subsidiary of Parent ("Sub"),  Aduddell Roofing & Sheet Metal, Inc., an Oklahoma
corporation (the "Company"), and Tim Aduddell, an Oklahoma resident and the sole
shareholder of the Company ("Shareholder").

     Whereas  Parent and  Company  wish to effect  Parent's  acquisition  of the
Roofing  Business of the Company  through a merger of the Company  with Sub (the
"Merger") on the terms and conditions set forth herein;

     Whereas the Board of Directors of the Company has approved a  Restructuring
Agreement  in the form of Annex A attached  hereto  with such  changes as may be
permitted  under  Section 6.13 (the  "Restructuring  Agreement"),  which will be
entered into before the Effective Time (as defined in Section 1.03), pursuant to
which,  before the Effective  Time, (a) all the assets of the Company  primarily
related to the Ranching  Operations (as defined in the Restructuring  Agreement)
will be transferred to Aduddell Holdings,  Inc., a newly-formed and wholly owned
subsidiary  of the  Company  ("Newco")  and (b) Newco will  assume  the  Assumed
Liabilities (as defined in the Restructuring Agreement);

     Whereas,  upon the  Split-Off (as defined  below),  it is intended that the
Company will own only the Roofing Business;

     Whereas,  upon the terms and  subject to the  conditions  set forth in this
Agreement,  at the Effective  Time,  the holder of shares of common  stock,  par
value $1.00 per share,  of the Company  ("Company  Common Stock") will receive a
distribution  of all the shares of common stock,  par value $.001 per share,  of
Newco ("Newco Common Stock") in consideration for the redemption of a portion of
their shares of Company Common Stock (the "Split-Off");

     Whereas,  upon the terms and  subject to the  conditions  set forth in this
Agreement,  at the Effective  Time, Sub will merge with and into the Company and
each issued and  outstanding  share of Company Common Stock,  other than Company
Common  Stock owned by Parent,  Sub or the Company,  will be converted  into the
right to  receive  (a) shares of common  stock,  par value  $.001 per share,  of
Parent ("Parent  Common Stock"),  (b) options to acquire shares of Parent Common
Stock, and (c) shares of Newco Common Stock;

     Whereas,  the respective Boards of Directors of Parent, Sub and the Company
have  approved  and  declared  advisable  this  Agreement  and the  transactions
contemplated hereby, and the sole shareholder of Sub has approved this Agreement
and the transactions contemplated hereby;

     Whereas,  simultaneously  with the execution and delivery of this Agreement
and as a condition  and  inducement to Parent's  willingness  to enter into this
Agreement,  certain Company executives have entered into separate employment and
non-competition  agreements  with  Parent  (collectively,  the  "Non-Competition
Agreements");

                                       1


     Whereas, for Federal income tax purposes, it is intended (a) by the Company
that the  distribution of Newco Common Stock in connection with the transactions
contemplated  by this Agreement  shall qualify,  as to the  shareholders  of the
Company, as a transaction  described in Section 355 of the Internal Revenue Code
of 1986,  as amended  (the  "Code")  (it being  understood  and agreed that such
qualification  shall not be a condition to the  consummation of the transactions
contemplated  by this  Agreement or the other  Transaction  Agreements  and that
Parent shall have no  obligation to cause such  distribution  to so qualify) and
(b) by the  parties  that (i) the Merger  shall  qualify  as a  "reorganization"
within the meaning of Section  368(a) of the Code,  as amended  (the "Code") and
(ii) this Agreement constitutes a plan of reorganization; and

     Whereas Parent, Sub and the Company desire to make certain representations,
warranties,  covenants and agreements in connection  with the Merger and also to
prescribe various conditions to the Split-Off and the Merger.

     Now,  Therefore,  in  consideration  of  the  representations,  warranties,
covenants and agreements  contained in this Agreement,  the parties hereto agree

delivery by the Company of each  Transaction  Agreement and the  consummation by
the Company of the transactions  contemplated  thereby have been duly authorized
by all  necessary  corporate  action  on the  part of the  Company  and no other
corporate proceedings on the part of the Company are necessary to authorize such
Transaction  Agreements or to consummate the transactions  contemplated thereby.
The execution and delivery by Newco of the Transaction Agreements to which it is

due  authorization,  execution and delivery by each of the other parties hereto,
constitutes a legal,  valid and binding  obligation of the Company,  enforceable
against the Company in accordance  with its terms.  Each  Transaction  Agreement
(other than this  Agreement) to which the Company or Newco will be a party will,
when executed and delivered by such entity, and, assuming the due authorization,
execution  and  delivery  by  Parent,  constitute  a legal,  valid  and  binding
obligation of such entity,  enforceable  against such entity in accordance  with
its  terms.  The Board of  Directors  of the  Company  has duly and  unanimously
adopted  resolutions  (i) approving and declaring  advisable  this Agreement and

                                       6

Transaction  Agreement to which it is a party and  consummate  the  transactions
contemplated  thereby  on the  terms and  subject  to the  conditions  set forth
therein, (iv) directing that this Agreement be submitted for the written consent
of the  Shareholder  and  (v)  recommending  that  the  Shareholder  adopt  this
Agreement.  The  execution  and  delivery  by the  Company  of  the  Transaction
Agreements do not, and the consummation of the transactions contemplated thereby
and compliance with the provisions thereof will not, conflict with, or result in
any violation or breach of, or default (with or without notice or lapse of time,
or  both)  under,  or give  rise  to a right  of  termination,  cancellation  or
acceleration  of any obligation or to loss of a benefit under,  or result in the
creation of any Lien in or upon any of the  properties  or assets of the Company
under,  (x) the Company  Certificate or Company  Bylaws,  (y) any loan or credit
agreement, bond, debenture, note, mortgage,  indenture, lease or other contract,
agreement,  obligation,  commitment,  arrangement,  understanding,   instrument,
permit or license, whether oral or written (excluding any such items between the
Company,  on the one hand,  and  Parent or any of its  Affiliates,  on the other
hand) (each,  including all  amendments  thereto,  a  "Contract"),  to which the
Company is a party or any of its  properties  or other  assets is subject or (z)
subject  to the  governmental  filings  and  other  matters  referred  to in the

applicable to the Company or its properties or other assets,  other than, in the
case of clauses (y) and (z), any such conflicts, violations, breaches, defaults,
rights,  losses or Liens that  individually or in the aggregate have not had and
are not reasonably expected to have a Material Adverse Effect.

     No consent,  approval,  order or authorization  of, action by or in respect
of, or registration,  declaration or filing with, any Federal,  state,  local or
foreign government, any court, administrative,  regulatory or other governmental
agency, commission or authority or any non-governmental  self-regulatory agency,
commission or authority  (each, a "Governmental  Entity") is required by or with
respect to the Company in  connection  with the  execution  and delivery of this
Agreement by the Company or the execution and delivery of the other  Transaction
Agreements by the Company or the consummation of the  transactions  contemplated

     (e)  Compliance  With Law. The Company is in compliance  with all statutes,
laws,  ordinances,  rules,  regulations,  judgments,  orders and  decrees of any
Governmental  Entity  applicable  to it, its  properties  or other assets or its

of noncompliance or possible noncompliance that individually or in the aggregate
have not had and are not reasonably  expected to have a Material Adverse Effect.
The Company has in effect all material approvals, authorizations,  certificates,

                                       7


properties  and assets and to carry on its business and  operations as presently
conducted,  except for failures to have in effect such Permits that individually
or in the  aggregate  have  not had and are not  reasonably  expected  to have a
Material  Adverse Effect.  There has occurred no default under, or violation of,
any such Permit,  except individually or in the aggregate as has not had and are
not reasonably  expected to have a Material  Adverse Effect.  The Merger and the
other  transactions  contemplated  by  the  Transaction  Agreements,  in  and of
themselves,  will not cause the  revocation or  cancellation  of any Permit that
individually  or in the  aggregate  are  reasonably  expected to have a Material
Adverse  Effect.  No  action,  demand,   requirement  or  investigation  by  any
Governmental  Entity and no suit,  action or proceeding by any other person,  in
each case with respect to the Company or any of its  properties  or other assets
under any Legal  Provision,  is pending or, to the  Knowledge of the Company and
the  Shareholder,  threatened,  other than,  in each case,  those the outcome of

expected to have a Material Adverse Effect.

Company and the Shareholder,  threatened against or affecting the Company or any

reasonably  expected  to  have a  Material  Adverse  Effect,  nor is  there  any
judgment,  decree,  injunction,  rule or order  of any  Governmental  Entity  or
arbitrator  outstanding  against,  or, to the  Knowledge  of the Company and the
Shareholder,  investigation by any Governmental  Entity  involving,  the Company
that individually or in the aggregate has had or are reasonably expected to have
a Material Adverse Effect.

audited  balance  sheets,  statements of operations and statements of cash flows
for the years  ended  December  31,  2000 and 2001,  and the  unaudited  balance
sheets,  statement of operations  and statement of cash flows for the six months
ended June 30, 2002 (the  "Balance  Sheet  Date").  Each of the  balance  sheets
(including  any related  notes and  schedules)  fairly  presents in all material
respects the financial  position of the Company as of its date,  and each of the
statements of operations  and  statements of cash flows  (including  any related
notes and  schedules)  fairly  presents in all material  respects the results of
operations  and cash  flows,  as the case may be, of the Company for the periods
set forth  therein  (subject in the case of unaudited  statements to normal year
end  adjustments)  (i) in the  case  of the  audited  financial  statements,  in
accordance with generally accepted  accounting  principles ("GAAP") applied on a
consistent basis, and (ii) in the case of the unaudited financial statements, in
accordance  with GAAP (except the  required  footnote  disclosures).  All of the
adjustments  necessary to convert in all material respects the audited financial
statements into GAAP have been recorded in the appropriate  periods on the books
and records of the Company,  and after the  application of such  adjustments all
the  financial  statements  referred to in this Section have been  prepared on a
consistent basis. There has been no material change in the financial position of
the Company  since the Balance  Sheet Date.  Except  disclosed in the  financial
statements or the footnotes  thereto and except for  liabilities  or obligations
incurred  in  connection  with this  Agreement  or any of the other  Transaction
Agreements,  the Company has no liabilities or obligations (other than to Parent
or any of its Affiliates) of any nature (whether accrued,  absolute,  contingent
or  otherwise)  which,  individually  or in  the  aggregate,  have  had  or  are
reasonably expected to have a Material Adverse Effect.

other Tax  Returns or  extension  requests  for all fiscal  periods  ended on or
before the Balance Sheet Date;  and except as set forth in disclosure  schedule,
there are no  examinations in progress or claims pending against the Company for
federal, state and other Taxes (including penalties and interest) for any period
or periods  before and  including  the  Balance  Sheet Date and no notice of any
claim for Taxes,  whether  pending or threatened,  has been  received.  All Tax,

provisions of ERISA and the regulations issued  thereunder,  as well as with all
other applicable federal, state and local statutes, ordinances and regulations.

          Sheet Date with  respect to any plan listed in Schedule  4.01(q)  have

          Schedule 4.01(r);

     (iv) the Company  (including any subsidiaries)  has not incurred  liability
          under Section 4062 of ERISA; and

     (v)  no  circumstances  exist  pursuant to which the Company could have any
          direct or indirect liability  whatsoever  (including,  but not limited
          to, any liability to any multiemployer plan or the PBGC under Title IV
          of ERISA or to the IRS for any excise tax or penalty, or being subject
          to any statutory  Lien to secure payment of any such  liability)  with
          respect to any plan now or heretofore  maintained or contributed to by
          any  entity  other  than the  Company  that is, or at any time was,  a
          member of a "controlled group" (as defined in Section  412(n)(6)(B) of
          the Code) that includes the Company.

execution of this Agreement (the "Parent Disclosure  Schedule"),  Parent and Sub
represent and warrant to the Company as follows:

corporation duly organized, validly existing and in good standing under the laws
of the jurisdiction in which it is incorporated and has all requisite  corporate
power and  authority  to carry on its business as now being  conducted.  Each of
Parent and Sub is duly  qualified  or  licensed  to do  business  and is in good
standing  in each  jurisdiction  in which  the  nature  of its  business  or the
ownership,  leasing or operation of its properties  makes such  qualification or
licensing necessary, other than in such jurisdictions where the failure to be so
qualified or licensed  individually  or in the  aggregate has not had and is not
reasonably  expected to have a Parent Material  Adverse Effect.  Parent has made
available to the Company complete and correct copies of its Restated Certificate
of Incorporation  and Bylaws and the Certificate of Incorporation  and Bylaws of
Sub, in each case as amended to the date hereof.

     (b) Authority;  Noncontravention.  Each of Parent and Sub has the requisite
power and authority to enter into each  Transaction  Agreement to which it is or

execution and delivery of each Transaction Agreement to which it is or will be a
party and the  consummation of the transactions  contemplated  thereby have been
duly authorized by all necessary  corporate action on the part of Parent and Sub
and no other corporate proceedings on the part of Parent or Sub are necessary to
authorize  any such  Transaction  Agreement or to  consummate  the  transactions
contemplated thereby. All outstanding shares of Parent Common Stock are, and all
shares of Parent  Common  Stock which may be issued  pursuant to this  Agreement
shall  when  issued  be,  duly  authorized,   validly  issued,  fully  paid  and
nonassessable and not subject to preemptive rights. This Agreement has been duly
executed and delivered by Parent and Sub, and,  assuming the due  authorization,
execution and delivery by the Company,  constitutes  a legal,  valid and binding
obligation of Parent and Sub,  enforceable against Parent and Sub, in accordance
with its terms. Each Transaction  Agreement (other than this Agreement) to which
Parent  will be a party  will,  when  executed  and  delivered  by Parent,  and,
assuming  the due  authorization,  execution  and  delivery by each of the other
parties  thereto,  constitute a legal,  valid and binding  obligation of Parent,
enforceable  against such entity in accordance with its terms. The execution and
delivery  by Parent of each  Transaction  Agreement  to which it is a party does
not, and the consummation of the Merger and the other transactions  contemplated
thereby and compliance with the provisions  thereof will not,  conflict with, or
result in any  violation  or breach  of, or default  (with or without  notice or

                                       16


lapse  of  time,  or  both)  under,  or give  rise to a  right  of  termination,
cancellation or acceleration of any obligation or to loss of a benefit under, or
result  in the  creation  of any Lien  upon any of the  properties  or assets of
Parent or Sub under (i) the Restated  Certificate of  Incorporation or Bylaws of
Parent or the Certificate of  Incorporation  or Bylaws of Sub, (ii) any Contract
to which  Parent or Sub is a party or any of its  properties  or other assets is
subject or (iii) subject to the governmental  filings and other matters referred
to in  the  following  sentence,  any  (A)  statute,  law,  ordinance,  rule  or
regulation or (B) order, writ, injunction,  decree, judgment or stipulation,  in
each case  applicable to Parent or Sub or their  respective  properties or other
assets,  other than, in the case of clauses (ii) and (iii),  any such conflicts,
violations,  breaches, defaults, rights, losses or Liens that individually or in
the  aggregate  have not had and are not  reasonably  expected  to have a Parent
Material Adverse Effect. No consent, approval, order or authorization of, action
by or  in  respect  of,  or  registration,  declaration  or  filings  with,  any
Governmental  Entity  is  required  by or  with  respect  to  Parent  or  Sub in
connection  with the  execution  and  delivery  of this  Agreement  or the other
Transaction  Agreements by Parent and Sub or the  consummation by Parent and Sub
of the Merger or the other transactions  contemplated hereby or thereby,  except
for (1)  such  reports  under  Section  13(a),  13(d),  15(d)  or  16(a)  of the
Securities  Exchange  Act of 1934 (the  "Exchange  Act") as may be  required  in
connection  with  this  Agreement  and  the  transactions  contemplated  by this
Agreement,  (2) the filing of the  Certificate  of Merger with the  Secretary of
State of the State of Oklahoma, and (3) such other consents,  approvals, orders,
authorizations,  registrations, declarations and filings the failure of which to
be obtained or made,  individually or in the aggregate,  has not had and are not
reasonably expected to have a Parent Material Adverse Effect.

     (c)  Information  Supplied.  None  of  the  information  supplied  or to be
supplied  by  Parent or Sub  specifically  for  inclusion  or  incorporation  by
reference  in the  Parent  Form 8-K will,  at the time it is filed with the SEC,
contain any untrue  statement  of a material  fact or omit to state any material
fact required to be stated therein or necessary to make the statements  therein,
in light of the circumstances under which they are made, not misleading,  except
that no  representation  or  warranty  is made by Parent or Sub with  respect to
statements  made or  incorporated  by  reference  therein  based on  information
supplied by the Company specifically for inclusion or incorporation by reference
in the Parent Form 8-K.

     (d) Interim  Operations  of Sub.  Sub was formed  solely for the purpose of
engaging  in the  transactions  contemplated  hereby,  has  engaged  in no other
business  activities  and has  conducted  its  operations  only as  contemplated
hereby.

     (e) Tax Matters.  Neither Parent, Sub nor any Affiliate of Parent has taken
or  agreed  to take any  action  or knows  of any fact or  circumstance  that is
reasonably  likely to prevent the Merger  from  qualifying  as a  reorganization
within the meaning of Section 368(a) of the Code.

     (f)  Parent  Shareholder  Approval.  This  Agreement  and the  transactions
contemplated  hereby,  including  the issuance of shares of Parent  Common Stock
pursuant to Article II hereof, do not require the approval of the holders of any
shares of capital stock of Parent.

                                       17


     (g) Opinions of Financial Advisor. Parent's Board of Directors has received
the opinion of Benchmark  Global Capital  Group,  Inc. to the effect that, as of
the date thereof,  the Merger  Consideration  is fair from a financial  point of
view to the holders of shares of Parent Common Stock.

     (h)  Brokers.  No broker,  investment  banker,  financial  advisor or other
person is entitled  to any  broker's,  finder's,  financial  advisor's  or other
similar fee or commission in connection  with the  transactions  contemplated by
this Agreement.

any of its  representations,  warranties,  covenants or agreements  set forth in
this Agreement.

     Section  9.03.  Amendment.  This  Agreement  may be amended by the  parties
hereto at any time before or after any Shareholder  Approval with, if necessary,

signed on behalf of each of the parties hereto.

party to this  Agreement  to assert any of its rights  under this  Agreement  or
otherwise shall not constitute a waiver of such rights.

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 to the fullest
extent  permitted by applicable law in an acceptable  manner to the end that the
transactions contemplated hereby are fulfilled to the extent possible.

                            FORM OF AFFILIATE LETTER

Dear Sirs:

     The  undersigned,  the  holder of all of the  outstanding  shares of common
stock, par value $1.00 per share ("Company Common Stock"), of Aduddell Roofing &
Sheet Metal, Inc., an Oklahoma corporation (the "Company"), acknowledges that he
will be deemed an  "affiliate"  of the  Company  within the  meaning of Rule 145
("Rule  145")  promulgated  under the  Securities  Act of 1933,  as amended (the
"Securities  Act"),  by the  Securities  and  Exchange  Commission  (the "SEC").
Pursuant to the terms of the  Agreement and Plan of Merger dated as of September
27, 2002, among Zenex International, Inc., a Colorado corporation ("Parent"), AR
Acquisition  Corp.,  an Oklahoma  corporation  and a wholly owned  subsidiary of
Parent  ("Sub"),  and the Company,  Sub will be merged with and into the Company
(the "Merger"),  and in connection with the Merger,  the undersigned is entitled
to receive common stock,  par value $.001 per share ("Parent Common Stock"),  of
Parent.

     As an affiliate  under the  Securities  Act, the  undersigned's  ability to
sell,  assign or transfer the Parent Common Stock received by the undersigned in
exchange for any shares of Company  Common Stock in  connection  with the Merger
will be restricted  unless such  transaction is registered  under the Securities
Act or an  exemption  from  such  registration  is  available.  The  undersigned
understands  that such exemptions are limited and he has obtained or will obtain
advice of counsel as to the nature and conditions of such exemptions,  including
information with respect to the  applicability to the sale of such securities of
Rules 144 and 145(d) promulgated under the Securities Act.

     The  undersigned  hereby  represents to and covenants  with Parent that the
undersigned  will not sell,  assign or transfer  any of the Parent  Common Stock
received by the  undersigned  in exchange for shares of Company  Common Stock in
connection  with the Merger  except (i)  pursuant to an  effective  registration
statement under the Securities Act, (ii) in conformity with the volume and other
limitations,  if applicable, of Rule 145 or (iii) in a transaction which, in the
opinion of counsel to Parent or the undersigned or as described in a "no-action"
or  interpretive  letter  from the  Staff of the SEC  specifically  issued  with
respect to a transaction to be engaged in by the undersigned, is not required to
be registered under the Securities Act.

     Parent  covenants  that it will take all such actions as may be  reasonably
available to it to permit the sale or other  disposition  of Parent Common Stock
by the undersigned under Rule 145 in accordance with the terms thereof.

     The  undersigned  acknowledges  and agrees that the legends set forth below
will be placed on certificates  representing Parent Common Stock received by the
undersigned in connection with the Merger or held by a transferee thereof, which
legends will be removed by delivery of substitute  certificates  upon receipt of
an opinion in form and substance reasonably  satisfactory to Parent from counsel
reasonably  satisfactory to Parent to the effect that such legends are no longer
required for purposes of the Securities Act.

                                       34


     There will be placed on the  certificates for Parent Common Stock issued to
the undersigned in connection with the Merger, or any substitutions  therefor, a
legend stating in substance:

     "The shares represented by this certificate were issued in a transaction to
     which Rule 145  promulgated  under the Securities Act of 1933 applies.  The
     shares  have not been  acquired by the holder with a view to, or for resale
     in connection  with,  any  distribution  thereof  within the meaning of the
     Securities  Act of 1933.  The shares may not be sold,  pledged or otherwise
     transferred  except in accordance  with an exemption from the  registration
     requirements of the Securities Act of 1933."

     The  undersigned  acknowledges  that (i) the undersigned has carefully read
this letter and understands the requirements  hereof and the limitations imposed
upon the  distribution,  sale,  transfer or other  disposition  of Parent Common
Stock and (ii) the receipt by Parent of this letter is an inducement to Parent's
obligations to consummate the Merger.


Dated:                                                  Very truly yours,

                                                        /s/ Tim Aduddell

ANNEX A

                             RESTRUCTURING AGREEMENT

     This  Restructuring  Agreement,   dated  as  of  September  27,  2002  (the
"Restructuring  Agreement"),  among  Aduddell  Roofing & Sheet Metal,  Inc.,  an
Oklahoma corporation (the "Company"),  and Aduddell Holdings,  Inc., an Oklahoma
corporation and a direct wholly owned subsidiary of the Company ("Newco").

     Whereas,  the Company,  Zenex  International,  Inc., a Colorado Corporation
("Parent"), and AR Acquisition Corp., an Oklahoma corporation and a wholly owned
subsidiary  of  Parent  ("Sub"),  have  entered  into an  Agreement  and Plan of
Split-Off and Merger,  dated as of September 27, 2002 (the "Merger  Agreement"),
providing  for the  Split-Off  and the  Merger  (each as  defined  in the Merger
Agreement)  of Sub with and into the Company,  with the Company as the surviving
corporation;

     Whereas the  respective  Boards of  Directors of the Company and Newco have
approved this  Restructuring  Agreement,  which is being entered into before the
Effective  Time (as  defined in the  Merger  Agreement),  pursuant  to which the
Restructuring (as defined below) will be consummated;

     Whereas the purpose of the  Restructuring is to make possible the Split-Off
and the Merger by  separating  from the Assets and  Liabilities  of the  Company
those Assets and Liabilities that Parent will not acquire;

     Whereas  in the  Restructuring,  all the  Assets  primarily  related to the
Ranching Operations and such other Assets specifically identified (collectively,
the "Newco  Business")  will be  transferred  to Newco,  which  will  thereafter
conduct such business, and Newco will assume the Assumed Liabilities (as defined
below); and

     Whereas it is the intention of the parties to this Restructuring  Agreement
that the  transfer  of Assets and  Liabilities  pursuant  to this  Restructuring
Agreement shall qualify as a transaction described in Section 351 or Section 368
of the Code.

     Now,  Therefore in  consideration  of the premises,  and of the  respective
representations,  warranties,  covenants and  agreements  set forth herein,  the

Company's  right,  title and  interest in and to (i) all Assets that are used or
held for use primarily in the operation or conduct of the Newco Business  (other
than those set forth on Schedule  3.2)),  and (ii) all Assets that are set forth
on Schedule 3.1 (collectively,  the "Newco Assets").  Such contribution shall be
referred to as the "Restructuring".

     3.2 Assets Not  Transferred.  Notwithstanding  anything to the contrary set
forth in Section  3.1, the Company  hereby  retains and does not  contribute  to
Newco any of the Company's  right,  title and interest in and to all Assets that

Newco Business (other than those set forth on Schedule 3.1) or (y) are set forth
on Schedule 3.2 hereto (collectively, the "Roofing Assets").

     3.3 Assumed  Liabilities.  Notwithstanding  Section 3.1, the parties  agree
that,  except as otherwise  specifically set forth in any Transaction  Agreement
(including  the  treatment  of Tax  Liabilities  as set forth in Section  2.2 or
employee  related  Liabilities  as set forth in Section  6.2),  at or before the
Effective  Time,  (a) Newco shall  unconditionally  assume and undertake to pay,
satisfy and discharge (x) all Liabilities  (whether  arising before or after the
Restructuring)  of the Company to the extent primarily related to or arising out
of the Newco  Business  and (y) all  Liabilities  set forth on  Schedule  3.3(a)
hereto  (clauses  (x) and  (y)  are  collectively  referred  to as the  "Assumed
Liabilities"),  in  each  case  when  such  Assumed  Liabilities  become  due in
accordance with their terms,  and (b) the Company shall retain,  or shall assume
and undertake to pay, satisfy and discharge (x) all Liabilities (whether arising
before  or after  the  Restructuring)  of the  Company  other  than the  Assumed
Liabilities and (y) all Liabilities set forth on Schedule 3.3(b) hereto (clauses
(x) and (y) are collectively referred to as the "Aduddell Liabilities"), in each
case when such Aduddell Liabilities become due in accordance with their terms.

     3.4  Transfer  and   Assumption   Documentation.   In  furtherance  of  the
contribution, grant, conveyance, assignment, transfer and delivery of the Assets
and the  assumption  of the  Liabilities  set forth in this Article III, (i) the

deliver,  such  deeds,  bills of sale,  stock  powers,  certificates  of  title,
assignments  of leases and  contracts  and other  instruments  of  contribution,
grant, conveyance,  assignment, transfer and delivery necessary to evidence such
contribution, grant, conveyance,  assignment, transfer and delivery and (ii) the
transferee  shall execute and deliver such  instruments  of assumption as and to
the extent necessary to evidence such assumption.

     3.5  Nonassignable  Contracts.  Anything  contained  herein to the contrary
notwithstanding,  this Restructuring Agreement shall not constitute an agreement
to assign  any lease,  license  agreement,  contract,  agreement,  sales  order,

                                       40


purchase  order,  open bid or other  commitment  if an  assignment  or attempted
assignment of the same without the consent of the other party or parties thereto
would  constitute  a breach  thereof or in any way impair the rights of Newco or
Aduddell Roofing  thereunder.  All such items that are material are set forth on
Schedule  3.5.  The  Company  or  Newco,  as the  case  may  be,  shall  use its
commercially reasonable efforts (it being understood that such efforts shall not
include any requirement of Newco or Aduddell Roofing to expend money or offer or
grant any  financial  accommodation),  to obtain all consents and waivers and to
resolve all  impracticalities of assignments or transfers necessary to convey to
the other  party the Assets so to be conveyed  pursuant  to Section  3.1. If and

Asset  shall be  effected  in  accordance  with the terms of this  Restructuring
Agreement.

     3.6 Intercompany Arrangements. All agreements,  contracts, arrangements and
commitments  (other than the Transaction  Agreements)  between Newco, on the one
hand, and Aduddell Roofing (other than Newco),  on the other hand,  entered into
before the Effective Time and set forth on Schedule 3.6 for the purchase or sale
of  goods or  services  ("Intercompany  Arrangements")  shall  terminate  on the
Effective  Time.  All  amounts  under such  Intercompany  Arrangements  that are
unbilled and have not been charged to the related  contract as of the  Effective
Time  shall be billed  and  payable  on the  Effective  Time.  At or before  the
Closing,  the Company  shall cause all  intercompany  indebtedness  (which shall
include  payables and  receivables)  between Newco or any operating  unit of any
Newco Company,  on the one hand,  and Aduddell  Roofing or any operating unit of
any Aduddell  Company (other than Newco or any operating  unit thereof),  on the
other hand, including without limitation any indebtedness under the intercompany
arrangements set forth on Schedule 3.6, to be settled or otherwise eliminated.

                           ARTICLE IV OTHER AGREEMENTS

     4.1 Books and  Records.  Before or as  promptly  as  practicable  after the
Effective  Time,  the  Company  shall  deliver  to Newco all  books and  records
relating to the business of Newco in the  possession  of Aduddell  Roofing.  The
Company may retain copies of all such corporate books and records.  Before or as
promptly as  practicable  after the Effective  Time,  Newco shall deliver to the
Company all books and records relating to Aduddell Roofing, the Roofing Business
or the Aduddell Liabilities.

     4.2 Access.  From and after the  Effective  Time,  the Company,  on the one
hand, and Newco, on the other hand, shall afford to the other and to the other's
Representatives  reasonable  access and  duplicating  rights (at the  requesting
person's  expense),  during normal  business hours and upon  reasonable  advance
notice, to all information  within the possession or control of Aduddell Roofing
or Newco, as the case may be, to the extent  directly  relating to the business,
Assets or  Liabilities of the other as they existed before the completion of the
Restructuring  or to the extent  relating to or arising in  connection  with the
relationship  between  Aduddell Roofing or Newco, as the case may be, before the
Restructuring  insofar as such access is  reasonably  required  for a reasonable
purpose. Without limiting the foregoing, information may be requested under this
Section 4.2 for audit, accounting,  claims, litigation and tax purposes, as well
as for purposes of fulfilling disclosure and reporting obligations.

                                       41

receiving  party or its  Representatives  shall  promptly  notify the disclosing
party of the request in  writing,  and  consult  with and assist the  disclosing
party in seeking a protective order or request for other appropriate  remedy. In
the event that such  protective  order or other  remedy is not  obtained  or the
disclosing party waives  compliance with the terms hereof,  such receiving party
or its Representatives,  as the case may be, shall disclose only that portion of
the Information or facts which, in the written opinion of the receiving  party's
outside  counsel,  is legally  required to be  disclosed,  and will exercise its
respective commercially reasonable efforts to assure that confidential treatment
will be accorded such Information or facts by the Persons or entities  receiving
the same.  The  providing  party  will be given an  opportunity  to  review  the
Information or facts before disclosure.

     4.4 Further Assurances.  The parties agree that if, after the completion of
the Restructuring, either party holds Assets which by the terms hereof or of the
Merger  Agreement were intended to be assigned and  transferred  to, or retained
by, the other party,  such party  shall,  at its  expense,  promptly  assign and
transfer or cause to be assigned and transferred such Assets to the other party,
and the  parties  agree that the  transferring  party  will hold such  Assets as
trustee  of the  transferee  party  and  all  income  and  risk  of  loss of the
transferred  Assets  to the  completion  of the  Restructuring  shall be for the
account of the intended owner.  Each of the parties hereto,  at its own cost and
expense,  promptly shall execute such documents and other  instruments  and take
such further actions as may be reasonably required or desirable to carry out the
provisions hereof and to consummate the transactions contemplated hereby.

     4.5  Cooperation.  The  parties  shall  cooperate  with  each  other in all
reasonable  respects to ensure (a) that the  Restructuring and the assumption of
the  Aduddell  Liabilities  and  the  Assumed  Liabilities  are  consummated  in
accordance  with the terms  hereof,  (b) the  retention  by the  Company  of the
Roofing  Business,  including,  without  limitation,  allocation  of rights  and
obligations under Contracts, if any, of Aduddell Roofing or Newco that relate to
the  Roofing  Business,  (c) the  transfer  to  Newco of all the  Newco  Assets,
including,  without  limitation,  allocation  of rights  and  obligations  under

employment,  consulting,  deferred compensation,  indemnification,  termination,
severance or any other agreements with a Newco Employee or a Aduddell  Employee,
to which  Aduddell  Roofing or Newco  Companies  is a party,  as the same are in
effect  immediately  before such time,  any such agreement with a Newco Employee
shall be assumed by Newco, and that any such agreement with a Aduddell  Employee
shall be assumed by the  Company,  and in respect of which Newco or the Company,
as the  case  may  be,  becomes  solely  responsible  for  the  obligations  and
Liabilities (and solely entitled to the rights) under such agreements.

     5.4 No  Termination.  The Company and Newco shall take such  actions as are
required to provide that for purposes of severance benefits, each Newco Employee
shall be deemed not to have incurred a termination  of employment as a result of

ANNEX B

                             STOCK OPTION AGREEMENT

     This  Stock  Option   Agreement  dated  as  of  September  27,  2002  (this
"Agreement"),  by and between Zenex International,  Inc., a Colorado corporation
("Issuer"), and Tim Aduddell, an Oklahoma resident ("Shareholder").

                                    Recitals

     A. Issuer, Sub, the Company, and Shareholder have entered into an Agreement
and Plan of  Split-Off  and  Merger  dated as of the date  hereof  (the  "Merger
Agreement"),  providing for, among other things, the merger of Sub with and into
the Company and the delivery to the Shareholder of the Merger Consideration;

     B. Part of the  Merger  Consideration  is  composed  of the  Merger  Option
Consideration; and

     C. The  Merger  Option  Consideration  shall be  governed  by the terms and
conditions of this Agreement.

     Now,  Therefore,  in  consideration  of the  foregoing  and the  respective
representations,  warranties,  covenants and agreements set forth herein, Issuer
and Shareholder agree as follows:

     1.  Grant of Option.  Upon the  Effective  Time,  Issuer  hereby  grants to
Shareholder  an  irrevocable  option (the "Option") to purchase up to 30,000,000
shares of common  stock,  par value  $0.001 per share,  of Issuer  (the  "Issuer
Common Stock") (as such total number may be adjusted  pursuant to Section 6, the
"Option  Shares") at an exercise  price of $.04 per Option  Share (as such price
may be adjusted pursuant to Section 6, the "Exercise Price").

     2. Exercise of Option.

     (a) Subject to the provisions of Section 2(c), Shareholder may exercise the
Option,  with respect to any or all of the Option  Shares,  at any time or times
after six months following the Effective Time; provided,  however,  that (i) the
Option  will  terminate  and be of no  further  force  and  effect  on the tenth
anniversary of the Effective Time.

     (b) If  Shareholder  is  entitled  to and wishes to  exercise  the  Option,
Shareholder  shall send to Issuer a written  notice (an "Exercise  Notice";  the
date of which being  herein  referred to as the "Notice  Date") to that  effect,
which  Exercise  Notice  shall  specify  the  number of Option  Shares,  if any,
Shareholder  wishes to purchase pursuant to this Section 2(b), the denominations
of  the  certificate  or   certificates   evidencing  the  Option  Shares  which
Shareholder wishes to purchase,  and a date (an "Option Effective Time"), which,
subject to the following sentence, shall not be earlier than three business days
nor later than ten  business  days from the Notice  Date for the closing of such
purchase  (an  "Option  Closing").  Any  Option  Closing  shall be at an  agreed
location and time in Oklahoma City, Oklahoma, on the applicable Option Effective
Time.

                                       49


     (c) Notwithstanding anything to the contrary contained herein, any exercise
of the Option and purchase of Option Shares shall be subject to compliance  with
applicable  laws and  regulations,  which may  prohibit  the purchase of all the
Option Shares specified in the Exercise Notice without first obtaining or making
certain  Regulatory  Approvals.  In  such  event,  if the  Option  is  otherwise
exercisable  and  Shareholder  wishes to exercise the Option,  the Option may be
exercised in  accordance  with Section 2(b) and  Shareholder  shall  acquire the
maximum  number  of  Option  Shares   specified  in  the  Exercise  Notice  that
Shareholder  is  then  permitted  to  acquire  under  the  applicable  laws  and
regulations,  and if Shareholder  thereafter obtains the Regulatory Approvals to
acquire the  remaining  balance of the Option  Shares  specified in the Exercise
Notice,  then Shareholder  shall be entitled to acquire such remaining  balance.
Issuer agrees to use its commercially  reasonable  efforts to assist Shareholder
in seeking the Regulatory Approvals.

     3. Payment and Delivery of Certificates.

     (a) At any Option  Closing,  Shareholder  will pay to Issuer in immediately
available  funds by wire  transfer to a bank  account  designated  in writing by
Issuer an amount equal to the Exercise Price  multiplied by the number of Option
Shares to be purchased at such Option Closing.

     (b) At any Option Closing,  simultaneously with the delivery of immediately
available funds as provided in Section 3(a),  Issuer will deliver to Shareholder
a certificate or certificates  representing the Option Shares to be purchased at
such Option Closing, which Option Shares will be free and clear of all Liens.

     (c)  Certificates  representing  the Option  Shares  delivered at an Option
Closing will have typed or printed thereon a restrictive  legend which will read
substantially as follows:

     "THE SECURITIES  REPRESENTED BY THIS  CERTIFICATE  HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED,  AND MAY BE REOFFERED OR SOLD
     ONLY  IF SO  REGISTERED  OR IF  AN  EXEMPTION  FROM  SUCH  REGISTRATION  IS
     AVAILABLE.  SUCH SECURITIES ARE ALSO SUBJECT TO ADDITIONAL  RESTRICTIONS ON
     TRANSFER AS SET FORTH IN THE STOCK OPTION  AGREEMENT  DATED AS OF SEPTEMBER
     27,  2002,  A COPY OF WHICH MAY BE  OBTAINED  FROM THE  SECRETARY  OF ZENEX
     INTERNATIONAL, INC., AT ITS PRINCIPAL EXECUTIVE OFFICES."

     It is understood and agreed that (i) the reference to restrictions  arising
under the  Securities  Act in the above  legend  will be removed by  delivery of
substitute certificate(s) without such reference if such Option Shares have been
registered  pursuant to the Securities Act, such Option Shares have been sold in
reliance  on and in  accordance  with  Rule  144  under  the  Securities  Act or
Shareholder  has  delivered  to Issuer a copy of a letter  from the staff of the
SEC, or an opinion of counsel in form and substance  reasonably  satisfactory to
Issuer and its  counsel,  to the effect  that such  legend is not  required  for
purposes of the Securities Act and (ii) the reference to  restrictions  pursuant
to this  Agreement in the above legend will be removed by delivery of substitute
certificate(s)  without  such  reference  if  the  Option  Shares  evidenced  by

                                       50


certificate(s)  containing  such  reference  have  been sold or  transferred  in
compliance with the provisions of this Agreement under circumstances that do not
require the retention of such reference.

     4.  Representations and Warranties of Issuer.  Issuer hereby represents and
warrants to Shareholder as follows:

     Authorized Stock. Issuer has taken all necessary corporate and other action
to  authorize,  reserve and issue,  and, at all times from the date hereof until
the  obligation  to  deliver  Option  Shares  upon  an  exercise  of the  Option
terminates,  shall have  reserved  for  issuance,  upon  exercise of the Option,
shares of Issuer Common Stock  necessary for Shareholder to exercise the Option.
The shares of Issuer  Common Stock to be issued upon due exercise of the Option,
including all additional shares of Issuer Common Stock or other securities which
may be issuable upon exercise of the Option or any other securities which may be
issuable pursuant to Section 6, upon issuance pursuant hereto,  will be duly and
validly  issued,  fully paid and  nonassessable,  and will be delivered free and
clear of all Liens,  including  without  limitation any preemptive rights of any
shareholder of Issuer.

     5.  Representations  and  Warranties  of  Shareholder.  Shareholder  hereby
represents and warrants to Issuer that:

     Purchase  Not for  Distribution.  Any  Option  Shares  or other  securities
acquired  by  Shareholder  upon  exercise  of the Option  will be  acquired  for
Shareholder's  own account for investment only and not with a view towards their
distribution,  and will not be transferred or otherwise  disposed of except in a
transaction registered, or exempt from registration, under the Securities Act.

     6. Adjustment upon Changes in Capitalization, Etc.

     (a) In the event of any change in Issuer  Common Stock by reason of a stock
dividend, split-up, merger, recapitalization,  combination,  exchange of shares,
or similar  transaction,  the type and number of shares or securities subject to
the Option, and the Exercise Price thereof, will be adjusted appropriately,  and
proper provision will be made in the agreements  governing such transaction,  so
that  Shareholder  will receive upon exercise of the Option the number and class
of shares or other securities or property that  Shareholder  would have received
in respect of Issuer Common Stock if the Option had been  exercised  immediately
before such event or the record date therefor, as applicable. Subject to Section
1, and without limiting the parties'  relative rights and obligations  under the
Merger  Agreement,  if any  additional  shares of Issuer Common Stock are issued
after the date of this  Agreement  (other than pursuant to this  Agreement or an
event  described in the first sentence of this Section 6(a)) or if the number of
outstanding  shares of Issuer  Common Stock is reduced,  the number of shares of
Issuer Common Stock  subject to the Option will be adjusted so that,  after such
issuance or reduction,  it equals the same percentage of the aggregate number of
shares of Issuer Common Stock issued and outstanding after giving effect to such
issuance or reduction as immediately before such issuance or reduction,  in each
case without giving effect to any shares subject to the Option.

                                       51


     (b) Without limiting the parties' relative rights and obligations under the
Merger  Agreement,  in the event that  Issuer  enters into an  agreement  (i) to
consolidate with or merge into any person,  other than Shareholder or one of its
subsidiaries,  and Issuer will not be the continuing or surviving corporation in
such consolidation or merger, (ii) to permit any person,  other than Shareholder
or one of its  subsidiaries,  to  merge  into  Issuer  and  Issuer  will  be the
continuing or surviving  corporation,  but in connection  with such merger,  the
shares of Issuer Common Stock outstanding immediately before the consummation of
such merger will be changed into or exchanged  for stock or other  securities of
Issuer or any  other  person or cash or any  other  property,  or the  shares of
Issuer Common Stock  outstanding  immediately  before the  consummation  of such
merger  will,  after such  merger,  represent  less than 50% of the  outstanding
voting securities of the merged company,  or (iii) to sell or otherwise transfer
all or substantially all of its assets to any person,  other than Shareholder or
one of its  subsidiaries,  then, and in each such case, the agreement  governing
such  transaction  shall make proper provision so that the Option will, upon the
consummation of any such transaction and upon the terms and conditions set forth
herein,  be converted  into, or exchanged  for, an option with  identical  terms
appropriately  adjusted  to  acquire  the  number  and  class of shares or other
securities or property that Shareholder would have received in respect of Issuer
Common Stock if the Option had been exercised in full with respect to all Option
Shares then purchasable immediately before such consolidation,  merger, sale, or
transfer,  or the  record  date  therefor,  as  applicable,  and make any  other
necessary adjustments.

     7.  Listing.  If the  Issuer  Common  Stock or any other  securities  to be
acquired  upon  exercise  of the  Option  are then  listed on AMEX (or any other
national   securities  exchange  or  approved  for  quotation  on  any  national
securities  quotation system),  Issuer,  upon the request of Shareholder,  shall
promptly file an  application to list the shares of Issuer Common Stock or other
securities to be acquired upon exercise of the Option on AMEX (or any such other
national  securities  exchange  or file an  application  to  have  approved  for
quotation on any such  national  securities  quotation  system) and will use its
commercially   reasonable  efforts  to  obtain  approval  of  such  listing  (or
quotation) as promptly as practicable.

     8. Loss or  Mutilation.  Upon  receipt  by Issuer  of  evidence  reasonably
satisfactory  to it of the  loss,  theft,  destruction  or  mutilation  of  this
Agreement,  and (in the  case of  loss,  theft  or  destruction)  of  reasonably
satisfactory  indemnification,  and  upon  surrender  and  cancellation  of this
Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like
tenor and date.

     9. Miscellaneous.

     (a)  Expenses.  Except as  otherwise  provided in this  Agreement or in the
Merger  Agreement,  each of the  parties  hereto will bear and pay all costs and
expenses  incurred by it or on its behalf in  connection  with the  transactions
contemplated  hereunder,  including  fees  and  expenses  of its  own  financial
consultants, investment bankers, accountants, and counsel.

     (b) Amendment.  This Agreement may not be amended,  except by an instrument
in writing signed on behalf of each of the parties.

     (c)  Extension;  Waiver.  Any agreement on the part of a party to waive any
provision  of this  Agreement,  or to extend the time for  performance,  will be
valid only if set forth in an  instrument  in  writing  signed on behalf of such

                                       52


party.  The failure of any party to this  Agreement  to assert any of its rights
under this Agreement or otherwise will not constitute a waiver of such rights.

     (d) Entire Agreement;  No Third-Party  Beneficiaries.  This Agreement,  the
other Transaction  Agreements  (including the documents and instruments attached
thereto as exhibits or schedules or delivered in connection  therewith)  and the
Confidentiality Agreement (i) constitute the entire agreement, and supersede all
prior agreements and understandings,  both written and oral, between the parties
with  respect  to the  subject  matter  of this  Agreement,  and (ii)  except as
provided  in the Merger  Agreement,  are not  intended to confer upon any person
other than the parties any rights or remedies.

     (e)  Governing  Law. This  Agreement  will be governed by, and construed in
accordance with, the laws of the State of Oklahoma,  regardless of the laws that
might otherwise govern under applicable principles of conflict of laws thereof.

     (f)   Notices.   All   notices,   requests,   claims,   demands  and  other
communications  under  this  Agreement  shall be sent in the  manner  and to the
addresses set forth in the Merger Agreement.

     (g) Assignment.  Neither this Agreement,  the Option nor any of the rights,
interests or obligations  under this Agreement may be assigned or delegated,  in
whole or in part,  by operation of law or  otherwise,  by Issuer or  Shareholder
without the prior  written  consent of the other,  except that  Shareholder  may
assign,  in its  sole  discretion,  any  of or all  its  rights,  interests  and
obligations  under  this  Agreement  to any  direct  or  indirect  wholly  owned
subsidiary of Shareholder,  but no such assignment shall relieve  Shareholder of
any of its obligations  hereunder.  Any assignment or delegation in violation of
the preceding  sentence shall be void. Subject to the first and second sentences
of this Section 12(g), this Agreement will be binding upon, inure to the benefit
of, and be  enforceable  by, the parties  and their  respective  successors  and
assigns.

     (h)  Further  Assurances.  In the event of any  exercise  of the  Option by
Shareholder,  Issuer  and  Shareholder  shall  execute  and  deliver  all  other
documents  and  instruments  and take all other  actions that may be  reasonably
necessary in order to consummate the transactions provided for by such exercise.

     (i) Specific Enforcement;  Consent to Jurisdiction.  The parties agree that
irreparable  damage would occur and that the parties would not have any adequate
remedy at law in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached. It
is  accordingly  agreed that the parties  shall be entitled to an  injunction or
injunctions to prevent  breaches of this  Agreement and to enforce  specifically
the terms and  provisions of this  Agreement in any Federal court located in the
State of Oklahoma or in any state court  located in the State of  Oklahoma,  the
foregoing  being in addition to any other  remedy to which they are  entitled at
law or in equity. In addition, each of the parties hereto (i) consents to submit
itself to the personal jurisdiction of any Federal court located in the State of
Oklahoma  or any state  court  located in the State of Oklahoma in the event any
dispute arises out of this Agreement or any of the transactions  contemplated by
this  Agreement,  (ii)  agrees  that it will not  attempt to deny or defeat such
personal  jurisdiction  by motion or other request for leave from any such court
and (iii) agrees that it will not bring any action relating to this Agreement or
any of the transactions contemplated by this Agreement in any court other than a
Federal court sitting in the State of Oklahoma or a state court located in the
State of Oklahoma.

                                       53


     (j)  Severability.  If any term or other  provision  of this  Agreement  is
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.  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  to the  fullest  extent
permitted  by  applicable  law in an  acceptable  manner  to the  end  that  the
transactions contemplated hereby are fulfilled to the extent possible.

     (k) Defined  Terms.  All terms used but not defined  herein  shall have the
meanings ascribed to such terms in the Merger Agreement.

     In Witness Whereof, Issuer and Shareholder have caused this Agreement to be
signed by their respective  officers thereunto duly authorized as of the day and
year first written above.

ANNEX C

                        POST-CLOSING COVENANTS AGREEMENT

     This Post-Closing Covenants Agreement dated as of September 27, 2002, among
Zenex International, Inc., a Colorado corporation ("Parent"), Aduddell Roofing &
Sheet  Metal,  Inc.,  an Oklahoma  corporation  (the  "Company"),  and  Aduddell

and Plan of Split-Off  and Merger  dated as of  September  27, 2002 (the "Merger

the Merger Agreement),  pursuant to which before the Effective Time, among other
things (a) all the assets of the Company primarily related to the Newco Business
(as defined in the Restructuring Agreement) will be transferred to Newco and (b)
Newco will  assume the  Assumed  Liabilities  (as  defined in the  Restructuring
Agreement);

     Whereas, the execution and delivery of this Agreement by the parties hereto
is a condition  to the  obligations  of the parties to the Merger  Agreement  to
consummate the Merger; and

                                       55

Indemnitors.  Subject  to  the  provisions  of  this  Article  II,  Newco  shall
indemnify, defend and hold harmless the Parent Indemnitees from and against, and
pay or reimburse  the Parent  Indemnitees  for,  all  Indemnifiable  Losses,  as

                                       56


     Section  2.02.   Indemnification  by  Aduddell  Roofing.   Subject  to  the

          in accordance  with their terms),  whether such  Indemnifiable  Losses
          relate to or arise from events, occurrences, actions, omissions, facts
          or circumstances  occurring,  existing or asserted before, at or after
          the Effective Time; or

statement or alleged untrue statement of a material fact contained in any of the
Filings,  or any omission or alleged  omission to state  therein a material fact
required to be stated  therein or necessary to make the statements  therein,  in
light of the circumstances under which they were made, not misleading,  but only
with respect to statements  made therein or  incorporated  by reference  therein
based  upon  information  supplied  by  Parent  specifically  for  inclusion  or
incorporation by reference therein.

     Section 2.04. Procedures Relating to Indemnification.

     (a) In  order  for an  Indemnitee  to be  entitled  to any  indemnification
provided for under this  Agreement in respect of,  arising out of or involving a
claim made by any Person who is not an  Indemnitee  against  the  Indemnitee  (a
"Third  Party  Claim"),  such  Indemnitee  must  notify the party who may become
obligated to provide  indemnification  hereunder (the  "Indemnifying  Party") in
writing, and in reasonable detail, of the Third Party Claim reasonably promptly,
and in any event within 20 business  days after  receipt by such  Indemnitee  of
written notice of the Third Party Claim; provided, however, that failure to give
such notification shall not affect the indemnification provided hereunder except
to the extent the  Indemnifying  Party shall have been  actually and  materially
prejudiced as a result of such failure;  provided  further,  however,  that with
respect to any Third Party Claim for which Newco  Indemnitor is the Indemnifying
Party,  such  Indemnifying  Party shall be deemed to have  received  notice with
respect to such Third Party Claim by or against  Aduddell  Roofing for which the
Company   received  notice  before  the  Effective  Time.   After  any  required
notification (if  applicable),  the Indemnitee shall deliver to the Indemnifying
Party,  promptly after the Indemnitee's  receipt thereof,  copies of all notices
and documents  (including court papers)  received by the Indemnitee  relating to
the Third Party Claim.

     (b) If a Third Party Claim is made against an Indemnitee,  the Indemnifying
Party will be  entitled to  participate  in the  defense  thereof  and, if it so
chooses,  to assume the  defense  thereof  (at the  expense of the  Indemnifying
Party)  with  counsel  selected  by  the   Indemnifying   Party  and  reasonably
satisfactory to the Indemnitee. Should the Indemnifying Party so elect to assume

                                       57


the defense of a Third Party Claim, the Indemnifying Party will not be liable to
the Indemnitee for any legal expenses subsequently incurred by the Indemnitee in
connection  with the defense  thereof.  If the  Indemnifying  Party assumes such
defense,  the  Indemnitee  shall have the right to  participate  in the  defense
thereof and to employ  counsel,  at its own expense,  separate  from the counsel
employed by the  Indemnifying  Party, it being  understood that the Indemnifying
Party shall control such defense. The Indemnifying Party shall be liable for the
reasonable  fees and  expenses  of counsel  employed by the  Indemnitee  for any
period during which the  Indemnifying  Party has not assumed the defense thereof
(other than during any period in which the Indemnitee  shall have failed to give
notice  of the  Third  Party  Claim  as  provided  above).  Notwithstanding  the
foregoing, the Indemnifying Party shall not be entitled to assume the defense of
any Third Party Claim (and shall be liable for the reasonable  fees and expenses
of counsel  incurred by the  Indemnitee in defending  such Third Party Claim) if
the Third Party Claim seeks an order,  injunction or other  equitable  relief or
relief for other than money damages against the Indemnitee  which the Indemnitee
reasonably  determines,  after conferring with its counsel,  cannot be separated
from any  related  claim for money  damages.  The  indemnification  required  by
Section  2.01,  2.02 or  2.03,  as the case  may be,  shall be made by  periodic
payments  of the  amount  thereof  during  the  course of the  investigation  or
defense,  as and when bills are received or the Indemnifiable  Loss is incurred.
If the  Indemnifying  Party  chooses to defend or prosecute a Third Party Claim,
all the parties  hereto  reasonably  necessary  for such defense or  prosecution
shall cooperate in the defense or prosecution  thereof,  which cooperation shall
include the retention in accordance with the  Restructuring  Agreement and (upon
the Indemnifying  Party's  request) the provision to the  Indemnifying  Party of
records and information which are reasonably relevant to such Third Party Claim,
and  making  employees  available  on a  mutually  convenient  basis to  provide
additional  information and explanation of any material provided  hereunder.  If
the Indemnifying Party chooses to defend or prosecute any Third Party Claim, the
Indemnitee will agree to any  settlement,  compromise or discharge of such Third
Party Claim which the  Indemnifying  Party may  recommend and which by its terms
obligates  the  Indemnifying  Party  to pay the  full  amount  of  liability  in
connection with such Third Party Claim;  provided,  however,  that,  without the
Indemnitee's  consent,  the Indemnifying Party shall not consent to entry of any
judgment or enter into any  settlement (x) that provides for injunctive or other
non-monetary  relief affecting the Indemnitee or (y) that does not include as an
unconditional  term  thereof the giving by each  claimant or  plaintiff  to such
Indemnitee  of a release from all liability  with respect to such claim.  If the
Indemnifying  Party shall have assumed the defense of a Third Party  Claim,  the
Indemnitee shall not admit any liability with respect to, or settle,  compromise
or  discharge,  such Third Party Claim  without the  Indemnifying  Party's prior
written consent (which consent shall not be unreasonably withheld).

     (c) In  order  for an  Indemnitee  to be  entitled  to any  indemnification
provided for under this  Agreement in respect of a claim that does not involve a
Third  Party  Claim,  the  Indemnitee  shall  deliver  notice of such  claim (in
reasonably  sufficient detail to enable the Indemnifying  Party to evaluate such
claim) with reasonable  promptness to the Indemnifying Party. The failure by any
Indemnitee  so  to  notify  the   Indemnifying   Party  shall  not  relieve  the
Indemnifying Party from any liability which it may have to such Indemnitee under

                                       58


this Agreement, except to the extent that the Indemnifying Party shall have been
actually and materially  prejudiced by such failure.  If the Indemnifying  Party
does not notify the Indemnitee  within 20 business days following its receipt of
such notice that the  Indemnifying  Party disputes its liability with respect to
such claim under Section 2.01, 2.02 or 2.03, as the case may be, the claim shall
be conclusively deemed a liability of the Indemnifying Party under Section 2.01,
2.02 or 2.03,  as the case may be,  and the  Indemnifying  Party  shall  pay the
amount of such  liability  to the  Indemnitee  on demand  or, in the case of any
notice in which the amount of the claim (or any portion  thereof) is  estimated,
on such  later  date when the  amount of such  claim (or such  portion  thereof)
becomes finally  determined.  If the Indemnifying  Party has timely disputed its
liability with respect to such claim, as provided above, the Indemnifying  Party
and the Indemnitee shall proceed in good faith to negotiate a resolution of such
dispute  and,  if not  resolved  through  negotiations,  such  dispute  shall be
resolved by litigation in an appropriate court of competent jurisdiction.

     Section 2.05. Certain Limitations.

     (a) The amount of any  Indemnifiable  Losses or other  liability  for which
indemnification  is provided  under this  Agreement  shall be net of any amounts
actually  recovered by the  Indemnitee  from third parties  (including,  without
limitation, amounts actually recovered under insurance policies) with respect to
such Indemnifiable Losses.

     (b)  All  indemnification  payments  under  this  Agreement  shall  be  (i)
increased to take account of any net tax cost incurred by the Indemnitee arising
from the  receipt of  indemnification  payments  hereunder  (grossed up for such
increase)  and (ii) reduced to take  account of any net tax benefit  realized by
the Indemnitee arising from the incurrence or payment of any Indemnifiable Loss.
In  computing  the amount of any such tax cost or tax  benefit,  the  Indemnitee
shall be deemed to recognize all other items of income,  gain, loss deduction or
credit   before   recognizing   any  item   arising  from  the  receipt  of  any
indemnification   payment   hereunder  or  the  incurrence  or  payment  of  any
Indemnifiable Loss.

     (c) No  indemnification  payments  shall  be  made to an  Indemnitee  whose
Indemnifiable  Losses resulted from his intentional,  malicious or reckless acts
or omissions.

     Section  2.06.  Production of Witnesses;  Records;  Cooperation.  After the
Effective  Time,  except (i) in the case of a dispute between Parent or Aduddell
Roofing, on the one hand, and Newco, on the other hand, and (ii) for Third Party
Claims that the Indemnifying Party participates in the defense or prosecution of
pursuant to Section  2.04(b)  hereof (in which case the relevant  provisions  of
such Section will apply),  each party hereto shall use  commercially  reasonable
efforts to make available to each other party, upon written request, the former,
current and future directors, officers, employees, other personnel and agents of
such party as witnesses  and any books,  records or other  documents  within its
control or which it otherwise has the ability to make  available,  to the extent
that  any  such  person  (giving  consideration  to  business  demands  of  such
directors, officers, employees, other personnel and agents) or books, records or
other  documents  may  reasonably  be  required in  connection  with any demand,
action, suit, countersuit,  arbitration, inquiry, proceeding or investigation by
or before any federal,  state or local governmental authority or any arbitration
or mediation tribunal  ("Action") in which the requesting party may from time to

                                       59


time be involved,  regardless of whether such Action is a matter with respect to
which  indemnification may be sought hereunder.  The requesting party shall bear
all  reasonable  costs and expenses  (including  reasonable  allocated  costs of
in-house  personnel) in connection  therewith unless such costs and expenses are
otherwise  subject to  indemnification  of the requesting party by the producing
party.

                          ARTICLE III OTHER AGREEMENTS

     Section 3.01. Expenses.  Notwithstanding anything to the contrary set forth
in the Merger  Agreement,  the Company (and not Newco) shall be responsible  for
and  agrees to pay all  expenses  (before  giving  effect to the  Restructuring)
related to the Restructuring, the Split-Off and the Merger. Aduddell Roofing and
Newco shall each be  responsible  for and agrees to pay all of their  respective
expenses incurred after the Effective Time.

     Section 3.02.  Characterization of Payments.  The payments made pursuant to
this Agreement  shall be treated as occurring  immediately  before the Effective
Time, and none of Newco,  Aduddell Roofing and Parent and its subsidiaries shall
take any position inconsistent with such treatment before any Taxing Authority.

     Section 3.03.  Agreement  Not to Compete;  Agreement Not to Solicit or Hire
Employees.

     (a) Newco understands that Parent shall be entitled to protect and preserve
the going concern value of the Roofing  Business to the extent  permitted by law
and that Parent  would not have  entered  into the Merger  Agreement  absent the
provisions of this Section 3.03. Newco  acknowledges and agrees that the purpose
of this Section 3.03 is to exclude it, except as expressly  provided below, from
the field of commercial and residential  roofing generally and specifically from
competing  with the  business  of  Aduddell  Roofing  for a period of ten years.
Therefore,  Newco agrees that,  commencing at the Effective  Time and continuing
until the date that is ten years from the  Effective  Time,  it shall  not,  and
shall not permit any of its Affiliates,  in any manner,  directly or indirectly,
alone or in association with any person, to:

     (i)  compete with Parent, the Company or any of their respective Affiliates
          in the field of commercial  and  residential  roofing  generally  (the
          "Roofing Field");

     (ii) engage in any activity in the Roofing Field; or

     (iii)actively participate in, control, manage, own any interest in or share
          in the  earnings  of,  finance or invest in the  capital  stock of any
          person who is engaged in any activity in the Roofing  Field or consult
          with any person on matters in the  Roofing  Field;  except that Newco,
          and each other Affiliate of Newco, may acquire in the aggregate:

          (A)  an entity which  participates in the Roofing Field if and only if
               at the time of the  acquisition  and during  the ten year  period
               referred  to above,  (x) such  entity's  activity  in the Roofing
               Field  is   limited  to  the  sale  of   roofing   products   (as
               distinguished  from the  installation,  maintenance and repair of
               roofs)  and  (y)  the  revenues  derived  from  the  sale of such
               products  constitute  no  more  than 5% of  such  entity's  total
               revenues; and

                                       60


          (B)  up to 5% of the equity or voting  interest  in an entity  that is
               engaged in activities in the Roofing Field so long as none of Tim
               Crawford or Tim Aduddell is actively  involved,  whether directly
               or indirectly, in the management of such entity during the period
               of the  applicable  non-competition  covenants set forth in those
               certain Noncompetition Agreements each dated the same date as the
               Merger Agreement among Parent, the Company and such individual.

     For purposes of this Section 3.03,  "actively involved"  includes,  without
limitation,  acting directly or indirectly as an officer, director,  proprietor,
employee, partner, lender, or, on matters in the Roofing Field, as a consultant,
advisor, agent or representative.

     (b) Newco agrees that for a period of three years from the Effective  Time,
it shall not, and shall cause its Affiliates not to, in any manner,  directly or
indirectly,  (i) induce any person  that has been an employee of any of Aduddell
Roofing at any time between January 1, 2001 and the Effective Time, to leave the
employ of Aduddell Roofing,  (ii) recommend to any other person that they employ
any such employee, or (iii) hire any such employee.

     (c) Newco agrees that for a period of five years from the  Effective  Time,
it shall not, and shall cause its Affiliates not to, in any manner,  directly or
indirectly,  (i) solicit by mail,  by telephone,  by personal  meeting or by any
other means, either directly or indirectly,  any customer or supplier of Parent,
the Company or any of their  respective  Affiliates to transact  business in the
Roofing  Field with a business or  enterprise  that  competes  with Parent,  the
Company or any of their respective  Affiliates in the Roofing Field or reduce or
refrain  from  doing any  business  with  Parent,  the  Company  or any of their
respective  Affiliates in the Roofing  Field,  or (ii)  disparage  (including by
relative  comparison)  Parent  or  the  Company  or  any of  their  products  or
activities in the Roofing Field.

     (d)  Notwithstanding  the termination of this Agreement for any reason, and
irrespective of the time,  manner or cause of termination,  Newco's  obligations
under this  Section  3.03 run with the  business of Newco and shall  survive and
remain in full  force and  effect  for the  periods  therein  provided,  and the
provisions  for equitable  relief against Newco shall continue in full force and
effect.

     Section 3.04. Successors. Newco shall not consolidate with or merge with or
into, or sell,  convey,  transfer or lease,  in one  transaction  or a series of
transactions,  all or substantially all of its assets to, any person, unless the
resulting,  surviving  or  transferee  person (the  "Successor  Company")  shall
expressly assume, by an instrument in form and substance reasonably satisfactory
to Parent,  all the obligations of such Newco  Indemnitor  under this Agreement.
The Successor  Company shall be the successor to Newco or such Newco Indemnitor,
as applicable, and shall succeed to, and be substituted for, such Newco or Newco
Indemnitor,  as applicable,  under this  Agreement,  but, in the case of a sale,
conveyance,  transfer or lease,  Newco or such Newco Indemnitor,  as applicable,
shall not be released from its obligations hereunder.

                                       61


     Section 3.05. Third Party Rights.

     (a) If after the  Effective  Time Newco holds any right to  indemnification
other  than a  right  to  indemnification  under  this  Agreement  or any  other
contractual or other right (collectively, a "Newco Recourse Right") with respect
to any Aduddell Liability or any Assumed Liability for which Aduddell Roofing is
held  responsible,  then (i) to the extent  possible such Newco  Recourse  Right
shall be deemed to be held as a shared  right of Newco and  Aduddell  Roofing to
the extent necessary to protect Aduddell Roofing against such Aduddell Liability
or such Assumed Liability,  and (ii) to the extent not so possible,  Newco shall
assert or otherwise make available to Aduddell  Roofing the full benefit of such
Newco Recourse  Right by making a claim on behalf of Aduddell  Roofing or taking
other steps reasonably requested by Aduddell Roofing.

     (b) In the event that after the Effective  Time Aduddell  Roofing holds any
right to indemnification or any other contractual or other right  (collectively,
a  "Aduddell  Recourse  Right")  with  respect to any Assumed  Liability  or any
Aduddell  Liability for which Newco is held responsible,  then (i) to the extent
possible  such  Aduddell  Recourse  Right shall be deemed to be held as a shared
right of Aduddell  Roofing and Newco to the extent  necessary  to protect  Newco
against  such  Assumed  Liability or such  Aduddell  Liability,  and (ii) to the
extent not so possible,  Aduddell  Roofing assert or otherwise make available to
Newco the full  benefit  of such  Aduddell  Recourse  Right by making a claim on
behalf of Newco or taking other steps reasonably requested by Newco.

     Section 4.06.  Captions.  All the Article,  Section and paragraph  captions
herein are for  convenience of reference  only, do not  constitute  part of this
Agreement  and  shall  not be deemed  to limit or  otherwise  affect  any of the
provisions hereof.

     Section 4.07. Assignment.  Except as provided in Section 3.06, neither this
Agreement nor any of the rights,  interests or obligations  under this Agreement
shall be assigned,  in whole or in part, by operation of law or otherwise by any
of the parties without the prior written  consent of the other parties.  Subject
to the preceding  sentence,  this Agreement  will be binding upon,  inure to the
benefit of, and be enforceable by, the parties and their  respective  successors
and assigns.

     Section 4.08. Entire Agreement.  The Transaction  Agreements (including the
documents and instruments  referred to therein,  the Annexes thereto, the Parent
Disclosure Schedule and the Company Disclosure Schedule) and the Confidentiality
Agreement  constitute the entire  agreement,  and supersede all prior agreements
and understandings, both written and oral, among the parties with respect to the
subject matter hereof and thereof.

     Section 4.09. Certain Obligations.  Whenever this Agreement requires any of
the subsidiaries of any party to take any action,  this Agreement will be deemed

negotiate  in good faith to modify this  Agreement  so as to effect the original
intent of the parties as closely as possible to the fullest extent  permitted by
applicable  law  in an  acceptable  manner  to the  end  that  the  transactions
contemplated hereby are fulfilled to the extent possible.

     Section  4.11.  No Third Party  Beneficiaries.  Nothing  contained  in this

irreparable  damage would occur and that the parties would not have any adequate
remedy either pursuant to the  indemnification  provisions of Section 2.01, 2.02
or 2.03,  as the case may be, or at law in the event that any of the  provisions
of this Agreement were not performed in accordance  with their specific terms or

entitled to an injunction or injunctions  to prevent  breaches of this Agreement
and to enforce  specifically  the terms and  provisions of this Agreement in any
Federal  court  located in the State of Oklahoma in any state court in the State

entitled  at law or in  equity.  In  addition,  each of the  parties  hereto (a)
consents to submit  itself to the  personal  jurisdiction  of any Federal  court
located in the State of Oklahoma  or of any state court  located in the State of

transactions contemplated by this Agreement, (b) agrees that it will not attempt
to deny or defeat  such  personal  jurisdiction  by motion or other  request for
leave  from any such  court and (c)  agrees  that it will not  bring any  action
relating to this Agreement or the transactions contemplated by this Agreement in
any court other than a Federal court located in the State of Oklahoma or a state
