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



Item 1.  Security and Issuer.
- -------  --------------------

     The class of securities to which this statement relates is the common
stock, $5.00 par value (the "Common Stock"), of K N Energy, Inc., a Kansas
corporation ("K N").  The address of the principal executive offices of K N is
370 Van Gordon Street, Lakewood, Colorado 80228-8304.

Item 2.  Identity and Background.
- -------  ------------------------

     This statement is being filed by Cabot Corporation, a Delaware
corporation (the "Reporting Person").  The Reporting Person has two principal
businesses:  (i) specialty chemicals and materials and (ii) energy.  The
Reporting Person's principal business and office address is 75 State Street,
Boston, Massachusetts 02109-1806.

     Attached hereto as Appendix A is a list of the executive officers and
directors of the Reporting Person containing the information required by
clauses (a) through (c) and (f) of Item 2 of Schedule 13D.

     During the past five years, neither the Reporting Person nor, to the
best knowledge of the Reporting Person, any person named in Appendix A hereto
has been convicted in a criminal proceeding (excluding traffic violations or
similar misdemeanors) or has been a party to a civil proceeding of a judicial
or administrative body of competent jurisdiction and as a result of which such
person was or is subject to a judgment, decree or final order enjoining future
violations of, or prohibiting or mandating activities subject to, federal or
state securities laws, or finding any violation with respect to such laws.

Item 3.  Source and Amount of Funds or Other Consideration.
- -------  --------------------------------------------------

     The securities to which this statement relates were acquired in
connection with the merger (the "Merger") of American Oil and Gas Corporation
("American") into KNE Acquisition Corporation, a wholly-owned Delaware
subsidiary of K N, on July 13, 1994.  As a result of the Merger, the Reporting
Person will receive  .47 shares of the Common Stock for each of the 8,931,818
shares of common stock of American owned by the Reporting Person prior to the
Merger.  In connection with the Merger, K N assumed warrants previously issued
by American to the Reporting Person to acquire 1,366,452 shares of the common
stock of American (the "AOG Warrants").  Under the AOG Warrants as assumed by 
K N (the "K N Warrants"), the Reporting Person is entitled to acquire the same
number of shares of Common Stock

   4

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


as it would have received had the AOG Warrants been exercised immediately prior
to the Merger--that is .47 shares of Common Stock for each share of American
common stock.  In the event the Reporting Person were to exercise the K N
Warrants, it could purchase 642,232 shares of Common Stock for a per share
exercise price of $17.55.  Such number of shares and exercise price are subject
to customary adjustments in the case of certain stock issuances,
recapitalizations and other transactions.

Item 4.  Purpose of Transaction.
- -------  -----------------------

     The securities to which this statement relates were acquired in
connection with the Merger referred to in Item 3 above.  The Reporting Person
is holding the securities of K N to which this statement relates as an
investment.  The Reporting Person has no present plans or proposals to acquire
additional securities of K N, other than such as may be acquired upon possible
exercise of the K N Warrants. The Reporting Person may dispose of securities of
K N from time to time depending on market conditions and other factors
including without limitation in order to avoid regulation as a public utility
holding company.

     The Reporting Person has filed an application (the "Application")
under Section 2(a)(7) of the Public Utility Holding Company Act ("PUHCA") with
the Securities and Exchange Commission ("SEC") seeking an exemption under the
PUHCA.  In connection with the Application, the Reporting Person has proposed
that, as a condition to receiving the exemption and so long as it owns directly
or indirectly 10% or more of the voting securities of K N, it would: (a) have
one (but not more than one) designee serve as an advisory director of K N, who
shall not vote on any matter submitted to the Board of Directors of K N (the
"Board of Directors") and shall not be the chairperson of the Board of
Directors or of any committee thereof; (b) be entitled to vote in its sole
discretion the shares of Common Stock it owned up to 9.99% of the number of K N
voting shares outstanding and, with respect to any additional shares of Common
Stock it owned (the "Excess Shares"), either not vote such Excess Shares or
vote them in the same proportions as other stockholders voted their K N shares
(notwithstanding the foregoing, the Reporting Person would be free to oppose
any action as to which dissenting shareholders would be entitled to appraisal
rights under applicable law and the Reporting Person would be free to vote its
shares of K N against the approval of such action or otherwise take any action
required to perfect appraisal rights under applicable law); (c) not enter into
any transaction with K N or any of its affiliates without the consent of the
staff of the SEC ("Staff") except: (i) to settle existing liability sharing 
obligations and environmental claims; (ii) to exercise

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


the K N Warrants; (iii) to be reimbursed for expenses incurred in connection
with attendance at meetings of K N's Board of Directors in accordance with 
K N's general policies; and (iv) the registration of the Reporting Person's
shares in K N under federal and state securities laws; (d) not solicit proxies
with respect to any of K N's voting securities without the consent of the
Staff; and (e) not acquire any additional shares of Common Stock or other
securities of K N without the consent of the Staff except (i) shares of Common
Stock acquired pursuant to stock dividends or splits that do not result in any
increase in the Reporting Person's ownership of Common Stock in excess of 1% or
(ii) shares of Common Stock acquired upon exercise of K N Warrants.  Subject to
compliance with the Securities Act of 1933, as amended (the "Act"), the
conditions proposed in the Reporting Person's Application would not limit the
Reporting Person's ability to sell its shares of Common Stock without
restriction except a sale to an affiliate of the Reporting Person, which could
only be made after giving the Staff 10 days advance notice and after the Staff
had indicated it had no objection to the sale.

      Pursuant to the merger agreement between AOG and K N, the By-laws of K N
were amended to provide that for so long as the Reporting Person continues to
own beneficially at least 10% of K N's voting securities, the Reporting Person
will have the right to designate one advisory director.  If the Reporting
Person's beneficial ownership in K N is reduced below 10% but continues over
5%, then the Board of Directors of K N will appoint the Reporting Person's
advisory director as a full director with voting rights, and the Reporting
Person will be entitled to have one designee for election to the Board of
Directors of K N.  At the time of the Merger, K N elected a designee of the
Reporting Person, John G.L. Cabot, as a non-voting advisory director of K N.

      Except as set forth herein, the Reporting Person has no present plans
or proposals that would result in or relate to any of the transactions
described in subparagraphs (a) through (j) of Item 4 to Schedule 13D.

Item 5.  Interest in Securities of the Issuer.
- -------  -------------------------------------

      As a result of the Merger, the Reporting Person owns beneficially
(within the meaning of Rule 13d-3 of the Securities Exchange Act of 1934
4,840,186 shares of Common Stock (currently issued and issuable upon exercise
of the K N Warrants).  The 4,840,186 shares of Common Stock beneficially owned
amount to approximately 17.2% of the class of Common Stock, based upon
27,580,758 shares of Common Stock being outstanding on July 14, 1994, and
642,232 shares of Common Stock issuable upon exercise of the K N Warrants.
Without taking into account any unexercised K N Warrants, the Reporting Person
currently owns 4,197,954 shares

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

of Common Stock which represents approximately 15.2% of the class of Common
Stock, based upon 27,580,758 shares of Common Stock being outstanding on July
14, 1994.  The Reporting Person possesses sole voting and dispositive power
with respect to the K N securities described in this paragraph, subject to the
limitations described in Item 4 with respect to the voting of shares in excess
of 9.99% of the voting shares of K N from time to time outstanding.

      To the best knowledge of the Reporting Person, none of the persons
listed in Appendix A hereto beneficially owned any Common Stock immediately
after the Merger except for the following:

               Director                        No. of Shares Held
               --------                        ------------------
               Samuel W. Bodman                     73,856 
               Robert P. Henderson                     446 
               Morris Tanenbaum                      2,350

Each of the persons named above had sole voting and dispositive power with
respect to such shares except for 7,385 shares held by Mr. Bodman as to which
he shared voting and dispositive power.

      To the best knowledge of the Reporting Person, none of the persons 
listed in Appendix A hereto effected any transactions of Common Stock 
of K N during the 60-day period prior to the Merger.

Item 6.  Contracts, Arrangements, Understandings or Relationships
- -------  --------------------------------------------------------
         with Respect to Securities of the Issuer.
         -----------------------------------------

      K N, American and the Reporting Person entered into an agreement 
dated June 27, 1994 (the "Claims Agreement") under which they agreed to 
extend the date previously agreed upon by American and the Reporting Person
for settling a liability sharing agreement until the later of (i) such time as
the Reporting Person owns less than 10% of K N's voting stock, (ii) such time
as the SEC has entered into an order which exempts the Reporting Person from
being treated as a public utility holding company under the PUHCA and expressly
permits the Reporting Person to take actions it deems appropriate to resolve
any claims the Reporting Person has against American or K N and any claims
American and K N may have against the Reporting Person or (iii) June 30, 1995.
K N and American also agreed in the Claims Agreement not to commence
proceedings against the Reporting Person with respect to any matter until such
time as either of the conditions referred to in clauses (i) and (ii) above are
met.  Various other issues concerning the applicability of the statute of
limitations to claims between the

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


parties and remedies for failure to comply with the provisions of the Claims
Agreement are also dealt with in the Claims Agreement.

      Pursuant to the merger agreement between AOG and K N, the Reporting 
Person entered into a Registration Rights Agreement with K N on July 13, 
1994, under which K N agreed at any time during a period of five years
following the consummation of the Merger to use its diligent best efforts to
register under the Act shares of Common Stock received as a result of the
Merger by the Reporting Person and other AOG stockholders receiving similar
registration rights agreements and shares held by affiliates of K N owning not
less than 1% of the then outstanding shares of Common Stock ("Registrable
Common Stock"), if the request to register relates to at least 750,000 shares
of Registrable Common Stock.  The obligation to effect such registration is
subject to certain conditions and limitations set forth in said Agreement.  
K N also agreed in said Registration Rights Agreement to notify holders of
Registrable Common Stock ("Holders") in the event K N determines to register
any shares of Common Stock for its own account or under various other
circumstances during said five year period and to include in such registration
Registrable Common Stock of which K N was advised by such Holder or Holders
subject only to certain conditions and limitations set forth in said Agreement.

      Pursuant to the merger agreement between AOG and K N, the Reporting 
Person and certain of its affiliates including the Reporting Person's Chairman 
and President (individually and as a trustee of a family trust) entered into 
Share Transfer and Registration Agreements with K N (the "Transfer Agreements").
The Reporting Person and such affiliates agreed in the Transfer Agreements not
to contract to sell, sell or otherwise transfer or dispose of any of the 
Common Stock or interests therein prior to the date that K N first publishes 
financial statements which reflect at least 30 days of combined operations of 
K N and American.  Notwithstanding the foregoing, the Reporting Person or such 
affiliates could contract to sell, sell or otherwise transfer or dispose of up
to 1,500,000 shares of Common Stock received through the Merger ("Subject 
Stock") at anytime after the 60th day preceding a scheduled hearing, if set by 
the SEC for the purpose of determining whether or not the Reporting Person or 
such affiliates will be deemed to be a "public utility holding company" of K N
under the PUHCA.  K N agreed in the Transfer Agreements to prepare and file 
with the SEC a continuous registration statement to enable the Reporting 
Person or such affiliates to sell from time to time up to the number of shares 
of Subject Stock in one or more transactions on the New York Stock Exchange or 
as otherwise indicated in the Transfer Agreements.  K N agreed to keep the 
registration statement effective until the Reporting Person or such affiliate 
does not own

shares of Common Stock aggregating 10% of the then outstanding shares of Common
Stock.

      In connection with the Merger, K N also entered into two agreements 
(the "Assumption Agreements") with the Reporting Person under which K N 
agreed to assume the AOG Warrants and to register shares of Common Stock
purchased by the Reporting Person upon exercise of such warrants in the manner
specified therein.  See Item 3 above.

      The foregoing descriptions of provisions of the Claims Agreement, 
the Registration Rights Agreement, the Transfer Agreements and the Assumption 
Agreements do not purport to be complete and are qualified by reference

                                                              Exhibit 1
                                                              ---------

                                   AGREEMENT

                                 June 27, 1994

         K N Energy, Inc. ("KN"), American Oil and Gas Corporation ("AOG") and
Cabot Corporation ("Cabot"), in connection with the proposed merger of AOG with
a subsidiary of KN (the "Merger"), hereby agree as follows:

         1.  AOG and/or its subsidiaries have asserted certain claims against
Cabot and/or its subsidiaries under a Stock Purchase Agreement dated June 30,
1989 among Cabot Transmission Corporation ("CTC"), Cabot and The Maple Gas
Corporation (the "Maple Claims") and under the Amended and Restated Omnibus
Acquisition Agreement dated November 13, 1989 among AOG, Cabot and CTC, as
amended.  In addition, a final settlement has not yet been reached between AOG
and Cabot pursuant to the Amended and Restated Basket Agreement dated as of
June 30, 1990 among AOG, American Pipeline Company, Cabot and CTC, as amended
(the "Basket Agreement"); and it is hereby agreed that (i) the Initial
Settlement Date provided for in the Basket Agreement shall be extended until
the later of June 30, 1995 or one of the conditions (a) or (b) set forth in
Section 2 hereof shall have occurred and (ii) the condition that the Basket
Agreement be terminated prior to consummation of the Merger is hereby waived.

         2.   KN and AOG agree that following the Merger, neither KN nor AOG
will commence any proceedings (litigation, arbitration or other) against Cabot
with respect to any matter, and that Cabot need not respond to or discuss any
claims asserted by KN or AOG in correspondence or otherwise (and that Cabot's
not responding to any such assertions shall not be taken as an admission or
acquiescence by Cabot), until such time as one or both of the following
conditions are met:
 
               (a)  Cabot owns less than 10% of KN's voting stock; or

               (b)  the Securities and Exchange Commission has entered an order
         which exempts Cabot from being treated as a public utility holding
         company under the Public Utility Holding Company Act of 1935 and
         expressly permits Cabot to take any and all actions it deems
         appropriate to resolve any claims that Cabot may have against KN
         or AOG, or which may be asserted by them against Cabot, including
         without limitation meetings and discussions with KN, AOG and their
         respective officers, directors or other representatives, initiating 
         or defending litigation or arbitration, participating in mediation 
         efforts, or otherwise.
   2



Provided, however, that if one or both of the foregoing conditions (a) and (b)
are met and subsequently cease to be met (i.e.  Cabot's stock ownership of KN
decreases below 10% and then increases above 10% pursuant to the exercise of
certain warrants Cabot will hold to buy KN shares, or such order is entered and
is then withdrawn or modified), KN and AOG shall not commence any further
proceedings against Cabot and shall take all steps necessary to suspend all
proceedings that may have been initiated, until such time as one or both of
such conditions (a) and (b) are again satisfied.  Further provided, that if
neither of the foregoing conditions (a) or (b) shall have occurred by August 1,
1996, then Cabot shall pay $2 million to AOG with respect to the Maple Claims,
which payment shall be without prejudice to Cabot's right to assert that it has
no liability to AOG with respect to the Maple Claims, or that any liability
Cabot may have is less than $2 million, and without prejudice to AOG's right to
assert that Cabot's liability to AOG with respect to the Maple Claims is
greater than $2 million; and upon final determination of the liability, if any,
of Cabot to AOG with respect to the Maple Claims (the proceedings for which
shall not be commenced or prosecuted except when one or both of the conditions
(a) or (b) are satisfied), Cabot shall pay to AOG, or AOG shall pay to Cabot,
the amount by which Cabot's liability to AOG with respect to the Maple Claims
is determined to be greater or less than $2 million, as the case may be.

      3.   Nothing herein shall relieve AOG and KN of any obligation to
give Cabot timely notice of any claims.

      4.   Cabot hereby agrees that with respect to any claim as to which
AOG or KN has given Cabot notice that is both timely under any applicable
agreement and within the applicable statute of limitations, but as to which AOG
or KN is unable to commence proceedings within the applicable statute of
limitations because of Section 2 of this Agreement, the applicable statute of
limitations shall be deemed extended to 60 days after AOG or KN is next
permitted under Section 2 of this Agreement to commence such proceedings.

      5.   AOG and KN hereby agree that in case any applicable statute of
limitations for a claim by Cabot against AOG or KN would expire at a time when
Cabot owns more than 10% of the outstanding voting stock of KN and there is not
in effect an order of the Securities and Exchange Commission as described in
condition (b) of Section 2, the applicable statute of limitations shall be
deemed extended to 60 days after Cabot no longer owns more than 10% of the
voting stock of KN or has obtained such an order.  AOG and KN further agree
that upon Cabot's request at any time when neither of conditions (a) and (b) of
Section 2 has been and remains satisfied, they will cooperate with Cabot to
suspend any such proceedings until such time as one or both of such conditions
(a) and (b) are satisfied.


                                    2

   3



      6.  If at any time when AOG or KN would not be permitted under Section 2 
of this Agreement to commence proceedings against Cabot a governmental unit or 
body shall conduct any investigation or  proceedings (i) relating to the 
remediation (or the recovery of costs associated with the remediation) of any 
property formerly owned by Cabot or one of its subsidiaries and subsequently 
owned by AOG or one or its subsidiaries, or (ii) as a result of substances
originating from or used at any such property, AOG and KN agree not to seek to
assert any claim against Cabot or to affirmatively assert that Cabot is
responsible for any such remediation or costs.  The foregoing agreement by KN
and AOG to defer taking any action against Cabot by reason of the matters
described in the foregoing sentence shall be without prejudice to their rights,
if any, to commence an action against Cabot for indemnification with respect to
such matters at such time as such an action would be permitted under Section 2
of this Agreement.  If KN or AOG shall breach their obligations under this
Section 6, then Cabot shall be entitled to recover from the party or parties
responsible for such breach, jointly and severally, as liquidated damages, an
amount equal to the costs incurred by Cabot in defending or paying any claim
asserted by KN or AOG, or by any governmental unit or any third party as a
result of the breach by KN or AOG, or in conducting any remediation that AOG or
KN may assert that Cabot is responsible for in breach of this Section 6.

      7.  Nothing herein shall be deemed an agreement by Cabot that AOG or KN 
is entitled to assert any Maple Claims against Cabot.

      8.  Each provision of this Agreement applicable to a party shall be 
deemed to apply to each of its subsidiaries (and such party will cause each
of its subsidiaries to comply therewith) to the extent necessary to carry out
the purpose and intent of this Agreement, which is to enable Cabot to defer all
disputes between Cabot and its subsidiaries on the one hand and KN and its
subsidiaries (including AOG following the Merger) on the other hand until one
or both of conditions (a) and (b) of Section 2 are satisfied.

      EXECUTED in one or more counterparts as a sealed instrument to be
governed by and construed in accordance with Massachusetts law as of the date
first above written.

                         REGISTRATION RIGHTS AGREEMENT
                         -----------------------------

                                  WITNESSETH:
                                  ----------

       WHEREAS, Stockholder beneficially owns shares of Common Stock of AOG;

       WHEREAS, the Company has been advised that Stockholder is an "affiliate"

       WHEREAS, due to Stockholder's status as an affiliate, Stockholder will
 be restricted under Rule 145 promulgated by the Commission from effecting
 sales and transfers of shares of KNE Common Stock received by Stockholder as a
 result of the Merger in excess of certain volumes; and

       WHEREAS, KNE desires to grant Stockholder certain rights to registration
 under the Act (hereinafter defined) so as to permit Stockholder the
 opportunity to dispose of shares of KNE Common Stock received by Stockholder

     to time.

         (b)  "Commission" shall mean the Securities and Exchange Commission
     or any other federal agency at the time administering the Act.

   2


         (c)   "Holder" shall mean any holder of outstanding Registrable Common
     Stock.

         (d)  "Initiating Holders" shall mean any Holders of shares of

     effectiveness of such registration statement.

         (f)   "Registrable Common Stock" shall mean (i) KNE Common Stock
     received as a result of the Merger by Stockholder and all other
     stockholders of AOG who have executed similar Registration Rights
     Agreements pursuant to Section 5.11 of the Merger Agreement and (ii) KNE
     Common Stock beneficially owned by any affiliate of KNE who beneficially
     owns in excess of 1% of the then outstanding shares of KNE Common Stock as

     similar to this Agreement.

         (g)  "Share Transfer Agreement" shall mean that certain Share Transfer
     and Registration Agreement dated of even date herewith by and between the
     Company and Stockholder.

         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 one or more 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


                                      -2-

   3

     written request given within 30 days after receipt of such written notice
     from the Company.

         (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.
     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


                                      -3-
   4

     registration if the underwriter so agrees and if the number of shares of
     Registrable Common Stock and other securities which would otherwise have
     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) Vinson & Elkins L.L.P. or other
     reputable counsel designated by the Company and reasonably satisfactory to
     the Initiating Holders 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

                                      -4-
   5

         attempt to qualify such securities under the applicable blue sky or
         other state securities laws); and

             (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

                                      -5-
   6

     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. 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,


                                      -6-
   7

     notification or the like) incident to any such registration, qualification
     or compliance, or based on any omission (or alleged omission) to state
     therein a 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 omission 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


                                      -7-
   8

     registration as is required to make the previously supplied written
     information 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 abandons the defense of such
     claim or litigation.  No Indemnifying Party, in the defense of any such
     claim or litigation, shall, except with the consent of each Indemnified
     Party, consent to entry of any judgment or enter into any settlement which
     does not include as an unconditional term thereof the giving by the
     claimant or plaintiff to such Indemnified Party of a release from all
     liability in respect to such claim or litigation.

         1.06 INFORMATION BY HOLDER.  The Holder or Holders of Registrable
 Common Stock included in any registration shall furnish to the Company such
 information regarding such Holder or Holders and the distribution proposed by
 such Holder or Holders as the Company may reasonably request in writing, and
 as shall be required in connection with any registration, qualification or
 compliance referred to in this Agreement.

         1.07 POSTPONEMENT OF REQUESTED REGISTRATION. If, within five days of
 the Company's receipt of a registration request from Initiating Holders, the
 Company notifies such Initiating Holders in writing that effecting the
 requested registration would materially and adversely affect a material
 transaction then under current consideration by the Company, as determined by
 the Board of Directors, and such determination is confirmed by an independent
 investment banker satisfactory to the Initiating Holders, then the Company may
 postpone its performance of its obligations hereunder for a period not to
 exceed 90 days.

         1.08 AMENDMENTS.  This Agreement may not be modified, amended, altered
 or supplemented except by way of a written agreement executed by each of



                                      -8-
   9

 the parties hereto. However, either party may waive any condition to the
 obligations of the other party hereunder.

         1.09 NOTICES. All notices, requests, demands and other communications
 required or permitted hereunder shall be in writing and shall be deemed to
 have been duly given if delivered by hand or facsimile transmission:

 such affiliate provided that (i) Stockholder shall remain liable for its
 obligations hereunder, (ii) Stockholder provides the Company with written

 exchange for Registrable Common Stock.

                   SHARE TRANSFER AND REGISTRATION AGREEMENT

        THIS SHARE TRANSFER AND REGISTRATION AGREEMENT (this "Agreement"), made
and entered into as of July 13, 1994, by and between K N Energy, Inc., a Kansas
corporation ("KNE"), and Cabot Corporation, a Delaware corporation (the
"Stockholder"),

                                  WITNESSETH:
                                  ----------

        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 24, 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:


                                   ARTICLE I
                         Representations and Warranties
                         ------------------------------

        1.01 REPRESENTATIONS OF THE STOCKHOLDER. The Stockholder represents and
warrants to KNE that:


                                      -1-
   2


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

        (b)  since June 13, 1994 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 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:





                                      -2-
   3

             "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 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-

        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;

        (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.



                                      -4-

        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 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



                                      -5-
   6

  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.

         (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



                                      -6-
   7


  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 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

      Reference is made to the Agreement of Merger dated as of March 24, 1994
 (the "Merger Agreement"), among K N Energy, Inc. ("K N"), KNE Acquisition
 Corporation and American Oil and Gas Corporation ("AOG"), providing for the
 merger ( the "Merger") of KNE Acquisition Corporation with and into AOG and
 the conversion on the effective date thereof of each outstanding share of AOG
 Common Stock into 0.47 of one share of K N Common Stock.  Capitalized terms
 not defined herein have the meanings attributed thereto in the Merger
 Agreement.


      Under the Warrant Agreement dated as of November 13, 1989, among AOG,
 Cabot Corporation ("Cabot") and Cabot Transmission Corporation ("CTC"),
 warrants to purchase shares of Common Stock of AOG (the "Warrants") are
 outstanding in your favor as set forth below:

Exercise Price Per Number of Shares of Share of AOG AOG Common Stock Common Stock ------------------- ------------------ 1,000,000 $8.25
The AOG Common Stock underlying the Warrants is also the subject of the Warrant Shares Registration Rights Agreement dated as of November 13, 1989 (the "Rights Agreement") among AOG, Cabot and CTC. Section 9 of your Warrant Agreement requires adjustment to the number and kind of shares covered by your Warrants and the exercise price thereof to reflect the number of shares of K N Common Stock that you would have received upon consummation of the Merger had your Warrants been exercised immediately prior to the Merger. As a result, K N hereby agrees that, from and after the Effective Time, your Warrants shall be exercisable for the purchase of K N Common Stock in the number of shares and at the exercise price set forth below:
Exercise Price Per Number of Shares of Share of K N K N Common Stock Common Stock ------------------- ------------------ 470,000 $17.55
2 In order to assume (i) your Warrants, and (ii) AOG's obligations under the Rights Agreement, more effectively and for other good and valuable consideration, the receipt of which is hereby acknowledged, K N hereby agrees with you that, from and after the Effective Time, K N shall be deemed to be the successor in interest to AOG under your Warrant Agreement and the Rights Agreement, the terms and provisions of your Warrant Agreement and Rights Agreement shall be binding on K N and for all purposes under the Warrant Agreement and the Rights Agreement: (i) K N shall be deemed to be the Company; (ii) Common Stock or Registrable Common Stock (as that term is defined in the Rights Agreement) shall be deemed to be K N Common Stock, $5.00 par value; and (iii) Houston, Texas and Houston time shall be deemed to be Lakewood, Colorado and Colorado time; provided, however, the reference to AOG's Stock Incentive Plan in clause (ii) of section 9(i) of your Warrant Agreement shall be deemed to include also K N's stock option plans for its employees or directors. You may exercise your rights under your Warrant Agreement and/or the Rights Agreement in the same manner and shall have the same rights under it as you had with AOG, except as otherwise provided in this letter. Upon your request, K N will issue you a new Warrant Certificate in your name reflecting the provisions of this letter. Except as set forth above, the terms and provisions of your Warrant Agreement and the Rights Agreement shall remain as they were prior to the Effective Time. The effectiveness of this agreement is conditioned upon the consummation of the Merger in accordance with the terms of the Merger Agreement, failing which this agreement shall be null and void.
