infringe,  misappropriate  or conflict with the intellectual  property rights of
others.   Neither  Seller  nor  the  Shareholder  has  received  any  notice  of
infringement,  misappropriation,  or  conflict  with the  intellectual  property
rights of others in connection with the use by Seller of the Seller Intellectual
Property.

materially  adversely  effect the profitable use of the Assets or conduct of the

the Assets and the business,  and such  information  covers all  commitments and
liabilities of Seller relating  principally to the Assets.  This Agreement,  the
Seller  Agreements  and  the  other  instruments  executed  by  Seller,  or  the
Shareholder and delivered to Buyer or Key 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.

transactions contemplated hereby have been carried on by Seller, the Shareholder
and their  counsel  directly  with  Buyer,  Key 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 payment.

2.1.16.  Investment  Representations of Seller. Pursuant to Sections 1.2 and 4.2
hereof,  Key will issue the Key shares to the  Shareholder.  In connection  with
this issuance, each of Seller and the Shareholder  acknowledges,  represents and
agrees that :

(a) The  Shareholder  is an  "accredited  investor"  as such term is  defined in
Regulation  D under the  Securities  Act of 1933,  as amended  (the  "Securities
Act").

(b)(i)  The  Shareholder,  through  his  own  operations,  is  knowledgeable  in
operations of the type  conducted by Key, (ii) Key has made  available to Seller
and the Shareholder  extensive legal,  financial,  accounting and other business
records for  examination by Seller and the  Shareholder,  (iii) Key has made its
principal  executive and operating personnel available for consultation with the
designated  representatives  of Seller and the Shareholder,  (iv) Seller and the
Shareholder   have  made  an  extensive   investigation   of  Key's  assets  and
liabilities, business and financial affairs, and operations, (v) the Shareholder
is aware of the risks  associated  with  ownership  of the Key Shares,  (vi) the
Shareholder  is capable of bearing  the  financial  risks  associated  with such
ownership,  and (vii) while  recognizing  that he cannot  effectively  waive the
protections  afforded to it under the Securities  Act, he regards  himself as an
entity of such financial capacity, sophistication, and prudence that he does not
require the  protections  afforded to him by the Securities  Act, and is relying
upon his own  investigation  of Key in making  his  decision  to enter into this
Agreement.

(c) The Key  Shares  have not been  registered  under  the  Securities  Act,  or
registered or qualified under any applicable state securities laws;

(d) 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;

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

(f) Seller 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;

(g) Since the Key Shares have not been  registered  under the  Securities Act or
applicable state securities laws,  Seller must bear the economic risk of holding
the Key  Shares  for an  indefinite  period of time,  and  Seller 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,  the 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.

2.2.  Limitation  on   Representations.   The  existence  of  an  inaccuracy  or
incorrectness  with  respect to a  representation  contained  in this Article II
shall not constitute a misrepresentation  or a breach of any such representation
unless such  inaccuracy  or  incorrectness  shall be material.  An inaccuracy or
incorrectness shall be considered material if:

(a) it is contained in a financial  statement delivered by Seller to Buyer prior
to Closing and relates to a financial  matter which could reasonably be expected
to be  relied  on by Buyer  in  determining  the  advisability  of the  purchase
described herein or the amount of consideration to be paid; or,

(b) it results in an actual financial loss to Buyer.

2.3 To the  Knowledge  of Seller.  The term "to  Seller's  or the  Shareholder's
knowledge" or any similar term, where any  representation or warranty  contained
in Article II is expressly  qualified  by  reference to such phrase,  shall mean
that Seller acting by and through its duly  appointed and  authorized  officers,
confirms that as to the matters that are the subject of such representations and
warranties,  such officers either have actual  knowledge of such matters or have
made inquiries with respect to such matters,  sufficient to allow Seller to make
such representation or warranty in good faith without actual knowledge that such
representation is untrue.

performance of this Agreement and the Buyer  Agreements and the  consummation of
the  transactions  contemplated  hereby and thereby  will not  conflict  with or

of Key,  and  this  Agreement  and the Key  Agreements  are  valid  and  binding
obligations of Key, enforceable (subject to normal equitable principals) against
Key in accordance with their terms,  except as enforceability  may be limited by
bankruptcy, insolvency,  reorganization, debtor relief or similar laws affecting

trust,  lease,  contract or other  agreement to which Key is a party or by which

                                   Article IV

                              Additional Agreements

4.1  Noncompetition.  Except as otherwise consented to or approved in writing by
Buyer and Key, each of Seller and the Shareholder agrees that for a period of 60
months following the Effective Date, directly or indirectly,  acting alone or as
a member of a  partnership  or a holder of, or  investor in as much as 5% of any
security of any class of any  corporation or other business entity (i) engage in
any business selling and installing wellhead and down hole equipment,  providing
drilling,  workover  or well  services,  engaging in oil field tool  rental,  or
providing any other oil field services  previously provided by Seller during the
twenty-four  (24) month period in Texas,  Oklahoma or Kansas (the  "Territory");
(ii)  request any present  customers or suppliers of Seller to curtail or cancel
their  business  with  Buyer  or Key;  (iii)  disclose  to any  person,  firm or
corporation any trade,  technical or technological  secrets of Seller,  Buyer or
Key or any details of their  organization or business  affairs or (iv) induce or
actively  attempt to influence  any  employee of Buyer or Key to  terminate  his
employment. Seller agrees that if either the length of time or geographical area
of the Territory 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 Seller or the Shareholder may have under the laws of
any state requiring a corporation who sells its assets (and the  shareholders of
such  corporation)  to limit its  activities  so that the  goodwill and business
relations being  transferred  with such assets will not be materially  impaired.
Seller  further  agrees  and  acknowledge  that  Buyer  and Key do not  have any
adequate  remedy at law for the  breach or  threatened  breach by Seller of this
covenant,  and agree that Buyer or Key may, in  addition  to the other  remedies
which may be available to them hereunder, file a suit in equity to enjoin Seller
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.  Seller  acknowledges that the covenants set forth in this
Section 4.1 are being executed and delivered by Seller in  consideration  of the
covenants of Buyer and Key contained in this  Agreement,  and for other good and
valuable consideration, receipt of which is hereby acknowledged.

4.2  Issuance of Key Shares.  On the date hereof,  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 one or more certificates representing the Key Shares in
the name of the Shareholder and deliver such  certificate(s)  to the Shareholder
at the address  specified in Section 6.4 hereof.  In the event that the American
Stock  Exchange  does not approve the listing  application,  the parties  hereto
shall  negotiate  in good faith the  appropriate  consideration  to replace such
shares.

4.3 Employment of the Shareholder. Buyer hereby agrees to employ the Shareholder
as Buyer's  area  manager at a salary of $5,000  per  month,  a monthly  vehicle
allowance  and  those  additional   benefits  now  afforded  buyer's   employees
commensurate  with  shareholder's  area manager  position with Buyer. 4.4 Hiring
Employees.  Effective  as of the  date  hereof,  all of the  Employees  shall be
terminated by Seller.  Buyer may, but shall be under no obligation  to, hire any
of the Employees effective as of the date hereof.  Except as provided in Section
1.4 hereof,  Buyer shall have no  liability  or  obligation  with respect to any
employee  benefits of any Employee except those benefits that accrue pursuant to
such Employees'  employment  with Buyer on or after the date hereof.  Seller and
the  Shareholder  shall  cooperate  with Buyer in  connection  with any offer of
employment  from Buyer to the  Employees  and use its best  efforts to cause the
acceptance  of any and all such offers.  All  Employees  hired by Buyer shall be
at-will employees of Buyer.

4.5  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 (i) file a  registration  statement  (the
"Shelf  Registration  Statement")  with  the  SEC on or  before  April  3,  1997
registering  the resale of  certain  shares of Key Common  Stock  issuable  upon
conversion of certain outstanding convertible debentures of Key and (ii) use its
best efforts to cause the Shelf Registration  Statement to be declared effective
by the SEC on or before July 3, 1997. Key hereby agrees to include the resale of
the Key Shares in the Shelf Registration  Statement;  provided, that (i) each of
the  Shareholders  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 Shelf Registration  Statement,  the Shareholders
shall have no right to participate in an underwritten  offering,  if any, of Key
Common  Stock by those  debenture  holders  exercising  their  rights  under the
Registration  Rights  Agreement.  In  the  event  that  the  Shelf  Registration
Statement  is  declared  effective  by July 3, 1997,  Key shall,  subject to the
"Black-out"  provision in Section 4(b)(i) of the Registration  Rights Agreement,
use its best  efforts to keep such  Shelf  Registration  Statement  continuously
effective,  supplemented  and  amended as required  to the extent  necessary  to
ensure that it is  available  for resale of the Key Shares and to insure that it
conforms with the Securities Act and the policies,  rules and regulations of the
commission  as announced  from time to time,  for a period of at least three (3)
years  following  the date of issuance of the Key Shares or such shorter  period
that will  terminate  when all of the Key Shares have been sold  pursuant to the
Shelf Registration  Statement or pursuant rule 144 of the Securities Act. If Key
shall fail to keep such  registration  statement so  effective,  then during any
period  prior  to the  date  termination  is  allowed  during  which  the  Shelf
Registration  Statement  is not  effective  in  accordance  with  the  foregoing
provision,  Seller or Shareholder  shall have a Put Right to the same extent and
exercisable in the same manner as provided in the following sentence relating to
the Put Right  available  during the period July 3, 1997 through August 3, 1997,
in the event the Shelf Registration Statement does not become effective.  In the
event that the Shelf Registration Statement is not declared effective by the SEC
by July 3, 1997, Seller shall have the right (the "Put Right") to require Key to
purchase  the Key Shares from Seller for an  aggregate  purchase  price equal to
ninety- percent (90%) of the aggregate market value of the Key Shares calculated
using the per share  closing  price on July 3, 1997 as reported by the  American
Stock  Exchange.  The Put Right shall be exercised by delivery of written notice
to Key on or before August 3, 1997, after which date the Put Right shall expire.
During any period in which Seller or Shareholders  holds a Put Right pursuant to
this  Section  4.5,  such Put  Right  may be  exercised  as often as  Seller  or
Shareholder  desires and such Put Right may be exercised  with respect to all or
such portion of the Key Shares as Seller or Shareholder  may desire.  The rights
of Seller set forth in this paragraph  shall be  transferable to Shareholder but
not otherwise.  To the extent shares have been  transferred to Shareholder,  the
term Seller shall include shareholder.

4.6  Allocation  of Purchase  Price.  The parties  hereto  agree to allocate the
purchase  price paid by Buyer for the Assets  hereunder as set forth on Schedule
4.6 hereto, and shall report this transaction for federal income tax purposes in
accordance with the allocation so agreed upon. The parties hereto for themselves
and for their  respective  successors  and assigns  covenant and agree that they
will file  coordinating  Form  8594's in  accordance  with  Section  1060 of the
Internal  Revenue Code of 1986,  as amended,  with their  respective  income tax
returns for the taxable year that includes the date hereof.

4.7 Name Change.  Seller and the Shareholder shall, within thirty (30) days from
the date hereof,  caused to be filed (i) with the secretary of state of Seller's
state  of  organization  an  amendment  to  the  charter  (or  other  applicable
organization  document)  of Seller  changing the name of Seller from its current
name to a name that is not  similar to such name or such  documents  required to
effect the  dissolution  of Seller so that the separate  corporate  existence of
Seller is  terminated,  and (ii) with the  appropriate  authorities  of Seller's
state of  organization  and any other  states such  documents as are required to
effect such name change or dissolution, including without limitation, amendments
or  withdrawals  of  certificates  of  authority to do business and assumed name
filing. Seller and the Shareholder shall, within five (5) business days from the
date of its receipt of  confirmation  of such filings from the applicable  state
authorities, cause to be delivered to Buyer copies of all such confirmations.

4.8 Collection of  Receivables.  Buyer shall cooperate with and assist Seller in
collecting  the Seller  Receivables,  which  cooperation  and  assistance  shall
include  promptly  forwarding to Seller all payments  received by Buyer that are
made in respect of the  Seller  Receivables.  Seller  shall  cooperate  with and
assist  Buyer  in  collecting   receivables  of  Buyer,  which  cooperation  and
assistance shall include promptly  forwarding to Buyer all payments  received by
the Seller that are made in respect of Buyer's receivables.

4.9 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
effect the transactions contemplated hereby. 4.10 Access to Records. Buyer shall
preserve all account ledgers,  computer software and data, books, records, files
and data  transferred  to Buyer  pursuant to this  Agreement  for a period of at
least six (6) years and shall at any reasonable time allow Seller or Shareholder
full access to such  records and shall,  at Seller's or  Shareholder's  expense,
furnish copies of any such material as may be requested.

                                    Article V
                                 Indemnification

5.1  Indemnification  by Seller and the  Shareholder.  In  addition to any other
remedies  available  to Buyer  and Key  under  this  Agreement,  or at law or in
equity,  each of  Seller  and the  Shareholder  shall,  jointly  and  severally,
indemnify,  defend and hold harmless each of Buyer and Key, and their respective
officers,  directors,  employees,  agents  and  stockholders,  against  and with
respect to any and all claims, costs, damages,  losses,  expenses,  obligations,
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 Seller or the  Shareholder to
perform, their respective re presentations,  warranties, covenants or agreements
in this Agreement or in any schedule,  certificate,  exhibit or other instrument
furnished or delivered to Buyer and Key by Seller or the Shareholder  under this
Agreement and (ii) the Retained Liabilities.

5.2  Indemnification  by Buyer  and  Key.  In  addition  to any  other  remedies
available to Seller or the  Shareholder  under this  Agreement,  or at law or in
equity, Buyer and Key shall, jointly and severally,  indemnify,  defend and hold
harmless the  Shareholder,  Seller and its  officers,  directors,  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  Buyer 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 Seller or the Shareholder
by or on behalf of Buyer or Key under this Agreement.

5.3  Indemnification  Procedure.  If 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  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.

                                   Article VI

                                  Miscellaneous

6.1 Survival of Representations,  Warranties and Covenants. All representations,
warranties,  covenants and  agreements  made by the parties hereto shall survive

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 without
limitation despite any investigation made by any party hereto or on its behalf.

parties with respect thereto are hereby superseded in their entirety.

instrument,  but all of  which  together  shall  constitute  one  and  the  same
instrument.
