     (d) and (e)    No Reporting Person or Related Party has, during
the last five years, been convicted in a criminal proceeding
(excluding traffic violations or similar misdemeanors), or been a
party to a civil proceeding of a judicial or administrative body of
competent jurisdiction and as a result of such proceeding was or is

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

     LG&E Energy has the power to vote 10,395,665 of the shares of
Common Stock reported herein in certain circumstances, pursuant to a
Limited Irrevocable Proxy, dated February 10, 1995 (the "Santa Fe
Proxy") granted by Santa Fe Energy Resources, Inc. ("Santa Fe").  LG&E
Energy has the power to vote the remaining 6,312,942 shares of Common
Stock reported herein in certain circumstances, pursuant to a Limited
Irrevocable Proxy dated February 10, 1995 (the "Prudential Proxy")
granted by The Prudential Insurance Company of America, Pruco Life
Insurance Company and PruSupply, Inc. (collectively, "Prudential").
The Santa Fe Proxy and the Prudential Proxy are discussed further in
Item 4.  Copies of the Santa Fe Proxy and the Prudential Proxy are
filed as Exhibits 5 and 6, respectively, and are incorporated herein
by reference.

     LG&E Energy and Carousel have not had to pay funds, and are not
currently required to pay funds, in connection with the shares of
Common Stock reported herein.  Such funds will become due if and
immediately prior to when the Merger contemplated by the Merger
Agreement becomes effective.  The Santa Fe Securities Purchase
Agreement provides for an aggregate purchase price of $55.25 million
for all of the securities being purchased and sold thereunder (which
are listed in Item 4), including without limitation 10,395,665 shares
of Issuer's Common Stock.  The Prudential Securities Purchase
Agreement provides for an aggregate purchase price of $63 million
(plus accrued interest, if any, on the 8% Senior Secured Notes) for all of the
securities being purchased and sold thereunder (which are listed in
Item 4), including without

CUSIP No. 40501V101          13D           Page 9

limitation 1,329,762 shares of Issuer's Common Stock and the rights
and benefits in 4,983,180 shares of Issuer's Common Stock under the HP
Trust.  Moreover, if and when the Merger becomes effective pursuant to
the Merger Agreement, LG&E Energy and Carousel will be required to pay
$2.75 per share (or approximately $24.7 million in the aggregate) for
the outstanding shares of Common Stock of Issuer, excluding any shares
acquired pursuant to the Santa Fe Securities Purchase Agreement and
the Prudential Securities Purchase Agreement and certain other shares
as described in Item 4.  LG&E Energy and Carousel currently anticipate
that they would obtain such funds through one or more of working
capital, affiliates' working capital, an existing bank facility
and/or a new bank facility.  Carousel is a wholly-owned subsidiary of
Parent, which in turn is a wholly-owned subsidiary of LG&E Energy .

ITEM 4.  PURPOSE OF TRANSACTION

     The transactions reported herein have been entered into with the
purpose of obtaining ownership and control of all voting securities of
Issuer, with the effect that Issuer will become an indirect wholly-owned
subsidiary of LG&E Energy pursuant to a merger of Carousel with and
into Issuer, with Issuer as the surviving corporation (the "Merger").
Issuer, LG&E Energy and Carousel have entered into an Agreement and
Plan of Merger, dated as of February 10, 1995 (the "Merger
Agreement"), providing for the Merger, subject to the satisfaction of
certain conditions, including obtaining the consent of the requisite
holders of the Issuer's Common Stock.  A copy of the Merger Agreement
is filed as Exhibit 2.  Articles I, II, III, IV, VII, VIII, IX and X
of the Merger Agreement are incorporated herein by reference.

     If the Merger is approved and becomes effective, Carousel will be
merged with and into Issuer, with Issuer as the surviving corporation,
(i) each share of common stock of Carousel will be converted into and
become one fully-paid and nonassessable share of Common Stock of the
surviving corporation, (ii) each share of Common Stock of Issuer
issued and outstanding immediately prior to the effective time (other
than treasury shares, shares beneficially owned by LG&E Energy or its
subsidiaries, including without limitation shares of the Issuer's
Common Stock held in the HP Trust, and shares held by holders who have
properly exercised, and not withdrawn or lost, appraisal rights under
the Delaware General Corporation Law) shall be converted into and
become a right to receive $2.75 in cash, without any interest thereon,
(iii) each share of Series A Preferred shall remain unchanged and outstanding
and shall represent one share of Series A Preferred of the surviving
corporation, (iv) each share of Series B Preferred shall remain
unchanged and outstanding and shall represent one share of Series B Preferred
of the surviving corporation, (v) the directors of Carousel immediately prior
to the Merger's effectiveness will become the directors of the
surviving corporation and the executive officers of Issuer immediately
prior to the Merger's effectiveness are expected to remain as the
executive officers of the surviving corporation; (vi) the certificate
of incorporation of Issuer in effect immediately prior to the Merger
shall be the certificate of incorporation of the surviving corporation
and the bylaws of Carousel in effect immediately prior to the Merger
shall be the bylaws of the surviving corporation, in either case until
duly amended in accordance with applicable law; (vii) the Common Stock
will be delisted from the New York Stock Exchange, and (viii) the
Common Stock will become eligible for termination of registration
pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934.

     As mentioned in Item 3, LG&E Energy has the power to vote the
shares of Common Stock reported herein in certain circumstances,
pursuant to the Santa Fe Proxy and the Prudential Proxy (collectively
the "Proxies").  Specifically, the Proxies entitle LG&E Energy to vote
any shares of Common Stock held by Santa Fe and Prudential,
respectively, in such manner as to cause the Merger to be approved,
only if Santa Fe or Prudential, respectively, fails or refuses to vote
its shares of Common Stock in favor of the Merger.  Santa Fe and
Prudential granted the Proxies in accordance with the terms of two
related Securities Purchase Agreements, dated February 10, 1995 with
LG&E Energy and Carousel (the "Santa Fe Securities Purchase Agreement"
and the "Prudential Securities Purchase Agreement," respectively).

     The Santa Fe Securities Purchase Agreement provides for the sale
by Santa Fe to LG&E Energy and Carousel of (i) 10,395,665 shares of
Issuer's Common Stock, (ii) 2,335,907 shares of Senior Cumulative
Preferred Stock, Series A of Issuer (the "Series A Preferred"), and
(iii) $2.35 million in aggregate principal amount of 9% Junior Notes
of Issuer.  Such purchase and sale is to become effective immediately
prior to the Merger.  A copy of the Santa Fe Securities Purchase
Agreement is filed as Exhibit 3.  Articles 1, 2, 5, 6, 7 and 8 of the
Santa Fe Securities Purchase Agreement are incorporated herein by
reference.

     The Prudential Securities Purchase Agreement provides for the
sale by Prudential to LG&E Energy and Carousel of (i) 1,329,762 shares
of Issuer's Common Stock, (ii) the rights and benefits provided under
the Agreement and Declaration of Trust (the "HP Trust"), dated
December 14, 1993, by and among Issuer, Prudential, and Liberty Bank
and Trust Company of Oklahoma, N.A., in 4,983,180 shares of Issuer's
Common Stock, (iii) 5,010 shares of Junior Exercisable Automatically
Convertible Preferred Stock, Series B of Issuer (the "Series B
Preferred") and (iv) $56.4 million in original aggregate principal
amount of 8% Senior Secured Notes due 2003 of Issuer.  Such purchase
and sale is to become effective immediately prior to the Merger.  A
copy of the Prudential Securities Purchase Agreement is filed as
Exhibit 4.  Articles 1, 2, 5, 6, 7 and 8 of the Prudential Securities
Purchase Agreement are incorporated herein by reference.

                                  ARTICLE IV

      4.1   CONVERSION OF COMPANY STOCK.  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 Parent, Merger Sub, the Company or the holder
of any of the following securities:

            (a)   Each share of the common stock, $1.00 par value, of Merger Sub
issued and outstanding immediately prior to the Effective Time shall be
converted into and become one validly issued, fully paid and nonassessable share
of common stock, $.01 par value, of the Surviving Corporation.

            (b)   Each share of the common stock, $.01 par value, of the Company
(the "COMPANY COMMON STOCK") issued and outstanding immediately prior to the
Effective Time (other than shares of Company Common Stock to be canceled
pursuant to Section 4.1(c) hereof and shares of Company Common Stock held by any
holder who shall have properly exercised, and not withdrawn or lost, appraisal
rights under the DGCL) shall be converted into and become a right to receive
$2.75 in cash, without any interest thereon (the "PURCHASE PRICE").

            (c)   Each share of Company Common Stock issued and held in the
Company's treasury (or beneficially owned by Parent or its subsidiaries,
including, without limitation, shares of Company Common Stock held in the "HP
TRUST," as defined in, and as to which a beneficial interest is acquired by
Parent or Merger Sub pursuant to, the Securities Purchase Agreement among
Parent, Merger Sub and Prudential) at the Effective Time shall cease to be
outstanding and shall be cancelled and retired without payment of any
consideration therefor.

            (d)   Each share of Senior Cumulative Preferred Stock, Series A (the
"SERIES A PREFERRED") and Junior Exercisable Automatically Convertible
Preferred Stock, Series B (the "SERIES B PREFERRED") of the Company issued and
outstanding immediately prior to the Effective Time shall remain unchanged and
outstanding and shall represent one share of Series A Preferred or Series B
Preferred, as the case may be, of the Surviving Corporation.

      4.2   EXCHANGE OF CERTIFICATES REPRESENTING COMPANY COMMON STOCK.

            (a)   Prior to the Effective Time, Parent shall deposit, or shall
cause to be deposited, with an exchange agent selected by Parent, which shall be
Parent's Transfer Agent or such other party reasonably satisfactory to the
Company (the "EXCHANGE AGENT"), for the benefit of the holders of outstanding
shares of Company Common Stock, for payment in accordance with this Article 4, a
sum in cash equal to the product of (i) the


                                     -3-
<PAGE>

Purchase Price and (ii) the number of shares of Company Common Stock issued and
outstanding as set forth in Section 5.4 (other than shares of Company Common
Stock to be canceled pursuant to Section 4.1(c) hereof and shares of Company
Common Stock held by any holder who shall have properly exercised, and not
withdrawn or lost, appraisal rights under the DGCL), such sum being hereinafter
referred to as the "EXCHANGE FUND", to be paid pursuant to this Section 4.2 in
exchange for outstanding shares of Company Common Stock.

            (b)   Promptly after the Effective Time, Parent shall cause the
Exchange Agent to mail to each holder of record of a certificate or certificates
representing outstanding shares of Company Common Stock (other than shares of
Company Common Stock to be canceled pursuant to Section 4.1(c) hereof and shares
of Company Common Stock held by any holder who shall have properly exercised,
and not withdrawn or lost, appraisal rights under the DGCL) (i) a letter of
transmittal which shall specify that delivery of such certificates shall be
effected, and risk of loss and title to the certificates shall pass, only upon
delivery of the certificates to the Exchange Agent and shall be in such form and
have such other provisions as Parent may reasonably specify and (ii)
instructions for use in effecting the surrender of the certificates in exchange
for payment of the Purchase Price per share hereunder.  Upon surrender of a
certificate for cancellation to the Exchange Agent together with such letter of
transmittal, duly executed and completed in accordance with the instructions
thereto, the holder of such certificate shall be entitled to receive in exchange
therefor, in cash, without interest, the product of (x) the Purchase Price and
(y) the number of shares of Company Common Stock represented by such
certificates so surrendered by such holder, and the certificate so surrendered
shall forthwith be cancelled.  In the event of a transfer of ownership of
Company Common Stock which is not registered in the transfer records of the
Company, the Exchange Agent may condition payment hereunder upon the surrender
of the certificate representing such Company Common Stock to the Exchange Agent,
accompanied by all documents required to evidence and effect such transfer and
to evidence that any applicable stock transfer taxes have been paid.

            (c)   At or after the Effective Time, there shall be no transfers on
the stock transfer books of the Company of the shares of Company Common Stock
which were outstanding immediately prior to the Effective Time.  If, after the
Effective Time, certificates are presented to the Surviving Corporation, they
shall be exchanged for payment and cancelled in accordance with the procedures
set forth in this Article 4.

            (d)   Any portion of the Exchange Fund (including the proceeds of
any investments thereof) that remains unclaimed by the former stockholders of
the Company twelve (12) months after the Effective Time shall, at the option of
the Surviving  Corporation, be delivered to the Surviving Corporation.  Any
former stockholders of the Company who have not theretofore complied with this
Article 4 shall thereafter look only to the Surviving Corporation for payment of
the Purchase Price in respect of each share of Company Common Stock that such
stockholder holds as determined pursuant to this Agreement, in each case,
without any interest thereon.

            (e)   None of Parent, the Company, the Exchange Agent or any other
person shall be liable to any former holder of shares of Company Common Stock
for any amount


                                     -4-
<PAGE>

properly delivered to a public official pursuant to applicable abandoned
property, escheat or similar laws.

            (f)   If any certificate shall have been lost, stolen or destroyed,
upon the making of an affidavit of that fact by the person claiming such
certificate to be lost, stolen or destroyed and, if required by the Surviving
Corporation, the posting by such person of a bond in such reasonable amount as
the Surviving Corporation may direct as indemnity against any claim that may be
made against it with respect to such certificate, the Exchange Agent will pay in
respect of such lost, stolen or destroyed certificate an amount of cash, without
interest, equal to the product of (x) the Purchase Price and (y) the number of
shares of Company Common Stock previously represented by such lost, stolen or
destroyed certificate.

      4.3   DISSENTING SHARES.

            (a)   Notwithstanding anything in this Agreement to the contrary,
shares of Company Common Stock that are held by any record holder who has not
voted in favor of the Merger or consented thereto in writing and who has
demanded appraisal rights in accordance with Section 262 of the DGCL (the
"DISSENTING SHARES") shall not be converted into the right to receive the
Purchase Price hereunder but shall instead become the right to receive such
consideration as may be determined to be due in respect of such Dissenting
Shares pursuant to the DGCL; PROVIDED, HOWEVER, that any holder of
Dissenting Shares who shall have failed to perfect, or shall have withdrawn or
lost, his rights to appraisal of such Dissenting Shares, in each case under the
DGCL, shall forfeit the right to appraisal of such Dissenting Shares, and each
of such Dissenting Shares shall be deemed to have been converted into the right
to receive, as of the Effective Time, the Purchase Price in accordance with
Article 4, without interest.  Notwithstanding anything contained in this Section
4.3, if (i) the Merger is rescinded or abandoned or (ii) if the stockholders of
the Company revoke the authority to effect the Merger, then the right of any
stockholder to receive such consideration as may be determined to be due in
respect of such Dissenting Shares pursuant to the DGCL shall cease.  The
Surviving Corporation shall comply with all of its obligations under the DGCL
with respect to holders of Dissenting Shares.

            (b)   The Company shall give Parent (i) prompt notice of any demands
for appraisal, and any withdrawals of such demands, received by the Company and
any other related instruments served pursuant to the DGCL and received by the
Company and (ii) the opportunity to direct all negotiations and proceedings with
respect to demands for appraisal under the DGCL.  The Company shall not, except
with the prior written consent of Parent, make any payment with respect to any
demands for appraisal or offer to settle any such demands.

      4.4   COMPANY OPTIONS.  The Company shall use all reasonable efforts
to provide that, immediately prior to the Effective Time, each outstanding
option to purchase shares of Company Common Stock, each stock appreciation
right, and each limited stock appreciation right or other similar right
(individually, a "COMPANY OPTION" and collectively, the "COMPANY OPTIONS")
granted under the Hadson Corporation 1992 Equity Incentive Plan, as amended and
restated as of March 9, 1994, the Nonstatutory Stock Option Agreement


                                     -5-
<PAGE>

dated December 13, 1993, and the Nonstatutory Stock Option Agreement dated
December 14, 1993 (collectively, the "COMPANY OPTION PLANS"), whether or not
exercisable, shall be cancelled and surrendered to the Company and each holder
of each such outstanding option, outstanding stock appreciation right and
outstanding limited stock appreciation right or other outstanding similar right
shall be entitled to receive from the Company, upon surrender of the applicable
right, with respect to each such right, an amount in cash equal to the excess,
if any, of the Purchase Price over the exercise price per share of Company
Common Stock of such right.  As used herein, the term "OPTION CASH-OUT AMOUNT"
shall mean the sum of (a) all payments made by the Company to effect the
cancellation and surrender of Company Options pursuant to this Section 4.4 and
(b) the amount by which (i) the product of $2.75 multiplied by the number of
shares of Company Common Stock issued upon exercise of Company Options exercised
after the date of this Agreement and prior to the Effective Time exceeds (ii)
the sum of all payments received by the Company upon the exercise of such
Company Options during such period.


                                  ARTICLE V

               REPRESENTATIONS AND WARRANTIES OF THE COMPANY

      Except as set forth in the disclosure letter delivered by or on behalf of
the Company to Parent at or prior to the execution hereof (the "COMPANY
DISCLOSURE LETTER"), the Company represents and warrants to Parent as follows:

      5.1   EXISTENCE; GOOD STANDING; CORPORATE AUTHORITY.  The Company is a
corporation duly incorporated, validly existing and in good standing under the
laws of the State of Delaware.  The Company is duly licensed or qualified to
do business as a foreign corporation and is in good standing under the laws of
each other state of the United States in which the character of the properties
owned or leased by it therein or in which the transaction of its business makes
such qualification necessary, except where the failure to be so licensed or
qualified or be in good standing would not, individually or in the aggregate, be
reasonably expected to have a material adverse effect on the business, assets,
liabilities, financial condition or prospects (the "CONDITION") of the Company
and its Subsidiaries taken as a whole (a "MATERIAL ADVERSE EFFECT").  The
Company has all requisite corporate power and authority to own, operate and
lease its properties and carry on its business as now conducted.  The copies of
the Company's Restated Certificate of Incorporation, dated December 14, 1993, as
amended by the Certificate of Amendment to Restated Certificate of
Incorporation, dated November 21, 1994, and By-laws, dated December 14, 1993,
previously delivered to Parent are true and correct.

      5.2   COMPLIANCE WITH LAW.  Neither the Company nor any of its
Subsidiaries is in violation of any order of any court, governmental authority
or arbitration board or tribunal, or any law, ordinance, governmental rule or
regulation to which the Company or any of its Subsidiaries or any of their
respective properties or assets is subject, except where such violation would
not, individually or in the aggregate, have a Material Adverse Effect.  The
Company and its Subsidiaries (a) have made all required filings, applications,
notifications and reports, and amendments thereto, with all federal, state,
local or foreign governmental


                                     -6-
<PAGE>

authorities (the "FILINGS") and (b) possess all licenses, permits, ordinances,
franchises, certificates, and other authorizations of any federal, state, local
or foreign governmental authority (the "LICENSES") which are necessary to the
ownership or operation of their business as currently conducted or to collect
the current fees, prices, rates or other charges levied in connection with their
business and all such Filings and Licenses are in full force and effect and no
proceeding is pending or, to the Company's knowledge, threatened seeking the
revocation or limitation of any such Filing or License, except where the failure
to make any Filing or possess any License or the failure of any such Filing or
License to be in such force and effect or the revocation or limitation of such
Filing or License would not, individually or in the aggregate, have a Material
Adverse Effect.

      5.3   AUTHORIZATION, VALIDITY AND EFFECT OF AGREEMENTS.

            (a)   The Company has the requisite corporate power and authority to
execute and deliver this Agreement and all agreements and documents contemplated
hereby.  Upon receipt of the approval of this Agreement and the transactions
contemplated hereby by the holders of a majority of the outstanding shares of
Company Common Stock, the consummation by the Company of the transactions
contemplated hereby will have been duly authorized by all requisite corporate
action.  This Agreement constitutes the valid and legally binding obligation of
the Company, enforceable against the Company in accordance with its terms,
subject to applicable bankruptcy, insolvency, moratorium or other similar laws
relating to creditors' rights and general principles of equity.

            (b)   The Board of Directors of the Company has taken all necessary
action to approve the transactions contemplated by this Agreement and the
Securities Purchase Agreements pursuant to Section 203(a) of the DGCL.

      5.4   CAPITALIZATION.  The authorized capital stock of the Company
consists of 50,000,000 shares of Company Common Stock, and 25,000,000 shares of
preferred stock, par value $.01 per share (the "COMPANY PREFERRED STOCK"),
5,193,250 shares of which have been designated Series A Preferred and 4,983,180
shares of which have been designated Series B Preferred.  As of the date hereof,
there are 25,690,890 shares of Company Common Stock issued and outstanding,
2,271,496 shares of Series A Preferred issued and outstanding and 4,981,743
shares of Series B Preferred issued and outstanding.  No additional shares of
capital stock of the Company have been issued or will be issued prior to the
Effective Time except such shares of Company Common Stock as may be issued upon
exercise of Company Options or shares of Series B Preferred outstanding as of
the date hereof.  All such issued and outstanding shares of Company Common Stock
and Company Preferred Stock are duly authorized, validly issued, fully paid,
nonassessable and free of preemptive rights.  Other than as contemplated by this
Agreement, the Company Option Plans or the Series B Preferred, there are not at
the date of this Agreement any existing options, warrants, calls, subscriptions,
convertible securities, or other rights, agreements or commitments which
obligate the Company or any of its Subsidiaries to issue, transfer or sell any
shares of capital stock of the Company or any of its Subsidiaries.  As of the
date of this Agreement, there are reserved for issuance, and issuable upon or
otherwise deliverable in connection with the exercise of outstanding Company
Options, the number of shares of Company Common Stock set forth in the Company
Disclosure Letter; since that date, no Company Options


                                     -7-
<PAGE>

have been granted under the Company Option Plans and no new option plans have
been authorized or adopted and no options have otherwise been granted.  After
the Effective Time, the Surviving Corporation will have no obligation to issue,
transfer or sell any shares of capital stock of the Company or the Surviving
Corporation pursuant to any Company Benefit Plan (as defined in Section 5.12)
except pursuant to such Company Options, if any, as shall not be cancelled and
terminated prior to the Closing.  Except for the Company's obligations under the
Trust Agreement dated as of December 14, 1993 among the Company, Prudential and
certain other parties (the "H/P TRUST AGREEMENT"), there are no outstanding
obligations of the Company or any of its Subsidiaries to purchase, redeem or
otherwise acquire any shares of Company Common Stock, any capital voting
securities or securities convertible into or exchangeable for capital stock or
voting securities of the Company.  The Exercise Price (as such term is used in
the Company's Restated Certificate of Incorporation, dated December 14, 1993, as
amended through the date of this Agreement) of the Series B Preferred is $3.225
per share of Company Common Stock.

      5.5   SUBSIDIARIES.  Each of the Company's subsidiaries (each a
"SUBSIDIARY," and collectively the "SUBSIDIARIES") is a corporation or
partnership duly organized, validly existing and in good standing under the laws
of its jurisdiction of incorporation or organization, has the corporate or
partnership power and authority to own its properties and to carry on its
business as it is now being conducted, is duly licensed or qualified to do
business and is in good standing in each jurisdiction in which the ownership of
its property or the conduct of its business requires such qualification, except
for jurisdictions in which failure to be so licensed or qualified or to be in
good standing, individually or in the aggregate, would not have a Material
Adverse Effect.  Each of the outstanding shares of capital stock of each of the
Subsidiaries is duly authorized, validly issued, fully paid and nonassessable,
was not issued in violation of any preemptive rights and is owned, directly or
indirectly, by the Company free and clear of all liens, pledges, security
interests, claims or other encumbrances.  The following information for each
Subsidiary has been previously provided to Parent, if applicable:  (a) its name
and jurisdiction of incorporation or organization; (b)its authorized capital
stock or other ownership interests; and (c) the number of issued and outstanding
shares of capital stock or other ownership interests owned of record or
beneficially by the Company.

      5.6   RELATED PARTY TRANSACTIONS.  There are no contracts,
arrangements or transactions currently in effect between the Company or any of
its Subsidiaries, on the one hand, and Santa Fe, Prudential, or any officer,
director or 5% stockholder of the Company, or any affiliate of the foregoing
persons, on the other hand, except as set forth in the Company Reports (as
defined in Section 5.9).

      5.7   OTHER INTERESTS.  Except for interests in the Subsidiaries,
neither the Company nor any Subsidiary owns directly or indirectly any interest
or investment in any corporation, partnership, joint venture, business, trust or
entity.

      5.8   NO VIOLATION.  Neither the execution and delivery by the Company
of this Agreement nor the consummation by the Company of the transactions
contemplated hereby in accordance with the terms hereof will:  (a) result in a
breach of any provisions of the certificate of incorporation or By-laws (or
similar governing documents) of the Company


                                     -8-
<PAGE>

or any Subsidiary; (b) result in a breach or violation of, a default under, or
the triggering of any payment or other material obligations pursuant to, or
accelerate vesting under, any of its existing Company Stock Option Plans, or any
grant or award made under any of the foregoing by reason of, in whole or in
part, the consummation of the Merger; (c) violate or result in a breach of any
provision of, or constitute a default (or an event which, with notice or lapse
of time or both, would constitute a default) under, or result in the termination

required by, or give rise to any payments or compensation under, or result in
the creation of any lien, security interest, charge or encumbrance upon any of
the properties of the Company or its Subsidiaries under, or result in being
declared void, voidable, or without further binding effect, any of the terms,
conditions or provisions of any note, bond, mortgage, indenture, deed of trust
or any material license, franchise, permit, lease, contract, agreement or other
instrument, commitment or obligation to which the Company or any of its
Subsidiaries is a party, or by which the Company or any of its Subsidiaries or
any of their properties is bound or affected, except for any of the foregoing
matters which would not, individually or in the aggregate, have a Material
Adverse Effect and will not impose any liability on either Parent or Merger Sub;
or (d) violate any order, writ, injunction, decree, law, statute, rule or
regulation applicable to the Company or any of its Subsidiaries or any of their
respective properties or assets, except for violations which would not,
individually or in the aggregate, have a Material Adverse Effect or prevent or
delay consummation of the transactions contemplated hereby; (e) other than the
filings provided for in Article I and filings required under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR ACT") or the
Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT") (collectively
the "REGULATORY FILINGS"), require any consent, approval or authorization of,
or declaration, filing or registration with, any domestic governmental or
regulatory authority, or any other person or entity, the failure to obtain or
make which would, individually or in the aggregate, have a Material Adverse
Effect or prevent or delay consummation of the transactions contemplated hereby.

will be correctly and accurately completed and timely filed with the appropriate
foreign, federal, state and local authorities and disclose all taxes required to

federal, state, local and foreign income taxes has been extended only with
respect to the jurisdictions and years in the Company Disclosure Letter.  The

the date when made.

      7.3   STOCKHOLDER ACTION.  (a) If required by applicable law in order

approving the Merger and this Agreement.  The date of any such stockholders'
meeting shall be set by the Board of Directors of the Company after consultation
with, and on a date approved by, Parent, whose approval shall not be
unreasonably withheld.  Unless otherwise required by the fiduciary duty of the
Board of Directors of the Company (as determined by them in good faith after
consultation with



                                     -25-
<PAGE>

outside counsel), the Board of Directors of the Company shall (i) recommend that
the Company's stockholders vote to approve the Merger and this Agreement if
proxies are solicited by the Company with respect to such vote, (ii) cause the
Company to use its best efforts to solicit from stockholders of the Company
proxies in favor of the Merger, unless, in accordance with applicable law and
the regulations of the New York Stock Exchange, such solicitation is not
required to achieve approval of the Merger (taking into account proxies granted
by Santa Fe and Prudential pursuant to the Securities Purchase Agreements), and
(iii) take all other action in their judgment necessary and appropriate to
secure the vote of stockholders required by the DGCL to effect the Merger.  To
the extent required by the fiduciary obligations of the Board of Directors (as

Board of Directors of the Company may, at any time prior to the Effective Time,
withdraw or modify its approval or recommendation to the Company's stockholders
of the Merger and this Agreement.

            (b)   In connection with the Merger, the Company shall prepare a
proxy statement pursuant to Regulation 14A under the Exchange Act or, if
applicable law and regulations of the New York Stock Exchange do not so require,
an information statement pursuant to Regulation 14C under the Exchange Act, file
such proxy statement and/or information statement with the SEC under the
Exchange Act as promptly as practicable and use all reasonable efforts to have
such proxy statement and/or information statement cleared by the SEC.  If
requested by Parent, the Company will include in such proxy and/or information
statement a proposal (the "SERIES B PROPOSAL") to the effect that the
Surviving Corporation's Certificate of Incorporation be amended, promptly
following the later of (i) consummation of the Merger or (ii) the vote of the
Series B Preferred stockholders upon such proposal (such later date being
hereinafter referred to as the "OUTSIDE DATE"), to provide that the
Scheduled Automatic Conversion Date of the Series B Preferred be changed from
December 14, 1995 to a date specified by Parent within ten business days
following the Outside Date.  Parent, Merger Sub and the Company shall cooperate
with each other in the preparation of the proxy statement and/or information
statement, and the Company shall notify Parent of the receipt of any comments of
the SEC with respect to the proxy statement and/or information statement and of
any requests by the SEC for any amendment or supplement thereto or for
additional information and shall provide to Parent promptly copies of all
correspondence between the Company or any representative of the Company and the
SEC.  The Company shall give Parent and its counsel the opportunity to review
the proxy statement and/or information statement prior to its being filed with
the SEC and shall give Parent and its counsel the opportunity to review all
amendments and supplements to the proxy statement and/or information statement
and all responses to requests for additional information and replies to comments
prior to their being filed with, or sent to, the SEC.  Each of the Company,
Parent and Merger Sub agrees to use its reasonable best efforts, after
consultation with the other parties hereto to respond promptly to all such
comments of and requests by the SEC.  As promptly as practicable after the proxy
statement and/or information statement has been cleared by the SEC, the Company
shall mail the proxy statement and/or information statement to the stockholders
of the Company.  The Company agrees that the proxy statement and/or information
statement and each amendment or supplement thereto at the time of mailing
thereof and (if applicable) at the time of the meeting of the stockholders of
the Company, will not include any untrue statement of a material fact or omit to
state a material fact required to be stated therein


                                     -26-
<PAGE>

or necessary to make the statements therein, in light of the circumstances under
which they are made, not misleading; PROVIDED, HOWEVER, that the foregoing
shall not apply to the extent that any such untrue statement of a material fact
or omission to state a material fact was made by the Company in reliance upon
and in conformity with written information furnished to the Company by Parent or
Merger Sub specifically for use in the proxy statement and/or information
statement.  Parent and Merger Sub agree that the written information concerning
Parent and Merger Sub provided by them for inclusion in the proxy statement
and/or information statement and each amendment or supplement thereto, at the
time of mailing thereof and at the time of the meeting of stockholders of the
Company, will not include an untrue statement of a material fact or omit to
state a material fact to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading.  No amendment or supplement to the proxy statement and/or
information statement will be made by the Company without the approval of the
Parent.

      7.4   FILINGS; OTHER ACTION.

            (a)   Subject to the terms and conditions herein provided, the
Company and Parent shall:  (i) promptly make their respective filings and
thereafter make any other required submissions under the HSR Act with respect to
the Merger; (ii) use all reasonable efforts to cooperate with one another in (1)
promptly determining which filings are required to be made prior to the
Effective Time with, and which consents, approvals, permits or authorizations

will use all reasonable efforts to resolve such objections, if any, as may be
asserted with respect to the Merger under the HSR Act or other antitrust laws.
If, at any time after the Effective Time, any further action is necessary or
desirable to carry out the purpose of this Agreement, the proper officers and
directors of Parent and the Company shall take all such necessary action.

otherwise transfer any interest of the Company or any Subsidiary or affiliate

Representatives shall use reasonable efforts to avoid interfering with,
hindering or otherwise disrupting the employees of the Company in the execution
of their employment duties during any visit to, or inspection of, the Company's
facilities.  Parent agrees that any written report regarding any such

any matter, including the transactions contemplated hereby, occurring at or
prior to the Effective Time to the full extent permitted by the DGCL, the

diminish the Indemnified Parties' right of indemnification.

            (b)   Parent shall cause the Surviving Corporation to use its best
efforts to cause to be maintained in effect for six years from the later of the
Effective Time or the expiration of the current policy (such later date being

Subsidiaries with respect to all matters, including the transactions
contemplated hereby, occurring prior to or at the Effective Time; PROVIDED,

least the same coverage containing terms and conditions which are no less
advantageous to the insured officers and directors so long as no lapse in
coverage occurs as a result of such substitution; and PROVIDED FURTHER,
HOWEVER, that, effective on the third anniversary of the Effective Time (or at
any time thereafter), the Surviving Corporation may substitute for such policies
an indemnity from Parent providing coverage no less advantageous to the insured
officers and directors so long as no lapse in coverage occurs as a result of
such substitution; if such substitution of an indemnity is effected, the
Surviving Corporation will provide to each such insured officer or director so
requesting a contract from Parent evidencing such indemnity.

            (c)   This Section 7.9 shall survive the closing of the transactions
contemplated hereby, is intended to benefit the Company and each of the
Indemnified


                                     -29-

with actual knowledge of such inaccuracy and only to the extent that such
inaccuracy would reasonably be expected to have a Material Adverse Effect (in
the case of a representation or warranty of the Company) or Parent Material
Adverse Effect (in the case of a representation or warranty of Parent or Merger
Sub); otherwise, inaccuracy of a representation or warranty


                                     -34-

                                    EXHIBIT A

     The opinion of Gardner, Carton & Douglas, counsel to Parent and Merger Sub
shall be substantially to the following effects:

     1.   Each of Parent and Merger Sub is a corporation duly incorporated,
validly existing and in good standing under the laws of its jurisdiction of
incorporation.  Each of Parent and Merger Sub is duly licensed or qualified to
do business as a foreign corporation and is in good standing under the laws of
each other state of the United States in which the character of the properties
owned or leased by it therein or in which the transaction of its business makes
such qualification necessary, except where the failure to be so licensed or
qualified or be in good standing would not have a material adverse effect on the
ability of Parent or Merger Sub to perform its respective obligations under the
Merger Agreement (a "PARENT MATERIAL ADVERSE EFFECT").  Parent has all requisite
corporate power and authority to own, operate and lease its properties and carry
on its business as now conducted.  Merger Sub was incorporated on January 30,
1995, and, to such counsel's knowledge, since its incorporation Merger Sub has
not conducted any business activities except in connection with the transactions
contemplated in this Agreement.

     2.   Each of Parent and Merger Sub has the requisite corporate power and
authority to execute and deliver the Merger Agreement and all agreements and
documents contemplated thereby, and the consummation by Parent and Merger Sub of
the transactions contemplated thereby has been duly authorized by all requisite
corporate action.  The Merger Agreement constitutes, and all agreements and
documents contemplated thereby (when executed and delivered pursuant thereto for
value received) will constitute, the valid and legally binding obligations of
Parent and Merger Sub, enforceable against each of them in accordance with their
respective terms, subject to applicable bankruptcy, insolvency, moratorium or
other similar laws relating to creditors' rights and general principles of
equity.

     3.   Neither the execution and delivery by Parent and Merger Sub of the
Merger Agreement, nor the consummation by Parent and Merger Sub of the
transactions contemplated thereby in accordance with the terms thereof, will:
(1) result in a breach of any provisions of the Certificate of Incorporation or
By-laws of Parent or Merger Sub; (2) violate or result in a breach of any
provisions of, or constitute a default (or an event which, with notice or lapse
of time or both, would constitute a default) under, or result in the termination
or in a right of termination or cancellation of, or accelerate the performance
required by, or give rise to any payments or compensation under, or result in
the creation of any lien, security interest, charge or encumbrance upon any of
the properties of Parent or Merger Sub under, or result in being declared void,
voidable, or without further binding effect, any of the terms, conditions or
provisions of any note, bond, mortgage, indenture, deed of trust or any material
license, franchise, permit, lease, contract, agreement or other instrument,
commitment or obligation to which Parent or Merger Sub is a party, or by which
Parent or Merger Sub or any of their properties is bound or affected, except for
any of the foregoing matters which would not, individually or in the aggregate,
have a Parent Material Adverse Effect and will not impose any liability on the
Company; (3) violate any order, writ, injunction, decree, law, statute, rule or
regulation applicable to Parent or Merger Sub or any of their respective
property or assets of which were are aware

<PAGE>

(after consultation with Parent's General Counsel), except for violations which
would not individually or in the aggregate, have a Parent Material Adverse
Effect; or (4) based upon the representation and warranty of the Company made in
Section 5.19 and compliance by the Company with Section 7.4, require any
consent, approval or authorization of, or declaration, filing or registration
with, any domestic governmental or regulatory authority (other than the
Regulatory Filings), or any other person or entity, the failure to obtain or
make which would have, individually or in the aggregate, a Parent Material
Adverse Effect.
<PAGE>

                                    EXHIBIT B

     The opinion of Akin, Gump, Strauss, Hauner & Feld, L.L.P., special counsel
to the Company, shall be substantially to the following effects:

     1.   The Company is a corporation, duly incorporated, validly existing and
in good standing under the laws of the State of Delaware. The Company is duly
licensed or qualified to do business as a foreign corporation and is in good
standing under the laws of each other state of the United States in which the
character of the properties owned or leased by it therein or in which the
transaction of its business makes such qualification necessary [relying as to
factual matters in support thereof solely upon an Officer's Certificate of the
Company], except where the failure to be so licensed or qualified or be in good
standing would not reasonably be expected to have a Material Adverse Effect. The
Company has all requisite corporate power and authority to own, operate and
lease its properties and carry on its business as now conducted.

     2.   The Company has the requisite corporate power and authority to execute
and deliver the Merger Agreement and all agreements and documents contemplated
thereby. The Company Board Approval as well as all approvals of the stockholders
of the Company required under the DGCL, the charter and bylaws of the Company
and the Merger Agreement have been duly obtained and remain in full force and
effect and constitute all requisite corporate action on the part of the Company
necessary for the consummation by the Company of the transactions contemplated
by the Merger Agreement. The Merger Agreement constitutes the valid and legally
binding obligation of the Company. The Company Board Approval constitutes all
necessary action to approve the transactions contemplated by the Merger
Agreement and the Securities Purchase Agreements pursuant to Section 203(a) of
the DGCL.

     3.   The authorized capital stock of the Company is as set forth in Section
5.4 of the Merger Agreement.

     4.   Each of Hadson Gas Systems, Inc. ("Gas Systems"); Llano, Inc.
("Llano"); Minerals, Inc. ("Minerals"); Western Natural Gas and Transmission
Corporation ("Western"); Hadson Gas Co. ("Gas Co."); Hadson Gas Marketing Co.
("Gas Marketing") and Hadson Gas Gathering & Processing Co. ("Hadson Gas
Processing") is a corporation duly incorporated, validly existing and in good
standing under the laws of its jurisdiction of incorporation, has the corporate
power and authority to own its properties and to carry on its business as it is
now being conducted, and is duly licensed or qualified to do business as a
foreign corporation and is in good standing under the laws of each other state
of the United States in which the character of the properties owned or leased by
it therein or in which the transaction of its business makes such qualification
necessary [relying as to factual matters in support thereof solely upon an
Officer's Certificate from each of such companies], except where the failure to
be so licensed or qualified would not reasonably be expected to have a Material
Adverse Effect. To the Opinion Giver's Knowledge, all of the outstanding stock
of Gas Systems, Llano, Minerals, Western Gas Co., Gas Marketing and Hadson Gas
Processing is owned directly or indirectly by the Company free and clear of all
liens, pledges, security interests, claims or other encumbrances.

<PAGE>

     5.   Neither the execution and delivery by the Company of the Merger
Agreement nor the consummation by the Company of the Merger Agreement in
accordance with its terms:

     a.   contravenes or results in a breach of any provision of the certificate
          of incorporation or by-laws (or similar governing documents) of the
          Company;

     b.   violates, or constitutes a default under, or permits the termination
          of, any agreement, contract, lease or other commitment of the Company
          filed as an Exhibit to any Company Report filed by the Company with
          the SEC after December 31, 1993, other than as set forth in the
          Disclosure Letter or as set forth in Schedule 1 [to be attached to
          this opinion at the time of delivery].

     c.   to the Opinion Giver's Knowledge, violates any order, writ,
          injunction, decree, law, statute, rule or regulation applicable to the
          Company or any of its properties or assets, except for violations
          which would not reasonably be expected to have a Material Adverse
          Effect or to prevent or delay consummation of the transactions
          contemplated by the Merger Agreement.

     d.   other than the filings provided for in Article I of the Merger
          Agreement and filings required under the HSR Act or the Exchange Act
          (collectively the "Regulatory Filings"), require any consent, approval
          or authorization of, or declaration, filing or registration with, any
          domestic, governmental or regulatory authority, or any other person or
          entity, which has not been obtained or made except for those the
          failure to obtain or make would not reasonably be expected to have a
          Material Adverse Effect or prevent or delay consummation of the
          transactions contemplated by the Merger Agreement.

     6.   To the Opinion Giver's Knowledge, there is no litigation, proceeding
or governmental investigation pending or threatened against or relating to the
Company, any of its subsidiaries or any of their respective properties which
questions the validity of, or seeks damages in connection with, the Merger
Agreement or, except as set forth in the Disclosure Letter, which, if determined
adversely to the Company or its subsidiaries, would result in a Material Adverse
Effect on the Company.

     7.   The Company is not (a) an "investment company" or, to the Opinion
Giver's Knowledge, a company "controlled" by an "investment company" within the
meaning of the Investment Company Act of 1940, as amended, or (b) a "holding
company" or, to the Opinion Giver's Knowledge, a "subsidiary company" of a
"holding company" or an "affiliate" of a "holding company" or of a "subsidiary
company" of a "holding company" within the meaning of the Public Utility Holding
Company Act of 1935, as amended.

     8.   The statements in the definitive Proxy Statement or Information
Statement delivered to the stockholders of the Company in connection with the
Merger under the caption "Merger Agreement" [or other caption employed under
which the Merger Agreement and the transactions contemplated thereby are
summarized or described], insofar as such statements purport to summarize the
provisions of the Merger Agreement and the transactions contemplated thereby,
fairly summarize or describe such provisions of the Merger Agreement in all
material respects.

            8.6.  GOVERNING LAW; CHOICE OF FORUM.

            (a)   This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware without regard to its rules of
conflict of laws.

            (b)   Each of the parties hereto irrevocably (i) agrees that any
legal suit, action or proceeding brought by any of the parties hereto against
another arising out of or based upon this Agreement or the transaction
contemplated hereby may be instituted in any state or federal court located in
the State of Delaware, (ii) waives, to the fullest extent it may effectively do
so, any objection which it may now or hereafter have to the laying of venue of
any such proceeding and (iii) submits to the exclusive jurisdiction of such
courts in any such suit, action or proceeding.

            8.7.  COUNTERPARTS.  This Agreement may be executed by the parties
hereto in separate counterparts, each of which when so executed and delivered
shall be an original, but all such counterparts shall together constitute one
and the same instrument.  Each counterpart may consist of a number of copies of

hereto, but together all such copies are signed by all of the parties hereto.

            8.8.  HEADINGS.  Headings of the Articles and Sections of this

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

            8.11. SEVERABILITY.  Any term or provision of this Agreement which
is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction,
be ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or otherwise affecting the validity or enforceability of any of the
terms or provisions of this Agreement in any other jurisdiction.  If any
provision of this Agreement is so broad as to be unenforceable, the provision

is accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically

            8.13. PUBLICITY.  The initial press release relating to this
Agreement shall be a press release issued jointly by Buyers, Seller, Prudential

such press release or otherwise making public statements, with respect to the
transactions contemplated hereby and in making any filings with any federal or
state governmental or regulatory agency or with any national securities exchange
with respect thereto.

      IN WITNESS WHEREOF, the parties have executed this Agreement and caused
the same to be duly delivered on their behalf as of the day and year first
written above.

voting of their shares of Common Stock for the election of Company directors and
(b) under the HP Trust.  Each Seller has no interest, of record or beneficially,
in the investment securities of the Company, or any right to acquire same,
except for the Securities.  Each Seller has full corporate power and authority
to sell, assign and transfer the Securities.  Buyers will acquire good and valid
title to the Securities, free and clear of all liens, restrictions, claims,
charges and encumbrances of any nature whatsoever arising from or in respect of
any Seller, assuming Buyers are bona fide purchasers of such Securities within
the meaning of Section 8-302 of the Uniform Commercial Code of the State of
Delaware.  Each Seller, upon request, will execute any additional documents
reasonably necessary to complete the transfer of the Securities to Buyers.

            4.5.  ABSENCE OF CERTAIN AGREEMENTS.  Neither any Seller nor any
of any Seller's officers, directors or authorized representatives has entered
into any agreement, letter of intent or similar agreement (whether oral or
written) with any party other than Buyers whereby the Securities would be
transferred to such party.

            4.6.  NO BROKERS.  No Seller has entered into any contract,
arrangement or understanding with any person or firm, including without
limitation any director, officer or employee of the Company, which may result in
the obligation of Buyers or the Company to pay any success fee, finder's fee,
brokerage or agent's commission or other like payment in connection with the
negotiations leading to this Agreement or the consummation of the transactions
contemplated hereby.

      5.    COVENANTS.

            5.1.  NO DISPOSITION; NO LIEN.  Each Seller will not, between the
date hereof and the earlier of the Closing Time and the termination of this
Agreement, sell, dispose of, allow a lien to be created against or, in any other
manner, encumber any of the Securities or enter into any agreement with any
person (other than Buyers) with respect to any of the foregoing matters,
provided that the continued existence of the Voting Agreement shall not
constitute a breach or violation of this Section 5.1.

            5.2.  PAYMENTS; NO SOLICITATION.  Each Seller acknowledges that,
any payments to any Seller in respect of dividends, interest or principal on any
of the Securities (other than regularly scheduled interest payments on the 8%
Senior Secured Notes) declared, set aside or paid are included as part of the
Securities for purposes of this Agreement, and agrees to assign and deliver to
Buyers at the Closing Time the right to such payments.  Each Seller agrees that,
from and after its execution of this Agreement through the earlier to occur of
the Closing Time or termination of this Agreement, it shall not, nor shall it
permit any of its subsidiaries to, and it shall use its best efforts to cause
its officers, directors or employees, and all investment bankers, attorneys or
other advisors or representatives retained by such Seller or any of its
subsidiaries not to, except to the extent permitted by the Board of Directors of
the Company pursuant to Section 7.1 of the Merger Agreement (a) solicit or
encourage the submission of, any Acquisition Proposal (as hereinafter defined),
(b) enter into any agreement with respect to any Acquisition Proposal or (c)
participate in any discussions or negotiations regarding, or furnish to any
person any information with respect to, or take any other action to facilitate
any inquiries or the

making of any proposal that constitutes, an Acquisition Proposal.  For purposes
of this Agreement, "ACQUISITION PROPOSAL" means any proposal or offer for a
merger or other business combination involving the Company or to acquire a
material equity interest in or a substantial portion of the assets of the
Company, other than as contemplated by this Agreement.

            5.3.  PROXY.  Promptly following its execution and delivery of
this Agreement, each Seller will grant to Parent a proxy in the form attached
hereto as Exhibit B entitling Parent to vote all shares of Common Stock owned by
such Seller on the proposal to approve the Merger Agreement and the merger
contemplated thereby (the "MERGER") at the meeting of the Company's
stockholders called to vote on such proposal or any adjournment thereof,
provided that any such proxy shall be exercisable by the Buyers only if the
Seller granting such proxy fails or refuses to vote such shares for such
proposal at such stockholders' meeting or any adjournment thereof.  Such proxies
shall automatically terminate upon termination of this Agreement but shall
otherwise be irrevocable.

            5.4.  AMENDMENT OF HP TRUST.  Promptly following the execution and
delivery of this Agreement, each Seller will use its best efforts to cause the
amendment of Section 13.01 of the HP Trust to remove the restriction on transfer
of the Beneficial Interest.

            5.5.  PURCHASE FROM SANTA FE; CONSUMMATION OF THE MERGER.
Concurrently with the purchase of the Securities at the Closing Time, the Buyers
will purchase the securities to be purchased pursuant to the Santa Fe Securities
Purchase Agreement subject to the terms and conditions thereof.  The Buyers
agree to consummate the Merger immediately after the Closing Time subject to the
terms and conditions of the Merger Agreement.

            5.6.  NO AMENDMENT.  Without the express prior written consent of
the Sellers, the Buyers agree not to amend or modify the Merger Agreement or the
Santa Fe Securities Purchase Agreement in any respect.

            5.7.  SELLER'S AGREEMENT REGARDING EXPENSES OF THE MERGER.  To the
extent set forth in Section 7.8 of the Merger Agreement, Sellers agree to pay
the expenses incurred by the Company in connection with consummating the
transactions contemplated by the Merger Agreement.  In addition, Sellers agree
to pay the fees and expenses of Sellers' counsel relating to the negotiation of
this Agreement and the Merger Agreement and the consummation of the transactions
contemplated hereby and thereby and to forego any right they may have to seek
reimbursement from the Company for such fees and expenses.

            5.8.  AGREEMENT NOT TO WAIVE SECTION 8.1(E) OF THE MERGER
AGREEMENT.  Without the prior written consent of Sellers, Buyers agree not to
waive the condition to closing of the Merger set forth in Section 8.1(e) of the
Merger Agreement.

            5.9.  SELLERS' AGREEMENT TO ASSIST WITH THE SETTLEMENT.  Sellers
agree to use reasonable efforts to assist the Company and Buyers in their
efforts to settle the pending lawsuit referred to in Section 7.11 of the Merger
Agreement, it being understood that


                                         6

whether or not such subsidiaries or affiliates exist at the date hereof;
PROVIDED FURTHER, that no such assignment shall relieve Parent of any of its

be binding upon and shall inure to the benefit of the parties hereto and their
respective successors and assigns.  Notwithstanding anything contained in this
Agreement to the contrary, nothing in this Agreement, expressed or implied, is
intended to confer on any person other than the parties hereto or their
respective heirs, successors, executors, administrators and assigns any rights,
remedies, obligations or liabilities under or by reason of this Agreement.

            8.4.  ENTIRE AGREEMENT.  This Agreement, between the Buyers and
the Sellers, constitutes the entire agreement among the parties with respect to
the subject matter hereof and supersedes all prior agreements and understandings
(oral and written) among the parties with respect thereto.  No addition to or

hereto unless made in writing and signed by all parties hereto.

            8.5.  AMENDMENT.  This Agreement may be amended by the parties
hereto only by an instrument in writing signed by or on behalf of each of the
parties hereto.

            8.6.  GOVERNING LAW; CHOICE OF FORUM.

            (a)   This Agreement shall be governed by and construed in

legal suit, action or proceeding brought by any of the parties hereto against
another arising out of or based upon this Agreement or the transaction

courts in any such suit, action or proceeding.

            8.7.  COUNTERPARTS.  This Agreement may be executed by the parties

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

            8.11. SEVERABILITY.  Any term or provision of this Agreement which
is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction,
be ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or otherwise affecting the validity or enforceability of any of the
terms or provisions of this Agreement in any other jurisdiction.  If any
provision of this Agreement is so broad as to be unenforceable, the provision
shall be interpreted to be only so broad as is enforceable.

            8.12. ENFORCEMENT OF AGREEMENT.  The parties hereto agree that
irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed in accordance with its specific terms or was
otherwise breached.  It is accordingly agreed that the parties shall be entitled
to an injunction or injunctions to prevent breaches of this Agreement and to
enforce specifically the terms and provisions hereof, this being in addition to
any other remedy to which they may be entitled at law or in equity.

Company shall, subject to their respective legal obligations (including

making any filings with any federal or state governmental or regulatory agency
or with any national securities exchange with respect thereto.

Agreement dated as of December 14, 1993 entered into among the Sellers and the
Company.

                         LIMITED IRREVOCABLE PROXY


      THIS LIMITED IRREVOCABLE PROXY (this "PROXY"), dated February 10, 1995
is entered into among SANTA FE ENERGY RESOURCES, INC., a Delaware corporation
("SANTA FE"), and LG&E ENERGY CORP., INC., a Kentucky corporation ("LG&E").

      WHEREAS, LG&E, Carousel Acquisition Corporation, a Delaware corporation
and wholly owned subsidiary of LG&E ("CAROUSEL"), and Hadson Corporation, a
Delaware corporation ("HADSON"), have entered into an Agreement and Plan of
Merger of even date herewith to effect a merger of Carousel with and into Hadson
(the "MERGER");

      NOW, THEREFORE, Santa Fe hereby irrevocably designates LG&E, for and on
behalf of Santa Fe and in its name, place and stead, as Santa Fe's true and
lawful proxy and attorney-in-fact to attend any annual or special meeting of the
stockholders (the "STOCKHOLDERS") of Hadson at which the Merger will be voted
on by the Stockholders and to vote, or act by written consent in lieu of a vote
or meeting, any and all shares of common stock, par value $.01 per share, of
Hadson ("COMMON STOCK") that Santa Fe may own, or otherwise have the power to
vote or to direct the vote, during the term of this Proxy in such manner as to
cause the Merger to be approved; provided, however, that the foregoing
designation by Santa Fe of LG&E as Santa Fe's attorney-in-fact and proxy is
solely for the limited purpose of permitting LG&E to vote, or to act by written
consent in lieu of a vote or meeting, such shares of Common Stock in favor of
the Merger and may be exercised or otherwise utilized by LG&E only if Santa Fe
fails or refuses to vote its shares of Common Stock in favor of the Merger at
such meeting, or to act by written consent in favor of the Merger in lieu of a
meeting or vote.

      The term of this Proxy shall commence on the date hereof and shall end on
June 30, 1995, or such later date, not beyond December 31, 1995, to which any
vote on the Merger or an Amendment may be extended; provided, however, that this
Proxy shall terminate automatically upon any termination of the Securities
Purchase Agreement among Santa Fe, LG&E and Carousel.

      IN WITNESS WHEREOF, the parties have executed this Proxy and caused the
same to be duly delivered on their behalf as of the date first written above.

                         LIMITED IRREVOCABLE PROXY

      WHEREAS, LG&E, Carousel Acquisition Corporation, a Delaware corporation

      NOW, THEREFORE, Prudential hereby irrevocably designates LG&E, for and
on behalf of Prudential and in its name, place and stead, as Prudential's true
and lawful proxy and attorney-in-fact to attend any annual or special meeting of
the stockholders (the "STOCKHOLDERS") of Hadson at which the Merger or an
Amendment (as defined below) will be voted on by the Stockholders and to vote,
or act by written consent in lieu of a vote or meeting, (i) any and all shares
of common stock, par value $.01 per share, of Hadson ("COMMON STOCK") that
Prudential may own, or otherwise have the power to vote or to direct the vote,
during the term of this Proxy in such manner as to cause the Merger to be
approved, and (ii) to vote, or act by written consent in lieu of a vote or
meeting, any and all shares of Junior Exercisable Automatically Convertible
Preferred Stock, Series B of Hadson ("JUNIOR PREFERRED") that Prudential may
own during the term of this Proxy in such manner as to approve any proposed
amendment (an "AMENDMENT") that would increase or decrease the aggregate
number of shares of Junior Preferred, increase or decrease the par value of the
shares of Junior Preferred, or alter or change the powers, preferences, or
special rights of the shares of Junior Preferred so as to affect them adversely;
provided, however, that the foregoing designation by Prudential of LG&E as

limited purposes of permitting LG&E to vote, or to act by written consent in
lieu of a vote or meeting, (i) such shares of Common Stock in favor of the
Merger and (ii) such shares of Junior Preferred in favor of any proposed
Amendment, and the Designation may be exercised or otherwise utilized by LG&E

Junior Preferred in favor of the Merger and an Amendment, if any, respectively,
at such meeting, or to act by written consent in favor of the Merger and an
Amendment, if any, in lieu of a meeting or vote.

      The term of this Proxy shall commence on the date hereof and shall end on
June 30, 1995, or such later date, not beyond December 31, 1995, to which any
