                              AGREEMENT OF MERGER


        This Agreement of Merger, dated as of the 24th day of March, 1994  (the
"Agreement"), is among K N Energy, Inc., a Kansas corporation ("KNE"), KNE
Acquisition Corporation, a newly-formed Delaware corporation and a wholly-owned
subsidiary of KNE ("Sub"), and American Oil and Gas Corporation, a Delaware
corporation ("AOG").

        WHEREAS, subject to and in accordance with the terms and conditions of
this Agreement, the respective Boards of Directors of KNE, Sub and AOG, and KNE
as sole stockholder of Sub, have approved the merger of Sub with and into AOG
(the "Merger"), whereby each issued and outstanding share of common stock, par
value $.04 per share, of AOG ("AOG Common Stock") will be converted into the
right to receive common stock, par value $5.00 per share, of KNE ("KNE Common
Stock"), as provided herein;

        WHEREAS, for federal income tax purposes, it is intended that the Merger
shall qualify as a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended (the "Code");

        WHEREAS, the Merger is intended to be treated as a "pooling of
interests" for accounting purposes; and

        WHEREAS, the parties hereto desire to set forth certain representations,
warranties and covenants made by each to the other as an inducement to the
consummation of the Merger;

        NOW, THEREFORE, in consideration of the premises and of the mutual
representations, warranties and covenants herein contained, the parties hereto
hereby agree as follows:


                                   ARTICLE I

                                   THE MERGER

other time and place and on such other date as KNE and AOG shall agree;
provided, that the closing conditions set forth in Article VI shall have been
satisfied or waived at or prior to such time.  The date on which the Closing
occurs is herein referred to as the "Closing Date".

        1.3  Consummation of the Merger.  As soon as practicable on the Closing
Date, the parties hereto will cause the Merger to be consummated by filing with
the Secretary of State of Delaware a certificate of merger in such form as
required by, and executed in accordance with, the relevant provisions of the
DGCL.  The "Effective Time" of the Merger as that term is used in this Agreement
shall mean the effective time set forth in the certified copy of the certificate
of merger issued by the Secretary of State of Delaware with respect to the
Merger.

        1.4  Effect of the Merger.  The Merger shall have the effect set forth
in Section 1.1 hereof and the applicable provisions of the DGCL.

        1.5  Certificate of Incorporation; Bylaws.

                (a) At the Effective Time, the Amended and Restated Certificate
        of Incorporation of AOG, as in effect immediately prior to the Effective
        Time, shall continue to be the certificate of incorporation of AOG, as
        the Surviving Corporation, until duly amended in accordance with law;
        provided, however, that Article IV of the Amended and Restated
        Certificate of Incorporation of AOG shall be amended in its entirety to
        read as follows:

           "The aggregate number of shares which the Corporation shall have
           authority to issue is one thousand (1,000), of the par value of one
           dollar ($1.00) each, to be designated 'Common Stock'."

; and provided further, that Article IX of the Amended and Restated Certificate
of Incorporation of AOG shall be deleted in its entirety and Articles X and XI
renumbered as Articles IX and X, respectively.

                (b) At the Effective Time, the Bylaws of AOG, as in effect
        immediately prior to the Effective Time, shall become the bylaws of AOG,
        as the Surviving Corporation, until duly amended in accordance with law.

        1.6  Directors and Officers.  The persons named in Exhibit 1.6 shall be
the directors of the Surviving Corporation, each to hold office in accordance
with the certificate of incorporation and bylaws of the Surviving Corporation,
and the officers of AOG immediately prior to the Effective Time shall be the
officers of the Surviving Corporation, in each case until their respective
successors are duly elected or appointed and qualified.  If, prior to the
Effective Time, any such designees shall decline or be unable to serve, KNE or
AOG, as the case may be, shall designate another person to serve in such
person's stead.

        1.7  Conversion of Securities; Exchange; Fractional Shares.  Subject to
the terms and conditions of this Agreement, at the Effective Time, by virtue of
the Merger and without any action on the part of AOG, Sub or their stockholders:

                (a) Each share of AOG Common Stock issued and outstanding
        immediately prior to the Effective Time (the "Shares"), shall be
        converted, subject to the provisions of this Section 1.7, into 0.47 
        fully paid and nonassessable shares of KNE Common Stock; provided,
        however, that no fractional shares of KNE Common Stock shall be issued,
        and, in lieu thereof, a cash payment shall be made pursuant to Section
        1.7(g) hereof.

                (b) Each share of AOG Common Stock held in the treasury of AOG
        and each Share owned by Sub, KNE or any direct or indirect wholly-owned
        subsidiary of KNE or of AOG immediately prior to the Effective Time, if
        any, shall be cancelled and extinguished at the Effective Time without
        any conversion thereof and no payment shall be made with respect
        thereto.

                (c) Each share of common stock, par value $1.00 per share, of
        Sub issued and outstanding immediately prior to the Effective Time shall
        be converted into and exchanged at the Effective Time for one validly
        issued, fully paid and nonassessable share of common stock of the
        Surviving Corporation.

                (d) As of the Effective Time, KNE shall deposit with Chemical
        Bank or such other bank or trust company as may be reasonably acceptable
        to each of KNE and AOG (the "Exchange Agent") for the benefit of holders
        of Shares, for exchange in accordance with this Section 1.7,
        certificates representing the shares of KNE Common Stock issuable
        pursuant to Section 1.7(a) hereof.  As soon as reasonably practicable
        after the Effective Time, the Exchange Agent shall mail to each holder
        of record of a certificate or certificates which immediately prior to
        the Effective Time represented Shares (the "Certificates") that were
        converted into shares of KNE Common Stock pursuant to Section 1.7(a),
        (i) a letter of transmittal (which shall specify that delivery shall be
        effected, and risk of loss and title to the Certificates shall pass,
        only by delivery of the Certificates to the Exchange Agent and shall be
        in such form and have such other provisions as KNE and AOG may
        reasonably specify) and (ii) instructions for use in effecting the
        surrender of the Certificates in exchange for certificates representing
        shares of KNE Common Stock.  Upon surrender of a Certificate for
        cancellation to the Exchange Agent together with such letter of
        transmittal, duly executed, the holder of such Certificate shall be
        entitled to receive in exchange therefor a certificate representing the
        number of whole shares of KNE Common Stock which such holder has the
        right to receive in respect of the Certificate surrendered pursuant to
        the provisions of this Section 1.7 (after taking into account all Shares
        then held by such holder), and the Certificate so surrendered shall
        forthwith be canceled.  Until so surrendered, each Certificate shall be
        deemed from and after the Effective Time, for all corporate purposes,
        other than the payment of earlier dividends and distributions, to
        evidence the ownership of the number of full shares of KNE Common Stock
        into which such Shares shall have been converted pursuant to this
        Section 1.7.  Unless and until any such Certificates shall be
        surrendered, no dividends or other distributions payable to the holders
        of record of KNE Common Stock, as of any time on or after the Effective
        Time, shall be paid to the holders of such Certificates; provided,
        however, that, upon surrender and exchange of such Certificates, subject
        to any applicable escheat laws and paragraph D.3 of Section 4 of Article
        Sixth of the Restated Articles of Incorporation of KNE, there shall be
        paid to the record holders of the certificates issued and exchanged
        therefor the amount, without interest thereon, of dividends and other
        distributions, if any, that theretofore were declared and became payable
        since the Effective Time with respect to the number of full shares of
        KNE Common Stock issued to such holders.

                (e) All shares of KNE Common Stock into which the Shares shall
        have been converted pursuant to this Section 1.7 shall be issued in full
        satisfaction of all rights pertaining to such converted Shares.

                (f) If any certificate for shares of KNE Common Stock is to be
        issued in a name other than that in which the Certificate surrendered in
        exchange therefor is registered, it shall be a condition of the issuance
        thereof that the Certificate so surrendered shall be properly endorsed
        and otherwise in proper form for transfer and that the person requesting
        such exchange shall have paid to KNE or the Exchange  Agent any transfer
        or other taxes required by reason of the issuance of a certificate for
        shares of KNE Common Stock in any name other than that of the registered
        holder of the Certificate surrendered, or established to the
        satisfaction of KNE or the Exchange Agent that such tax has been paid or
        is not payable.

                (g) No fraction of a share of KNE Common Stock shall be issued,
        but in lieu thereof each holder of Shares who would otherwise be
        entitled to a fraction of a share of KNE Common Stock shall, upon
        surrender of the Certificate representing such Shares to the Exchange
        Agent, be paid an amount in cash equal to the value of such fraction of
        a share based upon the closing price of KNE Common Stock on the New York
        Stock Exchange Composite Tape on the last trading day prior to the
        Effective Time.  No interest shall be paid on such amount.  KNE shall
        provide the Exchange Agent with sufficient funds to make all payments
        due under this Section 1.7(g).  All Shares held by a record holder shall
        be aggregated for purposes of computing the number of shares of KNE
        Common Stock to be issued pursuant to this Section 1.7.

                (h) None of KNE, Sub, AOG, or their officers, directors,
        transfer agents or the Exchange Agent shall be liable to a holder of
        Shares for any amount properly paid to a public official pursuant to
        applicable property, escheat or similar laws.

        1.8  No Dissenters' Rights.  The shares of KNE Common Stock and the

                                   ARTICLE II

                         REPRESENTATIONS AND WARRANTIES

        2.1  Representations and Warranties of KNE and Sub.  KNE and Sub hereby
represent and warrant to AOG that:

                (a) Organization and Compliance with Law.  KNE and each
        Significant Subsidiary (as such term is defined below) of KNE is a
        corporation or partnership duly organized, validly existing and in good
        standing under the laws of the jurisdiction in which it is chartered or
        organized and has all requisite corporate or partnership power and
        authority and all necessary governmental authorizations to own, lease
        and operate all of its properties and assets and to carry on its
        business as now being conducted, except where the failure to have any
        such governmental authorization would not have a material adverse effect
        on KNE.  Except as set forth in a disclosure letter delivered by KNE to
        AOG on the date hereof (the "KNE Disclosure Letter"), each of KNE and
        its Subsidiaries is duly qualified as a foreign corporation or
        partnership to do business, and is in good standing, in each
        jurisdiction in which the property owned, leased or operated by it or
        the nature of the business conducted by it makes such qualification
        necessary, except in such jurisdictions where the failure to be duly
        qualified does not and would not, either individually or in the
        aggregate, have a material adverse effect on KNE.  KNE and each of its
        Subsidiaries are in compliance with all applicable laws, judgments,
        orders, rules and regulations, domestic and foreign, except where
        failure to be in such compliance would not have a material adverse
        effect on KNE.  KNE has heretofore delivered to AOG true and complete
        copies of KNE's Restated Articles of Incorporation including the
        designations of rights, powers and preferences of the KNE Preferred (as
        defined below) (the "KNE Articles") and bylaws of KNE, as amended, and
        as in existence on the date hereof.  Exhibit 2.1(a) hereto sets forth
        each of the Significant Subsidiaries of KNE and the respective
        jurisdiction of its incorporation or formation.  As used in this
        Agreement, (i) the word "Subsidiary", when used with respect to any
        party, means any corporation, or any partnership or other business
        entity of which such party (or any other Subsidiary of such party) is a
        general partner (excluding partnerships, the aggregate general partner
        interests of which held by such party (or a Subsidiary of such party) do
        not constitute a majority of the voting interests of such partnership),
        at least a majority of the securities or other interests having by their
        terms ordinary voting power to elect a majority of the board of
        directors or others performing similar functions with respect to such
        corporation, partnership or other business entity is directly or
        indirectly owned or controlled by such party or by any one or more of
        its Subsidiaries, or by such party and one or more of its Subsidiaries;
        (ii) a "Significant Subsidiary" means any Subsidiary of KNE or AOG, as
        the case may be, that would constitute a "significant subsidiary" of
        such party within the meaning of Rule 1-02 of Regulation S-X promulgated
        by the Securities and Exchange Commission (the "Commission"); (iii) any
        reference to any event, change, condition or effect being "material"
        with respect to any entity means an event, change, condition or effect
        which is material in relation to the condition (financial or otherwise),
        assets, liabilities, business or operations of such entity and its
        Subsidiaries taken as a whole; and (iv) the term "material adverse
        effect" means, with respect to KNE and AOG, a material adverse effect of
        the business, assets, results of operations or condition (financial or
        otherwise) of such party and its  Subsidiaries taken as a whole or on
        the ability of such party (and, with respect to KNE, of Sub) to perform
        its obligations hereunder.

           (b) Capitalization.
               (i)  The authorized capital stock of KNE consists of
                    25,000,000  shares of KNE Common Stock, of which 15,035,301
                    were legally issued and outstanding on December 31, 1993;
                    200,000 shares of Class A Preferred Stock, no par value
                    ("Class A Preferred Stock"), of which 5,000 shares were
                    legally issued and outstanding as Class A $8.50 Cumulative
                    Preferred Stock on such  date, and 70,000 shares were
                    legally issued and outstanding as Class A $5.00 Cumulative
                    Preferred Stock on such date; and 2,000,000 shares of Class
                    B Preferred Stock, no par value ("Class B Preferred Stock"),
                    of which 28,576 shares were legally issued and outstanding
                    as Class B $8.30 Series Cumulative Preferred Stock on such
                    date.  (The Class A Preferred Stock and the Class B
                    Preferred Stock are referred to collectively as the "KNE
                    Preferred.") As of December 31, 1993, there were reserved
                    for issuance 2,111,299 shares of KNE Common Stock under
                    KNE's (A) incentive stock option plans for key employees and
                    nonqualified stock option plans for nonemployee directors,
                    (B) Dividend Reinvestment and Cash Investment Plan, (C)
                    Employees Retirement Trust Fund Profit Sharing Plan and (D)
                    other employee benefit plans (collectively, the "KNE Stock
                    Plans"). Subject to shareholder approval of KNE's 1994
                    Long-Term Incentive Plan (the "KNE LTIP") at KNE's 1994
                    annual meeting of shareholders, an additional 700,000 shares
                    of KNE Common Stock will be reserved for issuance
                    thereunder.  All issued shares of KNE Common Stock are
                    validly issued, fully paid and nonassessable and no holder
                    thereof is entitled to preemptive rights.  All shares of KNE
                    Common Stock to be issued pursuant to the Merger, when
                    issued in accordance with this Agreement, will be validly
                    issued, fully paid and nonassessable and will not violate
                    the preemptive rights of any person.  KNE is not a party to,
                    and is not aware of, any voting agreement, voting trust or
                    similar agreement or arrangement relating to any class or
                    series of its capital stock, or, except as contemplated
                    hereby, any agreement or arrangement providing for
                    registration rights with respect to any capital stock or
                    other securities of KNE.  Except as set forth in the KNE
                    Disclosure Letter, all outstanding shares of capital stock
                    of, or partnership interests in, the KNE Significant
                    Subsidiaries are owned by KNE or a direct or indirect
                    wholly-owned subsidiary of KNE, free and clear of all liens,
                    minority interests, charges, encumbrances, adverse claims
                    and options of any nature which are material to KNE. As of
                    the date hereof and immediately prior to the Effective Time,
                    the authorized capital stock of Sub consists of 1,000 shares
                    of common stock, par value $1.00 per share, all of which are
                    validly issued, fully paid and nonassessable and are
                    directly owned by KNE.
              (ii)  As of December 31, 1993, options to purchase 426,678
                    shares of KNE Common Stock were outstanding and
                    options to purchase an additional 171,174 such shares were
                    available for grant pursuant to the plans set forth in
                    Section 2.1(b)(i)(A) above, and subsequent to such date and
                    subject to shareholder approval of the KNE LTIP, options,
                    stock appreciation rights, restricted shares and other types
                    of stock-based awards relating to an aggregate of 700,000
                    shares of KNE Common Stock became available for grant
                    pursuant to the KNE LTIP.  Since December 31, 1993, there
                    have been no options, stock appreciation rights, restricted
                    shares or other types of stock- based awards granted by KNE,
                    except as disclosed in the KNE Disclosure Letter.  Other
                    than as set forth in the first sentence of each of Section
                    2.1(b)(i) and 2.1(b)(ii) and other than as contemplated by
                    this Agreement to be issued in connection with the Merger,
                    there are not now, and at the Effective Time there will not
                    be, any (A) shares of capital stock of KNE outstanding
                    (other than KNE Common Stock issued pursuant to the KNE
                    Stock Plans) or (B) outstanding options, warrants, scrip,

                    rights to subscribe for, calls or commitments of any
                    character whatsoever relating to, or securities or rights
                    convertible into or exchangeable for, shares of any class of
                    capital stock of KNE or any of its corporate Significant
                    Subsidiaries, or contracts, understandings or arrangements
                    to which KNE or any of its Significant Subsidiaries is a
                    party, or by which it is or may be bound, to issue
                    additional shares of its or any Significant Subsidiary's
                    capital stock or equity interest or options, warrants, scrip
                    or rights to subscribe for, or securities or rights
                    convertible into or exchangeable for, any additional shares
                    of its or any Significant Subsidiary's capital stock or
                    equity interest or (C) issued and outstanding bonds,
                    debentures, notes or other indebtedness of KNE or any its
                    Significant Subsidiaries having the right to vote (or
                    convertible into or exercisable for securities having the
                    right to vote) on any matters on which stockholders of KNE
                    or its Significant Subsidiaries, as the case may be, may
                    vote.  All shares of KNE Common Stock issued pursuant to the
                    exercise of outstanding options granted pursuant to the KNE
                    Stock Plans will be validly issued, fully paid and
                    nonassessable and no holder thereof will be entitled to
                    preemptive rights.

                (c) Authorization and Validity of Agreement.  KNE and Sub have
        all requisite corporate power and authority to enter into this Agreement
        and to perform their obligations hereunder.  The execution and delivery
        by KNE and Sub of this Agreement and the consummation by each of them of
        the transactions contemplated hereby have been duly authorized by all
        necessary corporate action.  This Agreement has been duly executed and
        delivered by KNE and Sub and is the valid and binding obligation of KNE
        and Sub, enforceable against KNE and Sub in accordance with its terms.

                (d) No Approvals or Notices Required; No Conflict with
        Instruments to which KNE or any of its Significant Subsidiaries is a
        Party.  Neither the execution and delivery of this Agreement nor the
        performance by KNE or Sub of its obligations hereunder, nor the
        consummation of the transactions contemplated hereby by KNE and Sub,
        will (i) conflict with the KNE Articles or bylaws of KNE or the
        partnership agreement, charter or bylaws of any of its Significant
        Subsidiaries; (ii) assuming satisfaction of the requirements set forth
        in clause (iii) below, violate any provision of law applicable to KNE or
        any of its Subsidiaries; (iii) except for (A) filing with the Commission
        of (x) a joint proxy statement in preliminary form relating to the
        meetings of KNE's and AOG's stockholders to be held for the purpose of
        obtaining stockholder approvals relating to the Merger (the "Proxy
        Statement"), (y) such reports under Section 13(a) of the Securities
        Exchange Act of 1934, as amended (the "Exchange Act") as may be required

        hereby, and (z) the registration statements referred to in Sections 5.1
        and 5.14(c) hereof, (B) requirements arising out of the
        Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act"),

        the Wyoming Public Service Commission (the "PSC"), (D) the filing of a
        certificate of merger by Sub in accordance with the DGCL, and (E) such
        filings, qualifications and approvals as may be required under state
        securities or takeover laws, require any consent or approval of, or
        filing with or notice to, any public body or authority, domestic or
        foreign, under any provision of law applicable to KNE or any of its
        Subsidiaries; or (iv) require any consent, approval or notice under, or
        violate, breach, be in conflict with or constitute a default (or an
        event that, with notice or lapse of time or both, would constitute a
        default) under, or permit the termination of any provision of, or result
        in the creation or imposition of any lien upon any properties, assets or
        business of KNE or any of its Subsidiaries under, any note, bond,
        indenture, mortgage, deed of trust, lease, franchise, permit,
        authorization, license, employee benefit plan, contract, instrument or
        other agreement or commitment or any order, judgment or decree to which
        KNE or any of its Subsidiaries is a party or by which KNE or any of its
        Subsidiaries or any of its assets or properties is bound or encumbered,
        except (A) those that have already been given, obtained or filed and (B)
        those that are set forth in the KNE Disclosure Letter, which will be
        obtained prior to the Effective Time, and except in any of the cases
        enumerated in clauses (ii) through (iv) those that, in the aggregate,
        would not have a material adverse effect on KNE.

                (e) Commission Filings; Financial Statements; Information
        Supplied.  Since January 1, 1991, KNE has filed all reports,
        registration statements and other filings, together with any amendments
        required to be made with respect thereto, that it has been required to
        file with the Commission under the Securities Act of 1933, as amended
        (the "Securities Act"), and the Exchange Act.  All reports, registration
        statements and other filings (including all notes, exhibits and
        schedules thereto and documents incorporated by reference therein but
        excluding any preliminary proxy material) filed by KNE with the
        Commission since January 1, 1991 through the date of this Agreement,
        together with any amendments thereto, are sometimes collectively
        referred to as the "KNE Commission Filings".  As of the respective dates
        of their filing with the Commission, the KNE Commission Filings
        complied, and the Registration Statement (as defined in Section 5.1) and
        the Proxy Statement (except with respect to information concerning AOG
        and its Significant Subsidiaries furnished by or on behalf of AOG to KNE
        specifically for use therein) will comply, at the time of effectiveness
        of the Registration Statement and the initial date of mailing of the
        Proxy Statement to stockholders of each of KNE and AOG, in all material
        respects with the Securities Act, the Exchange Act and the rules and
        regulations of the Commission promulgated thereunder, and did not or
        will not, as the case may be, at such time or date, contain any untrue
        statement of a material fact or omit to state a material fact required
        to be stated therein or necessary to make the statements made therein,
        in light of the circumstances under which they were made, not
        misleading.

                All material contracts of KNE and its Subsidiaries have been
        included in the KNE Commission Filings, except for those contracts not
        required to be filed, pursuant to the rules and regulations of the
        Commission.

                Each of the consolidated financial statements (including any
        related notes or schedules) included in the KNE Commission Filings (i)
        was, and each of the consolidated financial statements to be included in
        the Registration Statement and Proxy Statement (except for those
        financial statements of AOG and its Significant Subsidiaries furnished
        by or on behalf of AOG to KNE specifically for use therein) will be, in
        compliance as to form in all material respects with applicable
        accounting requirements and with the published rules and regulations of
        the Commission with respect thereto, (ii) was or will be, as the case
        may be, prepared in accordance with generally accepted accounting
        principles applied on a consistent basis (except as may be noted therein
        or in the notes or schedules thereto or, in the case of unaudited
        financial statements, as permitted by Form 10-Q and Regulation S-X of
        the Commission), and (iii) fairly presents or will fairly present, as
        the case may be, the consolidated financial position of KNE and its
        consolidated Significant Subsidiaries as of the dates thereof and the
        results of operations and cash flows for the periods then ended
        (subject, in the case of the unaudited interim financial statements, to
        normal year-end audit adjustments on a basis comparable with past
        periods).  As of the date hereof, neither KNE nor its Subsidiaries has
        any liabilities, absolute or contingent, that are material to KNE and
        not reflected in the KNE Commission Filings, except (i) those incurred
        in the ordinary course of business consistent with past operations, and
        (ii) those set forth in the KNE Disclosure Letter.

                (f) Conduct of Business in the Ordinary Course; Absence of
        Certain Changes and Events.  Since January 1, 1993, except as
        contemplated by this Agreement, disclosed in the KNE Commission Filings
        filed with the Commission since that date or set forth in the KNE
        Disclosure Letter, KNE and its Significant Subsidiaries have conducted
        their business only in the ordinary and usual course, and there has not
        been (i) any material adverse effect on such business, or any condition,
        event or development that reasonably may be expected to result in any
        such material adverse effect on such business; (ii) any change by KNE in
        its accounting methods, principles or practices; (iii) any revaluation
        by KNE or any of its Significant Subsidiaries of any of its or their
        assets, including, without limitation, writing down the value of
        inventory or writing off notes or accounts receivable other than in the
        ordinary course of business; (iv) any entry by KNE or any of its
        Significant Subsidiaries into any commitment or transaction material to
        KNE; (v) any declaration, setting aside or payment of any dividends or
        distributions in respect of the KNE Common Stock or KNE Preferred,
        except for the regular periodic cash dividends on the KNE Common Stock
        and the KNE Preferred, or any redemption, purchase or other acquisition
        of any of its securities or any securities of any of its Significant
        Subsidiaries (other than acquisitions of KNE Common Stock pursuant to
        previously authorized approval of the KNE Board of Directors or KNE
        Preferred to satisfy sinking fund obligations); (vi) any damage,
        destruction or loss (whether or not covered by insurance) having a
        material





                                      -7-
<PAGE>   12
        adverse effect on KNE; (vii) any increase in long-term
        indebtedness for borrowed money; (viii) any granting of a security
        interest or lien on any material property or assets of KNE and its
        Significant Subsidiaries, taken as a whole, other than (A) liens for
        taxes not due and payable or which are being contested in good faith;
        (B) mechanics', warehousemen's and other statutory liens incurred in the
        ordinary course of business; and (C) defects and irregularities in title
        and encumbrances which are not substantial in character or amount and do
        not materially impair the use of the property or asset in question
        (collectively, "Permitted Liens"); or (ix) except in the ordinary course
        of business and consistent with past practice, any increase in or
        establishment of any bonus, insurance, severance, deferred compensation,
        pension, retirement, profit sharing, stock option (including, without
        limitation, the granting of stock options, stock appreciation rights,
        performance awards or restricted stock awards), stock purchase or other
        employee benefit plan or any other increase in the compensation payable
        or to become payable to any officers or key employees of KNE or any of
        its Significant Subsidiaries, except for the establishment of the KNE
        LTIP and, subject to shareholder approval of such plan, grants of awards
        thereunder.

                (g) Certain Fees.  With the exception of the engagement of
        Petrie Parkman & Co., Inc. and Rauscher Pierce Refsnes, Inc., neither
        KNE nor any of its officers, directors or employees, on behalf of KNE or
        any of its Subsidiaries or its or their respective Boards of Directors
        (or any committee thereof), has employed any financial advisor, broker
        or finder or incurred any liability for any financial advisory,
        brokerage or finders' fees or commissions in connection with the
        transaction contemplated hereby.

                (h) Litigation.  Except as disclosed in the KNE Commission
        Filings or set forth in the KNE Disclosure Letter, there are no claims,
        actions, suits, investigations or proceedings pending or, to the
        knowledge of KNE, threatened against or affecting KNE or any of the KNE
        Significant Subsidiaries or any of their respective properties at law or
        in equity, or any of their respective employee benefit plans or
        fiduciaries of such plans, or before or by any federal, state, municipal
        or other governmental agency or authority, or before any arbitration
        board or panel, wherever located, that individually or in the aggregate
        if adversely determined would have a material adverse effect on KNE, or
        that involve a material risk of criminal liability.

                (i) Employee Benefit Plans.  There are no "employee pension
        benefit plans," as such term is defined in Section 3(2) of the Employee
        Retirement Income Security Act of 1974, as amended ("ERISA"), maintained
        by KNE or its Significant Subsidiaries for the benefit of their
        employees except for those plans (each a "KNE Pension Plan") disclosed
        in KNE's Proxy Statement dated February 26, 1993 or in the KNE
        Disclosure Letter.  Each "employee benefit plan," as such term is
        defined in Section 3(3) of ERISA, including such plans that may not be
        subject to ERISA such as foreign plans maintained by KNE or a Subsidiary
        (each a "KNE Benefit Plan") complies in all material respects with all
        applicable requirements of ERISA, the Code and other applicable laws.
        Neither KNE nor any Subsidiary, nor any of their respective directors,
        officers, employees or agents, has, with respect to any KNE Benefit
        Plan, engaged in any conduct that would result in any taxes or penalties
        on prohibited transactions under Section 4975 of the Code or under
        Section 502(i) of ERISA or in any breach of fiduciary duty liability
        under Section 409 of ERISA, which in the aggregate could be material to
        KNE.

        Each of KNE and its Subsidiaries has fulfilled its obligations
        to the extent applicable under the minimum funding requirements of
        Section 302 of ERISA and Section 412 of the Code with respect to each
        KNE Pension Plan.  The assets of each KNE Pension Plan that is subject
        to Title IV of ERISA exceed the present value of vested benefits accrued
        under such plan, determined as of December 31, 1992 on a termination
        basis using the actuarial assumptions established by the Pension Benefit
        Guaranty Corporation (the "PBGC") as in effect on such date.  Neither
        KNE nor any Subsidiary has, or expects to have, any obligation or
        liability (whether accrued, contingent, secondary or otherwise) to
        contribute to any "multiemployer plan," as defined in Section 3(37) of
        ERISA, and neither KNE nor any Subsidiary has any material liability
        under (i) Title IV of ERISA (excluding liability for required premium
        payments) to the PBGC in connection with any KNE Pension Plan that is
        subject to Title IV of ERISA or (ii) Subtitle J, Coal Industry Health
        Benefits, of the Code.

<PAGE>   13
        The Internal Revenue Service (the "IRS") has issued for
        each KNE Pension Plan intended to be qualified under Section 401(a) of
        the Code a letter determining that such plan is exempt from United
        States federal income tax under Sections 401(a) and 501 (a) of the Code
        and approving the form of such plan as amended to comply with the
        requirements of the Tax Equity and Fiscal Responsibility Act of 1982, as
        amended ("TEFRA"), the Tax Reform Act of 1984, as amended ("TRA"), and
        the Retirement Equity Act of 1984, as amended ("REA"), and there has
        been no occurrence since the date of any such determination letter which
        has adversely affected such qualification.

                Except as disclosed in the notes to the latest audited financial
        statements included in the KNE Commission Filings or as set forth in the
        KNE Disclosure Letter, neither KNE nor any Subsidiary has any obligation
        to provide welfare benefits to any of its former employees except to the
        extent required by COBRA.

                Upon request, KNE will furnish AOG true and complete copies as
        in effect on the date hereof of each of (A) the KNE Benefit Plans,
        including without limitation the KNE Pension Plans, the KNE Stock Plans
        and the KNE LTIP, (B) the most recent summary plan description for each
        KNE Benefit Plan for which a summary plan description is required, (C)
        each trust agreement and group annuity contract, if any relating to the
        KNE Benefit Plans, (D) the most recent reports on Form 5500 filed with
        the IRS with respect to any KNE Benefit Plan, (E) the most recent
        actuarial report or valuation relating to a KNE Benefit Plan subject to
        Title IV of ERISA and (F) the most recent determination letter issued by
        the IRS with respect to any KNE Benefit Plan qualified under Section
        401(a) of the Code.

                (j) Taxes.  Except as set forth in the KNE Disclosure Letter,
        all returns and reports, including, without limitation, information and
        withholding returns and reports ("Tax Returns"), of or relating to any
        foreign, federal, state or local tax, assessment or other governmental
        charge ("Taxes" or a "Tax") that are required to be filed on or before
        the Closing Date by or with respect to KNE or any of its Subsidiaries or
        any other corporation that is or was a member of an affiliated group
        (within the meaning of Section 1504(a) of the Code) of corporations of
        which KNE was a member for any period ending on or before the Closing
        Date and with respect to which such corporation was a member of such
        affiliated group, have been or will be duly and timely filed, and all
        Taxes, including interest and penalties, due and payable pursuant to
        such Tax Returns have been paid or, except as set forth in the KNE
        Disclosure Letter, adequately provided for in reserves established by
        KNE, except where the failure to file, pay or provide for would not have
        a material adverse effect on KNE.  Except as set forth in the KNE
        Disclosure Letter, (i) all Tax Returns of or with respect to KNE and its
        Significant Subsidiaries have been audited by the applicable
        governmental authority, or the applicable statute of limitations has
        expired, for all periods up to and including the taxable year ended
        December 31, 1985 and (ii) there are no outstanding audits, examinations
        or other proceedings with respect to any periods covered by Tax Returns
        which involve or could involve the payment of any material Taxes.  There
        is no material claim against KNE or any of its Subsidiaries with respect
        to any Taxes, and no material assessment, deficiency or adjustment has
        been asserted or proposed with respect to any Tax Return of or with
        respect to KNE or any of its Subsidiaries that has not been adequately
        provided for in reserves established by KNE.  The total amounts set up
        as liabilities for current and deferred Taxes in the consolidated
        financial statements included in the KNE Commission Filings have been
        established in accordance with generally accepted accounting principles
        and, except as set forth in the KNE Disclosure Letter, are sufficient to
        cover the payment of all material Taxes in the aggregate, including any
        penalties or interest thereon and whether or not assessed or disputed,
        that are, or are hereafter found to be, or to have been, due with
        respect to the operations of KNE and its Significant Subsidiaries
        through the periods covered thereby.

                KNE has no plan or intention to (i) liquidate the Surviving
        Corporation, (ii) merge the Surviving Corporation with or into another
        corporation, (iii) sell or otherwise dispose of stock of the Surviving
        Corporation (or cause the Surviving Corporation to issue additional
        shares of its capital stock) that would result in KNE losing control of
        the Surviving Corporation within the meaning of Section 368(c) of the
        Code), (iv) cause or permit the Surviving Corporation to sell or
        otherwise dispose of any of the assets





                                      -9-

        acquired from AOG or the assets acquired from Sub except for
        dispositions made in the ordinary course of business or transfers of
        assets to a corporation controlled (within the meaning of Section 368(c)
        of the Code) by the Surviving Corporation, (v) reacquire any of the
        stock issued to the AOG stockholders pursuant to the Merger, or (vi)
        cause or permit the Surviving Corporation to discontinue the historic
        business of AOG.

                KNE does not own, nor has it owned during the past five years,
        any shares of the capital stock of AOG.

                KNE is not an investment company as defined in Section
        368(a)(2)(F)(iii) and (iv) of the Code.

                (k) Environmental.  Except as set forth in the KNE Disclosure
        Letter, KNE and its Subsidiaries are in substantial compliance with all
        applicable federal, state and local laws and regulations relating to
        pollution control and environmental contamination including, but not
        limited to, all laws and regulations governing the generation, use,
        collection, treatment, storage, transportation, recovery, removal,
        discharge or disposal of Hazardous Materials and all laws and
        regulations with regard to recordkeeping, notification and reporting
        requirements respecting Hazardous Materials.  For purposes of this
        Section 2.1(k), "substantial compliance" shall mean compliance, except
        to the extent that failure to comply would not have a material adverse
        effect on KNE.

                Except as set forth in the KNE Disclosure Letter, neither KNE
        nor any of its Subsidiaries is subject to any order or decree of or has
        received, within the past five years, any notice from any governmental
        agency with respect to any alleged violation by KNE or any of its
        Subsidiaries or, to KNE's knowledge, any former Subsidiary, of, or the
        incurrence of any remedial obligation by KNE or its Subsidiaries or, to
        KNE's knowledge, any former Subsidiary, under, any applicable federal,
        state or local environmental or health and safety statutes and
        regulations, which in any instance is material to KNE.

                The term "Hazardous Materials" shall mean material, substances,
        waste or by-products defined as "hazardous substances", "hazardous
        wastes" or "solid wastes" in the Comprehensive Environmental Response,
        Compensation, and Liability Act of 1980, 42 U.S.C. Sections 9601-9657
        and any amendments thereto ("CERCLA"), the Resource Conservation and
        Recovery Act, 42 U.S.C. Sections 6901-6987 and any amendments thereto
        ("RCRA"), or any other applicable federal, state or local environmental
        statute or regulation defining such terms.

                (l) Certain Agreements.  Except as disclosed in the KNE
        Commission Filings filed prior to the date of this Agreement or as
        disclosed in the KNE Disclosure Letter or as provided under this
        Agreement, neither KNE nor any of its Significant Subsidiaries is a
        party to any oral or written (i) agreement with, or obligation to, any
        executive officer or key employee of KNE or any of its Significant
        Subsidiaries (A) for any term of employment or guaranteed compensation
        of such person by KNE or any of its Significant Subsidiaries beyond a
        period of three months or (B) the benefits of which are contingent, or
        the terms of which are materially altered, upon the occurrence of a
        transaction involving KNE of the nature contemplated in this Agreement,
        or (ii) agreement or plan, including any of the KNE Stock Plans or the
        KNE LTIP, any of the benefits of which will be increased, or the vesting
        of benefits which will be accelerated, by the occurrence of the
        transactions contemplated in this Agreement or the value of which
        benefits will be calculated on the basis of the transactions
        contemplated by this Agreement.

                (m) Voting Requirements.  Approval of the issuance of the KNE
        Common Stock issuable in the Merger by a majority of the votes cast
        thereon by holders of KNE Common Stock and KNE Preferred, voting as a
        single class, at the special stockholders' meeting, is the only vote of
        the holders of any class or series of the capital stock of KNE necessary
        to approve the transactions contemplated by this Agreement.

                (n) Insurance.  The KNE Disclosure Letter sets forth all
        material policies of insurance currently in effect relating to the
        business or operations of KNE and its Significant Subsidiaries.

<PAGE>   15
                (o) Title to Property.  Except as set forth in the KNE
        Disclosure Letter or in the KNE Commission Filings, KNE and each of its
        Significant Subsidiaries have good and indefeasible title to all of
        their material real properties purported to be owned in fee and good
        title to all their other material assets, free and clear of all
        mortgages, liens, charges and encumbrances other than Permitted Liens.

                (p) Interim Operations of Sub.  Sub was formed solely for the
        purpose of engaging in the transactions contemplated hereby, has engaged
        in no other business activities, has no liabilities or obligations
        (except those incurred hereunder) and has conducted its operations only
        as contemplated hereby and will not transfer to AOG any assets subject
        to liabilities in the Merger.

                (q) Utility Status.  Neither KNE nor any of its Subsidiaries is
        a "holding company," a "subsidiary company" of a "holding company," an
        "affiliate" of a "holding company" or a "public utility," within the
        meaning of the Public Utility Holding Company Act of 1935, as amended
        ("PUHCA"), except that KNE is a "gas utility company" within the meaning
        of PUHCA.

                (r) Ownership of AOG Common Stock.  Neither KNE nor any of its
        Subsidiaries, nor to the knowledge of KNE, any of their respective
        affiliates or associates (as such terms are defined under the Exchange
        Act), (i) beneficially owns, directly or indirectly, or (ii) are parties
        to any agreement, arrangement or understanding (other than this
        Agreement) for the purpose of acquiring, holding, voting or disposing
        of, in each case, shares of capital stock of AOG, which in the aggregate
        represent 10% or more of the outstanding shares of capital stock of AOG
        entitled to vote generally in the election of directors.

                (s) Labor Agreements.  Neither the business nor the employment
        activities of AOG and its Subsidiaries, as conducted as of the date of
        this Agreement, nor any of the AOG Employees (as defined in Section
        5.10(f) hereof), will become subject at the Effective Time of the Merger
        to any collective bargaining or other labor agreement to which KNE or
        any of its Subsidiaries is a party, either by operation of law or as a
        consequence of the provisions of any such agreement.

        2.2  Representations and Warranties of AOG.  AOG hereby represents and
warrants to KNE that:

                (a) Organization and Compliance with Law.  AOG and each of its
        Significant Subsidiaries is a corporation or partnership duly organized,
        validly existing and in good standing under the laws of the jurisdiction
        in which it is chartered or organized and has all requisite corporate or
        partnership power and authority and all necessary governmental
        authorizations to own, lease and operate all of its properties and
        assets and to carry on its business as now being conducted, except where
        the failure to have any such governmental authorization would not have a
        material adverse effect on AOG.  AOG and each of its Subsidiaries are
        duly qualified as a foreign corporation or partnership to do business,
        and is in good standing, in each jurisdiction in which the property
        owned, leased or operated by it or the nature of the business conducted
        by it makes such qualification necessary, except in such jurisdictions
        where the failure to be duly qualified does not and would not, either
        individually or in the aggregate, have a material adverse effect AUG.
        AOG and each of its Subsidiaries are in compliance with all applicable
        laws, judgments, orders, rules and regulations, domestic and foreign,
        except where failure to be in such compliance would not have a material
        adverse effect on AOG.  AOG has heretofore delivered to KNE true and
        complete copies of AOG's Amended and Restated Certificate of
        Incorporation (the "AOG Certificate") and bylaws as in existence on the
        date hereof.  Exhibit 2.2(a) hereto sets forth each of the Significant
        Subsidiaries of AOG and the respective jurisdiction of its incorporation
        or formation.

                (b) Capitalization.

                                (i)  The authorized capital stock of AOG
                consists of  50,000,000 shares of AOG Common Stock, par value
                $.04 per share, and 2,000,000 shares of Preferred Stock, $10.00
                par value per share (the "AOG Preferred Stock").  As of the date
                hereof, there were issued and outstanding 25,894,395 shares of
                AOG Common Stock and no shares of AOG Preferred Stock.






                                      -11-
<PAGE>   16
                A total of 1,500,000 shares of AOG Common Stock have
                been reserved for issuance pursuant to the Stock Incentive Plan
                of AOG.  All issued shares of AOG Common Stock are validly
                issued, fully paid and nonassessable and no holder thereof is
                entitled to preemptive rights.  Except for (A) the Standstill
                and Registration Rights Agreement, dated as of November 13, 1989
                (the "Standstill Agreement"), between AOG and Cabot Corporation
                and (B) as set forth in a disclosure letter delivered by AOG to
                KNE on the date hereof (the "AOG Disclosure Letter"), AOG is not
                a party to, and is not aware of, any voting agreement, voting
                trust or similar agreement or arrangement relating to any class
                or series of its capital stock, or any agreement or arrangement
                providing for registration rights with respect to any capital
                stock or other securities of AOG.  Except as set forth in the
                AOG Disclosure Letter, all outstanding shares of capital stock
                of, or partnership interests in, the AOG Significant
                Subsidiaries are owned by AOG or one or more direct or indirect
                wholly-owned subsidiaries of AOG, free and clear of all minority
                interests, liens, charges, encumbrances, adverse claims and
                options of any nature which are material to AOG.

                        (ii)  As of the date hereof, there are (A) outstanding
                options (the "AOG Options") to purchase an aggregate of
                1,185,000 shares of AOG Common Stock under the Stock Incentive
                Plan of AOG and (B) warrants (the "AOG Warrants") to purchase an
                aggregate of 2,557,052 shares of AOG Common Stock.  AOG Warrants
                to purchase 30,600 such shares are exercisable at $3.53 per
                warrant and expire on March 9, 1997, and AOG Warrants to
                purchase 2,526,452 such shares are exercisable at $8.25 per
                warrant and expire on September 30, 1999.  Since December 31,
                1993, there have been no options, stock appreciation rights,
                restricted shares or other types of stock-based awards granted
                by AOG, except as disclosed in the AOG Disclosure Letter.  Other
                than as set forth in this Section 2.2(b), there are not now, and
                at the Effective Time there will not be, any (A) shares of
                capital stock or other equity securities of AOG outstanding
                (other than AOG Common Stock issued pursuant to the exercise of
                AOG Options or AOG Warrants) or (B) outstanding options,
                warrants, scrip, rights to subscribe for, calls or commitments
                of any character whatsoever relating to, or securities or rights
                convertible into or exchangeable for, shares of any class of
                capital stock of AOG or any of its corporate Significant
                Subsidiaries, or contracts, understandings or arrangements to
                which AOG or any of its Significant Subsidiaries is a party, or
                by which it is or may be bound, to issue additional shares of
                its or any Significant Subsidiary's capital stock or options,
                warrants, scrip or rights to subscribe for, or securities or
                rights convertible into or exchangeable for, any additional
                shares of its or any Significant Subsidiary's capital stock or
                (C) issued and outstanding bonds, debentures, notes or other
                indebtedness of AOG or any of its Significant Subsidiaries
                having the right to vote (or convertible into or exercisable for
                securities having the right to vote) on any matters on which
                stockholders of AOG or its Significant Subsidiaries, as the case
                may be, may vote.  All shares of AOG Common Stock issued
                pursuant to the exercise of outstanding options granted pursuant
                to the Stock Incentive Plan of AOG or the AOG Warrants will be
                validly issued, fully paid and nonassessable and no holder
                thereof will be entitled to preemptive rights.

                (c) Authorization and Validity of Agreement.  AOG has all
        requisite corporate power and authority to enter into this Agreement and
        to perform its obligations hereunder.  The execution and delivery by AOG
        of this Agreement and the consummation by it of the transactions
        contemplated hereby have been duly authorized by all necessary corporate
        action (subject only, with respect to the Merger, to adoption of this
        Agreement by its stockholders as provided for in Section 5.3(a)).  On or
        prior to the date hereof the Board of Directors of AOG has determined to
        recommend approval of the Merger to the stockholders of AOG, and such
        determination is in effect as of the date hereof.  This Agreement has
        been duly executed and delivered by AOG and is the valid and binding
        obligation of AOG, enforceable against AOG in accordance with its terms.

                (d) No Approvals or Notices Required; No Conflict with
        Instruments to which AOG or any of its Significant Subsidiaries is a
        Party.  Neither the execution and delivery of this Agreement nor the
        performance by AOG of its obligations hereunder, nor the consummation of
        the transactions contemplated hereby by AOG, will (i) conflict with the
        AOG Certificate or bylaws of AOG or the partnership agreement, charter
        or bylaws of any of its Significant Subsidiaries; (ii) assuming
        satisfaction of the requirements set forth in clause (iii) below,
        violate any provision of law applicable to AOG or any of its
        Subsidiaries; (iii) except for (A) filing with the Commission of (x) the
        Proxy Statement in preliminary form and (y) such reports under Section
        13(a) of the Exchange Act as may be required in connection with this
        Agreement and the transactions contemplated hereby, (B) requirements
        arising out of the HSR Act, (C) requirements of notice filings in such
        foreign jurisdictions as may be applicable, (D) the filing of a
        certificate of merger in accordance with the DGCL, and (E) such filings,
        qualifications and approvals as may be required under state securities
        or takeover laws, require any consent or approval of, or filing with or
        notice to, any public body or authority, domestic or foreign, under any
        provision of law applicable to AOG or any of its Subsidiaries; or (iv)
        require any consent, approval or notice under, or violate, breach, be in
        conflict with or constitute a default (or an event that, with notice or
        lapse of time or both, would constitute a default) under, or permit the
        termination of any provision of, or result in the creation or imposition
        of any lien upon any properties, assets or business of AOG or any of its
        Subsidiaries under, any note, bond, indenture, mortgage, deed of trust,
        lease, franchise, permit, authorization, license, employee benefit plan,
        contract, instrument or other agreement or commitment or any order,
        judgment or decree to which AOG or any of its Subsidiaries is a party or
        by which AOG or any of its Subsidiaries or any of its assets or
        properties is bound or encumbered, except (A) those that have already
        been given, obtained or filed and (B) those that are required pursuant
        to loan agreements or leasing arrangements, as set forth in the AOG
        Disclosure Letter, which will be obtained prior to the Effective Time,
        and except in any of the cases enumerated in clauses (ii) through (iv)
        those that, in the aggregate, would not have a material adverse effect
        on AOG.

                (e) Commission Filings; Financial Statements; Information
        Supplied.  Since January 1, 1991, AOG has filed all reports,
        registration statements and other filings, together with any amendments
        required to be made with respect thereto, that they have been required
        to file with the Commission under the Securities Act and the Exchange
        Act.  All reports, registration statements and other filings (including
        all notes, exhibits and schedules thereto and documents incorporated by
        reference therein but excluding any preliminary proxy material) filed by
        AOG with the Commission since January 1, 1991 through the date of this
        Agreement, together with any amendments thereto, are sometimes
        collectively referred to as the "AOG Commission Filings".  AOG has
        heretofore delivered to KNE copies of the AOG Commission Filings.  As of
        the respective dates of their filing with the Commission, the AOG
        Commission Filings complied, and the Proxy Statement (except with
        respect to information concerning KNE and its Significant Subsidiaries
        furnished by or on behalf of KNE to AOG specifically for use therein)
        will comply, at each of the time of effectiveness of the Registration
        Statement and the initial date of mailing of the Proxy Statement to
        stockholders of each of KNE and AOG, in all material respects with the
        Securities Act, the Exchange Act and the rules and regulations of the
        Commission promulgated thereunder, and did not or will not, as the case
        may be, at such time or date, contain any untrue statement of a material
        fact or omit to state a material fact required to be stated therein or
        necessary to make the statements made therein, in light of the
        circumstances under which they were made, not misleading.

                All material contracts of AOG and its Subsidiaries have been
        included in the AOG Commission Filings, except for those contracts not
        required to be filed, pursuant to the rules and regulations of the
        Commission.

                Each of the consolidated financial statements (including any
        related notes or schedules) included in the AOG Commission Filings (i)
        was, and each of the consolidated financial statements to be included in
        the Proxy Statement (except for those financial statements of KNE and
        its Significant Subsidiaries furnished by or on behalf of KNE to AOG
        specifically for use therein) will be, in compliance as to form in all
        material respects with applicable accounting requirements and with the
        published rules and regulations of the Commission with respect thereto,
        (ii) was or will be, as the case may be, prepared in accordance with
        generally accepted accounting principles applied on a consistent basis
        (except as may be





                                      -13-
<PAGE>   18
        noted therein or in the notes or schedules thereto), and (iii)
        fairly presents or will fairly present, as the case may be, the
        consolidated financial position of AOG and its consolidated Significant
        Subsidiaries as of the dates thereof and the results of operations and
        cash flows for the periods then ended (subject, in the case of the
        unaudited interim financial statements, to normal year-end audit
        adjustments on a basis comparable with past periods). As of the date
        hereof, neither AOG nor its Subsidiaries has any liabilities, absolute
        or contingent, that are material to AOG and not reflected in the AOG
        Commission Filings, except (i) those incurred in the ordinary course of
        business consistent with past operations and not relating to the
        borrowing of money, and (ii) those set forth in the AOG Disclosure
        Letter.

                (f) Conduct of Business in the Ordinary Course; Absence of
        Certain Changes and Events.  Since January 1, 1993, except as
        contemplated by this Agreement, disclosed in the AOG Commission Filings
        filed with the Commission since that date or set forth in the AOG
        Disclosure Letter, AOG and its Significant Subsidiaries have conducted
        their business only in the ordinary and usual course, and there has not
        been (i) any material adverse effect on such business, or any condition,
        event or development that reasonably may be expected to result in any
        such material adverse effect on such business; (ii) any change by AOG in
        its accounting methods, principles or practices; (iii) any revaluation
        by AOG or any of its Significant Subsidiaries of any of its or their
        assets, including, without limitation, writing down the value of
        inventory or writing off notes or accounts receivable other than in the
        ordinary course of business; (iv) any entry by AOG or any of its
        Significant Subsidiaries into any commitment or transaction material to
        AOG; (v) any declaration, setting aside or payment of any dividends or
        distributions in respect of the AOG Common Stock or any redemption,
        purchase or other acquisition of any of its securities or any securities
        of any of its Significant Subsidiaries; (vi) any damage, destruction or
        loss (whether or not covered by insurance) having a material adverse
        effect on AOG; (vii) any increase in long-term indebtedness for borrowed
        money; (viii) any granting of a security interest or lien on any
        material property or assets of AOG and its Significant Subsidiaries,
        taken as a whole, other than Permitted Liens; or (ix) except in the
        ordinary course of business and consistent with past practice, any
        increase in or establishment of any bonus, insurance, severance,
        deferred compensation, pension, retirement, profit sharing, stock option
        (including, without limitation, the granting of stock options, stock
        appreciation rights, performance awards or restricted stock awards),
        stock purchase or other employee benefit plan or any other increase in
        the compensation payable or to become payable to any officers or key
        employees of AOG or any of its Significant Subsidiaries.

                (g) Certain Fees.  With the exception of the engagement of
        Goldman, Sachs & Co. ("Goldman Sachs") by AOG, neither AOG nor any of
        its officers, directors or employees, on behalf of AOG or any of its
        Subsidiaries or its or their respective Boards of Directors (or any
        committee thereof), has employed any financial advisor, broker or finder
        or incurred any liability for any financial advisory, brokerage or
        finders' fees or commissions in connection with the transactions
        contemplated hereby.

                (h) Litigation.  Except as disclosed in the AOG Commission
        Filings or set forth in the AOG Disclosure Letter, there are no claims,
        actions, suits, investigations or proceedings pending or, to the
        knowledge of AOG, threatened against or affecting AOG or any of the AOG
        Significant Subsidiaries or any of their respective properties at law or
        in equity, or any of their respective employee benefit plans or
        fiduciaries of such plans, or before or by any federal, state, municipal
        or other governmental agency or authority, or before any arbitration
        board or panel, wherever located, that individually or in the aggregate
        if adversely determined would have a material adverse effect on AOG, or
        that involve a material risk of criminal liability.

                (i) Employee Benefit Plans.  There are no "employee pension
        benefit plans," as such term is defined in Section 3(2) of ERISA,
        maintained by AOG or the AOG Significant Subsidiaries for the benefit of
        their employees, except for those plans (each an "AOG Pension Plan")
        disclosed in the AOG Disclosure Letter. Each "employee benefit plan," as
        such term is defined in Section 3(3) of ERISA, including such plans
        which may not be subject to ERISA such as foreign plans, maintained by
        AOG or any Subsidiary (each an "AOG Benefit Plan") complies in all
        material respects with all applicable requirements of ERISA,





                                      -14-
<PAGE>   19
        the Code and other applicable laws.  Neither AOG nor any AOG
        Subsidiary, nor any of their respective directors, officers, employees
        or agents, has, with respect to any AOG Benefit Plan, engaged in any
        conduct that would result in any taxes or penalties on prohibited
        transactions under Section 4975 of the Code or under Section 502(i) of
        ERISA or in breach of fiduciary duty liability under Section 409 of
        ERISA, which in the aggregate could be material to AOG.

                Neither AOG nor any AOG Subsidiary has, or within the preceding
        five years has had, any obligation to contribute to any "multiemployer
        plan," as defined in Section 3(37) of ERISA, or any plan subject to
        Title IV of ERISA.

                Except for AOG's 401(K) Plan, the IRS has issued for each AOG
        Pension Plan intended to be qualified under Section 401(a) of the Code a
        letter determining that such plan is exempt from United States federal
        income tax under Sections 401(a) and 501(a) of the Code and approving
        the form of such plan as amended to comply with the requirements of
        TEFRA, TRA, and REA, and there has been no occurrence since the date of
        any such determination letter which has adversely affected such
        qualification.

                Except as set forth in the AOG Disclosure Letter, neither AOG
        nor any Subsidiary has any obligation to provide welfare benefits to any
        of its former employees except to the extent required by COBRA.

                Upon request, AOG will furnish KNE true and complete copies as
        in effect on the date hereof of each of (A) the AOG Benefit Plans, (B)
        the most recent summary plan description for each AOG Benefit Plan for
        which a summary plan description is required, (C) each trust agreement
        and group annuity contract, if any relating to the AOG Benefit Plans,
        (D) the most recent reports on Form 5500 filed with the IRS with respect
        to any AOG Benefit Plan, and (E) the most recent determination letter,
        if any, issued by the IRS with respect to any AOG Benefit Plan qualified
        under Section 401(a) of the Code.

                (j) Taxes.  Except as set forth in the AOG Disclosure Letter,
        all Tax Returns of or relating to any Tax that are required to be filed
        on or before the Closing Date by or with respect to AOG or any of its
        Subsidiaries, or any other corporation that is or was a member of an
        affiliated group (within the meaning of Section 1504 (a) of the Code) of
        corporations of which AOG was a member for any period ending on or prior
        to the Closing Date and with respect to which such corporation was a
        member of such affiliated group, have been or will be duly and timely
        filed, and all Taxes, including interest and penalties, due and payable
        pursuant to such Tax Returns have been paid or adequately provided for
        in reserves established by AOG, except where the failure to file, pay or
        provide for would not have a material adverse effect on AOG.  Except as
        set forth in the AOG Disclosure Letter, (i) all Tax Returns of or with
        respect to AOG or any of its Significant Subsidiaries have been audited
        by the applicable governmental authority, or the applicable statute of
        limitations has expired, for all periods up to and including the tax
        year ended December 31, 1985 and (ii) there are no outstanding audits,
        examinations or other proceedings with respect to any period covered by
        Tax Returns which involve or could involve any material Taxes.  There is
        no material claim against AOG or any of its Subsidiaries with respect to
        any Taxes, and no material assessment, deficiency or adjustment has been
        asserted or proposed with respect to any Tax Return of or with respect
        to AOG or any of its Subsidiaries that has not been adequately provided
        for in reserves established by AOG.  The total amounts set up as
        liabilities for current and deferred Taxes in the consolidated financial
        statements included in the AOG Commission Filings have been prepared in
        accordance with generally accepted accounting principles and are
        sufficient to cover the payment of all material Taxes in the aggregate,
        including any penalties or interest thereon and whether or not assessed
        or disputed, that are, or are hereafter found to be, or to have been,
        due with respect to the operations of AOG and its Significant
        Subsidiaries through the periods covered thereby.

                There is no plan or intention by any stockholder of AOG who owns
        five percent or more of the AOG Common Stock, and to the best knowledge
        of the management of AOG there is no plan or intention on the part of
        any of the remaining stockholders of AOG Common Stock, to sell, exchange
        or otherwise dispose of a number of shares of KNE Common Stock to be
        received in the Merger that would reduce





                                      -15-
<PAGE>   20
        the AOG stockholders' ownership of KNE Common Stock to a number
        of shares having a value, as of the Effective Time, of less than 50
        percent of the value of all of the AOG Common Stock (including shares of
        AOG Common Stock exchanged for cash in lieu of fractional shares of KNE
        Common Stock) outstanding immediately prior to the Effective Time.

                AOG and the stockholders of AOG Common Stock will each pay their
        respective expenses, if any, incurred in connection with the Merger.

                There is no intercorporate indebtedness existing between AOG and
        KNE or AOG and Sub that was issued, acquired, or will be settled at a
        discount.

                AOG is not an investment company as defined in Section
        368(a)(2)(F)(iii) and (iv) of the Code.

                AOG is not under the jurisdiction of a court in a Title 11 or
        similar case within the meaning of Section 368(a)(3)(A) of the Code.

                To the knowledge of AOG, the total amount of cash to be received
        by stockholders of AOG Common Stock in lieu of fractional shares of KNE
        Common Stock will not exceed one percent of the total fair market value
        of the KNE Common Stock (as of the Effective Time) to be issued in the
        Merger.

                (k) Environmental.  Except as set forth in the AOG Disclosure
        Letter, AOG and its Subsidiaries are in substantial compliance with all
        applicable federal, state and local laws and regulations relating to
        pollution control and environmental contamination including, but not
        limited to, all laws and regulations governing the generation, use,
        collection, treatment, storage, transportation, recovery, removal,
        discharge or disposal of Hazardous Materials and all laws and
        regulations with regard to recordkeeping, notification and reporting
        requirements respecting Hazardous Materials.  For purposes of this
        Section 2.2(k), "substantial compliance" shall mean compliance, except
        to the extent that failure to comply would not have a material adverse
        effect on AOG.

                Except as set forth in the AOG Disclosure Letter, neither AOG
        nor any of its Subsidiaries is subject to any order or decree of or has
        received, within the past five years, any notice from any governmental
        agency with respect to any alleged violation by AOG or any of its
        Subsidiaries of, or the incurrence of any remedial obligation by AOG or
        any of its Subsidiaries under, any applicable federal, state or local
        environmental or health and safety statutes and regulations, which in
        any instance is material to AOG.

                (l) Certain Agreements.  Except as disclosed in the AOG
        Commission Filings filed prior to the date of this Agreement or as
        disclosed in the AOG Disclosure Letter or as provided under this
        Agreement, neither AOG nor any of its Significant Subsidiaries is a
        party to any oral or written (i) agreement with, or obligation to, any
        executive officer or key employee of AOG or any of its Significant
        Subsidiaries (A) for any term of employment or guaranteed compensation
        of such person by AOG or any of its Significant Subsidiaries beyond a
        period of three months or (B) the benefits of which are contingent, or
        the terms of which are materially altered, upon the occurrence of a
        transaction involving AOG of the nature contemplated in this Agreement,
        (ii) agreement or plan, including the AOG Stock Incentive Plan, any of
        the benefits of which will be increased, or the vesting of benefits
        which will be accelerated, by the occurrence of the transactions
        contemplated in this Agreement or the value of which benefits will be
        calculated on the basis of the transactions contemplated by this
        Agreement.

                (m) Voting Requirements.  The affirmative vote of the holders of
        a majority of the outstanding shares of AOG Common Stock is the only
        vote of the holders of any class or series of the capital stock of AOG
        necessary to approve this Agreement and the Merger.

                (n) Insurance.  The AOG Disclosure Letter sets forth all
        material policies of insurance currently in effect relating to the
        business or operations of AOG and its Significant Subsidiaries.





                                      -16-
<PAGE>   21
                (o) Title to Property.  Except as set forth in the AOG
        Disclosure Letter or in the AOG Commission Filings, AOG and each of its
        Significant Subsidiaries have good and indefeasible title to all of
        their material real properties purported to be owned in fee and good
        title to all their other material assets, free and clear of all
        mortgages, liens, charges and encumbrances other than Permitted Liens.

                (p) Utility Status.  Neither AOG nor any of its Subsidiaries is
        a "holding company," a "subsidiary company" of a "holding company," an
        "affiliate" of a "holding company" or a "public utility," within the
        meaning of PUHCA.

                (q) Ownership of KNE Common Stock.  Neither AOG nor any of its
        Subsidiaries, nor to the knowledge of AOG, any of their respective
        affiliates or associates (as such terms are defined under the Exchange
        Act), (i) beneficially owns, directly, or indirectly, or (ii) are
        parties to any agreement, arrangement or understanding for the purpose
        of acquiring, holding, voting or disposing of, in each case, shares of
        capital stock of KNE, which in the aggregate represent 10% or more of
        the outstanding shares of capital stock of KNE entitled to vote
        generally in the election of directors.


                                  ARTICLE III

                  COVENANTS OF AOG PRIOR TO THE EFFECTIVE TIME

        3.1  Conduct of Business by AOG Pending the Merger.  AOG covenants and
agrees that, from the date of this Agreement until the Effective Time, unless

                (e) Neither AOG nor any of its Subsidiaries shall take, and AOG
        will use its reasonable efforts to prevent any affiliate of AOG from
        taking, any action that, in the judgment of Arthur Andersen & Co., AOG's
        independent auditors, would cause the Merger not to be treated as a
        "pooling of interests" for accounting purposes or as a reorganization
        within the meaning of Section 368(a) of the Code;

                (f) AOG shall, and shall cause its Subsidiaries to, perform
        their respective obligations under any contracts and agreements to which

encourage submission of proposals or offers from any person or entity (other
than KNE) relating to any merger, acquisition or purchase of all or (other than
in the ordinary course of business) a portion of the assets of, or any equity
interest in, AOG or any of its Significant Subsidiaries or any business
combination with AOG or any of its Significant Subsidiaries (collectively, an
"AOG Acquisition Transaction") or participate in any negotiations regarding, or
furnish to any other person any information with respect to AOG for the purposes
of, or otherwise cooperate in any way with, or assist or participate in,

properties or assets to a third party; (ii) AOG may engage in discussions or
negotiations with a third party; (iii) following the receipt of a proposal for
an AOG Acquisition Transaction, the Board of Directors of AOG may withdraw,
modify or amend its recommendation to the stockholders of AOG regarding approval
of the Merger and this Agreement and discontinue the solicitation of proxies in
favor of such adoption and approval; and (iv) following receipt of a proposal
for an AOG Acquisition Transaction, AOG may take and disclose to its
stockholders a position contemplated by Rule 14e-2 under the Exchange Act or
otherwise make appropriate disclosures to AOG's stockholders, but in each case
referred to in the foregoing clauses (i) through (iv), only to the extent that
the Board of Directors of AOG concludes in good faith, after receipt of advice
from its outside financial advisors and legal counsel, that such action is
necessary for the Board of Directors of AOG to act in a manner which is
consistent with its fiduciary obligations under applicable law.  AOG shall
promptly notify KNE (orally and in writing) if any such proposal or offer, or
any inquiry or contact with any person with respect thereto, is made.

        3.3  Access to Information; Confidentiality.  From the date hereof to

their officers, directors, employees and representatives to, afford the
representatives of KNE complete access during normal business hours to its
officers, employees, representatives, properties, books and records, and shall
furnish KNE all financial, operating and other data and information as KNE,
through its representatives, reasonably may request; provided, however, that
notwithstanding the foregoing provisions of this Section 3.3 or any other
provision of this Agreement, AOG shall not be required to provide to KNE any
information that is the subject of a confidentiality agreement and that relates
primarily to a party other than AOG, its Subsidiaries or a former Subsidiary of
AOG.

Subsidiaries or its or their representatives in connection with the transactions
contemplated hereby except (i) as required by law; (ii) for disclosure to
officers, directors, employees and representatives of AOG and its Subsidiaries

reasonable efforts to cause each stockholder who, in the opinion of counsel for
AOG, is an "affiliate" of AOG to enter into an agreement on the Closing Date
substantially in the form of Exhibit 3.4.

available to KNE at a reasonable time prior to any filing deadline and, prior to
making such Critical Filing, AOG shall confer with KNE on the matters set forth
therein.  Copies of filed Critical Filings shall be furnished to KNE promptly
upon filing.  As used in this Agreement, an AOG Critical Filing shall mean any
filing by AOG or its Subsidiaries with the Federal Energy Regulatory Commission
("FERC") or any state utility commission or state or local public body having
jurisdiction over the gas pipeline or gas storage businesses and operations of
AOG or its Significant Subsidiaries which would (i) increase or seek to increase
a tariffed rate by more than 20%, (ii) seek abandonment of any service, or any
facility necessary to the performance of, any service accounting for more than

        take all other action reasonably necessary to secure a vote of its
        stockholders in favor of such approval; provided that the recommendation
        of the Board of Directors may be withdrawn, modified or amended, and the
        actions required in clauses (ii) and (iii) hereof may be suspended, to
        the extent that the Board of Directors determines in good faith, after
        receipt of advice from its outside financial advisors and legal counsel,
        that the Board of Directors is required to do so in the exercise of its
        fiduciary duties.

                (c) Notwithstanding anything to the contrary in this Agreement,
        if the Board of Directors of AOG or KNE, as the case may be, determines
        in good faith, after receipt of advice from its outside financial
        advisors and legal counsel, that the Board of Directors is required in
        the exercise of its fiduciary duties to withdraw, modify or amend its
        recommendation, or suspend any action described in clauses (ii) and
        (iii) of Section 5.3(a) or 5.3(b), such withdrawal, modification,
        amendment or suspension of action shall not constitute a breach of this
        Agreement.

        5.4  Filings; Consents; Reasonable Efforts.  Subject to the terms and
conditions of this Agreement, AOG and KNE shall (i) make all necessary filings
with respect to the Merger and this Agreement under the HSR Act, the Securities
Act, the Exchange Act and applicable state takeover laws, blue sky or similar
securities laws and shall use all reasonable efforts to obtain required
approvals and clearances with respect thereto; (ii) obtain all consents,
waivers, approvals, authorizations and orders required in connection with the
authorization, execution and delivery of this Agreement and the consummation of
the Merger; and (iii) take, or cause to be taken, all appropriate action, and
do, or cause to be done, all things necessary, proper or advisable to consummate
and make effective as promptly as practicable the transactions contemplated by
this Agreement.

        5.5  Notification of Certain Matters.  AOG shall give prompt notice to
KNE, and KNE shall give prompt notice to AOG, orally and in writing, of (i) the
occurrence, or failure to occur, of any event which occurrence or failure would
be likely to cause any representation or warranty contained in this Agreement to
be untrue or inaccurate at any time from the date hereof to the Effective Time,
(ii) any material failure or reasonably likely inability of AOG or KNE, as the
case may be, or any officer, director, employee or agent thereof, to comply with
or satisfy any covenant, condition or agreement to be complied with or satisfied
by it hereunder, and (iii) any fact or event that would make it necessary to
amend the Registration Statement or the Proxy Statement in order to render the
statements therein not misleading or to comply with applicable law.

        5.6  Agreement to Defend.  In the event any claim, action, suit,
investigation or other proceeding by any governmental body or other person or
other legal or administrative proceeding is commenced that questions the
validity or legality of the transactions contemplated hereby or seeks damages in
connection therewith, whether before or after the Effective Time, the parties
hereto agree to cooperate and use their reasonable efforts to defend against and
respond thereto.

        5.7  Expenses.  All costs and expenses incurred in connection with this
Agreement and the transactions contemplated hereby shall be paid by the party
incurring such expenses.  Notwithstanding the provisions of the immediately
preceding sentence, (i) if this Agreement is terminated by KNE pursuant to
Section 7.1(e), then AOG shall promptly, but in no event later than three
business days after written request by KNE, pay to KNE an amount equal to
$7,000,000 in immediately available funds; and (ii) if this Agreement is
terminated by AOG pursuant to Section 7.1(f), then KNE shall promptly, but in no
event later than three business days after written request by AOG, pay to AOG an
amount equal to $7,000,000 in immediately available funds. Notwithstanding the
foregoing,





                                      -23-
<PAGE>   28
AOG shall not be required to pay such amount to KNE if the AOG Board of
Directors, Goldman Sachs and Cabot Corporation support the Merger in all
respects, but this Agreement is not approved by the AOG stockholders, and KNE
shall not be required to pay such amount to AOG if the KNE Board and Petrie
Parkman & Co., Inc. support the approval of the issuance by KNE of the KNE
Common Stock pursuant to this Agreement and the Charter Amendment in all
respects, but such matters are not approved by the KNE stockholders.

        5.8  KNE's Board of Directors, Officers and Committees.  KNE's Board of
Directors will take action to increase the number of directors comprising the
full Board of Directors of KNE at the Effective Time to 14 persons and the
directors of KNE shall elect as of the Effective Time four persons designated by
AOG to fill the vacancies created by the increase in the number of directors
prior to the Effective Time.  The designees and their term of office and certain
new officers of KNE as of the Effective Time are set forth on Exhibit 5.8.  If,
prior to the Effective Time, any such designees shall decline or be unable to
serve, AOG or KNE, as the case may be, shall designate another person to serve
in such person's stead.  KNE's Board of Directors will also take action to cause
the election of an AOG designee to the audit and compensation committees of the
Board of Directors of KNE.  KNE's Board of Directors will also take action to
cause a designee of Cabot Corporation to be elected as of the Effective Time as
an advisory director of KNE.  In addition, the Board of Directors of KNE will
take action to establish a Management Committee consisting of four designees as
set forth on Exhibit 5.8.

        5.9  Indemnification.

                (a) AOG shall, and from and after the Effective Time, KNE and
        the Surviving Corporation shall, to the fullest extent permitted under
        applicable law, defend, indemnify and hold harmless each person who is
        now, or has been at any time prior to the date hereof or who becomes
        prior to the Effective Time, an officer or director of AOG or any of its
        Subsidiaries (each, an "Indemnified Party" and, collectively, the
        "Indemnified Parties") against (i) all costs or expenses (including
        reasonable attorneys' fees), judgments, fines, losses, claims, damages,
        liabilities and amounts paid in settlement in connection with any claim,
        action, suit, proceeding or investigation, whether civil, administrative
        or investigative, based in whole or in part on, or arising in whole or
        in part out of, the fact that such person is or was an officer or
        director, whether pertaining to any matter existing or occurring at or
        prior to the Effective Time and whether asserted or claimed prior to, or
        at or after, the Effective Time (collectively, the "Indemnified
        Liabilities"); and (ii) all Indemnified Liabilities based in whole or in
        part on, or arising in whole or in part out of, or pertaining to, this
        Agreement, the Merger or the transactions contemplated hereby.  The
        Indemnified Parties shall be entitled to the indemnification provided
        herein whether such Indemnified Liabilities shall be based on their own
        negligence, whether such persons are solely, concurrently or
        comparatively negligent, strict liability or any other theory of
        recovery.  AOG (or after the Effective Time, KNE and the Surviving
        Corporation) will be entitled to participate in and, to the extent that
        it may wish, to assume the defense of any action, with counsel
        reasonably satisfactory to the Indemnified Party but, if any Indemnified
        Party believes that, by reason of an actual or potential conflict of
        interest, it is advisable for such Indemnified Party to be represented
        by separate counsel, or if AOG (or after the Effective Time, KNE and the
        Surviving Corporation) shall fail to assume responsibility for such
        defense, such Indemnified Party may retain counsel reasonably
        satisfactory to AOG (or after the Effective Time, KNE and the Surviving
        Corporation) who will represent such Indemnified Party, and AOG (or
        after the Effective Time, KNE and the Surviving Corporation) shall pay
        all reasonable fees and disbursements of such counsel promptly as
        statements therefor are received to the full extent permitted by
        applicable law upon receipt of any undertaking contemplated by Section
        145(e) of the DGCL or Section 17-6305(e) of the KGCC, as the case may
        be.  The Indemnified Party and AOG (or after the Effective Time, KNE and
        the Surviving Corporation) will cooperate with each other and use all
        reasonable efforts to assist each other in the vigorous defense of any
        such matter; provided, however, that neither AOG, KNE nor the Surviving
        Corporation shall be liable for any settlement of any claim effected
        without its written consent, which consent, however, shall not be
        unreasonably withheld.  Any Indemnified Party wishing to claim
        indemnification under this Section 5.9, upon learning of any such claim,
        action, suit, proceeding or investigation, shall promptly notify AOG,
        KNE or the Surviving Corporation, as applicable (but the failure





                                      -24-
<PAGE>   29
        to be so notified by an indemnifying party shall not relieve it
        from any liability which it may have under this Section 5.9 except to
        the extent such failure prejudices such party).  The indemnifying
        parties shall be required to pay for only one law firm selected by the
        Indemnified Parties as a group in accordance with the foregoing
        provisions with respect to each such matter unless there is, under
        applicable standards of professional conduct, a conflict in any
        significant issue between the positions of any two or more Indemnified
        Parties.

                (b) For a period of six years after the Effective Time, KNE
        shall, to the extent commercially practicable, make all reasonable
        efforts to cause to be maintained in effect the current policies of
        directors' and officers' liability insurance maintained by AOG, or such
        substitute policies of at least the same coverage and amounts and terms
        and conditions which are no less advantageous, with respect to claims
        arising from the facts or events which occurred before the Effective
        Time, excluding pending and prior litigation or claims that would have
        been required to have been reported on or prior to the Effective Time
        under such current AOG policies and which pending and prior litigation
        or claims were not timely reported under such policies.  As a condition
        precedent to the obligation of KNE to maintain or obtain such policies,
        AOG shall cooperate in the seeking of such insurance.

                (c) Nothing in this Section 5.9 shall give rise to any right to
        indemnification for the malfeasance or willful misfeasance of any
        person. This Section 5.9 is intended to be for the benefit of, and shall
        be enforceable by, each Indemnified Party, his heirs and his
        representatives.

        5.10  AOG Employee Benefits.

                (a) From and after the Effective Time until January 1, 1995, KNE
        and AOG agree that any AOG Pension Plan shall be continued separately
        without change, except for (i) changes required by applicable law, and
        (ii) changes not adverse to the AOG Employees (as hereinafter defined),
        for the benefit of, and participation therein shall be continue to be
        made available to the AOG Employees; provided, however, that the
        employer matching contributions to be made to each such plan on behalf
        of an AOG Employee who is a participant shall be, as a percentage of
        such participant's contributions, at least equal to the rate at which
        employer matching contributions for participants in such plan were made
        by AOG for the plan year ending in 1993, subject to compliance with the
        terms of each such AOG Pension Plan.

                (b) From and after the Effective Time until January 1, 1995, KNE
        and AOG agree that the AOG Benefit Plans (other than any AOG Pension
        Plans) existing as of the Effective Time shall be continued without
        change for the benefit of the AOG Employees, except for (i) changes
        required by applicable law, and (ii) changes not adverse to the AOG
        Employees.

                (c) From and after the Effective Time until January 1, 1995, KNE
        and AOG agree that the AOG benefit policies, practices and programs
        existing as of the Effective Time shall be continued without change for
        the benefit of the AOG Employees, except for (i) changes required by
        applicable law, and (ii) changes not adverse to the AOG Employees.

                (d) In the event that an AOG Employee is transferred or
        reassigned from AOG or any AOG Significant Subsidiary to an employment
        status with KNE or any Significant Subsidiary (other than AOG) and is no
        longer covered under any of the benefit plans, policies, practices or
        programs described in the preceding paragraphs of this Section 5.10,
        such individual shall be afforded coverage under the KNE Benefit Plans
        and benefit policies, practices or programs that are available to
        similarly situated KNE employees on the terms provided in paragraph (e)
        below.

                (e) From and after January 1, 1995, KNE will provide or cause to
        be provided to, the AOG Employees benefit plans, policies and programs
        that are no less favorable than the benefit plans, policies and programs
        that KNE and its Significant Subsidiaries provide to their similarly
        situated employees and shall credit, or cause to be credited, the
        service that such AOG Employees had completed with AOG, the AOG
        Significant Subsidiaries, their predecessors and any previous service in
        connection with any business





                                      -25-
<PAGE>   30
        or assets acquired by AOG as of the Effective Time (but only to
        the extent that any such service was recognized by AOG) and service
        completed with KNE and its Significant Subsidiaries prior to January 1,
        1995, for all purposes under the KNE Benefit Plans, except for (i) the
        accrual of benefits under any defined benefit pension plan, (ii) the
        eligibility to participate in, or receive benefits under, any portion of
        a welfare benefit plan which provides post-retirement medical, dental or
        other health benefits, and (iii) any allocation of contributions under
        any defined contribution pension plan for any plan year ending before
        the earlier of (A) the date that such AOG Employee is transferred or
        reassigned from AOG or any AOG Significant Subsidiary to an employment
        status with KNE or any Significant Subsidiary (other than AOG) or (B)
        January 1, 1995.  Further, with respect to any KNE Benefit Plan which
        provides medical, dental or other health benefits, KNE shall, or cause
        such plan to, waive any pre-existing conditions or limitations
        thereunder applicable to the AOG Employees and their dependents to the
        extent that an AOG Employee or dependent's condition would not have
        operated as a preexisting condition or would not have been subject to
        limitation under any similar AOG Benefit Plan.

                (f) The term "AOG Employees" shall mean those individuals who
        are employed by AOG or any AOG Significant Subsidiary immediately prior
        to the Effective Time and shall include those individuals employed by
        AOG or any AOG Significant Subsidiary (or their successors) on or after
        the Effective Time. KNE agrees to effect the removal of restrictions
        applicable to restricted AOG Common Stock issued under the AOG Stock
        Incentive Plan promptly upon the lapse of such restrictions in
        accordance with the terms of such grant and the AOG Stock Incentive
        Plan.

                (g) KNE shall guarantee all obligations of AOG and the AOG
        Significant Subsidiaries arising under any AOG Benefit Plan, including,
        without limitation, any severance plan, policy or agreement existing as
        of the Effective Time.

        5.11  Standstill Agreement and Registration Rights Agreement.  AOG's
agreements and obligations under its Standstill Agreement with its principal
stockholder, Cabot Corporation, will be terminated on or before the Closing Date
and KNE will enter into on the Closing Date a Registration Rights Agreement in
the form of Exhibit 5.11 with each "affiliate" of AOG or KNE who will hold at
the Effective Time one percent (1%) or more of the KNE Common Stock outstanding.

        5.12  Tax Opinion.  KNE covenants and agrees that during the two year
period following the Effective Time it will not cause or permit the Surviving
Corporation to discontinue its historic business or, in the alternative, cease
to use a significant portion of its historic business assets in a business.

        5.13  Stockholders' Agreements.  AOG has delivered to KNE agreements
from certain key stockholders of AOG whereby such persons agree to vote in favor
of the adoption and approval of this Agreement and in favor of the Merger,
subject to the terms and conditions of this Agreement.

        5.14  AOG Stock Options.

                (a) KNE agrees to assume, effective as of the Effective Time,
        each AOG Option (whether or not vested) which remains as of such date
        unexercised in whole or in part and to substitute shares of KNE Common
        Stock as purchasable under such assumed option ("Assumed Option"), with
        such assumption and substitution to be effected as follows:

                        (i)  The Assumed Option shall not give the optionee
                additional benefits which he did not have under the AOG Option
                before such assumption;

                        (ii)  The number of shares of KNE Common Stock
                purchasable under any Assumed Option shall be equal to the
                number of whole shares of KNE Common Stock that the holder of
                the AOG Option being assumed would have received upon
                consummation of the Merger had such AOG Option been exercised
                immediately prior to the Merger;





                                      -26-
<PAGE>   31
                        (iii)  The per share option price of the Assumed Option
                shall be equal to the per share option price of the AOG Option
                divided by 0.47; and

                        (iv)  The Assumed Option shall provide the optionee with
                the same benefit rights which he had under the AOG Option before
                such assumption.

                (b) As soon as practicable after the Effective Time, KNE shall
        deliver to the holders of AOG Options appropriate agreements evidencing
        its assumption of such options.

                (c) Prior to the Effective Time, KNE shall file a registration
        statement on Form S-8, with respect to the shares of KNE Common Stock
        issuable in respect of the Assumed Options and KNE shall use its best
        efforts to cause such registration statement to become effective
        promptly after the Effective Time and to maintain the effectiveness of
        such registration statement (and maintain the current status of the
        prospectus or prospectuses contained therein) for so long as such
        Assumed Options remain outstanding.  So long as any holder of an Assumed
        Option shall be subject to the reporting requirements under Section
        16(a) of the Exchange Act, KNE shall cause the AOG Stock Incentive Plan
        to be administered in a manner that complies with Rule 16b-3 promulgated
        under the Exchange Act.

        5.15  AOG Warrants.

                (a) KNE agrees to assume, effective as of the Effective Time, 
        each AOG Warrant which remains as of such date unexercised in whole or
        in part and to substitute shares of KNE Common Stock as purchasable
        under such assumed warrant ("Assumed Warrants"), with such assumption
        and substitution to be effected as follows:

                        (i)  The Assumed Warrant shall not give the holder
                additional benefits which it did not have under the AOG Warrant
                before such assumption;

                        (ii)  The number of shares of KNE Common Stock
                purchasable under any Assumed Warrant shall be equal to the
                number of shares of KNE Common Stock that the holder of the AOG
                Warrant being assumed would have received upon consummation of
                the Merger had such AOG Warrant been exercised immediately prior
                to the Merger;

                        (iii)  The per warrant exercise price of the Assumed
                Warrant shall be equal to the per warrant exercise price of the
                AOG Warrant divided by 0.47; and

                        (iv)  The Assumed Warrant shall provide the holder with
                the same benefit rights which the holder had under the AOG
                Warrant before such assumption.

                (b) On the Closing Date, KNE shall deliver to the holders of
        Assumed Warrants appropriate agreements evidencing its assumption of
        such Assumed Warrants and related registration rights (including all
        rights under that certain Warrant Share Registration Rights Agreement
        dated November 19, 1988, by and between AOG and Cabot Corporation).

        5.16  Registration Statement on Form S-3.  On or prior to the Closing
Date, KNE shall file the registration statement on Form S-3 described in the
Share Transfer and Registration Agreement provided for in Section 3.4 hereof. 
KNE shall use its best efforts to cause such registration statement to become
effective on or before the Closing Date.  KNE shall make such registration
statement available to all "affiliates" of KNE and AOG who will beneficially own
more than one percent (1%) of the issued and outstanding shares of KNE Common
Stock immediately after the Effective Time.

                                   ARTICLE VI

                                   CONDITIONS

        6.1  Conditions to Obligation of Each Party to Effect the Merger.  The
respective obligations of each party to effect the Merger shall be subject to
the fulfillment at or prior to the Closing Date of the following conditions:

                (a) This Agreement and the Merger shall have been approved and
        adopted by the requisite vote of the stockholders of AOG, and the
        issuance by KNE of the KNE Common Stock contemplated by this Agreement
        and the Charter Amendment shall have been approved by the stockholders
        of KNE, in each case as may be required by law, by the rules of the New
        York Stock Exchange and by any applicable provisions of their respective
        charters or bylaws;

                (b) The waiting period (and any extension thereof) applicable to
        the consummation of the Merger under the HSR Act shall have expired or
        been terminated;

                (c) No order shall have been entered and remain in effect in any
        action or proceeding before any foreign, federal or state court or
        governmental agency or other foreign, federal or state regulatory or
        administrative agency or commission that would prevent or make illegal
        the consummation of the Merger;

                (d) The Registration Statement shall be effective on the Closing
        Date, and all post-effective amendments filed shall have been declared
        effective or shall have been withdrawn; and no stop-order suspending the
        effectiveness thereof shall have been issued and no proceedings for that
        purpose shall have been initiated or, to the knowledge of the parties,
        threatened by the Commission;

                (e) There shall have been obtained any and all material permits,
        approvals, qualifications and consents of securities or blue sky
        commissions of any jurisdiction, the PUC, the PSC and of any other
        governmental body or agency, that reasonably may be deemed necessary so
        that the consummation of the Merger and the transactions contemplated
        thereby will be in compliance with applicable laws, the failure to

                   SHARE TRANSFER AND REGISTRATION AGREEMENT

        THIS SHARE TRANSFER AND REGISTRATION AGREEMENT (this "Agreement"), made
and entered into as of ________________________, 1994, by and between K N
Energy, Inc., a Kansas corporation ("KNE"), and the undersigned (the
"Stockholder"),

                              W I T N E S S E T H:

        WHEREAS, the Stockholder beneficially owns shares of Common Stock of
American Oil and Gas Corporation, a Delaware corporation ("AOG");

        WHEREAS, KNE, and its wholly-owned subsidiary ("Sub") and AOG have
entered into an Agreement of Merger dated as of March, 1994 (the "Merger
Agreement"), providing for the merger (the "Merger") of Sub with and into AOG
with the issued and outstanding shares of Common Stock of AOG being converted
into shares of Common Stock of KNE.  The shares of Common Stock of KNE received
in the Merger are hereinafter referred to as the "KNE Shares";

        WHEREAS, KNE has been advised that the Stockholder is an "affiliate" of
AOG, as that term is defined for purposes of paragraphs (c) and (d) of Rule 145
promulgated by the Securities and Exchange Commission (the "SEC") under the
Securities Act of 1933 (the "Act");

        WHEREAS, the Merger is conditional upon, among other things, KNE's
receipt of an undertaking from the Stockholder restricting the disposition of
the Stockholder's KNE Shares received by the Stockholder pursuant to the Merger
such that the Merger will be treated as a pooling of interests under generally
accepted accounting principles, and the Stockholder desires to deliver such
undertaking hereby; and

        WHEREAS, KNE desires to grant the Stockholder certain rights to the
registration under the Act of up to 1,500,000 KNE Shares received by the
Stockholder pursuant to the Merger (the "Subject Shares"), generally so as to
permit the Stockholder to dispose of the Subject Shares from time to time in
market transactions without constraint by the volume limitations imposed by
Rules 144(e) and 145(d) promulgated by the SEC under the Act and to provide
Stockholder with similar liquidity provided other affiliated stockholders of
AOG;

        NOW, THEREFORE, for and in consideration of the premises and the mutual
agreements contained herein, the parties hereto agree as follows:





<PAGE>   43
                                   ARTICLE I
                         Representations and Warranties

        1.01  Representations of the Stockholder.  The Stockholder represents
and warrants to KNE that:

                (a) the Stockholder has the requisite power and authority to
        enter into and perform this Agreement;

                (b) since [date - at least 30 days in advance of the effective
        date of the Merger] to and including the date hereof, the Stockholder
        has not sold, transferred or otherwise disposed of any shares of Common
        Stock of AOG; and

                (c) the Stockholder will not make any sale, transfer or other
        disposition of all or any part of the KNE Shares in violation of the Act
        or the rules and regulations thereunder, including, without limitation,
        Rule 145.

        1.02  Representations of KNE.  KNE represents and warrants to the
Stockholder that:

                (a) KNE has the requisite power and authority to enter into and
        perform this Agreement; and

                (b) the execution, delivery and performance of this Agreement
        have been duly authorized by all necessary corporate action on the part
        of KNE, and this Agreement has been duly executed by a duly authorized
        officer on behalf of KNE.


                                   ARTICLE II
                             Transfer Restrictions

        2.01  Restrictions on Disposition of Subject Shares.  Prior to the
Expiration Date (as hereinafter defined), the Stockholder agrees not to contract
to sell, sell or otherwise transfer or dispose of any of the KNE Shares or any
interest therein.  For purposes of this Agreement, the term "Expiration Date"
shall mean the date that KNE first publishes financial statements (the "Combined
Financials") which reflect at least thirty (30) days of combined operations of
KNE and AOG.  Notwithstanding the foregoing, and without regard to the
Expiration Date, if the SEC notifies the Stockholder of a scheduled hearing for
the purpose of determining





                                      -2-
<PAGE>   44
whether or not the Stockholder will be deemed to be a "public utility holding
company" of KNE under the Public Utility Holding Company Act of 1935, then the
Stockholder may contract to sell, sell or otherwise transfer or dispose of any
of the Subject Shares at any time after the 60th day preceding such scheduled
hearing.

        2.02  Combined Financials.  KNE agrees to publish the Combined
Financials without undue delay and thereupon to notify the Stockholder of the
occurrence of the Expiration Date.

        2.03  Legends on Certificates.  Except with respect to the Subject
Shares included in the "shelf" registration statement described in Article III
hereof, KNE may give stop transfer instructions to its transfer agent with
respect to the KNE Shares and place on each certificate representing any KNE
Shares (and any substitution therefor) a legend stating in substance:

        "The securities represented by this certificate were issued in a
        transaction to which Rule 145 promulgated under the Securities Act of
        1933 (the "Act") applies and may be sold, transferred or otherwise
        disposed of only in compliance with the limitations of such Rule 145,
        upon receipt by K N Energy, Inc. of an opinion of counsel acceptable to
        it that some other exemption from registration under the Act is
        available, or pursuant to a registration statement under the Act.  Such
        securities may also be subject to restrictions on transfer pursuant to
        Section 2.01 of a Share Transfer and Registration Rights Agreement
        between KNE and the holder hereof."

        The legend set forth above shall be removed by delivery of substitute
certificates without such legend, and the related stop transfer instructions
shall be lifted forthwith, provided that the KNE Shares have been registered
under the Act for sale, transfer, or other disposition by the Stockholder or on
the Stockholder's behalf, whether pursuant to Article III hereof or otherwise,
or the Stockholder has delivered to KNE an opinion of counsel reasonably
acceptable to KNE, to the effect that an exemption from registration under the
Act is available with respect thereto.


                                  ARTICLE III
                               Shelf Registration

        3.01  Participation in Shelf Registration.  (a) Pursuant to Section 5.16
of the Merger Agreement, KNE shall prepare and file with the SEC a continuous or
"shelf" registration statement (as the same may be amended, the "Registration
Statement") pursuant to Rule 415 under the Act, respecting the sale from time to
time of up to the number of Subject Shares issued to each AOG affiliate in the
Merger, who will beneficially own more than one percent (1%) of the issued and
outstanding shares of Common Stock of KNE immediately after consummation of the
Merger, in one or more transactions (which may involve block





                                      -3-
<PAGE>   45
transactions) on the New York Stock Exchange, in special offerings, exchange
distributions and/or secondary distributions pursuant to and in accordance with
the rules of the New York Stock Exchange, in the over-the-counter market, other
brokerage transactions, negotiated transactions, underwritten firm commitment
or best efforts offerings, or a combination of such methods of sale, at market
prices prevailing at the time of sale, at prices related to such market prices
or at negotiated prices. Except for the Subject Shares, KNE shall have no
obligation to register under the Act any of the KNE Shares for sale, transfer
or other disposition by the Stockholder, except pursuant to that certain
affiliate Registration Rights Agreement of even date herewith between the
parties hereto.

        (b)  KNE shall use its best efforts to cause the Registration Statement
to (i) become effective on or before the Closing Date (as defined in the Merger
Agreement) and (ii) remain effective continuously until Stockholder does not own
KNE Shares aggregating ten percent (10%) of the then outstanding KNE Shares as
shown by the most recent report or statement published by KNE.

        3.02  Registration Procedures.  KNE shall, as expeditiously as possible:

        (a)  prepare and file with the SEC such amendments and supplements to
the Registration Statement and each prospectus used in connection therewith as
may be necessary to keep the Registration Statement effective for the period
specified in Section 3.01(b) and as may be necessary to comply with the
provisions of the Act with respect to the disposition of the Subject Shares
covered by the Registration Statement in accordance with the intended method of
disposition set forth in the Registration Statement;

        (b)  furnish to the Stockholder and to each broker or dealer acting on
behalf of the Stockholder such number of copies of the Registration Statement as
originally filed and each amendment or supplement thereto and each prospectus
included therein (including any preliminary prospectus and each document
incorporated by reference therein to the extent then required by the rules and
regulations of the SEC) as such persons may reasonably request in order to
facilitate the public sale or other disposition of the Subject Shares covered by
the Registration Statement, and, upon the Stockholder's request, furnish each
such prospectus to the New York Stock Exchange at such times and in such
quantities as may be necessary to comply with Rule 153 under the Act;





                                      -4-
<PAGE>   46
        (c)  use its best efforts to register or qualify the Subject Shares
covered by the Registration Statement under the securities or blue sky laws of
such jurisdictions within the United States as the Stockholder shall reasonably
request and to take all necessary action to keep such registration or
qualification effective for the period specified in Section 3.01(b); provided,
however, that KNE shall not be required to qualify to transact business as a
foreign corporation in any jurisdiction in which it would not otherwise be
required to be so qualified or to take any action which would subject it to
general service of process in any such jurisdictions which it is not then so
subject; and

        (d)  immediately notify the Stockholder, at any time when a prospectus
relating thereto is required to be delivered under the Act, of the happening of
any event as a result of which the prospectus contained in the Registration
Statement, as then in effect, includes an untrue statement of a material fact or
omits to state any material fact required to be stated therein or necessary to
make the statements therein not misleading in the light of the circumstances
then existing (in which case, KNE shall as soon as practicable in view of the
circumstances giving rise to such misstatement or omission provide the
Stockholder with revised or supplemental prospectuses and if so requested by
KNE, the Stockholder shall promptly take action to cease making any offers of
Subject Shares until receipt and distribution of such revised or supplemental
prospectuses).

        In connection with the registration of any Subject Shares hereunder, the
Stockholder will furnish promptly to KNE in writing such information (together
with such supplements as may be necessary from time to time) with respect to
himself or itself and the proposed distribution by him or it as shall be
reasonably necessary in order to ensure compliance with federal and applicable
state securities laws.

        3.03  Expenses.  KNE will pay all expenses incurred by it in complying
with its registration obligations pursuant to Section 3.01 hereof, including,
without limitation, all registration and filing fees, blue sky fees and
expenses, printing expenses, fees and disbursements of counsel and independent
public accountants for KNE, and fees of transfer agents and registrars, but
excluding any selling commissions or discounts allocable to the sale of the
Subject Shares, fees and disbursements of counsel and other representatives for
the Stockholder and any stock transfer taxes payable by reason of the
Stockholder's sale of the Subject Shares, all of which shall be for the
Stockholder's account.

        3.04  Indemnification.

        (a)   KNE shall indemnify and hold harmless the Stockholder, each of its
officers and directors, each statutory underwriter of Subject Shares thereunder
and each person who controls the Stockholder or such underwriter within the
meaning of the Act, against any losses, claims, damages or liabilities
(including reasonable attorneys' fees), joint or several, to which the
Stockholder, its directors or officers, or such underwriter or controlling
person may become





                                      -5-
<PAGE>   47
subject under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
the Registration Statement, any preliminary prospectus or final prospectus
contained therein, or any amendment or supplement thereof, or arise out of or
are based upon the omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, and KNE shall reimburse the Stockholder, its officers and
directors, each such underwriter and each such controlling person for any legal
or other expenses reasonably incurred by them in connection with investigating
or defending any such loss, claim, damage, liability or action; provided,
however, that KNE shall not be liable hereunder in any such case if and to the
extent that any such loss, claim, damage or liability arises out of or is based
upon an untrue statement or alleged untrue statement or omission or alleged
omission so made in conformity with information furnished by the Stockholder,
such underwriter or such controlling person in writing specifically for use in
the Registration Statement or such prospectus.

        (b)  The Stockholder will indemnify and hold harmless KNE, each person
who controls KNE within the meaning of the Act, each officer of KNE who signs
the Registration Statement, and each director of KNE, against any losses,
claims, damages or liabilities (including reasonable attorneys' fees), joint or
several, to which KNE or such officer, director or controlling person may become
subject under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
the Registration Statement, any preliminary prospectus or final prospectus
contained therein, or any amendment or supplement thereof, or arise out of or
are based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, and the Stockholder shall reimburse KNE and each such officer,
director and controlling person for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that the Stockholder
shall be liable hereunder in any such case if and only to the extent that any
such loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission relating
to the Stockholder made in reliance upon and in conformity with information
pertaining to the Stockholder, as such, furnished in writing to KNE by the
Stockholder specifically for use in the Registration Statement or such
prospectus ("Stockholder Information"); and provided, further, that the
liability of the Stockholder hereunder shall not exceed the amount of the
proceeds received by the Stockholder from the sale of the Subject Shares covered
by the Registration Statement.





                                      -6-
<PAGE>   48
        (c)  Promptly after receipt by an indemnified party hereunder of notice
of the commencement of any action, such indemnified party shall, if a claim in
respect thereof is to be made against the indemnifying party hereunder, notify
the indemnifying party in writing thereof, but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party other than under this Section 3.04.  In case any such
action shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate in and, to the extent it shall wish, to assume and
undertake the defense thereof with counsel reasonably satisfactory to such
indemnified party and, after notice from the indemnifying party to such
indemnified party of its election so to assume and undertake the defense
thereof, the indemnifying party shall not be liable to such indemnified party
under this Section 3.04 for any legal expenses subsequently incurred by such
indemnified party in connection with the defense thereof; provided, however,
that if the indemnifying party has failed to assume the defense and employ
counsel or if the interests of the indemnified party reasonably may be deemed to
conflict with the interests of the indemnifying party, then the indemnified
party shall have the right to select a separate counsel and to assume such legal
defense and otherwise to participate in the defense of such action, with the
expenses and fees of such separate counsel and other expenses related to such
participation to be reimbursed by the indemnifying party as incurred.

        (d)  If the indemnification provided for in this Section 3.04 is
unavailable or insufficient to hold harmless an indemnified party in respect of
any losses, claims, damages or liabilities or actions in respect thereof, then
the indemnifying party shall in lieu of indemnifying such indemnified party
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or actions in such proportion as is
appropriate to reflect the relative fault of KNE, on the one hand, and the
Stockholder, on the other, in connection with the statements or omissions which
resulted in such losses, claims, damages, liabilities or actions as well as any
other relevant equitable considerations, including the failure to give any
required notice.  The relative fault shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by KNE, on the one hand, or the Stockholder, on the other,
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.  KNE and the
Stockholder agree that it would not be just and equitable if contribution
pursuant to this subparagraph (d) were determined by pro rata allocation or by
any other method of allocation which does not take account of the equitable
considerations referred to above in this subparagraph (d).  The amount paid or
payable by an indemnified party as a result of the losses, claims, damages,
liabilities or actions in respect thereof referred to above in this subparagraph
(d) shall be deemed to include any legal or other expenses reasonably incurred
by such indemnified party in connection with investigating or defending any such
action or claim.  Notwithstanding the provisions of this subparagraph (d), the
amount that the Stockholder shall be required to contribute shall not exceed the
amount of the proceeds received by the





                                      -7-
<PAGE>   49
Stockholder from the sale of the Subject Shares covered by the Registration
Statement.  No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.


                                   ARTICLE IV
                            Miscellaneous Provisions

        4.01  Binding Effect.  This Agreement and all of the provisions hereof

respective successors and permitted assigns.  Neither this Agreement nor any of
the rights, interests or obligations hereunder shall be assigned by either of
the parties hereto without the prior written consent of the other party, except
that if the Subject Shares are transferred to any affiliate of Stockholder, this
Agreement and the rights and obligations hereunder shall be assignable to such
affiliate with notice to KNE, provided that Stockholder shall remain liable for
all obligations of Stockholder hereunder.  Nothing in this Agreement, express or
implied, is intended to confer upon any person other than the parties hereto and
their respective successors and permitted assigns, any right, benefit or
obligation hereunder.

        4.02  Amendments.  This Agreement may not be modified, amended, altered
or supplemented except by way of a written agreement executed by each of the
parties hereto.  However, either party may waive any condition to the
obligations of the other party hereunder.

        4.03  Notices.  All notices, requests, demands and other communications
required or permitted hereunder shall be in writing and shall be deemed to have

       stockholders of AOG who have executed similar Registration Rights
       Agreements pursuant to Section 5.11 of the Merger Agreement and (ii) KNE

              1.02   Required Registration.  At any time during a period of
five years following the date of consummation of the Merger, the Initiating
Holders may request that the Company effect a registration with respect to the
Registrable Common Stock, as follows:

              (a)    Request for Registration of Common Stock.  In the event
       that the Company shall receive from Initiating Holders a written request
       that the Company effect any registration with respect to all or any part
       but not less than 750,000 shares of the Registrable Common Stock, the
       Company will: (i) promptly give written notice of the proposed
       registration to all other Holders; and (ii) as soon as practicable, use
       its diligent best efforts to effect all such registration, qualification
       and compliance (including, without limitation, the execution of an
       undertaking to file post-effective amendments, appropriate qualification
       under applicable blue sky or other state securities laws and appropriate
       compliance with applicable regulations issued under the Act) as may be
       so requested and as would permit or facilitate the sale and distribution
       of all or such portion of such Registrable Common Stock as is specified
       in such request, together with all or such portion of the Registrable
       Common Stock of any Holder or Holders thereof joining in such request as
       are specified in a written request given within 30 days after receipt of
       such written notice from the Company.

                                    -2-
<PAGE>   54
              (b)    Underwriting.  If the Initiating Holders intend to
       distribute the Registrable Common Stock covered by their request by
       means of an underwriting, they shall so advise the Company as a part of
       their request made pursuant to this Section 1.02 and the Company shall
       include such information in the written notice referred to in Section
       1.02(a)(i).  In such event, the right of any Holder to registration
       pursuant to this Section 1.02 shall be conditioned upon such Holder's
       participation in such underwriting and the inclusion in the underwriting
       of not less than 10% of the Registrable Common Stock held by such Holder
       (unless otherwise mutually agreed by a majority in interest of the
       Initiating Holders and such Holder) to the extent provided herein.

              The Company shall (together with all Holders proposing to
       distribute their Registrable Common Stock through such underwriting)
       enter into an underwriting agreement in customary form with the
       representative of the lead managing underwriter selected for such
       underwriting by a majority in interest of the Initiating Holders and
       approved by the Company, which approval shall not be unreasonably
       withheld and any co-managing underwriters mutually selected for such
       underwriting by a majority-in-interest of the Initiating Holders and the
       Company, the approval of which selection shall not be unreasonably
       withheld by either party.  Notwithstanding any other provision of this
       Section 1.02, if the underwriter determines, in good faith and
       independent of any request by the Company, that marketing factors
       require a limitation of the number of shares to be underwritten, and if
       all directors or officers of the Company who had sought to have any of
       their shares included in such registration shall have withdrawn all such
       shares from registration, the underwriter may limit the number of shares
       of Registrable Common Stock to be included in the registration and
       underwriting to the extent such underwriter deems necessary.  The
       Company shall so advise all Holders, and the number of shares of
       Registrable Common Stock that may be included in the registration and
       underwriting shall be allocated among all Holders thereof in proportion,
       as nearly as practicable, to the respective amounts of Registrable
       Common Stock entitled to inclusion in such registration held by such
       Holders at the time of filing the registration statement.  If any Holder
       of Registrable Common Stock disapproves of the terms of the
       underwriting, such person may elect to withdraw therefrom by written
       notice to the Company, the underwriter and the Initiating Holders and
       the Registrable Common Stock so withdrawn shall also be withdrawn from
       registration but shall be entitled to such registration rights granted
       to such Registrable Common Stock pursuant to this Section 1.02 as may
       thereafter remain in effect.

              The Company and the holders of the Common Stock and of any other
       security of the Company to whom the Company has granted registration
       rights substantially identical to those granted to Holders of
       Registrable Common Stock may include their respective securities for
       their own accounts in such registration if the underwriter so agrees and
       if the number of shares of Registrable Common Stock and other securities
       which would otherwise have

                                    -3-
<PAGE>   55
       been included in such registration and underwriting will not thereby be 
       limited and if such inclusion will not otherwise adversely impact the 
       offering.

              (c)    Expenses of Requested Registration.  The Company shall
       bear all expenses incurred in connection with each registration,
       qualification or compliance pursuant to Section 1.02(a), including,
       without limitation, all registration, filing and qualification fees,
       printing expenses, audit fees and fees and disbursements of counsel for
       the Company and counsel for the underwriters, if any (unless any such
       underwriter pays such counsel fees) (but excluding underwriter's
       commissions, fees and expenses allocable to the Registrable Common Stock
       of the Holders and fees of independent counsel, if any, for the Holders,
       which commissions, fees and expenses and fees of counsel shall be borne
       pro rata (by share) by the Holders electing to participate in such
       requested registration).

              (d)    Limitations on Registration.  Notwithstanding any
       provision to the contrary in this Section 1.02, the Company shall not be
       obligated to take any action to effect any such registration,
       qualification or compliance pursuant to Section 1.02(a) if (i) reputable
       counsel designated by the Company delivers an opinion to such Initiating
       Holders, in form and substance satisfactory to such Initiating Holders,
       to the effect that the Registrable Common Stock specified in the request
       for registration may be sold or distributed as planned by the Initiating
       Holders without registration or (ii) the Company has effected two
       previous registrations pursuant to this Section 1.02(a).  Additionally,
       the Company shall not be obligated  to include in any registration
       statement effected pursuant to this Section 1.02, any shares of
       Registrable Common Stock which are subject to an effective and current
       shelf registration statement under the Share Transfer Agreement.

              1.03   Registration Rights; Company Registration.

              (a)    Registration Initiated by the Company.  In the event the
       Company shall determine to register any shares of KNE Common Stock,
       either for its own account or for the account of a security holder or
       holders exercising their respective demand registration rights (other
       than a shelf registration referred to in Section 1.02(d) or a
       registration relating to stock options or employee benefit plans, the
       Company's dividend reinvestment plan, or the acquisition or purchase by
       or combination by merger or otherwise of the Company of or with another
       company or business entity or partnership or a registration pursuant to
       Section 1.02) the Company will:

                     (i)    promptly give to each Holder written notice thereof
              (which shall include a list of the jurisdictions in which the
              Company intends to attempt to qualify such securities under the
              applicable blue sky or other state securities laws); and

                                  -4-
<PAGE>   56
                     (ii)   include in such registration (and any related
              qualification under blue sky laws or other compliance), and in
              any underwriting involved therein, all the Registrable Common
              Stock specified in a written request or requests, made within 30
              days after receipt of such written notice from the Company, by
              any Holder or Holders of such Registrable Common Stock, except as
              set forth in Section 1.03(b) below.

              (b)    Underwriting.  If the registration of which the Company
       gives notice is for a registered public offering involving an
       underwriting, the Company shall so advise the Holders as a part of the
       written notice given pursuant to Section 1.03(a)(i).  In such event, the
       right of any Holder to registration pursuant to this Section 1.03 shall
       be conditioned upon such Holder's participation in such underwriting and
       the inclusion of such Holder's Registrable Common Stock in the
       underwriting to the extent provided herein.  All Holders proposing to
       distribute their Registrable Common Stock through such underwriting
       shall (together with the Company and the other holders (if any)
       distributing their securities through such underwriting) enter into an
       underwriting agreement in customary form with the underwriter or
       underwriters selected for such underwriting by the Company.
       Notwithstanding any other provision of this Section 1.03, if the
       underwriter determines, in good faith and independent of any request by
       the Company, that marketing factors require a limitation of the number
       of shares to be underwritten, and if all directors or officers of the
       Company who had sought to have any of their shares included in such
       registration shall have withdrawn all such shares from registration, the
       underwriter may limit the number of shares of Registrable Common Stock
       to be included in the registration and underwriting to the extent such
       underwriter deems necessary.  The Company shall so advise all Holders,
       and the number of shares of Registrable Common Stock that may be
       included in the registration and underwriting shall be allocated among
       all Holders thereof in proportion, as nearly as practicable, to the
       respective amounts of Registrable Common Stock entitled to inclusion in
       such registration held by such Holders at the time of filing the
       registration statement.  If any Holder disapproves of the terms of any
       such underwriting, he may elect to withdraw therefrom by written notice
       to the Company and the underwriter.  Any Registrable Common Stock
       excluded or withdrawn from such underwriting shall be withdrawn from
       such registration.

              (c)    Expenses of Registration by the Company.  The Company
       shall bear all expenses incurred in connection with each registration,
       qualification or compliance pursuant to this Section 1.03, including,
       without limitation, all registration, filing and qualification fees,
       printing expenses, audit fees and fees and disbursements of counsel for
       the Company and counsel for the underwriters, if any (unless any such
       underwriter pays such counsel fees) (but excluding underwriter's
       commissions, fees and expenses allocable to the Registrable Common Stock
       of the Holders and fees of independent counsel, if any, for the Holders,
       which commissions, fees and expenses and fees of counsel

                                   -5-

<PAGE>   57
       shall be borne pro rata (by share) by the Holders electing to participate
       in such requested registration).

              (d)    Limitations on Registration.  The Company's obligation to
       effect a registration under Section 1.03(a) shall expire five years from
       the date of consummation of the Merger.  Notwithstanding any provision
       to the contrary in this Section 1.03, the Company shall not be obligated
       to take any action to effect any such registration, qualification or
       compliance pursuant to Section 1.03 if the Company has effected two
       previous registrations pursuant to this Section 1.03.  Additionally, the
       Company shall not be obligated to include in any registration statement
       effected pursuant to this Section 1.03, any shares of Registrable Common
       Stock which are subject to an effective and current shelf registration
       statement under the Share Transfer Agreement.

              1.04   Registration Procedures.  In the case of each
registration, qualification or compliance effected by the Company pursuant to
this Agreement pursuant to which Registrable Common Stock for a Holder is
included therein, the Company will keep such Holder advised in writing as to
the initiation of each registration, qualification and compliance and as to the
completion thereof.  At its expense, the Company will:

              (a)    keep such registration, qualification or compliance
       effective for a period of at least 120 days or until the Holder or
       Holders have completed the distribution described in the registration
       statement relating thereto, whichever first occurs;

              (b)    furnish such number of prospectuses and other documents
       incident thereto as such Holder from time to time may reasonably
       request; and

              (c)    list such Registrable Common Stock on each securities
       exchange (if any) on which the Common Stock is listed.

              1.05   Indemnification.

              (a)    The Company shall, if Registrable Common Stock held by a
       Holder is included in the securities as to which such registration,
       qualification or compliance is being effected, indemnify such Holder,
       each of its officers and directors, and each person controlling such
       Holder, with respect to which registration, qualification or compliance
       has been effected pursuant to Section 1.02 or 1.03, and each
       underwriter, if any, and each person who controls any underwriter,
       against all claims, losses, damages and liabilities (or actions in
       respect thereof) arising out of or based on any untrue statement (or
       alleged untrue statement) of a material fact contained in any
       prospectus, offering circular or other document (including any related
       registration statement, notification or the like) incident to any such
       registration, qualification or compliance, or based on any omission (or
       alleged omission) to state therein a

                                 -6-

<PAGE>   58
       material fact required to be stated therein or necessary to make the 
       statements not misleading, and will reimburse each such Holder, each 
       of its officers and directors, and each person controlling such Holder, 
       each such underwriter and each person who controls any such 
       underwriter, for any legal and any other expenses reasonably incurred 
       in connection with investigating or defending any such claim, loss, 
       damage, liability or action, provided that the Company will not be 
       liable in any such case to the extent that any such claim, loss, damage,
       liability or expense arises out of or is based on any untrue statement 
       or mission based upon written information furnished to the Company by an
       instrument duly executed by such Holder or underwriter and stated to be
       specifically for use therein.  Such indemnity shall remain in full force 
       and effect regardless of any investigation made by or on behalf of such 
       party and shall survive the subsequent transfer of shares of Common 
       Stock by the seller thereof and the transfer of any shares of Common 
       Stock of the Company which were the subject of such registration, 
       qualification or listing.

              (b)    Each Holder will, if Registrable Common Stock held by such
       Holder is included in the securities as to which such registration,
       qualification or compliance is being effected, indemnify the Company,
       each of its directors and officers, each legal counsel and independent
       accountant of the Company, each underwriter, if any, of the Company's
       securities covered by such a registration statement, each person who
       controls the Company or such underwriter within the meaning of the Act,
       and each other Holder registering Registrable Common Stock, each of its
       officers and directors and each person controlling such Holder, against
       all claims, losses, damages and liabilities (or actions in respect
       thereof) arising out of or based on any untrue statement (or alleged
       untrue statement) of a material fact contained in any such registration
       statement, prospectus, offering circular or other document, or any
       omission (or alleged omission) to state therein a material fact required
       to be stated therein or necessary to make the statements therein not
       misleading, and will reimburse the Company, such Holders, such
       directors, officers, persons, underwriters or control persons for any
       legal or any other expenses reasonably incurred in connection with
       investigating or defending any such claim, loss, damage, liability or
       action, in each case to the extent, but only to the extent, that such
       untrue statement (or alleged untrue statement) or omission (or alleged
       omission) is made in such registration statement, prospectus, offering
       circular or other document in reliance upon and in conformity with
       written information furnished to the Company by an instrument duly
       executed by such Holder and stated to be specifically for use therein;
       provided, however, that (i) the obligations of such Holders hereunder
       shall be limited to an amount equal to the proceeds to each such Holder
       of Registrable Common Stock sold as contemplated herein and (ii) the
       indemnity for untrue statements or omissions described above shall not
       apply if the Holder providing such written information provides the
       Company with such additional written information prior to the
       effectiveness of the registration as is required to make the previously
       supplied written information

                                      -7-


<PAGE>   59
       true and complete, together with a description in reasonable detail of 
       the information previously supplied which was untrue or incomplete.

              (c)    Each party entitled to indemnification under this Section
       1.05 (the "Indemnified Party") shall give notice to the party required
       to provide indemnification (the "Indemnifying Party") promptly after
       such Indemnified Party has actual knowledge of any claim as to which
       indemnity may be sought, and shall permit the Indemnifying Party to
       assume the defense of any such claim or any litigation resulting
       therefrom, provided that counsel for the Indemnifying Party, who shall
       conduct the defense of such claim or litigation, shall be approved by
       the Indemnified Party (whose approval shall not unreasonably be
       withheld), and the Indemnified Party may participate in such defense at
       such party's expense, and provided further that the failure of any
       Indemnified Party to give notice as provided herein shall not relieve
       the Indemnifying Party of any obligations it may have otherwise than on
       account of this Section 1.05.  After notice from the Indemnifying Party
       to the Indemnified Party of its election to assume the defense of such
       claim or litigation, the Indemnifying Party will not be liable to such
       Indemnified Party for any legal or other expenses subsequently incurred
       by such Indemnified Party in connection with the defense thereof other
       than reasonable costs of investigation, unless the Indemnifying Party

       unconditional term thereof the giving by the claimant or plaintiff to

 AMERICAN OIL AND GAS CORPORATION                                NEWS RELEASE
 KN ENERGY


                      K N ENERGY AND AMERICAN OIL AND GAS
                          ENTER INTO MERGER AGREEMENT


Lakewood, CO/Houston, TX -- K N Energy, Inc. (NYSE-KNE) and American Oil and
Gas Corporation (NYSE-AOG) jointly announced today they had signed a definitive
merger agreement to combine the two companies.


TRANSACTION STRUCTURE

The contemplated merger will be a tax-free exchange of common stock, in which
0.47 of a share of K N Energy common stock will be exchanged for each
outstanding share of American Oil and Gas.  Following the merger, the combined
company will have approximately 28 million shares of common stock outstanding.

The proposed merger will require approval by the shareholders of both
companies, as well as specific regulatory and lender approvals.  Closing is
anticipated within the next 90 to 120 days.

"We view this important merger as a marriage of two complementary companies
with the ability to capitalize on their respective strengths," said Charles W.
Battey, K N Energy chairman and chief executive officer.  "Shareholders will
benefit as a result of the new company's strong financial position, attractive
dividend yield and prospects for future growth."

"The merger will create a strategic alliance and will better position the
combined company to take advantage of growth opportunities," said David M.
Carmichael, chairman and chief executive officer of American Oil and Gas.  "We
believe the new company will be a significant player in the evolving North
American gas markets by virtue of its strong access to supply and markets."

The merger will combine two geographically distinct gas systems with
complementary supply basins, service territories, and target marketing areas.
The proximity of the two companies' Rocky Mountain and Mid-Continent operating
regions enhances the opportunity to integrate facilities and services, and
compete more effectively in the natural gas industry.

FINANCIAL CONSIDERATIONS

At December 31, 1993, the pro forma combined companies would have had
approximately $1.2 billion in assets, $1.0 billion in annual revenues and $31
million in annual net income.  Also, pro forma combined pre-tax cash flow from
operations, defined as operating income plus depreciation, depletion and
amortization, would have been $123 million.  The merger is expected to be
accounted for as a pooling of interests, in which the resources and the
reported financial statements of the two entities are consolidated.

The parties anticipate the merger will provide substantial operating benefits.
The benefits are expected to increase cash flow from operations and provide for
positive earnings momentum once the combination is completed and the one-time
charges associated with the combination have been absorbed.

The combined entity will have equity capital of approximately $392 million, and
a long-term debt to total capitalization ratio of approximately 45 percent,
which will provide significant financial flexibility.  This ratio compares to
an average long-term debt to total capitalization ratio of 50 percent among
diversified natural gas companies and about 55 percent among natural gas
gathering, transportation and marketing companies.

K N Energy's most recent declared quarterly common stock dividend was $0.24 per
share, payable March 31, 1994; American Oil and Gas does not pay a common stock
dividend.  It is anticipated that the combined company will maintain a $0.24
per share quarterly dividend level on common stock after the merger.

BUSINESS OPPORTUNITIES

The combined company will be a major pipeline participant in the natural gas
gathering, transportation and marketing sector, particularly in the Rocky
Mountain and Mid-Continent regions of the United States.  The combined entity
will market, sell and transport an aggregate of 1.5 billion cubic feet of
natural gas per day -- almost three percent of total United States natural gas
consumption.

GAS SALES AND MARKETING:  For 1993, the total sales of natural gas of the two
companies was approximately 333 billion cubic feet.  K N Energy's traditional
service territory has a high winter heating demand for natural gas, while
American Oil and Gas's service territory has a higher demand in the summer when
natural gas is used for electricity generation and to power irrigation pump
engines.  The balanced load that results from the combined company's strong
year-round demand will enhance market access for producers and provide a
diverse, competitive gas supply for customers.

The combined company will have greater access to multiple pipeline market
centers, or trading hubs, thereby enhancing the ability to market gas to a
broader customer base on the nationwide natural gas pipeline system.  Market
centers are physical pipeline interconnects among a number of pipelines where
natural gas is bought, sold, delivered and transferred for short and long-term
customer needs.  The natural gas industry's use of market centers increased
dramatically during the abnormally cold winter of 1993-1994 and contributed to
the





                                    2  of  6
<PAGE>   3
success of the industry in meeting marketplace demands.  American Oil and Gas's
systems connect with the Waha market center in West Texas and with K N Energy's
Buffalo Wallow market center in the Texas Panhandle.


GAS TRANSPORTATION AND STORAGE:  The combined company will have over 18,700
total miles of transmission and gathering pipeline that serve direct markets
and also interconnect with other major pipelines.  The new company will offer
natural gas shippers greater access to diverse supply regions and to natural
gas markets throughout the United States and, therefore, will be better able to
utilize existing pipeline system capacity.  K N Energy was successful in
increasing the total throughput on its pipeline systems by 70 percent between
1988 and 1993.  The combined management team will focus its efforts on
maximizing throughput on all of the merged company's systems.

In addition, the combined company will have initial core working gas storage
capacity of 28 billion cubic feet, with an additional three billion cubic feet
of high-deliverability salt cavern storage under development.  The locations of
the principal storage fields in southwestern Nebraska and in western Texas
offer customers flexible storage options to meet peaking needs and seasonal
load management requirements.  American Oil and Gas's storage sites are located
near the Waha, Texas market center and are directly connected to K N Energy's
Buffalo Wallow market center through the Red River Pipeline, operated by
American Oil and Gas.

NATURAL GAS GATHERING AND PROCESSING:  The combined company will operate
nonregulated gathering and processing facilities in six Rocky Mountain and
Mid-Continent states.  The company will have operations in some of the largest
and most prolific gas-producing areas in the U.S., stretching from the Wind
River and Powder River Basins in Wyoming, south through the Denver-Julesburg
basin in Colorado, the Anadarko Basin and Hugoton Embayment in Kansas, Oklahoma
and Texas, to the Permian Basin in southwestern Texas.

For 1993, total processing plant hydrocarbon liquid sales of the two companies
were 320 million gallons.  This accounted for approximately 10 percent of 1993
aggregate revenues of the two companies.

CONSOLIDATION EFFICIENCIES:  The combined entity's diversity of operations in
all facets of the natural gas value stream allows it to moderate the potential
risks of any one sector of the industry.  The combined company will attain
economies of scale in operations and will be able to reduce overall
administrative overhead costs, making it a more competitive service provider
from the natural gas wellhead to the burnertip.

MANAGEMENT AND GOVERNANCE

Upon closing of the transaction, Charles W. Battey, chairman and chief
executive officer of K N Energy, will serve as chairman of the board of the
combined company, Larry D. Hall, K N Energy's president and chief operating
officer, will serve as president and chief executive officer of the combined
company, and David M. Carmichael, chairman and chief executive





                                    3  of  6
<PAGE>   4
officer of American Oil and Gas, will serve as vice chairman of the combined
company.  Prior to closing, Dan Dienstbier will continue as president of
American Oil and Gas and will help accomplish the integration of the two
companies.

Also, upon closing, K N Energy's Board of Directors will be increased from 10
to 14 directors, as a result of adding four current directors of American Oil
and Gas.  Cabot Corporation, American Oil and Gas's largest shareholder, will
be represented at board of directors' meetings of the combined company via a
single, non-voting, advisory director.  Cabot owns approximately 35 percent of
the outstanding shares of American Oil and Gas, and would own approximately 15
percent of the outstanding common stock of the combined company at the time of
merger.

OPERATIONS DESCRIPTIONS

K N Energy is a natural gas services company focusing on gas reserves
development, gas gathering, processing, marketing, storage, transportation and
retail gas distribution services.  The Company, with 1,735, employees, operates
in seven states and serves customers, including 232,000 direct retail
customers, through three pipeline systems.

American Oil and Gas operates principally in Texas in the mid-stream segment of
the natural gas industry, providing essential services between the wellhead and
the end user.  These services include marketing, storage, transportation,
gathering and processing.  American Oil and Gas has 409 employees.

Petrie Parkman & Co. and Rauscher Pierce Refsnes, Inc. are serving as financial
advisors to K N Energy in connection with the merger, and Goldman, Sachs & Co.
is serving in the same capacity for American Oil and Gas.
