                        SENECA RESOURCES CORPORATION AND
                          HARCOR ENERGY, INC. ANNOUNCE
                         EXECUTION OF MERGER AGREEMENT


         Houston, Texas, March 31, 1998 -- Seneca Resources Corporation, the
exploration and production subsidiary of National Fuel Gas Company (NYSE:
NGF), and HarCor Energy, Inc. (NASDAQ NMS:  HARC) today jointly announced that
the two companies have signed a definitive merger agreement for the acquisition
of HarCor by Seneca for a total price of approximately $32.5 million in cash.

         Under the terms of the agreement, a subsidiary of Seneca will commence
a tender offer no later than April 6, 1998, to acquire all of the outstanding
shares of HarCor's Common Stock for $2.00 per share in cash.  Following
completion of the tender offer, the Seneca subsidiary will merge with HarCor,
pursuant to which the remaining HarCor stockholders will also receive $2.00 per
share in cash.

         Chase Mellon Shareholder Services, LLC will act as Information Agent
for the tender offer.  SBC Warburg Dillon Read Inc. served as financial advisor
to HarCor and has provided a fairness opinion in connection with the
transaction.

         HarCor is a Houston-based independent oil and gas company with
properties located primarily on the west side of the San Joaquin Basin in Kern
County, California.  The properties produce gas and high gravity oil and
provide for additional drilling and development over the next four years.

         According to James Beck, President of Seneca Resources, "The
acquisition of HarCor will establish Seneca as a significant independent
producer in California.  These reserves, combined with our activity in the Gulf
of Mexico and Appalachian Basin, provide the groundwork for our future growth."

         National Fuel Gas Company is an integrated energy company with
operations in all segments of the natural gas industry, including utility,
pipeline and storage, exploration and production, and marketing operations.
Seneca is headquartered in Houston and explores for and produces natural gas
and oil in the lower 48 States and the Gulf of Mexico.

         The tender offer and merger are subject to customary conditions,
including the tender of a majority of HarCor's shares and the occurrence of no
material adverse change in HarCor prior to the closing.  The tender offer will
be made pursuant to definitive documents to be filed with the Securities and
Exchange Commission.

                          AGREEMENT AND PLAN OF MERGER


         AGREEMENT AND PLAN OF MERGER dated as of March 31, 1998 by and among
HarCor Energy, Inc., a Delaware corporation (the "Company"), Seneca Resources
Corporation, a Pennsylvania corporation ("Parent"), and Seneca West Corp., a
Delaware corporation and wholly owned indirect subsidiary of Parent
("Purchaser").

                                    RECITALS

         WHEREAS, the respective Boards of Directors of the Company, Parent and
Purchaser have unanimously approved the acquisition of the Company by Parent,
upon the terms and subject to the conditions set forth herein;

         WHEREAS, it is intended that the acquisition be accomplished by
Purchaser commencing a cash tender offer for Shares (as defined in Section 1.1)
to be followed by a merger of Purchaser with and into the Company; and

         NOW, THEREFORE, in consideration of the foregoing and of the
respective representations, warranties, covenants and agreements set forth in
this Agreement, the parties hereto hereby agree as follows:

                                   ARTICLE I
                                   THE OFFER

1.1      The Offer.

         (a)     As promptly as practicable (but in no event later than five
business days following the public announcement of the execution hereof),
Purchaser shall commence (within the meaning of Rule 14d-2 under the Securities
Exchange Act of 1934, as amended (the "Exchange Act")), an offer to purchase
all of the Company's outstanding shares of common stock, par value $0.10 per
share (the "Shares"), at a price of $2.00 per Share, net to the seller in cash
(as such offer may be amended in accordance with the terms of this Agreement,
the "Offer"), subject to the conditions set forth in Annex A hereto.  Purchaser
will not, without the prior written consent of the Company, (i) decrease or
change the form of the consideration payable in the Offer, (ii) decrease the
number of Shares sought pursuant to the Offer, (iii) impose additional
conditions to the Offer, (iv) change the conditions to the Offer, except that
Parent in its sole discretion may waive any of the conditions to the Offer
other than the condition set forth in clause (1) of Annex A, which may not be
waived without the Company's prior written consent, or (v) make any other
change in the terms or conditions of the Offer that is adverse to the holders
of Shares.  Purchaser will, on the terms and subject to the prior satisfaction
or waiver of the conditions to the  Offer, accept for payment and pay for all
Shares validly tendered and not withdrawn pursuant to the Offer promptly after
expiration of the Offer; provided that, Purchaser may extend the Offer up to
the tenth business day after the later of (i) the initial expiration date of
the Offer and (ii) the date on which all such  conditions shall first have been
satisfied or waived.  The Company agrees that no Shares held by the Company
will be tendered to Parent pursuant to the Offer; provided, that Shares held
beneficially or of record by any
<PAGE>   6
plan, program or arrangement sponsored or maintained for the benefit of
employees of the Company shall not be deemed to be held by the Company,
regardless of whether the Company has, directly or indirectly, the power to
vote or control the disposition of such Shares.  The obligations of Purchaser
to commence the Offer and to accept for payment and to pay for Shares validly
tendered on or prior to the expiration of the Offer and not withdrawn shall be
subject only to the conditions set forth in Annex A hereto.

         (b)     On the date of commencement of the Offer, Parent and Purchaser
shall file or cause to be filed with the Securities and Exchange Commission
(the "SEC") a Tender Offer Statement on Schedule 14D-1 (together with all
amendments thereto, the "Schedule 14D-1") with respect to the Offer, which
shall contain the offer to purchase and related letter of transmittal and other
ancillary offer documents and instruments pursuant to which the Offer will be
made (collectively, together with any supplements or amendments thereto, the
"Offer Documents").  Parent and Purchaser will disseminate the Offer Documents
to holders of Shares.  Each of Parent, Purchaser and the Company will promptly
correct any information provided by it for use in the Offer Documents that
becomes false or misleading in any material respect and Parent and Purchaser
will take all steps necessary to cause the Offer Documents as so corrected to
be filed with the SEC and to be disseminated to holders of Shares, in each case
as and to the extent required by applicable law.  The Company and its counsel
shall be given a reasonable opportunity to review and comment on the Offer
Documents prior to their filing with the SEC.  Parent and Purchaser agree to
provide the Company with any comments that may be received from the SEC or its
staff with respect to the Offer Documents promptly after receipt thereof and to
further provide the Company with a reasonable opportunity to participate in all
substantive communications with the SEC and its staff relating to the Offer
Documents, the Offer or the transactions contemplated thereby.

1.2      Company Actions.  The Company hereby consents to the Offer and
represents and warrants (i) that its Board of Directors (at meetings duly
called and held) (a) has unanimously determined as of the date hereof that the
Offer and the Merger are fair to and in the best interests of the stockholders
of the Company, (b) has unanimously approved this Agreement and resolved to
recommend acceptance of the Offer and approval and adoption of this Agreement
and the Merger by the stockholders of the Company, (ii) that such approval
constitutes approval of this Agreement and the transactions contemplated hereby
for purposes of Section 203 of the DGCL and (iii) that the Board of Directors
will not withdraw, amend or modify such recommendation unless it determines in
good faith, on the advice of outside counsel, that such action is necessary for
the Board of Directors to comply with its duties to the Company's stockholders
under applicable law.  On the date of the commencement of the Offer, the
Company shall file or cause to be filed with the SEC a
Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule 14D-9")
containing the unanimous recommendation of the Board of Directors in favor of
the Offer and the Merger and shall permit the inclusion in the Schedule 14D-1
of such recommendation, in each case subject to the fiduciary duties of the
Board of Directors of the Company.  Each of the Company, Parent and Purchaser
will promptly correct any information provided by it for use in the Schedule
14D-9 that becomes false or misleading in any material respect and the Company
will take all steps necessary to cause the Schedule 14D-9 as so corrected to be
filed with the SEC and to be disseminated to holders of Shares, in each case as
and to the extent required by applicable law.  Parent and its counsel shall be
given a reasonable opportunity to review and comment on the Schedule 14D-9
prior to its filing with the SEC.  The Company agrees to provide Parent with
any comments that may be





                                      -2-
<PAGE>   7
received from the SEC or its staff with respect to the Schedule 14D-9 promptly
after receipt thereof and to further provide Parent with a reasonable
opportunity to participate in all substantive communications with the SEC and
its staff relating to the Schedule 14D-9, the Offer or the transactions
contemplated thereby.

1.3      Stockholder Lists.  In connection with the Offer, the Company shall
promptly furnish or cause to be furnished to Purchaser mailing labels and
security position listings and any available listing or computer file
containing the names and addresses of the record holders of Shares as of a
recent date and shall furnish Purchaser with such information (including,
without limitation, updated lists of stockholders, mailing labels and lists of
securities positions) reasonably available to the Company and such assistance
as Parent or its agents may reasonably request in communicating the Offer to
the record and beneficial holders of Shares.  Subject to the requirements of
applicable law and except for such steps as are necessary to disseminate the
Offer Documents and any other documents necessary to consummate the Offer and
the Merger, Parent, Purchaser and their respective affiliates will hold in
confidence such listings and other information, shall use such information only
in connection with the Offer and the Merger and, if this Agreement is
terminated, shall, and shall cause their respective agents or other
representatives to, promptly deliver to the Company all copies of all such
information (and extracts or summaries thereof) then in their possession.

1.4      Directors.  Promptly upon the purchase by Purchaser pursuant to the
Offer of such number of Shares as represents at least a majority of the
outstanding Shares and from time to time thereafter, Parent shall be entitled
to designate all members of the Board of Directors of the Company.  The current
directors of the Company have indicated to the Parent that they intend to
resign as directors of the Company as soon as reasonably practicable upon the
Purchaser purchasing at least a majority of the outstanding Shares pursuant to
the Offer, and the Company shall exercise reasonable efforts to secure the
resignations of all directors to enable such Parent designees to be so elected
or appointed.  Such designees will abstain from any action proposed to be taken
by the Company to amend or terminate this Agreement or waive any action by
Parent or Purchaser.  The Company's obligations to appoint designees to the
Board of Directors shall be subject to Section 14(f) of the Exchange Act.  At
the request of Parent, the Company shall take all action reasonably necessary
to effect any such election or appointment, including mailing to its
stockholders the information required by Section 14(f) of the Exchange Act and
Rule 14f-1 promulgated thereunder, unless such information previously has been
provided to the Company's stockholders in the Schedule 14D-9.  Parent and
Purchaser will supply to the Company, and will be solely responsible for, all
information with respect to themselves and their officers, directors and
affiliates required by such Section and Rule.

                                   ARTICLE II
                                   THE MERGER

2.1      The Merger.  Upon the terms and subject to the conditions of this
Agreement, and in accordance with the General Corporation Law of the State of
Delaware (the "DGCL"), at the Effective Time (as defined below), Purchaser
shall be merged with and into the Company (the "Merger").  As a result of the
Merger, the separate corporate existence of Purchaser shall cease and the
Company shall continue as the surviving corporation of the Merger (the
"Surviving Corporation").





                                      -3-
<PAGE>   8
2.2      Closing.  Unless this Agreement shall have been terminated pursuant to
Article VII and subject to the satisfaction or, if permissible, waiver of the
conditions set forth in Article VI, the consummation of the Merger and the
other transactions contemplated hereby (the "Closing") shall take place at the
offices of Vinson & Elkins, L.L.P., 1001 Fannin St., Houston, Texas 77002-6760
as promptly as practicable (and in any event within two business days)
following the satisfaction or, if permissible, waiver of the conditions set
forth in Article VI, unless another place, date or time is agreed to in writing
by Parent and the Company.

2.3      Effective Time.  As promptly as practicable after the Closing, the
parties hereto will cause a certificate of merger (the "Certificate of Merger")
to be executed, acknowledged and filed with the Delaware Secretary of State in
accordance with the DGCL.  The Merger shall become effective at such time as
the Certificate of Merger is filed with the Delaware Secretary of State in
accordance with the DGCL, or at such later time as may be agreed to by Parent
and the Company and specified in the Certificate of Merger in accordance with
applicable law.  The date and time when the Merger shall become effective is
referred to herein as the "Effective Time."

2.4      Effect of the Merger.  The Merger shall have the effects set forth in
the applicable provisions of the DGCL.  Without limiting the generality of the
foregoing, and subject thereto, at the Effective Time, all properties, rights,
privileges, powers and franchises of the Company and Purchaser shall vest in
the Surviving Corporation, and all debts, liabilities and duties of the Company
and Purchaser shall become the debts, liabilities and duties of the Surviving
Corporation.

2.5      Certificate of Incorporation and Bylaws.  At the Effective Time, the
Amended and Restated Certificate of Incorporation (the "Certificate of
Incorporation") and the Amended and Restated Bylaws (the "Bylaws") of the
Company, in each case as in effect immediately prior to the Effective Time,
shall be the Certificate of Incorporation and the Bylaws of the Surviving
Corporation until thereafter amended as provided by law.

2.6      Directors and Officers.  At the Effective Time, the officers and
directors of Purchaser immediately prior to the Effective Time shall become the
officers and directors of the Surviving Corporation, each to hold office from
the Effective Time until their respective successors are duly elected or
appointed and qualified in the manner provided in the Certificate of
Incorporation and Bylaws of the Surviving Corporation and applicable law.  The
Company shall use commercially reasonable efforts to cause each executive
officer and director of the Company to tender his or her resignation effective
at or before the Effective Time.

2.7      Consideration; Conversion of Shares.  At the Effective Time, by virtue
of the Merger and without any action on the part of any of the parties hereto
or the holders of any of the following securities:

         (a)     Each Share that is issued and outstanding immediately prior to
the Effective Time (other than any Shares to be canceled pursuant to Section
2.7(b) and any Dissenting Shares, as defined in Section 2.11) shall be changed
and converted into and represent the right to receive $2.00 in cash, or any
higher price paid per Share in the Offer (the "Per Share Merger
Consideration").  All such Shares shall no longer be outstanding and shall
automatically be cancelled and extinguished and shall cease to exist, and each
certificate which immediately prior to the Effective Time





                                      -4-
<PAGE>   9
evidenced any such Shares (other than Shares to be cancelled pursuant to
Section 2.7(b) and any Dissenting Shares) shall thereafter represent the right
to receive (without interest and less any applicable withholding of taxes),
upon surrender of such certificate in accordance with the provisions of Section
2.8, the Per Share Merger Consideration multiplied by the number of Shares
evidenced by such certificate (the "Merger Consideration").  The holders of
certificates previously evidencing Shares outstanding immediately prior to the
Effective Time shall cease to have any rights with respect thereto (including,
without limitation, any rights to vote or to receive dividends and
distributions in respect of such Shares), except as otherwise provided herein
or by law.

         (b)     All Shares, which immediately prior to the Effective Time are
owned by Parent, Purchaser or their respective affiliates or held by the
Company in its treasury, shall be cancelled and extinguished and shall cease to
exist and no consideration shall be delivered with respect thereto.

         (c)     Each share of capital stock of Purchaser issued and
outstanding immediately prior to the Effective Time shall be converted into and
exchanged for one validly issued, fully paid and nonassessable share of common
stock of the Surviving Corporation.

2.8      Exchange of Certificates.

         (a)     Paying Agent.  As of the Effective Time, Parent shall,
pursuant to an agreement with its paying agent (the "Paying Agent"), deposit,
or cause to be deposited, with or for the account of the Paying Agent in trust
for the benefit of the holders of Shares (other than Shares to be cancelled
pursuant to Section 2.7(b) and any Dissenting Shares) for exchange through the
Paying Agent in accordance with this Article II, cash in the aggregate amount
required to be exchanged for Shares pursuant to Section 2.7 (the "Payment
Fund").  The Paying Agent shall, pursuant to irrevocable instructions, deliver
the Merger Consideration out of the Payment Fund to holders of Shares.  The
Payment Fund shall not be used for any other purpose.  The Paying Agent shall
invest funds in the Payment Fund only in short-term securities issued or
guaranteed by the United States government or certificates of deposit of
commercial banks that have consolidated total assets of not less than
$5,000,000,000 and are "well capitalized" within the meaning of the applicable
federal bank regulations.  Any interest or other income earned on the
investment of funds in the Payment Fund shall be for the account of and payable
to the Surviving Corporation.  Parent shall replace any monies lost through any
investment made pursuant to this Section 2.8.

         (b)     Payment Procedure.  Promptly after the Effective Time, Parent
will cause the Paying Agent to mail to each holder of record of a certificate
or certificates that immediately prior to the Effective Time evidenced
outstanding Shares (other than Shares to be cancelled pursuant to Section
2.7(b) and any Dissenting Shares) ("Certificates"), (i) a notice of the
effectiveness of the Merger, (ii) a letter of transmittal (which shall specify
that delivery shall be effected, and risk of loss and title to the Certificates
shall pass, only upon proper delivery of the Certificates to the Paying Agent
and shall be in such customary form and have such other provisions as Parent
may reasonably specify in accordance with the terms of this Agreement) and
(iii) instructions to effect the surrender of the Certificates in exchange for
the Merger Consideration. Upon surrender of a Certificate for cancellation to
the Paying Agent together with such letter of transmittal, duly executed, and
such other customary documents as may be required pursuant to such
instructions, the holder of such Certificate shall be entitled to receive in
exchange therefor the Merger Consideration and the





                                      -5-
<PAGE>   10
Certificate so surrendered shall forthwith be cancelled.  In the event of a
transfer of ownership of Shares that is not registered in the transfer records
of the Company, the Merger Consideration may be paid or issued to the
transferee if the Certificate representing such Shares is presented to the
Paying Agent, accompanied by all documents required to evidence and effect such
transfer and by evidence that any applicable stock transfer taxes have been
paid.  In the event that any Certificate shall have been lost, stolen or
destroyed, the Paying Agent shall issue in exchange therefor, upon the making
of an affidavit of that fact by the holder thereof and such bond, security or
indemnity as Parent may reasonably require, the Merger Consideration that such
holder has the right to receive pursuant to the provisions of this Article II.
Until surrendered as contemplated by this Section 2.8, each Certificate shall
be deemed at any time after the Effective Time to evidence only the right to
receive upon such surrender the Merger Consideration applicable to the Shares
evidenced by such Certificate.

         (c)     Termination of Payment Fund.  Any portion of the Payment Fund
that remains undistributed to the holders of Shares for six months after the
Effective Time shall be delivered to Parent upon demand, and any holders of
Shares who have not theretofore complied with this Article II shall thereafter
look, subject to Section 2.8(d), only to Parent or the Surviving Corporation
for the Merger Consideration to which they are entitled pursuant to this
Article II.

         (d)     Abandoned Property Laws.  Neither the Surviving Corporation
nor the Paying Agent nor the Company, the Parent or any of their respective
affiliates shall be liable to any holder of a Certificate for any cash from the
Payment Fund properly delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

         (e)     Transfer Taxes.  Except as provided in paragraph (b) above,
Parent shall pay or cause to be paid any real property transfer, gains or
similar real property taxes imposed in connection with or as a result of the
Merger.

2.9      Stock Transfer Books.  At the Effective Time, the stock transfer books
of the Company shall be closed, and there shall be no further registration of
transfers of Shares thereafter on the records of the Company other than to
reflect transfers of Shares effected on or prior to the date on which and the
time at which the Effective Time occurs.  At and after the Effective Time, any
Certificates presented to the Paying Agent or the Surviving Corporation for any
reason shall be converted into the Merger Consideration applicable to the
Shares evidenced thereby.

2.10     Options and Other Purchase Rights.

         (a)     The Company represents and warrants to the Purchaser and
Parent that it has taken all action necessary so that all outstanding options
and other rights to acquire Shares granted to directors, employees or others
under any stock option or purchase plan, program or similar arrangement of the
Company (each, as amended, an "Option Plan" and, such options and other rights,
"Stock Options"), whether or not then exercisable or vested, will be cancelled
by the Company upon consummation of the Offer.  The holders thereof shall be
entitled to receive, for each Share subject to such Stock Option, in settlement
and cancellation thereof, an amount in cash equal to the positive difference,
if any, between the Per Share Merger Consideration and the exercise price per
share of such Stock Option, which amount shall be paid at the time the Stock
Option or is





                                      -6-
<PAGE>   11
cancelled; provided, that, with respect to any person subject to Section 16 of
the Exchange Act, any such amount shall be paid as soon as practicable after
the first date payment can be made without liability to such person under
Section 16(b) of the Exchange Act.  All applicable withholding taxes
attributable to the payments made hereunder or to distributions contemplated
hereby shall be deducted from the amounts payable under this Section 2.10 and
all such taxes attributable to the cancellation of Stock Options shall be
withheld from the proceeds received in connection with the cancellation
thereof.

         (b)     Except as provided herein or as otherwise agreed to by the
parties and to the extent permitted by the Option Plans, the Option Plans shall
terminate as of or prior to the Effective Time and any rights under the Stock
Options granted under the Stock Option Plans shall be cancelled as of or prior
to the Effective Time.

         (c)     The Company represents and warrants to the Purchaser and
Parent that all outstanding warrants to purchase Shares will, upon the
Effective Time, be converted into the right to receive $2.00 cash instead of
each Share which would otherwise be purchasable by the holder of the warrant
upon the exercise thereof and payment of the warrant exercise price thereunder
(which in each case is greater than $2.00 per Share).  The Company will provide
Purchaser with evidence of the foregoing or, with respect to any specific
warrant, evidence of cancellation of such warrant satisfactory to Purchaser
prior to the acceptance by Purchaser for payment of any Shares tendered under
the Offer.

2.11     Dissenting Shares.  Notwithstanding anything in this Agreement to the
contrary, Shares that are outstanding immediately prior to the Effective Time
and that are held by stockholders who shall have perfected dissenters' rights
in accordance with Section 262 of the DGCL (the "Dissenting Shares") shall not
be converted into or represent the right to receive the Merger Consideration
(but instead shall be converted into the right to receive payment from the
Surviving Corporation with respect to such Dissenting Shares in accordance with
the DGCL), unless and until such holder shall have failed to perfect or shall
have effectively withdrawn or lost such holder's rights to appraisal under the
DGCL.  If any such holder shall have failed to perfect or shall have
effectively withdrawn or lost such holder's rights to appraisal of such Shares
under the DGCL, such holder's shares shall thereupon be deemed to have been

right to receive, upon surrender as provided above, the Merger Consideration
for the Certificate or Certificates that formerly evidenced such Shares.

2.12     Company Stockholders' Meeting.  Unless the Merger is consummated in
accordance with Section 253 of the DGCL as contemplated by Section 2.13 hereof,
and subject to applicable law, the Company, acting through its Board of
Directors, shall, in accordance with the DGCL, its Certificate of Incorporation
and its Bylaws, (a) duly call, give notice of, convene and hold a special

Purchaser, respond promptly to any comments made by the Commission with respect
to the Company Proxy Statement and any preliminary version thereof and cause
the Company Proxy Statement to be mailed to its stockholders at the earliest
practicable time following the expiration or termination of the Offer and (B)
to obtain the necessary approvals by its stockholders of the Merger Agreement
and the transactions contemplated thereby.  Parent will provide the Company
with the information concerning Parent and Purchaser required to be included in
the Company Proxy Statement, and will vote, or cause to be voted, all Shares
owned by it or its affiliates in favor of approval and adoption of this
Agreement and the Merger.

2.13     Merger Without Meeting of Stockholders.  Notwithstanding anything to
the contrary in this Agreement, if Parent, Purchaser or their respective
affiliates shall acquire at least 90% of the outstanding Shares, each of
Parent, Purchaser and the Company shall take all necessary and appropriate
action to cause the Merger to become effective, as soon as practicable after
the consummation of the Offer, without a meeting of stockholders of the
Company, in accordance with Section 253 of the DGCL.

2.14     Withholding Taxes.  Except as otherwise provided in Section 2.8(e),
Parent and Purchaser shall be entitled to deduct and withhold, or cause the
Paying Agent to deduct and withhold, from the consideration otherwise payable
to a holder of Shares pursuant to the Offer or the Merger any stock transfer
taxes and such amounts as are required under the Internal Revenue Code of 1986,
as amended (the "Code"), or any applicable provision of state, local or foreign
tax law, as specified in the Offer Documents.  To the extent that amounts are
so withheld by Parent or Purchaser, such withheld amounts shall be treated for
all purposes of this Agreement as having been paid to the holder of the Shares
in respect of which such deduction and withholding was made by Parent or
Purchaser, in the circumstances described in the Offer Documents, and Parent
shall provide, or cause the Paying Agent to provide, to the holders of such
Certificates written notice of the amounts so deducted or withheld.

                         REPRESENTATIONS AND WARRANTIES
                                 OF THE COMPANY

         The Company hereby represents and warrants to Parent as follows:

3.1      Organization and Qualification.  The Company (a) is duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
incorporation, (b) has all requisite corporate power to carry on its business
as it is now being conducted, and (c) is in good standing and duly qualified to
do business in each jurisdiction in which the transaction of its business makes
such qualification necessary, except where the failure to be in good standing
or so qualified would not have a Material Adverse Effect (as defined in Section
8.3(c) below) on the Company.  True and complete copies of the Certificate of
Incorporation and the Bylaws, as amended to date, of the Company have been made
available to Parent.  The Company does not own any subsidiaries or have any
equity or partnership or joint venture interests other than as reflected on
Section 3.1 of the Company Disclosure Schedule.

3.2      Capitalization of the Company.  The authorized capital stock of the
Company consists of 25,000,000 Shares and 1,500,000 shares of preferred stock,
$0.01 par value (the "Company Preferred Stock").  As of the date hereof,
16,268,387 Shares are issued and outstanding and no shares of Company Preferred
Stock are outstanding.  All outstanding Shares are validly issued and are fully
paid and nonassessable.  Except as disclosed in the Company SEC Documents (as
defined in Section 3.6) or in Section 3.2 of the Company's disclosure schedule
delivered to Parent in connection with this Agreement (the "Company Disclosure
Schedule") there are no outstanding subscriptions, options, warrants, calls,
rights, commitments or any other agreement to which the Company is a party or
by which the Company is bound that, directly or indirectly, obligate the
Company to issue, deliver or sell or cause to be issued, delivered or sold any
additional Shares or any other capital stock of the Company or any other
securities convertible into, or exercisable or exchangeable for, or evidencing
the right to subscribe for any such Shares or other capital stock of the
Company.  As reflected on Section 3.2 of the Company Disclosure Schedule, the
exercise prices for all outstanding options, warrants or other rights to
acquire capital stock of the Company are at prices in excess of the Offer
price.

3.3      Authorization and Validity of Agreement.  The Company has the
requisite corporate power and authority to enter into this Agreement and to
consummate the transactions contemplated hereby in accordance with the terms
hereof (subject to the approval and adoption of this Agreement and the Merger
by the holders of a majority of the outstanding Shares, if required by
applicable law).  All members of the Company's Board of Directors (the "Company
Board") have duly authorized the execution, delivery and performance of this
Agreement by the Company, and no other corporate proceedings on the part of the
Company are necessary to authorize this Agreement or the transactions
contemplated hereby (other than the approval and adoption of this Agreement and
the Merger by the holders of a majority of the outstanding Shares, if required
by applicable law).  This Agreement has been duly executed and delivered by the
Company and, assuming this Agreement constitutes the legal, valid and binding
obligation of Parent and Purchaser, constitutes the legal, valid and binding
obligation of the Company, enforceable against the Company in accordance with
its terms, except as may be limited by any bankruptcy, insolvency,
reorganization, moratorium, fraudulent conveyance or other similar laws
affecting the enforcement of creditors' rights generally or by general
principles of equity (regardless of whether such enforceability is considered
in a proceeding in equity or at law).

3.4      Consents and Approvals.

         (a)     Neither the execution and delivery of this Agreement by the
Company nor the consummation by the Company of the transactions contemplated
hereby will require any consent, approval, authorization or permit of, or
filing with or notification to, any governmental or regulatory authority by
reason of the Company's status or operations, except (i) pursuant to the
applicable requirements of the Securities Act of 1933, as amended (the
"Securities Act"), and the rules and regulations promulgated thereunder, and
the Exchange Act, and the rules and regulations promulgated thereunder, and
state securities or "blue sky" laws and state takeover laws, (ii) the filing
and recordation of the Certificate of Merger pursuant to the DGCL and
appropriate documents with the relevant authorities of other states in which
the Company is authorized to do business, (iii) as set forth in Section 3.4 of
the Company Disclosure Schedule or (iv) where the failure to obtain such
consent, approval, authorization or permit, or to make such filing or
notification, would not in the aggregate have a Material Adverse Effect on the
Company.

         (b)     Each member of the Company Board has approved this Agreement
and the transactions contemplated hereby for purposes of Section 203 of the
DGCL so that Section 203 of the DGCL is not applicable to the transactions
provided for in this Agreement.  Unless the Merger is otherwise consummated as
contemplated by Section 2.13 hereof, the affirmative vote of the holders of a
majority of the outstanding Shares is the only vote of the holders of capital
stock of the Company necessary to approve the Merger.

3.5      No Violation.  Except as set forth in Section 3.5 of the Company
Disclosure Schedule, assuming the Merger has been duly approved by the holders
of a majority of the outstanding Shares or the Merger is consummated as
contemplated by Section 2.13 hereof, neither the execution and delivery of this
Agreement by the Company nor the consummation by the Company of the
transactions contemplated hereby will conflict with or violate the Certificate
of Incorporation or Bylaws of the Company,  result in a violation or breach of,
constitute a default under, give rise to any right of termination, cancellation
or acceleration of, or result in the imposition of any lien, charge or other
encumbrance on any material assets or property of the Company pursuant to, any
note, bond, mortgage, indenture, contract, agreement, lease, license or other
instrument or obligation to which the Company is a party or by which the
Company or any of its assets or properties may be bound, except for such
violations, breaches and defaults (or rights of termination, cancellation or
acceleration or lien or other charge or encumbrance) as to which requisite
waivers or consents have been obtained or which in the aggregate would not have
a Material Adverse Effect on the Company or  assuming the consents, approvals,
authorizations or permits and filings or notifications referred to in Section
3.4 and this Section 3.5 are duly and timely obtained or made and the approval
of the Merger by the holders of a majority of the outstanding Shares has been
obtained or the Merger is consummated as contemplated by Section 2.13 hereof,

applicable to the Company or any of its assets and properties, except for such
violations which would not in the aggregate have a Material Adverse Effect on
the Company.

Schedule, since January 1, 1997, the Company has filed with the SEC all forms,
reports, schedules, statements and other documents required to be filed by it
with the SEC pursuant to the Exchange Act, the Securities Act and the SEC's
rules and regulations thereunder (all such forms, reports and other documents,
including any such reports filed prior to the Effective Time, collectively, the
"Company SEC Documents").  The Company SEC Documents, including, without
limitation, any financial statements or schedules included therein, at the time
filed (or, if amended, at the time of such amended filing), or in the case of
registration statements on their respective effective dates, complied in all
material respects with the applicable requirements of the Exchange Act and the
Securities Act, as the case may be, and the applicable rules and regulations of
the SEC thereunder and  did not at the time they were filed (or, if amended, at
the time of such amended filing and, in the case of registration statements, at
the time of effectiveness), contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary in
order to make the statements made therein, in light of the circumstances under
which they were made, not misleading.

results of the Company's operations and cash flows for the periods presented

the Schedule 14D-9, the Company Proxy Statement nor any information supplied by
the Company specifically for inclusion in the Offer Documents will, at the
respective times filed with the SEC or first published, sent or given to
stockholders, as the case may be, or, in the case of the Company Proxy
Statement, at the date mailed to the Company stockholders and at the time of
the Company Stockholders' Meeting, contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading.  The Schedule 14D-9
and the Company Proxy Statement will, when filed by the Company with the SEC,
comply as to form in all material respects with the applicable provisions of
the Exchange Act and the rules and regulations thereunder.  Notwithstanding the
foregoing, the Company makes no representation or warranty with respect to the
statements made in any of the foregoing documents based on information supplied
by or on behalf of Parent or Purchaser or any of their respective affiliates
specifically for inclusion therein.

3.8      Compliance with Law.   The Company is not in violation of any
applicable law, rule, regulation, decree or order of any governmental or
regulatory authority applicable to the Company, except for violations which in
the aggregate do not have a Material Adverse Effect on the Company.  The
Company holds all permits, licenses, exemptions, orders and approvals of all
governmental and regulatory authorities necessary for the lawful conduct of its
businesses, except where the failures to hold permits, licenses, exemptions,
orders and approvals do not in the aggregate have a Material Adverse Effect on
the Company.

3.9      Absence of Certain Changes.   Except as disclosed in the Company SEC
Documents filed with the SEC prior to the date hereof or in Section 3.9 of the
Company Disclosure Schedule, since December 31, 1996, the Company has conducted
its business only in the ordinary course of such business and there has not

Section 3.10 of the Company Disclosure Schedule, there are no claims, actions,
proceedings or governmental investigations pending or, to the knowledge of the
Company, threatened against the Company, by or before any court or other
governmental or regulatory body, which, if adversely determined, would





                                      -11-

have a Material Adverse Effect on the Company.  As of the date hereof, to the
knowledge of the executive officers of the Company, no action or proceeding has
been instituted or threatened before any court or other governmental or
regulatory body by any Person (as defined in Section 8.3) seeking to restrain
or prohibit the execution, delivery or performance of this Agreement or the
consummation of the transactions contemplated hereby.

3.11     Employee Benefit Matters.  All employee benefit plans and other
benefit and compensation arrangements covering employees of the Company are
listed in Section 3.11 of the Company Disclosure Schedule (the "Company Benefit
Plans").  True and complete copies of the Company Benefit Plans, their related
trust and summary plan descriptions, and any reports, forms and documents
required to be filed or distributed for the preceding three years relating to
the Company Benefit Plans have been delivered to Parent.  To the extent
applicable, the Company Benefit Plans comply, in all material respects, with
the requirements of the Employee Retirement Income Security Act of 1974, as
amended ("ERISA"), and the Code, and any Company Benefit Plan and its related
trust intended to be qualified under Sections 401(a) and 501(a) of the Code
comply in form and in operation with Sections 401(a) and 501(a) of the Code.
No Company Benefit Plan is covered by Title IV of ERISA or Section 412 of the
Code.  There has been no transaction involving any Company Benefit Plan that
has resulted or would result in any liability or penalty under Section 4975 of
the Code or Section 502(i) of ERISA.  Each Company Benefit Plan has been
maintained and administered in all material respects in compliance with its
terms and with ERISA and the Code to the extent applicable thereto.  There are
no pending or anticipated material claims against or otherwise involving any of
the Company Benefit Plans and no suit, action or other litigation (excluding
claims for benefits incurred in the ordinary course of Company Benefit Plan
activities) has been brought against or with respect to any such Company
Benefit Plan, except for any of the foregoing that would not have a Material
Adverse Effect on the Company.  All contributions required to be made as of the
date hereof to the Company Benefit Plans have been made or provided for.
Neither the Company nor any entity under "common control" with the Company
within the meaning of Section 4001 of ERISA has contributed to or ever
maintained, or been required to contribute to or maintain, any employee pension
plan (as defined in Section 3(2) of ERISA) subject to Title IV of ERISA or
Section 412 of the Code or to any "multi-employer plan" (as defined in Sections
3(37) and 4001(a)(3) of ERISA).  Except as disclosed in Section 3.11 of the
Company Disclosure Schedule, the Company does not maintain or contribute to any
plan or arrangement that provides or has any liability to provide life
insurance, medical or other employee welfare benefits to any employee or former
employee upon his retirement or termination of employment, except as required
by Section 4980B of the Code, and the Company has never represented, promised
or contracted (whether in oral or written form) to any employee or former
employee that such benefits would be provided.  All insurance premiums have
been paid in full, subject only to normal retrospective adjustments in the
ordinary course, with regard to Company Benefit Plans for policy years or other
applicable policy periods ending before the closing and have been paid as
required under the policies for policy years or other applicable policy periods
beginning on or before the closing.  All expenses and liabilities relating to
all of Company Benefit Plans have been, and will on the Closing Date be, fully
and properly accrued on the Company's books and records and disclosed in
accordance with generally accepted accounting principles and in the Employee
Benefit Plan financial statements.  The Company does not have any agreement,
arrangement, commitments or understanding to create any additional plan which
would constitute an Employee Benefit Plan or to increase the rate of benefit
accrual or contribution requirements under any of the Employee





                                      -12-
<PAGE>   17
Benefit Plans or to modify, change or terminate in any respect any existing
Employee Benefit Plan.  None of the Employee Benefit Plans is currently under
investigation, audit, or review by the Department of Labor, the Internal
Revenue Service or any other federal or state agency, and no violations of the
Code or ERISA have been alleged by any such agency with respect to such
Employee Benefit Plans.  The Employee Benefit Plans may be amended or
terminated at any time. Except as disclosed in Section 3.11 of the Company
Disclosure Schedule, the execution of, and performance of the transactions
contemplated in, this Agreement will not (either alone or upon the occurrence
of any additional or subsequent events) constitute an event under any benefit
plan, policy, arrangement or agreement or any trust or loan that will or may
result in any payment (whether of severance pay or otherwise), acceleration,
forgiveness of indebtedness, vesting, distribution, increase in benefits or
obligations to fund benefits with respect to any employee.  The consummation of
the transactions contemplated by this Agreement, either alone or in combination
with another event, has not resulted in and will not result in payments to
"disqualified individuals" (as defined in Section 280G(c) of the Code) of the
Company which, individually or in the aggregate, will constitute "excess
parachute payments" (as defined in Section 280G(b) of the Code) resulting in
the imposition of excise tax under Section 4999 of the Code or will result in
the disallowance of deductions under Sections 162 (m) or 280G of the Code.

5.4      Notice of Certain Matters.  The Company shall give prompt notice to
Parent, and Parent and Purchaser shall give prompt notice to the Company, of

5.6      State Takeover Statutes.  The Company, Parent and Purchaser will
cooperate to take reasonable steps to (a) exempt the Offer and the Merger from
the requirements of any applicable state takeover law and (b) assist in any

5.7      Cooperation.   Subject to the terms and conditions of this Agreement
and applicable law, each of the parties shall act in good faith and use
reasonable efforts to take, or cause to be taken, all actions, and to do, or
cause to be done, all things necessary, proper or advisable to consummate and

respective affiliates, directors, officers, employees, agents, attorneys,

efforts to cause the lifting of any permanent or preliminary injunction or
restraining order or other similar order issued or entered by any court or
other Governmental Entity preventing or restricting consummation of the
transactions contemplated hereby in the manner provided for herein.  Prior to
making any application to or filing with any Governmental Entity or other
Person in connection with this Agreement, each party shall provide the other
party with drafts thereof and afford the other party a reasonable opportunity
to comment on such drafts.

5.8      Public Announcements.  No party hereto shall or shall permit any of
its subsidiaries to (and each party shall use commercially reasonable efforts
to cause its affiliates, directors, officers, employees, agents or
representatives not to) issue any press release or make any public statement
concerning this Agreement or any of the transactions contemplated hereby,
without the prior written consent of the other parties hereto; provided,
however, that a party may, without the prior written consent of the other party
hereto, issue such a press release or make such a public statement to the
extent required by applicable law or any listing agreement with a national
securities exchange by which such party is bound if it has used commercially
reasonable efforts to consult with the other parties and to obtain such
parties' consent but has been unable to do so in a timely manner.

5.9      Acquisition Proposals.  Except as contemplated hereby, the Company
shall not (and shall use its best efforts to cause its officers, directors and
employees and any investment banker, financial advisor, attorney, accountant,
or other agent or representative retained by it not to) directly or indirectly,
initiate, solicit or encourage (including by way of furnishing information or
assistance), or take any other action to facilitate, any inquiries or the
making of any proposal relating to, or that may reasonably be expected to lead
to, the acquisition of all or a significant part of the business and properties
or capital stock of the Company, whether by merger, purchase of assets, tender
offer or otherwise with a third party other than Parent (an "Acquisition
Proposal"), or enter into discussions or negotiate with any person or entity in
furtherance of such inquiries or to obtain an Acquisition Proposal, or agree to
or endorse any Acquisition Proposal, or authorize or permit any of the
officers, directors, employees or agents of the Company or any investment
banker, financial advisor, attorney, accountant or other representative
retained by the Company to take any such action.  The Company shall as promptly
as practicable notify Parent of all relevant terms of any such inquiries or
proposals received by the Company and, if such inquiry or proposal is in
writing, the Company shall as promptly as practicable deliver or cause to be
delivered to Parent a copy of such inquiry or proposal.  Notwithstanding the
foregoing, nothing shall prohibit the Company's Board of Directors from (a)
furnishing information to, or entering into discussions or negotiations with,
any persons or entity in connection with an unsolicited bona fide proposal in
connection with an Acquisition Proposal if, and only to the extent that (i)
such unsolicited bona fide proposal is on terms that the Company's





                                      -28-
<PAGE>   33
Board of Directors determines it cannot reject, based on applicable fiduciary
duties and the advice of outside counsel (except with respect to furnishing
information) and for which financing, to the extent required, is then
committed, and (ii) prior to furnishing such information to or entering into
discussions or negotiations with, such person or entity the Company provides
written notice to Parent to the effect that it is furnishing information to, or
entering into discussions or negotiations with, such person or entity; or (b)
complying with Rule 14d-9 or Rule 14e-2 promulgated under the Exchange Act with
regard to an Acquisition Proposal.

5.10     D&O Indemnification.

         (a)     From the Effective Time through the later of (i) the sixth
anniversary of the date on which the Effective Time occurs and (ii) the
expiration of any statute of limitations applicable to any claim, action, suit,
proceeding or investigation referred to below, the Surviving Corporation shall
indemnify and hold harmless each present and former director and officer of the
Company, determined as of the Effective Time (the "Indemnified Parties"),
against any claims, losses, liabilities, damages, judgments, fines, fees, costs
or expenses, including without limitation attorneys' fees and disbursements
(collectively, "Costs"), incurred in connection with any claim, action, suit,
proceeding or investigation, whether civil, criminal, administrative or
investigative, arising out of or pertaining to matters existing or occurring at
or prior to the Effective Time (including, without limitation, the Merger, the
preparation, filing and mailing of the Proxy Statement and the other
transactions and actions contemplated by this Agreement), whether asserted or
claimed prior to, at or after the Effective Time, to the fullest extent that
the Company would have been permitted, under applicable law, indemnification
agreements existing on the date hereof, the Certificate of Incorporation or
Bylaws of the Company in effect on the date hereof, to indemnify such Person
(and the Surviving Corporation shall also advance expenses as incurred to the
fullest extent permitted under applicable law provided the person to whom
expenses are advanced provides an undertaking to repay such advances if it is
ultimately determined that such person is not entitled to indemnification).

         (b)     Any Indemnified Party wishing to claim indemnification under
this Section 5.10, upon learning of any such claim, action, suit, proceeding or
investigation, shall promptly notify the Surviving Corporation thereof, but the
failure to so notify shall not relieve the Surviving Corporation of any
liability or obligation it may have to such Indemnified Party except, and only
to the extent, that such failure materially prejudices the Surviving
Corporation.  In the event of any such claim, action, suit, proceeding or
investigation (whether arising before, at or after the Effective Time), the
Surviving Corporation shall have the right to assume the defense thereof and
the Surviving Corporation shall not be liable to such Indemnified Parties for
any legal expenses of other counsel or any other expenses subsequently incurred
by such Indemnified Parties in connection with the defense thereof, except that
if the Surviving Corporation elects not to assume such defense or counsel for
the Indemnified Parties advises that there are issues that raise conflicts of
interest between the Surviving Corporation and the Indemnified Parties, the
Indemnified Parties may retain counsel satisfactory to them, and the Surviving
Corporation shall pay all reasonable fees and expenses of such counsel for the
Indemnified Parties promptly as statements therefor are received. If such
indemnity is not available with respect to any Indemnified Party, then the
Surviving Corporation and the Indemnified Party shall contribute to the amount
payable in such proportion as is appropriate to reflect relative faults and
benefits.  In the event that any claim or claims are asserted





                                      -29-
<PAGE>   34
or made within the aforesaid six-year period, all rights to indemnification in
respect of any such claim or claims shall continue until the final disposition
of any and all such claims.

         (c)     Notwithstanding anything herein to the contrary, if any claim,
action, suit, proceeding or investigation (whether arising before, at or after
the Effective Time) is made against any present or former director or officer
of the Company, on or prior to the sixth anniversary of the Effective Time, the
provisions of this Section 5.10 shall continue in effect until the final
disposition of such claim, action, suit, proceeding or investigation.

         (d)     This covenant is intended to be for the benefit of, and shall
be enforceable by, each of the Indemnified Parties and their respective heirs
and legal representatives.  The indemnification provided for herein shall not
be deemed exclusive of any other rights to which an Indemnified Party is
entitled, whether pursuant to law, contract or otherwise.

         (e)     To the extent that the Surviving Corporation fails to perform
any of its obligations pursuant to this Section 5.10, Parent shall assume the
obligations and rights of the Surviving Corporation under this Section 5.10.

5.11     Employee Matters.

         (a)     The Company will terminate all of its employees effective
immediately prior to the Closing Date, and the Company and the Surviving
Corporation shall pay all such terminated employees any and all benefits earned
under the Company Benefit Plans in accordance with their terms including any
amounts owing under any employment agreement or severance agreement, as
described in Section 3.11 of the Company Disclosure Schedule.

         (b)     Prior to the Closing Date, the Company shall take any and all
action necessary to terminate the HarCor Energy 401(k) Savings Plan ("HarCor
Savings Plan") with such termination to be effective immediately prior to the
Closing Date, and upon the termination of the HarCor Savings Plan, the Company
and the Surviving Corporation shall distribute to all HarCor Savings Plan
participants their account balances thereunder as soon as administratively
possible.

         (c)     Except for those Company Benefit Plans which the Parent
advises the Company in writing within 30 days following the date of this
Agreement that the Parent wishes to remain in effect following the Closing
Date, the Company shall take any and all action necessary to terminate all
Company Benefit Plans on or before the Closing Date.

         (d)     Notwithstanding the above, Parent shall be freely able to
contract with or employ, as the case may be, any terminated employee of the
Company without restriction or interference by the Company.

breach or failure to strictly comply with the provisions of this Agreement.

to assert any of its rights or remedies hereunder or with respect hereto shall
not constitute a waiver of such rights or remedies.

Agreement are for reference purposes only and shall not affect in any way the

                            CONDITIONS TO THE OFFER

         Capitalized terms used in this Annex A shall have the meanings
assigned to them in the Agreement to which it is attached (the "Merger
Agreement").

for any Shares tendered and Parent may terminate or, subject to the terms and
conditions of the Merger Agreement, amend the Offer as to any Shares not then
accepted for payment, shall not be required to accept for payment or pay for
any Shares, or may delay the acceptance for payment of Shares tendered, if (1)
at the expiration of the Offer, the number of Shares validly tendered and not

affiliates, shall not constitute a majority of the outstanding Shares on a
fully diluted basis or (2) at any time after the date of execution of the
Merger Agreement and prior to the acceptance for payment of Shares, any of the
following events shall occur:

                 (a)      there shall have been any action or proceeding
         brought by any governmental authority before any federal or state
         court, or any order or preliminary or permanent injunction entered in
         any action or proceeding before any federal or state court or
         governmental, administrative or regulatory authority or agency,

         action taken, proposed or threatened, or statute, rule, regulation,
         legislation, interpretation, judgment or order proposed, sought,
         enacted, entered, enforced, promulgated, amended, issued or deemed
         applicable to Purchaser, the Company or affiliate of Purchaser or the
         Company or the Offer or the Merger, by any legislative body, court,
         government or governmental, administrative or regulatory authority or
         agency located or having jurisdiction within the United States, which
         could reasonably be expected to have the effect of: (i) making
         illegal, materially delaying or otherwise restraining or prohibiting
         the Offer or the Merger or the acquisition by Parent or Purchaser of
         any Shares; (ii) prohibiting or materially limiting the ownership or
         operation by Parent, Purchaser or their respective affiliates of any
         material portion of their business or assets or those of the Company
         or compelling Parent or Purchaser to dispose of or hold separate all
         or any material portion of their business or assets or those of the
         Company, in each case as a result of the transactions contemplated by
         the Merger Agreement; (iii) imposing material limitations on the
         ability of Parent or any of its affiliates to exercise full rights of
         ownership of the Shares, including, without limitation, the right to
         vote any Shares purchased by them on all matters properly presented to
         the stockholders of the Company; or (iv) preventing Parent or any of
         its affiliates from acquiring, or to require divestiture by Parent or
         any of its affiliates of, any Shares; or

                 (b)      there shall have occurred (i) any general suspension
         of, or limitation on prices for, trading in securities on any national
         securities exchange or in the over-the-counter market in the United
         States, (ii) the declaration of any banking moratorium or any
         suspension of payments in respect of banks or any limitation (whether
         or not mandatory) on the extension of credit by lending institutions
         in the United States, (iii) the commencement or any escalation of a
         war, material armed hostilities or any other material international or





                                      A-1
<PAGE>   44
         national calamity involving the United States,  or (iv) in the case of
         any of the foregoing existing at the time of the commencement of the
         Offer, a material acceleration or worsening thereof; or

                 (c)      any Person, entity or "group" (as such term is used
         in Section 13(d)(3) of the Exchange Act) other than Parent or any of
         its affiliates shall have become the beneficial owner (as that term is
         used in Rule 13d-3 under the Exchange Act) of more than 50% of the
         outstanding Shares; or

                 (d)      the Company shall have breached or failed to comply
         in any material respect with any of its obligations under the Merger
         Agreement (which breach, if curable, has not been cured within thirty
         (30) days following receipt of written notice thereof by Parent
         specifying in reasonable detail the basis of such alleged breach), or
         any representation or warranty of the Company contained in the Merger
         Agreement that is qualified as to materiality shall not have been true
         and correct and any such representation and warranty that is not so
         qualified shall not have been true and correct in any material
         respect, except (i) for changes specifically permitted or contemplated
         by the Merger Agreement and (ii) those representations and warranties
         that address matters only as to a particular date which are true and
         correct as of such date; or

                 (e)      the Merger Agreement shall have been terminated
         pursuant to its terms or amended pursuant to its terms to provide for
         such termination or amendment of the Offer; or

                 (f)      the Board of Directors of the Company shall have
         modified or amended in any manner materially adverse to Parent or
         Purchaser or shall have withdrawn its recommendation of the Offer or
         the Merger, or shall have resolved to do any of the foregoing; or

                 (g)      Parent shall not have received notice from the holder
         or holders of more than 5%, on a fully diluted basis of the Shares
         issued and outstanding on the record date for the determination of
         stockholders entitled to vote on the Merger that such holders have
         exercised or intend to exercise their appraisal rights under the DGCL;
         or

                 (h)      the Company shall not have received at least
         $12,789,000 (including all material purchase price adjustments) in
         immediately available funds from the sale of the Company's
         non-California oil and gas assets and shall be entitled to receive an
         additional amount in immediately available funds determined under the
         Company's agreement with Penroc Oil Company ("Penroc") dated January
         15, 1998 for the sale of the Beaurline No. 9 well, Beaurline/McAllen
         Ranch Area, South Texas and its pooled or allocated producing unit
         (the "Well") as follows:  if the Well is restored by sidetrack or
         redrill or associated operations, an agreed amount equal to the
         present value of the future production from the Well discounted at
         10%, as determined by Ryder Scott Company (the "New Reserve
         Evaluation"), with payment to be made ten business days after Penroc's
         receipt of the New Reserve Evaluation; or





                                      A-2
<PAGE>   45
                 (i)      the Company shall not have retained the proceeds from
         the sale of its non-California oil and gas assets or used such
         proceeds to repay Company indebtedness or other liabilities incurred
         by the Company in the ordinary course of business or pursuant to the
         transactions contemplated by the Merger Agreement; or

                 (j)      the Company shall have completed and delivered to
         Parent an audit of the Company's financial statements for the fiscal
         year ended December 31, 1997, to be performed by the accounting firm
         of Arthur Andersen LLP, which reveals material adverse information not
         previously disclosed in writing to Parent, or a material variance from
         the written or printed disclosures furnished by the Company or its
         representatives and used by Parent in its economic models; or

                 (k)      there shall have occurred any event, change, effect
         or development having a Material Adverse Effect on the Company;

which, in the good faith judgment of Parent makes it inadvisable to proceed
with the Offer or with acceptance for payment or payment for Shares.

         The foregoing conditions are for the sole benefit of Parent and
Purchaser and may be asserted or waived by Parent or Purchaser in whole or in
part at any time or from time to time in its discretion subject to the terms
and conditions of the Merger Agreement.  The failure of Parent or Purchaser at
any time to exercise any of the foregoing rights shall not be deemed a waiver
of any such right and each such right shall be deemed an ongoing right which
