THIS AMENDMENT NO. 1 RELATES TO THE SCHEDULE 13D ORIGINALLY FILED ON BEHALF OF
THE REPORTING PERSON WITH THE SECURITIES AND EXCHANGE COMMISSION (THE
"COMMISSION") ON MAY 22, 1998. CAPITALIZED TERMS USED BUT NOT DEFINED HEREIN
SHALL HAVE THE RESPECTIVE MEANINGS SET FORTH IN SAID SCHEDULE 13D. THE TEXTS OF
ITEMS 3, 4 AND 5 OF SAID SCHEDULE 13D ARE HEREBY AMENDED AS FOLLOWS:

ITEM 3.       SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         Lomak may be deemed to have acquired beneficial ownership of an
aggregate of 7,820,718 shares of Domain Common Stock (the "Shares") pursuant to
the terms of Voting and Standstill Agreement (the "Voting and Standstill
Agreement") dated May 12, 1998, by and between Lomak and First Reserve Fund VII,
Limited Partnership, a Delaware limited partnership ("FRLP").

         In addition, on the terms and subject to the conditions set forth in
the Stock Purchase Agreement (the "Stock Purchase Agreement") dated May 12,
1998, by and between Lomak and FRLP, Lomak has agreed to acquire, and FRLP has
agreed to sell, 3,250,000 shares of Domain Common Stock on July 1, 1998 pursuant
to the Stock Purchase Agreement in consideration for $43,875,000 in cash. The
consummation of the Merger described below is contingent upon the consummation
of the purchase under the Stock Purchase Agreement, but not vice versa.

         Lomak currently intends to fund the acquisition of such shares under
the revolving credit facility of that certain $400,000,000 Credit Agreement
dated as of February 14, 1997 by and among Lomak, as Borrower, and the several
lenders from time to time parties thereto, including Bank One, Texas, N.A. as
Administrative Agent, The Chase Manhattan Bank, as Syndication Agent, and
NationsBank of Texas, N.A., as Documentation Agent (the "Credit Agreement"). As
of May 20, 1998, Lomak had approximately $102 million of available borrowing
capacity under the Credit Agreement. The Credit Agreement is filed as Exhibit D
hereto, and is incorporated herein by reference.

         Furthermore, on the terms and subject to the condition set forth in the
Agreement and Plan of Merger (as amended, the "Merger Agreement") dated May 12,
1998, by and among Lomak, DEC Acquisition, Inc., a Delaware corporation and
wholly owned subsidiary of Lomak ("Merger Sub"), and Domain, Lomak will acquire
100% of the remaining equity interest in Domain that is not purchased by Lomak
under the Stock Purchase Agreement.

         The descriptions of the Voting and Standstill Agreement, Stock Purchase
Agreement and the Merger Agreement set forth in this Item 3 and in Item 4 do not
purport to be complete and are qualified in their entirety by reference to the
respective agreements, copies of which are attached as Exhibits A, B, and C,
respectively. Furthermore, the descriptions of the Voting and Standstill
Agreement, Stock Purchase Agreement and the Merger Agreement set forth in Item 4
hereof are incorporated herein by reference.

         On June 5, 1998, Lomak announced that its Board of Directors had
approved the purchase from time to time, in open market purchases or negotiated
sales, of shares Domain Common Stock or Lomak Common Stock, provided that the
aggregate purchase price of such shares may not exceed $25 million. Purchases of
shares pursuant to this purchase program (the "Purchase

Program") will be funded with internally generated funds and borrowings under
the Credit Agreement. As required by the terms of the confidentiality agreement
between Lomak and Domain dated March 31, 1998, the Board of Directors of Domain
has consented to the purchase of shares of Domain Common Stock under the
Purchase Program.

         On June 10, 1998, Lomak made its first purchases of Domain Common Stock
under the Purchase Program. Through June 12, 1998, Lomak had acquired an
aggregate of 279,100 shares of Domain Common Stock under the Purchase Program
for an aggregate consideration of $3,355,025 (excluding aggregate brokerage
commissions of $13,955).

ITEM 4.       PURPOSE OF TRANSACTION.

         The respective Boards of Directors of Lomak and Domain have determined
that the Merger is in the best interests of their respective stockholders. On
the terms and subject to the conditions set forth in the Merger Agreement,
Merger Sub will merge into Domain (the "Merger") at the effective time of the
Merger, with Domain surviving as a wholly owned subsidiary of Lomak. Pursuant to
the Merger Agreement, Domain's stockholders will receive a number of shares (the
"Exchange Ratio") of common stock, par value $.01 per share ("Lomak Common
Stock") for each share of Domain Common Stock equal to (i) $14.50 divided by
(ii) the "Closing Date Market Price" of Lomak Common Stock. However, the
Exchange Ratio will not be greater than 1.2083 nor less than 0.8529. For
purposes of the Merger Agreement, the "Closing Date Market Price" is the average
of the closing prices of the Lomak Common Stock on the New York Stock Exchange
for the 15 trading days prior to the third business day prior to the effective
time of the Merger. Simultaneously with the effective time of the Merger, Lomak
will change its corporate name to "Range Resources Corporation," subject to the
approval by the holders of a majority of the outstanding shares of Lomak Common
Stock.

         As a condition to Lomak's entering into the Merger Agreement, Lomak
required that FRLP enter into the Stock Purchase Agreement and the Voting and
Standstill Agreement. Pursuant to the Voting and Standstill Agreement, FRLP has,
among other things, agreed to vote all shares of Domain Common Stock
beneficially owned by FRLP in favor of the Merger Agreement and against any
business combination proposal or other matter that may interfere or be
inconsistent with the Merger (including a competing transaction). FRLP also has
agreed, if requested by Lomak, not to attend and not to vote any Domain Common
Stock beneficially owned by FRLP at any annual or special meeting of Domain
stockholders and not to execute any written consent of stockholders, in each
case relating directly or indirectly to a competing transaction.

         The Voting and Standstill Agreement also provides that neither FRLP nor
any other member of the FRLP Group (as defined in the Voting and Standstill
Agreement) will initiate, solicit or encourage any offer or proposal for, or any
indication of interest in, a merger or other business combination directly or
indirectly involving Domain or any subsidiary of Domain, or the acquisition of a
substantial equity interest in, or a substantial portion of, the assets of, any
third party, other

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

than the transactions contemplated by the Merger Agreement or the Voting and
Standstill Agreement ("Domain Acquisition Proposal").

         FRLP also has agreed that it will not, directly or indirectly, (i)
sell, transfer, pledge or otherwise dispose of any shares of Domain to any
person other than Lomak or its designee, or (ii) grant a proxy with respect to
any shares of Domain to any person other than Lomak or its designee, or grant an
option with respect to any of the foregoing, or enter into any other agreement
or arrangement with respect to any of the foregoing. Notwithstanding the
foregoing, FRLP is permitted to sell up to 1% in the aggregate of the number of
outstanding shares of Domain Common Stock under certain circumstances if the
Closing Date Market Price is greater than $17.00 per share.

         The Voting and Standstill Agreement will terminate on the second
anniversary of the consummation of the Merger or by mutual written agreement of
the parties.

         As required by the Voting and Standstill Agreement, FRLP has executed a
written stockholder consent approving of the Merger in accordance with Section
228 of the Delaware General Corporation Law (the "DGCL"). As a result, Domain
has represented to Lomak in the Merger Agreement that no further Domain
stockholder approval is required in connection with the transactions
contemplated by the Merger Agreement. Completion of the transaction is
contingent upon certain customary closing conditions, including the approval of
the issuance of the Lomak Common Stock in the Merger by a majority of the
holders of Lomak Common Stock present in person or by proxy at a stockholder
meeting at which a quorum is present.

         The Board of Directors of Lomak has approved the Purchase Program in
furtherance of the transactions contemplated by the Merger Agreement. In
announcing the Purchase Program on June 5, 1998, John H. Pinkerton, President
and Chief Executive Officer of Lomak, stated the following:

              We believe [Lomak's] stock price does not adequately reflect the
              value of [Lomak's] assets and future prospects and that [Lomak's]
              shares are trading at a significant discount to those of
              comparable independents. Given the terms of the proposed merger,
              Domain's shares are trading at an even greater discount. Due to
              the recent drop in oil prices, we have decided to reallocate
              capital from certain of [Lomak's] development projects to stock
              repurchases.

ITEM 5.       INTEREST IN SECURITIES OF THE ISSUER

         (a) According to Domain's Quarterly Report on Form 10-Q for the period
ended March 31, 1998, there were 15,107,719 shares of Domain Common Stock issued
and outstanding. Lomak may be deemed to be the beneficial owner of the 8,099,818
Shares, which constitute approximately 53.6% of the total issued and outstanding
shares of Domain Common Stock at May 12, 1998.

         (b) Pursuant to the terms of the Voting and Standstill Agreement, Lomak
could be deemed to share power to direct the vote of the 7,820,718 Shares
subject to such agreement with FRLP and to share power to direct the disposition
of such Shares with FRLP. Lomak could also be deemed to share voting and
dispositive power with FRLP with respect to the 3,200,000 Shares that are
subject to the Stock Purchase Agreement. Lomak has sole voting and dispositive
power with respect to the Shares purchased pursuant to the Purchase Program.

         (c) During the past 60 days, except as described above with respect to
the Voting and Standstill Agreement and the Stock Purchase Agreement and except
for the open market purchases pursuant to the Purchase Program set forth below,
Lomak has not acquired beneficial ownership of any other shares of Domain Common
Stock. The purchases set forth below were effected in brokerage transactions
effected on the open market:
