     After careful consideration, the Board of Directors of HSOG has determined
that the proposed Merger is fair to and in the best interests of HSOG and its
stockholders.  Accordingly, the Board of Directors has unanimously approved the
Merger Agreement and recommends that all stockholders vote for its approval.
The Board of Directors has also determined that the proposed changes to HSOG's
Certificate of Incorporation and adoption of the HSOG 1997 Incentive Stock Plan
are in the best interests of HSOG and its stockholders and unanimously

                HSRC Common Stock); and

                (d) each stockholder of HSOG (other than HSRC and HSOG

         Proxy Statement and Prospectus. The terms of the Merger Agreement also

         increase the authorized capital stock in order to effect and facilitate
         the Merger and stock split.

                              --------------------

                        THE HOME-STAKE OIL & GAS COMPANY
                                   PROSPECTUS

                              --------------------

     This Joint Proxy Statement and Prospectus (this "Proxy
Statement/Prospectus") is furnished in connection with the solicitation of
proxies by the Boards of Directors of The Home-Stake Oil & Gas Company, an
Oklahoma corporation ("HSOG"), and The Home-Stake Royalty Corporation, an
Oklahoma corporation ("HSRC"), for use in connection with the Special Meeting of
Stockholders of HSOG (the "HSOG Meeting") and the Special Meeting of
Stockholders of HSRC (the "HSRC Meeting"), respectively, each of which is to be
held on November 20, 1997, or any adjournment or postponement thereof. At such
meetings, the stockholders of each of HSOG and HSRC will consider and vote upon
a proposal to approve and adopt an Agreement of Merger dated as of August 14,
1997 (the "Merger Agreement"), between HSOG and HSRC, pursuant to which, among
other things, (i) HSRC will be merged with and into HSOG (the "Merger") and 
(ii) the shares of Common Stock, $20.00 par value per share, of HSOG ("HSOG
Common Stock") will be split on a 30-for-1 basis (the common stock resulting
from such stock split is hereinafter referred to as "New HSOG Common Stock"). As
a result of the Merger, each of the then outstanding shares of Common Stock,
$40.00 par value per share, of HSRC ("HSRC Common Stock") (other than shares
held by HSOG which will be cancelled) will be converted into the right to
receive 48.66 shares of New HSOG Common Stock (representing approximately 1.62
shares of HSOG Common Stock prior to the 30-for-1 stock split for each share of
HSRC Common Stock) (subject to appraisal rights for dissenting HSRC
stockholders) and each of the then outstanding shares of HSOG Common Stock
(other than shares held by HSRC which will be cancelled) will be converted into
the right to receive 30 shares of New HSOG Common Stock (subject to appraisal
rights for dissenting HSOG stockholders).

     Also, the stockholders of HSOG will consider and vote upon proposals to
approve certain amendments to the HSOG Certificate of Incorporation and the HSOG
1997 Incentive Stock Plan, and the stockholders of both HSOG and HSRC will
transact such other business as may properly come before the meetings or any
adjournment or postponement thereof.

     This Proxy Statement/Prospectus also constitutes a prospectus of HSOG with
respect to up to approximately 2,742,203 shares of New HSOG Common Stock to be
issued to the stockholders of HSRC pursuant to the Merger.

     The securities offered hereby involve a high degree of risk inherent to the
oil and gas industry. See "Risk Factors" commencing on page 12 for a discussion
of certain factors which should be considered in evaluating the Merger.

     This Proxy Statement/Prospectus and the accompanying forms of proxy are
first being mailed to the stockholders of HSOG and HSRC on or about October 13,
1997.

                              --------------------

          The following is a summary of certain information contained elsewhere
     in this Joint Proxy Statement and Prospectus (this "Proxy
     Statement/Prospectus"). This summary does not purport to be complete and is
     qualified in its entirety by reference to the more detailed information
     contained elsewhere in this Proxy Statement/Prospectus, the Appendices
     hereto and the documents referred to herein. Stockholders are urged to

     attached as Appendix A and the other appendices attached hereto. Terms used
     herein with their initial letters capitalized are defined herein, which
     definitions are summarized under "Definition of Certain Terms."

     HSRC

          The Home-Stake Royalty Corporation, an Oklahoma corporation, was
     formed in 1929 and, together with HSOG, is actively engaged in the
     acquisition, exploration, development and production of oil and gas
     properties. HSRC serves as operator of certain producing properties owned
     by HSRC and HSOG. HSRC's principal executive offices are located at 15 East
     5th Street, Suite 2800, Tulsa, Oklahoma 74103, and its telephone number at
     such offices is (918) 583-0178.

     HSOG

          The Home-Stake Oil & Gas Company, an Oklahoma corporation, was formed
     in 1917 and, together with HSRC, is actively engaged in the acquisition,
     exploration, development and production of oil and gas properties. HSOG's
     principal executive offices are located at 15 East 5th Street, Suite 2800,
     Tulsa, Oklahoma 74103, and its telephone number is (918) 583-0178.

     Special Meetings

          This Proxy Statement/Prospectus relates to the Special Meeting of
     Stockholders of HSOG (the "HSOG Meeting") and the Special Meeting of
     Stockholders of HSRC (the "HSRC Meeting").  At the meetings, the
     stockholders of each of HSOG and HSRC will consider and vote upon proposals
     to approve and adopt the Merger Agreement between HSOG and HSRC, pursuant
     to which, among other things, HSRC will be merged with and into HSOG (the
     "Merger") and the Common Stock of HSOG will be split on a 30-for-1 basis
     (the "Stock Split").  With respect to the HSOG Meeting only, HSOG
     stockholders will consider and vote upon eight proposed amendments to the
     HSOG Certificate of Incorporation and upon a proposal to approve the HSOG
     1997 Incentive Stock Plan.  See "Summary--Amendments to the HSOG
     Certificate of Incorporation" below for a complete list of the proposed
     amendments to HSOG's Certificate of Incorporation.

          The HSOG Meeting will be held on November 20, 1997, at 9:00 a.m.,
     Tulsa, in the offices of HSOG at 15 East 5th Street, Suite 2800, Tulsa,
     Oklahoma. The record date for stockholders of HSOG entitled to notice of
     and to vote at the HSOG Meeting is as of the close of business on September
     30, 1997.

          Voting rights for HSOG are vested in the holders of the Common Stock,
     $20.00 par value per share, of HSOG ("HSOG Common Stock"), with each share
     of HSOG Common Stock entitled to one vote on each matter coming before the
     stockholders.  As of July 31, 1997, there were 89,509 shares of HSOG Common
     Stock outstanding, held by approximately 200 holders of record.

          The affirmative vote of the holders of 66 2/3 percent of the
     outstanding shares of HSOG Common Stock is required for the approval and
     adoption of the Merger Agreement. The affirmative vote of the holders of a
     majority of the outstanding shares of HSOG Common Stock is required for the
     approval and adoption of Proposed Amendments Nos. 1, 2 and 5 through 8
     (described in this Summary below under "Amendments to the HSOG Certificate
     of Incorporation") to the HSOG Certificate of Incorporation and

                                      -4-
<PAGE>
 
     the affirmative vote of the holders of 66 2/3 percent of the outstanding
     shares of HSOG Common Stock is required for the approval and adoption of
     Proposed Amendments Nos. 3 and 4 (below) to the HSOG Certificate of
     Incorporation.  See "Amendments to the HSOG Certificate of Incorporation."
     In addition, the affirmative vote of the holders of a majority of the
     shares of HSOG Common Stock present or represented by proxy at the HSOG
     Meeting is required for approval of the HSOG 1997 Incentive Stock Plan.
     HSRC, which owns approximately 33.9 percent of the outstanding shares of
     HSOG Common Stock, intends to vote all such shares of Common Stock in favor
     of the Merger, the amendments to the HSOG Certificate of Incorporation and
     the approval of the HSOG 1997 Incentive Stock Plan.  As of  July 31, 1997,
     directors and executive officers of HSOG and their affiliates were
     beneficial owners of approximately 11.5 percent of the outstanding shares
     of HSOG Common Stock.  All such directors and executive officers have
     indicated that they will vote in favor of the Merger, the amendments to the
     HSOG Certificate of Incorporation and the adoption of the HSOG 1997
     Incentive Stock Plan.

          The HSRC Meeting will be held on November 20, 1997, at 9:00 a.m., in
     the offices of HSRC at 15 East 5th Street, Suite 2800, Tulsa, Oklahoma. The
     record date for stockholders of HSRC entitled to notice of and to vote at
     the HSRC Meeting is as of the close of business on September 30, 1997.

          Voting rights for HSRC are vested in the holders of the Common Stock,
     $40.00 par value per share, of HSRC ("HSRC Common Stock"), with each share
     entitled to one vote on each matter coming before the stockholders.  As of
     July 31, 1997, there were 69,808 shares of HSRC Common Stock outstanding
     held by approximately 300 holders of record.

          The affirmative vote of the holders of 66 2/3 percent of the
     outstanding shares of HSRC Common Stock is required for the approval and
     adoption of the Merger Agreement. HSOG, which owns approximately 19.3
     percent of the outstanding shares of HSRC Common Stock, intends to vote all
     such shares of Common Stock in favor of the Merger. As of July 31, 1997,
     directors and executive officers of HSRC and their affiliates were
     beneficial owners of approximately 20.7 percent of the outstanding shares
     of HSRC Common Stock. All such directors and executive officers have
     indicated that they will vote in favor of the Merger.

     The Merger

          Conversion of HSRC Common Stock. Upon consummation of the transactions
     contemplated by the Merger Agreement:

          . HSRC will be merged with and into HSOG (the "Merger"), and

          . Each issued and outstanding share of HSRC Common Stock (other than
            shares held by HSOG, which will be cancelled, and by holders
            exercising their dissenters' appraisal rights) will be converted
            into the right to receive 48.66 shares of New HSOG Common Stock.

     The conversion of each share of HSRC Common Stock into the right to receive
     48.66 shares of New HSOG Common Stock upon consummation of the Merger (the
     "Exchange Ratio") represents approximately 1.62 shares of HSOG Common Stock
     prior to the Stock Split for each share of HSRC Common Stock.  Fractional
     shares of New HSOG Common Stock will not be issued in connection with the
     Merger.  Any HSRC stockholder otherwise entitled to a fractional share will
     receive a whole share of New HSOG Common Stock in lieu of such fractional
     share.

          Split of HSOG Common Stock. The Merger Agreement provides for the
     split of the shares of HSOG Common Stock on a 30-for-1 basis (the common
     stock resulting from such split is referred to herein as "New HSOG Common
     Stock") as of the effective time of the Merger. At such effective time,
     each issued and outstanding share of HSOG Common Stock (other than shares
     held by HSRC, which

                                      -5-
<PAGE>
 
     will be cancelled, and any holders exercising their dissenters' appraisal
     rights) will be converted into the right to receive 30 shares of New HSOG
     Common Stock.

          Increase in Authorized Shares of HSOG Capital Stock.  Approval of the
     Merger Agreement will also constitute approval of an amendment to the HSOG
     Certificate of Incorporation (the "HSOG Certificate" and, as amended, the
     "Amended HSOG Certificate") set forth in the Certificate of Merger (see
     Appendix D to this Proxy Statement/Prospectus).  The Certificate of Merger
     contains provisions to (i) increase the number of authorized shares of
     HSOG's capital stock to 14,000,000 shares, consisting of 12,000,000 shares
     of Common Stock, par value $0.01 per share, and 2,000,000 shares of
     Preferred Stock, par value $1.00 per share, and (ii) effect the Stock
     Split.  See "Risk Factors--Possible Effect of Authorized Shares of HSOG
     Capital Stock" and "Description of HSOG Capital Stock."

          Reasons for the Merger.  The Boards of Directors of HSOG and HSRC
     believe that the Merger is advisable and in the best interests of the
     stockholders of their respective companies.  The principal reasons for the
     Merger are to (i) consolidate HSRC's assets with the assets of HSOG to
     create a larger and more financially secure entity, (ii) utilize the cash
     flow and borrowing capacity generated by the consolidated assets  for the
     further development of existing properties and the acquisition of
     additional properties, (iii) create a single entity that can access public
     capital markets to raise additional capital for HSOG's business, and (iv)
     provide possibly greater liquidity to the holders of HSOG Common Stock and
     HSRC Common Stock.

          Recommendations of the Boards of Directors.  The Boards of Directors
     of HSOG and HSRC believe that the terms of the Merger are fair to and in
     the best interests of their respective stockholders and each has, by
     unanimous vote, approved the Merger Agreement and each unanimously
     recommends that its stockholders vote FOR approval of the Merger Agreement.
     For a discussion of the factors considered by the Boards of Directors in
     reaching their respective decisions, see "The Merger--Background of and
     Reasons for the Merger."

          Exchange Ratio.  The Exchange Ratio was established by Principal
     Financial Securities, Inc. ("Principal")  based upon the relative estimated
     values of the companies.  The Boards of Directors believe that the Exchange
     Ratio represents a fair allocation of the ownership of the surviving
     company among the current stockholders of both companies.  See "Risk
     Factors--Determination of Exchange Ratio," "The Merger--Determination of
     Exchange Ratio" and "The Merger--Opinion of Financial Advisor."

          Opinion of Financial Advisor.  Principal has delivered its written
     opinion to the Boards of Directors of HSOG and HSRC to the effect that,
     based upon and subject to considerations and assumptions set forth therein
     and based upon such other matters as Principal considered relevant, the
     consideration to be received in the Merger by the stockholders of HSRC was,
     as of the date of its opinion, fair to the disinterested stockholders of
     HSRC and HSOG (i.e. stockholders who are not directors, officers or
     employees of HSRC or HSOG or greater than 15% owners of HSRC Common Stock
     or HSOG Common Stock) from a financial point of view.  A copy of the full
     text of the written opinion of Principal, which sets forth the assumptions
     made, procedures followed, matters considered and limits of its review, is
     attached to this Proxy Statement/Prospectus as Appendix B, and should be
     read carefully in its entirety.  See "The Merger--Opinion of Financial
     Advisor."

          Interests of Certain Persons in the Merger.  In considering the
     recommendations of the Boards of Directors of HSOG and HSRC with respect
     to the Merger Agreement and the transactions contemplated thereby,
     stockholders should be aware that certain members of the management of HSOG
     and HSRC and the Boards of Directors of HSOG and HSRC have certain
     interests in the Merger that are in addition to the interests of
     stockholders of HSOG and HSRC generally.  See "The Merger--Interests of
     Certain Persons in the Merger."

                                      -6-
<PAGE>
 
          Conditions to the Merger.  The obligations of HSOG and HSRC to
     consummate the Merger are subject to obtaining requisite stockholder
     approvals and the satisfaction or waiver of certain conditions, including
     (i) the absence of any injunction prohibiting consummation of the Merger,
     (ii) holders of not more than 12% of the outstanding shares of HSOG Common
     Stock or HSRC Common Stock shall have exercised their appraisal rights
     under Oklahoma law, and (iii) the receipt of an opinion of counsel with
     respect to the tax consequences of the Merger.  See "The Merger Agreement--
     Conditions."

          Effective Time of the Merger.  The Merger will become effective at
     5:00 o'clock p.m., Central Standard Time, on December 31, 1997 (the
     "Effective Time"), in the event the requisite stockholder approvals have
     been obtained and all other conditions to the Merger have been satisfied or
     waived.

          Exchange of HSRC Certificates.  Upon consummation of the Merger, each
     holder (other than HSOG and stockholders who have exercised their
     dissenter's appraisal rights under Oklahoma law) of a certificate or
     certificates representing shares of HSRC Common Stock outstanding
     immediately prior to the Merger will be entitled to receive 48.66 shares
     of New HSOG Common Stock for each share of HSRC Common Stock.  As soon as
     practicable after the Effective Time, HSOG will cause to be mailed to each
     record holder of HSRC Common Stock as of the Effective Time a letter of
     transmittal (the "HSRC Letter of Transmittal") to be used to effect the
     exchange of certificates representing HSRC Common Stock for certificates
     representing New HSOG Common Stock.  If the Merger is approved and
     consummated, each HSRC stockholder (other than those exercising their
     appraisal rights) must surrender the certificate or certificates
     representing such HSRC Common Stock, along with a properly completed and
     executed HSRC Letter of Transmittal and any other required documents.  Only
     then will such HSRC stockholder be entitled to receive a certificate
     representing the whole number of shares of New HSOG Common Stock to which
     such stockholder is entitled.  HSRC stockholders should not surrender their
     stock certificates until the HSRC Letter of Transmittal is received and
     then should surrender their stock certificates only accompanied by a
     properly completed and executed HSRC Letter of Transmittal.  See "The
     Merger Agreement--Exchange Procedures."

          Exchange of HSOG Certificates.  Upon consummation of the Merger and as
     a result of the Stock Split, each holder (other than HSRC and stockholders
     who have exercised their dissenter's appraisal rights under Oklahoma law)
     of a certificate or certificates representing shares of HSOG Common Stock
     outstanding immediately prior to the Merger will be entitled to receive 30
     shares of New HSOG Common Stock for each share of HSOG Common Stock.  As
     soon as practicable after the Effective Time, HSOG will cause to be mailed
     to each record holder of HSOG Common Stock as of the Effective Time a
     letter of transmittal (the "HSOG Letter of Transmittal") to be used to
     effect the exchange of certificates representing HSOG Common Stock for
     certificates representing New HSOG Common Stock.  If the Merger is approved
     and consummated, each HSOG stockholder (other than those exercising their
     appraisal rights) must surrender the certificate or certificates
     representing such HSOG Common Stock, along with a properly completed and
     executed HSOG Letter of Transmittal and any other required documents.  Only
     then will such HSOG stockholder be entitled to receive a certificate
     representing the whole number of shares of New HSOG Common Stock to which
     such stockholder is entitled.  HSOG stockholders should not surrender their
     stock certificates until the HSOG Letter of Transmittal is received and
     then should surrender their stock certificates only accompanied by a
     properly completed and executed HSOG Letter of Transmittal.  See "The
     Merger Agreement--Exchange Procedures."

          Appraisal Rights.  Holders of HSOG Common Stock and HSRC Common Stock
     are entitled to appraisal rights in connection with the Merger.  It is a
     condition to the consummation of the Merger (which condition may be waived
     by HSOG), that holders of not more than 12% of the outstanding shares of
     either HSOG Common Stock or HSRC Common Stock shall have exercised their
     appraisal rights.  See "The Merger--Appraisal Rights" and "The Merger
     Agreement--Conditions."

          Federal Income Tax Consequences.  The Merger and Stock Split are
     intended to qualify as reorganizations under Section 368(a) of the Internal
     Revenue Code of 1986, as amended (the "Code").  Assuming the Merger and
     Stock Split qualify for reorganization treatment, a HSOG or HSRC
     stockholder

                                      -7-
<PAGE>
 
     who receives New HSOG Common Stock pursuant to the Merger and/or Stock
     Split will generally not be subject to federal income taxation with
     respect thereto as described under "The Merger--Federal Income Tax
     Consequences."  The federal income tax consequences described herein are
     for general information only.  HSOG and HSRC stockholders should consult
     their own tax advisors as to the particular consequences of the Merger and
     Stock Split to them, including the application of federal, state, local and
     foreign income and other tax laws.  See "The Merger--Federal Income Tax
     Consequences."

          Accounting Treatment.  The Merger will be accounted for in a manner
     similar to a pooling of interests for accounting and financial reporting
     purposes.  See "The Merger--Accounting Treatment."

          Resale Restrictions.  All shares of New HSOG Common Stock received by
     HSRC stockholders will be freely transferable, except shares received by
     persons who are deemed to be "affiliates" or "underwriters" (as such term
     is defined under the Securities Act) of HSRC prior to the Merger may be
     resold by them only in certain permitted circumstances.  An "affiliate"
     generally includes individuals or entities that control, are controlled by
     or are under common control with, another party and may include certain
     officers, directors and principal stockholders of such party.  See "The
     Merger--Restrictions on Resales by Affiliates of HSRC."

          Comparison of Rights of Security Holders.  See "Comparative Rights of
     Stockholders" for a discussion of the comparative rights of holders of HSOG
     Common Stock, New HSOG Common Stock and HSRC Common Stock.

          NASDAQ Listing.  It is anticipated that the shares of New HSOG Common
     Stock to be issued in the transactions contemplated by the Merger will be
     listed on the NASDAQ National Market upon or shortly after the consummation
     of the Merger.  See "Risk Factors--No Assurance of Public Market."

          Comparative Per Share Data.  The following table sets forth certain
     comparative historical, unaudited pro forma and equivalent pro forma data
     with respect to the book value per share, net income per share and cash
     dividends per share for HSOG Common Stock and HSRC Common Stock, at the
     dates and for the periods indicated.  The "Prior to Merger" information for
     both HSOG and HSRC is historical information of the companies.  The
     "Assuming Merger" information as of December 31, 1996 and for the years
     ended December 31, 1996 and 1995 is pro forma pooled information giving
     effect to the Merger and the Stock Split presented (i) on a per share
     basis based on the shares of New HSOG Common Stock to be outstanding ("Pro
     Forma") and (ii) on the basis of the number of shares of New HSOG Common
     Stock into which each share of HSRC Common Stock will be converted,
     assuming an Exchange Ratio of 48.66 ("Per Equivalent HSRC Share").  The Pro
     Forma and Per Equivalent HSRC Share data have been included for comparative
     purposes only and do not purport to be indicative of the financial results
     had the Merger occurred on January 1, 1995.

     (1)  Assumes that HSOG will issue 2,742,203 shares of New HSOG Common Stock
          for all the outstanding shares of HSRC Common Stock (other than shares
          held by HSOG which will be eliminated in the Merger) (i.e., 48.66
          shares of New HSOG Common Stock for each such share of HSRC Common
          Stock).  For purposes of calculating per share data, the Merger is
          assumed to be effective on January 1, 1995 for purposes of income
          statement data and as of the date presented for the purposes of the
          book value data.

     (2)  Adjusted to reflect the Stock Split (30-for-1) to be effected in
          connection with the consummation of the Merger.

     (3)  Book value amounts are computed based upon the number of common shares
          outstanding (or assumed to be outstanding for information giving
          effect to the consummation of the Merger) at the end of the respective
          period presented.

     Risk Factors

          See "Risk Factors" with respect to factors which should be considered
     in evaluating the Merger.

     Amendments to the HSOG Certificate of Incorporation

          HSOG stockholders will consider and vote upon the following eight
     proposals to amend the HSOG Certificate.  If approved by HSOG stockholders,
     the proposed amendments will only become effective if the Merger is
     consummated.  See "Amendments to the Certificate of Incorporation of HSOG"
     for a more complete discussion of the proposed amendments.

          Proposed Amendment No. 1.  The HSOG Certificate currently provides
     that HSOG's corporate existence will terminate on March 12, 2007.  The
     proposed amendment to the HSOG Certificate provides that HSOG will have
     perpetual existence.

                                      -9-
<PAGE>
 
          Proposed Amendment No. 2.  The HSOG Certificate currently limits the
     scope of HSOG's business to the oil, gas and mineral business and related
     activities.  The proposed amendment to the HSOG Certificate provides that
     HSOG may engage in any lawful activities for which corporations may be
     organized under the Oklahoma General Corporation Act.

          Proposed Amendment No. 3.  The HSOG Certificate currently provides
     that the HSOG Board of Directors shall consist of seven directors.  The
     proposed amendment to the HSOG Certificate provides that the HSOG Board
     shall consist of not less than three nor more than 15 directors, the exact
     number within such limits to be determined by a majority vote of the
     directors.

          The proposed amendment could be used by the HSOG Board as a measure to
     deter or postpone an attempt to gain control of HSOG.  In addition, the
     provisions of the proposed amendment could also have the effect of
     discouraging a third party from initiating a proxy contest, making a tender
     offer or otherwise gaining control of HSOG even though such transaction
     could be beneficial to HSOG and its stockholders.  See "Amendments to the
     Certificate of Incorporation of HSOG."

          Proposed Amendment No. 4.  The HSOG Certificate currently provides
     that any merger, consolidation or sale of a substantial portion of the
     assets of HSOG, or any change in the number of directors of HSOG set forth
     in the HSOG Certificate, must be approved by the holders of at least 66 2/3
     percent of the outstanding shares of HSOG voting stock.  The proposed
     amendment would eliminate the provisions requiring the approval of the
     holders of at least 66 2/3 percent of the outstanding shares of voting
     stock of HSOG to effect any such transaction or change in number of
     directors. If the proposed amendment is approved by HSOG stockholders, any
     transaction involving a merger, consolidation or sale of a substantial part
     of the assets of HSOG, or any change to the HSOG Certificate effecting the
     number of directors, will require the affirmative vote of the holders of at
     least a majority of the outstanding shares of HSOG voting stock unless the
     Business Combination Statute of the Oklahoma General Corporation Act
     (discussed under "Description of HSOG Capital Stock--Certain Provisions and
     Arrangements That May Have an Anti-Takeover Effect") is applicable to such
     transaction.

          Proposed Amendment No. 5.  The proposed amendment to the HSOG
     Certificate would limit personal liability of HSOG directors to HSOG or its
     stockholders for monetary damages for certain acts or omissions in their
     capacities as directors as allowed under Oklahoma law.  The HSOG
     Certificate currently contains no such provision.

          Proposed Amendment No. 6.  Currently, any changes to the HSOG Bylaws
     must be approved by a vote of the stockholders of HSOG.  The proposed
     amendment to the HSOG Certificate would grant the power to the HSOG Board
     to adopt, repeal or amend the Bylaws of HSOG.  As provided by the Oklahoma
     General Corporation Act, even if the proposed amendment to the HSOG
     Certificate is approved by HSOG stockholders, HSOG stockholders will also
     retain the power to adopt, amend or repeal the Bylaws of HSOG.

          Proposed Amendment No. 7.  The HSOG Certificate is currently silent on
     the subject of indemnification of HSOG's directors, officers, employees and
     agents.  The proposed amendment to the HSOG Certificate provides that the
     HSOG Board may indemnify and advance certain expenses to a director,
     officer, employee or agent of HSOG to the maximum extent provided under the
     Oklahoma General Corporation Act.

          Proposed Amendment No. 8.  There currently exists some uncertainty
     under Oklahoma law as to the continued effectiveness of certain provisions
     of the Oklahoma Business Corporation Act with respect to Oklahoma
     corporations like HSOG which were incorporated prior to the enactment of
     the Oklahoma General Corporation Act in 1986.  The Oklahoma Business
     Corporation Act was repealed by the enactment of the Oklahoma General
     Corporation Act.  The proposed amendment would clarify that HSOG shall be
     governed solely by the provisions of the Oklahoma General Corporation Act.

     Approval of the HSOG 1997 Incentive Stock Plan

               HSOG's stockholders will consider and vote on a proposal to
     approve the HSOG 1997 Incentive Stock Plan.  The plan authorizes the grant
     of stock options and shares of restricted stock to key employees, officers,
     directors and consultants of HSOG.  A total of 451,736 shares of New HSOG
     Common Stock has initially been reserved for issuance under the plan.  The
     number of shares of New HSOG Common Stock reserved for issuance under the
     HSOG 1997 Incentive Stock Plan will increase to an amount equal to 10% of
     the outstanding shares of New HSOG Common Stock upon the issuance of any
     additional shares of such stock by HSOG subsequent to the Merger (other
     than shares issued pursuant to the HSOG 1997 Incentive Stock Plan).  See
     "Approval of the HSOG 1997 Incentive Stock Plan."

                                 RISK FACTORS


          The following factors should be considered carefully by the
     stockholders of HSOG and HSRC in connection with voting upon the Merger.

     Effects of the Merger

          Management and the Board of Directors of both HSOG and HSRC believe
     that the Merger will be in the best interests of stockholders of each
     company for the reasons discussed under "The Merger--Background of and
     Reasons for the Merger." However, there may be consequences of the Merger
     which could adversely affect all or some of the stockholders of either
     company. These consequences include the following:

          .  Reduction in Total Amount of Percentage Depletion Deductions. The
             surviving company will not be entitled to claim the same amount of
             deductions for statutory percentage depletion with respect to its
             oil and gas production after the Merger as the individual companies
             combined are currently entitled to claim. See "The Merger--
             Depletion Deductions" for a discussion of the possible consequences
             of the loss of depletion deductions in connection with the Merger.


          .  Adverse Impact of Merger on Working Capital of HSRC. On a pro forma
             basis, at June 30, 1997, assuming the consummation of the Merger,
             HSOG, as the surviving company, would have had a working capital
             deficit of approximately $137,000. At June 30, 1997, HSRC had
             positive working capital of approximately $794,000. The working
             capital deficit of the surviving company after the Merger could
             adversely affect its ability to fund its current operations and
             meet other obligations. However, management of the companies
             believes that HSOG will be able to adequately provide for its
             working capital needs out of its cash flow and available borrowings
             under its credit facilities. See "Management's Discussion and
             Analysis of Financial Condition and Results of Operations of HSOG--
             Financial Condition and Liquidity."

     Management of the companies does not believe that the foregoing
     consequences will result in any materially adverse effect on the
     stockholders of the companies by virtue of the Merger, but there can be no
     assurance that either these or other presently unforeseen consequences of
     the Merger will not have a materially adverse effect on the investments of
     the stockholders in the companies.

     Limitations of the Opinion of Financial Advisor

          In considering the opinion of Principal rendered on the fairness of
     the consideration to be received by the stockholders of HSRC from a
     financial point of view to the disinterested stockholders of HSOG and HSRC,
     stockholders of HSOG and HSRC should carefully consider the following
     limitations on the scope of such opinion:

          .  There is an inherent conflict of interest in Principal's evaluation
             of the fairness, from a financial point of view, of the
             consideration to be received in the Merger by HSRC stockholders on
             behalf of the disinterested stockholders of both HSOG and HSRC.

          .  In rendering its fairness opinion, Principal relied on the accuracy
             and completeness of certain financial and other information
             provided by HSOG and HSRC with only limited independent
             verification of the accuracy of such information. Any significant

                                      -12-
<PAGE>
 
            inaccuracies in such information could have a material effect on the
            results of the analyses performed by Principal in connection with
            its opinion and its conclusions on the fairness of the Merger. See
            "The Merger--Opinion of Financial Advisor."

          . The fairness opinion of Principal is as of August 14, 1997, and
            Principal is not obligated to update its opinion as of the date of
            this Proxy Statement/Prospectus or at any time prior to consummation
            of the Merger.

     Conflict of Interests of Special Committees to the HSOG and HSRC Boards

          Each member of the special committees of the Boards of Directors of
     HSOG and HSRC appointed to consider the Merger proposal serves as a
     director of both companies and owns shares of both HSOG Common Stock and
     HSRC Common Stock.  As a result, it could be construed that each member
     could have a conflict of interest with respect to the stockholders of one
     company when considering the fairness of the Merger to the stockholders of
     the other company.  In addition, such members could also be viewed as
     having a conflict of interest in the selection of Principal as the
     financial advisor to the Boards of both companies with respect to the
     proposed Merger. The Boards of Directors of HSOG and HSRC elected to engage
     a single financial advisor to render a fairness opinion on behalf of both
     Boards of Directors of HSOG and HSRC because of the similarities in the
     operations and assets of the companies and the increased costs which would
     be incurred by engaging two separate firms.  Had a separate firm been
     engaged to render an opinion on behalf of each company with respect to the
     Merger, it is possible that one or both of such firms could have reached
     different conclusions than that of Principal with respect to the fairness
     of the Merger from a financial point of view to the disinterested
     stockholders of such company.


     Determination of Exchange Ratio

          In determining the appropriate Exchange Ratio for use in converting
     the outstanding shares of HSRC Common Stock into New HSOG Common Stock in
     connection with the Merger, Principal, the financial advisor, attempted to
     determine a fair allocation of the post-Merger ownership of HSOG among the
     current stockholders of HSOG and HSRC.  This was done by estimating the
     approximate value of each company and the contribution of its assets and
     operations to the combined company.  Management and the Boards of each
     company believe that the Exchange Ratio has been established on a fair and
     equitable basis.  Although the assets and operations of the companies are
     very similar, HSOG has outstanding indebtedness and a working capital
     deficit while HSRC has no outstanding indebtedness and positive working
     capital.  Because of the differences in the companies, any change in the
     methodology or assumptions  used to value the respective companies for
     purposes of determining the Exchange Ratio could have had a material effect
     on the Exchange Ratio which could, in turn, have a material effect upon the
     value of the post-Merger investment in HSOG by the stockholders.  See "The
     Merger--Determination of Exchange Ratio."


     Risks Inherent in Oil and Gas Industry

          The nature and extent of the principal business and activities of HSOG
     and HSRC are not expected to significantly change as a result of the
     Merger.  Nevertheless, stockholders of each company should be aware of the
     types of risks expected to be encountered by HSOG as the surviving
     corporation in connection with its oil and gas exploration, production,
     operating and marketing activities.  The more significant of these risks
     are summarized below:

                                      -13-
<PAGE>
 
     .    Volatility of Oil and Gas Prices.  HSOG's revenues, profitability and
          future rate of growth are substantially dependent upon prevailing
          prices for natural gas, oil and condensate.  Historically, natural gas
          and oil prices and markets have been volatile, and they are likely to
          continue to be volatile in the future.  Prices for oil and natural gas
          are subject to wide fluctuations in response to market uncertainty,
          changes in supply and demand and a variety of additional factors, all
          of which are beyond HSOG's control.  These factors may include
          political conditions in oil producing regions, including the Middle
          East, the domestic and foreign supply of oil and natural gas, the
          level of consumer demand, overall economic conditions, weather
          conditions and the price and availability of alternative fuels.  A
          substantial or extended decline in oil and natural gas prices could
          have a material adverse effect on HSOG's financial position, results
          of operations, quantities of oil and gas reserves that may be
          economically produced and access to capital.  In addition, the
          marketability of HSOG's production depends upon a number of factors
          beyond HSOG's control, including the availability and capacity of
          gathering, transportation and processing facilities, the effect of
          federal and state regulation of production and transportation, general
          economic conditions, changes in supply due to drilling by other
          producers and changes in demand.  See "Description of the Business of
          The Home-Stake Companies--Marketing."

     .    Acquisition Risks.  HSOG has in the past acquired and intends to
          continue to acquire producing oil and gas properties.  Although HSOG
          performs a review of the properties it acquires that it believes is
          consistent with industry practice, such reviews are inherently
          incomplete.  Even an in-depth review of all properties and records may
          not necessarily reveal existing or potential problems, nor will it
          permit a buyer to become sufficiently familiar with the properties to
          assess fully their deficiencies, liabilities and capabilities.
          Inspections may not always be performed on every well, and potential
          environmental problems are not necessarily observable even when an
          inspection is undertaken.

     .    Risk of Oil and Gas Operations.  HSOG's operations are subject to all
          the risks typically associated with the operation and development of
          oil and gas properties and the drilling of oil and gas wells.
          Drilling activities carry the risk that no commercial production will
          be obtained.  The cost of drilling, completing and operating wells is
          often uncertain, and drilling and/or production may be curtailed,
          delayed or cancelled as a result of many factors.  HSOG's operations
          are also subject to a number of additional risks, including, but not
          limited to, uncontrollable flows of oil, natural gas, brine or well
          fluids into the environment (including groundwater contamination),
          fires, explosions, and other risks, any of which could result in
          substantial losses to HSOG.  HSOG's business is also subject to
          environmental hazards such as oil spills, gas leaks, ruptures and
          discharges of toxic gases, which could expose HSOG to substantial
          liability due to pollution and other environmental damage.  In
          accordance with customary industry practice, HSOG maintains insurance
          against some, but not all, potential risks.  There can be no assurance
          that such insurance will be adequate to cover any loss or exposure for
          liability, or that such insurance will continue to be available on
          terms acceptable to HSOG.

     .    Environmental Concerns and Government Regulation.  HSOG's business is
          subject to a variety of federal, state and local government
          regulations, including regulations concerning the prevention of waste,
          the discharge of materials into the environment, the conservation of
          natural gas and oil, pollution, permits for drilling operations,
          drilling bonds, reports concerning operations, the spacing of wells,
          the unitization and pooling of properties, the clean-up of well sites,
          and various other matters, including taxes.  Such laws and regulations
          have increased the costs of planning, designing, drilling, installing,
          operating and abandoning oil and gas wells and other facilities.
          Moreover, the laws and regulations protecting the environment have
          become more stringent in recent years and such trend is likely to
          continue.  In some circumstances such environmental laws and
          regulations may impose "strict liability," rendering a person liable
          for

                                      -14-
<PAGE>
 
          environmental damage without regard to negligence or fault on the part
          of such person.  In addition, HSOG may be exposed to liability for the
          conduct of operations or conditions caused by others or for its acts
          which were in compliance with all applicable laws at the time such
          acts were performed.  There is no assurance that laws and regulations
          enacted in the future will not adversely affect HSOG's operations.
          See "Description of the Business of The Home-Stake Companies--
          Regulation."

     .    Reliance on Estimates of Proved Reserves; Depletion of Reserves.
          There are numerous uncertainties inherent in estimating quantities of
          proved reserves and in projecting future rates of production and
          timing of development expenditures, including many factors beyond the
          control of the producer.  The reserve data set forth in this Proxy
          Statement/Prospectus represent only estimates of HSOG's and HSRC's
          engineers.  Oil and gas reserve engineering is a subjective process of
          estimating underground accumulations of oil and gas that cannot be
          measured in an exact way, and estimates by other engineers might
          differ from those included herein.  The accuracy of any reserve
          estimate is a function of the quality of available data and of
          engineering and geological interpretation and judgment.  The estimates
          of future net revenues from proved reserves of HSOG and HSRC are based
          upon various assumptions, including those prescribed by the Securities
          and Exchange Commission.  Actual future production, oil and gas
          prices, revenues, taxes, capital expenditures and operating expenses
          may vary substantially from those assumed in making the estimates, and
          HSOG's and HSRC's reserves may be subject to upward or downward
          revision.

          HSOG's future performance is dependent upon its ability to find or
          acquire additional oil and gas reserves that are economically
          recoverable.  Unless HSOG successfully replaces the reserves that it
          produces, HSOG's reserves will decline, resulting eventually in a
          decrease in oil and gas production and lower revenues and cash flow
          from operations.

     .    Business Risks.  HSOG must continually acquire and explore for and
          develop new oil and gas reserves to replace those being depleted by
          production.  Without the successful acquisition or drilling of
          reserves, HSOG's assets, properties and revenues will decline.  Oil
          and gas exploration and development activities are subject to numerous
          risks, including the risk that no commercially productive oil or gas
          reservoirs will be encountered.  The cost of drilling, completing and
          operating wells may exceed initial estimates.  HSOG's operations may
          be curtailed, delayed or cancelled as a result of the lack of adequate
          capital resources and other factors, some of which are not within
          HSOG's control, such as title problems, weather conditions, compliance
          with governmental requirements, mechanical difficulties and shortages
          or delays in the delivery of equipment.  New gas wells may be shut-in
          for lack of a market until a gas pipeline or gathering system with
          available capacity is extended into the area.  In addition, HSOG's
          properties may be susceptible to hydrocarbon drainage from production
          by other operators on adjacent properties.

     .    Competition.  HSOG operates in a highly competitive environment.  In
          seeking to acquire desirable oil and gas properties and in marketing
          its oil and gas production, HSOG faces intense competition from both
          major and independent oil and gas companies, as well as from numerous
          individuals and marketers.  Many of these competitors have financial
          and other resources substantially in excess of those available to
          HSOG.  See "Description of the Business of The Home-Stake Companies--
          Competition."

     No Assurance of Public Market

          HSOG Common Stock has historically traded only sporadically and there
     has been no public trading market for such shares.  Although HSOG currently
     intends to apply for listing of the New HSOG

                                      -15-
<PAGE>
 
     Common Stock on the Nasdaq National Market, there can be no assurance that
     such inclusion will occur or that an adequate trading market for New HSOG
     Common Stock will develop or be sustained after such inclusion.  On March
     3, 1997, Nasdaq filed proposed new listing standards with the Commission
     for initial listing which must be satisfied by companies applying for
     listing on the Nasdaq National Market after such date.  HSOG, as the
     surviving corporation after the Merger, must meet the Nasdaq National
     Market listing criteria, including:  (i) net tangible assets of at least $6
     million; (ii) pretax income in the latest fiscal year, or in two of the
     last three fiscal years, of at least $1,000,000; (iii) at least 400 public
     holders of New HSOG Common Stock; (iv) at least 1,100,000 publicly held
     shares of New HSOG Common Stock; (v) a market value of publicly held shares
     of at least $8 million; (vi) a minimum bid price of $5 per share; and
     (vii) three registered and active market makers for its securities.
     Furthermore, HSOG will be required to meet certain standards for continued
     listing on the Nasdaq National Market. There is no assurance that HSOG will
     meet these continued listing requirements in the future. If New HSOG Common
     Stock fails to be maintained on the Nasdaq National Market, such failure
     would have an adverse effect on the liquidity of the New HSOG Common Stock
     and, as a result, on the market price thereof.

     Possible Effect of Authorized Shares of HSOG Capital Stock

          Upon consummation of the Merger, there will be approximately 7,500,000
     shares of authorized but unissued shares of New HSOG Common Stock and
     2,000,000 shares of Preferred Stock having such designations, rights and
     preferences as may be determined from time to time by the Board of
     Directors of HSOG.  The Board of Directors is empowered to issue Preferred
     Stock, without stockholder approval, with dividend, liquidation,
     conversion, voting or other rights that could adversely affect the voting
     power or other rights of the holders of New HSOG Common Stock.  The
     Preferred Stock could be utilized, under certain circumstances, as a method
     of discouraging, delaying or preventing a change in control of HSOG.  The
     shares of authorized but unissued New HSOG Common Stock and Preferred Stock
     might also be considered as having the effect of discouraging an attempt by
     another person, through the acquisition of a substantial number of
     outstanding shares of New HSOG Common Stock or Preferred Stock, to acquire
     control of HSOG with a view of imposing a merger, sale of all or any part
     of HSOG's assets or a similar transaction, since the issuance of additional
     shares could be used to dilute the stock ownership and voting power held by
     such person.  Any transaction which may be so discouraged or avoided could
     be a transaction that HSOG's stockholders might consider to be in their
     best interests, although it should be noted that the Board of Directors of
     HSOG has a fiduciary duty to act in the best interests of HSOG's
     stockholders.  See "Description of HSOG Capital Stock--Certain Provisions
     and Arrangements That May Have an Anti-Takeover Effect."

          The authorized but unissued shares of New HSOG Common Stock and
     Preferred Stock would be available for issuance by the Board of Directors
     without further stockholder approval (subject to Oklahoma law) to take
     advantage of future opportunities for the issuance of common stock or
     preferred stock to improve HSOG's capital structure, in connection with
     possible acquisitions, in connection with employee benefit plans and for
     other corporate purposes.  See "Description of HSOG Capital Stock--HSOG
     Common Stock and New HSOG Common Stock" and "--HSOG Preferred Stock."

     Forward-Looking Statements

          There are a number of statements in this Proxy Statement/Prospectus
     which address activities, events or developments which HSOG expects or
     anticipates will or may occur in the future, including such things as
     future capital expenditures (including the amount and nature thereof),
     wells to be drilled, the effects of natural gas and oil regulation,
     acquisitions of assets, production of natural gas and oil reserves,
     expansion and growth of HSOG's businesses and operations and other such
     matters.  These statements are based on certain assumptions and analyses
     made by HSOG in light of its experience and its perception of historical
     trends, current conditions and expected future developments as well as
     other

                                      -16-
<PAGE>
 
     factors it believes are appropriate under the circumstances.  However,
     whether actual results and developments will conform with HSOG's
     expectations and predictions is subject to a number of risks and
     uncertainties, including the risk factors discussed in this section;
     general economic, market or business conditions; the business opportunities
     (or lack thereof) that may be presented to and pursued by  HSOG; changes in
     laws or regulations and other factors, most of which are beyond the control
     of HSOG.  Consequently, all of the forward-looking statements made in this
     Proxy Statement/Prospectus are qualified by these cautionary statements and
     there can be no assurance that the actual results or developments
     anticipated by HSOG will be realized or, even if substantially realized,
     that they will have the expected consequences to or effects on HSOG or its
     business or operations.  HSOG does not undertake to update, revise or
     correct forward looking statements.

          HSOG Special Meeting.  At the HSOG Meeting, holders of HSOG Common
     Stock will consider and vote upon the following proposals:

               (1) To approve and adopt the Merger Agreement between HSOG and
          HSRC, pursuant to which, among other things, (a) HSRC will be merged
          with and into HSOG with HSOG to be the surviving corporation in the
          Merger, (b) the Common Stock of HSOG will be split on a 30-for-1

          of New HSOG Common Stock for each share of HSRC Common Stock owned as
          of the effective time of the Merger, and (d) each stockholder of HSOG
          (other than HSRC and stockholders who have exercised their appraisal
          rights) will receive 30 shares of New HSOG Common Stock for each share
          of HSOG Common Stock owned as of the effective time of the Merger.  In
          addition, the terms of the Merger Agreement also provide for the
          amendment of HSOG's certificate of incorporation to increase the
          authorized capital stock of HSOG in order to effect the Merger and the
          Stock Split.

               (2) To approve eight proposed amendments to the HSOG Certificate

          HSRC Special Meeting.  At the HSRC Meeting, holders of HSRC Common
     Stock will consider and vote upon the proposal to approve and adopt the
     Merger Agreement between HSOG and HSRC, pursuant to which, among other
     things, (a) HSRC will be merged with and into HSOG with HSOG to be the
     surviving corporation in the Merger, (b) the Common Stock of HSOG will be
     split on a 30-for-1 basis, (c) each stockholder of HSRC (other than HSOG
     and stockholders who have exercised their appraisal rights) will receive
     48.66 shares of New HSOG Common Stock for each share of HSRC Common Stock
     owned as of the effective time of the Merger, and (d) each stockholder of
     HSOG (other than HSRC and stockholders who have exercised their appraisal
     rights) will receive 30 shares of New HSOG Common Stock for each share of
     HSOG Common Stock owned as of the effective time of the Merger.

     HSRC stockholders will also transact any other business as may properly be
     brought before the HSRC Meeting or any adjournment or postponement thereof.

          Each of the Boards of Directors of HSOG and HSRC unanimously approved
     the Merger Agreement and recommends that its stockholders vote FOR the
     approval and adoption of the Merger Agreement and the Merger.  See "The
     Merger--Background of and Reasons for the Merger."  The Board of Directors
     of HSOG further recommends that its stockholders approve all of the
     amendments to the HSOG Certificate.

     HSRC at 15 East 5th Street, Suite 2800, Tulsa, Oklahoma at 9:00 a.m., Tulsa
     time, on November 20, 1997, or at any adjournment or postponement thereof,
     for the purposes set forth herein and in the accompanying Notice of Special
     Meeting of Stockholders being delivered to HSRC Stockholders.

     Votes Required

          The affirmative vote of the holders of 66 2/3 percent of the
     outstanding shares of HSOG Common Stock is required for the approval and
     adoption of the Merger Agreement. The affirmative vote of the holders of a
     majority of the outstanding shares of HSOG Common Stock is required for the
     approval and adoption of Proposed Amendments Nos. 1, 2 and 5 through 8 to
     the HSOG Certificate of Incorporation and the affirmative vote of the
     holders of 66 2/3 percent of the outstanding shares of HSOG Common Stock is
     required for the approval and adoption of Proposed Amendments Nos. 3 and 4
     to the HSOG Certificate of Incorporation. See "Amendments to the HSOG
     Certificate of Incorporation." In addition, the holders of a majority of
     the shares of HSOG Common Stock present or represented by proxy at the HSOG
     Meeting is required to approve the HSOG 1997 Incentive Stock Plan. HSRC,
     which owns approximately 33.9 percent of the outstanding shares of HSOG
     Common Stock, intends to vote all such shares of Common Stock in favor of
     approval of the Merger Agreement and the amendments to the HSOG
     Certificate. As of July 31, 1997, directors and executive officers of HSOG
     and their affiliates beneficially owned approximately 11.5 percent of the
     outstanding shares of HSOG Common Stock. The directors and executive
     officers of HSOG have indicated that they intend to vote their shares of
     HSOG Common Stock in favor of approval of the Merger Agreement and the
     amendments to the HSOG Certificate.

          The affirmative vote of the holders of 66 2/3 percent of the
     outstanding shares of HSRC Common Stock is required for the approval and
     adoption of the Merger Agreement. HSOG, which owns approximately 19.3
     percent of the outstanding shares of HSRC Common Stock, intends to vote all
     such shares of Common Stock in favor of approval of the Merger Agreement.
     As of July 31, 1997, directors and executive officers of HSRC and their
     affiliates beneficially owned approximately 20.7 percent of the outstanding
     shares of HSRC Common Stock. The directors and executive officers of HSRC
     have indicated that they intend to vote their shares of HSRC Common Stock
     in favor of approval of the Merger Agreement.

     Voting of Proxies

          Shares of HSOG Common Stock or HSRC Common Stock, as the case may be,
     represented by properly executed proxies received at or prior to the HSOG
     and HSRC Meetings, will be voted at the appropriate Meeting in the manner
     specified by the holders of such shares.  Properly executed proxies which
     do not contain voting instructions will be voted FOR approval and adoption
     of the Merger Agreement and, with respect to HSOG stockholders only, FOR
     approval of the amendments to the HSOG Certificate and approval of the HSOG
     1997 Incentive Stock Plan.  Abstentions from voting and broker non-votes
     will be counted for purposes of determining the presence or absence of a
     quorum for the transaction of business at the HSOG Meeting and HSRC
     Meeting.  Abstentions from voting will be included in the determination of
     whether the required number of affirmative votes are received on each of
     the proposals submitted to the stockholders for a vote and, therefore, will
     have the same effect as a vote against the proposal. Broker non-votes as to
     a particular proposal will not be considered as present and entitled to
     vote with respect to such proposal. As a result, a broker non-vote will
     have no effect on the approval of the HSOG 1997 Incentive Stock Plan, but
     will have the same effect as a vote against the Merger and against the
     amendments to the HSOG Certificate.

          If any other matters are properly presented at either the HSOG Meeting
     or the HSRC Meeting for consideration, the person or persons named in the
     relevant form of proxy enclosed herewith and acting thereunder will have
     discretion to vote on such matters in accordance with their best judgment,
     unless the proxy indicates otherwise.  Neither HSOG nor HSRC has any
     knowledge of any matters to be presented at the HSOG Meeting or the HSRC
     Meeting, as the case may be, other than those matters referred to and
     described herein.

Revocability of Proxies

     The grant of a proxy on the enclosed HSOG or HSRC form of proxy does not
preclude a stockholder from voting in person or otherwise revoking a proxy.
Attendance at the relevant meeting will not in and of itself constitute
revocation of a proxy. A stockholder may revoke a proxy at any time prior to its
exercise by delivering to Chris K. Corcoran, Executive Vice President, Chief
Financial Officer and Secretary of HSOG and HSRC, 15 East 5th Street, Suite
2800, Tulsa, Oklahoma 74103, a duly executed revocation or a proxy bearing a
later date or by voting in person at the appropriate meeting.

Record Date; Shares Entitled to Vote; Quorum

     Only holders of record of HSOG Common Stock at the close of business on
September 30, 1997, will be entitled to receive notice of and to vote at the
HSOG Meeting. At July 31, 1997, HSOG had outstanding 89,509 shares of HSOG
Common Stock. Each share of HSOG Common Stock is entitled to one vote on each
matter on which the respective holders of such shares are entitled to vote. The
presence in person or by proxy of the holders of a majority of the outstanding
shares of HSOG Common Stock will constitute a quorum for the HSOG Meeting.

     Only holders of record of HSRC Common Stock at the close of business on
September 30, 1997, will be entitled to receive notice of and to vote at the
HSRC Meeting. At July 31, 1997, HSRC had outstanding 69,808 shares of HSRC
Common Stock. Each share of HSRC Common Stock is entitled to one vote on each
matter on which the respective holders of such shares are entitled to vote. The
presence in person or by proxy of the holders of a majority of the outstanding
shares of HSRC Common Stock will constitute a quorum for the HSRC Meeting.

Solicitation of Proxies

     Each of HSOG and HSRC will bear the cost of the solicitation of proxies
from its own stockholders, except that HSOG and HSRC will share equally the cost
of printing and mailing this Proxy Statement/Prospectus. In addition to
solicitation by mail, the directors, officers and employees of each company may
solicit proxies from stockholders of such company by telephone or telegram or in
person. Such persons will not be additionally compensated, but will be
reimbursed for reasonable out-of-pocket expenses incurred in connection with
such solicitation. Arrangements will also be made with brokerage firms,
nominees, fiduciaries and other custodians, for the forwarding of solicitation
materials to the beneficial owners of shares held of record by such persons, and
HSOG and HSRC will reimburse such persons for their reasonable out-of-pocket
expenses in connection therewith.

Submission of Proposals for 1998 Annual Meeting

     Any stockholder proposal to be presented at the 1998 Annual Meeting of
Stockholders of HSOG should be directed to The Home-Stake Oil & Gas Company, 15
E. 5th Street, Suite 2800, Tulsa, Oklahoma 74103, Attention: Chris K. Corcoran,
Corporate Secretary, and must be received by HSOG on or before December 18,
1997. All such proposals must comply with Rule 14a-8 promulgated by the

HSRC stockholder desiring to submit a proposal to be considered at the 1998
Annual Meeting of Stockholders of HSRC should direct such proposal to The Home-
Stake Royalty Corporation, 15 E. 5th Street, Suite 2800, Tulsa, Oklahoma 74103,
Attention: Chris K. Corcoran, Corporate Secretary, and such proposal must be

                                   THE MERGER

     General

          The Merger Agreement provides for a business combination between HSOG
     and HSRC in which HSRC will be merged with and into HSOG and the holders of
     HSRC Common Stock will be issued shares of New HSOG Common Stock, in a
     transaction treated in a manner similar to a pooling of interests for
     accounting purposes and as a reorganization for federal income tax
     purposes.  The discussion in this Proxy Statement/Prospectus of the Merger
     and the description of the Merger's principal terms are subject to and
     qualified in their entirety by reference to the Merger Agreement, a copy of
     which is attached to this Proxy Statement/Prospectus as Appendix A and
     which is incorporated herein by reference.

     Background of and Reasons for the Merger

          Background.  Over the past 40 years, HSOG and HSRC have been operated
     as essentially a single company.  See "Description of Businesses of The
     Home-Stake Companies--General."  For most of this period, the companies
     have split administrative costs evenly and have generally participated
     jointly in acquisition and exploration activities on an equal basis;
     however, as discussed below, the differences in the financial condition and
     liquidity of the two companies resulted in a change in the participation
     arrangement between the companies effective January 1, 1996, whereby HSRC's
     participation interest in new drilling ventures, acquisitions and other
     investments is 60% and HSOG's participation interest therein is 40%.  The
     companies share the same employees and the same persons comprise the Board
     of Directors of each company.  There are approximately 200 record holders
     of HSOG Common Stock and approximately 300 record holders of HSRC Common
     Stock, with approximately 90 persons owning shares in both companies.

          The Boards of Directors of HSOG and HSRC have considered a merger of
     the companies a number of times over the past years, beginning in 1969.  In
     1969, and again in each of 1984, 1989 and 1991, the Boards concluded that
     the costs of the transaction would outweigh the potential benefits that
     would be received.  Of particular concern in each case was the effect of
     the loss of statutory depletion deductions for federal income tax purposes.
     Currently, each company is able to claim statutory depletion deductions
     with respect to its crude oil production of up to 1,000 barrels per day (or
     up to an aggregate of 2,000 barrels per day for both companies combined).
     A merger would result in the combined company being able to claim such
     deductions with respect to only 1,000 barrels per day.  See "The Merger--
     Depletion Deductions."

          In late 1994, the Boards of Directors of HSOG and HSRC again
     considered the advisability of a merger of the companies.  Based primarily
     on the same reasons that the Boards of HSOG and HSRC are currently
     proposing the approval of the Merger (see "-- Reasons for the Merger"
     below), in early 1995 the Boards approved a proposed merger of HSRC with
     and into HSOG pursuant to which HSRC stockholders would receive, in effect,
     1.65 shares of HSOG Common Stock for each share of HSRC Common Stock they
     held.  The merger proposal was presented to and approved by the
     stockholders of each company; however, stockholders holding approximately
     20% and 15% of the outstanding shares of HSOG Common Stock and HSRC Common
     Stock, respectively, exercised their dissenters' appraisal rights with
     respect to the merger proposal.  The percentage of dissenting shares
     exceeded one of the conditions to the proposed merger and the Boards of
     Directors of the companies decided not to waive this condition because each
     company would have had to incur a substantial amount of additional
     indebtedness to purchase the shares of those stockholders perfecting their
     dissenters' appraisal rights.  At such time, each company had recently
     financed a significant acquisition of oil and gas properties and it was
     believed that incurring the additional indebtedness required to effect the
     purchase of the dissenting stockholders' shares was not in the best
     interests of the companies as it could limit each company's ability to
     participate in future acquisitions or other business opportunities.
     Accordingly, the proposed Merger was never consummated.

          For the reasons discussed below, in May 1997, the Boards of Directors
     of HSOG and HSRC decided to again consider the advisability of merging the
     companies.  At a joint meeting held May 19, 1997, officers of the companies
     were instructed to solicit bids from potential financial advisors.
     Subsequently, at a joint 

                                      -21-
<PAGE>
 
     meeting held on June 23, 1997, each of the Boards appointed a special
     committee of its members to consider and report to the Board regarding the
     Merger proposal. The special committee appointed by the HSOG Board is
     comprised of Messrs. Simpson, McCain and Grindstaff, while the HSRC special
     committee is comprised of Messrs. Allegood, Gutman and Morris. At this
     joint meeting, the special committees agreed that Principal would be
     engaged as a financial advisor to review the Merger proposal, assist in
     developing the Exchange Ratio and report on the fairness of the Merger to
     the stockholders of both companies.

          Principal presented its report to the special committees on August 14,
     1997, and met with each of the committees.  See "--Opinion of Financial
     Advisor" below.  The Boards then met jointly after such presentation, at
     which time each committee recommended to its Board that the Merger be
     approved on the terms proposed.  The report and fairness opinion of
     Principal was also presented to the Boards at that meeting.  Based on the
     recommendations of their respective special committees and the opinion of
     Principal, the Boards unanimously approved the Merger proposal and directed
     that the proposal be presented to their respective stockholders at the
     Special Meetings of HSOG and HSRC with the recommendation that they vote
     FOR the proposal.

          Reasons for the Merger

          Notwithstanding HSOG's and HSRC's joint operations, HSOG has
     historically had higher outstanding indebtedness and debt to equity ratio
     than HSRC.  The greater resultant cash flow experienced by HSRC generally
     has created an increasing imbalance between the respective debt to equity
     ratios of the companies, often making it more difficult for HSOG to fund
     its share of new drilling ventures and property acquisitions.  As a result
     of the imbalance in the financial conditions of the companies, effective
     January 1, 1996, HSOG's participation interest in joint activities with
     HSRC was reduced by the Boards of Directors of the companies from 50% to
     40%.  As the companies attempt to increase their business activity in the
     near future, management of the companies expects that HSOG's difficulties
     in "keeping up" with HSRC could force the Boards to further change the
     participation arrangement regarding the joint activities of the companies
     in order not to hold HSRC back from the opportunities that are expected to
     be presented to it in the future.  The Boards of Directors of the companies
     believe that the Merger would alleviate this awkward situation because a
     single entity would allow management to be substantially more focused on
     the types and magnitudes of the prospects that are considered, since each
     prospect would no longer have to be reviewed from the perspective of two
     separate and somewhat different companies from the standpoint of their
     respective financial conditions and capabilities.

          As the oil and gas industry continues its consolidation, management of
     HSOG and HSRC expects that its experience and the history and tradition of
     the companies will result in an increasing number and variety of potential
     acquisition and operational opportunities.  In order to take maximum
     advantage of these opportunities, the companies will probably require
     increased financing capabilities.  Management believes that by combining
     the assets and operations of the companies and effecting an increased
     public float of its equity securities, the surviving company will have
     greater access to the capital markets, thus improving its prospects of
     obtaining the financing it may desire or require to carry out its business
     plan to the fullest extent possible.

          The common stock of each of the companies has been registered under
     the Exchange Act, and, as a consequence, the companies are required to
     submit periodic reports to the Securities and Exchange Commission and
     otherwise operate within the requirements and restrictions that are
     applicable to "public" companies.  Nevertheless, due to the relatively low
     number of stockholders and, in particular, low number of outstanding shares
     of each company, there has been no established public trading market and
     very little trading in the common stock of either company.  Management of
     the companies has received numerous inquiries in recent years from
     stockholders regarding the prospects of increasing the liquidity of the
     stock.  It is believed by the Boards that the increased stockholder base
     and number of outstanding shares that will result from the Merger, as well
     as the expected trading of the stock on the Nasdaq National Market, will
     result in a significant increase in the liquidity of the stock, although
     there can be no assurance that there will be sufficient public float or
     trading activity to ensure that the market value of the stock will be
     comparable to the values of the stock of other publicly traded oil and gas
     companies which are comparable to the surviving company from the standpoint
     of assets base and/or cash flow.

                                      -22-
<PAGE>
 
          In addition to the foregoing reasons for the Merger, the Boards and
     the special committees also took into account the transactional costs of
     the Merger and the ongoing costs, specifically the decrease in the total
     amount of the statutory depletion allowance deductions the surviving
     company will be able to claim for federal income tax purposes compared to
     the total amount claimed by the companies previously.  See "The Merger--
     Depletion Deductions."  Each of the Boards has determined that even
     considering these immediate and ongoing costs, the potential benefits of
     the Merger outweigh those costs and the Merger is in the best interests of
     the stockholders of both companies.  The Merger proposal was approved
     unanimously by the Board of each company and each Board recommends that its
     stockholders vote in favor of the Merger.

     Determination of Exchange Ratio

          The assets of HSOG and HSRC consist primarily of working interests in
     producing oil and gas leases, although each company does own mineral or
     royalty interests, certain of which are producing and others of which are
     undeveloped.  In addition, each company owns a portion of the outstanding
     stock of the other company.  The principal difference between the companies
     is that the HSOG has outstanding indebtedness, while HSRC is debt free.
     The objective in determining the Exchange Ratio was to assure the
     stockholders of each company received a fair percentage of the outstanding
     shares of the surviving company after the Merger is consummated.

          The Exchange Ratio was based upon a recommendation by Principal of a
     fair ratio of the relative values of the companies and presented to the
     special committee of each Board.  The Exchange Ratio was then calculated
     utilizing Principal's relative value recommendation and accounting for the
     cancellation of cross-owned shares.  The Exchange Ratio was then approved
     and adopted by the Board of Directors of each Company upon recommendation
     of the respective special committee.  For purposes of establishing the
     Exchange Ratio in order to determine the proportional ownership of HSOG
     upon consummation of the Merger by the respective stockholders of HSOG and
     HSRC, an estimated value for each company was calculated utilizing
     consistent procedures which took into consideration the assets and
     liabilities of each company, as well as the value of the cross-owned shares
     of common stock held by each company in the other company.  A primary
     factor utilized to value the companies was the relative estimated values of
     each company's oil and gas reserves.  The estimated values of the oil and
     gas reserves were based on an analysis of the future cash flows to be
     generated from those reserves and of recent acquisitions of oil and gas
     reserves.  The estimated value of the oil and gas reserves of the companies
     was then determined based upon consideration of all relevant factors
     applied consistently to each company.

          After establishing a value for each company's oil and gas reserves,
     the following additional adjustments were made for purposes of establishing
     the relative estimated values of each company:

               (a) the estimated value for each company was adjusted by its
          respective working capital balances and reduced for any outstanding
          long-term debt as of June 30, 1997; and

               (b) the estimated value for each company was increased by the
          estimated value of each company's respective ownership interests in
          certain non-producing mineral interests as of June 30, 1997, based on
          an appraisal (discussed below) prepared on behalf of the Boards of
          Directors of both companies.

          After the preceding adjustments were made, further adjustments were
     made to the estimated values to reflect the cross-ownership of common stock
     of each company by the other company.  The estimated value of each company
     was increased by such company's ownership percentage of the other company
     and then reduced by the other company's ownership percentage of the subject
     company.  Since the adjustments are inter-dependent, the calculation was
     repeated numerous times to arrive at a static value for the adjustment.

          Based on the valuation analysis of the companies as indicated above,
     it was determined that ownership of HSOG upon consummation of the Merger
     should be allocated approximately 60.7% to the stockholders of HSRC and
     approximately 39.3% to the stockholders of HSOG.  This allocation resulted
     in an 

                                      -23-
<PAGE>
 
     Exchange Ratio of 1.622 shares of HSOG Common Stock (or 48.66 shares of New
     HSOG Common Stock after the effect of the 30-for-1 stock split) for each
     share of HSRC Common Stock.

          In July 1997, the Boards of Directors of both companies engaged Harry
     Tucei, a certified petroleum geologist and former officer of the companies,
     to perform an appraisal of each company's non-producing mineral interests.
     Mr. Tucei had previously performed such appraisals from time to time during
     his employment with the companies from 1956 through 1993 and as a special
     consultant in 1994.  No limitations were placed on the scope of Mr. Tucei's
     appraisal.  Mr. Tucei appraised the mineral interests of both companies by
     multiplying an estimated lease bonus value per acre times the number of
     non-producing acres in which each company owned a mineral interest.  In
     determining the estimated lease bonus values utilized in the appraisal, Mr.
     Tucei reviewed and analyzed (i) the lease bonuses per acre which had
     recently been paid in the localities of the companies' mineral interests;
     (ii) the geological basins underlying the companies' mineral acreage
     (including the depths and productiveness of such geologic formations); and
     (iii) the amount of leasing and drilling activity (including the results of
     such drilling activity) in the areas surrounding the mineral acreage.
     Based on his review and analysis of the above factors, Mr. Tucei then
     utilized his professional judgment to determine an estimated lease bonus
     per acre on a state-by-state basis.  In the determination of the estimated
     lease bonus values utilized in the appraisal, Mr. Tucei necessarily made
     qualitative judgments as to the significance and relevance of each of the
     above factors and analysis performed.  Pursuant to Mr. Tucei's appraisal,
     HSOG's non-producing mineral interests were appraised at approximately
     $1,786,800 as of June 30, 1997, and HSRC's nonproducing mineral interests
     were appraised at approximately $2,379,700 as of June 30, 1997.  Mr. Tucei
     received a consulting fee of approximately $2,500 for his services.  Mr.
     Tucei owns 70 shares of HSOG Common Stock and 112 shares of HSRC Common
     Stock.  The appraised values were utilized solely for the purpose of
     estimating the relative values of the companies with respect to each other
     in the determination of the Exchange Ratio.

     Opinion of Financial Advisor

          On August 14, 1997, Principal delivered orally and in writing its
     opinion that, as of such date, the consideration to be received in the
     Merger by the stockholders of HSRC was fair to the disinterested
     stockholders of HSRC and HSOG from a financial point of view.  For purposes
     of the opinion, the term "disinterested stockholders" means holders of each
     of HSRC's and HSOG's one class of publicly traded common stock other than
     (1) directors, officers and employees of HSRC and HSOG and (2) any holder
     of 15% or more of the outstanding shares of common stock of either HSRC and
     HSOG. The full text of Principal's written opinion, which contains a
     description of the assumptions made, the matters considered by Principal
     and the limits of its review, is attached to this Proxy
     Statement/Prospectus as Appendix B. Stockholders of HSRC and HSOG are urged
     to read the opinion carefully in its entirety, especially with regard to
     the assumptions made and matters considered by Principal. Principal is
     representing both HSRC and HSOG in the Merger. The following is a summary
     of selected analyses performed by Principal (the "Principal Report") in
     connection with its opinion.

          In connection with its opinion, Principal, among other things, (i)
     analyzed certain publicly available financial statements and reports
     regarding HSRC and HSOG; (ii) analyzed certain internal financial
     statements and other financial and operating data (including 1997 and 1998
     financial budgets) concerning HSRC and HSOG prepared by management; (iii)
     reviewed certain reserve information provided by HSRC and HSOG relating to
     their respective oil and gas properties; (iv) reviewed the trading activity
     and the prices for sales for which information was available with respect
     to a limited number of trades of the common stock of HSRC and HSOG; (v)
     compared the historical and projected financial performance of HSRC and
     HSOG; (vi) reviewed the financial terms, to the extent publicly available,
     of certain comparable oil and gas transactions; (vii) reviewed the draft of
     the Merger Agreement and related documents; (viii) discussed with
     management of HSRC and HSOG the operations of and future business prospects
     for HSOG after the Merger and the anticipated financial consequences of the
     Merger to HSRC and HSOG; and (ix) performed such other analyses and
     provided such other services as it deemed appropriate.

                                      -24-

          Principal relied on the accuracy and completeness of the information
     and financial data provided to it by HSRC and HSOG, and its opinion is
     based upon such information.  Principal inquired into the reliability of
     such information and financial data only to the limited extent necessary to
     provide a reasonable basis for its opinion, recognizing that it rendered
     only an informed opinion and not an appraisal or certification of value.
     With respect to the financial budgets and reserve information prepared by
     management of HSRC and HSOG, Principal assumed that they have been
     reasonably prepared on bases reflecting the best currently available
     estimates and judgments of the future financial operations of HSRC and
     HSOG.  Because Principal relied on the accuracy and completeness of the
     information and financial data provided by HSRC and HSOG with only limited
     independent verification thereof in rendering its opinion, any significant
     inaccuracies in the information or data provided could have a material
     effect on the results of the analyses performed by Principal in connection
     with its opinion and the conclusions thereof.

          In connection with its opinion, Principal arrived at relative values
     for HSRC and HSOG using three methodologies:  a comparable reserve
     acquisitions analysis, a discounted cash flow analysis and a relative
     contribution analysis.  These methodologies are discussed below.

          Comparable Reserve Acquisitions Analysis.  In calculating the relative
     values of The Home-Stake Companies' oil and gas reserves, Principal
     examined comparable oil and gas reserve acquisition transactions that
     occurred during 1994, 1995, 1996 and the first quarter of 1997 in the mid-
     continent, on-shore Gulf Coast and Rocky Mountain regions of the United
     States as reported by John S. Herold, Inc., an independent petroleum
     research company that tracks such data.  There were 147 such transactions
     that occurred during the aforementioned periods with a mean purchase price
     of $4.78 per barrel of oil equivalent reserves.  Principal then
     specifically examined the transactions that occurred during 1996 and the
     first quarter of 1997.  There were 64 transactions during such period with
     a mean purchase price of $4.85 per barrel of oil equivalent.  Principal
     applied a multiple of $4.85 per barrel of oil equivalent to the companies'
     proved reserves which were provided to Principal by the companies.
     Principal then adjusted the resulting values to account for certain assets
     and liabilities of the companies that were not included as part of such
     analysis and then adjusted the resulting values for cross-ownership between
     the companies.

          Discounted Cash Flow Analysis.  Principal performed a discounted cash
     flow ("DCF") analysis utilizing the present value of the future cash flows
     of The Home-Stake Companies' proved reserves as of June 30, 1997, based on
     reserve reports provided to Principal by management.  In addition,
     representatives of Principal met with management to discuss the companies'
     current and projected operations.  In developing its DCF analysis,
     Principal took the pre-tax cash flow (defined as pre-tax income plus non-
     cash expenses less required capital expenditures) that the companies were
     expected to generate throughout the life of the reserves (as presented to
     Principal in the reserve reports provided by management) and discounted the
     cash flows to a present value using a 10% discount rate.  Principal then
     adjusted the resulting values to account for certain assets and liabilities
     of the companies that were not included as part of such analysis and then
     adjusted the resulting values for cross-ownership between the companies.

          Relative Contribution Analysis.  Principal and management projected
     1998 financial results for HSOG and HSRC utilizing engineering reports and
     certain assumptions provided by management.  Principal then compared the
     projected results of the two companies and adjusted for cross-ownership
     between the companies.  Principal then examined the relative contribution
     of the projected revenues, operating cash flow, net income and after tax
     cash flow of each company.

          The summary of the Principal Report set forth above does not purport
     to be a complete description of the main elements of Principal's
     presentation to the Special Committee of the Board of Directors of HSRC or
     to the Special Committee of the Board of Directors of HSOG on August 14,
     1997.  Nor does it purport to be a complete description of the analysis
     performed, or the matters considered, by in rendering its opinion dated
     August 14, 1997.  Principal believes that its analyses must be considered
     as a whole and that selecting portions of such analyses, without
     considering all analyses, would create an incomplete view of the processes
     underlying the analyses set forth in the Principal Report and its fairness
     opinion.  The fact that any specific 

                                      -25-
<PAGE>
 
     analysis has been referred to in the summary above is not meant to indicate
     that such analysis was given greater weight than any other analysis.

          In rendering its fairness opinion, Principal applied its judgment to a
     variety of complex analyses and assumptions.  Principal may have given
     various analyses more or less weight than other analyses, and may have
     deemed various assumptions more or less probable than other assumptions.
     The assumptions made, and the judgments applied, by Principal in rendering
     its opinion are not readily susceptible to description beyond that set
     forth in the written text of the fairness opinion itself.

          In developing its view of the consideration to be received in the
     Merger, Principal assumed that, because of common practices used in the oil
     and gas industry to evaluate assets, the methodologies described above
     provided a reasonable and consistent basis for determining the relative
     values for HSRC and HSOG.

          The engagement letters between each of HSRC and HSOG and Principal
     provide that Principal is to receive a fee in the amount of $37,500 from
     each company (an aggregate of $75,000), 50% of which was paid upon
     execution of the letter and the remaining 50% of which was paid upon
     delivery of the written fairness opinion.  HSRC and HSOG also have agreed
     to reimburse Principal for its reasonable out-of-pocket expenses, including
     fees and expenses of counsel, and to indemnify Principal and its affiliates
     against certain claims, losses, liabilities and expenses in connection with
     its services as financial advisor, including those arising under the
     federal securities laws.

          Principal, an investment banking firm headquartered in Dallas, Texas,
     engages in, among other things, the valuation of businesses and their
     securities in connection with mergers and acquisitions, leveraged buy-outs,
     negotiated underwritings, private placements of debt and equity and for
     corporate and estate purposes. The predecessor of Principal has acted as an
     investment advisor to the Board of Directors of each of HSOG and HSRC with
     respect to an unsolicited tender offer for the companies' outstanding
     securities in 1993.

     Conduct of the Business of HSOG After the Merger

          It is anticipated that after the Merger, HSOG will conduct its
     business in the same manner as HSOG and HSRC jointly conducted their
     business prior to the Merger.  See "Description of the Business of The
     Home-Stake Companies."

     Accounting Treatment

          The Merger will be accounted for in a manner similar to a pooling of
     interests for accounting and financial reporting purposes.  The assets and
     liabilities of HSOG and HSRC will be carried forward at their historical
     book values.  The reported income of HSOG and HSRC for prior periods will
     be combined and restated as income for the combined company.  As a result,
     all of the companies' financial statements will be presented as one company
     on both a prospective and historical basis.

     Federal Income Tax Consequences

          The following summary is a general discussion, based on current law,
     of the material federal income tax consequences applicable to holders of
     HSRC Common Stock and HSOG Common Stock who receive New HSOG Common Stock
     pursuant to either the Merger or the Stock Split.  This summary discusses
     only certain federal income tax consequences to citizens or residents of
     the United States and domestic corporations and partnerships which hold
     HSRC Common Stock or HSOG Common Stock as a capital asset.  It does not
     discuss the tax consequences that might be relevant to holders of HSRC
     Common Stock or HSOG Common Stock entitled to special treatment under
     federal income tax laws (such as individual retirement accounts and other
     tax deferred accounts, life insurance companies, and tax exempt
     organizations).

                                      -26-
<PAGE>
 
          Both HSOG and HSRC contemplate that the Merger and the Stock Split
     will qualify as reorganizations under Section 368(a) of the Code
     ("Reorganizations").  No ruling from the Internal Revenue Service has been
     or will be sought as to such qualification.  Instead, HSOG and HSRC will
     rely upon an opinion of counsel to the effect that the Merger and the Stock
     Split will qualify as Reorganizations.  Conner & Winters, A Professional
     Corporation, counsel to HSOG and HSRC, will render an opinion to HSOG and
     HSRC at the Effective Time of the Merger to the effect that the Merger and
     the Stock Split, if consummated in accordance with the Merger Agreement,
     will constitute Reorganizations under currently applicable law.  A
     preliminary version of such opinion is an exhibit to the Registration
     Statement.

          If the Merger and the Stock Split qualify as Reorganizations, a HSRC
     or HSOG stockholder whose HSRC Common Stock or HSOG Common Stock is
     converted into the right to receive solely New HSOG Common Stock pursuant
     to the Merger or Stock Split will not be subject to federal income tax by
     reason of the Merger or the Stock Split and that stockholder's tax basis in
     the New HSOG Common Stock received will be the same as such stockholder's
     tax basis in the HSRC Common Stock or HSOG Common Stock exchanged therefor.

          In general, HSRC or HSOG stockholders who exercise their appraisal
     rights will be treated as having received their payment of cash in
     redemption of their stock.  Each such stockholder will realize gain or loss
     equal to the amount his or her redemption proceeds exceeds or is exceeded
     by his or her adjusted federal income tax basis in the shares of HSRC
     Common Stock or HSOG Common Stock redeemed. Such gain or loss will be a
     capital gain or loss if the shares redeemed are held by such stockholder as
     a capital asset.

          Treasury Regulations require that each HSRC and HSOG stockholder who
     receives shares of New HSOG Common Stock (or cash in the event of an
     exercise of appraisal rights) in connection with the Merger or the Stock
     Split must incorporate into his or her income tax return for the taxable
     year in which the Merger and the Stock Split take place a statement of all
     facts pertinent thereto, including (i) a statement of the cost or other
     basis of his or her HSRC or HSOG Common Stock and (ii) a statement of the
     amount of New HSOG Common Stock or cash received.  Treasury Regulations
     further require that HSRC and HSOG stockholders maintain permanent records
     with respect to the Merger or the Stock Split, as appropriate.

          Neither HSRC nor HSOG will recognize any gain or loss by reason of the
     Merger or the Stock Split if the Merger and the Stock Split qualify as
     Reorganizations.

          THE FOREGOING IS ONLY A GENERAL DESCRIPTION OF THE MATERIAL FEDERAL
     INCOME TAX CONSEQUENCES OF THE MERGER AND THE STOCK SPLIT TO HSRC AND HSOG
     STOCKHOLDERS UNDER CURRENT LAW, WITHOUT REGARD TO THE PARTICULAR FACTS AND
     CIRCUMSTANCES OF EACH HSRC OR HSOG STOCKHOLDER'S TAX SITUATION AND STATUS.
     ACCORDINGLY, ALL HSRC AND HSOG STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN
     TAX ADVISORS WITH RESPECT TO THE FEDERAL, STATE, LOCAL AND FOREIGN TAX
     CONSEQUENCES OF THE MERGER AND THE STOCK SPLIT.

     Interests of Certain Persons in the Merger

          In considering the recommendation of the Boards of Directors of HSOG
     and HSRC with respect to the Merger Agreement and the transactions
     contemplated thereby, stockholders should be aware that certain members of
     the management of HSOG and HSRC and the Boards of Directors of HSOG and
     HSRC have certain interests in the Merger that are in addition to the
     interests of stockholders of HSOG and HSRC generally.

          The Board of Directors of HSOG has adopted the HSOG 1997 Incentive
     Stock Plan, subject to the approval of HSOG stockholders and consummation
     of the Merger.  If the Stock Plan is approved and the Merger is
     consummated, HSOG's directors and executive officers will be eligible under
     the plan to receive awards of options to purchase shares of New HSOG Common
     Stock or shares of restricted stock.  See "Approval of the HSOG 1997
     Incentive Stock Plan."

     Appraisal Rights

          Under Section 1091 of the Oklahoma General Corporation Act ("Section
     1091"), holders of shares of either HSOG Common Stock or HSRC Common Stock
     ("Shares") may demand an appraisal of the fair value of their Shares and
     payment in cash in lieu of accepting the shares of New HSOG Common Stock
     issuable to them in connection with the Merger.  Section 1091 is reprinted
     in its entirety as Appendix C to this Proxy Statement/Prospectus.  All
     references to a "stockholder" in Section 1091 and this summary thereof are
     to the record holder of Shares as to which appraisal rights are asserted.
     A person having a beneficial interest in Shares that are held of record in
     the name of another person, such as a broker or nominee and who desires to
     exercise appraisal rights, must act promptly to cause the record holder to
     follow properly the steps summarized below and in a timely manner to
     perfect the appraisal rights the beneficial owner may have.

          HSOG and HSRC must each notify their respective stockholders, not less
     than 20 days prior to their respective Special Meeting, that appraisal
     rights are available and provide each such stockholder a copy of Section
     1091 (this Proxy Statement/Prospectus constitutes such notice).
     Stockholders of record who desire to exercise their appraisal rights must:
     (i) hold Shares on the date of making a demand for appraisal, (ii)
     continuously hold Shares through the Effective Time, (iii) deliver, prior
     to the Special Meeting, a written demand for appraisal to HSOG or HSRC, as
     appropriate, at 15 East 5th Street, Suite 2800, Tulsa, Oklahoma 74103,
     Attention: Chris K. Corcoran, Executive Vice President, Chief Financial
     Officer and Secretary, and (iv) otherwise satisfy all of the following
     conditions. Although a stockholder must not have voted in favor of the
     Merger, Section 1091 does not require that a stockholder vote against the
     Merger in order to preserve his or her appraisal rights.

          If the Merger is approved by the respective stockholders of both HSOG
     and HSRC, HSOG must, within 10 days after the Effective Time of the Merger,
     notify each dissenting stockholder who has provided written demand to the
     respective company as noted above and has not voted in favor of or
     consented to the Merger that the Merger has become effective.

          Within 120 days after the Effective Time, HSOG or any stockholder who
     has satisfied the foregoing conditions and is otherwise entitled to
     appraisal rights under Section 1091 may file a petition in an Oklahoma
     district court with proper venue ("Oklahoma District Court") demanding a
     determination of the value of Shares.  HSOG does not intend to file a
     petition or initiate any negotiations with respect to the fair value of
     these Shares.  Accordingly, stockholders who wish to properly exercise
     appraisal rights should regard it as their obligation to initiate all
     necessary action with respect to the perfection of their appraisal rights
     within the time periods prescribed in Section 1091.

          Only a holder of record of Shares is entitled to assert appraisal
     rights for Shares registered in that holder's name.  The demand should be
     executed by or for the holder of record, fully and correctly, as the
     holder's name appears on the holder's stock certificates.  If Shares are
     owned of record in a fiduciary capacity, such as by a trustee, guardian or
     custodian, execution of the demand should be made in that capacity, and if
     Shares are owned of record by more than one person, as in a joint tenancy
     or tenancy in common, the demand should be executed by or for all joint
     owners.  An authorized agent, including one of two or more joint owners,
     may execute the demand for appraisal for a holder of record; however, the
     agent must identify the record owner or owners and expressly disclose the
     fact that, in executing the demand, the agent is acting as authorized agent
     for the record owner.

          A record holder, such as a broker, who holds Shares as nominee for the
     beneficial owner thereof may exercise the holder's right of appraisal with
     respect to Shares held for all or less than all of those beneficial owners.
     In that case, the written demand should set forth the number of Shares
     covered by it.  Where no number of shares is expressly mentioned, the
     demand will be presumed to cover all shares outstanding in the name of the
     applicable record owner.

          Within 120 days after the Effective Time, any stockholder who has
     complied with the requirements for exercise of appraisal rights, as
     discussed above, is entitled, upon written request, to receive from HSOG 

                                      -28-
<PAGE>
 
     a statement setting forth the aggregate number of Shares with respect to
     which demands for appraisal have been made and the aggregate number of
     holders of those Shares. This statement must be mailed within 10 days after
     the written request therefore has been received by HSOG, or within 10 days
     after the expiration of the period for delivery of demands for appraisal,
     whichever is later.

          If a petition for appraisal is timely filed, after a hearing on the
     petition, the Oklahoma District Court will determine the stockholders
     entitled to appraisal rights and will appraise Shares owned by those
     stockholders, determining "fair value" exclusive of any element of value
     arising from the accomplishment or expectation of the Merger, together with
     a fair rate of interest, if any, to be paid upon the amount determined to
     be the fair value.  Simple or compound interest may be paid.  The judicial
     determination of the "fair value" of Shares is required to be based on all
     relevant factors involving the value of a company, including market value,
     asset value, dividends, earnings prospects, the nature of the enterprise
     and any other factors which could be ascertained as of the date of the
     Merger which aid in determining the value of such corporation. The
     presiding Oklahoma District Court shall direct payment of the fair value of
     Shares by HSOG to stockholders entitled thereto.

          Stockholders considering exercising their rights of appraisal should
     bear in mind that the fair value of their Shares determined under Section
     1091 could be more than, the same as or less than the value of the shares
     of New HSOG Common Stock they would receive if they did not seek appraisal
     of their Shares.  The costs of the appraisal proceeding may be determined
     by the Oklahoma District Court and taxed against the parties as the
     Oklahoma District Court deems equitable in the circumstances.  Upon
     application of a dissenting stockholder, the Oklahoma District Court may
     order all or a portion of the expenses of experts incurred by any
     dissenting stockholder in connection with the appraisal proceeding,
     including, without limitation, reasonable attorney's fees and the fees and
     expenses of such experts, be charged pro rata against the value of all
     Shares entitled to appraisal.

          Any stockholder who has duly demanded appraisal in compliance with
     Section 1091 will not, after the Effective Time, be entitled to vote Shares
     subject to such demand for any purpose or to receive payment of dividends
     or other distributions on such Shares, except for dividends or
     distributions payable to stockholders of record at a date prior to the
     Effective Time.

          If any stockholder who demands appraisal of his or her Shares under
     Section 1091 fails to perfect, or effectively withdraws or loses, his or
     her right to appraisal, the Shares of that holder will be converted into
     the right to receive shares of New HSOG Common Stock in accordance with the
     terms of the Merger Agreement, without any interest thereon.  A stockholder
     will fail to perfect, and will effectively lose his or her right to
     appraisal, if no petition for appraisal is filed within 120 days after the
     Effective Time or if the stockholder delivers to HSOG a written withdrawal
     of his or her demand for an appraisal, except that any attempt to withdraw
     made more than 60 days after the Effective Time requires the written
     approval of HSOG.  Furthermore, no appraisal proceeding in the Oklahoma
     District Court will be dismissed as to any stockholder without the approval
     of the Court, which approval may be conditioned upon terms that the Court
     deems just.

          Dissenting stockholders who elect to exercise appraisal rights and
     receive cash for their Shares may be subject to federal and/or state income
     tax on any gain resulting from the transaction.  See "The Merger--Federal
     Income Tax Consequences" above.  It is a condition to the consummation of
     the Merger (unless waived by HSOG), that holders of no more than 12% of the
     outstanding shares of HSOG or HSRC Common Stock exercise appraisal rights
     pursuant to Section 1091.  See "The Merger Agreement--Conditions."

          Reference is made to Appendix C to this Proxy Statement/Prospectus for
     the complete text of the provisions of Section 1091 relating to the
     appraisal rights of dissenting HSOG and HSRC stockholders.  The statements
     made in this summary are qualified in their entirety by reference to such
     Appendix C.  THE PROVISIONS OF SECTION 1091 ARE TECHNICAL IN NATURE AND
     COMPLEX.  IT IS SUGGESTED THAT ANY STOCKHOLDER WHO DESIRES TO AVAIL HIMSELF
     OR HERSELF OF HIS OR HER RIGHT TO DISSENT CONSULT INDEPENDENT LEGAL COUNSEL
     BECAUSE FAILURE TO COMPLY STRICTLY

     WITH THE PROVISIONS OF SECTION 1091 MAY PRECLUDE THE EXERCISE OF HIS OR HER
     APPRAISAL RIGHTS.

     Restrictions on Resales by Affiliates of HSRC

          All shares of New HSOG Common Stock received by HSRC stockholders in
     the Merger will be freely transferable, except that shares of New HSOG
     Common Stock received by persons who are deemed to be "affiliates" (as such
     term is defined under the Securities Act) of HSRC prior to the Merger may
     be resold by them only in transactions permitted by the resale provisions
     of Rule 145 promulgated under the Securities Act (or Rule 144 in the case
     of such persons who become affiliates of HSOG) or as otherwise permitted
     under the Securities Act. Persons who may be deemed to be affiliates of
     HSRC or HSOG generally include individuals or entities that control, are
     controlled by, or are under common control with, such party and may include
     certain officers and directors of such party as well as principal
     stockholders of such party.

     Depletion Deductions

          Under the Code, independent producers are allowed a deduction for
     federal income tax purposes for statutory depletion on eligible production
     of up to 1,000 "barrels of oil equivalent per day" (hereinafter, "BOEPD").
     This deduction is generally calculated to be 15 percent of gross revenues
     from each qualified property, subject to several limitations, and may be
     taken in amounts that exceed the tax basis of the related property.  During
     the first six months of 1997, HSOG and HSRC had approximately 2,100 BOEPD
     of combined qualified production.

          In the event the Merger is consummated, HSOG, as the surviving
     corporation, will be limited to the statutory depletion deductions on the
     first 1,000 BOEPD of eligible production and lose the otherwise allowable
     statutory depletion deduction on approximately 1,000 BOEPD qualifying
     production which resulted from having the two separate corporations (i.e.,
     the 1,000 BOEPD attributable to HSRC will be lost). If HSOG and HSRC had
     been merged effective January 1, 1996, there would have been approximately
     a $178,000 increase in the amount of income taxes paid by HSOG and HSRC. In
     addition, there would have been a decrease in the amount of allowable
     statutory depletion carryforwards available to offset future income tax.
     The exact annual income tax effect of this lost depletion deduction is
     difficult to quantify due to the complexities of the Code related to
     statutory depletion and the interaction of this deduction and other
     provisions of the Code, such as the alternative minimum tax. Assuming no
     available statutory depletion carryforwards or other offsets, a price of
     $19 per barrel of oil and a 34 percent effective statutory corporate tax
     rate, the annual income tax effect of a loss of 1,000 BOEPD of qualifying
     production for purposes of the statutory depletion deduction would be
     approximately $354,000.

                              THE MERGER AGREEMENT

               The following is a brief summary of all material provisions of
     the Merger Agreement, a copy of which is attached as Appendix A to this
     Proxy Statement/Prospectus and is incorporated herein by reference.  This
     summary is qualified in its entirety by reference to the full text of the
     Merger Agreement.

     The Merger

               Pursuant to the Merger Agreement, at the Effective Time, HSRC
     will be merged with and into HSOG.  Upon consummation of the Merger, the
     separate existence of HSRC will cease and HSOG, as the surviving
     corporation in the Merger, will continue its corporate existence under the
     laws of the State of Oklahoma.  The Amended HSOG Certificate will become
     the Certificate of Incorporation of HSOG.  See "Comparative Rights of
     Stockholders."  The directors and officers of HSOG at the Effective Time of
     the Merger will remain as the directors and officers of HSOG after the
     Merger.

               Upon the satisfaction or waiver of all conditions to the Merger,
     and provided that the Merger Agreement has not been terminated or
     abandoned, HSOG and HSRC will cause a Certificate of Merger, a copy of
     which is attached as Appendix D to this Proxy Statement/Prospectus, to be
     executed, acknowledged and filed with the Secretary of State of the State
     of Oklahoma as provided in Section 1081 of the Oklahoma General Corporation
     Act.  The time at which the Merger becomes effective is referred to as the
     "Effective Time" or the "Effective Time of the Merger."

     The Stock Split

               Pursuant to the amendment of the HSOG Certificate called for by
     the Merger Agreement, at the Effective Time the authorized shares of HSOG
     Common Stock will be increased from 100,000 shares to 12,000,000 shares,
     par value $.01 per share, and the outstanding shares of HSOG Common Stock
     (other than those held by HSRC or in the treasury of HSOG) will be split on
     a 30-for-1 basis (the "Stock Split").  The HSOG common stock issued
     pursuant to the Stock Split is herein referred to as "New HSOG Common
     Stock."

     Exchange Procedures

               Exchange of HSRC Certificates.  As promptly as practicable after
     the Effective Time of the Merger, HSOG shall cause its transfer agent or
     such other agent, acting in the capacity of exchange agent (the "Exchange
     Agent"), to mail to each holder of record of HSRC Common Stock at the
     Effective Time of the Merger a letter of transmittal, together with
     instructions and a return envelope (collectively, the "HSRC Letter of
     Transmittal") to facilitate the exchange of such holder's certificates,
     formerly representing shares of HSRC Common Stock, for a certificate
     representing the shares of New HSOG Common Stock such holder is entitled to
     receive in the Merger.  HSRC stockholders should not send in their
     certificates until they receive a HSRC Letter of Transmittal.

               Upon receipt of the HSRC Letter of Transmittal, the holder of
     record of HSRC Common Stock should complete the HSRC Letter of Transmittal
     in accordance with the instructions provided and deliver the HSRC Letter of
     Transmittal, together with all stock certificates formerly representing
     shares of HSRC Common Stock to the Exchange Agent in the return envelope
     provided.  Provided the Exchange Agent shall have received the certificates
     and related documentation completed in proper form, as soon as practicable
     after the Effective Time of the Merger, the Exchange Agent will mail to the
     holder of such HSRC Common Stock a certificate for the shares of New HSOG
     Common Stock to which the holder is entitled.  No certificates for New HSOG
     Common Stock will be delivered to a holder of record of HSRC Common Stock
     unless and until such holder shall have delivered to the Exchange Agent in
     accordance with the HSRC Letter of Transmittal, all certificates formerly
     representing the shares of HSRC Common Stock held by such holder or, if
     applicable, such documentation and security in respect of lost, stolen or
     destroyed certificates as is required by the Exchange Agent or HSOG.  No
     fractional shares of New HSOG Common Stock will be issued in connection
     with the Merger.  In lieu of any fractional shares, any holder of HSRC
     Common Stock who would otherwise be entitled 

                                      -31-
<PAGE>
 
     to a fractional share of New HSOG Common Stock will, upon surrender of his
     or her HSRC certificate, receive a whole share of New HSOG Common Stock.

               After the Effective Time of the Merger, there will be no further
     transfers on HSRC's stock transfer books of the shares of HSRC Common Stock
     issued and outstanding immediately prior to the Effective Time of the
     Merger.  If certificates representing shares of HSRC Common Stock should be
     presented to HSRC after the Effective Time of the Merger, they will be
     cancelled and exchanged as described above.  If a holder of HSRC Common
     Stock has transferred ownership of such HSRC Common Stock but the transfer
     is not registered in the stock transfer records of HSRC as of the Effective
     Time of the Merger, a certificate representing the number of shares of New
     HSOG Common Stock may be issued to the transferee if the HSRC certificate,
     when presented for exchange, is accompanied by all documents required to
     evidence and effect such transfer and to evidence that any applicable stock
     transfer taxes have been paid.

               If a certificate formerly representing HSRC Common Stock shall
     have been lost, stolen or destroyed, the Exchange Agent will deliver a
     certificate representing the shares of New HSOG Common Stock issuable
     pursuant to the Merger with respect to such lost, stolen or destroyed
     certificate only upon receipt of an affidavit as to such loss, theft or
     destruction, appropriate evidence as to ownership of such certificate by
     the claimant and, if required by HSOG, the posting of a bond in such
     reasonable amount as HSOG may direct as indemnity against any claim that
     may be subsequently made against HSOG with respect to such lost, stolen or
     destroyed certificate.

               No dividends or other distributions with respect to New HSOG
     Common Stock issued with respect to shares of HSRC Common Stock in the
     Merger will be made until the holder of HSRC Common Stock entitled thereto
     surrenders his or her HSRC certificate for exchange as described above.
     Upon such surrender, such surrendering holder (i) will be paid dividends or
     other distributions having a record date after the Effective Time of the
     Merger but on or prior to the date of surrender and a payment date on or
     prior to such date of surrender with respect to the shares of New HSOG
     Common Stock such holder is entitled to receive (less, if applicable, any
     withholding taxes that may be required with respect thereto) and (ii) will
     be entitled to receive, on the payment date, any dividends or other
     distributions having a record date after the Effective Time of the Merger
     but on or prior to the date of such surrender and a payment date after such
     date of surrender which are payable with respect to the shares of New HSOG
     Common Stock such holder is entitled to receive (less, if applicable, any
     withholding taxes that may be required with respect thereto).

               Exchange of HSOG Certificates.  As promptly as practicable after
     the Effective Time of the Merger, the Exchange Agent will mail to each
     holder of record of HSOG Common Stock at the Effective Time of the Merger a
     letter of transmittal, together with instructions and a return envelope
     (collectively, the "HSOG Letter of Transmittal") to facilitate the exchange
     of such holder's certificates, formerly representing shares of HSOG Common
     Stock, for a certificate representing the shares of New HSOG Common Stock
     such holder is entitled as a result of the Stock Split.  HSOG stockholders
     should not send in their certificates until they receive a HSOG Letter of
     Transmittal.

               Upon receipt of the HSOG Letter of Transmittal, the holder of
     record of HSOG Common Stock should complete the HSOG Letter of Transmittal
     in accordance with the instructions provided and deliver the HSOG Letter of
     Transmittal, together with all stock certificates formerly representing
     shares of HSOG Common Stock to the Exchange Agent in the return envelope
     provided. Provided the Exchange Agent shall have received the certificates
     and related documentation completed in proper form, as soon as practicable
     after the Effective Time of the Merger, the Exchange Agent will mail to the
     holder of such HSOG Common Stock a certificate for the shares of New HSOG
     Common Stock to which the holder is entitled. No certificates for New HSOG
     Common Stock will be delivered to a holder of record of HSOG Common Stock
     unless and until such holder shall have delivered to the Exchange Agent in
     accordance with the HSOG Letter of Transmittal, all certificates formerly
     representing the shares of HSOG Common Stock held by such holder or, if
     applicable, such documentation and security in respect of lost, stolen or
     destroyed certificates as is required by the Exchange Agent or HSOG.

<PAGE>
 
               If a certificate formerly representing HSOG Common Stock shall
     have been lost, stolen or destroyed, the Exchange Agent will deliver a
     certificate representing the shares of New HSOG Common Stock issuable
     pursuant to the Stock Split with respect to such lost, stolen or destroyed
     certificate only upon receipt of an affidavit as to such loss, theft or
     destruction, appropriate evidence as to ownership of such certificate by
     the claimant and, if required by HSOG, the posting of a bond in such
     reasonable amount as HSOG may direct as indemnity against any claim that
     may be subsequently made against HSOG with respect to such lost, stolen or
     destroyed certificate.

     Conditions

               The respective obligations of HSOG and HSRC to consummate the
     Merger are subject to the approval and adoption of the Merger Agreement by
     the holders of 66 2/3 percent of the outstanding shares of each of HSOG
     Common Stock and HSRC Common Stock and the satisfaction of the following
     conditions (unless waived, in certain circumstances, by such parties): (i)
     no court, arbitrator or governmental body, agency or official shall have
     issued any order, and there shall not be any statute, rule or regulation,
     restraining or prohibiting the consummation of the Merger; (ii) holders of
     not more than 12% of the outstanding shares of HSOG Common Stock or HSRC
     Common Stock shall have exercised their appraisal rights in accordance with
     Section 1091 of the Oklahoma General Corporation Act; (iii) HSOG and HSRC
     shall each have received a written opinion from Principal that the Merger
     is fair, from a financial point of view, to the stockholders of HSOG and
     HSRC, respectively, and such opinion shall not have been withdrawn; and
     (iv) HSOG and HSRC shall have each received a written opinion of Conner &
     Winters, A Professional Corporation, to the effect that the Merger will be
     treated as a reorganization under Section 368(a) of the Code and the
     regulations thereunder.

     Amendment and Termination

               Notwithstanding approval by the stockholders of HSOG and HSRC,
     the Boards of Directors of HSOG and HSRC may amend the Merger Agreement at
     any time prior to the filing of the Certificate of Merger so long as any
     such amendment does not alter (i) the amount of New HSOG Common Stock to be
     received by a HSOG or HSRC stockholder, (ii) the amendments to the HSOG
     Certificate set forth in the Certificate of Merger or (iii) any term or
     condition of the Merger Agreement, the alteration of which would adversely
     affect HSOG or HSRC stockholders.  Further, notwithstanding such approval,
     the Boards of Directors of either HSOG or HSRC may terminate the Merger
     Agreement at any time prior to such filing.

               MARKET FOR HSOG COMMON STOCK AND HSRC COMMON STOCK
                        AND RELATED STOCKHOLDER MATTERS

     HSOG

               Market Prices.  As of July 31, 1997, HSOG had approximately 200
     holders of record of its Common Stock. HSOG Common Stock is listed in the
     "pink sheets" published by the National Quotation Bureau. Historically, the
     "pink sheets" have generally identified firms acting as market makers for
     HSOG Common Stock but, to the Company's knowledge, did not set forth bid
     and ask quotations for such stock. Trades in the stock are sporadic or
     limited and, accordingly, there is no established public trading market for
     HSOG Common Stock.

          HSOG has historically paid quarterly cash dividends to its
     stockholders.  HSOG's Board of Directors has adopted a policy to pay
     quarterly dividends on HSOG Common Stock, dependent on numerous
     factors,including future earnings, anticipated capital requirements, the
     financial condition and prospects of HSOG, and other factors HSOG's Board
     may deem relevant.  Upon consummation of the Merger, HSOG's Board of
     Directors plans to continue a policy to pay quarterly dividends on the New
     HSOG Common Stock, dependent on the same considerations.  In addition,
     future dividends may be restricted pursuant to the terms of the loan
     agreement between HSOG and NationsBank, N.A.  See "Management's Discussion
     and Analysis of Financial Condition and Results of Operations--Management's
     Discussion and Analysis of Financial Conditions and Results of Operations

     these restrictions.

     HSRC

          Market Prices.  As of July 31, 1997, HSRC had approximately 300
     holders of record of its Common Stock.  HSRC Common Stock is listed in the
     "pink sheets" published by the National Quotation Bureau.  Historically,
     the "pink sheets" have generally identified the firms acting as market
     makers for HSRC Common Stock but, to the Company's knowledge, did not set
     forth bid and ask quotations for such stock.  Trades in the stock are
     sporadic or limited and, accordingly, there is no established public
     trading market for HSRC Common Stock.

          Dividends.  The following table sets forth the per share amount of
     cash dividends declared and paid on HSRC Common Stock during the periods
     indicated.

          HSRC has historically paid quarterly cash dividends to its
     stockholders.  HSRC's Board of Directors has adopted a policy to pay
     quarterly dividends on HSRC Common Stock, dependent on numerous factors,
     including future earnings, anticipated capital requirements, the financial
     condition and prospects of HSRC and such other factors as the Board of

     NationsBank, N.A.  See "Management's Discussion and Analysis of Financial
     Condition and Results of Operations--Management's Discussion and Analysis
     of Financial Condition and Results of Operations of HSRC--Financial
     Condition and Liquidity" below for a description of these restrictions.  If
     the Merger is consummated, HSRC stockholders (other than HSOG and
     stockholders who exercise their appraisal rights) will receive shares of
     New HSOG Common Stock and will be entitled to receive, if, as, and when
     declared by the Board of Directors of HSOG, dividends on such stock.  See
     the discussion under "Market For HSOG Common Stock and HSRC Common Stock
     and Related Stockholder Matters--HSOG" above for the anticipated dividend
     policy of HSOG after the Merger.

                       DESCRIPTION OF HSOG CAPITAL STOCK

          The authorized capital stock of HSOG currently consists of 100,000
     shares of HSOG Common Stock, $20 par value per share, and 200,000 shares of
     Preferred Stock, $1.00 par value per share ("HSOG Preferred Stock").
     After the Merger, the authorized capital stock of HSOG will consist of
     12,000,000 shares of New HSOG Common Stock, $.01 par value per share, and
     2,000,000 shares of HSOG Preferred Stock, $1.00 par value per share.  No
     class of capital stock of HSOG entitles (or, after the Merger, will
     entitle) the holder thereof to any preemptive rights to purchase or
     subscribe for shares of any class or any other securities.

          The following description of the capital stock of HSOG is subject to
     the provisions of HSOG's Certificate of Incorporation as currently in
     effect (the "HSOG Certificate") and as amended in connection with the
     Merger (the "Amended HSOG Certificate") and bylaws as currently in effect
     (the "HSOG Bylaws").  For a more complete description of the HSOG
     Certificate, Amended HSOG Certificate and HSOG Bylaws, reference is made to
     the full text of the HSOG Certificate and the HSOG Bylaws and to the
     amendment to the HSOG Certificate which is set forth in the Certificate of
     Merger, a copy of which is attached as Appendix D to this Proxy
     Statement/Prospectus.

          HSOG Common Stock and New HSOG Common Stock.  All issued and
     outstanding shares of HSOG Common Stock are validly issued, fully paid and
     nonassessable, and the shares of New HSOG Common Stock to be issued in the
     Merger, when issued pursuant to the Merger Agreement, will be validly
     issued, fully paid and nonassessable.  The holders of either HSOG Common
     Stock or New HSOG Common Stock are entitled to one vote for each share held
     on all matters submitted to a vote of common stockholders, 

                                      -35-
<PAGE>
 
     including the election of directors. Neither HSOG Common Stock nor New HSOG
     Common Stock has cumulative voting rights. Each share of either HSOG Common
     Stock or New HSOG Common Stock is entitled to participate equally in
     dividends, as and when declared by the HSOG Board of Directors out of funds
     legally available therefor, and in the distribution of assets in the event
     of liquidation, subject in all cases to any prior rights of outstanding
     shares of HSOG Preferred Stock or New HSOG Preferred Stock. Neither shares
     of HSOG Common Stock nor shares of New HSOG Common Stock have preemptive or
     conversion rights, redemption rights or sinking fund provisions.

          Upon consummation of the Merger there will be approximately 7,500,000
     shares of authorized but unissued shares of New HSOG Common Stock.
     Management of HSOG believes that the ability of the HSOG Board to issue
     additional shares of New HSOG Common Stock provides HSOG with flexibility
     in structuring possible future financings and acquisitions and in meeting
     other corporate needs that might arise.  Although the HSOG Board has no
     intention at the present time of doing so, it could issue additional shares
     of New HSOG Common Stock that could impede the completion of a merger,
     tender offer or other takeover attempt.  See "Risk Factors--Authorized But
     Unissued Shares of New HSOG Common Stock" and "--Certain Provisions and
     Arrangements That May Have an Anti-Takeover Effect" below.

          HSOG Preferred Stock.  Pursuant to the HSOG Certificate, HSOG is
     authorized to issue up to 200,000 shares of HSOG Preferred Stock, and the
     HSOG Board of Directors by resolution may establish one or more series of
     HSOG Preferred Stock having the number of shares, designations, relative
     voting rights, dividend rights, liquidation and other rights, preferences
     and limitations that the HSOG Board of Directors fixes without any
     stockholder approval.  Pursuant to the Amended HSOG Certificate, the
     authorized shares of HSOG Preferred Stock will be increased to 2,000,000
     shares.  The issuance of HSOG Preferred Stock may adversely affect the
     rights of the holders of HSOG Common Stock or New HSOG Common Stock.  As of
     the date of this Proxy Statement/Prospectus, no shares of HSOG Preferred
     Stock have been issued and no series of HSOG Preferred Stock has been
     designated by the HSOG Board of Directors.

          Management of HSOG believes that the ability of the HSOG Board to
     issue one or more series of HSOG Preferred Stock provides HSOG with
     flexibility in structuring possible future financings and acquisitions and
     in meeting other corporate needs that might arise.  Although the HSOG Board
     has no intention at the present time of doing so, it could issue a series
     of HSOG Preferred Stock that could, depending on the terms of such series,
     impede the completion of a merger, tender offer or other takeover attempt.
     See "--Certain Provisions and Arrangements That May Have an Anti-Takeover
     Effect" below.

     Certain Provisions and Arrangements That May Have an Anti-Takeover Effect

          Certain provisions of the HSOG Certificate and Bylaws may have an 
     anti-takeover effect in that they could prevent, discourage or delay a 
     change in control of HSOG. Certain arrangements and provisions of the
     Oklahoma General Corporation Act may also have a similar effect. The
     following summary briefly describes certain of these provisions and
     arrangements. The summary is not intended to be complete and is qualified
     in its entirety by reference to the document or provision of the Oklahoma
     General Corporation Act which is the subject of the description. As noted
     below, most of the provisions or arrangements that may have an anti-
     takeover effect currently apply to HSOG and HSRC due to provisions in the
     HSOG and HSRC certificates of incorporation and bylaws and outstanding
     arrangements. See "Comparative Rights of Stockholders."

          Classified Board

               The HSOG Bylaws provide for the Board of Directors of HSOG to be
          divided into three classes, with members of each class serving
          staggered three-year terms.  The Oklahoma General Corporation Act
          provides that members of a classified Board of Directors can only be
          removed by the stockholders for cause absent a provision in a
          corporation's certificate of incorporation to the contrary.  The HSOG
          Certificate does not contain such a provision, and thus, the HSOG
          stockholders must have cause in order to remove a member of the HSOG
          Board of Directors.  The HSRC Bylaws 

                                      -36-
<PAGE>
 
          similarly provide for classified Boards of Directors for HSRC. See
          "Comparative Rights of Stockholders--Number of Directors; Removal of
          Directors; Filling Vacancies; Qualifications."

          Stockholder Action

               The HSOG Certificate provides that stockholders may only take
          action without a meeting by obtaining the written consent of all
          stockholders entitled to vote on such action.  Absent obtaining such
          unanimous written consent, stockholder action will require a meeting
          of stockholders which will allow all stockholders to receive prior
          notice of proposed action and to discuss and vote on such action.  The
          HSRC Certificate contains similar provisions requiring unanimous
          written consent to stockholder action without a meeting.  See
          "Comparative Rights of Stockholders--Stockholder Action by Written
          Consent; Special Meetings."

          Common Stock

               Upon consummation of the Merger there will be approximately
          7,500,000 shares of authorized but unissued shares of New HSOG Common
          Stock.  The authorized but unissued shares of New HSOG Common Stock
          could be used by incumbent management to make more difficult a change
          in control of HSOG.  Under certain circumstances, such shares could be
          used to create voting impediments or to frustrate persons seeking to
          effect a takeover or otherwise gain control of HSOG.  The shares of
          authorized but unissued New HSOG Common Stock might also be considered
          as having the effect of discouraging an attempt by another person,
          through the acquisition of a substantial number of shares of New HSOG
          Common Stock, to acquire control of HSOG with a view of imposing a
          merger, sale of all or any part of HSOG's assets or a similar
          transaction, since the issuance of additional shares could be used to
          dilute the stock ownership and voting power held by such person.  Any
          transaction which may be so discouraged or avoided could be a
          transaction that HSOG's stockholders might consider to be in their
          best interests, although it should be noted that the Board of
          Directors of HSOG has a fiduciary duty to act in the best interests of
          HSOG's stockholders.

          Preferred Stock

               The Amended HSOG Certificate authorizes up to 2,000,000 shares of
          undesignated HSOG Preferred Stock. HSOG Preferred Stock may be issued
          from time to time in one or more series, and the HSOG Board of
          Directors, without further approval of the stockholders, is authorized
          to fix and state the designation, powers, preferences and other rights
          of the shares and each series of HSOG Preferred Stock. One of the
          effects of the existence of the authorized but unissued HSOG Preferred
          Stock may be to enable the HSOG Board of Directors to render more
          difficult or discourage an attempt to obtain control of HSOG by means
          of a merger, tender offer, proxy contest or otherwise, and thereby
          protect the continuity of HSOG's management. For example, if in the
          exercise of its fiduciary obligations the HSOG Board of Directors were
          to determine that a takeover proposal was not in HSOG's best interest,
          HSOG Preferred Stock could be issued by the HSOG Board of Directors
          without stockholder approval in a transaction or transactions that
          might prevent or render more difficult or costly the completion of the
          takeover transaction by diluting the voting or other rights of the
          proposed acquiror or insurgent stockholder or stockholder group, by
          creating a substantial voting block in institutional or other hands
          that might undertake to support the position of the incumbent HSOG
          Board of Directors, by effecting an acquisition that might complicate
          or preclude the takeover, or otherwise. In this regard, the HSOG Board
          of Directors could issue, in one or more series, HSOG Preferred Stock
          entitling holders to vote separately as a class on any proposed merger
          or consolidation, to convert HSOG Preferred Stock into a larger number
          of shares of HSOG Common Stock or other securities, to demand
          redemption at a specified price under prescribed circumstances related
          to a change in control, or to exercise other rights designed to impede
          a takeover. The issuance of shares of HSOG Preferred Stock pursuant to
          the HSOG Board's authority described above could decrease the amount
          of earnings and assets available for distribution to holders of HSOG
          Common Stock, and adversely affect the rights and powers, including
          voting rights, of such 

                                      -37-
<PAGE>
 
          holders and may have the effect of delaying, deferring or preventing a
          change in control of HSOG. The HSOG and HSRC Certificates authorize
          classes of undesignated Preferred Stock that could have the anti-
          takeover effects noted above. See "--HSOG Preferred Stock" and
          "Comparative Rights of Stockholders--'Blank Check' Preferred Stock."

          Business Combination Statute

               Upon consummation of the Merger, HSOG will likely become subject
          to provisions (the "Business Combination Statute") of the Oklahoma
          General Corporation Act that may have the effect of preventing,
          discouraging or delaying a change in control of HSOG.  The
          restrictions of the Business Combination Statute are applicable to any
          Oklahoma corporation that has a class of stock listed on the NASDAQ
          National Market.  The Business Combination Statute generally
          prohibits certain business combinations between a corporation and any
          person who has acquired 15% or more of the voting stock of the
          corporation (an "interested shareholder") for a period of three years
          from the date such shareholder became an interested shareholder,
          unless such interested shareholder (i) prior to becoming an interested
          shareholder, obtained the approval of the board of directors of either
          the business combination or the transaction that resulted in such
          person becoming an interested shareholder, (ii) acquired at least 85%
          of the outstanding shares of voting stock of the corporation
          (excluding shares owned by persons who are directors, officers and by
          certain employee stock plans) in the same transaction in which the
          interested shareholder became an interested shareholder or (iii) if on
          or subsequent to the date the interested shareholder became an
          interested shareholder, the business combination is approved by the
          board of directors and is authorized at a meeting of stockholders by
          the affirmative vote of at least two-thirds of the voting stock that
          is not owned by the interested shareholder.  See "Comparative Rights
          of Stockholders--Business Combinations."

               HSOG and HSRC are currently not subject to the Business
          Combination Statute.  However, the HSOG and HSRC Certificates provide
          that any merger, consolidation, sale of a substantial portion of
          assets, dissolution or other reorganization or business combination
          requires the approval of the holders of at least 66 2/3 percent of
          stock entitled to vote thereon. The HSOG Board has proposed an
          amendment to the HSOG Certificate to eliminate the 66 2/3 percent vote
          and, if such amendment is approved by the HSOG stockholders, such
          transactions may be approved by the affirmative vote of holders of at
          least a majority of the outstanding shares entitled to vote on such
          issues so long as the Business Combination Statute is not applicable
          to such a transaction. See "Comparative Rights of Stockholders--
          Business Combinations" and "Amendments to the Certificate of
          Incorporation of HSOG."

          Control Shares Provisions

               Certain provisions of the HSOG Certificate limit the right of any
          person or group of persons that acquires (except in limited
          circumstances such as mergers) voting power with respect to one-fifth
          or more of certain corporations' shares to vote such shares unless
          granted voting rights by the holders of a majority of the votes
          entitled to be cast excluding "interested shares."  If the approval of
          voting power for the shares is obtained, additional stockholder
          approvals are required when a stockholder acquires the power to vote
          one-third or more and a majority or more of the voting power of the
          corporation's shares. In the absence of such approval, the additional
          shares acquired by the stockholder may not be voted until the
          expiration of three years after the date of a vote of stockholders
          failing to approve the voting power of such shares.  The HSRC
          Certificate contains provisions which are identical to the HSOG
          Certificate.   See "Comparative Rights of Stockholders--Control
          Shares."

          Rights Agreement

               Both HSOG and HSRC currently have in place identical Rights
          Agreements.  It is currently contemplated that HSOG's Rights Agreement
          will continue after the Merger.  Pursuant to the Rights 

                                      -38-
<PAGE>
 
          Agreement dated May 29, 1991, as amended April 15, 1992 and February
          10, 1995 (the "Rights Agreement"), between HSOG and The Fourth
          National Bank of Tulsa (now NationsBank, N.A.), in the event that
          beneficial control of 15% or more of New HSOG Common Stock is acquired
          by a person or group, the stockholders of HSOG, other than such person
          or group, will have the right to acquire, for each share of New HSOG
          Common Stock which they hold, one additional share of New HSOG Common
          Stock at a price equal to one-half of the then current market price
          per share. In the event HSOG does not have a sufficient number of
          authorized shares available to issue the shares necessary to satisfy
          those stockholders exercising their rights under the Rights Agreement,
          HSOG's Board of Directors is authorized to take other action,
          including causing HSOG to issue stockholder rights to acquire other
          types of securities in lieu of New HSOG Common Stock. See "Comparative
          Rights of Stockholders--Rights Agreement."

          Change in Control Severance Plan

               HSOG has a plan in place which is designed to provide severance
          payments in the event that all or substantially all of the assets or
          stock of HSOG are acquired by another unrelated party and, if by
          reason of such acquisition, an eligible employee's employment with
          HSOG terminates and no reasonable alternative employment by the
          acquiring entity is offered.  HSRC has a substantially similar plan in
          place.  The Merger will not trigger the change in control provisions
          of the severance plan of HSOG or of HSRC.  It is currently
          contemplated that the HSOG severance plan will continue after the
          Merger.  See "Security Ownership of Certain Beneficial Owners;
          Compensation and Other Information Concerning Officers and Directors-
          -Change in Control Severance Plans."

          Employment Contract

               Robert C. Simpson has an employment agreement to serve as Chief
          Executive Officer, President and Treasurer of HSOG and HSRC which
          renews automatically on an annual basis. The agreement provides that
          Mr. Simpson is entitled to receive certain payments in the event of
          his termination or constructive termination during or after a change
          in control of HSOG or HSRC. The Merger will not trigger the change in
          control provisions of Mr. Simpson's employment agreement. Subsequent
          to the Merger, HSOG will become obligated for 100% of Mr. Simpson's
          salary and other benefits under the employment agreement. See
          "Security Ownership of Certain Beneficial Owners; Compensation and
          Other Information Concerning Officers and Directors--Employment
          Contracts."

          The provisions described above might be deemed to make HSOG less
     attractive as a candidate for acquisition by another company than would
     otherwise be the case in the absence of such provisions.  As a result, HSOG
     stockholders may be deprived of opportunities to sell some or all of their
     shares at prices that represent a premium over prevailing market prices in
     a takeover context.  The provisions described above may also make it more
     difficult for HSOG stockholders to replace the HSOG Board of Directors or
     management, even if the holders of a majority of the New HSOG Common Stock
     should believe that such replacement is in the interests of HSOG.  As a
     result, such provisions may tend to perpetuate the incumbent HSOG Board of
     Directors and management.

                       COMPARATIVE RIGHTS OF STOCKHOLDERS

     General

          As a result of the Merger, holders of HSRC Common Stock (other than
     holders who exercise their appraisal rights) will become holders of New
     HSOG Common Stock and holders of HSOG Common Stock (other than holders who
     exercise their appraisal rights) will have their shares converted into
     shares of New HSOG Common Stock.  The rights of holders of HSOG Common
     Stock and HSRC Common Stock are substantially the same because HSOG and
     HSRC are both Oklahoma corporations and because the HSOG Certificate and
     the HSOG Bylaws contain provisions that are virtually identical to those
     found in HSRC's Certificate of Incorporation as currently in effect (the
     "HSRC Certificate") and HSRC's bylaws as currently in 

                                      -39-
<PAGE>
 
effect (the "HSRC Bylaws"). The rights of all holders of New HSOG Common Stock
will be governed by the Amended HSOG Certificate and the HSOG Bylaws.

     The following is a summary of the material rights of holders of New HSOG
Common Stock and the differences between those rights and the rights of holders
of HSRC Common Stock. Because both HSRC and HSOG are organized and exist under,
and are subject to, the corporate laws of Oklahoma and because the HSOG
Certificate and HSOG Bylaws are substantially similar to the HSRC Certificate
and HSRC Bylaws, there are relatively few differences between the rights of
holders of New HSOG Common Stock after consummation of the Merger and the rights
of holders of HSRC Common Stock. The HSOG Board has submitted several proposed
amendments to the HSOG Certificate for approval by the HSOG stockholders at the
HSOG Meeting. The proposed amendments, if approved by HSOG stockholders, will
only become effective if the Merger is consummated. Stockholders of HSOG and
HSRC should carefully review the discussion under "Amendments to the Certificate
of Incorporation of HSOG" in this Proxy Statement/Prospectus for complete
description of the proposed amendments and the effects thereof. For a more
complete description of the following rights and differences, reference is made
to the full text of the HSOG Certificate, the Amended HSOG Certificate, the HSOG
Bylaws, the HSRC Certificate and the HSRC Bylaws.

thereon. The HSOG Board has submitted           
a proposed amendment to the HSOG     
Certificate which would not require      
any "supermajority" vote of the       
stockholders to approve a merger or           
other form of business combination.     
Consequently, such transactions       
may be approved by the affirmative                
vote of holders of at least a     
majority of the outstanding shares

New HSOG Common Stock will be listed 
on the NASDAQ National Market.  In 
such case, HSOG and its stockholders 
will become subject to the provisions
of the "Business Combination Statute" 
of the Oklahoma General Corporation 
Act.  These provisions may have the 
effect of preventing, discouraging or
delaying a change in control of HSOG.  
See "Description of HSOG Capital 
Stock--Certain Provisions and 
Arrangements That May Have an 
Anti-Takeover Effect" for a discussion 
of the provisions of the Business 
Combination Statute.                
                                        
    Under certain circumstances, the Business Combination Statute, as described
above, may make it difficult for a person who would be an "interested
stockholder" to effect various business combinations with a corporation for a
three-year period. The provisions of the Business Combination Statute may
encourage companies interested in acquiring HSOG to negotiate in advance with
the HSOG Board, since the stockholder approval requirement would be avoided if a
majority of the directors then in office approve either the business combination
or the transaction that results in the stockholder becoming an interested
stockholder.

for a discussion of the control

                               Appraisal Rights

     HSOG and HSRC. Under Section 1091 of the Oklahoma General Corporation Act
stockholders generally have the right to demand and receive payment for the fair
value of their stock in connection with certain mergers and consolidations;
provided, however, no such appraisal rights are available with respect to shares
of any class or series of stock listed on a national securities exchange or held
of record by more than 2,000 stockholders. HSOG and HSRC are Oklahoma
corporations and are subject to Section 1091. Neither HSOG Common Stock nor HSRC
Common Stock is traded on a national securities exchange or held of record by
more than 2,000 stockholders; thus, HSOG and HSRC stockholders currently have
appraisal rights in connection with certain mergers and consolidations and
specifically with respect to the Merger. After the Merger is consummated, HSOG
stockholders (including former HSRC stockholders) will continue to have
appraisal rights available to them with respect to the New HSOG Common Stock
until such time, if ever, that such shares are listed on a national securities
exchange or held of record by more than 2,000 stockholders. See "The Merger--
Appraisal Rights."

     In addition, as discussed in greater detail under "Amendment to the
Certificate of Incorporation of HSOG" and "Proposed Amendment No. 8" thereunder,
the stockholders of HSOG may have the right to exercise dissenters' appraisal
rights under the "old" Oklahoma Business Corporation Act with respect to certain
actions (i) deemed to have an adverse affect on a class of stockholders, (ii)
reducing the number of directors or (iii) changing or altering the corporate
purpose. The Oklahoma General Corporation Act does not specifically provide for
appraisal rights for such actions. The Board of Directors has submitted a
proposed amendment to the HSOG Certificate that HSOG be governed by the Oklahoma
General Corporation Act, which, if adopted, would eliminate any possible
appraisal rights existing under the old Oklahoma Business Corporation Act. See
"Amendments to the Certificate of Incorporation of HSOG."

                   Indemnification; Advancement of Expenses

     HSOG.  The HSOG Bylaws require         HSRC.  The HSRC Bylaws contain     
HSOG to indemnify officers, directors,  provisions relating to the             
employees and agents for actions        indemnification of directors, officers,

with respect to any criminal
action, which they had no reasonable
cause to believe was unlawful.   The
HSOG Bylaws provide that HSOG may
advance expenses of defense (upon
receipt of a written undertaking to
reimburse the corporation if
indemnification is not appropriate)
and must reimburse a successful
defendant for expenses, including
attorneys' fees, actually and
reasonably incurred.  The HSOG
Bylaws permit HSOG to purchase and
maintain liability insurance for
its directors and officers.  The
HSOG Bylaws provide that
indemnification may not be made for
any claim, issue or matter as to
which a person has been adjudged by
a court of competent jurisdiction,
after exhaustion of all appeals
therefrom, to be liable to HSOG,
unless and only to the extent such
court determines that the person is
entitled to indemnity for such
expenses, despite the adjudication
of liability, as the court deems
proper.  The HSOG Bylaws provide 
that the indemnification rights are 
not exclusive of any other right to 
which a person seeking indemnification 
may be entitled under any law, bylaw,
agreement, vote of stockholders or
disinterested directors or
otherwise.  The HSOG Board has
submitted a proposed amendment to
the HSOG Certificate which provides
that HSOG may, as determined by the
HSOG Board, indemnify and advance
expenses to a director, officer,
employee or agent to the maximum
extent permitted by Section 1031 of
the Oklahoma General Corporation
Act (discussed under "Amendments to
the Certificate of Incorporation of
HSOG").  The provisions of Section
1031 are substantially similar to
the provisions currently contained
in the HSOG Bylaws.  See "Amendments

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

Management's Discussion and Analysis of Financial Condition and Results of
Operations of HSOG

     The following discussion should be read in conjunction with HSOG's
financial statements and notes thereto included elsewhere herein.

Results of Operations

     Six Months Ended June 30, 1997 Compared to Six Months Ended June 30, 1996.

     Net income for the first six months increased $432,002 from $509,661 in
1996 to $941,663 in 1997. The principal reasons for this increase are as
follows:

     Oil sales decreased 1% ($26,746) as a result of a decrease in production
volumes of 7,518 barrels, partially offset by an increase in the average price
of oil from $19.00 per barrel in 1996 to $20.04 per barrel in 1997. The decrease
in production volumes was primarily a result of property dispositions during
1996 and early 1997.

     Gas sales increased $266,197 (24%) due to an increase in the average gas
price per mcf from $1.92 in 1996 to $2.43 in 1997, partially offset by a
decrease in production volumes from 584,244 Mcf in 1996 to 571,364 Mcf in 1997.

     Lease rentals and bonuses increased $33,363 due to higher leasing activity
with respect to HSOG's mineral interests in 1997 than in 1996.

     Interest income increased $3,762 from 1996 primarily as a result of greater
excess funds available for investment.

     Gain on sales of assets increased $96,843 in 1997 following HSOG's sale of
its interest in the N.E. Alden Field. There were no comparable sales in 1996.

     Income from equity affiliates increased $50,095 in 1997. HSOG's principal
equity investee, HSRC, reported net income of $1,091,138 in 1997 and $764,270 in
the same period of 1996. In addition, HSOG's ownership in HSRC increased from
17.1% to 19.3% in November 1996.

     Other income was $12,650 higher due to additional "administrative overhead"
being collected from joint interest owners on HSOG operated wells and $9,500
received from the purchaser of the N.E. Alden field properties for HSOG's
operation of the properties while the purchaser satisfied certain title
requirements.

     Lease operating expenses decreased $258,349 (25%) from 1996. This decrease
is principally attributable to environmental remediation expenses in 1996
associated with a waterflood property in which HSOG has a 9% working interest,
coupled with an insurance reimbursement in 1997 of certain of such costs of
approximately $145,250

     Dry hole costs increased $228,996 in 1997 due to a greater incidence of dry
holes. In 1996, there were 3 dry holes (.16 net) drilled at an average gross
cost of $288,200 per well; in 1997, there were 6 dry holes (.61 net) drilled at
an average gross cost of $451,000 per well.

     Condemned and abandoned property expense increased $46,110. 1996 expense
was a net credit of $5,075, primarily the result of salvage credits of $12,488
received on a property abandoned during the first 


                                     -46-
<PAGE>
 
quarter. 1997 expense was also higher due to the abandonment of acreage costs
associated with six dry holes in 1997, compared to two in 1996.

     General and administrative expense increased $70,085 (15%). This increase
is primarily associated with the addition of certain full-time and contract
employees in late 1996 and early 1997. Such personnel were added in anticipation
of an increase in HSOG's exploration activities.

     Interest expense decreased $92,366 in 1997, reflecting HSOG's lower average
borrowings.

     Year Ended December 31,1996 Compared to Year Ended December 31, 1995.

     Net income for 1996 increased 236% from $428,185 in 1995 to $1,437,674 in
1996. The factors contributing to this increase are as follows:

     Oil sales increased $1,060,434 (29%) primarily as a result of an increase
in the average sales price per barrel from $16.17 in 1995 to $20.19 in 1996,
coupled with an increase in production of 7,447 barrels. The increase in
production was contributed by producing properties HSOG acquired in 1995 and
1996, along with new drilling in 1996.

     Gas sales increased 36% ($631,085) as a result of an increase in the
average sales price from $1.41 per Mcf in 1995 to $2.00 per Mcf in 1996,
partially offset by a 4% decrease in production.

     Interest income increased $7,004 primarily as a result of more excess funds
available for investment.

     Gains on sales of assets increased 155% ($102,695) in 1996. HSOG had two
major property sales in 1996. In November, HSOG sold its interest in a
Montgomery County, Texas field at a gain of $140,730. In December, HSOG sold its
interest in 55 small, marginal properties at a small gain.

     Income from equity affiliates increased by $165,455. In 1996, HSOG's
principal equity investee, HSRC, reported net income of $1,844,161 compared to
$620,835 in 1995.

     Lease operating expenses increased $850,865 (54%) due primarily to non-
recurring costs incurred in the settlement of claims by surface owners and the
remediation of saltwater contamination on a property in which HSOG owns a 9%
working interest. Excluding this property, lease operating expenses increased
$281,889. This increase was associated with properties HSOG acquired during 1995
and 1996, for which there are not comparable period-costs in the two years. In
December 1996 and March 1997, HSOG sold several marginal properties that
incurred high operating costs. The properties sold incurred lease operating
expenses in 1996 of $229,140.

     Production taxes increased $194,674 as a result of the higher oil and gas
sales described above.

     Dry hole costs decreased 40% ($71,825) in 1996. In 1996 there were 5 dry
holes drilled (.36 net) at an average cost of $292,725 per net well; in 1995
there were 5 dry holes (.63 net) drilled at an average cost of $280,400 per net
well.

     Condemned and abandoned property expense decreased $31,225 (38%). 1996
expense includes salvage credits of $12,488 received on a property abandoned
during the first quarter. 1995 expense was unusually high due to the non-
recurring abandonment of acreage costs associated with three dry holes, coupled
with the expiration of leases on certain non-producing acreage owned by HSOG.

     General and administrative expense decreased $272,345 (26%) in 1996.
General and administrative expense incurred in 1995 included approximately
$139,600 related to HSOG's unsuccessful proposed merger with HSRC. The 1996
expense includes a credit in the amount of $82,500, representing the
reimbursement of legal expenses from HSOG's Directors' and Officers' liability
insurance carrier. This amount was received 


                                     -47-
<PAGE>
 
in settlement of a suit HSOG and HSRC brought against the carrier for recovery
of certain costs incurred by HSOG in the successful defense of HSOG's directors
in a lawsuit commenced in 1991.

     HSOG's effective tax rate varies significantly from year to year, due
principally to the significant effects of statutory depletion which is largely
independent of pre-tax income. In addition, a portion of net income each year is
attributable to HSOG's equity income from HSRC, for which there is no
corresponding income tax provision required. For additional information
attributable to each of these factors see Note 4 to the Consolidated Financial
Statements on page F-23.

Financial Condition and Liquidity

     HSOG's operating activities have traditionally been self-financed through
internally generated cash flows. The principal uses of cash flows have been to
fund HSOG's exploration and production activities and for the payment of
dividends to stockholders. The use of borrowed funds has generally been limited
to the acquisition of producing oil and gas properties where future revenues
from such purchases are expected to fund the debt.

     In 1996, HSOG spent $481,000 for exploration and development activities and
$217,000 on acquisitions. HSOG has budgeted $1.0 million for exploration and
development activities in 1997. HSOG has expended approximately $496,000 for
such activities through June 30, 1997, and has current commitments of
approximately $1.2 million for the remainder of 1997 and into 1998.

     HSOG's working capital deficit at June 30, 1997, was approximately
$930,000. Since the beginning of 1997, product prices for oil and natural gas
decreased approximately 20% and 45%, respectively. Despite these decreases in
product prices, HSOG expects to finance its working capital deficit and budgeted
1997 exploration and development activities from internally generated cash
flows. In addition, HSOG maintains a line of credit described below which
extends into 1998.

     HSOG's outstanding bank note is due May 1, 1998. Principal payments under
the note are $114,110 per month, plus interest. The outstanding indebtedness
accrues interest at bank prime less one-half of one percent and is secured by
certain of HSOG's producing properties. In addition, HSOG has a revolving line
of credit with a bank in the amount of $500,000 which expires May 1, 1998.
Borrowings under the line of credit will bear interest at bank prime less one
percent, payable monthly. At June 30, 1997, there were no borrowings under the
line of credit, however, HSOG has issued letters of credit in the amount of
$60,000 which is guaranteed by this line. HSOG pays a commitment fee of one-half
of one percent ( 1/2%) per annum on the unused portion of the line.

     In 1996, HSOG aggressively applied cash flows to the retirement of its bank
loans. Payments of principal on the loans were $1,825,783, which was $456,463
over the required amount. HSOG has continued this policy in 1997 by paying
$912,880 in excess of the required monthly payments through June 30, 1997. HSOG
anticipates that the due date of this note will be extended into 1999. Based on
the outstanding balance at June 30, 1997, and assuming no additional payments in
excess of the required monthly payments, the bank loan will be fully retired on
April 30, 1999.

     In connection with HSOG's bank loans and credit facility, there are certain
covenants which require, among other things, that HSOG maintain (i) a ratio of
cash flow (defined in the loan agreement to be income before income taxes plus
all depreciation, depletion and amortization and condemned and abandoned
property expense) to current maturities of long-term debt of more than 1.4 to
1.0, (ii) a ratio of total liabilities to stockholders' equity of not more than
1.4 to 1.0, and (iii) a minimum net worth of not less than $6,000,000. In
addition, HSOG's annual cash dividends are limited to the lesser of $365,000 or
net income. No waiver by the bank will be required under the terms of HSOG's
bank loan in order to consummate the Merger.

     In 1996, HSOG's average direct operating costs per barrel of oil equivalent
increased 51% to $9.31. This increase is primarily due to non-recurring costs
incurred in the settlement of claims by surface owners 


                                     -48-
<PAGE>
 
and the remediation of saltwater contamination on a property in which HSOG owns
a 9% working interest. Excluding this property, the average direct operating
costs per barrel of oil equivalent for HSOG was $7.19. In December 1996 and
March 1997, HSOG sold several marginal properties that incurred high operating
costs; also excluding these properties, direct operating costs per barrel of oil
equivalent would have been $6.69.

     Average direct operating costs per barrel of oil equivalent are dependent
upon several factors, including principally the nature of a company's
operations. For example, gas properties are generally more economical to operate
than oil properties. Likewise, oil wells in a form of primary recovery (flowing
or pumping) are more economical to operate than oil wells in a form of secondary
recovery, such as waterfloods. HSOG has large interests in three waterflood or
water-drive operations. These properties contributed approximately 46% of the
total working interest barrels of oil equivalent production in 1996, but were
responsible for approximately 74% of the direct operating costs. Excluding these
waterflood properties, HSOG's direct operating costs per barrel of oil
equivalent in 1996 was $4.52.

     HSOG believes it will fully realize its deferred tax assets and,
accordingly, no valuation allowances have been provided. In management's
opinion, the deferred tax assets will be realized as reductions in future income
taxes payable or by utilizing available tax planning strategies. Uncertainties
that may affect the ultimate realization of these assets include future product
prices, costs and tax rates. Therefore, HSOG will periodically review these
factors and determine whether a valuation allowance has become necessary.

     Upon consummation of the Merger, it is likely that HSOG's effective tax
rate will increase as a result of the anticipated increase in income resulting
from the combined operations of HSOG and HSRC and the loss of HSRC's statutory
depletion deduction for federal income tax purposes. The exact annual income tax
effect of the lost depletion deduction is difficult to quantify due to the
complexities of the Code related to statutory depletion and the interaction of
this deduction and other provisions of the Code, such as the alternative minimum
tax. See "Risk Factors--Effects of the Merger" and "The Merger--Depletion
Deductions."

Inflation

     In recent years inflation has not had a significant impact on HSOG's
operations or financial conditions. The general economic pressures limiting oil
and gas prices in recent years have generally been accompanied by corresponding
downward pressure on costs to develop and operate oil and gas properties as well
as the costs of drilling and completing wells. The impact of inflation on HSOG
in the future will depend on the relative increases, if any, in the selling
price of oil and gas and in HSOG's operating, development and drilling costs.

Management's Discussion and Analysis of Financial Condition
and Results of Operations of HSRC

     The following discussion should be read in conjunction with HSRC's
financial statements and notes thereto included elsewhere herein.

Results of Operations

     Six Months Ended June 30, 1997 Compared to Six Months Ended June 30, 1996

     Net income for the first six months increased $326,868 from $764,270 in
1996 to $1,091,138 in 1997. The principal reasons for this increase are as
follows:

     Oil sales decreased $3,998 as a result of a decrease in production volumes
of 6,859 barrels, partially offset by an increase in the average price of oil
from $18.96 per barrel in 1996 to $20.06 per barrel in 1997. The decrease in
production volumes was primarily a result of property dispositions during 1996
and early 1997.


                                     -49-
<PAGE>
 
     Gas sales increased $332,422 (28%) due to an increase in the average gas
price per Mcf from $1.94 in 1996 to $2.44 in 1997, coupled with an increase in
production volumes from 614,133 Mcf in 1996 to 624,695 Mcf in 1997.

     Lease rentals and bonuses increased $38,026 due to higher leasing activity
in 1997 than in 1996.

     Interest income decreased $11,632 from 1996, which included a $11,400
discount related to the prepayment of certain production taxes in the state of
Montana.

     Gain on sales of assets increased $96,940 in 1997 following HSRC's sale of
its interest in the N.E. Alden Field. There were no comparable sales in 1996.

     Income from equity affiliates increased $136,426 in 1997. HSRC's principal
equity investee, HSOG, reported net income of $941,663 in 1997 and $509,661 in
the same period of 1996. In addition, HSRC's ownership in HSOG increased from
31.7% to 33.9% in November 1996.

     Lease operating expenses decreased $258,137 (25%) from 1996. This decrease
is principally attributable to environmental remediation expenses in 1996
associated with a waterflood property in which HSRC has a 9% working interest,
coupled with an insurance reimbursement in 1997 of certain of such costs of
approximately $145,250

     Dry hole costs increased $324,327 in 1997 due to a greater incidence of dry
holes. In 1996 there were 3 dry holes (.18 net) drilled at an average gross cost
of $257,900 per well; in 1997 there were 6 dry holes (.86 net) drilled at an
average gross cost of $431,100 per well.

     Condemned and abandoned property expense increased $51,596. 1996 expense
was a net credit of $5,081, primarily the result of salvage credits of $12,488
received on a property abandoned during the first quarter. 1997 expense was also
higher due to the abandonment of acreage costs associated with six dry holes in
1997, compared to two in 1996.

     General and administrative expense increased $71,303 (15%). This increase
is primarily associated with the addition of certain full-time and contract
employees in late 1996 and early 1997. Such personnel were added in anticipation
of an increase in HSRC's exploration activities.

Interest expense decreased $99,611 in 1997, reflecting HSRC's lower average
borrowings.

     Year ended December 31, 1996 Compared to Year Ended December 31, 1995

     Net income for 1996 increased 197% from $620,835 in 1995 to $1,844,161 in
1996. The factors contributing to this increase are as follows:

     Oil sales increased $1,117,808 (30%) primarily as a result of an increase
in the average sales price per barrel from $16.15 in 1995 to $20.16 in 1996,
coupled with an increase in production of 9,799 barrels. The increase in
production was contributed by producing properties HSOG acquired in 1995 and
1996, along with new drilling in 1996.

     Gas sales increased 37% ($678,099) as a result of an increase in the
average sales price from $1.41 per Mcf in 1995 to $2.02 per Mcf in 1996,
partially offset by a 4% decrease in production.

     Interest income increased $12,488 primarily as a result of more excess
funds available for investment.

     Gains on sales of assets increased 152% ($101,628) in 1996. HSRC had two
major property sales in 1996. In November, HSRC sold its interest in a
Montgomery County, Texas field at a gain of $140,730. In December, HSRC sold its
interest in 60 small, marginal properties at a small gain.

incurred high operating costs. The properties sold incurred lease operating
expenses in 1996 of $233,039.

     Production taxes increased 31% ($149,602) as a result of the higher oil and
gas sales described above.

     Dry hole costs decreased 25% ($44,686) in 1996. In 1996 there were 5 dry
holes drilled (.45 net) at an average cost of $293,300 per net well; in 1995
there were 5 dry holes (.63 net) drilled at an average cost of $280,400 per net
well.

     Condemned and abandoned property expense decreased $26,775 (32%). 1996
expense includes salvage credits of $12,488 received on a property abandoned
during the first quarter. 1995 expense was unusually high due to the non-
recurring abandonment of acreage costs associated with three dry holes, coupled
with the expiration of leases on certain non-producing acreage owned by HSRC.

     General and administrative expense decreased $275,566 (26%) in 1996.
General and administrative expense incurred in 1995 included approximately

This amount was received in settlement of a suit HSRC and HSOG brought against
the carrier for recovery of certain costs incurred by HSRC in the successful
defense of HSRC's directors in a lawsuit commenced in 1991.

     Interest expense decreased 21% ($66,222) due to the decreases in HSRC's

such activities through June 30, 1997, and has commitments of approximately $1.5
million for the remainder of 1997 and into 1998.

     HSRC's working capital at June 30, 1997, was approximately $794,000
compared to a working capital deficit of approximately $218,000 at December 31,
1996. During 1996 and the first two quarters of 1997,

                                     -51-

HSRC aggressively applied cash flows to the retirement of its bank loans. As a
result, HSRC fully retired its outstanding bank loans on May 31, 1997.

     HSRC maintains a revolving line of credit with a bank in the amount of
$700,000 which expires May 1, 1998. Borrowings under the line of credit bear
interest at bank prime less one percent, payable monthly. There were no
outstanding borrowings under the line of credit at June 30, 1997, however, HSRC
has issued a letter of credit in the amount of $60,000 which is guaranteed by
this line. HSRC pays a commitment fee of one-half of one percent ( 1/2%) per
annum on the unused portion of the line.

     Product prices for oil and natural gas have decreased approximately 20% and
45%, respectively, since the beginning of 1997. Despite the price reductions,
HSRC expects to finance its anticipated 1997 operations and budgeted exploration
and development activities from cash flows from operations.

     In connection with HSRC's credit facility, there are certain covenants
which require, among other things, that HSRC maintain (i) a ratio of cash flow
(defined in the loan agreement to be income before income taxes plus all
depreciation, depletion and amortization and condemned and abandoned property
expense) to current maturities of long-term debt of more than 1.5 to 1.0, (ii) a
ratio of total liabilities to stockholders' equity of not more than 1.0 to 1.0,
and (iii) a minimum net worth of not less than $9,000,000. In addition, HSRC's
annual cash dividends are limited to the lesser of $425,000 or net income.

     In 1996, HSRC's average direct operating costs per barrel of oil equivalent
increased 47% to $9.03. This increase is primarily due to non-recurring costs
incurred in the settlement of claims by surface owners and the remediation of
saltwater contamination on a property in which HSRC owns a 9% working interest.
Excluding this property, the average direct operating costs per barrel of oil
equivalent for HSRC was $6.93. In December 1996 and March 1997, HSRC sold, at a
gain, several marginal properties that incurred high operating costs; also
excluding these properties, direct operating costs per barrel of oil equivalent
would have been $6.42.

     Average direct operating costs per barrel of oil equivalent are dependent
upon several factors, including principally the nature of a company's
operations. For example, gas properties are generally more economical to operate
than oil properties. Likewise, oil wells in a form of primary recovery (flowing
or pumping) are more economical to operate than oil wells in a form of secondary
recovery, such as waterfloods. HSRC has large interests in three waterflood or
water-drive operations. These properties contributed approximately 46% of the
total working interest barrels of oil equivalent production in 1996, but were
responsible for approximately 74% of the direct operating costs. Excluding these
waterflood properties, HSRC's direct operating costs per barrel of oil
equivalent in 1996 was $4.52.

     HSRC believes it will fully realize its deferred tax assets and,
accordingly, no valuation allowances have been provided. In management's
opinion, the deferred tax assets will be realized as reductions in future income
taxes payable or by utilizing available tax planning strategies. Uncertainties
that may affect the ultimate realization of these assets include future product
prices, costs and tax rates. Therefore, HSRC will periodically review these
factors and determine whether a valuation allowance has become necessary.

Inflation

     In recent years inflation has not had a significant impact on HSRC's
operations or financial conditions. The general economic pressures limiting oil
and gas prices in recent years have generally been accompanied by corresponding
downward pressure on costs to develop and operate oil and gas properties as well
as the costs of drilling and completing wells. The impact of inflation on HSRC
in the future will depend on the relative increases, if any, in the selling
price of oil and gas and in HSRC's operating, development and drilling costs.

            DESCRIPTION OF THE BUSINESS OF THE HOME-STAKE COMPANIES

General

     HSOG and HSRC (referred to together herein as "The Home-Stake Companies")
are actively engaged in the acquisition, exploration, development and production
of oil and gas properties. Their principal geographic operating areas lie within
the states of Oklahoma, Montana, Wyoming, Louisiana, Texas and New Mexico.

     HSOG and HSRC were incorporated in the State of Oklahoma in 1917 and 1929,
respectively. Since its incorporation, HSRC has been under common management
with HSOG. The Home-Stake Companies' principal business activity from the dates
of their incorporation through the early 1950's was the acquisition and leasing
of oil and gas mineral interests. Accordingly, The Home-Stake Companies'
revenues were primarily from their royalty interests in oil and gas production
and from the mineral interests in properties leased to others. Beginning in the
1950's, The Home-Stake Companies began to actively participate as working
interest partners primarily in wells being drilled by other industry partners.
The Home-Stake Companies also originated and participated in the drilling of a
few of their own prospects and discovered several significant oil fields in
south central Kansas.

     Since the latter part of the 1950's, HSOG has participated in the
acquisition and drilling of oil and gas properties jointly with HSRC. Since that
time, The Home-Stake Companies have operated in most respects as a single
entity. The Home-Stake Companies jointly participate in the acquisition of
mineral and leasehold interests and in exploration and development activities
performed on jointly owned properties. Each company generally owns equal
interests in the oil and gas properties, however such interests do vary.
Effective January 1, 1996, the participation arrangement between the companies
was changed such that HSOG's participation interest in property acquisitions,
new drilling ventures and other investments is 40% (it was previously 50%) and
HSRC's participation interest therein is 60%. Only HSRC serves as operator of
certain producing properties owned by The Home-Stake Companies (although,
because general and administrative costs incurred are shared equally by HSOG and
HSRC, HSOG is allocated 50% of the operating fee revenues received by HSRC).
HSRC currently operates 52 producing wells.

     In the mid-1970's, The Home-Stake Companies revised their business
strategies to pursue programs to increase their revenues generated from the
ownership of working interests in oil and gas properties relative to their
revenues generated from royalty interests (resulting from the ownership and
leasing of oil and gas mineral interests). The Home-Stake Companies increased
their relative investments in drilling ventures developed and sold by other
industry partners and in the oil and gas properties that they acquired. In 1977,
HSOG and HSRC received approximately 70% and 75% of their respective revenues
from royalty interests; whereas, in 1996, approximately 26% and 27% of their
respective revenues were from royalty interests.

     At December 31, 1996, HSOG had estimated proved reserves of 8,501,078 Mcf
of natural gas and 2,383,955 barrels of oil, and HSRC had estimated proved
reserves of 8,835,929 Mcf of natural gas and 2,432,711 barrels of oil. Natural
gas reserves constituted approximately 37% of HSOG's reserves and 38% of HSRC's
reserves based on an "oil equivalent" basis (converting each six Mcf of natural
gas to a barrel of oil, representing the estimated relative energy content of
oil and natural gas).

Partnerships

     The Home-Stake Companies serve as general partners of H-S Royalty, Ltd., an
Oklahoma limited partnership (the "Partnership"), formed in 1982. The
Partnership was formed by The Home-Stake Companies for the purpose of
distributing to their stockholders a 3/16th royalty interest in certain jointly
owned mineral interests in properties, which were nonproducing at the time of
the formation of the Partnership, located in ten states. In addition, the
Partnership was formed to allow the stockholders of The Home-Stake Companies to
realize a portion of the direct economic benefits that result from the
commercial production and sale of oil and gas, as well as the maximization of
certain income tax benefits attributable to oil and gas producing activities. 


                                     -53-
<PAGE>
 
In connection with the administration of the Partnership, each of The Home-Stake
Companies receives a monthly administrative management fee of $250. If the
Merger is consummated, HSOG will serve as sole general partner and receive a
monthly administrative management fee of $500.

Competition

     The business of acquiring and developing desirable oil and gas properties
is highly competitive. In seeking to obtain desirable producing properties, new
leases and exploration prospects, The Home-Stake Companies face competition from
both major and independent oil and gas companies, as well as from numerous
individuals and income and drilling programs. Many of these competitors have
financial and other resources substantially in excess of those available to The
Home-Stake Companies.

     There is also extensive competition in locating markets for gas produced by
The Home-Stake Companies. Increases in worldwide energy production capability
and decreases in energy consumption as a result of conservation efforts have
brought about substantial surpluses in energy supplies in recent years. This, in
turn, has resulted in substantial competition for markets historically served by
domestic natural gas sources both with alternate sources of energy, such as
residual fuel oil, and among domestic gas suppliers. As a result, there have
been reductions in oil prices, widespread curtailment of gas productions and
delays in producing and marketing gas after it is discovered. Changes in
government regulations relating to the production, transportation and marketing
of natural gas have also resulted in significant changes in the historical
marketing patterns of the industry. Generally, these changes have resulted in
the abandonment by many pipelines of long-term contracts for the purchase of
natural gas, the development by gas producers of their own marketing programs to
take advantage of new regulations requiring pipelines to transport gas for
regulated fees, and an increasing tendency to rely on short-term sales contracts
priced at spot market prices.


     In light of these developments, many producers, including The Home-Stake
Companies, have accepted oil prices that are lower than those previously
prevailing in order to sell their production. Also, gas prices, which were once
effectively determined by government regulations, are now influenced largely by
the effects of competition. Competitors in this market include other producers,
gas pipelines and their affiliated marketing companies, independent marketers,
and providers of alternate energy supplies, such as residual fuel oil.

Marketing

     The Home-Stake Companies' gas production from properties in which they own
working interests is sold primarily on the spot market with a variety of
purchasers, including intrastate and interstate pipeline companies, their
marketing affiliates, independent marketing companies and other companies who
have the ability to move gas under firm transportation agreements. Gas produced
from properties in which The Home-Stake Companies own royalty interests is
marketed and sold by owners of the leasehold interests in such properties.

     Substantially all of The Home-Stake Companies' crude oil and condensate
production is sold at posted prices under short-term contracts, as is customary
in the industry.

Seasonality

     The results of operations of The Home-Stake Companies are subject to
seasonal fluctuations in the price for natural gas. Natural gas prices have been
generally higher in the fourth and first quarters. Due to these seasonal
fluctuations, results of operations for individual quarterly periods may not be
indicative of results which may be realized on an annual basis.


                                     -54-

Regulation

     General

     The oil and gas industry is extensively regulated by federal, state and
local authorities. Legislation affecting the oil and gas industry is under
constant review for amendment or expansion. Numerous departments and agencies,
both federal and state, have issued rules and regulations binding on the oil and
gas industry and its individual members, some of which carry substantial
penalties for the failure to comply. The regulatory burden on the oil and gas
industry increases its cost of doing business and, consequently, affects its
profitability. Inasmuch as such laws and regulations are frequently amended or
reinterpreted, The Home-Stake Companies are unable to predict the future cost or
impact of complying with such regulations.


     Exploration and Production

     Exploration and production operations of The Home-Stake Companies are
subject to various types of regulation at the federal, state and local levels.
Such regulation includes requiring permits for the drilling of wells,
maintaining bonding requirements in order to drill or operate wells, and
regulating the location of wells, the method of drilling and casing wells, the
surface use and restoration of properties upon which wells are drilled and the
plugging and abandoning of wells. The Home-Stake Companies' operations are also
subject to various conservation matters. These include the regulation of the
size of drilling and spacing units or proration units and the density of wells
which may be drilled and the unitization or pooling of oil and gas properties.
In this regard, some states allow the forced pooling or integration of tracts to
facilitate exploration while other states rely on voluntary pooling of lands and
leases. State conservation laws also establish maximum rates of production from
oil and gas wells, generally prohibit the venting or flaring of gas and impose
certain requirements regarding the ratability of production. In addition, Texas
and Oklahoma have adopted laws and regulations placing limits on gas production
that attempt to match production with market demand. The effect of these laws
and regulations is to limit the amounts of oil and gas The Home-Stake Companies
can produce from their wells, and to limit the number of wells or the locations
at which The Home-Stake Companies can drill.

     Sales and Transportation

     Federal legislation and regulatory controls have historically affected the
price of the gas produced by The Home-Stake Companies and the manner in which
such production is marketed. However, due to the deregulation provisions of the
Natural Gas Policy Act of 1978, the Natural Gas Wellhead Decontrol Act of 1989
and regulations promulgated by the Federal Energy Regulatory Commission
("FERC"), the price of virtually all gas produced by producers not affiliated
with interstate pipelines has been deregulated. As a result, most of The Home-
Stake Companies' gas production is no longer subject to price regulation. Gas
which has been removed from price regulation is subject only to that price
contractually agreed upon between the producer and purchaser. Market determined
prices for deregulated natural gas fluctuate in response to market pressures.

     The FERC regulates interstate natural gas transportation rates and service
conditions, which affects the marketing of gas produced by The Home-Stake
Companies, as well as the revenues received from sales of such production. Since
the mid-1980s, the FERC has issued a series of orders, culminating in Order Nos.
636, 636-A and 636-B ("Order 636"), that have significantly altered the
marketing and transportation of gas. Order 636 mandates a fundamental
restructuring of interstate pipelines sales and transportation service,
including the unbundling by interstate pipelines of the sales, transportation,
storage and other components of the city-gate sales services such pipelines
previously performed. One of the FERC's purposes in issuing the orders is to
increase competition within all phases of the gas industry. Order 636 and
subsequent FERC orders on rehearing have been appealed and are pending judicial
review. Because the orders may be modified as a result of the appeals, it is
difficult to predict the ultimate impact of the orders on The Home-Stake
Companies and their gas marketing efforts. Generally, Order 636 has eliminated
or substantially reduced the interstate pipelines' traditional role as
wholesalers of natural gas and has substantially increased competition and
volatility in natural gas markets. While significant regulatory uncertainty
remains, Order 636 may ultimately enhance the ability of producers such as The
Home-Stake Companies to market and transport 

                                      -55-
<PAGE>
 
their gas directly to end-users and local distribution companies, although it
may also subject producers to greater competition and the more restrictive
pipeline imbalance tolerances and greater associated penalties for violation of
such tolerances.

     Sales of oil and natural gas liquids by The Home-Stake Companies are not
regulated and are made at market prices. The price The Home-Stake Companies
receive from the sale of these products is affected by the cost of transporting
the products to market. Effective as of January 1, 1995, the FERC implemented
regulations establishing an indexing system for transportation rates for oil
pipelines, which, generally, would index such rates to inflation, subject to
certain conditions and limitations. These regulations could increase the cost of
transporting oil and natural gas liquids by pipeline, although the most recent
adjustment generally decreased rates. These regulations are subject to pending
petitions for judicial review. The Home-Stake Companies are not able to predict
with certainty what effect, if any, these regulations will have on their
operations, however, the regulations may, over time, tend to increase
transportation costs or reduce wellhead prices for oil and natural gas liquids.

     Operational Hazards and Insurance

     The operations of The Home-Stake Companies are subject to all risks
inherent in the exploration for, and development and production of, oil and
natural gas, including such natural hazards as blowouts, cratering and fires,
which could result in damage or injury to, or destruction of, drilling rigs and
equipment, formations, producing facilities or other property, or could result
in personal injury, loss of life or pollution of the environment. Any such event
could result in substantial cost to The Home-Stake Companies which could have a
material adverse effect upon the financial condition of each of The Home-Stake
Companies to the extent it is not fully insured against such risk. Each of HSOG
and HSRC carries insurance against certain of these risks but, in accordance
with standard industry practice, is not fully insured for all risks, either
because such insurance is unavailable or because it elects not to obtain
insurance coverage because of cost. Although such operational risks and hazards
may to some extent be minimized, no combination of experience, knowledge and
scientific evaluation can eliminate the risk of investment or assure a profit to
any company engaged in oil and gas operations.

Environmental Matters

     Operations of The Home-Stake Companies are subject to numerous and
constantly changing federal, state and local laws and regulations governing the
discharge of materials into the environment or otherwise relating to
environmental protection. These laws and regulations may require the acquisition
of certain permits, restrict or prohibit the types, quantities and concentration
of substances that can be released into the environment in connection with
drilling and production, restrict or prohibit drilling activities that could
impact wetlands, endangered or threatened species or other protected natural
resources and impose substantial liabilities for pollution resulting from The
Home-Stake Companies' operations. Such laws and regulations may substantially
increase the cost of exploring for, developing or producing oil and gas and may
prevent or delay the commencement or continuation of a given project. In the
opinion of The Home-Stake Companies' management, The Home-Stake Companies are in
substantial compliance with current applicable environmental laws and
regulations and it is not anticipated that The Home-Stake Companies will be
required in the near future to expend amounts that are material in the aggregate
to their overall operations by reason of environmental laws and regulations.
Nevertheless, changes in existing environmental laws and regulations or in the
interpretations thereof could have a significant impact on the operating costs
of The Home-Stake Companies, as well as the oil and gas industry in general. For
instance, legislation has been proposed in Congress from time to time that would
reclassify certain oil and gas production wastes as "hazardous wastes," which
reclassification would make exploration and production wastes subject to much
more stringent and costly handling, disposal and clean-up requirements. State
initiatives to further regulate the disposal of oil and gas wastes and naturally
occurring radioactive materials are also pending in certain states and these
various initiatives could have a similar impact on The Home-Stake Companies.

     The Comprehensive Environmental Response, Compensation, and Liability Act
("CERCLA"), also known as the "Superfund" law, imposes liability, without regard
to fault or the legality of the original conduct, on certain classes of persons
that are considered to have contributed to the release of a "hazardous
substance" into the environment. These persons include the owner or operator of
the disposal site or the site

                                      -56-
<PAGE>
 
where the release occurred and companies that disposed or arranged for the
disposal of the hazardous substances found at the site. Persons who are or were
responsible for releases of hazardous substances found at the site and persons
who are or were responsible for releases of hazardous substances under CERCLA
may be subject to joint and several liability for the costs of cleaning up the
hazardous substances that have been released into the environment and for
damages to natural resources, and it is not uncommon for neighboring landowners
and other third parties to file claims for personal injury and property damage
allegedly caused by the hazardous substances released into the environment. The
Home-Stake Companies are only able to directly control the operation of those
wells with respect to which HSRC acts as operator. Notwithstanding The Home-
Stake Companies' lack of control over wells operated by others, the failure of
an operator of a well in which The Home-Stake Companies own a working interest
to comply with applicable environmental regulations may, in certain
circumstances, be attributed to The Home-Stake Companies. As of the date of this
Proxy Statement/Prospectus, The Home-Stake Companies have no material
commitments for capital expenditures to comply with existing environmental
requirements.

Properties of The Home-Stake Companies

     HSOG owns interests in 1,363 producing properties, including both non-
operated working interests and royalty interests, located in 16 states, and HSRC
owns interests in 1,442 producing properties, including both operated and non-
operated working interests and royalty interests, located in 16 states. (For
further details regarding these properties see "--Producing Wells" below.) Each
of The Home-Stake Companies is engaged in leasing of its minerals as well as the
exploration, production and sale of natural gas, condensate and crude oil from
its properties.

     Each of The Home-Stake Companies has an extensive ownership of nonproducing
perpetual minerals located in 16 states, including North Dakota, Oklahoma,
Michigan, Montana, Mississippi and Texas. Such ownership at June 30, 1997,
comprises 3,037 properties covering 40,329 net acres with respect to HSOG and
3,204 properties covering 52,805 net acres with respect to HSRC. The Home-Stake
Companies may from time-to-time participate in exploration activities on certain
of their respective properties but generally lease them to others, retaining a
royalty interest in whatever production may be derived therefrom, thereby
eliminating the risk in the exploration of such properties. At the present time,
there are approximately 45 (829 net acres) and 50 (1,152 net acres) properties
leased to others by HSOG and HSRC, respectively.

     In addition, HSOG and HSRC own leasehold interests in 121 (2,544 net acres)
and 121 (2,672) net acres) nonproducing properties, respectively. These
properties have varying lease terms, with most expiring in the next five years.
These leasehold interests are located in eleven states, including Oklahoma and
Montana.

     Current Activities

     The Home-Stake Companies' exploration and development activities generally
have been located in the states of Oklahoma (Anadarko Basin), Montana and Texas.
In 1996, the majority of The Home-Stake Companies' activities were located in
Gaines County, Texas, as well as Comanche and Caddo Counties, Oklahoma. Most
recent drilling has been developmental in nature (85% in 1996 and 88% in 1995)
on both oil and gas properties. In 1996, there were 5 oil wells and 14 gas wells
drilled; in 1995 there were 3 oil wells and 15 gas wells drilled.

     The Home-Stake Companies' drilling activities in 1997 continue to be
primarily developmental in nature. Through June 30, 1997, there have been 11
(1.21 net) development wells and 3 (.75 net) exploratory wells drilled,
resulting in 1 (.02 net) oil well, 7 (.46 net) gas wells and 6 (1.48 net) dry
holes. The Home-Stake Companies are presently committed to participate in the
drilling or completion of 17 (1.07 net to HSOG and 1.32 net to HSRC) wells in
1997. HSRC expects to operate seven of these wells. In 1997, The Home-Stake
Companies contracted with three consulting geologists for the right of first
refusal on developmental prospects the consultants are developing in the Permian
Basin and South Central Oklahoma. The primary area of focus during the next 12
to 18 months will be developmental drilling on The Home-Stake Companies'
Oklahoma acreage and in the Permian Basin. In addition, The Home-Stake Companies
plan to continue to pursue exploratory oil and gas prospects in the Anadarko and
Arkoma Basins in Oklahoma.

                                      -57-
<PAGE>
 
     The Home-Stake Companies are active in the property acquisition market. In
1996, The Home-Stake Companies reviewed 68 property sales packages and submitted
bids on four of these packages, containing eight groups of properties. They were
successful in acquiring one group of properties. Through July 31, 1997, The 
Home-Stake Companies have reviewed over 30 sales packages.

     During 1995, HSOG and HSRC each acquired approximately 220 net acres of
leases in the Lodgepole "play" in North Dakota at a cost of $85,000 to each
company. The Lodgepole area is generating a great deal of interest in the oil
and gas industry and it is expected that new drilling will commence in this
area. In February 1996, The Home-Stake Companies executed permits to allow 3-D
seismic work on certain of these leases. There are no present plans by The Home-
Stake Companies to initiate exploration in this area in the near future;
however, it is the intention of each company to participate with its leased
acreage in wells proposed by others.

Drilling Activity

     During the periods indicated, HSOG and HSRC drilled or participated in the
drilling of the following exploratory and development wells:

     The above well information excludes wells in which either or both of The
Home-Stake Companies own only a royalty or mineral interest.

     At December 31, 1996, The Home-Stake Companies were participating in the
drilling of six (.62 net) development wells. As of the date of this Proxy
Statement/Prospectus, two wells (.49 net) were determined to be non-productive
and four (.13 net) were successfully completed as producing gas wells.

HSRC Operating Activities

     As noted previously, only HSRC serves as operator of oil and gas properties
in which The Home-Stake Companies have operations. HSRC operates 52 producing
wells and 7 service wells located in 10 separate fields, which includes 2
waterfloods consisting of 9 producing wells and 3 service wells. In addition,
each of HSOG and HSRC have non-operating working interest ownership in
approximately 254 other properties.

     HSRC operates wells in two fields in Dawson County, Montana--the Glendive
Field and the Gas City Field. The operations in the Glendive Field consist of 15
producing wells and four saltwater disposal wells. The Gas City Field is
unitized for secondary recovery operations and consists of nine producing wells
and three water injection wells. Production is primarily from the Red River
formation of Ordovician age in both of these fields.

     Operations in the Golden Trend Field in Grady and McClain counties in
Oklahoma consist of 16 producing wells completed in four formations of
Pennsylvanian and Ordovician age rock.

     Northwestern Oklahoma operations consist of five producing wells in the
Vici Field in Ellis County. Production is from Pennsylvanian age rock.

     HSRC operates a producing field in the West Cement Field in Caddo County,
Oklahoma. At present, there is one producing well completed in the Medrano
formation of Pennsylvania age rock.

     Operations in the Anadarko Basin of Eastern Oklahoma consist of five
producing gas wells located in the Hartshorne South and Kinta Fields in Latimer
County and the Ti North and Ashland Fields in Pittsburg County.

     HSRC also operates one well in the Champmon Strawn Field in Gaines County,
Texas.

Producing Wells

     The following table sets forth certain information relating to HSOG's and
HSRC's producing wells at December 31, 1996. The table also sets forth
information relating to the producing wells on a pro forma pooled basis assuming
consummation of the Merger as of December 31, 1996. Because each of HSOG and
HSRC owns the mineral interests in numerous producing properties, it does not
have current information on the numbers of wells drilled by the owners of the
leasehold interests for these properties. Accordingly, HSOG and HSRC keep track
of their respective royalty interests on a property-by-property basis rather
than well-by-well basis. Net wells refers to the total number of wells in which
HSOG or HSRC, as appropriate, has an interest, multiplied by HSOG's or HSRC's,
as appropriate, working interest percentage in the wells.

/(1)/  The term "net wells" is not applicable to a royalty interest since
       neither HSOG nor HSRC has a working interest in the applicable well.

Acreage

     As previously noted, at December 31, 1996, HSOG owned an interest in 1,363,
producing properties, including royalty interests on 1,056 properties
(comprising approximately 11,837 net acres) and working interests in 307
properties (comprising 6,945 net acres); and HSRC owned an interest in 1,442
producing properties, including royalty interests on 1,136 properties
(comprising approximately 15,102 net acres) and working interests in 306
properties (comprising 7,278 net acres). The following table sets forth gross
and net oil and gas leasehold acreage for HSOG, HSRC and HSOG on a pro forma
basis (assuming consummation of the Merger) as of December 31, 1996.

Proved Reserves

     The following tables reflect the estimated proved reserves and proved
developed producing reserves, future net revenues and the present value of
future net revenues from such reserves of HSOG and HSRC at June 30, 1997, as
prepared by HSOG and HSRC. The reserve estimates with respect to certain of
HSOG's and HSRC's properties, covering approximately 75% and 71% of the present
value of future net revenues from the proved reserves of HSOG and HSRC,
respectively, at June 30, 1997, were reviewed by Lee Keeling and Associates,
Inc. The quantities of HSOG's or HSRC's, as appropriate, proved reserves of oil
and natural gas presented below include only those amounts which HSOG or HSRC
reasonably expects to recover in the future from known oil and gas reservoirs
under existing economic and operating conditions. Proved developed producing
reserves are limited to those quantities which are recoverable commercially at
current prices and costs, under existing regulatory practices and with existing
technology. Accordingly, any changes in prices, operating and developmental
costs, regulations, technology or other factors could significantly increase or
decrease estimates of HSOG's or HSRC's proved developed producing reserves.
HSOG's or HSRC's, as appropriate, proved undeveloped reserves (which are
included in proved reserves) include only those quantities which HSOG or HSRC
reasonably expects to recover from the drilling of new wells based on geological
evidence from directly offsetting wells. The risks of recovering these reserves
are higher from both geological and mechanical perspectives than the risks of
recovering developed reserves. The estimates of HSOG's and HSRC's proved
reserves do not include proved undeveloped reserves attributable to HSOG's or
HSRC's royalty interests (this information is not available to HSOG or HSRC) or
outside operated working interests (quantities are not considered material to
either HSOG's or HSRC's proved reserves). Furthermore, the reserve estimates do
not include reserves whose estimates of recoverability are less precise,
commonly referred to as "probable" or "possible" reserves. Neither HSOG nor HSRC
has reserves outside the continental United States.

       /(2)/     The difference between present value of future net revenues and
                 the standardized measure of discounted future net cash flows is
                 the present value of estimated income taxes applicable to
                 future net cash flows.

       The future net revenues are determined by using estimated quantities of
proved reserves and proved developed producing reserves and the periods in which
they are expected to be developed and produced based on economic conditions at
June 30, 1997. The estimated future revenues from production are based on the
actual prices in effect at June 30, 1997, except where fixed and determinable
price escalations are provided by contract. The resulting estimated future gross
revenues are reduced by estimated future costs to develop and produce the proved
reserves based on cost levels at June 30, 1997, but not for debt service,
general and administrative expense and income taxes. The present value of future
net revenues shown above should not be construed as the current market value, or
the market value as of June 30, 1997, of the estimated oil and gas reserves
attributable to HSOG's or HSRC's properties. For additional information
concerning the discounted future net revenues to be derived from these reserves
and the disclosure of the standardized measure information in accordance with
the provisions of Statement of Financial Accounting Standards No. 69, see
"Supplementary Information on Oil and Gas Producing Activities (unaudited)" at

       The reserve data set forth in this Proxy Statement/Prospectus represents
only estimates. Reserve engineering is a subjective process of estimating
underground accumulations of crude oil and natural gas that cannot be measured
in an exact manner. The accuracy of any reserve estimate is a function of the
quality of available data and of engineering and geological interpretation and
judgment. As a result, estimates of different engineers often vary. In addition,
results of drilling, testing and production subsequent to the date of an
estimate may justify revision of such estimate. Accordingly, reserve estimates
often differ from the quantities of crude oil and natural gas that are
ultimately recovered. The meaningfulness of such estimates is highly dependent
upon the accuracy of the assumptions upon which they were based.

Oil and Gas Production, Sales Prices and Production Costs

       The following table sets forth certain information regarding the
production of oil and natural gas, average sales prices and, for properties in
which the companies own a working interest, average production costs (including
production taxes and transportation charges) for HSOG, HSRC and pro forma HSOG
(assuming the consummation of the Merger as of January 1, 1995) for the periods
indicated.

Employees

     At June 30, 1997, HSOG employed 16 persons whose functions are associated
with management, operations and mineral management, engineering, geology, land
and gas contract administration, accounting and financial planning, and
administration and data processing. Each employee holds an identical position
with HSRC and is considered to spend one-half of his or her time on HSOG's
business and one-half of his or her time on HSRC's business. Accordingly, HSOG
pays one-half of the compensation to its employees and HSRC pays the other one-
half. Also at June 30, 1997, the Company had placed three consulting geologists
on retainer for 1997 to develop oil and gas prospects for the Company. The Home-
Stake Companies consider their relations with their employees to be excellent.

Litigation

     The Home-Stake Companies are involved in various lawsuits arising in the
ordinary course of business. While the outcome of any such lawsuits against The
Home-Stake Companies cannot be predicted with certainty, management does not
expect these matters to have a material effect on the financial position or the
results of operations of either HSOG or HSRC or of HSOG subsequent to the
Merger.

            AMENDMENTS TO THE CERTIFICATE OF INCORPORATION OF HSOG

     HSOG was incorporated in 1917 and the HSOG Certificate and Bylaws have been
amended many times over the years on a somewhat piecemeal basis in an attempt to
meet more modern corporate circumstances as they arise. In connection with its
review of the Merger, the HSOG Board also reviewed the current provisions of the
HSOG Certificate in an effort to determine whether any provisions should be
amended to better meet the needs of operating the surviving company after the
Merger as a larger single public company. Based on its review, the HSOG Board
has proposed the following amendments to the HSOG Certificate. The amendments to
the HSOG Certificate, if approved, will only become effective if the Merger is
consummated.

Dissenters' Rights

     In a 1992 decision, the Oklahoma Court of Appeals held that certain
dissenters' rights of shareholders of corporations formed under the Oklahoma
Business Corporation Act survived the 1986 enactment of the Oklahoma General
Corporation Act. See the discussion under "Proposed Amendment No. 8" below.
                                           ------------------------         
Under prior law, stockholders were provided dissenters' rights with respect to
any amendment to a corporation's certificate of incorporation (i) having an
adverse effect on a class of stockholders, (ii) reducing the number of directors
or (iii) changing or altering the corporate purposes. Accordingly, it is
possible that the proposed amendments to the HSOG Certificate create a right to
exercise dissenters' appraisal rights separate from those available with respect
to the Merger (see "The Merger--Appraisal Rights"). Decisions of the Oklahoma
Court of Appeals do not have a binding precedential effect and the Company
believes the decision is wrong and that no dissenters' rights exist with respect
to the proposed amendments to the HSOG Certificate. However, in order to assure
the validity of the adoption of the proposed amendments to the HSOG Certificate,
HSOG is providing dissenters' rights to its stockholders in connection with
these proposals. It is uncertain, if dissenters' rights under the Oklahoma
Business Corporation Act were found to survive the adoption of the Oklahoma
General Corporation Act, whether they should be exercised pursuant to the
Oklahoma Business Corporation Act or the Oklahoma General Corporation Act. In
this regard, HSOG will permit the exercise of dissenters' rights in connection
with the proposal amendments to the HSOG Certificate by compliance with either
Section 1091 of the Oklahoma General Corporation Act or Sections 1.159 and 1.160
of the repealed Oklahoma Business Corporation Act. A summary of the procedure to
exercise dissenters' appraisal rights under Section 1091 of the Oklahoma General
Corporation Act is set forth under "The Merger--Appraisal Rights" and Section
1091 is reprinted in its entirety as Appendix C to this Proxy
Statement/Prospectus. Sections 1.159 and 1.160 of the Oklahoma Business
Corporation Act which set forth the procedure for exercising dissenters' rights
under such act are set forth in their entirety as Appendix G to this Proxy
Statement/Prospectus.

                           Proposed Amendment No. 1
                           ------------------------

                            Proposal to Provide for
                         Perpetual Corporate Existence
                         (Item 2A on HSOG Proxy Card)

     The Board of Directors of HSOG has approved and recommends that the
stockholders of HSOG approve an amendment to the HSOG Certificate to provide
that HSOG shall have perpetual existence ("Proposed Amendment No. 1"). Article
Three of the HSOG Certificate limits the duration of HSOG's existence to March
12, 2007. Proposed Amendment No. 1 to Article Three of the HSOG Certificate
currently is set forth in Appendix E to this Proxy Statement/Prospectus.

     The predecessor of the Oklahoma General Corporation Act required
corporations to limit the duration of their existence in their certificates of
incorporation to no more than 50 years, subject to extension by the approval of
the stockholders. The Oklahoma General Corporation Act does not require a
corporation to limit its existence and, unless there is a provision limiting the
duration of a corporation to a specific date, the corporation has perpetual
existence. The Board of Directors of HSOG has determined that it is inefficient
to continue to require HSOG's stockholders to vote to extend the duration of
HSOG's existence.

                                      -65-
<PAGE>
 
     If Proposed Amendment No. 1 to the HSOG Certificate is approved by HSOG
stockholders, the approval of the holders of a majority of the outstanding
voting stock of HSOG prior to March 12, 2007 will not be necessary to extend the
duration of HSOG's existence past such date. Providing for perpetual existence
does not mean that the existence of HSOG may never be terminated and the
corporation dissolved. Under the Oklahoma General Corporation Act, HSOG may be
dissolved at any time upon (i) the adoption of a resolution by the Board of
Directors that HSOG should be dissolved and the approval of such resolution by
the holders of a majority of the outstanding voting stock of HSOG or (ii) by the
stockholders, without the action of directors, upon the written consent of the
holders of all the shares of outstanding voting stock of HSOG.

     Adoption of Proposed Amendment No. 1 will require the affirmative vote of
the holders of a majority of the outstanding shares of the HSOG Common Stock.
THE BOARD OF DIRECTORS OF HSOG RECOMMENDS THAT HSOG STOCKHOLDERS VOTE "FOR"
PROPOSED AMENDMENT NO. 1 TO THE HSOG CERTIFICATE.

                           Proposed Amendment No. 2
                           ------------------------

                            Proposal To Expand the
                           Business Purpose of HSOG
                         (Item 2B on HSOG Proxy Card)

     The Board of Directors of HSOG has approved and recommends that the
stockholders of HSOG approve an amendment to the HSOG Certificate to provide
that the purpose of HSOG is to engage in any lawful act or activity for which
corporations may be organized under the Oklahoma General Corporation Act
("Proposed Amendment No. 2"). The provisions of Article Four of the HSOG
Certificate currently limit the scope of the purpose and activities of HSOG to
the oil, gas and mineral business and related activities. Proposed Amendment No.
2 to Article Four is set forth in Appendix E to this Proxy Statement/Prospectus.

     The Oklahoma General Corporation Act provides that a corporation may set
forth in its certificate of incorporation that the purpose of the corporation is
to engage in any lawful act or activity for which corporations may be organized
under the general corporation law of Oklahoma and, by such statement, all lawful
acts and activities shall be within the purposes of the corporation. HSOG's
Board believes that business opportunities could arise from time to time outside
the oil and gas arena, in which event the limited purpose clause currently
contained in the HSOG Certificate would preclude HSOG's participation in such
opportunity even though it would be in the best interests of HSOG and its
stockholders. The Board believes the proposed amendment will provide HSOG with
more flexibility in pursuing any such opportunities should they arise. The HSOG
Board has no intention to engage in any business or activities other than the
oil and gas business at the present time.

     Adoption of Proposed Amendment No. 2 will require the affirmative vote of
the holders of a majority of the outstanding shares of HSOG Common Stock. THE
BOARD OF DIRECTORS OF HSOG RECOMMENDS THAT HSOG STOCKHOLDERS VOTE "FOR" PROPOSED
AMENDMENT NO. 2 TO THE HSOG CERTIFICATE.

                           Proposed Amendment No. 3
                           ------------------------

                       Proposal Concerning Establishment
                          of the Number of Directors
                         (Item 2C on HSOG Proxy Card)

     The Board of Directors of HSOG has approved and recommends that the
stockholders of HSOG approve an amendment to HSOG's Certificate to provide that
the Board shall consist of not less than three directors nor more than 15, the
exact number within such limits to be determined by a majority vote of the
directors ("Proposed Amendment No. 3"). In addition, Proposed Amendment No. 3
provides that until otherwise so determined by the directors, the Board of
Directors of HSOG shall consist of seven directors (which is the current number
of directors on HSOG's Board). To accomplish the proposed amendment, Article
Eight of the HSOG Certificate will be amended as set forth in Appendix E to this
Proxy Statement/Prospectus.

                                      -66-
<PAGE>
 
     The HSOG Certificate currently provides that there shall be seven
directors. Accordingly, in order to effect a change in the number of directors
it is necessary to amend the HSOG Certificate by obtaining approval of the
holders of a majority of HSOG's outstanding voting stock. The HSOG Board
believes the current provision setting forth the number of directors is too
inflexible and cumbersome in the event there should be a desired change in the
number of directors. The proposed amendment would allow the Board to add a
qualified candidate or candidates without first having to obtain stockholder
approval of an amendment to HSOG's Certificate. Any director added as a result
of Board action pursuant to the proposed amendment would still be subject to
election by the stockholders in order for such director to continue to serve as
such upon the expiration of his or her term (which term could be for a period of
three years due to the Board's classification into three classes with each class
serving staggered three-year terms). In addition, under the current HSOG
Certificate, should a vacancy occur in HSOG's Board and a qualified individual
could not be found on a timely basis, the HSOG Certificate may have to be
amended to reduce the number of directors. The HSOG Board believes the potential
risks of personal liability has made it more difficult for public companies to
find otherwise qualified individuals who are willing to accept a position as a
director. Also, the HSOG Board previously experienced difficulty in finding
qualified persons to fill Board vacancies because of an unwillingness of such
persons to serve as directors as a result of HSOG's pending litigation in
connection with prior attempts to gain control of HSOG and HSRC. Accordingly,
the HSOG Board deems it desirable to provide as much flexibility as possible
with respect to the number of directors and to avoid the cumbersome process of
having to amend the HSOG Certificate (which requires a vote of stockholders)
anytime there should be a desired change in the number of directors.

     Proposed Amendment No. 3 could be used by the HSOG Board as a measure to
deter or postpone an attempt to gain control of HSOG. HSOG's Bylaws provide for
the division of HSOG's Board into three classes, with members of each class
serving staggered three-year terms. Generally, two annual meetings of
stockholders, instead of one, would be required to effect a change in the
majority of the HSOG Board. In the event stockholders, or a stockholder who has
obtained control of HSOG through the acquisition of a substantial number of
shares of HSOG Common Stock or Preferred Stock, successfully elect a different
slate of directors than that supported by incumbent directors, the incumbent
directors, constituting a majority of directors, could, without stockholder
action, increase the number of directors and fill such positions with
individuals selected by the Board. Such action could possibly further postpone
changing the composition and control of HSOG's Board for an additional year. The
provisions of Proposed Amendment No. 3 could also have the effect of
discouraging a third party from initiating a proxy contest, making a tender
offer or otherwise attempting to gain control of HSOG even though such a
transaction could be beneficial to HSOG and its stockholders, although it should
be noted that holders of a majority of the shares of outstanding voting stock
could effect an amendment to HSOG's Certificate to eliminate the provisions of
the proposed amendment.

     Adoption of Proposed Amendment No. 3 will require the affirmative vote of
the holders of at least 66 2/3% of the outstanding shares of HSOG Common Stock.
THE BOARD OF DIRECTORS OF HSOG RECOMMENDS THAT HSOG STOCKHOLDERS VOTE "FOR"
PROPOSED AMENDMENT NO. 3 TO HSOG'S CERTIFICATE.

                           Proposed Amendment No. 4
                           ------------------------

            Proposal Eliminating Supermajority Vote for Approval of
           any Merger, Consolidation or Sale of Substantial Portion
            of Assets of HSOG or to Change the Number of Directors
                         (Item 2D on HSOG Proxy Card)

     The Board of Directors of HSOG has approved and recommends that the
stockholders of HSOG approve an amendment to the HSOG Certificate which would
eliminate the provisions of Article Nine of the HSOG Certificate requiring the
affirmative vote of holders of at least 66 2/3 percent of the outstanding shares
of HSOG's voting stock in order to approve and effect any merger, consolidation
or sale of a substantial portion of the assets of HSOG, or to change the number
of directors set forth in Article Eight of the HSOG Certificate. The provisions
of current Article Nine of the HSOG Certificate are set forth in Appendix E to
this Proxy Statement/Prospectus.

     Article Nine of the HSOG Certificate was first adopted by the stockholders
of HSOG primarily in response to an attempted hostile takeover attempt. The
provisions were intended to encourage any person or group who might seek to
acquire control of HSOG to negotiate with the Board as the Board's
recommendation of any such proposed 

                                      -67-
<PAGE>
 
transaction would likely be necessary in order to obtain the approval of HSOG
stockholders. By increasing the likelihood of Board participation in the
negotiations concerning any such transaction, the HSOG Board believed that the
short and long-term interests of HSOG's stockholders could best be safeguarded.
Article Nine of the HSOG Certificate was subsequently amended in 1994 to require
the approval of holders of at least 66 2/3 percent of HSOG's outstanding voting
stock to change the provisions for the number of directors set forth in the HSOG
Certificate in order to prevent any person or group seeking to gain control of
HSOG from obtaining control of the HSOG Board by amending the HSOG Certificate
upon obtaining the approval of HSOG stockholders only holding a majority of
HSOG's outstanding voting stock.

     In connection with its review of the proposed Merger, the HSOG Board
considered the benefits of the provisions of Article Nine against the
possibility that the public market might disfavor such supermajority voting
requirements and, thus, discount the value of the shares of New HSOG Common
Stock after the Merger. After such consideration, the HSOG Board determined that
the control shares provisions of the HSOG Certificate and Business Combination
Statute under the Oklahoma General Corporation Act, together with certain other
provisions of the HSOG Certificate and HSOG Bylaws, provided sufficient
protection that persons or groups attempting to gain control of HSOG would
likely be forced to negotiate with the HSOG Board in order to effect any
transaction with HSOG or its stockholders. (See "Description of HSOG Capital
Stock--Certain Provisions and Arrangements That May Have an Anti-Takeover
Effect"). Accordingly, the HSOG Board believes that sufficient safeguards exist
to protect the investment interests of the HSOG stockholders even if Article
Nine is eliminated.

     The effect of the elimination of Article Nine of the HSOG Certificate is
that any merger, consolidation or sale of a substantial portion of the assets of
HSOG would require the approval of the holders of a majority, rather than 66 2/3
percent, of the outstanding shares of HSOG voting stock. As discussed above
under Proposed Amendment No. 3, the proposed amendment to Article Eight of the
HSOG Certificate would authorize the HSOG Board to set the number of directors
without obtaining stockholder approval. Should Proposed Amendment No. 3 be
approved by HSOG stockholders but not Proposed Amendment No. 4, the approval of
HSOG stockholders would no longer be necessary to effect a change by the HSOG
Board in the number of directors.

     Approval of Proposed Amendment No. 4 requires the affirmative vote of
holders of at least 66 2/3 percent of the outstanding shares of HSOG Common
Stock. THE BOARD OF DIRECTORS OF HSOG RECOMMENDS THAT HSOG STOCKHOLDERS VOTE
"FOR" PROPOSED AMENDMENT NO. 4 TO THE HSOG CERTIFICATE.

                           Proposed Amendment No. 5
                           ------------------------

                          Proposal Regarding Personal
                            Liability of Directors
                         (Item 2E on HSOG Proxy Card)

     The Board of Directors of HSOG has approved and recommends that the
stockholders of HSOG approve the amendment of the HSOG Certificate to adopt a
new Article Nine which, to the extent permitted by Oklahoma law, would limit the
personal liability of the directors of HSOG to the company or its stockholders
for monetary damages for certain acts or omissions in their capacities as
directors ("Proposed Amendment No. 5"). As permitted under the Oklahoma General
Corporation Act, new Article Nine provides that a director will not be
personally liable for monetary damages for a breach of fiduciary duty as a
director, except for liability (a) for any breach of the director's duty of
loyalty to HSOG or its stockholders, (b) for acts or omissions not in good faith
or that involve a knowing violation of law, (c) under Section 1053 of the
Oklahoma General Corporation Act (which concerns unlawful payments of dividends,
stock purchases or redemptions) or (d) for any transaction from which the
director derived an improper personal benefit. The full text of Proposed
Amendment No. 5 is set forth in Appendix E to this Proxy Statement/Prospectus.

     Directors of public corporations may be subject to substantial potential
liability for actions taken or omitted by them as directors and to significant
expense in defending their conduct. For many years, Oklahoma has recognized the
importance of allowing Oklahoma corporations to provide protection against the
risk to directors' personal resources that could arise out of their service as
directors. The Oklahoma General Corporation Act both permits and, in certain
instances, requires corporations to provide indemnification for directors and
officers in certain situations. 

                                      -68-
<PAGE>
 
The Oklahoma General Corporation Act also specifically permits a corporation to
obtain directors' and officers' liability insurance, including coverage for
certain liabilities against which the corporation cannot provide indemnification
under the Oklahoma General Corporation Act.

     Oklahoma law now specifically permits a corporation to limit the personal
liability of directors to the corporation or its stockholders for damages for
certain acts or omissions by so providing in such corporation's certificate of
incorporation. The purpose of Proposed Amendment No. 5 and the reason it is
being recommended to HSOG stockholders is to enhance HSOG's ability to continue
to attract and retain qualified individuals to serve as directors. Potential
risks of personal liability may deter qualified individuals from continuing, or
accepting, a position as a director of HSOG unless adequate insurance or other
protection is available. By precluding personal liability for certain acts and
omissions, Proposed Amendment No. 5 would supplement the indemnification rights
of directors under the HSOG Bylaws and, if adopted as discussed below at
Proposed Amendment No. 7, under proposed Article Thirteen of the HSOG
Certificate. The HSOG Board believes that the adoption of Proposed Amendment No.
5 will assist HSOG in attracting and retaining qualified directors. It is not,
however, being proposed in response to any specific resignation, threat of
resignation, or refusal to serve by any Board member or potential Board member,
nor is it being proposed in response to any currently pending or threatened
lawsuit or claim against a director.

     In addition, the HSOG Board believes that adoption of Proposed Amendment
No. 5 will permit the directors to exercise their business judgment more freely
by reducing their concern over potential litigation with respect to their
decisions. However, the HSOG Board also believes that the diligence exercised by
directors stems primarily from their desire to act in the best interests of HSOG
and its stockholders, rather than fear of monetary damage awards. Consequently,
the HSOG Board believes that the level of scrutiny and care exercised by
directors will not be lessened by the adoption of Proposed Amendment No. 5.

     Adoption of Proposed Amendment No. 5 would limit the remedies available to
a shareholder seeking to challenge a decision of the Board of Directors, even if
such a decision were grossly negligent, unless the decision fell within one of
the specific categories excepted from coverage described above. Although
equitable remedies such as injunction and rescission would continue to be
available in such cases, the proposed amendment may nevertheless reduce the
likelihood of derivative litigation against directors and may discourage or
deter stockholders or management from bringing a lawsuit against directors for
certain acts or omissions, even though such an action, if successful, might
otherwise have benefitted HSOG and its stockholders.

     Proposed Amendment No. 5 does not eliminate or change a directors'
fiduciary duty and, as indicated above, it would not limit the availability of
equitable remedies such as injunction or rescission based on a director's breach
of those duties. Furthermore, Proposed Amendment No. 5 would not apply to claims
against a director arising out of actions taken in his or her capacity as an
officer of the Company (if he or she is also an officer), and would not limit or
affect the stockholders' ability to seek and obtain relief under any other law,
including the federal securities laws.

     HSOG stockholders should note that because the HSOG's directors may benefit
from the added protection Proposed Amendment No. 5 provides, the directors have
a personal interest in its adoption. However, the Board of Directors of HSOG
believes that Proposed Amendment No. 5 is in the best interests of HSOG and its
stockholders and therefore recommends its adoption.

     Adoption of Proposed Amendment No. 5 will require the affirmative vote of
the holders of a majority of the outstanding shares of HSOG Common Stock. THE
BOARD OF DIRECTORS OF HSOG RECOMMENDS THAT HSOG STOCKHOLDERS VOTE "FOR" PROPOSED
AMENDMENT NO. 5 TO THE HSOG CERTIFICATE.

                           Proposed Amendment No. 6
                           ------------------------

                     Proposal to Authorize the HSOG Board
                 to Amend Bylaws Without Stockholder Approval
                         (Item 2F on HSOG Proxy Card)

     The Board of Directors has approved and recommends that the stockholders of
HSOG approve the amendment of the HSOG Certificate to adopt a new Article
Twelve, which would grant the HSOG Board of Directors the power to adopt, amend
or repeal the Bylaws of HSOG ("Proposed Amendment No. 6"). The full text of
Proposed Amendment No. 6 is set forth in Appendix E to this Proxy
Statement/Prospectus.

     Under the Oklahoma General Corporation Act, any corporation, in its
certificate of incorporation, may confer the power to adopt, amend or repeal the
bylaws upon the directors. The HSOG Certificate does not, however, confer the
power to adopt, amend or repeal the Bylaws upon the directors. In addition, the
HSOG Bylaws provide that only stockholders of HSOG may amend the HSOG Bylaws. As
a result, any change to the provisions of the Bylaws requires such change to be
submitted to the HSOG stockholders for their vote. The HSOG Board believes that
granting directors the right to amend the Bylaws will allow the Board to make
changes it deems appropriate from time to time in order to meet the company's
changing circumstances without first having to go through the cumbersome process
of obtaining stockholder approval. If the Proposed Amendment No. 6 is approved
by HSOG stockholders, the HSOG Board will be authorized, notwithstanding the
provision in the HSOG Bylaws, to amend the Bylaws, and the Board intends to
amend the Bylaws to delete the existing provision therein granting the sole
power to amend the HSOG Bylaws to the HSOG stockholders.

     If the Proposed Amendment No. 6 is approved by HSOG stockholders, the
Oklahoma General Corporation Act provides that HSOG stockholders still retain
the power to also adopt, amend or repeal the HSOG Bylaws. By providing the HSOG
Board with the power to adopt, amend or repeal the HSOG Bylaws, however, the
HSOG Board could, without stockholder approval, amend the Bylaws in a manner
adversely affecting the rights of stockholders.

     Adoption of Proposed Amendment No. 6 will require the affirmative vote of
the holders of a majority of the outstanding shares of HSOG Common Stock. THE
BOARD OF DIRECTORS OF HSOG RECOMMENDS THAT HSOG STOCKHOLDERS VOTE "FOR" PROPOSED
AMENDMENT NO. 6 TO THE HSOG CERTIFICATE.

                           Proposed Amendment No. 7
                           ------------------------

                      Proposal Regarding Indemnification
                            (Item 2G on Proxy Card)

     The Board of Directors of HSOG has approved and recommends that the
stockholders of HSOG approve the amendment of HSOG's Certificate to adopt a new
Article Thirteen dealing with the indemnification of directors, officers,
employees or agents ("Proposed Amendment No. 7"). Proposed Amendment No. 7
provides that the HSOG Board may indemnify and advance expenses to a director,
officer, employee or agent to the maximum extent permitted by Section 1031 of
the Oklahoma General Corporation Act. The full text of Proposed Amendment No. 7
is set forth in Appendix E to this Proxy Statement/Prospectus.

     The HSOG Certificate is currently silent on the subject of indemnification.
Oklahoma law, however, does provide for circumstances in which indemnification
is permitted as well as circumstances in which indemnification is required.
Section 1031 of the Oklahoma General Corporation Act ("Section 1031") permits a
corporation to indemnify officers, directors, employees and agents for actions
taken in good faith and in a manner they reasonably believed to be in, or not
opposed to, the best interests of the corporation, and with respect to any
criminal action, which they had no reasonable cause to believe was unlawful.
Section 1031 provides that a corporation may advance expenses of defense (upon
receipt of a written undertaking to reimburse the corporation if indemnification
is not appropriate) and must reimburse a successful defendant for expenses,
including attorneys' fees, actually and reasonably incurred. Section 1031
provides that indemnification may not be made for any claim, issue or matter as
to which a person has been adjudged by a court of competent jurisdiction, after
exhaustion of all appeals therefrom, to be liable to the 

                                      -70-
<PAGE>
 
corporation, unless and only to the extent a court determines that the person is
entitled to indemnity for such expenses, despite the adjudication of liability,
as the court deems proper.

     The indemnification under Section 1031 is not exclusive of any other right
to which a person seeking indemnification may be entitled under any law, bylaw,
insurance, agreement, vote of stockholders or disinterested directors or
otherwise. In addition, Section 1031 provides that a corporation may purchase
and maintain insurance on behalf of any director, officer, employee or agent of
the corporation against any liability incurred in such capacity, or arising out
of his or her status as such, whether or not the corporation would have the
power to indemnify against such liability under the provisions of Section 1031.

     The HSOG Bylaws currently contain provisions dealing with indemnification
that are substantially similar to Section 1031 and Proposed Amendment No. 7. The
most notable difference is that the HSOG Bylaws provide that the Board of
Directors shall authorize such indemnification that Section 1031 states that
corporations may provide. Proposed Amendment No. 7 tracks the language of
Section 1031 allowing the HSOG Board the discretion as to whom indemnification
would be allowed (except in the circumstances Section 1031 requires mandatory
indemnification for expenses incurred upon the successful defense of an action
as discussed above).

     While the HSOG Bylaws currently provide for indemnification of directors,
officers, employees and agents of HSOG, the HSOG Board believes that the
indemnification provisions are of sufficient importance that they should also be
provided for in the HSOG Certificate. In today's climate of prolific litigation,
the HSOG Board believes that directors and officers serve in partial reliance
upon such indemnification protection. Proposed Amendment No. 7 is intended to
afford additional protection to the reasonable expectations of directors and
officers concerning indemnification and to further enhance HSOG's ability to
retain and recruit qualified directors and officers.

     HSOG stockholders should note that because HSOG's directors may benefit
from the protection of Proposed Amendment No. 7, the directors have a personal
interest in its adoption. However, the HSOG Board believes that Proposed
Amendment No. 7 is in the best interests of HSOG and its stockholders.

     The adoption of Proposed Amendment No. 7 will require the affirmative vote
of the holders of a majority of the outstanding shares of HSOG Common Stock. THE
BOARD OF DIRECTORS OF HSOG RECOMMEND THAT HSOG STOCKHOLDERS VOTE "FOR" PROPOSED
AMENDMENT NO. 7 TO THE HSOG CERTIFICATE.

                           Proposed Amendment No. 8
                           ------------------------

                       Proposal for HSOG to be Governed
                      by Oklahoma General Corporation Act
                         (Item 2H on HSOG Proxy Card)

     The Board of Directors of HSOG has approved and recommends that the
stockholders of HSOG approve an amendment to the HSOG Certificate to adopt a new
Article Fourteen which provides that the Oklahoma General Corporation Act shall
govern HSOG and the rights and liabilities of its constituents ("Proposed
Amendment No. 8"). The text of Proposed Amendment No. 8 is set forth in Appendix
E to this Proxy Statement/Prospectus.

     HSOG was formed prior to the enactment of the Oklahoma General Corporation
Act in 1986. The old Oklahoma Business Corporation Act (the "Old Act") was
repealed with the adoption of the Oklahoma General Corporation Act. Section 1002
of the Oklahoma General Corporation Act specifically provides that such Act
shall be applicable to every corporation incorporated prior to its enactment or
thereafter. However, in a decision handed down in 1992, the Oklahoma Court of
Appeals relied on a savings provision included in the new Oklahoma General
Corporation Act (which was adopted verbatim from the Delaware General
Corporation Law) to determine that certain dissenters' rights granted by the Old
Act survived the enactment of the Oklahoma General Corporation Act with respect
to a corporation formed prior to its enactment.

     The decision by the Oklahoma Court of Appeals, which decision has only
persuasive authority, has created uncertainty with respect to the continued
existence of certain stockholder rights and limitations on corporate activities

                                      -71-
<PAGE>
 
provided under the Old Act that do not exist under the Oklahoma General
Corporation Act. Corporate activities allowed under the Oklahoma General
Corporation Act that were prohibited or not permitted under the Old Act include
(i) permitting corporate loans to officers and employees, (ii) permitting stock
to be sold for a promissory note, (iii) permitting stock repurchases and
dividends out of any surplus as opposed to only earned surplus, and (iv)
permitting stock options to be granted without stockholder approval. Also, under
the Old Act stockholders had dissenters' rights which are not available under
the Oklahoma General Corporation Act with respect to (i) any amendment to the
certificate of incorporation having an adverse effect on a class of
stockholders, reducing the number of directors or changing or altering the
corporate purposes, or (ii) the sale of substantially all of the assets of the
corporation.

     The purpose of the Proposed Amendment No. 8 is to eliminate any uncertainty
with respect to the law governing HSOG. Adoption of Proposed Amendment No. 8
would make it clear, in light of the 1992 Oklahoma Court of Appeals decision,
that HSOG shall be governed by the Oklahoma General Corporation Act. While it is
not certain that stockholders have a valid claim to certain rights accruing
under the Old Act, adoption of the Proposed Amendment No. 8 would eliminate such
rights, including the right to dissent with respect to certain amendments to the
HSOG Certificate or the sale of substantially all the assets of HSOG.

     Adoption of Proposed Amendment No. 8 will require the affirmative vote of
the holders of a majority of the outstanding shares of HSOG Common Stock. THE
BOARD OF DIRECTORS OF HSOG RECOMMENDS THAT HSOG STOCKHOLDERS VOTE "FOR" PROPOSED
AMENDMENT NO. 8 TO THE HSOG CERTIFICATE.

                APPROVAL OF THE HSOG 1997 INCENTIVE STOCK PLAN

     The Board of Directors of HSOG has adopted the HSOG 1997 Incentive Stock
Plan (the "Stock Plan") and has ordered it to be submitted to the HSOG
stockholders for their consideration and approval at the HSOG Meeting. If
approved by HSOG Stockholders, the Stock Plan will only become effective if the
Merger is consummated. A copy of the Stock Plan is attached to this Proxy
Statement/Prospectus as Appendix F, and the following summary is qualified in
its entirety by reference to Appendix F.

     General. The Stock Plan is intended to provide those persons selected to
participate in such plan additional incentive to promote the long-term success
of HSOG, to enable such persons to acquire an equity interest in HSOG, and to
enable HSOG to attract and retain individuals instrumental in contributing to
its success. Officers, key employees and directors, as well as other such
employees or consultants as the Board of Directors selects, are eligible to
receive grants and awards under the Stock Plan.

     The total amount of New HSOG Common Stock initially authorized and reserved
for issuance under the Stock Plan is 451,736 shares (such number is based on the
estimated number of shares to be outstanding after consummation of the Merger).
However, the number of shares reserved for issuance under the Stock Plan shall
automatically increase as necessary so that, when added to the number of shares
subject to stock options granted or restricted stock awarded under the Stock
Plan, such number equals 10% of the issued and outstanding New HSOG Common Stock
(excluding outstanding shares of New HSOG Common Stock issued under the Stock
Plan). No awards have been granted under the Stock Plan.

     The Stock Plan is administered by the HSOG Board of Directors. In the
course of administering the Stock Plan, the HSOG Board of Directors is
authorized to construe and interpret the Stock Plan and to adopt such rules,
regulations, guidelines, subplans, and procedures for carrying out the Stock
Plan as it deems necessary. In addition, the HSOG Board of Directors is
authorized to identify plan participants, determine the types and amounts of
awards to be granted, establish the terms, conditions, and provisions of awards,
prescribe forms of award agreements, establish, amend, and rescind rules and
regulations relating to the Stock Plan, and make all other determinations which
may be necessary or advisable for the administration of the Stock Plan. The HSOG
Board of Directors has not made a determination as to the number of employees
currently eligible for consideration as participants in the Stock Plan.

                                      -72-

     Summary of Awards. The Stock Plan authorizes the grant of stock options and
award of restricted stock. Generally, awards under the Stock Plan will be
granted for no consideration other than prior and future services. Awards under
the Stock Plan do not preclude any salary, incentive, or performance plan
awards, payments under a Company retirement plan, or other benefits that may be
otherwise payable or distributable to any participant, or to such participant's
dependents or beneficiaries under any other plan or policy of HSOG or otherwise.
To the extent permitted by law, awards under the Stock Plan may be made alone,
in combination with, or in substitution for, any other award under the Stock
Plan or other HSOG plan.

     Stock options granted to participants pursuant to the Stock Plan may, at
the discretion of the HSOG Board, be incentive stock options ("ISOs"), within
the meaning of Section 422 of the Internal Revenue Code, or non-qualified stock
options. ISOs, however, may only be awarded to employees of HSOG. The exercise
price of an ISO may not be less than the fair market value of the New HSOG
Common Stock on the date of grant (or 110% of such fair market value in the case
of ISOs granted to employees who own more than 10% of the combined voting power
of all classes of stock of HSOG). In the case of non-qualified stock options,
the exercise price shall be as determined by the HSOG Board in its sole
discretion, except that such price shall not be less than 50% of the fair market
value of the New HSOG Common Stock on the date of grant.

     Stock options granted pursuant to the Stock Plan are exercisable in whole
or in part at such time or times as may be determined by the HSOG Board of
Directors, except that ISOs may not be exercised after the expiration of 10
years from the date granted (or 5 years in the case of ISOs granted to employees
who own more than 10 percent of the combined voting power of all classes of
stock of HSOG). Generally, stock options may be exercised by the payment of
cash, stock, promissory notes, the withholding of shares otherwise issuable upon
exercise or a combination thereof. With respect to options granted to employees
and non-employee directors of HSOG, the stock option agreement may provide for
the automatic grant of "reload options" to replace any shares of New HSOG Common
Stock delivered to HSOG to pay any required withholding tax with respect to the
exercise of a stock option. Such reload options would entitle a participant to
purchase a number of shares of New HSOG Common Stock equal to the number of
shares so delivered to HSOG for payment of the withholding tax at an exercise
price equal to the fair market value of the New HSOG Common Stock at the time of
delivery. A participant may defer the receipt of shares of New HSOG Common Stock
issuable to such participant upon exercise of a non-qualified stock option
pursuant to a written election delivered to the HSOG no later than six months
before the date of exercise. The shares otherwise deliverable to a participant
electing to defer the receipt thereof will be delivered to HSOG for the benefit
of such participant and credited to a bookkeeping account. Any dividends or
other distributions with respect to the deferred shares will be credited to the
participant's account. The deferral may be revoked by delivery of a written
notice of revocation.

     Transferability and Changes Affecting Stock. Awards are not transferable
other than by will, the laws of descent and distribution or other applicable
law; provided, however, awards (other than ISOs) may be transferable to members
of an optionee's immediate family (or a trust for an optionee and/or his or her
family members) or charitable institutions with the consent of the Board of
Directors of HSOG. In the event of a merger, consolidation, reorganization,
recapitalization, stock split, or stock dividend, or a combination or
reclassification of shares, the number of shares of New HSOG Common Stock
reserved under the Stock Plan, the number of shares covered by outstanding stock
options and restricted stock, and the exercise prices of outstanding options
shall be adjusted proportionately. In the event of a change in control of HSOG,
as defined in the Stock Plan, all outstanding awards under the Stock Plan become
free of all restrictions, fully vested and exercisable; provided, however, with
respect to all outstanding stock options, HSOG shall have the right to acquire
any or all outstanding options for which the value of the shares covered
thereby, as established by the change in control, is greater than the exercise
price by paying the excess of such value established by the change in control
over the exercise price.

     Amendment to and Termination of the Stock Plan. The HSOG Board of Directors
may amend, modify, suspend, discontinue, or terminate the Stock Plan without the
consent of stockholders or participants; provided, however, the Board may not
(i) increase the maximum number of shares reserved for issuance under the Plan,
except with stockholder approval, (ii) decrease the exercise price of any option
previously granted or (iii) delegate the administration of the Stock Plan to any
committee. The Stock Plan will terminate on a date selected by the HSOG Board of
Directors in its sole discretion.

                                      -73-
<PAGE>
 
     Federal Income Tax Consequences. An optionee will not realize income for
federal income tax purposes, and HSOG will not be entitled to any deduction, on
the grant of an option under the Stock Plan. Generally, at the time of exercise
of a non-qualified option, an optionee will realize ordinary income for federal
income tax purposes in an amount equal to the excess, if any, of the fair market
value of the shares acquired on the date of exercise over the exercise price.
Any ordinary income realized by an optionee on the exercise of a non-qualified
option (or upon the disqualification of an incentive stock option, as discussed
below) will constitute "wages" for income tax withholding purposes. HSOG will be
entitled to a deduction, as of the date of exercise of an option, in an amount
equal to the ordinary income realized by the optionee. An optionee who exercises
a non-qualified option will have a basis, for federal income tax purposes, in
the shares so acquired equal to the fair market value of such shares on the date
of exercise.

     Under the Plan, an optionee who is granted a non-qualified stock option may
elect to defer the receipt of a portion of the shares of New HSOG Common Stock
deliverable upon the exercise of the option. An optionee who makes such an
election in accordance with the procedures established in the Stock Plan and by
the Board of Directors will recognize no gain for federal income purposes at the
time of exercise. Upon such "deferred exercise," the optionee will receive that
number of shares of New HSOG Common Stock which equals the number of shares
delivered in payment of the exercise price and will assume a tax basis in such
shares equal to his or her tax basis in the delivered shares. The optionee will
realize and recognize ordinary income, and HSOG will be entitled to a deduction,
in the amount of the value of the deferred shares when they are actually
delivered to the optionee in accordance with the optionee's deferral election.
Any distributions made to the optionee in respect to the deferred shares will be
taxed to the optionee as compensation income at the time of such distributions
and the amount of such distributions will be deductible by HSOG.

     The exercise of an ISO will not result in the recognition of ordinary
income or gain by the optionee and will not entitle HSOG to a deduction for
wages paid. The difference between the exercise price for a share of New HSOG
Common Stock under an ISO and the fair market value of such share on the date of
exercise will constitute an item of tax preference under the Alternative Maximum
Tax and therefore may result in a tax liability for an exercising optionee. An
optionee who exercises an ISO will have a basis, for federal income tax
purposes, in the shares so acquired equal to the exercise price for such shares.

     To continue to qualify for the tax treatment set forth above, an optionee
who exercises an ISO must hold the New HSOG Common Stock so acquired for at
least two years after the date of grant of such option and at least one year
after the date of exercise. Failure to adhere to such holding period
requirements will result in the retroactive disqualification of an option as an
ISO with respect to the shares disposed of prematurely.

    If an optionee uses previously acquired New HSOG Common Stock to pay the
exercise price of an option, the new shares so acquired will continue to have
the same status as the old shares used in the acquisition to the extent of the
number of old shares exchanged. Thus, the optionee's basis in such newly-
acquired shares will be equal to his basis in, and his holding period will
include the holding period for, the shares exchanged. Payment of the exercise
price by delivery of previously acquired stock generally postpones the
realization of any taxable capital gain on the unrealized appreciation of the
tendered shares. Any shares which are received in excess of the number of old
shares exchanged will be subject to the regular rules described above upon the
exercise of an option as if the exercise price for such shares is zero.

     Unless an election is made under Section 83(b) of the Code, participants
who receive restricted stock awards will recognize taxable income as of the
earlier of the date on which the restrictions on the restricted stock lapse or
the stock is first transferable in the amount of the fair market value of the
New HSOG Common Stock at that time. Recipients of restricted stock may elect
under Section 83(b) of the Code to report as taxable income in the year of the
restricted stock award an amount of ordinary income equal to the fair market
value (without regard to the restrictions) of the stock at that time. If such an
election is made, the recipient making the election is not required thereafter
to report any further compensation income upon becoming vested in the stock
covered by the election. HSOG will be entitled to a deduction to the extent and
in the year that ordinary income is recognized by the recipient. Dividends paid
on restricted stock awarded under the Stock Plan will be treated as additional
compensation before the restrictions 

                                      -74-
<PAGE>
 
lapse, but are treated as true dividends after the restrictions lapse (or after
a Section 83(b) election). Such dividends paid before the restrictions lapse (or
before a Section 83(b) election) will be deductible by HSOG.

     If a plan participant forfeits the New HSOG Common Stock received pursuant
to a restricted stock award, he or she will not recognize any loss or (even with
respect to income previously recognized as a result of a Section 83(b)
election). Participants will recognize a gain or loss upon the disposition of
their stock equal to the difference between (1) the amount realized on such
disposition and (2) the ordinary income recognized with respect to such stock.
The gain or loss will be recognized as long term, mid term or short term
depending on whether the stock was held for more than 18 months, between 12 and
18 months or 12 months or less, respectively.

                 COMPENSATION AND OTHER INFORMATION CONCERNING
                            OFFICERS AND DIRECTORS

Security Ownership of Certain Beneficial Owners of HSRC and HSOG

     The following table sets forth certain information as of July 31, 1997, and
assuming consummation of the Merger, relating to the beneficial ownership of
HSRC Common Stock, HSOG Common Stock and New HSOG Common Stock, respectively, by
(i) any person known to HSRC or HSOG to own beneficially 5% or more of the
outstanding shares of HSRC Common Stock, HSOG Common Stock or New HSOG Common
Stock, (ii) each director of HSRC and HSOG, (iii) each of the executive officers
named in the Executive Compensation Table below, and (iv) all current executive
officers and directors of HSRC and HSOG as a group. Except as otherwise
indicated, each of the beneficial owners named below is believed by HSRC or
HSOG, as the case may be, to possess sole voting and investment power with
respect to such shares.

Change in Control Severance Plans

     In 1992, the Boards of Directors of HSOG and HSRC adopted The Home-Stake
Oil & Gas Company Change in Control Severance Plan and The Home-Stake Royalty
Corporation Change in Control Severance Plan, respectively 

                                     -78-
<PAGE>
 
(together, the "Severance Plans"). The Severance Plans are designed to provide
severance payments in the event that all or substantially all of the assets or
stock of HSOG or HSRC, as the case may be, are acquired by another party and, if
by reason of such acquisition, an eligible employee's employment with HSOG or
HSRC terminates and no reasonable alternative employment by the acquiring entity
is offered. An "eligible employee" is an employee of HSOG or HSRC, as the case
may be, who is receiving salary for personal services rendered to HSOG or HSRC,
as the case may be, or who would be receiving such remuneration except for a
leave of absence.

     Under the Severance Plans, an eligible employee will not be entitled to
severance pay after a change in control of HSOG or HSRC, as the case may be, if
the acquiring entity offers him or her a salary greater than or equal to 75% of
his or her salary with HSOG or HSRC, as the case may be, immediately prior to
the change in control (exclusive of benefits) and such offer is either (i) at a
location less than 50 miles from the location of his or her employment with HSOG
or HSRC, as the case may be, or (ii) he or she receives a reasonable transfer
allowance.

     Eligible employees who have been employed by HSOG or HSRC, as the case may
be, for less than 5 years will be entitled to two weeks salary for each year of
service as severance pay under the Severance Plans. Eligible employees who have
been employed by HSOG or HSRC, as the case may be, for five years or more will
be entitled to three weeks of salary for each year of service as severance pay.
Department managers identified in the Severance Plans 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 each of the
Severance Plans is one month's salary and the maximum payment is the lesser of
(i) three years' salary or (ii) $1.00 less than the amount which would result in
a significant excise tax under the so-called "excess parachute payment"
provisions of the Internal Revenue Code of 1986, as amended. The Merger will not
constitute a change in control under the Severance Plans.

Employment Contracts

     Robert C. Simpson has an employment agreement to serve as Chief Executive
Officer, President and Treasurer of HSOG and HSRC. The agreement continues until
terminated in accordance with its terms and conditions. Pursuant to the terms of
such agreement, Mr. Simpson currently receives an annual base salary of not less
than $140,000 together with other normal and customary executive officer
benefits. Each of HSOG and HSRC is responsible for one-half of such annual base
salary and benefits. The agreement provides that in the event of termination or
constructive termination (due to a material reduction in functions, duties or
responsibilities or a decrease in the base salary or in other benefits) of Mr.
Simpson's employment for any reason other than his voluntary termination or
termination for due cause, he will be entitled to receive (1) a cash payment
equal to his base salary for one year, (2) a pro rata portion of any bonus due
in respect of the calendar year in which the termination or constructive
termination occurs, and (3) an amount equal to the lesser of $12,000 or fifty
percent (50%) of his annual bonus due in respect of the calendar year in which
the termination or constructive termination occurs. In the event of a
constructive termination during or after a change in control of HSOG and/or
HSRC, Mr. Simpson will also be entitled to receive an additional cash payment
equal to his base salary for one year from the date of the constructive
termination. None of the other executive officers of HSOG or HSRC has any
arrangement or understanding with any person with respect to any future
employment by HSOG or HSRC. The Merger will not effect the change in control
provisions of the employment agreement. Subsequent to the Merger, HSOG will
become obligated for 100% of Mr. Simpson's salary and other benefits under the
employment agreement.

Certain Relationships and Related Transactions

     HSOG and HSRC are under common management and both companies frequently
participate jointly in the acquisition of mineral and leasehold interests and in
exploration and development activities. Each company generally owns an equal
interest in the oil and gas properties in which they jointly participate,
however such interests may vary. Only HSRC, however, serves as operator on
properties that are not operated by outside parties. In accordance with oil and
gas industry practice, the oil and gas ventures in which both companies
participate are considered to be joint, but separate. For those properties
operated by outside parties, each of HSOG and HSRC is generally billed
separately for its share of operating and drilling costs and separately
reimburse the operator for those costs. For properties operated by HSRC, HSOG is
billed for such costs monthly.

     Payroll costs for personnel of HSOG are paid by HSRC and HSOG reimburses
HSRC for its one-half share of such costs. For substantially all other general
and administrative costs, each Company separately pays for its one-half share.

     For the years ended December 31, 1996 and 1995, HSRC paid or billed, as
indicated, HSOG the following amounts:

                    Unaudited Pro Forma Financial Statements

The accompanying unaudited pro forma financial statements have been prepared to
illustrate the effects of the proposed merger between HSOG and HSRC ("the
Companies").

The unaudited pro forma balance sheet as of June 30, 1997 gives effect to the
merger as if it had occurred on that date. The unaudited pro forma statements of
operations for the six months ended June 30, 1997 and 1996, and the years ended
December 31, 1996 and 1995, give effect to the merger as if it had occurred on
January 1, 1995. Such unaudited pro forma financial information has been
prepared based on estimates and assumptions deemed by management to be
appropriate and does not purport to be indicative of the financial position or
results of operation which may be attained in the future. Future results may
vary significantly from the results reflected in the unaudited pro forma
statements of operations due to oil and gas production fluctuations, changes in
product prices, future acquisitions and divestitures, future development and
exploration activities and other factors.

The unaudited pro forma financial information should be read in conjunction with
the historical financial statements and "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

HSRC's merger with HSOG will be accounted for in a manner similar to a pooling
of interests. In considering the appropriate business combination method of
accounting to be used by HSOG, several factors were taken into consideration,
including (i) there are no new stockholders resulting from such transaction and
the economic interest of each stockholder remains the same after the merger,
(ii) both companies have common managements and offices and have been jointly
operated for many years, (iii) both companies own equal and common ownership in
most assets, and (iv) the common ownership and control is very strong, with over
80% of the common stock of each company owned by the same shareholders.

                       The Home-Stake Oil & Gas Company
               Notes to Unaudited Pro Forma Financial Statements


     Note 1 - Pro Forma Adjustments

     (a) Eliminate the intercompany receivable / payable between the companies.

     (b) Eliminate the intercompany investments of each company in the other's
         stock and reflect the cancellation of the related common stock.

     (c) Cancellation of the treasury stock owned by each company.

     (d) Reclassification to the change in par value of the HSOG Common Stock to
         $.01 per share, based on resulting shares issued and outstanding
         following the Merger and Stock Split.

     (e) Eliminate the income from equity affiliates associated the stock each
         company owns in the other.

     (f) Eliminate the amortization of the excess of the investment of each
         company in the underlying equity in net assets of the other.

     (g) Estimated provision for income taxes attributable to the pro forma
         merger of the companies.

     Note 2 - Income Per Share

     Pro forma income per share is calculated on the assumption that the merger
     of The Home-Stake Companies had occurred on January 1, 1995, on the basis
     described in this Proxy Statement/Prospectus, wherein holders of HSOG
     Common Stock will receive 30 shares of New HSOG Common Stock, holders of
     HSRC Common Stock will receive 48.66 shares on common stock of New HSOG
     Common Stock, and all treasury shares and shares owned by each company in
     the other will be canceled.

     Note 3 - Provision for Income Taxes

     The pro forma adjustments related to the provisions for income tax differ
     significantly from the "expected" provisions due principally to the unusual
     nature of the necessary income tax adjustments associated with the proposed
     merger.  The most significant adjustment relates to the loss of certain
     allowable statutory depletion deductions by the merged entity that are
     currently available to each of the Companies separately.  For the periods
     presented, the increase in current income tax expense associated with the
     loss of such deductions is largely offset by the effects of the alternative
     minimum tax credit carryforwards available to offset current and future
     income taxes.

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                                  (Unaudited)

Note 1 - General

The unaudited financial information provided in these interim condensed
financial statements includes all normal recurring adjustments which are, in the
opinion of management, necessary to fairly present the financial position,
result of operations and cash flows of the Company. Certain information and
footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been omitted or
condensed. The Company believes that the disclosures herein are adequate to make
the information presented not misleading; however, these financial statements
should be read in conjunction with the audited financial statements and related
notes thereto included herein.

The results for interim periods are not necessarily indicative of trends or of
results to be expected for the full year.

Note 2- Summarized financial information of equity investees

Summarized income statement information for the six months ended June 30, 1997
and 1996 for The Home-Stake Royalty Corporation ("HSRC") and Alden Pipeline
Company is presented below:

<TABLE>
<CAPTION>
 
                                         1997         1996

<S>                                   <C>          <C>
Income Statement data:
       Revenues....................   $4,351,608   $3,776,556
       Income before income taxes..    1,509,954    1,001,057
       Net income /(1)/............    1,091,138      754,245
</TABLE>

       /(1)/ Includes $271,139 and $138,829 in 1997 and 1996, respectively,
       attributable to the equity earnings of the Company recorded by HSRC.

During the first quarter of 1997, the Company sold its interest in the N.E.
Alden Field, including Alden Pipeline Company. This sale was effective January
1, 1997. Accordingly, 1997 information presented above does not include amounts
attributable to the operations of Alden Pipeline Company; amounts included for
1996 operations are not material to the totals shown.

Note 3 - Note payable

Note payable at June 30, 1997, represents the amounts due under the Company's
financing agreement which is due May 1, 1998, and provides for monthly
maturities of $114,110, plus interest at bank prime. In addition, the Company
has a line of credit in the amount of $500,000 available until May 1, 1998,
which provides for monthly payments of interest on the outstanding borrowings at
bank prime. There is no balance under this line, however the Company has issued
letters of credit in the amount of $60,000 which are also guaranteed by this
line.

The notes payable and line of credit described above are collateralized by
certain of the Company's producing properties.

Note 4 - Contingencies

The Company is involved in various legal actions arising in the normal course of
business. In the opinion of management, the Company's liabilities, if any, in
these matters will not have a material effect on the Company's financial
position or the results of operations.

                        REPORT OF INDEPENDENT AUDITORS



The Board of Directors and Stockholders
The Home-Stake Oil & Gas Company

We have audited the accompanying consolidated balance sheets of The Home-Stake
Oil & Gas Company as of December 31, 1996 and 1995, and the related consolidated
statements of income and accumulated deficit and cash flows for the years then
ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of The Home-Stake Oil
& Gas Company at December 31, 1996 and 1995, and the consolidated results of its
operations and its cash flows for the years then ended in conformity with
generally accepted accounting principles.

                        THE HOME-STAKE OIL & GAS COMPANY
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Description of business

The Home-Stake Oil & Gas Company is an "independent oil and gas producer"
actively engaged in the acquisition, exploration, development and production of
oil and gas properties. Oil and gas exploration and production activities are
subject to numerous risks inherent in the business. These include the volatility
of oil and gas prices, environmental concerns and governmental regulations,
general business risks and hazards involving the acquisition and operation of
oil and gas properties, the ability to continue to find new reserves to replace
those being depleted and the highly competitive nature of the business. Its
principal geographic operating areas lie within the states of Oklahoma, Montana
and Texas.

Note 1 - Summary of significant accounting policies

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and
its wholly owned subsidiary H-S Gas System, Inc. The equity method is used when
the Company appropriately participates in control of the investee, but has less
than a 50% interest. Under the equity method, original investments are recorded
at cost and adjusted by the Company's share of undistributed earnings or losses
of those companies. Dividends and distributions are credited against the
investment when received.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with generally accepted
accounting principals requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities at the date of the
financial statements and revenues and expenses during the reporting period.
Actual results could differ from those estimates.

One of the most significant estimates made by the Company involves its oil and
gas reserves. The Company amortizes its costs of producing properties on the
unit-of-production method over the estimated remaining reserves of the Company.
Since estimates of remaining oil and gas reserves are highly subjective and
subject to constantly changing conditions, most of which are beyond the control
of the Company, it is reasonably possible that the Company's estimates will
change over time, affecting the rates of amortization. In addition, in assessing
whether any impairment to the carrying values of producing properties has
occurred, these same estimates of oil and gas reserves are used. Consequently
impairment adjustments to the carrying values are reasonably possible.

Fair Value of Financial Instruments

The carrying amounts for cash and cash equivalents and note payable reported in
the balance sheets approximate fair value.

Cash and cash equivalents

The Company includes certificates of deposit and money market funds in cash and
cash equivalents since such amounts are readily convertible into known amounts
of cash.

Credit risks

The Company sells its oil and gas production, which is located primarily in
Montana, Oklahoma and Texas, directly or indirectly to numerous oil refiners and
pipeline companies without collateral. The Company believes its credit risks are
limited due to the nature of its business and purchaser base and has not
incurred any significant losses in connection therewith.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

Note 1 - Summary of significant accounting policies (continued)

Environmental costs

Environmental liabilities, which historically have not been material, are
recognized when it is probable that a loss has been incurred and the amount of
that loss is reasonably estimable. Environmental liabilities, when accrued, are
based upon estimates of expected future costs without discounting. At December
31, 1996 there are no such costs accrued. The Company's policy is in compliance
with Statement of Position 96-1, Environmental Remediation Liabilities, issued
by the Accounting Standards Executive Committee of the American Institute of
Certified Public Accountants and issuance of this statement had no impact on the
Company's financial position or results of operations.

Property and equipment

The Company follows the successful efforts method of accounting for its oil and
gas operations. Costs of productive oil or gas wells, as well as costs of
acquiring producing and nonproducing oil and gas properties, are capitalized.
Exploratory costs, annual delay rentals and exploratory dry holes are expensed.

Depreciation, depletion and amortization of producing properties are provided on
the unit-of-production method based on estimates of proved reserves.
Depreciation of other property and equipment is provided on straight-line or
accelerated methods over estimated useful lives.

In 1995, the Company adopted Statement of Financial Accounting Standards No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed of" (SFAS No. 121). Adoption of SFAS No. 121, which
generally limits the carrying value of producing properties to their discounted
estimated future net cash flows, had no retroactive impact on net income in 1995
since the Company has followed a similar policy since 1986. Adjustments under
this policy are included in depreciation, depletion and amortization and totaled
$87,469 and $137,180 in 1996 and 1995, respectively.

Nonproducing oil and gas properties include both perpetual mineral rights and
term leasehold interests. The perpetual mineral rights are written-off when
unsuccessful exploration information is obtained. The Company does not maintain
an extensive inventory of nonproducing leasehold interests, rather such
interests are acquired in connection with specific drilling objectives. Such
nonproducing leasehold interests are written-off or reserved as warranted by
drilling results.

Renewals and betterments are capitalized; maintenance and repairs are charged to
expense. Replacement of individual items of lease equipment are capitalized.
When leases or other assets are sold or retired, the cost and related
accumulated depreciation, depletion and amortization are eliminated from the
accounts and the resulting gain or loss is recognized in income. The Company's
historical experience has been that the salvage value of equipment on property
abandonments is sufficient to cover the costs of dismantlement and site
restoration. Therefore, the Company does not accrue such costs and salvage value
is not considered in calculating property amortization.

Oil and gas sales

The Company sells most of its crude oil and natural gas concurrent with
production and does not store significant volumes for future sales. Revenue is
recognized on the "sales method" when oil and gas are sold.

Note 1 - Summary of significant accounting policies (continued)

Income taxes

Certain income and expense items are recorded in one year in the financial
statements and are reported in a different year in the income tax return. Such
items generally include tax credit carryforwards, intangible drilling and
development costs, depreciation and depletion. The tax effects associated with
these differences are recorded in these financial statements and described as
"deferred income taxes".

Note 2 - Related party transactions and investments

The Company is under common management with The Home-Stake Royalty Corporation
("HSRC"), with which it frequently participates jointly in the acquisition of
mineral and leasehold interests and in exploration and development activities.
Each company generally owns an equal interest in the oil and gas properties in
which they jointly participate, however such interests may vary. Only HSRC,
however, serves as operator on properties that are not operated by outside
parties.

In 1995 the Boards of Directors of the Company and HSRC voted to change the
participation arrangement between the Companies such that effective January 1,
1996, the Company participated with a 40% interest in joint ventures (drilling,
acquisitions and/or other investments) between the Company and HSRC, with HSRC
participating in such ventures with a 60% interest. Joint general and
administrative expenses continue to be shared on a 50-50 basis. The Boards felt
this change was in the best interests of each company, based on a review of
their respective financial conditions. This participation arrangement is
reviewed by the Boards on an annual basis and future changes will be made as
circumstances, in the judgment of the Boards, require.

In accordance with oil and gas industry practice, the oil and gas ventures in
which both companies participate are considered to be joint, but separate. For
those properties operated by outside parties, each Company is generally billed
separately for their share of operating and drilling costs and separately
reimburses the operator for those costs. For properties operated by HSRC, the
Company is billed for such costs monthly.

Payroll costs for personnel are paid by HSRC and the Company reimburses HSRC for
its one-half share of such costs. For substantially all other general and
administrative costs, each Company separately pays for its one-half share.

For the two years ended December 31, HSRC paid or billed the Company the
following amounts:

</TABLE>

At December 31, 1996, the Company had nonexpiring alternative minimum tax credit
carryforwards of approximately $476,900 and statutory depletion carryforwards of
approximately $298,400, both available to reduce future federal income taxes,
the benefits of which have been recognized in these financial statements.

Note 5 - Benefit plans

Effective January 1, 1994, the Company and HSRC adopted The Home-Stake Companies
Profit Sharing 401(k) Plan. The plan covers substantially all the Company's
employees that have completed one year of service and provides for a mandatory
Company contribution equal to 3% of the employee's compensation and an
additional matching Company contribution of up to 3%. Company contributions to
the Plan were $21,286 and $22,731 in 1996 and 1995, respectively.

Note 6 - Commitments and contingencies

The Company has a non-cancelable operating lease covering its office space
through December 30, 2000. This lease provides for annual rental payments of
$55,908, subject to an annual expense adjustment.

On June 13, 1996, the Company and HSRC filed suit in the United States District
Court for the Eastern District of Oklahoma against Mobil Oil Corporation and
Mobil Exploration & Production U.S., Inc. (collectively "Mobil"). This suit was
styled The Home-Stake Royalty Corporation and The Home-Stake Oil & Gas Company v
       -------------------------------------------------------------------------
Mobil Oil Corporation and Mobil Exploration & Production U.S., Inc. (Case No.
- -------------------------------------------------------------------
CIV-96-271-S). This action concerned Mobil's operation of a waterflood unit in
which the Company and HSRC each own a 9% working interest. The Company and HSRC
sought actual damages, punitive damages and equitable relief in this matter.
Mobil counterclaimed for the Company's and HSRC's shares of environmental costs
which they had not paid. In late December 1996, this matter was settled, with
the Company and HSRC each receiving $365,000 from Mobil which was credited to
the carrying value of the Company's investment in the property. In connection
with Mobil's counterclaim, the Company and HSRC agreed to pay the unpaid
environmental costs. In January 1997, the Company and HSRC filed claims with
their pollution insurance carrier for the reimbursement of $187,800 ($93,900
each company), representing the Company's share of surface owner settlement
costs paid. The Company has not received a response to this claim and has not
accrued any amounts attributable to the expected insurance reimbursement. In
addition, the operator is still working to reach settlements with remaining
surface owners. It is currently estimated that the Company's share of such
additional costs may total as much as $50,000. However, any amounts paid by the
Company should be covered under the Company's pollution insurance policy.

                                      F-23
<PAGE>

Note 6 - Commitments and contingencies (continued)

The Company is involved in various legal actions arising in the normal course of
business. In the opinion of management and legal counsel, the Company's
liabilities, if any, in these matters will not have a material effect on the
Company's financial position, results of operations or cash flows.

Note 7 - Shareholder rights plan

On May 29, 1991, the Company adopted a Rights Plan and distributed to its
shareholders one Right for each outstanding share of common stock. Each Right
entitles the holder to purchase one-tenth of an additional share of common stock
from the Company and acquire a note payable from the Company to the holder or,
under certain circumstances, purchase the stock of an acquiring company. Upon
the occurrence of certain specified events related to a change in control of the
Company, each holder of a Right (other than a potential acquiror) will have the
right to acquire, upon exercise, shares of the Company's common stock at one-
half of the then current market price. The Rights expire January 1, 2000, and
are exercisable only if a person or group acquires 15% or more of the Company's
common stock or commences a tender offer that would result in a person or group
acquiring 15% or more of the Company's common stock. The Rights are redeemable
in whole, but not in part, at a price of $.01 per Right, payable in cash or
stock.

The Company's share of net proved oil and gas reserves of investees accounted
for on the equity method (see Note 2 to the Consolidated Financial Statements)
at December 31, 1996, was 469,513 barrels of oil and 1,705,334 Mcf of gas, and
at December 31, 1995 was 471,520 barrels of oil and 1,702,544 Mcf of gas.

The estimates of oil and gas reserves were prepared by Company employees and do
not include proved undeveloped reserves attributable to either royalty interests
(information is not available) or outside operated working interests (quantities
are not considered significant to total Company proved reserves). Furthermore,
these estimates do not include reserves whose estimates or recoverability are
less precise, commonly referred to as "probable" or "possible" reserves. The
Company has no reserves outside the continental United States.

   SUPPLEMENTARY INFORMATION ON OIL AND GAS PRODUCING ACTIVITIES (unaudited)

Standardized measure of discounted future net cash flows

In accordance with the requirements of Statement of Financial Accounting
Standards No. 69 ("SFAS No. 69") presented below are projections of future net
oil and gas cash flows (sales less production taxes, operating expenses, certain
development costs and estimated income taxes) and related present values of
proved oil and gas reserves. As required by SFAS No. 69, these projections are
based on end of period prices and costs, held constant for all future periods.
Present values of the future net oil and gas cash flows were calculated using a
10% discount factor as required. While this information was developed with
reasonable care and disclosed in good faith, it is emphasized that some of the
data are necessarily imprecise and represent only approximate amounts because of
the subjective judgments involved in developing such information. Accordingly,
this information may not represent the present financial condition of the
Company or its expected future results. This information does not include any
amounts applicable to "probable" or "possible" reserves which may become proved
in the future.

Although these disclosures have been prepared in accordance with SFAS No. 69,
this information does not purport to present the fair market value of the
Company's oil and gas properties or a fair estimate of the present value of
future cash flows expected to be obtained from their production. The reserve
estimates, while carefully made, may be significantly revised based on future
events. In addition, estimates of the timing of production, actual prices
realized and related production costs and taxes may also vary significantly from
those used in these calculations.

                       THE HOME-STAKE ROYALTY CORPORATION
                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                                  (Unaudited)

Note 1 - General

The unaudited financial information provided in these interim condensed
financial statements includes all normal recurring adjustments which are, in the
opinion of management, necessary to fairly present the financial position,
result of operations and cash flows of the Company.  Certain information and
footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been omitted or
condensed.  The Company believes that the disclosures herein are adequate to
make the information presented not misleading; however, these financial
statements should be read in conjunction with the audited financial statements
and related notes thereto included herein.

The results for interim periods are not necessarily indicative of trends or of
results to be expected for the full year.

Note 2 - Summarized financial information of equity investees

Summarized income statement information for the six months ended June 30, 1997
and 1996, for The Home-Stake Oil & Gas Company ("HSOG") and Alden Pipeline
Company is presented below:

<TABLE>
<CAPTION>
 
                                           1997         1996
                                           ----         ----
<S>                                      <C>          <C>
Income Statement data:
          Revenues....................   $4,027,653   $3,600,334
          Income before income taxes..    1,256,381      749,024
          Net income /(1)/............      941,663      499,636
</TABLE>

          /(1)/ Includes $165,989 and $120,010 in 1997 and 1996, respectively,
          attributable to the equity earnings of the Company recorded by HSOG.

During the first quarter of 1997, the Company sold its interest in the N.E.
Alden Field, including Alden Pipeline Company.  This sale was effective January
1, 1997.  Accordingly, 1997 information presented above does not include amounts
attributable to the operations of Alden Pipeline Company; amounts included for
1996 operations are not material to the totals shown.

Note 3 - Note payable

On May 31, 1997, the Company paid-off its bank note payable which was due May 1,
1998.  The Company has a line of credit in the amount of $700,000 available
until May 1, 1998, which provides for monthly payments of interest on the
outstanding borrowings at bank prime.  There is no balance under this line,
however the Company has issued a letter of credit in the amount of $60,000 which
is guaranteed by this line.

The note payable and line of credit described above are collateralized by
certain of the Company's producing properties.

Note 4 - Contingencies

The Company is involved in various other legal actions arising in the normal
course of business.  In the opinion of management, the Company's liabilities, if
any, in these matters will not have a material effect on the Company's financial
position or the results of operations.

                         REPORT OF INDEPENDENT AUDITORS



To the Board of Directors and Stockholders
The Home-Stake Royalty Corporation

We have audited the accompanying consolidated balance sheets of The Home-Stake
Royalty Corporation as of December 31, 1996 and 1995, and the related
consolidated statements of income and retained earnings and cash flows for the
years then ended. These financial statements are the responsibility of the
Company's management.  Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of The Home-Stake
Royalty Corporation at December 31, 1996 and 1995, and the consolidated results
of its operations and its cash flows for the years then ended in conformity with
generally accepted accounting principles.

                      THE HOME-STAKE ROYALTY CORPORATION
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Description of business

The Home-Stake Royalty Corporation is an "independent oil and gas producer"
actively engaged in the acquisition, exploration, development and production of
oil and gas properties. Oil and gas exploration and production activities are
subject to numerous risks inherent in the business. These include the volatility
of oil and gas prices, environmental concerns and governmental regulations,
general business risks and hazards involving the acquisition and operation of
oil and gas properties, the ability to continue to find new reserves to replace
those being depleted and the highly competitive nature of the business. Its
principal geographic operating areas lie within the states of Oklahoma, Montana
and Texas.

Note 1 - Summary of significant accounting policies

Principles of consolidation

The consolidated financial statements include the accounts of the Company and
its wholly owned subsidiary Alden Gas Gathering Company. The equity method is
used when the Company has a 20% to 50% interest in other companies. Under the
equity method, original investments are recorded at cost and adjusted by the
Company's share of undistributed earnings and losses of these companies.
Dividends and distributions are credited against the investment when received.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with generally accepted
accounting principals requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities at the date of the
financial statements and revenues and expenses during the reporting period.
Actual results could differ from those estimates.

One of the most significant estimates made by the Company involves its oil and
gas reserves. The Company amortizes its costs of producing properties on the
unit-of-production method over the estimated remaining reserves of the Company.
Since estimates of remaining oil and gas reserves are highly subjective and
subject to constantly changing conditions, most of which are beyond the control
of the Company, it is reasonably possible that the Company's estimates will
change over time, affecting the rates of amortization. In addition, in assessing
whether any impairment to the carrying values of producing properties has
occurred, these same estimates of oil and gas reserves are used. Consequently
impairment adjustments to the carrying values are reasonably possible.

Fair Value of Financial Instruments

The carrying amounts for cash and cash equivalents and notes payable reported in
the balance sheets approximate fair value.

Cash and cash equivalents

The Company includes certificates of deposit and money market funds in cash and
cash equivalents since such amounts are readily convertible into known amounts
of cash.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

Note 1 - Summary of significant accounting policies (continued)

Credit risks

The Company sells its oil and gas production, which is located primarily in
Montana, Oklahoma and Texas, directly or indirectly to numerous oil refiners and
pipeline companies without collateral. In addition, the Company has numerous
working interest owners to whom it grants credit on wells in which it serves as
operator. Substantially all of these owners are industry partners or individuals
who invest in oil and gas drilling ventures. The Company believes its credits
risks are limited due to nature of its business and partner base and has not
incurred any significant losses in connection therewith.

Environmental costs

Environmental liabilities, which historically have not been material, are
recognized when it is probable that a loss has been incurred and the amount of
that loss is reasonably estimable. Environmental liabilities, when accrued, are
based upon estimates of expected future costs without discounting. At December
31, 1996 there are no such costs accrued. The Company's policy is in compliance
with Statement of Position 96-1, Environmental Remediation Liabilities, issued
by the Accounting Standards Executive Committee of the American Institute of
Certified Public Accountants and issuance of this statement had no impact on the
Company's financial position or results of operations.

Property and equipment

The Company follows the successful efforts method of accounting for its oil and
gas operations. Costs of productive oil or gas wells, as well as costs of
acquiring producing and nonproducing oil and gas properties, are capitalized.
Exploratory costs, annual delay rentals and exploratory dry holes are expensed.

Depreciation, depletion and amortization of producing properties are provided on
the unit-of-production method based on estimates of proved reserves.
Depreciation of other property and equipment is provided on straight-line or
accelerated methods over estimated useful lives.

In 1995, the Company adopted Statement of Financial Accounting Standards No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed of" (SFAS No. 121). Adoption of SFAS No. 121, which
generally limits the carrying value of producing properties to their discounted
estimated future net cash flows, had no retroactive impact on net income in 1995
since the Company has followed a similar policy since 1986. Adjustments under
this policy are included in depreciation, depletion and amortization and totaled
$91,107 and $139,031 in 1996 and 1995, respectively.

Nonproducing oil and gas properties include both perpetual mineral rights and
term leasehold interests. The perpetual mineral rights are written-off when
unsuccessful exploration information is obtained. The Company does not maintain
an extensive inventory of nonproducing leasehold interests, rather such
interests are acquired in connection with specific drilling objectives. Such
nonproducing leasehold interests are written-off or reserved as warranted by
drilling results.

Renewals and betterments are capitalized; maintenance and repairs are charged to
expense. Replacement of individual items of lease equipment are capitalized.
When leases or other assets are sold or retired, the cost and related
accumulated depreciation, depletion and amortization are eliminated from the
accounts and the resulting gain or loss is recognized in income. The Company's
historical experience has been that the salvage value of equipment on property
abandonments is sufficient to cover the costs of dismantlement and site
restoration. Therefore, the Company does not accrue such costs and salvage value
is not considered in calculating property amortization.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)
 
Note 1 - Summary of significant accounting policies (continued)

Oil and gas sales

The Company sells most of its crude oil and natural gas concurrent with
production and does not store significant volumes for future sales. Revenue is
recognized on the "sales method" when oil and gas are sold.

Income taxes

Certain income and expense items are recorded in one year in the financial
statements and are reported in a different year in the income tax return. Such
items generally include tax credit carryforwards, intangible drilling and
development costs, depreciation and depletion. The tax effects associated with
these differences are recorded in these financial statements and described as
"deferred income taxes".

Note 2 - Related party transactions and investments

The Company is under common management with The Home-Stake Oil & Gas Company
("HSOG"), with which it frequently participates jointly in the acquisition of
mineral and leasehold interests and in exploration and development activities.
Each company generally owns an equal interest in the oil and gas properties in
which they jointly participate, however such interests may vary. Only the
Company, however, serves as operator on properties that are not operated by
outside parties.

In 1995, the Boards of Directors of the Company and HSOG voted to change the
participation arrangement between the Companies such that effective January 1,
1996, the Company participated with a 60% interest in joint ventures (drilling,
acquisitions and/or other investments) between the Company and HSOG, with HSOG
participating in such ventures with a 40% interest. Joint general and
administrative expenses continue to be shared on a 50-50 basis. The Boards felt
this change was in the best interests of each company, based on a review of
their respective financial conditions. This participation arrangement is
reviewed by the Boards on an annual basis and future changes will be made as
circumstances, in the judgement of the Boards, require.

In accordance with oil and gas industry practice, the oil and gas ventures in
which both companies participate are considered to be joint, but separate. For
those properties operated by outside parties, each Company is generally billed
separately for their share of operating and drilling costs and separately
reimburse the operator for such costs. For properties operated by the Company,
HSOG is billed for such costs monthly by the Company.

Payroll costs for personnel are paid by the Company and HSOG reimburses the
Company for its one-half share of such costs. For substantially all other
general and administrative costs, each Company separately pays for its one-half
share.

For the two years ended December 31, the Company paid or billed HSOG the
following amounts:

     Note 2 - Related party transactions and investments (continued)

     All revenues and expenses described above are paid by the respective
     company in cash on a monthly basis.

     In November 1996, the Company acquired an additional 1,928 shares of HSOG
     at a cost of $195,178.  At December 31, 1996, the Company owns 33.9% of the
     outstanding common stock of HSOG and accounts for its investment in HSOG
     using the equity method.  In November 1996, HSOG acquired an additional
     1,493 shares of the Company. At December 31, 1996, HSOG owns 19.3% of the
     outstanding common stock of the Company.   In addition, the Company owns a
     41% interest in Alden Pipeline Company, a general partnership carried on
     the equity method.  These investments do not have quoted market values.  In
     March 1997, the Company sold its interest in Alden Pipeline Company and the
     related producing properties at a gain of approximately $100,000.

     At July 1, 1991, when the Company adopted equity accounting for its
     investment in HSOG, the amount of investment included costs of $1,527,439
     in excess of the underlying equity in net assets which is being amortized
     into income over ten years.

     At December 31,  investments consisted of the following:

     Interest is at bank prime (8.25% at December 31, 1996) and the note is
     collateralized by certain of the Company's producing properties having a
     book value at December 31, 1996 of $5,254,816.  In addition, the Company
     has a bank line of credit in the amount of $700,000 available until May 1,
     1997 which provides for monthly payments of interest on the outstanding
     borrowings at bank prime.  In connection with this line of credit, the
     Company has issued a letter of credit in the amount of $60,000, which is
     guaranteed by this line, and pays a commitment fee of one-half of one
     percent (1/2%) per annum on the unused portion of the line.

     In connection with the Company's bank loans, there are certain loan
     covenants which require, among other things, that the Company maintain
     certain financial ratios and minimum net worth requirements.  In addition,
     the Company's annual cash dividends are limited to the lesser of $425,000
     or net income.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

     Note 4 - Income taxes (continued)

     At December 31, 1996, the Company had nonexpiring alternative minimum tax
     credit carryforwards of approximately $185,800 available to reduce future
     federal income taxes, the benefits of which have been recognized in these
     financial statements.

     Note 5 - Benefit plans
 
     Effective January 1, 1994 the Company and HSOG adopted The Home-Stake
     Companies Profit Sharing 401(k) Plan.  The plan covers substantially all
     the Company's employees that have completed one year of service and
     provides for a mandatory Company contribution equal to 3% of the employee's
     compensation and an additional matching Company contribution of up to 3%.
     Company contributions to the Plan were $22,288 and $23,048 in 1996 and
     1995, respectively.

     Note 6 - Commitments and contingencies

     The Company has a non-cancelable operating lease covering its office space
     through December 30, 2000.  This lease provides for annual rental payments
     of $55,908, subject to an annual expense adjustment.

     On June 13, 1996, the Company and HSOG filed suit in the United States
     District Court for the Eastern District of Oklahoma against Mobil Oil
     Corporation and Mobil Exploration & Production U.S., Inc. (collectively
     "Mobil").  This suit was styled The Home-Stake Royalty Corporation and The
                                     ------------------------------------------
     Home-Stake Oil & Gas Company v Mobil Oil Corporation and Mobil Exploration
     --------------------------------------------------------------------------
     & Production U.S., Inc. (Case No. CIV-96-271-S).  This action concerned
     -----------------------                                                
     Mobil's operation of a waterflood unit in which the Company and HSOG each
     own a 9% working interest.  The Company and HSOG sought actual damages,
     punitive damages and equitable relief in this matter.  Mobil counterclaimed
     for the Company's and HSOG's shares of environmental costs which they had
     not paid.  In late December 1996, this case was settled, with the Company
     and HSOG each receiving $365,000 from Mobil which was credited to the
     carrying value of the Company's investment in the property.  In connection
     with Mobil's counterclaim, the Company and HSOG agreed to pay the unpaid
     environmental costs.  In January 1997, the Company and HSOG filed claims
     with their pollution insurance carrier for the reimbursement of $187,800
     ($93,900 each company), representing the Company's share of surface owner
     settlement costs paid. The Company has not received a response to this
     claim and has not accrued any amounts attributable to the expected
     insurance reimbursement.  In addition, the operator is still working to
     reach settlements with remaining surface owners.  It is currently estimated
     that the Company's share of such additional costs may total as much as
     $50,000.  However, any amounts paid by the Company should be covered under
     the Company's pollution insurance policy.

     In addition, the Company is involved in various other legal actions arising
     in the normal course of business.  In the opinion of management and legal
     counsel, the Company's liabilities, if any, in these matters will not have
     a material effect on the Company's financial position, results of
     operations or cash flows.

     Note 7 - Shareholder rights plan

     On May 29, 1991, the Company adopted a Rights Plan and distributed to its
     shareholders one Right for each outstanding share of common stock.  Each
     Right entitles the holder to purchase one-tenth of an additional share of
     common stock from the Company and acquire a note payable from the Company
     to the holder or, under certain circumstances, purchase the stock of an
     acquiring company.  Upon the occurrence of certain specified events related
     to a change in control of the Company, each holder of a Right (other than a
     potential acquiror) will have the right to acquire, upon exercise, shares
     of the Company's common stock at one-half of the then current market price.
     The Rights expire January 1, 2000, and are exercisable only if a person or
     group acquires 15% or more of the Company's common stock or commences a
     tender offer that would result in a person or group acquiring 15% or more
     of the Company's common stock. The Rights are redeemable in whole, but not
     in part, at a price of $.01 per Right, payable in cash or stock.

</TABLE>

The Company's share of net proved oil and gas reserves of investees accounted
for on the equity method (see Note 2 to the Consolidated Financial Statements)
at December 31, 1996, was 808,161 barrels of oil and 2,881,865 Mcf of gas, and
at December 31, 1995 was 865,832 barrels of oil and 3,083,948 Mcf of gas.

The estimates of oil and gas reserves were prepared by Company employees and do
not include proved undeveloped reserves attributable to either royalty interests
(information is not available) or outside operated working interests (quantities
are not considered significant to total Company proved reserves). Furthermore,
these estimates do not include reserves whose estimates or recoverability are
less precise, commonly referred to as "probable" or "possible" reserves. The
Company has no reserves outside the continental United States.

Standardized measure of discounted future net cash flows

In accordance with the requirements of Statement of Financial Accounting
Standards No. 69 ("SFAS No. 69") presented below are projections of future net
oil and gas cash flows (sales less production taxes, operating expenses, certain
development costs and estimated income taxes) and related present values of
proved oil and gas reserves. As required by SFAS No. 69, these projections are
based on end of period prices and costs, held constant for all future periods.
Present values of the future net oil and gas cash flows were calculated using a
10% discount factor as required. While this information was developed with
reasonable care and disclosed in good faith, it is emphasized that some of the
data are necessarily imprecise and represent only approximate amounts because of
the subjective judgments involved in developing such information. Accordingly,
this information may not represent the present financial condition of the
Company or its expected future results. This information does not include any
amounts applicable to "probable" or "possible" reserves which may become proved
in the future.

   SUPPLEMENTARY INFORMATION ON OIL AND GAS PRODUCING ACTIVITIES (unaudited)

Although these disclosures have been prepared in accordance with SFAS No. 69,
this information does not purport to present the fair market value of the
Company's oil and gas properties or a fair estimate of the present value of
future cash flows expected to be obtained from their production. The reserve
estimates, while carefully made, may be significantly revised based on future
events. In addition, estimates of the timing of production, actual prices
realized and related production costs and taxes may also vary significantly from
those used in these calculations.

Time ("HSRC Common Stock") shall, at the Effective Time, be converted into 48.66
shares of common stock, par value $0.01 per share, of HSOG ("New HSOG Common
Stock").  Each share of common stock, par value $20.00 per share, of HSOG which

virtue of the Merger and without further action be deemed cancelled. Each share
of HSRC Common Stock that shall at the Effective Time be held by HSOG or in the

          --------------------------------------                               
to HSRC that:

          (a)  HSOG is a corporation duly incorporated, validly existing and in
     good standing under the laws of the State of Oklahoma, and has all
     corporate powers and all governmental licenses, authorizations, consents
     and approvals required to carry on its business as now conducted.  HSOG is
     duly qualified to do business as a foreign corporation and is in good
     standing in each jurisdiction where the character of the property owned or
     leased by it or the nature of its activities makes such qualification
     necessary, except for those jurisdictions where the failure to be so
     qualified would not, individually or in the aggregate, have a material
     adverse effect on HSOG.

          (b)  The execution, delivery and performance by HSOG of this Agreement
     and the consummation by HSOG of the transactions contemplated hereby are
     within the corporate powers of HSOG and, except as set forth in the next
     sentence, have been duly authorized by all necessary corporate action.  The
     affirmative vote of the holders of 66 2/3 percent of the outstanding shares
     of Old HSOG Common Stock entitled to vote thereon is the only vote of any
     class or series of HSOG capital stock necessary to approve this Agreement
     and the transactions contemplated hereby. This Agreement constitutes a
     valid and binding agreement of HSOG, enforceable in accordance with its
     terms (except insofar as enforceability may be limited by applicable
     bankruptcy, insolvency, reorganization, moratorium or similar laws
     affecting creditors' rights generally, or by principles governing the
     availability of equitable remedies).

     8.   Representations and Warranties of HSRC.  HSRC represents and warrants
          --------------------------------------                               
to HSOG that:

          (a)  HSRC is a corporation duly incorporated, validly existing and in
     good standing under the laws of the State of Oklahoma and has all corporate
     powers and all governmental licenses, authorizations, consents and
     approvals required to carry on its business as now conducted.  HSRC is duly
     qualified to do business as a foreign corporation and is in good standing
     in each jurisdiction where the character of the property owned or leased by
     it or the nature of its activities makes such qualification necessary,
     except for those jurisdictions where the failure to be so qualified would
     not, individually or in the aggregate, have a material adverse effect on
     HSRC.

          (b)  The execution, delivery and performance by HSRC of this Agreement
     and the consummation by HSRC of the transactions contemplated hereby are
     within the corporate powers of HSRC and, except as set forth in the next
     sentence, have been duly authorized by all necessary corporate action.  The
     affirmative vote of the holders of 66 2/3 percent of the outstanding shares
     of HSRC Common Stock entitled to vote thereon is the only vote of any class
     or series of HSRC capital stock necessary to approve this Agreement and the
     transactions contemplated hereby. This Agreement constitutes a valid and
     binding agreement of HSRC, enforceable in accordance with its terms (except
     insofar as enforceability may be limited by applicable bankruptcy,
     insolvency, reorganization, moratorium or similar laws affecting creditors'
     rights generally, or by principles governing the availability of equitable
     remedies).

     body, agency, official, or authority required to permit the consummation of
     the Merger shall have been obtained, but excluding any consent, approval,
     clearance or confirmation the failure to obtain which could not reasonably
     be expected to have a material adverse effect on the Surviving Corporation
     after the Effective Time.

          (c)  HSOG and HSRC shall have obtained an opinion of Conner & Winters,
     A Professional Corporation, to the effect that (1) the Merger will qualify
     as a "reorganization" under Section 368(a) of the Code and the regulations
     thereunder, (2) each of HSOG and HSRC will be a party to such
     reorganization within the meaning of Section 368(b) of the Internal Revenue
     Code of 1986, as amended, and the regulations thereunder, (3) no gain or
     loss will be recognized by HSOG or HSRC as a result of the Merger, and (4)
     no gain or loss will be recognized by a stockholder of HSRC as a result of
     the Merger with respect to the shares of HSRC Common Stock converted solely
     into shares of New HSOG Common Stock.

          (d)  HSOG and HSRC shall have received from Principal Financial

     stockholders of HSOG and HSRC, and such opinion shall not have been
     withdrawn.

The obligation of HSOG to consummate the Merger is further subject to the
condition (unless waived by HSOG) that holders of not more than twelve percent
of either Old HSOG Common Stock or HSRC Common Stock shall have exercised their
right to appraisal pursuant to Section 1091 of the Act.

     10.  Filing of Certificate of Merger.  The Certificate of Merger shall be
          -------------------------------

Special Committee of the
  Board of Directors
Attn.: Mr. Ronald O. Gutman, Chairman 
The Home-Stake Royalty Corporation
15 East 5th Street, Suite 2800
Tulsa, OK 74103

Dear Special Committee:

   Principal Financial Securities, Inc. ("PFS") understands that The Home-Stake
Royalty Corporation ("HSRC" or the "Company"), will enter into a transaction
("Transaction") pursuant to an Agreement of Merger, dated August 14, 1997 (the
"Merger Agreement"), whereby all issued and outstanding shares of the Company's
Common Stock (including all options and warrants to purchase Common Stock) 
shall be cancelled and extinguished and each share shall be converted into the
right to receive 48.66 shares of The Home-Stake Oil & Gas Company ("HSOG", and
together with HSRC, the "Companies") common stock (the "Proposed Consideration")
after taking into account a 30-for-1 split of HSOG common stock. You have asked
us to advise you as to the fairness to the holders of the Company's Common Stock
other than directors, officers, employees or holders of 15 percent (15%) or more
of the Common Stock of the Company (the "Disinterested Shareholders") of the
Proposed Consideration.

   In arriving at our opinion we have:

   1.  Reviewed the Merger Agreement;

   2.  Reviewed HSOG's and HSRC's Forms 10-KSB for the fiscal year ended
       December 31, 1996 and financial results for the six month period ending
       June 30, 1997;

   3.  Reviewed certain internally prepared reserve information provided by the
       Companies relating to the producing properties of the Companies and
       audited by Lee Keeling and Associates, Inc.;

   4.  Reviewed certain other assets of the Companies including non-producing
       mineral interests and a valuation of such assets by an outside certified
       petroleum geologist;

   5.  Reviewed the Companies' projected financial and operating results
       including capitalization ratios, earnings, cash flow, book value and
       production;

The Home-Stake Royalty Corporation

   6.  Reviewed the financial terms, to the extent publicly available, of
       certain comparable reserve acquisition transactions;

   7.  Discussed with management of the Companies the operations of and business
       prospects for the Companies; and

   8.  Performed other analyses as are customary in our industry.

   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.  In the ordinary course of business, Principal
Financial Securities, 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 debt or equity securities or options on securities
of the Companies.

   In connection with our review, we have not independently verified any of the
information concerning the Companies and have relied on its being complete and
accurate in all material respects.  We have assumed that the pro forma financial
and reserve information reviewed by us has been reasonably prepared on bases
reflecting the best currently available estimates and judgments of the
Companies' management as to the future performance reflected therein.  In
addition, we have not made an independent evaluation or appraisal of the assets
of the Companies, nor have we been furnished with any such independent
evaluations or appraisals (other than an appraisal report of non-producing
minerals prepared by an outside certified petroleum geologist on behalf of the
Companies).

   Our opinion is necessarily based solely upon the information set forth herein
as reviewed by us and circumstances existing as of the date hereof.  Events
occurring after the date hereof could materially affect the assumptions used
both in preparing this opinion and in the documents reviewed by us.

   We are not opining, and were not requested by you to opine, as to the
fairness of any aspect of the Transaction other than the Proposed Consideration
to the disinterested stockholders of the Company.  We have assumed that the
Merger Agreement and all other aspects of the proposed Transaction will be, in
all respects, in compliance with all laws and regulations that are applicable to
HSRC, or the proposed Transaction (and we have relied as to all legal matters
relating thereto on counsel to HSRC).  We are not expressing any opinion as to
what the value of HSOG or HSRC Common Stock will be at the time of the Merger or
the prices at which the HSOG Common Stock will trade during the period following
announcement of the Merger or subsequent to the consummation of the Merger.
Further, our opinion does not address HSRC's or HSOG's underlying business
decisions effect on the Merger.

   This letter shall be for the use of the Special Committee of the Board of
Directors of the Company in considering the Transaction.  The Company may not
publish or refer to this letter

unreasonably withheld. It is expressly understood that this letter may be

mailed to the stockholders of the Company in connection with the Transaction, or

disclosures relating to PFS's engagement and the letter.

   Based upon and subject to the foregoing, including the various assumptions
and limitations set forth herein, it is our opinion that, on the date hereof,
the Proposed Consideration is fair to the Disinterested Shareholders of the
Company.

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 his 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.  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
Sections 1081, 1082, 1086, 1087, or 1091.1 of this title or Section 12 of this
act./1/


          2.  a.  No appraisal rights under this section shall be available for
                  the shares of any class or series of stock which, at the

                  receive notice of and to vote at the meeting of shareholders
                  to act upon the agreement of merger or consolidation, were
                  either:

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

              b.  In addition, 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
                  for in subsection F of Section 1081 of this title.

accept for such stock anything except:

              a.  shares of stock of the corporation surviving or resulting from
                  such merger or consolidation; or

              b.  shares of stock of any other corporation which at the
                  effective date of the merger or consolidation will be either

                  more than two thousand shareholders; or

              c.  cash in lieu of fractional shares of the corporations
                  described in subparagraphs a and b of this paragraph; or

              d.  any combination of the shares of stock and cash in lieu of the
                  fractional shares 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 such appraisal rights
that appraisal rights are available for any or all of the shares of the
constituent corporations, and shall include in such 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.  Such 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 such
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

          2.  If the merger or consolidation was approved pursuant to the
provisions of Section 1073 or 1083 of this title, the surviving or resulting
corporation, either before the effective date of the merger or consolidation or
within ten (10) days thereafter, shall notify each of the shareholders entitled
to appraisal rights of the effective date of the merger or consolidation and
that appraisal rights are available for any or all of the shares of the
constituent corporation, and shall include in such notice a copy of this
section.  The notice shall be sent by certified or registered mail, return
receipt requested, addressed to the shareholder at the address of the
shareholder as it appears on the records of the corporation.  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 shares of the shareholder.  Such 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
shares of the shareholder.

     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, 

                                      C-2
<PAGE>
 
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 such shares. Such written statement shall
be mailed to the shareholder within ten (10) days after the shareholder's
written request for such 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 such 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 payment for their shares and with whom agreements as to 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 a duly verified list.  The court clerk, if
so ordered by the court, shall give notice of the time and place fixed for the
hearing of such 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.  Such 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 such
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 such 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 for 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 such direction, the court may dismiss the
proceedings as to such 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 such 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 such is 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 so made to each such 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 such stock.  The court's decree may be enforced as
other decrees in the district court may be enforced, whether such surviving or
resulting corporation be a corporation of this state or of any other state.

                                      C-3
<PAGE>
 
     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 the appraisal rights of the shareholder as
provided for in subsection D of this section shall be entitled to vote such
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 such
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
such shareholder to an appraisal shall cease.  Provided, however, no appraisal
proceeding in the district court shall be dismissed as to any shareholder
without the approval of the court, and such approval may be conditioned upon
such terms as the court deems just.

     L.   The shares of the surviving or resulting corporation into which the
shares of such 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

/1/  Section 1090.2 of this title.

           ----- -- ------------ 

           (a)   Governing Law.  The construction and operation of the Plan are
                 --------- ---

                 --------- -----                                       
     any term not specifically defined in the Plan has the meaning given to it

           (c)   Headings.  All headings in the Plan are for reference only and

                                        ---- ----- 

           (f)   Severability.  If any provision of the Plan is determined to be
                 ------------                                                   
     illegal or invalid for any reason, the remaining provisions shall continue
     in full force and effect and shall be construed and enforced as if the
     illegal or invalid provision did not exist, unless the continuance of the
     Plan in such circumstances is not consistent with its purposes.

3.   Stock Subject to the Plan.
     ----- ------- -- --- ---- 


Four Hundred Fifty-One Thousand Seven Hundred and Thirty-Six (451,736) shares of
HSOG's Common Stock (or such greater or lesser number of shares that equals ten

to Options granted under this Plan and any other stock plan(s) of the Company
equals ten percent (10%) of the issued and outstanding shares of Common Stock at
such time(s) after the effective date of the Stock Split as the Company issues

powers set forth in the Plan, the Board has the exclusive authority:

        (a) to construe and interpret the Plan, and to remedy any ambiguities or
     inconsistencies therein;

                                      F-4
<PAGE>
 
        (b) to establish, amend and rescind appropriate rules and regulations
     relating to the Plan;

     each Award and the Option Price, payment terms, payment method, and
     expiration date applicable to each Award;

     HSOG, any ruling or decision on any matter relating to the Plan or to any
     Awards of Options and/or Restricted Stock;

        (e) generally, to administer the Plan, and to take all such steps and
     make all such determinations in connection with the Plan and the Awards of
     Options and/or Restricted Stock as it may deem necessary or advisable;

        (f) to determine the form in which tax withholding under Section 14 of
     the Plan will be made; and

        (g) to amend the Plan or any Option or Restricted Stock granted or

5.   Eligible Participants.
     -------- ------------ 

     Subject to the provisions of the Plan, the persons who shall be eligible to
participate in the Plan and be granted Awards shall be those persons who are
Officers, Directors, key employees and consultants of HSOG or any Subsidiary who
shall be in a position, in the opinion of the Board, to make contributions to
the growth, management, protection, and success of HSOG and its Subsidiaries.
Of those persons described in the preceding sentence, the Board may, from time
to time, select persons to be granted Awards and shall determine the terms and
conditions with respect thereto.  In making any such selection and in
determining the form of the Award, the Board may give consideration to the
functions and responsibilities of the person, to the person's contributions to
HSOG and its Subsidiaries, the value of the individual's service to HSOG and its
Subsidiaries and such other factors deemed relevant by the Board.  In the event
and to the extent authorized by the United States Departments of Treasury and
Labor, The Home-Stake Companies 401(k) Plan account of an employee of HSOG or a
Subsidiary may also be a Participant, the Board may grant Options to such
account and, to the extent such account is a Participant, the Options in such an
account shall be subject to all of the terms and provisions of the Plan as if
the Options had been granted to the individual for whom the account is
maintained.

6.   Terms and Conditions of Options.
     ----- --- ---------- -- ------- 

     The Board may, in its discretion, grant Options to any Participant under
the Plan.  Each Option shall be evidenced by a written agreement between HSOG
and the Participant. Unless the Board at the time of grant specifically
designates Options granted under the Plan as Incentive Stock Options, all
Options granted under the Plan shall be non-statutory options. Each Option
agreement, in such form as is approved by the Board, shall be subject to the
following express terms and conditions and to such other terms and conditions,
not inconsistent with the Plan as the Board may deem appropriate:

        (a) Option Period.  Each Option granted under the Plan shall be for such
            ------ ------                                                       
     period as is established by the Board, except that each ISO shall expire no
     later than ten years after the Option Date.  Where Options are exercisable
     in installments, the right to purchase any shares shall be cumulative, so
     that when the right to purchase any shares has matured, such shares may be
     purchased thereafter until the expiration of the Option.  The Board shall
     have the power to accelerate the exercisability of installments for any
     Option granted under the Plan.

                                      F-5
<PAGE>
 
        (b) Option Price.  At the time when the Option is granted, the Board 
            ------ -----      
     will fix the Option Price; provided, however, that except as provided
     herein at Section 6(c)(i), the Option Price shall be no less than the Fair
     Market Value on the Option Date.

        (c) Other Option Provisions.  The form of Option authorized by the Plan
            ------ ------ ---------                                            
     may contain such other provisions as the Board may from time to time
     determine, including:

            (i)   "Discounted Options" which may be granted to any Participant.
            A "Discounted Option" is an Option having an Option Price per share
            (i) less than the Fair Market Value at the Option Date provided such
            Option Price shall not be less than 50% of the Fair Market Value at
            the Option Date, or (ii) in the case of Directors, equal to the Fair
            Market Value at the Option Date, less the amount of salary or
            Director's fees elected (at least six months before the commencement
            of the calendar or fiscal year with respect to which such fees will
            be earned) by a Director to be received in the form of Options (the
            "deferred amount") divided by the number of shares subject to the
            Option. Discounted Options shall not be forfeitable under any
            provision of the Plan and shall be exercisable until the third
            anniversary of the Participant's Termination of Employment;

            (ii)  "Reload Options" which may be granted only to Directors and
            employees of HSOG or a Subsidiary. A "Reload Option" is an Option
            automatically granted to a Participant pursuant to the terms of an
            Award Agreement upon the delivery (actual, constructive or by
            attestation) of shares of Common Stock to pay any required
            withholding tax in respect of the exercise of an Option (the
            "delivered shares"). Such Reload Option entitles the Participant to
            purchase (at an option price equal to the Fair Market Value at the
            time of such delivery) a number of shares of Common Stock equal to
            the number of delivered shares. Reload Options shall be subject to
            all of the terms of the Plan and the Award Agreement in respect to
            which they are granted, including the Option Period for the Option
            exercised by delivery of the delivered shares, and shall not be
            exercisable before the earlier of one year after their grant or the
            day before the expiration of such Option Period. In the discretion
            of the Board, Reload Options granted on the exercise of ISO's may be
            ISO's or non-qualified options.

            (d) Incentive Stock Options. ISO's may only be granted to employees 
                --------- ----- -------                              
     of HSOG or of a Subsidiary. No more than Four Hundred Fifty-One Thousand
     Seven Hundred and Thirty-Six (451,736) shares of HSOG's Common Stock (as
     adjusted to reflect the Stock Split) may be issued upon the exercise of
     ISO's granted under this Plan and no ISO may be granted under the Plan
     after the tenth anniversary of the date the Plan is approved by the
     shareholders of HSOG. The aggregate Fair Market Value (determined as of the
     Option Date of the ISO) of the Common Stock with respect to which ISO's are
     first exercisable by a Company or Subsidiary employee during any calendar
     year under all Option plans of HSOG shall not exceed $100,000. An ISO
     granted to an employee who, at the time the ISO is granted, owns Common
     Stock possessing more than ten percent (10%) of the total combined voting
     power of all classes of capital stock of HSOG or a Subsidiary thereof shall
     have an exercise price equal to not less than 110 percent (110%) of the
     Fair Market Value on the Option Date. Notwithstanding any other provision
     of this Plan, an ISO shall not be transferable or assignable otherwise than
     by will or the laws of descent and distribution. Any Participant who
     disposes of shares acquired upon the exercise of an ISO either (i) within
     two years after the Option Date of the Option under which the shares were
     acquired or (ii) within one year after the acquisition of such shares shall
     notify HSOG of such disposition and of the amount realized. Failure by a
     Participant to so notify HSOG of such a disposition of shares shall entitle
     HSOG to treat the shares of Common Stock issued to such Participant as void
     ab initio or to recover from the Participant the greater of the value of
     the shares disposed of as of the date of disposition or the value of the
     shares disposed of as of the date HSOG learns of such disposition from
     either (ii) any amounts due to such Participant from HSOG or a Subsidiary,
     or (ii) otherwise. HSOG may, at its discretion, place a legend noting the
     possible consequences of a Participant's failure to provide such
     disposition notice on shares of Common Stock delivered upon the exercise of
     an ISO.

                                      F-6
<PAGE>
 
          (e) No person shall have any rights of a shareholder with respect to
     any shares to be delivered upon the exercise of an Option until such time
     as such Option is validly exercised.

7.   Terms and Conditions of Restricted Stock Awards.
     ----------------------------------------------- 

     The Board, in its discretion, may grant Restricted Stock to any Participant
under the Plan, the purchase price of which shall be established by the Board,
which purchase price may be financed by HSOG on terms established by the Board.
Each grant of Restricted Stock shall be evidenced by an Award Agreement between
HSOG and the Participant.  All shares of Common Stock awarded to Participants
under the Plan as Restricted Stock shall be subject to the following express
terms and conditions and to such other terms and conditions, not inconsistent
with the Plan, as the Board shall deem appropriate:
 
          (a)    Restrictions on Transfer.  Shares of Restricted Stock awarded 
                 ------------------------   
     to Participants shall contain such restrictions on transfer as the Board
     may determine in its sole discretion. Except as permitted under Section 12
     of the Plan, shares of Restricted Stock awarded to Participants may not be
     sold or transferred before such restrictions on transfer lapse, and may
     only be pledged to HSOG or any Subsidiary to satisfy any obligations that
     the Participant may have to HSOG or the Subsidiary with respect to the
     acquisition of such shares of Restricted Stock. Subject to the provisions
     of subparagraphs (b) and (c) below and any other restrictions imposed by
     law, the certificates for any shares of Restricted Stock the restrictions
     on which have lapsed will be transferred to the Participant or, in the
     event of his death, to the beneficiary or beneficiaries designated by
     writing filed by the Participant with the Board for such purpose or, if
     none, to his estate. Delivery of shares in accordance with the preceding
     sentence shall be made within the 30-day period after such restrictions
     shall lapse.

          (b)    Certificates Deposited With Company.  Each certificate issued 
                 -----------------------------------   
     in respect of shares of Restricted Stock awarded under the Plan shall be
     registered in the name of the Participant and deposited with HSOG. Each
     such certificate shall bear the following (or a similar) legend:

          "The transferability of this certificate and the shares of stock
          represented hereby are subject to the terms and conditions (including
          forfeiture) relating to Restricted Stock contained in The Home-Stake
          Oil & Gas Company 1997 Incentive Stock Plan and an agreement entered
          into between the registered owner and The Home-Stake Oil & Gas
          Company. Copies of such Plan and agreement are on file at the
          principal office of The Home-Stake Oil & Gas Company."

          (c)    Shareholder Rights.  Subject to the foregoing restrictions, 
                 ------------------   
     each Participant shall have all the rights of a shareholder with respect to
     his shares of Restricted Stock including, but not limited to, the right to
     vote such shares.

          (d)    Dividends.  On each Common Stock dividend payment date, each
                 ---------                                                   
     Participant shall receive an amount equal to the dividend paid on that date
     on a share of Common Stock, multiplied by his number of shares of
     Restricted Stock.

8.   Manner of Exercise of Options; Deferral of Receipt of Shares.
     ------------------------------------------------------------ 

          (a)    To exercise an Option in whole or in part, a Participant (or,
     after his death, his executor or administrator) or his assignee (as
     contemplated at Section 12 hereof) must give written notice to the
     Administrator, stating the number of shares with respect to which he
     intends to exercise the Option.  HSOG will issue the shares with respect to
     which the Option is exercised upon payment in full of the Option Price. The
     Option Price may be paid (i) in cash, (ii) in shares of Common Stock held
     by the Participant, his executor, administrator, or assignee, and having an
     aggregate Fair Market Value, as determined  as of the close of business on
     the day on which such Option is exercised, 

                                      F-7
<PAGE>
 
     equal to the Option Price, (iii) if permitted by the Board, a promissory
     note in the amount of the Option Price, which note shall provide for full
     personal liability of the maker and shall contain such other terms and
     provisions as the Board may determine, including without limitation the
     right to repay the note partially or wholly with Common Stock, (iv) if
     authorized by the Board in the Award Agreement for the Option being
     exercised, by delivery of irrevocable instructions to a broker to promptly
     deliver to HSOG the amount of sale or loan proceeds necessary to pay for
     all Common Stock acquired through such exercise and any tax withholding
     obligations resulting from such exercise, (v) if authorized by the Board in
     the Award Agreement for the Option being exercised, by the withholding by
     HSOG, pursuant to a written election delivered by the Participant, his
     executor, administrator, or assignee, to the Administrator on or prior to
     the date of exercise, from the shares of Common Stock issuable upon any
     exercise of the Option that number of shares having a Fair Market Value as
     of the close of business on the day on which such Option is exercised equal
     to such Option Price, (vi) by constructive delivery ("attestation") of
     shares of Common Stock held by the Participant, his executor,
     administrator, or assignee, and having an aggregate Fair Market Value, as
     determined as of the close of business on the day of exercise, equal to the
     Option Price effected through providing HSOG with a notarized statement on
     or before the day of exercise attesting to the number of shares owned by
     the Participant, his executor, administrator, or assignee, that will serve
     as the Option Price payment shares, or (vii) as authorized by the Board in
     the Award Agreement for the Option being exercised, by a combination of
     such methods. The Option Price may also be paid in shares of Common Stock
     which were received by the Participant, his executor, administrator, or
     assignee, upon the exercise of one or more Options or as an award of
     Restricted Stock under the Plan; provided, however, that in the event
     shares of Restricted Stock are tendered as consideration for the exercise
     of an Option, a number of the shares issued upon the exercise of said
     Option, equal to the number of shares of Restricted Stock used as
     consideration therefor, shall be subject to the same restrictions as the
     Restricted Stock so submitted were at the time of their submission plus any
     additional restrictions that may be imposed by the Board.

          (b)    A Participant (but not his executor, administrator or assignee)
     may elect to defer the receipt of a portion of the shares of Common Stock
     (the "Deferred Shares") deliverable upon the exercise of a non-qualified
     Option provided such Participant (i) delivers to the Board a written
     election (a "Deferral Election") to defer the receipt of shares of Common
     Stock, in such form and with such terms as the Board determines, no later
     than six months before the date of exercise of an Option as to which the
     receipt of a portion of the shares of Common Stock is to be deferred, (ii)
     pays the Option Price payable upon such exercise by delivery, or by
     attestation, to HSOG of shares of Common Stock as provided at Section 8(a)
     hereof, and (iii) is employed by HSOG or a Subsidiary at the time of
     exercise of such Option. Only the number of shares otherwise deliverable
     upon exercise of a non-qualified Option in excess of the number of shares
     of Common Stock delivered in payment of the Option Price upon any exercise
     of such Option shall be Deferred Shares. Any such Deferral Election shall
     be revocable only upon the delivery of a superseding Deferral Election for
     the shares subject to a Deferral Election. Upon the exercise of an Option
     subject to a Deferral Election, that number of shares of Common Stock
     which, but for such Deferral Election, would be deliverable upon such
     exercise shall be issued to HSOG for the benefit of the Participant and
     credited to a bookkeeping account (a "Unit Account") in the name of the
     Participant. Each Participant's Unit Account will be credited with all non-
     cash property either distributed in respect of any Deferred Shares,
     credited to such account or into which any Deferred Shares credited to such
     Unit Account are converted. All cash distributed in respect of a
     Participant's Deferred Shares or into which a Participant's Deferred Shares
     are converted shall be delivered to such Participant as soon as is
     reasonably practical after such distribution or conversion. No Participant
     shall be entitled to vote the Deferred Shares and instead such shares shall
     be voted by the Secretary of HSOG on behalf of such Participant on all
     matters on which the holders of Common Stock are entitled to vote in the
     same manner as a majority of the shares of Common Stock are voted.

9.   Vesting.
     ------- 

                                      F-8
<PAGE>
 
     A Participant may not exercise an Option until it has become vested.  The
portion of an Option Award that is vested depends upon the vesting restrictions,
if any, established by the Board for such Option at the time of its grant and
the period that has elapsed since the Option Date.

10.  Change in Control.
     ----------------- 

     Notwithstanding the provisions of Sections 6 and 7 or anything contained in
a Participant's agreement to the contrary, upon a Change in Control, all Options
and/or Restricted Stock shall be subject to the following:

          (a)    The restrictions and limitations applicable to any Options
     shall lapse, and such Options shall become free of all restrictions and
     become fully vested to the full extent of the original grant.
 
          (b)    HSOG shall have the right to acquire from Participants their
     vested Options for which the value, as established in the Change in
     Control, of the Common Stock issuable upon exercise thereof is greater than
     the Option Price by payment of the amount by which the price per share of
     Common Stock, as established in the Change in Control, exceeds the Option
     Price; and

          (c)    All Restricted Stock shall become free of all restrictions and
     be fully vested and transferable.

11.  Adjustments to Reflect Changes in Capital Structure.
     --------------------------------------------------- 

     If there is any change in the corporate structure or shares of HSOG, the
Board of Directors may, in its discretion, make any adjustments necessary to
prevent accretion, or to protect against dilution, in the number and kind of
shares authorized by the Plan and, with respect to outstanding Options and/or
Restricted Stock, in the number and kind of shares covered thereby and in the
applicable Option Price. For the purpose of this Section 11, a change in the
corporate structure or shares of HSOG includes, without limitation, any change
resulting from a recapitalization, stock split, stock dividend, consolidation,
rights offering, spin-off, reorganization, or liquidation and any transaction in
which shares of Common Stock are changed into or exchanged for a different
number or kind of shares of stock or other securities of HSOG or another
corporation.

12.  Non-Transferability of Options and Restricted Stock; Limited Exception to
     -------------------------------------------------------------------------
     Transfer Restrictions.
     --------------------- 

          (a)    Unless otherwise expressly provided in this Section 12, by
     applicable law or by any Award Agreement, as the same may be amended,
     evidencing the grant or award of Restricted Stock or Options:  Awards are
     non-transferable and shall not be subject in any manner to sale, transfer,
     anticipation, alienation, assignment, pledge, encumbrance or charge; Awards
     shall be exercised only by the person to whom such Awards were granted or
     awarded (a "Recipient"); and amounts payable or shares issuable pursuant to
     Awards shall be delivered only to or for the account of a Recipient.

          (b)    Except as precluded by any applicable law, the Board may permit
     Awards to be transferred to and exercised by and paid to certain persons or
     entities related to the Recipient, including, but not limited to members of
     the Recipient's immediate family (parents, grandparents, children,
     grandchildren, spouse, siblings), charitable institutions, or trusts or
     other entities whose beneficiaries or beneficial owners are members of the
     Recipient's immediate family and/or charitable institutions, or to such
     other persons or entities as may be approved by the Board, pursuant to such
     conditions and procedures as the Board may establish.  Any permitted
     transfer shall be subject to the condition that the Board receive evidence
     satisfactory to it that the transfer is being made for estate and/or tax
     planning purposes on a gratuitous or donative basis and without
     consideration other than nominal consideration.

                                      F-9
<PAGE>
 
          (c)    The exercise and transfer restrictions in this Section 12 shall
     not apply to:

                 (i)    transfers to HSOG;

                 (ii)   the designation of a beneficiary to receive benefits in
          the event of the Recipient's death or, if the Recipient has died,
          transfers to or exercise by the Recipient's beneficiary, or, in the
          absence of a validly designated beneficiary, transfers by will or the
          laws of descent and distribution;

                 (iii)  transfers pursuant to a domestic relations order;

                 (iv)   if the Recipient has suffered a disability, permitted
          transfers or exercises on behalf of the Recipient by his or her legal
          representative; or

                 (v)    the authorization by the Board of "cashless exercise"
          procedures with third parties who provide financing for the purpose of
          (or who otherwise facilitate) the exercise of Awards consistent with
          applicable laws and the express authorization of the Board.

          (d)    In the event of a transfer of an Award pursuant to Subsection
     (b) or (c) of this Section 12, the Recipient will remain liable for any
     taxes (including withholding and social security taxes) due upon or as a
     consequence of the exercise of or lapse of any restrictions in respect of
     an Award and neither HSOG nor the Board shall have any obligation to
     provide notice to a transferee of any event or information that has, will
     or could in any way affect an Award or its exercise.

13.  Rights as Shareholder.
     --------------------- 
 
     No person shall have any rights of a shareholder as to shares of Common
Stock subject to an Award under the Plan until, after proper exercise of the
Award or other action required, such shares shall have been recorded on HSOG's
official shareholder records as having been issued or transferred.  Upon
exercise of the Award or any portion thereof, HSOG will have thirty (30) days in
which to issue the shares, and the Participant will not be treated as a
shareholder for any purpose whatsoever prior to such issuance.  No adjustment
shall be made for cash dividends or other rights for which the record date is
prior to the date such shares are recorded as issued or transferred in HSOG's
official shareholder records, except as provided herein or in an Agreement.

14.  Withholding Tax.
     --------------- 

     Upon the exercise of an Option, or the lapse of restrictions on Restricted
Stock, requiring tax withholding, the Participant will be required to pay to
HSOG for remittance to the appropriate taxing authorities an amount necessary to
satisfy the employee's portion of federal, state and local taxes, if any,
incurred by reason of the exercise of an Option or the lapse of such
restrictions.  A Participant may elect to have any tax withholding obligation
incurred upon the exercise of or lapse of restrictions in respect of an Award
satisfied by payment of cash by the Participant, by the withholding of cash
otherwise due the Participant, or, except in the case of ISO's, by the
withholding of shares of Common Stock issuable upon such occurrence and having
an aggregate Fair Market Value on the day prior to the day of exercise or lapse
sufficient to satisfy the applicable tax withholding requirement; provided,
however, that if the Participant elects to have shares of Common Stock withheld
from the shares deliverable upon such exercise or lapse, a Participant's
election must be delivered to the Administrator in writing on or prior to the
date of exercise of the Options or lapse of restrictions with respect to
Restricted Stock.

15.  Termination of Employment.
     ------------------------- 

     In the event of a Participant's Termination of Employment, the following
rules shall apply:

                                      F-10
<PAGE>
 
           (a)   Resignation in order to assume employment, approved by HSOG's
     Chief Executive Officer, with a governmental, charitable or educational
     institution, or business entity affiliated with HSOG:

           When a Participant resigns to assume employment, approved by HSOG's
     Chief Executive Officer, with a governmental, charitable or educational
     institution, or business entity in which HSOG has an equity interest, the
     Board may (i) authorize the continuation of Options granted or Restricted
     Stock awarded prior to termination as if the Participant were still
     employed by HSOG and (ii) permit the exercise of such Options or lapse of
     restrictions in respect of Restricted Stock during periods after such
     Termination of Employment, but not beyond the original expiration date of
     the Option.  Such actions will not be authorized to the extent they would
     cause outstanding ISOs to be considered to have been modified for purposes
     of Section 424(h) of the Code.  Unless the Board determines otherwise,
     termination of such approved employment, except to rejoin HSOG or accept
     other employment which would qualify under this paragraph (a), or
     divestiture by HSOG of its equity interest in such business entity, shall
     be treated as a termination of employment pursuant to paragraph (b), (c) or
     (d) of this Section 15.

           (b)   Termination of Employment for any reason other than death,
     disability or resignation for approved employment pursuant to paragraph (a)
     above:

           Any Option or Restricted Stock shall expire forthwith; provided,
     however, that with the approval of the Board evidenced by a writing signed
     by an executive officer of HSOG other than the Participant, unvested
     Options may be accelerated to vest immediately, any Options exercisable at
     the time of such termination may be exercised up to a date after such
     termination that is determined by the Board, but not exceeding five years
     from the date of such termination and not beyond the date the Option
     otherwise would have expired in accordance with the Award Agreement
     evidencing such Option and/or the restrictions on Restricted Stock may be
     eliminated so that such Restricted Stock is free of such restrictions at
     the time of Termination of Employment and not forfeited upon such
     Termination of Employment.
 
           (c)   Death of a Participant:

           A Participant's estate or beneficiaries shall have a period up to the
     later of one year after the Participant's death or the expiration date
     specified in the Award Agreement within which to exercise the Option;
     provided, however, in the case of ISO's, the Participant's estate or
     beneficiaries may exercise an Option only until the expiration date
     specified in the Award Agreement.  Any Option may be immediately exercised
     in full by the Participant's estate or beneficiaries.  In the event the
     Participant's estate is closed with exercisable Options then unexercised,
     the rights under this paragraph shall pass by will or the laws of descent
     and distribution.  In the case of Restricted Stock, the restrictions on
     such Restricted Stock shall be deemed to have lapsed immediately before
     such Participant's death.

           (d)   Disability of a Participant:

           In the event of a Participant's Disability during employment, the
     Participant, or his or her guardian or legal representative shall have a
     period up to the expiration date specified in the Award Agreement within
     which to exercise the Option.  In the case of Restricted Stock, the
     restrictions on such Restricted Stock shall be deemed to have lapsed
     immediately before the Termination of Employment of such Participant.

16.  Cancellation of Option Grants and Restricted Stock.
     -------------------------------------------------- 

           (a)   After Termination of Employment.  If there is a Termination of
                 -------------------------------                               
     Employment with respect to a Participant for any reason other than death,
     and, pursuant to paragraph (a), (b) or (d) of 

                                      F-11
<PAGE>
 
     Section 15, one or more Options have not yet expired or the restrictions
     pertaining to Restricted Stock have not lapsed, the Board, in its sole
     discretion, which may be delegated to the Chief Executive Officer of HSOG
     or to the Chairman of the Board, may cancel any such Options at any time
     prior to the exercise thereof or declare forfeited any such Restricted
     Stock before the related restrictions lapse unless the following conditions
     are met:

                 (i)    The Participant shall not render services for any
           organization or engage directly or indirectly in any business which,
           in the judgment of the Chief Executive Officer of HSOG, is or becomes
           competitive with HSOG, or which is or becomes otherwise prejudicial
           to or in conflict with the interests of HSOG. The judgment of the
           Chief Executive Officer shall be based on the Participant's positions
           and responsibilities while employed by HSOG, the Participant's post-
           employment responsibilities and position with the other organization
           or business, the extent of past, current and potential competition or
           conflict between HSOG and the other organization or business, the
           effect on HSOG's customers, suppliers and competitors of the
           Participant's assuming the post-employment position, and such other
           considerations as are deemed relevant given the applicable facts and
           circumstances. The Participant shall be free, however, to purchase as
           an investment or otherwise, stock or other securities of such
           organization or business so long as such stock or securities are
           listed upon a recognized securities exchange or traded over-the-
           counter, and such investment does not represent a substantial
           investment to the Participant or a greater than five percent (5%)
           equity interest in the organization or business.

                 (ii)   The Participant shall not, without prior written
           authorization from HSOG, disclose to anyone outside HSOG, or use in
           other than HSOG's business, any confidential information or material
           relating to the business of HSOG, acquired by the Participant either
           prior to or after such Participant's Termination of Employment.

           (b)   Before Termination of Employment.  The Board, in its sole
                 --------------------------------                         
     discretion, which may be delegated to the Chief Executive Officer of HSOG
     or to the Chairman of the Board, may cancel any Options held by a person or
     reduce the number thereof at any time prior to the exercise thereof or
     declare forfeited a part or all of any shares of Restricted Stock awarded
     to a Participant under the following circumstances:

                 (i)    The Participant's conduct either in connection with his
           or her employment by HSOG or otherwise is deemed inimical to the
           interests of HSOG.

                 (ii)   The Participant's employment responsibilities with HSOG
           are reduced or altered and the Board determines that the Participant
           would not have been granted the Options or awarded the shares of
           Restricted Stock, or such number of Options or shares of Restricted
           Stock, had the Participant's employment responsibilities been at the
           reduced or altered level at the time of the grant or award of such
           Options or shares of Restricted Stock.

17.  No Right To Employment.
     ---------------------- 

     Participation in the Plan will not give any Participant a right to be
retained as an employee of HSOG or any Subsidiary, or any right or claim to any
benefit under the Plan, unless the right or claim has specifically accrued under
the Plan.

18.  Amendment of the Plan.
     --------------------- 

     Except as provided in this Section 18, the Board of Directors may amend,
modify, suspend or discontinue this Plan for the purpose of meeting any changes
in legal requirements or for any other purpose permitted by law.  Except for any
adjustments pursuant to Section 11, the Board of Directors may not (a) increase
the maximum number of shares that may be issued under the Plan, except with the
approval of 

                                      F-12
<PAGE>
 
the shareholders of HSOG, (b) decrease the exercise price with respect to any
Option previously granted, or (c) delegate the administration of this Plan to
any committee.The Board may from time to time amend or revise the terms of the
Plan in whole or in part and may without limitation, adopt any amendment deemed
necessary.

19.  Notice.
     ------ 

     Any written notice to HSOG required by any of the provisions of the Plan
shall be addressed to the Administrator, if so required under the Plan, and
otherwise to the Chairman of the Board or to the Chief Executive Officer of
HSOG, and shall become effective when it is received by the office of such
Administrator, Chairman or the Chief Executive Officer.

20.  Company Benefit and Compensation Plans.
     -------------------------------------- 

     Nothing contained in the Plan shall prevent any Participant prior to death,
or the Participant's dependents or beneficiaries after the Participant's death,
from receiving, in addition to any Options or Restricted Stock provided for
under the Plan, any salary, incentive or performance plan Awards, payments under
a Company retirement plan or other benefits that may be otherwise payable or
distributable to such Participant, or to the Participant's dependents or
beneficiaries under any other plan or policy of HSOG or otherwise.  To the
extent permitted by law, grants of Options or awards of Restricted Stock under
the Plan may be made in combination with, or as alternatives to, grants, awards
or payments under other Company plans.

21.  Representations and Warranties.
     ------------------------------ 

     No person shall at any time have a right to be selected as a Participant in
the Plan, nor having been selected as a Participant for one Award to be selected
as a Participant for any other Award, and no person shall have any authority to
enter into any agreement assuring such selection or making any warranty or
representation with respect thereto.  A Participant shall have no rights to or
interest in any Option or Restricted Stock except as set forth herein.

22.  Unfunded Plan.
     ------------- 

     Insofar as it provides for grants of Options and awards of Restricted
Stock, the Plan shall be unfunded.  Although bookkeeping accounts may be
established with respect to Participants who are or may become entitled to
Common Stock under the Plan, any such accounts shall be used merely as a
bookkeeping convenience.  HSOG shall not be required to segregate any assets
that may at any time be represented by Common Stock, nor shall the Plan be
construed as providing for such segregation, nor shall HSOG nor the Board be
deemed to be a trustee of any Common Stock issuable or deliverable under the
Plan.  Any liability of HSOG to a Participant with respect to a grant of Options
or award of Restricted Stock under the Plan shall be based solely upon any
contractual obligations that may be created by the Plan or an Award Agreement;
no such obligation of HSOG shall be deemed to be secured by any pledge or other
encumbrance on any property of HSOG.  Neither HSOG nor the Board shall be
required to give any security or bond for the performance of any obligation that
may be created by the Plan.

23.  Shareholder Approval.
     -------------------- 

     Continuance of the Plan, and the validity of any Options granted or
Restricted Stock awarded under the Plan, shall be subject to approval by the
shareholders of HSOG of the Plan within 12 months after the date the Plan is
adopted by the Board.

24.  Conditions Upon Issuance of Shares.
     ---------------------------------- 

                                      F-13
<PAGE>
 
     An Option shall not be exercisable, a share of Common Stock shall not be
issued pursuant to the exercise of an Option, and restrictions on Restricted
Stock awarded shall not lapse until such time as the Plan has been approved by
the shareholders of HSOG and unless the Award of Restricted Stock, exercise of
such Option and the issuance and delivery of such share pursuant thereto shall
comply with all relevant provisions of law, including, without limitation, the
Securities Act, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange upon which the shares of
Common Stock may then be listed, and shall be further subject to the approval of
counsel for HSOG with respect to such compliance.  As a condition to the
exercise of an Option, HSOG may require the person exercising such Option to
represent and warrant at the time of any such exercise that the Common Stock is
being purchased only for investment and without any present intention to sell or
distribute such shares if, in the opinion of counsel for HSOG, such a
representation is required by any of the aforementioned relevant provisions of
law.

25.  Effective Date and Termination of Plan.
     -------------------------------------- 

     25.1  Effective Date.  The Plan is effective as of the of the date of its
           --------------                                                     
adoption by the Board of Directors, subject to its approval by the shareholders
of HSOG, pursuant to Section 23.

     25.2  Termination of the Plan.  The Board may terminate the Plan at any 
           -----------------------   
time with respect to any shares that are not then subject to Options or
Restricted Stock. Termination of the Plan will not affect the rights and
obligations of any Participant with respect to Options or Restricted Stock
awarded before termination.

                                                                      APPENDIX G

(S) 1.159.  Procedure by dissenting shareholder

     In case any shareholder of any domestic corporation lawfully elects to
exercise his right to dissent, the following procedure shall be followed:

     (1)   Such shareholder shall, at the meeting at which such proposed
corporate action is to be voted upon or at any time prior to such meeting,
submit to the president or secretary of the corporation, or to the officer in
charge of the registered office, a written objection to such corporate action
setting out that his right to dissent shall be exercised if such action be
approved by the shareholders' vote and giving his address to which notice
thereof shall be delivered or mailed in the event of such approval;

     (2)   If such corporate action be approved by such vote, such shareholder
shall, within twenty (20) days from the receipt of notice of such approval,
present or mail to the president or secretary, or to the officer in charge of
the registered office, a written demand that the corporation pay him the fair
value of his shares.  Such demand shall state the number and class of shares
upon which he is demanding payment, and the estimated fair value of such shares,
and shall contain a request that, in case the corporation shall not consent to
pay such estimated fair value, the corporation shall give notice of the amount
it claims to be the fair value thereof.  The fair value of such shares shall be
the market value thereof as of the day before the vote was taken authorizing
such corporate action, excluding any appreciation or depreciation in consequence
of such proposed action.  If such shares be listed upon a recognized stock
exchange and any of such shares shall have been sold upon such exchange upon the
day aforesaid, the fair value thereof shall be presumed to be the highest price
at which such shares were thus sold upon such day in the absence of any evidence
of fraud or collusion;

     (3)   Such shareholder shall, within such twenty-day period, submit to the
corporation or to one of the aforementioned officers thereof his certificate or
certificates of shares upon which he is demanding payment;

     (4)   Such certificates of shares shall be stamped or endorsed with a
statement or legend that such shares are dissenting shares, and a record thereof
shall be made upon the share ledgers of the corporation.  Upon all subsequent
transfers of such shares upon the books of the corporation, prior to the time
the price equal to such fair value has been paid to such dissenting
shareholders, the new certificates issued representing such shares shall bear a
like statement or legend together with the name and address of the original
dissenting holder thereof.  Such stamp or endorsement shall not in any way
constitute a waiver by the corporation of any right arising from the failure of
such shareholder to comply with the terms of this act;

     (5)   The corporation shall, within ten (10) days after receipt of the
demand provided for in paragraph (2) hereof, given written notice to such
dissenting shareholder at the address specified for such notice in such demand,
or, in the absence of such address in such demand, such notice shall be given to
such shareholder personally or mailed to the address at which notice of
shareholder's meetings are required to be mailed. Such notice shall either set
out that the corporation accepts the amount claimed in such demand and agrees to
pay such amount within fifteen (15) days upon the surrender of the share
certificates duly endorsed or contain an estimate by the corporation of the fair
value of such shares together with an offer to pay the amount of such estimate
within fifteen (15) days from the receipt of notice from such shareholder that
he agrees to accept such amount upon the surrender of the share certificates
duly endorsed;
<PAGE>
 
     (6)   In case such corporation thus rejects the amount claimed in such
demand as the fair value of such shares and tenders its estimate and offer, such
shareholder shall, within ten (10) days from the receipt of such estimate and
offer, give written notice to such corporation either setting out that he
accepts the valuation estimated by the corporation or stating that he rejects
such estimate and offer. If such shareholder rejects such estimate and offer and
the fair value of such shares be not agreed upon in writing within fifteen (15)
days from the giving or mailing of such notice of rejection, either party may
proceed in a civil action to have such fair value determined;

     (7)   If the fair value be established by agreement between the parties,
such amount agreed upon in writing shall be paid by such corporation within
fifteen (15) days after such agreement, and in case of default in payment
thereof an action may be brought for the full amount agreed upon with interest
from the end of such fifteen-day period in the same manner as an action brought
upon any contract and the period of limitations shall be the same as in the case
of an action upon a written contract; provided, however, that the statutes of
limitations shall be tolled during the time such payment is suspended by the
provisions of Sections 145 and 161g of this act;

     (8)   If such shareholder fails to substantially carry out the procedure
prescribed by this section, he shall, as of the date of such default, be deemed
to have waived his right to dissent to such corporate action, and if such
corporation fail to substantially comply with such procedure, it shall be deemed
to have rejected the offer by the shareholder who may then proceed with a civil
action as herein provided.

     (9)   Any agreement between such corporation and dissenting shareholders
fixing the fair value of shares upon which payment is being demanded shall be
filed with the secretary of the corporation.

(S) 1.160.  Action to fix value of dissenting shares

     a.    Any dissenting shareholder of a domestic corporation or any such
corporation in whose behalf a cause of action to have the fair value of
dissenting shares determined has accrued may, within thirty (30) days after the
accrual thereof but not thereafter, file a petition in the district court of the
county in which the registered office of such corporation is located to have the
fair value of such dissenting shares determined.  If such petition be not filed
within such period, then such shareholder shall be deemed to have waived his
right to dissent.

     e.    Any party shall have the right of appeal from such judgment, and the
costs of such action shall be assessed or apportioned as the court may consider

INFORMATION NOT REQUIRED IN PROSPECTUS


Item 20 -- Indemnification of Directors and Officers

The HSOG Bylaws provide that the registrant shall indemnify its officers and
directors as permitted by the Oklahoma General Corporation Act. Pursuant to
Section 1031 of the Oklahoma General Corporation Act, the registrant generally
has the power to indemnify its present and former directors and officers against
expenses and liabilities incurred by them in connection with any suit to which
they are, or are threatened to be made, a party by reason of their serving in
those positions so long as they acted in good faith and in a manner they
reasonably believed to be in, or not opposed to, the best interests of the
registrant, and with respect to any criminal action, they had no reasonable
cause to believe their conduct was unlawful. With respect to suits by or in the
right of the registrant, however, indemnification is generally limited to
attorneys' fees and other expenses and is not available if the person is
adjudged to be liable to the registrant unless the court determines that
indemnification is appropriate. The statute expressly provides that the power to
indemnify authorized thereby is not exclusive of any rights granted under any
bylaw, agreement, vote of stockholders or disinterested directors, or otherwise.
The registrant also has the power to purchase and maintain insurance for its
directors and officers.

The preceding discussion of the registrant's bylaws and Section 1031 of the
Oklahoma General Corporation Act is not intended to be exhaustive and is
qualified in its entirety by the HSOG Bylaws and Section 1031 of the Oklahoma
General Corporation Act.

Item 22 -- Undertakings

(a) The undersigned registrant hereby undertakes:

    (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

        (i)    To include any prospectus required by Section 10(a)(3) of the
   Securities Act.

        (ii)   To reflect in the prospectus any facts or events arising after
   the effective date of this Registration Statement (or the most recent post-
   effective amendment thereof) which, individually or in the aggregate,
   represent a fundamental change in the information set forth in this
   Registration Statement; and

        (iii)  To include any material information with respect to the plan of
   distribution not previously disclosed in this Registration Statement or any
   material change to such information in this Registration Statement;

provided, however, that clauses (i) and (ii) above do not apply if the
information required to be included in a post-effective amendment by those
clauses is contained in periodic reports filed by the registrant pursuant to
Section 13 or Section 15(d) of the Exchange Act that are incorporated by
reference into this Registration Statement;

    (2) That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof; and

    (3) To remove from registration by means of a post-effective amendment any
of the securities being registered that remain unsold at the termination of the
offering.

(b) Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers, and controlling persons of the
registrant pursuant to the provisions described in Item 20 above or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer, or
controlling person of the registrant in the successful defense of any action,
suit, or proceeding) is asserted by such director, officer, or controlling
person in connection with the securities being registered, the registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

(c) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the Registration Statement through the
date of responding to such request.

(d) The undersigned registrant hereby undertakes to supply by means of a post-
effective amendment all information concerning a transaction, and the company
being acquired involved therein, that was not the subject of and included in the
Registration Statement when it became effective.
