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

        The 5,254,353 shares of the Company's Common Stock referred to herein
were distributed to PPM by the Company pursuant to the consummation of its Plan
of Reorganization under Chapter 11 of the United States Bankruptcy Code on
account of the claims held by SIF I and CBO II against the Company in that
proceeding. Such claims arose from their prior ownership of $51,305,000
aggregate principal amount of the Company's 8 7/8% Senior Subordinated Notes,
due 2007 (the "Old Notes"), which were extinguished pursuant to the terms of the
Plan of Reorganization.

        SIF I and CBO II did not pay additional consideration for the shares of
Common Stock which they received pursuant to the Company's Plan of
Reorganization. The source of funds which they used for their respective prior
purchases of the Company's Old Notes was funds previously invested in SIF I and
CBO II, respectively, by the limited partners of SIF I and CBO II and the
purchasers of debt of SIF I and CBO II.

Item 4. Purpose of Transaction.
        ----------------------
        As described in the response to Item 3 above, the shares beneficially
owned by PPM were acquired pursuant to the terms of the Company's Plan of
Reorganization on account of claims in the Company's Chapter 11 proceeding. PPM
intends to hold the shares for investment purposes. PPM may acquire additional
shares, dispose of some or all of the shares from time to time, in each case in
open market transactions, block sales or purchases or otherwise, or may continue
to hold all of the shares. PPM may also dispose of some or all of the shares in
one or more registered public offerings pursuant to the terms of the
Registration Rights Agreement described in the response to Item 6 below.
<PAGE>

  So long as PPM and its affiliates collectively are one of the largest
shareholders of the Company, PPM may seek to influence the control of the
Company.

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

  Based upon information acquired from the Company, there were a total of
16,002,195 shares of Common Stock outstanding as of April 10, 2000. Therefore,
PPM's beneficial ownership of shares constitutes approximately 32.84% of the
issued and outstanding Common Stock. As of the date of hereof:

  SIF I beneficially owned 2,374,163 shares of Common Stock, constituting
approximately 14.84% of the issued and outstanding shares of the Company's
Common Stock. SIF I shares voting and dispositive power with respect to these
2,374,163 shares of Common Stock with SIF I GP, its managing general partner and
PPM America, which serves as its investment advisor/manager.

  CBO II beneficially owned 2,880,190 shares of Common Stock, constituting
approximately 18.00% of the issued and outstanding shares of the Company's
Common Stock. CBO II shares voting and dispositive power with respect to these
2,880,190 shares of Common Stock with CBO II GP, its general partner and PPM
America, which serves as its investment advisor/manager.

  Reference is made to the response to Item 6 below, which is hereby
incorporated herein, for a description of additional shares of Common Stock
which are to be issued to SIF I and CBO II in the future pursuant to the terms
of the Securities Purchase Agreement described therein.

   (c) PPM has not effected any transactions in the Common Stock during the
sixty days preceding the date of this Schedule 13D.

   (d) Not applicable.

   (e) Not applicable.

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

   PPM is a party to two agreements which relate to Common Stock of the Company,
a Securities Purchase Agreement and a Registration Rights Agreement, which are
each described below. In addition, PPM was one of three bondholder members of
the Official Committee of Unsecured Creditors in the Company's Chapter 11
proceeding (the "Committee"). The Committee in turn was a co-proponent of the
Company's Plan of Reorganization which was consummated in that proceeding.
Pursuant to the terms of the Plan of Reorganization, which was confirmed by the
United States Bankruptcy Court for the Southern District of Texas pursuant to an
order entered on March 20, 2000, the Company's certificate of incorporation and
by-laws were amended and restated in their entirety and the three bondholder
members of the Committee collectively designated four members of the Company's
new seven member board of directors for the first year of its tenure. To date
the bondholder members of the Committee have designated three such directors:
Eugene Davis, James Bolin and John Graham. Pursuant to the terms of the Plan,
the Committee's existence terminated for all practical purposes at midnight on
March 31, 2000. A copy of the Plan of Reorganization is attached as Exhibit I.

   SIF I and CBO II are also parties to a Securities Purchase Agreement dated as
of March 31, 2000 pursuant to which the Company issued $72 million principal
amount of its 15% Senior Subordinated Notes due March 31, 2007 ("New Senior
Notes") in connection with the consummation of the Company's Plan of
Reorganization. Pursuant to that agreement, the Company will issue, for no
further consideration, additional shares of its Common Stock equal to an
aggregate of 14.4% of the outstanding Common Stock of the Company, calculated on
a fully diluted basis, to the purchasers of its Senior Notes on the earlier to
occur of the closing of a pending rights offering by the Company, if the Company
is able to include such additional shares in its registration statement for the
rights offering, or six months after consummation of such rights offering.
Without giving effect to increases in the number of shares which may be issued
pursuant to antidilution adjustments which cannot be calculated at this time,
SIF I will receive 672,989 additional shares of Common Stock and CBO II will
receive 803,849 additional shares of Common Stock pursuant to the Securities
Purchase Agreement. Under the terms of the Plan of Reorganization, the
purchasers of the New Senior Notes collectively were also entitled to designate
two additional members of the new board of directors of the Company for the
first year of its tenure. The directors so designated were Ronald Goldstein and
Michael Salvati. A copy of the Securities Purchase Agreement is attached hereto
as Exhibit II.

   SIF I and CBO II are also parties to a Registration Rights Agreement with the
Company pursuant to which the Company has granted the following registration
rights with respect to all of the shares of Common Stock which are the subject
of this filing as well as all of the shares of Common Stock to be issued
pursuant to the Securities Purchase Agreement referred to above:
<PAGE>

       (i)   The Company will use its best efforts to cause a shelf registration
statement for all such shares of Common Stock to be declared effective by March
31, 2001, and to remain effective until the earlier of March 31, 2004, the
disposition of all such shares or such time as all such shares can be sold by
the parties to such agreement without restriction under the Securities Act of
1933;

       (ii)  After March 31, 2001, the holder or holders of at least 10 percent
of the Common Stock which is subject to such agreement may require the Company
to file a registration statement with respect to such stock;

       (iii) Each time the Company files a registration statement with respect
to any offering of shares of its Common Stock, the parties to such agreement
may, subject to certain limitations, require the inclusion of their shares of
Common Stock in the offering; and

        (iv) At any time when the Company is entitled to use Form S-3 under the
Securities Act of 1933 or any successor form thereto to register shares of
Common Stock held by a party to such agreement, the parties to such agreement
have the right to request the Company to use commercially reasonable efforts to
register their shares of Common Stock on such form.

        The responses set forth in Items 4 and 5 of this Schedule are also
incorporated herein by this reference in their entirety. A copy of the
Registration Rights Agreement is attached hereto as Exhibit III.

title 11, United States Code, for the resolution of the Debtors' outstanding
Creditor Claims and Equity Interests.

                                    ARTICLE I

                              SUMMARY OF THIS PLAN

      Capitalized terms used in the following summary are as defined in Article
II, the Definitions, Construction and Interpretation portion of this Plan.

      This Plan provides for the treatment of all Claims in a manner that is in
the best interests of Creditors and is fair and equitable. This Plan also
provides for fair and equitable treatment of holders of Equity Interests in the
Parent Company. This summary deals with certain major elements of this Plan.

      This Plan provides for the treatment of the Allowed Bank Group Claim of
approximately $240 million of principal (plus accrued interest and reasonable
fees and expenses) as a Fully Secured Claim. On the Effective Date the Allowed
Bank Group Claim will be paid in full in Cash. The Parent Company will obtain
the funds necessary for the payment of the Allowed Bank Group Claim through the
combination of (i) the Credit Facility, (ii) either the Rights Offering or the
Private Placement, (iii) cash on hand from the Debtor's operations and (iv) the
Standby Loan, if necessary.

      Under this Plan, approximately $162 million of Allowed Bond Claims will be
paid in full by issuing the holders of Existing Bonds 96% of the New Common
Stock of the Reorganized Parent Company on the Effective Date of the Plan. The
ownership percentage of the holders of Allowed Bond Claims may be diluted by (i)
the Rights Offering or the Private Placement and (ii) the Standby Loan, if
necessary.

      Holders of Existing Common Stock in the Parent Company as of the Voting
Record Date will be issued 4% of the shares of the New Common Stock on the
Effective Date and holders of Existing Common Stock as of the Rights Offering
Record Date will receive rights to purchase additional shares of New Common
Stock under the Rights Offering, which will be made in a separate prospectus
sent to such holders of Existing Common Stock. The ownership percentage of the
holders of Existing Common Stock may be diluted by (i) either the Rights
Offering or the Private Placement and (ii) the Standby Loan, if necessary.

      To implement this Plan, the Reorganized Debtors will raise up to $90
million of new investment in the Reorganized Parent Company by (i) either the
Rights Offering or the Private Placement, and (ii) if applicable, the Standby
Loan. Under the Rights Offering, which will be made pursuant to a separate
prospectus, holders of Existing Common Stock as of the Rights Offering Record
Date will have the exclusive first opportunity to buy additional shares of the
New Common Stock for a price of $0.26 per current share, up to an aggregate of
$90 million. Holders of Existing Common Stock as of the Rights Offering Record
Date who wish to purchase more than their allocable portion of the shares
offered to them in the Rights Offering may do so, to the extent that other
shareholders do not elect to participate in the Rights Offering. If the Rights
Offering is not fully subscribed up to $90 million by holders of Existing Common
Stock as of the Rights Offering Record Date, then the Parent Company may offer
the remaining shares of the New Common Stock to third parties pursuant to the
Rights Offering. In connection with the Rights Offering, the Parent Company
filed a registration statement with the SEC to register the Rights and to
register shares of New Common Stock under the Rights Offering. If the lithe
registration statement filed with the SEC is not declared effective by a date
sufficiently early to give the Parent Company adequate time to arrange and
complete the Rights Offering the Parent Company will, in its sole discretion,
discontinue the Rights Offering and proceed with the Private Placement. The
Rights Offering or Private Placement will be arranged by Jefferies & Company,
Inc., or another investment banker, subject to the approval of the Bankruptcy
Court. Jefferies & Company, Inc., or another investment banker, will be retained
by the Parent Company for the limited purpose of arranging the Rights Offering
or Private Placement and not as a general financial advisor to the Debtors.

      To the extent that the proceeds of the Rights Offering or the Private
Placement are less than $90 million, the Debtors will issue, and the Standby
Lenders will purchase, an amount of senior subordinated notes to be determined
by the Reorganized Parent Company. This amount will be a maximum of $70 million
given the current level of commitment under the Standby Loan and a maximum of
$90 million if more Standby Loan commitments are obtained and made available
before the conclusion of the Confirmation Hearing, or the Effective Date if the
Debtors choose to extend the Rights Offering to that date. Payment of the
Standby Loan Notes will be expressly subordinate to the full and final payment
in cash of all obligations arising in connection with the Credit Facility and
payments made under the Standby Loan will be subject to the consent of Chase.
The Standby Loan is not conditioned on any minimal Rights Offering subscription
or Private Placement sale.

      If the Reorganized Parent Company draws on the Standby Loan, the Standby
Lenders will receive the Standby Shares. If $70 million in principal amount of
the Standby Loan Notes are issued, the Standby Lenders will receive 14% of the
fully diluted New Common Stock. The amount of Standby Shares issued will be
adjusted ratably according to the actual amount of Standby Loan Notes issued.
The Standby Shares issued to the Standby Lenders will be in addition to the
shares of New Common Stock issued to holders of Existing Bonds, holders of
Existing Common Stock and to persons participating in the Rights Offering or
Private Placement. The manner in which shares of New Common Stock are subject to
dilution is illustrated in the Disclosure Statement.

                         MEANS FOR EXECUTION OF THE PLAN

      13.1 Substantive Consolidation: For purposes of this Plan, all the Debtors
will be treated as substantively consolidated with the Parent Company.

      13.2 Reorganized Debtors: From and after the Effective Date, each of the
Reorganized Debtors will continue in existence as a separate corporate entity,
in accordance with the law applicable in the jurisdiction under which it was
incorporated and pursuant to its charter and bylaws in effect on the Effective
Date. Each of the Reorganized Debtors will not be liquidated, and will continue
to engage in the businesses permitted by its charter and bylaws. The stock in
each Reorganized Debtor other than the Reorganized Parent Company will not be
affected by this Plan.

      13.3 Payment of Allowed Bank Group Claim: The Reorganized Parent Company
will obtain the funds necessary for the payment of the Allowed Bank Group Claim
through the combination of (i) the Credit Facility, (ii) the Rights Offering or
the Private Placement, (iii) cash on hand from the Debtors' operations, and (iv)
the Standby Loan, if necessary.

            (a) The Credit Facility. On the Effective Date, the Reorganized
      Parent Company will establish the Credit Facility with Chase, as agent for
      the Lenders, for a principal amount of up to $250 million. The Credit
      Facility will limit advances to the amount of the borrowing base, which is
      anticipated to be set initially at $210 million, $10 million of which must
      remain undrawn and available on the Effective Date. The borrowing base
      will be the loan value to be assigned to the proved reserves attributable
      to the Reorganized Parent Company's oil and gas properties. The initial
      borrowing base will be subject to Chase's review of the January 1, 2000
      reserve report to be prepared by the Parent Company and audited by an
      independent petroleum engineering firm acceptable to the Lenders. The
      initial borrowing base will be determined before the Confirmation Hearing.

            The Credit Facility will be subject to semiannual borrowing base
      redeterminations, each May 1 and November 1, and such redeterminations
      will be made in the sole discretion of the Lenders. The Reorganized Parent
      Company will deliver to the Lenders by April 1 and October 1 of each year
      a reserve report prepared as of the immediately preceding January 1 and
      July 1, respectively. The January 1 reserve report will be prepared by the
      Reorganized Parent Company and audited by an independent petroleum
      engineering firm, acceptable to Chase and the July 1 reserve report will
      be prepared internally by the Reorganized Parent Company, in a form
      acceptable to Chase. Based in part on the reserve report, the Lenders will
      redetermine the borrowing base in their sole discretion. For an increase
      in the borrowing base, consent of 100% of the Lenders will be required. To
      maintain the borrowing base, or to reduce the borrowing base, consent of
      75% of the Lenders of outstanding loans or, in the event that no loans are
      outstanding'. the Lenders holding 75% of the current commitments under the
      Credit Facility, will be required. The Reorganized Parent Company or Chase
      may request one additional borrowing base determination during any
      calendar year.


                                       10
<PAGE>

            (b) Credit Facility Interest Payments and Term. Interest on advances
      under the Credit Facility will be payable on the earlier of (i) the
      expiration of any interest period under the Credit Facility or (ii)
      quarterly, beginning with the first quarter after the Effective Date.
      Amounts outstanding under the Credit Facility will accrue interest at the
      option of the Reorganized Parent Company at (i) the Eurodollar Rate, plus
      an applicable margin, or (ii) the Base Rate, plus an applicable margin.
      All outstanding advances under the Credit Facility are due and payable in
      full three years from the Effective Date.

            (c) Security. The Credit Facility will be secured by granting first
      and prior security interests and mortgage liens in the Collateral to Chase
      for the benefit of the Lenders. The rights and responsibilities of Chase,
      the Lenders and the Debtors will be governed by the Credit Agreement and
      related documents, which will permit the Lenders to enforce their rights
      to the Collateral upon the occurrence of an "event of default" (as defined
      in the Credit Agreement).

            (d) Fees Paid in Connection with the Credit Facility. Certain fees
      for the Lenders contained in the Chase Commitment Letter were approved by
      the Bankruptcy Court at a hearing on the fees held on January 27, 2000.
      These fees include an initial due diligence fee of $200,000. If the
      Lenders fund under the Credit Facility on the Effective Date, they will be
      entitled to an additional aggregate $6.5 million of closing fees. All fees
      paid by the Parent Company in connection with the Credit Facility are
      non-refundable and are in addition to reimbursements to be paid for
      expenses incurred by Chase in connection with the preparation of the
      Credit Agreement.

            The Chase Commitment Letter provides that there are a number of
      conditions that must be met before the Lenders will be committed to fund
      the Credit Facility on the Effective Date, including: (a) agreement
      concerning definitive documents, (b) completion of economic due diligence
      and (c) approval by Chase of the Reorganized Parent Company's management
      team and capital structure. Chase and the Debtors will come to agreement
      on definitive documents in keeping with the terms of the Plan by March 1.
      2000. When Chase indicates to the Debtors by the later of March 14, 2000
      or the last business day immediately preceding the Confirmation Hearing,
      that all conditions have been met, the Lenders will be committed to fund
      on the Effective Date. If the Lenders fund on the Effective Date, they
      will be entitled to $6.5 million in closing fees.

            (e) Payment of Allowed Bank Group Claim. The Allowed Bank Group
      Claim consists of approximately $240 million of principal (plus accrued
      interest and reasonable fees and expenses). The Reorganized Parent Company
      will use approximately $200 million in advances under the Credit Facility
      toward the payment of the Allowed Bank Group Claim. The remaining amount
      of the Allowed Bank Group Claim will be paid with the proceeds of the
      Rights Offering, the Private Placement, and if necessary, the Standby
      Loan. The Allowed amount of the Bank Group Claim will be fixed and
      determined before the conclusion of the Confirmation Hearing, either by
      agreement between the Bank Group, the Debtors and the Creditors Committee,
      or as allowed by Bankruptcy Court order after objection.

    13.4 New Investment: To implement this Plan, the Reorganized Debtors wil1
raise up to $90 million of new investment in the Reorganized Parent Company by
the Rights Offering or the Private Placement, and, if applicable, the Standby
Loan. A portion of the proceeds from the Rights Offering, the Private Placement
and the Standby Loan, if applicable, will be used to pay the balance of the Bank
Group Claim.

            (a) The Rights offering or Private Placement. Under the Rights
      Offering, holders of Existing Common Stock as of the Rights Offering
      Record Date will have the right to buy additional shares of the New Common
      Stock based on the number of shares of Existing Common Stock owned as of
      the Rights Offering Record Date, for a price of $0.26 per share, up to an
      aggregate of $90 million. Holders of Existing Common Stock as of the
      Rights Offering Record Date who wish to purchase more than their allocable
      portion of the shares offered to them in the Rights Offering may do so, to
      the extent that other shareholders do not elect to participate in the
      Rights Offering. If the Rights Offering is not fully subscribed up to $90
      million by the holders of Existing Common Stock as of the Rights Offering
      Record


                                       11
<PAGE>

      Date, then the Parent Company may offer the remaining shares of New Common
      Stock to third parties pursuant to the Rights Offering.

            (b) Registration and Termination of Rights Offering; Private
      Placement. In connection with the Rights Offering, the Parent Company
      filed a registration statement with the SEC to register the Rights and to
      register the shares of New Common Stock under the Rights Offering. If the
      registration statement filed with the SEC is not declared effective by a
      date sufficiently early to give the Parent Company adequate time to
      arrange and complete the Rights Offering, the Parent Company may, in its
      sole discretion, discontinue the Rights Offering and proceed with the
      Private Placement. The Parent Company paid a filing fee of $23,760 to the
      SEC in conjunction with the filing of the registration statement and other
      associated expenses in conjunction with the printing and mailing of the
      related prospectus. If the Rights Offering is not fully subscribed up to
      $90 million by holders of Existing Common Stock as of the Rights Offering
      Record Date, then the Parent Company may offer any of the remaining shares
      to third-party investors. The Rights Offering or the Private Placement
      would be arranged by Jefferies & Company, Inc., or another investment
      banker, subject to the approval of the Bankruptcy Court. Jefferies &
      Company, Inc., or another investment banker, will be retained for the
      limited purpose of arranging the Rights Offering or the Private Placement
      and not as a general financial advisor to the Debtors.

            This Plan refers to and briefly describes, as an integral part of
      the Plan, a "Rights Offering" and a "Private Placement". This Plan does
      not and the Disclosure Statement will not constitute a solicitation of
      acceptance of rights to be distributed pursuant to the Rights Offering, an
      offer to sell (or a solicitation of an offer to buy) the rights or the
      shares of New Common Stock to be offered pursuant to the Rights Offering,
      or, if applicable, an offer to sell (or the solicitation of an offer to
      buy) the shares of New Common Stock to be offered pursuant to the Private
      Placement. The issuance of the rights pursuant to the Rights Offering and
      the offer of shares of New Common Stock pursuant to the Rights Offering
      may only be made by means of a prospectus included within a registration
      statement that has been filed with, and that has been declared effective
      by, the SEC and after compliance with any applicable state or other
      securities laws, The Parent Company has filed a registration statement
      with the SEC. Any offer of shares of New Common Stock pursuant to the
      Private Placement may only be made by means of, and on the conditions
      contained in, an offering memorandum provided by the Parent Company.
      Information about the Rights Offering and the Private Placement is
      included in the Disclosure Statement and in this Plan solely for the
      purpose of satisfying requirements of the Bankruptcy Code to provide
      information adequate to enable the holders of claims and interests to make
      an informed decision about the Plan.

            (c) The Standby Loan. The Standby Loan is to be made pursuant to a
      senior subordinated note facility under which the Reorganized Debtors will
      issue, and the Standby Lenders will purchase, an amount of senior
      subordinated notes to be determined by the Reorganized Debtors. This
      amount will be a maximum of $70 million given the current level of
      commitment under the Standby Loan and a maximum of $90 million if more
      Standby Loan commitments are obtained and made available before the
      conclusion of the Confirmation Hearing, or the Effective Date, if the
      Debtors choose to extend the Rights Offering to that date. The rights and
      responsibilities of the Standby Lenders and the Debtors will be governed
      by the Standby Loan Agreement.

            (d) Terms of the Standby Loan. Debt under the Standby Loan Agreement
      will be evidenced by the Standby Loan Notes, maturing seven years after
      the Effective Date and bearing interest at a minimum annual rate of 15%
      and payable in cash semiannually. After the first anniversary of the
      Effective Date, additional semiannual interest will be payable in an
      amount equal to 1/2% for every $0.25 that the Actual Price exceeds $15 per
      barrel of oil equivalent during the applicable semiannual interest period,
      up to a maximum of 10% additional interest per year. Additionally, upon an
      event of default occurring under the Standby Loan, interest will be
      payable in cash, unless otherwise required to be paid-in-kind, at a rate
      equal to 2% per year over the applicable interest rate. The Actual Price
      will be calculated over a six-month measurement period ending on the date
      two months before the applicable


                                       12
<PAGE>

      interest payment date. Interest on the Standby Loan may be paid-in-kind
      subject to the requirements of the Credit Agreement.

            (e)Payment of Indebtedness under the Standby Loan. Payment of the
      Standby Loan Notes will be subordinate to payments in full in cash of all
      obligations arising in connection with the Credit Facility. Subject to a
      final agreement between the Standby Lenders and Chase, after the initial
      12-month period, cash interest payments may be made only to the extent by
      which earnings before income tax, depreciation and amortization expense
      ("EBITDAX") on a trailing four-quarter basis exceed $65 million. The
      Credit Agreement may also prohibit the Reorganized Parent Company from
      making any cash interest payments on the Standby Loan indebtedness if the
      outstanding indebtedness under both the Credit Facility and the Standby
      Loan, exceeds 3.75 times the EBITDAX for the trailing four quarters. The
      Reorganized Parent Company may prepay the Standby Loan Notes at the face
      amount, in whole or in part, in minimum denominations of $1,000,000, plus
      either (i) a standard make-whole payment with a discount rate of 300 basis
      points over the Treasury Rate for the first four years, or (ii) beginning
      in the fifth year, a premium equal to one-half the 15% base interest rate,
      declining annually and ratably to par. The Standby Loan Notes may only be
      paid if either (i) all obligations under the Credit Facility have been
      paid in full in cash or (ii) if the Lenders of 75% of the outstanding
      loans or, if none are outstanding, the Lenders holding 75% of the current
      loan commitments under the Credit Facility consent to the payment.

            (f) Standby Shares. If the Standby Loan Notes are issued, the
      Standby Lenders will receive the Standby Shares. If $70 million in Standby
      Loan Notes are issued, the Standby Lenders will receive 14% of the fully
      diluted New Common Stock. The amount of Standby Shares issued will be
      adjusted ratably according to the actual principal amount of Standby Loan
      Notes issued. The Standby Shares issued to the Standby Lenders will be in
      addition to the shares of New Common Stock issued to holders of the
      Existing Bonds, holders of Existing Common Stock and persons participating
      in the Rights Offering or Private Placement. See the Disclosure Statement
      for an illustration of the dilution of the New Common Stock.

            (g) Fees Paid in Connection with the Standby Loan. Certain fees for
      the Standby Lenders contained in the Standby Lender Fee Letter were
      approved by the Bankruptcy Court in a hearing on the fees held on January
      27, 2000. This includes (I) a due diligence fee of $200,000 payable
      immediately and (2) break up a fee of $1.0 million (the "Break Up Fee"),
      to be paid if the Standby Lenders give the Debtors written notice that all
      conditions to closing have been met and if a plan of reorganization is
      subsequently confirmed and consummated that does not use the Standby Loan.
      If, after receiving a letter from the Standby Lenders that all conditions
      have been met, the Debtors subsequently obtain confirmation of a plan of
      reorganization without an alternative financing proposal, the Debtors will
      owe the Standby Lenders a closing fee in an amount equal to the greater of
      $1.0 million or 3 1/2% of the aggregate principal amount of the Standby
      Loan Notes purchased (the "Closing Fee"). The obligation of the
      Reorganized Debtors to pay the Break Up Fee or Closing Fee, will be an
      administrative expense claim having priority over all administrative
      expenses in accordance with section 364(c)(l) of the Bankruptcy Code. The
      Debtors will pay either the Closing Fee or the Break Up Fee, but not both.

      The Standby Lender Fee Letter provides that there are only two essential
kinds of conditions which must be met before the Standby Lenders will be
committed to fund the Standby Loan on the Effective Date: (1) agreement to
definitive documents and (2) completion of economic due diligence. The Standby
Lenders and the Debtors will come to agreement on definitive documents in
keeping with the terms of the Plan and satisfactory to both of them. When the
Standby Lenders indicate by letter to the Debtors on the later of March 14,
2000, or the last business day immediately prior to the Confirmation Hearing,
that they have completed their due diligence and that all conditions to closing
have been met except entry of an order confirming the Plan, then (1) the Standby
Lenders will be committed to fund on the Effective Date and (2) the Standby
Lenders will be entitled to a minimum fee of $1.0 million, either as a Closing
Fee or a Break Up Fee. If the Standby Lenders do not notify the Debtors in
writing by the later of March 14, 2000, or the last business day immediately
preceding the Confirmation Hearing, that all conditions have been met, then they
will be entitled to their reasonable fees and expenses in


                                       13
<PAGE>

      connection with the Standby Loan, but they will not be entitled to the
      Break Up Fee. If the Standby Lenders fund the Standby Loan on the
      Effective Date, they will be entitled to the Closing Fee, and will not be
      entitled to the Break Up Fee.

            ~ (h) Other Sources of Financing. Contemporaneous with the filing of
      this Plan, the Debtors have supported Bankruptcy Court approval of
      procedures whereby other parties interested in providing the Standby Loan
      on more favorable terms to the Reorganized Debtors may offer binding
      commitments by the end of the Disclosure Statement hearing.

      13.5 Revesting of Assets: Except as otherwise provided in this Plan, the
property and assets of the Debtors' bankruptcy estate under section 541 of the
Bankruptcy Code, including all Claims listed in Articles XVI and XVII hereof
will revest in the Reorganized Debtors on the Effective Date free and clear of
all Claims and Equity Interests, but subject to the obligations of the
Reorganized Debtors as set forth in this Plan. Commencing on the Effective Date,
the Reorganized Debtors may deal with their assets and property and conduct
their businesses, without any supervision by, or permission from, the Bankruptcy
Court or the office of the United States Trustee and free of any restriction
imposed on the Debtors by the Bankruptcy Code or by the Bankruptcy Court during
the Chapter 11 Case.

      13.6 New Common Stock: The provisions of the New Common Stock to be issued
pursuant to the Plan are summarized as follows:

            (a) Authorization. The Reorganized Parent Company will be authorized
      to issue the number of shares of New Common Stock set forth in the
      Disclosure Statement.

            (b) Par Value. The New Common Stock has a par value of $0.01 per
      share.

            (c) Rights. The New Common Stock has such rights with respect to
      dividends, liquidation, voting and other matters as set forth in the
      amended and restated articles of incorporation of the Reorganized Parent
      Company and as provided under applicable law.

            (d) Dilution. The New Common Stock issued to holders of Existing
      Common Stock as of the Voting Record Date and holders of Existing Bonds is
      subject to dilution by the Rights Offering, the Private Placement and the
      Standby Shares, if necessary. The New Common Stock issued to persons
      participating in the Rights Offering or the Private Placement will not be
      subject to dilution by the Standby Shares. See the Disclosure Statement
      for an illustration of the dilution of the New Common Stock.

      13.7 Directors and Officers: Debtor's current directors and officers are
listed in the Disclosure Statement. In accordance with section 1125(a) of the
Bankruptcy Code, these will be the officers and directors on the Effective Date
and immediately thereafter, however, in keeping with the provisions of this
paragraph, as soon as practicable after the Effective Date the new board of
directors of the Reorganized Debtors will convene a meeting. Four members of the
post-Effective Date board of directors will be selected by the Principal
Bondholders. One member of the board of directors will be selected by the
post-Effective Date board of directors from the Debtors' post-Effective Date
management. Two members of the board of directors will be selected by the
entities whose new investment funding is used on the Effective Date (whether
under the Standby Loan or some alternative source of funding) based upon their
relative contributions of capital. Accordingly, certain parties have rights
under the Plan to designate new directors. Those parties have not yet made those
designations. Any such designations will be made before the commencement of the
Confirmation Hearing and will be disclosed at the Confirmation Hearing. Any
changes in officers made before the completion of the Confirmation Hearing will
be disclosed during the Confirmation Hearing. Any further changes in officers
will be made after the Effective Date by the board of directors of the
Reorganized Parent Company. Upon approval of the Plan, a retention bonus plan,
under which certain key employees are provided with additional incentives to
continue their employment with the Parent Company as it pursues a
reorganization, will be implemented as described in the Disclosure Statement.

      13.8 Amended and Restated Articles of Incorporation: The amended and
restated articles of incorporation of the Reorganized Parent Company and the
charters of the other Reorganized Debtors, as amended


                                       14
<PAGE>

pursuant to this Plan, will go into effect on the Effective Date and will
satisfy the provisions of this Plan and section 1123(a) (6) of the Bankruptcy
Code.

      13.9 Implementing Documents. To implement this Plan, several documents
will be signed and delivered or otherwise made effective, including the
following documents:

      o     Promissory Note to be issued to holders of Allowed Priority Tax
            Claims

      o     Credit Agreement

      o     Standby Loan Agreement

      o     Amended Employment Agreements

      o     Amended and restated articles of incorporation of Coho Energy, Inc.

      o     Amended and restated bylaws of Coho Energy, Inc.

      o     Registration rights agreement

      o     Shareholders' agreement

Forms of these documents will be filed with the Bankruptcy Court by March 1,
2000. Thereafter, the Debtors will provide a copy of the form of any of these
documents to any party in interest who requests it in writing. Written requests
should be sent to the Parent Company at 14785 Preston Road, Suite 860, Dallas,
Texas 75240, Attention: Ms. Anne Marie O'Gorman.


                                   ARTICLE XIV

                    EXECUTORY CONTRACTS AND UNEXPIRED LEASES

      14.1 Assumption of Executory Contracts and Unexpired Leases: As of the
Effective Date, all executory contracts and unexpired leases of the Debtors (as
set forth in the Debtors' Schedules filed by the Debtors and as specifically
referenced in the Disclosure Statement) other than the Rejected Agreements are
assumed by the Debtors in accordance with section 365 of the Bankruptcy Code.
The Debtors and the Creditors Committee will agree by March 1, 2000 on an
amended schedule of executory contracts and unexpired leases which will be
assumed pursuant to this Plan. The Debtors believe they are current with their
obligations under all executory contracts and unexpired leases and, therefore,
the assumption of same will not result in the payment of any cure amounts which
might otherwise be due and payable. Any rights of non-Debtor parties to
executory contracts and unexpired leases to pursue claims for payment of cure
amounts are preserved. In the event of a dispute regarding the amount or timing
of any cure payments, the ability of the Reorganized Debtors to provide adequate
assurance of future performance or any other matter pertaining to assumption,
the dispute will be resolved by the Bankruptcy Court in connection with the
Confirmation Hearing and the Reorganized Debtors will make such cure payments,
if any, or provide such assurance as may be required by the order resolving such
dispute on the terms and conditions of such order. Employment agreements for
certain key employees will be amended and the Amended Employment Agreements will
be filed with the Bankruptcy Court by March 1, 2000. The Amended Employment
Agreements will provide, among other things, that confirmation and consummation
of this Plan and related events do not constitute a change of control under
these contracts. These Amended Employment Agreements will be assumed under the
Plan. If an employee is requested to execute and deliver an Amended Employment
Agreement by the Creditors Committee, and refused to do so, that employee's
existing employment agreement will he added to the list of contracts to be
rejected and rejected pursuant to the Plan on the Effective Date.

      14.2 Indemnification Obligations and Insurance Policies: The obligations
of the Debtors pursuant to their certificates of incorporation, bylaws or
applicable state law to indemnify the directors and officers who served as
directors and officers of the Debtors before and after the Petition Date against
any obligations based on conduct or transactions that occurred while they were
officers and directors before or after the Petition Date will continue after the
Confirmation Date. On the Effective Date the Reorganized Parent Company will


                                       15
<PAGE>

purchase (i) a new directors and officers insurance policy covering the new
post-Effective Date directors and officers and (ii) a three-year tail insurance
policy on existing director and officer policies, if it can be purchased for no
more than $300,000, or take such other action concerning the purchase of tail
insurance as the board of directors of the Reorganized Parent Company believes
is reasonable.

      14.3 Rejection of Certain Executory Contracts and Unexpired Leases: The
Plan Confirmation Order will operate as an order of rejection under section 365
of the Bankruptcy Code with respect to each of the Rejected Agreements.

      14.4 Treatment of the Existing Bond Indenture: As of the Effective Date,
except to the extent provided otherwise in the Plan, all notes held by holders
of Bond Claims, and all agreements, instruments and other documents evidencing
the Existing Bonds and the rights of the holders of Bond Claims, will be
automatically canceled, extinguished and are void (all without further action by
any person); all obligations of any person under these instruments and
agreements will be fully and finally satisfied and released; and the obligations
of the Debtors under these instruments and agreements will be discharged. On the
Effective Date, except to the extent provided otherwise in the Plan, any
indenture relating to any of the foregoing, including, without limitation, the
Existing Indenture, will be canceled, and the obligations of the Debtors
thereunder, except for the obligation to indemnify the Indenture Trustee will be
discharged; however, the Existing Indenture and other agreements that govern the
rights of a holder of a claim that is administered by the Indenture Trustee, an
agent or servicer will continue in effect solely for the purposes of (i)
allowing the Indenture Trustee, agent or servicer to take any action necessary
to effect the Plan, including making distributions on account of the holders of
Bond Claims under the Plan and (ii) permitting the Indenture Trustee, agent or
servicer to maintain any rights or liens it may have for reasonable fees, costs
and expenses under the Exiting Indenture. Upon payment in full of the reasonable
fees and expenses of the Indenture Trustee, the rights of the Indenture Trustee
will terminate.

      14.5 Claims Based on Rejection of Executory Contracts and Unexpired
Leases: All proofs of claim with respect to Claims arising from the rejection of
an executory contract or unexpired lease will be filed with the Bankruptcy Court
within 30 days after the earlier of (a) the date of entry of an order of the
Bankruptcy Court approving the rejection, or (b) the Effective Date. Any Claims
not filed within such times will be forever barred from assertion against the
Debtors, their estate or their property.

                                   ARTICLE XV

              EFFECT OF REJECTION BY ONE OR MORE CLASSES OF CLAIMS

      15.1 Impaired Classes to Vote: Each impaired class of Claims and Equity
Interests will be entitled to vote separately to accept or reject the Plan. A
holder of a Disputed Claim that has not been temporarily allowed for purposes of
voting on the Plan may vote the Disputed Claim in an amount equal to the
portion, if any, of the Claim shown as fixed, liquidated and undisputed in the
Debtors' Schedules.

      15.2 Acceptance by Class of Creditors: A class will have accepted the Plan
if the Plan is accepted by at least two-thirds in amount and more than one-half
in number of the Allowed Claims or Equity Interests of the class actually voting
that have accepted or rejected the Plan.

      15.3 Cramdown: If any impaired class will fail to accept this Plan in
accordance with section 1129(a) of the Bankruptcy Code, the Debtors reserve the
right to request the Bankruptcy Court to confirm the Plan in accordance with the
provisions of section 1129(b) of the Bankruptcy Code.

                                  ARTICLE XVI

             PROVISIONS FOR RESOLUTION AND TREATMENT OF PREFERENCES,
                   FRAUDULENT CONVEYANCES, AND DISPUTED CLAIMS

      16.1 Preferences and Fraudulent Conveyances: The Reorganized Debtors will
be the only parties authorized to object to Claims and to pursue actions to
recover preferences and fraudulent conveyances or any other transaction voidable
under Chapter 5 of the Bankruptcy Code. Unless the Reorganized Debtors consent,
or unless otherwise ordered by the Bankruptcy Court, no other party will have
the right or obligation to pursue such actions.

      16.2 Objections to Claims: The Debtors will have the sole authority to
object and contest the allowance of any Claims filed with the Bankruptcy Court
within 90 days after the Effective Date. Claims listed as disputed, contingent
or unliquidated on the Debtors' Schedules are considered contested Claims,
except Claims otherwise treated by the Plan or previously allowed or disallowed
by Final Order of the Bankruptcy Court.

      16.3 Disputed Claims Reserve: Debtors will hold in trust the Distributions
for Disputed Claims (pending a determination of the Disputed Claims) for the
benefit of holders of Disputed Claims. At such time as a Disputed Claim becomes
an Allowed Claim, that will be deemed the Effective Date for purposes of such
Claim and the Distributions allowed for such Allowed Claims will be released
from the Disputed Claims Reserve and delivered to the holder of such Allowed
Claim. If a Disputed Claim is disallowed, the Distributions provided for the
Claim will be released to the Reorganized Debtors for use in their business
operations.

      16.4 Unclaimed Distributions: On the second, third and fourth
anniversaries of the Effective Date, the Reorganized Debtors will publish the
names of holders of unclaimed Claims and Equity Interests. In the event any
Distributions under the Plan remain unclaimed as of five (5) years after the
Effective Date such Distributions will be released for the Reorganized Debtors
use in their ordinary business operations.

                                  ARTICLE XVII

              PROVISIONS FOR RETENTION, ENFORCEMENT, SETTLEMENT, OR
                  ADJUSTMENT OF CLAIMS BELONGING TO THE ESTATE

      17.1 Causes of Action: All claims recoverable under Chapter 5 of the
Bankruptcy Code, including, but not limited to, all claims assertable under
sections 544, 546, 547, 548 and 550 of the Bankruptcy Code, and all claims owned
by the Debtors pursuant to section 541 of the Bankruptcy Code or similar state
law, including all claims against third parties on account of any indebtedness,
and all other claims owed to or in favor of the Debtors to the extent not
specifically compromised and released pursuant to this Plan or an agreement
referred to or incorporated herein, will be preserved and retained for
enforcement by the Reorganized Debtors after the Effective Date.

      17.2 Legally Binding Effect; Discharge of Claims and Equity Interests: The
provisions of this Plan will (a) bind all Creditors and Equity Interest holders,
whether or not they accept this Plan, and (b) discharge the Debtors from all
debts that arose before the Petition Date. In addition, the distributions of
Cash and securities provided for under this Plan will be in exchange for and in
complete satisfaction, discharge and release of all Claims against and Equity
Interests in the Debtors or any of their assets or properties, including any
Claim or Equity Interest accruing after the Petition Date and before the
Effective Date. On and after the Effective Date, all holders of impaired Claims
and Equity Interests will be precluded from asserting any Claim against the
Reorganized Debtors or their assets or properties based on any transaction or
other activity of any kind that occurred before the Petition Date. The
Distributions provided for Creditors and Equity Interest holders will not be
subject to any Claim by another Creditor or Equity Interest holder by reason of
an assertion of a contractual right of subordination.

                                 ARTICLE XVIII

                    CONDITIONS PRECEDENT TO CONFIRMATION AND
                            CONSUMMATION OF THE PLAN

      18.1 Conditions to Confirmation: The Bankruptcy Court will not enter the
Confirmation Order unless and until each of the following conditions has been
satisfied or duly waived (if waivable) pursuant to Section 18.3 below.

            (a) The documents implementing the Plan listed in Section 13.9 above
      and the terms and conditions embodied therein will be acceptable in form
      and substance to the Debtors, the Creditors Committee, Chase, the Standby
      Lenders and Bank Group; provided that no Creditor or committee will have
      standing to object to the form of a document that has no material impact
      on them.

            (b) Entry of a Confirmation Order, acceptable in form and substance
      to the Debtors and the Creditors Committee, which will, among other
      things, make findings that particular sections of 1129 have been met,
      including, without limitation, (i) that the Debtors, the Plan Participants
      and each of their Representatives have proposed and obtained confirmation
      of the Plan in good faith; (ii) that the Plan is in the best interest of
      Creditors and (iii) that the Plan is fair and equitable to holders of
      Claims and Equity Interests.

      18.2 Conditions to Effective Date: The Plan will not be consummated and
the Effective Date will not occur unless and until each of the following
conditions has been satisfied or duly waived (if waivable) pursuant to Section
18.3 below:

            (a) The Confirmation Order shall have been entered by the Bankruptcy
      Court in a form satisfactory to the Debtors, the Creditors Committee,
      Chase, the Standby Lenders and the Bank Group.

            (b) The Confirmation Order will authorize and direct the Debtors,
      the Reorganized Debtors and their subsidiaries to take all actions
      necessary or appropriate to enter into, implement and consummate the
      contracts, instruments, releases, leases, indentures and other agreements
      or documents created in connection with the Plan, including those actions
      contemplated by the provisions of the Plan set forth in Section 18.1
      above.

            (c) The Credit Facility, the Rights Offering, the Private Placement
      and, if applicable, the Standby Loan, shall all close prior to or on the
      Effective Date so that funds are available to pay the Allowed Bank Group
      Claim in full on or prior to the Effective Date.

            (d) The Effective Date will have occurred on or before March 31,
      2000.

      18.3 Waiver of Conditions: The conditions to Confirmation and the

consent of the Creditors Committee, at any time, without notice.

      18.4 Effect of Non-occurrence of Conditions to Effective Date: Each of the
conditions to consummation and the Effective Date must be satisfied or duly
waived, as provided above, within 90 days after the Confirmation Date. If each
condition to the Effective Date has not been satisfied or duly waived, pursuant
to Section 18.3 above, within 90 days after the Confirmation Date, then upon
motion by any party in interest made before the time that each condition has
been satisfied or duly waived and upon notice to such parties in interest as the
Bankruptcy Court may direct, the Confirmation Order will be vacated by the
Bankruptcy Court; provided, however, that, notwithstanding the filing of such
motion, the Confirmation Order may not be vacated if each of the conditions to
the Effective Date is either satisfied or duly waived before the Bankruptcy
Court enters an order granting the motion. If the Confirmation Order is vacated
pursuant to this Section 18.4, the Plan will be deemed null and void, including
the discharge of Claims and termination of Equity Interests pursuant to section
1141 of the Bankruptcy Code; and the assumptions, assumptions and assignments or
rejections of executory contracts and unexpired leases pursuant to Section 14.1
above, and nothing contained in the Plan will (1) constitute a waiver or release
of any Claims by or against, or any Equity Interests in the Debtors or (2)
prejudice in any manner the rights of the Debtors.

                                  ARTICLE XIX

                            RETENTION OF JURISDICTION

      19.1 Jurisdiction: Until this Chapter 11 Case is closed, the Bankruptcy
Court will retain such ~ jurisdiction as is legally permissible, including that
necessary to ensure that the purpose and intent of this Plan are carried out and
to hear and determine all Claims set forth in Articles V through XI above that
could have been brought before the entry of the Confirmation Order. The
Bankruptcy Court will retain jurisdiction to hear and determine all Claims
against the Debtors and to enforce all causes of action that may exist on behalf
of the Debtors. Nothing contained in this Plan will prevent the Reorganized
Debtors from taking such action as may be necessary in the enforcement of any
cause of action that may exist on behalf of the Debtors and that may not have
been enforced or prosecuted by the Debtors.

      19.2 Examination of Claims: Following the Confirmation Date, the
Bankruptcy Court will further retain jurisdiction to decide disputes concerning
the classification and allowance of the Claim of any Creditor and the
re-examination of Claims that have been allowed for the purposes of voting, and
the determination of such objections as may be filed to Creditors' Claims. The
failure by the Debtors to object to, or to examine, any Claims for the purposes
of voting will not be deemed a waiver of their right to object to, or to
re-examine, the Claim in whole or in part.

      19.3 Determination of Disputes: The Bankruptcy Court will retain
jurisdiction after the Confirmation Date to determine all questions and disputes
regarding title to the assets of the Debtors' estate, disputes concerning the
allowance of Claims, and determination of all causes of action, controversies,
disputes, or conflicts, whether or not subject to any pending action, as of the
Confirmation Date, for the Debtors to recover assets pursuant to the provisions
of the Bankruptcy Code.

      19.4 Additional Purposes: The Bankruptcy Court will retain jurisdiction
for the following additional purposes after the Effective Date:

            (a) to modify this Plan after confirmation pursuant to the
      Bankruptcy Rules and the Bankruptcy Code;

            (b) to assure the performance by the Reorganized Debtors of their
      obligations to make Distributions under this Plan and with respect to the
      New Common Stock to be issued;

            (c) to enforce and interpret the terms and conditions of this Plan;

            (d) to adjudicate matters arising in these bankruptcy cases,
      including matters relating to the formulation and consummation of this
      Plan;

            (e) to enter such orders, including injunctions, as are necessary to
      enforce the title, rights, and powers of the Reorganized Debtor and to
      impose such limitations, restrictions, terms and conditions on such title,
      rights, and powers as this Bankruptcy Court may deem necessary;

            (f) to enter an order terminating this Chapter 11 Case;

            (g) to correct any defect, cure any omission, or reconcile any
      inconsistency in this Plan or the order of confirmation as may be
      necessary to carry out the purposes and intent of this Plan;

            (h) to allow applications for fees and expenses pursuant to section
      503(b) of the Bankruptcy Codes: and

            (i) to decide issues concerning federal tax reporting and
      withholding which arise in connection with the confirmation or
      consummation of this Plan.

                               DEFAULT UNDER PLAN

      20.1 Asserting Default: If the Debtors default under the provisions of
this Plan (as opposed to default under the documentation executed in
implementing the terms of the Plan, which documents will provide independent
bases for relief), any Creditor or party in interest desiring to assert a
default will provide the Debtors with written notice of the alleged default.

      20.2 Curing Default: The Debtors will have 20 days from receipt of the
written notice in which to cure an alleged default under this Plan, including
any default under any Related Document. The notice should be delivered by United
States certified mail, postage prepaid, return receipt requested addressed to
the president of the Debtors at the following address:

                      Coho Energy, Inc.
                      Attention: President
                      14785 Preston Road, Suite 860
                      Dallas, Texas 75240

            and to counsel for the Debtors at the following address:

                      Fulbright & Jaworski LLP
                      Attention: Michael W. Anglin
                      2200 Ross Avenue, Suite 2800
                      Dallas, Texas 75201

            and to counsel for the Creditors Committee at the following address:

                      Munger, Tolles & Olson
                      Attention: Thomas B. Walper

                      35th Floor
                      Los Angeles, California 90071

If the default is not cured, any Creditor or party in interest may thereafter
file with the Bankruptcy Court and serve upon counsel for the Debtor a motion to
compel compliance with the applicable provision of the Plan. The Bankruptcy
Court, upon finding a material default, will issue such orders compelling
compliance with the pertinent provisions of the Plan.

                                   ARTICLE XXI

                            MISCELLANEOUS PROVISIONS

the Debtor's Chapter 11 Case will be terminated except to the extent necessary
to participate in any appeals.

      21.2 Compliance with Tax Requirements: In connection with this Plan, the
Debtors will comply with all withholding and reporting requirements imposed by
federal, state, and local taxing authorities, and Distributions will be subject
to such withholding and reporting requirements.

      21.3 Amendment of the Plan: This Plan may be amended by the Debtors before
or after the Effective Date as provided in section 1127 of the Bankruptcy Code.

      21.4 Revocation of Plan: The Debtors reserve the right to revoke and
withdraw this Plan at any time before the Confirmation Date.

      21.5 Effect of Withdrawal or Revocation: If both the Debtors and the
Creditors Committee revoke or withdraw this Plan before the Confirmation Date,
or if the Confirmation Date or the Effective Date does not


                                       20
<PAGE>

occur, then this Plan will be null and void. In such event, nothing contained
herein will be deemed to constitute a waiver or release of any Claims by or
against the Debtors or any other person, or to prejudice in any manner the
rights of the Debtors or any person in any further proceedings involving the
Debtors. The withdrawal of either the Debtors or the Creditors Committee as a
proponent of this Plan will not result in the withdrawal or revocation of this
Plan and, in such event, the non-withdrawing party may proceed with its efforts
to confirm this Plan.

      21.6 Due Authorization By Creditors: Each and every Creditor who elects to
participate in the Distributions provided for herein warrants that it is
authorized to accept in consideration of the Claim against the Debtors the
Distributions provided for in this Plan and that there are no outstanding
commitments, agreements, or understandings, express or implied, that may or can
in any way defeat or modify the rights conveyed or obligations undertaken by it
under this Plan.

      21.7 Implementation: The Debtors will be authorized to take all necessary
steps, and perform all necessary acts, to consummate the terms and conditions of
the Plan.

            (a) The Plan Participants will neither have nor incur any liability
      to any entity for any act taken or omitted to be taken in connection with
      or related to the formulation, preparation, dissemination, implementation,
      confirmation or consummation of the Plan, the Disclosure Statement, the
      Confirmation Order or any contract, instrument, release or other agreement
      or document created or entered into, or any other act taken or omitted to
      be taken in connection with the Plan, the Disclosure Statement or the
      Confirmation Order, including solicitation of acceptances of the Plan;
      provided, however, that the provisions of this Section 21.9(a) shall have
      no effect on the liability of any Plan Participant that would otherwise
      result from any such act or omission to the extent that such act or
      omission is determined in a Final Order to have constituted gross
      negligence or willful misconduct.

            (b) On and after the Effective Date, the Reorganized Parent Company
      will indemnify each Plan Participant, hold each Plan Participant harmless
      from, and reimburse each Plan Participant for, any and all losses, costs,
      expenses (including attorneys' fees and expenses), liabilities and damages
      sustained by a Plan Participant arising from any liability described in
      this Section 21.9.

Notes will be held at 10:00 a.m., local time, on March 31, 2000, or such other
time and date as the Company and you shall agree (the "Closing Date"), at the

2. REPRESENTATIONS AND WARRANTIES OF THE OBLIGORS.

      To induce you to enter into this Agreement and to purchase and pay for the
Purchased Securities to be delivered to you at the Closing, the Obligors
represent and warrant as set forth below (except for Section 2.8, which the
Company alone represents and warrants).

      2.1 Nature of Business. The representations and warranties of the Company
set forth in the Credit Facility are true and correct in all material respects
as if they were made by the Company to the Purchasers hereunder as of the
Closing Date.

      2.2 Sale is Legal and Authorized; Obligations are Enforceable.

            (a) Sale of Purchased Securities is Legal and Authorized. Based in
part on the representations and warranties in Section 3 hereof, each of the
issuance, sale and delivery of the Notes by the Issuers, the execution and
delivery by each Obligor and each Subsidiary of such Obligor of the Standby Debt
Documents to which it is a party, and compliance by each Obligor and each
Subsidiary of such Obligor with all of the provisions of the Standby Debt
Documents to which it is a party:

                  (i) is within the powers of such Obligor and each of such
      Subsidiaries; and

                  (ii) is legal and does not conflict with, result in any breach
      of any of the provisions of, constitute a default under, or result in the
      creation of any Lien upon any Property of any Obligor or any such
      Subsidiary under the provisions of:

                  (A)any Organic Document of, or any agreement or instrument to
            which, such Obligor or such Subsidiary is a party or by which such
            Obligor or such Subsidiary or any of its respective Property may be
            bound;

                  (B) any order, judgment, decree, or ruling of any court,
            arbitrator or Governmental Authority applicable to such Obligor or
            such Subsidiary or any of its respective Property; or

                  (C) any statute or other rule or regulation of any
            Governmental Authority applicable to such Obligor or such Subsidiary
            or any of its respective Property;

      except for such conflicts, breaches, defaults or Liens which in the
      aggregate could not be reasonably expected to have a Material Adverse
      Effect.

Subsidiary is a party has been executed and delivered by one or more duly
authorized officers of such Obligor or such Subsidiary, and constitutes a legal,
valid and binding obligation of such Obligor or such Subsidiary, enforceable in
accordance with its terms, except that, in each case, the enforceability thereof
may be:

                  (i) limited by applicable bankruptcy, reorganization,
      arrangement, insolvency, moratorium, or other similar laws affecting the
      enforceability of creditors' rights generally; and

relationship between any Obligor or any such Subsidiary and any other Person,
nor any circumstance in connection with the offer, issuance, sale or delivery of
the Notes, the execution and delivery of any Standby Debt Document, nor the
performance of the obligations of any Obligor or any Subsidiary thereunder, is
such as to require a consent, approval or authorization of, or pre-filing,
registration or qualification with, any Governmental Authority on the part of
any Obligor or such Subsidiary as a condition thereto, except for confirmation
of the Plan of Reorganization by the Bankruptcy Court.

            (b) Each of the issuance and sale of the Notes, the incurrence of
the Indebtedness evidenced by the Standby Debt Documents and the other
obligations represented thereby, the execution and delivery of the Standby Debt

delivery of the Standby Debt Documents and the issuance and sale of the Notes in
connection therewith, would constitute a Default or an Event of Default.

      2.5 Private Offering of Purchased Securities.

      No Obligor nor any Person acting on behalf of any Obligor has offered any
of the Notes or the Additional Shares for sale to, or solicited offers to buy
any thereof from, or otherwise approached or negotiated with respect thereto
with, any prospective purchaser, other than twenty-nine or fewer institutional
"accredited investors" (as defined in Regulation D under the Securities Act)
(including you), each of whom was offered all or a portion of the Notes and the
Additional Shares at private sale for investment.

      2.6 Use of Proceeds.

            (a) Use of Proceeds. The Obligors shall apply the proceeds from the
sale of the Purchased Securities as contemplated by the Plan of Reorganization
and the Note Agreement.

            (b) Margin Regulations. None of the transactions contemplated in any
of the Standby Debt Documents (including, without limitation, the use of the
proceeds from the sale of the Purchased Securities) violates or will result in a
violation of Section 7 of the Exchange Act, or any regulation issued pursuant
thereto, including, without limitation, Regulation T, Regulation U or Regulation
X of the Board of Governors of the Federal Reserve System, 12 C.F.R., Chapter
11.

            (c) Absence of Foreign or Enemy Status. Neither the sale of the
Purchased Securities nor the use of proceeds from the sale thereof will result
in a violation of any of the foreign assets control regulations of the United
States Treasury Department (31 CFR, Subtitle B, Chapter V, as amended), or any
ruling issued thereunder or any enabling legislation or Presidential Executive
Order in connection therewith.

      2.7 Credit Facility.

Obligors will have duly performed all of their obligations in connection with
the Credit Facility to be performed at or prior to the closing thereunder, the
Loan Documents (as such term is defined in the Credit Facility) thereunder have
all been duly executed and delivered and are in full force and effect, and no
Default or Event of Default (as such terms are defined in the Credit Facility)
has occurred thereunder. The Company has provided to you or your agents true,
correct and complete copies of each of the agreements and instruments executed
and delivered in connection with the Credit Facility, and there is no other
material agreement or understanding between or among any Obligor and any of the
holders of any Senior Indebtedness that has not been so provided to you.


                                      -6-

      2.8 Capitalization.

            (a) Capitalization. All equity interests in the Company (including
Capital Stock), Rights and other Securities (including all shares of the New
Common Stock) have been duly authorized and validly issued and are fully paid,
non-assessable, free and clear of any Lien.

            (b) Restrictive Agreements. Other than the Registration Rights
Agreement, to the best knowledge of the Responsible Officers of the Obligors,
there is no agreement or understanding between or among the holders of equity
interests in the Company or any Rights in respect of the foregoing, in each case
regarding any of the equity interests, Rights or the holders thereof.

      2.9 No Placement Fees.

      No investment banker, placement agent, broker or other intermediary was
employed by any Obligor or its Affiliates in connection with the issuance of the
Purchased Securities or the incurrence or placement of the Indebtedness under
the Credit Facility, and, therefore, no fees or other consideration have been
paid or are payable to any such Persons in connection with such transaction.

      2.10 Confirmation Order.

      A Confirmation Order has been duly entered by the Bankruptcy Court, is in
full force and effect and has not been vacated or otherwise modified since its
original entry.

4. CLOSING CONDITIONS.

      Your obligations under this Agreement, including, without limitation, the
obligation to purchase and pay for the Purchased Securities to be delivered to

your election, of all such obligations.

      You shall have received from Fulbright & Jaworski, L.L.P., counsel to the
Obligors, a closing opinion, dated as of the Closing Date, and substantially in

warranties contained in Section 2 shall be true in all material respects on the

Obligor shall have performed and complied with all agreements and conditions
contained herein and in the other Standby Debt Documents that are required to be
performed or complied with by such Obligor on or prior to the Closing Date, and

unless such performance or compliance has been waived by you in accordance with
the terms hereof.

      4.3 Officers' Certificates.

            Board of Directors determines in its reasonable good faith judgment
            that there is a valid business purpose for such suspension and
            provides notice to the Holders that such determination was made by
            the Company's Board; provided, however, that notwithstanding the
                                 --------  -------
            foregoing, if the Company shall furnish to the Holders a certificate
            signed by the President of the Company stating that in the good
            faith reasonable judgment of the Board of Directors of the Company

            consummated or, if earlier, the date upon which any such
            interference with such existing or anticipated acquisition or
            financing would no longer exist, or (iii) forty-five (45) days after
            the date of such written notice to the Holders; provided, however,
                                                            --------  -------
            that the Company may not utilize this suspension right more than
            once in any twelve-month period.

            3. Demand Registration.
               -------------------

                  (a) At any time after March 31, 2001, the Holder or Holders of
            at least ten (10%) percent of all Registrable Stock then outstanding
            (the "Initiating Holders") may, subject to the provisions of Section
            3(b) hereof, by notice in writing to the Company request the Company
            to register under the Securities Act all or any portion of shares of
            Registrable Stock held by such Initiating Holder or Holders for sale
            in the manner specified in such notice. Notwithstanding anything to
            the contrary contained herein, the Company shall not be required to
            seek to cause a Registration Statement to become effective pursuant
            to this Section 3: (A) within a period of 90 days after the
            effective date of a Registration Statement filed by the Company,
            provided that the Company shall use commercially reasonably efforts
            -------------
            to cause a registration requested hereunder to be declared effective
            promptly following such period if such request is made during such
            period; or (B) if the Company shall furnish to the Initiating Holder
            or Holders a certificate signed by the President of the Company
            stating that in the good faith reasonable judgment of the Board of
            Directors of the Company after consultation with outside counsel,
            the filing of a Registration Statement would, at such time require
            the disclosure of material non-public information relating to the
            Company which, the Company has a bona fide business purpose for
            preserving as confidential or interfere with an existing or
            anticipated acquisition or financing with respect to the Company,
            then


                                      -4-
<PAGE>

            the Company's obligations under this Section 3 shall be deferred
            until the earliest of (i) the date upon which such material
            information is disclosed to the public or ceases to be material,
            (ii) the date upon which such acquisition or financing is
            consummated or, if earlier, the date upon which any such
            interference with such existing or anticipated acquisition or
            financing would no longer exist, or (iii) forty-five (45) days after
            the date of receipt of written request from such Initiating Holder
            or Holders; provided, however, that the Company may not utilize this
                        --------  -------
            deferral right more than once in any twelve-month period.

                  (b) Following receipt of any notice given under this Section 3
            by the Initiating Holders, the Company shall immediately notify in
            writing all Holders that such registration is to be effected and
            shall use commercially reasonable efforts to register under the
            Securities Act for public sale in accordance with the method of
            disposition specified in such notice from requesting Holders, the
            number of shares of Registrable Stock specified in such notice (and
            in all notices received by the Company pursuant hereto). Holders,
            other than the Initiating Holders, shall notify the Company of their
            desire to participate in the registration within twenty (20) days
            of the Company's notice to them. The Company shall use commercially
            reasonable efforts to cause a Registration Statement with respect to
            the Registrable Stock which Holders have requested be registered
            pursuant to this Section 3 no later than forty-five (45) days after
            receiving the notice pursuant to Section 3(a) of the Initiating
            Holders. The Company shall designate the managing underwriter of
            such offering, subject to the approval of the Holders of a majority
            of the shares of Registrable Stock to be sold in such offering,
            which approval shall not be unreasonably withheld or delayed. Each
            Investor shall have the right to request the registration of
            Registrable Stock pursuant to this Section 3 on three occasions
            only, provided, however, that the Company's obligation to register
                  --------  -------
            the Registrable Stock pursuant to this Section 3 in response to a
            particular request shall be deemed satisfied only when a
            Registration Statement or Registration Statements covering all
            shares of Registrable Stock, specified in notices received as
            aforesaid and which have not been withdrawn by the Holders thereof,
            for sale in accordance with the method of disposition specified by
            the Initiating Holders, shall have become effective. A registration
            which does not become effective after the Company has filed a
            Registration Statement with respect thereto solely by reason of the
            refusal of the Initiating Holders to proceed shall be deemed to have
            been effected by the Company at the request of such Initiating
            Holders unless the registration was withdrawn at the request of the
            Holders of a majority of the Registrable Stock to be sold in such
            offering upon learning of a material adverse change in the
            condition, business or prospects of the Company from that known to
            such Holders at the time of their request that makes the proposed
            offering unreasonable in the good faith judgment of a majority in
            interest of such Holders.

                  (c) If the Registration Statement is to cover an underwritten
            distribution and in the good faith judgment of the managing
            underwriter of such public offering the inclusion of all of the
            Registrable Stock requested for inclusion pursuant to this Section 3
            would interfere with the successful marketing of a


                                      -5-
<PAGE>

            smaller number of shares to be offered, then the number of shares of
            Registrable Stock to be included in the offering shall be reduced to
            the required level with the participation in such offering to be
            reduced pro rata among the Holders requesting such registration,
            based upon the number of shares of Registrable Stock requested to be
            included in such registration owned by such Holders. Except for
            registration statements on Form S-4, S-8 or any successors thereto,
            the Company will not file with the Commission any other registration
            statement with respect to its Common Stock, whether for its own
            account or that of other stockholders, from the date of receipt of a
            notice from the Initiating Holders pursuant to this Section 3 until
            the completion of the period of distribution of the registration
            contemplated thereby.

            4. Piggyback Registration. Each time the Company shall determine to
               ----------------------
file a Registration Statement in connection with the proposed offer and sale for
money of any of its securities by it or any of its security holders, the Company
will give written notice thereof to all Holders. Upon the written request of one
or more Holder(s) given within twenty (20) days after the giving of any such
notice by the Company, the Company will use commercially reasonable efforts to
cause all shares of Registrable Stock, the Holders of which have so requested
registration thereof, to be included in such Registration Statement, all to the
extent requisite to permit the sale or other disposition by the prospective
seller or sellers of the Registrable Stock to be so registered, provided that
                                                                --------
if, at any time after giving written notice of its intention to register any
securities and prior to the effective date of the Registration Statement filed
in connection with such registration, the Company shall determine for any reason
not to register or to delay registration of such securities, the Company may, at
its election, give written notice of such determination to each such holder of
Registrable Stock and, thereupon, (i) in the case of a determination not to
register, shall be relieved of its obligation to register any Registrable Stock
in connection with such registration (but not from its obligation to pay any and
all expenses in connection therewith as specified in Section 7 hereof), and (ii)
in the case of a determination to delay registering, shall be permitted to delay
registering any Registrable Stock, for the same period as the delay in
registering such other securities. If the Registration Statement is to cover an
underwritten distribution, the Company shall cause the Registrable Stock
requested for inclusion pursuant to this Section 4 to be included in the
underwriting on the same terms and conditions as the securities otherwise being
sold through the underwriters. If, in the good faith judgment of the managing
underwriter of such public offering, the inclusion of all of the Registrable
Stock requested for inclusion pursuant to this Section 4 would interfere with
the successful marketing of a smaller number of shares to be offered, then the
number of shares of Registrable Stock and other securities to be included in the
offering shall be reduced to the required level by first excluding securities of
any securityholder (other than the Company and the Holders) who proposes to
offer or sell securities in the registered offering, and then excluding on a pro
                                                                             ---
rata basis among the Company, and each Holder of Registrable Stock requesting
- ----
such registration based on the number of shares of Registrable Stock or other
securities the Company and each such Holder proposes to offer or sell in the
registered offering.

            5. Registration on Form S-3.
               ------------------------
            If at any time after the date hereof, (i) a Holder or Holders
request that the Company file a registration statement on Form S-3 or any
successor thereto for a public offering of all or any portion of the shares of
Registrable Stock held by such requesting Holder or


                                      -6-
<PAGE>

Holders, and (ii) the Company is a registrant entitled to use Form S-3 or any
successor thereto to register such shares, then the Company shall use
commercially reasonably efforts to register under the Securities Act on Form S-3
or any successor thereto, for public sale in accordance with the method of
disposition specified in such notice, the number of shares of Registrable Stock
specified in such notice. Whenever the Company is required by this Section 5 to
use commercially reasonable efforts to effect the registration of Registrable
Stock, each of the procedures, requirements and limitations of Section 3 not
otherwise addressed in this Section 5 (including but not limited to the
requirement that the Company notify all Holders from whom notice has not been
received and provide them with the opportunity to participate in the offering
and the requirements of subparagraph (b) of Section 3 but not including the
limitations on the number of registrations the Company is obligated to make
under subparagraph (b) of Section 3) shall apply to such registration. There
shall be no limit on the number of registrations of Registrable Stock which the
Company shall be obligated to effect pursuant to this Section 5.

            6. Registration Procedures. If and whenever the Company is required
               -----------------------
by the provisions of Section 2, 3, 4 or 5 hereof to effect the registration of
shares of Registrable Stock under the Securities Act, the Company will, at its
expense, as expeditiously as possible:

                  (a) In accordance with the Securities Act and the rules and
            regulations of the Commission, prepare and file with the Commission
            a Registration Statement with respect to the Registrable Stock and
            use its best efforts to cause such Registration Statement to become
            effective as promptly as possible and to remain effective until the
            Registrable Stock covered by such Registration Statement has been
            sold, but (other than in the case of the Shelf Registration
            Statement) for no longer than twelve (12) months subsequent to the
            effective date of such Registration Statement, and prepare and file
            with the Commission such amendments to such Registration Statement
            and supplements to the prospectus contained therein as may be
            necessary to keep such Registration Statement effective and such
            Registration Statement and prospectus accurate and complete until
            the Registrable Stock covered by such Registration Statement has
            been sold, but (other than in the case of the Shelf Registration
            Statement) for no longer than twelve (12) months subsequent to the
            effective date of such Registration Statement;

                  (b) If the offering is to be underwritten in whole or in part,
            enter into a written underwriting agreement in form and substance
            reasonably satisfactory to the managing underwriter, if any, of the
            public offering and the Holders participating in such offering;

                  (c) Furnish to the participating Holders and to the
            underwriters such reasonable number of copies of the Registration
            Statement, preliminary prospectus, final prospectus and such other
            documents as such underwriters and participating Holders may
            reasonably request in order to facilitate the public offering of
            such securities;

                  (d) Use commercially reasonable efforts to register or qualify
            the Registrable Stock covered by such Registration Statement under
            such state


                                      -7-
<PAGE>

            securities or blue sky laws of such jurisdictions (i) as shall be
            reasonably appropriate for the distribution of the Registrable Stock
            covered by such Registration Statement or (ii) as such participating
            Holders and underwriters may reasonably request within ten (10) days
            following the original filing of such Registration Statement, except
            that the Company shall not for any purpose be required to execute a
            general consent to service of process, to subject itself to
            taxation, or to qualify to do business as a foreign corporation in
            any jurisdiction where it is not so qualified;

                  (e) Notify the Holders participating in such registration,
            promptly after it shall receive notice thereof, of the date and time
            when such Registration Statement and each post-effective amendment

            forming a part of such Registration Statement has been filed with
            the Commission;

            request of any such participating Holders, any amendments or

            the opinion of counsel representing the Company in such Registration
            (and which counsel is reasonably acceptable to such participating
            Holders), is required under the Securities Act or the rules and
            regulations thereunder in connection with the distribution of the
            Registrable Stock by such participating Holders, but (other than in
            the case of the Shelf Registration Statement) for no longer than
            twelve (12) months subsequent to the effective date of such
            registration:

                  (h) Prepare and promptly file with the Commission, and
            promptly notify such participating Holders of the filing of, such
            amendments or supplements to such Registration Statement or
            prospectus as may be necessary to correct any statements or
            omissions if, at the time when a prospectus relating to such
            Registrable Stock is required to be delivered under the Securities
            Act, any event has occurred as the result of which any such
            prospectus or any other prospectus as then in effect would include
            an untrue statement of a material fact or omit to state any material
            fact required to be stated therein or necessary to make the
            statements therein not misleading;

                  (i) In case any of such participating Holders or any
            underwriter for any such Holders is required to deliver a prospectus
            at a time when the prospectus then in circulation is not in
            compliance with the Securities Act or the rules and regulations of
            the Commission, prepare promptly upon request of any such
            participating Holders such amendments or supplements to such
            Registration Statement and such prospectus as may be necessary in
            order for such prospectus

                  (j) Advise such participating Holders promptly after it shall
            receive notice or obtain knowledge of the issuance of any stop order
            by the Commission or any state securities commission or agency
            suspending the effectiveness of such Registration Statement or the
            initiation or threatening of any proceeding for that purpose and
            promptly use its best efforts to prevent the issuance of any stop
            order or to obtain its withdrawal if such stop order should be
            issued;

                  (k) At the request of any such participating Holder (i)
            furnish to such Holder, if such registration includes an
            underwritten public offering, at the closing provided for in the
            underwriting agreement, copies of any opinion, dated such date, of
            the counsel representing the Company for the purposes of such
            registration, addressed to the underwriters, if any, covering such
            matters with respect to the Registration Statement, the prospectus
            and each amendment or supplement thereto, proceedings under state
            and Federal securities laws, other matters relating to the Company,
            the securities being registered and the offer and sale of such
            securities as are customarily the subject of opinions of issuer's
            counsel provided to underwriters in underwritten public offerings
            or, if the offering is not underwritten, obtain such opinions of
            counsel to the Company addressed to and reasonably satisfactory to

            of the Company, addressed to the underwriters, if any, and to the
            Holder or Holders making such request, stating that they are
            independent certified public accountants within the meaning of the
            Securities Act and dealing with such matters as the underwriters may
            request, or, if the offering is not underwritten, that in the
            opinion of such accountants the financial statements and other
            financial data of the Company included in the Registration Statement
            or the prospectus or any amendment or supplement thereto comply in
            all material respects with the applicable accounting requirements of
            the Securities Act, and additionally covering such other financial
            matters, including information as to the period ending not more than

            respect to the Registration Statement and prospectus, as such
            requesting Holder or Holders may reasonably request;

                  (1) Apply for listing and use commercially reasonable efforts
            to list the Registrable Stock being registered on any national
            securities exchange on which a class of the Company's equity
            securities is listed or, if the Company does not have a class of
            equity securities listed on a national securities exchange, apply
            for qualification and use its best efforts to qualify the
            Registrable Stock being registered for inclusion on the automated
            quotation system of the National Association of Securities Dealers,
            Inc.

                  (a) With respect to each registration effected pursuant to
            Section 2, 3, 4 or 5 hereof, all fees, costs and expenses of and
            incidental to such registration and the public offering in
            connection therewith shall be borne by the Company; provided,
                                                                --------
            however, that Holders and other holders of the Company's stock
            -------
            participating in any such registration shall bear their pro rata
            share of any underwriting discounts and selling commissions, and;
            provided, further, however, that notwithstanding the foregoing, the
            --------  -------  -------
            Company shall not be liable for expenses incurred in connection with
            any registration that shall not have become effective due to a
            revocation by the Holders of Registrable Stock except if such
            registration was revoked or withdrawn by the Holders upon learning
            of a material adverse change in the condition, business or
            prospectus of the Company from that known to such Holders at the
            time of their request for or to be included in such registration
            that makes the proposed offering unreasonable in the good faith
            judgment of such Holders.

                  (b) The fees, costs and expenses of registration to be borne
            as provided in paragraph (a) above shall include, without
            limitation, all registration, filing and NASD fees, printing
            expenses, fees and disbursements of counsel and accountants for the

            of complying with state securities or blue sky laws of any

            8. Indemnification and Contribution.
               --------------------------------

                  (a) To the fullest extent permitted by law, the Company will
            indemnify and hold harmless each Holder whose shares of Registrable
            Stock are included in a Registration Statement pursuant to the
            provisions of this Agreement, each director, officer, partner,
            employee and agent of such Holder, and any underwriter (as defined
            in the Securities Act) for such Holder, and any Person who controls
            such Holder or such underwriter within the meaning of the Securities
            Act, and each of their successors, from and against, and will
            reimburse such Holder, each director, officer, partner, employee and
            agent of such Holder and each such underwriter, controlling Person
            and successor with respect to, any and all claims, actions, demands,
            losses, damages, liabilities, costs and expenses to which such
            Holder, such director, officer, partner, employee or agent of such
            Holder or any such underwriter, controlling Person or successor may
            become subject under the Securities Act or otherwise, insofar as
            such claims, actions, demands, losses, damages, liabilities, costs
            or expenses arise out of or are based upon any untrue statement or
            allegedly untrue statement of any material fact contained in such
            Registration Statement, any prospectus contained therein or any
            amendment or supplement thereto, or arise out of or are based upon
            the omission or alleged


                                      -10-
<PAGE>

            omission to state therein a material fact required to be stated
            therein or necessary to make the statements therein not misleading
            or arise out of any violation by the Company of any rule or
            regulation under the Securities Act applicable to the Company and
            relating to action or inaction required of the Company in connection
            with such registration; provided, however, that the Company will not
                                    --------  -------
            be liable in any such case to the extent that any such claim,
            action, demand, loss, damage, liability, cost or expense arises out
            of or is based upon an untrue statement or alleged untrue statement
            or omission or alleged omission so made in reliance upon and in
            conformity with information furnished by or on behalf of any such
            Holder, such director, officer, partner, employee or agent of such
            Holder, such underwriter, controlling Person or successor in writing
            specifically for use in the preparation thereof, and provided,
                                                                 --------
            further, that this indemnity shall not be deemed to relieve any
            -------
            underwriter of any of its due diligence obligations; and provided
                                                                     --------
            further, that if any claim, action, demand, loss, damage, liability,
            -------
            cost or expense arises out of or is based upon an untrue statement
            or alleged untrue statement or omission or alleged omission
            contained in any preliminary prospectus which did not appear in the
            final prospectus and if the Holder delivered a copy of the
            preliminary prospectus to the person alleging damage and failed to
            deliver a copy of the final prospectus to such persons, the Company
            shall not be liable with respect to the claims of such person.

                  (b) Each Holder of shares of Registrable Stock which are
            included in a registration pursuant to the provisions of this
            Agreement will, severally and not jointly, indemnify and hold
            harmless the Company, each of its directors and officers, each
            underwriter, if any, of the Company's securities covered by such
            registration, each person who controls the Company or such
            underwriter within the meaning of the Securities Act, and each other
            Holder of shares of Registrable Stock which are included in the
            registration, each of the officers, directors, partners, employees
            and agents of each such other Holder and each person controlling
            such other Holder, from and against, and will reimburse such parties
            with respect to, any and all losses, damages, liabilities, costs or
            expenses to which such parties may become subject under the
            Securities Act or otherwise, to the extent that any such loss,
            damage, liability, cost or expense arises out of or is based upon
            any untrue or alleged untrue statement of any material fact
            contained therein or any amendment or supplement thereto, or arises
            out of or is based upon any omission or alleged omission to state
            therein a material fact required to be stated therein or necessary
            to make the statements therein not misleading, in each case to the
            extent, but only to the extent that such untrue statement or alleged
            untrue statement or omission or alleged omission was so made in
            reliance upon and in conformity with written information furnished
            by or on behalf of such Holder for use in the preparation thereof,
            provided that the liability of each Holder hereunder shall be
            limited to the proportion of any such loss, claim, damage, liability
            or expense which is equal to the proportion that the public offering
            price of the shares sold by such Holder under such Registration
            Statement bears to the total public offering price of all securities
            sold thereunder, but not in any event to exceed the net proceeds
            received by such Holder from the sale of shares of Registrable Stock
            covered by a Registration Statement; and provided, further, that
                                                     --------  -------

                                      -11-
<PAGE>

            this indemnity shall not be deemed to relieve any underwriter of any
            of its due diligence obligations.

                  (c) Promptly after receipt by a party to be indemnified
            pursuant to the provisions of paragraph (a) or (b) of this Section 8
            (an "indemnified party") of actual knowledge or notice of the
            commencement of any action involving the subject matter of the
            foregoing indemnity provisions, such indemnified party will, if a
            claim thereof is to be made against the indemnifying party pursuant
            to the provisions of paragraph (a) or (b), notify the indemnifying
            party of the commencement thereof, but the omission so to notify the
            indemnifying party will not relieve it from any liability which it
            may have to an indemnified party otherwise than under this Section 8
            and shall not relieve the indemnifying party from liability under
            this Section 8 unless such indemnifying party is prejudiced by such
            omission. In case such action is brought against any indemnified
            party and it notifies the indemnifying party of the commencement
            thereof, the indemnifying party shall have the right to participate
            in, and, to the extent that it may wish, jointly with any other
            indemnifying party similarly notified, to assume the defense
            thereof, with counsel reasonably satisfactory to such indemnified
            party, and after notice from the indemnifying party to such
            indemnified party of its election so to assume the defense thereof,
            the indemnifying party will not be liable to such indemnified party
            pursuant to the provisions of such paragraphs (a) and (b) for any
            legal or other expense subsequently incurred by such indemnified
            party in connection with the defense thereof other than reasonable
            costs of investigation. Notwithstanding the foregoing, an
            indemnified party shall have the right to retain its own counsel,
            with the fees and expenses to be paid by the indemnifying party, if
            representation of such indemnified party by the counsel retained by
            the indemnifying party would be inappropriate due to actual or
            potential differing interests, as reasonably determined by either
            party, between such indemnified party and any other party
            represented by such counsel in such proceeding. No indemnifying
            party shall be liable to an indemnified party for any settlement of
            any action or claim without the consent of the indemnifying party;
            no indemnifying party may unreasonably withhold its consent to any
            such settlement. No indemnifying party will consent to entry of any
            judgment or enter into any settlement which does not include as an
            unconditional term thereof the giving by the claimant or plaintiff
            to such indemnified party of a release from all liability in respect
            to such claim or litigation.

                  (d) In order to provide for just and equitable contribution to
            joint liability under the Securities Act in any case in which either
            (i) any Holder exercising rights under this Agreement, or any
            controlling Person of any such Holder, makes a claim for
            indemnification pursuant to this Section 8 but it is judicially
            determined (by the entry of a final judgment or decree by a court of
            competent jurisdiction and the expiration of time to appeal or the
            denial of the last right of appeal) that such indemnification may
            not be enforced in such case notwithstanding the fact that this
            Section 8 provides for the indemnification in such case or (ii)
            contribution under the Securities Act may be required on the part of
            any such selling Holder or any such controlling Person in
            circumstances for


                                      -12-
<PAGE>

            which indemnification was provided under this Section 8; then, and
            in each case, the Company and each such Holder, will contribute to
            the aggregate losses, claims, damages or liabilities to which they
            may be subject (after contribution from others) in such proportion
            so that such Holder is responsible for the portion represented by
            the percentage that the public offering price of its Registrable
            Stock offered by the Registration Statement bears to the public
            price of all securities offered by such Registration Statement, and
            the Company is responsible for the remaining portion; provided,
                                                                  --------
            however, that, in any such case, (A) no Person or entity guilty of
            -------
            fraudulent misrepresentation (within the meaning of Section 11(f) of
            the Securities Act) will be entitled to contribution from any Person
            or entity was not guilty of such fraudulent misrepresentation and
            (B) no Holder will be required to contribute any amount in excess of
            the net proceeds of such holder of such Registrable Stock offered by
            it pursuant to such Registration Statement.

            9. Reporting Requirements Under Securities Exchange Act of 1934. The
               ------------------------------------------------------------
Company shall keep effective the registration of its Common Stock under Section
12 of the Exchange Act and shall timely file such information, documents and
reports as the Commission may require or prescribe under Section 13 or 15(d) of
the Exchange Act. The Company shall forthwith upon request furnish any Holder
(i) a written statement by the Company that it has complied with such reporting
requirements, (ii) a copy of the most recent annual or quarterly report of the
Company, and (iii) such other reports and documents filed by the Company with
the Commission as such Holder may reasonably request in availing itself of an
exemption for the sale of Registrable Stock without registration under the
Securities Act. The Company acknowledges and agrees that the purposes of the
requirements contained in this Section 9 are (a) to enable any such Holder to
comply with the current public information requirement contained in Paragraph
(c) of Rule 144 under the Securities Act should such Holder ever wish to dispose
of any of the securities of the Company acquired by it without registration
under the Securities Act in reliance upon Rule 144 (or any other similar or
successor exemptive provision), and (b) to qualify the Company for the use of
Registration Statements on Form S-3. In addition, the Company shall take such
other measures and file such other information, documents and reports, as shall
hereafter be required by the Commission as a condition to the availability of
Rule 144 under the Securities Act (or any similar or successor exemptive
provision hereafter in effect) and the use of Form S-3. The Company also
covenants to use its best efforts, to the extent that it is reasonably within
its power to do so, to qualify for the use of Form S-3. The Company agrees to
use its best efforts to facilitate and expedite transfers of Registrable Stock
pursuant to Rule 144 under the Securities Act (or any similar or successor
exemptive provision hereafter in effect), which efforts shall include timely
notice to its transfer agent to expedite such transfers of Registrable Stock.

            10. Stockholder Information. The Company may require each Holder of
                -----------------------
Registrable Stock as to which any registration is to be effected pursuant to
this Agreement to furnish the Company in a timely manner such information with
respect to such Holder and the distribution of such Registrable Stock as the
Company may from time to time reasonably request in writing and as shall be
required by law or by the Commission in connection therewith.

            11. Company Lock-Up. The Company agrees, if so required by the
