         Shareholder (the "Woodward Shares"),  without any action on the part of
         the Shareholder,  shall automatically  become and be converted into the
         right to receive the following  consideration  from Key  (collectively,
         the "Merger  Consideration"):  (i) 75,000 shares of common  stock,  par
         value $.10 per share,  of Key ("Key Common  Stock") to be issued to the
         Shareholder  in accordance  with Section 4.4 hereof (the "Key Shares"),

         note made  payable by Slawson  Exploration  to Woodward  (the  "Slawson
         Receivable") and (b) pursuant to certain accounts receivable arising in
         connection  with  Woodward's  provision of services  involving  burying
         permanent  anchors  (known as  "deadman  anchors")  to secure rigs (the
         "Anchor  Receivables"),  to be paid to the  Shareholder  within 10 days

         Adjustment Payment (as defined in Section 1.10.3 hereof), if any, to be

         Notwithstanding the foregoing,  the Merger  Consideration to be paid to
         the Shareholder shall be reduced by the sum of $6,852.10 (the "Attorney
         Fee Estimate")  and $6,825.10 as follows:  (1) the number of Key Shares
         to be issued in accordance  with Section 4.4 hereof shall be reduced by
         -0- shares  (based on a price of $7.50 per share) and (2) the amount of
         cash equivalent  payments to be received by the Shareholder on the date
         hereof shall be reduced by $18,825.10.

         surrendered(and  Key acknowledges its receipt of) all the certificates

                                        3





         "Woodward  Certificates")  along with  executed  stock powers in a form
         satisfactory  to Key.  On the  Effective  Date,  Key  will  cancel  the
         Woodward  Certificates,  and the  Shareholder  will become  entitled to
         receive the Merger Consideration.

                  1.10.3.  Adjustment of Merger  Consideration.  The Shareholder
         shall cause to be prepared and delivered to WellTech a balance sheet of
         Woodward  as of the date  hereof (the  "Final  Balance  Sheet")  within
         fifteen (15) days after the date hereof. The parties hereto acknowledge
         and agree that the Final Balance Sheet will reflect (i) as  receivables
         all amounts  due to Woodward  for  services  rendered  through the date
         hereof  and  (ii)  as  payables   all  amounts  owed  by  Woodward  for
         obligations  arising  through the date  hereof.  WellTech  and Woodward
         shall jointly review the Final Balance Sheet, endeavor in good faith to
         resolve all  disagreements  regarding  the entries  thereon and reach a
         final  determination  of the  Final  Balance  Sheet.  Within 10 days of
         reaching  such final  determination  of the Final  Balance  Sheet,  the
         following adjusting payments shall be made:

                  (1)      If  the  Working   Capital  Deficit  (as  defined  in
                           Schedule 1.10.3.1 hereto) is less than $239,083.31 by
                           more than  $5,000,  Key shall pay to the  Shareholder
                           the amount by which such  difference  exceeds  $5,000
                           (the "Cash Adjustment Payment").

                  (2)      If the Working Capital Deficit exceeds $239,083.31 by
                           more than $5,000,  the  Shareholder  shall pay to Key
                           the amount by which such excess exceeds $5,000.

                  (3)      If the  Seller's  attorney's  fees  specified  on the
                           Final Balance Sheet exceed the Attorney Fee Estimate,
                           the  Shareholder  shall pay to Key the amount of such
                           excess. If the Seller's  attorney's fees specified on
                           the Final  Balance  Sheet are less than the  Attorney
                           Fee Estimate,  Key shall pay to the  Shareholder  the
                           amount of such difference.

                  (4)      If the total  amount of the  Excluded  Bank  Accounts
                           (defined below)  specified on the Final Balance Sheet
                           exceeds the  Excluded  Bank  Accounts  Estimate,  Key
                           shall  pay to the  Shareholder  the  amount  of  such
                           excess.  If the  total  amount of the  Excluded  Bank
                           Accounts specified on the Final Balance Sheet is less
                           than  the  Excluded  Bank  Accounts   Estimate,   the
                           Shareholder  shall pay to the Key the  amount of such
                           difference.  The term "Excluded Bank Accounts"  shall
                           mean  those  bank  accounts  identified  on the  8/31
                           Balance  Sheet and the Final  Balance Sheet under the
                           line items  "Cash on Hand",  "Cash in  Bank-Regular",
                           "Cash in Bank-Payroll" and "Cash in Bank-Anchors."

         1.11.  Woodward's Transfer Books Closed. Upon the Effective Date, the 
stock transfer books of Woodward shall be deemed closed, and no transfer of any 
shares of capital stock of Woodward shall thereafter be made or consummated.


                                        4





         1.12.  Assets and Liabilities of Merging  Corporations  Become Those of
Surviving Corporation.  On the Effective Date, all rights,  privileges,  powers,
and  franchises of each of the Merging  Corporations,  and all  property,  real,
personal,  and mixed,  and all debts due on whatever  account,  as well as stock
subscriptions  and all other  things in  action  of or  belonging  to any of the
Merging  Corporations,  shall be taken by and  deemed to be  transferred  to and
shall be vested in the Surviving  Corporation  without  further act or deed, and
all such rights, privileges, powers, and franchises,  property, debts, or things
in action, and all and every other interest of each of the Merging  Corporations
shall be thereafter as effectually the property of the Surviving  Corporation as
they  were of the  respective  Merging  Corporations,  and the title to any real
property,  whether  vested  by deed  or  otherwise,  in  either  of the  Merging
Corporations,  shall  not  revert  or be in any way  impaired  by  reason of the
Merger;  provided  however,  that all rights of creditors and all liens upon any
properties of each of the Merging  Corporations  shall be preserved  unimpaired,
and  all  debts,  liabilities  and  duties  of the  Merging  Corporations  shall
thenceforth attach to the Surviving  Corporation and may be enforced against and
by it to the same  extent as if such  debts,  liabilities  and  duties  had been
incurred or  contracted  by it. Any action or  proceeding  pending by or against
either of the  Merging  Corporations  may be  prosecuted  to  judgment as if the
Merger had not taken place,  or the Surviving  Corporation may be substituted in
place of either of the Merging Corporations.

         1.13.  Conveyances to Surviving  Corporation.  The Merging Corporations
hereby agree, respectively, that from time to time, as and when requested by the
Surviving  Corporation,  or by its successors and assigns, they will execute and
deliver or cause to be executed  and  delivered,  all such  deeds,  conveyances,
assignments,  and other  instruments,  and will  take or cause to be taken  such
further or other action as the Surviving Corporation, its successors or assigns,
may  deem  necessary  or  desirable  to vest or  perfect  in or  confirm  to the
Surviving  Corporation,  its successors and assigns,  title to and possession of
all the  property,  rights,  privileges,  powers,  immunities,  franchises,  and
interests  referred to in this Section 1.13 and  otherwise  carry out the intent
and purposes of this Agreement.

         1.14. Accounting  Treatment.  The assets and liabilities of the Merging
Corporations  shall be taken up on the  books of the  Surviving  Corporation  in
accordance  with  generally  accepted  accounting  principles,  and the  capital
surplus and retained  earnings  accounts of the Surviving  Corporation  shall be
determined,  in accordance with generally accepted accounting principles, by the
board of directors of the Surviving  Corporation.  Nothing  herein shall prevent
the board of  directors  of the  Surviving  Corporation  from  making any future
changes in its accounts in accordance with law.

         1.15.  Federal Income Tax Treatment.  The Merger is intended to qualify
as a forward triangular merger transaction described in ss. 368(a)(2)(D) of the 
Internal Revenue Code of 1986, as amended (the "Code").

                         REPRESENTATIONS AND WARRANTIES
                                 OF SHAREHOLDER

         2.1.     Representations and Warranties of the Shareholder.  The 
Shareholder represents and warrants to Key and WellTech as follows:

                  2.1.1.  Organization  and Standing.  Woodward is a corporation
         duly organized, validly existing and in good standing under the laws of
         the State of Oklahoma, has full requisite corporate power and authority
         to carry on its business as it is currently  conducted,  and to own and
         operate the properties  currently owned and operated by it, and is duly
         qualified  or  licensed  to do  business  and is in good  standing as a
         foreign  corporation  authorized to do business in all jurisdictions in
         which  the  character  of the  properties  owned or the  nature  of the
         business  conducted  by it would make such  qualification  or licensing
         necessary,  except  where the  failure to be so  qualified  or licensed
         would not have a material  adverse  effect on its financial  condition,
         properties or business.

                  2.1.2.   Agreement   Authorized   and  its   Effect  on  Other
         Obligations.  The  execution  and delivery of this  Agreement  has been
         authorized  by the board of directors and all of the holders of capital
         stock of Woodward,  the consummation of the  transactions  contemplated
         hereby have been duly and validly authorized by all necessary corporate
         action  on the part of  Woodward,  and this  Agreement  is a valid  and
         binding obligation of Woodward and the Shareholder  enforceable against
         Woodward and the Shareholder  (subject to normal equitable  principles)
         in accordance with its terms,  except as enforceability  may be limited
         by  bankruptcy,  insolvency,  reorganization,  debtor relief or similar
         laws  affecting  the  rights of  creditors  generally.  The  execution,
         delivery and performance of this Agreement and the  consummation of the
         Merger  contemplated by this Agreement will not conflict with or result
         in a violation or breach of any term or provision of, nor  constitute a
         default  under  (i) the  Certificate  of  Incorporation  or  Bylaws  of
         Woodward or (ii) any obligation,  indenture,  mortgage,  deed of trust,
         lease, contract or other agreement to which Woodward or the Shareholder
         is a party or by which Woodward or the Shareholder or their  respective
         properties are bound.

                  2.1.3.   Capitalization.   The  authorized  capitalization  of
         Woodward  consists of 25,000 shares of Woodward Common Stock, of which,
         as of the date hereof,  25,000 shares were issued and  outstanding  and
         held beneficially and of record by the Shareholder. On the date hereof,
         Woodward  does not have any  outstanding  options,  warrants,  calls or
         commitments  of any  character  relating to any of its  authorized  but
         unissued shares of capital stock. All issued and outstanding  shares of
         Woodward Common Stock are validly issued, fully paid and non-assessable
         and are not  subject  to  preemptive  rights.  None of the  outstanding
         shares of Woodward Common Stock is subject to any voting trusts, voting
         agreement or other


                                        6





         agreement or understanding  with respect to the voting thereof,  nor is
         any proxy in existence with respect thereto.

                  2.1.4.  Ownership of Woodward  Shares.  The Shareholder  holds
         good and valid title to all of the Woodward  Shares,  free and clear of
         all Encumbrances  (as defined in Section 2.1.8.1 hereof).  There are no
         claims pending or, to the Shareholder's knowledge,  threatened, against
         Woodward  or the  Shareholder  that  concern  or  affect  title  to the
         Woodward  Shares,  or that seek to compel the issuance of capital stock
         or other securities of Woodward.

                  2.1.5. No Subsidiaries. There is no corporation,  partnership,
         joint venture,  business trust or other legal entity in which Woodward,
         either directly or indirectly through one or more intermediaries,  owns
         or holds  beneficial or record  ownership of at least a majority of the
         outstanding voting securities.

                  2.1.6. Financial Statements. Woodward has delivered to Key and
         WellTech copies of Woodward's  unaudited  balance sheet attached hereto
         as Schedule 2.1.6 (the "8/31 Balance Sheet") and related  statements of
         income (collectively,  the "8/31 Financial Statements"),  as at and for
         the six months  ended  August 31, 1996 (the  "Balance  Sheet Date") and
         will deliver the Final Balance Sheet in accordance  with Section 1.10.3
         hereof. The 8/31 Financial  Statements are (and the Final Balance Sheet
         will  be)  complete  in  all  material  respects.  The  8/31  Financial
         Statements  present (and the Final Balance  Sheet will present)  fairly
         the financial condition of Woodward as at the dates and for the periods
         indicated.  The 8/31  Financial  Statements  have  been  (and the Final
         Balance Sheet will be) prepared in accordance  with generally  accepted
         accounting  principles  applied on a  consistent  basis.  The  accounts
         receivable  reflected  in the 8/31  Balance  Sheet,  or which have been
         thereafter acquired by Woodward, have been collected or are collectible
         at the aggregate  recorded  amounts thereof less  applicable  reserves,
         which reserves are adequate.  The inventories of Woodward  reflected in
         the 8/31 Balance Sheet,  or which have  thereafter been acquired by it,
         consist of items of a quality  usable and salable in the normal  course
         of Woodward's business, and the values at which inventories are carried
         are at the lower of cost or market.

                  2.1.7.  Liabilities.  Except as  disclosed  on Schedule  2.1.7
         hereto,  Woodward does not have any liabilities or obligations,  either
         accrued,  absolute or  contingent,  nor does the  Shareholder  have any
         knowledge of any  potential  liabilities  or  obligations,  which would
         materially  adversely  affect the value and conduct of the  business of
         Woodward,  other than those (i)  reflected  or reserved  against in the
         8/31 Balance Sheet or (ii) incurred in the ordinary  course of business
         since the Balance Sheet Date.

         executed  by  Woodward  with  respect  to any income or other tax is in
         effect for any period.  The income tax  returns of Woodward  have never
         been examined by the Internal Revenue Service or the taxing authorities
         of any other  jurisdiction.  There  are no tax  liens on any  assets of
         Woodward except for taxes not yet currently due.

                  2.1.12.  Intellectual  Property.  Woodward  owns or  possesses
         licenses  to use  all  patents,  patent  applications,  trademarks  and
         service marks  (including  registrations  and  applications  therefor),
         trade names,  copyrights  and written  know-how,  trade secrets and all
         other similar  proprietary data and the goodwill  associated  therewith
         (collectively, the "Intellectual Property") that are either material to
         the business of Woodward or that are necessary for the rendering of any
         services  rendered by Woodward and the use or sale of any  equipment or
         products  used or sold by  Woodward,  including  all such  Intellectual
         Property listed in Schedule 2.1.8 hereto. The Intellectual  Property is
         owned  or  licensed  by  Woodward  free and  clear of any  Encumbrance.
         Woodward  has not  granted to any other  person any  license to use any
         Intellectual  Property.   Woodward  has  not  received  any  notice  of
         infringement,  misappropriation,  or conflict  with,  the  intellectual
         property rights of others in connection with the use by Woodward of the
         Intellectual  Property  or  otherwise  in  connection  with  Woodward's
         operation of its business.

                  2.1.13.  Title to and Condition of Assets.  Woodward has good,
         indefeasible and marketable  title to all its properties,  interests in
         properties and assets, real and personal, reflected in the 8/31 Balance
         Sheet or in Schedule 2.1.8 hereto, free and clear of any Encumbrance of
         any nature  whatsoever,  except (i) Encumbrances  reflected in the 8/31
         Balance Sheet or in Schedule 2.1.8 hereto, (ii) liens for current taxes
         not yet  due and  payable,  and  (iii)  such  imperfections  of  title,
         easements  and  Encumbrances,   if  any,  as  are  not  substantial  in
         character, amount, or extent and do not and will not materially detract
         from the value,  or  interfere  with the present  use, of the  property
         subject thereto or affected  thereby,  or otherwise  materially  impair
         business  operations.  All leases  pursuant  to which  Woodward  leases
         (whether  as  lessee  or  lessor)  any  substantial  amount  of real or
         personal property are in good standing, valid, and effective; and there
         is not, under any such leases, any existing default or event of default
         or event which with notice or lapse of time, or both,  would constitute
         a default by Woodward  and in respect to which  Woodward  has not taken
         adequate steps to prevent a default from  occurring.  The buildings and
         premises  of  Woodward  that  are  used  in its  business  are in  good
         operating condition and repair, subject only to ordinary wear and tear.
         All rigs, rig equipment, machinery, transportation equipment, tools and
         other  major  items of  equipment  of  Woodward  are in good  operating
         condition and in a state of reasonable maintenance and repair, ordinary
         wear and tear  excepted,  and are free from any known defects except as
         may be repaired by routine maintenance and such minor defects as to not
         substantially  interfere  with the continued use thereof in the conduct
         of normal operations.  To the best of the Shareholder's  knowledge, all
         such assets conform to all applicable laws


                                       11





         governing  their use. No notice of any  violation of any law,  statute,
         ordinance,  or regulation relating to any such assets has been received
         by Woodward or the Shareholder, except such as have been fully complied
         with.

                  2.1.14.  Contracts.  All  contracts,  leases,  plans  or other
         arrangements  to which Woodward is a party,  by which it is bound or to
         which it or its assets are subject  are in full force and  effect,  and
         constitute valid and binding obligations of Woodward.  Woodward is not,
         and to the  knowledge  of the  Shareholder,  no other party to any such
         contract,  lease, plan or other arrangement is, in default  thereunder,
         and no event has occurred which (with or without notice, lapse of time,
         or the  happening  of any  other  event)  would  constitute  a  default
         thereunder.  No  contract  has been  entered  into on terms which could
         reasonably  be  expected  to have an adverse  effect on  Woodward.  The
         Shareholder  has not  received  any  information  which would cause the
         Shareholder  to conclude  that any  customer  of  Woodward  will (or is
         likely  to)  cease  doing  business  with  Woodward  as a result of the
         consummation of the transactions contemplated hereby.

                  2.1.15. Licenses and Permits.  Woodward possesses all permits,
         authorizations,   certificates,  approvals,  registrations,  variances,
         waivers, exemptions,  rights-of-way,  franchises,  ordinances, licenses
         and  other  rights  of every  kind  and  character  (collectively,  the
         "Permits") necessary under law or otherwise for Woodward to conduct its
         business  as now  being  conducted  and  to  construct,  own,  operate,
         maintain  and use its  assets in the manner in which they are now being
         constructed,  operated,  maintained and used.  Each of such Permits and
         Woodward's rights with respect thereto is valid and subsisting, in full
         force and effect, and enforceable by Woodward subject to administrative
         powers of  regulatory  agencies  having  jurisdiction.  Woodward  is in
         compliance  in all material  respects  with the terms of such  Permits.
         None of such Permits have been, or to the knowledge of the Shareholder,
         are threatened to be, revoked, canceled, suspended or modified.

                  2.1.16.  Litigation.  There  is no  suit,  action,  or  legal,
         administrative,   arbitration,  or  other  proceeding  or  governmental
         investigation pending to which Woodward is a party or, to the knowledge
         of the Shareholder,  might become a party or which particularly affects
         Woodward,  nor is any  change  in the  zoning  or  building  ordinances
         directly  affecting  the  real  property  or  leasehold   interests  of
         Woodward, pending or, to the knowledge of the Shareholder, threatened.

                  2.1.17.  Environmental Compliance.

                           2.1.17.1.  Environmental  Conditions.  There  are  no
                  environmental conditions or circumstances,  including, without
                  limitation,   the   presence  or  release  of  any   hazardous
                  substance,  on any property  presently or previously  owned by
                  Woodward,  or on any property to which hazardous substances or
                  waste generated by Woodward's  operations or use of its assets
                  were  disposed of,  which would  result in a material  adverse
                  change in the business or business prospects of Woodward;


                                       12





                           2.1.17.2.  Permits,  etc.  Woodward has in full force
                  and effect all environmental permits, licenses,  approvals and
                  other authorizations required to conduct its operations, other
                  than those that are not material to the business or operations
                  of Woodward, and is operating in compliance thereunder;

                           2.1.17.3.  Compliance.  Woodward's operations and use
                  of its assets do not violate in any material respect any 
                  applicable federal, state or local law, statute, ordinance, 
                  rule, regulation, order or notice requirement pertaining to

                  water, soil, or other environmental media,(b) the environment,
                  including natural resources or any activity which affects the
                  environment, or (c) the regulation of any pollutants, 
                  contaminants, waste, substances (whether or not hazardous or 
                  toxic), including, without limitation, the Comprehensive

                  analogous federal, interstate, state and local requirements, 
                  as any of the foregoing may have been amended or supplemented
                  from time to time (collectively the "Applicable Environmental
                  Laws");

                           2.1.17.4.  Past Compliance.  None of the operations 
                  or assets of Woodward has ever been conducted or used in such
                  a manner as to constitute violation of any of the Applicable 
                  Environmental Laws, other than violations that in the 
                  aggregate are not material to the business or operations of 
                  Woodward;

                           2.1.17.5.  Environmental  Claims.  No notice has been
                  served  on  Woodward  or  the  Shareholder  from  any  entity,
                  governmental  agency or  individual  regarding  any  existing,
                  pending  or  threatened  investigation,  inquiry,  enforcement
                  action or litigation  related to alleged  violations under any
                  Applicable  Environmental  Laws,  or regarding  any claims for
                  remedial obligations, response costs or contribution under any
                  Applicable Environmental Laws;

                           2.1.17.6.  Renewals.  The Shareholder knows of no 
                  reason WellTech would not be able to renew any of the permits,
                  licenses, or other authorizations required pursuant to any of
                  the Applicable Environmental Laws to operate and use any of
                  Woodward's assets for their current purposes and uses; and

                           2.1.17.7.  Asbestos and PCBs.  No material amounts of
                  friable asbestos currently exist on any property owned or 
                  operated by Woodward, nor do


                                       13





                  polychlorinated  biphenyls exist in concentrations of 50 parts
                  per  million or more in  electrical  equipment  owned or being
                  used by Woodward in its operations or on its properties.

                  2.1.18.  Compliance  with  Other  Laws.  Woodward  is  not  in
         violation of or in default with respect to, or in alleged  violation of
         or alleged default with respect to, the Occupational  Safety and Health
         Act (29 U.S.C.  ss.ss.651 et seq.) as amended,  or any other applicable
         law or any applicable  rule,  regulation,  or any writ or decree of any
         court  or  any  governmental  commission,  board,  bureau,  agency,  or
         instrumentality,  or delinquent  with respect to any report required to
         be filed with any governmental  commission,  board,  bureau,  agency or
         instrumentality.

                  2.1.19.  No ERISA  Plans or Labor  Issues.  Woodward  does not
         currently  sponsor,  maintain or  contribute to and has not at any time
         sponsored, maintained or contributed to any employee benefit plan which
         is or was subject to any provisions of the Employee  Retirement  Income
         Security Act of 1974, as amended ("ERISA"). Woodward has not engaged in
         any unfair labor practices which could reasonably be expected to result
         in a material adverse effect on its operations or assets. Woodward does
         not have any  dispute  with any of its  existing  or former  employees.
         There are no labor  disputes or, to the  knowledge of the  Shareholder,
         any disputes threatened by current or former employees of Woodward.

                  2.1.20.  Terminated  Employees.  Woodward has terminated those
         employees  listed on Schedule 2.1.20 hereof effective prior to the date
         hereof  (the  "Terminated  Employees")  and  has  paid  the  Terminated
         Employees all wages and other  compensation  owed them through the date
         of termination.

                  2.1.21. Investigations; Litigation. No investigation or review
         by any  governmental  entity  with  respect to  Woodward  or any of the
         transactions  contemplated by this Agreement is pending or, to the best
         of the Shareholder's  knowledge,  threatened,  nor has any governmental
         entity  indicated  to Woodward an  intention  to conduct the same,  and
         there is no action,  suit or proceeding  pending or, to the best of the
         Shareholder's  knowledge,  threatened  against or affecting Woodward at
         law or in equity,  or before any  federal,  state,  municipal  or other
         governmental   department,   commission,   board,  bureau,   agency  or
         instrumentality,  that either individually or in the aggregate, does or
         is likely to result in any  material  adverse  change in the  financial
         condition, properties or business of Woodward.

                  2.1.22.   Absence  of  Certain  Business  Practices.   Neither
         Woodward nor any officer,  employee or agent of Woodward, nor any other
         person acting on its behalf,  has,  directly or indirectly,  within the
         past five years, given or agreed to give any gift or similar benefit to
         any customer,  supplier,  government employee or other person who is or
         may be in a position to help or hinder the  business of Woodward (or to
         assist Woodward in connection with any actual or proposed  transaction)
         which (i) might subject Woodward to any damage or penalty in any civil,
         criminal or governmental litigation or proceeding, (ii) if not given in
         the past,


                                       14





         might have had a material  adverse  effect on the  assets,  business or
         operations of Woodward as reflected in the 8/31  Financial  Statements,
         or (iii) if not  continued in the future,  might  materially  adversely
         effect the assets,  business  operations  or  prospects  of Woodward or
         which  might  subject  Woodward  to suit or  penalty  in a  private  or
         governmental litigation or proceeding.

                  2.1.23.  Untrue Statements.  Woodward and the Shareholder have
         made available to Key and WellTech true, complete and correct copies of
         all contracts,  documents  concerning all litigation and administrative
         proceedings,  licenses, permits, insurance policies, lists of suppliers
         and customers,  and records relating  principally to Woodward's  assets
         and  business,   and  such  information   covers  all  commitments  and
         liabilities  of Woodward  relating  principally  to its business or the
         assets. This Agreement and the agreements and instruments to be entered
         into in  connection  herewith do not include any untrue  statement of a
         material fact or omit to state any material fact  necessary to make the
         statements  made  herein and  therein not  misleading  in any  material
         respect.

                  2.1.24.  Investment Representations.   The Shareholder 
         acknowledges, represents and agrees that:

                  (a)  the  Key  Shares  have  not  been  registered  under  the
         Securities  Act  of  1933,  as  amended  (the  "Securities   Act"),  or
         registered or qualified under any applicable state securities laws;

                  (b) the Key  Shares  are being  issued to the  Shareholder  in
         reliance  upon  exemptions  from  such  registration  or  qualification
         requirements,  and the availability of such exemptions  depends in part
         upon the Shareholder's  bona fide investment intent with respect to the
         Key Shares;

                  (c) the Shareholder's  acquisition of the Key Shares is solely
         for  his  own  account  for  investment,  and  the  Shareholder  is not
         acquiring  the Key Shares for the account of any other person or with a
         view toward  resale,  assignment,  fractionalization,  or  distribution
         thereof;

                  (d) the Shareholder shall not offer for sale, sell,  transfer,
         pledge,  hypothecate  or  otherwise  dispose  of any of the Key  Shares
         except  in  accordance  with  the  registration   requirements  of  the
         Securities Act and applicable state securities laws or upon delivery to
         Key of an opinion of legal counsel reasonably  satisfactory to Key that
         an exemption from registration is available;

                  (e) the  Shareholder  has such  knowledge  and  experience  in
         financial  and business  matters that he is capable of  evaluating  the
         merits and risks of an  investment  in the Key  Shares,  and to make an
         informed investment decision;



                                       15





                  (f) the  Shareholder  has received a copy of (i) Key's Private
         Offering  Memorandum  dated  June 28,  1996  relating  to Key's  recent
         private  placement  of  convertible  debentures  and (ii) Key's  annual
         report on Form 10-K for the year ended June 30,  1996 as filed with the
         Securities  and  Exchange  Commission.  The  Shareholder  has  had  the
         opportunity  to ask  questions  of,  and  receive  answers  from  Key's
         officers and directors concerning the Shareholder's  acquisition of the
         Key Shares and to obtain such other information  concerning Key and the
         Key Shares,  to the extent Key's  officers and directors  possessed the
         same or could acquire it without unreasonable effort or expense, as the
         Shareholder  deemed  necessary  in  connection  with making an informed
         investment decision;

                  (g) since the Key Shares  have not been  registered  under the
         Securities Act or applicable  state  securities  laws, the  Shareholder
         must bear the economic risk of holding the Key Shares for an indefinite
         period of time, and is capable of bearing such risk; and

                  (h) in  addition to any other  legends  required by law or the
         other agreements entered into in connection herewith,  each certificate
         evidencing  the Key Shares will bear a conspicuous  restrictive  legend
         substantially as follows:

                  THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER
                  THE SECURITIES ACT OF 1933, AS AMENDED  ("ACT"),  OR UNDER ANY
                  APPLICABLE  STATE  SECURITIES LAWS, AND THEY CANNOT BE OFFERED
                  FOR SALE, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE HYPOTHECATED
                  EXCEPT IN ACCORDANCE WITH THE REGISTRATION REQUIREMENTS OF THE
                  ACT  AND  SUCH  OTHER  STATE  LAWS OR  UPON  DELIVERY  TO THIS
                  CORPORATION OF AN OPINION OF LEGAL COUNSEL SATISFACTORY TO THE
                  CORPORATION THAT AN EXEMPTION FROM REGISTRATION IS AVAILABLE.

                  2.1.25.  Consents  and  Approvals.  No  consent,  approval  or
         authorization  of, or filing or registration  with, any governmental or
         regulatory authority, or any other person or entity other than Woodward
         and the Shareholder,  is required to be made or obtained by Woodward or
         the  Shareholder  in  connection   with  the  execution,   delivery  or
         performance of this Agreement or the  consummation of the  transactions
         contemplated hereby.

                  2.1.26.  Finder's  Fee.  All  negotiations  relative  to  this
         Agreement and the transactions contemplated hereby have been carried on
         by Woodward and the Shareholder and their counsel directly with Key and
         WellTech  and their  counsel,  without  the  intervention  of any other
         person in such manner as to give rise to any valid claim against any of
         the parties  hereto for a  brokerage  commission,  finder's  fee or any
         similar payments.

or actively  attempt to  influence  any employee of WellTech or Key to terminate
his  employment.  The  Shareholder  agrees  that if either the length of time or
geographical  area set forth in this  Section is deemed too  restrictive  in any
court proceeding, the court may reduce such restrictions to those which it deems
reasonable under the  circumstances.  The obligations  expressed in this Section
4.1 are in addition to any other obligations that the Shareholder may have under
the laws of the State of  Oklahoma  requiring  an  employee  of a business  or a
shareholder  who sells his stock in a corporation  (including a disposition in a
merger) to limit his  activities so that the goodwill and business  relations of
his employer and of the  corporation  whose stock he has sold (and any successor
corporation) will not be materially impaired. The Shareholder further agrees and
acknowledges  that  WellTech and Key do not have any adequate  remedy at law for
the breach or threatened  breach by the Shareholder of this covenant,  and agree
that  WellTech  or Key may,  in  addition  to the  other  remedies  which may be
available to it hereunder,  file a suit in equity to enjoin the Shareholder from
such breach or threatened breach. If any provisions of this Section 4.1 are held
to be invalid or against public policy,  the remaining  provisions  shall not be
affected thereby.  The Shareholder  acknowledges that the covenants set forth in
this  Section  4.1 are  being  executed  and  delivered  by the  Shareholder  in
consideration  of the covenants of WellTech and Key contained in this Agreement,
and for  other  good and  valuable  consideration,  receipt  of which is  hereby
acknowledged.

         4.2.  Registration  Rights. Key has delivered to the Shareholder a copy
of the Registration  Right Agreement among Key, McMahan  Securities Co. L.P. and
Rauscher  Pierce  Refsnes,  Inc.  dated July 3, 1996 (the  "Registration  Rights
Agreement")  pursuant to which Key has agreed to register  the resale of certain
shares of Key Common  Stock  issuable  upon  conversion  of certain  outstanding
convertible  debentures of Key pursuant to the terms of the Registration  Rights
Agreement.  Key hereby  agrees to include in the  registration  statement  filed
pursuant  to  the  Registration   Rights  Agreement  (the  "Shelf   Registration
Statement")  the resale of the Key Shares;  provided,  that (i) the  Shareholder
shall have all  duties and  obligations  of a  "Holder"  under the  Registration
Rights  Agreement and (ii),  notwithstanding  the inclusion of the resale of the
Key Shares in the Registration Statement, the Shareholder shall have no right to
participate  in an  underwritten  offering of Key Common Stock by those  persons
holding rights under the Registration  Rights  Agreement,  if any, except to the
extent  that the  underwriters  of such an  offering  agree and  pursuant to any
underwriting arrangements in connection therewith.

         4.3. Short Period Tax  Reporting.  WellTech shall cause to be filed for
Woodward federal and state income tax returns the periods  beginning on March 1,
1996 and ending on the date  hereof.  Such  returns  shall be  prepared by Jerry
Freck,  certified public accountant,  and reviewed and filed by WellTech or Key.
The expenses  incurred in connection  with the  preparation  and filing of these
returns shall be borne by WellTech. The Shareholder shall assist WellTech in the
preparation and filing of such returns as reasonably requested.



                                       19





         4.4. Stock Certificate  Issuance.  On the Effective Date Key shall file
an additional  listing  application with the American Stock Exchange  requesting
the listing of the Key Shares.  On the date Key  receives  notice of approval of
such  request,  Key shall send written  instructions  to its transfer  agent and
registrar to issue,  countersign and register a certificate representing the Key
Shares  in the name of the  Shareholder  and  deliver  such  certificate  to the
Shareholder at the address specified in Section 6.4 hereof.

         4.5.  Further  Assurances.  From time to time, as and when requested by
any party hereto, any other party hereto shall execute and deliver,  or cause to
be executed and  delivered,  such documents and  instruments  and shall take, or
cause to be taken, such further or other actions as may be reasonably  necessary
to effectuate the transactions contemplated hereby.


                                    ARTICLE 5

                                 INDEMNIFICATION

         5.1.  Indemnification  by the  Shareholder.  In  addition  to any other
remedies available to Key and WellTech under this Agreement (including,  without
limitation,  those  remedies  specified in Section 5.5 hereof),  or at law or in
equity,  the Shareholder  shall indemnify,  defend and hold harmless each of Key
and WellTech, and their respective officers,  directors,  employees,  agents and
stockholders,  against and with respect to any and all claims,  costs,  damages,
losses, expenses, obliga tions, liabilities, recoveries, suits, causes of action
and deficiencies,  including interest,  penalties and reasonable attorneys' fees
and expenses (collectively,  the "Damages") that such indemnitees shall incur or
suffer,  which arise,  result from or relate to (i) any breach of, or failure by
the  Shareholder  to  perform,  his  respective   representations,   warranties,
covenants  or  agreements  in this  Agreement or in any  schedule,  certificate,
exhibit or other  instrument  furnished  or  delivered to WellTech or Key by the
Shareholder  under  this  Agreement  or (ii)  Woodward's  relationship  with any
Terminated Employee.

         5.2.  Indemnification  by Key and  WellTech.  In  addition to any other
remedies  available to the  Shareholder  under this  Agreement,  or at law or in
equity, WellTech and Key shall jointly and severally indemnify,  defend and hold
harmless the  Shareholder  and his employees and agents against and with respect
to any and all Damages that such indemnitees shall incur or suffer, which arise,
result  from or relate  to any  breach  of, or  failure  by  WellTech  or Key to
perform, any of its representations, warranties, covenants or agreements in this
Agreement or in any schedule, certificate, exhibit or other instrument furnished
or delivered to Woodward or the  Shareholder  by or on behalf of Key or WellTech
under this Agreement.

         5.3.  Indemnification  Procedure.  In the event  that any party  hereto
discovers or otherwise becomes aware of an  indemnification  claim arising under
Section 5.1 or Section 5.2 of this Agreement,  such indemnified party shall give
written  notice  to the  indemnifying  party,  specifying  such  claim,  and may
thereafter exercise any remedies available to such party under this Agreement;


                                       20





provided,  however,  that the failure of any indemnified party to give notice as
provided  herein  shall not relieve the  indemnifying  party of any  obligations
hereunder,  to the extent the  indemnifying  party is not materially  prejudiced
thereby.  Further,  promptly after receipt by an indemnified  party hereunder of
written notice of the  commencement  of any action or proceeding with respect to
which a claim for  indemnification  may be made pursuant to this Article 5, such
indemnified party shall, if a claim in respect thereof is to be made against any
indemnifying  party,  give written notice to the latter of the  commencement  of
such action;  provided,  however,  that the failure of any indemnified  party to
give notice as provided herein shall not relieve the  indemnifying  party of any
obligations  hereunder,  to the extent the indemnifying  party is not materially
prejudiced  thereby.  In case any such action is brought  against an indemnified
party, the indemnifying  party shall be entitled to participate in and to assume
the  defense  thereof,  jointly  with any  other  indemnifying  party  similarly
notified,  to the extent that it may wish, with counsel reasonably  satisfactory
to such indemnified  party, and after such notice from the indemnifying party to
such  indemnified  party of its election so to assume the defense  thereof,  the
indemnifying  party shall not be liable to such indemnified  party for any legal
or other  expenses  subsequently  incurred by the latter in connection  with the
defense thereof unless the  indemnifying  party has failed to assume the defense
of such claim and to employ counsel reasonably  satisfactory to such indemnified
person.  An  indemnifying  party who elects not to assume the defense of a claim
shall not be liable for the fees and  expenses  of more than one  counsel in any
single  jurisdiction for all parties indemnified by such indemnifying party with
respect to such claim or with respect to claims  separate but similar or related
in  the  same  jurisdiction   arising  out  of  the  same  general  allegations.
Notwithstanding any of the foregoing to the contrary, the indemnified party will
be  entitled  to select its own  counsel  and  assume the  defense of any action
brought against it if the indemnifying  party fails to select counsel reasonably
satisfactory to the indemnified  party,  the expenses of such defense to be paid
by the indemnifying  party. No indemnifying  party shall consent to entry of any
judgment  or enter  into any  settlement  with  respect to a claim  without  the
consent  of the  indemnified  party,  which  consent  shall not be  unreasonably
withheld,  or unless such  judgment or settlement  includes as an  unconditional
term thereof the giving by the claimant or plaintiff to such  indemnified  party
of a release from all liability with respect to such claim. No indemnified party
shall consent to entry of any judgment or enter into any  settlement of any such
action, the defense of which has been assumed by an indemnifying party,  without
the consent of such indemnifying  party, which consent shall not be unreasonably
withheld.

         5.4.  Offset.  The parties  hereto  agree that if WellTech or Key shall
incur any Damages for which it is entitled to indemnification by the Shareholder
pursuant to the terms of this Agreement,  Key shall have the right to offset any
payments  due or to be due  under  the  terms  of this  Agreement  or any  other
agreement executed in connection  herewith,  by the amount of the Damages.  Such
right of offset shall not be  considered  an exclusive  remedy,  it being agreed
that Key shall also be entitled to exercise any other  remedies  available to it
at law or in equity, including,  without limitation,  the indemnification rights
set forth in this Article 5. In the event of an offset by Key as a result of any
account   receivable   of  Woodward  not  being   collected  in  breach  of  the
representation of the Shareholder in Section 2.1.6 hereof, upon any such offset,
Key shall assign to the  Shareholder the account  receivable  subject to offset,
and the  Shareholder  shall  thereafter  have the  right to take any  reasonable
action to collect such account receivable. In the event of an offset by Key as a
result of


                                       21





any  inventory of Woodward  being  unsalable in the normal course of business in
breach of the  representations  of Woodward and the Shareholder in Section 2.1.6
hereof,  upon any such offset,  Key shall convey and transfer to the Shareholder
title to such inventory subject to offset.

         5.5. Self Insurance  Agreement.  Notwithstanding  any provision of this
Article 5 or elsewhere herein to the contrary,  and notwithstanding the accuracy
of the Shareholder's  representation contained in Section 2.1.7, the Shareholder
shall  indemnify,  defend and hold harmless each of Key and WellTech,  and their
respective officers,  directors,  employees, agents and stockholders against and
with respect to any and all Damages arising during the one-year period beginning
on the date hereof that such indemnitees  shall incur or suffer,  which arise or
result from or relate to WellTech's  assumption of Woodward's  obligations under
the  self-insurance  pooling agreement referred to in Schedule 2.1.7 hereto, but
only to the extent  that such  Damages  (the "Self  Insurance  Damages")  exceed
$25,000 in the aggregate during such one-year period.  The Shareholder shall not
be liable for any Self Insurance Damages arising on or after September 30, 1997.


                                    ARTICLE 6

                                  MISCELLANEOUS

         6.1.  Survival  of  Representations,   Warranties  and  Covenants.  All
representations  and  warranties  made by the parties hereto shall survive for a
period of 14 months from the date hereof, notwithstanding any investigation made
by or on  behalf  of any of the  parties  hereto;  provided,  however,  that the
representations and warranties  contained in Section 2.1.11 hereof shall survive
until the expiration of the applicable  statute of limitations  associated  with
the taxes at issue.  All  statements  contained  in any  certificate,  schedule,
exhibit or other instrument delivered pursuant to this Agreement shall be deemed
to have been  representations and warranties by the respective party or parties,
as the case may be, and shall also  survive  for a period of 14 months  from the
date hereof despite any investigation made by any party hereto or on its behalf.
All covenants and agreements contained herein shall survive indefinitely without
limitation, except as otherwise provided herein.

         6.2.     Entirety.  This Agreement embodies the entire agreement among 
the parties with respect to the subject matter hereof, and all prior agreements
between the parties with respect thereto are hereby superseded in their 
entirety.

         6.3.     Counterparts.  Any number of counterparts of this Agreement 
may be executed and each such counterpart shall be deemed to be an original 
instrument, but all such counterparts together shall constitute but one 
instrument.

         6.4.     Notices and Waivers.  Any notice or waiver to be given to any
party hereto shall be in writing and shall be delivered by courier, sent by  
facsimile transmission or first class registered or certified mail, postage 
prepaid, return receipt requested.
