                                   ARTICLE II

                         Representations and Warranties

2.1 Representations and Warranties of the Seller and the Shareholder.  As of the
Closing  and the  Effective  Time,  the Seller and the  Shareholder  jointly and
severally represent and warrant to Buyer as follows:

2.1.1  Organization  and Good Standing.  Seller is a corporation duly organized,
validly  existing and in good standing  under the laws of the State of Colorado,
is qualified to do business in Wyoming,  Utah and Nevada and in each other state
in which the nature and conduct of its  business  requires it to be qualified to
do business and has full requisite corporate power and authority to carry on its
businesses as it is currently  conducted  and to own and operate the  properties
currently owned and operated by it. The  Shareholder  owns all of the issued and
outstanding  shares of the Seller's capital stock and has the sole right to vote
the same.

2.1.2 Agreement  Authorized and Effect on Other  Obligations.  The execution and
delivery of this Agreement and all  instruments to be executed by Seller and the
Shareholder   hereunder  have  been  authorized  by  all  necessary   corporate,
shareholder  and other action on the part of the Seller and the  Shareholder and
this  Agreement  and  all  instruments  to be  executed  by the  Seller  and the
Shareholder  hereunder are the valid and binding  obligations  of the Seller and
the Shareholder  enforceable  (subject to normal equitable  principals)  against
each of such parties in accordance  with their 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 all instruments to be executed by
the  Seller  and  the  Shareholder   hereunder  and  the   consummation  of  the
transactions  contemplated hereby and thereby,  will not conflict with or result
in a violation or breach of any term or provision  of, nor  constitute a default
under (i) the  Articles  of  Incorporation  or Bylaws  (or other  organizational
documents) of the Seller, (ii) except as set forth on Schedule 2.1.9 hereto, any
obligation,  indenture,  mortgage,  deed of  trust,  lease,  contract  or  other
agreement  to which  the  Seller or the  Shareholder  is a party or by which the
Seller or the Shareholder or their respective  properties are bound; or (iii) to
the their knowledge, any provision of any law, rule, regulation, order, permits,
certificate, writ, judgment,  injunction, decree, determination,  award or other
decision of any court,  arbitrator or other governmental  authority to which the
Seller or the Shareholder, or any of their respective properties are subject.

2.1.3  Contracts.  Schedule  1.1(d)  hereto  sets forth a  complete  list of all
contracts,  including  leases under which the Seller is lessor or lessee,  which
relate to the Assets. In addition, except as set forth on Schedule 1.1(d) hereto
(a) all of the Contracts are in full force and effect,  and constitute valid and
binding  obligations  of the Seller,  (b) except as set forth on Schedule  2.1.9
hereto,  the  Seller  is  not,  and  to the  knowledge  of the  Seller  and  the
Shareholder,  no other party to any of the Contracts 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,  (c) no
Contract has been entered  into on terms which could  reasonably  be expected to
have an adverse effect on the use of the Assets by Buyer for the same purpose as
they were used by the Seller prior to the Closing  Date,  (d) neither the Seller
nor the Shareholder  has received any information  which would cause any of such
parties to conclude that any customer of the Seller will (or is likely to) cease
doing business with Buyer (or its successors) as a result of the consummation of
the transactions contemplated hereby.

2.1.4 Title to Assets. The Seller has good, indefeasible and marketable title to
all of the Assets, free and clear of any Encumbrances  (defined below) except as
set forth in Schedule 2.1.4 hereto.  Except as set forth in Schedule  1.1(a) and
Schedule  2.1.4  hereto,  all of the Assets  are (a) in a state of good  repair,
ordinary wear and tear  excepted,  (b) are free from any known defects except as
may be  repaired  by  routine  maintenance  and  such  minor  defects  as do not
substantially  interfere with the continued use thereof in the conduct of normal
operations and (c) to the knowledge of the Seller and the  Shareholder,  conform
to all applicable  laws  governing  their use. No notice of any violation of any
law,  statute,  ordinance or  regulation  relating to any of the Assets has been
received  by the  Seller or the  Shareholder,  except  such as have  been  fully

Plan and Trust, shall be paid by Seller and its shareholders and not by Key.

help or hinder the  profitable  conduct of the Business or the profitable use of
the Assets (or to assist the Seller in  connection  with any actual or  proposed
transaction) which if not given in the past, might have had an adverse effect on

claim  against  Buyer for a brokerage  commission,  finder's  fee or any similar
payment.

                                   ARTICLE III

                              Additional Agreements

3.1  Noncompetition.  Except as set forth below or as otherwise  consented to or

consultant,   representative,   advisor,   lender   (including  gifts  used  for
capitalization or collateral),  a holder of, or investor in as much as 3% of any
security of any class of any  corporation or other business entity (a) engage in
any business in  competition  with the business or  businesses  conducted by the

Buyer (or Buyer's affiliates) to terminate his or her employment. The Seller and
the Shareholder  agree that if either the length of time or geographical area as
set forth in this Section 3.1 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 3.1 are in addition
to any other  obligations  that the Seller or the Shareholder may have under the
laws of any state  requiring a corporation  selling its assets (or a shareholder
of such  corporation)  to limit its activities so that the goodwill and business
relations being  transferred  with such assets will not be materially  impaired.
The Seller and the Shareholder further agree and acknowledge that Buyer does not
have any  adequate  remedy  at law for the  breach or  threatened  breach by the
Seller or the  Shareholder  of the covenants  contained in this Section 3.1, and
agree that Buyer may, in addition to the other  remedies  which may be available
to it hereunder,  file a suit in equity to enjoin the Seller or the  Shareholder
from such breach or threatened breach. If any provisions of this Section 3.1 are
held to be invalid or against public policy, the remaining  provisions shall not
be  affected  thereby.  The  Seller  and the  Shareholder  acknowledge  that the
covenants set forth in this Section 3.1 are being executed and delivered by such
party  in  consideration  of (i)  the  covenants  of  Buyer  contained  in  this
Agreement,  (ii)  additional  consideration  in the amount of $10,000 payable by
Buyer to Seller and $10,000  payable by Buyer to  Shareholder on the date hereof

valuable   consideration,   the  receipt   and   adequacy  of  which  is  hereby
acknowledged.

of the Employees  actively engaged in the conduct of Seller's  business shall be
offered full or part-time employment by Buyer, subject to such Employees meeting
Buyer's standard employment eligibility requirements. Except as specifically set
forth as being  assumed  by Buyer on  Schedule 3.2  hereto  for those  Employees
actually  hired by Buyer,  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
Effective  Time. The Seller and the  Shareholder  shall  cooperate with Buyer in
connection  with any offer of  employment  from Buyer to the  Employees  and use
their best efforts to cause the acceptance of any and all such offers.

3.3  Allocation  of Purchase  Price.  The parties  hereto  agree to allocate the
Purchase  Price  payable  by Buyer  for the  Assets  hereunder  as set  forth on
Schedule 3.3 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

from the date of  Closing,  cause to be  filed  with the  Secretary  of State of
Colorado an amendment to the Articles of  Incorporation  of the Seller  changing
the names of the Seller from its  current  name to a name that is not similar to
such name. The Seller and the Shareholder  shall,  within five (5) days from the
date of its receipt of  confirmation of such filings from the Secretary of State

state in which the Seller is  qualified  to do  business  and deliver to Buyer a

would not be willing to complete the  transactions  contemplated  hereby without
such  representations,  warranties,  covenants and  agreements.  The Shareholder
acknowledges and agrees that he will personally  benefit from the  consideration
being paid by Buyer to Seller  hereunder and that such  consideration,  together

adequate  to  support  the  enforcement  of  their  representation,  warranties,
covenants and agreements contained herein.

3.7 Sublease Agreement.  Concurrently  herewith, the Buyer shall have executed a
Sublease  Agreement with Seller and  Shareholder,  pursuant to which Buyer shall

to be taken,  such further and other actions as may be  reasonably  necessary to
effect the transactions contemplated hereby.


                                   ARTICLE IV

                                 Indemnification

4.1 Indemnification by the Seller and the Shareholder.  In addition to any other
remedies  available to Buyer under this Agreement,  or at law or in equity,  the
Seller and the Shareholder shall, jointly and severally,  indemnify,  defend and
hold  harmless  Buyer  and  its  officers,  directors,   employees,  agents  and
stockholders (collectively,  the "Buyer Indemnified Parties"),  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")  which exceed the sum of $10,000 in the  aggregate  that a Buyer
Indemnified  Party shall incur or suffer  (whether  the damages are  suffered or
incurred  by such Buyer  Indemnified  Party  directly  or as a result of a third
party claim against such Buyer Indemnified  Party),  which arise, result from or
relate to (a) any breach of, or  failure  by the Seller and the  Shareholder  to
perform, their respective representations,  warranties,  covenants or agreements
in this Agreement or in any schedule,  certificate,  exhibit or other instrument
furnished  or  delivered  to Buyer by the Seller or the  Shareholder  under this
Agreement; or (b) the Retained Liabilities.

4.2 Indemnification by Buyer. In addition to any other remedies available to the
Seller or the Shareholder  under this Agreement,  or at law or in equity,  Buyer
shall  indemnify,  defend  and  hold  harmless  the  Seller  and  its  officers,
directors,  employees,  agents and stockholders and the Shareholder  against and
with  respect  to any and all  Damages  which  exceed  the sum of $10,000 in the
aggregate that such indemnitees shall incur or suffer,  which arise, result from
or relate to (a) any  breach  of, or  failure  by Buyer 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 the
Seller or the  Shareholder  by or on behalf of Buyer under this Agreement or (b)
the Assumed Liabilities.

4.3  Indemnification  Procedure.  If any party  hereto  discovers  or  otherwise
becomes  aware of an  indemnification  claim arising under Section 4.1 or 4.2 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 an indemnified  party to give notice as provided herein shall not
relieve the  indemnifying  party of any  obligation  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 third party  action or  proceeding  against such  indemnified  party with
respect  to  which a claim  for  indemnification  may be made  pursuant  to this
Article IV, 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 third party action; provided,  however, that the failure of
an  indemnified  party to give notice as provided  herein  shall not relieve the
indemnifying  party of any obligation  hereunder to the extent the  indemnifying
party is not materially  prejudiced thereby. In case any such third party 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 third party claim and to employ counsel
reasonably  satisfactory to such indemnified  person. An indemnifying  party who
elects not to assume the  defense of a third party 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 third
party  claim or with  respect to third  party  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 third party
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 third party
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 third party  claimant or plaintiff
to such  indemnified  party of a release from all liability with respect to such
third party claim.  No indemnified  party shall consent to entry of any judgment
or enter into any  settlement  of any such third  party  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, delayed or
continued.
