Dear Shareholder:

         You are cordially  invited to attend a special  meeting of shareholders
of Home-Stake Oil & Gas Company to be held at our offices at 15 East 5th Street,
Suite 2800, Tulsa, Oklahoma, on ____________, 2000, at 9:00 a.m., local time. At
the special meeting, you will be asked to consider and approve our merger with a
subsidiary   of  Cortez  Oil  &  Gas,   Inc.,  a   privately-owned   corporation
headquartered  in Plano,  Texas,  pursuant to an  agreement  and plan of merger,
dated as of October 3, 2000. You should read carefully the merger  agreement,  a
copy of which is  attached as Appendix A to the  accompanying  proxy  statement.
Upon completion of the merger,  each share of our common stock will be converted
automatically into the right to receive $11.00 in cash, without interest. We can
only complete the merger if the holders of a majority of the outstanding  shares
approve the merger agreement.

         Our board of directors  unanimously  approved the merger  agreement and
declared  the  merger  agreement  advisable  and in the  best  interests  of our
shareholders and unanimously recommends that our shareholders approve the merger
agreement.  Among the factors considered by our board of directors in evaluating
the merger was the opinion,  dated  September  27, 2000, of Stephens  Inc.,  our
financial advisor,  which provides that, as of that date, the cash consideration
to be  received by holders of our common  stock  pursuant to the merger was fair
from a  financial  point of view to our  shareholders.  The  written  opinion of
Stephens Inc. is attached as Appendix B to the accompanying  proxy statement and
should be read carefully and in its entirety.

         The proxy  statement  provides  you with a summary  of the  merger  and
additional  information about the parties  involved.  If the merger agreement is
approved by the requisite holders of our common stock, the closing of the merger
will occur as soon after the special  meeting as all of the other  conditions to
the closing of the merger are satisfied or waived.

         Please give all of this information your careful attention.  Whether or
not you plan to attend  the  special  meeting,  you are  requested  to  promptly
complete,  sign and date the  enclosed  proxy card and return it in the envelope
provided.  This will not  prevent  you from  voting your shares in person if you
subsequently  choose to attend the special  meeting.  If you have any  questions
regarding the proposed  transaction,  please call Mr. Chris K. Corcoran at (918)
583-0178, extension 14.

                                      Sincerely,

The Parties to the Merger (page 10)

Home-Stake Oil & Gas Company
15 East 5th Street, Suite 2800
Tulsa, Oklahoma 74103
(918) 583-0178

     In this proxy statement,  we call this company "Home-Stake."  Home-Stake is
an  Oklahoma  corporation  formed  in 1917  which  is  actively  engaged  in the
acquisition,  exploration, development and production of oil and gas properties.
Our  common  stock is traded on the  NASDAQ  SmallCap  Market  under the  symbol
"HSOG."

Cortez Oil & Gas, Inc.
Parkway Center II
2805 North Dallas Parkway
Suite 100
Plano, Texas 75093
(972) 781-6595

     In this  proxy  statement,  we call  this  company  "Cortez."  Cortez  is a
privately-held  independent  oil  and gas  exploration  and  production  company
headquartered in Plano,  Texas.  Cortez was formed as a Delaware  corporation by
management  and  Natural  Gas  Partners  V,  L.P.  in  March  2000 to  focus  on
acquisitions and exploitation drilling.


Cortez Acquisition Company
Parkway Center II
2805 North Dallas Parkway
Suite 100
Plano, Texas 75093
(972) 781-6595

     Cortez  Acquisition  Company is an Oklahoma  corporation and a wholly-owned
subsidiary of Cortez.  Cortez  Acquisition  Company was formed to facilitate the
consummation  of the  merger  and has  conducted  no  activities  other  than in
connection with the merger and the merger agreement.

The Merger (page 11)

     Cortez  Acquisition  Company will be merged with and into Home-Stake,  with
Home-Stake being the surviving corporation, pursuant to a merger agreement dated
as of October 3, 2000, among Cortez, Cortez Acquisition Company and us.

     At the effective time of the merger,  each outstanding  share of our common
stock will be converted  automatically into the right to receive $11.00 in cash,
without interest.

     After  the  completion  of the  merger,  Home-Stake  will be the  surviving
corporation and will be a wholly-owned  subsidiary of Cortez. The holders of our
common stock will have no continuing  equity  interest in, and will not share in
future earnings,  dividends or growth, if any, of the surviving corporation.  In
addition,  after the merger has been completed,  our common stock will no longer
be listed on the NASDAQ  SmallCap  Market or registered  with the Securities and
Exchange Commission.

Recommendation of Our Board of Directors and
Reasons for the Merger (page 13)

       After an  evaluation  of a variety  of  business,  financial  and  market
factors and consultation with our legal and financial advisors,  at a meeting on
September 27, 2000, our board of directors  determined that the merger agreement
was fair to, and in the best interests of, Home-Stake and our shareholders.  The
board  also  unanimously  approved  the  merger,  the merger  agreement  and the
transactions  contemplated by that agreement and unanimously  voted to recommend
that  our   shareholders   approve  the  merger   agreement.

                                       1
<PAGE>



       In reaching its recommendation, our board considered, among other things,
the following factors:

     o    our financial condition,  assets, results of operations,  business and
          prospects and the risks inherent in achieving those prospects;

     o    the fairness opinion of Stephens Inc.;

     o    terms and conditions of the merger agreement;
          and

     o    the trading history of our common stock,  which has been characterized
          by low daily trading volumes and the resulting illiquidity, typical of
          companies of similar size.

Opinion of Financial Advisor (page 16)

     On September 27, 2000,  Stephens  Inc.  rendered an opinion to our board of
directors that, as of the date of that opinion,  the $11.00 per share in cash to
be  received by holders of our common  stock was fair from a financial  point of
view to our shareholders.

     The full text of the written opinion of Stephens Inc.,  dated September 27,
2000, which sets forth the assumptions made,  matters considered and limitations
on the review undertaken in connection with the opinion, is attached as Appendix
B to, and is incorporated by reference in, this proxy statement.  The opinion of
Stephens Inc. does not constitute a  recommendation  as to how any holder of our
common stock should vote with respect to the merger.  You should  carefully read
the opinion in its entirety.

Financing Arrangements (page 20)

     In  connection  with entering into the merger  agreement,  Cortez  obtained
commitment  letters from Fleet  National  Bank and First Union  National Bank to
provide debt financing and a subscription agreement from Natural Gas Partners V,
L.P. to provide equity financing for the merger, on the terms and conditions set
forth in the commitment letters and the subscription  agreement.  As of the date
of this proxy statement,  the financing commitments are in full force and effect
and have not been terminated.

     Assuming the financings  described above are consummated,  Cortez will have
funding that is sufficient to pay the merger  consideration  to our shareholders
and all  associated  merger costs.  Cortez does not  anticipate  completing  any
financing until immediately prior to the closing of the merger, and no assurance
can be given that any financing  will be completed.  Cortez  currently  does not
have  any  alternative  financing  commitments  in  the  event  that  any of the
financing commitments described above is not obtained.

Interests of Officers and Directors in the Merger
That Differ From Your Interests (page 21)

     You should be aware that two of our  executive  officers are members of our
board of directors,  and these officers and our other  employees have agreements
that will provide  them with  interests  in the merger that are  different  from
yours.  Generally,  the merger will result in severance and bonus payments being
made to these  officers,  directors  and  employees.  The Cortez and  Home-Stake
boards were aware of these interests and considered them in approving the merger
agreement.

The Special Meeting (page 8)

     At the special meeting, our shareholders will be asked to consider and vote
upon a proposal to approve and adopt the merger agreement.

Record Date and Voting Power (page 8)

     Our board of  directors  has fixed the close of  business  on , 2000 as the
record date for determining  shareholders entitled to notice of, and to vote at,
the special meeting.

     On the record date, we had 4,353,827
outstanding shares of common stock held by
approximately 300 shareholders of record. We have
no other class of securities  outstanding.  Shareholders of record on the record
date will be entitled  to one vote per share of common  stock on any matter that
may properly come before the special meeting and any adjournment or postponement
of that meeting.

Vote Required (page 8)

     Approval and adoption of the merger agreement requires the affirmative vote
of a majority of outstanding shares of our common stock.

                                       2

<PAGE>



Voting Agreements (page 23)

     Our  directors  and  some  of  their  spouses,  who  own  an  aggregate  of
approximately 21.1% of our outstanding shares of common stock, have entered into
agreements to vote for the merger.

Proxies, Voting and Revocation (page 8)

     Shares of common  stock  represented  at the  special  meeting by  properly
executed proxies  received prior to or at the special meeting,  and not revoked,
will be voted at the special  meeting,  and at any adjournments or postponements
of that meeting,  in accordance with the instructions on the proxies. If a proxy
is duly executed and submitted without instructions,  the shares of common stock
represented  by that  proxy  will be voted  "For"  the  approval  of the  merger
agreement. Proxies are being solicited on behalf of our board of directors.

     A proxy may be revoked by the person  who  executed  it at, or before,  the
special meeting by:

o    delivering to our secretary a written  notice of revocation of a previously
     delivered proxy bearing a later date than the proxy;

o    duly executing,  dating and delivering to our secretary a subsequent proxy;
     or

o    attending the special meeting and voting in person.

Attendance  at the  special  meeting  will  not,  in and of  itself,  constitute
revocation of a proxy.

     The  merger  will  become  effective  as of the  date  and  time  that  the
certificate  of merger is accepted  for filing by the  Secretary of State of the
State of Oklahoma in accordance with the Oklahoma General Corporation Act, which
is expected to occur as soon as practicable after  shareholder  approval and the
satisfaction or waiver of all other conditions to closing of the merger.

Exchange of Stock Certificates (page 24)

     At the  effective  time of the merger,  Cortez will  deposit with UMB Bank,
N.A., our stock transfer agent who is also acting as the exchange agent, cash in
an amount  sufficient  to pay the holders of shares of common stock  outstanding
immediately  prior to the effective time of the merger,  other than shareholders
exercising their appraisal rights,  the cash merger  consideration to which they
are entitled under the merger agreement.

     The merger  agreement  provides  that within three  business days after the
effective time of the merger,  the exchange agent will send to each  shareholder
of  record,  as of  immediately  prior  to  the  effective  time,  a  letter  of
transmittal and detailed  instructions  specifying the procedures to be followed
in surrendering stock  certificates.  You should not send any stock certificates
to the  exchange  agent or to  anyone  else  until  you  receive  the  letter of
transmittal.  Upon the surrender of a stock certificate, the exchange agent will
issue to the surrendering holder the consideration described above.

Conditions to the Merger (page 30)

     For the merger to occur,  the holders of a majority of the shares of common
stock outstanding must approve the merger agreement and the parties must satisfy
or waive all other conditions specified in the merger agreement, including:

o    that  Cortez,   Cortez  Acquisition  Company  and  Home-Stake  receive  all
     consents,  approvals,  permits and  authorizations  required to be obtained
     from any governmental entity or third party;

o    that no temporary restraining order, preliminary or permanent injunction or
     other order issued by any court of competent  jurisdiction,  or other legal
     restraint or prohibition  preventing  the  completion of the merger,  be in
     effect;

o    that  no  event  or  events  have  occurred  that,  individually  or in the
     aggregate,   would  have  a  material   adverse  effect  on  our  business,
     properties,  condition,  financial or otherwise,  or results of operations;
     and

o    the completion and satisfaction by Fleet National Bank of its due diligence
     investigation,  customary  for debt  financing  transactions  of this type,
     insofar  as it  relates  to  title  to  our  oil  and  gas  properties  and
     environmental matters involving those properties.

Solicitation of Proposals from Other Parties (page 27)

     In accordance  with the merger  agreement,  we have agreed that,  until the
termination of the merger agreement or the effective time of the merger, we will
not  authorize  or permit any of our  directors,  officers,  employees,  agents,
attorneys,  independent  accountants,  independent  financial  advisors or other
affiliates or representatives to initiate,  solicit, facilitate or encourage any
inquiries or proposals  that  constitute or are  reasonably  likely to lead to a
merger,  consolidation  or similar  transaction  involving  us or a proposal  to
acquire a substantial portion of our stock or assets.

     We must notify Cortez  promptly in writing with respect to any  unsolicited
inquiry or proposal which we have received that is reasonably  likely to lead to
a merger proposal.

     We have no right to terminate  the merger  agreement if we receive an offer
from a third party to acquire us that is superior to Cortez's offer, but in such
a case our board retains the right to rescind or modify its recommendation  that
our shareholders approve the merger agreement.

Termination of the Merger Agreement (page 31)

     The merger  agreement  may be terminated at any time prior to the effective
time of the merger by, among other things,  the mutual written  agreement of the
parties or, after the  occurrence  of certain  events or actions,  by one of the
parties  acting  independently.  For  example,  either  party may  independently
terminate the merger agreement if:

o    the merger has not been completed by February 28, 2001;

o    our shareholders holding in excess of a majority of our common stock do not
     vote to approve the merger; or

o    any governmental  authority takes any action prohibiting the merger,  which
     action becomes final and non-appealable.

In addition, Cortez may terminate the merger agreement if our board withdraws or
modifies its recommendation or the special  shareholders  meeting to approve the
merger is not held prior to February 26, 2001.

Termination Fee; Expenses (page 31)

     If the merger  agreement  is  terminated  because  our board  withdraws  or
modifies its recommendation, because the special shareholders meeting to approve
the merger is not held prior to February 26, 2001,  or because our  shareholders
fail to approve  the  merger,  then we must pay Cortez a  termination  fee of $2
million.

Appraisal Rights (page 34)

     If you do not vote in favor of the proposal to approve and adopt the merger
agreement and you comply strictly with the applicable provisions of the Oklahoma
General  Corporation Act, and the requisite  number of our shareholders  approve
the merger  agreement,  you have the right to  dissent  and be paid cash for the
"fair value" of your shares. This payment may be more than, the same as, or less
than the merger  consideration you would receive in the merger. To perfect these
appraisal  rights,  you must  follow  the  required  procedures  precisely.  The
applicable  provisions of the Oklahoma  General  Corporation Act are attached to
this  document as Appendix C. It is a condition to the  completion of the merger
that  holders of not more than five  percent of the  outstanding  voting  shares
entitled  to vote at the  special  meeting  elect to  exercise  their  appraisal
rights.

Federal Income Tax Consequences (page 36)

     If the merger is completed,  the exchange of our common stock by any of our
shareholders  in  return  for  the  merger   consideration  will  be  a  taxable
transaction under the Internal Revenue Code of 1986. Because of the complexities
of the tax laws, we advise you to consult your own tax advisors  concerning  the
applicable federal,  state, local, foreign and other tax consequences  resulting
from the merger.

     available and we will no longer file periodic  reports with the  Securities
     and Exchange Commission under the Securities Exchange Act of 1934.

<PAGE>



Q:   What will happen to present members of Home-Stake's management?

A:   At or prior to the merger,  each of the  members of our board of  directors
     and our officers will resign. Upon consummation of the merger, the officers
     of Cortez  Acquisition  Company will become the  officers of the  surviving
     corporation.

Q:   Did the Home-Stake board retain financial advisors?

A:   To  assist  it in making  its  recommendation  regarding  the  merger,  the
     Home-Stake  board  retained  Stephens  Inc.  as its  financial  advisor  in
     connection  with its evaluation of the merger.  Stephens Inc.  delivered to
     the Home-Stake  board an opinion to the effect that, as of the date of that
     opinion,  the per share merger  consideration to be received by the holders
     of our  common  stock  was fair,  from a  financial  point of view,  to the
     holders of our common  stock.  We have attached as Appendix B to this proxy
     statement  the full text of the opinion of Stephens  Inc. This opinion sets
     forth the  assumptions  made,  matters  considered  and  limitations on the
     review taken in connection with the opinion.

Q:   What rights do I have if I oppose the merger?

A:   Under  Oklahoma  law, you are entitled to appraisal  rights.  If you do not
     vote in  favor of the  merger  and you  properly  elect  to  exercise  your
     appraisal  rights as  described  under  "You Have  Appraisal  Rights in the
     Merger" and in  Appendix C, you may receive in the merger the "fair  value"
     of your  common  stock as  determined  by a court.  The fair value could be
     equal to, less than or more than $11.00 per share.

Q:   When do you expect the merger to be completed?

A:   We are working to complete the merger before the end of the year.

Q:   Who can help answer my questions?

the Securities and Exchange Commission. All statements, other than statements of
historical  facts,  included in this proxy  statement  that address  activities,
events or developments  that we expect,  believe or anticipate will or may occur

                               THE SPECIAL MEETING

Date, Time and Place of the Special Meeting

       The  special  meeting  will be held at our offices at 15 East 5th Street,
Suite 2800, Tulsa, Oklahoma, on ________, 2000, at 9:00 a.m., local time.

Purpose of the Special Meeting

       At the special  meeting,  you will be asked to  consider  and vote upon a
proposal  to approve  and adopt the merger  agreement  relating to the merger of
Cortez Acquisition Company with and into Home-Stake,  with Home- Stake being the
surviving  corporation.  As a result of the  merger,  Home-Stake  will  become a
wholly-owned subsidiary of Cortez.

Record Date and Voting Power

       Our board of  directors  has fixed the close of business  on  __________,
2000,  as the record  date for the  determination  of  shareholders  entitled to
notice of, and to vote at, the special  meeting.  As of the record  date,  there
were  outstanding  shares of common stock held by  approximately  300 holders of
record. Our common stock is our only outstanding class of stock. Shareholders of
record on the record  date will be  entitled to one vote per share of our common
stock on any matter  that  properly  comes  before the  special  meeting and any
adjournment or postponement of that meeting.

Quorum and Vote Required

       Our bylaws require the presence,  in person or by duly executed proxy, of
the holders of shares of common  stock  representing  at least a majority of our
outstanding shares of common stock at the special meeting in order to constitute
a quorum. Approval and adoption of the merger agreement requires the affirmative
vote of a majority of the outstanding  shares of our common stock.  For purposes
only of determining  the presence or absence of a quorum for the  transaction of
business,  we intend to count abstentions and broker non-votes as present at the
special meeting.  Abstentions and broker non-votes are not, however,  counted as
favorable  votes and,  therefore,  have the same  effect as a vote  against  the
proposal. Broker non-votes are proxies from brokers or other nominees indicating
that they have not  received  instructions  from the  beneficial  owner or other
person  entitled  to vote the  shares  which are the  subject  of the proxy on a
particular  matter with  respect to which the broker or other  nominee  does not
have discretionary voting power.

Proxies, Voting and Revocation

       Shares of our common stock represented at the special meeting by properly
executed proxies received prior to, or at, the special meeting, and not revoked,
will be voted at the special meeting,  and at any adjournment or postponement of
that meeting,  in accordance with the instructions on those proxies.  If a proxy
is duly executed and submitted  without  instructions,  the shares of our common
stock  represented  by that proxy will be voted "For" the approval of the merger
agreement. Proxies are being solicited on behalf of our board.

       A proxy may be  revoked  at any time  before  it is voted at the  special
meeting. A proxy may be revoked by the person who executed it at, or before, the
special meeting by:

o      delivering  to  our  secretary  a  written  notice  of  revocation  of  a
       previously-delivered proxy bearing a later date than the proxy;

o      duly  executing,  dating and  delivering  to our  secretary a  subsequent
       proxy; or


                                       8

<PAGE>



o      attending  the special  meeting and voting in person.  Attendance  at the
       special  meeting will not, in and of itself,  constitute  revocation of a
       previously delivered proxy.

Any written notice  revoking a proxy should be delivered to Home-Stake Oil & Gas
Company, 15 East 5th Street, Suite 2800, Tulsa, Oklahoma,  74103, Attention: Mr.
Chris K. Corcoran, Secretary.

Solicitation of Proxies and Expenses

       We will  bear  the  entire  cost of  solicitation  of  proxies  from  our
shareholders.  Copies of  solicitation  materials will be furnished to brokerage
houses,  fiduciaries and custodians  holding in their names shares of our common
stock  beneficially  owned by  others to  forward  to those  beneficial  owners.
Original  solicitation  of proxies by mail may be  supplemented  by telephone or
personal solicitation by our directors,  officers or other regular employees. No
additional compensation will be paid to our directors, officers or other regular
employees  for these  services,  but these  individuals  may be  reimbursed  for
out-of-pocket  expenses  incurred  in  connection  with the  solicitation.  Upon
request, we will reimburse brokers, dealers, banks or similar entities acting as
nominees for their  reasonable  expenses  incurred in  forwarding  copies of the
proxy materials to the beneficial owners of the shares of common stock they hold
of  record.  In  addition,  we  have  engaged  _____________  to  assist  in the
solicitation  of  proxies.  We  anticipate  that we  will  incur  total  fees of
approximately $_____________, plus reimbursement of out-of- pocket expenses, for
this service.

2001 Annual Meeting of Shareholders of Home-Stake

       We will hold our 2001 annual meeting of  shareholders  only if the merger
is not  consummated.  In  the  event  of the  annual  meeting,  any  shareholder
proposals  intended  to be  presented  at the  meeting  must be  received at our
principal  executive  offices on or before  December  11,  2000,  in order to be
included in our proxy materials relating to that meeting.

                            THE PARTIES TO THE MERGER

Home-Stake Oil & Gas Company

       We are actively engaged in the acquisition,  exploration, development and
production of oil and gas properties.  Our principal  geographic operating areas
lie within the states of Oklahoma, Montana, New Mexico and Texas.

       We were  incorporated  in the State of  Oklahoma in 1917.  Our  principal
business activity from the date of incorporation through the early 1950s was the
acquisition  and  leasing of oil and gas  mineral  interests.  Accordingly,  our
revenues were  primarily from royalty  interests in oil and gas production  from
the mineral  interests in properties  leased to others.  In the 1950s,  we began
participating  as a working  interest partner in the acquisition and drilling of
oil and gas properties,  primarily drilled and operated by industry partners. We
also  originated and  participated in the drilling of a few of our own prospects
and discovered several significant oil fields in south central Kansas during the
1950s.  Beginning in 1985, we developed an exploration  staff to generate,  sell
and drill our own  prospects.  We now also serve as an  operator  for  producing
wells.

       In the mid-1970s, we revised our business strategy to pursue a program to
increase our revenues  generated from the ownership of working  interests in oil
and gas properties  relative to our revenues  generated  from royalty  interests
resulting  from the ownership and leasing of oil and gas mineral  interests.  We
increased  our relative  investment in drilling  ventures  developed and sold by
other industry  partners and in the oil and gas properties that we acquired.  In
1977,  we received  approximately  70% of our revenues  from royalty  interests,
whereas, in 1999, approximately 26% of our revenues were from royalty interests.

Cortez Oil & Gas, Inc.

       Cortez is a newly  formed  Delaware  corporation  that has not,  to date,
conducted any significant activities other than those incident to its formation,
its execution of the merger  agreement,  the related documents and the financing
commitments and its  participation  in the preparation of this proxy  statement.
Cortez  has no  material  assets  or  liabilities,  other  than its  rights  and
obligations under the merger agreement,  the related documents and the financing
commitments,  and has not generated any material revenues or expenses.  Cortez's
growth strategy involves a coordinated balance of acquisitions, exploitation and
exploration. It is anticipated that drilling and production operations of Cortez
will be located in Texas, Oklahoma, New Mexico and Montana.

Cortez Acquisition Company

       Cortez Acquisition Company is an Oklahoma  corporation recently formed by
Cortez to facilitate the  consummation  of the merger.  It has not conducted any
business or activity except in connection with activities related to the merger.

                                   THE MERGER

General

       The  merger  agreement  provides  for the  merger of  Cortez  Acquisition
Company  with  and  into   Home-Stake,   with  Home-Stake  being  the  surviving
corporation.  The merger will be completed  when the  certificate  of merger has
been  accepted for filing by the  Secretary of State of the State of Oklahoma in
accordance with the Oklahoma General Corporation Act, which is expected to occur
as soon as  practicable  after the  shareholder  approval  of the merger and the
satisfaction or waiver of all other conditions to closing the merger.

       As of the effective  time of the merger,  holders of shares of our common
stock will have no further  ownership  interest  in the  surviving  corporation.
Instead, each holder of common stock issued and outstanding immediately prior to
the effective  time of the merger will be entitled to receive $11.00 in cash per
share,  without  interest.  Upon  completion of the merger,  all of Home-Stake's
outstanding  stock  options will be canceled  and, in full  settlement  of these
options,  Cortez will cause  Home-Stake  to pay each option  holder an amount of
cash equal to the number of shares of common stock  underlying each stock option
held by that holder  multiplied by the difference  between $11.00 and the option
exercise price applicable to that option.

Background of the Merger

       During the course of 1999, our management continued its previous strategy
of acquiring,  operating and developing oil and gas properties. In the meantime,
various members of our board, in both formal and informal discussions, expressed
concern that, in our present  structure and at our present size, we would not be
able  to  successfully   grow  at  a  rate  acceptable  to  our  board  and  our
shareholders.  Some of our  shareholders  also  expressed  similar  concerns  to
various  members of our board.  At regular  meetings of the board on January 22,
May 24, August 5 and November 4, 1999,  our board  continued to discuss our past
and  current  operations,  our stock price  activity  in the market,  our future
strategic  direction and methods by which  shareholder  value might be enhanced,
including our possible sale.

       At the November 4th board meeting,  our chairman,  Mr. Simpson,  told the
board that our stock price was,  and would likely  remain,  at levels well below
the true value of the company,  due largely to the lack of liquidity  created by
our  extremely  low  trading  volume.  He  recommended  that we explore  various
strategic  alternatives to maximize  shareholder  value and improve  shareholder
liquidity.  Our  board  agreed  that  it  was  in  the  best  interests  of  our
shareholders  for  our  management  to  consider   strategic   alternatives  and
authorized  management  to retain an  investment  banking  firm as an advisor to
assist us in soliciting,  evaluating and exploring  strategic  alternatives.  On
November 11, 1999, we issued a press release announcing our intention to explore
various strategic alternatives.

       During  November and  December  1999,  Mr.  Simpson met  informally  with
representatives of several investment banking firms. At a special meeting of the
board on January 14, 2000, Mr.  Simpson  described the results of these meetings
and reviewed written proposals from six different firms. He recommended that the
board narrow the list to two or three firms, that those firms be asked to submit
additional  information  regarding their proposals and that a final selection of
an  investment  banking  firm be  made  at the  February  board  meeting.  After
discussion,  the board  narrowed  the list to two firms and  compiled  a list of
questions for Mr. Simpson to provide these firms.

       At the meeting of our board on February 18, 2000,  the board reviewed the
proposals of the two remaining  investment  banking firms and selected  Stephens
Inc. as our financial  advisor.  Over the next two weeks we negotiated the terms
of an engagement  agreement  with Stephens Inc. On February 29, 2000, we entered
into the agreement with Stephens Inc. and issued a press release announcing that
we had hired Stephens Inc. to assist us in exploring strategic alternatives.


                                       11

<PAGE>



       At a  special  meeting  of our  board on March 29,  2000,  Stephens  Inc.
presented a written  report  analyzing  our strategic  alternatives.  The report
considered  various  options  for  us,  including   remaining   independent  and
continuing  our strategy of  acquiring,  operating  and  developing  oil and gas
properties,  merging with a larger  entity or completing an outright sale of our
stock or assets  for cash.  Despite  an  improving  environment  for oil and gas
companies resulting from higher prevailing energy prices, our board continued to
express  concern that our growth and market  value would  likely  continue to be
hindered by our small size and illiquid trading market. Accordingly,  the board,
after  evaluating the various  options  presented,  authorized  Stephens Inc. to
"test the waters" for qualified buyers  principally  interested in a transaction
involving a sale of the company for cash.

       During the next several weeks, our management and Stephens Inc.  prepared
a data room and offering materials to help describe us, including our properties
and  exploitation  potential,  to  potential  purchasers.  Stephens  Inc.  began
contacting  potential purchasers in order to ascertain their interest in us, and
a form of  confidentiality  agreement,  including a  standstill  provision,  was
prepared.

       Stephens Inc. contacted 119 potential  purchasers.  It mailed preliminary
brochures  to  93  of  these   candidates.   Twenty-three   companies   returned
confidentiality  agreements,  including Cortez,  most of whom were then provided
with detailed  reserve  information.  Nine  companies,  including  Cortez,  sent
representatives  to our data room.  On June 23, 2000, a total of six  proposals,
including a proposal by Cortez,  to  purchase  us were  received,  four of which
involved a purchase of our stock for cash.

       On June 28,  2000,  a special  meeting  of our board was held in Tulsa to
consider  the  proposals  which had been  received.  All  directors,  except Mr.
Morris, who participated by telephone  conference,  were present in person. Also
present were our legal counsel and  representatives  of Stephens  Inc.  Stephens
Inc.  presented  to our  board  an  analysis  of the  proposals  which  had been
received.  Our board discussed the relative advantages and disadvantages of each
proposal,  the  strengths  of each  company's  indication  of  interest  and the
likelihood  that each company would be able to finance its  proposal.  The board
then  determined  that at least three of the  proposals,  including the proposal
submitted by Cortez, were sufficiently attractive to warrant further discussions
with the potential purchasers.

       During the next few  weeks,  meetings  were held with the three  selected
potential  purchasers,  including  Cortez,  in an effort to get them to increase
their respective purchase prices. Throughout this period, representatives of the
three candidates  continued their due diligence  investigation of us in order to
supplement  information  previously learned from their evaluation of us. On July
26,  2000,  revised bids to purchase us were  submitted  by the three  potential
purchasers.

       Our board  convened a special  meeting on August 3, 2000, to evaluate the
latest proposals, including a revised bid submitted by Cortez on August 2, 2000.
All directors  were present in person,  along with  representatives  of Stephens
Inc. and our legal counsel.  After  reviewing the latest  proposals,  Cortez was
contacted by  telephone  by  representatives  of Stephens  Inc.  while the board
meeting was in progress and  requested to increase  its purchase  price.  Cortez
responded by increasing its purchase price. Our board determined that the Cortez
proposal was the best offer  received.  After  further  discussion of whether we
should  remain  independent  and  continue  our  business  strategy,  the  board
determined  that it was in the best interests of our  shareholders to pursue the
Cortez offer.  Accordingly,  management was instructed to begin  negotiating the
terms of a definitive  merger  agreement with Cortez.  Negotiation of definitive
documentation  proceeded  in earnest  and  Cortez  continued  its due  diligence
investigation of us.

       In connection with our negotiations  with Cortez,  on August 17, 2000, we
signed an  exclusivity  letter  agreement  with Cortez which  prohibited us from
soliciting or responding to other offers or inquiries  until September 15, 2000.
We determined  that it was in our best  interests to sign the letter  because of
its short  duration and because Cortez was expending  significant  resources and
time in connection  with the  preparation of documents,  due diligence and other
activities in connection with the possible  transaction  and,  accordingly,  was
unlikely to proceed without it.

       Thereafter,  representatives  of Cortez and us continued to negotiate the
terms of the merger  agreement.  On September 14, 2000, a special meeting of our
board was held by  telephone  conference  call for the purpose of  updating  the
board on the status of the negotiations  with Cortez.  During the  negotiations,
the  exclusivity  period with Cortez was  extended to September  30,  2000,  and
Cortez  agreed  to an  increase  in the  purchase  price to  $11.00  per  share.
Negotiations  on the remaining  terms of the merger  agreement  continued  until
September  27,  2000.  During this  process,  our board was further  informed of
developments through various informal meetings and telephone conversations.

       On September 27, 2000,  our board,  together with its financial and legal
advisors,  convened a special meeting to consider the proposed merger  agreement
and the  transactions  contemplated  by that  agreement,  including the purchase
price. Mr. Simpson, together with our legal and financial advisors, reviewed the
background of the proposed merger,  the potential  benefits of the merger to our
shareholders, financial and valuation analyses of the transaction, and the terms
of the merger agreement and related  documents.  Stephens Inc.  delivered to our
board its oral  opinion,  subsequently  confirmed  in  writing,  that,  based on
matters  presented  to  our  board  and  as  set  forth  in  its  opinion,   the
consideration  to be received by the holders of our common stock pursuant to the
merger  agreement was fair to such holders,  taken as a whole,  from a financial
point of view.  After  considering the presentation of Mr. Simpson and our legal
advisor and the  presentation  and opinion of Stephens Inc.,  along with various
other factors discussed below, our board unanimously:

o      approved the merger agreement and the  transactions  contemplated by that
       agreement;

o      authorized our officers to execute the merger agreement on our behalf;

o      approved  a  recommendation  that our  shareholders  vote in favor of the
       approval of the merger agreement;

o      approved the voting  agreements to be entered into with our directors and
       some of their spouses;

o      approved the separation  agreements to be entered into with Mr.  Simpson,
       our chairman,  and Mr.  Corcoran,  our executive vice president and chief
       financial officer; and

o      approved  the  amendment to our rights  agreement  which would render the
       rights inapplicable to the merger and the other transactions contemplated
       by the merger agreement.

       During the next several days the merger  agreement and related  documents
were finalized.  On September 29, 2000, the  exclusivity  period with Cortez was
extended to October 6, 2000.

       On October 3, 2000,  officers of Cortez and us executed and delivered the
merger  agreement and our  directors  and some of their  spouses  agreed to vote
their  shares  of our  common  stock  in  favor  of the  merger  and the  merger
agreement. On October 3, 2000, we issued a press release announcing the proposed
merger with Cortez.

Recommendation of Our Board of Directors and Reasons for the Merger

       As described  above in the section  entitled  "Background of the Merger,"
our  board  unanimously  approved  the  merger,  the  merger  agreement  and the
transactions  contemplated  by that agreement at a meeting held on September 27,
2000. Our board believes that the terms of the merger,  the merger agreement and
the other  transactions  contemplated  by that agreement are fair to, and in the
best  interests of,  Home-Stake  and its  shareholders.  Accordingly,  our board
recommends approval of the merger agreement by our shareholders. In reaching its
conclusion to approve the merger and the merger  agreement,  our board consulted
with our management and our legal counsel, and was advised by Stephens Inc., our
financial advisor in this  transaction.  The board considered our short-term and
long-term  interests and those of our  shareholders.  In  particular,  our board

                                       13

<PAGE>



considered the following factors, all of which it deemed favorable,  in reaching
its decision to recommend the merger and the merger agreement:

o      The  consideration  to be  received  by our  shareholders  in the  merger
       represents a premium of:

       o      85% over the  closing  price of $5.94 on each of  February  28 and
              February 22, 2000,  which was one day and one week,  respectively,
              prior to the  announcement  that  Stephens  Inc. had been hired to
              serve as our financial advisor; and

       o      112% over the  closing  price of $5.19 on each of  November 10 and
              November  4, 1999,  which was one day and one week,  respectively,
              prior  to  the  announcement   that  we  would  explore  strategic
              alternatives;

o      the financial  condition,  assets,  results of  operations,  business and
       prospects of Home-Stake;

o      the trading history of our common stock,  which has been characterized by
       low daily  trading  volumes  and the  resulting  illiquidity,  typical of
       companies of similar size;

o      the  opinion of  Stephens  Inc.  that the  consideration  to be issued by
       Cortez in the merger was fair,  from a  financial  point of view,  to the
       holders of our common stock,  and the various  analyses  presented to our
       board of directors by Stephens Inc. See "Opinion of Financial Advisor" at
       page 16;

o      the ability of the board to change its recommendation if it determines in
       good faith, based on matters it deems appropriate,  after consulting with
       legal  counsel,  that the failure to change its  recommendation  would be
       reasonably  likely to result in a breach of its  fiduciary  duties  under
       applicable law; and

o      the terms and  conditions of the merger  agreement,  including the amount
       and form of  consideration,  the nature of the parties'  representations,
       warranties, covenants and agreements, and the fact that the conditions to
       Cortez's  obligation to consummate the merger are reasonably  limited and
       thus the risk that the merger  would not be  consummated  was  reasonably
       small.

       Our board also  considered  the fact that  Cortez has  obtained  debt and
equity commitments to provide the financing  necessary to consummate the merger.
The Board considered the controlling ownership of Cortez, consisting of National
Gas Partners V, L.P., affiliates of which have provided equity financing in many
similar  transactions.  The board also concluded that the conditions to the debt
financing  commitment  letters were likely to be satisfied and that Cortez would
be  able  to  obtain  the  financing   necessary  for  the  merger  and  related
transactions.

       Our board of directors  consulted with Stephens Inc. during the course of
its  engagement.  The board of directors  believed that Stephens Inc.'s analysis
was reasonable.

       Our board of directors also considered  other  strategic  alternatives to
the merger that might be available to us, including:

o      remaining  independent  and  continuing  to expand our business  into new
       geographical areas;

o      pursuing  other  business   combinations,   including  mergers  involving
       companies with significantly  greater market capitalization than our own;
       and

o      rejecting the Cortez offer and soliciting additional bids from interested
       third parties.

                                       14

<PAGE>




The board considered the strategic  options  available to us and determined that
none of these options was reasonably  likely to present superior  opportunities,
or was reasonably likely to create greater value for our shareholders,  than the
prospects presented by the merger.  After considering the potential benefits and
risks to us and our shareholders associated with each of these alternatives, our
board determined that the merger represented the alternative that is in the best
interests of our shareholders.

o      Our board also considered the following  potentially  negative factors of
       the  merger in its  deliberations  concerning  the  merger and the merger
       agreement.

o      Our board  acknowledged that the merger would preclude the holders of our
       common stock from having the  opportunity  to  participate  in the future
       growth of our assets.

o      In the event that Cortez is unable to raise the  necessary  financing for
       the merger,  our sole remedy is to terminate the merger agreement and sue
       Cortez for any resulting damages.

o      Our  board  of  directors  acknowledged  that  the  merger  is a  taxable
       transaction  and,  as a  result,  holders  of our  common  stock  will be
       required to pay taxes on any built-in  gain as a result of their  receipt
       of the cash consideration in the transaction.

o      Our board considered the covenant in the merger agreement restricting our
       ability to solicit or entertain other potential acquisition proposals.

o      Our board  considered  that we will have to pay a $2 million  termination
       fee if the merger agreement is terminated under  circumstances  specified
       in the merger agreement.

o      Our board  considered  the risks and costs to us if the  merger  does not
       close,  which risks and costs would result from, among other things,  the
       extensive  efforts  that would be  required  to attempt to  complete  the
       transaction  and the  significant  distractions  which our employees will
       experience during the pendency of the transaction.

       Our board also  considered the potential  benefits to certain  directors,
officers and employees  discussed in the section entitled "Interests of Officers
and Directors in the Merger,"  including the severance and bonus  payments to be
paid to Messrs.  Robert C. Simpson and Chris K. Corcoran under their  respective
separation  agreements,  the severance  payments to be made to each of our other
eligible  employees under our Amended and Restated  Change in Control  Severance
Pay Plan and the  acceleration  of the  vesting  of all  outstanding  options to
acquire our common stock.

       In the opinion of our board,  the above  factors  represent  the material
potential adverse  consequences  which could occur as a result of the merger. In
considering the merger,  our board considered the impact of these factors on our
shareholders.

       In view of the wide variety of factors considered by our board, our board
did not find it practicable  to, and did not,  quantify or otherwise  attempt to
assign relative weights to the specific factors considered. Our board viewed its
position and  recommendation  as being based on the totality of the  information
presented to, and  considered  by, it. After taking into  consideration  all the
factors set forth above, the board determined that the potential benefits of the
merger outweighed the potential detriments associated with the merger.

       In the event the merger is not completed for any reason, we will continue
to  explore  various  strategic  alternatives  to  maximize  shareholder  value,
including other business combination opportunities.

Opinion of Financial Advisor

       At the special  meeting of our board on September  27, 2000,  to consider
approving and adopting the merger  agreement,  Stephens Inc.  delivered its oral
opinion  (subsequently  confirmed by a written opinion dated September 27, 2000)
that, as of such date, the merger  consideration  was fair to our  shareholders,
taken as a whole, from a financial point of view.

       A copy of the opinion of Stephens  Inc.,  which sets forth the  principal
assumptions made, matters considered and limitations on the review undertaken by
Stephens Inc. in rendering its opinion,  is attached as Appendix B to this proxy
statement and is  incorporated  by reference.  This summary of the Stephens Inc.
opinion  addresses the material  items on which Stephens Inc. based its opinion.
You are strongly encouraged to carefully read the opinion in its entirety.

       The Stephens Inc.  opinion was provided to our board for its  information
and is directed  only to the  fairness,  from a financial  point of view, to our
shareholders  of the  consideration  to be  received  by our  shareholders.  The
Stephens Inc.  opinion does not  constitute a  recommendation  to any Home-Stake
shareholder  as to how that  holder  should  vote on the  approval of the merger
agreement or as to whether the merger would be beneficial to any shareholder.

       The summary set forth below  describes  material  aspects of the analyses
underlying Stephens Inc.'s opinion and the presentation made by Stephens Inc. to
our board. The preparation of a fairness opinion is a complex analytical process
involving various determinations as to the most appropriate and relevant methods
of financial  analysis and the  application  of those methods to the  particular
circumstances.  Therefore,  the Stephens Inc. opinion is not readily susceptible
to partial analysis or summary description. In arriving at its opinion, Stephens
Inc.  did  not  attribute  any  particular  weight  to any  analysis  or  factor
considered by it, but rather made  qualitative  judgments as to the significance
and relevance of the analyses and factors considered. Accordingly, Stephens Inc.
believes  that its analyses  must be  considered  as a whole and that  selecting
portions of its analyses,  without considering all of its analyses, could create
an  incomplete or inaccurate  view of the process  underlying  the Stephens Inc.
opinion.

       In  arriving  at its  opinion,  Stephens  Inc.  met  with  our  executive
management  to discuss our  business,  operations  and  prospects.  In addition,
Stephens Inc. reviewed:

o      a draft of the merger  agreement  dated  September 25, 2000,  and related
       documents;

o      our annual  report on Form 10-KSB for the year ended  December  31, 1999,
       and our quarterly reports on Form 10-QSB and related unaudited  financial
       information for the interim periods,  including the six months ended June
       30, 2000;

o      our  proved  oil  and  gas  reserves  and  the  standardized  measure  of
       discounted  future net cash flows relating to proved oil and gas reserves
       as of December 31, 1999, estimated by our management;

o      our capitalization and financial condition;

o      historical market prices and trading volumes for our common stock;

o      the financial terms of business  combinations  of comparable  exploration
       and production companies; and

o      other  information,  financial  studies,  analyses and investigations and
       financial,  economic and market criteria as Stephens Inc. deemed relevant
       in arriving at its opinion.

                                       16

       In preparing its opinion,  Stephens Inc. did not independently verify any
of the foregoing information, and relied upon the information being complete and
accurate in all  material  respects.  Stephens  Inc.  did not conduct a physical
inspection or make an  independent  evaluation or appraisal of our assets,  nor,
except for the estimates of oil and gas reserves referred to above, was Stephens
Inc.  furnished with any evaluation or appraisal.  The Stephens Inc. opinion was
rendered on the basis of  conditions in the  securities  markets and oil and gas
markets   prevailing  on  September  27,  2000.  We  did  not  provide  specific
instructions  to, or place any limitation on,  Stephens Inc. with respect to the
procedures  to be  followed  or factors to be  considered  by  Stephens  Inc. in
performing its analyses or providing its opinion.

       The  following  is a summary  of the  material  aspects  of the  analyses
performed by Stephens Inc. in preparing the Stephens Inc. opinion.

       Recent Stock Price Performance Analysis. Stephens Inc. compared the stock
price performance of our common stock for the periods commencing on November 10,
1999 and February 28, 2000,  which were one day before the  announcement  of our
intention to explore strategic  alternatives to increase  shareholder value, and
one day before the announcement  that we had hired Stephens Inc.,  respectively,
and  ending on  September  25,  2000  (using an assumed  purchase  price for our
shareholders  of $11.00 per share on such  date),  with the  performance  of the
companies  included in the Standard & Poor's Small-Cap Energy Index and an index
of 13 companies compiled by Stephens Inc. that it believed to be appropriate for
comparison. These companies were:

o      Louis Dreyfus Natural Gas Corp.;

o      Vintage Petroleum Inc.;

o      Pure Resources, Inc.;

o      Belco Oil & Gas Corp.;

o      Comstock Resources, Inc.;

o      Magnum Hunter Resources, Inc.;

o      Key Production, Inc.;

o      Bellwether Exploration Company;

o      Brigham Exploration Company;

o      PetroCorp, Inc.;

o      Maynard Oil Company;

o      Goodrich Petroleum Corporation; and

o      Texoil, Inc.

Eleven of these 13 companies have a significantly  larger market  capitalization
than we have.

       As a result of the  foregoing  analysis,  Stephens  Inc.  noted  that the
increase of 112% from the $5.19 stock price on November 10, 1999, to the assumed
offer price of $11.00 per share on  September  25, 2000,  compared  favorably to
increases in the Standard & Poor's  Small-Cap  Energy Index and Stephens  Inc.'s
comparable company index of 40.5% and 95.1%, respectively. Stephens Inc. further

                                       17

<PAGE>



noted that the  increase of 85.2% from the $5.94  stock  price on  February  28,
2000, to the $11.00 per share offer price, also compared  favorably to increases
of 40.7% and 77.2%,  respectively,  to the  Standard & Poor's  Small-Cap  Energy
Index and Stephens Inc.'s comparable company index.

       Premiums Paid  Analysis.  Stephens  Inc.  reviewed the premiums paid over
market value in 76 merger or acquisition  transactions  ranging from $20 million
to $1.0 billion in size and completed from May 1992 through June 2000, where the
acquired company made a prior  announcement  indicating its intention to explore
strategic  alternatives.  As a result of the foregoing  analysis,  Stephens Inc.
noted  that at the offer  price of $11.00  per share,  the  premium  paid to our
shareholders of 112% over its stock price both one day and one week prior to the
announcement  of its intention to explore  strategic  alternatives  exceeded the
mean premium of 46.3% and median  premium of 35.0% over the target's stock price
one day before the announcement and the mean premium of 52.7% and median premium
of 43.8% over the target's stock price one week before the announcement.

       Comparable  Company  Analysis.  Stephens Inc.  compared certain financial
information  and commonly used valuation  measurements  for us to  corresponding
information  and  measurements  for the 13 companies  listed above under "Recent
Stock Price Performance  Analysis." These financial information and measurements
included, among other things:

o      ratios of stock price to latest 12 months cash flow per share;

o      ratios of stock price to estimated  fiscal year 2000 cash flow per share;
       and

o      ratios of market  value of common  equity  plus  total debt less cash and
       cash equivalents, commonly referred to as "Total Market Capitalization,"
       to  latest  12  month  earnings  before  interest,  taxes,  depreciation,
       depletion and amortization, commonly referred to as "EBITDA."

       Stephens  Inc.  noted  that the ratio of stock  price to latest 12 months
cash flow per share for the 13  comparable  companies  ranged from 2.0x to 6.7x,
with a mean of 4.9x and a median of 5.0x.  Based on these ratios,  Stephens Inc.
derived an implied  trading  value range for our common stock of $3.64 to $12.01
per share, with a mean of $8.70 and a median of $8.96 per share.

       Stephens  Inc.  noted that the ratio of stock price to  estimated  fiscal
year 2000 cash flow per share for the 13 comparable  companies  ranged from 1.6x
to  7.2x,  with a mean of 4.0x  and a median  of  3.9x.  Based on these  ratios,
Stephens Inc.  derived an implied trading range for our common stock of $3.18 to
$14.33 per share, with a mean of $7.93 and a median of $7.65 per share.

       Stephens   Inc.   further   noted  that  the   ratios  of  Total   Market
Capitalization  to EBITDA for the 13  comparable  companies  ranged from 3.3x to
7.6x  with a mean and  median  of 5.8x.  Based on these  ratios,  Stephens  Inc.
derived an  implied  trading  range for our common  stock of $6.53 to $15.61 per
share, with a mean of $11.84 and a median of $11.72 per share.

       Comparable  Transactions  Analysis.  Stephens Inc. conducted a comparable
transactions  analysis by  examining  the terms of publicly  disclosed  domestic
acquisitions  of businesses and assets related to the exploration and production
industry for the period January 1, 2000,  through September 20, 2000, as tracked
by John S. Herold, Inc. This analysis yielded an implied reserve value,  defined
as total transaction value less the value of non-oil and gas assets, of:

o      $4.59 per barrel of oil equivalent, known as "boe," for all transactions;

o      $3.90 per boe for Mid-Continent transactions;

                                       18

<PAGE>




o      $4.03 per boe for  transactions  with a total  transaction  value ranging
       from $25 million to $100 million; and

o      $2.72 per boe for  Mid-Continent  transactions  with a total  transaction
       value ranging from $25 million to $100 million.

       Because the  majority of the  comparable  transactions  were asset sales,
Stephens Inc. estimated how the reserves may have been valued by Cortez as if it
were an asset  transaction by adding assumed  liabilities in the transaction and
the tax  burden  of a cash  for  stock  transaction  versus  a cash  for  assets
transaction.  Stephens Inc.  calculated the tax burden based on the tax basis of
the properties,  the taxable gain assumed by Cortez, and an approximation of the
income  taxes to be paid by Cortez  over the life of the  reserves  based on our
reserve  report and  discounted  back to the date of the fairness  opinion.  For
discount  rates,  Stephens  Inc.  chose our cost of equity  as  calculated  by a
capital  asset  pricing  model and the  weighted  average  cost of  capital of a
purchaser  with a capital  structure of 50% debt and 50% equity.  Stephens  Inc.
used  three  cases in  calculating  the value of the  reserves.  The first  case
assumed no tax burden,  the second case assumed the tax burden was discounted by
our cost of equity,  and the third case assumed the tax burden discounted by the
weighted  average  cost  of  capital  of a  purchaser  whose  capital  structure
consisted of 50% debt and 50% equity.  The estimated  implied reserve values for
the three respective cases were $58 million, $66 million and $68 million.

       Stephens  Inc.  also  estimated  our proved  reserves  at the time of the
opinion by adjusting our December 31, 1999 reserve report for production through
June 30,  2000,  and  drilling  results  for 2000  year to date.  Stephens  Inc.
estimated that we had 12.3 million boe as of September 25, 2000.

       Based on the  Cortez  offer  price of $11.00  per  share,  Stephens  Inc.
estimated  that Cortez was paying $4.71 per boe, $5.37 per boe and $5.52 per boe
for our proved reserves for the three respective cases described above.

       Stephens Inc.'s Engagement Agreement. Stephens Inc. was retained to:

o      assist  the  board  of  directors   with  the   evaluation  of  strategic
       alternatives;

o      assist the board in preparing  confidential  data,  contacting  potential
       purchasers and  facilitating  due diligence  investigations  by potential
       purchasers; and

o      render  its  opinion  on the basis of its  experience  with  mergers  and
       acquisitions in the energy business.

Stephens  Inc.  is a  nationally  recognized  investment  banking  firm  and  is
regularly  engaged  in the  valuation  of  businesses  and their  securities  in
connection  with mergers and  acquisitions,  negotiated  underwritings,  private
placements and valuations for corporate and other purposes. The Home-Stake board
of  directors  selected  Stephens  Inc.  as  financial  advisor  because  of its
expertise, reputation and familiarity with us.

       Under the terms of the engagement agreement between us and Stephens Inc.,
we  paid  Stephens  Inc.  a fee of  $50,000  upon  execution  of the  engagement
agreement  and  $50,000  upon the  decision by our board to begin the process of
marketing the company and also  reimbursed  Stephens Inc. for its  out-of-pocket
expenses. In addition, we will pay Stephens Inc. a percentage of the total value
of the merger consideration  payable in the merger if the merger is consummated,
which amount  shall not exceed  $826,000.  We have agreed to reimburse  Stephens
Inc. for  additional  out-of-pocket  expenses  incurred in  connection  with its
rendering of the fairness opinion,  which amount shall not exceed $1,500, and to
indemnify  Stephens Inc. and its  controlling  persons  against  liabilities and
expenses relating to or arising out of the consummation of the merger, including
liabilities   under   federal   securities   laws.   To  the  extent   that  the
indemnification  includes  liabilities arising under federal securities laws, it
may not be enforceable  as it may be determined to be against public policy.  No
portion of  Stephens  Inc.'s  fee was  contingent  upon  whether  Stephens  Inc.
rendered a favorable  opinion with respect to the proposed merger.  The terms of
Stephens  Inc.'s   engagement   agreement  with  us,  which  are  customary  for

                                       19

transactions  of this nature,  were negotiated at arm's length between our board
and  Stephens  Inc.,  and our board was aware of these  terms at the time of its
approval of the merger agreement.

Financing Arrangements

       Cortez  estimates  that it will require  approximately  $57.3  million in
order to finance the merger. These funds will be used to:

o      pay the merger  consideration,  including  payments for the  surrender of
       outstanding stock options; and

o      pay the fees and expenses incurred in connection with the merger.

Cortez expects to obtain these funds from the following sources:

o      the  performance  by Fleet  National Bank under its commitment to provide
       $22 million in debt financing for the merger transaction;

o      the  performance  by First Union  National  Bank under its  commitment to
       provide $20 million in debt financing for the merger transaction; and

o      the injection of $20.6 million in cash by Natural Gas Partners V, L.P., a
       shareholder  of Cortez,  upon a call for payment by Cortez  pursuant to a
       subscription  agreement  between  Natural Gas Partners and Cortez for the
       purchase of Cortez common stock.

       Cortez has obtained financing commitment letters from Fleet National Bank
and First Union  National  Bank and a  subscription  agreement  from Natural Gas
Partners  V, L.P.,  with  respect to the terms of the  financing  or  investment
described  above.  The  obligations of Fleet National Bank to provide  financing
will terminate in the event comprehensive loan documentation has not been signed
on or before  December 26, 2000.  The term loan is expected to be secured by the
assets  of  Cortez  and  its  subsidiaries   and  to  contain   representations,
warranties,  covenants, events of default and other terms that are customary for
a transaction of this type.

       The obligations of Fleet National Bank to provide the financing described
above are also  subject to the  satisfaction  by Cortez of  financial  tests and
other conditions, which include:

o      the absence of any material  adverse  change in the business,  condition,
       operations,  performance  or properties  of Cortez and its  subsidiaries,
       including Home-Stake;

o      the successful completion of the merger;

o      the receipt of any necessary  consents of third  parties or  governmental
       authorities;

o      the absence of any breach of any representation,  warranty or covenant in
       any loan document or other document relating to the merger;

o      the  injection  of cash into Cortez by Natural Gas  Partners as described
       above;

o      the  performance  by First Union  National  Bank under its  commitment to
       provide $20 million of debt financing;


                                       20

<PAGE>



o      the  preparation  and  execution  of  comprehensive   loan  documentation
       acceptable to Fleet National Bank and First Union National Bank;

o      the absence of any material misstatements or omissions from any financial
       information provided to Fleet National Bank; and

o      the  completion  and  satisfaction  by  Fleet  National  Bank  of its due
       diligence  investigation,  customary for debt financing  transactions  of
       this type, including but not limited to title to and condition, including
       environmental matters, of the properties of Cortez and us.

       In the merger  agreement,  Cortez  represents  and  warrants  to us that,
assuming  the  financings  described  above are  consummated,  Cortez  will have
funding  sufficient to pay the merger  consideration to our shareholders and all
associated merger costs.  Cortez further represents and warrants that, as of the
date of the merger agreement, it is not aware of any facts or circumstances that
create a  reasonable  basis for  Cortez to  believe  that it will not be able to
obtain  financing  in  accordance  with  the  terms  of its  existing  financing
commitments.  The merger  agreement  also requires  Cortez to notify us upon the
occurrence of any event which causes  Cortez to reasonably  believe that it will
not be able to obtain the financing described above.

       Cortez does not  anticipate  completing any financing  until  immediately
prior to the  closing  of the  merger,  and no  assurance  can be given that any
financing  will be completed.  Cortez  currently  does not have any  alternative
financing   commitments  in  the  event  that  any  of  its  existing  financing
commitments is not obtained.  If Cortez notifies us that it reasonably  believes
that it will not be able to obtain the financing  described  above, it will have
10  business  days to secure  alternative  financing  on terms  that  contain no
greater conditions than those contained in the original  financing  commitments.
The failure by Cortez to obtain  sufficient  financing  to  complete  the merger
would be considered a material breach of the merger agreement. If no alternative
financing is obtained within this 10 business day period, we will have the right
to terminate the merger  agreement  and seek damages for any losses  incurred in
connection with the failed merger transaction.

Interests of Officers and Directors in the Merger

       Robert C. Simpson,  our Chairman,  President and Chief Executive Officer,
and Chris K. Corcoran, our Executive Vice President, Chief Financial Officer and
Secretary,  each has an employment  agreement  with us which provides for a cash
severance  payment in the event his employment is terminated  following a change
in control  transaction.  Under their existing agreements,  Messrs.  Simpson and
Corcoran are each  entitled to a cash  severance  payment  equal to 36 times the
highest  monthly  salary paid to them  during the  12-month  period  immediately
preceding  the merger,  plus an amount  equal to the sum of the bonuses  paid to
each of them  over the past  three  years.  In  addition,  Messrs.  Simpson  and
Corcoran have an arrangement with us, which was previously approved by our board
of directors,  that in the event of a sale of  Home-Stake,  Mr. Simpson would be
paid an amount equal to 2.2% of the  "transaction  value" and Mr. Corcoran would
be paid a bonus of $200,000.

       In  connection  with the merger,  Messrs.  Simpson and Corcoran have each
entered into separation  agreements with us. The separation  agreements  provide
for the  cancellation  of the  employment  agreements  described  above and that
Messrs.  Simpson's and  Corcoran's  employment  with us will  terminate when the
merger is completed.  The separation  agreement for Mr. Simpson provides that he
will  receive a  one-time  cash  payment of  $1,867,149,  which  represents  the
severance  payment and the transaction  bonus described  above. In addition,  he
will receive a cash payment of $888,405 to cover taxes imposed on him by Section
4999 of the Internal  Revenue  Code or any similar  federal or state excise tax.
The separation agreement for Mr. Simpson also gives him the option of purchasing
a company  automobile  at the lesser of its book value as shown on our books and
records and its "blue book" fair market value.

                                       21

<PAGE>




       The separation agreement for Mr. Corcoran provides that he will receive a
one-time cash payment of $735,700,  which  represents the severance  payment and
the  transaction  bonus  described  above.  In addition,  he will receive a cash
payment  of  $326,805  to cover  taxes  imposed  on him by  Section  4999 of the
Internal Revenue Code or any similar federal or state excise tax.

       In 1999, the board of directors amended and restated the Home-Stake Oil &
Gas Company Change in Control Severance Pay Plan. The severance plan is designed
to provide severance  payments in the event that all or substantially all of our
assets or stock are  acquired by another  party.  An  "eligible  employee" is an
employee,  other than Robert C. Simpson or Chris K.  Corcoran,  who is receiving
salary for  personal  services  rendered  to us or who would be  receiving  such
remuneration  except for a leave of absence.  Under the severance plan, eligible
employees who have been employed by us for less than five years will be entitled
to three  months'  salary as severance  pay.  Eligible  employees  who have been
employed by us for five years or more will be entitled to one month's salary for
each year of  service  and a  pro-rata  portion  of one  month's  salary for any
fractional year of service as severance pay.  Department  managers identified in
the severance plan will receive,  in addition to the severance  payment based on
the years of service,  one year's compensation as part of the severance payment.
The minimum  payment  under the severance  plan is three months'  salary and the
maximum  payment is the lesser of (1) three years' salary or (2) $1.00 less than
the  amount  which  would  result  in the  imposition  of  excise  tax under the
so-called "excess parachute payment" provisions of the Internal Revenue Code. We
estimate that our employees  will be entitled to receive an aggregate  amount of
approximately $920,000 in severance payments under the severance plan.

       As of the closing of the merger,  all of our  outstanding  stock  options
will become fully vested and  exercisable.  In full settlement of these options,
Cortez will cause  Home-Stake  to make a cash payment to each option  holder who
returns an executed option surrender  agreement equal to the difference  between
the merger consideration that would be payable with respect to each share of our
common stock underlying that option and the applicable option exercise price. As
a result,  the options set forth in the following table held by our officers and
directors  will become fully vested and our officers and directors  will receive
approximately   (i.e.,   before  withholding)  the  indicated  cash  payment  in
settlement of his or her options.

       In addition,  under the terms of the merger agreement,  our directors and
officers  will be entitled to  indemnification  in some  circumstances,  as more
fully described in the section  entitled "The Merger  Agreement--  Covenants and
Agreements--Indemnification and Insurance of Home-Stake Officers and Directors."

performs  legal  services as our counsel.  Joseph J. McCain,  Jr., a director of
Home-Stake, is president and a shareholder and director of Conner & Winters.

Voting Agreements with Directors and Senior Management

       Cortez has entered into stock voting agreements with Messrs.  Simpson and
Corcoran and with all of the members of our board of directors and some of their
spouses.  In these  agreements,  our  officers and  directors  and some of their
spouses,  acting solely in their capacity as  shareholders of Home-Stake and not
in their  capacity as  directors  or officers of  Home-Stake,  agreed to vote in
favor of the  merger  and the  other  transactions  contemplated  by the  merger
agreement and not to encourage or solicit any competing offers.  These officers,
directors and spouses agreed not to transfer their shares before the merger.  In
the aggregate,  these officers,  directors and spouses own approximately 919,860
shares of our common stock, which accounts for approximately 21.1 percent of our
outstanding common stock.

Some Effects of the Merger

       If the merger is  completed,  holders of shares of our common  stock will
not have an opportunity  to continue  their equity  interest in us as an ongoing
corporation and, therefore, will not have the opportunity to share in our future
earnings,  dividends or growth,  if any. In  addition,  upon  completion  of the
merger,  our common stock will no longer be listed on the NASDAQ SmallCap Market
and will cease to be registered with the Securities and Exchange Commission.

Method of Accounting

       The merger will be accounted for under the purchase method of accounting.

                              THE MERGER AGREEMENT

       The terms of and  conditions  to the merger are  contained  in the merger
agreement, a copy of which is attached to this proxy statement as Appendix A and
incorporated in this document by reference.  Set forth below is a description of
the material terms and conditions of the merger.  This  description is qualified
in its entirety by, and made subject to, the more complete information set forth
in the merger agreement.

Effective Time of the Merger

       The merger will become effective when the Secretary of State of the State
of Oklahoma has accepted for filing the certificate of merger in accordance with
the Oklahoma General  Corporation Act. At that time, Cortez Acquisition  Company
will be merged  with and into  Home-Stake  and will cease to exist as a separate
entity and Home-Stake will become a wholly-owned subsidiary of Cortez. We expect
the merger to become  effective  as soon as  practicable  after  approval of the
merger  by our  shareholders  and  the  satisfaction  or  waiver  of  all  other
conditions to closing the merger.

Conversion of Shares Pursuant to the Merger

       At the effective time of the merger, each issued and outstanding share of
our common  stock will be  converted  into the right to receive  $11.00 in cash,
without interest.

Exchange of Stock Certificates

       Cortez has  designated  UMB Bank,  N.A., to act as exchange  agent in the
merger.  The merger agreement provides that within three business days after the
effective  time  of the  merger,  the  exchange  agent  will  mail a  letter  of
transmittal  to each  record  holder  of an  outstanding  stock  certificate  or
certificates,  which immediately prior to the effective time represented  shares
of our common  stock and were  converted  into the right to  receive  the merger
consideration.  The letter of  transmittal  will specify that  delivery  will be
effected  and risk of loss and title to stock  certificates  will pass only upon
proper delivery of the stock certificate to the exchange agent. In addition, the
exchange  agent  will also mail to each  record  holder  instructions  on how to
properly surrender the stock certificates for payment.  You should not surrender
your  stock   certificates  until  you  receive  a  letter  of  transmittal  and
instructions.

       Upon the  surrender  to the  exchange  agent of your  stock  certificate,
together  with a duly  executed  letter of  transmittal  and any other  required
documents,  and subject to any required  withholding of taxes,  you will be paid
the  merger  consideration  for  each  share  of  our  common  stock  previously
represented by your stock  certificate,  and the stock  certificate will then be
canceled.

       No  interest  will  be paid or  accrued  on the  cash  payable  upon  the
surrender of your stock  certificate.  Until  surrendered in accordance with the
provisions  stated above, each certificate will, after the effective time of the
merger, represent only the right to receive the merger consideration.

       After the  effective  time of the merger,  there will be no  transfers of
certificates that previously represented shares of our common stock on our stock
books.  If, after the effective time,  stock  certificates  are presented to the
surviving  corporation or the exchange agent for payment,  they will be canceled
and exchanged for the merger consideration, without interest. However, no holder
of a stock  certificate  will have any  greater  rights  against  the  surviving
corporation  than  may  be  accorded  to  general  creditors  of  the  surviving
corporation under applicable law.

       If you have lost a certificate, or if your certificate has been stolen or
destroyed,  in order to receive the merger consideration,  you will have to sign
an affidavit  stating that your  certificate was lost,  stolen or destroyed.  In

                                       24

<PAGE>



addition,  if Cortez requires,  you may have to post a bond indemnifying  Cortez
against  any claims  against it with  respect to the lost,  stolen or  destroyed
certificate.

       One year after the  closing of the merger,  upon  Cortez's  request,  the
exchange  agent will deliver to Cortez any cash held by the exchange  agent that
has not been paid to our shareholders pursuant to the merger agreement. From and
after that time, if you have not yet  exchanged  your shares of common stock for
the merger consideration, you must surrender your certificates to Cortez, rather
than the exchange agent, to receive the merger consideration.

Conduct of the Business Before the Merger

       We have agreed that, prior to the merger, we will generally:

o      conduct our business as usual;

o      preserve our present business organization;

o      operate and maintain our oil and gas  interests  in  accordance  with the
       law, applicable agreements and prudent practices;

o      keep available the services of our officers and employees;

o      pay all claims and expenses when they become due and payable; and

o      comply  with  all  applicable  laws and  regulations  and  provisions  of
       material agreements.

       In addition,  the merger  agreement  specifically  prohibits us,  without
Cortez's consent, from taking a number of corporate acts prior to the completion
of the merger, including the following actions:

o      amending organizational documents;

o      changing our capital stock;

o      paying any dividends;

o      issuing or encumbering  any shares or options except upon the exercise of
       currently existing options;

o      acquiring any of our capital stock;

o      merging or transferring all or substantially all of our assets;

o      liquidating, winding up or dissolving;


                                       25

o      acquiring  another  business  entity or an interest  in another  business
       entity;

o      disposing  of  or   encumbering   oil  and  gas  interests   meeting  the
       specifications set forth in the merger agreement;

o      acquiring  oil and gas interests or any other assets that have a value in
       excess of $25,000;

o      entering  into hedging or  derivative  contracts  unless  exempted in the
       merger agreement;

o      disposing of or encumbering securities of a third party;

o      making any loans or investments;

o      entering  into any  agreements  that would cause us to spend in excess of
       $5,000 or any agreements  that are not terminable by us upon notice of 30
       days or less and without penalty or other obligation;

o      agreeing to limit or restrict our ability to compete or otherwise conduct
       our business;

o      incurring any debt;

o      incurring any cost or expense for leasehold or geophysical items;

o      incurring any  obligations or liabilities  outside the ordinary course of
       business;

o      making a capital expenditure or series of related capital expenditures in
       excess of $5,000 unless exempted in the merger agreement;

o      becoming  liable  or  responsible  in any  way  for  the  liabilities  or
       obligations of a third party;

o      relinquishing voluntarily any right as operator of any of our oil and gas
       interests;

o      entering  into or becoming  liable or obligated  under or pursuant to any
       benefit plans,  employee  plans or agreements for directors,  officers or
       employees or modifying the plans or agreements;

o      paying or becoming  obligated  to pay any  benefits to our  employees  or
       consultants unless pursuant to an existing agreement;

o      entering into or amending any material agreements;

o      entering into a new line of business;

o      taking any action that causes our  representations  and warranties in the
       merger agreement to become untrue;

o      engaging in any transaction  with any of our affiliates  other than those
       specifically exempted in the merger agreement;

o      encumbering any of our assets unless exempted in the merger agreement;

o      entering  into any  agreement  relating  to the voting,  registration  or
       transfer of our securities; or


                                       26

<PAGE>



o      agreeing to take any of the above actions.

Covenants and Agreements

       Special  Meeting.  We have  agreed to cause the  special  meeting  of our
shareholders  to be duly  called and held as  promptly  as  practicable  for the
purpose of voting on the approval and adoption of the merger agreement.

       No Solicitation. In the merger agreement, we have agreed that:

o      we will  immediately  cease  and  cause  to be  terminated  any  existing
       activities,  discussions or  negotiations  conducted prior to the date of
       the merger agreement with respect to any Acquisition Proposal, as defined
       below; and

o      we will  not,  and will not  authorize  or permit  any of our  directors,
       officers,   employees,   agents,   attorneys,   independent  accountants,
       independent financial advisors or other affiliates or representatives to,
       solicit or encourage the submission of an Acquisition Proposal.

However, the merger agreement does not prohibit:

o      us from entering into discussions or negotiations  with a third party and
       furnishing that third party information concerning Home-Stake in response
       to an unsolicited Acquisition Proposal solely for purposes of determining
       whether or not to rescind or modify our  recommendation  of the merger or
       the merger agreement;

o      our board from taking and disclosing to our  shareholders a position with
       respect to a tender  offer by a third party  pursuant to Rule 14e-2 under
       the Securities Exchange Act of 1934; and

o      our board from withdrawing or modifying its approval or recommendation of
       the merger and the merger agreement;

if our board  determines that this action or disclosure is required in order for
our  board  to act in a  manner  consistent  with its  fiduciary  duties  to our
shareholders.

       The term  "Acquisition  Proposal"  means any proposal or offer that could
reasonably  be  expected  to lead to a  tender  or  exchange  offer,  a  merger,
consolidation or other business combination involving Home-Stake or any proposal
to acquire in any manner a substantial  equity  interest in, or any  substantial
portion of the assets of, Home- Stake.

       Indemnification  and  Insurance of  Home-Stake  Officers  and  Directors.
Cortez has agreed that, for six years after the merger is completed, Cortez will
indemnify  and  hold  harmless  the  present  and  former  directors,  officers,
employees,  controlling  shareholders  and agents of Home-Stake  against various
liabilities to the fullest extent  permitted under Oklahoma law. Cortez has also
agreed to maintain our directors' and officers'  liability and insurance policy,
for a period of at least six years after the merger is completed,  provided that
Cortez will not be  required  to pay an annual  premium in excess of 200% of the
last annual premium paid by us prior to the merger agreement.

       Additional Mutual Covenants. The merger agreement contains certain mutual
covenants of the parties, including covenants relating to:

o      preparation of this document;

o      public announcements;

                                       27

Termination of the Merger Agreement

       The merger agreement may be terminated at any time prior to the effective
time, whether before or after approval by our shareholders:

o      by the mutual written consent of Cortez and us;

o      by  either  Cortez  or us,  if the  merger  has not been  consummated  by
       February 28, 2001;

o      by either Cortez or us, if any final and  non-appealable  order,  decree,
       ruling or other action  enjoining any party from  consummating the merger
       shall have been entered by any governmental authority;

o      by either  Cortez or us, if the  requisite  shareholder  approval  is not
       obtained by a vote of our shareholders at the special meeting;

o      by us, if Cortez or Cortez  Acquisition  Company is in material breach of
       any  representations  and  warranties  and the breach is not cured in all
       material respects within 10 days after notice of the breach;

o      by  Cortez,  if we are in  material  breach  of our  representations  and
       warranties or our covenants and agreements and the breach is not cured in
       all material respects within 10 days after notice of the breach;

o      by Cortez, if we are in material breach of our covenants  relating to the
       conduct of our  business  prior to  closing,  without  regard to any cure
       period;

o      by  Cortez,  if our board of  directors  shall have  failed to  recommend
       adoption  of the merger  agreement  at the time this proxy  statement  is
       first  mailed  to  shareholders  or its  recommendation  is  subsequently
       amended or withdrawn; or

o      by Cortez,  if, from and after June 30,  2000,  our  business  incurs any
       material adverse effect.

Termination Fee

       If the merger is terminated:

o      due to the  failure  of our board to  recommend  adoption  of the  merger
       agreement  or  the  subsequent  withdrawal  or  amendment  of  its  prior
       recommendation;

o      because  the  special  shareholders  meeting to approve the merger is not
       held prior to February 26, 2001; or

o      due to our  shareholders'  failure to approve the merger agreement by the
       requisite vote;

we will pay to Cortez a termination fee equal to $2 million.

Merger Expenses

       The merger agreement  provides that all expenses  incurred by the parties
to the merger agreement shall be borne solely and entirely by the party that has
incurred the expenses. We will pay all costs and expenses in connection with the
printing of this document,  as well as all  Securities  and Exchange  Commission
filing fees and fees to comply with  applicable  state  securities or "blue sky"
laws related to the transactions contemplated by the merger agreement. The costs

                                       31

<PAGE>



and expenses  associated with mailing this document to our  shareholders and the
soliciting of votes of our shareholders will be borne by us.

Amendments

       The merger  agreement may be amended only by written  agreement of Cortez
and us at any time  before  the  effective  time.  However,  after the  required
Home-Stake  shareholder  approval is obtained,  no amendment  may be made to the
merger agreement that by law would require further approval by our shareholders,
unless such further approval is obtained.

Home-Stake Rights Plan

       We have a rights agreement with UMB Bank, N.A., as rights agent. Pursuant
to the merger  agreement,  we have amended the rights  agreement so as to render
the rights inapplicable to the merger and the other transactions contemplated by
the merger agreement.

       Pursuant to the rights  agreement,  rights attach to each share of common
stock  outstanding  and entitle the  registered  holder to purchase  from us one
one-thousandth of a share of our junior participating preferred stock, par value
$1.00 per share,  at a purchase  price of $22, which is subject to adjustment as
described in the rights  agreement.  Each share of our common stock  outstanding
has attached to it one right.

       The rights will separate from common stock upon the earlier of:

o      the  first  date  of  public  announcement  that a  person  or  group  of
       affiliated  or  associated  persons,  also  referred  to as a  Home-Stake
       acquiring  person,   has  acquired  or  obtained  the  right  to  acquire
       beneficial  ownership  of 15% or more of the  outstanding  shares  of our
       common stock; and

o      10  business  days  or  such  later  date as may be  fixed  by our  board
       following the commencement of a tender offer or exchange offer that would
       result  in a  person  or  group  beneficially  owning  15% or more of our
       outstanding shares of common stock.

       The date of any such event is referred to as the Home-Stake  distribution
date. Until the Home-Stake distribution date:

o      the rights will be evidenced by our common stock certificates and will be
       transferred with and only with our common stock certificates;

o      our common stock  certificates will contain a notation  incorporating the
       rights agreement by reference; and

o      the transfer of any  certificates  representing  our  outstanding  common
       stock will also constitute the transfer of the rights associated with our
       common stock represented by such certificate.

       If we are acquired in a merger or other business combination  transaction
or 50% or more of our  consolidated  assets or  earning  power are sold  after a
person or group has become a Home-Stake acquiring person, each holder of a right
will then  have the  right to  receive,  upon the  exercise  of the right at the
current  exercise  price of the right,  that number of shares of common stock of
the acquiring  company which at the time of the  transaction  will have a market
value of two times the exercise price of the right. In the event that any person
or group of  affiliated  or associated  persons  becomes a Home-Stake  acquiring
person,  each  holder of a right,  other than rights  beneficially  owned by the
Home-Stake acquiring person which will then be void, will then have the right to
receive upon  exercise that number of shares of our common stock having a market
value of two times the exercise price of the right.

                                       32

<PAGE>




       At any time  after any  person or group  becomes a  Home-Stake  acquiring
person and prior to the  acquisition  by that  person or group of 50% or more of
our outstanding  common stock,  our board may exchange the rights other than the
rights owned by that person or group,  which will have become void,  in whole or
in part, generally at an exchange ratio of one share of our common stock, or one
one-thousandth of a share of our junior participating  preferred stock, for each
two shares of our common stock for which each right is then exercisable.

       The rights are not exercisable until the Home-Stake distribution date and
will expire at the close of business on January 3, 2010, unless earlier redeemed
by us as further described in the rights  agreement.  At no time will the holder
of the rights have any voting  power or any rights as a  shareholder  due to his
position as a holder of the rights.  Subject to certain  exceptions,  any of the
provisions  of the rights  agreement  may be  amended by our board  prior to the
Home-Stake distribution date.

       The  above  summary  of the  rights  agreement  may not  contain  all the
information  that is important to you. For a more  detailed  description  of the
rights,  you  should  read the  rights  agreement  which has been filed with the
Securities and Exchange Commission. See "Where You Can Find More Information."

Treatment of Stock Options

       The  merger  agreement  provides  that each stock  option  under our 1997
Incentive  Stock Plan which is  outstanding  immediately  prior to the effective
time of the  merger,  whether  or not then  exercisable,  and which has not been
exercised  or  canceled  prior  to that  time,  will  become  fully  vested  and
exercisable.  Upon receipt of an executed option  surrender  agreement,  in full
settlement of all remaining outstanding options,  Cortez will cause us to pay to
each holder of an option an amount  equal to the product of the number of shares
of common  stock  underlying  that stock  option and the excess,  if any, of the
merger  consideration over the exercise price per share of common stock provided
for in that stock option. At and following the effective time of the merger, all
outstanding  options to purchase our common stock will automatically be canceled
and each stock option will  represent only the right to receive the cash payment
described above.

                     YOU HAVE APPRAISAL RIGHTS IN THE MERGER

General

       Our  shareholders  are entitled to dissent and be paid cash for the "fair
value" of their shares of our common stock.  This payment may be more than,  the
same as, or less than the merger  consideration our shareholders will receive in
the merger.  These  appraisal  rights  arise under  Section 1091 of the Oklahoma
General  Corporation Act, or OGCA.  Section 1091 of the OGCA is reprinted in its
entirety as Appendix C to this proxy statement.

Exercising Procedures

       The following  discussion  addresses  the material  provisions of Section
1091 of the OGCA. If you wish to exercise statutory appraisal rights or preserve
your right to do so, you should review this  discussion and Appendix C carefully
to comply strictly with the procedures set forth below and in Appendix C, or you
may lose your appraisal rights.

       If you elect to demand the appraisal of your shares, you must:

o      deliver to us before the  taking of the vote on the merger  agreement,  a
       written demand for appraisal of your shares; and

o      not vote in favor of the merger agreement.

Your demand is in addition to and  separate  from your proxy or vote against the
merger agreement.  Voting against, abstaining from voting, or failing to vote on
the merger agreement will not constitute a demand for appraisal. If you elect to
demand appraisal  rights,  you will not be granted  appraisal rights if you have
voted in favor of, or consented in writing to, the merger  agreement,  including
by granting the proxy solicited by this proxy statement or by returning a signed
proxy without  specifying a vote against the merger  agreement or a direction to
abstain from the vote. Additionally, appraisal rights will not be granted if you
do not  continuously  hold your shares of our common  stock for which you demand
appraisal through the effective time of the merger.

       You must fully and correctly  sign your demand for appraisal as your name
appears on the  certificate  or  certificates  representing  your  shares of our
common  stock.  If your  shares  of our  common  stock  are owned of record in a
fiduciary capacity, such as by a trustee,  guardian or custodian,  the fiduciary
must  execute the demand.  If the shares of our common stock are owned of record
by more than one person,  as in a joint tenancy or tenancy in common,  all joint
owners must execute the demand. An authorized agent,  including an agent for two
or more joint owners, may execute your demand for appraisal.  However, the agent
must identify you as the record owner and  expressly  disclose the fact that, in
exercising the demand,  that person is acting as your agent.  If you hold shares
of our common  stock  through a broker  who in turn  holds the shares  through a
central securities depository nominee such as Cede & Co., a demand for appraisal
must  be made  on  behalf  of the  depository  nominee  and  must  identify  the
depository nominee as a holder of record.

       If you elect to exercise your appraisal rights,  you must mail or deliver
your written  demand to us at 15 East 5th Street,  Suite 2800,  Tulsa,  Oklahoma
74103, Attention: Mr. Chris K. Corcoran. Your written demand must specify:

o      your name and mailing address;

o      the number of shares of our common stock that you own; and

o      that you are demanding appraisal of your shares.


                                       34

Within 10 days after the  effective  time of the  merger,  we, as the  surviving
corporation,  must provide notice of the effective time to all  shareholders who
have  complied  with Section 1091 and who have not voted for or consented to the
merger agreement.

Fair Value Determination

       Within 120 days after the effective time of the merger,  either we or any
shareholder  who has  complied  with  Section  1091  may file a  petition  in an
Oklahoma  district court demanding a determination of the value of the shares of
our common stock held by dissenting shareholders. If a petition for an appraisal
is timely  filed,  after a hearing  on the  petition,  the  district  court will
determine which  shareholders are entitled to appraisal rights and will appraise
the shares of our common stock owned by those  shareholders.  The district court
will determine the fair value of those shares  exclusive of any element of value
arising from the  accomplishment  or expectation of the merger,  together with a
fair rate of interest to be paid, if any,  upon the amount  determined to be the
fair value.  In determining  fair value,  the district court is required to take
into account all relevant factors.

       If you seek  appraisal,  you  should  know that the "fair  value" of your
shares of our common stock determined under Section 1091 could be more than, the
same as, or less than the merger  consideration  you will receive in the merger,
and that the  fairness  opinion of  Stephens  Inc.  is not an opinion as to fair
value  under  Section  1091.  Moreover,  we  reserve  the right to assert in any
appraisal proceeding that, for purposes of Section 1091, the "fair value" of the
common stock is less than $11.00 per share.

Costs

       The cost of the  appraisal  proceeding  may be determined by the district
court and assessed  against the parties as the district court deems equitable in
the circumstances.  Upon application of a dissenting  shareholder,  the district
court may order that all or a portion of the expenses incurred by any dissenting
shareholder in connection with the appraisal  proceeding,  including  reasonable
attorneys'  fees and the fees and  expenses  of  experts,  be  charged  pro rata
against the value of all shares of our common stock entitled to appraisal.

Withdrawal; Loss of Appraisal Rights

       At any time within 60 days after the  effective  time of the merger,  you
will have the right to  withdraw  your  demand for  appraisal  and to accept the
terms offered in the merger. After this period, you may withdraw your demand for
appraisal only with our consent.  If no petition for appraisal is filed with the
district  court  within  120  days  after  the  effective  time  of the  merger,
shareholders'  appraisal  rights  will  cease,  and all holders of shares of our
common stock will be entitled to receive the merger consideration as provided in
the merger agreement.  Because we have no obligation to file any petition for an
appraisal, and have no present intention to do so, any dissenting shareholder is
advised to file a petition for appraisal on a timely basis. However, no petition
timely filed by a shareholder in the district court demanding  appraisal will be
dismissed  without the approval of the district court,  and that approval may be
conditioned on any terms that the court deems just.


       You should be aware that any  failure to proceed in  accordance  with the
provisions of Section 1091 will result in loss of appraisal rights. In addition,
if the merger is abandoned prior to its  consummation,  no appraisal rights will
be available.

                         FEDERAL INCOME TAX CONSEQUENCES

       Following is a discussion of the material federal income tax consequences
of the merger to our  shareholders.  The  discussion  is based upon the Internal
Revenue Code, Treasury regulations, IRS rulings, and judicial and administrative
decisions  in effect as of the date of this  proxy  statement.  This  discussion
assumes that your Home-Stake  common stock is generally held for investment.  In
addition,  this discussion does not address all of the tax consequences that may
be relevant to you in light of your  particular  circumstances  or to any of our
shareholders  subject to  special  rules,  such as  non-United  States  persons,
financial  institutions,  tax-exempt  organizations,  dealers in  securities  or
foreign currencies or insurance companies.

       Your receipt of cash for  Home-Stake  common stock pursuant to the merger
will be a taxable transaction for federal income tax purposes to you, and may be
a taxable  transaction  for state,  local and foreign tax purposes as well.  You
will recognize a gain or loss measured by the difference  between your tax basis
for the  Home-Stake  common stock owned by you at the time of the merger and the
amount of cash you receive for your Home-Stake  common stock.  Your gain or loss
will be a  capital  gain or loss if your  Home-Stake  common  stock is a capital
asset in your  hands.  If your  Home-Stake  common  stock  was held as a capital
asset, your gain or loss will be long-term capital gain or loss if you held your
stock for more than one year; otherwise, it will be short-term gain or loss.

       Under  federal  law,  the  exchange  agent must  withhold 31% of the cash
payments  to holders  of  Home-Stake  common  stock to whom  backup  withholding
applies, and the federal income tax liability of such persons will be reduced by
the amount withheld. To avoid backup withholding,  you must provide the exchange
agent with your taxpayer  identification number and complete a form in which you
certify  that  you have not been  notified  by the IRS that you are  subject  to
backup  withholding.   The  exchange  agent  will  include  the  form  with  the
transmittal  letter and  instructions  which specify the  procedures  for you to
follow in surrendering your common stock certificate(s).

       The tax  consequences  of the merger to you may vary  depending upon your
particular  circumstances.  Therefore,  you should  consult  your tax advisor to
determine the particular tax consequences of the merger to you,  including those
relating to state, local and/or foreign taxes.

                         REGULATORY AND OTHER APPROVALS

       There are no federal or state regulatory  requirements which remain to be
complied  with in order to consummate  the merger,  other than the filing of the
certificate of merger with the Secretary of State of the State of Oklahoma.  The
merger  did not  require  filings  with the  Federal  Trade  Commission  and the
Department of Justice under the Hart-Scott-Rodino  Antitrust Improvements Act of
1976, as amended.

           PRINCIPAL SHAREHOLDERS AND SECURITY OWNERSHIP OF MANAGEMENT

       The following  table sets forth our information as of September 30, 2000,
relating to the beneficial ownership of our common stock, by

o      any  person  known  to  us to  own  beneficially  more  than  5%  of  the
       outstanding shares of common stock,

o      each of our directors,

o      each of our executive officers, and

o      all of our current executive officers and directors as a group.

       Shares of common  stock  which were not  outstanding  but which  could be
acquired by a person upon  exercise of an option  within sixty days of September
30, 2000, are deemed  outstanding for the purpose of computing the percentage of
outstanding shares beneficially owned by that person. These shares, however, are
not deemed to be  outstanding  for the purpose of computing  the  percentage  of
outstanding shares beneficially owned by any other person.

       Except  as  otherwise  indicated,  each of the  persons  named  below  is
believed by us to be the direct owner and to possess sole voting and  investment
power  with  respect to the shares of common  stock  beneficially  owned by that
person.

cancellation  to the Exchange  Agent,  together with such letter of transmittal,
duly  executed,  the holder of such  Company  Certificate  shall be  entitled to
promptly receive in exchange therefor payment by check of an amount equal to the
product  of the  Merger  Consideration  multiplied  by the  number  of shares of
Company  Common  Stock  formerly   represented   by  the   surrendered   Company

Company   Certificate  so  surrendered   shall  forthwith  be  canceled.   Until
surrendered as  contemplated by this Section  2.5(b),  each Company  Certificate
shall be deemed from and after the Effective Time to represent only the right to

Certificate the Merger Consideration.

              (d) No  Transfer.  After the  Effective  Time,  there  shall be no

              (e) Termination of Exchange Fund. Any portion of the Exchange Fund
held by the Exchange Agent in accordance with the terms of this Section 2.5 that
remains unclaimed by the former  shareholders of the Company for a period of one
year  following  the Effective  Time shall be delivered to Parent,  upon demand.
Thereafter,  any former  shareholders  of the Company  who have not  theretofore
complied  with the  provisions of this Section 2.5 shall look only to Parent for
payment of their claim for Merger Consideration (all without interest).

              (f) Option Surrender Agreements.  Within 20 days after the date of
this Agreement,  the Company shall distribute an option surrender  agreement (an
"Option Surrender Agreement"),  in the form delivered to the Company immediately
prior to execution of this Agreement,  to each holder of a Company Option. After
the  Effective  Time,  Parent shall cause the Surviving  Corporation  to pay the
amount of cash due to each holder of a Company Option under Section 2.4(b)(iii),

Pay Plan, as such may be applicable) all severance,  bonus and other amounts set
forth in Section 3.17(g) of the Company Disclosure Schedule.

              (h) No Liability.  None of Parent, the Surviving Corporation,  the
Exchange  Agent,  or any other  Person  shall be liable to any former  holder of
shares of Company  Common  Stock or  Company  Options  for any  amount  properly
delivered to any public official pursuant to any applicable  abandoned property,
escheat,  or similar law. Any amounts  remaining  unclaimed by former holders of
shares of Company Common Stock or Company  Options after a period of three years
following the Effective Time (or such earlier date immediately prior to the time
at which such  amounts  would  otherwise  escheat to or become  property  of any
governmental  entity) shall,  to the extent  permitted by applicable law, become
the  property  of Parent  free and clear of any claims or  interest  of any such
holders or their  successors,  assigns,  or personal  representative  previously
entitled thereto.

binding  obligations of the Company,  enforceable  against it in accordance with
their terms.

         3.4 No  Violations.  The  execution  and  delivery of each  Transaction
Document does not, and the consummation of the transactions  contemplated hereby
and thereby and compliance by the Company with the provisions  hereof or thereof
will not,  conflict with, result in any violation of or default (with or without
notice or lapse of time or both)  under,  give  rise to a right of  termination,
cancellation  or  acceleration  of any  obligation  or to the loss of a material

risk and  expense,  reasonable  access to any of the assets,  books and records,

sole risk and  expense,  have the right to make an  environmental  and  physical
assessment of the assets of the Company and, in connection therewith, shall have
the right to enter and inspect such assets and all  buildings  and  improvements
thereon,  conduct  soil and water tests and borings and  generally  conduct such
tests,  examinations,  investigations  and  studies as Parent  deems  necessary,

Representatives not to) disclose any of such data, information or results to any
Person  unless  otherwise  required  by law or  regulation  and then only  after
written notice to the Company of the  determination  of the need for disclosure.
Parent   shall   indemnify,   defend  and  hold  the  Company  and  the  Company
Representatives  harmless  from and  against  any and all  claims to the  extent
arising  out of or as a  result  of the  activities  of  Parent  and the  Parent

environmental  and physical  assessment,  except to the extent of and limited by

degree to the value, ownership,  use, operation,  development or transferability

date hereof  relating to the Merger or the Proxy  Statement;  and (ii)  promptly
advise Parent of the substance of any oral  communications with the SEC relating

control  of the  Company  but  subject  to a valid and  binding  confidentiality
agreement  with a third party without first  obtaining the consent of such third
party, and the Company,  to the extent reasonably  requested by Parent, will use
its reasonable best efforts to obtain any such consent.

         5.3    No Solicitation.

                (a) From and after the date  hereof,  the Company  will not, and
will not authorize or permit any of the Company  Representatives to, directly or
indirectly, solicit or encourage (including by way of providing information) any
prospective acquiror or the invitation or submission of any inquiries, proposals
or offers or any other efforts or attempts that constitute, or may reasonably be
expected to lead to, any Acquisition  Proposal (as hereinafter defined) from any
Person or engage in any  discussions  or  negotiations  with respect  thereto or
otherwise  cooperate  with or assist or  participate  in, or facilitate any such
proposal;  provided,  however,  that notwithstanding any other provision of this
Agreement,  (i) the  Company's  Board of Directors  may take and disclose to the
shareholders of the Company a position contemplated by Rule 14e-2(a) promulgated
under the Exchange Act and (ii) to the extent that the Board of Directors of the
Company  determines  in good faith,  after  considering  the advice of its legal
counsel, that such action is required in order for the Board of Directors of the
Company to act in a manner consistent with its fiduciary duties under applicable
law and solely for purposes of  determining  whether or not to rescind or modify
the  recommendation  of the Board of  Directors of the Company  contemplated  by
Section  5.5,  the Company and the  Company  Representatives,  in response to an
unsolicited  Acquisition  Proposal,  may enter into  discussions or negotiations
with the Person presenting such Acquisition  Proposal and provide information to
such  Person;   provided  that  prior  to  entering  into  such  discussions  or
negotiations  or providing any such  information  the Company shall enter into a
customary  confidentiality  agreement with such Person  containing terms no more
favorable to such Person than contained in the  Confidentiality  Agreement.  The
Company  shall  immediately  cease  and  cause  to be  terminated  any  existing
solicitation,  initiation,  encouragement,  activity,  discussion or negotiation
with any parties  conducted  heretofore  by the Company or any of the  Company's
Representatives  with  respect to any  Acquisition  Proposal.  The Company  will
promptly  notify in writing  Parent of any  receipt by the Company or any of the
Company  Representatives  of a  request  from  a  third  party  for  information
concerning the Company and its business, properties and assets or the receipt of
any  Acquisition  Proposal,  including  the  identity  of the  person  or  group
requesting  such  information  or  making  such  Acquisition  Proposal,  and the
material terms and conditions of any Acquisition Proposal.

                (b) As used in this agreement,  "Acquisition Proposal" means any
proposal  or  offer,  other  than a  proposal  or offer by  Parent or any of its
Affiliates,  for, or that could be  reasonably  expected to lead to, a tender or
exchange offer, a merger,  consolidation or other business combination involving
the  Company or any  proposal  to acquire  in any  manner a  substantial  equity
interest in, or any substantial portion of the assets of, the Company.

                (c)  Nothing in this  Section  5.3 shall  permit the  Company to
terminate this Agreement except as specifically provided in Section 7.1.

         5.4 Third-Party Standstill Agreements.  During the period from the date
hereof  through the  Effective  Time,  the Company shall not  terminate,  amend,
modify or waive any provision of the Rights Agreement or of any  confidentiality
or standstill  agreement to which the Company is a party,  except for the Rights
Agreement Amendment.

         5.5 Shareholders  Meeting.  The Company shall take all action necessary
in accordance  with  applicable  law and its  certificate of  incorporation  and
bylaws to convene a meeting of its shareholders as promptly as practicable after
the date hereof for the purpose of voting on the  Company  Proposal.  Subject to
the  fiduciary  duties of the Board of Directors of the Company and Section 5.3,
the Company will (through its Board of Directors)  recommend to its shareholders
approval of the Company  Proposal and not rescind or modify such  recommendation
and shall use its reasonable best efforts to obtain approval and adoption of the
Company Proposal by its shareholders. If, however, the Board of Directors of the
Company rescinds or modifies such recommendation pursuant to the first clause of
the immediately  preceding sentence,  the Company Proposal shall be submitted to
the Company's shareholders.

         5.6    Proxy Statement.

                (a) The Company and Parent shall cooperate and the Company shall
promptly  prepare  the Proxy  Statement  to enable the Company to file the Proxy
Statement with the SEC, as preliminary  proxy  material,  as soon as practicable
after the date  hereof  and in any event not later  than 20 days  after the date
hereof.  The Company shall use all  reasonable  best  efforts,  and Parent shall
cooperate  with the Company  (including  furnishing all  information  concerning
Parent  as may be  reasonably  requested  by the  Company),  to have  the  Proxy
Statement cleared by the SEC as promptly as practicable after such filing and to
mail the Proxy  Statement  to the  Company's  shareholders  as soon as  possible
thereafter.  The Company shall use all reasonable best efforts, and Parent shall
cooperate  with  the  Company,  to  obtain  any  necessary  state  anti-takeover
approvals in connection with the Merger.

                (b) The Company will cause the Proxy  Statement,  at the time it
is first  mailed to  shareholders  of the  Company,  to comply as to form in all
material  respects with the  applicable  provisions of the  Securities  Act, the
Exchange Act and the rules and regulations of the SEC thereunder.

                (c) The Company hereby covenants and agrees with Parent that the
Proxy  Statement (at the time it is first mailed to  shareholders of the Company
and at the time of the Company  Meeting) will not contain an untrue statement of
a material fact or omit to state a material  fact required to be stated  therein
or  necessary  in  order  to  make  the  statements  therein,  in  light  of the
circumstances under which they are made, not misleading (provided, however, that
this clause (c) shall apply only to information contained in the Proxy Statement
that was supplied by the Company for inclusion  therein).  If, at any time prior
to the Company Meeting,  any event with respect to the Company,  or with respect
to  other  information  supplied  by the  Company  for  inclusion  in the  Proxy
Statement,  occurs and such event is required to be described in a supplement to
the Proxy Statement, the Company shall promptly notify Parent of such occurrence
and shall promptly prepare, file and disseminate such supplement.

                (d) Parent hereby covenants and agrees with the Company that the
Proxy  Statement (at the time it is first mailed to  shareholders of the Company
and at the time of the Company  Meeting) will not contain an untrue statement of
a material fact or omit to state a material  fact required to be stated  therein
or  necessary  in  order  to  make  the  statements  therein,  in  light  of the
circumstances under which they are made, not misleading (provided, however, that
this clause (d) shall not apply to information  contained in the Proxy Statement
that was supplied by the Company for inclusion  therein).  If, at any time prior
to the Company  Meeting,  any event with  respect to Parent,  or with respect to
other  information  supplied  by Parent for  inclusion  in the Proxy  Statement,
occurs and such event is required to be described  in a supplement  to the Proxy
Statement, Parent shall promptly notify the Company of such occurrence and shall
cooperate with the Company in the preparation,  filing and dissemination of such
supplement.

                (e) Neither the Proxy  Statement nor any amendment or supplement
thereto will be filed or disseminated to the shareholders of the Company without
the approval of both Parent and the Company.  The Company  shall advise  Parent,
promptly after it receives notice thereof,  of the time when the Proxy Statement
has  been  cleared  by the SEC,  or any  comments  or  requests  for  additional
information received from the SEC, whether orally or in writing, with respect to
the Proxy Statement.

         5.7 Additional Arrangements. Subject to the terms and conditions herein
provided,  each of the Company and Parent shall take, or cause to be taken,  all
action and shall do, or cause to be done, all things  necessary,  appropriate or
desirable  under  any  applicable  laws  and  regulations  or  under  applicable
governing   agreements  to  consummate  and  make  effective  the   transactions
contemplated by this Agreement, including using all reasonable efforts to obtain
all  necessary  waivers,  consents and  approvals  and  effecting  all necessary
registrations  and filings.  Each of the Company and Parent shall take, or cause
to be taken, all action or shall do, or cause to be done, all things  necessary,
appropriate or desirable to cause the covenants and conditions applicable to the
transactions  contemplated  hereby  to be  performed  or  satisfied  as  soon as
practicable.  In addition,  if any Governmental  Authority shall have issued any
order, decree,  ruling or injunction,  or taken any other action that would have
the effect of restraining,  enjoining or otherwise prohibiting or preventing the
consummation of the transactions  contemplated  hereby,  each of the Company and
Parent shall use its reasonable best efforts to have such order, decree,  ruling
or injunction or other action declared ineffective as soon as practicable.

         5.8 Public Announcements.  Prior to the Closing, the Company and Parent
will  consult  with each other  before  issuing any press  release or  otherwise
making any public  statement with respect to the  transactions  contemplated  by
this  Agreement  and shall not issue  any such  press  release  or make any such
public  statement  prior to obtaining  the  approval of the other  Party,  which
approval  shall  not be  unreasonably  withheld;  provided,  however,  that such
approval shall not be required where such release or announcement is required by
applicable law or exchange or NASDAQ rule or regulation;  and provided  further,
that  either  the  Company or Parent may  respond to  inquiries  by the press or
others  regarding the  transactions  contemplated by this Agreement,  so long as
such  responses  are  consistent  with  such  Party's  previously  issued  press
releases.

         5.9  Notification  of Certain  Matters.  The Company  shall give prompt
notice to Parent of any of the  following:  (a) any  representation  or warranty
contained in Article 3 being untrue or inaccurate  when made; (b) the occurrence
of any event or development that would cause (or could reasonably be expected to
cause) any  representation  or warranty  contained  in Article 3 to be untrue or
inaccurate  on the  Closing  Date;  and (c) any failure of the Company to comply
with or satisfy any  covenant,  condition or  agreement  to be complied  with or
satisfied by it hereunder. Parent shall give prompt notice to the Company of any
of the  following:  (x) any  representation  or warranty  contained in Article 4
being  untrue  or  inaccurate  when  made;  (y) the  occurrence  of any event or
development  that would  cause (or could  reasonably  be  expected to cause) any
representation or warranty  contained in Article 4 to be untrue or inaccurate on
the  Closing  Date;  and (z) any failure of Parent to comply with or satisfy any
covenant,  condition  or  agreement  to be  complied  with  or  satisfied  by it
hereunder.

         5.10  Payment  of  Expenses.  Each  Party  shall  pay its own  expenses
incident to preparing for, entering into and carrying out this Agreement and the
consummation of the transactions  contemplated hereby, whether or not the Merger
shall be consummated. The Company shall bear and pay: (a) the fee for filing the
Proxy Statement with the SEC and the costs and expenses associated with printing
the Proxy Statement and complying with any applicable  state securities or "blue
sky" laws;  and (b) the costs and  expenses  associated  with  mailing the Proxy
Statement to the  shareholders  of the Company,  and soliciting the votes of the
shareholders of the Company.

         5.11   Indemnification and Insurance.

                (a)   Parent   and  the   Company   agree  that  all  rights  to
indemnification  now existing in favor of any  officers,  directors,  employees,
controlling  shareholders or agents of the Company,  as provided in its charters
or   bylaws   (or   similar   organizational   documents),   and  any   existing
indemnification  agreements or  arrangements  of the Company,  shall survive the
Merger and shall continue in full force and effect for a period of not less than
six years from the  Effective  Time (or such longer period as may be provided in
any existing  indemnification  agreement between the Company, and any current or
former officer or director thereof);  provided,  that, in the event any claim or
claims  are  asserted  or made  within  such  six-year  period,  all  rights  to
indemnification  in  respect of any such claim or claims  shall  continue  until
final disposition of any and all such claims.


                (b) From and after the Effective Time, the Surviving Corporation
shall, for a period of six years after the Effective Time, indemnify, defend and
hold  harmless each person who is now, or has been at any time prior to the date
of this  Agreement  or who  becomes  prior to the  Effective  Time,  an officer,
director,   employee,   controlling   shareholder   or  agent  of  the   Company
(collectively,   the  "Indemnified   Parties")  against  all  losses,   expenses
(including attorneys' fees), claims,  damages,  liabilities and amounts that are
paid in settlement with the approval of the  indemnifying  party (which approval
shall not be  unreasonably  withheld) of, or otherwise in connection  with,  any
threatened  or actual  claim,  action,  suit,  proceeding  or  investigation  (a
"Claim"), based in whole or in part on or arising in whole or in part out of the
fact that the  Indemnified  Party (or the person  controlled by the  Indemnified
Party) is or was a director, officer, employee, controlling shareholder or agent
of the Company (including a trustee or fiduciary of any Company Employee Benefit
Plan) and  pertaining  to any  matter  existing  or  arising  out of  actions or
omissions  occurring  at or prior to the  Effective  Time  (including  any Claim
arising out of this Agreement or any of the transactions  contemplated  hereby),
whether  asserted or claimed prior to, at or after the  Effective  Time, in each
case to the fullest  extent  permitted  under  Oklahoma  law,  and shall pay any
expenses, as incurred, in advance of the final disposition of any such action or
proceeding  to each  Indemnified  Party to the fullest  extent  permitted  under
Oklahoma  law.  In  determining  whether an  Indemnified  Party is  entitled  to

                                      A-34

<PAGE>



indemnification under this Section 5.11, if requested by such Indemnified Party,
such determination shall be made by special, independent counsel selected by the
Surviving  Corporation  and approved by the  Indemnified  Party (which  approval
shall  not be  unreasonably  withheld),  and  who has  not  otherwise  performed
services for the Surviving  Corporation or any of its Affiliates within the last
three years (other than in connection with such matters).  Without  limiting the
foregoing,  in the event any such Claim is brought against any Indemnified Party
or  Parties  (whether  arising  before or after the  Effective  Time):  (i) such
Indemnified  Party or Parties may retain the Surviving  Corporation's  regularly
engaged independent legal counsel or counsel satisfactory to them and reasonably
satisfactory to the Surviving  Corporation,  and the Surviving Corporation shall
pay all reasonable fees and expenses of such counsel for the  Indemnified  Party
or Parties  as  promptly  as  statements  therefor  are  received;  and (ii) the
Surviving  Corporation  will use all  reasonable  best  efforts to assist in the
vigorous  defense of any such matter,  provided that the  Surviving  Corporation
shall  not be liable  for any  settlement  effected  without  its prior  written
consent,  which consent shall not unreasonably be withheld.  In the event of any
Claim,  any  Indemnified  Party wishing to claim  indemnification  will promptly
notify the Surviving  Corporation  thereof (provided,  that failure to so notify
the  Surviving  Corporation  will not affect the  obligations  of the  Surviving
Corporation except to the extent that the Surviving  Corporation shall have been
prejudiced  as a result of such  failure)  and shall  deliver  to the  Surviving
Corporation  the  undertaking  contemplated  by  Section  1031 of the OGCA,  but
without  any  requirement  for the  posting  of a  bond.  Without  limiting  the
foregoing, in the event any such Claim is brought against any of the Indemnified
Parties,  such  Indemnified  Party or Parties may retain only one law firm (plus
one local  counsel,  if necessary)  to represent  them with respect to each such
matter  unless the use of counsel  chosen to represent the  Indemnified  Parties
would present such counsel with a conflict of interest, or the representation of
all of the Indemnified Parties by the same counsel would be inappropriate due to
actual  or  potential  differing  interests  between  them,  in which  case such
additional counsel as may be required (as shall be reasonably  determined by the
Indemnified  Parties  and the  Surviving  Corporation)  may be  retained  by the
Indemnified Parties at the cost and expense of the Surviving Corporation and the
Surviving Corporation shall pay all reasonable fees and expenses of such counsel
for such Indemnified Parties.  The Surviving  Corporation shall use such counsel
for such Indemnified Parties. The Surviving Corporation shall use all reasonable
best efforts to assist in the vigorous defense of any such Claim; provided, that
the  Surviving  Corporation  shall not be  liable  for any  settlement  effected
without its written consent,  which consent,  however, shall not be unreasonably
withheld.  Notwithstanding the foregoing, nothing contained in this Section 5.11

Corporation  may  substitute  therefor  policies  of at least the same  coverage
containing  terms  and  conditions  which  are no less  advantageous;  (ii) such

the last annual  premium paid by the Company prior to the date hereof and if the

                (b) By either  the  Company or Parent if: (i) the Merger has not

qualification shall not be further qualified hereby, and provided, further, that
Parent shall not be entitled to terminate this Agreement pursuant to this clause
(i) unless  Parent has given the  Company  notice of such breach and the Company

event not later than February 28, 2001), and the condition  described in Section
6.2(a), other than the provision thereof relating to the certificate signed by a
Responsible  Officer of the Company,  would not be satisfied if the Closing were
to  occur  on  the  day on  which  Parent  gives  the  Company  notice  of  such

termination;  or (ii) the Company has failed to comply in any  material  respect
with any of its  covenants or  agreements  contained in this  Agreement and such
failure has not been, or cannot be, cured within 10 days after notice and demand

material respect of the representations and warranties made by Parent and Merger
Sub in  Article  4  (provided,  however,  that any  representation  or  warranty
contained  therein  that is qualified  by a  materiality  standard or a Material
Adverse  Effect  qualification  shall  not  be  further  qualified  hereby,  and
provided,  further,  that the Company  shall not be entitled to  terminate  this
Agreement pursuant to this clause (i) unless the Company has given Parent notice
of such  breach  and  Parent  has  failed  to cure  such  breach  within 10 days
following such notice,  but in any event not later than February 28, 2001),  and
the condition  described in Section  6.3(a),  other than the  provision  thereof
relating to the certificate signed by a Responsible Officer of Parent, would not
be satisfied if the Closing were to occur on the day on which the Company  gives
Parent  notice of such  termination;  or (ii) Parent or Merger Sub has failed to
comply  in  any  material  respect  with  any  of its  respective  covenants  or
agreements  contained in this Agreement,  and, in either such case, such failure
has not been,  or cannot be,  cured  within 10 days after  notice and demand for
cure thereof, but in any event not later than February 28, 2001;

                (e) By Parent if (i) the Board of Directors of the Company shall
have failed to recommend  adoption of the Company Proposal at the time the Proxy
Statement is first mailed to  shareholders  of the Company or shall have amended
or withdrawn any such  recommendation and such  recommendation is not reinstated
in its prior form within two business days after such amendment or withdrawal or
(ii) the Company  Meeting does not occur for any reason  (other than as a result
of a breach of this  Agreement  by  Parent)  prior to  February  26,  2001 or is
adjourned beyond such date;

                (f) By Parent  if from and  after  June 30,  2000,  the  Company
should suffer or incur any Material Adverse Effect; or

                (g) By the  Company  upon  receipt  of a  Financing  Termination
Notice if Parent is unable to obtain  replacement  Financing within ten business
days  thereafter  (but in any event not later than  February  24, 2001) on terms
that  provide for no greater  conditions  than those  contained  in the original
Financing  Commitments;  provided,  however,  that such right to terminate  this
Agreement  must be exercised by the Company  within five business days after the
expiration of the above-referenced 10-business-day period.

         7.2 Effect of  Termination.  If this  Agreement is terminated by either
the Company or Parent  pursuant to the provisions of Section 7.1, this Agreement
shall forthwith become void except for, and there shall be no further obligation

therein),  5.6(c),  5.6(d),  5.8, 5.10, 7.3,  Article 8 and the  Confidentiality
Agreement  shall survive any such  termination  and shall  continue  pursuant to
their terms;  provided,  however, that a termination of this Agreement shall not
relieve any Party hereto from any liability for damages  incurred as a result of
a breach by such Party of its representations, warranties, covenants, agreements
or other obligations  hereunder  occurring prior to such  termination;  provided
further,  that in the event of a  termination  of this  Agreement by the Company
pursuant  to  Section  7.1(g),  Parent  and  Merger  Sub shall be deemed to have
committed a material breach of this Agreement  unless the cause of the Financing
Termination  Notice and Parent's  inability to obtain  replacement  Financing as
contemplated  by Section 7.1(g) is due to a failure to fulfill the condition set
forth in Section 6.2(e).

         7.3 Fees and  Expenses.  If this  Agreement is  terminated  pursuant to
Section 7.1(e) or clause (iii) of Section  7.1(b),  the Company shall  promptly,
but in no event later than one business day after termination of this Agreement,
pay to Parent an amount  equal to  $2,000,000  in same day funds and upon making

required  hereby,  the validity,  legality and  enforceability  of the remaining
provisions and obligations contained or set forth herein shall not in any way be
affected or impaired thereby,  unless the foregoing  inconsistent  action or the

this Agreement,  including any investigation by or on behalf of any Party, shall
be deemed to  constitute a waiver by the Party taking such action of  compliance
with any representations,  warranties, covenants or agreements contained in this
Agreement. The waiver by any Party of a breach of any provision hereof shall not
operate or be  construed  as a waiver of any prior or  subsequent  breach of the
same or any other provisions hereof.

         8.11  Confidentiality  Agreement.  The Confidentiality  Agreement shall
remain in full force and  effect  following  the  execution  of this  Agreement;
provided,  however,  that any standstill provisions contained therein are hereby
waived to the  extent  necessary  for the  Parties to  consummate  the Merger in
accordance with the terms of this Agreement.

         8.12 No  Recourse  Against  Others.  Each of the  following  is  herein
referred to as a "Parent  Affiliate":  (a) any direct or indirect  holder of any
equity interests or securities in Parent (whether  limited or general  partners,
members,  shareholders,  or otherwise), (b) any Affiliate of Parent, and (c) any
director, officer, employee, representative or agent of (i) the Parent of Merger
Sub,  (ii) any  Affiliate  of Parent or Merger  Sub, or (iii) any such holder of
equity  interests or securities  referred to in clause (a) above.  Except to the
extent that a Parent Affiliate is an express  signatory party hereto,  no Parent
Affiliate  shall have any liability or  obligation  of any nature  whatsoever in
connection with or under this Agreement or the transactions contemplated hereby,
and the Company  hereby waives and releases all claims of any such liability and
obligation.

         8.13  Incorporation.  Exhibits  and  Schedules  referred  to herein are
attached hereto and by this reference incorporated herein for all purposes.

         8.14 Specific Performance.  The parties recognize that in the event the
Company  should  refuse to  perform  under  the  provisions  of this  Agreement,
monetary  damages  alone  will not be  adequate.  Parent  and  Merger  Sub shall
therefore be entitled, in addition to any other remedies which may be available,
including  money damages,  to obtain  specific  performance of the terms of this
Agreement.  In the event of any action to enforce this  Agreement  specifically,
the Company hereby waives the defense that there is an adequate remedy at law.

         8.15 Section  1090.3.  The Parties  acknowledge  and represent that the
board of directors of each Party has  approved the terms of this  Agreement  and
the  other  Transaction  Documents  and  the  consummation  of the  transactions
contemplated  herein and therein and that such  approval is sufficient to render
the  restrictions  on business  combinations  set forth in Section 1090.3 of the
OGCA inapplicable to the transactions contemplated by the Transaction Documents.

                           [Stephens Inc. Letterhead]



September 27, 2000


Board of  Directors
Home-Stake  Oil & Gas Company
15 E 5th  Street,  Suite 2800
Tulsa, OK 74103-4311

Gentlemen:

         We have acted as your financial advisor in connection with the proposed
merger of Home-Stake Oil & Gas Company (the  "Company") and a merger  subsidiary
of Cortez Oil & Gas, Inc. (the "Transaction") pursuant to which the shareholders
of the  Company  would  receive  cash  consideration  of $11.00 per share of the
Company's  common stock (the "Common  Stock").  The terms and  conditions of the
Transaction  are more fully set forth in the draft of the  Agreement and Plan of
Merger dated September 25, 2000.

         You have  requested our opinion as to the fairness to the  shareholders
of the  Company  from a  financial  point  of  view of the  consideration  to be
received by the shareholders in the Transaction.

         In connection with rendering our opinion we have:

         (i)      analyzed certain publicly available  financial  statements and
                  reports regarding the Company;

         (ii)     reviewed  certain  internal  financial  statements  and  other
                  financial and operating data including the Company's  December
                  31, 1999 reserve engineering report prepared by management;

         (iii)    reviewed with  management the results of the Company's  recent
                  exploration activities;

         (iv)     reviewed  the  reported  prices and trading  activity  for the
                  Common Stock;

         (v)      compared  the  financial  performance  of the  Company and the
                  prices and trading  activity of the Common  Stock with that of
                  certain other comparable companies and their securities;

         (vi)     reviewed  the  financial   terms,   to  the  extent   publicly
                  available, of certain comparable transactions;

         (vii)    reviewed a draft of the  Agreement  and Plan of Merger,  dated
                  September 25, 2000 and related documents;

         (viii)   discussed with management of the Company the operations of and
                  future business prospects for the Company;

         (ix)     assisted in your deliberations regarding the material terms of
                  the Transaction; and

         (x)      performed such other analyses and provided such other services
                  as we have deemed appropriate.

         We have relied on the accuracy and  completeness of the information and
financial data provided to us by the Company, and our opinion is based upon such
information.  We have  inquired into the  reliability  of such  information  and
financial  data only to the limited  extent  necessary  to provide a  reasonable
basis  for our  opinion,  recognizing  that we are  rendering  only an  informed

                                      B-1
<PAGE>



opinion and not an  appraisal  or  certification  of value.  With respect to the
financial  projections and the Company's  December 31, 1999 reserve  engineering
report  prepared by  management  of the Company,  we have assumed that they have
been  reasonably  prepared on bases  reflecting the Company's best estimates and
judgments then available as to the future financial performance of the Company.

         As part of our investment banking business, we regularly issue fairness
opinions and are  continually  engaged in the  valuation of companies  and their
securities in  connection  with business  reorganizations,  private  placements,
negotiated  underwritings,  mergers and  acquisitions and valuations for estate,
corporate and other  purposes.  We are familiar with the Company and  previously
have  provided  investment  banking  services to it. In the  ordinary  course of
business,  Stephens  Inc. and its  affiliates at any time may hold long or short
positions,  and may trade or otherwise  effect  transactions as principal or for
the accounts of customers, in the equity securities of the Company.  Stephens is
receiving a fee and reimbursement of its expenses in connection with our work as
financial advisor to the Company, most of which is due upon consummation of this
transaction.

         Based  on the  foregoing  and  our  general  experience  as  investment
bankers, and subject to the qualifications  stated herein, we are of the opinion
on the date hereof that the  consideration to be received by the shareholders of
the Company in the Transaction is fair to them from a financial point of view.

         This opinion and a summary  discussion of our  underlying  analyses and
role  as  your  financial  advisor  may be  included  in  communications  to the
Company's  shareholders  provided that we approve of such  disclosures  prior to
publication.


Very truly yours,

/s/ Stephens Inc.

STEPHENS INC.

          TEXT OF SECTION 1091 OF THE OKLAHOMA GENERAL CORPORATION ACT
             CONCERNING APPRAISAL RIGHTS OF DISSENTING SHAREHOLDERS


ss. 1091. Appraisal Rights

APPRAISAL RIGHTS

         A. Any  shareholder  of a corporation of this state who holds shares of
stock on the  date of the  making  of a demand  pursuant  to the  provisions  of
subsection D of this section with respect to the shares,  who continuously holds
the shares  through the effective date of the merger or  consolidation,  who has
otherwise  complied with the  provisions of subsection D of this section and who
has neither voted in favor of the merger or consolidation  nor consented thereto
in writing  pursuant to the  provisions  of Section  1073 of this title shall be
entitled to an appraisal  by the district  court of the fair value of the shares
of stock  under  the  circumstances  described  in  subsections  B and C of this
section.  As used in this  section,  the word  "shareholder"  means a holder  of
record of stock in a stock corporation and also a member of record of a nonstock
corporation;  the words  "stock" and "share" mean and include what is ordinarily
meant by those words and also membership or membership interest of a member of a
nonstock  corporation;  and "depository receipt" means an instrument issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation,  which stock is deposited with the depository.
The  provisions  of this  subsection  shall be  effective  only with  respect to
mergers or  consolidations  consummated  pursuant to an  agreement  of merger or
consolidation entered into after November 1, 1988.

         B. 1. Except as otherwise  provided for in this  subsection,  appraisal
         rights  shall be  available  for the  shares  of any class or series of
         stock of a constituent corporation in a merger or consolidation,  or of
         the  acquired  corporation  in a  share  acquisition,  to  be  effected
         pursuant  to the  provisions  of  Section  1081,  other  than a  merger
         effected  pursuant to subsection G of Section 1081,  and Sections 1082,
         1086, 1087, 1090.1 or 1090.2 of this title.

                  2.  a.  No  appraisal  rights  under  this  section  shall  be
         available  for the shares of any class or series of stock which  stock,
         or depository  receipts in respect thereof, at the record date fixed to
         determine the shareholders entitled to receive notice of and to vote at
         the  meeting of  shareholders  to act upon the  agreement  of merger or
         consolidation, were either:

                           (1)  listed  on a  national  securities  exchange  or
                  designated  as  a  national   market  system  security  on  an
                  interdealer  quotation  system by the National  Association of
                  Securities Dealers, Inc.; or

                           (2) held of record by more than two thousand holders.

         No appraisal  rights shall be available  for any shares of stock of the
         constituent  corporation  surviving  a  merger  if the  merger  did not
         require for its approval the vote of the  shareholders of the surviving
         corporation as provided in subsection G of Section 1081 of this title.

                  b. In addition, no appraisal rights shall be available for any
         shares of stock,  or  depository  receipts in respect  thereof,  of the
         constituent  corporation  surviving  a  merger  if the  merger  did not
         require for its approval the vote of the  shareholders of the surviving
         corporation  as provided  for in  subsection  F of Section 1081 of this
         title.

                  3.  Notwithstanding  the  provisions  of  paragraph  2 of this
         subsection,  appraisal  rights  provided for in this  section  shall be
         available  for  the  shares  of any  class  or  series  of  stock  of a
         constituent  corporation  if the holders  thereof  are  required by the
         terms of an  agreement  of  merger  or  consolidation  pursuant  to the
         provisions of Sections 1081, 1082, 1086, 1087, 1090.1 or 1090.2 of this
         title to accept for the stock anything except:

                  a. shares of stock of the  corporation  surviving or resulting
         from the merger or consolidation or depository receipts thereof, or

                  b.  shares of stock of any other  corporation,  or  depository
         receipts  in  respect  thereof,  which  shares  of stock or  depository
         receipts at the effective date of the merger or  consolidation  will be
         either  listed on a national  securities  exchange or  designated  as a
         national market system security on an interdealer  quotation  system by
         the National Association of Securities Dealers,  Inc. or held of record
         by more than two thousand holders, or

                  c. cash in lieu of fractional shares or fractional  depository
         receipts described in subparagraphs a and b of this paragraph, or

                  d.  any  combination  of  the  shares  of  stock,   depository
         receipts,  and  cash in lieu of the  fractional  shares  or  depository
         receipts described in subparagraphs a, b, and c of this paragraph.

                  4. In the  event  all of the  stock of a  subsidiary  Oklahoma
         corporation  party to a merger  effected  pursuant to the provisions of
         Section  1083 of this  title  is not  owned by the  parent  corporation
         immediately  prior to the merger,  appraisal  rights shall be available
         for the shares of the subsidiary Oklahoma corporation.

         C. Any corporation may provide in its certificate of incorporation that
appraisal  rights  under this section  shall be available  for the shares of any
class or series of its stock as a result of an amendment to its  certificate  of
incorporation,  any  merger  or  consolidation  in which  the  corporation  is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation.  If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections D and E
of this section, shall apply as nearly as is practicable.

         D.       Appraisal rights shall be perfected as follows:

                  1. If a proposed merger or  consolidation  for which appraisal
         rights are provided  under this section is to be submitted for approval
         at a meeting of  shareholders,  the  corporation,  not less than twenty
         (20) days prior to the meeting,  shall notify each of its  shareholders
         entitled to appraisal  rights that  appraisal  rights are available for
         any or all of the  shares of the  constituent  corporations,  and shall
         include in the notice a copy of this section. Each shareholder electing
         to demand the appraisal of the shares of the shareholder  shall deliver
         to the  corporation,  before  the  taking of the vote on the  merger or
         consolidation,  a written  demand  for  appraisal  of the shares of the
         shareholder. The demand will be sufficient if it reasonably informs the
         corporation of the identity of the shareholder and that the shareholder
         intends   thereby  to  demand  the  appraisal  of  the  shares  of  the
         shareholder.  A proxy or vote against the merger or consolidation shall
         not  constitute  such a demand.  A  shareholder  electing  to take such
         action  must do so by a  separate  written  demand as herein  provided.
         Within  ten  (10)  days  after  the  effective  date of the  merger  or
         consolidation, the surviving or resulting corporation shall notify each
         shareholder of each  constituent  corporation who has complied with the
         provisions  of this  subsection  and  has  not  voted  in  favor  of or
         consented to the merger or consolidation as of the date that the merger
         or consolidation has become effective; or



                                       C-2

<PAGE>



                  2. If the merger or consolidation is approved  pursuant to the
         provisions  of Section  1073 or 1083 of this  title,  each  constituent
         corporation,  either  before  the  effective  date  of  the  merger  or
         consolidation or within ten (10) days thereafter,  shall notify each of
         the  holders  of any  class or  series  of  stock  of such  constituent
         corporation who are entitled to appraisal rights of the approval of the
         merger or consolidation and that appraisal rights are available for any
         or all of the shares of the class or series of stock of the constituent
         corporation,  and shall  include in such notice a copy of this section;
         provided,  if the notice is given on or after the effective date of the
         merger or consolidation,  the notice shall be given by the surviving or
         resulting  corporation  to all the  holders  of any  class or series of
         stock of a  constituent  corporation  that are  entitled  to  appraisal
         rights. The notice may, and, if given on or after the effective date of
         the merger or consolidation, shall, also notify the shareholders of the
         effective date of the merger or consolidation. Any shareholder entitled
         to  appraisal  rights  may,  within  twenty (20) days after the date of
         mailing  of the  notice,  demand  in  writing  from  the  surviving  or
         resulting  corporation the appraisal of the holder's shares. The demand
         will be  sufficient  if it reasonably  informs the  corporation  of the
         identity of the shareholder and that the shareholder  intends to demand
         the  appraisal  of the holder's  shares.  If the notice does not notify
         shareholders  of the  effective  date of the  merger  or  consolidation
         either:

                  a. each  constituent  corporation  shall send a second  notice
         before the effective date of the merger or consolidation notifying each
         of the  holders  of any  class or  series  of stock of the  constituent
         corporation that are entitled to appraisal rights of the effective date
         of the merger or consolidation, or

                  b. the surviving or resulting  corporation shall send a second
         notice to all  holders on or within  ten (10) days after the  effective
         date of the merger or  consolidation;  provided,  however,  that if the
         second notice is sent more than twenty (20) days  following the mailing
         of the  first  notice,  the  second  notice  need  only be sent to each
         shareholder  who is entitled to  appraisal  rights and who has demanded
         appraisal of the holder's shares in accordance with this subsection. An
         affidavit of the  secretary  or assistant  secretary or of the transfer
         agent of the  corporation  that is required to give either  notice that
         the notice  has been given  shall,  in the  absence of fraud,  be prima
         facie evidence of the facts stated therein. For purposes of determining
         the  shareholders  entitled to receive either notice,  each constituent
         corporation  may fix, in advance,  a record date that shall be not more
         than ten (10) days prior to the date the notice is given;  provided, if
         the  notice is given on or after the  effective  date of the  merger or
         consolidation,  the record  date  shall be the  effective  date.  If no
         record  date is fixed and the  notice is given  prior to the  effective
         date,  the record  date shall be the close of  business on the day next
         preceding the day on which the notice is given.

         E. Within one hundred twenty (120) days after the effective date of the
merger  or  consolidation,   the  surviving  or  resulting  corporation  or  any
shareholder  who has complied with the provisions of subsections A and D of this
section and who is otherwise  entitled to appraisal rights,  may file a petition
in district  court  demanding a  determination  of the value of the stock of all
such shareholders;  provided,  however, at any time within sixty (60) days after
the effective date of the merger or  consolidation,  any shareholder  shall have
the right to withdraw the demand of the  shareholder for appraisal and to accept
the terms offered upon the merger or  consolidation.  Within one hundred  twenty
(120)  days  after  the  effective  date of the  merger  or  consolidation,  any
shareholder  who has complied with the  requirements  of  subsections A and D of
this  section,  upon  written  request,  shall be entitled  to receive  from the
corporation surviving the merger or resulting from the consolidation a statement
setting forth the aggregate number of shares not voted in favor of the merger or
consolidation and with respect to which demands for appraisal have been received
and the aggregate number of holders of the shares.  The written  statement shall
be mailed  to the  shareholder  within  ten (10)  days  after the  shareholder's
written  request for a  statement  is received  by the  surviving  or  resulting
corporation or within ten (10) days after  expiration of the period for delivery
of demands for  appraisal  pursuant to the  provisions  of  subsection D of this
section, whichever is later.

         F. Upon the filing of any such petition by a shareholder,  service of a
copy thereof shall be made upon the surviving or resulting  corporation,  which,
within  twenty (20) days after  service,  shall file, in the office of the court
clerk of the district  court in which the petition  was filed,  a duly  verified
list  containing the names and addresses of all  shareholders  who have demanded


                                       C-3

<PAGE>



payment for their shares and with whom  agreements  regarding the value of their
shares have not been reached by the surviving or resulting  corporation.  If the
petition shall be filed by the surviving or resulting corporation,  the petition
shall be accompanied by such duly verified list. The court clerk,  if so ordered
by the court,  shall give  notice of the time and place fixed for the hearing on
the  petition by  registered  or  certified  mail to the  surviving or resulting
corporation and to the shareholders  shown on the list at the addresses  therein
stated.  Notice shall also be given by one or more publications at least one (1)
week  before the day of the  hearing,  in a  newspaper  of  general  circulation
published in the City of Oklahoma City,  Oklahoma,  or other  publication as the
court deems advisable. The forms of the notices by mail and by publication shall
be approved by the court,  and the costs thereof shall be borne by the surviving
or resulting corporation.

         G. At the  hearing  on the  petition,  the court  shall  determine  the
shareholders  who have complied with the provisions of this section and who have
become entitled to appraisal rights.  The court may require the shareholders who
have  demanded an appraisal of their  shares and who hold stock  represented  by
certificates  to  submit  their  certificates  of stock to the  court  clerk for
notation  thereon  of the  pendency  of the  appraisal  proceedings;  and if any
shareholder  fails to comply  with this  direction,  the court may  dismiss  the
proceedings as to that shareholder.

         H. After  determining the  shareholders  entitled to an appraisal,  the
court shall appraise the shares,  determining  their fair value exclusive of any
element of value arising from the accomplishment or expectation of the merger or
consolidation,  together  with a fair rate of interest,  if any, to be paid upon
the amount  determined to be the fair value. In determining the fair value,  the
court shall take into account all relevant factors. In determining the fair rate
of interest, the court may consider all relevant factors,  including the rate of
interest  which the  surviving  or  resulting  corporation  would have to pay to
borrow money  during the pendency of the  proceeding.  Upon  application  by the
surviving or resulting corporation or by any shareholder entitled to participate
in the appraisal proceeding, the court may, in its discretion,  permit discovery
or other pretrial  proceedings and may proceed to trial upon the appraisal prior
to the final  determination  of the  shareholder  entitled to an appraisal.  Any
shareholder  whose name appears on the list filed by the  surviving or resulting
corporation  pursuant to the  provisions of subsection F of this section and who
has submitted the  certificates  of stock of the shareholder to the court clerk,
if  required,  may  participate  fully in all  proceedings  until it is  finally
determined that the shareholder is not entitled to appraisal  rights pursuant to
the provisions of this section.

         I. The court shall  direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
shareholders entitled thereto.  Interest may be simple or compound, as the court
may direct. Payment shall be made to each shareholder, in the case of holders of
uncertificated  stock  immediately,  and  in  the  case  of  holders  of  shares
represented  by  certificates  upon  the  surrender  to the  corporation  of the
certificates representing the stock. The court's decree may be enforced as other
decrees  in the  district  court  may be  enforced,  whether  the  surviving  or
resulting corporation be a corporation of this state or of any other state.

         J. The costs of the proceeding may be determined by the court and taxed
upon the  parties  as the  court  deems  equitable  in the  circumstances.  Upon
application  of a  shareholder,  the court  may  order  all or a portion  of the
expenses   incurred  by  any   shareholder  in  connection  with  the  appraisal
proceeding,  including,  without limitation,  reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all of
the shares entitled to an appraisal.

         K. From and after the effective date of the merger or consolidation, no
shareholder who has demanded appraisal rights as provided for in subsection D of
this  section  shall be entitled to vote the stock for any purpose or to receive
payment of dividends or other  distributions  on the stock,  except dividends or
other  distributions  payable to shareholders of record at a date which is prior
to the effective date of the merger or consolidation; provided, however, that if
no petition  for an  appraisal  shall be filed  within the time  provided for in
subsection  E of  this  section,  or if the  shareholder  shall  deliver  to the
surviving or resulting  corporation a written  withdrawal  of the  shareholder's
demand for an appraisal and an acceptance of the merger or consolidation, either

within sixty (60) days after the effective  date of the merger or  consolidation
as provided for in subsection E of this section or  thereafter  with the written
approval of the  corporation,  then the right of the shareholder to an appraisal
shall cease;  provided  further,  no appraisal  proceeding in the district court
shall be dismissed as to any shareholder  without the approval of the court, and
approval may be conditioned upon terms as the court deems just.

         L. The shares of the surviving or resulting  corporation into which the
shares of any objecting shareholders would have been converted had they assented
to the merger or consolidation  shall have the status of authorized and unissued
shares of the surviving or resulting corporation.
