                                 PROPOSAL NO. 1
  SALE OF SUBSTANTIALLY ALL OF THE COMPANY'S PRODUCING OIL AND GAS PROPERTIES

     Description of Properties Proposed to be Sold.  The Company operates 12
wells in the Williston Basin of North Dakota and Montana.  Six of the wells are
located in the Smith Field, Renville County, North Dakota.  The Company's
working interests range from 70% to 100% in these wells which were drilled in
the late 1980's by TXO and were purchased by the Company from Marathon Oil
Company in 1992.  The Company has working interest ranging from 15% to 100% in
the other six wells.  The Company also owns interests in non-operated oil wells
located predominately in North Dakota, and Wyoming.  The Company has a 30.25%
working interest in the Antelope/Madison Unit in McKenzie County, North Dakota
which is the Company's largest producing property.  The field was discovered in
1956, and the Company purchased its interest in 1988 from Amoco Oil Company and
Exxon.  The Company has minor interests in Utah and Colorado and nine non-
operated properties in Wyoming.  It also has various royalty interests in
approximately 90 wells in the Powder River Basin of Wyoming which contribute on
average about 22 barrels of oil per day to the Company. These royalty interests
are also proposed to be sold.

     Certain reserve information, production history and cash flow concerning
the properties proposed to be sold is set forth below.

     Summary of Contract to Sell Properties.  The Company has entered into an
oil and gas purchase and sale agreement ("Agreement") to sell the above
properties.  A copy of the Agreement is on file at the offices of the Company
and may be inspected by shareholders during reasonable business hours.  The
following description of the Agreement is qualified in its entirety by reference
to the Agreement.

     Under the Agreement, there are four buyers of the interests to be sold
(collectively the  Buyer").  Two of the entities constituting the Buyer are not
affiliated with the Company, the other two persons are a corporation, owned by
the President of the Company, and an employee of the Company.  All of the
persons named below are engaged in the oil and gas business.  For information
concerning the Board of Directors' review of the transaction see  Fairness
Determination by the Board of Directors" below.

     The name and address of the parties constituting the Buyer, along with the
interest in the properties proposed to be purchased by each party, are as
follows:

<PAGE>
     Under the Agreement, all of the above described interests will be sold for
a total of $1,803,257 in cash.  The Buyer has deposited with the Company a
performance deposit of $180,325 applicable towards the price.  At the closing,
the Buyer will pay to the Company the remaining unpaid portion of the total
purchase price.  The Buyer has until April 30, 1997 to advise the Company in
writing of any title defects in the interests to be sold.  In the event of a
title defect, the Buyer may request reduction of the purchase price.  The
Company may request an increase in the purchase price if the net revenue
interests proposed to be sold are actually greater than that the Company
disclosed to the Buyer.  The parties agree to use their best efforts to agree on
the validity of any adverse claims to title and the amount of any purchase price
adjustment.  The Agreement also provides for applicable adjustment in price in
the event that a preferential right to purchase is exercised with respect to any
of the properties proposed to be sold.  The Company is unaware of any
preferential rights with respect to the properties proposed to be sold.
Conveyance of the interests of the Company will be without any warranty of title
and without any warranty of fitness or condition of the material or equipment
conveyed.

     The Agreement provides that the closing of the purchase and sale will be
held on or before July 1, 1997.  The Agreement further provides that all
proceeds from the sale of production by the Company prior to the effective time
of the property sale (January 1, 1997) and attributable to the interest shall
belong to the Company and all proceeds from the sale of production, less
operating expenses, attributable to the interest after such time shall belong to
the Buyer.  The Agreement provides that the Buyer shall have the right for 30
days to conduct or have conducted an environmental assessment of the properties
proposed to be sold and shall provide the results of such assessment to the
Company.  The Company is not aware of any environmental issues associated with
any of the properties to be sold.  Under the Agreement, the Company has made no
warranty or representation as to the quality or quantity of reserves
attributable to the interests to be sold.

     Fairness Determination by the Board of Directors.  The Board of Directors
of the Company, after a thorough review of the proposed transaction, believes
that the price to be received for the properties is fair and in the best
interest of the Company and its shareholders.

     For a considerable period of time, the Board of Directors has been
concerned that it is extremely difficult for a small, independent oil and gas
company to obtain exploration and development funds for expansion while
recognizing also that its assets were depleting.  Throughout 1996, the Board of
Directors considered several alternatives to enhance shareholder value,
including whether the Company should attempt to sell all of its oil and gas
properties and liquidate the Company, merge the Company with another oil entity
or sell the oil and gas properties and merge the Company with a non-oil related
entity.  None of these alternatives were chosen by the Board.

     In early December 1996, the Company received a bid from an outside third
party to purchase the properties proposed to be sold; the bid was approximately
$1,450,000.  The Board determined that this bid was not acceptable.  In January
1997 another entity made an offer of $1,725,000 for the properties proposed to
be sold.  The ultimate buyer then made an offer of $1,700,000.  Management of
the Company was directed to have bids resubmitted by the two parties.  On
January 19, 1997 the Company received bids from the two competing parties.  The
bid of All Energy, Inc. for $1,803,000 was the top bid.  The Board of Directors
reviewed the bid and determined that it was the highest and should be accepted.

     During the bidding process, the President of the Company, Tom N.
Richardson, along with an employee of the Company, requested to the Board that,
if acceptable to the purchaser, they be given the opportunity to purchase a
portion of the interests proposed to be sold.  To avoid conflicts, Mr.
Richardson and the employee of the Company did not participate in the bidding
process.  After the highest bid was accepted, the successful bidder, upon
request of the Company, determined that Mr. Richardson, through his entity,
Lifetime Associates, Inc., should be given the opportunity to purchase 10% of
the interests in the properties proposed to be sold and an employee, Douglas K.
Morton, should be given the opportunity to purchase 15% of the interests
proposed to be sold.  These amounts were agreed to after consultation between
the bidder and these two persons.  These persons will purchase their interests
on the same basis as the successful bidder for the properties.
<PAGE>
     The Board of Directors of the Company, after review of the bid proposals,
believes that the offer is fair to the Company.  The Board of Directors of the
Company made its determination without the input or advice of Mr. Richardson or
the employee who will be purchasing an interest.  The Board of Directors of the
Company collectively has spent many, many years in the oil and gas business in
evaluating oil and gas prospects and producing properties.  The Board reviewed
the production histories, cash flows and future potential for the properties, as
well as the Company's reserve report prepared for the Company by an independent
outside petroleum engineering firm.  The Board believes that under the present
circumstances, the price to be paid for the properties is fair to all
shareholders of the Company.  The Board of Directors made its determination
without the advice of an appraisal or so called  fairness opinion." However, the
Board is of the belief that its experience and abilities are superior to those
of outside advisors, particularly because of the Board's knowledge of the
properties proposed to be sold.

     In the event the proposal is approved by the shareholders at the Meeting,
the Board of Directors intends to review alternatives then available to the
Company, with the ultimate objective of obtaining the greatest shareholder value
possible.  These efforts could include, by way of illustration and not of
limitation, continuation of the Company's oil and gas business, attempting to
sell or merge the Company to another party or the liquidation or partial
liquidation of the Company.

     A partial liquidation might take the form, for example, of the Company
offering to redeem a portion of each shareholders' holdings in the Company.  The
Company, might then seek to merge with another company, more than likely a
private company wishing to have public shareholders and potential for a trading
market.  Any such partial liquidation or "self tender offer" would be made by
the Company only after complying with certain regulations adopted by the
Securities and Exchange Commission.

     These possible courses of action have only been generally reviewed by the
Board of Directors, and it will not undertake a definite course of action until
such time as the proposal is approved or rejected by the shareholders.  In the
event the proposal is rejected by the shareholders, the Board of Directors of
the Company intends to continue the business of the Company as well as evaluate
the different courses of action discussed above and attempt to maximize
shareholder value.  If the proposal is approved by shareholders, the Company
will attempt to minimize its general and administrative costs in order to
preserve as much cash as possible.  However, interest income from cash on hand
is not anticipated to cover such costs, although any losses incurred would not
be significant.  The Company is not aware of any federal or state regulatory
approvals relating to the proposal.

     Other than as described above there are no past, present or proposed
material contracts, arrangements, understandings, relationships, negotiations or
transactions between the persons constituting the Buyer and the Company.

     A VOTE FOR THIS PROPOSAL IS RECOMMENDED BY THE BOARD OF DIRECTORS.

The above reserve information for 1996 is based on estimates prepared by Allen &
Crouch, independent petroleum engineers, from data including ownership
interests, operating expenses, production information and current prices
furnished to them by the Company. Estimates of reserves for 1994 and 1995 were
prepared by the Company. Estimates of gas and oil reserves and their estimated
values require numerous engineering assumptions as to the productive capacity
and production rates of existing geological formations and require the use of
certain Securities and Exchange Commission guidelines as to assumptions
regarding costs to be incurred in developing and producing reserves and prices
to be realized from the sale of future production.  Revisions of previous year
estimates can have a significant impact on these values.  Also, exploration
costs in one year may lead to significant discoveries in later years and may
significantly changes previous estimates of proved reserves and their valuation.
Accordingly, estimates of reserves and their value are inherently imprecise and
are subject to constant revision and change and should not be construed as
representing the actual quantities of future production or cash flows to be
realized from the Company's gas and oil properties or the fair market value of
such properties.

The following is a standardized measure of the discounted net future cash flows
and changes applicable to proved oil and gas reserves required by the SFAS 69 of
the Financial Accounting Standards Board.  The future cash flows are based on
estimates of oil and gas reserves utilizing prices and costs in effect as of
year end discounted at 10% per year and assuming continuation of existing
economic conditions.

Standardized measure of discounted future net cash flows and changes therein
relating to proved oil and gas reserves at June 30:

                  NOTES TO PRO FORMA STATEMENTS OF OPERATIONS

(1)  Adjustments to eliminate all revenue and expenses pertaining to oil and gas
     operations.

(2)  Adjustments to eliminate sale of investments that relate to hedging
     transactions for oil and gas production units.

(3)  Adjustments to reflect that the proceeds for the sale of the properties and
     other cash will be invested in U.S. Treasury bills and earn a minimum rate
     of return of 4.5%.

(4)  Elimination of earnings on a coal partnership to be sold.

(5)  Elimination of interest expense as if sale had occurred at July 1, 1995.
     All long-term debt would have been paid as of that time.

(6)  Reduction of general and administrative expenses to reflect that, without
     oil and gas operations, the Company would have need for only one employee.
     Other expenses such as telephone, legal, accounting, dues, etc. would have
     been substantially lower.

(7)  Valuation allowance will remain on deferred tax asset.  Past evidence does
     not prove it is "more likely than not" to be realized.

        RIGHTS OF DISSENTING SHAREHOLDERS TO RECEIVE PAYMENT FOR SHARES

     The following is a summary of dissenters' rights available to shareholders
of the Company, which summary is not intended to be a complete statement of
applicable Wyoming law and is qualified in its entirety by reference to Article
13 of the Wyoming Business Corporation Act, which is set forth as Appendix A
hereto.

     Procedure for Exercise of Dissenters' Rights.  A shareholder who wishes to
assert dissenters' rights shall deliver to the Company before the vote is taken
at the Meeting a written notice of his or her intent to demand payment for his
or her shares if the proposal is effectuated.  Furthermore, such shareholder may
not vote his or her shares in favor of the proposed action.  A shareholder who
does not satisfy these requirements shall not be entitled to payment for shares
under the Wyoming Business Corporation Act.

     In the event the proposal is approved at the Meeting, the Company will
deliver a written dissenters' notice to all shareholders who provided a proper
notice of intent to demand payment to the Company.  The letter shall be sent no
later than 10 days after the action was taken and shall:  (i) state where the
payment demand shall be sent and where and when certificates for certificated
shares shall be deposited; (ii) inform holders of uncertificated shares to what
extent the transfer the shares will be restricted after the payment demand is
received; (iii) supply a form for demanding payment that includes the date of
the first announcement to news media or to shareholders of the terms of the
proposed corporate action and require that the person asserting dissenters'
rights certify whether or not he or she acquired beneficial ownership of the
shares before that date; (iv) set a date by which the Company shall receive the
payment demand, which date may not be fewer than 30 nor more than 60 days after
the date the notice is delivered; and (v) be accompanied by a copy of Article 13
of the Wyoming Business Corporation Act.
<PAGE>
     A shareholder who receives a notice from the Company shall demand payment,
certify whether he or she acquired beneficial ownership of the shares before the
date required to be set forth in the dissenters' notice and deposit his or her
shares in accordance with the terms of the notice of the Company.  A shareholder
who demands payment and deposits his share certificates shall retain all other
rights of a shareholder until such rights are canceled or modified by the taking
of the proposed corporate action.  A shareholder who does not demand payment or
deposit his or her share certificates where required, each by the date set in
the notice given by the Company, shall not be entitled to payment for his or her
shares under the Wyoming Business Corporation Act.  The Company may restrict the
transfer of uncertificated shares from the date the demand for payment is
received until the proposed corporate action is taken.

     As soon as the proposed corporate action is taken, or upon receipt of a
payment demand, the Company will pay each dissenter who complies with the above
provisions the amount the Company estimates to be the fair value of his or her
shares plus accrued interest.  The payment shall be accompanied by the
Company's:  (i) balance sheet as of September 30, 1996, income statement for
that fiscal year, statement of changes in shareholders' equity for that fiscal
year and the latest available interim financial statements; (ii) a statement of
the Company's estimate of the fair value of the shares; (iii) an explanation of
how interest was calculated; (iv) a statement of the dissenters' right to demand
payment and a copy of Article 13 of the Wyoming Business Corporation Act.

     If the Company does not take the proposed action within 60 days after the
date set for demanding payment and depositing share certificates, the Company
will return the deposited certificates and release the transfer restrictions
imposed on uncertificated shares.  If, after returning deposited certificates
and releasing transfer restrictions, the Company takes the proposed action, it
will send a new dissenters' notice and repeat the payment demand procedure.

     The Company may elect to withhold required payment to dissenters unless
such dissenters were the beneficial owners of the shares before the date set
forth in the dissenters' notice as of the date of the first announcement to news
media or to shareholders of the terms of the proposed corporate action.  To the
extent the Company elects to withhold payment after taking the proposed
corporate action, it will estimate the fair value of the shares plus accrued
interest and will pay this amount to each dissenter who agrees to accept it in
full satisfaction of his or her demand.  The Company will send with its offer a
statement of its estimate of the fair value of the shares, an explanation of how
interest was calculated, and  a statement of the dissenter's right to demand
payment if the shareholder is dissatisfied with the payment or offer.

     A dissenter may notify the Company in writing of his or her own estimate of
the fair value of his or her shares and the amount of interest due, and demand
payment of such estimate less any prior payments made or reject the offer of the
Company and demand payment of the fair value of his or her shares and interest
due if:  (i) the dissenter believes that the amount or offered is less than the
fair value of his or her shares or that the interest due is incorrectly
calculated; (ii) the Company fails to make payment within 60 days after the date
set for demanding payment; or (iii) the Company, having failed to take the
proposed action, does not return the deposited certificates or release the
transfer restrictions imposed on uncertificated shares within 60 days after the
date set for demanding payment.  A dissenter waives his or her right to demand
payment under this procedure unless he or she notifies the Company of his or her
demand in writing within 30 days after the Company made or offered payment for
his or her shares.

     Judicial Appraisal of Shares.  If a demand for payment remains unsettled,
the Company will commence a proceeding within 60 days after receiving the
payment demand and petition a court to determine the fair value of the shares
and accrued interest.  If the Company does not commence the proceeding within
the 60 day period, it shall pay each dissenter whose demand remains unsettled,
the amount demanded.  The Company will commence any such proceeding in the
District Court of Natrona County, Wyoming.  The Company will make all dissenters
whose demand remains unsettled parties to the proceeding as in a action against
their shares and all parties will be served with a copy of the petition.  The
court may appoint one or more persons as appraisers to receive evidence and
recommend decision on the question of fair value.  The appraisers will have the
powers described in the order appointing them.  The dissenters will be entitled
to the same discovery rights in the court action as parties in other civil
proceedings.
<PAGE>
     Each dissenter made a party to the proceeding will be entitled to judgment
for:  (i) the amount, if any, by which the court finds the fair value of shares,
plus interest, exceeds the amount paid by the Company; or (ii) the fair value,
plus accrued interest, of after acquired shares for which the Company elected to
withhold payment.

     The court in an appraisal proceeding will determine all costs of the
proceeding, including the reasonable compensation and expenses of court
appointed appraisers.  The court will assess the costs against the Company,
except that the court may assess costs against all or some of the dissenters, in
amounts the court finds equitable, to the extent the court finds the dissenters
acted arbitrarily, vexatiously or not in good faith in demanding payment.  The
court may also assess the fees and expenses of counsel and experts for the
respective parties, in amounts the court finds equitable:  (i) against the
Company and in favor of any or all dissenters if the court finds the Company did
not comply substantially with the requirements of Article 13 of the Wyoming
Business Corporation Act; or (ii) against either the Company or a dissenter, in
favor of any other party, if the court finds that the party against whom the
fees and expenses are assessed acted arbitrarily, vexatiously or not in good
faith with respect to the rights provided in Article 13 of the Wyoming Business
Corporation Act.  If the court finds that the services of counsel for any
dissenter were of substantial benefit to other dissenters similarly situated,
and that the fees for those services should not be assessed against the Company,
the court may award to such counsel reasonable fees to be paid out of the
amounts awarded the dissenters who would benefit.

                                 OTHER MATTERS
     The Board of Directors knows of no other matters to be brought before the
Meeting; if other matters properly come before the Meeting, it is the intention
of the persons named in the solicited proxy to vote such proxy in accordance
with their judgment.

     No compensation will be paid to any person in connection with solicitation
of proxies.  Brokers, banks, and other entities will be reimbursed for out-of-
pocket and reasonable clericals expenses incurred in obtaining instructions from
beneficial owners of the Company's Common stock.  Special solicitation of
proxies may, in certain instances, be made personally or by telephone by
officers and employees of the Company and by employees of certain banking and
brokerage houses.  All expenses, estimated to be normal in connection with this
solicitation, will be borne by the Company.

     Representatives of the Company s independent accountants, Hocker, Lovelett,
Hargens & Skogen, P.C., are expected to be present at the Meeting and will have
the opportunity make a statement if they desire to do so and will be available
to respond to appropriate questions.

                  DEADLINE OF RECEIPT OF SHAREHOLDER PROPOSALS
            FOR ANNUAL MEETING SCHEDULED TO BE HELD IN DECEMBER 1997

     Any proposal by a shareholder to be presented at the Company's Annual
Meeting of Shareholders scheduled to be held in December 1997 must be received
at the offices of the Company, Suite 101, 777 North Overland Trail, Casper,
Wyoming  82601, no later than August 1, 1997.

     (i)  Consummation of a plan of merger or consolidation to which the
corporation is a party if:

extent the articles of incorporation, bylaws, or a resolution of the board of
directors provides that voting or nonvoting shareholders are entitled to dissent
and obtain payment for their shares.
     (b)  A shareholder entitled to dissent and obtain payment for his shares
under this article may not challenge the corporate action creating his

shareholder or the corporation.

     17-16-1303 DISSENT BY NOMINEES AND BENEFICIAL OWNERS.-(a) A record

rights.  The rights of a partial dissenter under this subsection are determined
as if the shares as to which he dissents and his other shares were registered in
the names of different shareholders.
     (b)  A beneficial shareholder may assert dissenters' rights as to shares
held on his behalf only if:
     (i)  He submits to the corporation the record shareholder's written consent
to the dissent not later than the time the beneficial shareholder asserts
dissenters' rights; and
     (ii) He does so with respect to all shares of which he is the beneficial

the terms of the proposed corporate action.
     (b)  To the extent the corporation elects to withhold payment under
subsection (a) of this section, after taking the proposed corporate action, it
shall estimate the fair value of the shares, plus accrued interest, and shall
pay this amount to each dissenter who agrees to accept it in full satisfaction
of his demand.  The corporation shall send with its offer a statement of its
estimate of the fair value of the shares, an explanation of how the interest was

     17-16-1328 PROCEDURE IF SHAREHOLDER DISSATISFIED WITH PAYMENT OR OFFER.-(a)
A dissenter may notify the corporation in writing of his own estimate of the
fair value of his shares and amount of interest due, and demand payment of his
estimate, less any payment under W.S. 17-16-1325, or reject the corporation's
offer under W.S. 17-16-1327 and demand payment of the fair value of his shares
and interest due, if:
     (i)  The dissenter believes that the amount paid under W.S. 17-16-1325 or
offered under W.S. 17-16-1327 is less than the fair value of his shares or that
the interest due is incorrectly calculated;
     (ii) The corporation fails to make payment under W.S. 17-16-1325 within
sixty (60) days after the date set for demanding payment; or
     (iii)     The corporation, having failed to take the proposed action, does
not return the deposited certificates or release the transfer restrictions
imposed on uncertificated shares within sixty (60) days after the date set for
demanding payment.
     (b)  A dissenter waives his right to demand payment under this section
unless he notifies the corporation of his demand in writing under subsection (a)
of this section within thirty (30) days after the corporation made or offered
payment for his shares.

                  Subarticle C.  Judicial Appraisal of Shares

     17-16-1330 COURT ACTION.-(a) If a demand for payment under W.S. 17-16-1328
remains unsettled, the corporation shall commence a proceeding within sixty (60)
days after receiving the payment demand and petition the court to determine the
fair value of the shares and accrued interest.  If the corporation does not
commence the proceeding within the sixty (60) day period, it shall pay each
dissenter whose demand remains unsettled the amount demanded.
     (b)  The corporation shall commence the proceeding in the district court of
the county where a corporation's principal office, or if none in this state, its
registered office, is located.  If the corporation is a foreign corporation
without a registered office in this state, it shall commence the proceeding in
the county in this state where the registered office of the domestic corporation
merged with or whose shares were acquired by the foreign corporation was
located.
<PAGE>
     (c)  The corporation shall make all dissenters, whether or not residents of
this state, whose demands remain unsettled parties to the proceeding as in an
action against their shares and all parties shall be served with a copy of the
petition.  Nonresidents may be served by registered or certified mail or by
publication as provided by law.
     (d)  The jurisdiction of the court in which the proceeding is commenced
under subsection (b) of this section is plenary and exclusive.  The court may
appoint one (1) or more persons as appraisers to receive evidence and recommend
decision on the question of fair value.  The appraisers have the powers
described in the order appointing them, or in the amendment to it.  The
dissenters are entitled to the same discovery rights as parties in other civil
proceedings.
     (e)  Each dissenter made a party to the proceeding is entitled to judgment
for:
     (i)  The amount, if any, by which the court finds the fair value of his
shares, plus interest, exceeds the amount paid by the corporation; or
     (ii) The fair value, plus accrued interest, of his after-acquired shares
for which the corporation elected to withhold payment under W.S. 17-16-1327.

     17-16-1331 COURT COSTS AND COUNSEL FEES.-(a) The court in an appraisal
proceeding commenced under W.S. 17-16-1330 shall determine all costs of the
proceeding, including the reasonable compensation and expenses of appraisers
appointed by the court.  The court shall assess the costs against the
corporation, except that the court may assess costs against all or some of the
dissenters, in amounts the court finds equitable, to the extent the court finds
the dissenters acted arbitrarily, vexatiously, or not in good faith in demanding
payment under W.S. 17-16-1328.
     (b)  The court may also assess the fees and expenses of counsel and experts
for the respective parties, in amounts the court finds equitable:
     (i)  Against the corporation and in favor of any or all dissenters if the
court finds the corporation did not substantially comply with the requirements
of W.S. 17-16-1320 through 17-16-1328; or
     (ii) Against either the corporation or a dissenter, in favor of any other
party, if the court finds that the party against whom the fees and expenses are
assessed acted arbitrarily, vexatiously, or not in good faith with respect to
the rights provided by this article.
     (c)  If the court finds that the services of counsel for any dissenter were
of substantial benefit to other dissenters similarly situated, and that the fees
for those services should not be assessed against the corporation, the court may
award to these counsel reasonable fees to be paid out of the amounts awarded the
dissenters who were benefitted.

                         AGREEMENT TO PURCHASE AND SELL

     THIS AGREEMENT, made and entered into by and between TYREX OIL COMPANY, a
Wyoming Corporation, with address of P. O. Box 2459, Casper, Wyoming 82602,
hereinafter called "Tyrex", as Seller, and All Energy, Inc., P.O. Box 3439,
Casper, Wyoming 82602, a Wyoming Corporation, 60% interest, Steve C. Kirkwood,
1715 Brookview Drive, Casper, WY 82601, 15% interest, Douglas K. Morton, 2001
Begonia Casper, WY 82604, 15% interest, and Lifetime Associates, Inc., a Wyoming
Corporation, 116 Valley Drive Casper, WY 82604, 10% interest, hereinafter
collectively called "Buyer", and effective as of the date signed by Tyrex.


                                   WITNESSETH

     Pursuant to an offer submitted by Buyer, Tyrex agrees to sell to Buyer and
Buyer agrees to buy from Tyrex as of the Effective Time (as hereinafter
defined), for the consideration recited and subject to the terms and conditions
set forth, all of Tyrex's interest in those certain oil and gas leasehold
estates or other interests set forth in Exhibit A, and the material and
equipment therein and thereon and used in connection with the operation of said
property for oil and/or gas purposes, including, but not limited to all well
bores, well heads, downhole equipment, casing and tubing, specifically excluding
vehicles, boats, tools, pulling machines, warehouse stock, equipment or material
temporarily located on the properties, and any equipment, pipelines, fixtures or
interests in land owned by any purchaser and/or transporter of oil and/or gas
from the properties (all of the interests, material and equipment being sold by
Tyrex are referred to hereafter as "Interests").

                                   ARTICLE 1

     Buyer agrees to pay for the Interests the total sum of $1,803,257.00 in
cash, subject only to any price adjustments, as set forth herein. As evidence of
good faith, Buyer has deposited or will deposit with Tyrex a performance deposit
of $180,325.00, applicable to the above unadjusted purchase price, which deposit
is to be non-interest bearing and which is non-refundable except as provided
subsequently. At Closing (as hereinafter defined), Buyer shall pay and deliver
to Tyrex the remaining unpaid portion of the total purchase price after any
applicable price adjustment as provided for herein. Within five business days
after receipt from Tyrex of a document for such purposes, Buyer shall provide an
allocation of the purchase price to each individual property (including an
allocation between leasehold and equipment) listed on such document for the
purpose of (i) establishing a basis for certain taxes, (ii) obtaining waivers of
any preferential rights to purchase the property, and (iii) handling those
instances for which the purchase price is adjusted as provided herein. In the
event that a negative allocation is made on any property, Tyrex expressly
reserves the right to withdraw such property or properties from sale, and Buyer
agrees to increase the purchase price by the same dollar amount allocated to
these properties. For purposes of this Agreement, the parties hereto agree that
the purchase price will be allocated as $1,097,169 for Equipment and $706,088
for Reserves.
<PAGE>


                                   ARTICLE 2

     Promptly after execution of this Agreement by both parties, Tyrex shall
endeavor to provide Buyer and Buyer's authorized representatives, at any
reasonable time(s) before Closing (i) physical access to the wells and other
equipment included in Tyrex operated interests and associated facilities and
properties, at Buyer's sole risk, cost and expense, for the purpose of
inspecting the same, and (ii) access, with copying privileges, at Buyer's sole
cost, to all raw geological, production, engineering, environmental, and other
technical data and records, and to all contract, land, lease, and permit
records, to the extent such data and records are in Tyrex's possession and
relate to the Interests; provided, however, Tyrex shall have no obligation to
provide Buyer access to any interpretative or predictive data or information
which Tyrex considers confidential to it or which access Tyrex cannot lawfully
provide Buyer because of third-party restrictions on Tyrex.


                                   ARTICLE 3

     Within forty-five (45) days from the effective date of this Agreement,
Buyer shall advise Tyrex in writing of any Title Defects in the Interests. For
the purpose of this Agreement, a "Title Defect" shall mean a material deficiency
in one (or more) of the following respects, to-wit:

          (a)  Tyrex's title at the Effective Time, as to one or more
          properties, is subject to an outstanding mortgage, deed of trust, lien
          or encumbrance or other adverse claim not mentioned on Exhibit A which
          would induce a pipeline purchaser to suspend payment of proceeds as to
          Tyrex's interest or require the furnishing of security or indemnity.
          Evidence that Tyrex is currently receiving its full share of proceeds
          from a pipeline purchaser or third-party operator (not under a 100% or
          other division order requiring Tyrex to further distribute proceeds to
          third parties) for the Tyrex interest shown on Exhibit A shall be
          considered a presumption that no defect exists with respect to that
          interest;

          (b)  Tyrex own less than the net revenue interest shown on Exhibit A
          for a property;
<PAGE>
          (c)  Tyrex's rights and interests are subject to being reduced by
          virtue of the exercise by a third party of a reversionary, back-in or
          other similar right not reflected in the Bid Package, Exhibit A or any
          supplemental letters and/or addendum sent to Bidders;
          (d)  Tyrex is in default under some material provision of a lease,
          farmout agreement, or other contract or agreement affecting the
          Interests.

Loss of any lease acreage between the effective date of this Agreement and
Closing due to expiration of the lease term will not constitute a Title Defect.


                                   ARTICLE 4

     Buyer may, by delivery of written notice to Tyrex of the existence of a
Title Defect, request reduction of the purchase price. Tyrex may request an
increase in the purchase price by delivery to Buyer of written notice that the
net revenue interest actually owned by Tyrex therein is greater than that shown
on Exhibit A for a property.

     Any such notice by Buyer or Tyrex shall include appropriate documentation
to substantiate its position and shall be delivered to the other party within 45
days after the effective date of this Agreement. In the event any such notice is
not timely delivered, the claimant shall thereafter have no right to assert such
Title Defect or different revenue interest as the basis for an adjustment in the
purchase price.

     Upon timely delivery of a notice either by Buyer of a Title Defect or by
Tyrex of an increase in a net revenue interest, Buyer and Tyrex shall meet and
use their best efforts to agree on the validity of the claim and the amount of
any required purchase price adjustment. If the parties cannot agree on the
amount of a price adjustment, such amount shall be determined in accordance with
the following guidelines:

          (a)  If a Title Defect is based upon Buyer's notice that Tyrex owns a
          lesser net revenue interest, or the notice is from Tyrex to the effect
          that Tyrex owns a greater net revenue interest than that shown on
          Exhibit A hereto, then the portion of the purchase price allocated to
          the affected property shall be reduced or increased (as the case may
          be ) by an amount that is 90% of the amount obtained by multiplying
          the ratio of the actual net revenue interest to the net revenue
          interest shown on Exhibit A by the purchase price allocated to the
          affected property.
<PAGE>
          (b)  If a Title Defect is a lien, encumbrance or other charge upon a
          property which is liquidated in amount, then the adjustment shall be
          the sum necessary to be paid to the obligee to remove the Title Defect
          from the affected property. If a Title Defect represents an obligation
          or burden upon the affected property for which the economic detriment
          to Buyer is not liquidated but can be estimated with reasonable
          certainty, the adjustment shall be the sum necessary to compensate
          Buyer at Closing for the adverse economic effect which such Title
          Defect will have on the affected property. If there is a lien or
          encumbrance in the form of a judgment secured by a supersedeas bond or
          other security approved by the Court issuing such order, it shall not
          be considered a Title Defect under this Agreement.

     Buyer may only adjust the purchase price for Title Defects at Closing if
the cumulative amount of adjustments in its favor exceeds $1,000.00. Similarly,
Tyrex may only adjust the purchase price at Closing if the cumulative amount of
adjustments in its favor exceeds $1,000.00. In the event the net amount of the
purchase price adjustments downward exceed 10% of the purchase price, then Tyrex
may, upon written notice to Buyer, cancel this Agreement and the same shall be
of no further force and effect. In such event Tyrex shall return the performance
deposit to Buyer.

     If Buyer shall receive an adjustment of the purchase price at Closing on
account of a Title Defect, Tyrex shall have 90 days after Closing to cure such
Title Defect at its cost. If on or before such date, Tyrex can demonstrate to
Buyer's reasonable satisfaction that such Title Defect has been cured, then
Buyer shall pay Tyrex the amount of the adjustment received by Buyer at Closing
as a result of such Title Defect. Buyer shall pay such amount to Tyrex within
ten (10) business days after receipt of the notice that the Title Defect has
been cured.

     If Tyrex determines prior to Closing or within sixty (60) days after
Closing that a property description is incorrect, or certain properties or
particular interests in a given property or certain gas imbalances among working
interest owners included in the bid package were included in error and are not
intended for sale, then Tyrex and Buyer shall meet and use their best efforts to
resolve the error. Should Tyrex and Buyer be unable to resolve an error prior to
Closing, then Tyrex will refund the performance deposit and neither Tyrex or
Buyer will have any further obligations under this Agreement. Should Tyrex and
Buyer be unable to resolve an error discovered within sixty (60) days after
Closing, then Buyer, upon written demand by Tyrex, will make a full reassignment
to Tyrex of the Interests, or such gas imbalances purchased, upon the same terms
and conditions as set forth in the assignments conveying the Interests, or gas
imbalance, to Buyer and Tyrex will refund to Buyer the full purchase price
without incurring any interest or any other obligations on Tyrex's part. Any oil
and gas lease entered into between Tyrex and Buyer in accordance with this
Agreement shall terminate in such event and be of no force and effect.

<PAGE>
                                   ARTICLE 5
     In the event a third party exercises an applicable preferential right to
purchase any of the properties, the purchase price shall be adjusted by the
dollar amount Buyer allocated to the affected property regardless whether it is
greater or less than zero and Closing shall occur as to the remainder of the
properties. Should a third party exercise such preferential right to purchase a
property to which Buyer has allocated a negative dollar amount, Buyer agrees to
increase the total purchase price by a dollar amount equal to the negative price
allocation. Should a third party exercise such preferential right to purchase a
property to which Buyer has allocated a positive dollar amount, Tyrex agrees to
reduce the total purchase price by a dollar amount equal to the positive price
allocation.


                                   ARTICLE 6

     At Closing, Tyrex shall execute a conveyance in favor of Buyer covering the
Interests on Tyrex's usual and customary Form of Transfer and Conveyance or
Assignment and Bill of Sale, attached as Exhibit "B", WITHOUT ANY WARRANTY OF
TITLE WHATSOEVER, EITHER EXPRESSED OR IMPLIED AND WITHOUT ANY WARRANTY OF
FITNESS OR CONDITION OF THE MATERIAL OR EQUIPMENT CONVEYED. Any conveyance
executed pursuant to these premises shall be effective as of 7:00 am MST January
1, 1997 (the "Effective Time") regardless of when Closing may actually occur.


                                   ARTICLE 7

     The Closing shall be held on or before May 1, 1997, at 9:00 a.m. MST, at
the offices of Tyrex at 777 N. Overland Trail, Suite 101, Casper, WY, or at such
other place as Tyrex may designate, or at such other time and place to which
Tyrex and Buyer may mutually agree in writing. At Closing the following will
occur:
          (a)  Buyer shall deliver to Tyrex a certificate, in form satisfactory
          to Tyrex, dated as of the Closing and executed by a duly authorized
          officer, partner, or owner, as appropriate, of Buyer, to the effect
          that Buyer has all requisite corporate, partnership or other power and
          authority to purchase the Interests on the terms described in this
          Agreement and to perform its other obligations hereunder and that all
          corporate, partnership and/or other prerequisites of whatsoever nature
          have been fulfilled.
<PAGE>
          (b)  Tyrex shall execute, acknowledge and deliver assignments, bills
          of sales and such other instruments as may be necessary to convey
          title to the interests to Buyer.

          (c)  Buyer shall deliver to Tyrex by wire transfer of cash, or
          certified funds, the remaining balance of the total purchase price as
          adjusted hereunder, subject to further adjustment after Closing as
          provided for herein.

          (d)  Tyrex at its sole option may provide a preliminary settlement
          statement covering ad valorem taxes, severance taxes, crude
          inventories above the pipeline connection, and gas production
          inventories credited to Tyrex as of the effective date. Tyrex may also
          provide an estimate of operating expenses and capital expenditures
          from the Effective Time until the time of final settlement. If such
          preliminary settlement and/or estimates are provided, Tyrex may
          require payment of this preliminary settlement at Closing.

          (e)  For Interests in the states of Montana and North Dakota, Buyer
          shall deliver to Tyrex, at or prior to Closing, evidence of the
          appropriate bond, surety letter or letter of credit in a form
          acceptable to the relevant State regulatory agency.
          (f)  Tyrex shall provide Buyer copies of executed documents on all
          wells (inactive or active) operated by Tyrex, as required by the
          applicable regulatory agency to effect a change of operator for the
          properties being sold. These documents shall be approved and endorsed,
          if necessary, by the applicable regulatory agency accepting the Buyer
          as the new operator. Should Tyrex and Buyer fail to close for any
          reason after such document designating Buyer as the operator has been
          approved, Buyer agrees to provide documentation to re-designate Tyrex
          as the operator of the leases and wells within three (3) days after
          receipt of Tyrex's request in writing.

          (g)  Tyrex shall (subject to the terms of any applicable operating
          agreements and to the other provisions hereof) deliver to Buyer
          exclusive possession of the Interests, effective as of the Effective
          Time.

          (h)  Within thirty (30) days after Closing, Tyrex will furnish Buyer
          originals or copies of data and records identified in Article 2 (ii).

     After the Closing, Tyrex shall prepare the conveyancing documents for the
appropriate governmental records, and shall provide a certified copy of same to
the Buyer. Buyer will record and pay for all fees associated with the recording
of these documents.

turned over to, and become the responsibility of, Buyer. The risk of casualty
loss relating to the Interests shall pass from Tyrex to Buyer as of the
Effective Time. In the event Closing occurs after the Effective Time, or an
applicable operating agreement otherwise requires, Tyrex shall, unless Buyer and

Closing or such later time as any applicable operating agreement may require;
provided, however, that such operation from and after the Effective Time shall
be conducted by Tyrex for and on behalf of Buyer and Buyer shall pay Tyrex for

Buyer as of the Effective Time. Buyer shall reimburse Tyrex for any costs
invoiced by operator and paid by Tyrex for the operation of such Interests after

or pertain to the Interests and to execute any documents necessary to effectuate
such agreement. The parties agree that this Article shall apply to any and all
instruments whether they are recorded or unrecorded.

     Buyer further recognizes that the sale of the above described Interests may
require the approval of the lessors, joint interest partners, farmors,
sublessors, assignors or any governmental body having jurisdiction and Buyer
agrees to assume full responsibility for obtaining any such consent and approval
from the above-mentioned parties and furnishing Tyrex with proof of such consent
and approval. Buyer further acknowledges that Tyrex shall attempt to obtain
waivers from the owners of any preferential rights to purchase properties. Buyer

     Buyer agrees to defend, indemnify and hold Tyrex harmless from any claims,
causes of actions or lawsuits which may arise on or after the Effective Time

identified herein and are the subject of this Agreement including claims, causes
of actions or lawsuits asserted by third parties or persons holding rights under
any mineral lease subject to this sale, for death, injury, damage to property,
or failure to comply with the express or implied terms of a mineral lease, and
further including any claims, causes of actions or lawsuits asserted by the
state, federal or local government or any agency or body thereof, specifically
including, without limitations, any expenses arising out of, or in connection
with, the plugging and abandoning of any wells. Buyer's indemnification of Tyrex
shall extend to and include claims, causes of action or lawsuits based on
Tyrex's negligence in operating any of the Interests from and after the
Effective Time but shall not extend to any gross negligence or willful
misconduct of Tyrex during that same period.


                                   ARTICLE 19

     The properties which have been identified herein and are the subject of
this Agreement have been utilized by Tyrex for the purpose of exploration,
development, and production of oil and gas. Information, to the best of Tyrex's
knowledge, regarding solid waste, including crude oil and produced water, which
may have been spilled or disposed of on-site and the locations thereof,
including pit closures, burial, landfarming, landspreading, and underground
injection will be made available to Buyer prior to Closing. Buyer acknowledges
that there may have been spills of these materials in the past onto the
properties described herein. In addition, some oil field production equipment
may contain asbestos and/or Naturally Occurring Radioactive Material
(hereinafter referred to as "NORM"). In this regard, Buyer expressly understands
that NORM may affix or attach itself to the inside of wells, materials and
equipment as scale, or in other forms, and that said wells, materials and
equipment located on the property described herein may contain NORM and that
NORM-containing material may be buried or otherwise disposed of on the
properties. Buyer also expressly understands that special procedures may be
required for the removal and disposal of asbestos and NORM from the equipment
and properties where it may be found and that Buyer assumes all liability when
such activities are performed.
<PAGE>
     Promptly after execution of this Agreement by both parties, Buyer shall
have the right for 30 days, at its own risk and expense, to conduct or have
conducted an environmental assessment of the described properties and shall
provide the results of the environmental assessment to Tyrex. Tyrex will provide
Buyer (or its contractor) with reasonable access to the properties operated by
Tyrex to conduct the environmental assessment. Tyrex may require Buyer or its
contractor to comply with Tyrex's safety and industrial hygiene procedures.
Buyer shall release and indemnify and hold harmless Tyrex against any liability
or damage to persons or property arising out of such environmental assessment.
Such indemnity shall also apply where the liability or damage arises in whole or
in part from the negligence of Tyrex. Within this 30 day period, Buyer shall
advise Tyrex of any material adverse environmental conditions of the properties
which it finds unacceptable. For the purpose of this paragraph, such conditions
shall be "material" only if they will cost in excess of .2% of the total
purchase price to cure or remedy and were not disclosed on or before the
execution of this Agreement. Within 30 days after receipt of such notice, Tyrex
may either (1) remedy or agree to remedy such material objection, (2) agree with
Buyer on an adjustment to the purchase price or (3) remove the property or
properties from the interests being conveyed and adjust the purchase price
accordingly. BUYER UNDERSTANDS AND AGREES THAT THIS SALE IS MADE ON AN "AS IS,
WHERE IS" BASIS AND BUYER RELEASES TYREX FROM ANY LIABILITY WITH RESPECT THERETO
WHETHER OR NOT CAUSED BY OR ATTRIBUTABLE TO TYREX'S NEGLIGENCE EXCEPT AS
OTHERWISE EXPRESSLY AGREED UPON IN WRITING BY TYREX.

     Buyer shall dispose of or discharge any of its waste (including but not
limited to produced water, drilling fluids and other associated wastes) in
accordance with applicable local, state and federal regulations. To the extent
that the properties are not sold in fee to Buyer, Buyer shall keep records of
the types, amounts and location of wastes of which are disposed onsite and
offsite. When and if any lease, an interest in which has been assigned
hereunder, is terminated, Buyer shall take whatever remedial action on the
properties is necessary to meet any local, state or federal requirements
directed at protecting human health and the environment in effect at that time.

     Buyer, its successors and assigns, hereby agrees to indemnify and defend
Tyrex, its successors and assigns, from and against all claims, demands, and

including (without limitation) Buyer's and Tyrex's employees, agents, or
representatives and also including (without limitation) any private citizens,
persons, organizations, and any agency, branch, or representative of federal,

soil, surface water or ground water) resulting from or arising out of any
liability caused by or connected with the presence, disposal or release of any
material of any kind in or under the land at the time it is effectively conveyed
to Buyer, or thereafter caused by acts of Buyer, its agents, employees,
representatives, or agents with regard to its use of the described properties
subsequent to the conveyance of the described properties pursuant to this
Agreement without regard to any claimed negligence, active or passive, on the
part of Tyrex. This indemnification shall be in addition to any other indemnity
provisions contained in this Agreement, and it is expressly understood and
agreed that any terms of this Article shall control over any conflicting or

Article.

cease receiving revenue and incurring operating expenses for the properties
being conveyed. Generally, sixty (60) days following Closing, Tyrex will review

overhead as provided for in Articles 14 and 15 herein. Approximately sixty (60)
days after Closing, or at such other date as Buyer and Tyrex shall mutually
agree, Tyrex shall issue a "final settlement statement" for each property
conveyed. This statement will net revenues received against royalties, operating
expenses, taxes, and overhead (if applicable). The final settlement statements
will be summarized and a net check or invoice will be sent to the Buyer. Buyer

Re:   Closing date for Purchase and Sale
      Tyrex Oil Company Properties

Dear Tom:

As per our conversation, please let this letter serve as an amendment to the
Purchase and Sell Agreement which provides in Article 7 on page 5 of the
agreement for a closing date of on or before May 1, 1997 at 9:00 a.m. MST. It is
hereby agreed to that the closing date shall be changed to on or before July 1,
1997 at 9:00 a.m. local time.

The additional time will allow for Tyrex to receive the necessary approvals from
the SEC and its shareholders, as well as allow for the snow to melt before the
Phase 1 environmental audit begins.

Please so indicate your acceptance by signing and returning one copy of this
letter.

Very truly yours,

Kirkwood Oil & Gas
