory or other laws regarding fraudulent

imposed by general rules of equity (regardless of whether such enforceability is
considered at law or in equity).

          SECTION 2.05.  No Conflict; Required Filings and Consent.  (a)  The
execution and delivery of this Agreement by IWC does not, and the performance of

date of this Agreement and applicable to IWC or any Subsidiary or by which their
respective properties is bound or subject, or (iii) result in any breach of or
constitute a default (or an event that with notice or lapse of time or both
would become a default) under, or give to others any rights of termination,
amendment, acceleration or cancellation of, or require payment under, or result
in the creation of an Encumbrance on, any of the properties or assets of IWC or
any Subsidiary pursuant to any note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation
to which IWC or any Subsidiary is a party or by which IWC or any Subsidiary or
their respective properties is bound or subject except for breaches, defaults,

obligations or liens or Encumbrances that would not have a material adverse
effect on the business, properties, assets, condition (financial or otherwise)

Material Adverse Effect").

          (b) The execution and delivery of this Agreement by IWC does not, and
the performance of this Agreement by IWC will not, require IWC to obtain any
consent, approval, authorization or permit of, or to make any filing with or
notification to, any governmental or regulatory authority, domestic or foreign
("Governmental Entities") based on laws, rules, regulations and other
requirements of Governmental Entities in effect as of the date of this
Agreement, except for applicable requirements, if any, of (i) federal or state
securities laws and the filing and recordation of appropriate merger documents
as required by the TBCA and (ii) where the failure to obtain such consents,
approvals, authorizations or permits, or to make such filings or notifications,
would not, either individually or in the aggregate, prevent IWC from performing
its obligations under this Agreement or have a IWC Material Adverse Effect.

          SECTION 2.06.  Permits; Compliance. IWC and each of its Subsidiaries
is in possession of all franchises, grants, authorizations, licenses, permits,
easements, variances, exemptions, consents, certificates, approvals and orders

action, proceeding or investigation pending or, to the knowledge of
<PAGE>
 
IWC, threatened, regarding suspension or cancellation of any of IWC Permits.
Neither IWC nor any Subsidiary is in conflict with, or in default or violation
of (a) any Law applicable to IWC or any Subsidiary or by which any of their
respective properties is bound or subject or (b) any of the IWC Permits, except

Material Adverse Effect.

Subsidiaries and Boots & Coots and its subsidiaries as of the dates thereof.

          SECTION 2.08.  No Undisclosed Liabilities.  Except for the obligations

          SECTION 2.09.  Absence of Certain Changes or Events.  Except as and to

                                  ARTICLE III
             REPRESENTATIONS AND WARRANTIES OF HAVENWOOD AND NEWCO

          Havenwood and Newco hereby jointly and severally represent and warrant
to IWC that:

          SECTION 3.01.  Organization and Qualification.  Each of Havenwood and
Newco is a corporation, duly organized, validly existing and in good standing
under the laws of the jurisdiction of its incorporation and has all requisite
power and authority to own, lease and operate its properties and to carry on its
business as it is now being conducted, and is duly qualified and in good
standing to do business in each jurisdiction in which the nature of the business
conducted by it or the ownership or leasing of its properties makes such
qualification necessary.

          SECTION 3.02.  Articles of Incorporation and By-Laws.  Havenwood has
heretofore furnished to IWC a complete and correct copy of the Articles of
Incorporation and the By-Laws, as amended or restated to the date hereof, of

of the provisions of its Articles of Incorporation or By-Laws.

          SECTION 3.03.  Capitalization. (a)  Prior to the execution of this
agreement Havenwood had 258,365,000 shares of common stock ("Old Shares") issued
and outstanding. In accordance with the requirements of Delaware Law,
Havenwood's stockholders approved and Havenwood effected a "reverse split" in
the ratio of one new share ("New Shares") for every 135 Old Shares held by a
stockholder, provided, however, that no single stockholder's ownership was
reduced to fewer than 100 New Shares. Immediately prior to the execution of this
Agreement, certain principal stockholders of Havenwood surrendered a total of
740,740 New Shares to Havenwood for cancellation, leaving a total of 1,173,074
shares of Common Stock issued and outstanding.

          (b) The authorized capital stock of Havenwood consists of 50,000,000
shares of common stock, $.00001 par value ("Havenwood Common") and 5,000,000
shares of preferred stock, $0.00001 par value ("Havenwood Preferred").  As of
the date hereof (before giving effect to the transactions contemplated herein)
(i) 1,173,074 shares of Havenwood Common are issued and outstanding, all of
which are duly authorized, validly issued, fully paid and nonassessable and not
subject to preemptive rights created by statute, Havenwood's Articles of
Incorporation or By-Laws or any agreement to which Havenwood is a party or is
bound and (ii) no shares of Havenwood Preferred are outstanding.  There are no
options, warrants, calls or other rights (including registration rights),
agreements, arrangements or commitments presently outstanding obligating
Havenwood to issue, deliver, sell or register shares of its capital stock or
debt securities, or obligating Havenwood to grant, extend or enter into any such
option, warrant, call or other such right, agreement, arrangement or commitment.
<PAGE>
 
          (c) All of the outstanding shares of capital stock of Newco are duly
authorized, validly issued, fully paid and nonassessable, and are owned by
Havenwood free and clear of any Encumbrances.  There are no options, warrants,
calls or other rights (including registration rights), agreements, arrangements
or commitments of any character to which Havenwood or Newco is a party relating
to the issued or unissued capital stock of, or other equity interests in, Newco
or obligating Havenwood or Newco to grant, issue or sell any shares of the
capital stock of Newco; other than as contemplated in this Agreement and the
Subscription Agreement between Havenwood and Newco.

          (d) The shares of Havenwood Common issued to Newco and exchanged
pursuant to the Merger as contemplated herein, upon issuance in accordance with
this Agreement and the Plan, will be duly authorized, validly issued, fully paid
and nonassessable and will not be subject to preemptive rights created by
statute, Havenwood's Articles of Incorporation or By-Laws or any agreement to
which Havenwood is a party or is bound.

          (e) The Havenwood Warrants issued to Newco and exchanged pursuant to
the Merger as contemplated herein, upon issuance in accordance with this
Agreement and the Plan, will be duly authorized and validly issued, and
constitute the legal, valid and binding obligation of Havenwood enforceable in
accordance with their terms.

          (f) The Havenwood Options issued to Newco and exchanged pursuant to
the Merger as contemplated herein, upon issuance in accordance with this
Agreement and the Plan, will be duly authorized and validly issued, and
constitute the legal, valid and binding obligation of Havenwood enforceable in
accordance with their terms.

          (g) Other than SST Productions, Inc., Havenwood does not have any
subsidiaries or own any interest in any enterprise (whether or not such
enterprise is a corporation) except for Newco. Havenwood has either sold to
third parties, or dissolved in accordance with applicable law, all other
corporations, partnerships and other incorporated or unincorporated enterprises
in which it has previously had an interest, regardless of whether such interest
arose from stock ownership, management control or otherwise.

          SECTION 3.04.  Authority.  Each of Havenwood, Newco, Mark Leibovit and
Slatkin has all requisite corporate or other appropriate power and authority to
execute and deliver this Agreement, to perform its obligations hereunder and to
consummate the transactions contemplated herein.  The execution and delivery of
this Agreement and the consummation of the transactions contemplated herein have
been duly authorized by all necessary corporate action and no other corporate
proceeding on the part of Havenwood or Newco (including, without limitation, any
approval by the shareholders of Havenwood of this Agreement or the transactions
contemplated herein) is necessary to authorize this Agreement or to consummate
the transactions contemplated herein.  This Agreement has been duly executed and
delivered by Havenwood, Newco, Mark Leibovit and Slatkin and, assuming the due
authorization, execution and delivery hereof by IWC, constitutes the legal,
valid and binding obligation of Havenwood, Newco, Leibovit and Slatkin
enforceable in accordance with its terms (i) except as limited by bankruptcy,
insolvency, reorganization, moratorium or other similar law now or hereafter in
effect relating to or affecting creditors' rights generally, and without
limitation, the effect of statutory or other laws regarding fraudulent
conveyances and preferential transfers and (ii) subject to the limitations
<PAGE>
 
imposed by general rules of equity (regardless of whether such enforceability is
considered at law or in equity).

          SECTION 3.05.  No Conflict; Required Filings and Consents.  (a) The
execution and delivery of this Agreement by Havenwood and Newco does not, and
the performance of this Agreement by Havenwood and Newco will not (i)  conflict
with or violate the Certificate of Incorporation or By-Laws, as amended or
restated, of Havenwood or Newco, (ii) conflict with or violate any Laws in
effect as of the date of this Agreement applicable to Havenwood or Newco or by
which any of their respective properties is bound, or (iii) result in any breach
of or constitute a default (or an event that with notice or lapse of time or
both would become a default) under, or give to others any rights of termination,
amendment, acceleration or cancellation of, or require payment under, or result
in the creation of a lien or Encumbrance on, any of the properties or assets of
Havenwood or Newco pursuant to, any note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation
to which Havenwood or Newco is a party or by which Havenwood or Newco or any of
their respective properties is bound or subject except for breaches, defaults,
events, rights of termination, amendment, acceleration or cancellation, payment
obligations or liens or Encumbrances that would not have a material adverse
effect on the business, properties, assets, condition (financial or otherwise)
operations or prospects of Havenwood and its subsidiaries, taken as a whole, or
on the transactions herein contemplated ("Havenwood Material Adverse Effect").

          (b) The execution and delivery of this Agreement by Havenwood and
Newco and the performance of this Agreement by Havenwood and Newco does not
require Havenwood or Newco to obtain any consent, approval, authorization or
permit of, or to make any filing with or notification to, any Governmental
Entities, except for applicable requirements, if any, of (i) the Securities Act
of 1933, as  amended (the "Securities Act"), the Securities Exchange Act of
1934, as amended (the "Exchange Act") or the securities laws of any other
jurisdiction (the "Blue Sky Laws"), the National Association of Securities
Dealers, and the filing and recordation of appropriate merger documents as
required by TBCA and (ii) where the failure to obtain such consents, approvals,
authorizations or permits, or to make such filings or notifications, would not,
either individually or in the aggregate, prevent Havenwood from performing its
obligations under this Agreement or have a Havenwood Material Adverse Effect.

          SECTION 3.06.  Permits; Compliance.  Each of Havenwood and Newco is in
possession of all franchises, grants, authorizations, licenses, permits,
easements, variances, exemptions, consents, certificates, approvals and orders
necessary to own, lease and operate its properties and to carry on its business
as it is now being conducted (collectively, the "Havenwood Permits"), and there
is no action, proceeding or investigation pending or, to the knowledge of
Havenwood, threatened, regarding suspension or cancellation of any of the
Havenwood Permits.  Neither Havenwood nor Newco is in conflict with, or in
default or violation of (a) any Law applicable to Havenwood or Newco or by which
any of their respective properties is bound or subject or (b) any of the
Havenwood Permits, except for any such conflicts, defaults or violations which
would not have a Havenwood Material Adverse Effect.  Neither Havenwood nor Newco
has received from any Governmental Entity any written notification with respect
to possible conflicts, defaults or violations of Laws.

threatened against Havenwood or Newco or any properties or rights of Havenwood
or Newco and neither Havenwood nor Newco is subject to any continuing order of,

          SECTION 3.13.  Brokers.  No broker, finder or investment banker is
entitled to any brokerage, finder's or other fee or commission in connection
with the transactions contemplated in this Agreement based upon arrangements
made by or on behalf of Havenwood or Newco.

indenture or other evidence of indebtedness or guaranty or security for

                             ADDITIONAL AGREEMENTS

          SECTION 4.01.  Appropriate Action; Consents; Filings.  IWC and
Havenwood shall each use its best efforts to (i) take, or cause to be taken, all
appropriate action, and do, or cause to be done, all things necessary, proper or

necessary filings, and thereafter make any other required submissions, with
respect to this Agreement and the Merger required under (A) the Securities Act
and the Exchange Act and the rules and regulations thereunder (in the case of
Havenwood), and any other applicable federal or state securities laws and (B)
any other applicable Law.  IWC and Havenwood shall furnish all information

Slatkin (collectively the "Indemnitors") jointly and severally covenants and
agrees that it will indemnify the stockholders of IWC exchanging IWC Common, IWC
Warrants and IWC Options in connection with the Merger ("IWC Stockholders") and
Havenwood (after the Merger) from and against any Loss (as hereinafter defined)
asserted against, resulting to, imposed upon or incurred or suffered, directly
or indirectly (for example, on account of a Loss incurred by Havenwood after the
date hereof), by such IWC Stockholders or and Havenwood (after the Merger)
resulting or arising from any of the following ("IWC Indemnified Claims"):

          (i)  Any inaccuracy in any of the representations and warranties made
               by Havenwood or Newco herein or in any exhibit or schedule
               attached hereto or any facts or circumstances constituting such
               inaccuracy; and

          (ii) Any breach or nonfulfillment by Havenwood or Newco of the
               covenants or agreements set forth herein or in any exhibit or
               schedule attached hereto or any facts or circumstances
               constituting such breach or nonfulfillment;

provided, however, that IWC Stockholders and Havenwood (after the Merger) shall,
in the event of a claim for such indemnification, be entitled to reimbursement
for Losses in connection with such claim only as provided herein.

     (b) IWC covenants and agrees that it will indemnify the stockholders of
Havenwood prior to the Merger ("Havenwood Stockholders") from and against any
Loss asserted against,
<PAGE>
 
resulting to, imposed upon or incurred or suffered, directly or indirectly (for
example, on account of a Loss incurred by Havenwood after the date hereof), by
such Havenwood Stockholders resulting or arising from any of the following
("Havenwood Indemnified Claims"):

          (i)  Any inaccuracy in any of the representations and warranties made
               by IWC herein or in any exhibit or schedule attached hereto or
               any facts or circumstances constituting such inaccuracy; and

          (ii) Any breach or nonfulfillment by IWC of the covenants or
               agreements set forth herein or in any exhibit or schedule
               attached hereto or any facts or circumstances constituting such
               breach or nonfulfillment;

provided, however, that Havenwood Stockholders shall, in the event of a claim
for such indemnification, be entitled to reimbursement for Losses in connection
with such claim only as provided herein.

     (c) As used herein, "Loss" or "Losses" shall mean any damage, liability or
loss (including, without limitation, reasonable attorneys' fees and court costs
and reasonable costs and expenses incident to, and amounts paid by the IWC
Stockholders or Havenwood (after the Merger), or any of their respective
affiliates, in settlement of, any claim, suit, action or proceeding) sustained,
incurred, paid or required to be paid by the IWC Stockholders or Havenwood
(after the Merger), or any of their respective affiliates, after the date
hereof, plus interest thereon at an annual rate of interest equal to the prime
rate of interest of Texas Commerce Bank National Association from the date of
such Loss to the date such claim is paid, provided that losses shall not be
duplicative (with respect to the IWC Stockholders and Havenwood (after the
Merger)) and shall be paid to the party or parties incurring such loss.

     (d) The period of indemnity for Losses (the "Indemnity Period") shall begin
on the date hereof and end at midnight on the second anniversary of the
Effective Time, and upon such expiration, the Indemnitors shall have no further
liability in respect of IWC Indemnified Claims and IWC shall have no further
liability for Havenwood Indemnified Claims hereunder; provided, however, that if
there is an outstanding notice of claim at the expiration of the Indemnity
Period, the Indemnity Period shall continue until each such indemnified claim or
claim related to such claimed Loss is resolved.  The Indemnity Period shall not
continue as a result of the mere sending of a general notice of a claim
unsupported by a reasonable basis for believing that grounds for indemnification
exist; provided that the party receiving a notice which it believes meets the
exception set forth in the preceding clause shall raise such objection within
five days of receipt thereof and the party sending such notice shall have five
days thereafter to amend such notice to identify the reasonable basis of such
claim.

     (e) Notwithstanding anything to the contrary contained herein, IWC
Stockholders and Havenwood (after the Merger) shall not be permitted
indemnification for any IWC Indemnified Claim until the Losses incurred with
respect to all IWC Indemnified Claims aggregate $20,000, in which event IWC
Stockholders shall be indemnified for the full value of all such IWC Indemnified
Claims and the full value of all subsequent IWC Indemnified Claims for which,
individually, Losses in excess of $1,000 have been incurred or asserted.
<PAGE>
 
     (f) Notwithstanding anything to the contrary contained herein, Havenwood
Stockholders shall not be permitted indemnification for any Havenwood
Indemnified Claim until the Losses incurred with respect to all Havenwood
Indemnified Claims aggregate $50,000, in which event Havenwood Stockholders
shall be indemnified for the full value of all such Havenwood Indemnified Claims
and the full value of all subsequent Havenwood Indemnified Claims for which,
individually, Losses in excess of $1,000 have been incurred or asserted.

     (g) Indemnification for a Havenwood Indemnified Claim shall be solely in
the form of issuance of additional shares of Havenwood Common to Havenwood
Stockholders (their successors, assigns and transferees) pro rata in accordance
with their ownership of Havenwood Stock equal to the aggregate amount of the
Loss associated with such Havenwood Indemnified Claim through the date of
issuance.  The value of such Havenwood Common for the purposes of this Section
4.03 only in determining the number of shares to be issued to compensate
Havenwood Stockholders for such Havenwood Indemnified Claim shall be fixed at
the fair market value per share determined by reference to the average closing
bid price of the thirty (30) day period immediately preceeding the date payment
is due hereunder.  No payment shall be required of the recipients of shares of
Havenwood Common issued pursuant to this Section 4.03 in respect to such shares,
and Havenwood shall provide for the transfer of funds from its surplus account
to its stated capital account as necessary in relation to the aggregate par
value of the shares so issued.

     (h) A claim for indemnification hereunder shall be sent to Havenwood and
each other Representative (as defined in subsection (i) hereof) by registered or
certified mail prior to the expiration of the Indemnity Period and shall set
forth (i) a brief description of the nature of the potential or actual Loss, and
(ii) the total amount of the Loss anticipated or incurred.  Upon receiving
notice, if the Representative receiving the notice rejects any Loss, such
Representative shall give written notice of such rejection within thirty days
after the date of the notice of claim.  If no such rejection of a notice of a
claim shall be so sent within such 30-day period, Havenwood and the
Representative receiving notice of a claim for any Loss shall be deemed to
acknowledge the validity of such claim for the full amount thereof.  Each
Representative shall endeavor to assert each claim for indemnification, if any,
promptly after it has actual notice of such claim, even if it has not determined
the full amount of Loss associated with such claim.  In the event that the other
Representative shall have made timely rejection of any such claim, and the
parties shall have failed to resolve or compromise such claim within thirty days
from the date the receiving Representative shall have mailed notice of such
rejection, then such claim shall be settled by arbitration in Houston, Harris
County, Texas.  Such arbitration shall be subject to the Texas General
Arbitration Act and the rules of the American Arbitration Association, in
accordance with this Section.  After the initiation of arbitration, the parties
shall attempt to agree upon one arbitrator.  In the absence of such agreement,
there shall be three arbitrators, one designated in writing by the
Representative sending the notice and one designated in writing by the
Representative receiving notice, both of which shall be designated within thirty
days after arbitration has been initiated.  The third arbitrator shall be chosen
by the two designated arbitrators within forty days after arbitration has been
initiated.  All expenses of the arbitration shall be borne by the parties to the
arbitration as the arbitrator(s) shall determine.  Any award shall be a
conclusive determination of the matter, shall be binding upon the parties and
shall not be contested by them.  Within ten days after the liability for
indemnity hereunder is finally established, whether by the agreement
(constructive or otherwise) with a notice of claim,
<PAGE>
 
settlement, arbitration or otherwise, payment shall be made in the amount of the
Loss determined by the arbitrator(s) in accordance with the terms hereof.

          (i)  Charles T. Phillips is hereby appointed to act as the agent and
attorney-in-fact of the IWC Stockholders and Havenwood (after the Merger), in
connection with the performance of this Section 4.03, and Mark Leibovit is
hereby appointed to act as the agent and attorney-in-fact of Havenwood
Stockholders in connection with the performance of this Section 4.03

of whom shall have authority including, but not limited to, executing and
delivering for and on behalf of such parties all notices, receipts, approvals,
consents, waivers, agreements, papers, instruments and other documents in
connection herewith which such Representative deems necessary or appropriate,
including, without limitation, in connection with any amendments to or waiver of
any of the terms or provisions hereof, the granting of any consent hereunder,
and in all other instances where the IWC Stockholders, Havenwood (after the
Merger) or the Havenwood Stockholders, as appropriate, are required or permitted
to take any action hereunder. Any instruments and other deliveries to be made or
delivered to any IWC Stockholders, Havenwood (after the Merger) or Havenwood
Stockholders pursuant to this Agreement may be made or delivered to or as
directed by the Representative of such parties, and upon any such payment or
delivery the other parties hereto shall have no further liability with respect
thereto. The IWC Stockholders, and Havenwood (after the Merger) may, by the vote
or consent of the holders of Havenwood Stock and Havenwood Warrants receiving a
majority of the Merger Consideration to be paid to IWC Stockholders hereunder,
from time to time designate another person to serve as their Representative, and
upon notice to the other parties hereto, such parties shall thereafter deal with
such successor as if he were the Representative named herein. Havenwood
Stockholders may, by the vote or consent of the holders of Havenwood Stock on
the date hereof, from time to time designate another person to serve as their
Representative, and upon notice to the other parties, such parties shall
thereafter deal with such successor as if he were the Representative named
herein. The appointment of each Representative or successor Representative shall
be coupled with an interest and shall be irrevocable and binding in all respects
upon each of the IWC Stockholders, Havenwood (after the Merger) and Havenwood
Stockholders and his, her or its respective successors, assigns, heirs and
personal representatives.

the board of directors of Havenwood has, in accordance with the Certificate of
Incorporation and By-laws of Havenwood and the General Corporation Law of

merger or the transactions herein contemplated.

for reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.
<PAGE>
 
          SECTION 5.05.  Severability.  If any term or other provision of this
Agreement is determined to be invalid, illegal or incapable of being enforced by
any rule of law or public policy, all other conditions and provisions of this
Agreement shall nevertheless remain in full force and effect so long as the
economic or legal substance of the transactions contemplated herein is not
affected in any manner materially adverse to any party.  Upon such determination
that any term or other provision is invalid, illegal or incapable of being
enforced, the parties hereto shall negotiate in good faith to modify this
Agreement so as to effect the original intent of the parties as closely as
possible in an acceptable manner to the end that the transactions contemplated
hereby are fulfilled to the extent possible.

          SECTION 5.06.  Entire Agreement.  This Agreement (together with the
Annexes, Schedules and Exhibits hereto) constitutes the entire agreement of the
parties and supersedes all prior agreements and undertakings, both written and
oral, between the parties with respect to the subject matter hereof.

          SECTION 5.07.  Assignment.  This Agreement shall not be assigned by

intended to or shall confer upon any other person any right, benefit or remedy
of any nature whatsoever under or by reason of this Agreement.

          SECTION 5.09.  Failure or Indulgence Not Waiver; Remedies Cumulative.
No failure or delay on the part of any party hereto in the exercise of any right
hereunder shall impair such right or be construed to be a waiver of, or
acquiescence in, any breach of any representation, warranty or agreement herein,
nor shall any single or partial exercise of any such right preclude other or
further exercise thereof or of any other right.  All rights and remedies
existing under this Agreement are in addition to, and not exclusive of, any
rights or remedies otherwise available.

          SECTION 5.10.  Governing Law.  It is the intention of the parties that
the internal laws, and not the laws of conflicts, of the State of Texas shall
govern the enforceability and validity of this Agreement, the construction of
its terms and the interpretation of the rights and duties of the parties;
provided, however, that with respect to matters of law concerning the internal
affairs of any entity that is a party to or the subject of this Agreement, the
law of the jurisdiction of organization of such entity shall govern.

          SECTION 5.11.  Jurisdiction.  Each party hereby irrevocably submits to
the exclusive jurisdiction of the United States District Court for the Southern
District of Texas or any court of the State of Texas located in the City of
Houston in any action, suit or proceeding arising in connection with this
Agreement or the transactions contemplated herein, and agrees that any such
action, suit or proceeding shall be brought only in such court (and waives any
objection based on forum non conveniens or any other objection to venue
therein); provided, however, that such consent to jurisdiction is solely for the
purpose referred to in this Section 5.11 and shall not be deemed to be a general
submission to the jurisdiction of said Courts or in the State of Texas other
than for such purpose.  All parties hereby waive any right to a trial by jury in
connection
<PAGE>
 
with any such action, suit or proceeding; provided, however, that matters to be
resolved through arbitration as specified herein shall be resolved only by such
arbitration, and the final arbitration award may thereafter be enforced as
provided in this Section 5.11.

          SECTION 5.12.  Counterparts.  This Agreement may be executed in one or
more counterparts, and by the different parties hereto in separate counterparts,
each of which when executed  shall be deemed to be an original but all of which
taken together shall constitute one and the same agreement.

          SECTION 5.13  Amendment.  This Agreement may be amended only by
written instrument executed by the parties hereto.

          IN WITNESS WHEREOF, Havenwood, Newco, IWC, Leibovit and Slatkin have
caused this Agreement to be executed as of the date first written above by their
respective officer thereunto duly authorized.
